Introduction: Coronavirus disease 2019 (COVID-19) is an outbreak due to SARS-CoV-2, declared by the World Health Organization (WHO) as a global pandemic in March 2020. Patients with underlying diseases, such as those with end-stage kidney disease (ESKD) on dialysis, are at greater risk. Objectives: The aim of our study to assess the outbreak and impact of COVID-19 on dialysis patients. Patients and Methods: Our study prospectively assessed and followed 442 patients with ESKD undergoing dialysis [390 patients on maintenance hemodialysis (HD) and 52 patients on peritoneal dialysis (PD)] for outbreak and impact of COVID-19 on these patients during the period from April 22, 2020 until March 23, 2021 in Al Khezam dialysis center, Kuwait.

Impact of COVID-19 infection on the dialysis population prospective, observational, nationwide study
International Urology and Nephrology
Introduction Hemodialysis (HD) patients are at increased risk of severe COVID-19 infection but infection rates vary. Our objectives are to describe COVID-19 positive HD patients’ characteristics, infection rates, and factors associated with mortality in HD COVID-19 cases in Kuwait. Methods Data on demographics, comorbidities, and treatments received, as well as mortality for HD patients admitted to hospitals for COVID-19, from 1/March to 31/July 2020, prospectively collected and analyzed. Results A total of 141 infected HD patients were admitted (Mean age 58 ± 16.1; Males 56%), representing 7% of the total HD population and 0.2% of all COVID-19 cases during the study period. Of those 141 infected HD patients, 27 (19%) died, and this represents 6% of total COVID-19-related mortality and 27% of the total HD mortality. In contrast, total covid-19-related mortality of all positive cases was only 0.7%, and total HD mortality during the study period was only 5%. COVID-19-positive HD patie...
Dialysis During the COVID-19 Pandemic: Experiences from 4 Dialysis Centers in Iran
Nephro-Urology Monthly
Background: Despite all of the research on the risk factors for severe COVID-19, there are still many unknowns about the course of COVID-19 in various populations. Inevitable exposure of dialysis patients, one of the more vulnerable groups for infectious diseases, to COVID-19 concerns many researchers. Furthermore, studies on the mortality rate and risk factors regarding dialysis patients are somewhat inconsistent. Also, it has been suggested that factors such as ethnicity can contribute to that matter. Objectives: We aimed to evaluate the mortality rate of dialysis patients who contracted COVID-19 in the Iranian population. Methods: In this cross-sectional study, we presented the experiences of 4 dialysis centers with a total of 309 dialysis patients (Tehran, Iran) during the COVID-19 pandemic to assess the mortality rate and associated risk factors. Results: Among 309 dialysis patients, 58 patients contracted the disease, and the total mortality rate in this study was 41%. It was ...

Aim: Data published on COVID-19 in the Filipino population, particularly those with end stage kidney disease (ESKD) are still lacking. Methods: We performed a retrospective, observational study of 68 ESKD patients admitted with COVID-19 infection at a tertiary hospital in Metro Manila, Philippines from April 1, 2020 to July 31, 2020. We compared the clinical features, baseline laboratory data, treatment strategies and short-term outcomes between those who survived and those who died. We also determined the risk factors associated with mortality from COVID-19. Results: Mean age was 54.5 years old, 66% were male. All patients admitted were on maintenance hemodialysis (HD). The most common presenting symptoms were dyspnea (57%), fever (47%) and cough (38%). There was an equal number of patients on high flow nasal cannula (17.7%) and invasive mechanical ventilation (17.7%). ICU admission was required in 17.7% of the cohort. In-hospital death occurred in 25% of the patients. Admission PaO 2 /FiO 2 (PF) ratios (162 ± 134 versus 356 ± 181; p=0.0009) were lower, and procalcitonin (6.07 ± 10.5ng/mL versus 0.73 ± 3.61 ng/mL; p=0.02), lactate dehydrogenase (396 ± 274U/L versus 282 ± 148 U/L; p=0.03), and white blood cell counts (10 ± 7.3 x 10 9 /L versus 6.3 ± 4.2 x 10 9 /L; p= 0.0039) were significantly higher among those who died compared to those who survived. After adjusting for confounders, only low PF ratio (HR 1.01 for every unit decrease, 95% CI 1-1.01) and need for ventilation (HR 6.45, 95% CI 1.16-35.97) conferred a significant risk for in-hospital mortality. Conclusion: Short-term, in-hospital mortality is high among patients on chronic hemodialysis admitted for COVID-19 infection. They present similarly with the general population. Low PF ratio on admission and need for ventilation are independent risk factors for inhospital mortality.
Strategies for Management of Peritoneal Dialysis Patients in Singapore during COVID-19 Pandemic
Annals of the Academy of Medicine, Singapore, 2020
Peritoneal dialysis (PD) is the only well-established home-based dialysis therapy in Singapore. As it is a home-based modality, PD should be considered as a preferred mode of kidney replacement therapy (KRT) for patients with kidney failure during this COVID-19 pandemic as it avoids frequent visits to hospitals and/or satellite dialysis centres. The highly infectious nature of this virus has led to the implementation of the Disease Outbreak Response System Condition orange status in Singapore since early February 2020. This paper summarises the strategies for management of several aspects of PD in Singapore during this COVID-19 pandemic, including PD catheter insertion, PD training, home visit and assisted PD, outpatient PD clinic, inpatient management of PD patients with or without COVID-19 infection, PD as KRT for COVID-19 patients with acute kidney injury, management of common complications in PD (peritonitis and fluid overload), and management of PD inventory.

