Throughout the coronavirus disease 2019 (COVID-19) pandemic, a greater severity and lethality of the disease has been highlighted in male patients, so we set out to evaluate the prognostic role of serum testosterone levels in the clinical results of this population.
In this single-center and cross-sectional design, we included male patients admitted to our hospital with COVID-19 confirmed diagnosis. The biochemical analysis included lymphocytes, lactate dehydrogenase (LDH), total testosterone (TT), dehydroepiandrosterone, follicle-stimulating hormone, and luteinizing hormone. Receiver operating characteristic curves, univariate and bivariate analysis, and binary logistic regression for multivariate analysis were performed. A p value<0.05 was consider significant.
From 86 men included, 48.8% died. TT levels were lower in non-survivor patients than in survivor patients (4.01nmol/L [0.29-14.93] vs 5.41 (0.55-25.08) nmol/L, p=0.021). The independent risk factors that increased the relative risk (RR) of dying from COVID-19 were: age>59 years (RR 3.5 [95% IC 1.0-11.6], p=0.045), TT levels<4.89nmol/L (RR 4.0 [95% IC 1.2-13.5], p=0.027) and LDH levels>597IU/L (RR 3.9 [95% IC 1.2-13.1], p=0.024). Patients who required mechanical ventilation (p=0.025), had lymphopenia (p=0.013) and LDH levels>597IU/L (p=0.034), had significantly lower TT levels compared to those who did not present these conditions. There were no differences in TT levels between patients who had or did not have comorbidities.
A TT level<4.89nmol/L increase four times the RR of death from COVID-19 in men, regardless of age or presence of comorbidities.
