Immune checkpoint inhibitors target pathways involved in immune regulation, including cytotoxic T lymphocyte associated protein 4 (CTLA-4) and programmed cell death protein 1 (PD-1). Their therapeutic use is well-established for many solid-organ, haemotological and skin malignancies, such as metastatic melanoma, in which a notable survival benefit has been reported with combination anti-CTLA-4 (Ipilimumab) and anti-PD-1 (Nivolumab) agents.1Wolchok JD Chiarion-Sileni V Gonzalez R Rutkowski P Grob J-J Cowey CL et al.Overall Survival with Combined Nivolumab and Ipilimumab in Advanced Melanoma.N Engl J Med. 2017; 377: 1345-1356Crossref PubMed Scopus (2215) Google Scholar, 2Larkin J Chiarion-Sileni V Gonzalez R Grob JJ Cowey CL Lao CD et al.Combined Nivolumab and Ipilimumab or Monotherapy in Untreated Melanoma.N Engl J Med. 2015; 373: 23-34Crossref PubMed Scopus (5116) Google Scholar However, immune-related adverse events (IrAEs) are common and when used in combination can affect greater than 95% of patients. The incidence of severe or life-threatening events (Common Terminology Criteria for Adverse Events (CTCAE) grade 3-4) is 55%, and immune-related hepatitis is reported in up to 18% of those on combination therapy, vs. 1–4% and 4–9% with anti-PD1 and anti-CTLA-4 monotherapy, respectively. However, the extent of liver injury is variable and most cases are not severe.[3]De Martin E Michot JM Papouin B Champiat S Mateus C Lambotte O et al.Characterization of liver injury induced by cancer immunotherapy using immune checkpoint inhibitors.J Hepatol. 2018; 68: 1181-1190Abstract Full Text Full Text PDF PubMed Scopus (266) Google Scholar Oncology guidelines for managing IrAEs are based on algorithms developed for trials of checkpoint inhibitors and extensive experience, but have not themselves been validated.4Brahmer JR Lacchetti C Schneider BJ Atkins MB Brassil KJ et al.Management of immune-related adverse events in patients treated with immune checkpoint inhibitor therapy: American Society of Clinical Oncology Clinical Practice Guideline.J Clin Oncol. 2018; 2018 (JCO2017z776385)https://doi.org/10.1200/JCO.2017.77.6385Crossref Scopus (1966) Google Scholar, 5Haanen J Carbonnel F Robert C Kerr KM Peters S Larkin J et al.Management of toxicities from immunotherapy: ESMO Clinical Practice Guidelines for diagnosis, treatment and follow-up.Ann Oncol. 2017; 28: iv119-iv142Abstract Full Text Full Text PDF PubMed Scopus (1305) Google Scholar Management is tailored to the CTCAE grade; for those with grade 1 hepatitis (alanine aminotransferase [ALT] ≤3 x upper limit of normal [ULN]) immune therapy might continue with monitoring, whereas for those with grade 3 hepatitis (ALT ≥5xULN and a raised bilirubin) treatment is stopped and methylprednisolone 1–2 mg/kg/day or equivalent is initiated. In all cases, alternative causes for hepatotoxicity should be excluded. Current guidelines state that liver biopsy is not required to make the diagnosis, but should be reserved for patients refractory to treatment.4Brahmer JR Lacchetti C Schneider BJ Atkins MB Brassil KJ et al.Management of immune-related adverse events in patients treated with immune checkpoint inhibitor therapy: American Society of Clinical Oncology Clinical Practice Guideline.J Clin Oncol. 2018; 2018 (JCO2017z776385)https://doi.org/10.1200/JCO.2017.77.6385Crossref Scopus (1966) Google Scholar, 5Haanen J Carbonnel F Robert C Kerr KM Peters S Larkin J et al.Management of toxicities from immunotherapy: ESMO Clinical Practice Guidelines for diagnosis, treatment and follow-up.Ann Oncol. 2017; 28: iv119-iv142Abstract Full Text Full Text PDF PubMed Scopus (1305) Google Scholar De Martin and colleagues, in contrast, have recently highlighted the potential benefits of pre-treatment histology to clarify disease pattern and severity, in order to minimise exposure to immunosuppression in self-limiting cases.