A random controlled study of the prophylactic effect of lysozyme chloride on post-transfusion hepatitis

In a study designed to determine the preventive effect of lysozyme on post-transfusion hepatitis, 260 patients with orthopedic diseases, who received blood by transfusion during a period of 5 years from June 1970 to May 1975, were divided at random into a group of 123 patients treated with lysozyme is doses of 60 to 170 mg/day for 4 to 24 weeks, and a control group of 137 patients. The incidence of post-transfusion hepatitis was 10 (8.1%) out of 123 patients for the treated group, and 28 (20.4%) out of 137 patients for the control group. Icteric hepatitis occurred in 1 (0.8%) patient in the treated group, while its incidence in the control group was 8 (5.8%) out of 137 patients.
