The incidence of corticosteroid side effects in chronic steroid-dependent asthmatics on TAO (troleandomycin) and methylprednisolone.
The purpose of this study was to determine the effect of troleandomycin (TAO)-methylprednisolone (MP) regimens on the incidence of corticosteroid-induced side effects. Retrospective analysis was performed on the charts of 29 adult chronic steroid-dependent asthmatics on regimens of TAO-MP. These 29 met our criteria of a minimum of 1 year on TAO-MP and at least 6 to 12 months on daily or alternate-day corticosteroids before TAO-MP was instituted. Charts were reviewed for nine known corticosteroid (CS) side effects, all previously identified side effects were excluded. Charts were also reviewed for TAO dose, MP dose, and dose/duration on CS therapy before TAO-MP regimen began. Patients on TAO at an average dose of 250 mg/d were able to wean to an average MP dose of 10.8 mg every other day from an average MP equivalent dose of 16.8 mg every other day before TAO. In spite of lower MP doses on TAO we found that 35% showed an increase in CS-induced side effects, some (three) had more than one side effect. Three patients developed cataracts (10%), two become hypertensive (6.8%), one developed diabetes (3%), one had a psychotic episode (3%), and one patient developed TB (3%) and had a spinal compression fracture. Sixty percent of these patients were on 8 mg or less of MP on an alternate-day basis. We found that in this group of 29 chronic steroid-dependent asthmatics the incidence of corticosteroid-related side effects was increased on TAO-MP regimens despite a reduction in corticosteroid dose.
