Zespół alfa-gal
Leczenie

Zespół alfa-gal (AGS) nie posiada obecnie skutecznej terapii przyczynowej, a podstawą leczenia jest eliminacja z diety produktów zawierających galaktozę-alfa-1,3-galaktozę, w tym mięsa ssaków (wołowina, wieprzowina, jagnięcina, dziczyzna, koźlina, królik), podrobów (nerki, wątroba) oraz pochodnych mięsa (żelatyna, kolagen). U około 5-20% pacjentów konieczne jest także wykluczenie produktów mlecznych. Leczenie objawowe obejmuje stosowanie leków przeciwhistaminowych (np. difenhydramina) w łagodnych reakcjach, doustnych kortykosteroidów w umiarkowanych oraz roztworu kromolinu na objawy żołądkowo-jelitowe. W przypadku anafilaksji niezbędne jest natychmiastowe podanie epinefryny i zapewnienie pilnej pomocy medycznej. Pacjenci powinni mieć przy sobie autoiniektor z epinefryną oraz być przeszkoleni w jego użyciu. Kluczowe jest także zapobieganie kolejnym ugryzieniom przez kleszcze, zwłaszcza kleszcza samotnika, poprzez stosowanie repelentów (DEET, pikarydyna, IR3535 w stężeniu min. 20%), odpowiednią odzież oraz szybkie usuwanie kleszczy.

Leczenie alfa-gal/” title=”zespół alfa-gal” class=”to-tag” data-termid=”34528″>zespołu alfa-gal

Obecnie nie istnieje skuteczna metoda leczenia zespołu alfa-gal (AGS). Podstawowe postępowanie terapeutyczne polega na unikaniu produktów zawierających galaktozę-alfa-1,3-galaktozę (alfa-gal) oraz na leczeniu objawowym reakcji alergicznych wynikających z przypadkowej ekspozycji123. Wczesne wykrycie schorzenia pomaga w opracowaniu indywidualnego planu postępowania dostosowanego do potrzeb pacjenta4.

Unikanie żywności zawierającej alfa-gal

Główną strategią terapeutyczną jest wykluczenie z diety potencjalnych alergenów, w szczególności56:

  • Mięsa ssaków: wołowina, wieprzowina, jagnięcina, dziczyzna, koźlina, królik
  • Podrobów ssaków: nerki, wątroba
  • Pochodnych mięsa: żelatyna, kolagen
  • W niektórych przypadkach (ok. 5-20% pacjentów) także produktów mlecznych, zwłaszcza gdy objawy nie ustępują po wykluczeniu samego mięsa

78

Unikanie produktów zawierających alfa-gal jest zadaniem złożonym, ponieważ znajdują się one w wielu artykułach spożywczych, lekach i innych produktach. Pacjenci powinni zawsze sprawdzać etykiety produktów spożywczych i konsultować się z lekarzem odnośnie leków i innych produktów, które mogą zawierać alfa-gal910.

Farmakoterapia reakcji alergicznych

W przypadku wystąpienia reakcji alergicznej stosuje się leczenie objawowe1112:

Pacjenci z rozpoznanym zespołem alfa-gal powinni posiadać przy sobie autoiniektor z epinefryną (np. EpiPen) oraz być przeszkoleni w zakresie jego użycia2122. Ważne jest opracowanie planu postępowania ratunkowego w przypadku przypadkowej ekspozycji na produkty zawierające alfa-gal23.

Zapobieganie ugryzieniom przez kleszcze

Istotnym elementem leczenia jest zapobieganie kolejnym ugryzieniom przez kleszcze, zwłaszcza przez kleszcza samotnika (Lone Star tick), ponieważ mogą one nasilać poziom przeciwciał IgE przeciwko alfa-gal, zwiększając wrażliwość na ten alergen2425.

