Opportunistic infections in relation to CD4 level among HIV seropositive patients from central Nepal.

CD4 cells status of HIV patients provides one of the benchmarks against the progression of HIV/AIDS. Regular investigation of opportunistic infection in HIV patients is one of the major components of HIV/AIDS care and support service. Between October 2007 and May 2008, a cross-sectional analytical study was carried out in Tribhuvan University Teaching Hospital with an objective to find the relationship between CD4 level and opportunistic infections. After taking informed consent pre-structured questionnaire was filled and specimens were collected to investigate major opportunistic infections (OIs) as per standard microbiological procedure. All the information were entered into SPSS 11.5 system and analyzed. Of the 150 patients, 100 (66.7%) were males and 50 (33.3%) were females. The age group 21-30 years was predominant (42.7%) followed by 31-40 years (42%). Oral candidiasis was found to be the predominant OIs (32.0%) followed by streptococcal pneumonia (28.7%), Salmonella infection (20.7%), cryptosporidial infection (19.3%) and tuberculosis (10.0%). Significant relationship could be established between low CD4 count (<200) and the appearance of oral candidiasis (/2=9.16, p<0.05) but no such relationship could be established regarding other OIs. So, it can be concluded that appearance of oral candidiasis is the strong evidence of advanced stage of HIV infection.
