- BACKGROUND: Breastmilk is the recommended aliment for preterm infants. Milk banks provide donated breastmilk for the neonatal care of preterm infants when mother's own milk is not is available. To avoid pathogen transmission, donated breastmilk is heat-treated according to different procedures before administration. There is varying information on the effect of heat treatment on folate in breastmilk. Sufficient folate intake, however, is essential for normal growth and brain development. This study determined and compared the effects of different heat treatments on breastmilk folate content and pattern of individual folate forms.MATERIALS AND METHODS: Donated Swedish breastmilk samples were heat-treated according to three procedures: two low temperature treatments (57°C, 23 minutes; 62.5°C, 12 minutes) and a rapid high temperature treatment (heating to 73°C in boiling water). The folate content and pattern were determined before and after treatment by high-performance liquid chromatography.RESULTS: The folate content in 38 untreated Swedish breastmilk samples was 150±46 nmol/L. Two different folate vitamers were detected: 5-methyltetrahydrofolate (78±7%) and tetrahydrofolate (22±7%). Heat treatment affected only tetrahydrofolate stability and decreased folate content by 15-24%; however, the effects on folate content did not differ among the investigated heat treatment procedures.CONCLUSIONS: Folate losses during heat treatment of human milk were considered acceptable. Yet, native folate content of heat-treated, non-fortified breastmilk supplied only 25% of the recommended daily intake for preterm infants.

- OBJECTIVES: Between 1984 and 1996, Sweden experienced an "epidemic" of clinical celiac disease in children andlt;2 years of age, attributed partly to changes in infant feeding. Whether infant feeding affects disease occurrence and/or the clinical presentation remains unknown. We investigated and compared the total prevalence of celiac disease in 2 birth cohorts of 12-year-olds and related the findings to each cohorts ascertained infant feeding. less thanbrgreater than less thanbrgreater thanMETHODS: A 2-phase cross-sectional screening study was performed in which 13 279 children from 2 birth cohorts participated: children born during the epidemic (1993) and children born after the epidemic (1997). Previously diagnosed cases were reported and confirmed. Blood samples were analyzed for serological markers and children with positive values were referred for small intestinal biopsy. Infant feeding practices in the cohorts were ascertained via questionnaires. Prevalence comparisons were expressed as prevalence ratios. less thanbrgreater than less thanbrgreater thanRESULTS: The total prevalence of celiac disease was 29 in 1000 and 22 in 1000 for the 1993 and 1997 cohorts, respectively. Children born in 1997 had a significantly lower risk of having celiac disease compared with those born in 1993 (prevalence ratio: 0.75; 95% confidence interval: 0.60-0.93; P = .01). The cohorts differed in infant feeding (specifically, in the proportion of infants introduced to dietary gluten in small amounts during ongoing breastfeeding). less thanbrgreater than less thanbrgreater thanCONCLUSIONS: A significantly reduced prevalence of celiac disease in 12-year-olds indicates an option for disease prevention. Our findings suggest that the present infant feeding recommendation to gradually introduce gluten-containing foods from 4 months of age, preferably during ongoing breastfeeding, is favorable.

Journal article (peer-reviewed)abstract
- Objetive: Sweden experienced a marked epidemic of celiac disease between 1984 and 1996 in children younger than 2 years of age, partly explained by changes in infant feeding. The objective of this study was to determine the prevalence of celiac disease in 12-year-olds born during the epidemic (1993), including both symptomatic and screening detected cases.Patients and methods: All sixth-grade children in participating schools were invited (n = 10,041). Symptomatic and, therefore, previously diagnosed celiac disease cases were ascertained through the National Swedish Childhood Celiac Disease Register and/or medical records. All serum samples were analyzed for antihuman tissue transglutaminase (tTG)-IgA (Celikey), and serum-IgA, and some for tTG-IgG and endomysial antibodies. A small intestinal biopsy was recommended for all children with suspected undiagnosed celiac disease.Results: Participation was accepted by 7567 families (75%). Previously diagnosed celiac disease was found in 67 children; 8.9/1000 (95% confidence interval [CI] 6.7-11). In another 192 children, a small intestinal biopsy was recommended and was performed in 180. Celiac disease was verified in 145 children, 20/1000 (95% CI 17-23). The total prevalence was 29/1000 (95% CI 25-33).Conclusions: The celiac disease prevalence of 29/1000 (3%)-with two thirds of cases undiagnosed before screening-is 3-fold higher than the usually suggested prevalence of 1%. When these 12-year-olds were infants, the prevailing feeding practice was to introduce gluten abruptly, often without ongoing breast-feeding, which might have contributed to this unexpectedly high prevalence.

Effects of iron supplementation of LBW infants on cognition and behavior at 3 years
- 2013
-
In: Pediatrics. - : American Academy of Pediatrics (AAP). - 0031-4005 .- 1098-4275. ; 131, s. 47-55

Journal article (peer-reviewed)abstract
- OBJECTIVE: Low birth weight (LBW) infants are at increased risk of cognitive and behavioral problems and at risk for iron deficiency, which is associated with impaired neurodevelopment. We hypothesized that iron supplementation of LBW infants would improve cognitive scores and reduce behavioral problems. METHODS: In a randomized controlled trial, 285 marginally LBW (2000-2500 g) infants received 0, 1, or 2 mg/kg/day of iron supplements from 6 weeks to 6 months of age. At 3.5 years of age, these infants and 95 normal birth weight controls were assessed with a psychometric test (Wechsler Preschool and Primary Scale of Intelligence) and a questionnaire of behavioral problems (Child Behavior Checklist; CBCL). RESULTS: There were no significant differences in IQ between the LBW groups or LBW infants versus controls. Mean (SD) full-scale IQ was 105.2 (14.5), 104.2 (14.7), and 104.5 (12.7) in the placebo, 1 mg, and 2 mg groups, respectively (P = .924). However, for behavioral problems, there was a significant effect of intervention. The prevalence of children with CBCL scores above the US subclinical cutoff was 12.7%, 2.9%, and 2.7% in the placebo, 1-mg, and 2-mg groups, respectively (P = .027), compared with 3.2% in controls. Relative risk (95% confidence interval) for CBCL score above cutoff in placebo-treated children versus supplemented was 4.5 (1.4-14.2). CONCLUSIONS: Early iron supplementation of marginally LBW infants does not affect cognitive functions at 3.5 years of age but significantly reduces the prevalence of behavioral problems. The study suggests a causal relation between infant iron deficiency and later behavioral problems.

Journal article (peer-reviewed)abstract
- Background: High intake of protein and low intake of plant-based foods during complementary feeding can contribute to negative long-term health effects.Objectives: To investigate the effects of a protein-reduced, Nordic complementary diet on body composition, growth, biomarkers, and dietary intake, compared with current Swedish dietary recommendations for infants at 12 and 18 mo.Methods: Healthy, term infants (n = 250) were randomly allocated to either a Nordic group (NG) or a conventional group (CG). From 4 to 6 mo, NG participants received repeated exposures of Nordic taste portions. From 6 to 18 mo, NG was supplied with Nordic homemade baby food recipes, protein-reduced baby food products, and parental support. CG followed the current Swedish dietary recommendations. Measurements of body composition, anthropometry, biomarkers, and dietary intake were collected from baseline and at 12 and 18 mo.Results: Of the 250 infants, 82% (n = 206) completed the study. There were no group differences in body composition or growth. In NG, protein intake, blood urea nitrogen and plasma IGF-1 were lower compared to CG at 12 and 18 mo. Infants in NG consumed 42% to 45% more fruits and vegetables compared to CG at 12 and 18 mo, which was reflected in a higher plasma folate at 12 and 18 mo. There were no between-group differences in EI or iron status.Conclusions: Introduction of a predominantly plant-based, protein-reduced diet as part of complementary feeding is feasible and can increase fruit and vegetable intake.This trial was registered at clinicaltrials.gov as NCT02634749.