Zalecenia obejmują2627:

  • Stosowanie środków odstraszających kleszcze zawierających DEET, pikarydynę lub IR3535 (min. 20% substancji czynnej)
  • Noszenie odzieży z długimi rękawami i nogawkami podczas przebywania w obszarach leśnych
  • Kontrolowanie skóry, włosów i ubrań po powrocie z terenów, gdzie mogą występować kleszcze
  • Szybkie i prawidłowe usuwanie kleszczy w przypadku ugryzienia

28

Rokowanie i potencjalne remisje

W przypadku niektórych pacjentów z zespołem alfa-gal objawy mogą z czasem łagodnieć lub nawet ustępować, szczególnie jeśli nie dochodzi do kolejnych ugryzień przez kleszcze przenoszące alfa-gal2930. Niektóre osoby mogą ponownie spożywać produkty pochodzące od ssaków po 1-2 latach bez kolejnych ugryzień przez kleszcze31.

Badania sugerują, że po wyeliminowaniu narażenia na kolejne ugryzienia kleszczy, poziom IgE przeciwko alfa-gal może z czasem obniżać się32. Okres remisji może trwać od 8 miesięcy do 5 lat, ale regularny monitoring poziomu przeciwciał i kontrola medyczna są niezbędne3334.

Czynniki nasilające reakcje

Niektóre czynniki mogą nasilać reakcje alergiczne u pacjentów z zespołem alfa-gal35:

3637

Świadomość tych czynników może pomóc pacjentom w lepszym zarządzaniu chorobą i unikaniu sytuacji zwiększających ryzyko ciężkiej reakcji alergicznej38.

Nowe podejścia terapeutyczne

Immunoterapia doustna

Desensytyzacja poprzez doustną immunoterapię (OIT) jest proponowana jako obiecująca metoda leczenia zespołu alfa-gal3940. Polega ona na codziennym spożywaniu bardzo małych i stopniowo zwiększanych ilości alergenu w celu zmniejszenia odpowiedzi immunologicznej i wywołania desensytyzacji41. Choć istnieją doniesienia o udanej desensytyzacji pacjentów z zespołem alfa-gal, metoda ta wymaga dalszych badań przed szerszym zastosowaniem klinicznym42.

Przeciwciała monoklonalne anty-IgE

Omalizumab, przeciwciało monoklonalne anty-IgE, jest badany jako potencjalna terapia dla pacjentów z zespołem alfa-gal43. Wstępne badania wskazują, że omalizumab może skutecznie kontrolować ciągłą reaktywność u pacjentów z AGS, umożliwiając wprowadzenie niewielkich ilości mięsa ssaków do diety4445.

Niektórzy badacze sugerują, że łączenie terapii anty-IgE z immunoterapią doustną może poprawić wyniki leczenia46. Jednak potrzebne są dalsze badania, aby określić długoterminową skuteczność i bezpieczeństwo tej metody47.

Nanocząsteczki w leczeniu zespołu alfa-gal

Obiecujące badania na myszach wykazały, że nanocząsteczki dostarczane dożylnie mogą blokować reakcje alergiczne na czerwone mięso wywołane przez ugryzienie kleszcza samotnika4849. Nanocząsteczki opracowane na Uniwersytecie Michigan zawierają alergeny, które „przekształcają” układ odpornościowy tak, aby ignorował typ cukru znajdującego się w wołowinie, wieprzowinie i innych produktach pochodzących od ssaków50.

Celem terapii z użyciem nanocząstek zawierających alergeny jest przeszkolenie układu odpornościowego, aby tolerował alergen po niewielkiej liczbie dawek, z ostatecznym celem osiągnięcia długotrwałej tolerancji51. Konieczne są jednak dalsze badania, aby lepiej zrozumieć implikacje i długotrwałe efekty leczenia nanocząsteczkami52.

Metody medycyny alternatywnej

Niektórzy pacjenci z zespołem alfa-gal poszukują alternatywnych metod leczenia. Jedną z takich metod jest akupunktura uszna, w szczególności Soliman Auricular Allergy Treatment (SAAT)53. W badaniu obejmującym pacjentów z AGS poddanych terapii SAAT, 96% uczestników zgłosiło remisję objawów po zabiegu54.

