ABSTRACT This study purposed to compare responses of segmented neutrophils, monocytes, lymphocytes, and T lymphocyte Clusters of Differentiation 4 and 8 to blood flow restriction training in HIV patients. Two HIV patients participated in the study, one patient had a sedentary lifestyle, and the other was physically active. HIV-infected female patients performed a blood flow restriction training session consisting of two exercises: flat bench press and knee extension. Blood (6 mL) was collected for analysis prior to training, immediately after training, and 30 minutes after. After blood flow restriction training, percentage changes in the number of leukocytes were observed in both patients. Monocytes showed different responses in the two patients: a decrease in monocyte count was seen in the physically active, and an increase was observed in the sedentary lifestyle. Lymphocytes showed a higher increase in the physically active than in the sedentary lifestyle. There was an increase in the CD4+ / CD8+ T lymphocyte ratio in both patients. It was concluded blood flow restriction promoted acute inflammation after training, shown by changes in immune cell counts. These changes did not promote immunosuppression; instead, an increase in CD4+ / CD8+ T lymphocyte ratio was observed; and HIV-infected came similar results.

OBJETIVOS: Avaliar por meio de critérios clínicos, a proporção de pacientes com esclerose múltipla (EM) responsivos aos imunomoduladores (RI) e não responsivos aos imunomoduladores (NRI) e avaliar se dados clínicos e epidemiológicos são distintos nesses dois grupos. MÉTODOS: Os pacientes foram avaliados quanto à taxa de surtos por ano no período antes e após o início do tratamento. Diversas características clínicas e epidemiológicas foram comparadas entre os pacientes RI e NRI. DISCUSSÃO E CONCLUSÃO: Em nossa população, 31,4% dos pacientes não responderam ao tratamento com os imunomoduladores. Os principais preditores de resposta aos imunomoduladores foram: diagnóstico e início precoce da terapia e elevada taxa de surtos anual antes do tratamento. Como existem várias opções medicamentosas disponíveis para o tratamento da EM, a identificação de candidatos potenciais para abordagens terapêuticas diferentes representa o ponto crucial para otimizar a evolução dos pacientes com essa doença.

OBJECTIVES: To determine, based on clinical criteria, the proportion of multiple sclerosis (MS) patients responsive to immunomodulators (RI) and nonresponsive to immunomodulators (NRI), and to ascertain whether clinical and epidemiological data differs between RI and NRI patient groups. METHODS: Patients were assessed on rate of exarcerbations per year, for the period before and after commencement of treatment. The RI and NRI groups were compared for several clinical and epidemiological characteristics. DISCUSSION AND CONCLUSION: A total of 31.4% of the patients were nonresponders to the immunomodulatory treatment. The main predictors of immunomodulatory response were early diagnostic and commencement of therapy and high rate of annual exacerbations prior to treatment. Given the arsenal of medication options available for MS management, screening potential candidates for different therapeutic approaches are critical to optimize evolution of patients with the disease.
