Definitions
- the invention relates to a method to reduce the incidence and prevalence of human papillomavirus (HPV), mainly types 16 and 18, and therefore to prevent the incidence of cervical cancer (CC); a method to modify the cervical microbiome thereby decreasing the inflammatory response; and a method of providing an increase in leukocytes which consequently causes an increase in local immunity in women infected with human papillomavirus and other sexually transmitted infections.
- HPV human papillomavirus
- CC cervical cancer
- CC cervical cancer
- a method to modify the cervical microbiome thereby decreasing the inflammatory response and a method of providing an increase in leukocytes which consequently causes an increase in local immunity in women infected with human papillomavirus and other sexually transmitted infections.
- IUD intrauterine device
- cervical cancer is the fourth leading cause of death in women in the world. It is proven and established that the human papilloma virus (HPV) is the leading cause of cervical cancer in women, particularly HPV types 16 and 18 are commonly known as the highest risk viruses.
- HPV human papilloma virus
- microbiota is a group of microorganisms that establish communication with human cells to maintain the homeostasis of the human body, for example, this microbiota can prevent the growth of pathogens.
- this balance is broken, and it may occur that some species that inhabit a specific niche are altered in a way that can lead to the development of cancer-like pathologies.
- Table 1 Cervicovaginal microiota found in women with four different diagnoses according to [Vicente Madrid Marina, 2018]
- the composition of the microbiota of a healthy woman is different from the composition of a woman diagnosed with cancer.
- the modification of the microbiota is related to the presence of intraepithelial lesion secondary to HPV.
- composition of the microbiota it can produce lactic acid and hydrogen peroxide which, according to this article, "have a protective effect against viral and bacterial infections".
- the article describes that two different mechanisms were recently proposed through how the microbiota contributes to cancer associated with a viral infection.
- the microbiota is directly affecting viral infectivity through "generation of byproducts that may be able to modulate bacteria-host interactions.”
- the second mechanism suggests that "bacteria-host interactions affect host gene expression and this modulation in turn affects viral production and may promote tumorigenesis associated with viral infection.”
- intrauterine devices which, in addition to containing copper in their design, also comprise an active agent. Depending on the type of compound used, these intrauterine devices will enhance contraception or help control bleeding or can even be used to treat some local infections such as chlamydia, gonorrhea and the like as described in international patent application W0200775086.
- the present invention relates to the specific use of the uterine cervical device granted in United States Patent No. 10,702,470 and published in US 2016/0296468 (2016), this device comprising only copper and having the necessary dimensions that allow it to be placed and fixed between the cervix and the woman's uterus.
- this uterine cervical device differs over the prior art, among other reasons, due to the increased amount of copper used, where the copper concentration is between 380 mm 2 and 524 mm 2 , preferably between 418 mm 2 and 524 mm 2 ; the presence of a copper filament in different forms, such as Solomon's Bar, Celtic Knot, Bracelet (H,I,J); a T-shaped frame formed of inert plastic material having between 15 and
- the present invention provides a method to reduce the incidence and prevalence of human papillomavirus, mainly types 16 and 18, thus preventing the development of cervical cancer in women.
- the invention also provides a method for modifying the cervical microbiota thereby decreasing both the local inflammatory response measured by cytokines, without being limited by any theory, it is considered that the cytokines involved may be, for example , CD4 and CCR5 cytokines, such as the progression of precancerous lesions in the cervix related to human papillomavirus including high-risk and low-risk viruses, mainly HPV types 16 and 18.
- the invention further provides a method for an increase in leukocytes which, consequently, causes an increase in local immunity. This increased immunity provides protection for other sexually transmitted infections in women such as chlamydial infection or gonococcal infection.
- the scheme that marks carcinogenesis associated with cellular DNA damage with progression to premalignant lesions, associated with the inflammatory response, infection by oncogenic viruses such as HPV 16 and 18, as well as the modification of the immune response is a highly synthesized scheme. of the mechanisms of action of infection in the development of cervical cancer.
