BackgroundIn people living with HIV (PLHIV) who are on anti-retroviral therapy (ART), it is essential to identify persons with high blood viral loads (VLs) (≥1000 copies/ml), provide enhanced adherence counselling (EAC) for 3 months and assess for VL suppression (<1000 copies/ml).ObjectiveOur study objectives were to determine the proportion who had a high viral load in those people who underwent viral load testing between 1 August 2016–31 July 2017 at Wilkins Hospital, Harare, Zimbabwe. Of those with high viral load to assess; a) the proportion who enrolled for EAC, the demographic and clinical characteristics associated with enrolment for EAC and, b) the proportion who achieved viral load suppression and demographic, clinical characteristics associated with viral load suppression.DesignRetrospective cohort study using routinely collected programme data. Data was collected from PLHIV who were on ART and had a high viral load from 1 August 2016 to 31 July 2017.ResultsOf 5,573 PLHIV on ART between 1 August 2016 and 31 July 2017, 4787 (85.9%) had undergone VL testing and 646 (13.5%) had high VLs. Of these 646, only 489 (75.7%) were enrolled for EAC, of whom 444 (69%) underwent a repeat VL test at ≥ 3 months with 201 (31.2%) achieving VL suppression. The clinical characteristics that were independently associated with higher probability of VL suppression were: a) undergoing 3 sessions of EAC; b) being on 2nd line ART. Initial VL levels >5,000 copies/ml were associated with lower probability of viral suppression.ConclusionThe routine VL testing levels were high, but there were major programmatic gaps in enrolling PLHIV with high VLs into EAC and achieving VL suppression. The full potential of EAC on achieving viral load suppression has not been achieved in this setting. The reasons for these gaps need to be assessed in future research studies and addressed by suitable changes in policies/practices.

BackgroundDespite high antiretroviral (ARV) treatment coverage among pregnant women for prevention of mother-to-child transmission (PMTCT) of Human Immunodeficiency Virus (HIV) in Zimbabwe, the MTCT rate is still high. Therefore in 2016, the country adopted World Health Organization recommendations of stratifying pregnant women into “High” or”Low” MTCT risk for subsequent provision of HIV exposed infant (HEI) with appropriate follow-up care according to risk status.ObjectiveThe study sought to ascertain, among pregnant women who delivered in clinics of Harare in August 2017: the extent to which high risk MTCT pregnancies were identified at time of delivery; and whether their newborns were initiated on appropriate ARV prophylaxis, cotrimoxazole prophylaxis, subjected to early HIV diagnostic testing and initiated on ARV treatment.MethodsCross-sectional study using review of records of routinely collected program data.ResultsOf the 1,786 pregnant women who delivered in the selected clinics, HIV status at the time of delivery was known for 1,756 (98%) of whom 197 (11%) were HIV seropositive. Only 19 (10%) could be classified as “high risk” for MTCT and the remaining 90% lacked adequate information to classify them into high or low risk for MTCT due to missing data. Of the 197 live births, only two (1%) infants had a nucleic-acid test (NAT) at birth and 32 (16%) infants had NAT at 6 weeks. Of all 197 infants, 183 (93%) were initiated on single ARV prophylaxis (Nevirapine), 15 (7%) infants’ ARV prophylaxis status was not documented and one infant got dual ARV prophylaxis (Nevirapine+Zidovudine).ConclusionThere was paucity of data requisite for MTCT risk stratification due to poor recording of data; "high risk" women were missed in the few circumstances where sufficient data were available. Thus "high risk" HEI are deprived of dual ARV prophylaxis and priority HIV NAT at birth and onwards which they require for PMTCT. Health workers need urgent training, mentorship and supportive supervision to master data management and perform MTCT risk stratification satisfactorily.
