- Objective/Aim: Growth-differentiation-factor 15 (GDF15) has been suggested to improve or protect beta cell function. During pregnancy, beta cell numbers and function increase to overcome the natural rise in insulin resistance during gestation. In this study, we longitudinally measured serum GDF15 levels during and after pregnancy in women of normal weight (NW) and in women with obesity (OB) and explored associations between GDF15 and changes in beta cell function by homeostatic model assessment (HOMA). Methods: The cohort participants were 38 NW (BMI 22.3 +/- 1.7) and 35 OB (BMI 35.8 +/- 4.2). Blood was sampled and body composition measured at each trimester (T1, T2, and T3) and at 6, 12 and 18 months postpartum. Fasting glucose, insulin and GDF15 were measured, and HOMA for insulin resistance (HOMA-IR) and beta cell function (HOMA-B) determined. Results: GDF15 levels increased significantly each trimester and were similar to 200-fold higher at T3 than in the nonpregnant postpartum state. GDF15 was higher in NW than OB during pregnancy, but was reversed after pregnancy with a significant interaction effect. GDF15 correlated inversely with BMI and fat-free mass at T3. Low GDF15 was associated with lower incidence of nausea and with carrying a male foetus. The pregnancy induced increase in GDF15 associated with increased HOMA-B in OB and with reduced fasting glucose in all women. Conclusion: Large gestational upregulation of GDF15 levels may help increase insulin secretory function to overcome pregnancy-induced insulin resistance.

- PURPOSE: Maternal thyroid function during pregnancy may influence offspring thyroid function, though relations between maternal and child thyroid function are incompletely understood. We sought to characterize relations between maternal, cord and child thyroid hormone concentrations in a population of mother-child pairs with largely normal thyroid function.METHODS: In a prospective birth cohort, we measured thyroid hormone concentrations in 203 mothers at 16 gestational weeks, 273 newborns and 159 children at 3 years among participants in the Health Outcomes and Measures of the Environment (HOME) Study. We used multivariable linear regression to estimate associations of maternal thyroid hormones during pregnancy with cord serum thyroid hormones and also estimated associations of maternal and cord thyroid hormones with child thyroid-stimulating hormone (TSH).RESULTS: Each doubling of maternal TSH was associated with a 16.4% increase of newborn TSH (95% CI: 3.9%, 30.5%), and each doubling of newborn TSH concentrations was associated with a 10.4% increase in child TSH concentrations at 3 years (95% CI: 0.1%, 21.7%). An interquartile range increase in cord FT4 concentrations was associated with an 11.7% decrease in child TSH concentrations at 3 years (95% CI: -20.2%, -2.3%).CONCLUSIONS: We observed relationships between maternal, newborn and child thyroid hormone concentrations in the HOME Study. Our study contributes to understandings of interindividual variability in thyroid function among mother-child pairs, which may inform future efforts to identify risk factors for thyroid disorders or thyroid-related health outcomes.

- Glucocorticoids (GCs) are a cornerstone in treating various common and uncommon diseases. The aim of this study was to estimate the prevalence of GC use in terms of doses associated with risk of tertiary adrenal insufficiency in adults and children, and treatment indications.This was a retrospective cohort study. Information on dispensed prescriptions was obtained from the Swedish Prescribed Drug Register. Patients with prescriptions of prednisolone (or equivalent dose of other GCs) ≥5 mg daily for ≥21 days between 2007-2014 were included. Information on concurrent diseases was obtained from the Swedish National Patient Register and the Västra Götaland Regional Healthcare Database.Of 1,585,335 inhabitants in Västra Götaland County, 223,211 were included in the study (women 55.6%). Mean age was 48 ± 24 years. Period prevalence of oral GC use during the 8-year study period was 14.1%. The highest prevalence (27.4%) was in men aged 80-89 years and lowest (7.5%) in men 10-19 years of age. The period prevalence in children 0-9 years of age was 10.6%. COPD and asthma were the most common indications for treatment (17.2%) followed by allergy (12.5%), and malignant neoplasms (11.5%). Allergy was the most frequent indication (20.5%) in children and adolescents.Between 2007-2014, every seventh inhabitant in western Sweden received a GC prescription at doses associated with risk of developing tertiary adrenal insufficiency. These findings illustrate the importance of awareness of the potential development of tertiary adrenal insufficiency in both pediatric and adult patients.

