Hypogammaglobulinaemia associated with normal or increased IgM (the hyper IgM syndrome): a case series review.
The clinical and immunological aspects of 16 children with the syndrome of hypogammaglobulinaemia associated with normal or increased IgM (the hyper IgM syndrome) and their responses to treatment are reviewed. Increased concentrations of IgM, neutropenia, and recurrent infections could usually be controlled by antimicrobial and intravenous immunoglobulin treatment. Together with the bacterial i...
متن کاملMutations of CD40 gene cause an autosomal recessive form of immunodeficiency with hyper IgM.
CD40 is a member of the tumor necrosis factor receptor superfamily, expressed on a wide range of cell types including B cells, macrophages, and dendritic cells. CD40 is the receptor for CD40 ligand (CD40L), a molecule predominantly expressed by activated CD4(+) T cells. CD40/CD40L interaction induces the formation of memory B lymphocytes and promotes Ig isotype switching, as demonstrated in mic...
متن کاملHyper-IgM syndrome: a case report.
Hyperimmunoglobulin M syndrome is a rare primary immunodeficiency disorder. We report a case of a 6-month-old boy who suffered from developmental delays, frequent respiratory tract infection, and unusual fungal and bacterial infection. X-linked hyperimmunoglobulin M syndrome was ultimately diagnosed with decreasing immunoglobulin-G, A, and E (immunoglobulin G = 51.3 mg/dL, immunoglobulin A = 8....
متن کاملMorbidity 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...
متن کاملHyper IgM syndrome with tuberculous osteomyelitis and scrofuloderma.
INDIAN PEDIATRICS 952 VOLUME 42__SEPTEMBER 17, 2005 Hyper IgM syndrome (HIGM) is a rare primary immunodeficiency characterized by low levels of serum IgA and IgG and a normal or increased levels of IgM due to a block in the B cell immunoglobulin switch from IgM to IgG(1). The estimated incidence is approximately 1 in 10,30,000 live births(2). Two types are described X linked hyper IgM (XHIM) an...
