Major histocompatibility complex (MHC) class II deficiency is a rare autosomal recessive form of primary immunodeficiency disorder (PID) characterized by the deficiency of MHC class II molecules. This deficiency affects the cellular and humoral immune response by impairing the development of CD4+ T helper (Th) cells and Th cell-dependent antibody production by B cells. Affected children typical...
Primary immunodeficiencies (PID) are a group of disorders, characterized by an unusual susceptibility to infections. Delay in diagnosis results in increased morbidity and mortality in affected patients. The purpose of this study was to determine the mortality rate of Iranian immunodeficient patients referred to Children Medical Center Hospital affiliated to Tehran University of Medical Sciences...
A 43 year old female patient presented for recurrent bacterial lower respiratory infections. A research for immunodeficiency status revealed total hypogammaglobulinemia, reduced IgG1, IgG2, IgG3 subclass levels, and low number of B lymphocytes (CD19+). Common Variable Immunodeficiency (CVID) 11.2 category was diagnosed according to recent criteria of primary immunodeficiencies (PID). Further im...
Severe combined immunodeficiency (SCID) represents a rare group of primary immunodeficiency disorders (PIDs), with known or unknown genetic alterations. Here, we report a new interleukin 2 receptor, gamma chain (IL-2RG) mutation in an Iranian SCID newborn. The patient was a 6-day old boy with a family history of PID. The child was screened using a molecular-based analysis for the assessment of ...
BACKGROUND Patients with primary immunodeficiency (PID) often suffer from frequent respiratory tract infections. Despite standard treatment with IgG-substitution and antibiotics many patients do not improve significantly. Therefore, we hypothesized that additional immune deficits may be present among these patients. OBJECTIVE To investigate if PID patients exhibit impaired production of antim...
While landmark studies have shown that microbiota activate and educate host immunity, how immune systems shape microbiomes and contribute to disease is incompletely characterized. Primary immunodeficiency (PID) patients suffer recurrent microbial infections, providing a unique opportunity to address this issue. To investigate the potential influence of host immunity on the skin microbiome, we e...
autism is a neurodevelopmental disorder, characterized by poor social interaction and communication impairment and repetitive behavior. autism is considered as a genetic and multifactorial disorder, with diverse risk factors involved. herein, we report a 13-year-old male with common variable immunodeficiency (cvid), who was diagnosed with autism at the age of 3 years old. as there are some ...
