Objective:To assess cardiovascular effects of in-utero HIV and antiretroviral treatment (ART) exposure on offspring of HIV-positive mothers in Ethiopia.Design:HIV-positive and HIV-negative pregnancies were identified from a prospective cohort of women recruited at their first antenatal care visit in Ethiopia, using a nested case-control design.Methods:Fetal standard ultrasound and echocardiography were performed at 2237 weeks of pregnancy to assess fetal biometry and cardiac structure. Postnatal cardiovascular evaluation, including echocardiography and vascular assessment, was performed at 6 months of age. Cardiovascular data were correlated to HIV serostatus, antiretroviral drug exposure and HIV-unrelated maternal characteristics.Results:Fetuses from 29 HIV-positive and 67 HIV-negative women paired by gestational age at scan were included. Among HIV-positive women, 25 were on ART before conception, and 4 initiated ART during pregnancy. Estimated fetal weight was similar in both groups [mean 1873 g (standard deviation; SD 569) vs. 1839 g (SD 579) P = 0.79, respectively]. Fetal cardiac morphometry was similar with regard to maternal HIV serostatus: cardiothoracic ratio mean 0.26 (SD 0.05) vs. 0.25 (SD 0.06), P = 0.48; and septal wall thickness mean 4.03 mm (SD 0.58) vs. 3.98 mm (SD 0.70), P = 0.94. No significant cardiovascular differences were detected postnatally according to maternal HIV serostatus: septal wall thickness mean 5.46 mm (SD 0.65) vs. 5.49 (SD 0.89); P = 0.896; isovolumic relaxation time 55.08 ms (SD 6.57) vs. 56.56 (SD 6.74); P = 0.359.Conclusion:In offspring of Ethiopian women, intrauterine exposure to HIV and ART were not associated with cardiovascular changes from fetal life up to infanthood.
