The Role of Lipid-Lowering Therapy in Post-Stroke Patients: Update and Recommendations.

PURPOSE OF REVIEW: Stroke is the second leading cause of death and disability-adjusted life years worldwide, and the global lifetime risk of stroke is rising. Moreover, patients with a prior stroke are at high risk of recurrent events. We aimed at reviewing the evidence supporting aggressive secondary prevention strategies for lipid-lowering treatment in this population. RECENT FINDINGS: Statins are the key players in such aggressive management; however, stroke survivors remain at significant residual risk suggesting the need for both better implementation of statin use as well as additional lipid lowering therapies. Newer drugs have become available and represent important tools in the management of patients with prior ischemic stroke. The role of lipid lowering treatment in hemorrhagic stroke is more controversial, given epidemiological data linking low lipid levels with increased risk of first and recurrent events. Aggressive secondary prevention strategies, including lipid lowering treatments, have proven to mitigate the risk of recurrent events in post-stroke patients. The tools available for treating such high-risk population have expanded beyond statins, and clinicians should familiarize themselves with them.

Evaluation of Cardiovascular Toxicity Associated with Treatments Containing Proteasome Inhibitors in Multiple Myeloma Therapy.

INTRODUCTION: Recently new treatment options have substantially increased survival for patients with relapsed and/or refractory multiple myeloma (RRMM). Among these, proteasome inhibitors (PI), such as bortezomib and carfilzomib, offer high response rate and prolonged survival. These agents are generally well tolerated but demonstrated a significant cardiovascular toxicity, mostly for regimen containing carfilzomib. AIM: To assess the cardiovascular damage in patients treated with PI for RRMM. METHODS: 28 consecutive subjects treated with PI for RRMM were evaluated and compared with a population of 22 control (Con) subjects, matched for age, sex and mean 24 h blood pressure (24hMBP). All individuals underwent trans-thoracic echocardiography, ambulatory blood pressure monitoring and pulse wave velocity (PVW) study. RESULTS: PI patients did not have significant differences in blood pressure load and PWV compared to controls. Among echocardiographic parameters, the global longitudinal strain (GLS) was significantly decreased in PI subjects (p = 0.02). The GLS was significantly lower also considering only patients treated with carfilzomib. Moreover, among carfilzomib patients, we found increase values of left ventricle mass indexed by BSA (LVMi; p = 0.047). After correction for age, sex, BSA, 24hMBP and morphological and functional parameters of LV, treatment with PI and carfilzomib were significantly associated with GLS (p = 0.01; p = 0.036, respectively). CONCLUSIONS: PI treatment is associated with subclinical LV dysfunction in patients with RRMM compared to controls, as demonstrated by lower GLS values. These results are confirmed also considering patients treated with carfilzomib. Moreover, in this subgroup of patients, the LVMi is also increased, suggesting higher cardiotoxicity with this treatment.

[Non-immunological therapy in nephropathies leading to chronic renal failure and in post-transplant chronic renal dysfunction]. / La terapia non immunologica delle nefropatie con insufficienza renale cronica e della disfunzione cronica da trapianto.

With its aging population, the Western world is experiencing a significant increase in the prevalence of chronic kidney disease, which has actually been defined as ''pandemic''. The high mortality and comorbidity, especially in terms of cardiovascular disease, have led to a significant increase in hospitalizations and rising public health expenditure, setting a trend that will become unsustainable in the next decades, even in the most developed countries. These epidemiological data have underlined the need for prevention campaigns and urged researchers and clinicians to develop new and more specific treatments able to slow down the progression of chronic kidney disease towards dialysis. To obtain such results, a deeper understanding of the pathogenetic mechanisms of nephropathy progression is mandatory. Once sclerosis is established and the initial pathogenetic noxa, whether or not involving the glomeruli, has been extinguished, the sclerotic progression of different nephropathies follows a standard pathway, irrespective of the initial cause. The achievement of an effective therapy for this condition, in native kidneys as well as transplanted organs, is the third-millennium challenge for nephrologists. In this review we will first describe the main risk factors and pathogenetic mechanisms involved in nephropathy progression and then discuss the results obtained with drugs that basic research has identified as potentially useful in experimental animal models as well as rigorous clinical trials.
