| Summary: | A 59-year-old man with relapsed pulmonary TB developed rifampin resistance. He presented with chronic untreated hepatitis B, which developed into liver cirrhosis, type 2 diabetes with diabetic retinopathy, and osteoarthritis of right knee. His initial MDR regimen included levofloxacin, cycloserine, bedaquiline, linezolid, and high-dose isoniazid. He developed episodes of linezolid-induced myelosuppression, resulting in temporary discontinuation and dose reduction, and ultimately, substitution of linezolid. On the seventh month of treatment, he developed severe depression with visual hallucination, resulting in cycloserine dose reduction. We maintained the principle of at least 4 active drugs throughout his treatment. He was considered cured after 26 months of treatment.
