A Prospective Study on Impact of Early Initiation of Antiretroviral Therapy in Human Immunodeficiency Virus-Positive Adults on Immunological Status and Adverse Events.

INTRODUCTION

Antiretroviral therapy (ART) is a lifelong commitment for human immunodeficiency virus infection (HIV)-positive patients. The patients may develop early adverse drug reactions (ADRs) during the first 3 months of treatment, especially when they have advanced HIV disease with low CD4 counts.

MATERIALS AND METHODS

The present study was a prospective observational study that took place from January 2017 to July 2017 at ART center, Government Medical College, Amritsar, Punjab, India. The primary objective of the study was to evaluate ADRs to ART and immunological status in HIV-positive patients. The patients received ART regimens as per the National AIDS Control Organization guidelines. The sample included both ART-naïve and ART-experienced HIV-positive patients. The causality of reported ADRs assessed according to the World Health Organization guidelines. The study was conducted after taking approval from the Institutional Ethics Committee, Government Medical College, Amritsar, and informed consent from the patients. Data were analyzed statistically using Chi-square test, and < 0.05 was considered statistically significant.

RESULTS

Out of total 350 patients screened during study period, 84 patients reported with confirmed ADRs. The most widely used treatment regimen was tenofovir + lamivudine + efavirenz (59.52%). Central nervous system (19.05%)-, renal (14.29%)-, and immune reconstitution inflammatory syndrome (14.29%)-related ADRs were mostly reported. The causality assessment revealed insignificant value (Chi-square = 8.656 and = 0.07), with 19.05% probable and 80.95% possible ADRs.

CONCLUSIONS

The CD4 count <200/μl at the initiation of ART and treatment duration <1 year proved to be predictors for ADRs. Early initiation of ART in HIV-positive patients can improve immunological status and decrease in the incidence of ADRs.
