Chronic gastric ulcer and stress. A comparison of an ulcer population with a control population regarding stressful events over a lifetime

The ulcer sleuths: The search for the cause of peptic ulcers

The search for the cause or causes of peptic ulcers has been a long one. It was recognised as early as the 19th Century that damage to the stomach or duodenal bulb was likely to result if the resistance of their mucosae to luminal acid was for some reason impaired. An early theory suggested microscopic vascular occlusion leading to local infarction could be the initiating event but evidence was lacking. Excessive acid secretion is seen in some patients but not in many so is implausible as the main factor in most ulcers. Cigarette smoking is a risk factor and chronic life difficulties has been shown to sometimes play a part, but we would now think that they play only minor roles to possibly tip the balance when a major etiologic factor is already present. The overwhelming evidence now is that the major etiologic factors in chronic peptic ulcer are ingestion of nonsteroidal anti-inflammatory drugs (NSAIDs) and infection with Helicobacter pylori. Understanding the mechanism of the first, and the discovery and demonstration of Koch's postulates for the second, have been instrumental in the award of two Nobel prizes.

Hypnosis and upper digestive function and disease

Hypnosis is a therapeutic technique that primarily involves attentive receptive concentration. Even though a small number of health professionals are trained in hypnosis and lingering myths and misconceptions associated with this method have hampered its widespread use to treat medical conditions, hypnotherapy has gained relevance as an effective treatment for irritable bowel syndrome not responsive to standard care. More recently, a few studies have addressed the potential influence of hypnosis on upper digestive function and disease. This paper reviews the efficacy of hypnosis in the modulation of upper digestive motor and secretory function. The present evidence of the effectiveness of hypnotherapy as a treatment for functional and organic diseases of the upper bowel is also summarized, coupled with a discussion of potential mechanisms of its therapeutic action.

The role of psychosocial factors in peptic ulcer disease: beyond Helicobacter pylori and NSAIDs

A variety of organic etiologies are associated with peptic ulcer disease, and the most relevant of these are infection with Helicobacter pylori and use of nonsteroidal anti-inflammatory drugs. Between 5% and 20% of patients with gastric or duodenal ulcer, however, lack an identifiable organic etiology. In these patients particularly and in all ulcer patients in general, psychosocial factors may play a significant role. At present, there is no definitive study proving a causal relationship between psychological stress and the development of ulcer disease. Studies to date suffer from significant methodological limitations and have not effectively addressed the poor correlation between ulcer craters and ulcer symptoms. A conservative application of available data would suggest that psychosocial factors play a significant role in symptom perception and reporting in patients with dyspeptic symptoms and may play a role in ulcer formation.

Peptic ulcers after the Hanshin-Awaji earthquake: increased incidence of bleeding gastric ulcers

OBJECTIVE

Although physical stresses are known to induce peptic ulcers in the upper gastrointestinal tract, it remains controversial whether emotional stress can cause peptic ulcers. Therefore, we examined retrospectively the influence of the Hanshin-Awaji earthquake that occurred in Japan in January 1995 on the occurrence of peptic ulcer disease among noninjured residents.

METHODS

Sixty-one hospitals, covering 70% of all endoscopy examinations performed in this area, joined the study and were divided into three areas according to the severity of the damage. A comparison was made between a group of 10,831 patients who underwent upper gastrointestinal endoscopy within 2 months after the earthquake and 16,100 who did so in the same hospitals during the corresponding period in 1994.

RESULTS

In the most devastated area, in spite of a dramatic decrease in the total number of endoscopies (50.0%), patients with gastric ulcer (GU) were increased in 1995, whereas those with duodenal ulcer were decreased, resulting in a higher ratio of gastric to duodenal ulcers than in 1994 (3.07 vs 1.88). In particular, there was a marked increase in bleeding GU. The mean age of patients with GU was significantly higher in 1995 than in 1994.

CONCLUSION

The Hanshin-Awaji earthquake-induced life event stress not only triggered but also exacerbated GU, particularly in the elderly.

Life events stress in Saudi peptic ulcer patients of the eastern province

The frequency of stress, as measured by the occurrence of 34 life events in the year preceding evaluation, was compared between 51 Saudis with peptic ulcers, diagnosed endoscopically, and 52 Saudis without peptic ulcer. All subjects were examined at King Fahd Hospital, Al-Khobar, Eastern Saudi Arabia, and were seen between March 1985 and July 1987. The mean number of events, their frequency distribution, and their categorization into areas of activity such as bereavement and other problems relating to health, marital, financial, and undesirable circumstances were similar for both groups. With regard to individual events, the only significant differences between ulcer patients and controls were that more patients had had serious arguments with in-laws or relatives and more controls had had minor personal illness or moderate financial problems. Excessive stress, as measured by life events, does not appear to be evident in Saudi peptic ulcer patients of the Eastern Province. Anxiety and/or depression was significantly more frequent in the group of patients with ulcers.

