The use of Cyclosporin A in acute steroid-refractory ulcerative colitis: long term outcomes

Approximately 15% of patients with ulcerative colitis will have a severe flare requiring hospitalisation at some stage. For those who fail to respond to intravenous steroids Cyclosporin A (CyA) therapy is one option. We have evaluated the management of such patients in our centre and present the long term colectomy avoidance rates.

38 consecutive patients receiving CyA for an acute, steroid-refractory flare of colitis were retrieved from our database. Records were unavailable for 2 patients and 2 received therapy twice, hence 38 episodes were analysed.

24/36 patients were male; median age 37 years. On admission 20 patients were taking oral steroids; 8 were taking a thiopurine and 7 patients were on no treatment. CyA was started a median of 8 days after admission (range 1-28) and most patients (32/38) received this orally at doses of 4.5-8.3mg/kg. 15 patients have undergone colectomy, 11 of these during the same admission for lack of response to CyA. Of the patients who were discharged without surgery, 84% have still not required colectomy after a median follow-up of 3.8 years. Adverse effects were mostly minor, though two patients developed neutropenia on dual immunosuppression.

CyA can be administered orally with good tolerability. We use it as a bridging therapy to Azathioprine. In our population, 84% of those who responded to CyA have not required surgery.
