Epidemiology data predict that by the year 2025, diabetes will affect about 380 million people worldwide with a significant increase in patients with chronic renal disease progressing to hemodialysis. Diabetes-related peripheral vascular disease is a major risk factor for vascular access failure in patients on extracorporeal hemodialysis. Although peritoneal dialysis is a valid option for diabetics, peritonitis is still a main complication for these patients. We report the case of a 71-year-old type 2 diabetes patient treated by subcutaneous insulin, undergoing automated peritoneal dialysis (APD) who developed peritonitis and bloodstream infection by Ochrobactrum anthropi (O. anthropi). The patient was initially shifted to continuous ambulatory peritoneal dialysis (CAPD) and treated with intraperitoneal cefotaxime and gentamicin. According to antibiogram, cefotaxime was discontinued but lasting gentamicin. Within 48 h from admission, clear peritoneal effluent was observed with reduction in white blood cells count from 580/mm³ 77.9% neutrophils to less than 10/mm³. Prompt regression of infection without catheter removal and no relapse after over 7-month follow-up allowed supposing that O. anthropi did not colonized peritoneal catheter. O. anthropi is an emerging cause of nosocomial infection in immunocompromised patients. Cases of such infection in patients undergoing CAPD and hemodialysis have been already described. However, this is the first reported case of O. anthropi in a patient undergoing APD.

Importance: People with kidney failure have a high risk of death and poor quality of life. Mortality risk prediction models may help them decide which form of treatment they prefer.
Objective: To systematically review the quality of existing mortality prediction models for people with kidney failure and assess whether they can be applied in clinical practice.
Mechanisms underlying the involvement of peritoneal macrophages in the pathogenesis and novel therapeutic strategies for dialysis-induced peritoneal fibrosis.

Long-term exposure of the peritoneum to peritoneal dialysate results in pathophysiological changes in the anatomical organization of the peritoneum and progressive development of peritoneal fibrosis. This leads to a decline in peritoneal function and ultrafiltration failure, ultimately necessitating the discontinuation of peritoneal dialysis, severely limiting the potential for long-term maintenance. Additionally, encapsulating peritoneal sclerosis, a serious consequence of peritoneal fibrosis, resulting in patients discontinuing PD and significant mortality.

Introduction: The objective of this study is to investigate the dynamic changes in serum albumin and ferritin as potential predictors for early-onset peritoneal dialysis-related peritonitis (PDRP) in patients undergoing peritoneal dialysis (PD).
Methods: This retrospective study included 215 patients with end-stage renal disease who initiated PD at Huadong Hospital. Patients were followed up to 24 months, during which episodes of PDRP were recorded.

Anorexia nervosa (AN) is an eating disorder characterized by restriction of energy intake leading to a significantly low body weight, and intense fear of gaining weight. Severe electrolyte changes such as hypokalemia and hypophosphatemia; and alterations in water metabolism such as hyponatremia and edema, can occur in patients with AN. Hypokalemia and chronic volume depletion may lead to acute kidney injury (AKI) and chronic kidney disease (CKD).

Purpose: To investigate the current status of medication adherence among peritoneal dialysis (PD) patients in a primary hospital and to explore the influencing factors of medication adherence among PD patients.
Methods: The author used the Chinese version of the Morisky Medication Compliance Scale to evaluate the medication compliance of 226 PD patients in a single centre. Univariate analysis and logistic regression were used to analyse the factors influencing medication compliance in patients.
