RESUMO
CONTEXT: Coronavirus Disease 2019 (COVID-19) was declared as a pandemic by the World Health Organization (WHO) on March 11, 2020. COVID-19 disproportionately affects patients with pre-existing comorbidities including those undergoing dialysis at intermittent intervals. These patients requiring renal replacement therapy like intermittent hemodialysis have a preponderance to go into severe clinical states. Hence, this study was planned to analyze the outcomes of such patients requiring dialysis and suffering from the COVID-19 disease. OBJECTIVES: This study was carried out to compare the outcomes of the COVID-19 patients requiring hemodialysis with those not requiring hemodialysis. MATERIALS AND METHODS: This cross-sectional observational study was carried out between April 2020 and August 2020 at a dedicated COVID-19 hospital and included COVID-19 patients requiring hemodialysis at the time of admission and an equal number of controls matched for age and sex. RESULTS: The study included 271 COVID-19-positive patients requiring dialysis and 271 COVID-19-positive controls without the requirement of a dialysis matched for age and sex; 10.3% cases needed intensive care. There were 18.8% deaths in cases as opposed to 8.9% among controls. Multivariate analysis showed that advancing age (OR 2.6 in cases and 1.06 in controls) need for intensive care (OR 27.9 in cases and 331 in controls), and diabetes alone and with other comorbidities were significant predictors of mortality. CONCLUSIONS: This study showed that the mortality proportions were more in cases as compared to controls; and advancing age, diabetes, and need for intensive care unit (ICU) were significant predictors. The study also highlighted the crisis faced by patients who require dialysis at regular intervals due to this COVID-19 pandemic.
