Filter by:Sepsis is the most common cause of childhood death worldwide. Millions of children survive, but are left with impaired health. Sepsis-related Acute Kidney Injury (sAKI) is increasingly recognized as a significant factor associated with long-term mortality among different patient populations. Renal dysfunction and subsequent chronic kidney disease is implicated in the development of hypertension and cardiovascular disease. The investigators overall hypothesis is that, in the pediatric population, sepsis-related AKI will have unrecognized, long-term consequences with regard to kidney function, endothelial function, blood pressure control, and overall health.

The investigators aim to correlate noninvasive pulmonary artery systolic pressure (PASP) measurements obtained with and without echocardiographic contrast (Optison) during transthoracic echocardiography (TTE) with those obtained invasively and simultaneously during right heart catheterization, as the gold standard.
The purpose of this study is to evaluate the non-inferiority clinical efficacy of two different drug associations in the essential hypertension control.

High blood pressure, also referred to as hypertension, affects about 65 million people in the United States alone. Approximately 25 percent of people with hypertension cannot control their high blood pressure, despite the use of multiple medications. Recently, new evidence has demonstrated that the carotid body (CB) plays a role in essential refractory hypertension, possibly due to a deregulated, enhanced activity of this organ. Animal studies showed that CB de-afferentiation, through carotid sinus nerve denervation, leads to a long-term stable drop in blood pressure in spontaneously hypertensive rats. De-afferentiation may be performed either by injecting local anesthetics or by electrical stimulation. Both techniques are daily used in the operating theater to anesthetize nerves for a wide range of surgical procedures. We hypothesize that blocking CB with local anesthetics will result in a drop of the blood pressure in refractory hypertensive patients. We also want to test the idea that stimulating the CB with an electrical current will mislead the CB and will also result in a drop of the blood pressure.
The objective of the study is to investigate effects of inorganic sodium nitrite on the cardiometabolic and hormonal disturbances observed in a targeted population of overweight/obese adults with metabolic syndrome and hypertension, at risk for insulin resistance and endothelial dysfunction.
Trial Rationale/ Justification To assess efficacy and safety of inhaled Iloprost in treatment naïve patients with left heart failure and pulmonary hypertension, who are on the waiting list for orthotopic heart transplantation. As patients often show increasing hemodynamic values while waiting for a donor organ, the transplantation becomes infeasible at the time of identification of an appropriate donor organ when reaching the exclusion limits. Therefore, there is a high need of improvement and stabilisation of the patients' hemodynamic values as PVR, PAP and TPG. In a retrospective, non-controlled study inhaled Iloprost has already shown a beneficial effect on the hemodynamics as reduction of PVR, TPG and CI (Schulz 2010). Treatment with inhaled Iloprost could stabilize the hemodynamics and prevent the patients from being classified as ineligible by the time an appropriate donor organ is identified. However, the adverse event profile regarding frequency, time-dependency has to be further validated to show safety and tolerability of inhaled Iloprost in this indication. All patients can be transferred to a long-term medically supervised observation period with inhaled Iloprost therapy.
The purpose of this study is to determine whether postpartum administration of furosemide to women with antepartum hypertensive disorders (gestational hypertension, preeclampsia) or elevated blood pressure in the first 24 hours following delivery reduces severe postpartum hypertension.
The EAGLE study is a Phase 3, open-label, multi-center, two-part, single-arm study of GeNOsyl(R) delivery system(s) to evaluate if inhaled nitric oxide-induced vasodilation predicts successful wean from parenteral prostacyclin (PGI) in subjects with World Health Organization (WHO) Group 1 pulmonary arterial hypertension (PAH) undergoing a medically necessary right heart catheterization (RHC). All subjects enrolled in the study will undergo an attempt to wean from parenteral PGI per standard of care.
