AbstractMany common diseases show wide phenotypic variation. We present a statistical method for determining whether phenotypically defined subgroups of disease cases represent different genetic architectures, in which disease-associated variants have different effect sizes in the two subgroups. Our method models the genome-wide distributions of genetic association statistics with mixture Gaussians. We apply a global test without requiring explicit identification of disease-associated variants, thus maximising power in comparison to a standard variant by variant subgroup analysis. Where evidence for genetic subgrouping is found, we present methods for post-hoc identification of the contributing genetic variants.We demonstrate the method on a range of simulated and test datasets where expected results are already known. We investigate subgroups of type 1 diabetes (T1D) cases defined by autoantibody positivity, establishing evidence for differential genetic architecture with thyroid peroxidase antibody positivity, driven generally by variants in known T1D associated regions.

Adverse Pregnancy

<b><i>Background:</i></b> Gestation complications have a recurrence risk and could predispose to each other in the next pregnancy. We aimed to evaluate the relationship between a history of adverse pregnancy and maternal-fetal outcomes in subsequent pregnancy in patients with Immunoglobulin A nephropathy (IgAN). <b><i>Methods:</i></b> A retrospective cohort study from a Chinese single center was conducted. Pregnant women with biopsy-proven primary IgAN and aged ≥18 years were enrolled and divided into the 2 groups by a history of adverse pregnancy. The primary outcome was adverse pregnancy outcome, which included maternal-fetal outcomes. Logistical regression model was used to evaluate the association of a history of adverse pregnancy with subsequent adverse maternal and fetal outcomes. <b><i>Results:</i></b> Ninety-one women with 100 pregnancies were included, of which 54 (54%) pregnancies had a history of adverse pregnancy. IgAN patients with adverse pregnancy history had more composite maternal outcomes (70.4% vs. 45.7%, <i>p</i> = 0.012), while there was no difference in the composite adverse fetal outcomes between the 2 groups (55.6% vs. 45.7%). IgAN patients with a history of adverse pregnancy were associated with an increased risk of subsequent adverse maternal outcomes (adjusted odds ratio [OR], 2.64; 95% CI, 1.07–6.47). Similar results were shown in those with baseline serum albumin &#x3c;3.5 g/dL, 24 h proteinuria ≥1 g/day, and a history of hypertension. There was no association between a history of adverse pregnancy and subsequent adverse fetal outcomes in IgAN patients (adjusted OR, 1.56; 95% CI, 0.63–3.87). <b><i>Conclusion:</i></b> A history of adverse pregnancy was associated with an increased risk of subsequent adverse maternal outcomes, but not for adverse fetal outcomes in IgAN patients.

Thyroid hormone (TH) affects many metabolic processes such as promoting oxidation of sugar, fat, and protein in many tissues. Thyroid dysfunction is associated with metabolic disorders. The newly discovered adipocyte- and hepatocyte-derived cytokine, betatrophin, has been reported to be involved in metabolic diseases, but its influence on thyroid dysfunction is uncertain. Therefore, the present study aims to evaluate circulating betatrophin levels in subjects with different thyroid function status and to predict the factors associated with betatrophin levels, especially whether thyroid stimulating hormone (TSH), TH, or thyroid autoantibodies are associated with betatrophin levels. In the study, serum betatrophin was measured in the subjects grouped as overt hypothyroidism (OH), subclinical hypothyroidism (SCH), euthyroid with isolated thyroid peroxidase antibody positivity (isolated Ab), and healthy control (HC), according to their thyroid functions. From our results, we found that betatrophin may be associated with thyroid insufficiency but not thyroid autoimmunity. Thus, when interpreting the results of betatrophin, thyroid functions should also be taken into consideration.

Aim.The aim of the study was to study the relation of vitiligo with demographic data like age, sex, and duration and determine the prevalence of thyroid autoimmunity in vitiligo patients.Materials and Methods.This study was a cross sectional study consisting of 100 patients clinically diagnosed (old and new) as having vitiligo irrespective of age or sex. Patients with known thyroid disease on supplementation therapy, or who had undergone thyroid surgery, those on antithyroid medication, patients with other causes of leukoderma, and cases who do not provide informed consent were excluded from the study. Serum TSH and anti-TPO antibodies were measured in all the patients.Results.The prevalence of anti-TPO antibody positivity was found to be 28%.Conclusion.According to our study, none of our vitiligo patients had symptoms or signs of thyroid disease at the time of presentation but, on biochemical evaluation, anti-TPO antibodies were found in a considerable number of patients. Hence, we recommend screening of these patients with thyroid antibodies.