Metoda SAAT polega na umieszczeniu jednej cienkiej igły akupunkturowej w określonym punkcie małżowiny usznej55. Twórcy metody twierdzą, że zabieg jest bezpieczny, nie powoduje działań niepożądanych i może zapewnić długotrwałą ulgę od objawów alergii56. Zazwyczaj wymagane jest od jednego do trzech zabiegów57.

Choć istnieją doniesienia o skuteczności tej metody, niektórzy eksperci sugerują, że obserwowana poprawa może odzwierciedlać naturalny przebieg zespołu alfa-gal, ponieważ poziomy IgE mogą spontanicznie spadać u niektórych pacjentów58. Potrzebne są prospektywne badania z potwierdzeniem laboratoryjnym, aby ocenić skuteczność tej metody59.

Edukacja i wsparcie pacjenta

Edukacja pacjenta jest kluczowym elementem zarządzania zespołem alfa-gal60. Pacjenci powinni być poinformowani o61:

  • Źródłach alfa-gal w żywności, lekach i produktach codziennego użytku
  • Metodach zapobiegania ugryzieniom przez kleszcze
  • Objawach reakcji alergicznej i postępowaniu w przypadku jej wystąpienia
  • Konieczności noszenia identyfikatora medycznego i autoiniektora z epinefryną

Pacjenci z AGS powinni pozostawać pod opieką alergologa lub innego lekarza specjalisty62. Regularne badania poziomu przeciwciał IgE przeciwko alfa-gal mogą pomóc w monitorowaniu postępu choroby i potencjalnej remisji63.

Wsparcie dietetyczne może być pomocne w opracowaniu planu żywienia, który zapewni odpowiednią podaż składników odżywczych, mimo eliminacji mięsa ssaków i ewentualnie produktów mlecznych64. Szczególną uwagę należy zwrócić na zapewnienie odpowiedniej podaży wapnia, żelaza i witaminy B1265.

Leki i procedury medyczne u pacjentów z zespołem alfa-gal

Pacjenci z zespołem alfa-gal powinni być świadomi, że niektóre leki i produkty medyczne mogą zawierać alfa-gal66. Kapsułki żelatynowe, niektóre szczepionki, leki biologiczne i wyroby medyczne mogą zawierać składniki pochodzące od ssaków67.

Szczególną ostrożność należy zachować podczas procedur medycznych, zwłaszcza operacji, ze względu na dużą liczbę produktów stosowanych w krótkim czasie w tym środowisku68. Pacjenci powinni informować personel medyczny o diagnozie zespołu alfa-gal przed każdą procedurą medyczną i przed przyjęciem nowego leku69.

W przypadku heparyny, która jest pozyskiwana z trzewi świń lub bydła, dane sugerują, że nie wszyscy pacjenci z AGS wykazują reakcję na ten lek70. Decyzja o zastosowaniu heparyny powinna być podejmowana indywidualnie, w oparciu o poziom IgE przeciwko alfa-gal i konsultację z alergologiem71.

Podsumowanie aktualnego stanu wiedzy

Zespół alfa-gal stanowi wyzwanie diagnostyczne i terapeutyczne ze względu na nietypową prezentację kliniczną i opóźnione reakcje72. Ograniczona świadomość i wiedza na temat AGS wśród pracowników ochrony zdrowia prawdopodobnie przyczynia się do niedodiagnozowania tego schorzenia i nieadekwatnego postępowania z pacjentem73.

Obecnie nie ma zatwierdzonego przez FDA leczenia zespołu alfa-gal74. Podstawą postępowania jest unikanie produktów zawierających alfa-gal, zapobieganie ugryzieniom przez kleszcze oraz leczenie objawowe reakcji alergicznych75.

Trwają badania nad nowymi metodami leczenia, takimi jak immunoterapia doustna, przeciwciała monoklonalne anty-IgE i nanocząsteczki7677. Te obiecujące podejścia mogą w przyszłości zapewnić bardziej ukierunkowane i skuteczne leczenie pacjentów z zespołem alfa-gal78.

