Balanitis
Etiologia i przyczyny

Balanitis, czyli zapalenie żołędzi prącia, to stan zapalny obejmujący głównie żołądź, częściej występujący u mężczyzn nieobrzezanych, z częstością 3-11% w populacji. Etiologia jest wieloczynnikowa, z dominującą rolą infekcji grzybiczych, zwłaszcza Candida albicans, które proliferują w ciepłym, wilgotnym środowisku pod napletkiem, szczególnie u pacjentów z cukrzycą, gdzie glukozuria sprzyja rozwojowi drobnoustrojów. Zakażenia bakteryjne (Bacteroides, Streptococcus, Staphylococcus, Gardnerella vaginalis) oraz infekcje przenoszone drogą płciową (Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum, HSV, HPV, Trichomonas vaginalis, Mycoplasma genitalium, Haemophilus ducreyi) również odgrywają istotną rolę. Poza infekcjami, balanitis może być wywołane przez czynniki drażniące (mydła, detergenty, lateks, spermicydy), dermatozy (łuszczyca, egzema, liszaj płaski i twardzinowy, balanitis xerotica obliterans) oraz specyficzne formy zapalenia, takie jak balanitis Zoona czy balanitis circinata. Czynniki ryzyka obejmują niedostateczną higienę, stulejkę, cukrzycę (zwłaszcza u pacjentów stosujących inhibitory SGLT-2), otyłość, obniżoną odporność oraz brak obrzezania, który znacząco zwiększa ryzyko rozwoju balanitis poprzez sprzyjanie akumulacji smegmy i mikroorganizmów.

Przewlekłe zapalenie żołędzi wiąże się z 3,8-krotnym wzrostem ryzyka rozwoju raka prącia, w tym raka podstawnokomórkowego, płaskonabłonkowego, mięsaków Kaposiego oraz choroby Pageta pozasutkowej. Szczególnie u osób starszych z przewlekłym balanitis należy rozważyć obecność śródnabłonkowej neoplazji prącia (PeIN) oraz infekcji HPV wysokiego ryzyka. Diagnostyka powinna uwzględniać różnicowanie przyczyn infekcyjnych i nieinfekcyjnych, a leczenie dostosowane do etiologii, z uwzględnieniem kontroli cukrzycy i eliminacji czynników drażniących. Profilaktyka obejmuje edukację higieniczną, rozważenie obrzezania u pacjentów z nawracającymi epizodami oraz monitorowanie zmian skórnych pod kątem transformacji nowotworowej.

Etiologia zapalenia żołędzi prącia (Balanitis)

Balanitis, czyli zapalenie żołędzi prącia, to stan zapalny obejmujący główkę prącia (żołądź), który może również dotyczyć napletka (balanoposthitis) u nieobrzezanych mężczyzn. Zapalenie to dotyka około 3-11% mężczyzn w ciągu życia, występując częściej u osób nieobrzezanych.12 Etiologia tego schorzenia jest złożona i może wynikać z wielu różnych czynników, które zostaną omówione poniżej.

Przyczyny infekcyjne

Infekcje stanowią najczęstszą przyczynę zapalenia żołędzi prącia, przy czym zakażenia grzybicze, bakteryjne, wirusowe i pasożytnicze odgrywają istotną rolę w patogenezie tego schorzenia.12

Zakażenia grzybicze

Zakażenia grzybicze, szczególnie spowodowane przez Candida albicans, są najczęściej identyfikowaną przyczyną infekcyjną balanitis.12 Grzyby te naturalnie występują na skórze, ale mogą nadmiernie się namnażać w ciepłym i wilgotnym środowisku pod napletkiem nieobrzezanych mężczyzn.1 Kandydoza żołędzi (candida balanitis) jest szczególnie powszechna u mężczyzn z cukrzycą, gdzie podwyższony poziom glukozy w moczu sprzyja namnażaniu się grzybów.12

Zakażenia bakteryjne

Zakażenia bakteryjne stanowią drugą co do częstości przyczynę infekcyjnego zapalenia żołędzi.1 Do najczęściej izolowanych bakterii należą:12

1

Zakażenia przenoszone drogą płciową

Niektóre zakażenia przenoszone drogą płciową mogą być przyczyną zapalenia żołędzi prącia:12

12

Zakażenia pasożytnicze

Wśród zakażeń pasożytniczych mogących wywoływać balanitis wymienia się przede wszystkim świerzb (zakażenie małymi roztoczami drążącymi w skórze).12

