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.
ABSTRACT
BACKGROUND & OBJECTIVE: In India, data regarding mortality and clinical characteristics of hospitalized HIV-infected patients are sparse, which may limit the effectiveness of new hospital-based HIV programmes providing antiretroviral therapy (ART). The objective of our study was to determine mortality and clinical characteristics of hospitalized HIV-infected individuals in a high HIV prevalence region of India. METHODS: A retrospective chart review was done of known HIV-infected adults admitted to the Medical Service of a large, public hospital in Pune, India, from January 2002 to November 2003. RESULTS: A total of 655 HIV-infected patients were identified; 489 (74.7%) were male and 4 (0.6%) were on ART. The most common illnesses reported were tuberculosis (55.8%), diarrhoea (4.2%), and alcoholic liver disease (3.7%) . The inpatient mortality was 172 (26.3%). The most common causes of death of the 172 people were tuberculosis (52.9%) and cryptococcal meningitis (7.6%). In multivariate analysis, factors associated with increased mortality were male sex (adjusted odds ratio (AOR) 1.92, 95% CI: 1.08-3.41), haemoglobin level < 7 g/dl (AOR 2.75, 95% CI:1.23-6.14), length of stay < 2 days (OR 5.78, 95%, CI: 1.82-18.4), and cryptococcal meningitis (OR 4.44, 95% CI:1.19-16.6). INTERPRETATION & CONCLUSION: In the era prior to widespread ART, a high inpatient mortality of 26 per cent was found among hospitalized HIV-infected individuals. Thus, while hospitalization is an important access and referral point for HIV care and treatment, earlier identification of HIV-infected persons must occur to ensure they will optimally benefit from the government's ART programme.
