Description

Compositions for specific dissolution of urate crystals in joints
Technical Field
The invention relates to the technical field of gout treatment, in particular to a composition capable of specifically dissolving urate crystals in joints and reducing the clinical dosage of a gout treatment medicine.
Background
The gout attack process is as follows: the initiation is that the urinary acid salt crystals are precipitated in the joint to induce joint inflammation, the activity of inflammatory small NLRP3 in the joint and the expression, maturation and secretion of inflammatory factors IL-1 beta are rapidly increased, and a large amount of neutrophils are recruited to joint synovial fluid to amplify joint inflammation cascade. Meanwhile, urate crystals can induce oxidative stress under the mediation of NADPH and Myeloperoxidase (MPO), so that severe edema and pain nerve stimulation are caused, and severe pain and edema symptoms of joints of people are caused.
The patients progress from hyperuricemia to acute gout, chronic gouty arthritis and tophus, and the root cause is that urate crystals are crystallized and separated out in joints to induce joint inflammation. Whether gout and the pain level at the onset of gout are induced depends not only on the blood uric acid level, but also on the number and rate of urate crystals deposited at the joint: the more the deposition amount of the uric acid salt is, the faster the deposition speed is, the easier the gout is to be in attack, and the more serious the pain is when the gout is in attack; the smaller the deposition amount of the urate crystals, the slower the deposition speed, the less easy the gout is to be easy to attack, and the less intense the pain feeling is when the gout is to be attack. The crystallization of the urinary acid salt crystals in other tissues and organs can lead to injury of tissues and organs and induce complications.
Through follow-up of blood uric acid change of gout patients in conventional uric acid reduction treatment and sodium urate crystals deposited at joints (dual-energy CT quantitative determination of the volume and density of the sodium urate crystals deposited at joints), researchers such as Chui CSK and the like formulate a dissolution model of the gout patients, and find that: when blood uric acid is more than 430 mu moL/L, the dissolution time of sodium urate crystals deposited at joints is close to infinite length; the time for the sodium urate crystals deposited at the joints to begin to dissolve significantly at blood uric acid=240 μmol/L is 10-19 months, and still 4-8 months are required for the sodium urate crystals deposited at the joints to begin to dissolve when blood uric acid approaches 0. This indicates that: conventional uric acid lowering drugs have limited efficacy in alleviating and treating gout.
In addition, studies have shown that: the dissolution of urate crystals in joint bursa solution is mainly achieved by reducing sodium ions/increasing potassium ion concentration of bursa solution, increasing ABCG2 activity and expression (promoting uric acid transfer from bursa solution to blood) and the like. Therefore, according to the above-mentioned target thought, there is a need to develop a drug that specifically promotes dissolution of urate crystals in joints.

Mu.L of monosodium urate crystals (MSU) of 40mg/mL were injected into the footpads of the gout model group, the drug control group, and the composition experimental groups 1 to 17. After 2 days, the footpad thickness was measured, rats were sacrificed and the expression level of the inflammatory factor IL-1 beta was determined.
Statistics of the test results of the thickness of the foot pad and the expression level of the inflammatory factor IL-1 beta are shown in FIG. 7, and can be seen:
a) The test results for compositions 1-7 showed that: betaine, yam extract and chinaroot greenbrier extract and combinations thereof have certain effects of relieving gouty arthritis, but are poor in effect.
b) The test results for composition 8 showed that: the thickness of the rat model foot pad with acute gout shows a remarkable difference after the intervention of the composition 7 and the composition 8, which shows that the lily extract cooperates with the three to show remarkable effect of relieving acute gout, and the main molecular mechanism reduces the expression and secretion of inflammatory factor IL-1 beta.
c) The test results for composition 9 showed that: has obvious effect of relieving acute gout.
d) The test results for composition 10 showed that: composition 10 has a significant effect of alleviating acute gout and is superior to compositions 8 and 9.
EXAMPLE 6 clinical Effect of reducing blood uric acid
40 cases of chronic gouty arthritis patients (the disease history of gout is 3-15 years, the attack frequency is more than or equal to 8 times/year) are collected as subjects (the assigned city people hospitals), the subjects are randomly divided into 4 groups, each group comprises 10 persons, and the intervention modes are as follows: the blood uric acid levels were measured on day 15, 30, 45 before and after the intervention, with the statistics shown in the following table:
dry expected subject blood uric acid changes (mean ± standard deviation)
Group of Day 0 (front clothes) For 15 days For 30 days 45 days
Control group 734±47 733±33 717±45 729±38
Composition 8 726±28 609±42 456±52 394±29

