Prevalence of TT Virus in patients with chronic periodontitis, patients with aggressive periodontitis and healthy controls: a pilot study

Torque teno virus (TTV), a novel DNA virus resides in peripheral blood mononuclear cells and replicates when these cells get activated. The TTV replication shifts the immunobalance. Aim: To determine the presence of TTV in the gingiva of patients with aggressive periodontitis, patients withchronic periodontitis, and healthy controls, and to correlate the presence of TTV with probing pocket depth and clinical attachment level. Methods: Forty-two subjects (22 males and 20 females)aged 21 to 55 years were recruited for this study. Subjects were stratified into aggressive periodontitis (Group I), chronic periodontitis (Group II) and healthy controls (Group III). Gingival tissue biopsy was taken from all the subjects and the presence of TTV was analyzed using PCR and 2% agarose gel electrophoresis. Results: TTV was identified in half of the subjects and more number of subjects with periodontitis have TT virus compared to controls. There was significant association between presence of TT virus and pocket depth, clinical attachment level. Conclusions: The findings from the present study shows that there was no significant association between TT virus and periodontitis, even though it was isolated from more number of subjects with aggressive periodontitis, and TTV was associated with pocket depth and clinical attachment level. These findings need to be investigated in further studies.

Management of mucous membrane pemphigoid with dapsone plus weekly steroid injections in a young patient: a case report / Tratamento de penfigóide membranoso mucoso com dapsona e injeções semanais de esteróide em um paciente jovem: relato de caso

Purpose: Mucous Membrane Pemphigoid (MMP) is an autoimmune subepithelial blistering disorder usually affecting older individuals. This paper describes the pharmacological management of MMP in a young patient. Case description: A 23 year-old woman showed erythematous ulcerative gingiva in the maxillary palatal region and around the retromolar region. A perilesional excisional biopsy was done, and the histologic and immunohistochemical analysis confirmed the clinical diagnosis of MMP as the cause of desquamative gingivitis in this patient. The patient was treated with topical steroids plus daily Dapsone 100 mg and weekly steroid injections (40 mg). The lesions began to resolve after 12 weeks of therapy. Conclusion: This case of MMP in a young female patient was effectively managed with a combination therapy of topical steroids, Dapsone and steroid injections.

Objetivo: O penfigóide membranoso mucoso (PMM) é uma desordem autoimume subeptelial bolhosa que geralmente afeta indivíduos mais velhos. Este relato de caso descreve a abordagem farmacológica do PMM em uma paciente jovem. Descrição do caso: Uma paciente do sexo feminino, com 23 anos de idade, apresentava a gengiva eritematosa e ulcerada na região palatina e na região retromolar. A biópsia excisional total foi realizada e as análises histológica e de imuno-histoquímica confirmaram o diagnóstico clínico de PMM como causa da gengivite descamativa nesta paciente. A paciente foi tratada com esteróides tópicos, Dapsona 100 mg diariamente e injeções de esteróides mensais (40 mg). A resolução das lesões se iniciou após 12 semanas de terapia medicamentosa. Conclusão: Este caso de PMM em uma paciente jovem foi efetivamente tratado com uma terapia combinada de esteróides tópicos, Dapsona e injeções de esteróides.
