We present the first case report of peritoneal dialysis (PD)-associated peritonitis due to , with the same pathogen detected in her caregiver's tinea capitis. This confirms that touch contamination from the caregiver's infection was the primary source of this rare organism. The species of pathogen causing peritonitis and her caregiver's scalp lesions were identified by DNA barcoding. The patient responded well to timely PD catheter removal and a 2-week course of systemic amphotericin B deoxycholate. Preventive strategies should prioritize hygiene practices, including maintaining adequate personal hygiene and practicing thorough hand washing, to mitigate the risk of touch contamination and subsequent infection with fungal pathogens.

Review
Serratia marcescens, as a Gram-negative opportunistic pathogen, is a rare cause of peritonitis and has worse clinical outcomes than Gram-positive peritonitis. In this case report, we describe a case of Serratia marcescens associated peritonitis that was successfully cured without catheter removal. A 40-year-old male patient with peritoneal dialysis who worked in the catering industry was admitted to the hospital for 16 hours after the discovery of cloudy peritoneal dialysate and abdominal pain. Ceftazidime and cefazolin sodium were immediately given intravenously as an empirical antibiotic regimen. After detecting Serratia marcescens in the peritoneal diasate culture, the treatment was switched to ceftazidime and levofloxacin. The routine examination of peritoneal dialysate showed a significant decrease in white blood cells, the peritoneal dialysate became clear, and the peritoneal dialysis catheter was retained. The patient was treated for 2 weeks and treated with oral antibiotics for 1 week. It is necessary to further strengthen the hygiene of work environment to prevent Serratia marcescens infection in peritoneal dialysis patients. We recommend that patients with Serratia marcescens associated peritonitis should be treated with a combination of antibiotics as early as possible empirically, and at the same time, the peritoneal dialysis fluid culture should be improved, and the antibiotic regimen should be timely adjusted according to the drug sensitivity results. For patients with clinical symptoms for more than 3 days, considering the strong virulence of Serratia marcescens, whether to use meropenem directly or not can provide a reference for clinical decision-making. Further clinical studies are needed to achieve more precise anti-infective treatment.

BACKGROUND
Infection with SARS-CoV-2 in high-risk groups such as kidney transplant and dialysis patients is shown to be associated with a more serious course of the disease. Four years after the start of the COVID-19 pandemic, crucial knowledge on the immune responses in these patient groups is still lacking. Therefore, this study aimed at investigating the humoral immune response after a SARS-CoV-2 infection compared to vaccination as well as the evolution of immunoglobulins over time.
METHODS
Kidney transplant recipients, patients on haemodialysis or on peritoneal dialysis and healthy controls were included in this longitudinal multicenter study. SARS-CoV-2 anti-RBD, anti-NP and anti-S1S2 immunoglobulin G (IgG) and A (IgA) as well as the neutralizing antibody capacity were measured.
RESULTS
Kidney transplant recipients had a significantly better humoral response to SARS-CoV-2 after infection (86.4%) than after a two-dose mRNA vaccination (55.8%) while seroconversion was comparable in patients on haemodialysis after infection (95.8%) versus vaccination (89.4%). In individuals without prior COVID-19, the IgG levels after vaccination were significantly lower in kidney transplant recipients when compared to all other groups. However, the IgA titres remained the highest in this patient group at each time point, both after infection and vaccination. A history COVID-19 was associated with higher antibody levels after double-dose vaccination in all patient categories and, while decreasing, titres remained high six months after double-dose vaccination.
CONCLUSION
Kidney transplant recipients had a more robust humoral response to SARS-CoV-2 following infection compared to a two-dose mRNA vaccination, while patients on haemodialysis exhibited comparable seroconversion rates. Notably, individuals with prior COVID-19 exhibited higher IgG levels in response to vaccination. Hybrid immunity is thus the best possible defence against severe COVID-19 disease and seems also to hold up for these populations. Next, it is not clear whether the higher IgA levels in the kidney transplant recipients is beneficial for neutralizing SARS-CoV-2 or if it is a sign of disease severity.