Journal article (peer-reviewed)abstract
- Early life is critical for developing healthy eating patterns. This study aimed to investigate the effects of a Nordic, protein-reduced complementary diet (ND) compared to a diet following the current Swedish dietary guidelines on eating patterns and food acceptance. At 4–6 months (mo) of age infants were randomized to a Nordic group (NG, n = 41) or a Conventional group (CG, n = 40), and followed until 18 mo of age. Daily intake of fruits and vegetables (mean ± sd) at 12 mo was significantly higher in the NG compared to the CG: 341 ± 108 g/day vs. 220 ± 76 g/day (p < 0.001), respectively. From 12 to 18 mo, fruit and vegetable intake decreased, but the NG still consumed 32% more compared to the CG: 254 ± 99 g/day vs. 193 ± 67 g/day (p = 0.004). To assess food acceptance, both groups were tested with home exposure meals at 12 and 18 mo. No group differences in acceptance were found. We find that a ND with parental education initiates healthy eating patterns during infancy, but that the exposure meal used in the present study was insufficient to detect major differences in food acceptance. This is most likely explained by the preparation of the meal. Nordic produce offers high environmental sustainability and favorable taste composition to establish healthy food preferences during this sensitive period of early life.

Protein-Reduced Complementary Foods Based on Nordic Ingredients Combined with Systematic Introduction of Taste Portions Increase Intake of Fruits and Vegetables in 9 Month Old Infants : A Randomised Controlled Trial
- 2019
-
In: Nutrients. - : MDPI. - 2072-6643. ; 11:6
-
Journal article (peer-reviewed)abstract
- Fruits and vegetables are healthy foods but under-consumed among infants and children. Approaches to increase their intake are urgently needed. This study investigated the effects of a systematic introduction of taste portions and a novel protein-reduced complementary diet based on Nordic foods on fruit and vegetable intake, growth and iron status to 9 months of age. Healthy, term infants (n = 250) were recruited and randomly allocated to either a Nordic diet group (NG) or a conventional diet group (CG). Infants were solely breast- or formula-fed at study start. From 4 to 6 months of age, the NG followed a systematic taste portions schedule consisting of home-made purées of Nordic produce for 24 days. Subsequently, the NG was supplied with baby food products and recipes of homemade baby foods based on Nordic ingredients but with reduced protein content compared to the CG. The CG was advised to follow current Swedish recommendations on complementary foods. A total of 232 participants (93%) completed the study. The NG had significantly higher intake of fruits and vegetables than the CG at 9 months of age; 225 ± 109 g/day vs. 156 ± 77 g/day (p < 0.001), respectively. Energy intake was similar, but protein intake was significantly lower in the NG (−26%, p < 0.001) compared to the CG. This lower protein intake was compensated for by higher intake of carbohydrate from fruits and vegetables. No significant group differences in growth or iron status were observed. The intervention resulted in significantly higher consumption of fruits and vegetables in infants introduced to complementary foods based on Nordic ingredients.

- Background: What we eat as infants and children carries long-term consequences. Apart from breastfeeding, the composition of the complementary diet, i.e. the foods given to the infant during the transition from breast milk/infant formula to regular family foods affects the child's future health. A high intake of protein, a low intake of fruits, vegetables and fish and an unfavorable distribution between polyunsaturated and saturated fats are considered to be associate with health risks, e.g. obesity, type 2 diabetes and dyslipidemia later in life.Methods: In a randomized, controlled study from 6 to 18months of age we will compare the currently recommended, Swedish complementary diet to one based on Nordic foods, i.e. an increased intake of fruits, berries, vegetables, tubers, whole-grain and game, and a lower intake of sweets, dairy, meat and poultry, with lower protein content (30% decrease), a higher intake of vegetable fats and fish and a systematic introduction of fruits and greens. The main outcomes are body composition (fat and fat-free mass measured with deuterium), metabolic and inflammatory biomarkers (associated with the amount of body fat) in blood and urine, gut microbiota (thought to be the link between early diet, metabolism and diseases such as obesity and insulin resistance) and blood pressure.We will also measure the participants' energy and nutrient intake, eating behavior and temperament through validated questionnaires, acceptance of new and unfamiliar foods through video-taped test meals and assessment of cognitive development, which we believe can be influenced through an increased intake of fish and milk fats, notably milk fat globule membranes (MFGM).Discussion: If the results are what we expect, i.e. improved body composition and a less obesogenic, diabetogenic and inflammatory metabolism and gut microbiota composition, a more sustainable nutrient intake for future health and an increased acceptance of healthy foods, they will have a profound impact on the dietary recommendations to infants in Sweden and elsewhere, their eating habits later in life and subsequently their long-term health.Trial registration: NCT02634749. Registration date 18 December 2015.

Mutation of conserved cysteines in the Ly6 domain of GPIHBP1 in familial chylomicronemia

Journal article (peer-reviewed)abstract
- We investigated a family from northern Sweden in which three of four siblings have congenital chylomicronemia. Lipoprotein lipase (LPL) activity and mass in pre- and post-heparin plasma were low, and LPL release into plasma after heparin injection was delayed. LPL activity and mass in adipose tissue biopsies appeared normal. [35S]Methionine incorporation studies on adipose tissue showed that newly synthesized LPL was normal in size and normally glycosylated. Breast milk from the affected female subjects contained normal to elevated LPL mass and activity levels. The milk had a lower than normal milk lipid content, and the fatty acid composition was compatible with the milk lipids being derived from de novo lipogenesis, rather than from the plasma lipoproteins. Given the delayed release of LPL into the plasma after heparin, we suspected that the chylomicronemia might be caused by mutations in GPIHBP1. Indeed, all three affected siblings were compound heterozygotes for missense mutations involving highly conserved cysteines in the Ly6 domain of GPIHBP1 (C65S and C68G). The mutant GPIHBP1 proteins reached the surface of transfected CHO cells but were defective in their ability to bind LPL (as judged by both cell-based and cell-free LPL binding assays). Thus, the conserved cysteines in the Ly6 domain are crucial for GPIHBP1 function.

Journal article (peer-reviewed)abstract
- Background: Compositional changes in the early‐life gut microbiota have been implicated in IgE‐associated allergic diseases, but there is lack of longitudinal studies. We examined gut microbiota development from infancy to school age in relation to onset of IgE‐associated allergic diseases. At 8 years of age, we also examined the relationship between gut microbiota and T‐cell regulation, estimated as responses to polyclonal T‐cell activation.Methods: Stool samples were collected from 93 children at 4, 6, 13 months, and 8 years of age. The gut microbiota was profiled using 16S rRNA gene sequencing. Peripheral blood was drawn from all children, and mononuclear cells were polyclonally activated. Levels of IL‐10 and FOXP3 mRNA copies were determined using real‐time quantitative reverse transcriptase‐PCR.Results: At 8 years of age, 21 children were diagnosed with IgE‐associated allergic disease and 90% displayed allergic comorbidity. Seventy‐two children were nonallergic and nonsensitized. Statistical tests with multiple testing corrections demonstrated temporal underrepresentation of Ruminococcus and consistent underrepresentation of Bacteroides, Prevotella, and Coprococcus in allergic compared to nonallergic children from infancy to school age. The gut microbiota of the allergic 8‐year‐olds was enriched in Bifidobacteriumand depleted of Lactobacillus, Enterococcus, and Lachnospira. In allergic 8‐year-olds, Faecalibacterium correlated with IL‐10 mRNA levels (rs = 0.49, Padj = 0.02) with the same trend for FOXP3 (rs = 0.39, Padj = 0.08).Conclusions: We identified both temporal and long‐term variation in the differential abundance of specific bacterial genera in children developing IgE‐associated allergic disease. Improved dietary interventions aiming at expanding immune‐modulatory taxa could be studied for prevention of allergic disease.

