Correlation of arteriolar CLDN2 and mesothelial CLDN4, CLDN15 and PiT1 abundance with D/P creatinine and D/D0 glucose obtained from peritoneal equilibration test data in a subcohort of patients at the start of treatment and on chronic peritoneal dialysis. D/P Creatinine and D/D0 Glucose significantly correlated with CLDN2 in the arteriolar area, CLDN15 in the mesothelial area and D/D0 Glucose with CLDN4 (with D/P Creatinine p = 0.06, r = 0.50) in mesothelium and D/P Creatinine with PiT1 (with D/D0 Glucose p = 0.19, r = -0.41). Representative immunostaining of parietal peritoneum and of arterioles are given.
