Efficacy and Saafety of Omez Iin Patients With H.Pylori Associated Diseases

Study Overview
=================
Brief Summary
-----------------
Comparison of efficacy of H.pylori eradication during first line therapy using standard or high doses of omeprazole administered twice daily in combination with amoxicillin and clarithromycin for 10 days.

Detailed Description
-----------------
Rationale for the use of high doses of omeprozo la - 80 mg in the scheme of eradication therapy 1st line Intensive study of the microorganism Helicobacter pylori (H. pylori) Prodo l zhaetsya more than 30 years. Actively study the role of infection in the development and maintenance of chronic inflammation of the digestive system and especially its capabilities and elimin tion. In 1997, the first recommendations concerning diagnosis and were developed n infection, Helicobacter therapy indications for various embodiments and treatment of diseases associated with H. pylori. These guidelines are called first the Maastricht Treaty, or Maastricht-1 - the main document Regla and tail by the tactics of patients with H. pylori-associated ill and tions. In the future, in connection with obtaining new data on the properties of the causative agent, spreading disease, which occurs in H. pylori plays a pathogen is, genetically role, and the appearance of information on the effectiveness of different eras schemes and dikatsionnoy therapy recommendations were renegotiated, received sootvets t tively name Maastricht 2 (2000), and Maastricht-3 (2005). As antihelikoba to puter first line therapy authors agreement offer a combination of a proton pump inhibitor (or ranitidine bismuth citrate) in the standard dosage (OMe n Rasoli 20mg Lansoprazole 30 mg Pantoprazole 40 mg Rabeprazole 20 mg esomeprazole 20 mg) twice a day, in combination with clarithromycin (R) 500 mg twice daily and amoxicillin (a) 1000 mg twice a day or metronidazole (M) 500 mg twice a day for at least 7 days. Under the conditions commonly konstatiruemogo progressive growth of a microorganism resistance to most commonly used antibiotics, that it and nuemo reduces the efficiency of eradication (data along with 80-90% to 30-60% and even up to 12,5-18,3%) dictated the development of new recommendations for Dr. s processing of highly efficient schemes of eradication therapy [1, 2]. The recommendations of the last convocation of experts presented at the XXIV International with e nar on the role of Helicobacter and related bacteria in the development of chronic e tion of inflammation of the digestive tract and stomach cancer (Symposium Maastricht-4 on 13 September 2011, Dublin, Ireland) [3] . The methods of increasing the effectiveness of eradication therapy, according to this claim about the recent agreement includes the use of high (4-fold) doses of PPI, SW e crease the duration of therapy to 10-14 days (increases the effectiveness of treatment at 5%), the use of probiotics and prebiotics as adjuvant therapy [3, 4, 5,6]. Increasing doses of PPIs increases the concentration of drug in the blood, and consequently s but increases the antisecretory effect. When using high doses of drugs of this group in the eradication schemes, serious side effects have not time in h penetrate due to a short course of taking the drugs [7]. The present study is designed to investigate the efficacy and bezop with of high doses of PPIs in the schemes of eradication in terms of Maximal s tion efficiency of therapy of H. pylori.
