Article Abstract
Loss-of-function variants in the gene have been identified as the strongest cause of susceptibility to atopic dermatitis (AD) in Europeans and Asians. However, very little is known about the genetic etiology behind AD in African populations, where the prevalence of AD is notably high. We sought to investigate the genetic origins of AD by performing whole-genome sequencing in an Ethiopian family with 12 individuals and several affected in different generations. We identified 2 variants within (p.D13Y) and (p.A918S) genes cosegregating with AD in the affected individuals. Further genotyping analyses in both Ethiopian and Swedish AD cases and controls revealed a significant association with the variant (p.D13Y, < .0013) only in the Ethiopian cohort. However, the variant (p.A918S) did not show any association in our Ethiopian cohort. Instead, 2 previously recognized variants (p.A849V, < .0085 and p.G908R, < .0036) were significantly associated with AD in our Ethiopian cohort. Our study indicates that the and genes might be important in the etiology of AD in Ethiopians. Additional genetic and functional studies are needed to confirm the role of these genes and the associated variants into the development of AD.

Purpose: Drug-induced liver injury (DILI) is a relevant adverse event of tuberculosis treatment (TBT) especially in sub-Saharan Africa, but data remains limited. Genetic hepatic transport proteins polymorphisms (HTPP) are potential contributors. This study aimed to assess frequency and timing of DILI, identify risk factors, and explore the association of HTPP with DILI risk in Ethiopian TBT-patients.

Nonalcoholic fatty liver disease (NAFLD) is an emerging global health concern that commonly occurs in patients with Type 2 diabetes mellitus (T2DM). However, there is limited literature on the epidemiology of NAFLD among adults with T2DM in Ethiopia. Therefore, this study is aimed at assessing the prevalence of NAFLD and its associated factors in patients with T2DM attending Yekatit 12 Hospital Medical College in Addis Ababa, Ethiopia.

Background: Pneumonia is a leading cause of morbidity and mortality in children under five years of age. In 2012, the World Health Organization revised its guidelines for managing childhood pneumonia and recommended oral amoxicillin for the outpatient treatment of chest indrawing pneumonia in children aged 2-59 months. While the Ethiopian government subsequently adopted these revised pneumonia guidelines, the level of their implementation and of the related treatment outcomes remains less known.

Background: Women´s index pregnancy emotional fertility intention was measured by asking the pregnant women how they would felt when they learned about their index pregnancy. Emotional health and couples´ communication are key during pregnancy and child birth with simultaneous minimization of reproductive coercion. Emotional fertility intention is critical for healthy and spaced pregnancies, as well as for better maternal and newborns outcomes.
