Of 333 duodenal ulcer (DU) patients 75 (22.5%) were aged 65-93 years (study group). Ninety-two percent (306 patients) of the entire group were diagnosed endoscopically, and all were followed prospectively. In the study group of the older patients there were fewer smokers, but more patients used steroids and other nonsteroidal antiinflammatory drugs (NSAIDs) and had more arteriosclerotic heart disease than the younger control group. Presenting signs and symptoms were similar in both age groups, although painless upper gastrointestinal bleeding was more common in the elderly, and pain, when present, tended to be milder. Bleeding episodes were more prevalent in the older age group. Another difference between the groups was the larger incidence of concurrent gastric ulcer and DU observed endoscopically in the study population. Steroids and NSAIDs could be etiologically connected to bleeding in the older patients, as well as to their relative lack of pain. We conclude that DU in the elderly tended to present atypically and that pain was not the major symptom of activity. This places a different emphasis on diagnostic and therapeutic criteria.

A 42-year-old man had a 4 year history of sarcoidosis stage II (lung). In biopsied specimens of the antrum we found epithelioid granulomas caused by gastric involvement in sarcoidosis. Coincidentally we found a gastric ulcer which was later the source of gastric bleeding. The granulomas were located around this ulcer and also under intact mucosa. Therefore, in our opinion it was not the case that granulomatous gastritis caused the ulceration in a direct way. We saw a connection between hypercalcemia--often found in patients with sarcoidosis, as in our patient--and the gastric ulcer. Therapy was thus aimed at lowering the blood calcium concentration. Steroids were avoided at this time. The ulceration healed, although granulomatous gastritis continued.

Nearly half a century ago Revers reported that administration of a paste prepared from succus liquiritiae, a dried watery extract of the roots of Glycyrrhiza glabra, resulted in a reduction in abdominal symptoms as well as radiographic evidence of healing in patients suffering from gastric ulcer. Subsequent studies demonstrated that this preparation could prevent the formation of gastric ulcers in experimental animals and confirmed the salutary effects in patients, but found that approximately 20% of patients so treated developed facial and dependent edema, often accompanied by headache, shortness of breath, stiffness, and pain in the upper abdomen. Although these symptoms suggested an allergic reaction, they were not accompanied by eosinophilia or relieved by antihistamines. These untoward effects usually subsided with a reduction of dose, although in some patients treatment had to be discontinued entirely. Given this profile of side effects, enthusiasm for licorice as a remedy for peptic ulcer disease soon faded. However, the popularity of licorice flavoring in candy and in other products such as chewing tobacco persists to this day, as do the problems in electrolyte and blood pressure homeostasis that can occasionally occur in individuals ingesting large quantities of licorice-containing products. Although the pattern of the renal response suggested that the active ingredients in licorice were acting directly on the mineralocorticoid receptors in the kidney, an even more fascinating explanation for the toxic effects of licorice has emerged in the past decade.(ABSTRACT TRUNCATED AT 250 WORDS)

Agave plants are popular for their myriad applications in traditional medicine attributed to their reported anti-inflammatory, immunomodulatory, cytotoxic and antifungal activities. The aim of this study was to examine the anti-inflammatory, immunomodulatory and ulceroprotective activity of Agave species in relation to their metabolite fingerprint via a metabolome based ultra-performance liquid chromatography-mass spectrometry (UPLC-MS) approach coupled to chemometrics. The metabolomic differences among five examined Agave leaves viz. Agave americana L., A. americana var. marginata Trel, A. angustifolia Haw. cv. marginata, A. desmettiana Jacobi, A. pygmaea Gentry were determined via a total of 56 annotated metabolites. Identification based on MSn and UV spectra revealed 25 steroidal saponins and sapogenins, 6 flavonoids, 2 homoisoflavonoids, 7 phenolic acids, 6 fatty acids and 3 fatty acid amides, some of which are reported for the first time in Agave. Metabolites heterogeneity was assessed among leaf taxa via multivariate data analyses for samples classification, showing that saponins is the major metabolite contributing to their classification. The carrageenan induced acute inflammatory rat model was used to assess the anti-inflammatory activity of Agave extracts via monitoring of blood cytokine levels. Additionally, their effects on ethanol-induced gastric ulcer in rats were evaluated. A. pygmaea showed the most significant anti-inflammatory and immunomodulatory activity, while A. angustifolia var. marginata possessed the highest ulceroprotective activity, which could be attributable to the high abundance of various saponins and homoisoflavonoids in those taxa.
