Alergia na pleśń
Etiologia i przyczyny

Alergia na pleśń jest wynikiem nadwrażliwości układu immunologicznego na zarodniki pleśni, które są wszechobecne w środowisku wewnętrznym i zewnętrznym. Mechanizm patofizjologiczny opiera się na produkcji specyficznych przeciwciał IgE po pierwszym kontakcie z alergenem, co prowadzi do degranulacji komórek tucznych i uwalniania histaminy przy kolejnej ekspozycji. Najczęściej uczulającymi gatunkami są Alternaria, Aspergillus, Cladosporium i Penicillium. Szczególną uwagę należy zwrócić na alergiczną aspergilozę oskrzelowo-płucną (ABPA), dotyczącą 1-2% pacjentów z astmą, wywołaną nadwrażliwością na Aspergillus. Ekspozycja na pleśnie jest czynnikiem ryzyka rozwoju i zaostrzenia chorób układu oddechowego, w tym astmy alergicznej, alergicznego nieżytu nosa oraz alergicznego zapalenia pęcherzyków płucnych. Zarodniki pleśni rozwijają się w warunkach wilgotności powyżej 60%, temperaturze 4,4–38°C oraz obecności celulozy, co sprzyja ich namnażaniu w wilgotnych pomieszczeniach, takich jak piwnice, łazienki czy kuchnie.

Etiologia, przyczyny i powstawanie alergii na pleśń

Alergia na pleśń jest reakcją nadwrażliwości układu immunologicznego na zarodniki pleśni obecne w środowisku. Pleśnie są rodzajem grzybów, które występują niemal wszędzie na świecie, zarówno w pomieszczeniach zamkniętych, jak i na zewnątrz. Alergia rozwija się, gdy układ odpornościowy osoby uczulonej uznaje zarodniki pleśni za obce i potencjalnie szkodliwe substancje, pomimo że dla większości ludzi są one nieszkodliwe12.

Mechanizm powstawania alergii na pleśń

Alergia na pleśń wynika z nadmiernej reakcji układu immunologicznego na kontakt z zarodnikami pleśni. Gdy osoba uczulona wdycha te zarodniki, jej organizm rozpoznaje je jako intruzów i wytwarza przeciwciała (immunoglobuliny E, IgE) w celu ich zwalczenia34. Podczas pierwszego kontaktu z zarodnikami pleśni, organizm wytwarza specyficzne przeciwciała IgE, które są ukierunkowane na określone rodzaje pleśni. Przy kolejnym kontakcie, komórki tuczne uwalniają histaminę i inne substancje chemiczne, które powodują objawy alergiczne3.

Reakcja alergiczna na pleśń może wystąpić natychmiast po ekspozycji lub może być opóźniona54. Wielokrotna ekspozycja na zarodniki pleśni z czasem może prowadzić do nasilenia objawów, ponieważ organizm wytwarza coraz silniejsze reakcje obronne1. Warto zaznaczyć, że reakcja na pleśń może być zarówno alergiczna, jak i niealergiczna, w postaci podrażnienia56.

Rodzaje pleśni powodujące alergie

Na świecie występuje ponad 1000 gatunków pleśni, jednak tylko kilkadziesiąt z nich wywołuje reakcje alergiczne27. Do najczęstszych alergenów pleśniowych należą589:

159

Szczególnie problematyczna może być alergia na Aspergillus, zwłaszcza u osób z przewlekłymi chorobami płuc. Istnieje rzadka jednostka chorobowa znana jako alergiczna aspergiloza oskrzelowo-płucna (ABPA), spowodowana nadwrażliwością na Aspergillus, która dotyka około 1-2% osób z astmą9.

Warto podkreślić, że uczulenie na jeden rodzaj pleśni nie oznacza uczulenia na wszystkie gatunki pleśni1710. Istnieją również pleśnie toksyczne, takie jak Stachybotrys chartarum (czarna pleśń), które mogą powodować poważniejsze problemy zdrowotne111.

