Abstract
BACKGROUND Reports on COVID-19 in peritoneal dialysis (PD) patients are scarce in China. This study aimed to describe the characteristics and outcomes of PD patients with COVID-19 after China abandoned the 'zero-COVID' policy. METHODS This single-centre retrospective study included patients receiving PD who underwent testing for COVID-19 infections between 7 December 2022 and 7 January 2023. Outcomes of interest included factors associated with positive COVID-19 testing result and clinical outcomes including COVID-19-related hospitalisation and severe COVID-19, which were analysed using logistic regression analyses. RESULTS A total of 349 PD patients (male 53.6%, age 49 ± 13 years old) were included, and 235 patients (67.3%) were infected. There were no significant differences between COVID-19 and non-COVID-19 patients other than higher proportion of vaccinated patients and slow transporters in the patients who tested positive for COVID-19 (44.7% vs. 28.1%, p = 0.003; 8.7% vs. 1.8%, p = 0.03, respectively). Multivariate analysis showed COVID-19 was associated with vaccination (odds ratio (OR): 1.71, 95% confidence interval (CI): 1.02-2.86) and slow transport type (compared with average transport type, OR: 4.52, 95% CI: 1.01-20.21). Among the patients with infection, 38 (16.2%) patients were hospitalised, 18 (7.7%) patients had severe disease and 9 (3.8%) patients died. In multivariate logistic analysis, both age (OR: 1.04, 95% CI: 1.01-1.07; OR: 1.06, 95% CI: 1.02-1.11) and hyponatremia (OR: 5.44, 95% CI: 1.63-18.13; OR: 6.50, 95% CI: 1.77-23.85) were independent risk factors for COVID-19-related hospitalisation and severe disease. CONCLUSIONS Although vaccinated patients were more likely to have tested positive for COVID-19 infection, they appeared to have less severe infection and less need for hospitalisation. Patients who were older with a history of hyponatremia were more likely to experience adverse outcomes from COVID-19.

Abstract
INTRODUCTION During the height of the coronavirus disease-19 (COVID-19) pandemic, some renal replacement therapy (RRT) modalities were insufficient, forcing medical centers to diversify the RRT modalities offered. In this study, we reported the outcomes of chronic peritoneal dialysis (PD) patients and acute PD in critically ill patients during COVID-19 pandemic in a tertiary care medical center in Mexico. METHODS This descriptive, longitudinal, observational, retrospective study included 47 adult patients with atypical pneumonia in a tertiary care medical center in Mexico during the first and second waves of the COVID-19 pandemic. Chronic PD patients and PD incident patients due to acute kidney injury (AKI) were included. RESULTS Forty-seven patients were studied (29 chronic PD patients and 18 incident PD patients due to AKI); median age was 59 (48-68) years; 63.8% were men. The ultrafiltrate volume per day was 815 (596.1-1,193.2) mL. Overall mortality was 61.7%, 55.2% in chronic PD patients, and 72.2% in PD incident patients due to AKI. A higher Sequential Organ Failure Assessment (SOFA) score, the need for mechanical ventilation at admission, and the requirement for vasopressors were predictors for mortality (p < 0.01). CONCLUSION In low- and lower-middle-income countries, PD was a valid alternative for RRT during the COVID-19 pandemic. In AKI patients, PD can correct hyperkalemia, acidosis, uremia, and volume overload; however, there was higher mortality in PD incident patients due to AKI. The main risk factors for mortality were a high SOFA score at admission, the need for invasive mechanical ventilation, and the requirement for vasopressors.

Abstract
The COVID-19 pandemic exerted complex pressures on the nephrology community. Despite multiple prior reviews on acute peritoneal dialysis during the pandemic, the effects of COVID-19 on maintenance peritoneal dialysis patients remain underexamined. This review synthesizes and reports findings from 29 total cases of chronic peritoneal dialysis patients with COVID-19, encompassing 3 case reports, 13 case series, and 13 cohort studies. When available, data for patients with COVID-19 on maintenance hemodialysis are also discussed. Finally, we present a chronological timeline of evidence regarding the presence of SARS-CoV-2 in spent peritoneal dialysate and explore trends in telehealth as they relate to peritoneal dialysis patients during the pandemic. We conclude that the COVID-19 pandemic has underscored the efficacy, flexibility, and utility of peritoneal dialysis.