Przyczyny nieinfekcyjne

Poza przyczynami infekcyjnymi, zapalenie żołędzi prącia może być wywoływane przez szereg czynników nieinfekcyjnych, które zostaną omówione poniżej.1

Nieodpowiednia higiena

Niedostateczna higiena u nieobrzezanych mężczyzn jest najczęstszą przyczyną balanitis.12 Nieodpowiednie mycie prącia i obszaru pod napletkiem prowadzi do gromadzenia się smegmy – substancji składającej się z łoju, złuszczonych komórek naskórka i bakterii.12 To tworzy idealne środowisko dla namnażania się drobnoustrojów, które mogą wywoływać stan zapalny.1

Warto jednak zauważyć, że również zbyt intensywne mycie może przyczynić się do rozwoju zapalenia żołędzi poprzez naruszenie naturalnej bariery ochronnej skóry.12

Czynniki drażniące i alergeny

Różne substancje chemiczne mogą działać drażniąco na delikatną skórę żołędzi prącia:12

  • Mydła, żele pod prysznic, detergenty i produkty perfumowane
  • Środki plemnikobójcze (spermicydy)
  • Lateks stosowany w prezerwatywach
  • Lubrykanty
  • Środki piorące i płyny do płukania tkanin
  • Wazelina i inne substancje stosowane miejscowo

12

Choroby skóry

Różne dermatozy mogą manifestować się jako zapalenie żołędzi prącia:12

  • Łuszczyca – może powodować małe, złuszczające się zmiany na żołędzi prącia1
  • Wyprysk (egzema) – może powodować znaczny stan zapalny żołędzi lub dowolnej części skóry narządów płciowych1
  • Liszaj płaski (lichen planus) – charakteryzujący się fioletowymi, dobrze odgraniczonymi płytkami1
  • Liszaj twardzinowy (lichen sclerosus) – objawiający się białymi plamami i zmianami strukturalnymi, pękaniem, pęcherzami krwotocznymi1
  • Balanitis xerotica obliterans (BXO) – specyficzna postać liszaja twardzinowego dotycząca żołędzi prącia, objawiająca się porcelanowo-białymi plamami lub grudkami o ostrych granicach1

1

Specyficzne typy balanitis

Istnieją również specyficzne typy zapalenia żołędzi o odmiennej etiologii:1

  • Balanitis Zoona (balanitis plasmacellularis) – dotyczy głównie starszych, nieobrzezanych mężczyzn, charakteryzuje się jasno określonym rumieniem żołędzi. Etiologia nie jest w pełni poznana, ale uważa się, że jest to reakcja na inne schorzenie podstawowe. Martwe komórki skóry, krople moczu, cząsteczki mydła i flora skórna zostają uwięzione przez napletek, który nie funkcjonuje prawidłowo, co prowadzi do podrażnienia i stanu zapalnego1
  • Balanitis circinata – związana z reaktywnym zapaleniem stawów, objawiająca się erozyjnymi blaszkami o lekko uniesionych brzegach na żołędzi1
  • Pseudoepitheliomatous keratotic and micaceous balanitis (PKMB) – rzadka postać

1

Choroby współistniejące zwiększające ryzyko

Cukrzyca

Cukrzyca jest najczęściej identyfikowanym schorzeniem podstawowym przyczyniającym się do rozwoju zapalenia żołędzi.12 Mężczyźni z cukrzycą typu 2 mają ponad dwukrotnie większe ryzyko wystąpienia balanitis przynajmniej raz w życiu.1 Mechanizm zwiększonego ryzyka obejmuje:1

  • Zwiększony poziom glukozy w moczu, który sprzyja rozwojowi bakterii i grzybów, szczególnie Candida1
  • Osłabienie funkcji układu immunologicznego1

1

Leki stosowane w leczeniu cukrzycy typu 2, takie jak inhibitory SGLT-2 (np. dapagliflozyna), które działają poprzez wydalanie cukru z organizmu w moczu, mogą dodatkowo zwiększać ryzyko zapalenia żołędzi poprzez zwiększenie stężenia glukozy w moczu.12

Stulejka (phimosis)

Zwężenie napletka (stulejka), czyli stan, w którym napletek nie może być cofnięty nad żołądź prącia, predysponuje do rozwoju zapalenia żołędzi.12 Stulejka utrudnia prawidłową higienę obszaru pod napletkiem, prowadząc do gromadzenia się smegmy i innych substancji drażniących.1

