Omeprazole is more effective than cimetidine in the prevention of recurrence of GERD-associated heartburn and the occurrence of underlying oesophagitis.

BACKGROUND: There is documentation of the long-term use of omeprazole 10 mg o.d. in patients with reflux oesophagitis but not in the large number of gastrooesophageal reflux disease (GERD) patients without oesophagitis. There is also a paucity of data on the long-term use of cimetidine in GERD patients. METHODS: One hundred and fifty-six patients (100 male) who previously had symptomatic non-ulcerative oesophagitis (81%) or symptoms without oesophagitis (19%), were recruited. All patients were in symptomatic remission following 4 weeks of omeprazole 20 mg o.d. or cimetidine 400 mg q.d.s. and, if required, a further 4 weeks of omeprazole 20 mg o.d. Patients were randomized to receive, double-blind, either omeprazole 10 mg o.m. (n = 77) or cimetidine 800 mg nocte (n = 79) for 24 weeks. RESULTS: A greater proportion of patients receiving omeprazole, compared with cimetidine, were in symptomatic remission after 12 (69 vs. 27%) and 24 weeks (60 vs. 24%) (each P < 0.0001). The median time to symptomatic relapse was longer for patients receiving omeprazole (169 vs. 15 days) (P = 0.0001). Of patients leaving the study in symptomatic remission, a greater proportion receiving omeprazole, compared with cimetidine, was free of oesophagitis (84 vs. 53%) (P < 0.05). CONCLUSION: Omeprazole 10 mg o.m. is more effective than cimetidine 800 mg nocte in the prevention of recurrence of GERD-associated heartburn and the occurrence of underlying oesophagitis.

Gastroesophageal reflux. Don't forget to ask about heartburn.

At least 13% of the US adult population have chronic heartburn, and unknown percentages of others have related symptoms of gastroesophageal reflux disease. Studies show that most people with symptoms of reflux self-medicate and do not seek medical advice. Also, they fail to mention these symptoms when visiting their physician for other conditions. Therefore, the importance of thorough history taking cannot be overstated, and it may be prudent for primary care physicians to question all patients routinely about reflux symptoms.

A study of the nonprescription drug consumer's understanding of the ranitidine product label and actual product usage patterns in the treatment of episodic heartburn.

INTRODUCTION: A study of the consumer's understanding of the product label instructions and the resulting product use were conducted to support the switch of a product from prescription to nonprescription status. H2 receptor antagonists have recently been approved for nonprescription use. This study evaluated the consumer's understanding of the product label for ranitidine hydrochloride (Zantac 75) and the product usage pattern in the treatment of episodic heartburn. OBJECTIVES: Our objectives were to evaluate each aspect of the communication of labeled indications, contraindications, and directions for use of two label formats (old and new) for a new nonprescription preparation of ranitidine (Zantac) and to evaluate nonprescription consumers' use of ranitidine 75-mg tablets (as Zantac 75) in a medically unsupervised, at-home setting to observe whether these consumers used the product appropriately and followed directions as written on the package label. METHODS: Adult male and female consumers (n = 1405) in a shopping mall environment who were attracted to a poster asking, "Do you have stomach problems?" were recruited for the label comprehension phase (two different label formats) and the 3-week usage phase if after reading the Zantac 75 package label they decided the product was appropriate for them. No instructions regarding the use of Zantac 75 were provided beyond what was printed on the package label. Subjects recorded use in a diary and tablet counts were performed at the end of the study period. A medical history was also taken at this time and an assessment of product use was performed by a physician. RESULTS: In at least 84% of all subjects, both formats were effective in the communication of label objectives for the contraindication against concurrent prescription stomach ulcer medication, maximum daily dose, and maximum duration of dosing at maximum daily doses. The direction to take one tablet per dose was adhered to by 90% of consumers, and 90% of consumers followed the instructions to take no more than two tablets in 24 hours. Ninety-six percent of consumers complied with the direction not to take the maximum daily dose for more than 14 consecutive days. Notably, the maximum daily dose was taken for < or =3 consecutive days by 79% of consumers. The most frequently reported adverse events were headache, acute nasopharyngitis, upper respiratory tract infection, diarrhea, nausea, and menstrual cramps. CONCLUSION: The study demonstrated that the vast majority of a large sample of unsupervised consumers understood the package label and fully complied with the package directions by not exceeding the maximum daily dosage and length of use. Nonprescription consumers safely used Zantac 75 without medical supervision.

