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.

Vitamins are a group of organic compounds occurring naturally in food and are necessary for good health. Lack of a vitamin may lead to a specific deficiency syndrome, which may be primary (due to inadequate diet) or secondary (due to malabsorption or to increased metabolic need), and it is rational to use high-dose vitamin supplementation in situations where these clinical conditions exist. However, pharmacological doses of vitamins are claimed to be of value in a wide variety of conditions which have no, or only a superficial, resemblance to the classic vitamin deficiency syndromes. The enormous literature on which these claims are based consists mainly of uncontrolled clinical trials or anecdotal reports. Only a few studies have made use of the techniques of randomisation and double-blinding. Evidence from such studies reveals a beneficial therapeutic effect of vitamin E in intermittent claudication and fibrocystic breast disease and of vitamin C in pressure sores, but the use of vitamin A in acne vulgaris, vitamin E in angina pectoris, hyperlipidaemia and enhancement of athletic capacity, of vitamin C in advanced cancer, and niacin in schizophrenia has been rejected. Evidence is conflicting or inconclusive as to the use of vitamin C in the common cold, asthma and enhancement of athletic capacity, of pantothenic acid in osteoarthritis, and folic acid (folacin) in neural tube defects. Most of the vitamins have been reported to cause adverse effects when ingested in excessive doses. It is therefore worthwhile to consider the risk-benefit ratio before embarking upon the use of high-dose vitamin supplementation for disorders were proof of efficacy is lacking.

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.

Both schizophrenia and celiac disease involve a genetic component. Several lines of evidence have shown a genetic relationship between these two conditions. Celiac disease is characterized by damage to the microscopic finger-like projections called villi, which line the small intestine and play a significant role in digestion, due to an inflammatory condition caused by a reaction to wheat gluten or related rye and barley proteins. Celiac disease represents not only malabsorption leading to a poor nutritional condition but also an alteration of gut permeability. Individuals with a history of a childhood celiac condition have a raised risk of developing schizophrenia. Psychotic symptoms often occur in adult celiac disease. It can be hypothesized that apart from malnutrition, the meeting point for the gene-environment interaction may be an alteration in gut permeability, in which the gut may lose its capacity to block exogenous psychosis-causing substances that may enter the body thus causing the development of schizophrenia and other mental conditions. To support this hypothesis, the conditional test was conducted to look at the combined effect of the CLDN5 gene involved in forming permeability barriers and the DQB1 gene that has been found to be associated with celiac disease. The results demonstrate that these two genes possibly work together in conferring a susceptibility to schizophrenia.

The paper describes a clinical case of celiac disease with grade 3 malabsorption, which is associated with recurrent aphthous stomatitis and schizophrenia. On readmission after 8 months of strict adherence to his gluten-free diet, the patient was observed to be in clinical remission and to have normalized laboratory indices and immunological tests. The signs of recurrent stomatitis disappeared. However, the symptoms of the mental disease remained.
