Definitions
- Fibronectin solution suitable for human use and process for its preparation
- the invention relates to a fibronectin solution suitable for use on humans and to a process for its preparation.
- Fibronectin is a high molecular weight glycoprotein which consists of two subunits, each with a molecular weight of approximately 220,000, and which occurs in soluble form in the plasma in a concentration of approximately 0.3 mg / ml. Fibronectin is found in insoluble form in the connective tissue and associated with the basal membrane. Soluble fibro nectin occurs with collagen . Heparin, fibrin and staphylococci interact, whereby it has a function in mediating the adhesion of cells, such as thrombocytes, the organization of fibrin clots and the formation of connective tissue, but in particular also as one of the main opsonizing factors has the phagocytosis function of the reticuloendothelial system.
- Fibronectin is cross-linked with fibrin by activated factor XIII and causes the fibrin clot to solidify, which in this context attracts fibroblasts. According to its incorporation into the fibrin clot, the serum concentration of fibrin is about 20-50% lower than that of the plasma. Clinically of particular importance is the function of fibronectin as opsonin, and there is strong evidence that is necessary for normal functioning of the reticulo-endothelial system in the spleen, liver and "bone marrow fibronectin. Thus one finds in animal studies that the phagocytic capacity by artificial depletion of
- Fibronectin is massively suppressed. Furthermore, fibro nectin mediates the binding of fibrin to macrophages and increases the phagocytosis of streptococci. A reduced level of fibronectin is found in patients after major operations or trauma and in advanced malignancies. diseases. The reduction in fibronectin could also be related to the . The development of the "shock lung" in sepsis is related. In patients in intensive care units, it was found that higher plasma fibronectin levels could be correlated with a significantly lower mortality during induction and that patients with fibronectin levels that dropped below 0.195 mg / ml during the stay had a 65% higher mortality than those patients in whom the fibronectin level did not drop below 0.195 mg / ml during the stay.
- Fibronectin is in fresh plasma, fresh frozen Plas ⁇ ma containing antihemophilic plasma and cryoprecipitate and was Wandt therapeutically ange ⁇ in the form of cryoprecipitate, with dramatic improvements in some of 'patient th after trauma, particularly in terms of cardio-powder-monalen function found were.
- these administration forms of fibronectin have the disadvantage of the relatively large volume and the fact that these administration forms cannot be treated by heat treatment analogously to the hepatitis-safe albumin.
- the object of the invention is to provide a fibronectin preparation in the form of a solution which is virus-safe and can therefore be administered without restriction.
- a fibronectin solution was created according to the invention which contains virus-safe fibronectin due to heat inactivation.
- the process according to the invention for the preparation of this solution consists in starting material containing fibronectin in the form of cryoprecipitate, fresh frozen plasma, outdated plasma, low cryoprecipitate plasma or fibronectin-containing, human plasma fractions, for example with organic precipitants, such as polyethylene glycol, alcohols , Ether, or with inorganic precipitating agents, such as ammonium sulfate, sodium sulfate, sodium chloride, precipitated plasma, or chromatographically produced fibronectin-containing plasma fractions, such as, for example, ion exchange chromatography or affinity chromatography on gelatin, heparin or arginine-sepharose, subjected to fractionation stages,
- a native Fibronek preparation contains at least one stabilizer sator adds at least a heat treatment
- the supernatant containing fibronectin obtained is concentrated and freed of electrolytes and low molecular weight peptides and that the fibronectin solution thus obtained is added further solvents such as albumin, plasma protein solution processed into an intravenously administrable preparation for humans.
- the fibronectin solution according to the invention is a heat-activated fibronectin preparation which contains, for example, 2 mg / ml fibronectin in its dimeric form, dissolved in a 5% strength plasma protein solution. Despite heat inactivation, this preparation has its full function in terms of binding to collagen and fibrin, mediating the adhesion of macrophages and increasing the phagocytosis rate of macrophages.
- Both the adhesion of macrophages and the phagocytosis rate are influenced in a dose-dependent manner by the preparation according to the invention, an increase in adhesion of about 90% and an increase in the phagocytosis rate of more than 70% being obtained at a concentration of 100 ⁇ g / ml.
- this preparation was tolerated in five patients at the highest tested concentration of 1 ml / kg with an infusion rate of 2 ml / min without side effects.
- EXAMPLE Human plasma from healthy donors is diluted with purified water to a protein concentration of 3.8% and brought to a saturation of 25-28% with saturated ammonium sulfate solution.
- the pH is 6.3 or 8.0.
- the ammonium sulfate precipitate is dissolved at room temperature in sodium citrate solution, 0.0 ⁇ mol / liter, and the same amount of saturated sodium chloride solution is added at pH 7.6-8.0.
- the resulting precipitation is again at room temperature tur dissolved in 0.06 molar sodium citrate solution, stabilized with 0.02 mol / liter sodium caprylate and 0.02 mol / liter sodium N-acetyl-DL-tryptophanate at a pH of 7.6 - 8.0. 50 g of glucose per liter of solution are then added. This is followed by a 10 hour pasteurization at a temperature of 57- ⁇ O ° C.
- the clear supernatant containing fibronectin is diafiltered in order to remove the electrolytes and peptides below 20,000 daltons.
- the fibro nectin is then concentrated using the same ultrafilter.
- the fibronectin concentrate is mixed with plasma protein solution and stabilized with 0.03 mol / liter sodium caprylate and with 0.01 mol / liter sodium N-acetyl-DL-tryptophanate.
- the isotonicity of the solution is achieved by adding sodium chloride (Na content 130-160 mmol / liter).
- the pH is adjusted to 7.0 + _ 0.3.
- Fibronectin-containing plasma protein solutions according to the invention can have, for example, the following compositions, the individual constituents being given in g / 1:
