Objective: We aimed to evaluate the relationship between serum perilipin-2 / adipophilin (PLIN-2 / ADRP) levels and clinical course in patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD). Methods: 80 ADPKD patients with Chronic Kidney Disease (CKD) G1-G4 status, among the patients who were regularly followed up in the nephrology outpatient clinic between 2012 and 2019, were included in the study. CKD-G5 patients were excluded from the study. Baseline PLIN-2/ADRP levels were measured. Patients were divided into 2 groups according to the median serum PLIN-2/ADRP level. During the follow-up period, data such as blood pressure, height-adjusted total kidney volume (HtTKV), proteinuria, complete blood count, and biochemical tests were recorded. Results: In the patients with serum PLIN-2 / ADRP level above the median value (11.675 ng / mL), BMI was significantly higher than the other group (p<0.001). The female sex ratio was found to be significantly increased in patients with serum PLIN-2 /ADRP levels above the median value. Serum PLIN-2/ADRP levels were found to increase as eGFR decreased in ADPKD patients, but it was not statistically significant. In patients with high baseline mean PLIN-2/ADRP levels, the mean eGFR decline was found to be 20 ml/min/1.73 m2. However, the mean eGFR decrease in the other group with a low baseline PLIN-2/ADRP value was found to be 16 ml/min/1.73 m2 after 7 years of follow-up. Conclusion: PLIN-2 / ADRP levels increased in female ADPKD patients, and it is positively associated with BMI increase. Increased serum PLIN-2 / ADRP levels may be a harbinger of faster kidney function decline.
