Aim:
Peritoneal dialysis (PD) patients have different peritoneal membrane permeability (transport) characteristics. High peritoneal membrane permeability is associated with increased mortality risk in the patient population. In this study, we aimed to investigate possible risk factor(s) related to high peritoneal membrane permeability.
Patients And Method:
The study included 475 PD patients (46.1 ± 14.5 years of mean age; 198 female and 277 male). The patients were divided two groups according to peritoneal equilibration test (PET) result: high-permeability group (high and high-average) and low- permeability group (low-average and low).
Results:
In both the univariate and multivariate logistic regression analyses, it was found that diabetes mellitus and hypoalbuminemia was significantly associated with high peritoneal membrane permeability [relative risk (RR): 1.90, 95% confidence interval (CI): 1.26-2.86, p: 0.002 and RR: 2.14, 95% CI: 1.44-3.18, p<0.001, respectively].
Conclusion:
Diabetes mellitus and hypoalbuminemia were closely associated with high peritoneal membrane permeability. Diabetic patients had 1.9 times the likelihood of having high permeability. However, the relationship between hypoalbuminemia and high peritoneal permeability appears to be a result rather than cause.

Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
