Thirty patients with leukemia and lymphoma have been treated at our institution with high doses of cytosine arabinoside (Ara-C). Gastrointestinal symptoms were frequent after therapy, and 6 of the 30 patients had severe abdominal pain. Of the six, two had pancreatitis; two had normal amylase and lipase determinations; and in two, neither amylase nor lipase levels were determined. The two patients with pancreatitis are presented because this complication of high-dose Ara-C therapy has not been described. The authors conclude that pancreatitis can follow high-dose Ara-C chemotherapy and that patients with abdominal pain following this treatment be evaluated for pancreatitis.

Gastrointestinal symptoms are a common feature of Addison's disease, but the diagnosis may be delayed because of the nonspecific nature of the symptoms. This report describes nine patients with Addison's disease who presented to our unit over the past 3 yr. Eight had severe or unusual gastrointestinal symptoms at presentation. One, already known to have Addison's disease, required several admissions to the hospital because of unexplained abdominal pain and vomiting before inadequate glucocorticoid replacement was diagnosed. All but one had previously attended the hospital, but the diagnosis of Addison's disease had been overlooked. Five eventually presented in crisis. It is important to exclude Addison's disease in all patients with unexplained abdominal symptoms.

Gastrointestinal symptoms have been the most frequently reported adverse experiences in the misoprostol (Cytotec) studies of both patients with peptic ulcer disease, and healthy subjects. There have been relatively few cardiovascular, genito-urinary, or other adverse effects. This is similar to the results of animal studies in which misoprostol had little, if any, effects on cardiovascular, central nervous, and endocrine systems. The predominant activity of misoprostol in the gastrointestinal tract, essential to its ulcer-healing activity, may also account in part for the association of misoprostol with gastrointestinal adverse experiences. Abnormal bowel movements were the most common complaint (9-13%) of patients in pivotal controlled studies. In patients taking misoprostol 200 micrograms four times daily, 7.1% had diarrhea, with less than 1% stopping therapy because of diarrhea. Abdominal pain in these patients was reported in an incidence of 12.8%, was mild, and only rarely resulted in stopping therapy. Other adverse reactions reported in these patients were nausea, headache, and dizziness. In pregnant women, undergoing a legal termination of pregnancy, it has been shown that misoprostol has a greater incidence of uterine bleeding, and partial or complete expulsion of uterine contents, than placebo. Misoprostol (Cytotec) has received government approval for marketing in 12 countries, since the first gave its approval in June, 1984. It has been launched in 6 of those markets to date, with an estimated 100,000 patients having taken the drug. No serious adverse experiences attributed to misoprostol have been reported, but mild adverse experiences have occurred. Those most frequently reported were gastrointestinal in nature, and included diarrhea, abdominal pain, and nausea.(ABSTRACT TRUNCATED AT 250 WORDS)

In 16 consecutive patients with systemic mastocytosis, we prospectively evaluated a variety of gastrointestinal functions and examined how they relate to the occurrence of gastrointestinal symptoms. Nine patients had either a duodenal ulcer or duodenitis. Hypersecretion of gastric acid was present in 6 patients, and in these patients the mean basal acid output was 20.7 +/- 4.1 mEq/h (range 14-39 mEq/h). Impaired small intestinal absorption occurred in 5 patients, although this was usually mild. The mean fractional emptying rate of liquids for all patients (14.7% +/- 2.3% per minute) did not differ from that for controls (10.7% +/- 0.6% per minute). Mean mouth-to-cecum transit time measured by breath hydrogen testing was the same among patients (87.7 +/- 6.7 min) and controls (86.7 +/- 8.0 min). Plasma histamine concentrations were increased in all patients (mean 1886 pg/ml, range 480-7450) and correlated with the basal acid output (r = 0.64, p less than 0.02) but not maximal acid output or the presence or absence of pain or diarrhea. Mean fasting plasma concentrations of motilin, substance P, and neurotensin from 6 patients did not differ significantly from controls, whereas gastrin and vasoactive intestinal peptide were significantly less than in controls (p less than 0.01). Gastrointestinal symptoms, consisting of abdominal pain or diarrhea, occurred in 80% of patients. Abdominal pain classified as dyspeptic was usually associated with acid-peptic disease of the duodenum and hypersecretion of gastric acid, whereas abdominal pain of a nondyspeptic character was not. Only in those cases of diarrhea consisting of greater than 200 g stool/day was gastric acid hypersecretion frequently found. Neither fecal urgency nor nondyspeptic pain could be accounted for by alterations of gastrointestinal transit. These results demonstrate that gastrointestinal symptoms, peptic disease, and mild malabsorption are much more common than described previously in patients with systemic mastocytosis. Furthermore, the results provide no evidence for the contention that altered gastrointestinal transit is involved in the pathogenesis of these symptoms.

