Helicobacter pylori infection and peptic ulcer disease in cirrhosis

An increased frequency of peptic ulcer disease is noted in patients with cirrhosis, but the role of H. pylori in this disorder remains to be determined. The diagnosis of cirrhosis was confirmed by a combination of clinical, biochemical, radiological, and histological methods. The severity of cirrhosis was assessed by Pugh's modification of Child's criteria. Upper gastrointestinal endoscopy was performed consecutively to evaluate the presence of varices and gastroduodenal mucosa. H. pylori status was assessed by histology, urease test, and serology. In all, 130 patients with cirrhosis were recruited into the study; there were 86 males and 44 females with a mean (SD) age of 54.4 (12.7) years. The H. pylori prevalence was 76.2%. There was no difference in age between the H. pylori-positive and -negative cirrhotics (P = 0.29). The H. pylori prevalence revealed no difference among cirrhotics with Child A (77.8%), Child B (72.9%), and Child C (78.6%) (P = 0.8), and neither was there a difference in H. pylori prevalence in cirrhotics with and without congestive gastropathy (77% vs 73.7%, P = 0.84). The prevalence of H. pylori in cirrhotics with and without varices did not show a statistical difference (75% vs 81.8%, P = 0.68). There also was no difference in the H. pylori prevalence between cirrhotic patients with and without peptic ulcers (84.4% vs 69.7%, P = 0.09). In conclusion, the prevalence of H. pylori or peptic ulcer is independent of the severity of cirrhotic liver disease. The association between H. pylori infection and peptic ulcer disease is weak in cirrhosis.     

The significance of gastric helicobacteriosis in the genesis hemorrhage from duodenal peptic ulcer

Based on a comprehensive analysis of findings from examination and surgical treatment of 196 patients with bleeding pyloroduodenal ulcers, it was found out that patients with concurrent helicobacteriosis of the stomach are prone to more unfavourable course of their illness, which fact is evidenced by a greater loss of blood and higher risk for bleeding recurrences. A classification is proposed by the authors, taking advantage of the data from endoscopic, microscopic and immunoenzymatic techniques, with the purpose of providing an assessment of degree of severity of helicobacteriosis of the stomach.     

The etiological and pathogenetic characteristics of duodenal peptic ulcer in adolescents

Studied by endoscopy were 100 adolescents with diagnosed duodenal ulcer, as were 100 essentially healthy subjects and 90 ones of the same age presenting with primary chronic gastroduodenitis together with 60 adults who had duodenal ulcer. The following items were etiologic risk factors for duodenal ulcer, if combined, in the above adolescent series: Frequent episodes nervous of tension, hereditary predisposition and helicobacteriosis. In juveniles with duodenal ulcer, secretion and motility of the stomach appeared to be subjected to changes to a higher degree than it was in adult subjects with duodenal ulcer, while functions of the psychovegetative and immune systems were found to be less changeable in the former. In adolescents presenting with duodenal ulcer and primary chronic gastroduodenitis, the etiologic risk factors and pathogenetic changes were found out to be identical.     

Immune status indices during the combined treatment of patients with duodenal peptic ulcer

Indices were studied of the immunological status (cell-mediated, humoral immunity) before and after the multimodality pathogenetic treatment of patients with duodenal ulcer. Noted in the course of the complex treatment were changes in the immunoregulatory index, NK-cells, IgM. The findings obtained suggest that the immune defence may be depressed, with the vascular factor, infection (Helicobacter pylori) having their part in the genesis of duodenal ulcer.     

Functional results of surgical repair of chronic duodenal insufficiency associated with duodenal ulcer

The results of 312 patients examination in late follow-up period after conduction of the organ preserving intervention, gastric resection and reconstructive operation with chronic duodenal insufficiency correction, concurrent with duodenal ulcer, its acute complications, postvagotomy and postresection syndrome are adduced. An excellent and good result was noted in 70.2% of patients, fair--in 23.4%, bad--in 6.4%.     

High prevalence of Helicobacter pylori in liver cirrhosis: relationship with clinical and endoscopic features and the risk of peptic ulcer

In 153 consecutive patients with cirrhosis we assessed: (1) the prevalence of IgG to Helicobacter pylori and compared it with that found in 1010 blood donors resident in the same area; and (2) the relationships of IgG to Helicobacter pylori with clinical and endoscopic features and with the risk of peptic ulcer. The IgG to Helicobacter pylori prevalence of cirrhotics was significantly higher than in blood donors (76.5% vs 41.8%; P < 0.0005) and was not associated with sex, cirrhosis etiology, Child class, gammaglobulins and hypertensive gastropathy. In both groups, the prevalence of IgG to Helicobacter pylori was significantly higher in subjects over 40. Among patients with cirrhosis a significantly higher prevalence of Helicobacter pylori was found in patients with previous hospital admission (P = 0.02) and/or upper gastrointestinal endoscopy (P = 0.01) and patients with peptic ulcer (P = 0.0004). Multivariate analysis identified increasing age and male sex as risk factors for a positive Helicobacter pylori serology and no independent risk factors for peptic ulcer. The high prevalence of Helicobacter pylori-positive serology found in the present series is related to age and sex and might also be explained by previous hospital admissions and/or upper gastrointestinal endoscopy. Our results do not confirm the role of Helicobacter pylori as risk factor for peptic ulcer in patients with liver cirrhosis.     

