Close association of HLA-B52 and HLA-B44 antigens in Israeli Arab adolescents with recurrent aphthous stomatitis.

OBJECTIVES: To investigate the incidence and clinical features of recurrent aphthous stomatitis (RAS) among Israeli Arab adolescents and to determine the HLA typing profile in affected subjects. STUDY DESIGN: Cross-sectional study. SETTING: Junior high school in the largest Arab town in Israel. PARTICIPANTS: Four hundred seventy-seven Israeli Arab junior high school students filled out a questionnaire. Students who reported more than 4 episodes of RAS during the previous year were interviewed by telephone. Those whose responses were confirmed were invited to the clinic. Of these, 22 were chosen at random for HLA typing. Findings were compared with those in 117 healthy Israeli Arabs who were candidate donors of bone marrow to patients at the Institute of Hematology-Oncology, Schneider Children's Medical Center of Israel, Petah Tiqva. RESULTS: Recurrent aphthous stomatitis was confirmed in 80 subjects (16.7%). Of the 22 patients who underwent HLA typing, 7 (31.4%) had HLA-B52 antigens and 8 (36.4%) had HLA-B44 antigens; corresponding figures for the control group were 10 subjects (8.5%) (P = .007) and 9 subjects (7.7%) (P = .001), respectively. CONCLUSIONS: There is a close association of HLA-B52 and HLA-B44 in Israeli Arab youths with RAS. Long-term follow-up is needed to determine the relationship between RAS and Behçet disease.

Pemphigus mimicking aphthous stomatitis.

BACKGROUND: The aim of this report is to highlight the case that pemphigus vulgaris (PV) may mimic aphthous stomatitis. Pemphigus classically causes persistent oral ulceration. METHODS AND RESULTS: We report five patients from southern Europe, who presented with recurrent oral ulceration mimicking aphthous stomatitis, but who proved by histology, immunostaining and antibodies against epithelial intercellular substance to have PV. CONCLUSION: It is advisable to assay antibodies against desmoglein 3 in patients who appear to suffer recurrent aphthous stomatitis (RAS) with atypical ulceration for location and in adulthood.

[Treatment of recurrent aphthous stomatitis with application of a preparation of a hesperidin 5.0%].

Open randomized 2-year trial has been performed to analyze effectiveness of Unguentum of a hesperidin developed by us for the treatment of recurrent aphthous stomatitis. 80 patients with recurrent aphthous stomatitis in the age from 15 till 60 years from the contingent of the polyclinic of the veterans of Tbilisi were studied. After inclusion of the preparation into the treatment the pain and duration of inflammatory process have been decreased; the complications were not observed. In the group of patients getting treatment with hesperidin, frequency of unsatisfactory outcomes decreased significantly (chi(2)=9,8, p < 0,05). Reduction of relative risk of unsatisfactory outcomes was about 0,8 (95% CI: 0,29-0,86), reduction of absolute risk - 0,33 (95% CI: 0,13-0,52). It may be concluded that application of a preparation may be considered as one of the options for the treatment of recurrent aphthous stomatitis.

Helicobacter pylori DNA in recurrent aphthous stomatitis.

BACKGROUND: Considering not only the fact that recurrent aphthous stomatitis (RAS) and stomach ulcers are immunologically mediated ulcers associated with Helicobacter pylori, but also the recent evidence that anaemia can be associated with both diseases, and the discovery of H. pylori in the oral mucosa led us to hypothesize that this bacteria may be related to RAS pathogenesis. METHODS: Thirty-six consecutive subjects affected by minor and major forms of RAS and 48 healthy volunteers were included in the present study. The nested polymerase chain reaction (PCR) technique was used to detect the presence of H. pylori in the oral lesion, the normal contralateral mucosa of patients affected by RAS and the oral mucosa of control subjects. The chi2- and Fisher's tests were used for statistical analysis. RESULTS: No association between RAS lesions and H. pylori was observed. However, 14 out of 36 (38.9%) of the patients with RAS were found to show the presence of H. pylori DNA in the lesion and/or contralateral mucosa. Sixteen out of 48 (33.3%) of the patients without RAS (control subjects) were positive (P > 0.05). CONCLUSION: The present study does not give support to the assumption that H. pylori could be involved in RAS development.

Recurrent aphthous stomatitis: current concepts of etiology, pathogenesis and management.

Recurrent aphthous stomatitis (RAS) is a common oral disorder, however, despite detailed clinical, immunologic, hematologic and microbiologic investigation, the etiology of RAS remains unknown. At present, topical steroids and antimicrobial mouth rinses are the mainstays of treatment, but there is still no means of preventing recurrence of the oral ulceration.

[PFAPA syndrome: periodic fever, adenitis, pharyngitis and aphthous stomatitis].

A syndrome involving periodic fever, pharyngitis, adenitis and aphthous stomatitis is described in 8 children. Attacks are characterized by abrupt onset of fever and, in addition to the above symptoms, by malaise, headache and abdominal pain. Mild leukocytosis and elevation of the erythrocyte sedimentation rate are found in the laboratory. Patients exhibit normal growth and development and are otherwise healthy. PFAPA is clinically benign, with no long-term sequelae. Recognition and diagnosis of the syndrome eliminate the need for intensive work-up. The cause remains unknown. No evidence linking bacterial, viral, or fungal pathogens to this syndrome has been found. No patient has exhibited atypical lymphocytosis or neutropenia, and all patients had normal levels of immunoglobulin. All had received antibiotics early in the course of their illness but without effect. Cimetidine has been discussed in the literature as a possible treatment, but the results are controversial.
