Abnormalities in gastrointestinal motility have been reported in a substantial proportion of patients with functional dyspepsia, supporting the use of prokinetic drugs for treatment of dyspeptic symptoms. To evaluate efficacy and safety of levosulpiride in short-term treatment, 1298 patients were enrolled in a double-blind multicentric study carried out in 45 Italian Gastroenterology Departments. Patients were randomly assigned to either levosulpiride (25 mg tid), domperidone (10 mg tid), metoclopramide (10 mg tid) or placebo (1 tablet tid) for 4 weeks. Patients were selected on the basis of: a) occurrence in the last 4 weeks of at least 5/10 selected symptoms (anorexia, nausea, vomiting, upper abdominal pain, postprandial bloating, abdominal fullness, early satiety, belching, heartburn, regurgitation), severity of which should reach/exceed a total score of 8, as assessed by a specific scale ranging from 0 (absent) to 3 (severe); b) normal results of routine biochemical, ultrasound and endoscopic examinations. In addition, each patient subjectively evaluated efficacy of treatment by a visual analogue scale. Significant improvement was recorded for all symptoms at days 10 and 28 in all groups (p < 0.001), but levosulpiride was significantly (p < 0.01) superior to domperidone, metoclopramide and placebo both in the overall clinical improvement scale as well as in a subgroup of symptoms (postprandial bloating, epigastric pain, heartburn). Active treatments and placebo were comparable as far as concerns occurrence of side-effects (12-20%) including galactorrhoea, breast tenderness and menstrual changes.

Cyclospora cayetanensis, a coccidian parasite, is a new cause of prolonged diarrhea. It has been most recently associated with ingestion of contaminated fruit. Although infection with C. cayetanensis is considered rare, the exact prevalence in Canada is unknown. Transmission is thought to occur through contaminated food and water. The incubation period varies from days to weeks. Patients present with nausea, vomiting, anorexia, bloating, abdominal cramping, increased gas and watery diarrhea. The illness may last up to 6 weeks and may respond to treatment with trimethoprim-sulfamethoxazole. C. cayetanensis is differentiated from other coccidians by its sporulation characteristics and its autofluorescence. To obtain a positive result of a laboratory test for the organism, a modified Ziehl-Neelsen acid-fast stain is recommended. Proper laboratory handling of specimens is facilitated by inclusion of clinical information on requisition forms.

Chronic pancreatitis is commonly included among the organic causes of dyspepsia, however the frequency and characteristics of this association are ill-defined. One-hundred-fifteen consecutive patients with chronic pancreatitis and 85 healthy subjects were interviewed regarding their clinical history, with particular attention to dyspeptic symptoms. Attacks of prolonged upper abdominal pain, recurring at unpredictable intervals and in most cases without identifiable triggering factors, were the most frequent clinical manifestation (108, 94%). During the attacks, many patients (66, 61%) complained of vomiting, which was generally mild and of brief duration. Between the attacks, very few patients (12, 10%) complained of dyspeptic disturbances, mainly postprandial epigastric fullness and abdominal bloating. These complaints were episodic, usually after abundant meals, in 8, and persistent in the remaining 4. Among these 12 patients, there were no significant differences in the frequency of dyspeptic symptoms in relation to the severity of exocrine pancreatic insufficiency. The frequency of dyspeptic complaints among patients (10%) was significantly lower (p < 0.01) than the frequency of dyspeptic symptoms among the controls (25%). The results of this study indicate that, other than recurrent attacks of abdominal pain, dyspeptic symptoms are uncommon in chronic pancreatitis, and that impairment of digestion of pancreatic origin is not a cause of dyspepsia.

