Definitions
- the present invention relates to the technical field of production processes of medicinal preparations containing peptides; more particularly, it belongs to the technical field of production processes of medicinal preparations containing leukocyte dialysable extract.
- Transfer factors which are produced by leukocytes and lymphocytes, are small water-soluble polypeptides of approximately 44 amino acids that stimulate or transfer cell-mediated immunity from one individual to another and across species, but it does not create an allergic response. Since transfer factors are smaller than antibodies, they do not transfer responses measured by antibodies, they are not immunogenic and therefore do not induce antibody production. The properties and characteristics of transfer factors have been discussed in patents US4816563, US5080895, US5840700, US5883224, and US6468534.
- Transfer factors have been described as therapeutic effective for treating Herpex simplex virus infection, for the treatment of acne, and for the treatment of Candida albicans infection. They have also been used to treat cryptosporidiosis in recipients treated with a specific transfer factor. On the other hand, it has also been used for the treatment of chickenpox as a pretreatment of children with transfer factor of individuals who had had chickenpox. For many years various methodologies have been used to obtain the transfer factor.
- patent application WO2007143957 describes a process for obtaining the factor from leukocytes; This process includes the following stages: adjustment of leukocyte homogenization, dialysis and / or ultrafiltration, concentration by lyophilization, adjustment of the medical crude solution, inter-operative tests, homogenization, prefiltration, ultrafiltration, sterilization by filtration, thermal inactivation, packaging of the product, and lyophilization.
- This process includes the following stages: adjustment of leukocyte homogenization, dialysis and / or ultrafiltration, concentration by lyophilization, adjustment of the medical crude solution, inter-operative tests, homogenization, prefiltration, ultrafiltration, sterilization by filtration, thermal inactivation, packaging of the product, and lyophilization.
- a very crude factor is obtained since it contains a large number of components that can mask the action of the factor.
- patent NLa2004000058 describes a method in which a leukocyte extract is subjected to sterilization by filtration, and chromatography by sephadex G-15. This process uses as a quality control the chemo test of peripheral blood or lymphocytes of thymus and rat spleen.
- a method by undergoing only a separation by sephadex does not guarantee that the purity of the factor since it contains a multitude of components that can interfere with the metabolic action of the factor.
- patent application US20030031686A1 describes a method for obtaining transfer factor from chicken eggs.
- This method consists in immunizing the birds with a certain antigen and from the eggs obtaining a water soluble fraction of the white; This fraction was subjected to three consecutive filtration processes: a) by filter paper, b) by vacuum using fiberglass filter, and c) filtration by a DURAPORE hydrophilic membrane to remove lipids and lipoproteins.
- the Fraction containing proteins is collected, frozen, and lyophilized.
- this process is extremely simple, it has the disadvantage of not having a separation of low molecular weight polypeptides, and therefore the product obtained contains proteins that interfere with the action of the transfer factor.
- US5840700 describes a method for obtaining substantially pure transfer factor having a specific activity of at least 5000 units per AU214.
- the process basically consists of contacting a sample that contains transfer factor to an immobilized antigen to which the factor specifically binds under conditions that favor the formation of the antigen-transfer factor complex.
- This complex is subsequently separated by reverse phase high performance liquid chromatography, and high resolution liquid chromatography by gel filtration.
- this process has the great disadvantage of requiring a large amount of antigen, resulting in a fairly expensive process.
- patent application ⁇ 0 ⁇ 43445 ⁇ 2 describes a method of obtaining transfer factor from colostrum of lactating cows. Said method basically consists of the following steps: centrifugation to obtain a cell precipitate, casein removal, ultrafiltration and dialysis, chromatography and lyophilization. This process has the great disadvantage of the poor availability of colostrum from cows or any lactating mammal.
- invention Specification
- the present invention reasonably improves the technical problem.
- obtaining the transfer factor from peripheral blood allows avoiding the difficult handling of the eggs of immunized hens established in patent applications US20020044942 and US20030031686A1.
- there is a larger source of the factor unlike cow colostrum established in patent application EP0143445A2.
- it has the advantage of obtaining a factor with greater degree of purity when using a purification step based on a liquid chromatography of ultraresolution by molecular exclusion;
- This primary stage overcomes the disadvantages present in those processes described in patent applications WO2007143957 and NLa2004000058.
- this process turns out to be low cost because no antigen is used for the purification of the factor, unlike what is described in US5840700.
- the present invention has a stage of biological validation of the factor, which allows discarding those batches of transfer factor that do not comply with said test.
- Figure 1 is a calibration curve of the transfer factor by ultra-resolution liquid chromatography by molecular exclusion. The different lines are different lots on which the test was carried out.
- Figure 2 is a standard molecular weight curve.
- Figure 3 is a calibration curve of the transfer factor.
- Figure 4 is a calibration curve of the transfer factor.
- Figure 5 is a graph corresponding to the effect of the transfer factor on the proliferation of the MG-63 cell line.
- Figure 6 is a graph corresponding to the effect of the transfer factor on the proliferation of the A20 cell line.
