Vírus HPV

O que é HPV?

Sinônimos: vírus do papiloma humano
O HPV é um condiloma acuminado, conhecido também como verruga genital, crista de galo, figueira ou cavalo de crista, é uma doença sexualmente transmissível (DST) causada pelo Papilomavírus humano (HPV). Atualmente, existem mais de 100 tipos de HPV - alguns deles podendo causar câncer, principalmente no colo do útero e do ânus. Entretanto, a infecção pelo HPV é muito comum e nem sempre resulta em câncer. O exame de prevenção do câncer ginecológico, o Papanicolau, pode detectar alterações precoces no colo do útero e deve ser feito rotineiramente por todas as mulheres.Não se conhece o tempo em que o HPV pode permanecer sem sintomas e quais são os fatores responsáveis pelo desenvolvimento de lesões. Por esse motivo, é recomendável procurar serviços de saúde para consultas periodicamente.

Causas

A principal forma de transmissão do vírus do HPV é pela via sexual. Para ocorrer o contágio, a pessoa infectada não precisa apresentar sintomas. Mas, quando a verruga é visível, o risco de transmissão é muito maior. O uso da camisinha durante a relação sexual geralmente impede a transmissão do HPV, que também pode ser transmitido para o bebê durante o parto.

Sintomas de HPV

A infecção pelo HPV normalmente causa verrugas de tamanhos variáveis. No homem, é mais comum na cabeça do pênis (glande) e na região do ânus. Na mulher, os sintomas mais comuns do HPV surgem na vagina, vulva, região do ânus e colo do útero. As lesões do HPV também podem aparecer na boca e na garganta. Tanto o homem quanto a mulher podem estar infectados pelo vírus sem apresentar sintomas.

Tratamento de HPV

Na presença de qualquer sinal ou sintoma do HPV, é recomendado procurar um profissional de saúde, para o diagnóstico correto e indicação do tratamento adequado para o HPV.

Prevenção

Vacina

Foram desenvolvidas duas vacinas contra os tipos de HPV mais presentes no câncer de colo do útero: a vacina bivalente e a vacina quadrivalente. Essas vacinas, na verdade, previnem contra a infecção por HPV. Mas o real impacto da vacinação contra o câncer de colo de útero só poderá ser observado após décadas. Uma dessas vacinas é quadrivalente, ou seja, previne contra quatro tipos de HPV: o 16 e 18, presentes em 70% dos casos de câncer de colo do útero, e o 6 e 11, presentes em 90% dos casos de verrugas genitais. A outra é específica para os subtipos de HPV 16 e 18.
É fundamental deixar claro que a adoção da vacina contra o HPV não substituirá a realização regular do exame de citologia, Papanicolau (preventivo).
A vacina contra o HPV é mais uma estratégia possível para o enfrentamento do problema e um momento importante para avaliar se há existência de DST. Ainda há muitas perguntas sem respostas relativas à vacina do HPV:
  • A vacina do HPV só previne contra as lesões précancerosas ou também contra o desenvolvimento do câncer de colo de útero?
  • Qual o tempo de proteção conferido pela vacina do HPV?
  • Levando-se em conta que a maioria das infecções por HPV é facilmente debelada pelo sistema imunológico, como a vacinação afeta a imunidade natural contra o HPV?
  • Como a vacina afeta outros tipos de HPV associados ao câncer de colo de útero e condilomas (verrugas)?
A vacina do HPV funciona estimulando a produção de anticorpos específicos para cada tipo de HPV. A proteção contra a infecção vai depender da quantidade de anticorpos produzidos pelo indivíduo vacinado, a presença destes anticorpos no local da infecção e a sua persistência durante um longo período de tempo.
A duração da imunidade conferida pela vacina do HPV ainda não foi determinada, principalmente pelo pouco tempo em que é comercializada no mundo, desde 2007. Até o momento, só se tem convicção de cinco anos de proteção. Na verdade, embora se trate da mais importante novidade surgida na prevenção à infecção pelo HPV, ainda é preciso delimitar qual é o seu alcance sobre a incidência e a mortalidade do câncer de colo do útero.

  1. Meu nome é Sra Jesica Fredrich, de Domfront, paris. na França. No início do ano passado, i foi testado HIV positivo e desde então eu tenho sido gastar dinheiro em todo recebendo drogas de diferentes hospitais. Isso afetou minha carreira e meu trabalho, eu estava esperando a morte chegar e me levar, porque eu estava tão impotente. Um dia fiel, eu vi um blog na internet sobre como um determinado Dr.Gift curado uma senhora de herpes. I realizou um pouco de pesquisa e descobriu que ele tem ajudado as pessoas sem esperança de curar seu HIV e outras doenças. Então, entrei em contato com ele através deste e-mail: Drgifthivhealingcentre@gmail.com, preparou e enviou um poderoso ervas para mim, ele me disse como usá-lo. Para minha grande surpresa, depois que eu pacientemente atravessou o tratamento conforme indicado pelo Dr.Gift, eu fui para um exame médico e o resultado foi negativo. Eu pensei que era uma piada, então eu decidi ir para outro teste em um hospital diferente e novamente eles confirmaram me HIV negativo. Até o meu médico estava confuso, ele disse que nunca viu esse tipo de milagre antes. Eu realmente quero agradecer DR.Gift por salvar a minha vida, eu nunca acreditei que eu seja HIV negativo hoje, eu sou grato Sir. Se você está tendo HIV, diabetes, asma, HPV, herpes ou qualquer doença contacte-lo agora através de seu e-mail: drgifthivhealingcentre@gmail.com. ou chamá-lo 2349055637072.

  8. Estou aqui para testemunhar sobre o que o Dr. James fez por mim. Eu tenho sofrido da doença (VÍRUS GENITAL HERPES) nos últimos 4 anos e tinha dores e coceira constantes, especialmente na minha parte privada. Durante o primeiro ano, tive fé em Deus que um dia seria curado. Esta doença começou a circular por todo o meu corpo e estou a fazer tratamento com o meu médico e nada está a funcionar, há algumas semanas encontrei um testemunho do Pedro, na internet testemunhando sobre um fitoterapeuta chamado Dr. James da África Ocidental, sobre como ele o curou de 7 anos HSV 2. E ele também deu o endereço de e-mail desse homem [drjamesherbalmix@gmail.com], aconselhando qualquer pessoa a contatá-lo para obter ajuda em qualquer tipo de doença que ele ajudasse, então mandei um email pra ele contando do meu (HSV 2) ele falou pra eu não me preocupar que eu vou ficar curada !! Bem, eu nunca duvidei dele. Tenho fé que ele também pode me curar ,, O Dr. James preparou e me enviou Óleo Curativo, Sabonete, raízes e ervas que tomei. Na primeira semana, comecei a sentir mudanças em mim, após quatro semanas de uso do seu Roots / Herbs, Oil and Soap, estava totalmente curada. não há mais coceira e dor em mim, como o Dr. James me assegurou. Depois de algum tempo, fui ao médico fazer outro exame. o resultado saiu negativo. Portanto, amigos, meu conselho é se você tem essa doença ou conhece alguém que a sofre ou qualquer outra doença como HPV, HBV, HIV / AIDS, ALS, HBP, CÂNCER, SÍNDROME NEFRÓTICA, etc., você pode entrar em contato com o Dr. James herbal misturado em casa de bem-estar direto em seu [drjamesherbalmix@gamil.com] Ele é um bom homem e irá ajudá-lo.
