What this Trial Is About

The main objective of the study is to establish a database of clinical data and genetic data of patients diagnosed with ADPKD, with particular focus on those who have undertaken a specific therapy (Tolvaptan or Octreotide), afferent to the Integrated Renal Genetic Diseases Outpatient Clinic of the U.O. Nephrology, Dialysis and Transplantation of the Sant'Orsola-Malpighi Polyclinic directed by Prof. La Manna. In-depth analysis and comparison on clinical, laboratory and instrumental outcomes will be performed within this population. A thorough personal and family history will be obtained, and once informed consent is obtained, data will be entered and updated during subsequent outpatient monitoring. Attention is paid to the clinical course of the disease in relation to genetic variants (genotype-phenotype correlation) and treatments performed by patients, in order to monitor the progression of the disease to end-stage renal failure (ESRD) and the impact that specific therapy has on various parameters identified as indicating such progression. In particular, monitoring of the reduction in renal function, as assessed by creatinine, eGFR, 24-hour proteinuria, and urinary osmolarity values, with attention to comparing developmental trends toward ESDR between patients not receiving therapy and patients on specific therapy, and monitoring of the numerical and/or volumetric increase in renal cysts, as assessed by imaging comparison of the TKV value at the time of diagnosis of polycystic kidney disease and at subsequent re-evaluation, with attention to the extent of progression following the initiation of specific therapy, will be performed.
