Hepatitis C virus (HCV) mainly targets the liver but can also induce extrahepatic manifestations. The kidney may be impacted via an immune mediated mechanism or a cytopathic effect. HCV patients are clearly at a greater risk of chronic kidney disease (CKD) than uninfected patients are, and the presence of CKD increases mortality. Interferon-based therapies and ribavirin are difficult to manage and are poorly effective in end-stage renal disease and hemodialysis. These patients should be given priority treatment with new direct anti-viral agents (DAAs) while avoiding peginterferon and ribavirin...

Copayments for prescriptions may increase morbidity and mortality via reductions in adherence to medications. Relevant data can inform policy to minimise such unintended effects. We explored the generalisability of evidence for copayments by comparing two international copayment polices, one in Massachusetts and one in Ireland, to assess whether effects on medication adherence were comparable. We used national prescription data for public health insurance programmes in Ireland and Medicaid data in the U.S. New users of oral anti-hypertensive, anti-hyperlipidaemic and diabetic drugs were included (total n=14,259 in U...

Chronic pulmonary hypertension (PH) is associated with right ventricular failure and high mortality regardless of the underlying disease. Currently, therapies can improve clinical outcomes in specific subsets of patients, but have little impact on the progression of pulmonary vascular remodeling. Upon new advances in vector development and delivery techniques, gene therapy is a novel strategy in this field with the potential of overcoming the main limitations of approved drug therapies: modulation of novel anti-remodeling targets and selective pulmonary vasculature targeting with minimal systemic effects...

Cerebral venous thrombosis (CVT) has an incidence of 1.32/100,000/years in high-income countries, and higher in middle- and low-income countries. CVT is more frequent in infants and children young adults and females, especially during pregnancy/puerperium. CVT are now being diagnosed with increasing frequency because of the increased awareness and higher use of magnetic resonance imaging (MR) for investigating patients with acute and subacute headaches and new onset seizures. CVT rarely present as a stroke syndrome...

REVIEW
Xu Cao, Jin-Song Bian
Hydrogen sulfide has gained recognition as the third gaseous signaling molecule after nitric oxide and carbon monoxide. This review surveys the emerging role of H2S in mammalian renal system, with emphasis on both renal physiology and diseases. H2S is produced redundantly by four pathways in kidney, indicating the abundance of this gaseous molecule in the organ. In physiological conditions, H2S was found to regulate the excretory function of the kidney possibly by the inhibitory effect on sodium transporters on renal tubular cells...

BACKGROUND: Intracerebral hemorrhage (ICH) is one of the most common forms of cerebral hemorrhage, the morbidity and death of ICH is high worldwide. ICH can be spontaneous or caused by hypertension, coagulopathy, angiopathy, head trauma, bleeding disorders, tumors, or drug usage. ICH is the most serious and least treatable form of hemorrhagic stroke, with rapidly increasing hematoma size and often resulting in significant brain injury and long term neurological deficits. Surgical hematoma evacuation remains controversial...

Hypertension (HTN) is the most prevalent modifiable risk for cardiovascular disease (CVD) and disorders directly influencing CVD (i.e. obesity, diabetes, chronic kidney disease, obstructive sleep apnea, etc.). About one billion people worldwide have HTN, with American adults having 90% lifetime risk of developing HTN. Despite aggressive campaign for lifestyle changes and advances in drug therapy, HTN remains an immense health, emotional, and economic challenge. This is due, in part, to the fact that ∼50% of HTN patients' blood pressure remains uncontrolled and ∼20% of HTN patients are resistant to or require > antihypertensive drugs...

OBJECTIVE: Recently several studies reported that anti-hypertensive drugs were associated with development of new-onset diabetes mellitus (NODM). However, data on the relationship between detailed prescription types and long-term incidence of NODM are still limited in Asian patients (pts). DESIGN AND METHOD: A total of 3,208 consecutive hypertension pts prescribed with calcium channel blockers (CCB) were enrolled with the exclusion of diabetic pts. Pts were divided into two groups according to the additional prescription of renin angiotensin system (RAS) blockers; 1) the CCB group (n = 1,987) and 2) CCB + RAS group (n = 1,221)...