Peritoneal fibrosis, a common complication observed in long-term peritoneal dialysis patients, can gradually lead to ultrafiltration failure and the development of encapsulating peritoneal sclerosis. Although mechanisms of peritoneal fibrosis have been proposed, effective therapeutic options are unsatisfactory. Recently, several tyrosine kinase inhibitors have proven to be anti-fibrosis in rodent models. To assess the potential therapeutic effects of tyrosine kinase inhibitors on peritoneal fibrosis in the larger animal model, a novel porcine model of peritoneal fibrosis induced by 40 mM methylglyoxal in 2.5 % dialysate was established, and two different doses (20 mg/kg and 30 mg/kg) of sorafenib were given orally to evaluate their therapeutic efficacy in this study. Our results showed that sorafenib effectively reduced adhesions between peritoneal organs and significantly diminished the thickening of both the parietal and visceral peritoneum. Angiogenesis, vascular endothelial growth factor A production, myofibroblast infiltration, and decreased endothelial glycocalyx resulting from dialysate and methylglyoxal stimulations were also alleviated with sorafenib. However, therapeutic efficacy in ameliorating loss of mesothelial cells, restoring decreased ultrafiltration volume, and improving elevated small solutes transport rates was limited. In conclusion, this study demonstrated that sorafenib could potentially be used for peritoneal fibrosis treatment, but applying sorafenib alone might not be sufficient to fully rescue methylglyoxal-induced peritoneal defects.

Spontaneous renal cyst hemorrhage is one of the clinical emergencies in peritoneal dialysis (PD) patients and is potentially life-threatening. The main complaints are sudden low back pain, paleness, and hypotensive shock with or without vomiting or fever. In contrast to inherited polycystic kidney disease, acquired cystic kidney disease (ACKD) secondary to chronic kidney disease is easily overlooked or delayed in clinical diagnosis and treatment, leading to severe clinical outcomes. We report three patients with spontaneous hemorrhage of ACKD in the peritoneal dialysis center at Peking University First Hospital. The common features are as follows, long history of dialysis, mild to severe low back pain, decrease in hemoglobulin, negative PD solutions, diagnosis established through computed tomography (CT), and continuing PD during treatment of ACKD hemorrhage. Treatments vary from conservative to unilaterally selective renal artery embolization. In this study, ACKD morbidity was investigated in PD patients. A total of 316 patients who had an abdominal ultrasound, CT, or magnetic resonance imaging (MRI) in the past 1 year were enrolled. Among them, 103 cases (32.9%) met the diagnostic criteria of ACKD. The morbidity rates were 27.5%, 37.8%, 43.8%, 59.1%, and 88.6%, when the dialysis history ranged from ≤3, >3 & ≤5, >5 & ≤7, >7 & ≤9, >9 years, respectively, showing a increasing trend. Most ACKD hemorrhages could be healed and got an acceptable prognosis after treatment, including rest, blood transfusion, selective renal artery embolization, or nephrectomy. We summarize the risk factors, including a long history of dialysis, anticoagulation or antiplatelet, and inflammation or stones of the urinary system, but with no difference in initial kidney diseases and gender. ACKD hemorrhage mainly includes intracapsular hemorrhage, cyst rupture, and spontaneous retroperitoneal hemorrhage. In addition, we also recommend an adaptive process for spontaneous kidney hemorrhage of diagnosis and treatment in peritoneal dialysis patients. The significance of these cases lies in the fact that patients with ACKD are potentially associated with complications such as cyst hemorrhage and malignancy. Thus, peritoneal dialysis physicians should place great importance on the surveillance of ACKD.

BACKGROUND
Nutrients are crucial for dialysis patients, especially elderly patients. Nutrition-related complications in dialysis patients are often closely related to cardiovascular aging. However, we know little about the effect of different nutrients on the commonly used outcome predictor, health-related quality of life (HRQOL). Therefore, this study investigated the associations between different nutrients and HRQOL among dialysis patients.
METHODS
A cross-sectional study was conducted on 123 dialysis adults at multiple dialysis centers. The Short Form-36 Health Survey (SF-36) assesses HRQOL. Modified quantitative subjective global assessment (MQSGA) evaluates nutritional status. A 3-day dietary record evaluated nutrient intakes.
RESULTS
Among the 123 participants, 79 received hemodialysis (HD), and 44 were on peritoneal dialysis (PD). Patients with PD had a higher SF-36 score than HD (525 ± 136 vs. 375 ± 179, < 0.001). A negative association between nutrition status and HRQOL was observed in HD (regression coefficient = -17.4, < 0.001) but not in PD ( = -12.3, = 0.07). For HD patients, the nutrition status was negatively correlated with intakes of carbohydrates, fiber, selenium, copper, and Manganese ( = -0.02, = 0.032; = -0.3, = 0.031; = -0.1, = 0.006; = -2.3, = 0.025; = -1.3, = 0.003, respectively). Their HRQOL was positively associated with calories, fat, niacin, and vitamin E ( = 2.19, = 0.035; = 2.4, = 0.043; = 8.5, = 0.044; = 6.9, = 0.017, respectively). Conversely, for patients with PD, only vitamin B2 was found to be adversely correlated with their nutritional status ( = -5.2, = 0.037), and increased intakes of vitamin A, vitamin C and fiber ( = 0.1, = 0.031; = 0.8, = 0.028; = 15.8, = 0.045, respectively) were associated with a better HRQOL.
CONCLUSIONS
The nutritional intake of PD patients and HD patients affects their quality of life differently. Macronutrients significantly impact HRQOL in HD patients, while vitamins have a more substantial impact on PD patients.

