Abstract

Genetic predisposition to venous thrombosis may impact COVID-19 infection and its sequelae. Participants in the ongoing prospective cohort study, Million Veteran Program (MVP), who were tested for COVID-19, with European ancestry, were evaluated for associations with polygenic venous thromboembolic risk, Factor V Leiden mutation (FVL) (rs6025) and prothrombin gene 3’ -UTR mutation (F2 G20210A)(rs1799963), and their interactions. Logistic regression models assessed genetic associations with VTE diagnosis, COVID-19 (positive) testing rates and outcome severity (modified WHO criteria), and post-test conditions, adjusting for outpatient anticoagulation medication usage, age, sex, and genetic principal components. 108,437 out of 464,961 European American MVP participants were tested for COVID-19 with 9786 (9%) positive. PRS(VTE), FVL, F2 G20210A were not significantly associated with the propensity of being tested for COVID-19. PRS(VTE) was significantly associated with a positive COVID-19 test in F5 wild type (WT) individuals (OR 1.05; 95% CI [1.02-1.07]), but not in FVL carriers (0.97, [0.91-1.94]). There was no association with severe outcome for FVL, F2 G20210A or PRS(VTE). Outpatient anticoagulation usage in the two years prior to testing was associated with worse clinical outcomes. PRS(VTE) was associated with prevalent VTE diagnosis among both FVL carriers or F5 wild type individuals as well as incident VTE in the two years prior to testing. Increased genetic propensity for VTE in the MVP was associated with increased COVID-19 positive testing rates, suggesting a role of coagulation in the initial steps of COVID-19 infection.

Key Points

  • Increased genetic predisposition to venous thrombosis is associated with increased COVID-19 positive testing rates.

  • PRS for VTE further risk stratifies factor V Leiden carriers regarding their VTE risk.

    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    Study limitations are that only European ancestry participants were studied as PRS(VTE) was developed within cohorts of European ancestry. Only patients that were COVID-19 tested were included in this study. The last patients that were tested in the study cohort were on June 1 2021 so vaccination status might play a role in the study. The serotype of viruses involved was not known. Treatment modalities had evolved during the study period. Diagnosis of clinical events in the immediate post index period might be affected by potential underutilization of imaging modalities required to make certain diagnoses. The latter was expected to dissipate however after a recommended short period of quarantine and with longer follow up. An important consideration in the issue of testing positive rates was exposure. It is unlikely that PRS(VTE) was associated with differential environmental exposure however. Strengths include a large sample size and geographically diverse population evaluated, the prospective nature of this study to examine testing (positive) rates and clinical sequelae of COVID-19 infection, and the use of genetic stratification to investigate post COVID-19 events. In summary, PRS(VTE) was associated with COVID-19 positive testing rates for EUR in this large prospective cohort from the MVP. The linkage of COVID-19 infection with thromboembolism processes is novel and may reveal mechanisms of early steps of viral infection and/or treatment and prevention strategies.
