The aim of the present study was to evaluate the safety and efficacy of 6-TG in patients with ulcerative colitis (UC) or indeterminate colitis (IC) intolerant or resistant to AZA/6-MP. Material and methods. Twenty patients with an acute flare, steroid-dependent or steroid-refractory disease attending our outpatient department were included in the study. Measurement of 6-TG nucleotide levels was done to check compliance. Complete, partial and non-response were defined by means of the clinical activity index and the daily steroid demand. Secondary outcome parameters included changes in cumulative steroid doses, C-reactive protein (CRP) levels, and an endoscopic score. Results. Out of 20 patients 4 were excluded owing to incompliance; 2/16 compliant patients (13% ) had to be prematurely withdrawn because of adverse events, which ceased upon drug discontinuation. By per-protocol analysis, 5/14 patients (36% )were complete, 6/14 (43% ) partial and 3/14 (21% ) non-responders. In addition to the reduction of the cumulative steroid dose over 3 months, CRP decreased in the study population and the endoscopic score decreased in treatment responders. Conclusions. Treatment with 6-TG was effective in patients with UC or IC previously intolerant or resistant to AZA/6-MP. Future work is needed to define a subpopulation of patients at low risk for its potential hepatotoxicity, which we assume will benefit from 6-TG. | Teml A. Schwab M. Harrer M. W.
