Brodawki narządów płciowych – Etiologia i przyczyny

Brodawki narządów płciowych
Etiologia i przyczyny

Kłykciny kończyste (condyloma acuminata) są wywoływane głównie przez niskoonkogenne typy HPV 6 i 11, które odpowiadają za około 90% przypadków. Wirus przenosi się przede wszystkim drogą kontaktu seksualnego (waginalny, analny, oralny), infekując keratynocyty i komórki nabłonkowe przez mikrouszkodzenia skóry i błon śluzowych. Okres inkubacji jest zmienny, a przebieg infekcji może obejmować eliminację wirusa przez układ odpornościowy (około 90% w ciągu 2 lat), stan latencji, rozwój widocznych brodawek lub, rzadko, zmiany przedrakowe przy zakażeniu typami wysokoonkogennymi (np. HPV 16, 18). Zakażenie jest przewlekłe, z możliwością nawrotów mimo leczenia, a osoby z obniżoną odpornością (HIV, immunosupresja) są szczególnie narażone na cięższy przebieg i ryzyko progresji nowotworowej.

Etiologia kłykcin kończystych (brodawek płciowych)

Kłykciny kończyste (brodawki płciowe, łac. condyloma acuminata) są jedną z najczęściej występujących chorób przenoszonych drogą płciową. Są one spowodowane zakażeniem specyficznymi typami wirusa brodawczaka ludzkiego (Human Papillomavirus, HPV)¹². HPV to grupa wirusów, których znanych jest obecnie ponad 150 różnych typów, a około 40 z nich może infekować obszar narządów płciowych³⁴.

Specyficzne typy HPV odpowiedzialne za kłykciny kończyste

Spośród licznych typów HPV, około 90% przypadków kłykcin kończystych jest spowodowanych przez tak zwane „niskoonkogenne” typy HPV 6 i 11⁵⁶. Te konkretne typy wirusa mają niski potencjał onkogenny, co oznacza, że rzadko prowadzą do rozwoju raka⁷. Chociaż HPV 6 i 11 są dominującymi typami powodującymi kłykciny kończyste, w niektórych przypadkach w brodawkach płciowych mogą być również wykrywane inne typy HPV, w tym HPV 16, 18, 31, 33 i 35⁸. Te wysokoonkogenne typy HPV są zwykle wykrywane jako koinfekcje z typami 6 lub 11, szczególnie u osób z obniżoną odpornością⁹.

Istotny jest fakt, że typy HPV powodujące kłykciny kończyste (głównie typ 6 i 11) różnią się od typów wysokoonkogennych (głównie typy 16 i 18), które są związane z rozwojem nowotworów, takich jak rak szyjki macicy¹⁰¹¹. Należy jednak zaznaczyć, że możliwa jest jednoczesna infekcja wieloma typami HPV, co oznacza, że osoby z kłykcinami kończystymi mogą być również zakażone typami wirusa związanymi z ryzykiem rozwoju raka¹².

Mechanizm transmisji

HPV jest wysoce zakaźnym patogenem, a zakażenie następuje przede wszystkim poprzez bezpośredni kontakt skóra do skóry¹³. W przypadku kłykcin kończystych główną drogą transmisji jest kontakt seksualny, w tym:

Stosunek waginalny¹⁴
Stosunek analny¹⁵
Seks oralny¹⁶
Bliski kontakt skóry okolic narządów płciowych¹⁷
Dzielenie się zabawkami erotycznymi¹⁸

Wirus HPV wnika do organizmu przez mikrouszkodzenia skóry lub błon śluzowych. Infekuje keratynocyty w skórze i komórki nabłonkowe błon śluzowych, stymulując je do proliferacji, co prowadzi do powstania widocznych zmian w postaci brodawek¹⁹²⁰. Wirus może przedostawać się przez drobne nacięcia, otarcia lub inne uszkodzenia skóry w okolicach genitalnych²¹.

Co istotne, HPV może być przenoszony nawet wtedy, gdy u zakażonej osoby nie występują widoczne brodawki²². Osoba zakażona może pozostać zakaźna nawet po leczeniu i usunięciu widocznych zmian, ponieważ sam wirus może nadal pozostawać w organizmie²³.

Okres inkubacji i przebieg infekcji

Okres inkubacji wirusa HPV jest bardzo zmienny – brodawki mogą pojawić się w ciągu kilku tygodni, miesięcy, a nawet lat po zakażeniu²⁴²⁵. Z tego powodu często trudno jest ustalić, kiedy i od kogo dana osoba zakaziła się wirusem.

