IN RESPONSE:
The cause of collagenous colitis is unknown. Proposed pathogenic mechanisms include luminal toxicity, especially of gluten [1], an inflammatory process, and a primary defect in collagen turnover. As discussed by Kingham and colleagues [2] and Stampfl and coworkers [3] stimulation of collagen production by inflammation might be enhanced by coexistence of a defect in the regular control of collagen synthesis, such as scleroderma. We agree with Dr. Sowa that collagenous colitis and arthritis may be associated with gold toxicity. However, our patient had never received gold therapy at any time, and we believe that the association with lupus argues for an inflammatory origin. We must add that although none of the seven patients reported by Giardello and coworkers [4] had arthritis, the authors did discuss the relation between collagenous colitis and rheumatoid disease.