- the transfer factor is obtained from units of leukocyte concentrates.
- the units proceed to freeze and subsequently suffer five stages of freezing / thawing.
- the packages of leukocyte concentrates are grouped together to form batches of 20 leukocyte concentrates in plastic bags.
- the freezing cycles are started by storing the lots at -20 ° C for one week. Once the week is completed, the defrosting of the leukocyte concentrate packages is carried out by placing them on a board under running water. When completely thawed they are returned to -20 ° C and stored for a week. So on, until the five freeze / thaw cycles are met.
- the dialysis process begins by cutting a membrane for 12 KDa at a length of 1 meter with 40 cm. This membrane is placed inside a 4-liter beaker containing 2.5 liters of Elix water and boil for 10 minutes. Then, the dialysis membrane is removed and placed in another 4-liter beaker containing 2.5 liters of Elix water and boiled for 10 minutes. Subsequently, the dialysis membrane is removed and placed in another 4-liter beaker containing 2.5 liters of water. Elix and sterilize for 15 minutes at 121 ° C. The dialysis membrane is kept in sterile water until it is used.
- the dialysis membrane is prepared, said membrane is filled with the leukocyte extract subjected to the freeze / thaw processes.
- This process begins by cleaning the bags containing the leukocyte concentrate with 70% alcohol; subsequently, one of the ends of the bag is cut using sterile surgical scissors.
- the content of the leukocyte concentrate is emptied and measured by decantation within a test tube.
- the contents of the test tube are then emptied into a 1 liter glass bottle.
- the steps are repeated with the various bags until they have a volume of 1,100 liters of leukocyte concentrate inside the bottle. Subsequently, 800 milliliters of water is measured in a test tube, and this volume is passed into a sterile 2-liter bottle.
- one end of the dialysis membrane is removed and a knot is made 10 cm from the end, a second knot is made 7 cm from the end and the surgical thread is tied between the two knots.
- the other end of the dialysis membrane is removed and a finger is inserted into the membrane, with which the dialysis membrane is pushed into an accordion.
- the finger is removed and instead the neck of a funnel is placed, taking care not to break the membrane.
- the membrane is removed and the end that has the knots is placed inside a sterile 2-liter bottle, taking care to leave the surgical thread out of the bottle.
- the end of the surgical thread that is outside the bottle is held with surgical tweezers and the leukocyte concentrate concentrated into the funnel is decanted into the funnel until everything is poured into the dialysis membrane, taking care to put the membrane little by little into the 2 liter bottle.
- the funnel is removed from the end of the dialysis membrane and double knot leaving 3 cm away.
- a sterile clamp (clip) is placed between the two knots and a sterile aluminum cap is placed and left dialyzing for 20 hours. Once the 20 hours of dialysis have been completed, samples are taken for their corresponding analysis.
- the 10 KDa cartridge is sampled and will determine the amount of endotoxin present.
- System pressures are checked (10 psi at the feed port and 5 psi at the hold port).
- a hose is connected to the power port, install it in the peristaltic pump head and insert the other end into the bottle containing the 12 KDa dialyzed product.
- HOLD 1 Connect a third hose to the retention port and insert it into a third 20 L bottle labeled as HOLD 1 (note : Prepare a more labeled bottle as RETAINED 1, 1 because two bottles of retained product will be obtained). Turn on the pump peristaltic and program it at 1 L / min. Ultrafilter the entire product. Measure the total quantity of each product obtained with a 2 L test tube.
- the product of the three bottles with permeate product is homogenized (PERMEATED 1, PERMEADO 2 and PERMEADO 2,1) as follows: insert a hose into the container containing the PERMEADO product 2.1 install the hose in the head of a peri-pump and insert the other end into the bottle containing the PERMEADO 1 product, set the pump at 1 L / min and transfer half of the amount contained in the PERMEADO 2.1 container to that of PERMEADO 1.
- Example 4 Step of identification and quantification by ultra-resolution liquid chromatography by molecular exclusion
- This stage was carried out under conditions for qualitative and quantitative analysis by SEC-UPLC in the Acquity UPLC System Class H system using the Acquity BEH200 1.7 pm molecular exclusion column 4.6 x 150mm.
- the separation of the peptides was carried out with a 50 mM phosphate buffer solution with 50 mM sodium chloride at pH 7.0 and at a Socratic flow of 0.2 mL / min, with a total elution time of 15 min.
- the chromatographic conditions mentioned above were used to obtain a calibration curve for quantitative determinations.
- the chromatographic profiles of the transfer factor Lot 11 B01 were obtained, where 11 characteristic peaks can be observed, these results are shown in Figure 1.
- This chromatographic method allows us to make a qualitative analysis to detect the 11 characteristic peaks of transfer factor in a retention time interval of 8.5 to 13.5 min.
- the Biorad (1.35-670 kDa) and Tryptophan (62 Daltons) molecular weight markers were used, so we can infer that the factor peptides transfer have a molecular weight less than 17 kDa corresponding to the myoglobin of the Biorad standard.
