摘要
Novel coronavirus,SARS-CoV-2 is responsible for causing a pandemic that has affected individuals worldwide,over 192 million people and about 4.1 million people died so far.The spread is ongoing and the numbers are still increasing.Numerous therapeutic approaches have been explored and developed during this pandemic.Immunotherapy with virus-specific antibodies in convalescent plasma(CP)has shown potential benefits for various pathogenic diseases.In many instances,it is the only available and safe management option for the COVID-19 patients.Here we describe two confirmed cases of COVID-19 from two different geographical areas that were managed with standard treatment modalities initially.Both of the patients were presented with high-grade fever,dry cough,and sore throat.Lab reports showed increased values of D-dimer,serum ferritin,leukocyte count(LC),Lactate dehydrogenase(LDH),and C-reactive protein(CRP).Chest X-ray showed bilateral infiltration(multifocal and bilateral ground-glass opacities and consolidations with peripheral and basal predominance),consistent with the previous reports on COVID-19 infection.The patients received conservative treatment according to the hospital's protocol.The convalescent plasma(from recovered patients)infusion was the last treatment given to both patients.After the convalescent plasma transfusion,both patients showed a reduction of viral load,an increase of anti-SARS-CoV-2 IgG and IgM antibodies,reduction in lung infiltration,with no adverse events.However,further randomized controlled trials are needed to investigate the full scope of safety and efficacy(both short and long-term)of convalescent plasma therapy for COVID-19 and other related infections.
