- Abstract
Autosomal dominant polycystic kidney disease (ADPKD) is one of the main causes of end-stage renal disease. Today, the knowledge of its genetic base has made it possible to develop strategies that prevent the transmission of the disease. Objectives: The objective of the study was to analyze the natural history of ADPKD in the Province of Córdoba and to design a database that allows families and different mutations to be grouped. Patients and methods: All patients (n = 678) diagnosed with ADPKD followed up in the Cordoba nephrology service are included. Various clinical variables (age and sex), genetic variables (mutation in PKD1, PKD2) and the need for renal replacement therapy (RRT) were retrospectively analyzed. Results: The prevalence was 61 cases per 100,000 inhabitants. Median renal survival was significantly worse in PKD1 (57.5 years) than in PKD2 (70 years) (Log-rank p = 0.000). We have genetically identified 43.8% of the population, detecting mutations in PKD1 in 61.2% and in PKD2 in 37.4% of cases. The most frequent mutation was detected in PKD2 (c.2159del) in 68 patients belonging to 10 different families. The one with the worst renal prognosis was detected in PKD1 (c.9893G>A). These patients required RRT at a median age of 38.7 years. Conclusions: The renal survival of ADPKD in the Province of Córdoba is similar to that described in the literature. Mutations in PKD2 were detected in 37.4%. Our strategy allows us to know the genetic bases of our population with a great saving of resources. This is essential to be able to offer primary prevention of ADPKD through preimplantation genetic diagnosis.