Do czasu opracowania skutecznego leczenia, edukacja pacjentów, ścisła współpraca z zespołem medycznym oraz przestrzeganie zasad profilaktyki ugryzień przez kleszcze pozostają kluczowymi elementami zarządzania zespołem alfa-gal79.

    https://pmc.ncbi.nlm.nih.gov/articles/PMC6980324/
    The -Gal syndrome has many novel features that are relevant to diagnosis and management. In general, the diagnosis also dictates the primary treatment, i.e. avoiding mammalian meat and also dairy in some cases. […] Blood levels of IgE to -Gal often drop in patients who avoid recurrent tick bites, but the rate of decline is variable. Similarly, the delay before reactions is variable and the severity of the allergic reactions is not predicted by the delay or the titer of specific IgE. […] The primary advice for newly diagnosed cases of the syndrome is to completely avoid meat of mammals. […] Avoiding products such as milk, yogurt, and ice cream is relatively easy because there are alternatives made from almond, oat, cashew or other non-mammalian sources. […] The argument about a dairy-free diet changes completely if consumption of -Gal containing products can contribute to inflammation without giving rise to allergic symptoms.

    Avoidance of meat, dairy products, and other products that contain alpha-gal. Individuals diagnosed with AGS should completely avoid the consumption of mammalian meat, including beef, pork, lamb, venison, goat, and rabbit. […] Because around 5% to 20% of people with AGS have allergic reactions to dairy products (which contain alpha-gal, though at lower levels than meat), health care providers may also recommend that some individuals with AGS avoid consuming dairy products, in particular those whose symptoms are not adequately controlled through meat avoidance alone. […] Many other products and medications may also contain alpha-gal. People with AGS should consult with their health care provider about which foods or other products they should avoid. […] Your doctor will discuss your history of reactions and monitor blood tests to help determine whether alpha-gal-containing foods can be eaten again.

    How is an alpha-gal allergy treated? Immediate symptoms such as hives or shortness of breath are treated the same as any other food allergy – in an urgent care setting with epinephrine, anti-histamines and other medications. Prevention long-term involves avoidance of all red meat in sensitized individuals. You may be advised to carry epinephrine, to be used in case of subsequent accidental exposures and reaction. These measures do not necessarily mean switching to a full vegetarian diet, since poultry and fish can be consumed and do not cause similar reactions. As with other food allergies, there is the possibility that over time the sensitivity diminishes although these changes may take many years to become apparent.

If you suffer from AGS and enjoy pork, you may safely consume pork that is developed under the GalSafe trademark. […] Since allergic reactions usually trigger the release of histamine locally or generally in the body, an antihistamine is the most effective alpha-gal allergy treatment. Antihistamine medication is readily available over the counter, such as Benadryl (diphenhydramine). An intense reaction like anaphylaxis must be treated with epinephrine. Your allergist will most likely prescribe an EpiPen for this purpose. […] A small study in 2020 suggested that Omalizumab may help AGS symptoms. According to the findings, 86% of patients in the study reported an improvement in symptoms after being exposed to mammalian food products by accident or on purpose. You may discuss the use of Omalizumab with your doctor if you have AGS. […] AGS is an acquired allergy from a tick bite that causes adverse bodily reactions when eating red meat. A delayed response occurs after three to six hours of eating mammalian products.

    The primary strategy for managing AGS involves strict avoidance of red meat and products derived from mammals. Although very rare, some people with severe AGS may react to ingredients in certain vaccines or medications. This dietary adjustment is crucial to preventing allergic reactions and minimizing the impact of AGS on an individual’s quality of life. On the bright side, enjoying other kinds of meats like poultry, fish, and shellfish won’t lead to symptoms of Alpha-Gal Syndrome. Eggs, fruits, and vegetables are also safe to eat! […] Preventing tick bites is paramount in reducing the risk of AGS. Individuals in regions with lone star tick prevalence should adopt measures such as using insect repellent, wearing protective clothing, and conducting thorough tick checks after outdoor activities. Steer clear of grassy, brushy, and wooded areas where ticks may lurk, and stick to the center of trails while walking. For the best defense against tick bites, go for repellents with at least 20% of active stuff like DEET, picaridin, or IR3535. However, it’s worth noting that using DEET products with concentrations exceeding 50% won’t necessarily provide added defense against tick bites. Stick to the recommended range for optimal results.

