There is a need for reeducation of the population, especially in developed countries, as to the value of cereals in the diet. Cereals provide calories and important nutrients to the diet. Refined cereal products and unrefined cereals have certain advantages and disadvantages. With refinement, some nutrients and fiber are removed, but the body is better able to make use of certain nutrients. Essential nutrients are being replaced through fortification to compensate for losses in processing. The high fiber content of unrefined cereal products is believed to aid in the prevention of certain diseases. Special dietary bakery products have been introduced for the treatment of conditions generally exacerbated by standard food items. The increased consumption of cereal products appears warranted as a means of decreasing the saturated fat and cholesterol consumption. Cereals and cereal products have been mentioned in connection with allergies, celiac disease, schizophrenia, obesity, dental caries, cancer, atherosclerosis, goiter, and diverticulosis. This review discusses the possible role of cereals in the prevention or cause of these health problems.

Production of a leukocyte migration inhibition factor by peripheral blood lymphocytes in response to challenge with gluten fractions was studied in hospitalized patients with schizophrenia and other psychoses compared with normal individuals and with children and adolescents with celiac disease. The schizophrenic and other psychotic patients could be subdivided into two groups, one that responded in the leukocyte migration inhibition factor test as the celiac patients did and one that responded as the normal control subjects did. The psychotic and schizophrenic patients did not show any evidence of malabsorption. The authors speculate that gluten may be involved in biological processes in the brain in certain psychotic individuals.

In an aseptic microbiological assay of folate compounds and their breakdown compounds, using Lactobacillus casei, Streptococcus faecalis, and Pediococcus cerevisiae, 4a-hydroxy-5methyl-4,5,6,7-tetrahydrofolate and 5-methyl-5,8-dihydrofolate were inactive under all conditions to all three organisms and 5-methyl-5,6-dihydrofolate was inactive unless ascorbate was present in the incubation medium, and then only to L. casei. 5-Methyltetrahydrofolate was active only for L. casei, and activity in purified samples to S. faecalis was due to trace amounts of folic acid. Analysis of S. faecalis values in the serum in normal subjects and in patients with various disorders showed that levels of 10-formyltetrahydrofolate are raised in coeliac disease, leukaemia, rheumatoid arthritis, and schizophrenia. 5-Methyltetrahydrofolate is readily absorbed by normal human subjects and by patients with pernicious anaemia but poorly absorbed by patients with coeliac disease or leukaemia. 5-Methyl-5,6-dihydrofolate was quickly absorbed by normal human subjects, being reflected by a considerably raised level of 5-methyltetrahydrofolate in serum when sodium bicarbonate was given by mouth before the 5-methyl-5,6-dihydrofolate. These higher levels were comparable to those in patients with pernicious anaemia after oral administration of 5-methyl-5,6-dihydrofolate. Oral 5-methyl-5,8-dihydrofolate and 4a-hydroxy-5-methyl-tetrahydrofolate did not appear as microbiologically active folates in the serum. The findings of this study suggest that the availability for biological utilisation of the major dietary folate compounds will depend on the amount of gastric acidity and of ascorbate in the intestinal chyme. Many may be unavailable for metabolic utilization in the body.

To test the hypothesis of an association between schizophrenia and coeliac disease, the sera of 380 chronic schizophrenic in-patients in two mental hospitals in the West of Ireland have been screened for the presence of reticulin antibodies. Antibodies were found in 26 patients. Twenty-one of these patients were further studied by proximal duodenal mucosal biopsy. None of the biopsies showed the morphological and histological features found in untreated coeliac disease. The incidence of reticulin antibodies in schizophrenic patients and controls is similar. The findings of this study lead to the rejection of the hypothesis of a positive genetic relationship between schizophrenia and coeliac disease.

