Abstract

The present invention is to provide an agent for preventing and/or treating multiple organ failure comprising Tumor cytotoxic factor-II (TCF-II) or Hepatocyte growth factor (HGF) as an effective ingredient.

Description

TECHNICAL FIELD

[0001] The present invention relates to a novel agent for preventing and/or treating multiple organ failure.

[0002] Development from burn, disseminated intravascular coagulation (DIC), circulatory failure, hemorrhagic shock, infectious disease, acute pancreatitis, ischemic disorder, hepatorenal syndrome, gastrointestinal hemorrhage, nutritional metabolic failure, terminal cancer, acquired immunodeficiency syndrome (AIDS), deterioration of systemic conditions due to radiation affection and cachexia etc. to multiple organ failure can be prevented or treated by the present invention.

BACKGROUND TECHNOLOGY

[0003] Onset or exacerbation of multiple organ failure can be classified into the following 3 categories with respect to mechanism: (1) Parallel induction of several organ disorders due to the same factor, (2) Induction of a specific organ dysfunction due to disorder of an organ; and (3) Participation of an iatrogenic factor. Excessive insults due to severe trauma or major surgeries, infectious diseases, shock etc. directly or through various kinds of mediator participate in the onset or deterioration of multiple organ failure by mechanism (1). In the case of multiple organ failure accompanied with organ disorder due to trauma or primary hepatic insufficiency, participation of mechanism (2) through organ correlation mechanism will largely contribute to the onset or deterioration thereof. By mechanism (3), medical care carried out during intensive care or care to correspond with an organ disorder may result in the other organ disorder. In patients, these 3 mechanisms participate to the development or deterioration of disorder in a complexed manner. The prognosis of patients of multiple organ failure is generally very poor and, in fact, the survival rate is low as 20-30% in spite of a wide variety of corresponding treatment.

DISCLOSURE OF THE PRESENT INVENTION

[0004] Considering the above situations, the present inventors eagerly investigated to look for an agent for preventing and/or treating multiple organ failure and found that multiple organ failure caused by burn, disseminated intravascular coagulation (DIC), circulatory failure, hemorrhagic shock, infectious disease, acute pancreatitis, ischemic disorder, hepatorenal syndrome, gastrointestinal hemorrhage, nutritional metabolic failure, terminal cancer, acquired immunodeficiency syndrome (AIDS), deterioration of systemic conditions due to radiation affection and cachexia etc. can be prevented or treated with tumor cytotoxic factor-II (TCF-II) which is a glycoprotein derived from human fibroblastor hepatocyte growth factor (HGF) which is a proteineous substance derived from blood of a patient with fulminating hepatitis. Accordingly, an object of the present invention is to provide an agent for preventing and/or treating multiple organ failure comprising TCF-II or HGF as an effective ingredient.

BEST MODE OF EMBODIMENT FOR THE PRACTICE OF THE PRESENT INVENTION

[0017] The agent of the present invention for preventing and/or treating multiple organ * failure can be useful for preventing and/or treating the development from bum, disseminated intravascular coagulation (DIC), circulatory failure, hemorrhagic shock, infectious disease, acute pancreatitis ischemic disorder, hepatorenal syndrome, gastrointestinal hemorrhage, nutritional metabolic failure, terminal cancer, acquired immunodeficiency syndrome (AIDS), deterioration of systemic conditions due to radiation affection and cachexia etc. These kinds of multiple organ failure will develop by accompanying with burn, surgical operation, administration of chemical substances (including medicine), radiation or other disorder.

[0018] TCF-II which is an effective ingredient of the present invention was found by the present inventors and a known glycoprotein derived from human fibroblast having the following characteristics:

1)	Molecular weight(by SDS
	electrophoresis)
	under non-reducing conditions:	78,000 ± 2,000 or 74,000
		± 2,000
	under reducing conditions:	52,000 ± 2,000 (common b and A)
		30,000 ± 2,000 (b and B)
		26,000 ± 2,000 (b and C)
2)	Isoelectric point:	7.4-8.6