A trial of the use of Maldroxal in treating patients with duodenal peptic ulcer

A 67 year old man presented with non-invasive thymoma, associated aplastic anemia and important hypogammaglobulinemia; the postoperative course has been characterized, three months later, by thrombocytopenia (kept under control with steroid therapy) and, two years later, by squamous lung cancer, not susceptible of surgical treatment. The patient died five years after operation because of progression of the lung cancer. Anemia improved only partially after operation; there where no effects on hypogammaglobulinemia. Thymoma has been reported in literature in 50% of patients with aplastic anemia, 7-13% of adult patients with hypogammaglobulinemia is affected by thymoma, in 21% of patients that presented with thymoma other tumors have been discovered through clinical history.     

Surgical treatment of acute peptic hemorrhage associated with perforation of gastroduodenal ulcer

In 1982-1996 yrs of 8822 patients with ulcer bleeding in 122 (1.4%) it was concurrent with gastroduodenal ulcer perforation. In 34 (27.9%) simultaneous perforation and bleeding were observed, in 88 (72.1%) perforation occurred in 1-7 days after bleeding, in 48 (54.5%) it was concurrent with recurrent bleeding. Postoperative mortality lowered from 25 to 7.1% due to application of the principles elaborated.     

Selective proximal vagotomy with duodenoplasty in the treatment of duodenal stenosis in patients with duodenal ulcer]

The results of surgical treatment of 118 patients with duodenal ulcer complicated with stenosis that have been operated on from 1981 to 1992 have been analysed. Selective proximal vagotomy (SPV) and duodenoplasty was performed in 58 (49.2%) patients (study group). SPV and gastroduodenal anastomosis by the method of Jabulay was performed in 60 (50.8%)-control group. The rate of postoperative morbidity in the study group-5.1%, in the control group-8.4%. The long-term follow up is from 1 year to 10 years (mean 5 + 0.6). The rate of recurrence of peptic ulcer is 8.6% in the study group and 10% in the control group. The modified scale (D. Johnson, 1976) was used for comparative evaluation of efficacy of two types of surgery. SPV and duodenoplasty was estimated in 175.1 points, that is 2.5 times less that SPV and gastroduodenal anastomosis (406.1 points). This demonstrates the advantages of SPV and duodenoplasty. The authors advocate SPV and duodenoplasty as a method of choice in the treatment of stenotic duodenal ulcer.     

The use of pylorus-sparing operations in treating duodenal peptic ulcer complicated by stenosis

Based on an analysis of immediate (388 patients) and long-term (259 patients) results of surgical treatment of ulcer disease of the duodenum complicated by stenosis the authors made a conclusion that selective proximal vagotomy in combination with dissection of the ulcer substrate (the stenosis area) without injuries of the pyloric constrictor is the operation of choice in treatment of ulcerous duodenal stenosis resulting in less lethality (0.52%), in practical exclusion of the development of functional disorders and impaired nutrition of the patients.     

Endotoxinemia in liver cirrhosis]

Ribosomes isolated from either dry viable or non-viable pea embryonic axis tissue were equally effective in the support of polyphenylalanine synthesis in a poly(U)-directed cell-free protein-synthesising system. Ribosomes isolated from imbibed non-viable axis tissue were impaired in their ability to support polyphenylalanine synthesis in the cell-free system. RNA isolated from ribosomes and 40-S ribosomal subunits of dry or imbibed viable axis tissue was found not to be degraded, whereas the equivalent RNA species isolated from non-viable axis tissue showed an increased degree of breakdown as imbibition proceeded. Even though rRNA of imbibed non-viable axis tissue was degraded, the ribosomes and ribosomal subunits of these embryos appeared intact. In viable embryonic axis tissue the percentage of ribosomes present in the cell in the form of polysomes increased during imbibition whereas no polysomes could be detected in ribosomal preparations from dry or imbibed non-viable axis tissue. The breakdown of rRNA in ribosomal particles from non-viable axis tissue may be a contributory factor to senescence and loss of viability in Pisum arvense.     

Histamine and peptic ulcer: a prospective study of mucosal histamine concentration in duodenal ulcer patients and in control subjects suffering from various gastrointestinal diseases

In a prospective study the histamine content of the mucosa of the body of the stomach was measured in 100 patients consisting of control subjects, patients with duodenal ulcer and patients suffering from various gastrointestinal diseases. The histamine content was found to be 43 mug/g in male control subjects (median) while in duodenal ulcer patients levels attained were significantly lower by about 30 per cent. In all the other groups of patients histamine concentrations in gastric mucosa were found to be "normal". Since in most species it is extremely diffcult to alter the mucosal histamine concentration by any form of treatment, the diminished histamine content of the gastric mucosa in patients with duodenal ulcer seems remarkable. Among several possible explanations offered for this finding we think the most likely is that histamine release is increased in duodenal ulcer disease.     

Surgical treatment of duodenal ulcer with chronic duodenal obstruction

Follow-up treatment results of 892 patients with duodenal ulcer (DU) are presented and the choice of surgical policy in its combination with chronic duodenal obstruction (CDO) in 307 (34.4%) patients is substantiated. Depending on peculiarities of DU, the kind and the stage of CDO, organ saving (140) or stomach resection (167) in combination with correction CDO interventions (287) were carried out. The course of the postoperative period was characterised by basic morphofunctional changes and by achievement of completeness of duodenal passage. Intermittent motor-evacuatory disorders were observed in 55 (17.9%) patients. Lethal outcome was in 1 case. Long-term functional results of the operations were studied in 267 patients. Excellent and good results were obtained in 66.3%, favorable-in 32.24% and unfavorable-in 1.44% of patients. The dependence of immediate and remote results of the operations on the effectiveness of the correction of associated CDO was established.
