Summary
This study quantifies renal failure progression in 277 patients, finding that controlling blood pressure and serum phosphate slows kidney disease. Higher initial creatinine and more frequent visits correlated with slower progression, impacting long-term renal survival.
Area of Science:
- Nephrology
- Internal Medicine
- Clinical Research
Background:
- Renal failure progression is a significant concern in chronic kidney disease (CKD).
- Effective management strategies aim to slow the decline in kidney function.
- Controlling hypertension and hyperphosphatemia are key therapeutic goals.
Purpose of the Study:
- To determine the rate of renal failure progression in a cohort of CKD patients.
- To identify factors influencing the rate of kidney function decline.
- To estimate renal survival time to dialysis.
Main Methods:
- Calculated rates of progression using the slope of reciprocal creatinine versus time.
- Analyzed data from 277 patients with at least five clinic visits.
- Correlated progression rates with baseline creatinine and clinic visit frequency.
Main Results:
- The mean rate of progression was -0.0054 dL/mg/mo, with a median of -0.00315 dL/mg/mo.
- Progression rate was inversely correlated with baseline creatinine concentration (P < 0.004) and visit frequency (P < 0.01).
- Mean renal survival time from 10 mg/dL creatinine to dialysis was 10.0 months.
Conclusions:
- Vigorous control of blood pressure and serum phosphate can slow renal failure progression.
- Higher baseline creatinine and increased clinic visit frequency are associated with slower progression.
- These findings offer valuable insights into CKD progression rates and influencing factors.
