A flexible loading dose schedule for warfarin therapy.

A flexible loading dose schedule for inducing anticoagulation with warfarin was assessed in 31 consecutive patients. 55% reached the therapeutic range (prothrombin ratio between 2 and 4:1) by Day 2 (40 hours after the first dose) and this figure rose to 77% on Day 3 and to 87% on Day 4. All patients had a PTR between 1.7 and 4.2 on Day 5. Patients with evidence of cardiac failure and abnormal liver function, and those taking medications known to interact with warfarin required lower doses and ran a higher PTR when compared with the total group of patients. This schedule offers a useful means of safely and rapidly inducing warfarin therapy in all patients.

Retrospective investigation of transfusion-related non-A, non-B viral hepatitis associated with M2 antigen.

A retrospective study of transfusion-related non-A, non-B viral hepatitis was conducted in seven patients. Findings showed that six recipients had been exposed to at least one unit of blood possessing a putative serological marker for non-A, non-B hepatitis, the M2 antigen or anti-M2IgM. The M2 markers were associated with non-A, non-B hepatitis that developed 3-7 weeks after transfusion. It sees increasingly probable that M2 markers may be useful for diagnosis and/or prevention of post-transfusion hepatitis.

Delay in diagnosis of adult coeliac disease.

The delay in diagnosis of 106 patients with adult coeliac disease, diagnosed between 1976 and 1980, was studied. Overall, delay in diagnosis was 11 +/- 10.6 years, being considerably greater in females (12.8 +/- 7.8 years) than in males (3.5 +/- 9.8 years). Most of this delay occurred prior to hospital referral, although that following referral to hospital clinics was still significant (1.8 +/- 4.8 years). The most common presenting complaints were lassitude (75%) anaemia (65%) and flatulence (50%). Typical gastro-intestinal symptoms were relatively uncommon and mild, but when present led to a more speedy diagnosis. It is concluded that, despite advances in modern diagnostic procedures, little progress has been made in hastening the diagnosis of coeliac disease.

Comparative viabilities of rat intestinal epithelial cells prepared by mechanical, enzymatic and chelating methods.

Mechanical, enzymatic and chelating methods for isolating rat intestinal epithelial cells were compared to determine the best technique for obtaining high yields of viable cells. The mechanical techniques resulted in consistently poor viability compared with the other methods. There was excellent agreement between viability determinations made by trypan blue exclusion and by cytofluorochromasia. Incubation with EDTA, citrate and dithiothreitol, combined with mechanical extrusion of dissociated cells provided the highest yields of viable cells in these studies.

Hepatic necrosis in rats following halothane administration: protective effect of diethyldithiocarbamate.

Foci of necrosis have been observed in the liver of 50% of enzyme-induced rats treated with halothane. The frequency of liver necrosis was significantly reduced by treatment with the free radical scavenger diethyldithiocarbamate. The severity of the lesion was not increased by repeated exposures to the anesthetic, and, although the frequency of liver necroses may be greater, the differences were not statistically significant.

Pulmonary function in patients with inflammatory bowel disease.

Pulmonary function has been assessed in 36 outpatients with inflammatory bowel disease. The carbon monoxide transfer factor was found to be significantly reduced in patients as compared with matched controls (P less than 0.01). The reason for this reduction is not clear but it is unlikely to be due to sulfasalazine (Salazosulphapyridine).

Serum lysozyme levels in malignant histiocytosis of the intestine.

Serum lysozyme levels were significantly raised in a group of eight patients with malabsorption associated with gastrointestinal lymphomas of a type recently characterised as malignant histiocytosis of the intestine. In four of the cases, levels were markedly raised. In contrast there was no significant difference between groups of patients with uncomplicated adult coeliac disease and healthy controls. The estimation of serum lysozyme is a simple test to perform and may be valuable in the diagnosis of malignant histiocytosis of the intestine, in particular differentiating it from uncomplicated adult coeliac disease.

Endoscopic duodenal biopsies in coeliac disease and duodenitis.

Endoscopic duodenal biopsies were taken from 27 patients with suspected coeliac disease and compared with intubation capsule jejunal biopsies. The specimens were reported without knowledge of the patients' names or symptoms. In 24 patients (89%), coeliac disease could either be diagnosed or excluded with 100% accuracy, despite the inability to orientate the biopsies correctly. Six biopsies were considered technically unsatisfactory, but only in three (11%) was it impossible to exclude coeliac disease. Duodenal biopsies were also taken from 118 consecutive patients attending for routine upper gastrointestinal endoscopy, and 1 patient with coeliac disease was discovered. We conclude that endoscopic duodenal biopsies are a reliable and worthwhile screening test for coeliac disease in certain patients attending for routine upper gastrointestinal endoscopy.

Immunofluorescent antibodies in patients with bird-fancier's lung.

To assess its value as a screen for avian antibodies, indirect immunofluorescence against avian intestinal tissue has been to test sera from thirty-nine patients with documented bird-fancier's lung disease, thirty-eight asymptomatic bird-fanciers and 257 controls without known avian contact. Immunofluorescent antibodies occurred more frequently than precipitins among patients with BFL and asymptomatic bird-fanicers. Globular fluorescence within the mucus occurred only in patients with avian contact, although other fluorescent antibodies were seen with control patients. No particular pattern was confined to patients with the lung disease. When included in an autoantibody profile, indirect immunofluorescence provides a sensitive and convenient alternative to precipitin methods in screening for avian antibodies.

IgA and IgG reticulin antibodies in coeliac and non-coeliac patients.

Using indirect immunofluorescence, comparisons were made of patterns of staining of five tissue substrates with 28 RI reticulin antibody-positive coeliac sera, and 23 RI reticulin antibody-positive non-coeliac sera. IgA and IgG fluorescein conjugates were used separately. IgA antibodies were seen in 22 coeliac patients (78%) compared with three non-coeliacs (13%). Concomitant sinusoidal fluorescence (RS pattern) was seen more frequently with the non-coeliac (60.9%) than with the coeliac sera (10.7%). Such differences may help to distinguish those patients who should have a jejunal biopsy when using the reticulin antibody as a screening test for coeliac disease.

Ratio of urinary 6beta-hydroxycortisol to 17-hydroxycorticosteroids in patients with liver disease.

The ratio of 6beta-hydroxycortisol to 17-hydroxycorticosteroids in the urine of 73 patients with liver disease, and 53 controls has been measured. The mean ratio was significantly greater in the liver disease group (p less than 0.001), this elevation being most marked among patients with liver metastases and patients with acute hepatitis. We feel that the use of the ratio as a test of early liver cell dysfunction requires further evaluation, in particular in the early recognition of metastatic liver disease.
