In a consecutive study of 216 outpatients with chronic inflammatory bowel diseases (CIBD) low serum and erythrocyte folate levels were found in 59% and 26%, respectively. In patients with low folate levels in both serum and erythrocytes, megaloblastic changes in the bone marrow ere found in 67% (29 out of 44). Their folate intakes were borderline. Absorption studies with tritiated folate showed low absorption values on repeated examinations in 23% of the patients with low folate values (9 out of 40), with no relationship to the intake of salazosulphapyridine. In patients with low folate values the reticulocyte count was elevated (related to the dose of salazosulphapyridine), and the 51Cr erythrocyte survival was decreased. It is suggested that folate deficiency in CIBD is of multiple origin: inadequate diet, malabsorption, and chronic drug-induced low-grade haemolysis. The clinical consequence of the findings remains to be evaluated.

Patients with cystic fibrosis (C.F.) showed raised serum levels of alpha-fetoprotein (AFP). A moderate but significant increase in serum AFP was present in their parents and some siblings. There was no correlation between the clinical severity of the disease and serum AFP concentration. Samples from control groups with gluten-induced malabsorption and bronchiectasis had normal levels. Persistent synthesis of AFP may be an associated marker of C.F. genes, and estimation of serum AFP might help in detecting heterozygote carriers in families at risk.

Phosphorylcholine and homocysteine have an important choleretic action and also potentiate exocrine pancreatic secretion by way of stimulation and a more effective preparation of the substrate against attack by lipolytic enzymes. The protection offered by pancreatic enzymes in the correction of the digestive insufficiency in the endoluminal stage is also known. An analysis was therefore made of the action of an association of phosphorylcholine homocysteine and digestive enzymes in cases of exocrine pancreatic insufficiency and primary or secondary malabsorption. This action was evaluated on the basis of the reduction of elimination of steatorrhoea. For this purpose, faecal lipids were determined with the method proposed by van de Kramer et al. The most significant results were obtained in cases where digestive insufficiency was most marked, where correction of the pancreatic enzyme deficiency and improved biliary function were particularly required.

Multiple immunological abnormalities have been demonstrated in fourteen patients with evidence in the blood-film of hyposplenism due to splenic atrophy. Reduction in spleen size was confirmed radiologically, and impairment of phagocytosis by the spleen was demonstrated by studying the survival and fate of chemically damaged autologous red blood-cells. Eight of the patients had intestinal malabsorption, and there was a high frequency of autoimmune disease in the remainder. Although patients with splenic atrophy showed little evidence of impairment of normal immune responses, there was a high frequency of autoantibody formation. There is thus an association between widespread immunological disturbances, notably autoimmunity, and splenic atrophy.

2 patients, who were treated with clioquinol after radical resection of carcinoma of the rectum and colostomy, developed symmetrical sensorimotor polyneuropathy, mild posterior tract ataxia, bilateral pyramidal tract lesions and optic neuropathy, a clinical picture compatible with subacute myelo-optic-neuropathy (S.M.O.N.). One patient had neurological symptoms after having received 750 g of clioquinol, 3 years after treatment started, and impairment of vision was noted after having received 1200 g. The other patient had neurological symptoms 6 weeks after clioquinol was first given, having received 65 g, the average daily dose being 1.5 g, and vision was impaired after 765 g had been administered. On examination 12 and 14 months after clioquinol had been discontinued, the first patient's vision was slightly improved, but he was otherwise unchanged, while the vision of the other patient was unchanged, but she had otherwise deteriorated slightly neurologically. Electrophysiological examinations confirmed the clinical observations. A multifactor etiology of the syndrome: neurotoxicity of clioquinol, paraneoplastic neuropathy and malabsorption, is discussed.

The suitability of the simultaneous azocoupling reaction with 1-naphthyl-beta-D-glucoside and hexazonium-p-rosanilin in the detection of the activity of lactase (or lactase-beta-glucosidase complex) in jejunal biopsies of patients with various forms of the malabsorption syndrome was tested. Results were compared with those obtained with the indigogenic method using 4-Cl-5-Br-3-indolyl-beta-D-fucoside which is the method of choice. Both methods gave identical results as far as the relative intensity of the brush border staining was concerned. The azocoupling method applied in unfixed cold microtome sections can be recommended for the routine diagnostics of the malabsorption syndrome when the indolyl substrate is not available.

Chromatographically separated fractions of a proteolytic digest of wheat gliadin were assayed for cytotoxic properties using cultured human embryonic intestinal, lung, kidney, adrenal, and HEp-2 cells. In all cell types noxious effects were observed microscopically over a 24 h period. The most active fraction was that previously shown to produce xylose malabsorption in subjects with coeliac disease, disruption of lysosomes, and inhibition of morphological recovery of cultured mucosa from a patient on a gluten-free diet.

The cause of death was obtained for 77 members of the Coeliac Society resident in England and Wales. Proportional mortality analysis revealed a significant deficiency in deaths from ischaemic heart-disease in males and a non-significant deficiency in females. It is suggested that this apparent protective effect of coeliac disease might result from malabsorption of dietary lipids. The study also confirmed findings of an excess of deaths from lymphoma and upper gastrointestinal neoplasms.

Three cases of hypogammaglobulinemia are described. In all cases the first symptoms of disease manifesting as pneumonia were preceded by diarrhea. In gastric biopsy there was atrophic gastritis with lack of plasmocytes. All patients demonstrated gastric achylia and symptoms of malabsorption syndrome. The causes of gastrointestinal changes, most probably infections, with simultaneous defective mucosal barrier are discussed.

Diffuse deposition of ceroid pigment in the muscularis propria of the gastrointestinal tract in a patient with a long history of malabsorption of unknown origin is reported. The depostion of this waste pigment is not reversible and is related to prolonged depletion of vitamin E. Progressive dilatation and hypomotility of the entire gastrointestinal tract are demonstrated by radiographic studies and possibly related to infiltrate of ceroid pigment in the smooth muscle cell with resulting functional impairment. In the differential diagnosis of ceroidosis with other disease, scleroderma has the closest roentgenographic similarity. Pseudoobstruction of the small bowel which can develop must be treated conservatively to avoid unnecessary bowel resection.
