Opfindelsen angår en fremgangsmåde til fremstilling af et vævsklæbestof på basis af humane eller animalske proteiner og med et indhold af faktor XIII, fibrinogen og et antibiotikum valgt blandt aminoglycosid, betalactam, polypeptid og tetracyklin.The invention relates to a process for the preparation of a tissue adhesive based on human or animal proteins and containing a factor of XIII, fibrinogen and an antibiotic selected from aminoglycoside, beta-lactam, polypeptide and tetracycline.
55
Fremgangsmåder til fremstilling af et vævsklæbestof med et indhold af fibrinogen og faktor XIII er allerede kendt fra AT-patentskrifterne 359.652 og 359.653, ved hvilke bestemte koncentrationsforhold mellem faktor XIII og fibrinogen 10 og eventuelt albumin indstilles,og præparaterne dybfryses eller lyofiliseres. Disse præparater havde i det væsentlige tilfredsstillende egenskaber, nemlig en høj belastningsevne af klæbningerne og en god resorberbarhed. Det er dog ønskeligt at forbedre disse præparater med hensyn til en 15 antimikrobiel virkning.Methods for preparing a tissue adhesive containing fibrinogen and factor XIII are already known from the AT Patents 359,652 and 359,653, at which certain concentration ratios of factor XIII to fibrinogen 10 and optionally albumin are adjusted and the compositions are deep-frozen or lyophilized. These compositions had essentially satisfactory properties, namely a high load-bearing capacity of the adhesives and a good resorbability. However, it is desirable to improve these compositions for an antimicrobial effect.
Det blev ganske vist allerede i US patentskrift nr. 2.533.004 og af Fel linger og andre i tidsskriftet "Der Tuberkulosearzt" (6/11, 1952) foreslået, at sætte antibiotika til fibrino= 20 genopløsninger og anvende disse som sårklæbestof, men disse opløsninger, der først fremstilles ved sygesengen, resulterer ikke i tilstrækkelig holdbarhed og belastningsevne af det deraf dannede fibrinkoagulat.Admittedly, in U.S. Patent No. 2,533,004 and by Fel linger and others in the journal "Der Tuberculosearzt" (6/11, 1952), it was suggested that antibiotics be used for fibrino = 20 remedies and use them as wound adhesives, but these solutions first prepared by the hospital bed do not result in sufficient durability and load capacity of the resulting fibrin coagulate.
25 Det er endvidere kendt fra et arbejde af Bosch et al,25 It is further known from a work by Bosch et al.
Archiv fur Orthopådische und Unfall-Chirurgie, bind 90 (1977), side 63 til 75, i forbindelse med knogletransplantater at anvende et fibrinklæbesystem til udfyldelse af knogledefekter, hvorved fibrinet dannes direkte på det 30 valgte sted i knoglehulrummet ved tilsætning af thrombin til en fibrinogenopløsning. Efter behov tilsattes også i handelen gående kombinationspræparater af neomycin i pulverform.Archiv fur Orthopådische und Unfall-Chirurgie, Vol. 90 (1977), pages 63 to 75, in connection with bone grafts, to use a fibrin adhesive system for filling bone defects, whereby the fibrin is formed directly at the selected site in the bone cavity by the addition of thrombin to a fibrinogen solution. . As needed, commercially available powder formulations of neomycin were also added.

Ifølge egne forsøg blev det fastslået, at de beskrevne og 5 kendte vævsklæbestoffer, som indeholder fibrinogen, faktor XIII og et antibiotikum, ikke har den ønskede kombination af egenskaber, nemlig en høj belastningsevne af klæbningerne og en antimikrobiel virkning, men at der indtræder en uheldig vekselvirkning mellem antibiotika og faktor XIII, 10 med den virkning, at fibrinogenets tværbindingsevne falder stærkt, og koagulationsevnen påvirkes ugunstigt. Som følge deraf bevirker det en forringet styrke og adhæsionsevne af klæbemidlet til sår- eller vævsfladerne.According to their own experiments, it was determined that the described and known tissue adhesives containing fibrinogen, factor XIII and an antibiotic do not have the desired combination of properties, namely a high load-bearing capacity and an antimicrobial effect, but that an adverse effect occurs. interaction between antibiotics and factor XIII, 10 with the effect that the fibrinogen's cross-linking ability is greatly decreased and its clotting ability is adversely affected. As a result, it impairs the strength and adhesiveness of the adhesive to the wound or tissue surfaces.
