[Clinical and laboratorial predictors related to progression to chronic kidney disease in patients with autosomal dominant polycystic kidney disease].

Objective: To determine clinical and laboratorial factors related to progression to chronic kidney disease in patients with autosomal dominant polycystic kidney disease (ADPKD).
Material and Methods: Retrolective cohort. We reviewed the files of patients with diagnosis of ADPKD between 1980 and 2008. We collected demographic, clinical and laboratory data. The primary endpoint was the development of advanced kidney disease (GFR estimated < 15 mL/min with MDRD, renal replacement therapy or kidney transplantation). The Cox proportional hazards model was used to investigate the effect of clinical and laboratorial covariates on the progression to advanced kidney disease.
Results: Advanced chronic kidney disease developed in 37.4% (n = 34) of the patients with median survival renal of 57 years (IC95% 50.3-63.8). Variables associated with progression to advanced chronic kidney disease in the multivariate analysis were the levels of serum creatinine (HR = 1.59 IC95% 0.99-2.55 p = 0.05) and dyslipidemia (HR = 3.40; IC95% 1.23-9.39; p = 0.01).
Conclusions: Progression to advanced chronic renal failure was common in our population and the predicting factors for progression were the levels of serum creatinine and dyslipidemia.
