Soluble LPS receptor CD14 is increased in saliva of patients with geographic tongue.

OBJECTIVES: The soluble bacterial pattern recognition receptor, sCD14 augments inflammatory responses in oral cavity. The aim of the study was to investigate whether patients with geographic tongue (GT) with and without fissured tongue (FT) have impaired inflammatory regulation, manifesting as increased levels of sCD14 in the saliva. MATERIAL AND METHODS: An enzyme-linked immunosorbent assay was used to measure the amount of sCD14 in whole and parotid saliva of patients diagnosed with GT (GT whole, n = 21; GT parotid, n = 23) and control subjects (GT whole, n = 25; GT parotid, n = 18). The levels of sCD14 were also evaluated according to our previous clinical assessment of GT based on the number of lesions detected on the tongue, as 'mild' (a single lesion), 'moderate' (2-5 lesions), or 'severe' (≥6 lesions). Diagnosis of FT was established when multiple grooves or fissures were observed on the dorsal and lateral surfaces of the tongue. RESULTS: GT patients had significantly higher sCD14 levels in whole (p<.05) and parotid saliva (p<.001), compared with controls. GT patients with FT had significantly increased sCD14 levels only in parotid saliva. A gradual increase in sCD14 levels in parotid and unstimulated saliva was seen in GT patients with multiple tongue lesions compared with single lesions. CONCLUSIONS: GT patients had increased sCD14 in both parotid and unstimulated saliva. sCD14 seems to increase local inflammatory responses, which suggests its involvement in the pathophysiology of GT.

Common Oral Lesions.

Familiarity with common oral conditions allows clinicians to observe and treat patients in the primary care setting or refer to a dentist, oral surgeon, otolaryngologist, or other specialist. Recurrent aphthous stomatitis (canker sores) is the most common ulcerative condition of the oral cavity. Recurrent herpes simplex labialis and stomatitis also commonly cause oral ulcers. Corticosteroids, immunocompromise, antibiotics, and dentures can predispose patients to oral candidiasis. Benign migratory glossitis (geographic tongue) occurs in up to 3% of the population but generally lacks symptoms, although some people experience food sensitivity or a burning sensation. Hairy tongue is associated with a low fiber diet, tobacco and alcohol use, and poor oral hygiene in older male patients. Generally, hairy tongue is asymptomatic except for an unattractive appearance or halitosis. Tobacco and alcohol use can cause mucosal changes resulting in leukoplakia and erythroplakia. These can represent precancerous changes and increase the risk of squamous cell carcinoma. Mandibular and maxillary tori are common bony cortical outgrowths that require no treatment in the absence of repeat trauma from chewing or interference with dentures. Oral lichen planus occurs in up to 2% of individuals and can present as lacy reticulations or oral erosions and ulcerations. Traumatic buccal mucosal fibromas and labial mucoceles from biting can be excised.

Increased levels of calprotectin in the saliva of patients with geographic tongue.

OBJECTIVE: We investigated whether patients with geographic tongue have increased salivary levels of calprotectin and whether there is a correlation between the salivary levels of calprotectin and interleukin 8 (IL-8), which is another marker of inflammation. METHODS: Twenty-three patients diagnosed with geographic tongue and 32 control subjects without oral mucosal lesions were included in the study. The patients with geographic tongue were classified based on clinical appearance and number of oral lesions. ELISAs were used to determine the levels of calprotectin and IL-8 in whole saliva samples. RESULTS: There was a statistically significant increase in the salivary output of calprotectin in patients with geographic tongue compared with the healthy controls (62 ± 9,1 vs. 37,5 ± 4,7 µg/min; p = .0134). Furthermore, the levels of calprotectin correlated positively with the number of oral lesions in patients with geographic tongue. There was also a significant and positive correlation between the salivary levels of calprotectin and IL-8, both for the patients with geographic tongue and the controls. CONCLUSION: This study supports the notion that GT is an inflammatory disease, in which the activation of neutrophils and production of calprotectin in the saliva may play roles in its pathogenesis.

Evaluation of the Th17 pathway in psoriasis and geographic tongue.

BACKGROUND: Psoriasis is a skin-articular disease with unclear etiopathogenesis. It has been suggested that the disease is immune-mediated by T-lymphocytes, predominantly Th17 cells. Similar to psoriasis, geographic tongue is an inflammatory disease with participation of Th17 cells and direct correlation with psoriasis. OBJECTIVE: To investigate and compare the inflammatory responses and the Th17 pathway in psoriasis and geographic tongue. METHODS: This was a cross-sectional study with 46 participants that were categorized into three groups: (A) patients with psoriasis vulgaris; (B) patients with geographic tongue and psoriasis; (C) patients with geographic tongue without psoriasis. All patients underwent physical examination, and a skin and oral biopsy for histopathological examination and immunohistochemical analysis with anti-IL6, anti-IL17, and anti-IL23 antibodies. RESULTS: Histological analysis of all lesions showed mononuclear inflammatory infiltrate. However, moderate intensity was prevalent for the patients with geographic tongue and psoriasis and geographic tongue groups. Immunopositivity for the antibodies anti-IL6, anti-IL17, and anti-IL23 revealed cytoplasmic staining, mainly basal and parabasal, in both psoriasis and geographic tongue. Regarding IL-6, in patients with geographic tongue and psoriasis cases the staining was stronger than in patients with geographic tongue without psoriasis cases. IL-17 evidenced more pronounced and extensive staining when compared to the other analyzed interleukins. IL-23 presented similar immunopositivity for both geographic tongue and psoriasis, demonstrating that the neutrophils recruited into the epithelium were stained. STUDY LIMITATION: This study was limited by the number of cases. CONCLUSION: The inflammatory process and immunostaining of IL-6, IL-17, and IL-23 were similar in geographic tongue and psoriasis, suggesting the existence of a type of geographic tongue that represents an oral manifestation of psoriasis.

