ABSTRACT

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.

ABSTRACT

BACKGROUND AND OBJECTIVE: The increased use of epidural analgesia with catheter leads to the need to demonstrate the safety of this method and know the incidence of catheter colonization, inserted postoperatively for epidural analgesia, and the bacteria responsible for this colonization. METHODS: From November 2011 to April 2012, patients electively operated and maintained under epidural catheter for postoperative analgesia were evaluated. The catheter tip was collected for semiquantitative and qualitative microbiological analysis. RESULTS: Of 68 cultured catheters, six tips (8.8%) had positive cultures. No patient had superficial or deep infection. The mean duration of catheter use was 43.45 h (18-118) (p = 0.0894). The type of surgery (contaminated or uncontaminated), physical status of patients, and surgical time showed no relation with the colonization of catheters. Microorganisms isolated from the catheter tip were Staphylococcus aureus, Pseudomonas aeruginosa and Sphingomonas paucimobilis. CONCLUSION: Postoperative epidural catheter analgesia, under these study conditions, was found to be low risk for bacterial colonization in patients at surgical wards. .


OBJETIVOS: O aumento do uso de analgesia pela via peridural com uso de cateteres leva à necessidade de se demonstrar a segurança do método. O presente estudo teve como objetivo conhecer a incidência de colonização de cateteres inseridos para analgesia peridural no pós-operatório e as bactérias responsáveis por estas colonizações. MÉTODOS: No período de novembro de 2011 a abril de 2012 foram avaliados pacientes operados eletivamente mantidos sob analgesia por cateter peridural no pós-operatório. A ponta do cateter foi coletada para análise microbiológica semi-quantitativa e qualitativa. RESULTADOS: Seis (8,8%) pontas dos 68 cateteres cultivados apresentaram culturas positivas. Nenhum paciente apresentou infecção superficial ou profunda. O tempo médio de permanência do cateter foi de 43,45 horas (18-118 horas) (p = 0,0894). O tipo de cirurgia (contaminada ou não contaminada), estado físico dos pacientes e tempo cirúrgico não mostraram relação com a colonização dos cateteres. Os micro-organismos isolados da ponta de cateter foram Staphylococcus aureus, Pseudomonas aeruginosa e Sphingomonas paucimobilis. CONCLUSÃO: Conclui-se que, a analgesia por cateter peridural no pós-operatório, nas condições do presente estudo, revelou-se procedimento com baixo risco de colonização bacteriana em pacientes de enfermarias cirúrgicas. .


OBJETIVOS: El aumento del uso de analgesia por vía epidural con el uso de catéteres nos lleva a la necesidad de demostrar la seguridad del método. El presente estudio tuvo como objetivo conocer la incidencia de la colonización de catéteres insertados para la analgesia epidural en el postoperatorio y las bacterias responsables de estas colonizaciones. MÉTODOS: En el período de noviembre de 2011 a abril de 2012, se evaluaron pacientes operados electivamente que fueron mantenidos bajo analgesia por catéter epidural en el postoperatorio. La punta del catéter fue recolectada para análisis microbiológico semicuantitativo y cualitativo. RESULTADOS: Seis (8,8%) puntas de los 68 catéteres cultivados presentaron cultivos positivos. Ningún paciente presentó infección superficial o profunda. El tiempo medio de permanencia del catéter fue de 43,45 h (18-118 h) (p = 0,0894). El tipo de cirugía (contaminada o no contaminada), estado físico de los pacientes y tiempo quirúrgico no mostraron relación con la colonización de los catéteres. Los microorganismos aislados de la punta del catéter fueron Staphylococcus aureus, Pseudomonas aeruginosa y Sphingomonas paucimobilis. CONCLUSIÓN: Concluimos que la analgesia por catéter epidural en el postoperatorio, en las condiciones del presente estudio, mostró ser un procedimiento con bajo riesgo de colonización bacteriana en pacientes quirúrgicos. .
