MANAGEMENT FOR H.PYLORI ERADICATION It is known that H.pylori infection is associated with over 90% of duodenal ulcers and 80% of Gastric Ulcers. Antibiotics alone or acid-suppressing agents alone, do not eradicate H.pylori . Both therapies act synergistically as growth of the organism occurs at elevated pH and antibiotics efficacy is enhanced during growth. Additionally, increasing intragastric pH may enhance antibiotic absorption. High eradication rates are achieved by a short course of Triple Therapy consisting of:            1 .PPI                                         2. Clarithromycin                         3. Amoxicillin/Metronidazole          in a twice recommended simultaneous regimen. First-Line Therapy :  European Guidelines recommended 1 week of therapy, whereas the US Guidelines recommend 10-14 days of therapy and achieve 7-9% better eradication rates.     OCA : Omeprazole(20mg), Clarithromycin (500mg) and Amoxicillin (1g)                                         

 PEPTIC ULCER Clinical Manifestations: Upper abdominal pain; occurring 1-3hour after meals and relieved by food or antacids in the classic symptom of peptic-ulcer disease. Anorexia Weight loss Nausea Vomiting Heartburn Hemorrhage Chronic-iron deficiency anemia Pyloric stenosis Perforations In the elderly, the presentation is more likely to be silent and gastro-intestinal bleeding may be the first clinical sign of disease. Patient Assessment: Presenting symptoms of dyspepsia require careful assessment to judge the risk of serious disease or to provide appropriate symptomatic treatment.      1.Reflux-like dyspepsia: Heartburn plus dyspepsia Acid regurgitation plus dyspepsia       2. Ulcer-like dyspepsia:  Localized epigastric  pain. Pain when hungry Pain relieved by  food. Pain relieved by antacids or acid-reducing  drugs. Pain that wakens the patient from sleep Pain with remission and relapse       3. Dysmotility-like Dyspepsia: Upper abdominal discomfort (pain not dominant) Early sati

 PEPTIC ULCER Definition: "The term Peptic Ulcer describes a condition in which there is a discontinuity in the entire thickness of the gastric or duodenal mucosa, that persists as a result of acid and pepsin in the gastric juice." Esophageal ulceration due to acid reflux, is generally classified under GERD. Peptic ulcer disease often presents to clinicians as dyspepsia. However, not all patients with dyspepsia have peptic ulcer disease. " Dyspepsia " is defined as persistent or recurrent pain or discomfort centered in the upper abdomen.  The most common causes of dyspepsia include: non-ulcer or functional dyspepsia GERD Peptic ulcer Epidemiology: The incidence of duodenal ulcer is now declining, which follows the decline H.Pylori infection. However, hospital admission rates for gastro-intestinal bleeding associated with gastric and duodenal ulcers are rising. This is probably a consequence of increased prescription for low-dose aspirin, NSAIDs, Antiplatelets, anti
