Retrospective study evaluates diagnostic potential of inflammatory markers in peritonitis among PD patients, indicating new adjunctive tools.

This study aims to assess nutritional and inflammatory markers as potential diagnostic tools for peritonitis in peritoneal dialysis patients.
Retrospective analysis of 132 peritoneal dialysis patients.
Comparison between 83 patients with confirmed peritonitis and 49 without.
Evaluation of hematological, inflammatory, and nutritional indicators.
Multivariate logistic regression for identifying risk and protective factors.
ROC analysis to assess the diagnostic performance of various markers.
Peritonitis group showed higher PAR, NLR, MLR, and SIRI but lower levels of hemoglobin and albumin.
Hemoglobin and albumin are identified as protective factors, while CRP is a risk factor.
Combined model (PAR/NLR/MLR/SIRI) achieved an AUC of 0.798, indicating good diagnostic potential.
