Cytokine Removal under Hemodiafiltration with Endogenous Reinfusion in Acute Kidney Injury Secondary to Angioimmunoblastic T-Cell Lymphoma: A Case Report

Angioimmunoblastic T-cell lymphoma shows a high release of cytokines. Different blood purification techniques are employed to control hypercytokinemia. Here we investigated the effects of intermittent supra-hemodiafiltration with endogenous reinfusion on cytokine removal in a patient presenting with acute kidney injury. After the first day of chemotherapy for angioimmunoblastic T-cell lymphoma, a 78-year-old male patient developed acute kidney injury and systemic inflammatory response syndrome due to massive release of inflammatory cytokines. Three sessions of supra-hemodiafiltration were performed. Blood samples for evaluation of renal function and inflammatory mediators were collected at the beginning and the end of each dialytic session. A marked improvement of clinical state and renal function was associated to a significant reduction of inflammatory markers. Our results suggest that renal replacement therapy with supra-hemodiafiltration may remove a wide spectrum of inflammatory mediators and uremic toxins involved in acute kidney injury and systemic inflammatory response syndrome.
