Maintenance therapy with cotrimoxazole for toxoplasmic encephalitis in the era of highly active antiretroviral therapy.

To reduce the number of daily pills for improving adherence to antiretrovirals, 17 protease inhibitor-treated patients receiving toxoplasmic encephalitis (TE) standard maintenance therapy were instead given cotrimoxazole 960 mg twice daily. After a median follow-up of 31 months, one relapsed after three months, TE relapse incidence = 2.1 cases per 100 patient-years (95% confidence interval, 0.05-11.3). This strategy could be useful for patients awaiting immune reconstitution which allows the interruption of TE maintenance therapy.