Composition 10 724±34 596±33 414±19 359±24
The results show that: composition 8, composition 9 and composition 10 all significantly reduced uric acid, with composition 10 having the strongest uric acid reducing capacity, indicating that there is a potential interaction between the components of composition 8 and composition 9 to enhance uric acid reducing capacity, consistent with animal experimental data. In the above 3 composition intervention groups, the number of patients with blood uric acid below 420. Mu. Mol/L after 45 days of intervention was 9 (90%), 7 (70%), 10 (100%), respectively. Namely: the clinical test results show that the uric acid lowering effect of the composition 10 is optimal.
Meanwhile, the embodiment further collects the gout attack times, the joint pain eliminating time after attack and the joint swelling eliminating time in the dry expectation of the subject, and the statistical results are shown in the following table:
seizure frequency and pain sensation of the subject during intervention, and time to swelling elimination (mean ± standard deviation)
Group of Number of gout attacks Pain sensation eliminating time/h Swelling elimination time/h
ControlGroup of 2.3±0.7 63±13 117±15
Composition 8 0.8±0.4 9±3.6 26±7
Composition 9 0.1±0.1 2±1.3 9±2.8
Composition 10 0 0 0
The results show that: compared with the control group, the compositions 8, 9 and 10 had significantly improved prognosis, gout flares, joint pain elimination time and joint swelling elimination time. Of these, composition 10 works best, with no symptoms of redness, warmth, swelling of the joints and acute gout flares occurring in the patient during the intervention. It also shows that the components of the composition 8 and the composition 9 have potential mutual enhancement effect of relieving acute gout.
In addition, the present example further extended the clinical intervention time to 120 days for the subjects, and the double-energy CT was used to determine the volume of the joint urate crystals before and after the intervention for 120 days, and the dissolution effect of the urate crystals before and after the intervention was evaluated. Fig. 8 shows a three-dimensional reconstructed picture of dual-energy CT of intra-articular crystals before and after intervention in a portion of a subject.
The results of the changes in volume of urate crystals deposited before and after intervention are statistically shown in the following table:

Composition 10 3.96±0.42 2.65±0.37 -1.31±0.41
The results show that: dissolution of urate crystals deposited in the joints of 0 (0%) in the non-intervention group subjects, dissolution of urate crystals in the joints of 4 (40%) in the intervention group subjects, dissolution of urate crystals in the joints of 6 (60%) in the intervention group subjects, and dissolution of urate crystals in the joints of 9 (90%) in the intervention group subjects were performed in composition 10.
Example 8 composition 10 reduces the clinical dosage of uric acid lowering drugs and reduces the risk of side effects
There are 4 uric acid lowering drugs that have been marketed in China: allopurinol, febuxostat, benzbromarone, probenecid, which has severe renal toxicity, has been basically marketed today. The clinical application rate is ranked from high to low: febuxostat (about 69-70%) > benzbromarone (about 21-22%) > allopurinol (about 8-10%). Hyperuricemia and gout are chronic metabolic diseases, and need to be taken for a long time or even for a lifetime, and if the patients are treated by only uric acid lowering drugs, the patients can have side effects with different degrees, such as gastrointestinal tract loss, liver and kidney injury, increased death risk and the like.
In the embodiment, the mode that the febuxostat and the benzbromarone which are low-dose uric acid reducing medicines are singly used or respectively combined with the composition 10 is adopted to verify whether the composition 10 can reduce the dosage of the uric acid reducing medicines.
40 cases of chronic gouty arthritis patients (the disease history of gout is 3-15 years, the attack frequency is more than or equal to 8 times/year) are recruited as subjects (entrusted to the civilian hospitals of the Weifang), and the subjects are randomly divided into 4 groups of 10 persons each, wherein the subjects are respectively: 40mg febuxostat intervention group, 50mg benzbromarone intervention group, 20mg febuxostat+10 g composition 10 intervention group and 25mg benzbromarone+10 g composition 10 intervention group. The intervention period was 30 days and changes in blood uric acid during the intervention were observed.
The results are shown in the following table:
clinical effects of small doses of drug alone or in combination with composition 10
Figure BDA0004018576850000111
The results show that: after 15 days and 30 days of intervention, the clinical uric acid reducing effects of the 20mg febuxostat+10 g composition 10 intervention group and the 25mg benzbromarone+10 g composition 10 intervention group are respectively stronger than those of 40mg febuxostat and 50mg benzbromarone, namely the composition 10 can obviously reduce the clinical dosage of uric acid reducing medicines.
Moreover, during clinical intervention, the number of people who had developed symptoms of acute gout flares or joint redness, swelling, in the 40mg febuxostat intervention group, the 50mg benzbromarone intervention group, the 20mg febuxostat+10 g composition 10 intervention group and the 25mg benzbromarone+10 g composition 10 intervention group were 4 people (40%), 3 people (30%), 0 people (0%), respectively, i.e., composition 10 could reduce the risk of gout flares during drug uric acid lowering treatment.
