Evaluation of Urinary Protein to Creatinine Ratio as a Predictor of End-State Renal Disease

ABSTRACT Objective:  To evaluate the role of urinary protein to creatinine (P:C) ratio as a predictor of end-stage renal disease (ESRD) in renal failure patients. Material and Method: This study was conducted at Liaquat National Medical College & Hospital, Karachi from Jan-Dec 2006 on 121 patients (77 males, 44 females) with acute renal failure (ARF) & chronic renal failure (CRF). Clinical history, relevant investigations, renal status, dialysis routine and frequency were recorded.  Random Urine samples (single void) were collected and the P:C ratio were calculated. Result: Out of 121 patients, 21 patients developed ESRD including 16 males (12 CRF, 4 ARF) and 5 females (all CRF). Statistical analyses shows no significant difference between sum of P:C ratio of CRF and ARF patients. However moderate significance (P ES ), depicts moderate (P category was 4.12 ± 0.82 (range 2.5 - 9.1) where as in male ARF end stage 3.78 ± 1.67 (range 1.80- 7.12). Mean P:C ratio in female CRF end stage category was 3.94 ± 0.79 (range 1.76 - 5.98). Conclusion: Patients with > 1.0 of P:C ratio has developed ESRD.  Higher the ratio of P:C, the more was risk of deterioration of clinical condition.
