- BACKGROUND & AIMS: Inflammatory bowel disease (IBD) is linked to reduced female fertility, but it is unclear how fertility rates vary by histological disease activity.METHODS: Nationwide IBD cohort of Swedish women aged 15-44 years. We examined fertility rates during periods with vs. without histological inflammation (n=21,046; follow-up: 1990-2016) and during periods with vs. without clinical activity (IBD-related hospitalization, surgery, or treatment escalation) (n=24,995; follow-up: 2006-2020). Accounting for socio-demographics and comorbidities, we used Poisson regression to estimate adjusted fertility rate ratios (aFRRs) for live-births conceived during 12-month-periods of histological inflammation (vs. histological remission) and 3-month-periods of clinically active IBD (vs. quiescent IBD).RESULTS: During periods with vs. without histological inflammation, there were 6.35 (95%CI=5.98-6.73) and 7.09 (95%CI=6.48-7.70) live-births conceived per 100 person-years of follow-up, respectively, or one fewer child per fourteen women with 10 years of histological inflammation (aFRR=0.90; 95%CI=0.81-1.00). In women with histological inflammation fertility was similarly reduced in ulcerative colitis (UC, aFRR=0.89 [95%CI=0.78-1.02]) and Crohn's disease (CD, aFRR=0.86 [95%CI=0.72-1.04]). Clinical IBD activity was associated with an aFRR of 0.76 (95%CI=0.72-0.79) or one fewer child per six women with 10 years of clinical activity. Fertility was reduced in clinically active UC (aFRR=0.75 [95%CI=0.70-0.81]) and CD (aFRR=0.76 [95%CI=0.70-0.82]). Finally, also among women with clinically quiescent IBD, histological inflammation (vs. histological remission) was associated with reduced fertility (aFRR=0.85 [95%CI=0.73-0.98]).CONCLUSIONS: An association between histological and clinical activity and reduced female fertility in CD and UC was found. Notably, histological inflammation was linked to reduced fertility also in women with clinically quiescent IBD.

- Background: The etiology of recurrent abdominal pain of functional origin (AP) is largely unknown. Antibiotic treatment influences the intestinal microbiota, and a few studies have indicated an increased risk of AP in adults after antibiotic treatment. Corresponding data in children are lacking. The aim of this study was to explore the association between antibiotic treatment during childhood and AP at 12years.Methods: Two thousand seven hundred and thirty-two children from a Swedish, population-based birth cohort. Parents reported antibiotic use for the children between birth and 2years. Antibiotic use between 9 and 12years was collected from the Swedish Prescribed Drug Register. The children answered questionnaires regarding AP at age 12. We used logistic regression to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for AP at 12years as a function of antibiotic use.Key Results: Antibiotic treatment between 9 and 12years was not associated with AP at 12. Children who had received 3 courses, or broad-spectrum antibiotics between 9 and 12years had an increased risk of AP at 12, but these associations failed to reach statistical significance. Antibiotic treatment during both the first and the second year of life increased the risk of AP in girls at 12 (OR 1.65; 95% CI: 1.09-2.49), but not in boys or the whole cohort.Conclusions & Inferences: Antibiotic treatment does not seem to be a major risk factor for AP at 12years. However, we cannot exclude that repeated courses, especially to infant girls, or use of broad-spectrum antibiotics between 9 and 12years may be associated with an increased risk of AP.

