Relationship between septic acute kidney injury and adiponectin: A retrospective study in patients undergoing continuous plasma exchange with dialysis.

Introduction: Adiponectin (APN) is a multimeric protein with anti-inflammatory properties that is specifically secreted by adipocytes. Continuous plasma exchange with dialysis (cPED) is a blood purification therapy in which plasma exchange is performed using a selective membrane plasma separator while the dialysate flows outside the hollow fibers.

Methods: Patients with sepsis were divided into two groups based on the presence or absence of acute kidney injury (AKI) complications: AKI and non-AKI group.

Results: Plasma APN levels significantly increased after cPED in both groups. The creatinine levels in the AKI group before cPED were significantly higher than those in the non- AKI group. The plasma APN levels in the AKI group before cPED were significantly higher than those in the non-AKI group.

Conclusion: cPED increased APN levels in both patients with and without AKI. Therefore, cPED therapy may be a promising intervention for increasing APN levels in patients with sepsis.
