• Oral methylprednisolone combined with troleandomycin has been reported to be successful in treating poorly controlled, severe asthma in adults. We found this drug combination to be effective in treating 11 steroid-dependent children with poorly controlled asthma who were aged 7 to 13 years, for 12 to 28 months. Improvement of clinical and pulmonary functions was achieved within seven days, with the forced expiratory volume in 1 s increasing by 38% and the maximal midexpiratory flow rate increasing by 55% over the baseline value. By one year, the former improved to 98% of predicted value and the latter, to 79% of predicted value. Compared with the prior 12 months, patients at this time required fewer emergency visits, missed fewer days of school, and had fewer hospitalizations. Side effects included transient-increased cushingoid features, abdominal pain, and liver enzyme level elevation. Patients showed less evidence of adrenal suppression.
