Medical therapy for supraesophageal complications of gastroesophageal reflux

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.

Outcome of laparoscopic Nissen-Rossetti fundoplication in children with gastroesophageal reflux disease and supraesophageal symptoms

BACKGROUND

The role of surgery is debated for children with gastroesophageal reflux disease (GERD), particularly when they show atypical symptoms. This study was designed to evaluate the safety and outcome of laparoscopic Nissen-Rossetti fundoplication performed in a selected population of children with gastroesophageal reflux and atypical supraesophageal symptoms.

METHODS

This prospective study included 595 patients younger than 14 years with GERD who reported recurrent respiratory symptoms and had no benefit from standard medical treatment. Surgery was performed for 48 patients with anatomic anomalies, life-threatening events, or respiratory complications after ineffective medical treatment. The subjective and objective outcomes were evaluated.

RESULTS

No major intraoperative complications were experienced, and there was no recurrence of gastroesophageal reflux during a postoperative follow-up period of 12 months. The parents' final subjective evaluation of the outcomes 12 months after surgery was positive in 44 cases and negative in 4 cases.

CONCLUSIONS

Children with difficult-to-treat chronic respiratory symptoms must be evaluated for GERD, even if the need for surgery is low (8%), because complete eradication of reflux is mandatory. Radical treatment of GERD allows the pulmonologist to perform correct respiratory treatment and to prevent the development chronic and life-threatening complications.

Supra-oesophageal manifestations of gastro-oesophageal reflux disease

Since the early 1960s, many studies have been published that consider the possible relationship between gastro-oesophageal (acid) reflux (GORD) and various other complaints, including dental erosions, ear, nose and throat problems, chronic cough and asthma. Although a high coincidence of GORD and these supra-oesophageal complaints have been noted, there is no consensus on the pathophysiology and management of such complications. In this article we review the literature published between 1966 and 2000 on this subject. We also analyse the available information on the incidence, pathophysiological mechanisms, diagnostic approach and therapeutic options in the various subgroups of disorders.

The role of gastroesophageal reflux in the pathogenesis of laryngeal carcinoma

Gastroesophageal reflux (GER) has been strongly associated with carcinogenesis of the lower esophagus and development of several otolaryngologic disorders. Epidemiologic studies support concept that the malignant transformation of laryngeal mucosal surfaces is due to GER-initiated chronic laryngeal inflammation. However, large clinical studies with matched control groups and further experimental investigations are necessary to ascertain the relationship between reflux and laryngeal carcinoma. This review stresses that early diagnosis of GER disease, based on clinical suspicion, ambulatory 24-hour double-probe pH monitoring, and endoscopic examination, as well as effective treatment of reflux, are considered the keys for relief of symptomatology and preventing the chronic irritation of the laryngeal mucosa that may contribute to the development of laryngeal carcinoma.

Extraesophageal gastroesophageal reflux disease. Presentations and approach to treatment

Prevalence of gastroesophageal reflux disease (GERD) is common in the adult US population, but likely is underestimated as many patients present with symptoms other than heartburn or regurgitation. Ears, nose, throat, pulmonary, and cardiac symptoms also frequently are related to GERD. The diagnosis of GERD as a cause of these symptoms can be difficult and treatment strategies are much less clear than in patients presenting with heartburn or regurgitation. This article discusses the epidemiology, pathogenesis, diagnosis, and treatment of some of the manifestations of extraesophageal reflux disease.

Recognizing atypical manifestations of GERD. Asthma, chest pain, and otolaryngologic disorders may be due to reflux

The presence of common symptoms, such as heartburn and regurgitation, usually make the diagnosis of gastroesophageal reflux disease (GERD) fairly straightforward. However, extraesophageal symptoms of GERD, such as asthma, noncardiac chest pain, and hoarseness, are often not recognized and therefore are poorly managed. This article sheds light on the atypical manifestations of GERD as well as current approaches to diagnosis and treatment.
