Cyclosporine on par with infliximab for severe colitis

The advent of checkpoint inhibitor therapy in medical oncology has led to an increase in hospitalizations for immune-related adverse effects. Severe colitis has been reported in approximately 5% of patients treated with cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) inhibitors, such as ipilimumab. Standard management for those with severe colitis includes administration of systemic corticosteroids with the reservation of antitumor necrosis factor (anti-TNF) therapy, such as infliximab, if there has been no improvement. Rarely, immunotherapy-induced colitis can become life-threatening and result in bowel perforation requiring surgical intervention. Yet, there are no specific recommendations for medical management following colectomy in these situations. In cases of severe colitis from Crohn’s disease, postoperative treatment with infliximab has been found to be safe when administered shortly after intestinal resection. However, there remains limited data to support administration of infliximab following bowel perforation due to immunotherapy-induced colitis. Our case illustrates management of a severe adverse reaction to checkpoint inhibitor therapy and the need to further evaluate the role of infliximab postoperatively in patients who develop colitis complicated by bowel perforation.

Severe Colitis

A 48-year-old woman presented with severe abdominal pain, bilious vomiting and bloody diarrhoea for 1 day. On examination, she was haemodynamically unstable, febrile and clinically had an acute surgical abdomen. She had markedly raised inflammatory markers, neutrophils and deranged renal function. A CT abdominal scan revealed severe colitis and thickening throughout the length of the colon. The patient was stabilised and underwent emergency laparotomy resulting in total colectomy and end ileostomy formation. Postoperatively, she required several units of human albumin solution, red blood cell transfusions and octaplex (prothrombin complex) to prevent further bleeding. An inpatient haematology review revealed a hypocomplementaemia (C3/C4), low immunoglobulin (IgG, IgM, IgA) and peripheral blood films revealed schistocytosis indicating microangiopathic haemolytic anaemia. Bowel histology supported this, demonstrating circumferential lymphocytic phlebitis with thrombi and mucosal haemorrhage, necrosis and ulceration. The patient went on to suffer multiple ischaemic strokes before undergoing plasmapheresis, subsequent rehabilitation and making a successful recovery.
