| Abstrakt: | Background We aimed to assess the postnatal pattern of cardiovascular remodeling associated with intrauterine exposure to maternal HIV and antiretroviral treatment (ART). Methods Prospective cohort including 34 HIV-exposed uninfected (HEU) infants and 53 non-HIV-exposed infants were evaluated from fetal life up to 6 months postnatally. A cardiovascular evaluation was performed including echocardiography, blood pressure, and carotid intima media thickness (cIMT) measurement. Results ART regimens during pregnancy included 2 nucleoside reverse transcriptase inhibitors (Abacavir + Lamivudine (32.4%), Emtricitabine + Tenofovir (41.2%), and Zidovudine + Lamivudine (20.6%)). At 6 months of age, HIV-exposed uninfected infants showed thicker myocardial walls (septal wall thickness mean 5.02 mm (SD 0.85) vs 3.98 mm (0.86); P <.001), relative systolic dysfunction with decreased mitral ring displacement (8.57 mm (2.03) vs 10.34 mm (1.84); P =.002), and decreased tricuspid S' (9.71 cm/s (1.94) vs 11.54 cm/s (2.07); P =.003) together with relative diastolic dysfunction showed by prolonged left isovolumic relaxation time (58.57 ms (13.79) vs 47.94 (7.39); P <.001). Vascular assessment showed significantly higher systolic and diastolic blood pressure (102 mmHg (16.1) vs 80 mmHg (13.9); P <.001 and 64 mmHg (14.4) vs 55 mmHg (10.2); P =.045 respectively), with 50% of HIV-exposed children meeting criteria for hypertension vs 3.77% of the non-HIV-exposed group (P <.001) and thicker mean cIMT in the HIV-exposed group (0.62 µm (0.09) vs 0.51 µm (0.09); P =.015). Conclusions Subclinical cardiac impairment together with higher blood pressure and thicker cIMT were observed in HIV-exposed infants at 6 months of age. Half of them presented hypertension. Our findings support a possible increased cardiovascular risk in HIV uninfected infants exposed in utero to ART. [ABSTRACT FROM AUTHOR] |