Journal article (peer-reviewed)abstract
- GOALS OF WORK: The purpose of this study was to better understand various variables related to food intake and eating problems in children with cancer during their chemotherapy. PATIENTS AND METHODS: Twenty-two consecutively admitted children, diagnosed with cancer and undergoing chemotherapy, participated in this study. Twenty-one of them, their parents and attending nurses participated in semi-structured interviews. Ten of the children underwent a taste acuity test, and recognition thresholds for the four basic tastes were determined. MAIN RESULTS: The shared view of both children and parents was that altered taste was the predominant cause of the eating problems. In contrast, the nurses perceived that nausea was the most important cause of the children's eating problems. In addition, psychological aspects such as learned food aversions and negative attitudes towards hospital food were regarded as important by children, parents and nurses. The taste test showed that the patients had higher thresholds for bitter taste and made more taste recognition errors compared to controls. CONCLUSIONS: Changes seem to exist both in the primary gustatory sense as well as in food perception in paediatric cancer patients undergoing chemotherapy. Single solutions, such as efforts to serve "tasty food", do not suffice alone. A more effective solution may be to combine different strategies and combinations of oral, enteral and parenteral nutrition should be considered to prevent malnutrition.

Effects of age, sex and diet on salivary nitrate and nitrite in infants
- 2020
-
In: Nitric oxide. - : Elsevier. - 1089-8603 .- 1089-8611. ; 94, s. 73-78
-
Journal article (peer-reviewed)abstract
- The inorganic anions nitrate and nitrite are oxidation products from endogenous nitric oxide (NO) generation and constituents in our diet. A nitrate-nitrite-NO pathway exists in which nitrate can be serially reduced to bioactive NO. The first step of this pathway occurs in the oral cavity where oral bacteria convert salivary nitrate to nitrite, whereafter nitrite is reduced to NO systemically by several enzymatic and non-enzymatic pathways. Data are scarce regarding salivary levels and oral conversion capacity of these anions in infants. We measured salivary nitrate and nitrate in infants at 4 and 12 months of age and related values to age, sex, dietary pattern and oral microbiome. Saliva was collected from a total of 188 infants at 4 and 12 months of age. Salivary nitrate, nitrite and nitrite/nitrate ratio as a measure of oral nitrate-reducing capacity were analyzed by HPLC and related to age, sex, type of diet (breast milk or formula) and oral microbiome. There was no difference in salivary nitrate, nitrite or nitrite/nitrate ratio between boys and girls at any age. At 4 months levels of these parameters were lower than what has been described in adults but they had all increased significantly at 12 months of age. At 4 months of age salivary nitrite/nitrate ratio was lower in breast-fed compared to formula-fed infants, but these differences disappeared at 12 months. Several bacterial species were associated with oral nitrate reducing capacity including Prevotella, Veillonella, Alloprevotella and Leptotrichia. We conclude that in infants there is an increase in salivary nitrate and nitrite as well as in oral nitrate-reductase capacity during the first year of life. Differences observed at 4 months of age between breast-fed and formula-fed infants disappear at one year of age.

Journal article (other academic/artistic)abstract
- Microbial exposure is necessary for the development of normal immune function, which has driven the idea of using probiotics for treatment and prevention of immune-mediated diseases in infancy and childhood. Mounting evidence indicates that probiotics have immunomodulatory effects. However, the mechanisms are still poorly understood. Specific antibody response is a valuable proxy for immune system maturation status in infancy. We aimed at determining the impact of Lactobacillus F19 (LF19) during weaning on infections and IgG antibody responses to routine vaccines. In a double-blind, placebo-controlled randomized intervention trial, infants were fed cereals with (n = 89) or without LF19 (n = 90) from 4 to 13 months of age. Infants were immunized with DTaP (diphtheria and tetanus toxoid and acellular pertussis), polio and Hib-conjugate vaccines at (3), 5(1/2) and 12 months of age. We assessed the number of days with infections, antibiotic prescriptions and antibody concentrations to Hib capsular polysaccharide (HibPS), diphtheria toxin (D) and tetanus toxoid (T) before and after the second and third doses. Days with infectious symptoms did not differ between the groups. Days with antibiotic prescriptions were fewer in the LF19 group (p = 0.044). LF19 enhanced anti-D concentrations when adjusting for breastfeeding duration and colonization with LF19 (p = 0.024). There was an interaction of the intervention and colonization with LF19 on anti-T concentrations during the course of vaccination (p = 0.035). The anti-HibPS concentrations were higher after the first and second dose of Hib vaccine in infants breastfed <6 months compared with those breastfed > or =6 months (p < 0.05), with no effect by LF19. In conclusion, feeding LF19 did not prevent infections, but increased the capacity to raise immune responses to protein antigens, with more pronounced effects in infants breastfed <6 months.

Journal article (peer-reviewed)abstract
- Aim: To investigate effects of iron-fortified foods (FFs) and medicinal iron drops (MD) on iron status in infants. Methods: Data from one MD and one FF study were compared. Infants were divided into groups depending on the predominant source and amount of dietary iron during 6–9 months of age: MD: Medicinal iron drops (1 mg/kg/day). FF: iron intake >1.3 mg/kg/day, predominantly from FF and no iron supplements. Low iron (LI) group: iron intake <1.3 mg/kg/day and no iron supplements. Results: Mean iron intake did not differ between MD (n = 30) and FF (n = 35) groups but was lower in the LI (n = 232) group. The FF group had significantly higher mean Hb at 9 months compared to the MD and LI groups (120 vs. 115 g/L and 120 vs. 116 g/L, respectively, p ≤ 0.005). The MD group had significantly higher mean SF at 9 months compared to the FF and the LI groups (46 vs. 23 μg/L and 46 vs. 26 μg/L, respectively, p < 0.001). Conclusions: Our results suggest that, in healthy, term, nonanaemic 6–9-month-old infants, iron given as medicinal iron drops is primarily deposited into iron stores while iron given as iron-fortified foods is primarily utilized for Hb synthesis.

Journal article (peer-reviewed)abstract
- BACKGROUND: Supplementation of formula with bovine milk fat globule membranes has been shown to narrow the gap in immunological and cognitive development between breast-fed and formula-fed infants.METHOD: In a double-blinded randomized controlled trial 160 formula-fed infants received an experimental formula (EF), supplemented with bovine milk fat globule membranes, or standard formula until 6 months of age. A breast-fed reference group was recruited. Lipidomic analyses were performed on plasma and erythrocyte membranes at 6 months and on serum at 4 and 12 months of age.RESULTS: At 6 months of age, we observed a significant separation in the plasma lipidome between the two formula groups, mostly due to differences in concentrations of sphingomyelins (SM), phosphatidylcholines (PC), and ceramides, and in the erythrocyte membrane lipidome, mostly due to SMs, PEs and PCs. Already at 4 months, a separation in the serum lipidome was evident where SMs and PCs contributed. The separation was not detected at 12 months.CONCLUSIONS: The effect of MFGM supplementation on the lipidome is likely part of the mechanisms behind the positive cognitive and immunological effects of feeding the EF previously reported in the same study population.

