Opportunistic parasitic infections in HIV/AIDS patients presenting with diarrhoea by the level of immunesuppression.

Background & objectives: Enteric parasites are major cause of diarrhoea in HIV infected individuals. The present study was undertaken to detect enteric parasites in HIV infected patients with diarrhoea at different levels of immunity. Methods: The study was carried out at National AIDS Research Institute, Pune, India, between March 2002 and March 2007 among consecutively enrolled 137 HIV infected patients presenting with diarrhoea. Stool samples were collected and examined for enteric parasites by microscopy and special staining methods. CD4 cell counts were estimated using the FACS count system. Results: Intestinal parasitic pathogens were detected in 35 per cent patients, and the major pathogens included Cryptosporidium parvum (12%) the most common followed by Isospora belli (8%), Entamoeba histolytica/Enatmoeba dispar (7%), Microsporidia (1%) and Cyclospora (0.7%). In HIV infected patients with CD4 count < 200 cells/μl, C. parvum was the most commonly observed (54%) pathogen. Proportion of opportunistic pathogens in patients with CD4 count <200 cells/μl was significantly higher as compared with other two groups of patients with CD4 count >200-499 and ≥ 500 cells/μl (P=0.001, P=0.016) respectively. Interpretation & conclusions: Parasitic infections were detected in 35 per cent HIV infected patients and low CD4 count was significantly associated with opportunistic infection. Detection of aetiologic pathogens might help clinicians decide appropriate management strategies.

Rate of hospitalization and inpatient care costs for HIV-1-infected patients in Pune, India.

BACKGROUND: The transition of human immunodeficiency virus (HIV) infection to acquired immune deficiency syndrome (AIDS) has begun in India, and an increase in AIDS-related hospitalizations and deaths is an anticipated challenge. We estimated the rates of hospitalization and inpatient care costs for HIV-1-infected patients. METHODS: Data were analysed on 381 HIV-1-infected persons enrolled in a HIV-1 discordant couples' cohort between September 2002 and March 2004. Inpatient care costs were extracted from select hospitals where the study patients were hospitalized and the average cost per hospitalization was calculated. RESULTS: A majority of the patients were in an advanced state of HIV-1 disease with the median CD4 counts being 207 cells/cmm (range: 4-1131 cells/cmm). In all, 63 participants who did not receive antiretroviral therapy required hospitalization, 53 due to HIV-1-related illnesses and the remaining 10 due to worsening of pre-existing conditions. The overall HIV-1-related hospitalization rate was 34.2 per 100 person-years (95% CI: 26.94-42.93). The median duration of HIV-1-related hospitalization was 10 days (range 2-48 days) and the median cost was Rs 17,464 (range: Rs 400-63,891). CONCLUSION: It is necessary to strengthen the inpatient care infrastructure and supporting diagnostic set-up, and work out economically optimized treatment algorithms for HIV-1-infected patients. Although this analysis does not cover all costs and may not be generalizable, these baseline data might be a useful reference while planning related studies accompanying the government-sponsored programme to roll out antiretroviral therapy to AIDS patients.

Changing trends in clinical presentations in referred human immunodeficiency virus infected persons in Pune, India.

AIMS: To study profile and trends of clinical presentations among human immunodeficiency virus (HIV) infected individuals seen in a HIV Reference Clinic in Pune. METHODOLOGY: In a cross-sectional study, 3574 subjects were seen at a HIV Clinic in Pune from January 1997 to December 1999. Data on clinical presentation of 2801 (78.4%) HIV seropositive subjects were evaluated. RESULTS: Clinical conditions like oral thrush, tuberculosis, skin rash and sexually transmitted diseases showed decreasing trends during the three years study period (p=0.03, 0.02, < 0.01 and < 0.01, respectively). Conversely a significant increase in the number of asymptomatic HIV positive persons at the time of detection was observed over the same period (p < 0.01). CONCLUSION: Temporal change in the clinical presentations in the HIV positive persons referred to our clinic probably reflects increased awareness and a high index of suspicion among clinicians. Early diagnosis of HIV infection in asymptomatic phase might help the clinicians to make timely decisions on prescribing chemoprophylaxis for prevention of opportunistic infections and to take appropriate measures for prevention of secondary HIV transmission to the uninfected sex partners/spouses.
