Objective: To analyze the pharmaceutical care process of anti-tuberculosis treatment for the patient with drug-induced liver injury (DILI) caused by immune checkpoint inhibitors, and provide reference for clinical anti-tuberculosis treatment of patients with DILI. Methods: One patient with lower esophageal squamous cell carcinoma after surgery showed abnormally elevated levels of alanine aminotransferase (385.47 U/L), alkaline phosphatase (456.59 U/L) and total bilirubin (156.17 μmol/L) during the second course of chemotherapy, with the manifestation of mixed type severe liver injury; during the period, the patient developed symptoms such as cough, expectoration, and fever (39°C), and acid-fast bacilli (+++) were detected in the sputum smear. Combined with the chest CT examination results, the patient was considered to have secondary pulmonary tuberculosis in both lungs. It was recommended to initiate anti-tuberculosis treatment with drugs. Results: After the patient developed liver injury, the clinical pharmacist considered that it was caused by chemotherapy drugs (the RUCAM scores of pembrolizumab, paclitaxel and carboplatin were 6, 5, and 4 respectively), but the drugs were not discontinued. The patient received hepatoprotective treatment with adenoglycine butanesulfonate, polyene phosphatidylcholine, and methylprednisolone on the basis of magnesium isoglycyrrhizinate, however, the liver injury indicators continued to worsen, so all drugs with potential risks of liver injury were discontinued; subsequently, when carrying out anti-tuberculosis treatment, taking into account the patient's current liver injury, the doctor adopted the clinical pharmacist's suggestion and used drugs with a low risk of liver injury such as ethambutol, levofloxacin, and streptomycin; during this period, the patient's liver injury indicators kept improving; and then isoniazid was added and streptomycin was changed to linezolid; one month later, the patient's liver function returned to normal. Conclusion: When patients with severe mixed DILI need to carry out anti-tuberculosis treatment, clinical pharmacists should assist doctors in successfully treating patients with DILI and carrying out anti-tuberculosis treatment based on their professional knowledge and relevant literature reports, to ensure the life health of patients.
