Impaired accommodation of proximal stomach to a meal in functional dyspepsia

In patients with functional dyspepsia, scanning by a novel ultrasonographic method was carried out to investigate postprandial accommodation of the proximal stomach. Twenty patients with functional dyspepsia and 20 controls were scanned fasting in a sitting position after drinking 500 ml meat soup. Images were recorded up to 25 min after the ingestion period using an ultrasound sector scanner with a 3.25-MHz transducer. The area in a sagittal section and the maximal diameter in an oblique frontal section were chosen as the main variables for calculating the emptying fraction of the proximal stomach, defined as: (aV2.5min-aVactual/aV2.5min. All subjects were asked to score total symptoms (1–9) provoked by the meal. From 7.5 to 25 min after the ingestion period the patients exhibited both smaller area in the sagittal section (P<0.018) and shorter diameter in the frontal section (P<0.046) compared with healthy controls, and they suffered more symptoms in response to the meal (P=0.002). Dyspeptic patients revealed higher emptying fractions (P=0.0005, ANOVA), andH. pylori status did not influence the emptying fractions. Diagnostic sensitivity of the method at 20 min postprandially was 70% and the specificity was 65%. Patients with functional dyspepsia have impaired accommodation of the proximal stomach to a meal, temporarily related to symptom induction.

Psychological factors and somatic symptoms in functional dyspepsia. A comparison with duodenal ulcer and healthy controls.

One hundred patients with functional dyspepsia, 100 patients with duodenal ulcer and 100 healthy controls were assessed on anamnestic factors, somatic symptoms and psychological measures. Patients with functional dyspepsia had significantly higher levels of state-trait anxiety, general psychopathology, depression, a lower general level of functioning and more somatic complaints from different organ systems, especially the musculo-skeletal system, compared to patients with duodenal ulcer and healthy controls. Patients with functional dyspepsia had more frequent dyspepsia symptoms and a longer disease history than duodenal ulcer patients. Discriminant analyses using a model of fifteen psychological and anamnestic variables, classified correctly 71.5% of the subjects due to diagnoses. The test for multiple somatic complaints (Giessener Beschwerdebogen) was the most important discriminating factor (Eigenvalue 0.78). Seventy-five per cent of the patients were correctly classified, 71% by diagnosis with respect to diagnoses of duodenal ulcer and functional dyspepsia using frequency of dyspeptic symptoms as discriminating factor (Eigenvalue 0.40). Functional dyspepsia seems to be a disease entity of its own, distinct from duodenal ulcer and strongly associated with psychological factors.

Low vagal tone and antral dysmotility in patients with functional dyspepsia.

&NA; Effects of acute mental stress on gastric antral motility were investigated in 23 healthy persons and 25 patients with functional dyspepsia (FD). Real‐time ultrasonography of gastric antrum was recorded, after ingestion of 500 ml meat soup, during a 4‐min resting period, 2.5 min of mental stress, and a 4‐min recovery period. Amplitude of antral contractions was scored as a fraction of relaxed area. Motility‐index was calculated as the amplitude multiplied by frequency. Measurement of skin conductance reflected sympathetic tone, and respiratory sinus arrhythmia (RSA) was calculated to index vagal tone. Antral motility was reduced by mental stress in the healthy persons, but not in FD patients. Group differences were significant for amplitude (p < 0.002) and motility‐index scores (p < 0.02). Sympathetic tone increased during stress in both groups. Vagal tone was lower in the FD patients than in the healthy controls (p < 0.001). The lack of stress‐related reduction of motility among patients with FD may, therefore, be a consequence of poor vagal tone.

Background : Somatic comorbid symptoms might identify irritable bowel syndrome patients with different aetiologies and needs of treatment.

Low vagal activity as mediating mechanism for the relationship between personality factors and gastric symptoms in functional dyspepsia

&NA; Low vagal tone may represent a mediating mechanism for relationships between personality and symptoms of functional dyspepsia (FD) through a mechanism of antral hypomotility. Twenty‐one patients with FD and seventeen healthy controls completed a series of personality tests before vagal and sympathetic activity, antral motility, and abdominal symptoms were assessed in response to a laboratory task. Functional dyspepsia patients had lower scores on vagal tone (p = .054) and motility index (p = .011) in addition to the expected higher scores on epigastric discomfort (p = .002). Psychological factors explained a substantial amount of the variance in vagal activity, antral motility, and reported symptoms. Symptoms were predicted by trait anxiety (STAI‐TR), depression (BDI), and neuroticism (EPQ‐N). Poor vagal tone was related to neuroticism (EPQ‐N). Poor motility was best explained by task‐related state dysphoria (SACL‐STR).

Life Events and Stress in Patients with Functional Dyspepsia Compared with Patients with Duodenal Ulcer and Healthy Controls

BACKGROUND Life events and stress may be important for functional dyspepsia and duodenal ulcer. METHODS The perception of life events in the preceding 6 months was recorded in 100 patients with functional dyspepsia, 100 patients with duodenal ulcer, and 100 healthy controls. In addition, psychologic and social factors were assessed. RESULTS Patients with functional dyspepsia experienced significantly more life events than patients with duodenal ulcer and healthy controls. The difference in life events between the groups was due to the difference in stressful life events. The patients with functional dyspepsia had higher levels of state-trait anxiety, general psychopathology, and depression than patients with duodenal ulcer and healthy controls. CONCLUSION Patients with functional dyspepsia had higher scores on negative life events than patients with duodenal ulcer and healthy controls. This may be causally related to the higher levels of anxiety, depression, and general psychopathology in these patients.