- BACKGROUND & AIMS: Few studies have explored the link between childhood celiac disease and long-term psychiatric comorbidities. We performed a population-based cohort study of associations between childhood celiac disease and psychiatric disorders and investigated whether risk persists into adulthood.METHODS: We performed a nationwide study in Sweden using data from the ESPRESSO cohort. In this cohort, 19,186 children with a diagnosis of biopsy-verified celiac disease from 1973 through 2016 were identified from Sweden's 28 pathology departments. Each patient was matched with as many as 5 reference children (controls, n=94,249). Data on psychiatric disorders were obtained from the patient register. We used Cox proportional modeling to estimate hazard ratios (HRs).RESULTS: During a median follow-up time of 12.3 years, 3174 children (16.5%) with celiac disease received a new diagnosis of a psychiatric disorder, compared with 13,286 controls (14.1%). Corresponding incidence rates were 12.2 per 1000 person-years (95% Cl, 11.8-12.7) vs 10.3 per 1000 person-years (95% Cl, 10.2-10.5). Childhood celiac disease was associated with a 19% increase in risk of any psychiatric disorder (95% Cl, 1.14-1.23); the increase in risk was observed in all childhood age groups. The highest HRs were seen in the first year after celiac diagnosis (HR, 1.70; 95% Cl, 1.41-2.05). The risk increase persisted into adulthood (older than 18 years: HR, 1.11; 95% Cl, 1.04-1.17). We found increased risks of mood disorders (HR, 1.20; 95% CI, 1.12-1.28), anxiety disorders (HR, 1.12; 95% CI, 1.06-1.19), eating disorders (HR, 1.34; 95% CI, 1.18-1.51), attention deficit hyperactivity disorder (HR, 1.29; 95% CI, 1.20-1.39), and autism spectrum disorder (HR, 1.47; 95% CI, 1.32-1.64). We found no statistically significant risk increase for psychotic disorders, psychoactive substance misuse, behavioral disorders, personality disorders, suicide attempt, or suicide. Celiac disease was also linked to an increased use of psychiatric drugs (HR, 1.34; 95% CI, 1.24-1.43). A conditional logistic regression found that psychiatric disorders were also more common prior to diagnosis of celiac disease (odds ratio, 1.56; 95% Cl, 1.39-1.76).CONCLUSIONS: Childhood celiac disease is associated with increased risk of subsequent psychiatric disorders, which persists into adulthood. Mental health surveillance should be integral in the care of celiac disease.

- To assess the association and familial coaggregation between early-onset type 2 diabetes (diagnosed before age 45 years) and mood, anxiety, and stress-related disorders and estimate the contribution of genetic and environmental factors to their co-occurrence.This population-based cohort study included individuals born in Sweden during 1968-1998, from whom pairs of full siblings, half-siblings, and cousins were identified. Information on diagnoses of early-onset type 2 diabetes and mood (including unipolar depression and bipolar disorder), anxiety, and stress-related disorders was obtained from the National Patient Register. Logistic and Cox regression models were used to assess the phenotypic association and familial coaggregation between type 2 diabetes and psychiatric disorders. Quantitative genetic modeling was conducted in full and maternal half-sibling pairs to estimate the relative contributions of genetic and environmental factors to the association.Among a total of 3,061,192 individuals, 7,896 (0.3%) were diagnosed with early-onset type 2 diabetes. These individuals had higher risks of any diagnosis (odds ratio [OR] 3.62 [95% CI 3.44, 3.80]) and specific diagnosis of unipolar depression (3.97 [3.75, 4.22]), bipolar disorder (4.17 [3.68, 4.73]), anxiety (3.76 [3.54, 3.99]), and stress-related disorders (3.35 [3.11, 3.61]). Relatives of individuals with early-onset type 2 diabetes also had higher overall risks of the examined psychiatric disorders (ORs 1.03-1.57). These associations are largely explained by genetic factors (51-78%), with the rest explained by nonshared environmental factors.Our findings highlight the burden of mood, anxiety, and stress-related disorders in early-onset type 2 diabetes and demonstrate that shared familial liability may contribute to their co-occurrence, suggesting that in the future research investigators should aim to identify shared risk factors and ultimately refine preventive and intervention strategies.

