High blood pressure at entry into antenatal care and birth outcomes among a cohort of HIV-uninfected women and women living with HIV initiating antiretroviral therapy in South Africa.

ABSTRACT:

Objective

To examine associations between high blood pressure (BP) when entering antenatal care (ANC) and birth outcomes in a cohort of pregnant HIV- and women living with HIV (WLHIV) initiating antiretroviral treatment (ART).

Study design

Prospective cohort study.

Main outcome measures

Cesarean delivery, preterm birth (<37 weeks' gestation), low birthweight (LBW, <2500 g), small-for-gestational age (SGA, <10th percentile), and large-for-gestational age (LGA, >10th percentile for GA).

Results

Of 1116 women (median GA 20 weeks; WLHIV 53%), 48% (53% WLHIV; 43% HIV-) entered ANC with high BP, defined as elevated (120-129 or < 80 mmHg), stage 1 (>130-139 or 80-89) or stage 2 hypertension (≥140 / or ≥ 90). WLHIV were more likely to have high BP (RR 1.32; 95%CI 1.12-1.57), controlling for pre-pregnancy body mass index and additional confounders. In multivariable analysis, there was no evidence that high BP increased the risk of cesarean delivery (RR 1.10, 95% CI 0.92-1.30), preterm birth (RR 1.15, 95% CI 0.81-1.62), LBW (RR 1.16, 95% CI 0.84-1.60) or SGA (RR 1.02, 0.72-1.44), overall or when stratified by HIV-status. High BP was associated with an increased risk of LGA (RR 1.43; 95% CI 1.00-2.03).

Conclusion

In this setting, half of women had high BP at entry into ANC, with WLHIV at increased risk of high BP. There was no strong evidence that high BP increased the risk of adverse birth outcomes overall, or by HIV-status, with the exception of LGA. WLHIV may be at high risk of high BP during pregnancy and should be monitored closely.

Project description:BACKGROUND:Inflammation and hemostasis perturbation may be involved in vascular complications of HIV infection. We examined atherogenic biomarkers and subclinical atherosclerosis in HIV-infected adults before and after beginning highly active antiretroviral therapy (HAART). METHODS:In the Women's Interagency HIV Study, 127 HIV-infected women studied pre and post HAART were matched to HIV-uninfected controls. Six semiannual measurements of soluble CD14, tumor necrosis factor (TNF) alfa, soluble interleukin (IL) 2 receptor, IL-6, IL-10, monocyte chemoattractant protein 1, D-dimer, and fibrinogen were obtained. Carotid artery intima-media thickness was measured by B-mode ultrasound. RESULTS:Relative to HIV-uninfected controls, HAART-naive HIV-infected women had elevated levels of soluble CD14 (1945 vs 1662 ng/mL, Wilcoxon signed rank P < 0.0001), TNF-? (6.3 vs 3.4 pg/mL, P < 0.0001), soluble IL-2 receptor (1587 vs 949 pg/mL, P < 0.0001), IL-10 (3.3 vs 1.9 pg/mL, P < 0.0001), monocyte chemoattractant protein 1 (190 vs 163 pg/mL, P < 0.0001), and D-dimer (0.43 vs 0.31 ?g/mL, P < 0.01). Elevated biomarker levels declined after HAART. Although most biomarkers normalized to HIV-uninfected levels, in women on effective HAART, TNF-? levels remained elevated compared with HIV-uninfected women (+0.8 pg/mL, P = 0.0002). Higher post-HAART levels of soluble IL-2 receptor (P = 0.02), IL-6 (P = 0.05), and D-dimer (P = 0.03) were associated with increased carotid artery intima-media thickness. CONCLUSIONS:Untreated HIV infection is associated with abnormal hemostasis (eg, D-dimer), proatherogenic (eg, TNF-?), and antiatherogenic (eg, IL-10) inflammatory markers. HAART reduces most inflammatory mediators to HIV-uninfected levels. Increased inflammation and hemostasis are associated with subclinical atherosclerosis in recently treated women. These findings have potential implications for long-term risk of cardiovascular disease in HIV-infected patients, even with effective therapy.
