RESUMO
BACKGROUND: 6-Mercaptopurine is often used as maintenance therapy in patients with Crohn's disease. However, toxicities like myelosuppression limit its clinical benefit. AIMS: To evaluate the efficacy of elemental diet versus 6-mercaptopurine as maintenance therapy in Crohn's disease. METHODS: Ninety-five eligible patients with Crohn's disease activity index ≤150 were randomly assigned to: 6-mercaptopurine (0.5-1.5mg/kg/day, n=30); Elental as an elemental diet (≥900 kcal/day, n=32); none (control, n=33). In the three groups, patients were and remained on 5-aminosalicylic acid (2250-3000 mg/day). Patients were observed for 2 years and the rate of relapse (Crohn's disease activity index ≥200) was monitored. RESULTS: At 24 months, the fractions of patients who had maintained remission were 60%, 46.9% and 27.2% for 6-mercaptopurine, Elental and the control groups, respectively. Log-rank test showed better efficacy for 6-mercaptopurine (P=0.0041) and Elental (P=0.0348) versus control. No significant difference was found between 6-mercaptopurine and Elental. Further, in the 6-mercaptopurine group, 2 patients experienced liver injury and one developed alopecia. CONCLUSIONS: This 24 months comparison study showed that Elental as maintenance therapy in Crohn's disease patients was as effective as 6-mercaptopurine. Elental should be useful for long-term maintenance therapy in Crohn's disease. This is the first comparison study evaluating nutritional therapy versus 6-mercaptopurine.

An 81-year-old man who had under gone two abdominal surgeries and temporary colostomy 30 years previously was admitted due to lower abdominal pain and vomiting. An abdominal X-ray film and abdominal CT scan showed intestinal distension and multiple calcareous deposits in the colon. Gastrografin enema examination revealed smooth stenosis at the sigmoid colon and many additional defects. Endoscopy could not be performed due to the stenosis. He did not agree to surgery. Seven months later, he was admitted again, due to colonic obstruction. Surgery was performed which revealed colonic obstruction as the source of post-operative stenosis of the sigmoid colon and multiple enteroliths. The stones consisted of a core and a hull and contained ammonium magnesium phosphate.

BACKGROUND & AIMS: Curcumin is a biologically active phytochemical substance present in turmeric and has pharmacologic actions that might benefit patients with ulcerative colitis (UC). The aim in this trial was to assess the efficacy of curcumin as maintenance therapy in patients with quiescent ulcerative colitis (UC). METHODS: Eighty-nine patients with quiescent UC were recruited for this randomized, double-blind, multicenter trial of curcumin in the prevention of relapse. Forty-five patients received curcumin, 1g after breakfast and 1g after the evening meal, plus sulfasalazine (SZ) or mesalamine, and 44 patients received placebo plus SZ or mesalamine for 6 months. Clinical activity index (CAI) and endoscopic index (EI) were determined at entry, every 2 months (CAI), at the conclusion of 6-month trial, and at the end of 6-month follow-up. RESULTS: Seven patients were protocol violators. Of 43 patients who received curcumin, 2 relapsed during 6 months of therapy (4.65%), whereas 8 of 39 patients (20.51%) in the placebo group relapsed (P=.040). Recurrence rates evaluated on the basis of intention to treat showed significant difference between curcumin and placebo (P=.049). Furthermore, curcumin improved both CAI (P=.038) and EI (P=.0001), thus suppressing the morbidity associated with UC. A 6-month follow-up was done during which patients in both groups were on SZ or mesalamine. Eight additional patients in the curcumin group and 6 patients in the placebo group relapsed. CONCLUSIONS: Curcumin seems to be a promising and safe medication for maintaining remission in patients with quiescent UC. Further studies on curcumin should strengthen our findings.
