Herpes simplex virus types 1 and 2 and cytomegalovirus in peptic ulcer disease and non-ulcer dyspepsia.

The prevalence and the serum levels of IgG antibody to Herpes simplex virus type 1 or 2 (HSV1, HSV2) and to cytomegalovirus (CMV) were studied by ELISA in patients with active peptic ulcer -- duodenal and gastric -- and non-ulcer dyspepsia. Two hundred and forty-two consecutive patients with endoscopically confirmed active peptide ulcer -- 170 duodenal ulcers, 72 gastric ulcers -- and 95 consecutive patients who fulfilled the criteria for the diagnosis of non-ulcer dyspepsia were included in the study. The patients, aged 17-80 years, were well matched for age and sex. Antibody to cytomegalovirus was found in 83% of duodenal ulcer, 85% of gastric ulcer and 75% of non-ulcer dyspepsia patients; differences were not significant. The prevalence of HSV1 antibody was significantly higher in patients with duodenal ulcer than in those with non-ulcer dyspepsia (p < 0.025); the prevalence of HSV2 antibody was significantly higher in patients with duodenal or gastric ulcer, than in those with non-ulcer dyspepsia (p < 0.05, p < 0.01, respectively); however, antibody levels (mean optical density) to the viruses studied were similar for all groups of patients. These results provide some evidence that HSV might be implicated in the pathogenesis of peptic ulcer disease.

[Comparative pathologic study on the peri-ulcer mucosal lesion around benign and malignant gastric ulcer].

3441 peri-ulcerous mucosal lesions around benign and malignant gastric ulcers (1479 benign gastric ulcers, 421 cancerous degeneration of benign ulcers and 1541 ulcerative carcinomas) were studied comparatively. It was found that the ulcer of cancerous degeneration of benign ulcer was small and the epithelial regeneration at the ulcer's edge and fusion of the muscularis mucosa with the muscularis propria were very common. The cancerous tissue, extending down to the submucosa, was found at the margin but not at the base of the ulcer. Lymph node metastasis was rare. Therefore, the cancerous degeneration of ulcer was most likely an early carcinoma. These findings conform well with Hauser's criteria. Chronic atrophic gastritis intestinal metaplasia (IIb and type II), moderate and severe dysplasia were more commonly observed in cancerous degeneration of ulcers than in benign peptic ulcers or ulcerative carcinoma. These results suggest that multiple biopsies should be taken from the edge of chronic ulcers.

[Endoscopic studies on refractory gastric ulcers, especially, linear ulcers, treated with proton pump inhibitor].

Seven patients with refractory gastric ulcers against H2-blocker therapy, were treated with omeprazole, and the endoscopic findings serially followed. Round ulcers improved steadily with treatment in two cases. However, healing of the ulcers was not complete and very small pin-point ulcers remained. Therefore, a prostaglandin E1 analogue was added at the 14 and 16th week of omeprazole therapy. The ulcers healed completely, two weeks later. In five cases with linear ulcers, one case discontinued the taking of omeprazole. The linear ulcers in the other four cases healed completely within 4 to 11 weeks. Endoscopically, some parts of the linear ulcers were initially scarred and the ulcers were divided into several short ulcers. The ulcers separated there after and healed respectively. These findings suggest that the healing process of linear ulcers may represent the reversed course of the developing process of linear ulcers. The results indicate that omeprazole is highly effective for the treatment of refractory gastric ulcers.

[Ulcer location in the stomach and pylorantral hypertrophy: problem of correlation of the ulcer location and wall hypertrophy in ulcus ventriculi].

Relationship between gastric ulcer (n = 100) site and antropyloric wall hypertrophy was examined in a prospective study. Irrespective of ulcer multiplicity most ulcers were found to be located at the lesser curvature and at the posterior wall (p less than 0,001); men had significantly more ulcers at the posterior wall than females (p less than 0, 001). Single ulcers and those connected with pyloric stenosis were more distant to the pylorus than multiple ulcers (p less than 0,001). Ulcer location did not relate to hypertrophy of the pyloric channel wall. Observed differences between single and multiple ulcers were limited to wall parts only: the musculature of high located single ulcers was significantly less hypertrophied 2,5 cm orally of the pylorus (p less than 0,02) and that of high multiple ulcers was more hypertrophied at the pylorus (p less than 0,02) than in the other parts. These findings suggest that ulcer variations do not influence the diffuse antropyloric disease in gastric ulcer patients and suggest that the generalized antral changes are prior to gastric ulcer occurance.

