Patofizjologia i mechanizm

Geograficzny język (benign migratory glossitis) to przewlekłe, zapalne schorzenie błony śluzowej jamy ustnej, charakteryzujące się nawracającymi, czerwonymi, gładkimi plamami na języku, otoczonymi białymi liniami, wynikającymi z utraty brodawek nitkowatych. Patogeneza obejmuje podwyższone poziomy mediatorów zapalnych, takich jak IL-8 i kalprotektyna ślinowa, a histopatologicznie obserwuje się hiperkeratozę, akantozę, migrację neutrofili i mikroropnie podrogowe, podobne do zmian w łuszczycy krostkowej. Schorzenie wykazuje genetyczne uwarunkowanie, związek z antygenami HLA (m.in. HLA-DR5, HLA-DRW6, HLA-Cw6) oraz mutacjami w genie IL36RN. Zaburzenia cyklu złuszczania i keratynizacji nabłonka prowadzą do powstawania charakterystycznych zmian, które mogą rozprzestrzeniać się według modelu dynamicznego, obejmującego fale zapalenia i regeneracji nabłonka.

Patogeneza i mechanizm geograficznego języka

Geograficzny język (benign migratory glossitis, erythema migrans) jest łagodnym przewlekłym zapalnym schorzeniem błony śluzowej jamy ustnej, charakteryzującym się nawracającymi zmianami o nieznanej etiologii. Na języku pojawiają się czerwone, mapopodobne, gładkie i obrzęknięte plamy otoczone białymi liniami, które powstają w wyniku utraty brodawek nitkowatych (papillae) na powierzchni języka.12 Chociaż dokładna patogeneza tego schorzenia pozostaje nieznana, zaproponowano kilka teorii wyjaśniających mechanizm powstawania zmian.

Mechanizm zapalny

Geograficzny język jest schorzeniem o podłożu zapalnym. Badania wykazały podwyższone poziomy mediatorów zapalnych, szczególnie IL-8, co przyczynia się do ostrej odpowiedzi zapalnej.1 Innym mediatorem zapalnym potencjalnie zaangażowanym w patogenezę jest kalprotektyna ślinowa.1 Histopatologicznie, geograficzny język charakteryzuje się hiperkeratozą, akantozą, wydłużonymi wypustkami nabłonka i migracją neutrofili, co prowadzi do tworzenia mikroropni podrogowych przypominających zmiany obserwowane w łuszczycy krostkowej.12

Badania histopatologiczne ujawniają ostry i przewlekły naciek zapalny w podśluzówce z obrzękiem nabłonka. Komórki zapalne gromadzą się w najwyższych warstwach nabłonka i tworzą mikroropnie.1 W przeciwieństwie do niektórych teorii sugerujących związek z infekcją grzybiczą lub bakteryjną, nie stwierdzono konsekwentnego powiązania z konkretnym mikroorganizmem.12

Podłoże genetyczne

Istnieją dowody na genetyczne uwarunkowanie geograficznego języka. Badania wykazały, że schorzenie to często występuje rodzinnie, co sugeruje dziedziczny charakter.12 Sugeruje się wielogenowy model dziedziczenia, a występowanie geograficznego języka u rodzeństwa rodzica dotkniętego tym schorzeniem oraz u bliźniąt jednojajowych potwierdza genetyczną etiologię.1

Badania genetyczne wykazały związek z określonymi antygenami leukocytów ludzkich (HLA), w tym zwiększoną częstość występowania HLA-DR5, HLA-DRW6 i HLA-Cw6 oraz zmniejszoną częstość występowania HLA-B51.1 Niedawne badania wykazały, że mutacje w genie IL36RN są związane z geograficznym językiem, przy czym mutacja ta została wykryta w trzech pokoleniach rodziny z tym schorzeniem.123

