Context Primary ovarian insufficiency (POI) is defined by menopause before 40 years of age. POI prevalence is higher among women with autoimmune Addison’s disease (AAD) than in the general population, but their clinical characteristics are insufficiently studied. Objective To assess the prevalence of POI in a large cohort of AAD women and describe clinical, immunological, and genetic characteristics. Design and settings An observational population-based cohort study of The Norwegian National Addison Registry. The Norwegian Prescription Database (NorPD) was used to assess prescription of menopausal hormone replacement therapy (HRT). Patients A total of 458 women with AAD were studied. Main outcome measures The primary outcome was prevalence of POI. Secondary outcomes were clinical characteristics, autoantibodies, and genome-wide single nucleotide polymorphism (SNP) variation. Results The prevalence of POI was 10.2% (47/458) and one third developed POI before 30 years of age. POI preceded or coincided with AAD diagnosis in more than half of the women. The prevalence of concomitant autoimmune diseases was 72%, and AAD women with POI had more autoantibodies than AAD women without (≥2 autoantibodies in 78% vs 25%). Autoantibodies against side-chain cleavage enzyme (SCC) had the highest accuracy with a negative predictive value for POI of 96%. HRT use was high compared to the age adjusted normal population (11.3 % vs 0.7%). Conclusion One in ten AAD women have POI. Autoantibodies against SCC are the most specific marker for autoimmune POI. We recommend testing AAD women < 40 years with menstrual disturbances or fertility concerns for autoantibodies against SCC.
Context Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED or APS-1) has a severe, unpredictable course. Autoimmunity and disease components may affect fertility and predispose to maternal and fetal complications, but pregnancy outcomes remain unknown. Objective To assess fetal and maternal outcomes and course of clinical APECED manifestations during pregnancy in women with APECED. Design and setting A multicenter registry-based study including five national patient cohorts. Patients 321 females with APECED. Main outcome measure Number of pregnancies, miscarriages, and deliveries. Results Forty-three patients had altogether 83 pregnancies at median age of 27 years (range, 17–39). Sixty (72%) pregnancies led to a delivery, including two stillbirths (2.4%) and five (7.1%) preterm livebirths. Miscarriages, induced abortions, and ectopic pregnancies were observed in 14 (17%), eight (10%), and one (1.2%) of pregnancies, respectively. Ovum donation resulted in five (6.0%) pregnancies. High maternal age, premature ovarian insufficiency, primary adrenal insufficiency, or hypoparathyroidism did not associate with miscarriages. Women with livebirth had on average four APECED manifestations (range 0–10); 78% had hypoparathyroidism and 36% had primary adrenal insufficiency. APECED manifestations remained mostly stable during pregnancy, but in one case development of primary adrenal insufficiency led to adrenal crisis and stillbirth. Birth weights were normal in >80% and apart from one neonatal death of a preterm baby, no serious perinatal complications occurred. Conclusions Outcome of pregnancy in women with APECED was generally favorable. However, APECED warrants careful maternal multidisciplinary follow-up from pre-conceptual care until puerperium.
HighlightsWe screened for signs of neuropathy in a diabetes population in Zanzibar.Nerve conduction study by NC-stat DPNCheck found neuropathy in 45%.Monofilament results suggestive of neuropathy in 61%.Compared to nerve conduction study, monofilament had a 59% specificity.Hyperglycaemia and hypertension are highly prevalent risk factors in this population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
