Diarrhea is a common gastrointestinal problem in diabetes, and its prevalence has been underestimated. The cause of diabetic diarrhea is unknown, but it is probably related to gastrointestinal motility disturbances secondary to diabetic autonomic neuropathy. Other causes (especially primary malabsorption syndromes and islet cell tumors) must be excluded. Treatment of diabetic diarrhea is largely symptomatic and only moderately effective. Antidiarrheal agents may ameliorate acute episodes. Broad-spectrum antibiotics and clonidine hydrochloride (Catapres) have had some success in long-term control. Most recently, subcutaneous administration of somatostatin analogues has been shown to be helpful, the main side effects being drowsiness and vomiting.

The hazards of pregnancy for both the mother and the fetus in diabetic women with severe retinopathy and nephropathy are well reported. We wish to highlight a poorly recognized problem in the obstetric management of the diabetic mother, that of pregnancy in a patient with autonomic neuropathy. Two such cases are reported where the presence of autonomic neuropathy severely jeopardized the health of the mother, with the loss of the fetus in one, due to occurrence of severe and intractable vomiting. The presence of moderate to severe symptomatic diabetic autonomic neuropathy, particularly with evidence of gastroparesis, may be a relative contraindication to pregnancy.

Gastroparesis after a viral infection has rarely been reported. In this article, we describe the clinical features and long-term outcome of 7 patients who had gastroparesis after a presumed viral illness and who were identified in a retrospective review of 103 consecutive cases of gastroparesis seen at our institution from 1977 through 1988. The three male and four female patients with gastroparesis after a suspected viral illness were young (mean age, 26.9 years) and healthy before the onset of the illness, which manifested as low-grade fever, fatigue, and myalgia with or without diarrhea. A mean of 4.5 days after spontaneous resolution of the viral illness, persistent nausea, vomiting, and epigastric pain developed in these patients. In all seven patients, delayed emptying of the gastric contents was substantiated. Autonomic neuropathy was found in all three patients who underwent autonomic function tests. During a mean follow-up of 32.3 months, five of the seven patients had complete resolution of gastroparetic symptoms, and the other two had considerable improvement of their condition. We conclude that postviral gastroparesis is uncommon, is frequently associated with autonomic dysfunction, and is associated with an apparently excellent prognosis.

A 27 year old male with metastatic testicular carcinoma was treated with cisplatin, vinblastine, and bleomycin (PVB) chemotherapy. After receiving a cumulative dose of 500 mg/m2 of cisplatin, he developed severe nausea and vomiting and had clinical evidence of a cisplatin-induced peripheral neuropathy. His vomiting resolved five weeks after discontinuation of cisplatin. We believe this case represents the first report of gastric autonomic neuropathy induced by cisplatin.

Changes in impedance across the epigastrium form the basis of a new non-invasive method of assessing gastric emptying of liquids. The apparatus is simple to use at the bedside and, in conjunction with conventional investigations, is of value in diagnosing gastroparesis in patients with diabetic autonomic neuropathy and symptoms of recurrent vomiting. We measured gastric emptying of liquids in 22 diabetics aged 33.4 +/- 9 years (mean +/- SD) with severe symptomatic autonomic neuropathy (mean heart rate variability 4.9 +/- 2.2 SD beats/min), and 15 normal controls. Median 'half emptying' time in the diabetics with autonomic neuropathy was prolonged overall but it was not always abnormal (12.25 min, range 6.5-greater than 30 compared to 8.0 min, range 3-17; p less than 0.01). Results in five diabetics with symptoms of recurrent vomiting corresponded with those using conventional radiological methods, confirming gastroparesis in three instances and excluding it in two. The effect of metoclopramide was also studied and was shown to accelerate gastric emptying in some but not all of the patients. Assessment of gastric emptying using the impedance method assists in establishing the diagnosis of gastroparesis and is of value for repeated measurements.

Gastrointestinal symptoms such as vomiting, constipation, diarrhea, and fecal incontinence occur frequently in patients with diabetes mellitus. In a survey of 136 diabetic outpatients, 76% had one or more gastrointestinal symptoms, the commonest symptom being constipation (found in 60%). In many cases these symptoms are thought to be due to abnormal gastrointestinal motility that, in turn, may be a manifestation of diabetic autonomic neuropathy involving the gastrointestinal tract. The pathophysiology of these gastrointestinal symptoms, clarified in recent studies, and the clinical features and treatment of these problems in diabetic patients are reviewed.

Two cases with intractable vomiting due to gastroparesis, a rare feature of diabetic autonomic neuropathy, are described. Both required surgical treatment. In the first a gastroenterostomy was complicated by reflux gastritis requiring a revision operation; in the second a gastrojejunostomy was successful. Electron microscopic studies of the vagus nerve in one of the cases showed a severe reduction in the density of unmyelinated axons, the surviving axons tending to be of small calibre. The severity of the abnormalities supports the view that diabetic gastroparesis is related to vagal denervation.

A 50-year-old diabetic woman experiencing 20 episodes of vomiting each day was admitted to the hospital. When vigorous medical management failed to control the vomiting, psychiatric consultation indicated that psychological factors, especially displaced anger and an early childhood history of gastrointestinal sensitivity, combined with autonomic neuropathy and uremia to produce the symptom. A multimodal treatment regimen including continued medical management, supportive psychotherapy, relaxation training and mental imagery exercises effected a dramatic improvement.

A young, diabetic woman suffering from fainting spells, vomiting, and diarrhea is described. Extensive investigations showed total cardiac denervation, orthostatic hypotension, and disturbances in the the pupillary and sudomotor functions, as well as impairment of glucagon secretion during hypoglycemia. These disturbances were found to be caused by autonomic neuropathy. No signs of peripheral neuropathy could be detected. To the best of our knowledge this is the second case of total cardiac denervation due to diabetic neuropathy described in the literature.

About one-half of patients with insulin- or non-insulin-dependent diabetes have delayed gastric emptying (diabetic gastroparesis). Some of them complain of epigastric pain, nausea, vomiting or postprandial fullness (diabetic dyspepsia), although only a minority are severely symptomatic. Diabetic gastroparesis is clinically relevant not only by virtue of the symptoms induced but also because it may contribute to inadequate glycaemic control and impaired absorption of orally administered drugs. Recent data suggest that abnormal blood glucose control, not only autonomic neuropathy, contribute to the pathogenesis of disordered gastric motility. In most cases diabetic gastroparesis is diagnosed clinically in the absence of demonstrable lesions of the upper gastrointestinal tract. To evaluate gastric emptying, scintigraphy is the 'gold standard'. Gastrokinetic drugs are of help in the treatment of gastroparesis: erythromycin is the first choice in acute presentations and cisapride for chronic symptoms. New macrolides with prokinetic action and devoid of antibacterial properties are very promising and should add another pharmacologic approach to control dyspepsia and gastroparesis in diabetic patients in the future.