15 En yderligere ulempe ved de kendte præparater består i at afgivelsen af antibiotikum til vævet foregår for hurtigt, således at antibiotikumretardationen ikke er tilstrækkelig til at virke i længere tid og til opnåelse af en høj afgivelse af virksomt stof.A further disadvantage of the known compositions is that the delivery of antibiotic to the tissue takes place too quickly, so that the antibiotic retardation is not sufficient to last for a long time and to obtain a high release of active substance.

Ifølge en foretrukken udførelsesform, ved hvilken den fibrino-genholdige blodplasmafraktion vaskes med en pufferopløsning, gennemføres vaskeprocessen indtil opnåelse af en faktor XIII-koncentration på 200 enheder faktor XIII/g fibrinogen, hvoref-5 ter faktor XIII tilsættes i en mængde på mindst 300 enheder/g fibrinogen i form af et koncentrat eller lyofilisat.According to a preferred embodiment, in which the fibrinogen-containing blood plasma fraction is washed with a buffer solution, the washing process is performed until a factor XIII concentration of 200 units of factor XIII / g of fibrinogen is carried out, after which factor XIII is added in an amount of at least 300 units. / g fibrinogen in the form of a concentrate or lyophilisate.
Fordelagtigt er der i et dybfrosset vævsklæbestof indeholdt faktor XIII i en mængde på mindst 40 enheder/ml. I tilfælde af 10 et lyofiliseret vævsklæbestof skal der været indeholdt mindst 33 vægt% fibrinogen, idet faktor XIII er til stede i en mængde på mindst 170 enheder/g lyofilisat.Advantageously, in a frozen tissue adhesive, factor XIII is contained in an amount of at least 40 units / ml. In the case of a lyophilized tissue adhesive, at least 33% by weight fibrinogen must be contained, with factor XIII present in an amount of at least 170 units / g of lyophilisate.
Som plasmininhibitor eller plasminogen-aktivator-inhibitor kan 15 der hensigtsmæssigt anvendes en valgt blandt aprotinin, <X2-an-tiplasmin, o^-makroglobulin, aj-antitrypsin, e-aminocapronsyre og tranexamsyre< Vævsklæbestoffet foreligger fordelagtigt som et tokomponent- 20 præparat, hvor faktor XIII, fibrinogen og plasmin-inhibitoren eller plasminogen-aktivator-inhibitoren er indeholdt i den første komponent, medens antibiotiket, thrombin og divalent calcium er indeholdt i den anden komponent.Conveniently, as a plasmin inhibitor or plasminogen activator inhibitor, one selected from aprotinin, <X2-antiplasmin,? -Macroglobulin, α-antitrypsin, α-aminocaproic acid and tranexamic acid <The tissue adhesive may advantageously be present as wherein the factor XIII, fibrinogen and the plasmin inhibitor or plasminogen activator inhibitor are contained in the first component, while the antibiotic, thrombin and divalent calcium are contained in the second component.
25 Fortrinsvis anvendes antibiotiket i form af et tungt opløseligt derivat. En variant af denne udførelsesform kan bestå i, at der foruden det tungt opløselige derivat også anvendes et let opløseligt, eventuelt fordelt i vævsklæbestoffets to komponenter. Denne udførelsesform har den fordel, at det let op-30 løselige derivat hurtigt afgives og sikrer en høj begyndelsesvirkning, hvorimod det tungt opløselige begrunder en langvarig vi rkni ng.Preferably, the antibiotic is used in the form of a heavily soluble derivative. A variant of this embodiment may consist in that, in addition to the heavily soluble derivative, a slightly soluble, optionally distributed in the two components of the tissue adhesive is also used. This embodiment has the advantage that the readily soluble derivative is rapidly released and ensures a high initial effect, whereas the heavily soluble justifies a long-term effect.
