ABSTRACT
Immunodeficiency and autoimmune disease may occur concomitantly in the same individual. Some of the immunodeficiency syndromes, especially humoral defects are associated with autoimmune disorders. Hematological manifestations such as thrombocytopenia and hemolytic anemia are the most common presentations. Persistent antigen stimulation due to an inherent defect in the ability of the immune system to eradicate pathogens is the primary cause leading to autoimmunity in patients with primary immunodeficiency states. We describe a 10 year old Iranian girl with chronic granulomatous disease -the autosomal recessive type with mutation of NCF1 gene P47- associated with selective IgA deficiency, refractory immune thrombocytopenia that showed an excellent response to Rituximab [Anti-CD20 monoclonal antibody]. Patients with primary immunodeficiencies may have variable autoimmune manifestations. So for early detection and appropriate treatment, autoimmune diseases should always be suspected in such patients

Chronic granulomatous disease [CGD] is a rare disorder of phagocytes, predisposes patients to bacterial and fungal infections. The main purpose of this study was to determine the clinical, radiological, pathologicial features, outcome and response to treatment of children with CGD. Thirteen patients with CGD, who had been referred to National Research Institute of Tuberculosis and Lung Disease [NRITLD], were reviewed during a 6 year period [1999-2005]. There were 10 [76%] male and 3[24%] female cases. The median age of the patients was 9 years [1 month-12 years].Family history of CGD was reported by 7 patients. The median diagnostic age was 8 years, with a diagnostic delay of 4.5 years. The most common manifestations of CGD were pulmonary infections and skin involvement, followed by generalized lymphadenopathy. The most common radiological findings were multiple lymphadenopathy in mediastinal region and fibrotic changes in lung fields. Two patients died of pulmonary infections. Based on the results of this research, immunologic evaluations especially evaluation for CGD is highly recommended in children suffering from recurrent pulmonary infections, cutaneous or hepatic abscesses, or infections caused by uncommon pathogens. Early diagnosis and prophylactic treatment both, prevent further development of the lesions, irreversible complications and decreasing mortality and morbidity rates in children suffering from CGD
ABSTRACT
Chronic Granulomatous Disease [CGD] represents a group of inherited disorders of phagocytic system, manifesting recurrent infections at different sites. The present study was accomplished in order to determine the gastrointestinal manifestations of CGD patients. Fifty-seven patients [38 males and 19 females] with CGD, who had been referred to three immunodeficiency referral centers in Iran, were studied during a 24-year period [1980-2004]. The median age at the time of study was 14.5 years old [1-56 years]. The median onset age of symptoms was 5 months [1 month - 13.75 years], and that of diagnostic age was 5 years [2 months- 54.1 years], with a diagnostic delay of 33 months, on average. Seven patients were presented with acute diarrhea, 3 with oral candidiasis, and 2 with liver abscesses as the first chief complaints. Twenty-four cases [42.1%] had been complicated by gastrointestinal manifestations during their course of the disease. Of those, 12 cases [21.1%] had diarrhea, 7 [12.3%] oral candidiasis, 5 [8.8%] hepatitis, 4 [7.0%] hepatic abscess, and 2 cases [3.5%] gastric outlet obstruction. Also, failure to thrive was detected in 6 patients [10.5%]. Four patients died [7%]. CGD should be excluded in any patient with gastrointestinal manifestations especially chronic diarrhea, hepatic abscess, and gastric outlet obstruction
