Assessment of antinuclear antibodies, anti-beta 2-glycoprotein-1, and thyroid peroxidase autoantibody levels in human immunodeficiency virus sero-positive pregnant women at Nnamdi Azikiwe University Teaching Hospital, Nnewi Nigeria

Abstract

Background: Pregnancy is associated with biochemical alterations and may be compounded by human immunodeficiency virus (HIV) infection potentially affecting pregnancy outcome. Aims: This study evaluated some biochemical parameters that could possibly affect pregnancy outcomes in HIV-infected women. Patients, Materials and Methods: The study involved 136 HIV sero-positive on highly active antiretroviral therapy (HAART) and 137 HIV sero-negative pregnant women, recruited from the Antenatal Clinic of Nnamdi Azikiwe University Teaching Hospital, Nnewi. Antinuclear antibodies (ANAs), anti-beta 2-glycoprotein-1 (βGP1), and thyroid peroxidase autoantibody (TPOab) were analysed using the enzyme-linked immunosorbent assay methods. Results: TPOab in HIV sero-positive subjects (104.9 ± 51.06 IU/mL) was significantly higher (P > 0.05) compared with controls (89.5 ± 33.5 IU/mL). ANA and βGP1 in test group (0.89 ± 0.31; 12.94 ± 8.9, respectively) did not change significantly (P > 0.05) compared with the controls (0.84 ± 0.27; 10.37 ± 9.6, respectively). There were no significant changes in measured biochemical parameters between trimesters (P > 0.05). Furthermore, there were no significant differences in measured biochemical parameters between subjects with different APGAR scores in all subject groups. Conclusion: HIV infection affected TPOab level but had no impact on ANA, βGP1, and APGAR score in HIV pregnancy under HAART.
