Iloprost: An eicosanoid, derived from the cyclooxygenase pathway of arachidonic acid metabolism. It is a stable and synthetic analog of EPOPROSTENOL, but with a longer half-life than the parent compound. Its actions are similar to prostacyclin. Iloprost produces vasodilation and inhibits platelet aggregation.
iloprost : A carbobicyclic compound that is prostaglandin I2 in which the endocyclic oxygen is replaced by a methylene group and in which the (1E,3S)-3-hydroxyoct-1-en-1-yl side chain is replaced by a (3R)-3-hydroxy-4-methyloct-1-en-6-yn-1-yl group. A synthetic analogue of prostacyclin, it is used as the trometamol salt (generally by intravenous infusion) for the treatment of peripheral vascular disease and pulmonary hypertension.

Iloprost is a long-term effective treatment to achieve healing and prevention in SSc-related DU. Iloprost has prominent anti-edema, anti-inflammatory, vasodilatory, and antiagregant effects.
Iloprost is widely use as a vasodilatator in systemic sclerosis (SSc) Iloprost has experimentally higher anti-edema effect than diclofenac sodium for the conservative treatment of the traumatic soft tissue edema.
Iloprost has transient vasodilatory effects owing to its very short half-time. Iloprost plays an important role in the treatment of Raynaud's phenomenon (RP)
Iloprost-treatment increased hPDLC mineralization and was mediated by PGI2 receptor activation. Iloprost treatment decreases ADMA and SDMA, which are associated with endothelial dysfunctions in patients with Buerger's disease.
Iloprost (ZK36374) protects hamster isolated hepatocytes from the toxic effects of paracetamol and its reactive metabolite N-acetyl-p-benzoquinoneimine. Inhaled iloprost appeared effective and safe in Japanese PAH patients, including ERA- and PDE5-I-treated patients.
Iloprost is an analogue of epoprostenol (prostacyclin; PGI2) and mimics the pharmacodynamic properties of this compound. Under iloprost the absorption of digoxin was delayed by about one hour, but the area under the plasma digoxin concentration curve remained unmodified.
Iloprost combined with low dose tadalafil regimen can effectively reduce PVR, increase 6MWD, and improve cardiopulmonary function in adults CHD patients with severe PAH.
We retrospectively evaluated the clinical records of SSc patients with SSc-related DU and/or severe RP not responsive to CCB. 60 patients (n=44 for DU; n=16 for severe RP) were treated with a monthly 10-hour IV iloprost perfusion.

The 6MWD test is a non-encouraged test, performed in a 30-meter long flat corridor, where the patient is instructed to walk as far as possible, back and forth around two cones during 6 minutes. They can slow down, rest, or stop if needed. This test is used to assess exercise capacity. The test was performed about 30 minutes after study drug administration. Any increase in the walk distance was considered improvement from baseline. (NCT00302211)

This test is used to assess disease severity. Four fucntional classes (FC) are defined from FC I (no limitation of physical activity) to FC IV (inability to carry out any physical activity without symptoms).

Clinical worsening is defined as one of the following: death due to worsening PAH, receipt of lung or heart-lung transplantation, or atrial septostomy, hospitalization for worsening PAH, any early discontinuation from study during the blinded or open-label phase due to worsening PAH, initiation of additional PAH-specific treatment. Due to insufficient data, time could not be assessed accurately and only number of patients with clinical worsening could be reported. (NCT00302211)

"The 6-minute walk test was performed 20-40 minutes after treatment. This was a non-encouraged test (the person conducting the test did not encourage the patient to walk farther or faster) that measured the distance covered over a 6-minute walk.~It was conducted by a trained member of the site staff who was listed on the site's delegation of authority sheet. For patients who had never performed a 6-minute walk test previously, a training test was requested before the qualifying tests for randomization." (NCT00709956)

"The Borg scale is a category-ratio scale, commonly used to evaluate the effects of exercise on dyspnea. The original and modified scales have ratio properties ranging from 0 = nothing at all to 10 = very, very severe, with descriptors from 0 to 10. Descriptors have been modified by others so that 10 has been labeled extremely severe, or the worst possible dyspnea imaginable. Reliability and validity have been reported in a general population and in patients with PAH as well as other respiratory conditions." (NCT00709956)

Melanoma A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world. (Stedman, 25th ed; from Rook et al., Textbook of Dermatology, 4th ed, p2445) | 0 | 2.39 | 2 | 0 |