Local and systemic side effects of clofazimine in 514 Leprosy and 26 vitiligo patients who had taken the drug in different doses (100 mg to 300 mg daily) for variable periods of time. The commonest side effect noted was reddish brown pigmentation of skin in 77.8% patients. In an equal number of patients, ichthyotic changes on the peripheral parts of the body were noticed. GIT symptoms occurred only in 0.04% patients in the form of abdominal pain, epigastric distress, mild transient nausea and anorexia. Other minor side effects noted were reddish coloration of sweat, urine and tears. Schilling's, d-xylose tests and faecal fat excretion were near normal in the 21 patients in whom these parameters were done. No abnormality in the Jejunal mucosal biopsy was observed after therapy. No abnormality in the EKG or serum biochemistry occurred even after prolonged therapy. We found the drug to be very safe in the usual doses.

Abdominal pain is a common gastrointestinal symptom in children. The purpose of this paper is to determine the upper gastrointestinal mucosal pathology in a group of children with abdominal pain. 48 consecutive children referred to the authors with the problem of abdominal pain were studied. These were divided into 2 groups. Those with only one episode of pain and lasting for less than 2 weeks were considered to have acute abdominal pain. Those with repeated episodes of pain and lasting for more than 2 weeks were considered to have recurrent abdominal pain. Careful clinical examination was done to exclude an acute surgical abdomen. Other common causes of abdominal pain in our population such as urinary tract infection, lactose intolerance, hepatitis and choledochal cyst were excluded by clinical examinations and laboratory investigations. Upper gastrointestinal endoscopy was done by one of the authors. Five out of the 16 children with acute abdominal pain had macroscopic features of acute gastritis and another 2 had duodenitis. In the other 32 children with recurrent abdominal pain, 5 had duodenal ulcers and 3 had reflux oesophagitis. It was concluded that upper gastrointestinal endoscopy was a useful means of identifying the upper gastrointestinal pathology in children with abdominal pain. 43% and 25% of the children with acute and recurrent abdominal pain respectively had a cause identified by gastroscopy.

Dientamoeba fragilis is an intestinal protozoan parasite associated with gastrointestinal symptoms. This study was undertaken in a semicommunal group reported to have a high prevalence of this parasite. Stools were collected from 81 adult group members. Intestinal parasites were observed in stool specimens of 45 (56%) of the 81 adults; D. fragilis was found in 33 (41%) subjects. This paper describes the clinical findings and treatment of 26 adults with D. fragilis alone or with a commensal. Gastrointestinal symptoms were observed in 22 (85%) of infected subjects; abdominal pain and excessive flatus were significantly more common in this group. diiohydroxyquin 650 mg three times a day for 20 days eliminated the parasite in 10 (83%) of the 12 treated, although three subjects required a second course of therapy. Parasitic infection should be considered in patients with vague gastrointestinal symptoms, especially those living in endemic areas, in close proximity, or with a history of foreign travel.