Inne choroby predysponujące

Inne stany chorobowe, które mogą zwiększać ryzyko rozwoju balanitis, obejmują:12

  • Reaktywne zapalenie stawów
  • Stany obrzękowe, takie jak prawokomorowa niewydolność serca, marskość wątroby i zespół nerczycowy
  • Otyłość patologiczna
  • Obniżona odporność (np. związana z zakażeniem HIV lub innymi przyczynami)

12

Czynniki ryzyka

Brak obrzezania

Brak obrzezania stanowi istotny czynnik ryzyka rozwoju balanitis.1 Dane z metaanaliz pokazują, że obrzezani mężczyźni mają znacznie niższą częstość występowania zapalenia żołędzi w porównaniu z nieobrzezanymi mężczyznami.1 Ciepłe, wilgotne środowisko pod napletkiem, brak wentylacji, gromadzenie się moczu i wydzieliny cewkowej oraz akumulacja drażniącej smegmy sprzyjają wzrostowi drobnoustrojów, najczęściej Candida, które powodują zapalenie żołędzi.1

Czynniki wiekowe

Zapalenie żołędzi występuje częściej w określonych grupach wiekowych:1

  • U chłopców poniżej 5 roku życia – ze względu na fizjologicznie wąski napletek oraz rozwijające się nawyki higieniczne12
  • U mężczyzn w średnim i starszym wieku – szczególnie tych z cukrzycą1

1

Stosowanie niektórych leków może zwiększać ryzyko zapalenia żołędzi:1

  • Antybiotyki – mogą zaburzać normalną florę bakteryjną, prowadząc do nadmiernego wzrostu grzybów1
  • Niektóre leki przeciwbólowe (np. tetracyklina, sulfonamid)
  • Leki przeczyszczające
  • Leki nasenne

12

Związek z rakiem prącia

Badania wykazały, że zapalenie żołędzi jest związane z 3,8-krotnym wzrostem ryzyka rozwoju raka prącia.1 Przewlekły stan zapalny może prowadzić do różnych powikłań zdrowotnych, w tym w rzadkich przypadkach zwiększa ryzyko rozwoju raka prącia.1 Istnieje również związek między niektórymi typami zapalenia żołędzi a stanami przedrakowymi lub nowotworowymi, takimi jak:1

  • Rak podstawnokomórkowy
  • Rak płaskonabłonkowy
  • Mięsak Kaposiego
  • Choroba Pageta pozasutkowa (EMPD)

1

W przypadku przewlekłego, nieustępującego zapalenia żołędzi, szczególnie u osób starszych, ważne jest rozważenie możliwości wystąpienia śródnabłonkowej neoplazji prącia (PeIN) lub raka prącia, zwłaszcza u osób z infekcją HPV wysokiego ryzyka.12

Podsumowanie etiologii balanitis

Zapalenie żołędzi prącia (balanitis) może być spowodowane wieloma różnymi czynnikami, z których najczęstsze to infekcje grzybicze (zwłaszcza Candida albicans), niedostateczna higiena u nieobrzezanych mężczyzn oraz współistniejąca cukrzyca. Inne przyczyny obejmują zakażenia bakteryjne, wirusowe i pasożytnicze, czynniki drażniące i alergeny, choroby skóry oraz stulejkę. Czynniki ryzyka obejmują brak obrzezania, wiek (dzieci poniżej 5 roku życia oraz mężczyźni w średnim i starszym wieku), cukrzycę oraz stosowanie niektórych leków. Przewlekłe zapalenie żołędzi może w rzadkich przypadkach zwiększać ryzyko rozwoju raka prącia.12

    Balanitis is inflammation of the glans penis. […] Balanitis and balanoposthitis are primarily infectious in origin, with Candida being the most common etiologic organism. […] Many diseases, infections, and disorders affect the male genitalia, including inflammatory lesions, infectious processes, preneoplastic syndromes, and malignant conditions. However, the most common cause of balanitis is poor or inadequate personal hygiene in uncircumcised males, leading to candidal infection. […] The warm, moist environment under the uncircumcised penile foreskin, lack of aeration, sequestration of urine and urethral discharge or seepage, and the accumulation of irritating smegma promote the growth of organisms, most commonly Candida, that cause balanitis, leading to erythema, irritation, edema, inflammation, and discomfort of the glans penis.

