Intravenous immunoglobulin (GB-0998) for prophylaxis of recurrent acute otitis media and lower respiratory tract infection in infancy with IgG 2 deficiency

Abstract

The prophylactic effect of intravenous immunoglobulin (GB-0998) on the recurrent acute otitis media, bronchitis and bronchopneumonia in IgG 2 deficient infants was investigated in a multicenter trial. GB-0998 was administered 6 times every 4 weeks. The doses were 300 mg/kg wt. during the first treatment, followed by 5 doses of 200 mg/kg wt. The results indicated that GB-0998 was effective in the prophylaxis of the recurrent infection of acute otitis media, bronchitis and bronchopneumonia in infancy with IgG 2 deficiency and/or IgG 2 antibody deficiency specific for Streptococcus pneumoniae. © 1998, The Japan Society for Clinical Immunology.
