ReviewAlogliptin; a review of a new dipeptidyl peptidase-4 (DPP-4) inhibitor for the treatment of type 2 diabetes mellitus.
Dipeptidyl peptidase-4 inhibitors (DPP-4 inhibitors) are effective and safe oral incretin-based antihyperglycemic drugs. In preclinical studies, DPP-4 inhibitors have demonstrated cardiovascular benefits, independent of glycemic control, in patients with type-2 diabetes mellitus. ⋯ Studies have shown that alogliptinis non-inferior to comparator drugs among newly diagnosed type 2 diabetes mellitus patients. Alogliptin can effectively be used as a single agent or as an add-on drug in combination with other glucose lowering drugs with favorable outcomes on glycemic control and HbA1C levels.

ReviewAugmentation therapy with alpha1-antitrypsin: novel perspectives.
SERPINA1, α-antitrypsin (AAT) is an acute phase protein, a member of the serpin (serine protease inhibitor) super family and one of the most abundant protease inhibitors in the circulation. The clinical importance of AAT is emphasized in persons with inherited AAT deficiency who exhibit high risk of developing early onset pulmonary emphysema, neonatal hepatitis, liver cirrhosis, which may appear at any age, and in rare cases panniculitis and vasculitis. The most common and severe AAT deficiency is associated with the Z (Glu342 to Lys) mutation. ⋯ Given the importance of the protease/antiprotease imbalance in causing emphysema, augmentation of circulating AAT is used as a specific therapy for patients with AAT deficiency-related emphysema but not for those with liver diseases. According to the novel findings, therapy with AAT possesses antiinflammatory and immuno-modulatory effects across a broad spectrum of experimental models of systemic and local inflammation. Hence, in this article we will discuss putative new directions for the clinical use of therapy with AAT.

Infective endocarditis (IE) is a lethal disease if not promptly treated with antibiotics, either in association with surgery or not. The incidence of disease has not decreased over the last decades due to the change of risk conditions. Complications of IE may involve cardiac structures when the infection spreads within the heart, or extra cardiac ones when the cause is usually from embolic origin; they may also be due to medical treatment or to the septic condition itself. ⋯ Echocardiography, mainly from transesophageal (TEE) approach, has significantly improved the evaluation of IE allowing to detect the specific signs of the disease as vegetations, abscesses, valve insufficiency, prosthetic valve dehiscence, fistulas. In our 3rd referral Hospital (Lancisi Heart Hospital, Ancona, Italy) we performed a follow-up (mean 8.26 years) of 15 patients with periannular complications associated with IE. The long term follow-up showed low mortality rate, high incidence of reintervention, improved New York Heart Association (NYHA) class in survivors and no changes of the lesions at the echocardiographic examination, suggesting that periannular complications have not significantly influenced the overall survival in our patients at the follow-up.

ReviewThe important new drug target in cardiovascular medicine--the vascular glycocalyx.
The process of atherothrombosis is known to involve endothelial pathology (first drug target), plaque formation (second drug target) and thrombosis (third drug target). However it has recently been postulated that, even before endothelial pathology occurs, the very first step in the process of atherothrombosis is dysfunction of the arterial glycocalyx that lies between the endothelial cells and the blood [1]. So there are really four drug targets, and perhaps the arterial glycocalyx will become the most important for future early prevention of people at risk. ⋯ Attempts are being made to explore the possibility of drug-induced reversal of hyperglycaemia-induced glycocalyx dysfunction. Progress is, however, dependent on grants being made available for work with the essential large animal (pig) experimental model for testing glycocalyx function. Such grants have hitherto not been sufficiently forthcoming, and this needs to be brought urgently to the attention of the pharmaceutical industry.
