The coronavirus disease 2019 (COVID-19) pandemic, instigated by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has profoundly impacted healthcare infrastructures around the globe. While children are usually asymptomatic or have mild symptoms, children with pre-existing kidney conditions require specialized attention. This pivotal report, championed by the International Pediatric Nephrology Association (IPNA), delivers precise and actionable recommendations tailored for pediatric patients with kidney ailments in this pandemic landscape. Central to our findings are rigorous infection control protocols. These are particularly stringent in high-risk zones, emphasizing telehealth's indispensable role, the significance of curtailing in-person consultations, and the imperative of following rigorous guidelines in regions with heightened COVID-19 prevalence. Additionally, the report delves into vaccination approaches for children with kidney issues, highlighting that the choice of vaccine is often governed by regional accessibility and policy frameworks, rather than a universal preference. A notable observation is the potential correlation between COVID-19 vaccines and specific kidney disorders. However, establishing a direct causal link remains elusive. In summary, our research accentuates the critical need for specialized pediatric kidney care during global health crises and reaffirms the continuous research imperative, especially regarding vaccination ramifications.

Worldwide, India ranks number 2 and 3 for COVID-19 burden and absolute transplant numbers, respectively. Here, we summarized our single and multicenter Indian studies on solid-organ transplant during the COVID-19 pandemic. During the pandemic, solid-organ transplants declined 40% to 50%. The mortality rate in COVID-19-positive kidney transplant recipients (11.6%) was lower in India compared with the developed world during the first wave and lower compared with maintenance hemodialysis patients (13% to 38%) but significantly higher compared with the nonimmunosuppressed general population (1% to 3%) in India. We contributed to National Organ and Tissue Transplant Organization transplant-related guidelines to increase safety and access to solid-organ transplant. We reported the safety and feasibility of remdesivir (n = 57) and convalescent plasma therapy (n = 10) in kidney transplant recipients. We reported 100% patient and graft survival without any complications related to COVID-19 in a large cohort of kidney transplant recipients who recovered from COVID-19 (n = 372) and a large cohort of kidney transplant recipients of living donors (n = 31) who recovered from COVID-19 without any change in induction and maintenance immunosuppression. COVID-19 disease severity and mortality in the second episode (reoccurring infection) was higher (46%) compared with the first episode (11.6%). There was 4.4% incidence of COVID-19-associated mucormycosis in kidney transplant recipients with mortality of 46% in the second wave. We reported COVID-19 vaccine safety with suboptimal efficacy in kidney transplant recipients and dialysis patients compared with the general population. Our report suggested that transplant with carefully selected COVID-19-recovered donors and patients may be feasible and safe, at least over the short term. Continued research is needed on vaccine efficacy, booster doses, and long-term follow up sequelae.

Maintenance hemodialysis (MHD) patients face disadvantages with higher risk of acquiring SARS-CoV-2 infection, atypical manifestations, and associated multiple comorbidities. We describe patients' outcomes with symptomatic COVID-19 on MHD in a large cohort of patients from India.

Data were collected prospectively from hemodialysis units in 11 public and private hospitals between March 15, 2020, and July 31, 2020. The survival determinants were analyzed using stepwise backward elimination cox-regression analysis.

Of the 263 total patients (mean age 51.76 ± 13.63 years and males 173) on MHD with symptomatic COVID-19, 35 (13.3%) died. Those who died were older (p = 0.01), had higher frequency of diabetic kidney disease (p = 0.001), comorbidities (p = 0.04), and severe COVID-19 (p = 0.001). Mortality was higher among patients on twice-weekly MHD than thrice-weekly (p = 0.001) and dialysis through central venous catheter (CVC) as compared to arteriovenous fistula (p = 0.001). On multivariate analysis, CVC use (HR 2.53, 95% CI 1.26-5.07, p = 0.009), disease severity (HR = 3.54, 95% CI 1.52-8.26, p = 0.003), and noninvasive ventilatory support (HR 0.59, 95% CI 0.25-0.99, p = 0.049) had significant effect on mortality.

The adjusted mortality risk of COVID-19 in MHD patients is high in patients associated with severe COVID-19 and patients having CVC as vascular access.

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.

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.

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.

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.
