Serum hepatic biomarkers in women with obstetric cholestasis and a concurrent SARS-CoV-2 infection.

ABSTRACT

AIM: The aim of the study was to evaluate the association between SARS-CoV-2 infection and serum hepatic biomarker levels among women with obstetric cholestasis. METHODS: In this prospective study, we recruited all pregnant women admitted in our hospital with obstetric cholestasis. Among those with a concurrent SARS-CoV-2 infection, we evaluated the following serum hepatic biomarkers aspartate aminotransferase (AST), alanine aminotransferase (ALT), and biliar acids (BA). RESULTS: Among the 88 women enrolled in the study, 20 presented with a SARS-CoV-2 infection while 68 were negative. SARS-CoV-2 infected women were younger (mean age 30.5 ± 5.7 vs. 34.3 ± 5.4; p < 0.01) and in a greater percentage of non-Caucasian ethnicity when compared to noninfected women (60.0% vs. 17.6%; p < 0.01). Regarding levels of hepatic biomarkers, they showed higher levels of AST (111.5 ± 134.1 vs. 37.3 ± 43.4 UI/L; p = 0.02), ALT (132.2 ± 115.7 vs. 50.5 ± 73.173.1 UI/L; p < 0.01), and BA (41.4 ± 46.8 vs. 18.4 ± 13.4 µmol/L; p = 0.04) compared to noninfected patients. No significant differences in maternal or fetal outcomes were found between infected and noninfected women. CONCLUSION: SARS-CoV-2 infection was associated with higher levels of liver enzymes in patients with obstetric cholestasis. This could be the result of a possible hepatic involvement in patients with SARS-CoV-2 infection.
