Long-term safety and efficacy of etanercept in the treatment of ankylosing spondylitis
[EN] To date, anti-tumor necrosis factor alfa (anti-TNF-α) therapy is the only alternative
to nonsteroidal anti-inflammatory drugs for the treatment of ankylosing spondylitis. Etanercept
is a soluble TNF receptor, with a mode of action and pharmacokinetics different to those of
antibodies and distinctive efficacy and safety. Etanercept has demonstrated efficacy in the treatment
of ankylosing spondylitis, with or without radiographic sacroiliitis, and other manifestations
of the disease, including peripheral arthritis, enthesitis, and psoriasis. Etanercept is not
efficacious in inflammatory bowel disease, and its efficacy in the treatment of uveitis appears
to be lower than that of other anti-TNF drugs. Studies of etanercept confirmed regression of
bone edema on magnetic resonance imaging of the spine and sacroiliac joint, but failed to
reduce radiographic progression, as do the other anti-TNF drugs. It seems that a proportion
of patients remain in disease remission when the etanercept dose is reduced or administration
intervals are extended. Etanercept is generally well tolerated with an acceptable safety profile
in the treatment of ankylosing spondylitis. The most common adverse effect of etanercept treatment
is injection site reactions, which are generally self-limiting. Reactivation of tuberculosis,
reactivation of hepatitis B virus infection, congestive heart failure, demyelinating neurologic
disorders, hematologic disorders like aplastic anemia and pancytopenia, vasculitis, immunogenicity,
and exacerbation or induction of psoriasis are class effects of all the anti-TNF drugs,
and have been seen in patients with ankylosing spondylitis. However, etanercept is less likely
to induce reactivation of tuberculosis than the other anti-TNF drugs and it has been suggested
that etanercept might be less immunogenic, especially in ankylosing spondylitis. Acute uveitis,
Crohn’s disease, and sarcoidosis are other adverse events that have been rarely associated with
etanercept therapy in patients with ankylosing spondylitis.Senabre-Gallego, JM.; Santos-Ramírez, C.; Santos-Soler, G.; Salas-Heredia, E.; Sánchez Barrioluengo, M.; Barber, X.; Rosas, J. (2013).

Cardiovascular events in Systemic Lupus Erythematosus: a nationwide study in Spain from the RELESSER Registry
This article estimates the frequency of cardiovascular (CV) events that occurred after diagnosis in a large Spanish cohort of patients with systemic lupus erythematosus (SLE) and investigates the main risk factors for atherosclerosis. RELESSER is a nationwide multicenter, hospital-based registry of SLE patients. This is a cross-sectional study. Demographic and clinical variables, the presence of traditional risk factors, and CV events were collected. A CV event was defined as a myocardial infarction, angina, stroke, and/or peripheral artery disease. Multiple logistic regression analysis was performed to investigate the possible risk factors for atherosclerosis. From 2011 to 2012, 3658 SLE patients were enrolled. Of these, 374 (10.9%) patients suffered at least a CV event. In 269 (7.4%) patients, the CV events occurred after SLE diagnosis (86.2% women, median [interquartile range] age 54.9 years [43.2-66.1], and SLE duration of 212.0 months [120.8-289.0]). Strokes (5.7%) were the most frequent CV event, followed by ischemic heart disease (3.8%) and peripheral artery disease (2.2%). Multivariate analysis identified age (odds ratio [95% confidence interval], 1.03 [1.02-1.04]), hypertension (1.71 [1.20-2.44]), smoking (1.48 [1.06-2.07]), diabetes (2.2 [1.32-3.74]), dyslipidemia (2.18 [1.54-3.09]), neurolupus (2.42 [1.56-3.75]), valvulopathy (2.44 [1.34-4.26]), serositis (1.54 [1.09-2.18]), antiphospholipid antibodies (1.57 [1.13-2.17]), low complement (1.81 [1.12-2.93]), and azathioprine (1.47 [1.04-2.07]) as risk factors for CV events. We have confirmed that SLE patients suffer a high prevalence of premature CV disease. Both traditional and nontraditional risk factors contribute to this higher prevalence. Although it needs to be verified with future studies, our study also shows-for the first time-an association between diabetes and CV events in SLE patients
Planck intermediate results. XXXII. The relative orientation between the magnetic field and structures traced by interstellar dust
The role of the magnetic field in the formation of the filamentary structures observed in the interstellar medium (ISM) is a debated topic owing to the paucity of relevant observations needed to test existing models. The Planck all-sky maps of linearly polarized emission from dust at 353 GHz provide the required combination of imaging and statistics to study the correlation between the structures of the Galactic magnetic field and of interstellar matter over the whole sky, both in the diffuse ISM and in molecular clouds. The data reveal that structures, or ridges, in the intensity map have counterparts in the Stokes Q and/or U maps. We focus our study on structures at intermediate and high Galactic latitudes, which cover two orders of magnitude in column density, from 1020 to 1022 cm2. We measure the magnetic field orientation on the plane of the sky from the polarization data, and present an algorithm to estimate the orientation of the ridges from the dust intensity map. We use analytical models to account for projection effects. Comparing polarization angles on and o the structures, we estimate the mean ratio between the strengths of the turbulent and mean components of the magnetic field to be between 0.6 and 1.0, with a preferred value of 0.8. We find that the ridges are usually aligned with the magnetic field measured on the structures. This statistical trend becomes more striking for increasing polarization fraction and decreasing column density. There is no alignment for the highest column density ridges. We interpret the increase in alignment with polarization fraction as a consequence of projection effects. We present maps to show that the decrease in alignment for high column density is not due to a loss of correlation between the distribution of matter and the geometry of the magnetic field. In molecular complexes, we also observe structures perpendicular to the magnetic field, which, statistically, cannot be accounted for by projection effects. This first statistical study of the relative orientation between the matter structures and the magnetic field in the ISM points out that, at the angular scales probed by Planck, the field geometry projected on the plane of the sky is correlated with the distribution of matter. In the diffuse ISM, the structures of matter are usually aligned with the magnetic field, while perpendicular structures appear in molecular clouds. We discuss our results in the context of models and MHD simulations, which attempt to describe the respective roles of turbulence, magnetic field, and self-gravity in the formation of structures in the magnetized ISM
