ABSTRACT: Background: It is yet a controversy subject whether low birth weight and infant
death are associated to human immunodeficiency virus-1 infection. Objective: To appreciate association between low birth weights, mother to child HIV
transmission and infant mortality in HIV-1 infected pregnant women delivering
between 2011 and 2016. Materials: We conducted 6 years cohort study in
urban Mali. Outcome included preterm delivery, small for gestational age,
infant survival status and HIV transmission. Comparison concerned women
clinical WHO stage, mother viro-immunological status, and newborn anthropometric parameters. Results: HIV-1 infected women
who delivered low birth weight newborn were 20.9% (111/531) versus 16.5%
(1910/11.546) in HIV negative patients (p = 0.016). CD4 T cell counts low than
350 T cells count were strongly associated to LBW (p = 0.000; RR = 3.03; 95% CI [1.89 - 3.16]).
There is no significant association between ART that was initiated during
pregnancy (p = 0.061, RR = 0.02; CI 95% (1.02 - 1.99)) or during delivery (p =
0.571; RR = 1.01; CI 95% (0.10 - 3.02)) and LBW delivery. In multivariate
analysis ART regimens containing protease inhibitor (PI) were lone regimens
associated with LBW ((p = 0.030; RR = 1.001; 95% confidence interval [1.28 - 3.80]).
Very low birth weight was statistically associated to women HIV infection
(adjusted relative risk, 2.02; p = 0.000; 95% confidence interval (2.17 - 4.10)). There is no
significant difference between mother to child HIV transmission rate in the two
HIV-infected pregnant women (10 infected children in group 2: MTCT rate 4.5%)
and 3 infected children in group 1 (MTCT rate: 2.7%) (p = 0.56; RR, 0.59; CI 95% (0.18 - 4.39)). In multivariate analysis, LBW was
associated with infant death (p = 0.001; RR = 2.04; CI 95% [1.04 - 5.05]). The median weight of infant at the moment of death in
group 1 was 851 g (IQR: 520 - 1833 g). Significant relationship was found
between infant death among LBW newborn with mother WHO stage 2 (p = 0.004; adjusted RR = 3.22; CI 95% [2.25 - 6.00]), CD4 T cells count
3 (p = 0.005; RR = 2.81; CI 95% [1.20 - 4.11]), PI
regimens (p = 0.030; RR = 1.00; CI 95% [1.28 - 3.80]). Conclusion: We confirm
increased risk of low birth weight and mother HIV-1 infection and we identified
strongest association between mortality in infant born to HIV-1 infected mother
and LBW.
