Increased risk of severe clinical course of COVID-19 in carriers of HLA-C*04:01

Abstract

Background: Since the beginning of the coronavirus disease 2019 (COVID-19) pandemic, there has been increasing urgency to identify pathophysiological characteristics leading to severe clinical course in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Human leukocyte antigen alleles (HLA) have been suggested as potential genetic host factors that affect individual immune response to SARS-CoV-2. We sought to evaluate this hypothesis by conducting a multicenter study using HLA sequencing.

Methods: We analyzed the association between COVID-19 severity and HLAs in 435 individuals from Germany (n = 135), Spain (n = 133), Switzerland (n = 20) and the United States (n = 147), who had been enrolled from March 2020 to August 2020. This study included patients older than 18 years, diagnosed with COVID-19 and representing the full spectrum of the disease. Finally, we tested our results by meta-analysing data from prior genome-wide association studies (GWAS).

Findings: We describe a potential association of HLA-C*04:01 with severe clinical course of COVID-19. Carriers of HLA-C*04:01 had twice the risk of intubation when infected with SARS-CoV-2 (risk ratio 1.5 [95% CI 1.1-2.1], odds ratio 3.5 [95% CI 1.9-6.6], adjusted p-value = 0.0074). These findings are based on data from four countries and corroborated by independent results from GWAS. Our findings are biologically plausible, as HLA-C*04:01 has fewer predicted bindings sites for relevant SARS-CoV-2 peptides compared to other HLA alleles.

Interpretation: HLA-C*04:01 carrier state is associated with severe clinical course in SARS-CoV-2. Our findings suggest that HLA class I alleles have a relevant role in immune defense against SARS-CoV-2.

Association between alleles and categorical response parameters in data sets, DS 1–3. Each dot represents one allele / response parameter association. Colors correspond to response parameters in the meta-analysis (intensive care unit, ICU status and intubation status). The Y-axis represents the negative logarithm of the p-value obtained from the logistic regression test. Sizes of dots correspond to the calculated effect size of the associations (log-odds ratios). Dashed vertical line corresponds to the minor allele frequency selection threshold (0.05). Dashed horizontal line corresponds to p-value of 0.05 (not corrected for multiple testing).

Colors correspond to variable status. The vertical axis shows the absolute number of patients. Data sets, DS 1–3.

Meta-analysis on HLA-C*04:01 and COVID-19 susceptibility.Odds ratios (Effect column) for each variant and the corresponding 95% confidence intervals (CI) are plotted as horizontal bars with a square in the middle. The size of the square is proportional to the weight of the corresponding cohort in the meta-analysis. The overall effect for the fixed-effect model is plotted as a diamond and vertical dotted line. For those cohorts where HLA alleles were not studied, we consider rs5010528 as tag SNP for HLA-C*04:01. Effective sample size (Eff. Sample Size) was calculated as 4/(1/N_cases + 1/N_controls). RAF: risk allele frequency.
