A curcumin-based 1-week triple therapy for eradication of Helicobacter pylori infection: something to learn from failure?

BACKGROUND: Curcumin is the principal element of turmeric powder extracted from the root of Curcuma longa. Studies on curcumin have demonstrated some anti-Helicobacter pylori activity as well as immunomodulating properties. N-acetylcysteine and lactoferrin with their respective mucolytic and antibacterial activities might also be effective in H. pylori eradication therapy. AIM: To determine if a 7-day non-antibiotic therapy comprised of curcumin, lactoferrin, N-acetylcysteine, and pantoprazole was effective for eradication of H. pylori infection and reduction of gastric inflammation, assessed by serum pepsinogens and relief of symptoms. SUBJECTS AND METHODS: Twenty-five consecutive H. pylori-positive patients (12 males, mean age 50 +/- 12 years, range 31-76) with functional dyspepsia were enrolled. Patients were administered for 7 days curcumin 30 mg b.i.d., bovine lactoferrin 100 mg b.i.d., N-acetylcysteine 600 mg b.i.d., and pantoprazole 20 mg b.i.d. H. pylori status and upper gastrointestinal symptoms were assessed by (13)C-urea breath test and a scale of upper gastrointestinal symptoms intensity (absent, mild, moderate, and severe), as well as a blood test for serum pepsinogens (sPGI, sPGII), gastrin-17 (G-17), and anti-H. pylori IgG (IgG-Hp) at baseline (T0) and after 2 months (T1). RESULTS: Three of 25 patients (12%) were cured of H. pylori infection. A significant decrease in the overall severity of symptoms (T0: 6, interquartile range [IQR]: 4.5-8; T1: 2, IQR: 2-3; p < or = .001), and sPGII (T0: 16 microg/L, IQR: 13-22; T1: 10 microg/L, IQR: 8-16; p < or = .001) and sPGI (T0: 82 microg/L, IQR: 67-97; T1: 74 microg/L, IQR: 62-94; p = .02) levels were observed after 2 months of the treatment. IgG and G-17 values did not significantly decrease after 2 months. CONCLUSIONS: This novel therapy was not effective for H. pylori eradication. However, despite the bacterium persistence, significant improvement of dyspeptic symptoms and reduction of serologic signs of gastric inflammation were observed after 2 months at the end of the 7-day treatment schedule.

Prevention of complications and symptomatic recurrences in diverticular disease with mesalazine: a 12-month follow-up.

In uncomplicated diverticular disease, treatment is aimed at relieving symptoms. The aim of the present study was to evaluate the efficacy of mesalazine for symptomatic relief of uncomplicated diverticular disease of the colon. Two hundred sixty-eight consecutive eligible outpatients (122 male, 146 female; age, 66.1 years; range, 31-81 years) were enrolled in four treatment schedules in a randomized fashion: Group R1 (66 patients), rifaximin, 200 mg bid; Group R2 (69 patients), rifaximin, 400 mg bid; Group M1 (67 patients), mesalazine, 400 mg bid; and Group M2 (66 patients), mesalazine, 800 mg bid. Treatments were administered for 10 days every month for 12 months. Clinical evaluations were performed at admission and at 3-month intervals for 12 months considering 12 clinical variables (upper and lower abdominal pain/discomfort, tenesmus, diarrhea, abdominal tenderness, fever, bloating, general illness, nausea, emesis, dysuria, bleeding) graded as 0 = no symptoms, 1 = mild, 2 = moderate, and 3 = severe. The Global Symptomatic Score (GSS) was calculated using the sum of each symptom score. Two hundred forty-four patients completed the 12- month study; 24 were discontinued (14 treated with rifaximin and 10 treated with mesalazine) either as voluntary dropouts or because they developed side effects and/or complications. Group M2 demonstrated a lower frequency of many symptoms after 6 and 12 months of treatment; the mean GSS was significantly lower in Group M2 after 6 and 12 months of therapy by both intention-to-treat and per-protocol analyses. Patients treated with mesalazine (Groups M1+M2) had a lower GSS than subjects treated with rifaximin (Groups R1+R2) during the 12-month follow-up period. We conclude that cyclic administration of mesalazine is effective for symptomatic relief of uncomplicated diverticular disease of the colon. Some symptoms showed greater improvement with mesalazine, 800 mg bid, than with the other treatment schedules.

Surgical results and functional outcome after total anorectal reconstruction by double graciloplasty supported by external-source electrostimulation and/or implantable pulse generators: an 8-year experience.

BACKGROUND AND AIMS: Surgical and functional results after abdominoperineal resection and total anorectal reconstruction by electrostimulated gracilis muscle transposition are still poorly documented. This study prospectively evaluated surgical and functional outcome over time in our patients. PATIENTS AND METHODS: Twenty-three patients underwent abdominoperineal resection, coloperineal pullthrough, double graciloplasty, and loop abdominal stoma. Temporary external-source intermittent electrostimulation, biofeedback training, and selective delayed stimulator implantation to improve unsatisfactory results were carried out in the first 13 patients (1st series); thereafter (2nd series) the stimulator was implanted during graciloplasty. Surgical and oncological results were followed up in all patients. Functional results were evaluated in 16 patients who underwent abdominal stoma takedown, eight in each of the two series, by anomanometry (up to 1 year) and our own 0-20 scoring system (up to 8 years from initial surgery). RESULTS: The rate of major and minor postoperative complications was 21.7% and 65%, respectively. Continuous electrostimulation proved effective on resting anal pressure. Early clinical assessments showed satisfactory functional results (considered as having a score < or =8) in all first-group patients, including five who had stimulator support, and in one-half of second-group patients. After impairment (at least 2 points) at 1 year in five patients, four of whom were from the first group, all functional results improved and became satisfactory from 5 years on (1st series) and from 4 years on (2nd series). CONCLUSION: Despite marked morbidity the high rate of good results, which improved over time, suggests that total anorectal reconstruction is worth being performed as part of abdominoperineal resection in well-selected patients with a strong motivation to avoid a permanent colostomy.