Make sure they don’t have red meat or meat-based ingredients, such as: […] Be extra careful when you eat at restaurants and social get-togethers. Many people don’t understand how serious an allergic food reaction can be. And few people know that meat allergies exist. Even a small amount of red meat can cause a serious reaction. […] For a serious allergic reaction, you may need a shot of epinephrine and emergency care. Many people with allergies carry a device called an epinephrine auto-injector. It’s a syringe and concealed needle that injects a single dose of medication when you press it against your thigh. If you’ve been diagnosed with alpha-gal syndrome, your doctor or allergist likely will prescribe an epinephrine auto-injector. […] Symptoms of alpha-gal syndrome may lessen or even disappear over time. This is especially true if you don’t get any more bites from ticks that carry alpha-gal. Some people with this condition can eat mammal food products again after 1 to 2 years if they don’t get any more tick bites.

    In addition to avoiding triggers, such as mammalian meat, treatment is aimed at alleviating symptoms and is highly dependent on severity. If an allergic individual who only experiences relatively mild symptoms consumes food containing alpha-gal, then treatment with over-the-counter antihistamines may be acceptable. In cases where more severe reactions like anaphylaxis are observed, admission to a hospital for emergency treatment is necessary. In these situations, treatment is the same as for any anaphylactic reaction, and necessitates epinephrine administration.

[…] There is no cure for alpha-gal; the main form of management is abstaining from mammalian meat, including lamb, beef, pork, and other mammalian products if necessary. These products have been found to have the highest risk of reaction, whereas dairy products present a much lower risk. Avoidance of dairy is not generally recommended as most afflicted individuals do not have reactions to dairy consumption. Unlike most food allergies, in some people, the alpha-gal allergy may recede over time as long as another tick does not bite the person. It has been found that with avoidance of further tick bites, levels of serum IgE decline. The recovery period can take 8 months to 5 years.

    The -Gal syndrome has many novel features that are relevant to diagnosis and management. In general, the diagnosis also dictates the primary treatment, i.e. avoiding mammalian meat and also dairy in some cases. […] Blood levels of IgE to -Gal often drop in patients who avoid recurrent tick bites, but the rate of decline is variable. Similarly, the delay before reactions is variable and the severity of the allergic reactions is not predicted by the delay or the titer of specific IgE. […] The primary advice for newly diagnosed cases of the syndrome is to completely avoid meat of mammals. […] Avoiding products such as milk, yogurt, and ice cream is relatively easy because there are alternatives made from almond, oat, cashew or other non-mammalian sources. […] The argument about a dairy-free diet changes completely if consumption of -Gal containing products can contribute to inflammation without giving rise to allergic symptoms.

    The AGS is an allergic disorder that challenges clinical diagnosis due to inapparent presentation and delayed reactions. […] Daily diet counseling, tick bite avoidance or environmental education should be firstly considered in customizing an accurate treatment for the AGS. […] The prevention of tick bites is relevant because continuous exposure to tick bites may maintain or increase anti–Gal IgE titers and lead to allergic responses to previously tolerated foods. […] Avoidance of mammalian meat, by-products of meat (innards), fat (gelatin and lards) and other -Gal-containing foods such as dairy products represent a crucial management strategy for AGS. […] Another major foundation for AGS management is education.

    An ideal diet for alpha-gal syndrome depends on the persons sensitivity and requires some investigation to pinpoint their unique triggers. The first recommendation is to cut out all red meat from the diet, especially porcine and organ meats. Some patients may be able to tolerate dairy, while others cannot. Fatty dairy, such as ice-cream, may be especially problematic. If symptoms still persist, all dairy can be cut out, and other sources of alpha-gal need to be weeded out of the diet, such as gelatin and carrageenan. Additionally, a healthy diet high in nutrients and fiber may be helpful for lowering immune reactivity. […] It is vital to check all ingredients in any medications or supplements you are taking to ensure they do not contain animal products like gelatin. This includes the inactive ingredients, which are readily overlooked, such as magnesium stearate. […] Symptoms may intensify after exercise, during infection, or while menstruating. Certain foods may only become triggers in the presence of these factors. A person with alpha-gal syndrome should not avoid exercising but should rather avoid triggers that do not allow them to exercise safely.