Controlled trial of hypnotherapy in relapse prevention of duodenal ulceration

30 patients with rapidly relapsing duodenal ulceration were studied to assess the possible benefit of hypnotherapy in relapse prevention. After the ulcer had healed on treatment with ranitidine, the drug was continued for a further 10 weeks during which time patients received either hypnotherapy or no hypnotherapy. The two randomly selected groups were comparable in terms of age, sex, smoking habits, and alcohol consumption. Follow-up of both groups of patients was continued for 12 months after the cessation of ranitidine. After 1 year, 8 (53%) of the hypnotherapy patients and 15 (100%) of the control subjects had relapsed. The results of this study suggest that hypnotherapy may be a useful therapeutic adjunct for some patients with chronic recurrent duodenal ulceration.

Life events stress and psychosocial factors in men with peptic ulcer disease. II. Relationships with serum pepsinogen concentrations and behavioral risk factors

We examined in a controlled study whether psychologic disturbances in men with peptic ulcer disease were related to other potential ulcer "risk factors" (serum pepsinogen concentrations, cigarette smoking, and intake of alcohol, aspirin, or coffee). Psychopathology in general, personality features of hostility, irritability, and hypersensitivity, and impaired coping ability (low ego strength) each correlated significantly with serum pepsinogen concentration in ulcer patients (p less than or equal to 0.005). Cigarette smoking and intake of alcohol and aspirin were increased in ulcer patients but unrelated to psychopathology. Depression was the variable that best discriminated ulcer patients from nonulcer controls; a negative perception of life events, number of relatives with ulcer, and serum pepsinogen I concentration also had a major, unique discriminating value, whereas smoking played a relatively minor role independent of the other variables examined. Our study supports the concept that several interacting factors (psychologic, behavioral, and genetic/physiologic) are likely involved in peptic ulcer disease. Emotional stress may predispose to ulcers by producing gastric hypersecretion, as manifested by hyperpepsinogenemia.

Life event stress and chronic difficulties in duodenal ulcer: a case control study

In a sample of consecutive ulcer (DU) patients and age, sex and social class matched normal controls, the prevalence of antecedent stressful life events in the two samples was similar. Antecedent chronic difficulties often lasting years were however significantly more common in the ulcer patients. Duodenal ulcer was more common in divorced, separated or widowed subjects; this finding was explained by the fact that these subjects had more chronic difficulties which predisposed to ulcer disease.

Life events stress and psychosocial factors in men with peptic ulcer disease. A multidimensional case-controlled study

We carried out a case-controlled study of multiple psychological and social factors in 49 men with complicated or uncomplicated peptic ulcer disease. Thirty-two men with renal stones or gallstones and 20 healthy men served as controls. Ulcer patients and controls experienced a similar number of potentially stressful life events. However, ulcer patients perceived their events more negatively (p less than 0.05). Ulcer patients also had significantly more personality disturbances than controls, although no one type of "ulcer personality" was found consistently. Some ulcer patients tended to be hypochondriacal complainers, overly pessimistic, and excessively dependent. Other personality disturbances were also more common in ulcer patients (e.g., immaturity, impulsivity, and feelings of social isolation and alienation). Ulcer patients had significantly lower ego strength and they had fewer friends and relatives whom they felt they could call upon in times of crisis. Finally, ulcer patients exhibited significantly more emotional distress in the form of depression and anxiety. Hypochondriasis, a negative perception of their life events, dependency, and lowered ego strength were the four variables that best discriminated ulcer patients from controls. This controlled study demonstrates a strong association between life events stress, psychosocial factors, and peptic ulcer disease.

Perception of life event stress in patients with chronic duodenal ulcer. A comparison of the rating of life events by duodenal ulcer patients and community controls

Stress is often claimed by doctors and patients to be an aetiological factor in peptic ulcer disease. The aim of the present study was to investigate whether ulcer patients perceive that they would react more strongly than normal to life event stress. Seventy-three patients with duodenal ulcer and their sex- and age-matched controls rated 81 events for the amount of distress and life change they considered the events would cause them personally. With regard to individual events, only one difference emerged: female patients rated promotion at work significantly lower for distress than did controls, when event experience was taken into account. There was a systematic tendency for ratings of male patients to be lower than those of controls. These observations suggest that duodenal ulcer patients do not perceive that their reaction to life events would be in excess of normal.

Goal frustration and life events in the aetiology of painful gastrointestinal disorder

Life events and difficulties were recorded for the year preceding onset of abdominal pain in 135 consecutive referrals to three gastrointestinal clinics, and for the equivalent time period in a matched, healthy community comparison series. Fifty-six patients were found to have an organic gastrointestinal disorder. Severely threatening events and major difficulties known to play a critical aetiological role in clinical depression, occurred with much the same frequency during the 38 weeks before onset of non-organic ('functional') gastrointestinal disorder. There was no such relationship between the severity of threat and organic disorder. A measure of 'goal frustration' reflecting the degree to which the subjects aims and ambitions were insurmountably obstructed by the occurrence of the event, was significantly associated with organic disorder. This finding may explain the often reported association between life stress and organic gastrointestinal disorder.
