RESUMEN

INTRODUCTION: The corticosteroid dosing modulation in renal transplant recipients (RTRs) with coronavirus disease-19 (COVID-19) is not well defined. We aimed to analyze the outcomes and infectious and non-infectious sequelae in RTR with COVID-19 with reference to corticosteroid dosing and the first and second pandemic waves of COVID-19. MATERIALS AND METHODS: This study included RTRs admitted during two pandemic waves between March 25, 2020, and July 31, 2021. Patients were categorized into mild, moderate, and severe COVID-19. The outcomes and predictors of survival at 4 weeks were analyzed. The survivors were also followed for 6 months and were studied for mortality, readmission rates, and infectious and non-infectious sequelae with reference to high-dose and standard-dose corticosteroids. RESULTS: A total of 251 RTRs, 104 during the first wave and 147 during the second wave, were treated. Overall mortality was 15.1% (11.5% in the first wave vs. 17.5% in the second wave, p = .23). The use of high-dose steroids was also significantly high in non-survivors (85.8% vs. 11.3%, p = .001). On multivariate analysis, the severity of COVID-19, graft dysfunction, and high dose of corticosteroid therapy were associated with increased odds of mortality. Among survivors, 6-month mortality (17.3% vs. 0.5%, p = .001), readmission rate (91.3% vs. 23.7%, p = .001), fungal infection (30.4% vs. 2.2%, p < .001), and post-COVID lung sequelae (21.7% vs. 4.4%, p = .008) were significantly higher in the high-dose corticosteroid group than in the standard-dose group. CONCLUSION: High-dose corticosteroid dosing in RTRs with COVID-19 was associated with increased infections, particularly fungal infections, and non-infectious sequelae with higher mortality on subsequent follow-up.

RESUMEN

INTRODUCTION: Asymptomatic maintenance hemodialysis patients with acute respiratory corona virus-2 (SARS-COV-2) are missed with pre-dialysis screening without testing. The possible ideal strategy of testing each patient before each shift with reverse transcription polymerase chain reaction (RT-PCR) is not feasible. We aimed to study the effectiveness of fortnightly screening with RT-PCR for SARS-CoV-2 in curbing transmission. METHODS: Between July 1, 2020 and September 30, 2020, all 273 patients receiving hemodialysis were subjected to fortnightly testing for SARS-Cov-2 in the unit to detect asymptomatic patients. The cost and effectiveness of universal testing in preventing transmission were analyzed using susceptible-infectious-removed (SIR) modeling assuming R0 of 2.2. RESULTS: Of 273 MHD patients, 55 (20.1%) found infected with SARS-CoV-2 over 3 months. Six (10.9%) were symptomatic, and 49 (89.1%) asymptomatic at the time of testing. Six (10.9%) asymptomatic patients develop symptoms later, and 43 (78.2%) remained asymptomatic. A total of seven (6.1%) HCWs also tested positive for the virus. Fortnightly universal testing is cost-effective, and SIR modeling proved effective in preventing person-to-person transmission. CONCLUSIONS: Repeated universal testing in maintenance hemodialysis patients detected 89% of asymptomatic SARS-CoV-2 patients over 3 months and appeared to be an effective strategy to prevent person-to-person transmission in the dialysis unit.