Czynniki środowiskowe sprzyjające rozwojowi pleśni

Pleśnie rozwijają się w określonych warunkach środowiskowych, które sprzyjają ich namnażaniu. Do głównych czynników sprzyjających rozwojowi pleśni należą1213:

  • Wilgoć – pleśnie rozwijają się w wilgotnych środowiskach
  • Odpowiednia temperatura – zwykle między 4,4°C a 38°C (40-100°F)
  • Dostęp do tlenu
  • Źródło pokarmu zawierające celulozę (np. płyty gipsowo-kartonowe, papier)

312

Pleśnie można znaleźć zarówno wewnątrz, jak i na zewnątrz budynków. Typowymi miejscami występowania pleśni wewnątrz pomieszczeń są1415:

  • Wilgotne piwnice
  • Łazienki
  • Kuchnie
  • Miejsca z przeciekami lub zalaniami
  • Pomieszczenia o wysokiej wilgotności
  • Słabo wentylowane pomieszczenia

1615

Na zewnątrz pleśnie często występują w17:

  • Glebie
  • Kompostownikach
  • Stosach gnijących liści
  • Butwiejącym drewnie

117

Zarodniki pleśni mogą przemieszczać się w powietrzu, zwłaszcza gdy pleśń zostaje zaburzona przez dotyk lub prądy powietrza8. Warto zaznaczyć, że objawy alergii na pleśnie zewnętrzne są najbardziej powszechne od lipca do pierwszych silnych przymrozków, choć w cieplejszych klimatach mogą występować przez cały rok517.

Czynniki ryzyka rozwoju alergii na pleśń

Niektóre osoby są bardziej narażone na rozwój alergii na pleśń. Do głównych czynników ryzyka należą1815:

  • Predyspozycje genetyczne – historia rodzinna alergii lub astmy zwiększa ryzyko rozwoju alergii na pleśń
  • Mieszkanie lub praca w budynku z uszkodzeniami spowodowanymi przez wodę
  • Mieszkanie w domu o wysokiej wilgotności (powyżej 60%)
  • Słaba wentylacja
  • Przewlekła ekspozycja na pleśń
  • Istniejące schorzenia układu oddechowego, takie jak astma lub POChP
  • Osłabiony układ odpornościowy

191820

Krajowe Instytuty Zdrowia szacują, że około 3-10% populacji ma alergię na pleśń9. Jednakże wśród osób z astmą, szacunki dotyczące częstości występowania alergii na pleśń mogą sięgać nawet 80%21.

Pleśń jako alergen wewnątrzpochodny i zewnątrzpochodny

Alergia na pleśń może być wywołana zarówno przez pleśnie rosnące wewnątrz budynków, jak i te występujące na zewnątrz2. W przypadku pleśni wewnątrzpochodnych, zarodniki mogą być obecne w powietrzu przez cały rok, powodując chroniczne objawy alergiczne7. Z kolei pleśnie zewnątrzpochodne mają tendencję do sezonowego występowania, z nasileniem w ciepłych i wilgotnych porach roku22.

Zarodniki pleśni z zewnątrz mogą przedostawać się do wnętrza budynków przez otwarte okna, drzwi, systemy wentylacyjne lub przenoszone na ubraniach i butach23. Jeśli wewnątrz budynku jest nadmierna wilgoć, np. w wyniku przecieków dachu czy powodzi, zarodniki mogą osiedlać się i prowadzić do rozwoju pleśni23.

Rola mikotoksyn w alergii na pleśń

Niektóre rodzaje pleśni, określane jako toksygenne, wytwarzają substancje zwane mikotoksynami, które mogą być niebezpieczne dla zdrowia2322. Mikotoksyny mogą działać jako czynniki drażniące i mogą być związane z tzw. „syndromem chorego budynku”24.

Warto zauważyć, że kolor pleśni nie jest wskaźnikiem jej toksyczności22. Choć często mówi się o „czarnej pleśni” jako szczególnie niebezpiecznej, wszystkie rodzaje pleśni (i źródło ich produkcji) powinny być usuwane niezależnie od ich koloru22.

Badanie przeprowadzone przez Medical College of Wisconsin sugeruje, że niektóre osoby mogą doświadczać objawów spowodowanych raczej toksyczną niż alergiczną reakcją na ekspozycję na pleśń, choć przypadki takie są rzadkie25. Autorzy badania sugerują, że niealergiczne reakcje na ekspozycję na pleśń mogą być spowodowane innymi substancjami wytwarzanymi przez grzyby podczas metabolizowania pokarmu, ale potrzebne są dalsze badania, aby w pełni zrozumieć, jak i dlaczego te niealergiczne reakcje występują25.

Zespół nadwrażliwości na pleśń

„Zespół toksycznej pleśni” to kontrowersyjna diagnoza związana z ekspozycją na środowiska zanieczyszczone pleśnią24. Badania wskazują, że osoby narażone na pleśń mogą prezentować różne objawy, zarówno związane z IgE, jak i niezwiązane z IgE24.

Wiadomo, że pleśnie mogą wywoływać astmę i alergiczny nieżyt nosa poprzez mechanizmy zależne od IgE, powodować alergiczne zapalenie pęcherzyków płucnych poprzez inne mechanizmy immunologiczne oraz powodować zagrażające życiu pierwotne i wtórne zakażenia u pacjentów z obniżoną odpornością24.