- Objective To explore health-related quality of life (HRQoL) among subjects with hypothyroidism compared to subjects without hypothyroidism in the general population. HRQoL is important in clinical practice. Hypothyroidism is prevalent, mainly found in women, and increasing with age. Design Cohort study of random population sample. Patients Women and men, n = 414 (39-78 years) from the WHO MONICA project, Gothenburg, Sweden, participated. Hypothyroidism was defined as subjects having levothyroxine supplementation or serum thyroid-stimulating hormone (S-TSH) >4.2 mU/L. Measurements Health-related quality of life was measured with Psychological General Well-Being Index (PGWB), Nottingham Health Profile (NHP), Short Form 36 Health Survey (SF-36) and a single item self-rated health scale (0-100), and stress was rated 1-6. The results were adjusted for age, sex and comorbidity using analysis of covariance (ANCOVA). Results Hypothyroidism was found in 70 subjects (17%). They scored worse HRQoL than controls regarding Sleep (p < .001), Social isolation (p = .01) and Total NHP (p < .05), and had more medication in general 2.7 +/- 2.5 vs. 1.8 +/- 2.1, p < .05. Subjects with levothyroxine (n = 40) showed similar results as the total hypothyroid group. Subjects unaware of their newly detected elevated STSH (n = 30) showed lower HRQoL in Sleep (p < .01) and Pain (p < .05) in NHP. HRQoL was similar in subjects with and without positive thyroperoxidase antibodies (TPO-Ab) either in those with hypothyroidism (44% TPO-Ab) or controls (9% TPO-Ab). Conclusion Men and women with hypothyroidism in the general population reported having more issues with Sleep and Social isolation than those without hypothyroidism irrespective of TPO-Ab. Scores were similar in all of the other HRQoL domains measuredAQ5.

- Context: White matter lesions (WML) are caused by obstruction of small cerebral vessels associated with stroke risk. Craniopharyngioma (CP) patients suffer from increased cerebrovascular mortality. Objective: To investigate the effect of reduced HT volume and cranial radiotherapy (CRT) on WML in childhood-onset CP patients. Design: A cross-sectional study of 41 patients (24 women) surgically treated childhood-onset CP in comparison to controls. Setting: The South Medical Region of Sweden (2.5 million inhabitants). Methods: With magnetic resonance imaging (MRI), we analysed qualitative measurement of WML based on the visual rating scale of Fazekas and quantitative automated segmentation of WML lesion. Also, measurement HT volume and of cardiovascular risk factors were analysed. Results: Patients had a significant increase in WML volume (mL) (P =.001) compared to controls. Treatment with cranial radiotherapy (CRT) vs no CRT was associated with increased WML volume (P =.02) as well as higher Fazekas score (P =.001). WML volume increased with years after CRT (r = 0.39; P =.02), even after adjustment for fat mass and age. A reduced HT volume was associated with increased WML volume (r = −0.61, P <.001) and explained 26% of the variation (r2 = 0.26). Altogether, 47% of the WML volume was explained by age at investigation, HT volume and CRT. Patients with more WML also had higher cardiovascular risk. Conclusions: CRT may be associated directly with increased WML volume or indirectly with reduced HT volume associated with higher cardiovascular risk. Risk factors should be carefully monitored in these patients.

- BACKGROUND AND OBJECTIVE: Kabuki syndrome (KS), caused by pathogenic variants in KMT2D or KDM6A, is associated with hyperinsulinemic hypoglycemia (HH) in 0.3-4% of patients. We characterized the clinical, biochemical and molecular data of children with KS and HH compared to children with KS without HH in a multicenter meta-analysis.METHODS: Data of seven new and 17 already published children with KS and HH were compared to 373 recently published KS patients without HH regarding molecular and clinical characteristics.RESULTS: Seven new patients were identified with seven different pathogenic variants in KDM6A (n=4) or KMT2D (n=3). All presented with HH on the first day of life and were responsive to diazoxide. KS was diagnosed between 9 months and 14 years of age. In the meta-analysis 24 KS patients with HH had a significantly higher frequency of variants in KDM6A compared to 373 KS patients without HH (50% vs. 11.5%, p<0.001), and KDM6A-KS was more likely to be associated with HH than KMT2D-KS (21.8% vs. 3.5%, p<0.001). Sex distribution and other phenotypic features did not differ between KS with and without HH.CONCLUSION: The higher incidence of HH in KDM6A-KS compared to KMT2D-KS indicates that KDM6A loss of function variants predispose more specifically to beta cell dysfunction compared to KMT2D variants. As difficulties to assign syndromic characteristics to KS in early infancy often lead to delayed diagnosis, genetic testing for KS should be considered in children with HH, especially in the presence of other extrapancreatic/syndromic features.

Forskningsöversikt (refereegranskat)abstract
- Gut microbiome transfer (GMT; also referred to as faecal microbiota transplantation or FMT) has been propelled from fringe therapy to mainstream science as a highly effective treatment for recurrent Clostridioides difficile infection. As a result, there has been great interest in the potential efficacy and safety of GMT in treating other medical conditions, for example inflammatory bowel disease, and more recently as a novel therapy for obesity and metabolic diseases. For these chronic conditions, the results from clinical trials have been mixed. Further, specifically in obesity and metabolic diseases, there are limited available data, with only a few published studies with a small number of participants and short duration of follow-up. Therefore, this review aims to explore the human, microbial and formulation factors that may affect the success of GMT. This includes various aspects in the preparation and administration of GMT, such as stool processing, modes of delivery, pretreatment with antibiotics and/or bowel lavage, frequency of GMT and possible use of precision bacteriotherapy. In addition, we examine the potential use of GMT in obesity, type 2 diabetes and metabolic diseases based on current available literature, highlighting some recent advances in GMT research in this area, as well as potential adverse effects after GMT therapy.
