ABSTRACT
INTRODUCTION: Targeted HIV 1 viral load testing has been recommended in 2010 only for suspected cases of antiretroviral therapy failure. India is committed to achieve UNAIDS '90-90-90' target by 2020. The third 90 target was to ensure all people receiving antiretroviral therapy (ART) are virologically suppressed. Implementation of routine viral load testing in national programme helps us in assessing early treatment failure and the need to switch to second line therapy; thus eventually reducing drug resistance and improving patient outcomes. AIMS: Study was aimed to determine the proportion of patients responding to antiretroviral therapy, correlates of viral suppression & the discordance between virological and immunological failure. DESIGN: Retrospective analysis. MATERIAL & METHODS: As per the NACO policy, all patients diagnosed as HIV positive are started on antiretroviral therapy and are monitored regularly. The patient's adherence details are noted down during regular follow up visit and patient is referred for routine HIV 1 VL and/or CD4 testing as per National guidelines. Analysis of data was carried out retrospectively for all patients referred for HIV 1 viral load and/or CD4 testing during the study period from July 2019 to June 2020. Confidentiality of the patient was maintained at all times as per routine protocol. RESULTS: A total of 7601 PLHIV on antiretroviral therapy, 3813 samples were tested for both HIV 1 VL and CD4 counts and these results were further analyzed. 3616 (94.8%) showed virological suppression and 197(5.2%) showed virological failure. Among virologically failed group, 46.2% (91/197) underwent retesting after adherence counseling and among these 48.4%(44/91) showed viral suppression. Virological failure was significantly high in younger PLHIV receiving second or third line ART for less than 5 years duration who were non adherent. Immunological discordance was seen in 28.3 % of PLHIV. CONCLUSION: In the present study, 95.99% patients showed virological suppression indicating that the third "90"target is being exceeded.
