RESUMO
First- and second-line treatments for immune checkpoint inhibitor-related hepatotoxicity (IRH) are well established; however, evidence for third-line therapies is limited. We present a 68-year-old female with relapsed metastatic non-small-cell lung carcinoma despite multiple treatments. A fortnight after the second cycle of CTLA-4 inhibitor immunotherapy, she developed scleral icterus and mild jaundice with significant elevation in liver enzymes. A diagnosis of IRH was made, and despite corticosteroids, mycophenolate and tacrolimus, liver enzymes continued to worsen. One infusion of tocilizumab was given, which resulted in a remarkable improvement. Prednisolone and tacrolimus were then tapered over the ensuing months, and mycophenolate was continued. Given the rapid improvement in liver enzymes with tocilizumab, this treatment should be considered as a third-line treatment in IRH.
A lady had cancer of the lung. A new medication was started but the liver became damaged. Three medications were tried to help the liver. None of these worked. Another drug (called tocilizumab) was tried and worked. The liver got better.
