Definitions
- Alprostadil Prostaglandin El
- the invention relates to the use of alprostadil for the manufacture of a medicament for angioneogenesis.
- Cardiomyopathy is a disease that causes enlargement of the heart muscle and weakness of the heart muscle.
- the cardiac muscle weakness leads to a reduced pumping function and ejection action of the heart.
- the pathogenesis of dilative cardiomyopathy is still unknown.
- Ischemic cardiomypathy can be attributed to myocardial infarction (e), since the dead areas of the heart muscle are replaced by connective tissue.
- e myocardial infarction
- this cardiac muscle replacement from connective tissue cannot perform cardiac functions.
- cardiac muscle function is reduced and water accumulates in the lungs and lower extremities. The consequences are severe shortness of breath, resilience and fatigue.
- Alprostadil is a medication that was originally used because of its good vasodilator effect in the treatment of newborns with (anatomical) cardio-pulmonary malformations. Another restricted use of Alprostadil (PGEl) is chronic erectile dysfunction.
- EP 0 153 858 A2 describes the use of prostaglandins (including prostaglandin El) for the treatment of multiple organ damage, acute respiratory distress syndrome (ARDS; shock lung), shock trauma or sepsis.
- ARDS acute respiratory distress syndrome
- shock lung shock trauma or sepsis.
- Rabinowitz et al. (Am.j. Ther. 4 (11/12) (1997), pp.353-358) describe the hemodynamic effect of prostaglandin El on patients with coronary artery disease with stable and unstable angina pectoris, who require an intervention with PTCA (cardiac catheter Balloon dilatation) or bypass surgery or had an acute myocardial infarction. Furthermore, an increase in skin temperature after the use of prostaglandin El in patients with peripheral arterial occlusive disease is found.
- PTCA cardiac catheter Balloon dilatation
- the object of the present invention was to provide a new use of alprostadil (prostaglandin El) which is not based on its vasodilatory effect.
- the alprostadil therapy used according to the invention obviously leads to: a) new capillary formation and improvement of the blood flow to the organ, b) Reduction of the pathological degree of fibrosis, c) Formation of tunnel capillaries, d) Regression of muscle hypertrophy in chronic heart failure, e) Neovascularization, which is associated with increased VEGF production, whereby other growth factors such as TFGb, PDGF, FGF are also likely to be involved are; f) increasing the heart index in chronic heart failure; g) increasing the ejection action in the event of chronic heart failure; h) flooding of pulmonary edema in chronic heart failure; i) lowering the increased pressures in the small circulation (pulmonary circulation) in chronic heart failure; j) stabilization of blood pressure in chronic heart failure; k) improvement in breathlessness and decrease in NYHA stage; m) reduction of muscle hypertrophy in CMP and hypertension-related cardiomyopathy.
- PGE1 is preferably administered by (intravenous) infusion.
- the application can also be preferably intracoronary.
- Epicardial application in the pericardium, local application with the help of application balloons, application in coronary veins with the help of retrograde perfusion techniques and transmyocardial application with the help of laser, high-frequency ablation and / or injection needles can also be indicated.
- Fig. 3 MIB-1 positive endothelial cells in Subepicardium (Subepi), Myocardium (Myocard) and Subendocardium (Subendo) in alprostadil (PGE 1) -treated patients compared to Control group;
- 6 representative images of PGE1-treated patients (6A: CD-34-positive capillaries; 6B: vwF-positive capillaries, 6C: MIB-1-positive capillaries, 6d: VEGF-positive capillaries (the arrows mark positive capillaries in each case; .6A-C are taken with 100X magnification; Fig. ⁇ D with 400X magnification));
- FIG. 7 shows a Sirius red staining (fibrosis content) of a patient after PGEl therapy (FIG. 7A) and a patient without PGEl therapy (FIG. 7B);
- Fig.8 CD34 (treated (Fig.8A) and untreated (Fig. ⁇ B)), vwF (treated (Fig.8C) and untreated (Fig.8D), VEGF (treated (Fig.8E) and untreated (Fig.8F )) as well as MIB-1 (treated (Fig. ⁇ G) and untreated (Fig. ⁇ H).
- HTX heart translation
- PGE 1 Alprostadil
- ACE inhibitors angiotensin converting enzyme antagonists
- diuretics digitalis.
