The effect of the topical steroid clobetasone butyrate on coeliac mucosa maintained in organ culture.

The effect of the topical corticosteroid clobetasone butyrate on enzyme activity and morphology of duodenal mucosa was studied in 9 patients with coeliac disease and 10 controls using organ culture techniques. There was significant increase in mucosal alkaline phosphatase, lactase and maltase activities, but inclusion of a soluble extract of gluten reduced this effect. When clobetasone butyrate was also included in the culture medium significant elevations in enzymes were again observed. Enterocyte height was not affected by incorporation of gluten into the medium. Intra-epithelial lymphocyte counts fell significantly during the culture period. This improvement was also inhibited by gluten and overcome by addition of steroid.

Clinical, biochemical and morphological responses of patients with villous atrophy to oral betamethasone valerate and clobetasone butyrate.

10 patients with sub-total villous atrophy were given the topical corticosteroids betamethasone valerate or clobetasone butyrate for a period of 4 months whilst continuing on a normal diet. 5 patients improved symptomatically while red cell folate, urinary xylose and faecal fat excretion also improved. Brush border enzymes increased in patients treated with higher dosages of each drug. Enterocyte height increased and intra-epithelial lymphocytes were significantly decreased although overall morphological appearances remained indistinguishable from untreated coeliac disease. Suppression of the pituitary adrenal axis occurred in 8 patients and there did not appear to be useful separation of topical from systemic activity. These compounds offer no advantage over prednisolone in non-responsive coeliac disease.

Evidence for a change in neurotransmitter affecting oesophageal motility in Parkinson's disease.

In a study of oesophageal motility in 20 patients with Parkinson's disease, intravenous atropine produced marked disruption of co-ordination in response to swallows, when compared with control subjects. This suggests that cholinergic rather than dopaminergic mechanisms are more important in the control of swallowing in patients with Parkinsonism. No conclusive evidence of peripheral dopamine depletion or autonomic neuropathy was found, although minor changes suggestive of the former were found in severely affected patients.

Drug-induced gastrointestinal disease.

Clinicians administering potent therapeutic agents must be aware of their side-effects. The gut is an important site of adverse drug reactions and drug-induced disease must always be considered in the differential diagnosis of patients presenting with gastrointestinal symptoms. A careful drug history must therefore be taken in all such patients. Symptoms can often be related to drug ingestion, but late effects also occur. The presence of blood in vomitus or stool is pathognomonic of serious pathology which may be drug-induced and requires further investigation. Upper gastrointestinal haemorrhage and pseudomembranous colitis are potentially fatal manifestations of drug therapy. Gastrointestinal symptoms can often be avoided if therapy is taken with meals or in a smaller dose, but drug withdrawal is always the first line of management in patients whose symptoms may be drug-induced.

Is there excessive use of gastric lavage in the treatment of self-poisoning?

An attempt to identify those factors which influenced the decision to perform gastric lavage in 236 cases of deliberate self-poisoning seen over 6 months showed that 87% of patients seen within 4 hours of ingestion of the poison had a lavage, irrespective of the number of tablets and nature of drug taken. Overall, 77% had a gastric lavage. Most of the late lavages were carried out for salicylate ingestion. The changing pattern of drugs used for attempted selfpoisoning suggests that at least 50% of patients are being unnecessarily subjected to gastric lavage.

The use of long-term acid-suppression therapy.

Drug therapy to suppress gastric acid secretion is commonly used in the management of dyspepsia, many patients taking such therapy over long periods of time. An audit of patients on long-term (> 12 months) acid-suppression therapy was carried out in the two practices providing primary healthcare to a town in Northeast England. Patients on continuous therapy (> 10 months' supply in the previous year) and intermittent therapy (6-10 months' supply in the previous year) were identified through computerised prescribing records. Their written and computer records were scrutinised to determine diagnosis, duration of therapy, use of NSAIDs and other features. A total of 365 patients were identified (208 men, 157 women): 132 were on intermittent and 233 on continuous therapy. Of the total, 83% were over 45 years and one-fifth were taking NSAIDs. Of the 310 patients investigated for their dyspepsia, only 250 had a positive diagnosis, of which duodenal ulcer (154) was the most common.

Information for patients about inflammatory bowel disease.

In inflammatory bowel disease it is important that patients understand their condition since this helps to improve long-term management of the disease. The aim of this study was to assess the information given to patients with inflammatory bowel disease about their condition, its treatment and the National Association for Colitis and Crohn's disease. Two surveys were performed, using anonymous questionnaires. One was of all association members in north-east England, the other was a sample of patients attending medical outpatients. The surveys showed that more patients heard of the National Association for Colitis and Crohn's disease from the media than from medical sources. Of patients seen in medical clinics, 75% would welcome more information about their disease. In four of the six participating centres less than half the patients had been told about the existence of a patients' association. There was considerable variation in the instructions on what action to take in the event of a relapse. These findings suggest that the opportunity offered by out-patient clinics to educate and inform patients is often wasted. Clinicians often neglect to mention the National Association for Colitis and Crohn's disease, especially to patients with long-standing disease. A higher priority should be given to providing patients with appropriate information on inflammatory bowel disease. Three simple audit standards for the organisation of outpatient clinic information are proposed.
