Upper gastrointestinal diseases in the elderly: report of a meeting held at Vicenza, Italy, on 20 March 1998.

The aim of this article is to summarize the recent progress in geriatric/gastroenterological topics, particularly of the upper gastrointestinal tract, which were the focus of the First International Meeting on Upper Gastrointestinal Diseases in the Elderly, held in Vicenza, Italy, in March 1998. The Meeting was divided into three sections: gastro-oesophageal reflux disease (GORD) in the elderly, Helicobacter pylori infection in the elderly, and nonsteroidal anti-inflammatory drugs (NSAIDs) and the upper gastrointestinal tract in the elderly. GORD presents unique clinical features in elderly patients. The changes in oesophageal function, particularly disorders of motility, only partially explain its unique clinical manifestation. The diagnostic, clinical and therapeutic characteristics of GORD in the elderly need to be studied with attention to avoid its severe local complications, i.e. bleeding, stenosis and Barrett's oesophagus, as well as the more generalized risks of disability, impairment of nutritional status and reduction in the quality of life. Epidemiological studies have demonstrated that the prevalence of H. pylori infection increases with ageing and that subjects living in nursing homes have discrete epidemiological characteristics which render them a high-risk group. The incidence of some histological modifications of the gastric mucosa, particularly intestinal metaplasia, gastric atrophy and gastric cancer, seems to be both age- and H. pylori-related; their study in elderly subjects could give the key to understanding the pathophysiological mechanisms of H. pylori gastric damage. NSAID-related gastroduodenal damage, particularly haemorrhage, increases with age. Ageing, per se, does not modify significantly gastric aggressive factors, such as acid and pepsin secretions; however, a selective and specific reduction in some gastric defensive mechanisms seems to occur with ageing. Clinical studies on prevention of NSAID damage have rarely been performed in an elderly population, and meta-analyses of published data can lead to conflicting conclusions from a pharmaco-economic perspective. The identification of risk factors of NSAID-related gastroduodenal damage must be the foundation of preventive medical care for elderly subjects.