Pathophysiological mechanisms contributing to hypertension include endothelial dysfunction and vascular ignalling. These changes are initially adaptive but chronically become maladaptive leading to vascular damage and loss of function. Common to these processes are changes in the characteristics of vascular cells to a pro-infl ammatory, vasoconstrictory and proliferative phenotype, infl uenced by activation of the RAS and oxidative stress. Increased ROS production and decreased cellular antioxidant defense mechanisms, contribute to oxidative stress, which infl uences redox-sensitive Ang II ignalling that promotes vascular injury in hypertension...

OBJECTIVE: There is some debate as to optimal BP goals with antihypertensive treatment derived mostly in post-hoc analysis of large trials. Because there was limited number of subjects and outcomes within the larger study which may cloud the analytical accuracy of the findings. We suggest a new method to estimate the J-curve. DESIGN AND METHOD: Felodipine Event Reduction (FEVER) study randomized 9711 Chinese hypertensive patients to more or less intense anti-hypertensive treatment with 159,844 BP measurements...

Pathophysiological mechanisms contributing to hypertension include injury to small arteries, characterised by endothelial dysfunction, vascular remodeling, fibrosis and inflammation, (so called hypertensive vascular phenotype). These changes are initially adaptive but in the long term become maladaptive leading to vascular damage and loss of function, particularly important in small resistance arteries, critically involved in the regulation of peripheral vascular resistance and consequently in blood pressure control...

Hypertensive patients have greater chances of such cardiovascular events as stroke, coronary heart disease, heart or renal failure, peripheral artery disease, and dementia. It is also well recognized that diabetes increases the cardiovascular risks in concert with hypertension. Therefore, main goals for an innovation of anti-hypertensive therapy would be to achieve further risk reduction by targeting the functional, metabolic, and structural alterations associated with hypertension. Professors Dzau and Braunwald et al proposed the concept of "the cardiovascular disease continuum" in 1991, and that hypertension may trigger the chain of events, leading to end-stage heart disease; however, this concept was quite new at that time, and there was some discussion whether "the cardiovascular disease continuum" is true or not...

Hypertension is the main risk factor for morbidity and mortality in the world. In Sub-Saharan Africa, hypertension, previously almost unknown, is now a major risk factor. A paper recently published showed that mean systolic blood pressure is higher in all regions of Africa compared with other parts of the world, and, most important and contrary to what is happening in the rest of the world, it is increasing in the last years. Another important issue that characterises hypertension in Africa is its extremely low level of awareness and consequently low level of control...

Molecular Hybridization is an approach in rational drug design where new chemical entities are obtained by combining two or more pharmacophoric units from different bioactive compounds into a single molecule. Through this approach, medicinal chemists hope that the new hybrid derivative presents: better affinity and efficacy when compared to the parent drugs; a modified selectivity profile with improvement over pharmacokinetic and pharmacodynamic restrictions; dual or multiple modes of action; reduction of undesirable side effects; decreases in drug-drug interactions; reduced emergence or spread of drug resistance in microorganisms and protozoans; and lower cost...

In 2015, the international guidelines for diagnosis and treatment of pulmonary hypertension (PH) were updated. Group 3 of the current classification includes PH associated with chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD), other pulmonary diseases with restrictive and obstructive pattern, sleep-disordered breathing, alveolar hypoventilation disorders, chronic exposure to high altitude, and developmental lung diseases [1]. PH associated with COPD and ILD is common but difficult to manage, as no long-term randomised controlled trial (RCT) has been conducted with specific pulmonary arterial hypertension (PAH) drugs in PH associated with COPD, and the one recent RCT in PH associated with ILD had to be stopped early due to a possible increased risk of death and side effects in the treatment group...
