Abstract
Introduction: COPD (chronic obstructive pulmonary disease) presents a low degree of systemic inflammation responsible for the disease’s extra pulmonary consequences. Its inflammatory profile can be altered by acute exercise. However, acute effects of a sub maximum test, capable of reproducing activities of daily living (ADL) in sedentary COPD individuals, are not well-known
Objective: To evaluate if the six-minute walk test (6MWT) is capable of altering interleukin-6 (IL-6) blood levels, tumoral necrosis factor alfa (TNF-α) and hypersensitive C reactive protein (hs-CRP) in relation to the basal level of COPD individuals.
Methods: 21 individuals with moderate and severe COPD and 8 healthy individuals, with no history of smoking, sedentary, matched by age were assessed regarding plasma levels of IL-6, TNF-α and hs-CRP before and right after a 6MWT. They also did spirometry and body composition analysis.
Results: 6MWT did not provoke significant alteration in IL-6 levels in COPD individuals (pre=4.53 ± 9.0 pg/ml vs. post=7.14 ± 11.31 pg/ml, p=0.11), whereas in healthy individuals this increase was significant (pre=1.56 ± 6.45 pg/ml vs. post=4.37 ± 8.0 pg/ml, p<0.01). COPD individuals present higher hs-CRP blood levels when compared to healthy subjects both in rest (8.15 ± 9.68 pg/ml vs. 2.60 ± 1.88 pg/ml, p=0.02), and after exercise (8.18 ± 9.08 pg/ml vs. 2.62 ± 1.85 pg/ml, p=0.02. TNF-α did not present difference between groups during rest (COPD=2.13 ± 1.03 pg/ml vs. healthy=2.00 ± 0.59 pg/ml, p>0.05) as well as after 6MWT (COPD=2.48 ± 1.92 pg/ml vs. healthy=1.89 ± 0.69 pg/ml, p>0.05), and their intragroup focus was not affected by the effort (p>0.05).
Conclusions: In COPD patients, 6MWT does not induce acute inflammatory response of IL-6 at the same proportion of that of healthy subjects. Hs-CRP’s and TNFα’s response to 6MWT was similar between groups. COPD patients presented higher concentrations of hs-CRP than healthy individuals.

Artigos 2017: Identification of specific antibodies against the Ag85C-MPT51-HspX fusion protein (CMX) for serological screening of tuberculosis in endemic area.

Abstract
OBJECTIVES:
Development of new tools for rapid and accurate diagnosis of tuberculosis (TB) is considered a strategy for controlling the disease. The recombinant CMX fusion protein is composed of immunodominant epitopes of the Ag85C (Rv0129c), MPT51 (Rv3803c) and the entire HspX (Rv2031c) proteins from Mycobacterium tuberculosis H37Rv (Mtb). The aim of this study was to evaluate the applicability of a test using the CMX protein in individuals suspected of TB.
METHODS:
Indirect ELISA was used to measure serum anti-CMX IgM and IgG in individuals with pulmonary TB.
RESULTS:
Patients with pulmonary TB had higher titers of IgM (OD = 0.502 ± 0.281) than healthy controls (OD = 0.200 ± 0.125). The cutoff for IgM-ELISA was determined using ROC curve analyzes (AUC = 0.868) with a sensitivity of 80.1% and a specificity of 78.2%. Patients with pulmonary TB also had higher titers of IgG (OD = 0.525 ± 0.391) than healthy controls (OD = 0.215 ± 0.077). The cutoff for IgG-ELISA was determined using ROC curve analyzes (AUC = 0.864) with a sensitivity of 81.7% and a specificity of 74.7%.
CONCLUSION:
The results suggest that the recombinant protein CMX can be used in a serological test to complement the screening of individuals suspected of having active pulmonary TB.