Gastric ulcers with and without associated duodenal ulcer have different pathophysiology.

1. Maximal acid output after pentagastrin stimulation, and fasting and postprandial serum gastrin concentrations were determined in 25 normal subjects, 30 patients with corpus gastric ulcers, 10 patients with prepyloric ulcers and 30 patients with both duodenal and gastric ulcers. 2. Corpus ulcers and prepyloric ulcers formed one distinct group. Maximal acid output was abnormally low in the corpus ulcer patients and no different from normal in prepyloric ulcer patients, whereas fasting serum gastrin and postprandial integrated gastrin response was abnormally high in the former and no different from the normal in the latter. Furthermore, as in the normal subjects, a significant negative correlation between maximal acid output expressed in mmol h(-1) kg(-1) body weight and postprandial integrated gastrin response was observed in the corpus and prepyloric ulcer patients taken as a group. 3. In complete contrast patients with both duodenal and gastric ulcers, in whom postprandial integrated gastrin response was statistically highest amongst the three types of gastric ulcers, had a significantly positive correlation between maximal acid output and the integrated gastrin response. 4. These findings suggest the operation of different pathophysiological mechanisms in gastric ulcers with and without associated duodenal ulcers.

[Studies on predilection area of gastric ulcer viewed from healing process of experimental gastric ulcers (author's transl)].

Clinically, it is true that gastric ulcer is more common along the lesser curvature and less common along the greater curvature. To elucidate this difference in ulcerognesis, two experimental ulcers were prepared in dogs at the sites, one at the angular incisure and the other at the corresponding greater curvature after the method by Hatafuku & Thal. The fates of these ulcers studied endoscopically, macroscopically, histologically and with the use of microangiography. The results obtained are summarized as follows. 1) When two ulcers only were prepared, better healing was consistent for the greater curve ulcer. 2) Experimental ulcers with simultaneous ligation of gastric vessels resulted in poor healing of both ulcers, though the greater curve ulcer showed better healing than the lesser curve ulcer. 3) Endoscopically, dogs with vessel ligation showed antral congestion and edema. These findings, however, disappeared in 3 to 4 weeks. 4) Histamine injection accelerated the rate of early perforation and both experimental ulcers showed no tendency of healing. In conclusion, delayed healing was almost consistent for the lesser curve ulcer under various conditions. The cause for this may be explained by the increased motility with repeated ischemic condition at the lesser curvature.

[Effects of FRG-8813, a new-type histamine H2-receptor antagonist, on the healing of gastric and duodenal ulcer in rats and spontaneously ulcerative mice].

We examined the anti-ulcer effects of FRG-8813, a new-type histamine H2-receptor antagonist, in chronic ulcer models of rats and mice (W/WV). FRG-8813, given orally twice a day for 7 days, accelerated the healing of gastric or duodenal ulcer induced by acetic acid injection or application at the non-antisecretory doses (0.3 approximately 3 mg/kg). Administration of FRG-8813 to rats with ulcers increased the amounts of mucus in the gastric mucosa. These actions of FRG-8813 were more potent than those of famotidine or cimetidine. In W/WV mice, several ulcers spontaneously developed on gastric mucosa during the 8 weeks after the birth. The ulcers were aggravated by several unknown factors after the ulcer generation in W/WV mice. The aggravation of ulcers was inhibited by the 4-week administration of FRG-8813 with diet at the dose of 1 or 10 mg/kg/day, but was not inhibited by cimetidine at the dose of 100 mg/kg/day. From these results, we suggest that FRG-8813 is able to accelerate the healing of ulcers by antisecretory plus increasing actions on the integrity of the gastric mucosal defense mechanisms; therefore FRG-8813 is expected to be a useful drug for the treatment of gastric or duodenal ulcers in humans.