- b The hemodynamics of the patients showed a low cardiac index ( ⁇ 2.5 L / min / m2) and a higher PCWP (pulmonory capillary wedge pressure)> 20 mm HG).
- PCWP pulsemonory capillary wedge pressure
- the infusion therapy was carried out with continuous measurement of the hemodynamic parameters. There was a significant improvement in the hemodynamic parameters compared to the initial values with simultaneous improvement of the clinical symptoms.
- alprostadil (PGEl) infusion therapy was used in patients with end-stage insufficiency in terms of adjuvant therapy up to HTX.
- this group of patients was diagnosed with a significant improvement in clinical condition with increased sputum and cardiac output combined with a reduction in NYHA stage and pathological pressures in the pulmonary circulation.
- the alprostadil (PGEl) infusions were carried out via a central right heart catheter (Hickman catheter) with an initial dose of 2.5 ng / kg / min, which was then increased to the maximum tolerated dose (MTD).
- MTD was the dose at which one of the following side effects occurred: muscle pain, bone pain, drop in blood pressure, nausea, vomiting, diarrhea, headache or other side effects.
- the hemodynamic parameters were documented under the MTD (29 ⁇ 1 ng / kg / min). The MTD was halved in the following 12 hours and after hemodynamic stabilization, therapy with a portable pump was continued at home.
- Each explanted heart was divided into three equal pieces, namely the tip, middle and basal part.
- the incision was made transmurally through the middle part of the left ventricle.
- the tissue for immunohistochemical analysis was preserved in formaldehyde immediately after removal in accordance with the usual method.
- the capillary density was determined separately in the subepicardium, myocardium and the subendocardium.
- the determination of the capillary density l, mm 2 was separated on the basis of anti-CD34, von Willebrand factor (vWf), vascular-endothelial-growth-factor (VEGF), anti-Ki 67 (MIB 1) and Sirius Rot, immunohistochemically stained paraffin sections carried out.
- vWf von Willebrand factor
- VEGF vascular-endothelial-growth-factor
- MIB 1 anti-Ki 67
- Sirius Rot immunohistochemically stained paraffin sections carried out.
- the capillary density in the subepicardium, myocardium and subendocardium of transmural sections was quantified and compared. Patients who received an alprostadil (PGE 1) infusion had significantly more capillaries (p ⁇ 0.001) per mm 2 than the control group.
- the capillary density in the subepicardium, myocardium and subendocardium from the control group was 608.56 ⁇ 91.32 capillaries / mm 2 (sEpi), 542.44 ⁇ 197.20 capillaries / mm 2 (sEndo), and 452.22 ⁇ 101.99 Capillaries / mm 2 (Myo) in the three transmural areas.
- CD 34 endothelial cell marker
- CD 34 is expressed by all endothelial cells in normal tissue. CD 34 is also used for the detection of endothelium or cells. Patients after alprostadil (PGE 1) therapy had significantly more anti-CD34 reactive endothelium (Fig. 1) than the control group (subepicardium: 599.22 ⁇ 107.17 mm 2 compared to 322.89 ⁇ 160.64 mm 2 - Cells, p ⁇ 0.001; myocardium: 482.11 ⁇ 79.86 mm 2 vs.
- PGE 1 alprostadil
- MIB-1 proliferation marker
- MIB-1 anti-Ki67
- MIB-1 is an antibody that only reacts with cells that are not in the GO phase of the cell cycle and is commonly used as a mitosis or proliferation marker. It shows a characteristic reaction in mitotic cells.
- VEGF is described as a specific growth factor for endothelial cells.
- Alprostadil (PGE 1) -treated patients showed significantly more VEGF-positive capillaries / mm 2 than the control group (Fig. 4) in all three examined section levels (subepicardium: 101.2 + 5.5 / mm 2 compared to 38.1 ⁇ 7.2) -VEGF positive cells / mm 2 , p ⁇ 0.0001; myocardium 76.2 ⁇ 4.9 / mm 2 versus 20.6 ⁇ 4.9 / mm 2 , p ⁇ 0.0001; subendocardium: 89.1 ⁇ 5, 7 / mm 2 versus 27.8 ⁇ 5.1 / mm 2 , p ⁇ 0.0001). The results are also shown in Figures 6D, 8E and 8F.
- Muscle number / mm 2 with percentage muscle / mm 2 was determined in PGEl-treated patients and compared with untreated patients and healthy controls. The results are shown in the table below.