A single dose of ranitidine 150 mg modulates oesophageal acid sensitivity in patients with functional heartburn.

BACKGROUND: The rapid onset and symptomatic response to histamine-2 receptor antagonists prior to the pharmacological effect on acid secretion suggests a different mechanism of action. AIM: To determine if ranitidine decreases oesophageal sensitivity to chemical and mechanical stimulation, potentially via oesophageal histamine receptors. METHODS: A total of 18 patients with functional heartburn received oral ranitidine 150 mg b.d. or placebo for 7 consecutive days in a double-blind randomized crossover design and underwent Barostat balloon distention and Bernstein acid infusion on study day 1 (90 min postdose) and study day 7. First sensation and pain were recorded and pain severity was rated on a 5-point Likert scale and a 100 mm visual analogue scale. Least square mean values were generated and one-tailed t-tests were performed. RESULTS: After a single dose of ranitidine 150 mg, time to pain with oesophageal acid infusion was increased by 29% (P < 0.05) and visual analogue scale and Likert scores were decreased by 20% (P < 0.06) and 23% (P < 0.02), respectively compared with placebo. After 1 week of ranitidine, positive alterations in sensory parameters persisted. Balloon distention sensory parameters were not altered by ranitidine. CONCLUSIONS: Ranitidine significantly decreased oesophageal sensitivity to acid. Failure of ranitidine to improve balloon sensory parameters supports existence of multiple sensory pathways in the oesophagus.

Review article: the management of heartburn in pregnancy.

Heartburn is a normal consequence of pregnancy. The predominant aetiology is a decrease in lower oesophageal sphincter pressure caused by female sex hormones, especially progesterone. Serious reflux complications during pregnancy are rare; hence upper endoscopy and other diagnostic tests are infrequently needed. Gastro-oesophageal reflux disease during pregnancy should be managed with a step-up algorithm beginning with lifestyle modifications and dietary changes. Antacids or sucralfate are considered the first-line drug therapy. If symptoms persist, any of the histamine2-receptor antagonists can be used. Proton pump inhibitors are reserved for women with intractable symptoms or complicated reflux disease. All but omeprazole are FDA category B drugs during pregnancy. Most drugs are excreted in breast milk. Of systemic agents, only the histamine2-receptor antagonists, with the exception of nizatidine, are safe to use during lactation.

Metoclopramide and the gastro-oesophageal sphincter. A study in pregnant women with heartburn.

In a double-blind study the gastro-oesophageal sphincter pressure profile was measured in a group of twenty women in the last trimester of pregnancy, all of whom suffered from heartburn. The mean gastric and the maximum sphincter pressures were calculated from the pressure profile, and the difference between these two was defined as the barrier pressure. After resting sphincter measurement ten of the women were given 10 mg metocolopramide intravenously, and the other ten had a placebo intravenous injection; 15 min later the sphincter pressures were measured again. Metoclopramide significantly increased the mean maximum sphincter and barrier pressures compared to the baseline pressure, and there was no significant difference between the pre- and post-injection pressures in the placebo group. However, the raised mean maximum sphincter and barrier pressures following metoclopramide were made up of four patients having very high pressures and six patients on whom metoclopramine appeared to have little effect. The clinical usefulness of metoclopramide in women in labour is discussed.

Characterization of cortical potentials evoked by oesophageal balloon distention and acid perfusion in patients with functional heartburn.