Przebieg infekcji HPV charakteryzuje się kilkoma możliwymi scenariuszami:

U większości osób (około 90%) układ odpornościowy samodzielnie eliminuje wirusa w ciągu 2 lat od zakażenia²⁶²⁷
U niektórych osób wirus może pozostawać w stanie latencji (uśpienia) przez długi czas, bez wywoływania objawów²⁸
Wirus może także prowadzić do rozwoju widocznych kłykcin kończystych²⁹
W rzadkich przypadkach, szczególnie przy zakażeniu typami wysokoonkogennymi, może dojść do rozwoju zmian przedrakowych lub nowotworowych³⁰

Infekcja HPV jest chorobą przewlekłą i nawet po skutecznym leczeniu i usunięciu brodawek, wirus może pozostawać w organizmie, co może prowadzić do nawrotów choroby³¹³².

Czynniki ryzyka zakażenia HPV i rozwoju kłykcin kończystych

Chociaż każda osoba aktywna seksualnie może zakazić się HPV, istnieją określone czynniki, które zwiększają ryzyko zakażenia i rozwoju kłykcin kończystych³³:

Wielość partnerów seksualnych – zwiększa prawdopodobieństwo kontaktu z osobą zakażoną³⁴
Wczesne rozpoczęcie aktywności seksualnej – zwiększa łączną liczbę partnerów seksualnych w ciągu życia³⁵
Osłabiony układ odpornościowy – osoby z obniżoną odpornością (np. z powodu HIV/AIDS, cukrzycy lub stosowania leków immunosupresyjnych) mają większe trudności z eliminacją wirusa³⁶³⁷
Palenie tytoniu – badania wykazały, że osoby palące mają wyższe ryzyko rozwoju kłykcin kończystych³⁸³⁹
Ciąża – zmiany hormonalne w czasie ciąży mogą zwiększać podatność na rozwój kłykcin kończystych⁴⁰
Współistniejące zakażenia innymi chorobami przenoszonymi drogą płciową – zwiększają ryzyko zakażenia HPV⁴¹

Inne drogi zakażenia (poza kontaktem seksualnym)

Chociaż główną drogą transmisji HPV jest kontakt seksualny, istnieją również rzadsze drogi zakażenia:

Transmisja wertykalna (z matki na dziecko) podczas porodu – może prowadzić do rozwoju brodawczaków krtani u dziecka⁴²⁴³
Autoinokulacja – przeniesienie wirusa z brodawek na innych częściach ciała na okolice narządów płciowych⁴⁴
Kontakt z zanieczyszczonymi powierzchniami – istnieją doniesienia o możliwości zakażenia HPV poprzez kontakt z zanieczyszczonymi powierzchniami, takimi jak podłogi w przebieralniach, sauny czy wspólne prysznice, chociaż ta droga transmisji jest znacznie rzadsza⁴⁵⁴⁶

Związek między HPV, kłykcinami kończystymi a ryzykiem nowotworowym

Istotne jest rozróżnienie między typami HPV powodującymi kłykciny kończyste a typami związanymi z ryzykiem rozwoju nowotworów⁴⁷. Typy HPV 6 i 11, które są główną przyczyną kłykcin kończystych, są uważane za typy „niskoonkogenne” i rzadko prowadzą do rozwoju raka⁴⁸.

Natomiast wysokoonkogenne typy HPV (głównie HPV 16 i 18) są związane z rozwojem:

Raka szyjki macicy (odpowiadają za około 70% przypadków)⁴⁹
Raka sromu i pochwy⁵⁰
Raka prącia⁵¹
Raka odbytu⁵²
Raka jamy ustnej i gardła⁵³

Chociaż typy HPV powodujące kłykciny kończyste (typy 6 i 11) same w sobie nie zwiększają znacząco ryzyka rozwoju raka, osoby z kłykcinami kończystymi mogą być jednocześnie zakażone wysokoonkogennymi typami HPV⁵⁴. Ponadto, u osób z obniżoną odpornością, w szczególności u osób zakażonych HIV, ryzyko onkogenezy związanej z HPV jest wyższe⁵⁵.