[3]De Martin E Michot JM Papouin B Champiat S Mateus C Lambotte O et al.Characterization of liver injury induced by cancer immunotherapy using immune checkpoint inhibitors.J Hepatol. 2018; 68: 1181-1190Abstract Full Text Full Text PDF PubMed Scopus (266) Google Scholar Whilst the majority of cases resolve within 4–6 weeks of treatment, there is a paucity of data about optimal management of steroid-refractory liver IrAEs. The anti-TNF agent, infliximab, is widely used as salvage for IrAE colitis but never for hepatitis. Herein, we report the first case of its successful use as a rescue therapy in life-threatening, refractory immune-mediated hepatitis, in a patient on combination anti-CTLA-4 (Ipilimumab) and anti-PD-1 (Nivolumab) therapy for metastatic melanoma. A 53-year-old lady had a left abdominal cutaneous melanoma (Breslow >3.7 mm) resected in 2016, followed by extra-capsular spread on axillary node block dissection in 2017. Widespread hypermetabolic new malignancy was demonstrated on computer tomography (CT)/positron emission tomography (PET) scan in the left breast/axilla/shoulder/subpleural space, right adrenal, small bowel, and bone as well as extensive hepatic metastatic disease. The melanoma carried the V600 BRAF mutation and <1% of metastatic cells expressed programmed death ligand 1 (PDL1). She was treated from the start with combination ipilimumab 3 mg/kg and nivolumab 1 mg/kg 3-weekly, completing her third cycle in November 2017. Of note, her liver function tests (LFTs) were normal prior to the third cycle of therapy. She was admitted 18 days after the third cycle with lethargy, nausea, anorexia and dark urine. She was febrile (39oC) with a widespread morbiliform rash. Bilirubin was 93 μmol/L (normal <22 μmol/L), ALT 1,135 IU/L (normal ≤41 U/L), ALP 857 IU/L (normal females ≤105 U/L), albumin 35 g/L (normal 34–51 g/L) with normal clotting and C-reactive protein 27.8 mg/L (normal <10 mg/L). Initial white cell count and renal function were normal. She was a non-smoker, did not drink alcohol and had no other relevant medical/family history. Hepatitis A, B, C, E, cytomegalovirus (CMV) and human immunodeficiency virus were negative. Extended liver autoimmune antibodies were all negative and IgG concentrations were 8.26 g/L (normal range 6–16 g/L). CT showed multiple liver metastases, but no biliary dilatation. As per guidelines for immune-related hepatitis4Brahmer JR Lacchetti C Schneider BJ Atkins MB Brassil KJ et al.Management of immune-related adverse events in patients treated with immune checkpoint inhibitor therapy: American Society of Clinical Oncology Clinical Practice Guideline.J Clin Oncol. 2018; 2018 (JCO2017z776385)https://doi.org/10.1200/JCO.2017.77.6385Crossref Scopus (1966) Google Scholar, 5Haanen J Carbonnel F Robert C Kerr KM Peters S Larkin J et al.Management of toxicities from immunotherapy: ESMO Clinical Practice Guidelines for diagnosis, treatment and follow-up.Ann Oncol. 2017; 28: iv119-iv142Abstract Full Text Full Text PDF PubMed Scopus (1305) Google Scholar 200 mg of intravenous methylprednisolone once daily was given. Despite 5 days of such, ALT persisted above 1,000 IU/L and jaundice progressed (Fig. 1). Treatment was escalated with mycophenolate mofetil (MMF) 1g twice daily to no avail and a percutaneous liver biopsy was performed on day 10 of immunosuppressive treatment (Fig. 2A-B ). This showed severe acute lobular hepatitis in the absence of fibrosis and a predominance of CD3+CD8+ lymphocytes throughout. After 7 days of dual therapy she developed severe neutropenia (<0.1x109/L) and MMF was discontinued. On day 21 of high-dose corticosteroid therapy the bilirubin was 474 μmol/L and a