Efficacy of a new nutraceutical formulation: L-tryptophan, probiotics, charcoal, chamomile, mint, and licorice (COLONIR®) in the improvement of gastrointestinal symptoms in subjects with irritable bowel syndrome.

BACKGROUND: Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders. IBS is characterized by recurrent chronic abdominal pain and altered bowel habits in the absence of organic damage. Although there are reviews and guidelines for treating IBS, the complexity and diversity of IBS presentation make treatment difficult. Treatment of IBS focuses on relieving symptoms as mild signs and symptoms can often be controlled by managing stress and by making changes in diet and lifestyle. The use of nutraceutical compounds has been advocated as a possible alternative treatment in patients with IBS. COLONIR® (Omega Pharma Srl, Milan, Italy) may be an alternative or adjuvant treatment in patients with gastrointestinal symptoms. This study aimed to evaluate the effect of this new nutraceutical formulation in inducing symptoms remission and improve gastrointestinal habits. METHODS: An initial cohort of 1004 consecutive patients referred to 25 different Units of Internal Medicine a/o Gastroenterology in Italy to perform colonoscopy for intestinal symptoms was asked to participate. Patients were treated for 2 months with two doses of nutraceuticals/day during meals namely COLONIR®. Patients were assessed at baseline and after 2 months to evaluate the frequency and severity of gastrointestinal symptoms in the past seven days with a questionnaire based on ROMA IV criteria. RESULTS: After 2 months, 899 patients completed the follow-up. COLONIR® achieved a statistically significant reduction of severity of symptoms in the study population without any documented side effects. CONCLUSIONS: These promising results, here reported, need to be confirmed, valuating the efficacy of COLONIR® in relieving gastrointestinal symptoms in IBS patients in further studies.

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.

Natural course of functional dyspepsia after Helicobacter pylori eradication: a seven-year survey.

The role of Helicobacter pylori(Hp) in functional dyspepsia (FD) is controversial and previously published data do not help to clarify whether Hp eradication affects the natural course of FD. The aim of this study was to assess the clinical course of FD during a long follow-up period of 7 years in a homogeneous sample of Hp-eradicated patients. Among patients referred between 1991 and 1996, patients with FD and infected with Hp were enrolled. Patients were administered a structured symptom questionnaire and evaluated after Hp eradication at each 12-month time points. Patients were divided into three FD subgroups: predominantly ulcer-like, dismotility-like, and reflux-like symptom clusters. A composite symptom score ranging from 0 (no symptom) to 3 (severe symptoms) was assigned to each FD cluster. Of the 1685 screened patients, 405 had FD and 211 of them (52.1%) were also Hp-positive. During the follow-up, the amount of missing information varied from 10% to 17.5% within the first 6 years and was 30.8% at 7 years. The rates of improved patients ranged from 33% (reflux-like) to 34.9% (dismotility-like) to 47.3% (ulcer-like). However, only a proportion of 10%-50% of them was symptom-free after eradication and also at each 12-month evaluation, whereas the other patients became symptomatic at different times. FD symptoms slightly improve after Hp eradication over a long period of time but a large percentage of these improved patients may experience FD symptoms again, even after some years of well-being after Hp eradication.

[Analysis of the problem of "difficult hospital discharges" in the University Hospital of Parma]. / Analisi del problema "dimissioni difficili" nell'Azienda Ospedaliera-Universitaria di Parma.

We analyzed, in a middle-sized hospital, the problems related to the so-called "difficult discharges", conceived as situations involving an economic, human and organizational burden exceeding patients' and their families' capacities and requiring a specific involvement of territorial services. During a whole year (July 1, 2001-June 30, 2002) the cases found were 591. We demonstrated that the problem concerns mainly elderly patients, almost equally distributed between males and females, a quarter of the sample being represented by patients who had recently undergone surgery and whose discharge difficulties were mostly related to mixed social and sanitary problems. This kind of patients is faced with long-term hospitalization implicating a large number of intra-hospital transfers due to the presence of severe and disabling pathologies, mainly neoplasms and strokes, often associated with other serious diseases, various complications and difficult situations from the health point of view. About half of the patients had the possibility to go back home, while the rest required lodging in territorial structures such as nursing homes and retirement homes. The average time-lapse between the possible discharge indicated by the hospital physician and the actual discharge was 10 days, with global annual 6106 days of "improper" hospitalization. Our conclusion is that the phenomenon of difficult discharges is nowadays a very topical problem and that it should be faced with a new model of continuous and integrated assistance organization.
