Analysis of IL-1β, TGF-β, IL-5, ACE, PTPN22 gene polymorphisms, and gene expression levels in Turkish children with IgA vasculitis.

Objective: Immunoglobulin-A vasculitis (IgAV) is an inflammatory disease that affects small blood vessels. This study was performed to identify an association between protein tyrosine phosphatase non-receptor type 22 (PTPN22) + 788G > A (rs33996649), transforming growth factor-beta (TGF-β) -509C > T (rs18004069), interleukin 1-beta (IL-1β) -511C > T (rs16944), interleukin 5 (IL-5) -746C/T (rs2069812), and angiotensin-converting enzyme (ACE) I/D (rs4646994) gene polymorphisms, susceptibility to IgAV, as well as the mRNA levels of IL-1β, IL-1β, and TGF-β.

Method: A total of 53 patients with IgAV and 50 healthy controls were enrolled.

An Extraordinary Case of Autoimmune Polyendocrinopathy-Candidiasis-Ectodermal Dystrophy (APECED) Syndrome Misdiagnosed as Juvenile Idiopathic Arthritis on Admission.

Background: APECED is a syndrome characterized by autoimmune polyendocrinopathy, candidiasis, and ectodermal dystrophy. The most observed clinical findings are chronic mucocutaneous candidiasis, hypoparathyroidism, and autoimmune adrenal insufficiency. .

An analysis of children with brucellosis associated with haemophagocytic lymphohistiocytosis.

This retrospective study included seven paediatric cases aged from 4 to 14 (10.2±3.4) years with pathologically proved haemophagocytic lymphohistiocytosis from a single institution during 2009 and 2013.
