Clinical and genetic analysis of patients with X-linked hyper-IgM syndrome.

To the Editor : Hyper-immunoglobulin M (IgM) syndromes are characterized by the presence of recurrent infections, low levels of IgG and IgA, and normal to high levels of IgM. The X-linked hyper-IgM (X-HIGM) syndrome is the most frequently observed subtype of hyperIgM syndromes (65–70%) and results from defects in the CD40L gene, which encodes for the CD40 ligand (CD154) (1–3). In this study, a ...

Clinical Features and Genetic Analysis of 20 Chinese Patients with X-Linked Hyper-IgM Syndrome

X-linked hyper-IgM syndrome (XHIGM) is one type of primary immunodeficiency diseases, resulting from defects in the CD40 ligand/CD40 signaling pathways. We retrospectively analyzed the clinical and molecular features of 20 Chinese patients diagnosed and followed up in hospitals affiliated to Shanghai Jiao Tong University School of Medicine from 1999 to 2013. The median onset age of these patien...

X-linked hyper-IgM syndrome with CD40LG mutation: two case reports and literature review in Taiwanese patients.

Hyper-IgM syndrome (HIGM) is a rare primary immunodeficiency disorder characterized by elevated or normal serum IgM and decreased IgG, IgA, and IgE due to defective immunoglobulin class switching. X-linked HIGM (XHIGM, HIGM1) is the most frequent type, is caused by mutations in the CD40 ligand gene, and is regarded as a combined T and B immunodeficiency. We report an 18-year-old male who was di...

Morbidity and Mortality of Iranian Patients with Hyper IgM Syndrome: a Clinical Analysis

Background: Defects in B cell class switch recombination (CSR) are a heterogeneous and yet very uncommon group of disorders which all have a genetic basis uniformly leading to hyper IgM (HIgM) syndrome. Due to the rare frequency of these conditions, a very small number of case series have been conducted on the affected patients. Objective: To shed some light on the morbidity and mortality regar...

Partial immune reconstitution of X-linked hyper IgM syndrome with recombinant CD40 ligand.

X-linked hyper IgM syndrome (XHM) is a combined immune deficiency disorder caused by genetic alterations in CD40 ligand. The purpose of this study was to investigate the safety and efficacy of recombinant CD40 ligand (rCD40L) in the treatment of the disease. Three children were administered rCD40L subcutaneously 3 times per week at 0.03 mg/kg for 22 weeks, and after a 12-week drug-free interval...
