Abstract
BackgroundRoutine viral-load (VL) measurements along with enhanced adherence counselling (EAC) are recommended to achieve virological suppression among people living with HIV/AIDS (PLHA) on anti-retroviral therapy (ART). The Mumbai Districts AIDS Control Society along with Médecins Sans Frontières has provided routine VL measurements and EAC to PLHA on ART at King Edward Memorial (KEM) hospital, Mumbai since October-2016. This study aims to describe the initial VL results and impact of EAC on viral suppression and factors associated with initial viral non-suppression among patients with an initial detectable VL, in a cohort of patients tested between October-2016 and September-2018.MethodsThis is a descriptive study of PLHA on ART who received VL testing and EAC during October-2016 to September-2018. Log-binomial regression was used to identify factors associated with a high VL.ResultsAmong 3849 PLHA who underwent VL testing, 1603(42%) were female and median age was 42 years (IQR:35–48). Majority were referred for routine testing (3432(89%)) and clinical/immunological failure (233(6%)). Overall, 3402(88%) PLHA had suppressed VL at initial testing. Among 3432 tested for routine monitoring, 3141(92%) had VL suppressed. Of 291 with VL>1000c/ml, 253(87%) received EAC and after repeat VL, 70(28%) had VL<1000c/ml. Among 233 referred for clinical/immunological failure, 122(52%) had VL>1000c/ml and 109 have been switched to second-line ART.CD4 count<500 (aOR-5.0[95%CI 3.8–6.5]), on ART for<5 years (aOR-1.5[1.1–2.0]) and age<15 years (aOR-5.2[3.0–8.9]) were associated with an initial VL>1000c/ml. Factors associated with follow-up VL suppression included EAC (p<0.05) and being on second-line ART (p<0.05).ConclusionResults from a routine VL program in public sector in India were encouraging and in line with UNAIDS 90-90-90 targets. Routine VL monitoring along with EAC resulted in early switch to alternative optimised regimens while also preventing unnecessary switches. Along with the vital scale up of routine VL monitoring, implementation of enhanced adherence strategies for patients with detectable viral load should be ensured.

Summary
The HIV/AIDS epidemic continues with 36.9 million people living with HIV/AIDS (PLHA) globally in 2017 [1]. India is committed to achieve the UNAIDS 90-90-90 targets, which specify that 90% of PLHA should know their HIV status, 90% diagnosed with HIV should be on ART and 90% of those on ART should have viral suppression [3,4]. The World Health Organization (WHO) recommends VL as the preferred approach to ART monitoring compared to clinical or immunological criteria [5] This is due to the fact that a decrease in CD4 count, which is a marker of immunological failure, occurs as result of viral replication, which can be considered as an endpoint [6]. This study aims to describe the initial VL results and impact of EAC on viral suppression and factors associated with initial viral non-suppression among patients with an initial detectable VL, in a cohort of patients tested between October-2016 and September-2018.
