ABSTRACT
This was a cross-sectional study describing HIV testing uptake and ART initiation for pregnant women and HIV-exposed infants after one-off clinical mentorship training in 2013 for nurses in 56 peripheral health-facilities, Zimbabwe. Between 2014-2018, 92% of 106411 pregnant women were HIV tested and 98% of HIV-positive women initiated antiretroviral therapy (ART). There were 15846 HIV-exposed infants, of whom 96% had dried blood spots collected for virologic diagnosis and 51% of those diagnosed HIV-positive initiated ART. In conclusion, this one-off clinical mentorship training in 2013 was associated with consistently high HIV testing and ART initiation in pregnant women and their children.

BACKGROUND: Zimbabwe is one of the thirty countries globally with a high burden of multidrug-resistant tuberculosis (TB) or rifampicin-resistant TB (MDR/RR-TB). Since 2010, patients diagnosed with MDR/RR-TB are being treated with 20-24 months of standardized second-line drugs (SLDs). The profile, management and factors associated with unfavourable treatment outcomes of MDR/RR TB have not been systematically evaluated in Zimbabwe. OBJECTIVE: To assess treatment outcomes and factors associated with unfavourable outcomes among MDR/RR-TB patients registered and treated under the National Tuberculosis Programme in all the district hospitals and urban healthcare facilities in Zimbabwe between January 2010 and December 2015. METHODS: A cohort study using routinely collected programme data. The 'death', 'loss to follow-up' (LTFU), 'failure' and 'not evaluated' were considered as "unfavourable outcome". A generalized linear model with a log-link and binomial distribution or a Poisson distribution with robust error variances were used to assess factors associated with "unfavourable outcome". The unadjusted and adjusted relative risks were calculated as a measure of association. A ðvalue< 0.05 was considered statistically significant. RESULTS: Of the 473 patients in the study, the median age was 34 years [interquartile range, 29-42] and 230 (49%) were males. There were 352 (74%) patients co-infected with HIV, of whom 321 (91%) were on antiretroviral therapy (ART). Severe adverse events (SAEs) were recorded in 118 (25%) patients; mostly hearing impairments (70%) and psychosis (11%). Overall, 184 (39%) patients had 'unfavourable' treatment outcomes [125 (26%) were deaths, 39 (8%) were lost to follow-up, 4 (<1%) were failures and 16 (3%) not evaluated]. Being co-infected with HIV but not on ART [adjusted relative risk (aRR) = 2.60; 95% CI: 1.33-5.09] was independently associated with unfavourable treatment outcomes. CONCLUSION: The high unfavourable treatment outcomes among MDR/RR-TB patients on standardized SLDs were coupled with a high occurrence of SAEs in this predominantly HIV co-infected cohort. Switching to individualized all oral shorter treatment regimens should be considered to limit SAEs and improve treatment outcomes. Improving the ART uptake and timeliness of ART initiation can reduce unfavourable outcomes.

SETTING: Four primary health care clinics providing tuberculosis (TB) and Human Immunodeficiency Virus care services in Bulawayo, Zimbabwe. OBJECTIVES: To assess isoniazid preventive therapy (IPT) initiation and completion, factors associated with IPT uptake and incidence of TB, and TB and antiretroviral treatment (ART) outcomes among people living with HIV (PLHIV). DESIGN: This was a cohort study using routine data in the records for PLHIV initiated on ART from October 2013 to March 2014 with 31 December 2017 as the end of the follow-up period. RESULTS: A total of 408 PLHIV were eligible for IPT, 214 (52%) were initiated on IPT and 201 (94%) completed IPT. No person in the IPT-initiated group developed Tuberculosis (TB). Six persons with TB were reported among the non-IPT-initiated group leading to an incidence of 9 cases/1,000 person-years of follow-up. About 70% of those who developed and were treated for TB had a successful TB treatment outcome. The survival on ART at four years of follow-up was 88% among the IPT-initiated PLHIV that was significantly higher than the 75% survival in the group not- initiated on IPT. CONCLUSION: The study revealed low IPT initiation among eligible PLHIV who, if started on IPT, completed the six month regimen. TB was reported only among the PLHIV not-initiated on IPT and the four year ART survival was higher in the IPT-initiated group than in the non-initiated group. These findings reinforce the need to strengthen IPT uptake among PLHIV in Bulawayo.
