Figure 3. Clinical course. The diagnosis of disseminated tuberculosis (TB) was established. Thereafter, 4 anti-TB drugs were administered immediately. Twenty days after the start of the administration, the serum alanine aminotransferase (ALT) levels decreased to normal. After 1 month, streptomycin (SM) was replaced with ethambutol because of concerns about an auditory disorder. After 2 months of the 4-drug antituberculotic therapy, pyrazinamide and ethambutol (EB) were discontinued, but treatment with isoniazid and rifampin was continued. Approximately 6 months after the initiation of therapy, the patient’s liver function test results showed improvement.
