Methylprednisolone and troleandomycin in treatment of steroid-dependent asthmatic children
Insights
This study shows that combining oral methylprednisolone and troleandomycin effectively treats severe pediatric asthma. The treatment improved lung function and reduced asthma exacerbations in children within weeks.
Area of Science:
- Pediatric Pulmonology
- Pharmacology
Background:
- Severe asthma in children poses significant management challenges.
- Steroid-dependent asthma requires careful therapeutic strategies to balance efficacy and side effects.
Purpose of the Study:
- To evaluate the efficacy and safety of oral methylprednisolone combined with troleandomycin in children with poorly controlled, severe asthma.
- To assess the impact of this combination therapy on clinical symptoms, pulmonary function, and healthcare utilization.
Main Methods:
- A cohort of 11 steroid-dependent children (aged 7-13 years) with poorly controlled asthma received the drug combination for 12-28 months.
- Clinical outcomes, pulmonary function tests (including forced expiratory volume in 1 second and maximal midexpiratory flow rate), and adverse events were monitored.
Main Results:
- Significant improvements in clinical symptoms and pulmonary function were observed within seven days.
- Forced expiratory volume in 1 second increased by 38% and maximal midexpiratory flow rate by 55% from baseline within the first week.
- By one year, forced expiratory volume in 1 second reached 98% of predicted value and maximal midexpiratory flow rate reached 79% of predicted value.
- Patients experienced fewer emergency visits, school absences, and hospitalizations compared to the previous year.
- Transient side effects included cushingoid features, abdominal pain, and elevated liver enzymes, with less evidence of adrenal suppression.
Conclusions:
- Oral methylprednisolone and troleandomycin combination therapy is effective for managing severe, poorly controlled asthma in children.
- This treatment regimen leads to rapid and sustained improvements in lung function and a reduction in asthma-related morbidity.
- The observed side effect profile appears manageable, with potential for reduced adrenal suppression compared to standard corticosteroid therapy.
Abstract:
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.
