Clinical characterization of acute renal failure in multiple organ dysfunction syndrome

Acute renal failure frequently occurs as a complication of multiple organ dysfunction syndrome (MODS). Various forms of therapy for MODS, including endotoxin absorption and anticytokine therapy, have been attempted.
We retrospectively studied the pathophysiologic characteristics of acute renal failure in 152 MODS patients examined in our department over the past 5 years. The diagnosis of MODS was based on the criteria of the Japanese Association for Critical Care Medicine. The diagnosis of systemic inflammatory response syndrome (SIRS) and sepsis was conducted in accordance with the definition proposed at the 1992 Consensus Conference of the American College of Chest Physicians/ Society of Critical Care Medicine.
Acute renal failure occurred as a complication of secondary MODS with a high frequency of 76.3% (116/152 patients). Significant associations have been found between the respective frequencies of acute renal failure and disseminated intravascular coagulation occurring as complications of SIRS. An increase in the number of cases undergoing continuous hemodiafiltration was noted, in an attempt to improve the survival rate of MODS complicated with acute renal failure.
Acute renal failure seen in secondary MODS is thought to be derived from a pathogenesis differing from that of conventional intrinsic acute renal failure, such as ischemic and nephrotoxic forms. Acute renal failure associated with secondary MODS appears to be a disease entity that arises as a sequela of SIRS, similar to disseminated intravascular coagulation.
