Use of convalescent plasma in pregnant women with early stage COVID-19 infection in a tertiary care hospital in Dubai, February to March 2021: a case series study.

BACKGROUND: The use of COVID-19 convalescent plasma (CCP) for the treatment of SARS-CoV-2 infection in pregnancy is intriguing in view of its safety profile in pregnancy and historical precedence of the use of plasma for other viral illnesses. This study aimed to evaluate the use of CCP in pregnant women with early COVID-19 infection. METHODS: This is a retrospective case series study. We have included seven pregnant women admitted with early COVID-19 infection to a tertiary care hospital, Latifa Maternity Hospital in Dubai, United Arab Emirates between 12 February and 04 March 2021 and who consented to receive COVID-19 convalescent plasma as part of their treatment plan. Main outcomes measured were clinical and radiological features, laboratory tests, WHO clinical progression scale pre and post treatment, and maternal, fetal outcomes. COVID-19 clinical severity was classified according to the NIH guidelines for criteria of SARS-CoV-2. For the radiological features, a modified chest X-ray scoring system was used where each lung was divided into 6 zones (3 on each side upper, middle, and lower). Opacities were classified into reticular, ground glass, patchy and dense consolidations patterns. RESULTS: Seven pregnant women with early COVID-19 were enrolled in this study, their mean age was 28 years (SD 3.6). Four had comorbidities: 2 with diabetes, 1 with asthma, and 1 was obese. Five patients were admitted with a WHO clinical progression score of 4 (hospitalized; with no oxygen therapy) and 2 with a score of 5 (hospitalized; oxygen by mask/nasal prongs). Upon follow up on day 10, 6 patients had a WHO score of 1 or 2 (asymptomatic/mild symptoms) indicating clinical recovery. Adverse reactions were reported in 2 patients, one reported a mild skin rash, and another developed transfusion related circulatory overload. All patients were discharged alive. CONCLUSION: CCP seems to be a promising modality of treating COVID-19 infected pregnant women. However, further studies are needed to ascertain the efficacy of CCP in preventing progressive disease in the management of COVID-19 infection in pregnant women.

An Insight on the Maternal-Fetal Outcomes of Critically Ill Pregnant Women During the Second Wave of COVID-19.

BACKGROUND:  Coronavirus disease 2019 (COVID-19) and other respiratory infections have been attributed to causing severe disease and pneumonia in pregnant women because of physiological stress and alterations in the immune system during pregnancy. Pregnant women are prone to develop serious outcomes for both mother and child when infected by previous coronaviruses, but there is a paucity of data regarding clinical characteristics and maternal-fetal outcomes in COVID-19. Moreover, various laboratory and radiological parameters are scarcely studied in pregnant women in the third trimester who develop severe COVID-19. Therefore, we conducted this study to assess and compare the maternal-fetal outcomes of critically ill pregnant women with COVID-19 pneumonia who required admission to the intensive care unit (ICU). MATERIALS AND METHODS:  We conducted this retrospective observational study at a tertiary care hospital affiliated with an academic center in the United Arab Emirates. A total of 123 patients in their third trimester were included in the study from December 1, 2020, to March 31, 2021, comprising 30 cases of severe or critical COVID-19 and 93 mild to moderate COVID-19 patients. We collected and analyzed maternal demographic data and radiological and biochemical profiles. We also compared maternal-fetal outcomes. RESULTS:  Thirty patients (24.3%) were admitted to the ICU, and eight required invasive ventilation. Severe COVID-19 pneumonia was significantly associated with higher mortality (20% vs. 0%; p < 0.001), postpartum complications (50% vs. 9.67%; p < 0.001), and increased overall hospital stay than mild to moderate COVID-19 (p < 0.001). In addition, the primary indication for intervention in severe cases was worsening of COVID-19 pneumonia, and pregnant patients had significantly greater chances of undergoing delivery by Cesarean section (80% vs. 40.8%; p = 0.01). Neonates born to severe COVID-19 patients had significantly higher chances of being born preterm (76.6% vs. 35.7%; p < 0.001) and had low birth weight (46.6% vs. 13.9%; p-value = 0.002). There were four stillbirth cases, two vertical transmission cases, and no neonatal deaths. CONCLUSIONS:  This study assessed and compared maternal-fetal outcomes of critically ill pregnant women with COVID-19 pneumonia who required admission to the ICU because of the paucity of data in this patient demographic. Pregnant women with severe COVID-19 have high mortality, peripartum complications, increased hospital stay, and are more likely to undergo Cesarean section delivery because of COVID-19 progression than pregnant patients with less severe forms of COVID-19. The newborns born to such mothers may be premature and have low birth weights but have similar mortality to those born to mothers with mild to moderate COVID-19.
