Of 18 patients with small-intestinal lymphoma associated with villous atrophy and crypt hyperplasia of uninvolved mucosa, most presented with acute obstruction or perforation preceded by abdominal pain and weight-loss. Malabsorption, thought to be adult coeliac disease, preceded the diagnosis of lymphoma in 5 cases. The lymphomas were composed of malignant histiocytes and were classified on morphological grounds as malignant histiocytosis. Of particular interest was the finding by immunohistochemical techniques of all major immunoglobulin classes within malignant cells of single tumors. Characterisation of this group of lymphomas as a specific entity should help in the further understanding of the relationship of malabsorption and lymphoma and in the rationalisation of treatment.

A case of Whipple's disease in a female is described. Malabsorption of iron, vitamin B12, folic acid and fat was present. These abnormalities reverted to normal after introduction of co-trimoxazole therapy. The patient's humoral immune system was normal, in contrast to impairment of cell-mediated immunity, which has not improved in spite of co-trimoxazole treatment for 2 years, and a therapeutic trial of levamisole. These findings are further evidence that there may be a primary immune deficiency in patients with Whipple's disease.

A case report is given of a patient with a malabsorption syndrome. Primary diagnostic procedures including x-ray examinations and endoscopy yielded no results. Alterations of the abdominal lymph vessel system were found during peritoneoscopy giving rise to the hypothetical diagnosis of Whipple's disease. This diagnosis was confirmed by intestinal biopsy yielding macrophages with PAS-positive inclusion bodies. It is pointed out, that peritoneoscopy is a good means to evaluate the abdominal lymph vessel system.

A 57 year old male had recurrent arthritis and uveitis for 34 years, spinal symptoms for 10 years, and malabsorption for four months leading to the diagnosis of ankylosing spondylitis and Whipple's disease. HLA-B27 was positive. Out of the four cases of Whipple's and ankylosing spondylitis in the literature, only one had been tested for HLA-B27 and was found to be negative.

The effect of an alpha-glucosidehydrolase inhibitor (alpha-G.H.I.) on intestinal absorption of sucrose was assessed by measuring rises in blood-glucose and intestinal hydrogen production after ingestion of 100 g sucrose. 200 mg alpha-G.H.I. given with the sucrose completely inhibited early postprandial blood-glucose rises, prevented late postprandial dips in blood-glucose, and considerably increased breath-hydrogen levels, which indicates sucrose malabsorption. Thus the inhibitor can be used to study carbohydrate malabsorption and may be useful as a method for retarding carbohydrate absorption.

Plasma concentrations of vitamin D-binding globulin were measured by radial immunodiffusion in healthy subjects, pregnancy, and during oestrogen therapy. Subjects with disorders of vitamin D metabolism (dietary deficiency, malabsorption, anticonvulsant therapy, chronic liver disease) were also studied. Neither sex nor age influenced the plasma vitamin D-binding globulin concentration in healthy subjects, but there was a significant increase in concentration during pregnancy and oestrogen therapy. Elevated levels were found in vitamin D deficient elderly but not younger subjects, while levels in subjects with chronic liver disease were significantly reduced. Normal levels of vitamin D-binding globulin were present in hypervitaminosis D and no vitamin D-binding globulin was detected in human milk. No correlation was observed between plasma 25-hydroxycholecalciferol levels and plasma vitamin D-binding globulin concentrations.

Non-specific ileojejunitis, characterised by mild to moderate structural changes in the intestinal mucosa and often associated with asymptomatic malabsorption, is known to occur in the tropics and in countries with hot climates. This acquired condition is probably related to environmental factors, and some consider it to be a subclinical form of tropical sprue. Changes in the intestinal mucosa typical of non-specific ileojejunitis were found in 10 indigenous Indians as well as 5 people of Latin stock living in the Southern Peruvian sierra, where tropical sprue has not as yet been demonstrated and which has a temperate climate.

This study was to determine if orally administered duodenal fluid, as a source of intestinal microorganisms, would influence absorption of gamma-globulin of colostrum in newborn calves. Duodenal fluid was obtained 2 h postfeeding from a cannulated milk-fed calf. Twenty-seven male and female Holstein calves obtained within 6 h of birth were assigned randomly to one of three treatments: 1) colostrum alone, 2) 200 ml duodenal fluid immediately followed by colostrum, and 3) 200 ml duodenal fluid followed 3 h later by colostrum. Pooled colostrum was fed at 10% of body weight in two daily feedings. Total protein, albumin, alpha-globulin, beta-globulin, and gamma-globulin of blood serum were determined prior to colostrum consumption, and again 24 and 48 h after administration of duodenal fluid. Total proteins, beta-globulin, and gamma-globulin of serum increased with age in all calves. Inocula interference with absorption was indicated by depressed values of serum in calves of treatment 3 as compared to treatment 1 calves for protein (5.28 to 6.28 g/dl), beta-globulin (.67 to .87 g/dl), and gamma-globulin (.76 to 1.33 g/dl). Protein was also lower in calves of treatment 3 (6.05 g/dl) compared to uninoculated calves (6.28 g/dl). Malabsorption of colostral proteins may be related to early establishment of large numbers of intestinal microorganisms in the newborn calf.

Small bowel biopsy is a routine procedure used mainly in the evaluation of malabsorption. The Crosby-Kugler capsule, which permits the performance of just one biopsy per session and hydraulic biopsy tubes, permitting multiple biopsies from any level of the small bowel, have been in use now with several modifications for about 20 years. The diagnostic range and risks of these tools are described briefly in this paper and discussed in the light of our own experience in 80 patients. In accordance with the experience of others, we found that small bowel biopsy was accompanied by only a few minor complications and we consider it a valuable procedure in clinical diagnosis and experimental research.

Symptoms associated with carbohydrate malabsorption limit the usefulness to diabetics of a powerful glycoside-hydrolase inhibitor (acarbose) which reduces postprandial glycaemia. Addition of a low dose (50 mg) of a acarbose together with 14.5 g guar gum to a breakfast test meal taken by 8 healthy volunteers reduced the mean peak rise in blood-glucose at 30 min by 70%. Areas under the insulin and gastrointestinal-polypeptide response curves were also greatly reduced. No evidence of carbohydrate malabsorption, as assessed by measurement of breath hydrogen, was found during any of the test periods. When acarbose was taken alone, 3 of the 8 subjects had troublesome symptoms and the 30 min rise in blood-glucose was reduced by only 28%. Thus, combination of these two agents effectively reduces the rate of carbohydrate absorption without increasing side-effects and may make combined acarbose and guar acceptable in the management of some diabetics.