Forskningsöversikt (refereegranskat)abstract
- It is increasingly recognized that children with asthma are at a higher risk of other non-allergic concurrent diseases than the non-asthma population. A plethora of recent research has reported on these comorbidities and progress has been made in understanding the mechanisms for comorbidity. The goal of this review was to assess the most recent evidence (2016-2021) on the extent of common comorbidities (obesity, depression and anxiety, neurodevelopmental disorders, sleep disorders and autoimmune diseases) and the latest mechanistic research, highlighting knowledge gaps requiring further investigation. We found that the majority of recent studies from around the world demonstrate that children with asthma are at an increased risk of having at least one of the studied comorbidities. A range of potential mechanisms were identified including common early life risk factors, common genetic factors, causal relationships, asthma medication and embryologic origins. Studies varied in their selection of population, asthma definition and outcome definitions. Next, steps in future studies should include using objective measures of asthma, such as lung function and immunological data, as well as investigating asthma phenotypes and endotypes. Larger complex genetic analyses are needed, including genome-wide association studies, gene expression-functional as well as pathway analyses or Mendelian randomization techniques; and identification of gene-environment interactions, such as epi-genetic studies or twin analyses, including omics and early life exposure data. Importantly, research should have relevance to clinical and public health translation including clinical practice, asthma management guidelines and intervention studies aimed at reducing comorbidities.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Celiac disease (CD) is associated with increased mortality, in part due to cancer. Most studies investigating this cancer risk involved patients diagnosed before widespread increases in CD diagnosis rates and access to gluten-free food. We performed a population-based study of the risk of cancer in CD.METHODS: We identified all patients in Sweden with CD as defined as duodenal villus atrophy, using the ESPRESSO cohort. Each patient was matched to ≤5 controls by age, sex, and county. We used stratified Cox proportional-hazards model, following patients from diagnosis until first cancer, or by December 31, 2016.RESULTS: Among 47,241 patients with CD, 30,080 (64%) were diagnosed since 2000. After a median follow-up of 11.5 years, the incidence of cancer was 6.5 and 5.7 per 1000 person-years in CD patients and controls, respectively. The overall risk of cancer was increased (hazard ratio[HR] 1.11; 95%CI 1.07-1.15), but was only significantly elevated in the first year after CD diagnosis (HR 2.47; 95%CI 2.22-2.74), and not subsequently (HR 1.01; 95%CI 0.97-1.05), though the risks of hematologic, lymphoproliferative, hepatobiliary, and pancreas cancers persisted. The overall risk was highest in those diagnosed with CD after age 60 years (HR 1.22; 95%CI 1.16-1.29) and was not increased in those diagnosed before age 40. The cancer risk was similar among those diagnosed with CD before or after the year 2000.CONCLUSIONS: There is an increased risk of cancer in CD, even in recent years, but this risk increase is confined to those diagnosed with CD after age 40, and is primarily present within the first year of diagnosis.

Smoking, use of moist snuff and risk of celiac disease : a prospective study
- 2014
-
Ingår i: BMC Gastroenterology. - : BioMed Central. - 1471-230X. ; 14
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Smoking status has been linked to several chronic inflammatory conditions but earlier research on smoking and celiac disease (CD) is contradictive. There are little data on moist snuff use and CD. The purpose of this study was to investigate the association between smoking, moist snuff use and later CD.Methods: We identified individuals with biopsy-verified CD (villous atrophy, histopathology stage Marsh III) through biopsy-reports from Sweden's 28 pathology departments. Data on smoking and moist snuff were collected from the Swedish construction worker database "Bygghalsan" that includes preventive health care check-up data. Through poisson regression we calculated relative risks (RRs) for later CD according to smoking status (n = 305,722), and moist snuff status (n = 199,200) adjusting for age, sex and decade.Results: During follow-up 488 individuals with smoking data, and 310 with moist snuff data had a diagnosis of CD. The risk of CD was independent of smoking status with all RRs being statistically insignificant and ranging between 0.9 and 1.0. Compared to non-smokers, neither current smokers (RR = 0.93; 95% CI = 0.76-1.14) nor ex-smokers (RR = 0.98; 95% CI = 0.75-1.28) were at increased or decreased risk of CD. Risk estimates were similar in moderate smokers (RR = 0.92; 0.72-1.16) and heavy smokers (RR = 0.95; 0.74-1.24), and did not change when we examined the risk more than ten years after health examination (RR-moderate: 0.90; and RR-heavy: 0.95; both p > 0.05). Moist snuff use was not associated with later CD (RR = 1.00; 0.78-1.28), or with CD after more than ten years of follow-up (RR = 1.05; 0.80-1.38).Conclusions: We found no association between smoking, moist snuff use and future CD.