- the inventors of the invention consider that the uterine cervical device used in the methods and its modalities claimed in the present invention modifies the biochemical environment, reducing the presence or viral load of HPV, with a decrease in the inflammatory response, an increase in the local immune response by modifying the microbiota and therefore, migration to a premalignant or malignant lesion.
- FIG. 1 a front view of a uterine cervical device used in the present invention comprising a plastic T-shaped frame with a horizontal arm (A), a vertical post (B) and at its lower end a sphere (F).
- a copper wire (C) is wound on each side of the horizontal arm;
- Two superimposed layers of copper filament (D) are also wound on the vertical arm in where the coils of these filaments are separated from each other (E).
- the figure also shows that there are placed ends of a length of copper winding inside the sphere (G); the length can be in different shapes such as Solomon's bar (H), Celtic knot (I) or bracelet (J).
- Therapeutic effect.- refers to a therapeutic and/or prophylactic benefit where the prophylactic benefit encompasses the delay or elimination of a disease or condition such as the incidence of human papillomavirus.
- Treatment.- refers to the treatment of a disease or condition in a human, particularly in women, and includes: prevention (when the disease or condition has not yet been suffered); inhibition and alleviation (once the woman is already infected with the disease or is suffering from a certain condition) which implies the arrest of the development of the disease and/or condition and the regression of the disease and/or condition that relieves the symptoms suffered, respectively.
- Leukocytes also called white blood cells, refer to those components present in the human body that defend it against all kinds of diseases. They are divided into granular and agranular leukocytes, where the first group comprises neutrophils, eosinophils, and basophils, and the second group comprises monocytes and lymphocytes.
- Cytokines.- are proteins or glycoproteins produced by different types of cells that act as regulators of immune and inflammatory responses.
- Cervicovaginal microbiota.- refers to a dynamic group of microorganisms that can modulate the local immune response in the cervix and can be classified into five groups according to [CURTY, Gislaine, et. to the.; "The
- CSTs community status types
- Lactobacillus crispatus, L. gasseri, L. iners, and L. jensen ⁇ are the dominant species of CSTs I, II, III, and V; while the CST IV shows an increase in anaerobic species such as Gardnerella, Megasphera, Atopobium and Prevotella.
- the invention provides a method to reduce the incidence and prevalence of human papillomavirus in women, mainly types 16 and 18, thus preventing the development of cervical cancer in women and comprises the following steps:
- a cervical uterine device comprising copper between about 380 m 2 to about 524 m 2 , preferably about 418 mm 2 to about 524 m 2 , distributed in a T-shaped frame having a horizontal arm having a length of between approximately 17.8 millimeters and approximately 32.2 millimeters, this T-shaped frame having a vertical post extending from the horizontal arm, the vertical post is between approximately 25.8 millimeters and approximately 36.2 millimeters long and approximately 1.7 millimeters in diameter, the horizontal arm having portions on opposite sides of the vertical post and a sphere attached to the vertical post; this T-shaped frame made of inert plastic such as polyethylene, propylene, polyester or silicone elastomer.
- the insertion step 2) is performed manually and without the use of any specific device for insertion. That is, devices such as speculum, tenaculum, uterine sound, ring forceps, scissors, usually used in the art are also used in this insertion step 2).
- the uterine cervical device used in the present method corresponds to the one claimed and granted in the Application for United States Patent NO. US 15/100900, United States Patent No. 10,702,470 comprising:
- a T-shaped frame formed of inert plastic material having between 15 and 23 weight percent radiopaque material, the radiopaque material being a combination of barium sulfate and titanium oxide, this T-shaped frame having a horizontal arm having a length between
- this T-shaped frame that has a vertical post that extends from the horizontal arm, the vertical post that is between
- the horizontal arm having portions on opposite sides of the vertical post; a sphere fixed to the vertical post, this sphere that is formed of inert plastic or copper, this sphere that has a diameter of 3.1 millimeters; a copper wire wound on each of the portions of the horizontal arm, this copper wire having a diameter between 0.25 and 0.26 millimeters and having a total copper area of between 35.8 and 36.2 square millimeters; a pair of copper strands wound on the vertical pole, each of the pair of copper strands having a diameter of 0.25 and 0.26 millimeters and a total copper area of 100 square millimeters, the pair of copper strands extending for a distance of between 20 and 25 millimeters; a length of a copper strand having an area between 146 and 250 square millimeters wound into the shape of a Solomon's bar or a Celtic knot or a bracelet, wherein the length of the
- the cervical uterine device used comprises 418 mm 2 of copper distributed in a T-shaped frame.
