Abstract: Introduction. Currently, COVID-19 treatment includes several options, including the use of convalescent plasma. Therefore, the presence of anti-SARS-CoV-2 in blood donors after the clinical recovery of COVID-19, depending on their place of residence, age and the clinical manifestation of the disease is of scientific-practical interest. Material and methods. A total of 119 donors among patients were examined, namely, males aged 18-60 years, having a past history of COVID-19 disease, being confirmed by PCR and treated, showing a negative PCR-based test result, which was performed at least 14 days after clinical recovery. The presence/absence of anti-SARS-CoV-2 was assessed by enzyme-linked immunosorbent assay. Results. The obtained data showed that 87.4% of plasma donors responded to COVID-19 infection by anti-SARS-CoV-2 IgG expression, being predominantly found in the 26-35 age group. Most donors experienced mild and medium clinical forms. It is important to note that all severe clinical manifestations of the infection were followed by formation of anti-SARS-CoV-2 IgG. Urban living environment was predominantly found in convalescent donors (75.0%), which indicates that they are better informed by medical institutions. Conclusions. The study shows that male blood donors aged 18-60 years, subsequently cured and being positive to anti-SARS-CoV-2 IgG can serve as a source of fresh plasma used for the treatment of COVID-19 patients
Introducere. Tratamentul COVID-19 include mai multe opțiuni, inclusiv utilizarea plasmei convalescente. Astfel, prezintă un interes științifico-practic existența anticorpilor anti SARS-CoV-2 la donatorii de sânge după recuperarea clinică de COVID-19, în funcție de mediul de trai, de vârstă și de forma de manifestare clinică a bolii. Material și metode. Au fost examinați 119 donatori din rândul pacienților, persoane de sex masculin, cu vârsta de 18-60 ani, cu istoric de boală COVID-19, caz confirmat prin PCR, vindecați, cu rezultat negativ pentru COVID-19, confirmat de testul PCR, la cel puțin 14 zile de la recuperarea clinică. Prezența/absența anti SARS-CoV-2 a fost apreciată prin analiza imunoenzimatică. Rezultate. Datele obținute relevă că 87,4% dintre donatorii de plasmă au răspuns la infecția COVID-19 prin expresia anti SARS-CoV-2 IgG, cu predominare în grupul de vârstă de 26-35 ani. Majoritatea donatorilor au făcut forma clinică ușoară și medie. Este important de menționat că toate formele clinice grave de manifestare a infecției au fost însoțite de producerea de anti SARS-CoV-2 IgG. Donatorii sunt preponderent din mediul urban (75%), fapt ce indică că aceștia sunt mai bine informați de instituțiile medicale. Concluzii. Donatorii de sânge de genul masculin, cu vârsta de 18-60 ani, au avut o imunogeneză activă în urma infectării cu SARS-CoV-2, manifestând un nivel înalt de pozitivitate la anticorpii infecției date.
