Treatment of pulmonary hypertension in pregnancy with a prostacyclin analogue-iloprost and/or calcium channel antagonists appears to improve outcomes and survival. These medications could have been administered to the patient and the response monitored. If the patient did not respond to therapy, this patient may have had either a referral to or transfer to another high risk center with more experience in this type of pregnant patient. There is no literature to support termination of pregnancy improving maternal survival outcomes in these patients, even though termination is recommended by all obstetrical textbooks...

AIM: Insufficient oxygen supply to organs and tissues due to reduced arterial or venous blood flow results in ischaemia, during which, although ATP production stops, AMP and adenosine continue to be produced from ATP. The fate of irisin, which causes the production of heat instead of ATP during ischaemia, is unknown. Iloprost and sildenafil are two pharmaceutical agents that mediate the resumption of reperfusion (blood supply) via vasodilatation during ischaemic conditions. Our study aimed to explore the effects of iloprost and sildenafil on irisin levels in the heart, liver and kidney tissues and whether these pharmaceutical agents had any impact on serum irisin and nitric oxide levels in rats with induced experimental myocardial ischaemia...

INTRODUCTION: Osteonecrosis is an ischemic pathologic process associated with a number of conditions affecting a range of age groups. The problem faced in the management of osteonecrosis is whether conservative treatment is a viable and effective option for patients. In this systematic review, we investigated the efficacy of various nonoperative treatment modalities for hip and knee osteonecrosis, including pharmacological management and biophysical modalities. METHODS: We identified 16 studies based on electronic searches through the PubMed, Embase, CINAHL Plus, and Cochrane databases from January 2001 to November 2015...

Prostacyclin (prostaglandin I2, PGI2) over-production in FVB/N mice prevents the formation of carcinogen and tobacco smoke induced adenomas, and administration of the oral prostacyclin analog iloprost to wild type mice also prevented carcinogen-induced mouse lung adenoma formation. Former smokers taking oral iloprost showed improved bronchial dysplasia histology compared to placebo. Next generation oral prostacyclin analogues, like treprostinil, were developed for treatment of pulmonary arterial hypertension (PAH)...

BACKGROUND AND OBJECTIVE: Involvement of pulmonary vascular remodelling is a characteristic sign in COPD. Vascular mediators such as vascular endothelial growth factor (VEGF) and prostacyclin may regulate fibroblast activity. The objective was to study the synthesis of VEGF and interactions with prostacyclin and transforming growth factor (TGF)-β1 in lung fibroblasts from patients with COPD and healthy control subjects. To further explore the autocrine role of synthesized VEGF on fibroblast activity, studies were performed in human lung fibroblasts (HFL-1)...

Buerger's disease is characterized by recurring progressive inflammation and occlusions in small and medium arteries and veins of the limbs. Its cause is unknown, but it is most common in young men with a history of tobacco use. It is responsible for ischemic ulcers and extreme pain in the hands and feet. In many cases, notably in patients with the most severe presentations, there is no possibility of improving the condition with surgery (limb revascularisation), and therefore, alternative therapies (e.g. sympathectomy) is used...

During cardiac operations, weaning from cardiopulmonary bypass (CPB) may prove challenging as a result of superimposed acute right ventricular dysfunction in the setting of elevated pulmonary vascular resistance (PVR). The aim of this study was to retrospectively evaluate the effect of inhaled milrinone versus inhaled iloprost in patients with persistent pulmonary hypertension following discontinuation of CPB. Eighteen patients with elevated PVR post-bypass were administered inhaled milrinone at a cumulative dose of 50 μg kg(-1)...

BACKGROUND/AIM: The protective effects of prostaglandin (PG) analogs on ischemia-reperfusion (I/R) have been well documented; however, comparative studies are lacking. The aim of the present study was to determine whether iloprost or alprostadil is more effective in preventing muscle I/R injury. MATERIALS AND METHODS: Thirty-two rats were divided into four groups (n = 8): sham, control, IL (I/R + iloprost), and AL (I/R + alprostadil). I/R was induced by a tourniquet in the hindlimb for 3 h/3 h...

Some biomarkers play important roles in the endothelial dysfunction of patients with pulmonary arterial hypertension (PAH), including nitric oxide (NO), endothelin-1 (ET-1), asymmetric dimethylarginine (ADMA), galectin-3 (Gal-3), B-type natriuretic peptide (BNP), and uric acid (UA). However, studies on these biomarkers in pulmonary artery blood in congenital heart disease-PAH (CHD-PAH) and the effect of iloprost on the regulation of biomarkers are lacking. This study investigated potential CHD-PAH biomarkers and their association with the severity of disease...

Prostacyclins are vasodilatory agents used in the treatment of pulmonary arterial hypertension. The direct effects of prostacyclins on right heart function are still not clarified. The aim of this study was to investigate the possible direct inotropic properties of clinical available prostacyclin mimetics in the normal and the pressure-overloaded human right atrium. Trabeculae from the right atrium were collected during surgery from chronic thromboembolic pulmonary hypertension (CTEPH) patients with pressure-overloaded right hearts, undergoing pulmonary thromboendarterectomy (n = 10) and from patients with normal right hearts operated by valve replacement or coronary bypass surgery (n = 9)...

Right ventricular failure (RVF) after cardiac transplant (CTX) or implantation of a continuous-flow left ventricular assist device (CF-LVAD) is associated with significant postoperative morbidity and mortality. A variety of modalities have been used to treat postoperative RVF, including management of volume status, intravenous inotropes and vasodilators, and right-sided mechanical support. Inhaled vasodilator agents are a unique treatment option aimed at minimizing systemic absorption by delivering therapy directly to the pulmonary vasculature...

With disease progression, avascular necrosis (AVN) of the femoral head may lead to a collapse of the articular surface. The exact pathophysiology of AVN remains unclear, although several conditions are known that can result in spontaneous cell death, leading to a reduction of trabecular bone and the development of AVN. Hip AVN treatment is stage-dependent in which two main stages of the disease can be distinguished: pre-collapse (ARCO 0-II) and post-collapse stage (ARCO III-IV, crescent sign). In the pre-collapse phase, core decompression (CD), with or without the addition of bone marrow (e...

Pulmonary hypertension may coexist with certain diseases in neonates. Iloprost inhalation is one of the treatments which cause selective pulmonary vasodilatation. Inhalation is not an easy way of drug administration in mechanically ventilated infants; as some exhibit desaturations during inhalation. Moreover, inhalation of drug requires cessation of mechanical ventilation, if patient is on high frequency oscillatory ventilation. We presented two patients with pulmonary hypertension; term baby with congenital diaphragmatic hernia and preterm baby with respiratory distress syndrome; who had iloprost instillation during mechanical ventilation treatment...