Abstract
BACKGROUND AND OBJECTIVE COVID-19 infection poses a special challenge to patients with dialysis patients. The purpose of this study was to evaluate the clinical manifestations of dialysis patients with COVID-19 and the protective effect of the vaccine. METHODS We included 41 studies based on big data, mainly analyzing the clinical symptoms of dialysis patients with COVID-19, the proportion of severe patients before and after vaccination, and the humoral reaction of vaccine in the body. RESULTS 6.1% to 35.7% of dialysis patients with COVID-19 developed respiratory distress symptoms and needed to be admitted to an intensive care unit for mechanical ventilation. The incidence and mortality of COVID-19 in dialysis patients before vaccination were 5.5% and 1.1%, respectively, and decreased to 4.5% and 0.6% in breakthrough infected patients. There was no statistical difference in serum conversion rates between dialysis patients and healthy controls, but the neutralizing antibody titer in the control group was 1922 (IQR 533 to 3186) AU/mL, and the neutralizing antibody titer in dialysis patients significantly decreased to 367 (IQR 171 to 1650) AU/mL (P=0.046). CONCLUSIONS Dialysis is associated with an increased risk of severe COVID-19, and generally has a poor seroconversion response to vaccines. It also confirms the protective effect of vaccines on high-risk populations such as dialysis.

Abstract
BACKGROUND Maintenance hemodialysis (MHD) is a commonly used renal replacement therapy for end-stage renal disease patients. MHD patients have undergone multiple physiological stressors, which may cause physical problems and affect their mental health; however, few qualitative studies have been done on the mental health of MHD patients. Such qualitative research becomes the basis for further quantitative research and is critical to validating its results. Therefore, the current qualitative study used a semi-structured interview format, and aimed to explore the mental health and its influencing factors of MHD patients who are not receiving intervention treatment to determine how best to ameliorate their mental health. METHODS Based on the application of Grounded Theory, semi-structured face-to-face interviews were conducted with 35 MHD patients, following consolidated criteria for reporting qualitative studies (COREQ) guidelines. Two indicators (emotional state and well-being) were used to assess MHD patients' mental health. All interviews were recorded, after which two researchers independently performed data analyses using NVivo. RESULTS Acceptance of disease, complications, stress and coping styles, and social support were found to be the influencing factors of MHD patients' mental health. High acceptance of disease, healthy coping styles, and high social support were positively correlated with mental health. In contrast, low acceptance of disease, multiple complications, increased stress, and unhealthy coping styles were negatively correlated with mental health. CONCLUSION One's acceptance of the disease played a more significant role than other factors in affecting MHD patients' mental health.

Abstract
Patients with end-stage renal disease (ESRD) often will ultimately require dialysis to survive. One type of dialysis is peritoneal dialysis (PD), which utilizes the vessel-rich peritoneum as a semi-permeable membrane to filter blood. In order to perform PD, a tunneled catheter must be placed through the abdominal wall and into the peritoneal space, with ideal positioning of the catheter within the most dependent portion of the pelvis, represented by the rectouterine or rectovesical space in women and men, respectively. There are several approaches to PD catheter insertion, including open surgical, laparoscopic surgical, blind percutaneous, and image-guided with the use of fluoroscopy techniques. Interventional radiology (through the use of image-guided percutaneous techniques) is an infrequently utilized resource to place PD catheters, and offers real-time imaging confirmation of catheter positioning with similar outcomes to more invasive surgical catheter insertion approaches. Although the vast majority of dialysis patients receive hemodialysis instead of peritoneal dialysis in the United States, some countries have moved towards a "Peritoneal Dialysis First" initiative, prioritizing initial PD, as it is less burdensome on healthcare facilities as it can be performed at home. In addition, the outbreak of the COVID-19 pandemic has produced shortages of medical supplies and delays in care delivery worldwide, while simultaneously generating a shift away from in-person medical visits and appointments. This shift may be met with more frequent utilization of imaged-guided PD catheter placement, reserving surgical and laparoscopic placement for complex patients who may require omental periprocedural revisions. This literature review outlines a brief history of PD, the various techniques of PD catheter insertion, patient selection criteria, and new COVID-19 considerations, in anticipation for the increased demand for PD in the United States.

