Anti-lipopolysaccharide-immunoglobulin (IgG-anti-LPS) therapy in intensive care patients following surgery from infectious disease.

In 18 intensive care patients the effect of a IgG-Anti-Lipopolysaccharide (Anti-LPS), was investigated in a randomized study following surgery after bacterial infections, mostly peritonitis. Fresh frozen plasma was administered during the first 5 postoperative days, containing either more than 65 micrograms/ml Anti-LPS in the therapy group or less than 12.5 micrograms/ml in the control group. The serum level of Anti-LPS was monitored. Clinical and chemical parameters were recorded to evaluate infectious complications and outcome of the patients. The mortality in the treatment group was not different from the control group with 30% (3 out of 10) and 25% (2 out of 8), respectively. No beneficial effect was observed either from the administration of Anti-LPS or from endogenously produced Anti-LPS on any clinical parameter in our patients.
