Spiramycin was compared with erythromycin in a guinea pig model of severe Legionella pneumophila serogroup 1 infection. Male guinea pigs weighting 264-321 g were infected by the intraperitoneal route with 1.2 x 10(7) virulent L. pneumophila serogroup 1. Forty eight h after infection, animals that had lost greater than or equal to 9% of their body weight were randomly assigned to receive 48, 54 and 72 h after infection intraperitoneal injections of (1) distilled water (n = 20), (2) erythromycin lactobionate, 30 mg/kg per injection, (n = 22) or (3) the injectable form of spiramycin adipate, 30 mg/kg per injection (n = 22). Animals were observed daily for 15 days. All infected animals treated with distilled water died within four days of infection. Of the 22 animals treated with spiramycin, 10 (45.5%) died, and of the 22 animals treated with erythromycin, 11 (50.0%) died of disseminated L. pneumophila infection. In this animal model of very severe L. pneumophila infection, the injectable forms of erythromycin and of spiramycin gave similar results. Spiramycin should therefore be considered for the treatment of Legionnaires' disease in man.

This paper reports the results of an open study to assess the efficacy (433 patients) and tolerance (453 patients) of spiramycin adipate given by slow intravenous infusion to treat severe acute bronchopulmonary infections in adults. Efficacy was good in 80.4% of patients. More specifically, high efficacy was obtained in 76.5% of 85 pneumococcal respiratory infections, 72% of 50 Haemophilus influenzae and H. parainfluenzae infections, 100% of 18 Mycoplasma infections, 100% of 16 Chlamydia infections and 93% of 14 Legionella infections. Tolerance was good in 83.5% of patients, moderate in 15.4% and poor in 6%. Venous irritation was the most frequent complication, observed in 16.3% of patients. No serious complication or sequel was observed. The authors conclude that spiramycin adipate constitutes an appropriate first-line treatment of acute bronchial and/or pulmonary infections in adults. While inferior to benzylpenicillin against Mycoplasma, Chlamydia and Legionella, spiramycin is as active as, and better tolerated than, erythromycin.
