Cell phenotypes as activity biomarkers in patients with Systemic Lupus Erythematosus

The pathogenesis of systemic lupus erythematosus (SLE) is complex. Few studies in Brazilian population have addressed cell phenotypes associated with immunological responses and their associations with SLE activity. The aim of this study is to investigate cell phenotypes associated to SLE diagnosis, treatment and activity. Twenty-eight SLE female patients (17 inactive, 11 active) and 10 healthy women were included in this study. Markers of natural killer (Nk), T and B cells in peripheral blood were evaluated by flow cytometry. Nkt cells were decreased only in SLE active patients. Activated CD4+, regulatory T FoxP3+ and B cells were decreased in both active and inactive SLE patients, compared to control group. The data corroborate the disruption of immune regulatory response in SLE patients and suggest phenotipic changes as possible biomarkers of SLE activity

Síndrome de Felty e Calazar: um desafio para o reumatologista

Os autores relatam o caso de uma paciente com artrite reumatoide que evoluiu com grave neutropenia e esplenomegalia, sendo firmado o diagnóstico de Síndrome de Felty, que posteriormente desenvolveu Calazar. Ambas têm apresentação clínica e laboratorial semelhantes, tornando o diagnóstico diferencial difícil. O relato deste caso objetiva chamar a atenção para o reconhecimento da infecção por leishmaniose visceral em pacientes portadores de doenças reumáticas, assim como a possibilidade de um paciente com Calazar mimetizar um quadro de doença reumática sistêmic

Contribuição dos métodos de imagem na avaliação do envolvimento pulmonar na dermatomiosite

The differential cross-section for the production of a $W$ boson in association with a top quark is measured for several particle-level observables. The measurements are performed using 36.1 fb$^{-1}$ of $pp$ collision data collected with the ATLAS detector at the LHC in 2015 and 2016. Differential cross-sections are measured in a fiducial phase space defined by the presence of two charged leptons and exactly one jet matched to a $b$-hadron, and are normalised with the fiducial cross-section. Results are found to be in good agreement with predictions from several Monte Carlo event generators