Geographic stomatitis with palate involvement.

Benign migratory glossitis or geographic tongue is a benign condition that usually manifests as asymptomatic erythematous and migratory circinate patches, involving the lateral and dorsal aspects of the tongue. Extra-lingual lesions uncommonly occur and are mainly located on labial and buccal mucosae, lips and floor of the mouth. The present report describes one patient with a geographic lesion on the hard palate associated with lingual lesions and another patient who had multiple geographic lesions both in the hard and soft palate without lingual lesions. We found 64 cases in the English literature of ectopic locations with 22 palate involvement. No case of simultaneous involvement of the hard and the soft palate was found.

Treatment of symptomatic benign migratory glossitis: a systematic review.

OBJECTIVE: The aim of this systematic review is to summarize the results of all published studies on symptomatic benign migratory glossitis and evaluate the best available treatment. METHODS: We searched the Cochrane Library, EMBASE, LILACS, PubMed, Scopus, and Web of Science for articles published up to September 2017, with no time restriction. We considered only articles published in English that evaluated the treatment of symptomatic benign migratory glossitis in children and adults. The protocol for this systematic review was registered at the international prospective register of systematic reviews (PROSPERO) as CRD42017074096. RESULTS: Of the 840 identified studies, 11 were included in our sample. Multiple treatment modalities were described for the treatment of symptomatic benign migratory glossitis. CONCLUSIONS: There is a very low level of evidence for the treatment of symptomatic benign migratory glossitis, with substantial methodological heterogeneity among the evaluated studies. In summary, we could identify no specific treatment for symptomatic benign migratory glossitis. CLINICAL RELEVANCE: In clinical practice, at the outpatient clinic of oral medicine, we attend to many patients diagnosed with benign migratory glossitis, with varying intensity of pain ranging from mild to severe. Treating this disease is a formidable challenge for clinicians. Therefore, we performed a systematic review of benign migratory glossitis to identify the best evidence-based treatment available for this condition. We believe that this article may be useful in guiding clinicians on the choice of treatment.

Host and clinical aspects in patients with benign migratory glossitis.

OBJECTIVE: Investigate the association of clinical, cytological and genetic characteristics with benign migratory glossitis (BMG). STUDY DESIGN: Sample consisted of 175 patients, 44 with BMG and 131 control patients. Clinical examination and DMFT index were assessed. Cytological evaluation determined cell morphology and morphometry. Genetic evaluation was performed by analysing IL6 polymorphisms by real-time PCR. Univariate and multivariate analyses were performed (p<0.05). RESULTS: There was a higher level of anxiety, DMFT score and a prevalence of fissured tongue in BMG group. A high mean nuclear/cytoplasmic area ratio was observed in patients with BMG. There was predominance of Papanicolaou class II I BMG group. IL6 allele G rs2069843 polymorphism was associated with BMG in the dominant model. In multivariate analysis, DMFT and anxiety scale remained associated with BMG.

Geographic tongue and psoriasis: clinical, histopathological, immunohistochemical and genetic correlation - a literature review.

Geographic tongue is a chronic, inflammatory, and immune-mediated oral lesion of unknown etiology. It is characterized by serpiginous white areas around the atrophic mucosa, which alternation between activity, remission and reactivation at various locations gave the names benign migratory glossitis and wandering rash of the tongue. Psoriasis is a chronic inflammatory disease with frequent cutaneous involvement and an immunogenetic basis of great importance in clinical practice. The association between geographic tongue and psoriasis has been demonstrated in various studies, based on observation of its fundamental lesions, microscopic similarity between the two conditions and the presence of a common genetic marker, human leukocyte antigen (HLA) HLA-C*06. The difficulty however in accepting the diagnosis of geographic tongue as oral psoriasis is the fact that not all patients with geographic tongue present psoriasis. Some authors believe that the prevalence of geographic tongue would be much greater if psoriatic patients underwent thorough oral examination. This study aimed to develop a literature review performed between 1980 and 2014, in which consultation of theses, dissertations and selected scientific articles were conducted through search in Scielo and Bireme databases, from Medline and Lilacs sources, relating the common characteristics between geographic tongue and psoriasis. We observed that the frequency of oral lesions is relatively common, but to establish a correct diagnosis of oral psoriasis, immunohistochemical and genetic histopathological analyzes are necessary, thus highlighting the importance of oral examination in psoriatic patients and cutaneous examination in patients with geographic tongue.
