Evaluation of Kidney Function in Patients with COVID-19 at the Epidemiological Treatment Centre in CHNU Fann

Abstract

Alteration of renal function during SARS-CoV-2 infection is frequent and is associated with excess mortality. It is multifactorial, involving mechanisms more specific to COVID-19: viral invasion, endothelitis and thrombosis, activation of the renin-angiotensin-aldosterone system, and elevation of pro-inflammatory cytokines. Thus, the objective of this work was to assess renal function in patients with moderate and severe forms of COVID-19. This was a prospective cross-sectional study of patients with COVID-19. The parameters studied were age, sex, uremia, creatinine and glomerular filtration rate (GFR). All biological parameters were measured with the A15 Biosystems automated system (Barcelona, Spain) and the GFR was calculated according to the MDRD formula. Data processing was carried out with the SPSS (Statistical Package for Social Sciences) software version 23. Our study population consisted of 192 subjects with COVID-19, of which 111 were moderate and 81 were severe. The mean age of our subjects was 60 years and a sex ratio of 1.02. GFR assessment showed that 28% of the population had a lowered GFR (<60 mL/min/1.73m 2 ). Analysis of the results according to the clinical forms showed frequencies of 19% of disturbance of renal function for the moderate forms against 40% for the severe forms. Impaired renal function appears to be frequent in patients with severe SARS-CoV-2 infection and is associated with a bad prognosis. Any patient hospitalized with SARS-CoV-2 should benefit from an initial nephrological assessment which could be used as a marker to dictate the prognosis of the severity of COVID-19.