We have presented a single case of cavernous hemangioma of the spleen with cystic formation. We believe this is the first reported case associated with schizophrenia. Splenic scan demonstrated only a thin rim of functioning tissue. In the absence of a reliable history, celiac angiography provided the most important preoperative information on this large, barely functioning cystic spleen. A generous incision gave the required exposure for removal. The size of the cyst and the amount of compression and deviation of the splenic artery encouraged us to use a thoracoabdominal incision. We believe this is the 75th case of cystic hemangioma of the spleen reported in the literature.

Schizophrenic patients have low concentrations of PGE-1, n-6 fatty acids, vitamin C and zinc, elevated brain levels of dopamine and high plasma levels of interleukin-2 receptors (IL-2R). IL-2R plasma titers can be raised in celiac patients by administering wheat. These findings are both consistent with and supportive of the GI T-lymphocyte theory of schizophrenia.

Gastrointestinal permeability was assessed by means of absorption of 51Cr-labelled EDTA in 24 patients with schizophrenia (12 in relapse and 12 in remission). The results were compared with those for patients with coeliac disease and those for normal controls. Significant differences between the schizophrenic patients and the normal controls were not established. The results for the schizophrenic patients in remission were no different from those for the patients in relapse, and there was no evidence from the study of an effect on gastrointestinal permeability of either anticholinergic or antidepressant medication. It is concluded that schizophrenia is, at least in the majority of cases, unrelated to coeliac disease.

Because of a possible relationship between schizophrenia and celiac disease, a condition in some individuals who are sensitive to wheat gluten proteins in the diet, there has been interest in observations that peptides derived from wheat gluten proteins exhibit opioid-like activity in in vitro tests. To determine the origin of the peptides exhibiting opioid activity, wheat proteins were fractionated by size (gel filtration), by charge differences (ion exchange chromatography) and by differences in hydrophobicity (reversed-phase HPLC). These fractions were hydrolyzed by pepsin or pepsin and trypsin and the resulting peptides separated by gel filtration chromatography. The separated peptides were tested for opioid-like activity by competitive binding to opioid receptor sites in rat brain tissue in the presence of tritium-labeled dihydromorphine. The peptides showed considerable differences in activity; while some peptides exhibited no activity, 0.5 mg of the most active peptides were equivalent to 1 nM of morphine in the binding assay. The most active peptides were derived from the gliadin fraction of the gluten complex.

Loci conferring susceptibility to schizophrenia, coeliac disease, and orofacial clefting have been assigned to the 6p23-p25 region of human chromosome 6. To facilitate the identification of candidate genes we have sublocalized and ordered 39 ESTs assigned to this interval by radiation hybrid mapping. This was achieved by generating PAC contigs containing the ESTs, genetic markers, and random STSs. For full integration into previously published data a single YAC contig spanning 6p23-p25 was used to unambiguously order the PAC contigs and ESTs along the chromosome. The majority of the ESTs (31/39) were positioned in the 6p23-p24 interval at the proximal half of the map, and of these 8 are located within a single PAC clone. The order of known genes in this region is cen-CD83-ZNF40-EDN1-(GCNT2, CAPZB)-TFAP2-BMP6-DSP-tel.

Psychiatric symptoms and psychological behavioral pathologies are common in patients with untreated coeliac disease. There are several case reports of coexistence of coeliac sprue and depression, schizophrenia and anxiety. Views on association between coeliac disease and psychiatric disturbances and results of the most important studies are discussed. Biological background is referred. Malabsorption and deficiency of aminoacids and vitamins implicate reduction of synthesis of neurotransmitters in the central nervous system. Psychiatric symptoms could also be linked to immunological disregulation in coeliac patients. Psychological pathologies do appear in treated and untreated coeliacs, the need of psychological support is stressed. Coeliac disease should be taken into consideration in patients with psychiatric disorders, particularly if they are not responsive to psychopharmacological therapy, because withdrawal of gluten from the diet usually results in disappearance of symptoms. In recent years, an increased incidence of subclinical/silent coeliac disease has been reported. Psychiatric symptoms and psychological behavioral pathologies could be the only clinical manifestation of coeliac disease, but the epidemiological aspects need further investigation.
