title: Association of kidney and cysts dimensions with anthropometric and biochemical parameters in patients with ADPKD.
abstract: The aim of the study was to evaluate an association between kidney and cyst dimensions and anthropometric, clinical and biochemical parameters of autosomal dominant polycystic kidney disease (ADPKD) patients. Forty-nine adults, ADPKD-diagnosed patients aged 36 ± 11 years, and 50 healthy controls were included in the study. Oral glucose tolerance test (OGTT with 75 g of glucose) was performed and venous blood was collected to measure biochemical parameters and various ion concentrations. Ultrasound abdominal examinations were performed with special emphasis on kidney and cysts parameters. In the ADPKD group, mean kidney length correlated positively with age, systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glucose and glucose and C-peptide concentrations after 120 min of glucose intake and negatively with Mg(2+) concentration and glomerular filtration rate (eGFR). Multivariate analyses adjusted for age and gender showed that higher mean kidney length and maximal cyst diameter were significant predictors of higher SBP (p = 0.034 and 0.046, respectively) and DBP (p = 0.024 and 0.034, respectively), higher maximal cyst diameter was a significant predictor of higher OGTT 2-h C-peptide concentration (p = 0.033), higher mean cyst diameter was a significant predictor of lower eGFR (p = 0.039) and higher mean kidney length was a significant predictor of lower serum magnesium concentration (p = 0.043). In the ADPKD patients with normal GFR, mean kidney length and mean cyst diameter measured by ultrasonography are associated negatively with GFR and positively with blood pressure. Higher mean kidney length and cyst diameter might be indicators of disorders of glucose and magnesium metabolism which precede renal failure in patients with ADPKD.