Abstract
The COVID-19 pandemic has transformed the health landscape by hampering the management of patients with chronic diseases. Providing optimal healthcare has become a critical issue, especially for patients with end-stage renal disease (ESRD) receiving in-center dialysis. Peritoneal Dialysis (PD) has the advantage of being a home-based therapy. Several papers about COVID-19 in the chronic kidney disease (CKD) population have been published, but few studies focused on the PD population, with limited case series. In this paper, we share our strategy for managing PD patients during the pandemic and describe the characteristics of 24 episodes of COVID-19 that occurred in our PD patients. Also, we report the impact of the pandemic on different outcomes and discuss the challenges of renal replacement therapy (RRT) in the time of COVID-19 and the advantages of PD. During the period from December 2019 to September 2021, 127 patients received PD in our center. Among them, we recorded 24 episodes of COVID-19 that occurred in 20 patients, corresponding to an incidence of 8.4 per 1000 patient-months. None of the 20 patients with COVID-19 were vaccinated and there was a significant male gender predominance in the COVID-19 group compared to the non-COVID-19 group. The prevalence of diabetic nephropathy and primary glomerulonephritis were also significantly higher in the COVID-19 group. The revealing symptoms were asthenia, dry cough, and the deterioration of general conditions in 100%, 75%, and 63% of the patients, respectively. A biological inflammatory syndrome was found in 30% of the patients. Chest computed tomography (CT) scan, performed in 5 patients, showed features of COVID pneumonia with an average extent of damage of 55%. The rate of patients starting PD during the study period was comparable to that before the pandemic. Furthermore, we did not find a significant difference between the infected and the non-infected groups regarding the incidence of peritonitis, PD technique failure, and mortality (6.1 [0-1.46] vs 3.9 [0.15-0.64] deaths per 1000 patient-months. COVID-19 does not seem to have influenced the outcomes of our patients treated with PD even before the launch of mass immunization in our country. Thus, PD can be a great option for RRT in the era of the COVID-19 pandemic since many issues could be managed remotely to avoid regular hospital visits and contribute to maintaining social distancing, which is the cornerstone of breaking the chain of transmission of the novel virus.

Abstract
BackgroundThe fatality rates and factors associated with death from coronavirus disease 2019 (COVID-19) in hemodialysis patients have been extensively investigated. However, data on peritoneal dialysis (PD) patients remain scarce.Materials and methodsIn this nationwide cohort study, we assessed the 28-day COVID-19-related fatality rate in PD patients between August 2021 and July 2022 using data from the InCov19-PD registry. Predictors associated with death were evaluated using a multivariable Cox regression model. Changes in functional status before and during COVID-19 were also examined.ResultsA total of 1,487 eligible participants were evaluated. During the study period, 196 participants died within 28 days after COVID-19 diagnosis (case fatality rate: 13%). In a multivariable Cox regression model, an increased risk of death within 28 days after COVID-19 diagnosis among PD patients was independently associated with functional impairment during COVID-19 [adjusted hazard ratio (HR) 2.46, 95% confidence interval (CI) 1.59–3.81], SARS-CoV-2 infection with the Delta variant (HR 2.23, 95% CI 1.55–3.21), and the need for respiratory support (HR 7.13, 95% CI 3.74–13.57) (p < 0.01 for all). Conversely, the number of COVID-19 vaccines administered (HR 0.69, 95% CI 0.55–0.87; p = 0.001) and receiving corticosteroid therapy during COVID-19 (HR 0.72, 95% CI 0.54–0.97; p = 0.03) were associated with a decreased risk of death within 28 days after COVID-19 diagnosis. The number of functionally independent PD patients dropped from 94% at baseline to 63% during COVID-19 (p < 0.01).ConclusionsThe COVID-19-related 28-day fatality rate was high among PD patients. The predictors of COVID-19-related death in PD patients were similar to those in hemodialysis patients. During COVID-19, PD patients commonly experienced functional deterioration.

Abstract
Resumo Antecedentes: A incidência e a taxa de letalidade da síndrome respiratória aguda grave por coronavírus 2 relatadas em pacientes em diálise crônica são mais elevadas do que na população em geral. Procuramos estudar os desfechos após o diagnóstico da doença por coronavírus 2019 (COVID-19) em pacientes submetidos à hemodiálise crônica (HD) ou diálise peritoneal (DP) em um único centro no Brasil. Métodos: Dos 522 pacientes em diálise avaliados entre 1º de Março de 2020 e 1º de Outubro de 2021, aqueles que apresentaram sintomas ou tiveram histórico de contato próximo com pacientes com COVID-19 foram testados com reação em cadeia da polimerase de transcrição reversa por meio de amostras de esfregaços nasofaríngeos. Resultados: Dos 522 pacientes, 120 foram positivos para infecção por COVID-19, dos quais 86% estavam em HD e 14% no programa de DP. A incidência por 10.000 habitantes foi maior no grupo HD do que no grupo DP (2.423,5 vs. 1.752,5). A mortalidade por 10.000 habitantes (470,5 vs. 927,8) e a taxa de letalidade (19,4 vs. 52,9%, p = 0,005) foram mais elevadas no grupo DP. O grupo DP também apresentou uma maior necessidade de hospitalização, terapia intensiva e ventilação mecânica. Conclusões: Recomendamos cautela ao considerar estratégias de transferência de pacientes do programa de HD para o de DP a fim de minimizar o risco de COVID-19 para pacientes em HD.

