Abstract
AIM: The study aimed to describe clinical characteristics and outcomes of pregnant women with COVID-19 undergoing cesarean section, and evaluated the association of blood values at admission with severe COVID-19 disease in this group of patients. METHOD: We retrospectively analyzed the clinical data of 110 patients infected with COVID-19 who underwent cesarean section at Adana City Education and Research Hospital in Turkey. The COVID-19 severity of the patients was classified as either severe or nonsevere disease according to World Health Organization of COVID-19 clinical management guidance. We compared blood values, clinical characteristics, and outcomes between severe and nonsevere patients. Receiver operating characteristics (ROC) curves analyses and area under the ROC curve (AUC) value was calculated to evaluate the predictive value of blood parameters on the COVID-19 severity. RESULTS: Of the 110 women, 12 were severe cases. Severe patients had higher ferritin, neutrophil-to-lymphocyte ratio (NLR), lactate dehydrogenase (LDH), alanine transaminase (ALT), aspartate transaminase (AST), and procalcitonin levels on admission (p < 0.05). The ROC analysis demonstrated AUC of NLR, LDH, AST, ALT, ferritin, and procalcitonin was 0.757, 0.856, 0.840, 0.771, 0.821, and 0.698, respectively. The LDH had a maximum specificity (90.8%), with the cutoff value of 365. The O-blood group was more likely to have severe illness than the non-O-blood group (relative risk: 3.6; 95% confidence interval; 1.2-10.4). CONCLUSION: This study shows that LDH values at admission are an early and powerful predictor of severe infection for pregnant women with COVID-19 who will undergo a cesarean section.
