Vaccination against HPV (human papillomavirus) to prevent disease

Human papillomavirus infection is one of the most common in the world. The situation is aggravated by the fact that the problem is rarely openly discussed in society, and people come to the doctor already in the late stages of the disease. Another difficulty lies in the fact that a virus that has already entered the body cannot be cured. The only way to protect yourself from it is timely vaccination.

What is HPV?

Human papillomavirus (HPV) is a non-enveloped DNA virus of relatively small size and simple structure. HPV tolerates high temperatures, exposure to ultraviolet rays, ether, chloroform and chemicals. The activity of the virus is neutralized by X-rays.

HPV is not one specific virus, but a large group of pathogenic genetically heterogeneous infectious agents of various types. There are about 600 of them in nature, but most of these viruses spread only among animals and are absolutely safe for humans. Of the total number of HPVs, only about a hundred affect the epithelium and mucous membranes of humans. In the vast majority of cases, the virus is sexually transmitted. The likelihood of infection can be influenced by various factors related to a person's health and behavior.

Diseases associated with HPV have been known since ancient times. Documents that have come down to us mention warts on the hands and soles and papillomas on the genitals. However, the opportunity to influence the spread of the virus appeared only at the beginning of the 21st century, along with the creation of effective vaccines against HPV. Work on the development of vaccines intensified after the connection was established between virus infection and the development of malignant tumors, primarily cervical cancer.

All human papillomaviruses known to medicine are divided into types depending on whether they are capable of causing cancer. According to the classification proposed by the International Agency for Research on Cancer (IARC), there are 3 high-risk HPV groups:

  • group 1 - high carcinogenic risk,
  • group 2A - probably carcinogenic risk,
  • group 2B - possibly carcinogenic risk.

About 14 types of human papillomavirus are oncogenic, that is, they can cause cancer. Viruses of types 16 and 18 are responsible for 75% of cases of cervical cancer.

The infectious process during HPV infection proceeds without a typical inflammatory reaction, since it is the only virus studied that does not enter the blood of an infected person. HPV penetrates through the mucous membranes into the basal layer of the epidermis. It is the lower layer of the skin, made up of cells capable of dividing. The constant division process ensures fast skin renewal.

The incubation period for human papillomavirus infection is 3 months on average. Further, the disease proceeds in three forms:

  • latent (latent), when a person does not have any clinical symptoms, but he becomes a carrier of the virus and begins to infect his sexual partners;
  • subclinical with minimal symptoms depending on the serotype of the virus;
  • clinical (manifest) with profuse rashes in the genital area.

Important!Virus infection and disease are not the same thing. At a young age, when the immune system is working at full strength, it is able to independently remove the pathogen from the body. In many countries of the world, screening for HPV is done only after 30 years, since before that it was not informative.

Once inside a healthy cell, the virus begins to produce its own DNA in it. Cells morphologically change, grow, turning into condylomas, warts and other skin formations.

In an infected cell, the virus exists in two forms:

  • benign - outside the cell chromosome,
  • malignant - when the DNA of the virus is introduced into the genome of the cell.

Interesting facts about the human papillomavirus

  • In both developed and underdeveloped countries, HPV is the most common sexually transmitted infection.
  • The particles of the virus are so microscopic in size that even a condom does not help 100% from infection during intercourse.
  • About 75% of people become infected during a single intercourse without a condom.
  • Most of the infected are in the age group from 20 to 24 years old, the main risk group is young people 17-33 years old.
  • The risk of infection is directly related to the immunological status: when immunity is weakened, for example, during pregnancy, the likelihood of infection increases sharply.
  • HPV itself is not a deadly disease; the risk of death arises when neoplasms transform into malignant tumors.

Clinically, HPV manifests itself in different ways:

  • Common warts on the back of the hands, feet, between the toes, on the scalp.
  • Long filamentous warts on the arms (Butcher's warts).
  • A group of flat warts raised slightly above the skin in the genital area, along the edge of hair growth, on the skin of the forearms.
  • Hereditary Lewandowski-Lutz disease. It is manifested by a large number of small dark warts or pronounced pigmentation.
  • Genital warts on the vaginal mucosa and male genital organs.

HPV affects the skin epithelium and mucous membranes of the male and female genitals, upper respiratory tract, rectum and other organs. Warts, warts and papillomas reduce quality of life, worsen appearance and affect self-esteem.

Where to go in case of illness

Since the disease is often asymptomatic, it is most often discovered by chance when undergoing medical examination. Various neoplasms on the skin - papillomas on the neck, in the armpit, under the breast, on the genitals and other parts of the body - usually become a cause for concern and seeking medical attention.

If any type of papillomas, warts and other neoplasms appear on the skin, you should immediately consult a dermatologist or dermatovenerologist.

To determine the degree of risk of developing cancer, a cytological analysis of tissues is performed:

  • To determine the oncogenicity of neoplasms on the skin, one of the warts is removed and its cells are examined to assess the presence of changes in them. Oncology is evidenced by degenerating or already degenerating into cancer cells.
  • To assess the development of cervical cancer, a cytological examination of scrapings from the mucous membrane of the cervix and cervical canal is performed. The analysis is carried out according to a technique specially developed for the early diagnosis of precancerous diseases of the cervix - Papanicolaou staining (PAP test).
  • To confirm the presence of the virus in the body and determine its type, PCR analysis of smears from the cervical canal in women and from the urethra in men is prescribed. Molecular biological PCR is used in addition to cervical screening in women over 30 years of age. The analysis is also prescribed for questionable results of cytology.

In 10-15% of infected people, the test detects several variants of the virus at once.

