Gastroesophageal reflux disease (GERD) is a common chronic disease in the older population. Because of the cumulative effects of acid reflux over many years, older patients with GERD are at increased risk of complications such as esophagitis, peptic strictures, and Barrett's esophagus. Early endoscopy is indicated for all older patients with GERD, irrespective of their symptoms. Medical and surgical treatment options for GERD and its complications can provide excellent symptom relief and healing of esophagitis. Three management approaches--step up, step down, and the directed approach--are recognized guides to clinical decision-making.

Nonerosive reflux disease is defined as the presence of typical symptoms of gastroesophageal reflux disease caused by intraesophageal acid in the absence of visible esophageal mucosal injury at endoscopy. Recent studies demonstrate that it is a chronic disease with a significant impact on quality of life, and it is very common in primary care settings. Treatment with acid inhibitory agents is effective, and proton pump inhibitors are the most effective form of therapy.

Gastroesophageal reflux disease (GERD) is a common disease increasing in incidence and prevalence in the industrialised countries. It is a chronic disease with a large spectrum of clinical manifestations. The leading symptom is heartburn, however the disease may also present with extraesophageal symptoms or stay asymptomatic. Motility disorders of the upper GI tract with the key feature of impaired LES are the cause for pathologic gastroesophageal reflux in the terminal esophagus. The relationship of H. pylori infection with GERD is part of the current discussion. The Savary Miller classification for grading of refluxesophagitis is now proposed for substitution by the Los Angeles classification for the assessment of erosive lesions. Besides complications such as bleeding or strictures the main risk is the development of Barrett esophagus and adenocarcinoma. Proton pump inhibitors are the therapy of choice for healing as well as in longterm therapy and prophylaxis. New endoscopic interventional therapies for treatment of GERD and related diseases should be used only in controlled studies.

Over the past decade, medical and surgical approaches to the patient with gastroesophageal reflux disease (GERD) have improved dramatically. Proton pump inhibitors have become the dominant medical therapy because of their high efficacy and safety. Laparoscopic surgical approaches have improved concomitantly with the advances in medical therapy, resulting in the perception that either continuous medical therapy or surgery are appropriate options for long-term maintenance of this chronic disorder. Recent approval of new endoscopic treatments for GERD has generated considerable interest, but acceptance of these techniques should be limited by the small number of patients studied to date, the lack of placebo controls, and the short duration of follow-up.

Lansoprazole is an inhibitor of gastric acid secretion and also exhibits antibacterial activity against Helicobacter pylori in vitro. Current therapy for peptic ulcer disease focuses on the eradication of H. pylori infection with maintenance therapy indicated in those patients who are not cured of H. pylori and those with ulcers resistant to healing. Lansoprazole 30 mg combined with amoxicillin 1g, clarithromycin 250 or 500mg, or metronidazole 400 mg twice daily was associated with eradication rates ranging from 71 to 94%, and ulcer healing rates were generally >80% in well designed studies. In addition, it was as effective as omeprazole- or rabeprazole-based regimens which included these antimicrobial agents. Maintenance therapy with lansoprazole 30 mg/day was significantly more effective than either placebo or ranitidine in preventing ulcer relapse. Importantly, preliminary data suggest that lansoprazole-based eradication therapy is effective in children and the elderly. In the short-term treatment of patients with gastro-oesophageal reflux disease (GORD), lansoprazole 15, 30 or 60 mg/day was significantly more effective than placebo, ranitidine 300 mg/day or cisapride 40 mg/day and similar in efficacy to pantoprazole 40 mg/day in terms of healing of oesophagitis. Lansoprazole 30 mg/day, omeprazole 20 mg/day and pantoprazole 40 mg/day all provided similar symptom relief in these patients. In patients with healed oesophagitis. 12-month maintenance therapy with lansoprazole 15 or 30 mg/day prevented recurrence and was similar to or more effective than omeprazole 10 or 20 mg/day. Available data in patients with NSAID-related disorders or acid-related dyspepsia suggest that lansoprazole is effective in these patients in terms of the prevention of NSAID-related gastrointestinal complications, ulcer healing and symptom relief. Meta-analytic data and postmarketing surveillance in >30,000 patients indicate that lansoprazole is well tolerated both as monotherapy and in combination with antimicrobial agents. After lansoprazole monotherapy commonly reported adverse events included dose-dependent diarrhoea, nausea/vomiting, headache and abdominal pain. After short-term treatment in patients with peptic ulcer, GORD, dyspepsia and gastritis the incidence of adverse events associated with lansoprazole was generally < or = 5%. Similar adverse events were seen in long-term trials, although the incidence was generally higher (< or = 10%). When lansoprazole was administered in combination with amoxicillin, clarithromycin or metronidazole adverse events included diarrhoea, headache and taste disturbance. In conclusion, lansoprazole-based triple therapy is an effective treatment option for the eradication of H. pylori infection in patients with peptic ulcer disease. Preliminary data suggest it may have an important role in the management of this infection in children and the elderly. In the short-term management of GORD, lansoprazole monotherapy offers a more effective alternative to histamine H2-receptor antagonists and initial data indicate that it is an effective short-term treatment option in children and adolescents. In adults lansoprazole maintenance therapy is also an established treatment option for the long-term management of this chronic disease. Lansoprazole has a role in the treatment and prevention of NSAID-related ulcers and the treatment of acid-related dyspepsia; however, further studies are needed to confirm its place in these indications. Lansoprazole has emerged as a useful and well tolerated treatment option in the management of acid-related disorders.

