The objective of this prospective, randomized, double-blind, placebo-controlled clinical trial was to evaluate the efficacy of adjunctive therapy with iv human immunoglobulin G in reducing the morbidity and mortality associated with acute renal failure. Forty patients greater than or equal to 18 yr of age who were identified within 48 h of the onset of acute renal failure and who met the enrollment criteria were enrolled in the study. Thirty-five patients were considered evaluable. Patients were grouped according to the admitting service (medical or surgical/trauma) and were randomized to receive either immunoglobulin G (400 mg/kg body wt) or placebo (normal saline; 8 mL/kg body wt) at study entry and then weekly thereafter for a maximum of 4 doses. The groups were well balanced with respect to demographics, clinical presentation, and severity of illness (APACHE II scores). A significant reduction in mortality at 42 days after study entry was observed. Two of 17 (12%) patients in the immunoglobulin G-treated group compared with 8 of 18 (44%) patients in the placebo-treated group died (P = 0.025). No differences were observed in the frequency of major complications that occurred in association with acute renal failure. However, in patients who manifested infection, greater survival was observed in the immunoglobulin G treatment group. The results suggest that immunoglobulin G administered at the onset of acute renal failure reduced mortality possibly by decreasing the severity of infectious complications associated with the occurrence of of acute renal failure.(ABSTRACT TRUNCATED AT 250 WORDS).