Zaburzenia procesu keratynizacji

Geograficzny język charakteryzuje się zaburzeniem normalnego cyklu wymiany brodawek nitkowatych na powierzchni języka.1 Patogeneza schorzenia wiąże się z procesami złuszczania i keratynizacji nabłonka. W warunkach prawidłowych tempo złuszczania komórek nabłonkowych jest takie samo jak tempo odnawiania warstwy podstawnej nabłonka błony śluzowej jamy ustnej.1

Geograficzny język pojawia się, gdy tempo złuszczania komórek nabłonkowych jest szybsze, co prowadzi do zmniejszenia ilości dojrzałej keratyny i rozwoju owrzodzeń.1 Zmiany na języku powstają, gdy stara powierzchnia języka nie odnawia się równomiernie. W niektórych miejscach warstwa nabłonka złuszcza się zbyt wcześnie, pozostawiając czerwone, bolesne obszary, podczas gdy w innych miejscach nabłonek utrzymuje się zbyt długo i wygląda na biały.1

Modele fizyczne

Fizycy zaproponowali dynamiczny model systemowy wyjaśniający ewolucję i nasilenie geograficznego języka.1 Według tego modelu, rozprzestrzenianie się zmian na języku może zachodzić na dwa różne sposoby:

  1. Brodawki stają się zapalne, a następnie ulegają zniszczeniu, gdy zmiany rozprzestrzeniają się jak fala. Kolejna fala nie pojawi się, dopóki brodawki nie zaczną odrastać.1
  2. Zmiany mogą rozwijać się przez formowanie się wzorców spiralnych, które ewoluują w regionach języka, które wciąż się regenerują, powodując ponowne pobudzenie danego obszaru. To samopodtrzymujące się pobudzenie regenerujących się regionów prowadzi do bardziej ostrego stanu, który będzie utrzymywał się przez stosunkowo długi czas.12

Model komórkowego automatu sugeruje, że rozprzestrzenianie się wzorców spiralnych prowadzi do ciągłego, samopodtrzymującego się pobudzenia regenerujących się regionów, co może prowadzić nabłonek przez kolejne cykle regeneracji i pobudzenia, zanim powróci do stabilnego, wyleczonego stanu.1

Związek z łuszczczyą

Jedną z najsilniej udokumentowanych teorii dotyczących patogenezy geograficznego języka jest jego związek z łuszczycą. Ze względu na podobieństwa kliniczne, histopatologiczne i immunohistochemiczne między geograficznym językiem a łuszczycą, niektórzy eksperci uważają geograficzny język za ustną manifestację łuszczycy.12

Geograficzny język występuje częściej u pacjentów z łuszczycą, szczególnie u tych z łuszczycą krostkową. Histopatologicznie oba schorzenia wykazują hiperkeratozę, akantozę, wydłużone wypustki nabłonka i obecność mikropustulacji Munro.1 Geograficzny język opisywano jako wczesny objaw łuszczycy, z późniejszą ewolucją w kierunku wariantu z bruzdami, który może być trwały i/lub współistnieć z geograficznym językiem nawet u 34,5% dotkniętych pacjentów.1

Obecność geograficznego języka u pacjenta bez łuszczycy wskazuje na zwiększone prawdopodobieństwo rozwoju uogólnionej łuszczycy krostkowej.1 Geograficzny język może być wyrazem łuszczycy o charakterze przejściowym, podczas gdy język bruzdowany może być późniejszym, bardziej trwałym wyrazem łuszczycy.1

Czynniki immunologiczne i związek z chorobą atopową

Badania wykazały związek między astmą, egzemą, katarem siennym, alergicznym nieżytem nosa, pacjentami z wyższym poziomem immunoglobuliny E a geograficznym językiem.12 Atopowe zapalenie skóry jest nawracającą przewlekłą zapalną chorobą skóry związaną z innymi chorobami atopowymi, takimi jak alergiczny nieżyt nosa i astma.1

Ta asocjacja może wynikać z istnienia czynników psychosomatycznych, które przyczyniają się do obu patologii.1 Badania powiązały obecność alergii z geograficznym językiem, sugerując, że alergia lub atopia mogą być warunkami leżącymi u podstaw wystąpienia tego schorzenia.1