Discriminant analysis of factors distinguishing patients with functional dyspepsia from patients with duodenal ulcer: Significance of somatization

Patients with duodenal ulcer or functional dyspepsia do not differ on dyspeptic symptoms. The aim of the present study was to test the hypothesis that functional dyspepsia and duodenal ulcer are two different diagnostic entities by examining the discriminating power of several anamnestic, biological, and psychosocial variables. Ninety-four patients with duodenal ulcer and 86 patients with functional dyspepsia were included. Anamnestic data, global assessment,Helicobacter pylori status, blood group, Lewisa+ phenotype, and several measures of psychological distress and somatic complaints were registered. Compared to patients with functional dyspepsia, the duodenal ulcer patients were more often infected byHelicobacter pylori and had their stomach discomfort more often relieved by eating. Compared to patients with duodenal ulcer, patients with functional dyspepsia had higher scores of depression, trait anxiety, general psychopathology and different somatic complaints (called somatization). They were also less satisfied with the health care system, their disorder had a greater negative impact on their quality of life, and their global assessment of own health was poorer. Discriminant analysis including age, smoking,Helicobacter pylori status, global assessment, and somatic complaint classified 86.1% of the patients correctly (77.9% of the patients with functional dyspepsia and 93.6% of the patients with duodenal ulcer). It is concluded that duodenal ulcer and functional dyspepsia are two separate diagnostic entities. Patients with duodenal ulcer are older, smoke more often, and almost all are infected withHelicobacter pylori, while patients with functional dyspepsia are characterized by somatization and a negative assessment of their own health.

INSPIRE study: Does stress management improve the course of inflammatory bowel disease and disease‐specific quality of life in distressed patients with ulcerative colitis or crohn's disease? A randomized controlled trial

Background: The use of stress management psychotherapy is hypothesized to produce greater improvement in disease course and disease‐specific quality of life (IBDQ) compared to usual medical care alone in patients with ulcerative colitis (UC) or Crohns disease (CD) showing high levels of stress (based on the Perceived Stress Questionnaire [PSQ]). Methods: Fifty‐eight patients with UC and 56 patients with CD who had experienced continuous disease activity or had relapsed over the previous 18 months, with an activity index for UC or CD ≥4, a PSQ ≥60, and without serious psychiatric disorders or other serious medical conditions were randomized to receive either treatment as usual (TAU) or TAU plus stress management psychotherapy. Psychotherapy consisted of three group sessions (psychoeducation, problem‐solving, relaxation) and 6–9 individual sessions based on cognitive behavior therapy‐related methods with 1–3 booster sessions at 6 and 12 months follow‐up. Gastroenterologists blinded to intervention group assessed disease activity and course at baseline and at 3, 6, 12, and 18 months. Patients completed the IBDQ at baseline, 6, 12, and 18 months. Results: The intervention did not improve disease or reduce relapse; however, it increased the IBDQ score (P = 0.009, mean differences 16.3 [SD 6.1]). On analysis of UC and CD separately, improvement of IBDQ was only found in the UC group. Conclusions: Stress management psychotherapy does not appear to improve disease course or reduce relapse in patients with IBD. It might improve quality of life, particularly in patients with UC.

Health anxiety and disability pension award: The HUSK Study.

Objective: To examine the hypothesized effect of health anxiety on subsequent disability pension award. Mental disorders are consistently underrecognized in general health care, leading to underestimation of its effects on related social security expenditures. According to medicolegal diagnoses for disability pension award, there are almost no awards of disability benefits for health anxiety or hypochondriasis. There are no empirical longitudinal population-based studies on occupational disability in health anxiety or the extreme of hypochondriasis. Methods: Using a historical cohort design, we utilized a unique link between a large epidemiological cohort study (n = 6819) and a comprehensive national database of disability benefits to examine the effect of health anxiety on subsequent disability pension award (n = 277) during 1.0 to 6.6 years of follow-up. The data sources were merged after informed consent, using the national personal identification number. Results: Health anxiety was a strong predictor of disability pension award, exceeding the effect of general anxiety, and comparable to the effect of depression. This effect was partly accounted for by adjustment for income and level of education, and comorbid mental, psychosomatic, or physical conditions. The effect was not limited to high symptom levels, but followed a dose-response association. Despite the robust effect in this prospective study, health anxiety or hypochondriasis was not recognized as medicolegal diagnosis for any awards of disability pension, and was not accounted for by other mental disorders. Conclusions: Health anxiety is a strong, independent, and yet underrecognized risk factor for disability pension award.

Quality of Life and Relapse of Duodenal Ulcer before and after Eradication of Helicobacter pylori

BACKGROUND The aim of the study was to compare relapse rates and quality of life before and after eradication of Helicobacter pylori in a group of patients with documented recurrent duodenal ulcer disease. METHODS Seventy-four patients with three endoscopically verified duodenal ulcers during the past 2 years received triple treatment consisting of bismuth subnitrate, oxytetracycline, and metronidazole for 14 days. Quality of life was measured with the Psychosocial Adjustment to Illness Scale (PAIS-SR) and H. pylori status with the 14C-urea breath test. RESULTS After triple treatment H. pylori was eradicated in 96%, and the ulcer was healed in all. Ulcer relapse was reduced from 100% before to 1.4% during a mean observation time of 111 weeks. The H. pylori reinfection rate was 2.4% during the 1st year. The patients were more satisfied with the health care system and had better sexual relationship and less psychologic distress 1 year after eradication of H. pylori than before. CONCLUSIONS For patients with recurrent duodenal ulcer, eradication of H. pylori with triple treatment leads to a significantly reduced ulcer relapse rate and improved quality of life.