Oesophageal visceral hypersensitivity is thought to be important in generating symptoms in functional heartburn (FH). However, the neurophysiological mechanisms involved are poorly understood. The aim of this study was to compare the characteristics of oesophageal cortical evoked potentials (CEPs) induced by balloon distension and acid perfusion in FH and controls. We studied 21 FH patients and 12 healthy volunteers. Oesophageal mechanical stimulation was performed using the specially constructed mechanical pump. CEPs were recorded using the 10-20 international system of electroencephalogram recording. Oesophageal distention elicited recognizable, reproducible and muti-peak CEPs. CEP latencies for N1, P1 and N2 components were significantly shorter (P = 0.016, P = 0.003 and P = 0.031, respectively) in FH than in controls before perfusion. Acid perfusion significantly decreased the latencies of N1, P1 and N2 (P = 0.022, P = 0.007 and P = 0.041, respectively) and significantly increased the amplitude of P1-N2 components (P = 0.020) in FH patients, but not in controls. In conclusion, cortical evoked potential responses evoked by oesophageal distention and acid perfusion were greater in FH than in controls, suggesting that dysfunction of visceral neural pathways and/or alterations in cortical processing may produce and mediate oesophageal hypersensitivity in FH. These findings provide the evidence that central sensitization contributes to the development and maintenance of oesophageal hypersensitivity.

Heartburn and multiple-site foregut perforations as primary manifestation of Crohn's disease.

SUMMARY: Crohn's disease may affect any segment of the digestive tract, more commonly the distal ileum, colon and/or perianal region. There is an increasing number of reports dealing with foregut Crohn's disease. We present the case of a patient with a history of heartburn and multiple spontaneous perforations of the esophagus, duodenum and jejunum as a primary manifestation of Crohn's disease who required emergency surgical and endoscopic procedures. Early detection of Crohn's disease may decrease the incidence of acute life-threatening complications provided that appropriate medical treatment is administered and a multidisciplinary approach is offered to these patients.

Hiatus hernia and heartburn.

The symptoms in a group of 80 patients with a pure sliding hiatus hernia were investigated using the pyloric regulation test (Capper, Airth, and Kilby, 1966). It was found that there was a high correlation between the symptoms of heartburn and the reflux of duodenal barium into the stomach.

Heartburn--the acid test.

To determine whether symptoms of gastro-oesophageal reflux are related to the degree of oesophageal acid exposure, 190 patients (of 220 referred) with heartburn and acid regurgitation were compared with 50 normal subjects. A definite relationship between frequency of reflux symptoms and degree of oesophageal acid exposure was found both in patients with and without oesophagitis. We conclude that the frequency of gastro-oesophageal reflux symptoms is related to degree of oesophageal acid exposure.

Oesophageal motility during acid-provoked heartburn and chest pain.

Oesophageal motility was studied in 59 patients before and again after prolonged acid perfusion. In group 1 (n = 16), who were asymptomatic during the acid perfusion, no significant motility differences were obtained by perfusion. In group 2 (n = 18), who had heartburn, and in group 3 (n = 25), who had angina-like chest pain during acid perfusion, significant (p less than 0.01-0.001) changes of motility were seen: these included higher peristaltic amplitude, longer contraction duration, and slower peristaltic velocity. In addition, patients in group 3 showed a decrease (p less than 0.01) of peristaltic propagation and had secondary wave activity more often (p less than 0.01) during acid perfusion. Significantly (p less than 0.01) more patients in group 3 showed secondary wave activity after acid perfusion than in group 2. Pretest motility investigation did not separate the two acid-sensitive groups from the acid-unsensitive one, whereas the investigation of the lower oesophageal sphincter (LOS) did. Thus, LOS incompetence was significantly (p less than 0.01) commoner in the two symptomatic groups than in the asymptomatic group. We suggest that the motility changes observed during acid perfusion are secondary to increased sensory stimulation from the oesophagus but are not the cause of the symptoms. However, nervous reflex reactions from other chest organs, such as the heart, may also explain the results.

A practical approach to heartburn.

Heartburn and other symptoms of gastroesophageal reflux disease can be a lifelong problem, affecting millions of Americans each year. Fortunately, treatment has improved dramatically over the past decade. Medications currently available are remarkably safe and, with proper selection, almost universally effective. When indicated, surgical treatment is also highly effective.

Gastroesophageal reflux disease: gaining control over heartburn.

