Cyclosporine A for refractory interstitial cystitis/bladder pain syndrome: experience of 3 tertiary centers.
OBJECTIVE
Cyclosporine A is a fifth-tier treatment option in the American Urological Association guidelines for interstitial cystitis/bladder pain syndrome. It was more effective than pentosanpolysulfate in a Finnish trial, but experience elsewhere is limited. Some centers use cyclosporine A off label for carefully selected patients but the number of patients in each center is small. We performed a retrospective review combining data from 3 tertiary centers that focus on interstitial cystitis/bladder pain syndrome.


METHODS
Charts were reviewed for patients with interstitial cystitis/bladder pain syndrome who received cyclosporine A. Response was defined as markedly improved on the 7-point global response assessment (2 centers) or as at least a 50% decrease in Interstitial Cystitis Symptom Index score (1 center).


RESULTS
The study included 14 men and 30 women. Mean patient age was 55.5 years (range 27 to 75) and mean followup was 20.8 months (range 3 to 81). A total of 34 patients had Hunner lesions. Of these patients 29 (85%) responded but 6 eventually stopped cyclosporine A for adverse events, resulting in a success rate of 68% (23 of 34) for patients with Hunner lesions. In contrast, only 3 of 10 patients without Hunner lesions responded (30%). For all responders, the response occurred within 4 months.


CONCLUSIONS
Cyclosporine A had a high success rate for patients with Hunner lesions in whom more conservative options, including endoscopic treatment, had failed. The success rate was low for patients without Hunner lesions. A 3 to 4-month trial is sufficient time to assess response. Adverse events were common and led to discontinuation of cyclosporine A for some patients. Close monitoring is needed, especially for blood pressure and renal function.
