Definitions
- the present invention relates to a remedy for endotoxemia and multi-organ dysfunction induced thereby.
- Endotoxin is a lipopolysaccharide that constitutes the cell membrane of Gram-negative bacteria, and its physiological activities include fever, lowering blood pressure, lowering platelets, coagulation in blood vessels, increasing capillary permeability, and activating traps.
- Various effects are known. For this reason, infection with Gram-negative bacteria causes sepsis, or abnormal growth of Gram-negative bacteria in the large intestine increases the endotoxin concentration in the blood, causing endotoxemia.
- various disorders caused by endotoxinemia not only cause severe shock death but also develop into multiple organ dysfunction. Examples of multiple organ failure include cirrhosis, fulminant hepatitis, acute renal failure, lung failure, gastrointestinal bleeding,
- antibiotics have been administered for the purpose of suppressing the growth of Gram-negative labor, which is a source of endotoxin.
- high-dose administration of antibiotics causes drug-resistant bacteria such as MRSA to appear, making treatment more difficult, and endotoxin blood due to endotoxin release from gram-negative bacteria killed by antibiotics. Because of the exacerbation of the disease, the development of therapeutic agents other than antibiotics has been desired.
- the present invention solves the above-mentioned conventional problems, and does not cause drug-resistant bacteria as in the case of using antibiotics, and exhibits excellent therapeutic effects against various gram-negative bacteria.
- the purpose of the present invention is to provide a therapeutic agent for endotoxinemia and multi-organ dysfunction induced by the endotoxinemia, which is safe for the human body and can be treated continuously.
- the present inventors have focused on diseases induced by the physiological activity of endotoxin and searched for a drug that reduces the expression of the physiological activity.
- the present inventors have searched for a drug that can reduce endotoxin shock death, and as a result, have found that sialic acid and a polymer thereof can reduce endotoxin-induced shock death.
- the present invention has been completed in this manner.
- the first invention is directed to a remedy for endotoxemia and multi-organ insufficiency induced by the same comprising sialic acid or a salt thereof as an active ingredient. It is an abstract.
- the second invention also provides a therapeutic agent for endotoxinemia and a multi-organ dysfunction induced thereby, which comprises a polymer of sialic acid or a salt thereof as an active ingredient.
- dimer to trimer can be used as the polymer of sialic acid. Since up to 13-mers of sialic acid can be suitably produced, the upper limit is set to 13-mers.
- the dimer to dimer sialic acid polymer and its salt can also be expected to have the same pharmacological effect as sialic acid and its salt.
- sialic acid or a polymer salt thereof various pharmaceutically acceptable salts can be used, and as sialic acid monomer salts, sodium salt, potassium salt, calcium salt, magnesium salt
- a sodium salt is commonly used as the salt of the sialic acid polymer.
- the sialic acid referred to in the present specification refers to “N-acetylneuraminic acid”.
- the preparation of the present invention includes oral preparations such as tablets, capsules and powders, transdermal absorption preparations such as suppositories and vaginal preparations, and subcutaneous administration.
- Oral preparations for intraperitoneal administration and intravenous administration.
- Oral preparations are recommended for preventing disease, and injections are most preferable when urgency is required.
- Oral preparations, percutaneous absorption preparations, and injection preparations can be prepared by ordinary preparation methods. Examples of preparations of oral preparations and injections are as follows.
- Example of preparation of injection After dissolving 50 g of sialic acid or a polymer thereof in 100 ml of distilled water (Pipone Jin'-free), the pH is adjusted to 7 .
- Example of preparation of oral preparation A 280 mg of sialic acid or a polymer thereof sieved through 60 mesh is packed into a No. 3 gelatin capsule to prepare a capsule.
- the method of administration of the formulation of the present invention is better for patients with infectious diseases, especially when it is determined that they have been infected with Gram-negative bacteria, than when administration of endotoxinemia is confirmed. Higher effects can be obtained.
- the dosage varies depending on the patient's age, gender, degree of disease, etc., but cannot be specified in general.However, as sodium salt of sialic acid or its polymer contained in the injection, it is 1-2000 per adult per day. O mg / Kg, preferably 10 to 500 mg / Kg, may be administered, and the number of administrations per day is suitably 1 to 6 times. Intravenous infusion is also an effective means.
- Sialic acid is a substance that is contained abundantly in the terminal of sugar chains present on the surface layer of cells constituting the human body and in the terminal of sugar chains present in blood and body fluids. is there.
- the sialic acid and its polymer used in the present invention use a chemically synthesized product, a sialic acid aldolase-cytosine monophosphate-N-acetylneuraminic acid (CMP-NANA) synthase and a CMP-NANA transferase.
- CMP-NANA sialic acid aldolase-cytosine monophosphate-N-acetylneuraminic acid
- CMP-NANA transferase Any of an enzymatically synthesized product or a hydrolyzed product of coguchimic acid obtained by acidolysis of colominic acid may be used, but is not limited thereto.
- the therapeutic agent according to the present invention makes it possible to effectively treat endotoxemia and the multi-organ dysfunction induced thereby.
- FIG. 1 is a graph showing the effect of sialic acid on endotoxin shock in SMA-based horses.
- FIG. 2 is a graph showing a change in the specific glomerular filtration rate (the glomerular filtration rate at a predetermined time before the administration of physiological saline or sialic acid).
- FIG. 3 is a graph showing a change in specific renal plasma flow rate (renal plasma flow rate at a predetermined time point Z renal plasma flow rate before administration of saline or sialic acid).
- a saline solution of endotoxin (1 OmgZm 1) was intraperitoneally administered to mice at a rate of 0.1 ml Zmg (dose: 100 mgZK g). The number of surviving mice after 24 hours Observations The results are shown in Fig. 1. As shown in Fig. 1, 1 In the group without administration of sialic acid and its polymer, only 5 out of 16 (survival rate: 31.3) can survive 2 In the sialic acid 10 mg / Kg and 10 OmgZKg groups, 4 out of 8 animals (survival rate: 50%) and 7 animals (survival rate: 87: 5%) were observed, respectively.
- Sialic acid and its polymer were found to have an effect of reducing endotoxin shock, indicating that sialic acid and its polymer were We anticipated that some therapeutic effect would be observed in multiple organ dysfunction induced by the disease, and we used an experimental system of endotoxin-induced renal injury, a typical disease, to see the effect.
- the solution was administered intravenously (dose: 0.25 mg ZKg), blood and urine were collected for 90 minutes, and the concentrations of inulin and paraaminohippuric acid were measured, and renal clearance was calculated according to the following formula.
- the urine collection should be performed at intervals of 15 minutes after administration of sialic acid or physiological saline (Fig. 2 shows 15 to 0; 0 to 15; 15 to 30; Collect urine for 30 to 45 min; 45 to 60 min, measure urinary concentration for each fraction), and collect blood in the middle of urine collection time. Clearance value is shown at the midpoint of each fraction. I do.