COVID-19 in patients undergoing long-term dialysis in Ontario
Canadian Medical Association Journal
populous province, almost 41 000 people had tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19), 1 which represented 0.3% of the provincial population. Close to 2800 people had died, a case fatality rate of 6.8%. 2 Patients undergoing dialysis have high rates of comorbid conditions, are often older adults, have varying degrees of immunosuppression and are more likely to reside in long-term care, which puts them at risk of both acquiring SARS-CoV-2 and developing complicated disease. 3,4 Furthermore, in Ontario, those who receive in-centre hemodialysis typically have 3 treatments per week in outpatient units located in or affiliated with hospitals, and the consequent inability to fully selfisolate means that patients undergoing hemodialysis likely have an even higher risk of SARS-CoV-2 infection. 3,4 Recent studies support this but do not compare infection rates with those in the local population of patients not undergoing dialysis. 5-10 Several studies have reported SARS-CoV-2 infection in single or multicentre cohorts of patients undergoing dialysis, 5-10 but we are unaware of any that have identified risk factors for infection at the level of a large region. Some studies have found that patients with SARS-CoV-2 infection who are undergoing dialysis are at high risk of severe illness and death. 6-10 Methods Study setting Ontario has a population of about 14.5 million. More than 12 000 people receive long-term dialysis, with about 74% receiving in-centre hemodialysis and 26% home dialysis, which comprises 21% peri toneal dialysis and 5% home hemodialysis. All dialysis in Ontario is funded by a single payer-the provincial government-operating through the Ontario Renal Network (ORN), a provincial agency that funds and manages services for patients with chronic kidney disease within 27 Renal Programs, which provide home dialysis services and operate more than 100 in-centre hemodialysis units. 11 The latter vary in size from 3 to 60 hemodialysis stations.

Much has now been learned about the coronavirus disease 2019 (COVID-19) in the general population, but data for hemodialysis (HD) patients are limited. This is the first study of COVID-19 disease in patients undergoing maintenance HD in Pakistan. We studied the epidemiological, clinical, laboratory, radiological characteristics, and outcomes of a cohort of HD patients that contracted COVID-19 in our HD center from the first confirmed case on May 12, 2020, until September 9, 2020. Out of the total 423 patients being dialyzed in our center, 87 were suspected and 50 (11.8%) were confirmed for COVID-19. Male:Female ratio was nearly equal. The median age was 59.5 ± 9.99 years. Most patients developed mild disease. The most common symptoms were fever (82%). Ten (20%) had patchy bilateral opacity (ground-glass opacity) on the chest radiograph. Major complications were lymphocytopenia (36%), thrombocytopenia (30%), pneumonia (28%), and septic shock (6%). Eleven (22%) patients were hospitalized. Five required mechanical ventilation. Ten (20%) patients died. The relative risk of death with COVID-19 in HD patient was 1.46 with 95% confidence interval 1.15-1.84, (P = 0.003). The patients aged ≥60 years had 4.3 times more severe disease (P = 0.044) and died 3.3 times (P = 0.164) more than patients aged <60 years. HD patients have a high susceptibility to COVID-19 compared to the general population with an increased mortality rate and prolonged recovery time. Patients with age >60 years, female gender, diabetics, and those presented with more severe symptoms and laboratory parameters, had a higher fatal outcome.