GERD is a common disorder. Symptoms of reflux, such as heartburn, are due to a combination of factors: relaxation of the lower esophageal sphincter, hypersecretion of gastric acid, and resulting burning of the esophageal mucosa. Symptoms are usually classified as classic, atypical, or complicated. Treatment approaches include dietary and lifestyle changes, reduction of acidity with use of H2 receptor antagonists, and reduction of acid secretion with use of proton pump inhibitors. Patient motivation is an important factor in the management of gastroesophageal reflux. In rare instances, patients do not respond to medical treatment and are candidates for antireflux surgery.

Heartburn of pregnancy.

Lower esophageal sphincter pressure, basal gastric pH, fasting plasma gastrin, and plasma concentrations of estrone, estradiol, and progesterone were measured in pregnant volunteers at 12, 24, and 36 weeks of gestation, and again at 1 to 4 weeks postpartum. In addition, basal and pentagastrin-stimulated acid secretory responses at each time were measured. No differences in basal gastric pH, basal, and peak acid outputs were observed during pregnancy when compared to the postpartum values. In contrast, lower esophageal sphincter pressure was reduced at all times during pregnancy, reaching a nadir at 36 weeks. Postpartum lower esophageal pressures were normal. As expected, plasma concentrations of progesterone and both estrogens increased progressively during pregnancy. These data are consistent with earlier studies in women ingesting oral contraceptives. Moreover, they provide support for the thesis that the progressive increase in plasma progesterone alone or in combination with estrogens that occurs during pregnancy is responsible for the reduction of lower esophageal sphincter pressure which allows esophageal reflux to occur with the resultant development of symptomatic heartburn.

What do heartburn sufferers expect from proton pump inhibitors when prescribed for the first time?

AIM: Based on several consensus reports, the official goals of gastroesophageal reflux disease (GERD) treatment are symptom relief, healing of esophagitis, prevention of complications and also prevention of relapses. The aim of the present study was to evaluate the expectations of heartburn sufferers referred to primary endoscopic examination in a prescribed proton-pump-inhibitor (PPI) therapy, also in relation to the official treatment goals. METHODS: A group of 91 patients has been sent to the Division of Gastroenterology of the Public Hospital of Zell am See for a first endoscopic examination because of recurrent GERD-related symptoms. All patients (59 men, 32 females), mean age 44.8 years (range 28 to 63 years), treated their symptoms themselves using over-the-counter medication and/or life-style modification and diet. Subsequent to endoscopic examination and medical prescription all patients were asked about their expectations in a prescribed PPI therapy (open technique). RESULTS: Of the complete sample, only 4 patients (4.4%) had no real expectations in the prescribed antireflux medication. The leading expectations were: 1) an improvement in (61%) or elimination of (33%) perceived symptoms; 2) healing of esophagitis (50%); 3) in 46% of the patients a return to normal daily life and in 44% an improvement in quality of life respectively. Thirty-six percent expected no further therapy following this initial treatment and 34% no side-effects of PPI treatment. CONCLUSIONS: The leading patient-related expectations in PPI therapy are related to their perceived symptomatology, an improvement in quality of life, healing of esophagitis, and also a long-term efficacy of treatment. Most of these factors expected by the patients are in relation to the official treatment goals, but especially aspects such as quality of life and normal daily activities should be included as endpoints of treatment.

Rumination, heartburn, and daytime gastroesophageal reflux. A case study with mechanisms defined and successfully treated with biofeedback therapy.

A 31-year-old man with a 19-year history of rumination developed frequent episodes of heartburn and regurgitation associated with acid gastroesophageal reflux that occurred predominantly during the day. This reflux and its attendant symptoms resulted from abdominal muscle contractions at the time of gastroesophageal pressure equilibration (i.e., common cavity phenomena) consistent with the egress of air from the stomach to the esophagus. A voluntary pharyngeal maneuver unassociated with swallowing but simultaneous with the abdominal contraction resulted in a decrease in upper esophageal sphincter pressure. This lowered pressure facilitated acid esophagopharyngeal regurgitation at a velocity of 100 cm/s. Biofeedback therapy directed at relaxing the abdominal muscles during eating and avoiding the pharyngeal maneuver resulted in a decrease in reflux and marked improvement in symptoms.
