- OBJECTIVES: The objective of this study was to assess the relationship between inflammation, endothelial activation and incipient atherosclerosis in type 2 diabetes. DESIGN: Cross-sectional study. Setting and subjects. We studied 239 type 2 diabetic patients [71 with clinical cardiovascular disease (CVD)] and 78 healthy control subjects, aged 50-75 in a single research centre. METHODS: Carotid intima-media thickness (IMT) was determined by ultrasound. Circulating intracellular adhesion molecule-1, vascular cell adhesion molecule-1, E-selectin, ultra-sensitive C-reactive protein, human serum amyloid A, interleukin-6, monocyte colony-stimulating factor, secretory nonpancreatic phospholipase A(2) type IIA, glucose, HbA1c, and lipid/lipoprotein variables were measured. RESULTS: Carotid IMT was significantly thicker in diabetic patients than healthy controls across the whole age range. IMT was also thicker in diabetic patients with, than without, CVD, but this difference disappeared after controlling for confounding factors. Concentrations of the inflammatory and endothelial markers except IL-6 were significantly higher in the diabetic patients than in healthy controls, but comparable in diabetic patients with and without CVD. The main determinants of IMT in the diabetic patients were blood pressure, age and diabetes duration. CONCLUSIONS: Low-grade inflammation and endothelial activation are increased in diabetic patients but do not associate with IMT or clinical CVD. The inflammatory reaction seems to be rather a feature of the metabolic syndrome than a direct determinant of atherosclerosis.

- Rectal and anal motility responses to pharmacological manipulation of neuro-transmission and graded efferent electrical pelvic nerve stimulation were investigated in alpha-1-chloralose anaesthetized cats. N omega-nitro-L-arginine (L-NNA), a competitive inhibitor of nitric oxide synthase, did not influence spontaneous rectal and anal motility. No significant change in anal pressure or rectal tone was observed after sectioning the pelvic nerves in animals pretreated with L-NNA. The effect of pelvic nerve stimulation on anal tone was varying and depended upon the intensity of stimulation and the prevailing anal tone. A reduction of anal tone on pelvic nerve stimulation was consistently converted to an increase of anal tone after pretreatment with L-NNA. The rectal response to pelvic nerve stimulation was unchanged by L-NNA. Residual increase of anal tone observed on pelvic nerve stimulation after L-NNA and noradrenergic blockade was partly sensitive to hexamethonium and abolished by atropine. The results suggest that there is no tonic influence on rectal and anal motility via nitric oxide mechanisms. On the other hand, the reduction of anal tone on high intensity pelvic nerve stimulation seemed to be dependent on the release of nitric oxide. An excitatory cholinergic component of the smooth muscle contractility of the feline anal canal, partly sensitive to hexamethonium, was demonstrated to be conveyed in the pelvic nerves.

- Formation of an ileo-anal pouch is an accepted technique following colectomy in the surgical management of ulcerative colitis (UC) and familial adenomatous polyposis (FAP). The configuration of pouches and anastomotic techniques has varied over the last two decades. The increased use of stapling devices in formation of the pouch-anal anastomosis avoids the need for endoanal mucosal stripping and may contribute to improved functional results, but leaves a 'columnar cuff' of residual rectal mucosa in situ. Concerns regarding the long-term safety of the ileo-anal pouch have been raised by reports of the occurrence of dysplasia in the pouch mucosa and 15 cases of adenocarcinoma. In UC, persistence of underlying disease in the residual rectal mucosa, anal transition zone and columnar cuff provides the site for development of dysplasia and malignancy. Pouchitis is unlikely to be a major cause of dysplasia or malignancy, as long-term follow-up of patients with Koch pouches has demonstrated. In FAP, any persistent rectal mucosa and mucosa of the small intestine is at risk of adenomatous dysplasia due to the genetic alterations causing the disease. Long-term surveillance should focus on all FAP pouch patients, and in UC patients should be directed towards the diagnosis of residual rectal mucosa in the area distal to the pouch anastomosis. Specialist histopathological opinion is essential in the diagnosis of dysplasia in the ileo-anal pouch.

Evidence of poor vitamin status in coeliac patients on a gluten-free diet for 10 years

- Background: Patients with coeliac disease are advised to keep to a lifelong gluten-free diet to remain well. Uncertainty still exists as to whether this gives a nutritionally balanced diet. Aim: To assess the vitamin nutrition status of a series of coeliac patients living on a gluten-free diet for 10 years. Methods: Thirty adults with coeliac disease (mean age, 55 years, range, 45-64 years, 60% women), in biopsy-proven remission following 8-12 years of dietary treatment, were studied. We measured the total plasma homocysteine level, a metabolic marker of folate, vitamin B-6 and vitamin B-12 deficiency, and related plasma vitamin levels. The daily vitamin intake level was assessed using a 4-day food record. Normative data were obtained from the general population of the same age. Results: Coeliac patients showed a higher total plasma homocysteine level than the general population, indicative of a poor vitamin status. In accordance, the plasma levels of folate and pyridoxal 5'-phosphate (active form of vitamin B-6) were low in 37% and 20%, respectively, and accounted for 33% of the variation of the total plasma homocysteine level (P < 0.008). The mean daily intakes of folate and vitamin B-12, but not of vitamin B-6, were significantly lower in coeliac patients than in controls. Conclusions: Half of the adult coeliac patients carefully treated with a gluten-free diet for several years showed signs of a poor vitamin status. This may have clinical implications considering the linkage between vitamin deficiency, elevated total plasma homocysteine levels and cardiovascular disease. The results may suggest that, when following up adults with coeliac disease, the vitamin status should be reviewed.

Adverse reactions to intravenous administration of fusidic acid.

- To study adverse reactions associated with intravenous administration of fusidic acid 6 patients were treated with fusidic acid intravenously in association with a major large bowl operation, and 9 patients were treated in the same way because of staphylococcal infections. The main adverse reaction was thrombophlebitis, which occurred in as many as 12 of 14 patients who were treated for 2 days or longer. Three surgical patients developed postoperative hyperbilirubinaemia, but studies of liver function before and during treatment in 6 of the patients with staphylococcal disease revealed no adverse liver reactions. Intravenous administration of fusidic acid into a peripheral vein for 24 h or more involves an extremely high risk of developing thrombophlebitis.