[0019] The above TCF-II can be obtained by adsorbing culture medium of human fibroblast on an ion exchange column then purifying the elute by affinity chromatography (WO 90/10651) or by genetic engineering manipulation (WO 92/01053). TCF-II which is an effective ingredient of the present invention can be derived from fibroblast or produced by genetic engineering manipulation using microbial or other cell as based on the genetic sequence described in patent application WO 90/10651. Further, TCF-II obtained by genetic engineering manipulation described in WO 92/01053 can be also used. TCF-II with different carbohydrate chain or without carbohydrate chain due to difference of host cell or microbial organism can be also used. However, since carbohydrate chain correlate to metabolic rate in a biological body, one with carbohydrate chain can be preferably used. TCF-II obtained by these methods can be concentrated and purified by usual isolation and purification method. For example, precipitation with organic solvent, salting-out, gel permeation, affinity chromatography using monoclonal antibody, electrophoresis can be exemplified. Purification by affinity chromatography using monoclonal antibody can be carried out using monoclonal antibody described in a Japanese unexamined laid open patent application No. 97(1993). The obtained TCF-II can be lyophilized or kept frozen.

[0020] Substance having the same activity as TCF-II can be used as the agent of the present invention. For example, hepatocyte growth factor (HGF; Japanese unexamined laid-open patent application No.22526 (1988)) which is formed by insertion of 5 amino acids into TCF-II protein or purified Scattered Factor (SF; Gherardi and Stocker, Nature, 346,228 (1990)) can be exemplified.

[0021] HGF which is an effective ingredient has an activity proliferating hepatic sell, was isolated from the blood of a patient with fulminating hepatitis and is unknown protein with the following characteristics (Japanese patent No.2564486):

[0022] 1) Molecular weight (SDS-PAGE); under non-reducing conditions;

[0023] 76,000-92,000;

[0024] 2) The activity described above was not deactivated by heating at 56° C. for 15 minutes, but it was deactivated by heating at 80° C. for 10 minutes;

[0025] 3) Digestion with tripsin or chymotripsin deactivated the above activity; and

[0026] 4) It show affinity with heparin.

[0027] HGF can be obtained by heating plasma at 56° C. for about 15 minutes, taking precipitated fraction at the ammonium sulfate concentration of 1.1-1.2 M, followed by purification using gel permeation and ion exchange chromatography such as DEAE anion exchange chromatography. Alternatively, HGF can be obtained by genetic engineering manipulation using HGF cDNA (BRRC 163, 967-973, 1989, or Japanese unexamined laid open patent application No.97(1993)).

[0028] The agent of the present invention for preventing and/or treating multiple organ failure can be administered intravenously, intramuscularly or subcutaneously. These pharmaceutical preparation can be prepared according to a known pharmaceutical preparation method and, if necessary, pH conditioner, buffer and/or stabilizer can be added thereto. Dose of the present agent can be different depending on the severness of symptom, health conditions, age, body weight of a patient. Though the dose will not be restricted, pharmaceutical preparation comprising 0.6 mg-600 mg-TCF-II/day, preferably 6 mg-60 mg-TCF-II/day, for one adult person can be administered at once or more. The dose of HGF can be nearly the same as that of TCF-II.

[0029] Administration as described above can prevent multiple organ failure caused by various kinds of mechanism described before or alleviate symptom thereof.

EXAMPLE

[0030] The present invention will be described below in detail by exemplifying examples. However, these are only examples and the present invention will not limited thereby.

Example 1

[0031] Purification of TCF-II

[0032] According to a method described in WO 90/10651 and a method of Higashio et al (Higashio; K et al, B.B.R.C., vol.170, pp397-404 (1990)), cell was cultured and purified TCF-II was obtained. That is, 3×106 human fibroblast IMR-90 (ATCC CCL 186) cells were placed in a roller bottle containing 100 ml DM medium including 5% calf fetal serum and cultured by rotating it at the rate of 0.5-2 rpm for 7 days. When the total number of cell reached 1×107 cells were deprived from the wall by tripsin digestion and collected at the bottom of bottle. And 100 g of ceramic with the size of 5-9 mesh (Toshiba Ceramic) was sterilized and put therein, which was cultured for 24 hours. After then, 500 ml of the above culture medium was added thereto and the culture was continued. The total volume of culture medium was recovered every 7-10 days and fresh medium was supplemented. Production was kept for 2 months like this and 4 liters of culture medium was recovered per a roller bottle. Specific activity of TCF-U in culture medium obtained as above was 32 μg/ml. Culture medium (750 L) was concentrated by ultrafiltration using membrane filter (MW 6,000 cut; Amicon) and purified by 5-steps chromatography, that is, CM-Sephadex C-50 (Pharmacia), Con-A Sepharose(Pharmacia), Mono S column Pharmacia), Heparin-Sepharose (Pharmacia) to yield purified TCF-IL This TCF-II had the same molecular weight and isoelectric point as described before.