- OBJECTIVES: The aim was to investigate age-dependent serum levels and occurrence of elevated celiac disease (CD)-related antibodies in young children, to define the optimal serological procedure when selecting for small intestinal biopsy. PATIENTS AND METHODS: Included were 428 children with biopsy verified CD (median age 16 months; range 7.5 months-14 years) and 216 controls (median age 2.7 years; range 8.5 months-14.6 years). Immunoglobulin (Ig) A antibodies against gliadin (AGA-IgA), tissue transglutaminase (tTG-IgA), and endomysium (EMA-IgA) were analysed. RESULTS: Increased serum AGA-IgA levels were found in 411 of 428 CD cases, tTG-IgA in 385 of 428, and EMA-IgA in 383 of 428. In the control group, 11 of 216 had increased levels of AGA-IgA, 5 of 216 of tTG-IgA, and 8 of 216 of EMA-IgA. In CD children younger than 18 months, elevated AGA-IgA occurred in 97% and elevated tTG-IgA and EMA-IgA were found in 83% of the cases. Conversely, in CD children older than 18 months, elevated AGA-IgA occurred in 94%, and elevated tTG-IgA and EMA-IgA were found in 99% of the cases. CONCLUSIONS: In children older than 18 months, both tTG-IgA and EMA-IgA are sufficiently accurate to be used as a single antibody marker, whereas a large proportion of younger children with CD lack these antibodies. Therefore, when selecting children for small intestinal biopsy, the detection of a combination of AGA-IgA and tTG-IgA is optimal for identifying untreated CD in children younger than 18 months.

- 2008
-
In: Acta Paediatrica. - : Wiley. - 0803-5253 .- 1651-2227. ; 97:5, s. 630-5

Journal article (peer-reviewed)abstract
- AIM: To compare the expression levels of the adiponectin and peroxisome proliferator -activated receptor gamma (PPARgamma) genes in subcutaneous adipose tissue (SC) and omental adipose tissue (OM) in children with relation to age and anthropometric variables. METHODS: Paired biopsies (SC and OM) were obtained from 53 children (age 0.2-14 years, BMI 12.5-25.8 kg/m(2)). Adiponectin and PPARgamma mRNA levels in adipose tissue were measured by real-time PCR. RESULTS: In overweight, but not in normal weight children, the median adiponectin mRNA level was significantly lower in OM [0.51 (0.1-2.17)] compared to SC [1.29 (0.16-5.08)], (p = 0.03). Adiponectin mRNA levels were strongly associated with PPARgamma mRNA levels in both SC (r = 0.73, p < 0.001) and OM (r = 0.78, p < 0.001). CONCLUSIONS: The lower adiponectin expression in OM relative to SC in overweight children indicates that metabolic-endocrine alterations begin already in childhood. The close association between adiponectin and PPARgamma expression supports the hypothesis this transcription factor is involved in adiponectin gene regulation.

Depot-specific messenger RNA expression of 11 beta-hydroxysteroid dehydrogenase type 1 and leptin in adipose tissue of children and adults
- 2007

In: International Journal of Obesity. - London : Macmillan. - 0307-0565 .- 1476-5497. ; 31:5, s. 820-828

Journal article (peer-reviewed)abstract
- Objective: To compare expression of messenger RNA (mRNA) coding for the cortisol regenerating enzyme 11-hydroxysteroid dehydrogenase type 1 (11-HSD1), and the adipocytokines leptin and resistin in paired biopsies of subcutaneous adipose tissue (SC) and omental adipose tissue (OM) from children. Design: Paired biopsies (SC and OM) were obtained from 54 children (age 0.17–16 years, body mass index (BMI) 12.5–28.3 kg/m2, BMI standard deviation score (SDS) -2.5–4.5) and 16 adults (age 27–79 years, BMI 19–46 kg/m2) undergoing open abdominal surgery. mRNA levels of 11-HSD1, leptin and resistin were measured using quantitative real-time polymerase chain reaction (PCR). Results: 11-HSD1 mRNA level was higher in OM than in SC (P<0.05), whereas leptin mRNA was higher in SC than in OM (P<0.001). There was no difference in the resistin mRNA level between SC and OM. These results were consistent in children and adults. In children, 11-HSD1 mRNA in SC was positively associated with BMI SDS (P<0.05), whereas in OM it was positively associated with age (P<0.05). The association between 11-HSD1 expression and age remained significant after adjustment for BMI SDS and gender. Leptin mRNA was positively associated with BMI SDS (SC:P<0.001, OM: P<0.001) but not with age in children. In multiple regression analyses, including anthropometric variables and age, BMI SDS was independently associated with mRNA levels of 11-HSD1 (P<0.05) and leptin (P<0.001) in SC. When normal weight and overweight children were analyzed separately, 11-HSD1 mRNA levels were positively associated with leptin in OM in the overweight group (P<0.05). Conclusion: There are depot-specific differences in mRNA levels of 11-HSD1 and leptin in children and adults. The positive association of 11-HSD1 mRNA in OM with age may reflect a causal role in visceral fat accumulation during growth. Increasing 11-HSD1 and leptin mRNA in SC with increasing BMI SDS could suggest that the risk of metabolic consequences of obesity may be established early in life.

Early infections are associated with increased risk for celiac disease : an incident case-referent study
- 2012
-
In: BMC Pediatrics. - : Springer Science and Business Media LLC. - 1471-2431. ; 12, s. 194-
-
Journal article (peer-reviewed)abstract
- Background: Celiac disease is defined as a 'chronic small intestinal immune-mediated enteropathy precipitated by exposure to dietary gluten in genetically predisposed individuals'. Sweden has experienced an "epidemic" of celiac disease in children below two years of age. Celiac disease etiology is considered multifactorial; however, little is known regarding potential risk-or protecting factors. We present data on the possible association between early infectious episodes and celiac disease, including their possible contribution to the Swedish celiac disease epidemic. Methods: A population-based incident case-referent study (475 cases, 950 referents) with exposure information obtained via a questionnaire (including family characteristics, infant feeding, and the child's general health) was performed. Celiac disease cases were diagnosed before two years of age, fulfilling the diagnostic criteria of the European Society for Pediatric Gastroenterology, Hepatology and Nutrition. Referents were randomly selected from the national population register after fulfilling matching criteria. The final analyses included 954 children, 373 (79%) cases and 581 (61%) referents, with complete information on main variables of interest in a matched set of one case with one or two referents. Results: Having three or more parental-reported infectious episodes, regardless of type of infection, during the first six months of life was associated with a significantly increased risk for later celiac disease, and this remained after adjusting for infant feeding and socioeconomic status (odds ratio [OR] 1.5; 95% confidence interval [CI], 1.1-2.0; P=0.014). The celiac disease risk increased synergistically if, in addition to having several infectious episodes, infants were introduced to dietary gluten in large amounts, compared to small or medium amounts, after breastfeeding was discontinued (OR 5.6; 95% CI, 3.1-10; P<0.001). Conclusion: This study suggests that having repeated infectious episodes early in life increases the risk for later celiac disease. In addition, we found a synergistic effect between early infections and daily amount of gluten intake, more pronounced among infants for whom breastfeeding had been discontinued prior to gluten introduction. Regarding contribution to the Swedish celiac disease epidemic, which partly was attributed to concurrent changes in infant feeding, early infections probably made a minor contribution via the synergistic effect with gluten amount.

