Functional Gastroesophageal Reflux Disease (GERD)

Eosinophilic Esophagitis in Children and Adolescents with Abdominal Pain: Comparison with EoE-Dysphagia and Functional Abdominal Pain

Aim. Compare EoE-AP with EoE-D for clinical, endoscopy (EGD), histology and outcomes and also with FAP-N. Method. Symptoms, physical findings, EGD, histology, symptom scores, and treatments were recorded for the three groups. Cluster analysis was done. Results. Dysphagia and abdominal pain were different in numbers but not statistically significant between EoE-AP and EoE-D. EGD, linear furrows, white exudates were more in the EoE-D and both combined were significant (p < 0.05). EoE-D, peak and mean eosinophils (p  0.06) and eosinophilic micro abscesses (p  0.001) were higher. Follow-Up. Based on single symptom, EoE-AP had 30% (p  0.25) improvement, EoE-D 86% (p < 0.001) and similar with composite score (p  0.57 and <0.001, resp.). Patients who had follow-up, EGD: 42.8% with EoE-AP and 77.8% with EoE-D, showed single symptom improvement and the eosinophil count fell from 38.5/34.6 (peak and mean) to 31.2/30.4 (p  0.70) and from 43.6/40.8 to 25.2/22.8 (p < 0.001), respectively. FAP-N patients had similar symptom improvement like EoE-D. Cluster Analysis. EoE-AP and FAP-N were similar in clinical features and response to treatment, but EoE-D was distinctly different from EoE-AP and FAP-N. Conclusion. Our study demonstrates that EoE-AP and EoE-D have different histology and outcomes. In addition, EoE-AP has clinical features similar to the FAP-N group.

Night-time gastro-oesophageal reflux disease: prevalence, hazards, and management

Patients who complain of symptoms of gastro-oesophageal reflux disease (GORD) that occur at night require special attention. Night-time GORD can profoundly impair quality of life by causing pain, disturbing sleep, and interfering with next-day mental and physical functioning. Sleep impairs oesophageal acid clearance resulting in a prolongation of acid mucosal contact, and nocturnal reflux portends a greater risk of erosive oesophagitis and other significant complications of gastro-oesophageal reflux. Lifestyle changes such as elevating the head of the bed and adjusting the sleeping position can relieve night-time heartburn, and instituting some dietary changes along with occasional use of histamine H2 blockers can also be helpful. Relief of night-time reflux and its attendant symptoms usually requires a medication with acid-suppressing properties that extend into the sleeping interval. In most instances, more powerful acid suppression in the form of proton-pump inhibitors will be required. Clinical studies have shown that 40 mg esomeprazole provides better control of night-time GORD symptoms than 20 mg omeprazole or 30 mg lansoprazole. Furthermore, 40 mg pantoprazole offers even faster relief than 40 mg esomeprazole for night-time GORD symptoms. Of the several proton-pump inhibitors available on the market, esomeprazole and pantoprazole appear to have some advantages, which have been documented in recent studies. Esomeprazole has been shown to be more effective than lansoprazole in relieving GORD symptoms, and esomeprazole and pantoprazole appear to be equally effective in resolving GORD symptoms in a comparative study. Pantoprazole has pharmacokinetic properties that document a longer half-life compared with the other proton-pump inhibitors, and pantoprazole has the slowest inhibition recovery rate. These properties lend credence to pantoprazole as an effective treatment for associated symptoms of night-time reflux.

Improvement of reflux symptoms 3 years after cure of Helicobacter pylori infection: a case-controlled study in the Japanese population

BACKGROUND

Development of reflux esophagitis is one of the adverse effects that cause concern in relation to curative treatment of Helicobacter pylori infection. However, recent studies present a rather negative association between curative treatment and development of reflux esophagitis or reflux symptoms. Therefore, this issue has remained controversial. Accordingly, we investigated the long-term adverse effects of H. pylori eradication treatment in special reference to development of reflux symptoms.

PATIENTS AND METHODS

We conducted a case controlled study by mailing structured questionnaires on past (before curative treatment or 3 years previously) and current status. A case was an endoscopically confirmed peptic ulcer patient with confirmed cure of the infection after eradication treatment 3 years previously and a control was one who had not undergone the eradication treatment during the same period. We studied 241 pairs who matched for age, gender, and type of ulcer disease (GU, DU or GDU). Of these pairs, 81.3% were male and the mean age was 52.6 +/- 9.6 year (range 23-76).

RESULTS

The rates of patients with improved reflux symptoms in the case and control groups were 65.4% and 30.4%, respectively, with the rate being significantly greater in the case group. On the contrary, the rates of those with worsened reflux symptoms were similar (5.1% and 7.6%). Regarding general events, the rate of patients with decreased frequency of hospital visits and of those who regularly used antiacid medications were significantly decreased in the case group. Furthermore, the case group experienced significantly fewer hospital admissions for various diseases in this 3-year period. However, a significantly greater number of case group patients than control subjects gained weight.

CONCLUSION

Reflux symptoms as well as general well-being were significantly improved after cure of H. pylori infection.
