Severe bone pain as an adverse effect of cyclosporin therapy for Crohn's disease

Abstract: A case of severe bone pain associated with cyclosporin therapy for Crohn's disease is reported. Severe leg pain developed in a 32-year-old man who was receiving cyclosporin for Crohn's disease that was refractory to medical management. Leg pain was related to the dose of cyclosporin, improved with calcium channel blockade, and resolved on discontinuation of cyclosporin. This syndrome has been described in the renal transplantation literature and may be related to vasoconstriction of bone vasculature.

“…Cytomegalovirus (CMV) antigen was found in a peripheral blood buffy coat, and th patient's symptoms resolved within 24 hours of starting IV ganciclovir 10 mg/kg/d. Isaacs [19] described a similar clinical presentation in a patient being treated with CSA and prednisone who had a negative examination and x-ray. The patient was then treated successfully with nifedipine on the assumption that the sudden pain was caused by cortical bone vasoconstriction, as had been previously described in the renal transplantation literature.…”

“…It has been described in patients following renal transplant and other solid organ transplantation. There have also been cases described with psoriatic arthritis and Crohn's disease where cyclosporin was used [3].…”

“…So far, the etiology of the syndrome is still controversially discussed [36]. Of further note is the fact that bone pain syndromes caused by bone marrow edema related to cyclosporine medication have also been described in clinical settings different from transplantation [37], thus raising the probability of CNI‐medication as at least one major etiologic agent in the development of the syndrome. As the syndrome displays a benign and time‐limited course in patients with an acceptable graft function on long‐term follow up, we would only cautiously suggest conversion to a less immunosuppressive protocol.…”
