Abstract
Forty patients with Graves' ophthalmopathy stages III–V were divided into two groups in a random manner according to their year of birth. Group I received prednisone in decreasing dosage. Group II received prednisone at a comparable dosage and ciclosporin. Steroids were discontinued after 10 weeks in the two groups. In the patients of group II, ciclosporin was continued over 12 months. The therapeutic effect was assessed by an activity score based on subjective and objective symptoms (computerized tomography and sonography of the orbit, Hertel values, clinical findings). All signs of endocrine ophthalmopathy improved significantly in both groups (P less than 0·01 in group I; P less than 0·001 in group II). The improvement was significantly greater in group II (P less than 0·05) according to the predefined score. After corticosteroids were discontinued, inflammatory signs recurred in nine patients in group I and in one of group II. During the observation period of 12 months, relapses occurred in eight out of twenty patients in group I and in only one out of twenty in group II. Muscle thickness decreased in nine patients in group II, 6 months after beginning therapy. At this time, the results were not influenced in any of the twenty patients in group I. Microsomal antibodies decreased significantly (P less than 0·001) in the ciclosporin group, whereas no change was seen in the other group. Renal values rose within the normal range in group II. In this group, an infection with Klebsiella pneumoniae occurred in one patient after 4 months of therapy. A rebound phenomenon after stopping ciclosporin has not yet been observed. Thus the drug ciclosporin proved to be effective both in terms of improvement of the acute effect as well in relapse prophylaxis of Graves' ophthalmopathy.