Early vaccinations are not risk factors for Celiac Disease
- 2012

Journal article (peer-reviewed)abstract
- OBJECTIVES: To investigate if changes in the national Swedish vaccination program coincided with changes in the celiac disease (CD) incidence rate in infants (ie, the Swedish CD Epidemic), and to assess the potential association between these vaccinations and CD risk.METHODS: All studies were based on the National Swedish Childhood Celiac Disease Register. Using an ecological approach, we plotted changes over time in the national vaccination program in the graph displaying CD incidence rate. A population-based incident case-referent study of invited infants was performed. Exposure information was received through a questionnaire and child health clinic records. Vaccines explored were diphtheria/tetanus, pertussis (acellular), polio (inactivated), Haemophilus influenzae type b (conjugated), measles/mumps/rubella, and live attenuated bacillus Calmette-Guerin (BCG) in children with increased tuberculosis risk. Findings were subjected to a birth cohort analysis.RESULTS: Introduction of pertussis vaccine coincided in time with decreasing CD incidence rates. In the infant case-referent study, however, neither vaccination against pertussis (odds ratio 0.91; 95% confidence interval 0.60-1.4), nor against Haemophilus influenzae type b or measles/mumps/rubella was associated with CD. Coverage for the diphtheria/tetanus and polio vaccines was 99%. BCG was associated with reduced risk for CD (adjusted odds ratio 0.54; 95% confidence interval 0.31-0.94). Discontinuation of general BCG vaccination did not affect the cumulative incidence of CD at age 15 years.CONCLUSIONS: Early vaccinations within the national Swedish program were not associated with CD risk, nor could changes in the program explain the Swedish epidemic. A protective effect by BCG was suggested, which could be subject to further studies. Pediatrics 2012;130:e63-e70

Does inadequate maternal iron or DHA status have a negative impact on an infant's functional outcomes?
- 2006
-
In: Acta Paediatr. - 0803-5253. ; 95:2, s. 137-44
-
Journal article (other academic/artistic)abstract
- Marginal intake of iron and omega-3 long-chain fatty acids (DHA) is prevalent among pregnant women. It is not clear to what extent poor iron or DHA status during pregnancy impacts on an infant's functional outcomes. A few studies suggest that inadequate maternal iron or DHA status may be associated with suboptimal functional outcomes in infants. In addition, there is a lack of prospective studies using randomized, double-blind design or experimental studies with appropriate animal models. Although both nutrients are involved in early brain development and their metabolism is interrelated, no study has examined the interaction between iron and omega-3 fatty acids during pregnancy. CONCLUSION: Long-term studies on large cohorts of pregnant women and their infants are needed to determine whether inadequate iron or DHA status during pregnancy is detrimental to infant neurodevelopment.

Noncontaminated dietary oats may hamper normalization of the intestinal immune status in childhood celiac disease
- 2014
-
In: Clinical and Translational Gastroenterology. - : Ovid Technologies (Wolters Kluwer Health). - 2155-384X. ; 5
-
Journal article (peer-reviewed)abstract
- OBJECTIVES: Life-long, strict gluten-free diet (GFD) is the only treatment for celiac disease (CD). Because there is still uncertainty regarding the safety of oats for CD patients, the aim was to investigate whether dietary oats influence the immune status of their intestinal mucosa.METHODS: Paired small intestinal biopsies, before and after >11 months on a GFD, were collected from children with CD who were enrolled in a randomized, double-blind intervention trial to either of two diets: standard GFD (GFD-std; n=13) and noncontaminated oat-containing GFD (GFD-oats; n=15). Expression levels of mRNAs for 22 different immune effector molecules and tight junction proteins were determined by quantitative reverse transcriptase (RT)-PCR.RESULTS: The number of mRNAs that remained elevated was higher in the GFD-oats group (P=0.05). In particular, mRNAs for the regulatory T cell (Treg) signature molecules interleukin-10 (IL-10) and transforming growth factor-β1 (TGF-β1), the cytotoxicity-activating natural killer (NK) receptors KLRC2/NKG2C and KLRC3/NKG2E, and the tight junction protein claudin-4 remained elevated. Between the two groups, most significant differences were seen for claudin-4 (P=0.003) and KLRC3/NKG2E (P=0.04).CONCLUSIONS: A substantial fraction of pediatric CD patients seem to not tolerate oats. In these patients, dietary oats influence the immune status of the intestinal mucosa with an mRNA profile suggesting presence of activated cytotoxic lymphocytes and Tregs and a stressed epithelium with affected tight junctions. Assessment of changes in levels of mRNA for claudin-4 and KLC3/NKG2E from onset to after a year on oats containing GFD shows promise to identify these CD patients.

Nutrient intake and weight development in children during chemotherapy for malignant disease
- 1997
-
In: Oral Oncology. - 1368-8375 .- 1879-0593. ; 33:5, s. 364-8
-
Journal article (peer-reviewed)abstract
- The aim of the study was to assess the actual daily oral intake of energy, protein, fat and carbohydrate in relation to current recommendations in children with malignant disease during chemotherapy and to follow their weight development. Dietary information was collected for 21 consecutive days via 7-day recording in 14 children, aged 5-16 years. The number of days with loss of appetite, vomiting, and the number of days on anti-emetic drugs were also recorded. The average daily energy intake decreased from 91% of the recommendation of the Swedish Nutrition Recommendations (SNR), before chemotherapy to 69% after start of chemotherapy. During days spent at home, the energy intake increased to 77% of SNR. Twenty-two per cent of the total energy intake during the hospital days came from sucrose. On average, the children experienced loss of appetite on 50% of the days, vomiting on 12%, and received anti-emetic drugs on 38%. On admission, the average SD score for body weight for the whole group was -0.09. The mean weight reduction after 1 week was 0.19 SD (P = 0.05) compared to the admission weight. The weight reduction 6 weeks (n = 10) and 3 months (n = 13) after the start of chemotherapy was 0.10 SD and 0.37 SD (P = 0.04), respectively

Journal article (peer-reviewed)abstract
- Five obligately anaerobic, Gram-negative, saccharolytic and proteolytic, non-spore-forming bacilli (CD3:27, CD3:28T, CD3:33, CD3:32 and CD3:34) are described. All five strains were isolated from the small intestine of a female child with celiac disease. The cells of the five strains were observed to be short rods or coccoid cells with longer filamentous forms seen sporadically. The organisms produced acetic acid and succinic acid as major metabolic end products. Phylogenetic analysis, based on comparative 16S rRNA gene sequence analysis revealed close relationships between CD3:27, CD3:28T and CD3:33 on one hand, between CD3:32 and P. histicola CCUG 55407T and between CD3:34 and P. melaninogenica CCUG 4944BT on the other. The strains CD3:27, CD3:28T and CD3:33 were clearly different from any other species within the genus Prevotella and most closely related to but distinct from P. melaninogenica. Based on 16S rRNA gene, RNA polymerase β-subunit gene and 60-kDa chaperonin protein subunit gene sequencing, phenotypic, chemical and biochemical properties strains CD3:27, CD3:28T and CD3:33 have been determined to represent a novel species within the genus Prevotella, named Prevotella jejuni sp. nov. Strain CD3:28T (CCUG 60371T = DSM 26989T) is the type strain of the proposed new species. All five strains were able to form homologous aggregates, in which tube-like structures were connecting individual bacteria cells. The five strains were able to bind to human intestinal carcinoma cell lines at 37 °C.