Frontiers in Medicine 2024Brucella infection is uncommon among peritoneal dialysis (PD) patients in non-endemic areas, and the occurrence of both peritonitis and abdominal aortitis is rare.
BACKGROUND
Brucella infection is uncommon among peritoneal dialysis (PD) patients in non-endemic areas, and the occurrence of both peritonitis and abdominal aortitis is rare.
CASE PRESENTATION
In December 2023, a 63-year-old male patient undergoing PD was admitted to Shaoxing Second Hospital due to fever, abdominal pain, and cloudy dialysate. Upon physical examination, diffuse mild abdominal pain and tenderness were observed. Subsequent investigation into the patient's medical history revealed consumption of freshly slaughtered lamb from local farmers 3 days prior to the onset of symptoms. Various diagnostic tests, including routine blood tests, procalcitonin levels, and PD fluid analysis, indicated the presence of infection. Abdominal computed tomography (CT) imaging revealed localized lumen widening of the abdominal aorta with surrounding exudative changes. On the sixth day in the hospital, blood and PD fluid cultures confirmed infection. The patient was diagnosed with brucella-associated peritonitis and aortitis. Treatment was adjusted to include rifampin and doxycycline for 6 weeks, and the decision was made to keep the PD catheter. Remarkably, the patient exhibited resolution of peritonitis and abdominal aortitis within the initial week of the adjusted treatment. Currently, the patient continues to receive ongoing clinical monitoring.
CONCLUSION
Brucella is rare but can cause PD-associated peritonitis and arteritis. Prompt diagnosis and treatment can lead to a good outcome in PD patients. Dual therapy is effective, but the need for catheter removal is unclear. Consider international guidelines and patient factors when deciding on catheter removal.

RATIONALE & OBJECTIVE
Developing strategies to improve home dialysis use requires a comprehensive understanding of barriers. We sought to identify the most important barriers to home dialysis use from the perspective of patients, care partners, and providers.
STUDY DESIGN
This is a convergent parallel mixed-methods study.
SETTING & PARTICIPANTS
We convened a seven-member advisory board of patients, care partners, and providers who collectively developed lists of major patient/care partner-perceived barriers and provider-perceived barriers to home dialysis. We used these lists to develop a survey that was distributed to patients, care partners, and providers-through the American Association of Kidney Patients and the National Kidney Foundation. The surveys asked participants to: 1) rank their top three major barriers (quantitative); and 2) describe barriers to home dialysis (qualitative).
ANALYTICAL APPROACH
We compiled a list of the top three patient/care partner-perceived and top three provider-perceived barriers (quantitative) and conducted a directed content analysis of open-ended survey responses (qualitative).
RESULTS
There were 522 complete responses (233 providers; 289 patients/care partners). The top three patient/care partner-perceived barriers were: fear of performing home dialysis; lack of space; and the need for home-based support. The top three provider-perceived barriers were: poor patient education; limited mechanisms for home-based support staff, mental health, and education; and lack of experienced staff. We identified nine themes through qualitative analysis: limited education; financial disincentives; limited resources; high burden of care; built environment/structure of care delivery that favor in-center hemodialysis; fear and isolation; perceptions of inequities in access to home dialysis; provider perspectives about patients; and patient/provider resiliency.
LIMITATIONS
This was an online survey that is subject to non-response bias.
CONCLUSIONS
The top three barriers to home dialysis for patient/care partners and providers incompletely overlap, suggesting the need for diverse strategies that simultaneously address patient-perceived barriers at home and provider-perceived barriers in the clinic.
