A series of 130 consecutive outpatients with recurrent aphthous stomatitis were screened at the oral medicine department, Glasgow Dental Hospital, for deficienciesin vitamin b12, folic acid, and iron. In 23 patients (17.7%) such deficiencies werefound; five were deficient in vitamin B12, seven in folic acid, and 15 in iron. Four had more than one deficiency. Out of 130 controls matched for age and sex 11 (8.5%) were found to have deficiencies. The 23 deficient patients with recurrent aphthaewere treated with specific replacement therapy, and all 130 patients were followed up for at least one year. Of the 23 patients on replacement therapy 15 showed complete remission of ulceration and eight definite improvement. Of the 107 patientswith no deficiency receiving local symptomatic treatment only 33 had a remission or wereimproved. This difference was significant (P less than 0.001). Most patients withproved vitamin B12 or folic acid deficiency improved rapidly on replacement therapy;those with iron deficiency showed a less dramatic response. The 23 deficient patientswere further investigated to determine the cause of their deficiencies and detect the presence of any associated conditions. Four were found to have Addisonian perniciousanaemia. Seven had a malabsorption syndrome, which in five proved to be a gluten-induced enteropathy. In addition, there were single patients with idiopathic proctocolitis, diverticular disease of the colon, regional enterocolitis, and adenocarcinoma of thecaecum. We suggest that the high incidence of deficiencies found in this series andthe good response to replacement therapy shows the need for haematological screening of such patients.

We present 4 cases of common variable immunodeficiency with main digestive clinical manifestations. In all four cases chronic diarrhea with intestinal malabsorption predominated, as well as the presence lymphoid nodular hyperplasia; in one case Giardia infestation could be identified; one patient also presented chronic pancreatitis, or recurrent aphthous stomatitis and active chronic hepatitis; sideroblastic anemia could be observed in another patient. All patients had favorable evolution during follow-up which lasted at least 14 months in substitutive treatment with immunoglobulins. One of our patients presented an elevated number of suppressor T lymphocytes, with inversion of the T helper/T suppressor ratio which improved with cimetidine treatment.

Jejunal biopsies of twenty-four patients with aphthous ulcers in whom malabsorption was not found, were studied. Four patients (16%) had subtotal villous atrophy and this structural change reversed after gluten withdrawal. There was a significant increase in intra-epithelial lymphocytes in the aphthous patients compared with healthy controls (p less than 0.001). The lymphocytic infiltration of the epithelium was higher, even in specimens with normal morphology (p less than 0.001). The findings suggest that a significant number of patients with recurrent aphthous stomatitis may have a mild form of gluten enteropathy.

Until a few years ago, celiac disease (CD) was thought to be a rare food intolerance that was confined to childhood and characterized by severe malabsorption and flat intestinal mucosa. Currently, CD is regarded as an autoimmune disorder that is common in the general population (affecting 1 in 100 individuals), with possible onset at any age and with many possible presentations. The identification of CD is challenging because it can begin not only with diarrhea and weight loss but also with atypical gastrointestinal (constipation and recurrent abdominal pain) and extra-intestinal symptoms (anemia, raised transaminases, osteoporosis, recurrent miscarriages, aphthous stomatitis and associated autoimmune disorders), or it could be completely symptomless. Over the last 20 years, the diagnostic accuracy of serology for CD has progressively increased with the development of highly reliable tests, such as the detection of IgA tissue transglutaminase and antiendomysial and IgG antideamidated gliadin peptide antibodies. The routine use of antibody markers has allowed researchers to discover a very high number of 'borderline' cases, characterized by positive serology and mild intestinal lesions or normal small intestine architecture, which can be classified as potential CD. Therefore, it is evident that the 'old celiac disease' with flat mucosa is only a part of the spectrum of CD. It is possible that serology could identify CD in its early stages, before the appearance of severe intestinal damage. In cases with a positive serology but with mild or absent intestinal lesions, the detection of HLA-DQ2 and HLA-DQ8 can help reinforce or exclude the diagnosis of gluten sensitivity.

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.
