Abstract

Ig-100, developed by the Swiss Red Cross, is a human immunoglobulin preparation for i. v. administration prepared by a modification of the Cohn ethanol fractionation process, incorporating mild acid treatment at pH 4. IG-100 has been evaluated clinically in Japan since 1982 in patients with severe bacterial and/or fungal infections which are resistant to antibiotic therapy.
Of 340 patients who received IG-100, 332 (97.6%) were adopted for safety evaluation and 183 (53.8%) were considered evaluable for efficacy. The adopted patients consisted of respiratory tract infections (42.2%), septicemia suspect (30.1%), septicemia (8.7%), urinary tract infections (3.0%) and others. The majority of patients had one or more underlying diseases, mainly including leukemia and/or other hematopoietic disorders (51.5%) and malignant tumor (19.9%).
Among 183 evaluable patients, clinical responses were excellent in 28, good in 74, fair in 28, poor in 43 and unknown in 10; efficacy rate being 59.0%. Causative organisms were isolated from 128 adopted patients. Among them 66 patients were evaluable for bacteriological effects which were eradicated in 36, partially eradicated in 4, decreased in 3, persisted in 18 and replaced in 5; eradication rate being 62.1%.
The analysis of the relation between clinical efficacy and leukocyte counts before and after IG-100 administration revealed that the highest efficacy rate was achieved in the patients whose leukocyte counts after IG-100 administration were in the normal range. The efficacy rate in the patients with lower leukocyte counts was much lower compared with that in the above mentioned patients. It is indicated that neutrophils and other leukocyte populations play an important role in the healing process of severe infections.
The rate of appearance of subjective and objective clinical side effects was 0.9% and none of the side effects observed was considered practically important. Abnormal laboratory findings because of IG-100 administration were not observed in 332 adopted patients.
In conclusion, combination therapy with IG-100 and antibiotics was considered to be safe and effective against severe bacterial and/or fungal infections.