- the uterine cervical device can be kept in position for up to about 5 years and more preferably up to about 3 years.
- the method as claimed also comprises changing the uterine cervical device between about 3 to about 5 years after it is inserted.
- the method described above is also novel and inventive because it prevents the development of cervical cancer that shows a therapeutic effect because within the area of the sphere fixed to the vertical post the ends of a length of 99.9% pure copper winding with a length of about 150 to about 300 mm, and about 146 to about 250 mm 2 placed in the uterine cervical canal just adjacent to the folds or cavities of the cervix; that is, the structure of the uterine cervical device of the invention allows it to be placed inside the uterus and cervix of the woman where the lesions caused by the human papillomavirus, mainly types 16 and 18, can develop into cancer.
- the uterine cervical device used in the method of the present invention advantageously, has the necessary dimensions such that it comes into contact not only with the uterus but also with the cervix of the woman. population. Direct contact with the cervix is important, because, as previously mentioned, it is in this area where HPV lodges and can become cancer.
- Another embodiment of the invention is that the method described above allows the treatment of cervical cancer uterus developed in women by allowing the involution of premalignant and malignant lesions through the reduction of the local inflammatory response and the modification of the local microbiota.
- Another embodiment of the invention is a method that modifies the cervical microbiota of women, thereby reducing the cytokine-mediated inflammatory response and the progression of human papillomavirus-related precancerous lesions on the cervix, including high-risk viruses. risk and low risk; mainly HPV types 16 and 18.
- This method comprises inserting the previously described uterine cervical device into the female reproductive system, specifically the lower part of the uterine cavity and the endocervix. This device should be kept in place for up to approximately 5 years, preferably up to three years.
- a method of the invention further provides an increase in leukocytes which consequently causes an increase in local immunity.
- Increased local immunity provides protection for other sexually transmitted infections in women such as chlamydial infection or gonococcal infection.
- This method that allows an increase in leukocytes comprises inserting the previously described uterine cervical device into the female reproductive system, specifically in the lower part of the uterine cavity and the endocervix. This device should be kept in place for up to approximately 5 years, preferably up to three years.
- the uterine cervical device described in the invention will be tested mainly in patients already infected with the human papillomavirus, mainly types 16 and 18, by inserting this device in the lower part of the uterine cavity and endocervix, to demonstrate the reduction in the incidence and prevalence of human papillomavirus in women, mainly types 16 and 18, thus preventing the development of cervical cancer in women.
- this device will also be tested to show that by inserting it into patients already suffering from cervical cancer, they can be effectively treated so that involution of premalignant and malignant lesions can be expected, thus leading to improved the patient's life.
- this device will be tested in patients already infected with the human papillomavirus, mainly types 16 and 18, to determine and evaluate the viral load and the inflammatory load inside the uterus and cervix of women by measuring cytokines. , particularly cytokines CD4 and CC4, at three different times. The first measurement will be done before inserting the cervical device; the second will take place six months after the inserted the uterine cervical device; and the third will be done twelve months after the cervical device was inserted. Variations in these time intervals may occur as would be apparent to one skilled in the art.
- the device will be tested in patients already infected with human papillomaviruses, primarily types 16 and 18, by inserting the cervical device to show that the female microbiome changed after the device was inserted and placed inside her. uterus and cervix.
- the therapeutic effect of the device will be tested in women who do not have HPV infection or cervical cancer to demonstrate the preventive effect of the method.