second liver biopsy was undertaken, which showed severe lobular CD3+CD8+ T-cells predominant hepatitis with confluent/bridging necrosis and evolving mild peri-portal fibrosis, without malignant cells (Fig. 2C-D). Clinically, there were no features of liver failure (no encephalopathy/ascites, international normalized ratio 20xULN).1Wolchok JD Chiarion-Sileni V Gonzalez R Rutkowski P Grob J-J Cowey CL et al.Overall Survival with Combined Nivolumab and Ipilimumab in Advanced Melanoma.N Engl J Med. 2017; 377: 1345-1356Crossref PubMed Scopus (2215) Google Scholar, 2Larkin J Chiarion-Sileni V Gonzalez R Grob JJ Cowey CL Lao CD et al.Combined Nivolumab and Ipilimumab or Monotherapy in Untreated Melanoma.N Engl J Med. 2015; 373: 23-34Crossref PubMed Scopus (5116) Google Scholar A prospective pharmacovigilance registry identified 19/536 (3%) with grade 3 hepatitis with checkpoint inhibitors, including 4 that received combination therapy.[3]De Martin E Michot JM Papouin B Champiat S Mateus C Lambotte O et al.Characterization of liver injury induced by cancer immunotherapy using immune checkpoint inhibitors.J Hepatol. 2018; 68: 1181-1190Abstract Full Text Full Text PDF PubMed Scopus (266) Google Scholar Our case represents a very severe immune-related hepatitis occurring after the third cycle of ipilimumab and nivolumab. Sequential liver biopsies demonstrated an acute lobular, CD8+ T-cell predominant hepatitis, which was refractory to corticosteroids and MMF. Concerningly, the injury progressed to confluent/bridging necrosis and fibrosis, despite improvement in LFTs. Previously reported histological patterns of immune-related hepatitis are diverse; ranging from granulomatous hepatitis with fibrin deposition and central vein endothelitis in recipients of anti-CTLA-4+/- anti-PD-1 to more heterogeneous lobular and periportal injury in recipients of anti-PD-1 or PDL1 agents.[3]De Martin E Michot JM Papouin B Champiat S Mateus C Lambotte O et al.Characterization of liver injury induced by cancer immunotherapy using immune checkpoint inhibitors.J Hepatol. 2018; 68: 1181-1190Abstract Full Text Full Text PDF PubMed Scopus (266) Google Scholar Three patients with anti-PD-1 induced grade 4 transaminitis and jaundice had varying degrees of biliary duct damage and ductopenia on biopsy.[4]Brahmer JR Lacchetti C Schneider BJ Atkins MB Brassil KJ et al.Management of immune-related adverse events in patients treated with immune checkpoint inhibitor therapy: American Society of Clinical Oncology Clinical Practice Guideline.J Clin Oncol. 2018; 2018 (JCO2017z776385)https://doi.org/10.1200/JCO.2017.77.6385Crossref Scopus (1966) Google Scholar Whether or not the severity of the drug-induced liver injury reported in our case additionally relates to the extent of the underlying liver metastases (i.e. less viable liver tissue) requires further study.

Anti-thymocyte globulin has also been used to treat steroid-refractory immune-related hepatitis, but is limited to a small number of case reports.6Chmeil KD Suan D Liddle C Nankivell B Ibrahim R Bautista C et al.Resolution of severe ipilimumab-induced hepatitis after antithymocyte globulin therapy.J Clin Oncol. 2011; 29: e237-e240Crossref PubMed Scopus (115) Google Scholar, 7Spankuch I Gassenmaier M Tampouri I Noor S Forschner A Garbe C et al.Severe hepatitis under combined immunotherapy: Resolution under corticosteroids plus anti-thymocyte immunoglobulins.Eur J Cancer. 2017; 81: 203-205Abstract Full Text Full Text PDF PubMed Scopus (27) Google Scholar Ziemer and colleagues have also reported the successful use of budesonide (with ursodeoxycholic acid ± N-acteylcysteine) in 2 cases, in order to limit exposure to systemic corticosteroids and enable re-introduction of cancer immunotherapy[8]Ziemer M Koukoulioti E Beyer S Simon JC Berg T Managing immune checkpoint-inhibitor-induced severe autoimmune-like hepatitis by liver-directed topical steroids.J Hepatol. 