Clinical manifestations and the risk of developing AIDS were studied in a cohort of 32 HIV-seropositive patients referred by their treating physicians to the Center for Medical Investigation of the Catholic University of Chile. The only exclusion criteria were a CD4 lymphocyte count below 400 or marked symptoms of AIDS. The study design included an examination at entry and every 6 months thereafter for a maximum follow up of 3 years. A multivariate analysis was conducted to determine the relation between disease progression and control and causal variables. The subjects were 8 women averaging 38 years old and 24 men averaging 33 years. Most were middle class and had higher education. 46% of the men became sexually active before age 15 and 42% were homosexual. HIV transmission was sexual in 28 subjects, through intravenous drug use in 2, and by unknown route in 2. The subjects had been infected for an average of 4.3 years at entry into the study. Of the 30 whose date of infection was known, 16 developed AIDS during the study according to the criterion of CD4 lymphocyte count below 200, and 8 of these developed markers of AIDS. 50% of patients developed AIDS 6.5 years after infection and 82% 8 years after. Using clinical criteria, 50% of patients had developed AIDS 8 years after infection. Multivariate analysis showed only subject's age at infection (faster progression at higher ages) and length of time since infection to be related to the risk of developing AIDS. No association was observed between development of the disease and sex, sexual orientation, use of alcohol or drugs, smoking, history of sexually transmitted diseases, number of sexual partners, or frequency of sexual relations. The most frequently observed pathologies before the stage of AIDS were acute diarrhea, sexually transmitted diseases, oral candidiasis, sinusitis, and varicela zoster infections. In the patients who progressed to AIDS, the decline of the CD4 lymphocyte count below 200 always preceded other symptoms. Two patients showed no significant decline in CD4 lymphocyte count or clinical manifestations of AIDS more than 8 years after infection.

Inherited neutropenia is characterized by a decrease in the absolute number of circulating neutrophils and an increased susceptibility to infections. The current study was performed to determine the clinical and laboratory findings of Iranian patients with inherited neutropenias. Records of 26 patients (14 male, 12 female) with inherited neutropenia were reviewed in this study. The patients had been referred to Children's Medical Center, a referral center for immunodeficiency disorders in Iran, during a 22-year period (1981-2003). Primary immunodeficiency disorders of these patients were as follows: cyclic neutropenia (8 patients), Shwachman-Diamond syndrome (7 patients), Kostmann syndrome (6 patients), and Chediak-Higashi syndrome (5 patients). The mean absolute neutrophil count of patients was 398.2 +/- 259.3 cells/mm (range 74-1,152/mm) at the first visit. Twenty-one patients showed severe, four moderate, and one mild neutropenia. Sixteen of these patients had leukopenia, seven anemia, two thrombocytopenia, and one monocytosis. The most common presenting complaints in these patients were oral ulcer, otitis, pneumonia, diarrhea, cutaneous abscess, and oral candidiasis. The patients first manifested symptoms of infection suggesting neutropenia at a median age of 7.5 months (range 1 month to 10 years). During follow-up, respiratory infections developed in 24 cases, oral manifestations in 20 patients. The most common infections, in descending order of frequency, were otitis media, abscesses, pneumonia, oral ulcers, acute diarrhea, cutaneous infections, oral candidiasis, and periodontitis. Less frequent infections were sinusitis, cystitis, conjunctivitis, meningitis, and osteomyelitis. Nonspecific symptoms (hepatomegaly and splenomegaly) were also detected in 10 patients and 1 patient, respectively. Three patients died of recurrent infections. The infectious manifestations both at presentation and during follow-up in inherited neutropenia were similar. Although inherited neutropenias are rare, recurrent infections always deserves further evaluation for detecting such disorders.

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.
