Multiple sclerosis is mediated by self-reactive myelin T and B cells that lead to axonal and myelin damage. The immune response in multiple sclerosis involves the participation of CD4⁺ T cells that produce cytokines and chemokines. This participation is important to find markers for the diagnosis and progression of the disease. In our work, we evaluated the profile of cytokines and chemokines, as well as the production of double positive CD4⁺ T cells for the production of IFNγ IL-17 in patients with multiple sclerosis, at different stages of the disease and undergoing different treatments. We found that relapsing–remitting patients had a significant increase in IL-12 production. About IL-5, its production showed significantly higher levels in secondarily progressive patients when compared to relapsing–remitting patients. IFN-γ production by PBMCs from secondarily progressive patients showed significantly higher levels. This group also had a higher percentage of CD4⁺ IFNγ⁺ IL-17⁺ T cells. The combination of changes in certain cytokines and chemokines together with the presence of IFNγ⁺ IL-17⁺ double positive lymphocytes can be used to better understand the clinical forms of the disease and its progression.

The effect of physical activity on the immune system is still poorly understood in cases of systemic lupus erythematosus (SLE). Therefore, our aim was to investigate differences in the serum levels of cytokines (IL-2, IL-5, IL-6, IL-8, IL-10 and TNF-α) and the numbers of CD11b + and CXCR2 + neutrophils and lymphocytes in women with SLE undergoing drug treatment, without (n = 9) or with (n = 5) 4 months of kinesiotherapy. Parameters related to functional capacity were also analyzed. In the case of the patients who were not submitted to kinesiotherapy, there were reductions in the levels of IL-5, IL-6 and IL-10, and an increase in the number of CD11b + leukocytes, in addition to an increase in abdominal circumference after the monitoring time. Patients submitted to kinesiotherapy did not present changes in serum cytokines or in the numbers of CD11b + and CXCR2 + neutrophils and lymphocytes, but there were increases of flexibility and strength, as well as a reduction in pain sensation after the monitoring time. In conclusion, kinesiotherapy was able to increase flexibility and reduce pain in SLE patients without influencing immune parameters.

INTRODUÇÃO: O pênfigo é uma doença autoimune, caracterizada por vésico-bolhas cuja manifestações clínicas crônicas geram alterações na qualidade de vida. Existem relatos de pênfigo em vários continentes; porém ocorre predominantemente na região centro-norte da América do Sul. No Brasil, a doença predomina nos estados do Centro-Oeste e Sudeste. Objetivou-se avaliar o perfil e a qualidade de vida de pacientes com pênfigo em uma cidade brasileira, para intervenção fisioterapêutica. MÉTODOS: Foram analisados 15 prontuários de pacientes institucionalizados; contudo, 7 voluntários passaram por entrevista inicial e final por meio do questionário de qualidade de vida SF-36. Entremeio a coleta de dados, foram aplicados exercícios fisioterapêuticos durante o período de 4 meses. Após o período pré-determinado os dados foram comparados e analisados de forma quantitativa por meio do Med Calc E e teste T the student. RESULTADOS: Os 15 pacientes em tratamento tinham idade média de 40 anos; 53,3% eram melanoderma; o gênero masculino correspondia a 80%; 60% apresentam contato com zona rural e 80% são de origem da região sudeste. Os 7 pacientes que participaram da intervenção tenderam melhorar os domínios avaliados pelo SF-36 com exceção da vitalidade e aspectos sociais. CONCLUSÕES: O perfil da população deste hospital tem correlação com a literatura pesquisada. De acordo com o SF-36, houve melhora geral da qualidade de vida dos pacientes que aderiram às atividades propostas. Essa pesquisa sugere que a intervenção fisioterapêutica promove diferentes benefícios para os pacientes com pênfigo.

