A series of five cases with Wegener's granulomatosis (WG) is presented: two women and three men with an average age of 37 years old, with an average time of evolution of the disease of 5 years and systemic clinical presentation (respiratory, renal and ocular affection); the ANCA were positive; three of them were carriers of Staphylococcus aureus. All the patients received combined therapy composed by trimethoprim-sulfamethoxazole-cyclophosphamide (TMS-CFM) during approximately 29 months of follow- up, except for a pregnant patient. The patients showed a satisfactory clinical evolution with improvement of the manifestations of the disease. We suggest that, due to its benefits, the combination of TMS-CFM can be useful as a therapeutic alternative in WG.