Cisapride is a substituted benzamide with gastrointestinal prokinetic effects presumed to be due to the enhancement of the physiological release of acetylcholine at the myenteric plexus. In a multicentre study, 189 patients with nonulcer dyspepsia (NUD) received single-blind placebo treatment for two weeks. A total of 123 patients with no or minimal response to placebo and epigastric pain of at least moderate severity and frequency were randomly assigned to one of the three parallel double-blind treatments for six weeks: cisapride 10 mg tid, cisapride 20 mg tid or placebo. The severity and frequency of individual symptoms (epigastric pain, heartburn, nausea, vomiting anorexia, postprandial discomfort, regurgitation, lower abdominal pain, bloating and constipation) were assessed on a four- and five-point categorical scale, respectively, by the investigator at three on treatment visits and by patients in a daily diary. Analysis of investigator and patient assessments for differences in symptom severity x frequency composite scores among the three treatment groups showed no statistically significant differences for individual symptoms or symptom clusters. As assessed by the investigator, and compared with baseline, cisapride 20 mg tid significantly (P < 0.05) improved epigastric pain, bloating and early satiety as well as improved the total symptom cluster. Investigator evaluation of the five most severe and frequent symptoms for each patient showed statistically significant improvement in each treatment group. For patient diary assessments, statistically significant within-treatment improvement of the total symptom cluster, the five most severe symptoms cluster, bloating and early satiety was observed for both cisapride 20 mg and placebo, whereas epigastric pain significantly (P < 0.05) improved in all three treatment groups. Investigator evaluation of global response (good+excellent) rate at the end of the six week treatment period was 38% for cisapride 20 mg, 47% for cisapride 10 mg and 33% for placebo. No statistically significant difference in this parameter among treatments was noted. Cisapride was well tolerated at both doses with a side effect profile comparable with that of placebo. It is concluded that in this double-blind multicentre study with a single-blind two-week placebo run in phase, cisapride 10 mg tid and 20 mg tid were not effective compared with placebo in improving symptoms in NUD patients. This study re-emphasizes the good prognosis of patients with NUD, with 14% of patients improving in the two-week placebo run-in phase and a further 33% improving in the next six weeks while on placebo. Within-treatment analysis of investigator assessments showed improvement for cisapride 20 mg tid suggesting a trend of efficacy at this dose.

The effect of long-term cisapride therapy (20 mg orally three times daily for 2 years) on gastric emptying and gastrointestinal symptoms was investigated in 30 patients with severe gastroparesis (24 idiopathic, 6 diabetic). Symptoms were assessed every 2 months, using an overall symptom score based on six symptoms (anorexia, nausea, vomiting, pain, early satiety and bloating), and a 2-year mean overall symptom score was used for analysis. Gastric emptying was measured at 0, 6, 12, 18 and 24 months. Of the 24 patients who completed the study, 10 showed a significant improvement in gastric emptying (P < 0.05) and felt improved on therapy, seven patients showing a > 20% improvement in overall symptom score compared to baseline. Results for 15 patients who underwent at least one follow-up gastric-emptying test showed only a weak correlation between individual symptom score and gastric emptying (r = 0.40). Thus long-term cisapride therapy at the study dose produced long-term symptomatic improvement in 42% of patients with severe gastroparesis, with sustained acceleration of gastric emptying for up to 2 years.

This study investigated whether domperidone could improve gastrointestinal symptoms in patients with Parkinson's disease who were receiving levodopa therapy. A total of 11 patients were studied. Following a baseline gastric emptying test, patients were treated with a starting dose of domperidone 20 mg p.o. q.i.d. A follow-up gastric emptying test was repeated at least 4 months after starting domperidone therapy. At the beginning and at each 3-month follow-up visit, symptoms of nausea, vomiting, anorexia, abdominal bloating, heartburn, regurgitation, dysphagia, and constipation were evaluated and scored on a scale of 0-3. The overall mean follow-up period was 3 years. Compared with their baseline evaluation, patients experienced a significant improvement in all symptoms (p < 0.05) except dysphagia and constipation. Gastric emptying of an isotope-labeled solid meal was significantly faster, with a baseline result of 60.2 +/- 6.4% retention of isotope 2 h after the meal compared with 37.0 +/- 2.2% retention during domperidone therapy (p < 0.05). Patients' global assessment of Parkinson's disease remained stable or improved. Serum prolactin was elevated in all patients after domperidone therapy (p < 0.05). Domperidone therapy significantly reduces upper gastrointestinal symptoms and accelerates gastric emptying of a solid meal, but does not interfere with response to antiparkinsonism treatment.

Dyspepsia is a vague term for the nonspecific symptoms of upper abdominal discomfort, prolonged postprandial fullness or early satiety, nausea, vomiting, and upper abdominal bloating. Many common and accepted diseases and disorders such as gastroesophageal reflux and irritable bowel syndrome cause dyspepsia symptoms; these disorders should be identified and treated. However, many patients with dyspepsia symptoms have normal radiographic and endoscopic evaluations; in these patients, neuromuscular of functional disorders of the stomach ranging from gastric dysrhythmias to gastroparesis may be the cause of dyspepsia symptoms. A practical approach to the evaluation and treatment of dyspepsia symptoms attributed to gastric neuromuscular dysfunction of unknown origin is described.

