Relationship of Helicobacter pylori seroprevalence with the occurrence and severity of psoriasis

Abstract: BACKGROUND: Psoriasis is a chronic inflammatory disease that affects the skin and joints and has a multifactorial etiology. Recently, it has been suggested that Helicobacter pylori infection may contribute as a trigger for the development of the disease. OBJECTIVES: To determine the prevalence of H. pylori seropositivity in patients with psoriasis and to evaluate the relation between disease severity and H. pylori infection. METHODS: H. pylori infection was assessed in psoriatic patients and controls by using H. pylori IgG quantitative enzyme immunoassay (ELISA test). The patients were classified according to the severity of the disease (PASI score). RESULTS: One hundred and twenty six patients with psoriasis (73 females and 53 males); mean age 50.48 years; 65 patients (51.59%) had severe psoriasis, 40 (31.75%) moderate psoriasis and 21 (16.67%) mild psoriasis. Twenty one healthy volunteers included as a control group, mean age of 41.05 years, 13 females and 8 males. One hundred and eleven patients with psoriasis tested serologically, 80 (72.07%) were seropositive compared with 7 positive volunteers (33.33%; P=0.002). Forty-nine (75.38%) patients with severe psoriasis were positive, 25 (62.50%) with moderate psoriasis were positive and 6 (28.57%) with mild psoriasis were positive (P=0.045). Study limitations: none. CONCLUSIONS: H. pylori infection influences the development of psoriasis and severity of the disease.

Perfil estomatológico de pacientes psoriátricos: análise de 50 casos / Stomatologic feactures in psoriatric patients: analysis of 50 cases

Introdução: a psoríase é uma doença dermatológica crônica que acomete cerca de 3% da população mundial e pode representar um fator importante de exclusão social. A manifestação bucal ainda é um assunto controverso na literatura sendo descrita como lesões brancas, eritematosas, úlceras e papuloescamosa. Objetivos - Avaliar a presença de manifestações bucais da psoríase, considerando-se a localização e as características clínicas das lesões encontradas, o sexo, a idade e a raça dos acometidos. Métodos - Estudo observacional, do tipo transversal, com pacientes que procuraram atendimento no ambulatório de dermatologiado Hospital de Clínicas da Universidade Federal de Uberlândia (HCUFU) entre dezembro de 2006 a novembro de 2007 (n=50). Resultados - A idade variou entre 7 e 78 anos com media de idade de 43,58 anos e mediana de 45 anos. Não houve predileção por sexo, sendo que 26 pacientes eram do sexo masculino e 24 feminino. No exame bucal foram encontradas lesões em 44% dos pacientes, sendo 16 lesões em língua (53,3%) na forma de fissuras ou áreas despapiladas, 2 em mucosa jugal (6,7%) na forma de placas brancas, 5 em lábio (16,7%) na forma de queilites e ressecamento e 7 lesões eritematosa sem palato (23,3%). Conclusões - Não foi possível identificar alteração que pudesse estar associada à psoríase, visto que nenhuma lesão acompanhou o quadro da doença cutâneaou teve diagnóstico histológico confirmado. Com relação às alterações em língua, tais como língua fissurada e língua geográfica, a incidência encontrada foi muito próxima a outros estudos em pacientes sem uma doença de base importante.

Introduction: psoriasis is a chronic dermatologic disease that affects at least 3% of the world population. Oral manifestation is still a controversy in the literature. It has been described by some authors in clinical case reports as white or erythematous lesions, ulcers and descamative papules. Objectives - To evaluate the presence of oral manifestations associated with psoriasis, considering location and clinical characteristics of the lesions and also gender, age and race of patients. Method - It was an observational,cross-sectional study of patients who sought for treatment at the Dermatology Service ofthe University Hospital (Uberlândia Federal University); between December 2006 and November 2007 (n=50) . Results - Age varied from 7 to 78 years, mean age of 43,58years and median of 45 years. There was no predominance of male (n=26) or female(n=24) patients. Lesions were found in 44% of patients, 16 (53,3%) of these lesions werein tongue, 2 (6,7%) white plaques in the cheeks, 5 (16,7%) lesion in lips as cheilitis anddryness and 7 (23,3%) erythematous areas in the hard palate. Conclusions - After all,it was not possible to make any specific association between oral lesions and psoriasis because the lesions did not follow the cutaneous disease stage nor was histologically confirmed. Also the tongue alterations incidence identified in this study was similar tothat found in population without other diseases.
