Amoxicillin and clavulanic acid in the treatment of actinomycetoma.
BACKGROUND
Mycetoma is a relatively frequent disease in tropical countries. Drugs commonly used need a long period of treatment, and some cases are resistant to these drugs, especially those with bone or visceral involvement. The combination of amoxicillin-clavulanic acid has shown effectiveness against strains of Nocardia brasiliensis in vitro.


METHODS
We have used this combination in two cases of mycetoma caused by N. brasiliensis, both with bone involvement and resistance to the drugs usually used. A dose of three tablets a day for 5 to 6 months was given (each tablet contains 500 mg of amoxicillin and 125 mg of clavulanic acid).


RESULTS
Clinical and mycologic amelioration was observed in the two cases after completing the treatment. There were no side effects or relapses after 3 to 6 months of follow-up after treatment.


CONCLUSIONS
We propose this antibiotic as a new option for the treatment of some special cases of actinomycetoma with bone or visceral involvement or resistance to the drugs commonly used in this disease.