Important!It is necessary to consult a doctor at the first noticed neoplasms on the skin or mucous membranes. Early diagnosis of cancer offers a great chance of full recovery.

In the presence of papillomas on the skin and genital warts on the mucous membranes of the genitals, it is necessary to undergo an oncology examination at least once every 2 years.

Drug therapy

There is no specific treatment for HPV today. Despite the ongoing research all over the world, a drug for the destruction of the human papillomavirus has not yet been created.

It has been proven that the risk of HPV infection is directly related to the immune status of a person: with reduced immunity, the virus behaves more aggressively and more often causes the transformation of warts and papilloma cells into malignant tumors. In this regard, there is an opinion that drugs from the group of immunomodulators can be used as a drug therapy for the disease.

However, the clinical efficacy of drugs to increase immunity has not been proven by any scientific research, and they are not used anywhere in the world, except in post-Soviet countries. Most experts believe that the assurances of manufacturers in the high efficiency and absolute safety of these funds are nothing more than a marketing ploy.

Immunity is a complex multicomponent system, and modern science does not have knowledge of which links of this system need to be stimulated to fight viruses.

In clinical practice, destructive methods of treatment are mainly used - the removal of warts and papillomas using electrocoagulation, laser, cryodestruction, radiosurgery, and chemicals. After some time after removal, neoplasms on the skin may reappear, since destructive methods are not able to fight the virus itself. With a recurrent course, repeated removal is indicated.

Specificity of treatment in women

The question of the effectiveness of treatment and prevention of HPV in women is of particular importance, since the virus is one of the main causes of the development of cervical cancer. It is the fourth most common cancer in women around the world.

HPV in women manifests itself in the form of pale pink papillary growths in the external genitalia, vestibule and walls of the vagina, cervix, urethra. Formations on the cervix are detected when examined by a gynecologist using mirrors.

All women over the age of 21 and who are sexually active are encouraged to be screened for HPV every year. If HPV is detected at screening, a PAP test is prescribed.

If both analyzes confirmed the presence of a virus in the body, a more detailed examination is prescribed, including an analysis to identify pathological changes in tissues.

If the result of both tests is negative, the next comprehensive examination can be performed after 3 years. The risk group includes women with a negative PAP test, but with a positive screening result for HPV: they are assigned a colposcopy (examination of the cervix) and a biopsy - taking a tissue sample for research. The next examination is scheduled no later than one year later.

Important!HPV is not an obstacle to pregnancy and childbirth: the risk of transmitting the virus to your baby is minimal. If a woman does not have HPV and has not been vaccinated against infection, then the vaccination should be postponed until the end of the lactation period.

Treatment for men

In men, HPV is often asymptomatic, but men are carriers of the virus and infect their sexual partners. If papillomas do appear, then they are usually localized on the foreskin and glans penis, on the scrotum, in the anus and in the urethra.

The complex of treatment includes the destruction of papillomas with the aim of physically damaging their cells.

Traditional methods

Traditional medicine offers many recipes for getting rid of papillomas, but it is necessary to understand that removing any neoplasms on the skin without consulting a specialist and cytological examination of cells can lead to extremely negative consequences. Aggressive effect on cancer cells accelerates their growth and leads to the rapid development of malignant neoplasms.

From folk recipes for removing papillomas deserve attention:

  • celandine juice helps to get rid of papillomas when applied to the formation itself and its root several times a day;
  • alcohol tincture of dandelion flowers - lubricate several times a day until it disappears completely;
  • a mixture of squeezed garlic gruel with any cream or butter is applied to papillomas in the form of a compress for 2-3 hours.

Important!Before using any traditional medicine, you should consult your doctor!

Removal of papillomas by surgical methods

Modern medicine offers various effective methods of surgical removal of papillomas:

  • laser therapy - the efficiency reaches 90%, but there is a risk of relapse, and the wounds heal for a long time;
  • cryotherapy is highly effective, but the procedure requires high precision so as not to affect healthy tissues;
  • removal by chemical preparations is now rarely used due to the low efficiency and the risk of mucosal damage.

It is worth removing papillomas when:

  • significant aesthetic discomfort,
  • high risk of injury,
  • the likelihood of degeneration into malignant neoplasms.

Papillomas should be removed only in a medical facility on the recommendation of a doctor.

What to do if the papilloma is damaged

Injury to the papilloma is dangerous with the risk of infection of the wound and the acceleration of the growth of new formations.

In case of accidental damage to the papilloma, it is necessary to treat the injury site with an aseptic agent and apply a bactericidal adhesive plaster to the wound. If possible, you should consult a specialist.

The best treatment is prevention

The main method of protection against HPV is timely vaccination. Vaccination in all developed countries is carried out for girls from 9-11 years old, and, for example, in the USA and Canada, boys are also vaccinated to reduce the number of carriers of the virus.

Important!The most effective vaccination is before the onset of sexual activity. Although the vaccine can be obtained at any time, it will only protect against types of HPV that a person has not yet encountered.

Two HPV vaccines have been registered and approved for use. The vaccine, which is produced in the United States, protects against HPV types 16 and 18, which cause cervical cancer, and against types 6 and 11, a common cause of warts, genital warts and other neoplasms. The vaccine produced in Belgium protects against the 16th and 18th types of the virus.

HPV vaccines have undergone many clinical trials and have proven to be highly effective and completely safe. They contain only viral envelope proteins that serve as antigens for immune cells. The risk of developing cervical cancer after vaccination is reduced by more than 90%.

Conclusion

HPV is a very common infection that in many cases can significantly reduce the quality of life. Despite the lack of drugs for the virus, timely vaccination and a serious attitude to methods of protecting against infection during sexual intercourse will help to avoid the disease.