2017; 66: 657-659Abstract Full Text Full Text PDF PubMed Scopus (46) Google Scholar. This approach is of interest, albeit it remains unclear whether it would be successful in patients with extensive liver metastases and jaundice. We, therefore, made the decision to use anti-TNFα, infliximab, for several reasons: (a) predominance of marked CD8+ T-cell lobular and necrotic hepatitis on histology, (b) prior experience with use in colitis[9]Geukes Foppen MH Rozeman EA van Wilpe S Postma C Snaebjornsson P van Thienen JV et al.Immune checkpoint inhibition-related colitis: symptoms, endoscopic features, histology and response to management.ESMO Open. 2018; 3e000278Crossref PubMed Scopus (165) Google Scholar and pneumonitis,[10]Nishino M Sholl LM Hodi FS Hatabu H Ramaiya NH Anti-PD-1 related pneumonitis during cancer immunotherapy.N Engl J Med. 2015; 373: 288-290Crossref PubMed Scopus (284) Google Scholar (c) marked progressive jaundice and (d) the urgent need for an anti-inflammatory response to prevent sub-acute liver failure, in a patient in whom liver transplantation was contraindicated. Interestingly, both the American Society of Clinical Oncology and the European Society for Medical Oncology guidelines advocate against the use of anti-TNFα in immune-related hepatitis, highlighting concern over idiosyncratic liver failure without citing evidence. There are no registered cases of infliximab-induced liver failure when used for immune-related colitis and infliximab has been used to reverse liver injury in a small case series of autoimmune hepatitis.[11]Weiler-Normann C Schramm C Quaas A Wiegard C Glaubke C Pannicke N et al.Infliximab as a rescue treatment in difficult-to-treat autoimmune hepatitis.J Hepatol. 2013; 58: 529-534Abstract Full Text Full Text PDF PubMed Scopus (159) Google Scholar In our case, infliximab did not result in any adverse liver events, sepsis or identifiable opportunistic infections. Escalating immunosuppression to prevent liver failure and chronic liver injury must be balanced against the risk of a life-threatening opportunistic infection and/or loss of immune control of the underlying malignancy. As in those with autoimmune hepatitis, resolution of liver injury may lag months behind LFT normalisation. Therefore, decisions around tapering immune suppression require informed agreement between hepatologist, oncologist and patient to guide risk management. Notably in our case, despite the use of systemic corticosteroids, MMF (albeit limited use), infliximab and then maintenance with monotherapy low dose tacrolimus, there was no progression of the underlying melanoma. This suggests that the very severe T-cell immune-related hepatitis reaction coincided with control of extensive hepatic malignancy (i.e. no metabolic activity) and it is plausible that they are associated. In the event of recurrent tumour metabolic activity, there are limited published data concerning re-treatment with checkpoint inhibitors, in particular PD1-inhibitors/combination therapy and the risk of IrAE re-manifestation. Abnormal LFTs occur in approximately a fifth of patients on combination immune checkpoint inhibitors for advanced malignancy. Early detection of liver injury by close laboratory monitoring of LFTs is thus a key part of caring for patients receiving checkpoint-inhibitor therapies. However, a small number of cases develop steroid-refractory, severe immune-related hepatitis. In the event of severe jaundice and progressive histological injury, we report the first successful, safe use of infliximab as a rescue therapy in a patient with life-threatening, checkpoint-inhibitor induced hepatitis.
