The protective effect of high-titer anti-lipid A hyperimmune globulin with respect to the course of the disease and the mortality rate was studied in patients with septicemia verified by positive blood cultures. Six patients were treated with anti-lipid A in an open study. Dramatic improvement in fever curves and clinical condition in some of the patients encouraged us to start a randomized double blind study. So far, 17 patients have entered the study, 16 of whom were evaluable. Immediately after a positive blood culture was found, patients received either high doses of anti-lipid A or placebo (saline solution) on two subsequent days. Before and after each infusion blood samples were taken in order to assess serum bactericidal activity and anti-lipid A titers. Because of the still small numbers of patients the results of both studies were summarized. In all patients treated with anti-lipid A clear-cut increases in anti-lipid A titers were shown. Patients with repeated gram-negative infections showed higher median anti-lipid A titers than patients without such a history. The patients treated with anti-lipid A immune globulin ran a significantly milder course than the placebo group. The severe signs of septic shock were reversed in seven of 15 patients on anti-lipid A compared to two of seven patients treated with placebo. In the anti-lipid A-treated group, three of 15 patients died, and in the placebo group two of seven. This difference is not statistically significant.
