RESUMEN
The objective of the study was to investigate the association between IL-8 and other biomarkers of endothelial dysfunction (MCP-1, V-CAM, I-CAM) and the disease activity scores in a sample of 54 patients with ankylosing spondylitis (AS) without use of biological agents. Fifty-four AS patients without treatment with anti-TNFs agents between 18 and 80 years old, who met modified New York criteria and at the same time the axial ASAS criteria, were evaluated using an epidemiological questionnaire that included among others clinical data, BASDAI, BASFI, ASQoL, ASDAS and plasma levels of CRP, ESR, MCP-1, IL-8, ICAM-1 and VCAM-1. IL-8 varied in proportion to disease activity rates (BASDAI and ASDAS) p < 0.05, being strongly correlated with the disease activity. The levels of adhesion molecules I-CAM and VCAM, as described in other studies, were positively correlated with predisposing factors for cardiovascular disease. IL-8 has shown to be strongly correlated with clinical markers of disease activity and inflammatory activity and may be an additional variable to the overall assessment of the activity of the AS.

In March 2009 was the beginning of an epidemic flue caused by avian influenza A virus H1N1. The disease varies from mild to serious and fatal cases. There are many hypotheses explaining why this virus infection would be fatal. One of these is the impaired immune response of the infected patient. The use of tumor necrosis factor-alpha inhibitors may cause decreased immune response and greater susceptibility to infections. We presented a case of a patient using adalimumab that have developed H1N1 without complications. This is the first case of H1N1 in a patient using adalimumab reported in Brazil. We discuss the possibility that anti-TNF may not predisposes to a serious form of the disease or fatal complications.