Fogo Selvagem (FS) is a rare autoimmune disease characterized by acantholysis and inflammation of the epidermis. It was evidenced in this disease the increase of pro-inflammatory cytokines levels which can be influenced by physical activities. Kinesiotherapy, as physiotherapeutic interventions, was associated improvement levels of the quality of live, mainly the pain. Understanding the impact of such methodology in immunology of the FS, may constitute an alternative and effective approach. We compare the levels of serum cytokines and chemokines between nine patients with FS submitted to kinesiotherapy for 12 weeks and ten patients not submitted to kinesiotherapy. The kinesiotherapy was composed by self-stretching followed by a resistance training for upper and lower limbs. The protocol was carried out in three sections of eight to ten repetitions with 70% of the maximum load measured by test maximum of ten repetitions. After strengthening period patients performed a passive stretching. The training sessions lasted 50 min and were performed 3 times a week at least 12 weeks. Cytokines and chemokines were assessed in plasma using enzyme-linked immunosorbent assay and/or cytometric bead array. Patients with FS were being kinesiotherapy presented minors levels of interferon-gamma, interleukin (IL)-17, IL-22, and IL-15 when compared to those not submitted to kinesiotherapy. No differences were observed for the detection of the chemokines chemokine ligand (CCL)-2, CCL-3, CCL-5, CCL-11, C-X-C motif chemokine 8 (CXCL-8), and CXCL-10. These results suggest that kinesiotherapy had a positive impact on inflammatory markers that are associated with disease worsening in FS.

To characterize the inflammatory profiles of patients with systemic lupus erythematosus receiving standard treatment compared to healthy controls. Peripheral venous blood was collected from systemic lupus erythematosus patients (n = 14) and controls (n = 18) at enrollment. Blood samples were used for quantification, by flow cytometry, of CD11b (integrin) and Chemokine receptor CXCR2 expression surface antigen in neutrophils and lymphocytes, while cytokines were assayed in serum samples. Purified neutrophils were assayed by their ability to phagocytize human plasma-opsonized zymosan. Patients had a median (interquartile range) disease activity index of 1.0 (0–2.0) characteristic of patients in remission. Interleukin-6 and interleukin-10 serum concentrations were significantly higher in the patient group compared to controls and the phagocytic index of circulating neutrophils was significantly reduced in patients compared to controls. The levels of interleukin-2, interleukin-5, interleukin-8 and tumor necrosis factor alpha did not significantly differ between patients and controls. Flow cytometric analysis revealed that the integrin expression levels were reduced in lymphocytes (but not in neutrophils) obtained from systemic lupus erythematosus patients, while surface expression of the chemokine receptor 2 was similar in both neutrophils and lymphocytes. Systemic lupus erythematosus patients receiving standard treatment presented with elevated systemic levels of interleukin-6 and interleukin-10, reduced neutrophil phagocytic capacity, and reduced lymphocyte expression of integrin even when symptoms were in remission. These alterations to innate immune components may put these individuals at a greater risk for acquiring infections. Caracterizar os perfis inflamatórios de pacientes com lúpus eritematoso sistêmico que estavam recebendo tratamento padrão em comparação com controles saudáveis. Coletou-se o sangue venoso periférico de pacientes com LES (n = 14) e controles (n = 18) no momento da entrada no estudo. As amostras de sangue foram usadas para quantificação, por citometria de fluxo, da expressão dos antígenos de superfície CD11b (integrina) e do receptor de quimiocina CXCR2 em neutrófilos e linfócitos, enquanto as citocinas foram avaliadas em amostras de soro. Avaliou-se a capacidade dos neutrófilos purificados de fagocitar zimosan opsonizado com plasma humano. Os pacientes apresentavam uma pontuação mediana (intervalo interquartil) no índice de atividade da doença de 1,0 (0–2,0), característica de pacientes em remissão. As concentrações séricas de interleucina 6 e interleucina 10 foram significativamente maiores no grupo de pacientes em comparação com os controles; o índice de fagocitose de neutrófilos circulantes estava significativamente reduzido nos pacientes em comparação com os controles. Os níveis de interleucina 2, interleucina 5, interleucina 8 e fator de necrose tumoral alfa não diferiram significativamente entre pacientes e controles. A análise da citometria de fluxo revelou que os níveis de expressão da integrina estavam reduzidos nos linfócitos (mas não nos neutrófilos) obtidos de pacientes com lúpus eritematoso sistêmico, enquanto a expressão do receptor de superfície de quimiocina era semelhante em neutrófilos e linfócitos. Os pacientes com lúpus eritematoso sistêmico recebendo tratamento padrão apresentaram níveis sistêmicos elevados de interleucina 6 e interleucina 10, redução na capacidade fagocítica dos neutrófilos e expressão reduzida da integrina em linfócitos, mesmo quando os sintomas estavam em remissão. Essas alterações nos componentes da imunidade inata podem colocar esses indivíduos em maior risco de adquirir infecções.
