Chronic granulomatous disease (CGD) is a rare immunodeficiency due to a genetic defect in one of the NADPH-oxidase components. We studied CGD inheritance forms (autosomal recessive (AR) or X-linked (XL)) and AR-CGD subtypes in Iran. Clinical and functional investigations were conducted in 93 Iranian CGD patients from 75 families. Most of the patients were(More)
This study focuses on endoscopic and pathologic alterations of gastrointestinal (GI) disorders of Iranian patients with common variable immunodeficiency (CVID). Nineteen of 39 CVID patients (48%) had GI complaints. The most common symptom was chronic diarrhea (28%). In endoscopic examination of small intestines, 15 patients had no abnormal finding. Duodenal(More)
Adverse Drug Reactions (ADRs) and drug allergies- as a subset of ADRs- make a significant public health concern, complicating 5 to 15% of therapeutic drug courses. They may result in diminished quality of life, increased physician visits, health care costs, hospitalizations, and even death. The incidence of serious ADRs in hospitalized patients was(More)
Griscelli syndrome type 2 is an autosomal recessive disorder characterized by pigmentary dilution and occurrence of acute phases of hemophagocytosis. The disease is caused by mutations in RAB27A gene, coding a small GTPase involved in terminal phases of cytotoxic granule/melanosome exocytosis. We describe the result of mutation analysis among nine patients(More)
Severe congenital neutropenia (SCN) is a rare primary immunodeficiency. Different genes are found to be associated with SCN, including ELA2, HAX1, WAS, GFI1, G-CSFR. Also, recently G6PC3 as a rare gene in SCN has been reported. Patients with G6PC3 often have cardiac and/or urogenital malformations. Two patients with persistent severe neutropenia, recurrent(More)
Pediatric patients with leukocyte adhesion deficiency type-I (LAD-I) experience severe and recurrent life-threatening bacterial infections with failure of pus formation and delayed wound healing. LAD-I is a rare inherited disease caused by mutation in the leukocyte CD18 integrin expression, resulting in defective adherence and migration of leukocytes, in(More)
Neutropenia is characterized by decrease in the absolute number of circulating neutrophils and an increase susceptibility to infections. The current study was performed in order to explain the clinical and laboratory findings of patients with antibody deficiency disorders associated neutropenia. The patients' records of 19 neutropenic cases out of 207(More)
Chronic granulomatous disease (CGD), a rare inherited primary immunodeficiency disorder, is caused by mutation in any one of the genes encoding components of nicotinamide adenine dinucleotide phosphate (NADPH)-oxidase enzyme. NCF2 gene (encoding P67-phox component) is one of them and its mutation is less common to cause CGD (around 5-6%). Here, we assessed(More)
Insulin has an important role in the treatment of diabetic patients. Further, it can result in undesirable side effects. One of the problems that are associated with insulin therapy is allergic reactions. Although insulin allergy is uncommon, especially in patients with type-2 diabetes, but when it occurs, its management can be difficult. We report a(More)
Primary antibody deficiencies are the most frequent primary immunodeficiency disorders. Bronchiectasis as a feature of these disorders may be developed due to some factors such alpha-1- antitrypsin deficiency. In order to determine the prevalence of two common alpha-1-antitrypsin deficiency alleles (PI*Z and PI*S) in Iranian patients with antibody(More)