- Background: TNF inhibitors (TNFi) have been shown to reduce the need for surgery in Crohn's disease, but few studies have examined their effect beyond the first year of treatment.Aim: To conduct a register-based observational cohort study in Sweden 2006-2014 to investigate the risk of bowel resection in bowel surgery naive TNFi-treated Crohn's disease patients and whether patients on TNFi >= 12 months are less likely to undergo bowel resection than patients discontinuing treatment before 12 months.Methods: We identified all individuals in Sweden with Crohn's disease through the Swedish National Patient Register 1987-2014 and evaluated the incidence of bowel resection after first ever dispensation of adalimumab or infliximab from 2006 and up to 7 years follow-up.Results: We identified 1856 Crohn's disease patients who had received TNFi. Among these patients, 90% treatment retention was observed at 6 months after start of TNFi and 65% remained on the drug after 12 months. The cumulative rates of surgery in Crohn's disease patients exposed to TNFi years 1-7 were 7%, 13%, 17%, 20%, 23%, 25% and 28%. Rates of bowel resection were similar between patients with TNFi survival < 12 months and >= 12 months respectively (P=.27). No predictors (eg, sex, age, extension or duration of disease) for bowel resection were identified.Conclusions: The risk of bowel resection after start of anti-TNF treatment is higher in regular health care than in published RCTs. Patients on sustained TNFi treatment beyond 12 months have bowel resection rates similar to those who discontinue TNFi treatment earlier.

- INTRODUCTION: Celiac disease (CD) affects 1% of the population. Its effect on healthcare cost, however, is barely understood. We estimated healthcare use and cost in CD, including their temporal relationship to diagnosis.METHODS: Through biopsy reports from Sweden's 28 pathology departments, we identified 40,951 prevalent patients with CD (villous atrophy) as of January 1, 2015, and 15,086 incident patients with CD diagnosed in 2008-2015, including 2,663 who underwent a follow-up biopsy to document mucosal healing. Each patient was compared with age- and sex-matched general population comparators (n = 187,542). Using nationwide health registers, we retrieved data on all inpatient and nonprimary outpatient care, prescribed diets, and drugs.RESULTS: Compared with comparators, healthcare costs in 2015 were, on average, $1,075 (95% confidence interval, $864-1,278) higher in prevalent patients with CD aged <18 years, $715 ($632-803) in ages 18-64 years, and $1,010 ($799-1,230) in ages ≥65 years. Half of all costs were attributed to 5% of the prevalent patients. Annual healthcare costs were $391 higher 5 years before diagnosis and increased until 1 year after diagnosis; costs then declined but remained 75% higher than those of comparators 5 years postdiagnosis (annual difference = $1,044). Although hospitalizations, nonprimary outpatient visits, and medication use were all more common with CD, excess costs were largely unrelated to the prescription of gluten-free staples and follow-up visits for CD. Mucosal healing in CD did not reduce the healthcare costs.DISCUSSION: The use and costs of health care are increased in CD, not only before, but for years after diagnosis. Mucosal healing does not seem to lower the healthcare costs.

- BackgroundAllergy and immune dysregulation may have a role in the pathophysiology of recurrent abdominal pain of functional origin, but previous studies of allergy-related diseases and abdominal pain have contradictory results. AimTo examine the association between allergy-related diseases or sensitisation during childhood and abdominal pain at age 12years. MethodsIn this birth cohort study of 4089 children, parents answered questionnaires regarding asthma, allergic rhinitis, eczema and food hypersensitivity (allergy-related diseases') at ages 0,1,2,4,8 and 12years. Blood for analyses of allergen-specific IgE was sampled at 4 and 8years. At 12years, the children answered questions regarding abdominal pain. Children with coeliac disease or inflammatory bowel disease were excluded. Associations were examined using multivariable logistic regression. ResultsAmong 2610 children with complete follow-up, 9% (n=237) reported abdominal pain at 12years. All allergy-related diseases were associated with concurrent abdominal pain at 12years and the risk increased with increasing number of allergy-related diseases (P for trend <0.001). Asthma at 1 and 2years and food hypersensitivity at 8years were significantly associated with abdominal pain at 12years. There was an increased risk of abdominal pain at 12years in children sensitised to food allergens at 4 or 8years, but in stratified analyses, this was confined to children whose parents had not reported food hypersensitivity at time of sensitisation. ConclusionAllergy-related diseases as well as sensitisation to food allergens were associated with an elevated risk of abdominal pain, and the risk increased with the number of allergy-related diseases.
