RESUMO
BACKGROUND: Whilst the impact of Covid-19 infection in pregnant women has been examined, there is a scarcity of data on pregnant women in the Middle East. Thus, the aim of this study was to examine the impact of Covid-19 infection on pregnant women in the United Arab Emirates population. METHODS: A case-control study was carried out to compare the clinical course and outcome of pregnancy in 79 pregnant women with Covid-19 and 85 non-pregnant women with Covid-19 admitted to Latifa Hospital in Dubai between March and June 2020. RESULTS: Although Pregnant women presented with fewer symptoms such as fever, cough, sore throat, and shortness of breath compared to non-pregnant women; yet they ran a much more severe course of illness. On admission, 12/79 (15.2%) Vs 2/85 (2.4%) had a chest radiograph score [on a scale 1-6] of ≥3 (p-value = 0.0039). On discharge, 6/79 (7.6%) Vs 1/85 (1.2%) had a score ≥3 (p-value = 0.0438). They also had much higher levels of laboratory indicators of severity with values above reference ranges for C-Reactive Protein [(28 (38.3%) Vs 13 (17.6%)] with p < 0.004; and for D-dimer [32 (50.8%) Vs 3(6%)]; with p < 0.001. They required more ICU admissions: 10/79 (12.6%) Vs 1/85 (1.2%) with p=0.0036; and suffered more complications: 9/79 (11.4%) Vs 1/85 (1.2%) with p=0.0066; of Covid-19 infection, particularly in late pregnancy. CONCLUSIONS: Pregnant women presented with fewer Covid-19 symptoms but ran a much more severe course of illness compared to non-pregnant women with the disease. They had worse chest radiograph scores and much higher levels of laboratory indicators of disease severity. They had more ICU admissions and suffered more complications of Covid-19 infection, such as risk for miscarriage and preterm deliveries. Pregnancy with Covid-19 infection, could, therefore, be categorised as high-risk pregnancy and requires management by an obstetric and medical multidisciplinary team.

The pathophysiology of severe coronavirus disease 2019 (COVID-19) is primarily a host immune interplay to virus invasion. The therapeutic options have been explored either against hyperinflammation from dysregulated adaptive immunity or direct virus neutralization using antibodies from convalescent plasma (CP) of a recovered patient. The therapeutic plasma exchange (TPE) for removal of excessive inflammatory cytokines has been tried with success in COVID-19. We undertook this exploratory study to evaluate safety and efficacy of TPE followed by CP transfusion in 14 patients with critical COVID-19 requiring invasive mechanical ventilation (IMV). All patients showed improvement in symptoms and decrease of inflammatory markers especially CRP (p = 0.03). 10 patients were liberated from IMV after a median of 5.5 (3-36) days, post sequential therapy. Day 7 and Day 28 mortality was 21.4% and 28.6% respectively. The median duration ICU and hospital LOS were 12 (5-42) days and 18 (12-47) days respectively. No patient developed transfusion-associated complications, but three patients developed secondary bacterial sepsis within 14 days of therapy, and one died. This case series demonstrated the sequential use of TPE followed by CP transfusion as a therapeutic option in critical COVID-19.
