ABSTRACT
Introduction: The coronavirus disease 2019 (COVID-19) pandemic has caused significant global disruption, especially for chronic care like hemodialysis treatments. Approximately 10,000 end-stage kidney disease (ESKD) patients are receiving maintenance hemodialysis (MHD) at 174 dialysis centers in Greater Mumbai. Because of the fear of transmission of infection and inability to isolate patients in dialysis centers, chronic hemodialysis care was disrupted for COVID-19-infected patients. Hence, we embarked on a citywide initiative to ensure uninterrupted dialysis for these patients. Materials and Methods: The Municipal Corporation of Greater Mumbai (MCGM) designated 23 hemodialysis facilities as COVID-positive centers, two as COVID-suspect centers, and the rest continued as COVID-negative centers to avoid transmission of infection and continuation of chronic hemodialysis treatment. Nephrologists and engineers of the city developed a web-based-portal so that information about the availability of dialysis slots for COVID-infected patients was easily available in real time to all those providing care to chronic hemodialysis patients. Results: The portal became operational on May 20, 2020, and as of December 31, 2020, has enrolled 1,418 COVID-positive ESKD patients. This initiative has helped 97% of enrolled COVID-infected ESKD patients to secure a dialysis slot within 48 hours. The portal also tracked outcomes and as of December 31, 2020, 370 (27%) patients died, 960 patients recovered, and 88 patients still had an active infection. Conclusions: The portal aided the timely and smooth transfer of COVID-19-positive ESKD patients to designated facilities, thus averting mortality arising from delayed or denied dialysis. Additionally, the portal also documented the natural history of the COVID-19 pandemic in the city and provided information on the overall incidence and outcomes. This aided the city administration in the projected resource needs to handle the pandemic.
ABSTRACT
We aimed to study the effect of remdesivir therapy on renal and hepatic function in coronavirus disease-2019 (COVID-19) patients with renal dysfunction at baseline or after starting therapy and identify the factors, if any, related to the efficacy of remdesivir therapy on patient outcome. Patients included in the study were those who met all the following criteria irrespective of baseline glomerular filtration rate [including those already on maintenance hemodialysis (HD)] or baseline deranged liver function test. (1) Age >18 years, (2) COVID-19 reverse transcriptase-polymerase chain reaction positive, (3) Meeting criteria for administration of remdesivir - [any one of the following: (a) COVID-19 pneumonia with respiratory rate >30/min or SPO2<94% on room air, (b) Acute respiratory distress syndrome (ARDS)]. (4) Renal dysfunction at baseline, during or within 48 h of completion of therapy. Thirty-four patients had renal dysfunction at baseline or developed it after remdesivir therapy - 16 were acute kidney injury (AKI), 10 chronic kidney diseases (CKD), four CKD stage 5D, and four were postrenal transplant. The overall mortality was 18/34 (52.9%). Eight out of 30 (26.66%) needed HD during or after therapy and of these, 15 died and among 15 survivors, 14 returned to their baseline renal function after cessation of therapy, one patient is still dialysis dependent. In the dialysis-dependent CKD (n = 4) subgroup, three died and one was discharged. In the postrenal transplant (n = 4) group, all developed AKI during or after the completion of therapy. None required HD, two returned to their baseline renal function, and two died. Only five had alanine aminotransferase elevation (×1 upper limit of normal) during or within 48 h of completion of therapy - three died and two returned to baseline. Lower PaO2/FiO2 (severe ARDS) (P = 0.0001), higher C-reactive protein (P = 0.022), higher serum lactate dehydrogenase (P = 0.038), and duration of symptoms before starting therapy (P = 0.05) were statistically significant variables at baseline associated with higher mortality. Remdesivir can be tried in moderate-to-severe COVID-19 cases with renal dysfunction as a complete recovery of renal function was noted in survivors. However, larger and well-controlled studies evaluating its safety and efficacy in patients with AKI and CKD are needed.