Objawy przypisywane toksycznym skutkom działania pleśni, które nie są związane z IgE lub innymi mechanizmami immunologicznymi, wymagają dalszej oceny pod kątem patogenezy24. Jednakże badania wskazują, że reakcje alergiczne, a nie toksyczne, wydają się być główną przyczyną objawów w badanych grupach24.

Wpływ alergii na pleśń na układ oddechowy

Alergia na pleśń może mieć znaczący wpływ na układ oddechowy, szczególnie u osób z istniejącymi schorzeniami układu oddechowego9. Zarodniki pleśni, ze względu na swój mały rozmiar, mogą łatwiej przedostawać się do dolnych dróg oddechowych, gdzie mogą wywoływać napad astmy9.

Alergia na pleśń i astma

Alergia na pleśń jest istotnym czynnikiem ryzyka rozwoju chorób górnych i dolnych dróg oddechowych, takich jak astma21. Ekspozycja i uczulenie na alergeny grzybicze może promować rozwój i nasilenie chorób alergicznych, takich jak alergiczny nieżyt nosa i astma21.

U osób z astmą i alergią na pleśń, można mówić o astmie alergicznej5. Wdychanie zarodników pleśni może wywołać lub nasilić objawy astmy, takie jak świszczący oddech, duszność lub uczucie ucisku w klatce piersiowej312.

Warto zauważyć, że ekspozycja na pleśń jest znanym czynnikiem wywołującym astmę i może powodować stan zapalny i ucisk w układzie oddechowym oraz śluz w drogach oddechowych25. Jeśli masz astmę i alergię na pleśń, możesz zauważyć, że ekspozycja na zarodniki pleśni może wywoływać objawy astmy, takie jak duszność, ucisk w klatce piersiowej, świszczący oddech i kaszel25.

Alergiczna aspergiloza oskrzelowo-płucna

Rzadkim, ale poważnym powikłaniem alergii na pleśń, szczególnie na Aspergillus, jest alergiczna aspergiloza oskrzelowo-płucna (ABPA)522. Jest to schorzenie, w którym układ odpornościowy nadmiernie reaguje na grzyby Aspergillus, co prowadzi do przewlekłego kaszlu, duszności i stanu zapalnego płuc15.

ABPA może wystąpić u osób z astmą lub mukowiscydozą26. Dotyczy to około 1-2% osób z astmą9.

Alergiczne zapalenie pęcherzyków płucnych

Alergiczne zapalenie pęcherzyków płucnych (inaczej zwane nadwrażliwością pneumonitis) to rzadkie schorzenie, które może rozwinąć się w czasie u osób wrażliwych na pewne rodzaje zarodników pleśni w powietrzu2726.

Choroba ta występuje, gdy ekspozycja na cząstki unoszące się w powietrzu, takie jak zarodniki pleśni, powoduje stan zapalny płuc26. Objawy mogą obejmować gorączkę, dreszcze i suchy kaszel15.

Jednym z przykładów tego schorzenia jest „płuco farmera”, które jest często nierozpoznawane i może powodować trwałe uszkodzenia w postaci blizn na płucach2728.

Inne konsekwencje zdrowotne alergii na pleśń

Oprócz wpływu na układ oddechowy, alergia na pleśń może prowadzić do różnych innych problemów zdrowotnych29.

Wpływ na układ odpornościowy

Długotrwała ekspozycja na pleśń może prowadzić do przewlekłej aktywacji układu odpornościowego, co prowadzi do przewlekłego stanu zapalnego30. U osób z osłabionym układem odpornościowym, ekspozycja na czarną pleśń może również powodować zakażenia grzybicze (mikozę) w drogach oddechowych lub innych częściach ciała14.

Alergie skórne i reakcje kontaktowe

Ekspozycja na zarodniki pleśni może również prowadzić do reakcji skórnych u niektórych osób29. Może to obejmować pokrzywkę, obrzęk i świąd skóry7.

U osób uczulonych na pleśń, bezpośredni kontakt z pleśnią może również wywołać reakcję alergiczną31. Warto zauważyć, że ciągła ekspozycja na jakikolwiek rodzaj pleśni może potencjalnie mieć negatywne skutki uboczne wykraczające poza wysypki skórne związane z pleśnią, nawet dla osób, które nie są uczulone na pleśń32.

