Risk factors for technique failure due to peritonitis by multivariate Cox proportional hazards regression analysis
| HR (95% CI) | p Value | |
|---|---|---|
| Residual renal function (mL/min/1.73 m2) | 0.883 (0.73 to 1.06) | 0.192 |
| Body mass index | 1.088 (1 to 1.19) | 0.059 |
| Uric acid | 1.298 (1.07 to 1.57) | 0.008* |
| Tunnel infection rate | 0.854 (0.01 to 54.41) | 0.941 |
| Peritonitis rate | 20.960 (8.33 to 52.76) | <0.001* |
| Icodextrin use | 0.078 (0.03 to 0.23) | <0.001* |
The analysed variables included gender, age, BMI, comorbid conditions, and the use of ACE inhibitor, ARB, β-blocker, CCB, hypouricaemic agents, diuretics, BUN, creatinine, haemoglobin, ferritin, HbA1c, serum albumin, Ca×P, GPT, residual renal function, icodextrin use, Balance dialysate use, assistance for dialysate exchanges, peritoneal Kt/V, weekly total Kt/V urea, nPNA, D/P (creatinine) at 4 hours, ultrafiltration, 24-hour urine output, and exit-site infection, tunnel infection, number of exchanges per day and peritonitis rate.
*p Value <0.05.
ARB, angiotensin II receptor blocker; BUN, blood urea nitrogen; CCB, calcium channel blocker; HbA1c, glycated haemoglobin.
