41P Testosterone level and severity of COVID-19 infection in ambispective cohorts: The TESTOVID study

Background: Lower risk of COVID-19 was reported in men with prostate cancer receiving androgen deprivation therapy while low levels of testosterone (T) were associated with a more severe disease and poor clinical outcomes in COVID-19 male patients (pts). In the latter case, it is unclear whether low levels of T and dihydrotestoserone (DHT) are risk factors or consequences of COVID-19. Here, we investigated T and DHT levels impact on COVID-19 severity in ambispective cohorts of symptomatic SARS-CoV-2 infected males. Methods: Both prospective (European Hospital Georges Pompidou patients, P-cohort) and retrospective (French COVID-19 cohort, REacting project, R-cohort) cohorts included male pts admitted for severe COVID-19. The P-cohort included pts admitted in a medical unit (non-ICU) or in ICU immediately (ICU-I). The R-cohort included pts admitted to a medical unit, ICU-I or to ICU secondarily (ICU-S). The size of ICU-S pts group in P-cohort was insufficient to include their data in the analysis. We collected information on pts demographics and COVID-19-related outcomes. T, DHT levels and inflammation markers were measured. Wilcoxon-Mann-Whitney test and chi2-test (or Fisher’s exact test, if appropriate) were performed. All tests were two-sided at 0.05 significance level. Results: The P-cohort included 71 pts (median age: 64 years) and the R-cohort 89 pts (median age: 62 years). The median duration between admission and measurement of hormone levels was 2 days (range: 0-16) and 0.5 days (range: 0-11) respectively. T and DHT levels were low in all pts as compared to standards and even lower in ICU pts (Table). In the R-cohort, T and DHT lowest values were observed for ICU-I pts and median values for ICU-S pts. [Formula presented] Conclusions: Low T and DHT levels were associated with the severity of the disease and the poorest clinical outcomes in males with severe COVID-19. This suggests that COVID-19 may cause a rapid and profound decrease in androgens levels and that T and DHT serum levels may be used as prognostic markers. Legal entity responsible for the study: Pr.