Anti-ulcer effects of 4'-(2-carboxyetyl) phenyl trans-4-aminomethyl cyclohexanecarboxylate hydrochloride (cetraxate) on various experimental gastric ulcers in rats.

Anti-ulcer effects of cetraxate, a new compound possessing anti-plasmin, anti-casein and anti-trypsin actions were investigated by using experimental gastric ulcer models in rats. Cetraxate, 300 mg/kg p.o. showed significant inhibitory effects of 65.3%, 70.0%, 30.2%, and 67.1% against aucte types of ulcers producing by aspirin, phenylbutazone, indomethacin, and pyloric ligature (Shay's ulcer), respectively. These effects were greater than those obtained by gefarnate and aluminum sucrose sulfate may be mainly attributed to the protecting action of this drug on gastric mucosa. Ctraxate further revealed remarkable inhibitory effects on chronic types of ulcers produced by acetic acid, clamping, and clamping-cortisone. In acetic acid ulcer in particular, cetraxate was found to have a dose-dependent inhibitory effect at doses over 50 mg/kg. Of test drugs including L-glutamine and methylmethionine sulfonium chloride, cetraxate showed the most remarkable inhibitory effect on beta-glucuronidase activity in ulcer tissue of these three types of ulcers. These findings suggest that cetraxate may prevent the connective tissue in the ulcer location from decomposition due to lysosomal enzymes such as beta-glucuronidase, thereby accelerating the recovery from ulcer.

Gastric acid secretion in patients with prepyloric ulcer and with combined gastric and duodenal ulcer.

The gastric acid secretion during stimulation with histamine given via a continuous intravenous infusion (i.e. during steady state conditions) was studied in 13 patients with prepyloric ulcers and in 21 patients with combined gastric and duodenal ulcers. The rate of volume secretion, the acidity and the acid output were analysed separately. The results were compared with earlier studies of patients with gastric ulcer and duodenal ulcer. Starting from the secretory pattern these four groups of ulcer were characterized. Gastric ulcers thus show hypoacidity. The pyloric ulcers do not differ from a normal material. The combined gastric and duodenal ulcers and the duodenal ulcers show hypersecretion, most pronounced in duodenal ulcers.

Monthly variation of hospital admission and mortality of peptic ulcer disease: a reappraisal of ulcer periodicity.

The occurrence of peptic ulcer is characterized by a seasonal variation, the meaning of which is poorly understood. The present study examined the periodicity of hospital admissions and mortality resulting from gastric and duodenal ulcer to determine its etiologic relevance. Ulcer periodicity was studied in the nationwide data sets of the Department of Veterans Affairs, the Health Care Financing Administration, and the Vital Statistics. Both ulcer types were characterized by similar patterns of periodicity. Hospital admissions peaked during the first 3 months of the year, followed by a marked decline during summer and a second smaller peak around October. This pattern occurred independently of age, sex, race, and place of residence. It also pertained to ulcers complicated by hemorrhage or perforation. Although total admissions peaked earlier during the year and showed a less consistent peak in October, there was a close resemblance between the periodicity of all diseases and that of peptic ulcer. Mortality was highest in January and lowest in July for all disease and ulcer diseases alike. The similarity between the periodicity of peptic ulcer and other diseases suggests that the major factors responsible for the cyclic behavior of gastric and duodenal ulcer are not particular to these diseases but affect other unrelated diseases alike.

Hospitalization

The prevention of peptic ulceration by highly selective vagotomy in a new peptic ulcer experimental model: the bile duct-ligated pig.

Bile duct ligation produced gross peptic ulceration of the pars esophagea of the stomach, with a 70% mortality rate from hemorrhage or perforation. The situation and histological appearance of the ulcers was identical to the peptic ulcers that occur spontaneously in pigs. Previous work has shown that these ulcers are associated with gastric hypersecretion. The technique of highly selective vagotomy was established in the pig and was shown to have no short-term adverse effects. In a group of 10 pigs, highly selective vagotomy virtually eliminated pars esophageal peptic ulceration and significantly prolonged survival after bile duct ligation. The bile duct-ligated pig experimental peptic ulcer model should be of value in studying peptic ulceration and methods of treatment. Further investigation is required to determine the cause of death in those animals in which peptic ulceration is prevented by treatment, such as highly selective vagotomy.

