The aim of this study was to investigate the influence of HLA-A, -B and -C polymorphisms on the clinical course of SARS-CoV-2 infection and on the progression of COVID-19 in a population from southeastern Brazil. This study included 478 unvaccinated individuals. Of these, 369 were hospitalised with critical/severe (n = 309) or moderate/mild (n = 60) symptoms, and 109 were asymptomatic. The control group consisted of 150 volunteer bone marrow donors, recruited in the pre-pandemic period. The HLA-B*15 allele group (adjusted p value < 0.001) was associated with a protective factor against symptomatic infection. Investigating the effects of the distribution of HLA alleles on susceptibility and resistance to SARS-CoV-2 may provide a better understanding of the clinical course of infection in different geographical regions.
本研究的目的是调查HLA-A、-B和-C基因多态性对巴西东南部人群中SARS-CoV-2感染临床病程以及COVID-19进展的影响。本研究纳入了478名未接种疫苗的个体。其中，369人因严重/危重症（n = 309）或中/轻症（n = 60）症状住院，109人无症状。对照组由150名在疫情大流行前招募的志愿骨髓捐献者组成。HLA-B*15等位基因组（校正p值<0.001）与针对有症状感染的保护因素相关。研究HLA等位基因分布对SARS-CoV-2易感性和抗性的影响，可能有助于更好地理解不同地理区域的感染临床病程。