Journal article (peer-reviewed)abstract
- To decrease BMI in overweight and obese children, improved dietary intake and increased physical activity are key elements. Our objective was to evaluate the impact of a 1-y food and physical activity intervention on energy and macronutrient intake in overweight and obese children. A randomized open trial was conducted with 92 overweight or obese 10.4 ± 1.08-y-old children. The intervention included 14 group sessions with different themes regarding food and physical activity. Dietary intake was assessed with diet history interviews covering 14 d at baseline and 4-d food records after 1 y and was evaluated according to national dietary recommendations. The control group participated in the same measurements as the intervention group but did not take part in group sessions. After 1 y, both groups had decreased their energy intake (EI) relative to total energy expenditure, but the effect was more pronounced for the intervention group than for the control group. At 1 y follow-up, a larger proportion of children in the intervention group compared with the control group met the recommended intake of refined sugar (P = 0.019). However, the groups did not differ in the proportion children who met the recommended intake of dietary fiber. Further, SFA intake relative to total EI did not differ between the groups at 1 y follow-up. In conclusion, despite a rather comprehensive intervention, only modest effects were achieved with respect to reduced EI and improved macronutrient intake.

Feeding preterm infants after hospital discharge : a commentary by the ESPGHAN Committee on Nutrition.

-
In: Journal of pediatric gastroenterology and nutrition. - : Ovid Technologies (Wolters Kluwer Health). - 1536-4801 .- 0277-2116. ; 42:5, s. 596-603

Journal article (peer-reviewed)abstract
- Survival of small premature infants has markedly improved during the last few decades. These infants are discharged from hospital care with body weight below the usual birth weight of healthy term infants. Early nutrition support of preterm infants influences long-term health outcomes. Therefore, the ESPGHAN Committee on Nutrition has reviewed available evidence on feeding preterm infants after hospital discharge. Close monitoring of growth during hospital stay and after discharge is recommended to enable the provision of adequate nutrition support. Measurements of length and head circumference, in addition to weight, must be used to identify those preterm infants with poor growth that may need additional nutrition support. Infants with an appropriate weight for postconceptional age at discharge should be breast-fed when possible. When formula-fed, such infants should be fed regular infant formula with provision of long-chain polyunsaturated fatty acids. Infants discharged with a subnormal weight for postconceptional age are at increased risk of long-term growth failure, and the human milk they consume should be supplemented, for example, with a human milk fortifier to provide an adequate nutrient supply. If formula-fed, such infants should receive special postdischarge formula with high contents of protein, minerals and trace elements as well as an long-chain polyunsaturated fatty acid supply, at least until a postconceptional age of 40 weeks, but possibly until about 52 weeks postconceptional age. Continued growth monitoring is required to adapt feeding choices to the needs of individual infants and to avoid underfeeding or overfeeding

Does vitamin D intake during infancy promote the development of atopic allergy?
- 2009
-
In: Acta Dermato-Venereologica. - : Medical Journals Sweden AB. - 0001-5555 .- 1651-2057. ; 89:1, s. 28-32
-
Journal article (peer-reviewed)abstract
- The active metabolite of vitamin D, 1,25-(OH)2D3, has immunomodulatory properties in addition to its more established action on bone and calcium metabolism. Recently vitamin D has been proposed as one of several environmental factors responsible for the increase in atopic diseases during the last decades. The objective of this study was to determine whether the estimated dose of dietary vitamin D3 during the first year of life is associated with atopic diseases up to the age of 6 years. In a prospective birth cohort study 123 six-year-old children were investigated for the cumulative incidence of atopic dermatitis, allergic rhinitis or asthma by means of a postal questionnaire. Their vitamin D3 intake during infancy was recorded in a previous study and the relationship between lower or higher vitamin D3 intake and atopic illness later in childhood was assessed. Atopic manifestations were more prevalent in the group with higher intake of vitamin D3. Although small, this study supports previous investigations suggesting a role of vitamin D intake during infancy in the development of atopic allergy later in childhood. If these findings are confirmed in prospective controlled clinical trials, prevention through modified vitamin D3 supplementation in infancy could be discussed to reduce the burden of atopic illnesses.

Serum Vitamin D Depends Less on Latitude Than on Skin Color and Dietary Intake During Early Winter in Northern Europe
- 2016
-
In: Journal of Pediatric Gastroenterology and Nutrition - JPGN. - : Lippincott Williams & Wilkins. - 0277-2116 .- 1536-4801. ; 62:4, s. 643-649

Journal article (peer-reviewed)abstract
- OBJECTIVES: To evaluate if dietary vitamin D intake is adequate for sufficient vitamin D status during early winter in children living in Sweden, irrespective of latitude or skin color.METHODS: As part of a prospective, comparative, two-center intervention study in northern (63°N) and southern (55°N) Sweden, dietary intake, serum 25-hydroxyvitamin D (S-25(OH) D), associated laboratory variables, and socio-demographic data were studied in 5 to 7-year-old children with fair and dark skin in November and December.RESULTS: 206 children with fair/dark skin were included, 44/41 and 64/57 children in northern and southern Sweden, respectively. Dietary vitamin D intake was higher in northern than southern Sweden (p=0.001), irrespective of skin color, partly due to higher consumption of fortified foods, but only met 50-70% of national recommendations (10 μg/day). S-25(OH) D was higher in northern than southern Sweden, in children with fair (67 vs. 59 nmol/L; p < 0.05) and dark skin (56 vs. 42 nmol/L; p < 0.001). S-25(OH) D was lower in dark than fair skinned children at both sites (p < 0.01), and below 50 nmol/L in 40 and 75% of dark-skinned children in northern and southern Sweden, respectively.CONCLUSIONS: Insufficient vitamin D status was common during early winter in children living in Sweden, particularly in those with dark skin. Although, higher dietary vitamin D intake in northern than southern Sweden attenuated the effects of latitude, a northern country of living combined with darker skin and vitamin D intake below recommendations are important risk factors for vitamin D insufficiency.

Effectiveness of vitamin D supplementation in Swedish children may be negatively impacted by BMI and serum fructose
- 2020

In: Journal of Nutritional Biochemistry. - : Elsevier. - 0955-2863 .- 1873-4847. ; 75
-
Journal article (peer-reviewed)abstract
- In regions where sunlight exposure is limited, dietary vitamin D intake becomes important for maintaining status. However, Swedish children have been shown to have deficient or marginal status during the winter months even if the recommended dietary intake is met. Since low vitamin D status has been associated with several disease states, this study investigated the metabolic changes associated with improved vitamin D status due to supplementation.During the 3 winter months, 5-7-year-old children (n=170) in northern (limed, 63 degrees N) and southern (Malmo, 55 degrees N) Sweden were supplemented daily with 2 (placebo), 10 or 25 mu g of vitamin D. BMI-for-age z-scores (BAZ), S-25(OH)D concentrations, insulin concentrations and the serum metabolome were assessed at baseline and follow-up.S-25(OH)D concentrations increased significantly in both supplementation groups (P<.001). Only arginine and isopropanol concentrations exhibited significant associations with improvements in S-25(OH)D. Furthermore, the extent to which S-25(OH)D increased was correlated with a combination of baseline BAZ and the change in serum fructose concentrations from baseline to follow up (P=.012). In particular, the change in S-25(OH)D concentrations was negatively correlated (P=.030) with the change in fructose concentrations for subjects with BAZ >= 0 and consuming at least 20 mu g vitamin D daily. These results suggest that although the metabolic changes associated with improved vitamin D status are small, the effectiveness of dietary supplementation may be influenced by serum fructose concentrations.

