BACKGROUND/AIMS: We evaluated the efficacy of mesalamine (Asacol) in reducing gastrointestinal symptoms after an acute attack of diverticulitis. METHODS: This was a 1-year double-blind, randomized, placebo-controlled study in which patients with computed tomography scan confirmed acute diverticulitis receivedplacebo, mesalamine, or mesalamine+Bifidobacterium infantis 35624 (Align) for 12 weeks and followed for 9 additional months. Efficacy was assessed using a global symptom score (GSS) of 10 symptoms (abdominal pain, abdominal tenderness, nausea/vomiting, bloating, constipation, diarrhea, mucus, urgency, painful straining, and dysuria). Patients were required to have a GSS≥12 at baseline, including an abdominal pain score >2. RESULTS:One hundred seventeen patients (placebo, 41; mesalamine, 40; mesalamine+probiotic, 36) were randomized and treated. GSS decreased in all groups during treatment without a statistically significant difference between mesalamine and placebo, however; scores were consistently lower for mesalamine at all time points. The rate of complete response (GSS=0) was significantly higher with mesalamine than placebo at weeks 6 and 52 (P<0.05), and was particularly high for rectosigmoid symptoms at weeks 6, 12, 26, and 52. Recurrence of diverticulitis was low and comparable across groups. Probiotic in combination with mesalamine did not provide additional efficacy. CONCLUSIONS: In the first US randomized placebo-controlled trial of anti-inflammatory treatment after a documented case of diverticulitis, mesalamine demonstrated a consistent trend in reducing symptoms. Addition of probiotic did not increase mesalamine efficacy. This study supports further investigation into the use of anti-inflammatory agents, such as mesalamine, in the long-term management of diverticulitis. ClinicalTrials.gov NCT00554099.