One hundred and sixty ex-servicemen who had been prisoners of war in south-east Asia during 1942-5 were investigated for infection with Strongyloides stercoralis. Larvae were found in 44 (27.5%) of the men, who had therefore been infected for 34-37 years. Direct microscopy of the faeces was the most successful diagnostic method, giving a positive result in 37 cases (84%); multiple examinations were often necessary. Faecal culture was positive in 30 cases (68%), but examination of duodenal fluid obtained with the string test gave a positive result in only 17 (39%). The mean blood eosinophil count and mean serum IgE concentration were higher in the infected men, though normal values were often found in individual cases. Clinical manifestations of isolated strongyloides infection were analysed by comparing the infected men with control groups of ex-prisoners in south-east Asia without proved strongyloidiasis and ex-prisoners in Europe. Twenty-nine infected men (66%) complained of non-specific urticaria, and 13 (30%) had pathognomonic larva currens. Gastrointestinal symptoms significantly more common in the infected group were diarrhoea, indigestion, lower abdominal pain, pruritus ani, and weight loss (p <0.05-p <0.0005).The study group was thought to be reasonably representative of Allied ex-servicemen imprisoned in south-east Asia during the second world war. Probably there are many thousands of infected persons in several countries. The worm has an unusual ability to multiply, and larvae may spread throughout the body in immunosuppressed subjects.

There are increasing challenges for the practising gastroenterologist in treating AIDS-related gastrointestinal diseases. The differential diagnoses of dysphagia and odynophagia include cytomegalovirus (CMV) and herpes simplex virus (HSV) infection, non-specific aphthous ulceration and non-AIDS oesophageal diseases, especially reflux oesophagitis. Chronic subacute abdominal pain with nausea, vomiting, early satiety and weight loss is suggestive of an obstructive lesion caused by lymphoma or Kaposi's sarcoma. Severe acute abdominal pain can indicate pancreatitis or intestinal perforation due to cytomegalovirus. Right upper quadrant pain (with or without fever, vomiting or abnormal liver function tests with a cholestatic profile) is suggestive of hepatobiliary pathology including cholecystitis, cholangitis, acalculous cholecystitis and AIDS cholangiopathy. Diarrhoea is the most common gastrointestinal symptom of AIDS, affecting 50-90% of patients. Causes of AIDS diarrhoea include protozoa (Cryptosporidium parvum, Isospora belli, Enterocytozoon bieneusi, Septata intestinalis, Cyclospora spp, Entamoeba histolytica and Giardia lamblia), bacteria (Mycobacterium avium-intracellulare, Clostridium difficile, Salmonella, Shigella and Campylobacter jejuni), and viruses (CMV, HSV and possibly HIV). Chronic diarrhoea, malnutrition and weight loss can shorten the life-span of patients with AIDS. Elemental diets, isotonic formulas, medium chain triglycerides and total parenteral nutrition have been tried with little success in AIDS patients with severe diarrhoea and wasting.

Gastrointestinal symptoms attributable to Toxoplasma gondii infection are distinctly unusual, and antemortem diagnosis of gastrointestinal involvement is rarely documented, particularly in the absence of cerebral manifestations or disseminated disease. This case report describes a rare example of T. gondii infection of the stomach diagnosed antemortem in a 22-year-old Haitian woman with acquired immunodeficiency syndrome (AIDS) who presented with fever and abdominal pain. An abdominal computerized tomographic scan showed thickened gastric walls. Endoscopy showed diffusely thickened gastric folds and a fundic ulcer along the greater curvature. Light and electron-microscopic examination of gastric mucosal biopsy specimens showed active Toxoplasma infection with necrosis and intracellular trophozoites within the gastric epithelium, smooth muscle cells, macrophages, and endothelial cells. Both true cysts and pseudocysts were seen. Disseminated disease was documented by the growth of T. gondii in a tissue culture from a venous blood sample. It is concluded that some patients with AIDS, particularly those from areas endemic for Toxoplasma infection, can manifest disseminated disease in unusual locations such as the gastrointestinal tract. Documentation of active T. gondii infection based on tissue cultures of venous blood or on biopsy specimens of symptomatic extracerebral sites can lead to a rapid diagnosis of toxoplasmosis, a treatable disease.
