[Relapsing polychondritis with predominant respiratory involvement treated with Dapsone :value of pulmonary function tests (author's transl)].

A 31-year-old patient had developed lesions in the nasal cartilage during infancy, followed by laryngotracheal lesions when 9 years old. The latter lesions recurred when he was 21, followed several years later by an affection of the main left bronchus and the diagnosis of relapsing polychondritis. Initial respiratory function tests showed mainly a reduction in maximum inspiratory flow, due to sequelae in the upper respiratory tract. Repeated tests were able to demonstrate lesions in the main left bronchus, determining severe expiratory slowing. No significant improvement occurred after one year of corticoïd therapy. Treatment with sulfones (Disulone) produced clinical improvement (reappearance of a vesicular murmur in the left lung) and a twofold increase in FEV1. Functional improvement was even better demonstrated by successive flow-volume curves.

Persister M. leprae after introductory rifampicin followed by dapsone therapy.

Lepromatous patients of "Introductory Rifampicin therapy' (Lepr. India, 50: 1978) who received 300 mg Rifampicin daily for 3 months followed by 50-100 mg DDS daily for another 21 months are investigated for persisters in the skin. Mouse foot pad results revealed that at the end of 2 years of treatment viable M. leprae are still persisting in 3 out of 6 patients.
