ABSTRACT
Introduction: Cryptococcal meningitis is one of the leadingopportunistic infections associated with high mortality. Thepresent study was carried out to determine the prevalence ofcryptococcal antigenemia in HIV-infected patients with CD4+T-cell count ≤ 200 cells/μl.Material and methods: A cross-sectional study includinga total of 100 blood samples of HIV-infected patients withCD4+ T-cell count ≤ 200 cells/μl was carried out in a tertiarycare hospital. The Cryptococcal Antigen Latex AgglutinationTest was performed on serum separated from blood samplesincluded in the study group. A positive cryptococcalantigenemia was diagnosed by positive latex agglutinationtest of cryptococcal polysaccharide antigen in serum. BMI ofall patients included in the study group was calculated andWHO clinical staging of all patients was noted.Results: Three cases out of 100 were positive for cryptococcalantigenemia. The positive cases showed correlation with lowBMI and WHO Clinical stage II and III of HIV disease. Inthe present study, 33.33% and 66.67% of positive cases hadCD4+ T-cell count within the range of 0-100cells/μl and101-200cells/μl respectively.Conclusion: It is important to implement routine screeningfor cryptococcal antigen among HIV-infected cases withCD4+ T-cell count ≤ 200 cells/μl for early detection ofcryptococcal antigenemia. It will help in identifying the riskof subsequent cryptococcal meningitis and initiation of preemptive antifungal treatment.
