Collagenous colitis: possible response to sulfasalazine and local steroid therapy.

A patient with rheumatoid arthritis and collagenous colitis apparently responding to sulfasalazine and prednisolone enemas is reported. It is suggested that this form of therapy should be considered in patients with this rare disorder not only as a short-term measure but also, in the case of sulfasalazine, as long-term treatment in patients with chronic symptoms.