Alergie pokarmowe związane z pleśnią

Możliwe jest również uczulenie na grzyby w żywności, takie jak grzyby jadalne lub fermentowane produkty spożywcze1. Ten rodzaj alergii zwykle powoduje objawy miejscowe w jamie ustnej i może powodować wysypki lub nawet wpływać na oddychanie1.

Osoby z alergią na zarodniki pleśni często pytają, czy mogą mieć reakcję alergiczną, gdy spożywają żywność zanieczyszczoną pleśnią lub produkty takie jak grzyby, drożdże czy Quorn (białko grzybicze)6.

Podsumowanie etiologii alergii na pleśń

Alergia na pleśń jest złożonym schorzeniem, które wynika z nadmiernej reakcji układu immunologicznego na zarodniki pleśni422. Pleśnie są wszechobecne w środowisku, zarówno wewnątrz, jak i na zewnątrz budynków, i choć większość ludzi nie wykazuje reakcji na zarodniki pleśni, osoby uczulone mogą doświadczać różnych objawów, od łagodnych reakcji alergicznych po poważniejsze powikłania, takie jak astma czy alergiczne zapalenie pęcherzyków płucnych215.

Zrozumienie mechanizmów prowadzących do alergii na pleśń, rozpoznanie czynników ryzyka oraz identyfikacja specyficznych gatunków pleśni wywołujących reakcje alergiczne są kluczowe dla skutecznego zarządzania tym schorzeniem. Warto podkreślić, że choć obecnie nie ma sposobu na wyleczenie alergii na pleśń, istnieje wiele metod, które mogą pomóc w kontrolowaniu objawów i minimalizowaniu ekspozycji na zarodniki pleśni19.

    Molds are a type of fungus that exists almost everywhere in the world. The molds that grow inside our houses prefer dark and damp places and can be harmful to some people with immune systems that develop responses against mold. […] There are probably thousands of different types of molds. Its possible to be allergic to only certain types of mold. […] Some common ones include Alternaria, Aspergillus, Cladosporium and Penicillium. There are also toxic molds that can cause very serious illnesses. An example of a toxic mold is Stachybotrys, which is known as black mold. […] Molds produce spores. Allergies happen when your immune system is very sensitive to outside substances, such as mold spores. Your body produces antibodies against the mold spores. As youre repeatedly exposed to the mold spores over time, your body sees the mold spores as something to be destroyed and your immune system creates bigger reactions to protect you. […] Its also possible to allergic to fungi in food, like mushrooms or fermented foods. This type of allergy generally causes local symptoms in the mouth and can cause rashes or even affect breathing. […] Currently, theres no way to cure an allergy to mold.

    Molds live everywhere—on logs and on fallen leaves, and in moist places like bathrooms and kitchens. Some people are allergic to these molds. An allergy occurs when you react to things like mold or pollen (called allergens) that don’t affect most people. […] There are roughly 1,000 species of mold in the United States — many of which aren’t visible to the naked eye. As tiny mold spores become airborne, they can cause allergic reactions in people who have mold allergies. […] If you suspect you might have a mold allergy, or if you have similar symptoms that continue to persist, consult an allergist. Allergists are specially trained to help you take control of your allergies and asthma, so you can live the life you want. They can conduct skin or blood tests that help pinpoint the allergy. […] Exposure to mold allergies can occur just about anywhere — in the home, outdoors or at work.

    In order to grow and spread, it needs moisture, oxygen, a temperature between 40 and 100 degrees Fahrenheit (4.4 and 38 degrees Celsius), and a food source that contains cellulose, such as drywall or paper. […] Breathing in black mold spores causes an allergic reaction if you have black mold allergies. An allergic reaction is your body’s response to an allergen. […] If you have black mold allergies, your body responds to your first encounter with black mold spores by creating immunoglobulin E (IgE). […] Your body makes different types of IgE, which target specific kinds of allergens, including black mold. […] The next time the mast cells encounter black mold spores, the mast cells release histamine and other chemicals. Histamine is what causes your immediate allergy symptoms. […] Black mold exposure can also trigger or worsen asthma symptoms. […] There isn’t any evidence that black mold exposure causes other serious health issues such as memory loss, nosebleeds, body aches or mood disorders.

    If you have a mold allergy, your immune system overreacts when you breathe in mold spores. […] Like any allergy, mold allergy symptoms are triggered by an overly sensitive immune system response. When you inhale tiny, airborne mold spores, your body recognizes them as foreign invaders and develops allergy-causing antibodies to fight them. […] Various molds are common indoors and outdoors. Only certain kinds of mold cause allergies. Being allergic to one type of mold doesn’t mean you’ll be allergic to another. Some of the most common molds that cause allergies include alternaria, aspergillus, cladosporium and penicillium.

