The three -child policy is here. I believe someone is always eager to try?Before preparing for pregnancy, when did you have to prepare in advance in addition to "money" and school district houses?
It is likely to be -HPV vaccine.
According to surveys, the more female pregnancy is, the greater the chance of infection with HPV and cervical cancer, and the HPV virus during pregnancy also has a great probability that maternal and infant transmission.But why are you pregnant and sexual life reduces the risk of infection with HPV?Today we will understand the relationship between HPV virus and pregnancy.
We are one of the few cervical cancer, mainly malignant tumors caused by virus infections.
At least 95%of cervical cancer is directly related to human papilloma infections (HPV).
Its pathogenic process is like this:
Infected HPV virus -leading to cervical epithelial tumors -tumor change was ignored -developed into cervical cancer.
At present, we have found nearly two hundred types of HPV subtypes. Some of the high -risk HPVs have higher carcinogenicity, and although other low -risk HPVs are not easy to cause malignant tumors, they may also cause genital "warts".We bring discomfort.
In the eyes of many people, most of the HPV infection is linked to sexual communication. Therefore, unmarried unmarried and unprofitable women with more sexual objects and sexual life are high incidence of HPV.But in fact, women who are preparing for childbirth, especially those who are preparing to have two babies and third babies, also need to prevent HPV virus infection.Because the risk of HPV infection during pregnancy is much higher than unmarried women, in the census data in some regions, the HPV infection rate of women in pregnancy is even more than doubled than unmarried women.
At present, the research reports of HPV infection rates during pregnancy are very different. Most reports are 24%to 30%, and women’s HPV infections during pregnancy are mainly high -risk HPV infections, accounting for 68.2%.The HPV infection rate of unmarried women is often between 10%-20%.
The probability of infection with HPV is high, and the probability of high -risk HPV infection is also high, allowing women to be pregnant, especially women who are pregnant, need to prevent and treat HPV.
The first is because of weak immunity during pregnancy -women during pregnancy are in high estrogen, accompanied by progesterone, velvet fur membrane promoter gonadotropins, human placenta prolactin and adrenaline secretion, which not only leads to active HPV replication, but alsoA variety of embryonic antigen produced by the fetal development during the development of the fetus jointly suppress the mother’s immune response and weaken the mother’s antiviral infection ability.
Second, the internal environment of pregnancy is prone to nourish bacterial virus -the changes in the growth of the cervix of the pregnancy women’s cervix, the movement of the migration, the activity of the basal cells, and the increase in vaginal secretions have provided a favorable environment for HPV growth.
Although about a quarter of pregnant women in my country are infected with HPV virus.However, because early infection with HPV virus does not have obvious discomfort, most people are still in a state of "ignorance and unknown".This also causes some people to have such a lucky idea: even if I infected the HPV virus, my body will not be uncomfortable now. Even if I may get cervical cancer in decades, there will always be a way to cure the medical technology at that time.Bar.
Here, Xiaobian also wants to say a vital point: HPV will affect children!
At present, although there is no strong evidence that whether the HPV virus will increase the risk of abortion and fetal malformations, there is already exact evidence that HPV’s harm to children
First, HPV infection increases the risk of premature premature birth and eclampsia.
The second is that HPV virus can spread vertically and cause fetal and infant infections.
In addition to the infection of the fetus through the blood, amniotic fluid, and placenta of the pregnant woman, the delivery will also cause the baby’s infection -existing data statistics, the baby who is infected with HPV infected during pregnancy, 58.24%of the oral pharmaceuticals have HPV fixed colonizationEssence
Adults have powerful and perfect immunity to deal with HPV.But as a weak immunity, it often needs to go through several months to completely erase the HPV virus.During this period, it is easy to cause lesions such as conjunctiva, oral pharyngeal, and reproductive tract, which leads to neonatal genitals and anal acuminatum, eye conjunctiva papilloma, and laryngeal papilloma.
Now that you know that the risk of HPV during pregnancy is much more troublesome, many people think of getting HPV vaccines.
So can you get vaccine during pregnancy and pregnancy?
At present, in the third phase of clinical trials of quasi -valence HPV vaccines during pregnancy, no adverse effects on pregnancy endings are not found, and the risk of abortion, dead tires, and fetal -related diseases will not be increased.Therefore, the tetravalent HPV vaccine has been included in the US FDA pregnancy period B drug (animal test shows that there is no evidence of fetal no damage, but there is no sufficient evidence of good comparison research on pregnancy women).
But for the sake of insurance, the current domestic guide is still: "HPV vaccination is not recommended during pregnancy." Therefore, Xiaobian also wants to remind women who prepare for pregnancy and children in the future.Her HPV vaccine.After all, vaccine is still our most efficient defense.
