Purpose. The aim of this study was to assess the men’s androgen status influence on the severity and outcomes (transfer of patients to the ICU or death) of COVID-19 required hospital hospitalization.
Materials and methods. The study included 151 hospitalized men with a confirmed diagnosis of COVID-19. To measure the severity of disease have been used Symptomatic Hospital and Outpatient Clinical Scale for COVID-19 (SHOCS-COVID). It includes the severity of the clinical condition (hyperthermia, shortness of breath, oxygen saturation, need for ventilation), the degree of inflammation (CRP), markers of thrombosis (D-dimer), the degree of lung damage according to CT. The patients underwent a study of full blood count, some biochemical parameters, lung CT, and a study of testosterone (T) and dihydrotestosterone (DHT) levels.
Results. T deficiency was observed in 46.4% of patients (70/151 men). At the same time, DHT deficiency was observed only in 14.4% of patients (18/125 men). In patients with a T level below the median, there was a significant increase in inflammatory factors (CRP, lymphocytes/CRP index), markers of thrombosis (D-dimer and fibrinogen), extensive lung damage at admission according to CT 25.75% vs. 11.95% (p<0.001), the elevated number of points for SHOCKS-COVID 7 (IQR 5-10) versus 5 (IQR 3-7) (p<0.001) and the longer duration of hospital treatment (3 days difference, p<0.001) in comparison with a group of patients with a T level above the median. At the same time, the T level had no correlation with age. The level of DHT had a weak inverse correlation with the age of patients, but not with the main markers of the severity of COVID-19, including the number of SHOCK-COVID scores.
During multivariate regression analysis, it was shown that SHOCKS-COVID is the most significant predictor of admission to the ICU while no association of T and DHT levels with outcomes in COVID-19 was found. However, it was found that the concentration of T, even adjusted for age, has a significant inverse association with the severity of the course of the disease and the number of SHOCK-COVID scores (p=0.041). An analysis of the evaluation of directed acyclic graphs suggests the main role of COVID-19 severity in reducing androgenic function and T concentration, at which its anti-inflammatory effects are lost. There were no correlations between the concentration of DHT and the number of SHOCK-COVID scores and the COVID-19 prognosis.
Conclusion. SHOCK-COVID is the most sensitive predictor of the COVID-19 outcome in hospitalized men, including adjusting to age. T and DHT do not directly affect the outcomes of the disease. The greater severity of the infection and an increase in SHOCK-COVID scores are associated with a decrease in the concentration of T, and a weakening of its anti-inflammatory and anti-cytokine effects, which indirectly worsens the prognosis of male patients with a new coronavirus infection undergoing hospital treatment. There are no such relationships for DHT.
