[An analysis of opportunistic infection in 762 inpatients with human immunodeficiency virus infection in Guangdong areas].
OBJECTIVE
To analyze the characteristics of opportunistic infection (OI) in patients with HIV/AIDS in Guangdong and the relationship between OI and the change in blood CD4+ T lymphocyte count (CD4+).


METHODS
Seven hundred and sixty two patients with HIV/AIDS admitted were analyzed.


RESULTS
Among all the 762 patients, 704 (92.39%) had more than one kind of OI, with 1428 episodes totally. Etiologically, fungus infection (38.38%) was most common, followed by bacteria (36.20%), and virus (7.77%) infection. Most OI occurred in the lungs (33.05%), mouth (26.89%), skin (10.29%) and gastro-intestine (8.96%). Septicemia and other systemic disseminated diseases accounted for 6.58% and 9.94% respectively. The incidence of OI in patients with CD4+≥200/µl (103/136, 75.74%) was significantly lower than that in patients with CD4+<200/µl (601/626, 96.01%), P<0.01. All the AIDS defining OI were found in patients with CD4+<200/µl. Among them, 81.97% of patients with pneumonia carinii pneumonia (PCP), 71.43% of patients with cytomegalovirus retinitis and all the patients with cryptococcal meningitis, disseminated cryptococcosis, disseminated histoplasmosis, mycobacterium avium intracellular complex (MAC), disseminated penicilliosis marneffei and toxoplasma cerebritis had the CD4+ less than 50/µl.


CONCLUSIONS
The most common OI in patients with AIDS in Guangdong area are fungi, bacterial and viral infections. Lung, mouth, skin, gastro-intestine and systemic disseminated infections are the most prevalent infections. As the CD4+ decreased, the incidence of OI especially AIDS defining OI increased. Dynamic detection of CD4+ will be of great help for the prediction, prevention, early diagnosis and treatment of OI in patients with AIDS.