[…] Some of the most common molds that cause allergy symptoms are: Alternaria, Aspergillus, Cladosporium, Penicillium. […] Inhaling the spores causes allergic reactions in some people. […] Allergic symptoms from fungus spores are most common from July to the first hard frost. […] If you have asthma and are allergic to mold, you may have allergic asthma. […] Mold allergy can cause an allergic reaction right away. […] If your symptoms often get worse in a damp, humid, or moldy room like a basement, this may mean you have a mold allergy. […] Rarely, some people can have a more serious illness called allergic bronchopulmonary aspergillosis. […] Mold is an irritant as well as an allergen.
  • #6 Allergy to Mould | Anaphylaxis UK
    https://www.anaphylaxis.org.uk/fact-sheet/allergy-to-mould/
    For some people, the spores that moulds release into the air can cause allergic reactions. […] Not all symptoms triggered by dampness and mould are allergy related. There is strong evidence from studies that, for some people, symptoms triggered by dampness and mould can have non-allergic causes. […] The allergen isnt the mould itself; instead, it is the spores released by the mould when the temperature in a damp environment rapidly increases. […] People with allergy to mould spores often ask if they might have an allergic reaction when they eat food contaminated with mould, or foods such as mushrooms, yeast or Quorn (mycoprotein derived from fungus).
  • #7 Mold Allergy |
    https://asthmaandallergies.org/asthma-allergies/mold-allergy/
    Molds live everywhere. Disturbing a mold source can disperse mold spores into the air, triggering an allergic response in some people. […] Although there are many types of molds, only a few dozen are known to cause allergic reactions. Molds most likely to trigger an allergic response include the following: Alternaria, Aspergillus, Aureobasidium (Pullularia), Cladosporium (hormodendrum), Epicoccum, Fusarium, Helmin-thosporium, Mucor, Pencillium, Rhizopus. […] It is common for people to develop an allergy to one or more types of mold if they, or other family members, have a history of allergic responses to things such as pollen or animal dander. […] Some people may become allergic only to mold or they also may have problems with other allergens such as dust mites, pollen, or certain foods.

    Mold is a living, microbial organism that grows from certain fungi and reproduces as a part of its life cycle. […] All mold types and their parent fungi grow in moist or damp environments, both inside and outside, and mold spreads via its seeds, better known as spores. Mold spores are microscopic and light enough to float up into the air whenever the growth site is disturbed, making them easy to inhale. […] Not all people are allergic to mold spores, but those with a mold allergy have an immune system that will treat the spores like a threat once encountered. […] As mentioned, not all people have immune systems that react to mold spores, meaning they do not suffer from allergic reactions the same way mold allergy patients do. […] There are toxigenic molds that can be harmful to anyone exposed, whether the person has a mold allergy or not. […] One of the most infamous toxigenic molds is Stachybotrys chartarum, more commonly known as toxic black mold.
  • #12 Mold Allergy
    https://www.aaaai.org/conditions-treatments/allergies/mold-allergy
    Molds are tiny fungi whose spores float through the air. They like damp environments and need four things to grow: food, air, appropriate temperature and water. […] Everyone breathes in mold spores in the air, but some people have an allergic reaction or asthma symptoms if exposed to too much of this fungus. […] If you are allergic to mold, your immune system is overly-sensitive to specific mold spores and treats them as an allergen. […] There are hundreds of types of molds, but not all of them are responsible for causing allergy symptoms. The most common allergy-causing molds include Alternaria, Aspergillus, Cladosporium and Penicillium. […] Mold can also trigger asthma symptoms such as wheezing, shortness of breath or chest tightness. […] If you have a mold allergy, avoiding exposure to the allergen is the best way to manage your symptoms. […] Immunotherapy (allergy shots) are a form of treatment that provides long-term relief of symptoms.

    Mold allergies happen when tiny particles called mold spores enter your body, either through the air or by touching your skin. These spores come from mold and, if you have an allergy, your immune system mistakenly thinks they’re harmful. This reaction causes the typical allergy symptoms. […] Mold loves to grow in damp and warm places. Here are some common spots where you might find it: Damp Basements: Basements are often cool and humid, making them perfect for mold. Bathrooms: Steam and moisture from showers and sinks create an ideal environment for mold. Kitchens: Cooking can produce steam and moisture that mold finds attractive. Areas with Leaks or Flooding: Water damage from leaks or floods can lead to mold on walls, floors, and ceilings. Outdoor Spaces: Compost piles and moist soil are also common places where mold can spread.
