title: X-linked agammaglobulinemia: a survey of 33 Iranian patients.
abstract: In order to determine the clinical and laboratory features of X-linked agammaglobulinemia, the records of 33 male patients with XLA were reviewed during 22 years (1980-2002) in the Iranian referral center of primary immunodeficiency disorders. The patients' ages ranged from 20 to 360 months (median 113 months). The median age at the onset of the disease was 8 months and the median age of diagnosis was 48 months, with a median diagnosis delay of 33 months. Almost all of the patients presented common infectious diseases, which were: pneumonia, otitis, diarrhea, sinusitis, and arthritis. During the course of illness, infections in the respiratory tract, gastrointestinal tract, central nervous system, and musculoskeletal system were seen in 93.9%, 75.8%, 33.3%, and 21.2% of XLA patients, respectively. The most common complications of these patients were chronic infections in 75.8% of them, including: chronic otitis media, chronic sinusitis, chronic diarrhea, and bronchiectasis.
