Multicenter Study
Early Lupus Project - A multicentre Italian study on systemic lupus erythematosus of recent onset.
Systemic lupus erythematosus (SLE) is an autoimmune disease with a high degree of variability at onset that is problematic for a correct and prompt diagnosis. We undertook this project with the purpose of collecting an inception cohort of Italian patients with recent-onset SLE, in order to obtain information on the main clinical and serological characteristics at the beginning of the disease. In this first report we describe the characteristics of this cohort at study entry. ⋯ In this paper we describe the main clinical and serological characteristics of an Italian inception cohort of patients with recent-onset SLE. At disease onset, mucocutaneous manifestations, arthritis and haematologic manifestations were the most frequent symptoms; ANA, anti-dsDNA and complement reduction were the most frequent laboratory findings. Our data confirm that the diagnosis of SLE is a challenging one, and that SLE is a severe disease even at onset, since the majority of patients require at least a hospitalization before the diagnosis.

Case Reports
A case of catastrophic antiphospholipid syndrome: first report with advanced cardiac imaging using MRI.
This present case pertains to a 48-year-old woman with a history of antiphospholipid syndrome, who presented with progressive fatigue, generalized weakness, and orthopnea acutely. She had a prior diagnosis of antiphospholipid syndrome with recurrent deep vein thromboses (DVTs) and repeated demonstration of lupus anticoagulants. She presented in cardiogenic shock with markedly elevated troponin and global myocardial dysfunction on echocardiography, and cardiac catheterization revealed minimal disease. ⋯ Despite echocardiographic evidence of myocardial dysfunction in such patients, MRIs of CAPS have not previously been reported. This case highlights the utility in assessing the involvement of the myocardium by the microangiopathic process with MRI. Because the diagnosis of CAPS requires involvement in multiple organ systems, cardiac MRI is likely an underused tool that not only reaffirms the pathophysiology of CAPS, but could also clue clinicians in to the possibility of a diffuse thrombotic process.

Review Meta Analysis
Association of the interleukin-6 polymorphisms with systemic lupus erythematosus: a meta-analysis.
Interleukin (IL)-6, an important proinflammatory cytokine, plays a potential pathological role in systemic lupus erythematosus (SLE). Studies on the relationship of IL-6 gene polymorphisms with SLE are inconclusive. The aim of this study was to estimate the relationship more precisely. ⋯ This meta-analysis provides evidence of the association between the IL-6 polymorphism and the risk of SLE, hinting that the IL-6-174 G/C and IL-6-572 G/C polymorphisms may play a role in SLE susceptibility.

The aim of this study was to determine whether the functional CD40 rs4810485 G/T polymorphism is associated with susceptibility to rheumatoid arthritis (RA) or with susceptibility to systemic lupus erythematosus (SLE). ⋯ Our meta-analyses confirm that the CD40 rs4810485 G/T polymorphism is associated with susceptibility to RA and SLE in Europeans.
