Relationship between kalemia and intensive care unit admission or death in hospitalized COVID-19 patients: A cohort study.

BACKGROUND: SARS-CoV-2 uses Angiotensin-Converting Enzyme 2 as a viral gateway to the cell and could interact with the renin-angiotensin-aldosterone system. Other studies have shown kalemia abnormalities in patients with severe forms of coronavirus disease 2019. Our goal was to assess the prognosis value of kalemia within ten days of symptom offset in the COVID-19 hospitalized population. METHODS: We analyzed data from a prospective cohort that included 65 patients with COVID-19, admitted between March 15, 2020, and March 21, 2020. The study aimed at determining the relationship between baseline kalemia and the admission to an intensive care unit (ICU) or death. RESULTS: The median age of the patients was 65 [54-79] years old, and 66.2% of the patients were men. Baseline kalemia under 3.8mmol/l occurred in 31 patients (48%), including 11 patients (35.5%) who were admitted to an ICU and one patient (3.2%) who died before ICU admission. In the primary end-point analysis, the adjusted hazard ratios for admission to an ICU or death were 3.52 [95% confidence interval (CI), 1.12 to 11.04] among patients with low baseline kalemia. CONCLUSION: Our study suggests that low kalemia levels within ten days of the first symptom onset might be associated with an increased risk of intensive care unit admission or death. The future perspective should be to better understand this relationship.

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.