    It is important to remember that random cohorts of subjects in TN, VA, and NC have found that 15% or more of the population have IgE to -Gal. Thus, there must be many subjects who do not experience allergic symptoms despite having the sensitization. […] The risk and also severity of reactions in the -Gal syndrome relates to the amount of the oligosaccharide that is present in food, drugs or other therapeutics. […] There are hundreds of ways in which food and other products which are not obviously mammalian could nonetheless have products from mammals added during preparation or manufacture. […] We are aware that there are some alternative/complementary medical approaches being offered in the community for the treatment of the -Gal syndrome, e.g. auricular acupuncture, kinesiology and others. An interesting possibility is that the apparent efficacy observed in some of these cases actually reflects the natural history of the syndrome, i.e.- -Gal sIgE levels can drop rapidly in some cases.

    The AGS is an allergic disorder that challenges clinical diagnosis due to inapparent presentation and delayed reactions. […] Daily diet counseling, tick bite avoidance or environmental education should be firstly considered in customizing an accurate treatment for the AGS. […] The prevention of tick bites is relevant because continuous exposure to tick bites may maintain or increase anti–Gal IgE titers and lead to allergic responses to previously tolerated foods. […] Avoidance of mammalian meat, by-products of meat (innards), fat (gelatin and lards) and other -Gal-containing foods such as dairy products represent a crucial management strategy for AGS.

    The -Gal syndrome has many novel features that are relevant to diagnosis and management. In general, the diagnosis also dictates the primary treatment, i.e. avoiding mammalian meat and also dairy in some cases. […] Blood levels of IgE to -Gal often drop in patients who avoid recurrent tick bites, but the rate of decline is variable. Similarly, the delay before reactions is variable and the severity of the allergic reactions is not predicted by the delay or the titer of specific IgE. […] The primary advice for newly diagnosed cases of the syndrome is to completely avoid meat of mammals. […] Avoiding products such as milk, yogurt, and ice cream is relatively easy because there are alternatives made from almond, oat, cashew or other non-mammalian sources. […] The argument about a dairy-free diet changes completely if consumption of -Gal containing products can contribute to inflammation without giving rise to allergic symptoms.

    Avoidance of mammalian meat, by-products of meat, fat, and other alpha-gal containing foods such as dairy products is also a critical treatment strategy for AGS. Patients should receive nutrition counseling regarding which foods can trigger allergy. They also need to understand how to attain sufficient calcium, iron, and vitamin B12 in their diet after excluding these foods. […] Symptomatic treatment of an allergy includes antihistamines, corticosteroids, cromolyn-based mast cell stabilizers, antiemetics, and antidiarrheal agents. These are pharmacologic agents that can be prescribed by the health care provider. […] Mammalian meat desensitization by oral immunotherapy (OIT) has been proposed as a promising treatment for AGS. It consists of daily intake of very small and incrementally increasing amounts of allergen in order to reduce the immune response and consequently produce allergen desensitization. However, this procedure has not been sufficiently researched for safe use at this time.

    Alpha-gal syndrome is not a nationally notifiable condition, so states are not required to report their cases of alpha-gal syndrome to the CDC, so our national awareness of case counts is limited to examining lab testing data. […] We did develop a Medscape CME training for health care providers to help increase knowledge around alpha-gal syndrome. […] A key component of preventing alpha-gal syndrome is preventing tick bites, so taking those same actions that we know can prevent Lyme disease, ehrlichiosis, other tick-borne diseases wearing an EPA-approved tick repellent, showering, and checking for ticks when you return inside are really critical. We know that there is no treatment for alpha-gal syndrome and so prevention is especially important.
