Ceftaroline fosamil achieved high clinical cure and microbiological response rates in patients hospitalized with CAP of PORT risk class III or IV. Ceftaroline fosamil was well tolerated, with a safety profile that is similar to that of ceftriaxone and other cephalosporins. Ceftaroline fosamil is a promising agent for the treatment of CAP.

Although more common in women, SSc appears as strikingly more severe in men. Our results obtained through the largest worldwide database demonstrate a higher risk of severe cardiovascular involvement in men. These results raise the point of including sex in the management and the decision-making process.

The aim of our study was to investigate and characterize regulatory T cells (Treg) in peripheral blood of patients with connective tissue diseases (Systemic lupus erythematosus, systemic sclerosis, Sjögren's syndrome, poly- and dermatomyositis) as compared with blood from healthy controls. Treg cells were quantified and phenotypically characterized by flow cytometry while the expression level of Foxp3 mRNA was evaluated by real time PCR. A reduced percentage of peripheral blood Treg cells was found in patients than in controls, irrespective of the type of connective tissue disease. Treg cells, especially those expressing one of the phenotypical markers, seemed to differ not only between patients and healthy controls but also among types of diseases. Additionally, the presence of autoantibodies as well as disease activity appeared to be correlated with particular Treg cell populations, especially those expressing one of the examined phenotypical markers. Correlations with therapy suggested that glucocorticoids plus antimalarial or other immunosuppressor drugs diminished the percentage of Treg cells, especially of those with memory phenotype. These findings indicated dysregulations at the level of Treg cells and suggested an involvement of these cells in the pathology of connective tissue diseases. Moreover, our data are in agreement with the suggestion that Treg cells could be therapeutic targets for some autoimmune diseases.

Background: Tigecycline, an expanded broad-spectrum glycylcycline, exhibits in vitro activity against many common pathogens associated with community-acquired pneumonia (CAP), as well as penetration into lung tissues that suggests effectiveness in hospitalized CAP patients. The aim of the present study was to compare the efficacy and safety of intravenous (IV) tigecycline with IV levofloxacin in hospitalized adults with CAP.

Background: Non‐insulin dependent diabetes mellitus (NIDDM) represents an independent risk factor for cardiovascular diseases (CVD), being characterized by a continnous low‐grade inflammation and endothelial activation state. Plasma platelet ‐ activating factor ‐ acetylhydrolases (PAF‐AHs) are a subgroup of Ca2+ ‐independent phospholipase A2 family (also known as lipoprotein‐associated phospholipases A2) that hydrolyze and inactivate the lipid mediator platelet‐activating factor (PAF) and/or oxidized phospholipids. This enzyme is considered to play an important role in inflammatory diseases and atherosclerosis. The present study aims to investigate the relations between the levels of PAF‐AH activity and LDL‐cholesterol/HDL‐cholesterol (LDL‐ch/HDL‐ch) ratio in NIDDM patients as compared to controls. Methods: serum PAF‐AH activity was measured in 50 patients with dyslipidemia, in 50 NIDDM patients and in 50 controls (normal lipid and glucose levels). Total cholesterol, LDL‐ch, HDL‐ch, triglyceride and blood glucose were determined in all subjects. Results: All NIDDM patients display hiperlipidemia, with increased LDL‐ch and triglyceride levels. There is a significant correlation between LDL‐ch levels (especially LDL‐ch / HDL‐ch ratio) and PAF‐AH activity in dyslipidemic and NIDDM patients. Conclusion: Diabetic and dyslipidemic patients have an increased plasma PAF‐AH activity correlated with their LDL‐ch levels and mainly with LDL‐ch / HDL‐ch ratio. Plasma PAF‐AH high levels appear to be important as a risk marker for endothelial dysfunction in patients with NIDDM.