    Fungal infections, particularly those caused by Candida albicans, are the most common identifiable infectious causes of balanitis and balanoposthitis. […] Diabetes is the most commonly identified underlying contributing disorder. […] Data from meta-analyses show that circumcised males have a substantially lower prevalence of balanitis (68%) compared to uncircumcised males and that balanitis is associated with a 3.8-fold increase in the risk of penile cancer. […] Although yeast infection is the most commonly identified cause of balanitis, numerous other potential causes must be considered, including both infectious and noninfectious agents. […] Infectious etiologies of balanitis include: Anaerobic and aerobic bacteria such as Bacteroides, Streptococcus, and Staphylococcus; Candida species (most commonly associated with diabetes); Chlamydia species; Gardnerella vaginalis; Human herpesvirus 1 and 2; Human papillomaviruses; Neisseria gonorrhoeae; Scabies; Treponema pallidum, the etiologic agent of syphilis; Trichomonas species.

    Lichen sclerosis this is an inflammatory skin condition that affects the foreskin. […] It can cause the foreskin to become tight and difficult to retract over the head of the penis (phimosis) and cause balanitis. […] Diabetes people with diabetes are more susceptible to infections. An infection under the foreskin can cause balanitis. […] If diabetes isnt managed properly, glucose in your blood can overflow through your kidneys and into your urine. […] Glucose in your urine encourages bacteria to grow more than usual in the urine. This can increase your risk of having balanitis. […] Candidal balanitis is particularly common in men with diabetes.

  • #1 Balanitis: What Causes It and How To Treat It
    https://patient.info/mens-health/penis-problems/balanitis
    Balanitis is when the head of the penis (the glans) becomes inflamed. Balanitis is common and it can occur at any age. It more commonly affects boys aged under 5 years and also men who have not been circumcised. There is a form of balanitis that affects middle-aged or older men called Zoon’s balanitis. About one in 25 boys and about one in 30 uncircumcised men are affected with balanitis at some time in their lives. Not being circumcised increases the risk of balanitis. […] There are many different causes of balanitis. These include infectious and non-infectious causes. […] Poor hygiene around this area, combined with a tight foreskin, can lead to irritation by smegma. Smegma is a cheesy-like substance which forms under the foreskin if the end of the penis (the glans) under the foreskin is not cleaned. This is the most common cause of balanitis.
  • #1 Balanitis: what is it, causes, symptoms and treatments
    https://www.operarme.com/blog/balanitis-what-is-it-causes-symptoms-and-treatments/
    Balanitis is inflammation of the skin that covers the head of the penis, that is, the glans. This infection is most common in children or adults who have not been circumcised. […] Poor hygiene and phimosis are related to this disease, as they lead to the proliferation of fungi under the foreskin, causing balanitis. […] Balanitis is a male genital infection that is usually caused by fungi. This disease involves inflammation of the penis, more specifically of the glans. […] Balanitis is more common in uncircumcised men. […] This condition of the glans can develop in any man or child, and is more common in those who have not been circumcised. […] This disease is associated with factors such as diabetes, bacteria and germs or allergic reactions due to synthetic fibres in underwear or irritants such as bath gels, etc.

    https://www.urology-textbook.com/balanitis.html
    Balanitis xerotica obliterans (BXO) is the manifestation of lichen sclerosus on the glans penis. BXO presents with porcelain white spots or papules on the glans with a sharp border. The atrophy leads to phimosis, meatal stenosis, urethral stricture of the fossa navicularis, or, in females, to kraurosis vulvae. Lichen sclerosus is sporadically associated with squamous cell carcinoma.

    https://www.pcds.org.uk/clinical-guidance/balanitis
    Lichen sclerosus is one of a number of conditions that causes BXO. […] In persistent and recalcitrant (poor response to treatment) cases a biopsy is usually needed to look for lichen sclerosus, erythroplasia of Queyrat, and squamous cell carcinoma; a confident clinical diagnosis is not always possible or safe. […] If the 'balanitis’ does not improve with the treatments referred to above then it is important to consider lichen sclerosus, penile intraepithelial neoplasia, and occasionally squamous cell carcinoma. Manage accordingly.

    Most commonly, balanitis is due to an infection (fungal, bacterial, viral, parasitic). There are also some noninfectious types, which include: Zoons balanitis, circinate balanitis, pseudoepitheliomatous keratotic and micaceous balanitis (PKMB), fixed drug eruption, lichen planus. […] Theres also a link to some types of balanitis and precancerous or cancerous conditions, including: basal cell carcinoma, squamous cell carcinoma, Kaposi sarcoma, extramammary Pagets disease (EMPD). […] Untreated balanitis can cause chronic (long-term) inflammation. Lasting inflammation can lead to health issues, including: Balanitis xerotica obliterans (BXO), phimosis. […] Rarely, theres a link between chronic inflammation and a higher risk of developing penile cancer.

