In the experience of our center, thalidomide was effective in achieving clinical remission in several children, adolescents, and young adults with intractable IBD. From 1998 to 2004 twenty-eight patients with refractory moderate-severe IBD (19 CD, 9 UC) received thalidomide 1.5-2.5 mg/kg/day. Remission was achieved with thalidomide in 21 of 28 (75%) patients (17 with CD, 4 with UC). Mean duration of remission was 34.5 months. Sixteen of 20 (80%) patients suspended steroids. Reversible neuropathy occurred in seven of 28 (25%) patients, but only with cumulative doses over 28 g. Other side effects requiring thalidomide suspension were vertigo/somnolence (one case), and agitation/ hallucinations (one case).