Journal article (peer-reviewed)abstract
- Objectives: The aim of this study was to evaluate hypothetical screening strategies in a Swedish celiac disease (CD) mass screening.Methods: Of 10,041 Swedish sixth graders born in 1993 invited to a population-based CD mass screening, 7208 participated. Anti-tissue transglutaminase (tTG) immunoglobulin (Ig) A were analyzed in all children and total serum IgA (s-IgA) in 7161 children. Additional analyses of tTG-IgG, endomysial antibodies (EMA) IgA and IgG, and human leukocyte antigen (HLA) alleles were performed according to a standardized protocol. Children with elevated levels of serological markers were recommended to undergo a small intestinal biopsy to verify diagnosis, and 153 children with CD were thus identified. Sensitivity, specificity, positive predictive values (PPVs) and negative predictive values (NPVs) were calculated and receiver operating characteristic curves were plotted.Results: By lowering the cutoff for tTG-IgA, 17 additional cases of CD were identified at the cost of 32 biopsies. All children with tTG-IgA >50 U/mL (10 times the recommended upper limit of normal) had gluten enteropathy. Area under the receiver operating characteristic curve for tTG-IgA was 0.988. All cases carried HLA-DQ2 or HLA-DQ8, as did 53% of the controls. For different hypothetical screening strategies, sensitivity, specificity, PPV, and NPV ranged between 87.6% and 100%, 99.5% and 99.9%, 79.7% and 89.7%, and 99.7% and 100%, respectively. Efforts to increase sensitivity by lowering tTG-IgA cutoff would result in increased number of small intestinal biopsies and lower PPV. Sequential testing for both EMA and HLA-DQ genotyping would reduce the number of negative small intestinal biopsies.Conclusions: tTG-IgA is a robust marker when used in CD mass screening and its performance can be enhanced by sequential testing for EMA or HLA-DQ genotyping.

A Validation Study of an Interviewer-Administered Short Food Frequency Questionnaire in Assessing Dietary Vitamin D and Calcium Intake in Swedish Children
- 2017

In: Nutrients. - : MDPI AG. - 2072-6643. ; 9:7

Journal article (peer-reviewed)abstract
- Vitamin D and calcium are essential nutrients with a range of biological effects of public health relevance. This study aimed to validate a short food frequency questionnaire (SFFQ) against a three-day food record (3D record), assessing the intake of vitamin D and calcium in Swedish children during wintertime. In a double-blinded, randomized food-based intervention study on the effect of feeding different daily doses of vitamin D supplement to 5-7-year-old children (n = 85), 79 (93%) participants completed SFFQ1 at baseline and SFFQ2 after the intervention, and 72 were informed to fill in a 3D record. The 28 (39%) children who completed the 3D record were included in this validation study. The baseline level of serum-25 hydroxy vitamin D [S-25(OH)D] was used as a biomarker. The correlation between all three instruments were moderate to strong. SFFQ2 and the 3D record correlated moderately to S-25(OH)D. Bland-Altman analysis showed that SFFQ2 overestimated vitamin D intake by on average 0.6 mu g/day, (limits of agreement (LOA) 5.7 and -4.6 mu g/day), whereas the intake of calcium was underestimated by on average 29 mg/day, (LOA 808 and -865 mg/day). Finally, the validity coefficient calculated for vitamin D using the method of triad was high (0.75). In conclusion, this SFFQ, assessed by a dietician, is a valid tool to assess dietary vitamin D and calcium intake in groups of young children.

Low-protein formulas with alpha-lactalbumin-enriched or glycomacropeptide-reduced whey : effects on growth, nutrient intake and protein metabolism during early infancy
- 2023
-
In: Nutrients. - : MDPI. - 2072-6643. ; 15:4
-
Journal article (peer-reviewed)abstract
- Protein intake is higher in formula-fed than in breast-fed infants during infancy, which may lead to an increased risk of being overweight. Applying alpha-lactalbumin (α-lac)-enriched whey or casein glycomacropeptide (CGMP)-reduced whey to infant formula may enable further reduction of formula protein by improving the amino acid profile. Growth, nutrient intake, and protein metabolites were evaluated in a randomized, prospective, double-blinded intervention trial where term infants received standard formula (SF:2.2 g protein/100 kcal; n = 83) or low-protein formulas with α-lac-enriched whey (α-lac-EW;1.75 g protein/100 kcal; n = 82) or CGMP-reduced whey (CGMP-RW;1.76 g protein/100 kcal; n = 80) from 2 to 6 months. Breast-fed infants (BF; n = 83) served as reference. Except between 4 and 6 months, when weight gain did not differ between α-lac-EW and BF (p = 0.16), weight gain was higher in all formula groups compared to BF. Blood urea nitrogen did not differ between low-protein formula groups and BF during intervention, but was lower than in SF. Essential amino acids were similar or higher in α-lac-EW and CGMP-RW compared to BF. Conclusion: Low-protein formulas enriched with α-lac-enriched or CGMP-reduced whey supports adequate growth, with more similar weight gain in α-lac-enriched formula group and BF, and with metabolic profiles closer to that of BF infants.

Journal article (peer-reviewed)abstract
- Objectives: The aim of the study was to evaluate vitamin D status and effects of vitamin D intervention on bone mineral density (BMD) and content (BMC) in children with fair and dark skin in Sweden during winter.Methods: In a 2-center prospective double-blinded randomized intervention study 5- to 7-year-old children (n = 206) with fair and dark skin in Sweden (55 degrees N-63 degrees N) received daily vitamin D supplements of 25 mu g, 10 mu g, or placebo (2 mu g) during 3 winter months. We measured BMD and BMC for total body (TB), total body less head (TBLH), femoral neck (FN), and spine at baseline and 4 months later. Intake of vitamin D and calcium, serum 25-hydroxy vitamin D (S-25 [OH]D), and related parameters were analyzed.Results: Despite lower S-25(OH)D in dark than fair-skinned children, BMD of TB (P = 0.012) and TBLH (P = 0.002) and BMC of TBLH (P = 0.04) were higher at baseline and follow-up in those with dark skin. Delta (Delta) BMD and BMC of TB and TBLH did not differ between intervention and placebo groups, but FN-BMC increased more among dark-skinned children in the 25 mu g (P = 0.038) and 10 mu g (P = 0.027) groups compared to placebo. We found no associations between Delta S-25(OH)D, P-parathyroid hormone, P-alkaline phosphatase, and Delta BMD and BMC, respectively.Conclusions: BMD and BMC remained higher in dark- than fair-skinned children despite lower vitamin D status. Even though no difference in general was found in BMD or BMC after vitamin D intervention, the increase in FN-BMC in dark-skinned children may suggest an influence on bone in those with initially insufficient vitamin D status.

