MANICURE/PEDICURE TECHNICIANS: BIOSECURITY KNOWLEDGE AND PRACTICES FOR VIRAL HEPATITIS

Objetivo: Investigar o conhecimento e as práticas de biossegurança para hepatites virais de manicures/pedicures. Métodos: Estudo descritivo, transversal, quantitativo, através de questionário, utilizando instrumento de coleta de dados autoaplicado elaborado pelos pesquisadores, contendo dados da população (sexo, idade, tempo de atuação profissional) e conhecimentos básicos sobre transmissão de hepatite e práticas de biossegurança e higiene. Resultados: Entrevistaram-se 96 manicures/pedicures que atuam no Noroeste do Paraná. A maioria das profissionais já ouviu falar da patologia, mas somente 41,7% (n=40) fizeram o exame para detecção do vírus da hepatite; 38,39% (n=77) relataram como via de transmissão o sangue e 31,8% (n=63), a relação sexual. A reutilização de materiais descartáveis foi relatada por 60,4% (n=58); 55,2% (n=53) realizam esterilização de materiais e 27,1% (n=26) não a realizam. Não ficou evidenciada associação significativa entre tempo de profissão e as variáveis utilizadas: ouviu sobre hepatite (p=0,77025), realização de exames (p=0,035476), reutilização de materiais descartáveis (p=0,42691), lavagem de mãos (p=0,32876), uso de luvas descartáveis (p=0,33752) e esterilização de materiais (p=0,84443). Conclusão: As manicures entrevistadas não conhecem as exigências da Vigilância Sanitária no que concerne à prevenção da transmissão de hepatites.

Primary dengue haemorrhagic fever in patients from northeast of Brazil is associated with high levels of interferon-b during acute phase

Dengue is an acute febrile disease caused by the mosquito-borne dengue virus (DENV) that according to clinical manifestations can be classified as asymptomatic, mild or severe dengue. Severe dengue cases have been associated with an unbalanced immune response characterised by an over secretion of inflammatory cytokines. In the present study we measured type I interferon (IFN-I) transcript and circulating levels in primary and secondary DENV infected patients. We observed that dengue fever (DF) and dengue haemorrhagic fever (DHF) patients express IFN-I differently. While DF and DHF patients express interferon-a similarly (52,71 ± 7,40 and 49,05 ± 7,70, respectively), high levels of circulating IFN-b were associated with primary DHF patients. On the other hand, secondary DHF patients were not able to secrete large amounts of IFN-b which in turn may have influenced the high-level of viraemia. Our results suggest that, in patients from our cohort, infection by DENV serotype 3 elicits an innate response characterised by higher levels of IFN-b in the DHF patients with primary infection, which could contribute to control infection evidenced by the low-level of viraemia in these patients. The present findings may contribute to shed light in the role of innate immune response in dengue pathogenesis.

Suppression of HIV-1 viral load after multiple changes in high active antiretroviral therapy: A case report

High active antiretroviral therapy (HAART) can reduce plasma viremia to levels below the limit of detection, leading to adequate immune recovery and clinical stability in most HIV-1-infected patients. However, the virus persists in reservoirs, and free virions can be found in the plasma. We report here the case of an HIV-infected patient diagnosed in 1999, who exhibited good adherence to medication and HAART efficacy after multiple protocol changes. In this study, we describe the clinical features, chronological changes in HIV viral load and CD4+ T-cell count, and treatment outcomes of multiple combinations of antiretrovirals (ARV).The patient presented cycles of viral load during treatment ranging from undetectable, low, and intermediate HIV-1 RNA levels, to levels above the limits of quantification. A therapeutic regimen intensified with raltegravir (RAL) promoted constant depletion of HIV viral load and an increase in CD4+ T-cells. The report shows that enhanced HAART efficacy using RAL can reduce HIV viral load.
