Abstract
Background
Developments in South Africa’s prevention of mother-to-child transmission of HIV (PMTCT) programme show a decline in AIDS-related paediatric deaths. In 2015, PMTCT guidelines were updated, with revised protocols for clinical and laboratory monitoring for patients on antiretroviral therapy (ART). The aim of this study was to assess adherence to monitoring guidelines for HIV-positive pregnant women on ART. Methods This was a clinical audit of 185 HIV-positive pregnant women, on pre-pregnancy ART, or initiated during the index pregnancy and delivered at Charlotte Maxeke Johannesburg Academic Hospital (CMJAH) in the period January to June 2017. Data were collected on timing of HIV diagnosis and ART initiation, clinical and laboratory monitoring, and initiation of prophylaxis for opportunistic infections.
Results
Of the 185 patients, 64.9% (120/185) were known with HIV infection prior to the index pregnancy, and 85.8% (103/120) were initiated on ART pre-pregnancy, with 64/103 (62.1%) virally suppressed (<50 copies/ml)d t baseline. Overall, 179/185 women accessed antenatal care. A total of 82 patients were initiated on ART in the index pregnancy, and of these 60/82 (73.2%) had a 3-month viral load done, and 22/82 (26.8%) were suppressed. A total of 153/185 (82.7%) patients had CD4 counts done, and of these, 63/153 (41.2%) were ≤350 cells/dl, with 7/63 (11.1%) patients receiving cotrimoxazole prophylaxis. Tuberculosis (TB) screening was documented for 35/179 (19.6%) patients, with 6/35 (17.1%) receiving TB preventative therapy. Birth HIV PCR tests were available for 175/185 (94.6%) neonates, and all were negative.
Conclusion
There were gaps identified in laboratory and clinical monitoring. ART initiation was however high, with no cases of MTCT reported.
