BACKGROUND: Combination antibiotic regimens are effective in the treatment of actinomycetoma but many treatment schedules require supervised parenteral therapy for prolonged periods. We describe a schedule that includes parenteral medication in an initial, short phase followed by a longer phase of oral medication. METHODS: Sixteen patients with clinically diagnosed mycetoma, who did not show any evidence of a fungal etiology, were treated presumptively for actinomycetoma. Evidence of actinomycotic infection was found on microscopy of granules / discharge and / or histopathological examination in eight (50%) patients. The treatment consisted of an intensive phase (Step 1) with gentamicin, 80 mg twice daily, intravenously and cotrimoxazole, 320/1600 mg twice daily orally for four weeks. This was followed by a maintenance phase with cotrimoxazole and doxycycline, 100 mg twice daily till all sinuses healed completely. The treatment was continued for 5-6 months. RESULTS: Treatment response was assessed monthly. At the end of the intensive phase, there was a significant improvement in all 16 patients. Nine patients who continued the maintenance phase of the regimen had complete healing of sinuses with marked reductions in swelling and induration in 2.4 +/- 1.7 months. Maintenance treatment was continued for a mean of 9.1 +/- 4.3 months in these patients. Six patients have remained free of disease activity during a follow-up period of 11.1 +/- 4.2 months after treatment was stopped. Two patients developed leucopenia and thrombocytopenia necessitating withdrawal of cotrimoxazole. CONCLUSION: This regimen was effective in treating actinomycetoma. The short duration of the phase requiring parenteral therapy makes it convenient to administer.
