Final susceptibility results demonstrated resistance to isoniazid, rifampicin, rifabutin, clofazimine, and streptomycin with sensitivity to ethambutol, pyrazinamide, amikacin, capreomycin, ciprofloxacin, cycloserine, and ethionamide. The regimen was continued without rifabutin.
Patient was a known case of multidrug resistant tuberculosis and was being treated with the following drugs for two months: amoxicillin-clavulanate, ethionamide, intramuscular capreomycin, linezolid, and para-aminosalicylate (PAS) granules.
Considering the patient previous treatment schemes, and based on expert's opinion, after normalization of liver enzymes, a slower reintroduction of second-line drugs was made: starting with levofloxacin 750 mg/day and amikacin 750 mg/day, twenty days later adding ethionamide 500 mg/ day and 27 days later adding cycloserine 500 mg/day.
The second-line drugs are kanamycin, ciprofloxacin, ethionamide, and so on.
