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 300mg/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.

We report here a case of relapsing polychondritis (RPC), who responded to salazosulfapyridine (SASP) after 1.5 years of active disease. A 15-year-old girl having chondritis of bilateral auricles, nose and respiratory tract, ocular inflammation, cochlear and vestibular dysfunction and seronegative polyarthritis was diagnosed as RPC, and oral corticosteroid was initially effective. She was admitted to our hospital with obstructive tract chondritis and was refractory to any of the treatment such as intravenous (IV) pulse steroid therapy, IV pulse cyclophosphamide (CPA), oral intermittent methotrexate (MTX) and high dose IV γ globulin. Although she was partly responsive to oral cyclosporine A (CsA), but clinical symptoms did not completely subside. SASP, initiated in combination with oral corticostreroid and CsA, however, was successful not only to show steroid sparing effect but also to induce complete remission.
SASP might be useful to refractory case of RPC.

A 56-year-old man experienced dyspnea since August 1995 and the chest X-ray film showed abnormal shadow. The diagnosis of bronchiolitis obliterans organizing pneumonia (BOOP) was established based on the histological findings of transbronchial lung biopsy. The patient was treated with prednisolone and symptoms improved. Myalgia and muscle weakness developed associated with relapse of BOOP after withdrawal of prednisolone. Patient was adimitted to our department on December 1995 for further examination. An increased level of serum CPK, histological findings of muscle biopsy consistent with myositis, and positive anti-Jo-1 antibody were identified. Those findings supported a diagnosis of polymyositis (PM), and BOOP was considered as a pulmonary complication of PM. Myositis and pulmonary lesion improved after second course of steroid therapy and patient was discharged on May 1996. Both chronic pulmonary fibrosis and acute progressive interstitial pneumonia are well known as pulmonary lesion associated with PM. The former is frequently recognized in cases of PM with anti-Jo-1 antibody and the latter is often observed in cases without autoantibodies. The association of PM and BOOP, however, has rarely been reported. The findings that BOOP frequently preceded PM and anti-Jo-1 antibody was positive in half of the cases were observed in the literature.