Pyloric-sphincter studies in peptic-ulcer patients: pylorus in peptic ulcer.

Pyloric pressure was assayed by a manometric procedure in the basal state and after intraduodenal infusion of HCl. 13 control subjects, 11 patients with benign gastric ulcer, 8 with duodenal ulcer, and 2 with coexistent gastric and duodenal ulcers were studied. Mean resting pyloric pressure in gastric-ulcer patients (5.17 +/- 0.71) mm Hg) was significantly lower than controls (9.40 +/- 0.85 mm Hg) and did not increase after HCl perfusion into the duodenum. Mean basal pyloric pressure in duodenal-ulcer patients (11.30 +/- 1.57 mm Hg) did not differ significantly from controls and increased after intraduodenal perfusion of HCl to 15.72 +/- 2.40 mm Hg. The two patients with coexistent ulcers had manometric patterns similar to gastric-ulcer patients. Decreased pyloric-sphincter pressure in gastric-ulcer patients may be the mechanism responsible for the increased duodeno-gastric reflux observed in these patients.

Complications associated with ulcer recurrence following gastric surgery for ulcer disease.

The present study is an attempt to assess the risks of the complications associated with recurrent ulcers in patients who have undergone gastric surgery and to determine whether these risks differ from those observed in patients receiving long term maintenance treatment with H2-receptor antagonists for ulcer disease. One hundred and thirty studies reported in the literature during the past three decades have been analysed to determine both the approximate rate of ulcer recurrence and the proportion of patients with recurrent ulcers who have presented with either haemorrhage or perforation following the various types of gastric surgery for ulcer disease. From these data, estimates of the risks of haemorrhage and of perforation during the years following gastric surgery have been calculated. Vagotomy and antrectomy is associated with a low risk of ulcer recurrence (less than 1%) and the risk of complications in later years is accordingly very small (less than 0.5%). Partial gastrectomy, although associated with low recurrence rates, has a higher risk of complications (1.3% for haemorrhage, 0.3% for perforation) because the proportion of recurrent ulcers that present with haemorrhage or perforation is high (33% and 8%, respectively). Truncal vagotomy plus drainage (TV + D) and highly selective vagotomy (HSV) are associated with recurrence rates of 9% and 12%, respectively, but ulcer recurrences following these operations are less frequently accompanied by complications then recurrences after gastric resection and, as a result, the risks of haemorrhage (1.7% for TV + D; 1.3% for HSV) are similar to the risks after gastric resection. During long term (five years or more) maintenance treatment with H2-receptor antagonists, the risks of haemorrhage and perforation are less than 2% and less than 0.5%, respectively. It appears, therefore, that the likelihood of developing haemorrhage or perforation following gastric surgery is of the same order as that during maintenance treatment with H2-receptor antagonists, at least during the first decade of follow-up.

[Ulcer anamnesis and gastroduodenoscopic findings--a contribution to the symptomatology of gastroduodenal ulcers].

513 patients who were gastroduodenoscopically examined on account of suspicion of ulcer were aimedly inquired for 18 typical ulcer complaints. Compared with patients with normal gastroduodenoscopic findings patients peptic ulcers of erosions of the gastric mucous membrane had significantly more frequently symptoms of the gastrointestinal haemorrhage, patients with ulcus ventriculi had, moreover, inappetence and vomiting, patients with duodenal ulcer a late pain in the centre of the epigastrium and in the right epigastrium. But these symptoms did not allow a significant differentiation between the patients with ventricular ulcer and duodenal ulcer. Patients without pathological gastroduodenoscopic findings had significantly more frequently an incompatibility of food and connected with this sensation of fullness. A typical symptomatology of ulcer may, indeed, be present in the individual case, but according to the results of the study it is no sufficient proof for the actual existence of a peptic ulcer and is thus of little differential-diagnostic value.
