This fact raised concerns regarding the durability of the immune response and effective protection against severe Coronavirus disease 2019 (COVID-19) in this vulnerable population. The aim of our study was to evaluate the change in antibody levels over time in HDP population. Materials and Methods: We performed a prospective multicenter study, evaluating antibody response among HDP at 2 and at 6 months after complete two-dose vaccination course with the mRNA-BNT162b2 (Pfizer-BioNTech) vaccine. The study was performed in 14 hemodialysis units of a private dialysis provider in Lithuania. The serum samples of 189 HDP were tested for SARS-CoV-2 IgG against the Spike glycoprotein. Results: 189 HDP participated in the study. Patients were 64.3±15.7 years of age, 116 (61.4%) were males and 73 (38.6%) were females. Among them, 183 (96.8%) were seropositive for anti-S IgG at 2 months after the second immunization dose. Six months after the second dose only 145 (76.7%) of study participants had positive anti-S IgG titers. The median level of anti-S IgG titers after 2 months was 383.1 BAU/mL (166.2–995.6) and after 6 months this level significantly decreased to 51.4 BAU/mL (22.0–104.0) (p<0.001). Seroresponses at both time points inversely correlated with increasing patient’s age. Risk factor for absent response after 2 months included oncologic disease. Systemic autoimmune disease and a history of myocardial infarction increased risk to be seronegative 6 months after the second vaccine dose. Conclusions: The majority of hemodialysis patients seroresponded after BNT162b2/Pfizer vaccination, but vaccine-induced humoral immunity wanes over time. 2023 artículo científico 2029-4174 https://www.redalyc.org/articulo.oa?id=694074262003 https://www.redalyc.org/journal/6940/694074262003/ https://www.redalyc.org/journal/6940/694074262003/html/ https://www.redalyc.org/journal/6940/694074262003/694074262003.epub https://www.redalyc.org/journal/6940/694074262003/movil https://doi.org/10.15388/Amed.2023.30.1.3 en http://www.redalyc.org/revista.oa?id=6940 Acta medica Lituanica application/pdf Vilniaus Universitetas Acta medica Lituanica (Lituania) Num.1 Vol.30 |
