Article: Bovine lactoferrin for Helicobacter pylori eradication: an open, randomized, multicentre study.
[show abstract] [hide abstract]
ABSTRACT: Cure rates for eradication of Helicobacter pylori appear to be decreasing, thus more effective therapies must be identified. To evaluate the efficacy of bovine lactoferrin in the treatment of H. pylori infection. In a multicentered prospective study, 402 (mean age 52.4, range 19-84 years) H. pylori-positive patients were assigned to one of three regimens: group A - esomeprazole 20 mg b.d., clarithromycin 500 mg b.d. and tinidazole 500 mg b.d. for 7 days; group B - lactoferrin 200 mg b.d. for 7 days followed by the same schedule of group A; group C - esomeprazole 20 mg b.d., clarithromycin 500 mg b.d. and tinidazole 500 mg b.d. plus lactoferrin 200 mg b.d. for 7 days. Of the 402 patients, 389 completed the study. Six patients were discontinued due to side effects, one patient in group B died and six patients were lost to follow up. The eradication rate (intention-to-treat analysis) was 77% in group A (105/136), 73% in group B (97/132) and 90% in group C (120/134) (chi(2)-test P < 0.01). The incidence of side effects was 9.5% in group A, 9% in group B and 8.2% in group C (chi(2)-test P = 0.1). This study demonstrates that bovine lactoferrin is an effective adjuvant to 7-day triple therapy for eradication of H. pylori infection.Alimentary Pharmacology & Therapeutics 04/2006; 23(8):1235-40. · 3.77 Impact Factor -
Article: Clinical usefulness of serum pepsinogens I and II, gastrin-17 and anti-Helicobacterpylori antibodies in the management of dyspeptic patients in primary care.

ABSTRACT: Several tests have been proposed for evaluating dyspeptic symptoms and their relationship to the underlying gastric disease. Serum pepsinogens and gastrin-17 are known to be useful biomarkers for the detection of gastric pathologies. To evaluate the capability of screening dyspeptic patients in the primary care by analyses of serum pepsinogens I (sPGI) and II (sPGII), gastrin-17 (sG-17) and the IgG anti-Helicobacter pylori antibodies (IgG-Hp). Three hundred and sixty-two consecutive patients with dyspeptic symptoms (208 females, mean age 50.6 +/- 16 years, range 18-88 years) referred by general practitioners for upper gastrointestinal endoscopy were enrolled. A blood sample was taken from each subject for IgG-Hp, sPGI, sPGII and sG-17 analyses. Two hundred and eighty-seven patients had a complete screening; of these, 132 resulted positive for Hp infection. Patients with atrophic chronic gastritis showed significantly lower serum pepsinogen I levels and sPGI/sPGII ratio than patients with non-atrophic chronic gastritis. Moreover, by calculating the values of sPGI by sG-17 and sG-17 by sPGII/sPGI, subjects with atrophic chronic gastritis could be distinguished from those with non-atrophic chronic gastritis and from those with normal mucosa, respectively. sG-17 levels were found to be a useful biomarker for the detection of antral atrophic gastritis, while the combination of sPGI, the sPGI/sPGII ratio and sG-17 was found effective in identifying corpus atrophy. A panel composed of PGI, PGII, G-17 and IgG-Hp could be used as a first approach in the 'test and scope' and/or 'test and treat' strategy in the primary care management of dyspeptic patients.Digestive and Liver Disease 08/2005; 37(7):501-8. · 3.05 Impact Factor -
Article: Use of bovine lactoferrin for Helicobacter pylori eradication.
[show abstract] [hide abstract]
ABSTRACT: One-week triple therapy is the most frequently recommended treatment for Helicobacter pylori infection. Eradication rate is satisfactory, nevertheless is advisable to look for more effective therapies. To test the efficacy of a standard triple therapy plus bovine lactoferrin in the eradication of H. pylori infection. One hundred and fifty consecutive H. pylori positive patients, suffering from dyspeptic symptoms were recruited in a 7-day triple therapy open randomised single centre study with rabeprazole, clarithromycin, tinidazole, bovine lactoferrin (group A) or rabeprazole, clarithromycin, tinidazole (group B), or a 10-day therapy with rabeprazole, clarithromycin, tinidazole (group C). H. pylori status was assessed 8 weeks after the end of the treatment by means of a 13C-urea breath test or a H. pylori stool antigen-test. Eradication rates (intention to treat/per protocol) were: group A (92.2/95.9%), group B (71.2/72.5%) and group C (70.2/75%). The efficacy of triple therapy added with lactoferrin was significantly higher than other two regimens (p=0.01, intention to treat analysis; p=0.005, per protocol analysis). These results suggest that lactoferrin tested in the present study was effective in curing H. pylori and could be a new agent to assist the antimicrobials in the eradication of the bacterium.Digestive and Liver Disease 11/2003; 35(10):706-10. · 3.05 Impact Factor