The Brazilian Consensus on Gastroesophageal Reflux Disease considers gastroesophageal reflux disease to be a chronic disorder related to the retrograde flow of gastroduodenal contents into the esophagus and/or adjacent organs, resulting in a variable spectrum of symptoms, with or without tissue damage. Considering the limitations of classifications currently in use, a new classification is proposed that combines three criteria-clinical, endoscopic, and pH-metric-providing a comprehensive and more complete characterization of the disease. The diagnosis begins with the presence of heartburn, acid regurgitation, and alarm manifestations (dysphagia, odynophagia, weight loss, GI bleeding, nausea and/or vomiting, and family history of cancer). Also, atypical esophageal, pulmonary, otorhinolaryngological, and oral symptoms may occur. Endoscopy is the first approach, particularly in patients over 40 yr of age and in those with alarm symptoms. Other exams are considered in particular cases, such as contrast radiological examination, scyntigraphy, manometry, and prolonged pH measurement. The clinical treatment encompasses behavioral modifications in lifestyle and pharmacological measures. Proton pump inhibitors in manufacturers' recommended doses are indicated, with doubling of the dose in more severe cases of esophagitis. The minimum time of administration is 6 wk. Patients who do not respond to medical treatment, including those with atypical manifestations, should be considered for surgical treatment. Of the complications of gastroesophageal reflux disease, Barrett's esophagus presents a potential development of adenocarcinoma; biopsies should be performed, independent of Barrett's esophagus extent or location. In this regard the designation "short Barrett's" is not important in terms of management and prognosis.

Combination of bronchial asthma (BA) with Bauhin's valve failure (BVF) is characterized by exogenic form of BA, extrapulmonary allergy, digestion problems. Examination of 36 such patients using endoscopy, manometry and tube duodenography has shown frequent chronic disorder of duodenal patency and gastroesophageal reflux, dysbacteriosis of the large and small intestines. High concentration of middle mass molecular peptides reflects endogenic intoxication associated with abnormal composition of intestinal microflora. The above alterations give grounds to consider BVF as a factor of BA pathogenesis.

Gastroesophageal reflux disease is a common chronic disease in the older population. Because of the cumulative effects of acid reflux and delayed gastric emptying, the older adult is at risk for such complications as peptic strictures, esophagitis, and Barrett's esophagus. Providing information on the current care modes (lifestyle, dietary, pharmacologic, and surgical interventions) will help identify relevant solutions and help the older adult generate alternative safe and effective solutions to manage the disease. Many people struggle to change their lives and may need assistance to break old habits.

Gastro-oesophageal reflux disease (GORD) is a common, chronic disorder that can progress to erosive or ulcerative oesophagitis and other complications. Uncomplicated GORD can be defined using criteria that combine symptom assessment and the impact of symptoms on well being or quality of life. The extent of impairment of health-related quality of life (HRQL) in GORD patients has been evaluated using generic HRQL questionnaires, GORD-specific quality of life questionnaires or a combination of the two types of instruments. The impact of GORD on HRQL in affected individuals is proportional to the frequency and severity of heartburn, and is greater than that associated with many other chronic diseases. In the treatment of GORD, the goal should be complete symptom resolution as this has been shown to be associated with a clinically significant improvement in HRQL. Both drug treatment and surgical intervention have been successful in improving HRQL of patients with GORD when complete symptom resolution can be attained.

Gastro-oesophageal reflux disease (GORD) is a chronic disorder characterised by an increased exposure of the oesophagus to intragastric contents. Currently, GORD symptoms are maintained under control with antisecretory agents, mainly gastric proton pump inhibitors (PPIs). Although impaired oesophageal motility may partly underlie the pathophysiology of GORD, the use of prokinetic agents has been found to be unsatisfactory. To date, novel pharmacological approaches for GORD are mainly related to the control of transient lower oesophageal sphincter (LOS) relaxations (TLOSRs). The majority of patients with GORD have reflux episodes during TLOSRs, which are evoked by gastric distension, mainly occurring after ingestion of a meal. Patients with reflux disease with normal peristalsis and without or with mild erosive disease could potentially benefit from anti-TLOSR therapy. This therapy might also be of value to treat some severe forms of esophagitis in combination with PPIs. GABA-B-receptor agonists are the most promising class of agents identified so far for TLOSR control. The GABA-B-receptor agonist, baclofen, is the most effective compound in inhibiting TLOSRs in humans. Since baclofen has several CNS adverse effects, novel orally available GABA-B agonists are needed for effective and well tolerated treatment of GORD. Endogenous or exogenous cholecystokinin (CCK) causes a reduction in LOS pressure, an increase in TLOSR frequency and a reduction in gastric emptying. In healthy volunteers and patients with GORD, loxiglumide, a selective CCK1-receptor antagonist, was found to reduce the rate of TLOSRs, although its effect on postprandial acid reflux may be modest. Orally effective CCK antagonists are not marketed to date. The anticholinergic agent atropine, given to healthy volunteers and patients with GORD, markedly reduced the rate of TLOSRs. Because of severe gastrointestinal (and other) adverse effects of anticholinergics, including worsening of supine acid clearance and constipation, it is unlikely that this class of drugs will have a future as anti-TLOSR agents on a routine basis. In spite of their effectiveness in reducing TLOSR rate, untoward adverse effects, such as addiction and severe constipation, currently limit the use of morphine and other opioid mu-receptor agonists. The same applies to nitric oxide synthase inhibitors, which are associated with marked gastrointestinal, cardiovascular, urinary and respiratory adverse effects. Animal studies provide promising evidence for the use of cannabinoid receptor 1 agonists, by showing potent inhibition of TLOSRs in the dog, thus opening a new route for clinical investigation in humans. A better understanding of TLOSR pathophysiology is a necessary step for the further development of novel drugs effective for anti-reflux therapy.
