Expression Levels of PF4, ALOX12, ITGA2B, F131A in Pregnant COVID-19 Survivors.

Abstract

COVID-19 is viral illness caused by SARS-CoV-2. The immediate complications of COVID-19 are well defined and associated with increased mortality. A global effort is required to determine its effects on implantation, fetal growth and labor. Post COVID-19 recovery period presents a further challenge regarding service provision, prevention, and management. To assess the expression of Platelet Factor 4 (PF4), Arachidonate 12-lipoxygenase (ALOX 12), Integrin alpha-IIb (ITGA2B) & Coagulation Factor XIII A Chain F13A1 in post-acute COVID-19 survivors pregnant women. Prospective case control study, conducted on 400 pregnant women. Case group consists of 200 singleton pregnancies who had recovered from COVID-19 since 4-6 weeks before conception. Control group consists of 200 singleton pregnancies with no history for COVID-19. Expression levels of ALOX12, PF4, ITGA2B, and F13A1genes were determined using quantitative reverse transcription polymerase chain reaction method (qRT-PCR). Expression levels of ALOX12, ITGA2B, and F13A1, were significantly higher in the patients group (3.82±9.6, 6.63±8.45, and 8.9±9.1, respectively) (p < 0.05) compared to those in the control group (1.0±6.0, 1.0±8.1, and 0.6±7.6, respectively). No significant difference in PF4 expression between patients and control group (p = 0.3). Results obtained from enrichment analysis have also supported the above findings. Relative expression levels of these candidate genes could be distinguished between post-acute COVID-19 survivors' pregnant women and control group, significant relative gene expression of ALOX12, ITGA2B, and F13A1 may be associated with an increased risk of placenta-mediated adverse pregnancy outcomes.