The expectation that cholecystectomy is effective treatment for symptomatic gallstones is not always achieved in surgical practice. The impact of cholecystectomy on the relief of gastrointestinal symptoms was evaluated in 92 patients followed up after surgery for a mean of 31.1 months (range 12-83 months). Abdominal pain continued to be present, or arose de novo, in 28 (30.4%) patients. Pain-free outcome after cholecystectomy was associated with a preoperative clinical diagnosis of biliary colic, fatty food intolerance, and a thick-walled gallbladder on ultrasound (P = 0.02). Logistic regression associated a thick-walled gallbladder, elevated gamma-glutamyl transpetidase, body mass index < 26, fat intolerance, and normal bowel habit with good postoperative results (P = 0.001). Application of each of these five factors to a clinical index failed to predict long-term pain-free outcome after cholecystectomy. Abdominal bloating (P = 0.03), dyspepsia (P < 0.001), heartburn (P < 0.007), fat intolerance (P < 0.001), nausea (P = 0.001) and vomiting (P < 0.001) were significantly improved after cholecystectomy, but diarrhoea, constipation and excessive flatus were not. Outcome benefit ratios confirmed that vomiting (0.96), nausea (0.87), dyspepsia (0.67), fat intolerance (0.57) and heartburn (0.51) were relieved by surgery. Cholecystectomy improved symptoms compared with a matched control group, suggesting that surgery remains the gold standard treatment of symptomatic gallstones.

With the advent of minimally invasive techniques, the surgical treatment of gastroesophageal reflux disease has received renewed interest. The efficacy of laparoscopic Nissen fundoplication in eliminating reflux has been documented. This study was undertaken to determine changes in quality of life and cost of antireflux medications after laparoscopic Nissen fundoplication. One hundred patients undergoing laparoscopic Nissen fundoplication between 1992 and 1997 completed questionnaires assessing changes in pre- and postoperative cost and number of antireflux medications, reflux symptoms, and quality of life. The average number of antireflux medications was significantly reduced (1.8 versus 0.3, P < 0.0001) as was the average monthly cost ($170 versus $30, P < 0.0001). Patients reported significant (P < 0.05) symptomatic improvement in postprandial heartburn, nocturnal heartburn, postprandial nausea, postprandial vomiting, dysphagia, and gas/bloating. Patients in this series noted fewer symptoms and used fewer antireflux medications at less cost after laparoscopic Nissen fundoplication. Symptoms commonly thought of as complications of fundoplication (vomiting, dysphagia, gas/bloating) were less common after fundoplication. This report documents the efficacy of laparoscopic fundoplication in improving quality of life and reducing use and cost of antireflux medications.

We have previously reported impressive results in using a gonadotropin-releasing hormone analog, leuprolide acetate (Lupron), in the treatment of moderate to severe symptoms (especially abdominal pain and nausea) in patients with functional bowel disease (FBD). Pain is the hallmark of patients with FBD, and there is no consistent therapy for the treatment of these patients. The purpose of the present study was to expand the investigation to study similar patients (menstruating females) in a multicenter, double-blind, placebo-controlled, randomized study using Lupron Depot (which delivers a continuous dose of drug for one month), 3.75 mg (N = 32) or 7.5 mg (N = 33), or placebo (N = 35) given intramuscularly every four weeks for 16 weeks. Symptoms were assessed using daily diary cards to record abdominal pain, nausea, vomiting, early satiety, anorexia, bloating, and altered bowel habits. Additional assessment tools were quality of life questionnaires, psychological profile, oral-to-cecal transit using the hydrogen breath test, antroduodenal manometry, reproductive hormone levels, and global evaluations by both patient and investigator. Patients in both Lupron Depot-treated groups showed consistent improvement in symptoms; however, only the Lupron Depot 7.5 mg group showed a significant improvement for abdominal pain and nausea compared to placebo (P < 0.001). Patient quality of life assessments and global evaluations completed by both patient and investigators were highly significant compared to placebo (P < 0.001). All reproductive hormone levels significantly decreased for both Lupron Depot-treated groups by week 4 and were significantly different compared to placebo at week 16 (P < 0.001). This study shows that leuprolide acetate is effective in controlling the debilitating symptoms of abdominal pain and nausea in patients with FBD.