    https://www.skinhealthinfo.org.uk/condition/zoons-balanitis/
    Zoon balanitis describes inflammation of the head of the penis (glans penis) and foreskin. […] It is thought that Zoon balanitis is a reaction to another underlying condition. Dead skin cells, droplets of urine, soap particles and skin flora that are normally present on the skin are trapped by the foreskin that is not functioning normally. This leads to irritation and inflammation of the foreskin and the glans penis underneath it. Zoon balanitis is not caused by an infection, and cannot be passed on to a sexual partner. […] Zoon balanitis may be present on its own, or more often is a sign of an underlying skin condition such as lichen sclerosus or lichen planus. Lichen sclerosus can make the foreskin tight and more difficult to retract.

    https://www.urology-textbook.com/balanitis.html
    Balanitis in children usually arises from an infection of the smegma because of phimosis or adhesions of the prepuce. […] Balanitis caused by infection: Candida, bacteria, viruses (herpes). Oral therapy of diabetes mellitus with SGLT-2 inhibitors (e.g., dapagliflozin) leads to chronic glucosuria, which significantly increases the risk of external genital infections. […] Balanitis circinata presents with erosive plaques with slightly raised edges on the glans due to a Reiter syndrome. […] Balanitis in psoriasis: Manifestation of psoriasis (inversa) of the glans penis. […] Gangrenous balanitis: Fournier gangrene at the glans penis. Untreated disease can lead to organ destruction. […] Balanitis plasmacellularis (Zoon balanitis): Zoon balanitis presents with bright and sharply defined erythema of the glans. The inflammatory lesion of the glans of unknown etiology is relatively asymptomatic. Histology shows a plasmacellular infiltrate. A biopsy is necessary to rule out, e.g., erythroplasia of Queyrat.

[…] The exact cause of BXO is unknown, but an autoimmune disorder is thought to be the underlying mechanism. […] The exact cause of Zoon’s balanitis is not known. Postulations include either a bacterial infection or an autoimmune disorder. […] The micaceous risk factors are unknown, but an autoimmune or allergic reaction to an unknown substance is thought to be responsible. […] Balanoposthitis can have a variety of causes, including infections, skin conditions, allergies, and irritation from irritants such as soaps or condoms. […] If left not addressed, balanitis can lead to several complications, including: Scarring: difficulty retracting the foreskin, painful erections, and sexual difficulties.

    Balanitis may stem from several other medical conditions as well. These include allergic reactions, either to medications or skin contact irritants such as soaps, spermicides, or latex condoms. Some heart, liver, or kidney conditions can cause edema (swelling) in various parts of the body, including inflammation of the glans. It may also manifest from a skin condition such as psoriasis, eczema, or dermatitis (Wray, 2021). […] Men with type 2 diabetes mellitus are over twice as likely to have balanitis at least once in their lives (Unnikrishnan, 2018). The relationship is so strong that chronic or recurring balanitis may be an early sign of pre-diabetes. Patients with multiple bouts may wish to have their blood glucose levels checked (Wray, 2021).

    https://www.webmd.com/men/penis-disorder-balanitis
    Balanitis usually happens because of a bacterial, fungal, viral, or parasitic infection. […] Most cases of balanitis develop in people who have a foreskin and don’t keep it clean and dry. That’s because the types of organisms that cause balanitis, such as fungi, thrive in that moist and warm environment. Fungal infections cause most cases of balanitis. […] Other cause of balanitis include: Poorly managed diabetes and some type 2 diabetes medications, such as dapagliflozin (Farxiga). The drug works by flushing sugar out of your body in your urine. Sugar creates a breeding place for yeast to grow. […] Balanitis is most common in kids under age 4. As with adults, bad hygiene is the most frequent culprit. Kids have a higher risk if they’re still in diapers because coming into contact with poop and pee — such as while wearing a dirty diaper — can trigger balanitis.

It can cause symptoms such as irritation of the glans, redness, discomfort, swelling, small spots or discharge that is white and thick (or cheesy). […] There are many causes of balanitis, including dermatitis, irritants, fungal infection, bacterial infection, physical rubbing, yeast infection, poor hygiene, and also overzealous cleaning. […] Balanitis is much more likely to occur in men who are uncircumcised because the glans is covered by the foreskin, which creates a moist, closed, and warm environment for bacteria and fungi to overgrow. […] Another condition, balanoposthitis, means inflammation of the foreskin and glans, which has the same triggers and causes as balanitis. […] Common triggers and causes of balanitis include diabetes, particularly if your diabetes is poorly controlled, because the high amount of sugar in your blood allows fungi and bacteria to overgrow, plus your immune system is not able to function as well as usual.
