ABSTRACT
OBJECTIVE: The study aimed to evaluate the causes of thrombocytopenia in pregnancy and its management along with the outcome in the COVID-19 era. METHODS: Recruitment for this prospective, cross-sectional observational study of thrombocytopenia in pregnancy (platelet counts <100x109/L) was done from January 2017 to August 2020 at the National Institute of Blood Diseases (NIBD) after taking the patients' informed consent. Complete clinical and lab profile of patients was also collected. RESULTS: A total of 150 pregnant women with thrombocytopenia were enrolled, with the mean age being 27.3±4.64 years. Mean platelet counts at baseline were 48.0±24. Main clinical manifestations at baseline included: anemia 65.9%, bruises 23.25%, and edema 9.3%. Causes of thrombocytopenia were gestational thrombocytopenia (GT) 72 (48%), acute fatty liver five (3.3%), pre-eclampsia in 11 (7.3%), and eclampsia seven (4.6%). Causes not specific to pregnancy included 30 (20%) cases of ITP, hepatitis C, and nutritional deficiency was reported in nine (6%) patients each. 72/150 received supportive care treatment to manage thrombocytopenia and were closely monitored and given supplements. Twenty (66.6%) ITP patients received treatment with steroids, with complete response in 70% of them seen. Overall, 38 (25.3%) women with bleeding symptoms and platelet count <50x109/L received platelet transfusions. CONCLUSION: The study shows that pre-eclampsia and eclampsia are serious conditions with a high risk for complications, while GT is a benign and the most common cause of thrombocytopenia in pregnancy which requires no active treatment. The other causes such as ITP and infections require individualized management.
ABSTRACT
BACKGROUND: Covid-19 spread through blood transfusion has not yet been reported. Despite the prevailing pandemic, there are no recommendations available as yet for testing SARS-CoV-2 antibodies as part of blood screening. OBJECTIVE: To determine the seroprevalence of SAR-CoV-2 antibodies, its clinical significance and to identify if total antibodies(IgA, IgM, IgG) should be tested or just the specific IgG antibodies only. METHOD: Consecutive blood donors donated were screened for standard serological panel of HbsAg, Anti-HCV, Anti-HIV and Syphilis using Cobas-411 analyser and Malaria. All seronegative donors were then screened for COVID serology using the same instrument. These results were compared with the blood donors' seroprevalence checked in a cohort in the first week of June 2020. Pre-COVID-19 period (October 2019) blood donors' archived samples were also compared. Donors who were positive on ECLIA were then tested for specific antibodies (IgM or IgG) by ELISA. RESULTS: A total of 380 healthy blood donors were included. All were males with the mean age being 30.6 ± 6.3 years. Ten pre-pandemic samples did not show COVID-19 antibodies, whereas out of 70 samples in the 3rd week of June, only 15 (21.4 %) were positive. However, in July out of the 300 blood donors, 113 (37.7 %) were found to be reactive. To reconfirm our findings, these 113 donors were then tested on ELISA for presence of IgG specifically. Out of these 128 samples, 81 were IgG positive, 23 were borderline positive and 24 were negative. CONCLUSION: Almost 40 % of blood donors are now seroconverted for COVID-19. This is a reflection of widespread seroprevalence in the adult male population.