Journal article (peer-reviewed)abstract
- Background: Dark skin and low exposure to sunlight increase the risk of vitamin D insufficiency in children. Objective: The aim of the study was to evaluate the amount of vitamin D needed to ascertain that most children >4 y of age attain sufficient serum25-hydroxyvitamin D [S-25(OH) D; i.e., >= 50 nmol/L] during winter regardless of latitude and skin color. Design: In a longitudinal, double-blind, randomized, food-based intervention study, 5- to 7-y-old children from northern (638 degrees N) and southern (558 degrees N) Sweden with fair (n = 108) and dark (n = 98) skin were included. Children, stratified by skin color by using Fitzpa-trick's definition, were randomly assigned to receive milk-based vitamin D-3 supplements that provided 2 (placebo), 10, or 25 mu g/d during 3 winter months. Results: Mean daily vitamin D intake increased from 6 to 17 mu g and 26 mu g in the intervention groups supplemented with 10 and 25 mu g, respectively. In the intention-to-treat analysis, 90.2% (95% CI: 81.1%, 99.3%) of fair-skinned children randomly assigned to supplementation of 10 mu g/d attained sufficient concentrations, whereas 25 mu g/d was needed in dark-skinned children to reach sufficiency in 95.1% (95% CI: 88.5%, 100%). In children adherent to the study product, 97% (95% CI: 91.3%, 100%) and 87.9% (95% CI: 76.8%, 99%) of fair-and dark-skinned children, respectively, achieved sufficient concentrations if supplemented with 10 mu g/d. By using 95% prediction intervals for 30 and 50 nmol S-25(OH) D/L, intakes of 6 and 20 mu g/d are required in fair-skinned children, whereas 14 and 28 mu g/d are required in children with dark skin. Conclusion: Children with fair and dark skin require vitamin D intakes of 20 and 28 mu g/d, respectively, to maintain S-25(OH) D >= 50 nmol/L, whereas intakes of 6 and 14 mu g/d, respectively, are required to maintain concentrations >= 30 nmol/L during winter.

Does the bile salt stimulated lipase of human milk have a role in the use of the milk long-chain polyunsaturated fatty acids?
- 1993

In: Journal of Pediatric Gastroenterology and Nutrition - Jpgn. - 1536-4801 .- 0277-2116. ; 16:4, s. 426-431

Journal article (peer-reviewed)abstract
- Long-chain polyunsaturated (LCP) fatty acids derived from linoleic (18:2 n-6) and alpha-linolenic (18:3 n-3) acids are considered essential nutrients in preterm infants. The efficiency by which such fatty acids are released as absorbable products from triacylglycerol was explored in vitro using rat chylomicron triacylglycerol as substrate. When incubated with purified human pancreatic colipase-dependent lipase and colipase, arachidonic acid (20:4 n-6) was released less efficiently than linoleic acid from such triacylglycerol. This difference was not seen when purified human milk bile salt-stimulated lipase (BSSL) was incubated with the triacylglycerol substrate, and it was almost abolished when colipase-dependent lipase (with colipase) and BSSL acted simultaneously, as they do in breast-fed infants. There was no difference in arachidonic acid and eicosapentaenoic acid (20:5 n-3) release rates with either colipase-dependent lipase or BSSL, albeit the release was more rapid with the milk enzyme than with colipase-dependent lipase. Again, the most efficient release as absorbable free fatty acids was achieved when the two lipases operated together. The relative resistance to hydrolysis of arachidonic acid and eicosapentaenoic acid by colipase-dependent lipase was best explained by the localization of the first double bond to the delta-5 position of the respective fatty acid. The results obtained suggest that BSSL is of importance for the efficient use of human milk LCP fatty acids.

Journal article (peer-reviewed)abstract
- Background: Observational studies have linked low vitamin D status to unfavorable cardiometabolic risk markers, but double-blinded vitamin D intervention studies in children are scarce. Objectives: The aim was to evaluate the effect of different doses of a vitamin D supplement on cardiometabolic risk markers in young healthy Swedish children with fair and dark skin. Methods: Cardiometabolic risk markers were analyzed as secondary outcomes of a double-blind, randomized, milk-based vitamin D intervention trial conducted during late fall and winter in 2 areas of Sweden (latitude 63°N and 55°N, respectively) in both fair- and dark-skinned 5- to 7-y-old children. During the 3-mo intervention, 206 children were randomly assigned to a daily milk-based vitamin D3 supplement of either 10 or 25 μg or placebo (2 μg; only at 55°N). Anthropometric measures, blood pressure, serum 25-hydroxyvitamin D [25(OH)D], total cholesterol, HDL cholesterol, apoA-I, apoB, and C-reactive protein (CRP) were analyzed and non-HDL cholesterol calculated at baseline and after the intervention. Results: At baseline, serum 25(OH)D was negatively associated with systolic and diastolic blood pressure (β = -0.194; 95% CI: -0.153, -0.013; and β = -0.187; 95% CI: -0.150, -0.011, respectively). At follow-up, there was no statistically significant difference in any of the cardiometabolic markers between groups. Conclusions: We could not confirm any effect of vitamin D supplementation on serum lipids, blood pressure, or CRP in healthy 5- to 7-y-old children.

Bile salt-stimulated lipase and pancreatic lipase-related protein 2 : key enzymes for lipid digestion in the newborn examined using the Caco-2 cell line

-

Journal article (peer-reviewed)abstract
- In rodents, bile salt-stimulated lipase (BSSL) and pancreatic lipase-related protein 2 (PLRP2) are the dominant lipases expressed in the exocrine pancreas in early life, when milk is the main food. The aim of the present study was to evaluate if BSSL and PLRP2 are also key enzymes in neonatal intestinal fat digestion. Using Caco-2 cells as a model for the small intestinal epithelium, purified human enzymes were incubated in the apical chamber with substrates and bile salt concentrations resembling the milieu of the small intestine of newborn infants. BSSL and PLRP2 hydrolyzed triglycerides (TG) to free fatty acids (FA) and glycerol. The cells took up the FA, which were reesterfied to TG. Together, BSSL and PLRP2 have a synergistic effect, increasing cellular uptake 4-fold compared to the sum of each lipase alone. A synergistic effect was also observed with retinyl ester as a substrate. PLRP2 hydrolyzed cholesteryl ester but not as efficiently as BSSL, and the two had an additive rather than synergistic effect. We conclude the key enzymes in intestinal fat digestion are different in newborns than later in life. Further studies are needed to fully understand this difference and its implication for designing optimal neonatal nutrition.

Journal article (peer-reviewed)abstract
- The ontogeny of the immune system and the effect thereon by type of infant feeding is incompletely understood. We analyzed frequencies and composition of immune cells in blood of breastfed (BF) and formula-fed (FF) infants at 1.5, 4, and 6 mo of age. Three formulas with the same protein concentration but with varying levels of alpha-lactalbumin and caseinoglycomacropeptide were compared. Twenty-nine exclusively BF infants served as reference, and 17 infants in each formula group completed the study. Whole blood and PBMCs were analyzed by flow cytometry and immunoflow cytometry, respectively. Leukocyte count of BF infants increased with time due to increased frequency of neutrophils. Lymphocyte count was high at 1.5 mo and was unchanged over time, as were the relative proportions of CD4+ alphabetaT cells, CD8+ alphabetaT cells, B cells, NK cells, and gammadeltaT cells. Most CD45R0+CD3+ cells were HLA-DR- and hence memory cells. Compared with breastfeeding, formula feeding resulted in a significant decrease in proportion of NK cells, but a significant increase in naive CD4+ alphabetaT cells and an elevated CD4-to-CD8 ratio, that is, 3.3 in the combined FF groups compared with 2.6 in the BF group. No significant differences were found between the three groups of FF infants. In conclusion, blood cells of lymphoid lineage did not change significantly in frequencies or composition from 1.5 to 6 mo of age in BF infants. In contrast, FF infants displayed an ongoing maturation of adaptive immunity cells and a delayed recruitment of innate immunity cells as compared with BF infants.