Profilaktyka zakażeń HPV i kłykcin kończystych

Najskuteczniejszymi metodami zapobiegania zakażeniom HPV i rozwojowi kłykcin kończystych są⁵⁶:

Szczepienia przeciwko HPV – dostępne szczepionki chronią przed najczęstszymi typami HPV powodującymi kłykciny kończyste (HPV 6 i 11) oraz typami wysokoonkogennymi (HPV 16 i 18)⁵⁷⁵⁸. Szczepienia są najbardziej skuteczne, gdy są podawane przed rozpoczęciem aktywności seksualnej⁵⁹
Barierowe metody antykoncepcji – prezerwatywy mogą zmniejszyć, choć nie wyeliminować całkowicie, ryzyko transmisji HPV⁶⁰⁶¹
Ograniczenie liczby partnerów seksualnych⁶²
Regularne badania cytologiczne u kobiet – umożliwiają wczesne wykrycie zmian przedrakowych związanych z zakażeniem HPV⁶³

Epidemiologia i znaczenie kliniczne kłykcin kończystych

Zakażenie HPV jest jedną z najczęstszych chorób przenoszonych drogą płciową na świecie⁶⁴. Szacuje się, że około 80% aktywnych seksualnie osób zarazi się przynajmniej jednym typem HPV w ciągu swojego życia⁶⁵. Kłykciny kończyste, będące objawem zakażenia specyficznymi typami HPV, są również bardzo powszechne – każdego dnia około 1 na 100 aktywnych seksualnie dorosłych ma aktywne kłykciny kończyste⁶⁶.

Infekcja HPV i kłykciny kończyste mają istotne znaczenie kliniczne z kilku powodów:

Wpływ na jakość życia i funkcjonowanie psychoseksualne⁶⁷
Wysoka zakaźność – około 3 na 4 niezakażonych partnerów osób z kłykcinami kończystymi rozwinie brodawki w ciągu 8 miesięcy od kontaktu⁶⁸
Tendencja do nawrotów, nawet po skutecznym leczeniu⁶⁹
Związek z ryzykiem rozwoju nowotworów – szczególnie u osób zakażonych jednocześnie typami wysokoonkogennymi⁷⁰

HPV a immunosupresja

Osoby z obniżoną odpornością są szczególnie narażone na zakażenie HPV i rozwój kłykcin kończystych⁷¹⁷². Dotyczy to zwłaszcza:

Osób zakażonych HIV⁷³
Pacjentów przyjmujących leki immunosupresyjne (np. po przeszczepach narządów)⁷⁴
Osób z chorobami autoimmunologicznymi
Pacjentów onkologicznych poddawanych chemioterapii

U osób z obniżoną odpornością zakażenie HPV często przebiega ciężej, z większymi i bardziej licznymi brodawkami, częstszymi nawrotami oraz zwiększonym ryzykiem progresji do zmian nowotworowych⁷⁵.

Podsumowanie

Kłykciny kończyste są jedną z najczęstszych chorób przenoszonych drogą płciową, powodowaną przez zakażenie określonymi typami wirusa brodawczaka ludzkiego (HPV), głównie typami 6 i 11. Wirus ten przenosi się przede wszystkim poprzez kontakt seksualny, ale może być także przekazywany innymi drogami, takimi jak transmisja z matki na dziecko podczas porodu. Chociaż typy HPV powodujące kłykciny kończyste rzadko prowadzą do rozwoju raka, osoby z kłykcinami kończystymi mogą być jednocześnie zakażone typami wysokoonkogennymi, które zwiększają ryzyko rozwoju nowotworów.

Zapobieganie zakażeniom HPV i rozwojowi kłykcin kończystych obejmuje szczepienia przeciwko HPV, stosowanie barierowych metod antykoncepcji oraz ograniczenie liczby partnerów seksualnych. Ze względu na wysoką częstość występowania zakażeń HPV, tendencję do nawrotów oraz potencjalne powikłania, kłykciny kończyste stanowią istotny problem kliniczny wymagający właściwej diagnostyki i leczenia.

https://www.apderm.com/condition/genital-warts/?srsltid=AfmBOopkriDvN2FU1ZGehsruuoTUxFuXRpweFeECetWoiLPN5MsALbv_
Genital warts, known medically as condyloma acuminata, are mainly caused by infection with specific strains of the human papillomavirus (HPV). HPV types 6 and 11 are the primary causes, typically found in genital and anal areas where the virus can thrive. In this instance, HPV is transmitted through sexual contact, including vaginal, anal, and oral sex, and it enters the skin or mucous membranes through tiny cuts, abrasions, or skin openings.
