Clinical studies on SM-4300, a new human gammaglobulin preparation for intravenous use in pediatrics

Six cases of severe infections in pediatrics, which showed no or insufficient responses to treatment with antibiotics, were treated with additional intravenous infusion of SM-4300. Results were as follows. Three cases of bacterial infections with high fever, showing no response to chemotherapy, were treated with SM-4300, (68-135 mg/kg). Administration of SM-4300 resulted in defervescence, decreasing pain and swelling and showing a trend for improvement in CRP values. Administrations of SM-4300 (61-100 mg/kg) against pleurisy caused by Mycoplasma were effective in defervescence and improvement in chest findings. Clinical effects of SM-4300 were excellent in 2 cases, good in 3 and fair in 1. In this study, no clinical side reactions nor abnormal laboratory values in blood, liver or renal functions were observed.