Abstract
INTRODUCTION With the evolution of SARS-CoV-2 pandemic, it was believed to be a direct respiratory virus. But, its deleterious effects were observed on different body systems, including kidneys. AIM OF WORK In this review, we tried as much as we can to summarize what has been discussed in the literature about the relation between SARS-CoV-2 infection and kidneys since December, 2019. METHODS Each part of the review was assigned to one or two authors to search for relevant articles in three databases (Pubmed, Scopus and Google scholar) and collected data were summarized and revised by two independent researchers. CONCLUSION The complexity of COVID-19 pandemic and kidney could be attributed to the direct effect of SARS-CoV-2 infection on the kidneys, different clinical presentation, difficulties confronting dialysis patients, restrictions of the organ transplant programs, poor outcomes and bad prognosis in patients with known history of kidney diseases who got infected with SARS-CoV-2.

BACKGROUND The reported incidence and fatality rate of the severe acute respiratory syndrome coronavirus 2 in patients receiving chronic dialysis are higher than in the general population. We sought to study the outcomes following coronavirus disease 2019 (COVID-19) diagnosis in patients undergoing chronic hemodialysis (HD) or peritoneal dialysis (PD) in a single center in Brazil. METHODS Of the 522 patients on dialysis evaluated between March 1, 2020, and October 1, 2021, those presenting symptoms or with a history of close contact with COVID-19 patients were tested with reverse-transcription polymerase chain reaction of samples from nasopharyngeal swabs. RESULTS Of the 522 patients, 120 were positive for COVID-19 infection, of which 86% were on HD and 14% in the PD program. The incidence per 10,000 inhabitants was higher in the HD group than in the PD group (2,423.5 vs. 1,752.5). The mortality per 10,000 inhabitants (470.5 vs. 927.8) and the fatality rate (19.4 vs. 52.9%, p = 0.005) were higher in the PD group. The PD group also had a higher need for hospitalization, intensive care, and mechanical ventilation. CONCLUSIONS We advise caution when considering strategies to transfer patients from HD to the PD program to minimize the risk of COVID-19 for patients on HD.

Abstract
OBJECTIVE Peritoneal fibrosis (PF) ultimately causes ultrafiltration failure and peritoneal dialysis (PD) termination, but there are few effective therapies for it. Core fucosylation, which is catalyzed by α1,6-fucosyltransferase (Fut8) in mammals, may play a crucial role in PF development. This study aims to assess the effects of inhibiting core fucosylation of epidermal growth factor (EGF) receptor on PF rats. METHODS PF rats (established by 4.25% glucose dialysate) were treated with either an adenovirus-Fut8 short hairpin RNA (Fut8shRNA) or adenovirus-control. Masson's staining and net ultrafiltration were performed at week six. Fut8 level and core fucosylation of EGF receptor and collagen I in the peritoneal membrane were assessed, and EGF signaling was detected, including signal transducer and activator of transcription 3 (STAT3), nuclear factor kappa B (NF-κB) and their phosphorylation. Monocyte chemoattractant protein-1 (MCP-1) in peritoneal effluent was examined. RESULTS Fut8 was upregulated in PF rats but decreased after Fut8shRNA treatment. EGF and EGF receptor expression was upregulated in PF rats, while core fucosylation of EGF receptor decreased after Fut8shRNA treatment. Masson's staining results showed an increase in peritoneal thickness in PF rats but a decrease after Fut8shRNA treatment. Fut8shRNA treatment increased net ultrafiltration, reduced the expression of collagen I and MCP-1 compared to PF rats. Fut8shRNA treatment suppressed phosphorylation of STAT3 and NF-κB in the peritoneal membrane of PF rats. CONCLUSIONS Fut8shRNA treatment ameliorated the fibrotic changes in PF rats. A potential mechanism may be that Fut8shRNA treatment inactivated EGF signaling pathway by suppressing the phosphorylation of STAT3 and NF-κB.

Abstract
BACKGROUNDS The recent coronavirus disease 2019 (CO-VID-19) pandemic has placed worldwide health systems and hospitals under pressure, and so are the renal care models. This may be a unique opportunity to promote and expand alternative models of health-care delivery in patients undergoing renal replacement therapies. SUMMARY Despite the high risk of acquiring communicable diseases when undergoing in-centre treatments, only a small proportion of patients are currently being treated with home therapies. Recent data provided by the Italian Society of Nephrology (SIN), the REIN French Registry and the Wuhan Hemodialysis Quality Control Center clearly show that patients receiving hospital-based treatment have a 3- to 4-fold greater risk of infection, and a subsequent fatality proportion between 21 and 34%. On the other hand, home-based therapy can be managed remotely, there is little or no need for transport to and from the hospital, and it is less expensive. Besides, the digital revolution in health care with the development of virtual care systems can make home dialysis with telehealth a cost-effective solution for both patients and health-care providers. Such a transition would require specific training for physicians and health-care professionals and a functional re-organization of dialysis centres to improve the skills and expertise in caring for patients at home. CONCLUSION The need for more widespread home treatment is the main lesson learnt by nephrologists by the COVID-19 pandemic.
