Purpose: To evaluate associations between CD4/CD8 ratio and pregnancy outcomes in women with HIV. Methods: We evaluated, in a national study of pregnant women with HIV receiving antiretroviral treatment (ART), values of CD4/CD8 ratio at entry in pregnancy, changes between first and third trimester, and possible associations with preterm delivery, low birthweight, and HIV-RNA < 50 copies/ml at third trimester in univariate and multivariate analyses. Results: Among 934 women, 536 (57.4%) were already on ART at conception. CD4/CD8 ratio (baseline value 0.570) increased significantly between the first and third trimesters, particularly in women who started ART in pregnancy (+ 0.163, vs. + 0.036 in women already on treatment). The rate of CD4/CD8 ratio normalization, defined by achieving a ratio ≥ 1 at the third trimester, was 13.2%. In multivariable analyses, women who entered pregnancy with a CD4/CD8 ratio < 0.3, compared to women with ratio ≥ 1, were almost four-times less likely to have third-trimester HIV-RNA < 50 copies/ml (AOR 0.258, 95%CI 0.111-0.601), and more than twice as likely to have preterm delivery (AOR 2.379, 95%CI 1.082-5.232). For preterm delivery, also a baseline CD4/CD8 ratio between 0.3 and 0.45 was significantly associated with an increased risk (AOR: 3.415, 95%CI 1.690-6.900). Conclusion: We described for the first time independent associations of low CD4/CD8 ratio with preterm delivery and HIV-RNA suppression.

Methods: We evaluated, in a national study of pregnant women with HIV receiving antiretroviral treatment (ART), values of CD4/CD8 ratio at entry in pregnancy, changes between first and third trimester, and possible associations with preterm delivery, low birthweight, and HIV-RNA < 50 copies/ml at third trimester in univariate and multivariate analyses. Results: Among 934 women, 536 (57.4%) were already on ART at conception. CD4/CD8 ratio (baseline value 0.570) increased significantly between the first and third trimesters, particularly in women who started ART in pregnancy (+ 0.163, vs. + 0.036 in women already on treatment). The rate of CD4/CD8 ratio normalization, defined by achieving a ratio ≥ 1 at the third trimester, was 13.2%. In multivariable analyses, women who entered pregnancy with a CD4/CD8 ratio < 0.3, compared to women with ratio ≥ 1, were almost four-times less likely to have third-trimester HIV-RNA < 50 copies/ml (AOR 0.258, 95%CI 0.111-0.601), and more than twice as likely to have preterm delivery (AOR 2.379, 95%CI 1.082-5.232). For preterm delivery, also a baseline CD4/CD8 ratio between 0.3 and 0.45 was significantly associated with an increased risk (AOR: 3.415, 95%CI 1.690-6.900).
