Abstract
Background: The presence and level of anti-SARS-CoV-2 antibodies in PLWH from the Lower Silesia region in Poland. Material and Methods: A total of 216 serum samples of both sexes, aged 21–77, and treated with TDF or TAF together with FTC and INSTI at two points of time. Anyone who did not experience COVID-19 symptoms. Samples were checked for the presence and levels of anti-SARS-CoV-2 antibodies regarding CD4 + T and CD8 + T cells counts, the ratio of these cells, age, sex, VL, and type of tenofovir used. Results: The average level and prevalence of anti-SARS-CoV-2 antibodies during the first wave were 65.81 IU/mL and 4.17%, while during the second wave, they were 125.98 IU/mL and 14.29%, respectively. There was a significant correlation between the number and type of lymphocytes and the presence of anti-SARS-CoV-2 antibodies. We did not find the same correlation regarding anti-SARS-CoV-2 levels. The average level of antibodies was higher during the second wave. There was no difference between the type of tenofovir used and the humoral response, as well as no correlation of anti-SARS-CoV-2 levels with age, gender, or VL. Conclusion: PLWH can have asymptomatic SARS-CoV-2 infection, which can influence the presence, but not levels, of anti-SARS-CoV-2 Ab. No correlation with type of tenofovir was observed.