Czynniki hormonalne

Hormony również zostały zaproponowane jako czynniki odgrywające rolę w patogenezie geograficznego języka.12 Zaburzenia hormonalne, w tym stosowanie doustnych środków antykoncepcyjnych, mogą przyczyniać się do rozwoju tego schorzenia.12

Geograficzny język może rozwijać się podczas ciąży lub menopauzy, gdy hormony ulegają znacznym wahaniom.1 Kobiety stosujące doustne środki antykoncepcyjne mają poważne zaburzenia równowagi hormonalnej, które mogą prowadzić do rozwoju geograficznego języka.1

Niedobory żywieniowe

Niedobory witaminy D, B6, B12, kwasu foliowego, żelaza i cynku również zostały zaproponowane jako czynniki odgrywające rolę w patogenezie geograficznego języka.12 Osoby z niedoborem witaminy B są bardziej narażone na stany zapalne, obrzęki i inne objawy na języku.1

Osoby z niedoborem witaminy B są bardziej podatne na łyse obszary na języku.1 Ponieważ istnieje związek między niedoborem żelaza i witamin z grupy B a uogólnionym zapaleniem języka z zanikiem brodawek, zaproponowano możliwy związek między geograficznym językiem a niedoborami żywieniowymi.1

Związek z innymi schorzeniami

Geograficzny język był również wiązany z innymi schorzeniami, takimi jak:

  • Cukrzyca typu 1 – lekarze zidentyfikowali, że pacjenci z cukrzycą mają zwiększoną częstość występowania geograficznego języka, szczególnie w przypadku cukrzycy typu 112
  • Zespół Reitera – geograficzny język był wiązany z reaktywnym zapaleniem stawów12
  • Choroba Downa1
  • Liszaj płaski1
  • Choroba trzewna – może obejmować jamę ustną1
  • Koronawirus (COVID-19) – geograficzny język może pojawiać się wraz z początkiem regularnych objawów COVID-19, co prawdopodobnie wiąże się z podwyższonym poziomem IL-61

Czynniki ochronne

Interesującym aspektem patogenezy geograficznego języka jest to, że używanie tytoniu wykazało działanie ochronne w rozwoju tego schorzenia.12 Geograficzny język występuje odwrotnie proporcjonalnie do palenia papierosów i używania tytoniu.12 Warunek wydaje się być rzadszy u palaczy.1

Czynniki psychologiczne

Stres emocjonalny i problemy psychologiczne mogą zaostrzać objawy i przedłużać czas trwania lub powodować nawroty geograficznego języka.1 Badania donoszą o stresie i depresji jako czynnikach związanych z pojawieniem się zmian.1

Niedawne badania wykazały związek geograficznego języka z obecnością lęku, stresu i depresji.1 Młodsi pacjenci byli bardziej podatni na stres i, w konsekwencji, wykazywali zaostrzenie zmian w jamie ustnej związanych z geograficznym językiem.1

Żywność i czynniki środowiskowe

Ostra żywność lub chili może wpływać na kubki smakowe, powodować alergie i wywoływać geograficzny język.1 Geograficzny język może być wywołany przez podrażnienie gorącymi lub pikantnymi potrawami lub alkoholem.1

Identyfikacja czynników ryzyka, takich jak chili jako alergen, odgrywa ważną rolę w diagnozowaniu i zapewnianiu odpowiedniej terapii pacjentom z objawowym geograficznym językiem.1 Biorąc pod uwagę, że objawy mogą się nasilać wraz z niektórymi pokarmami, takimi jak kwaśne, bardzo pikantne lub gorące potrawy, zaleca się uważne monitorowanie występowania geograficznego języka i identyfikację potencjalnych czynników wyzwalających.1

Podsumowanie patogenezy

Geograficzny język pozostaje enigmatycznym schorzeniem o złożonej i wieloczynnikowej patogenezie. Chociaż dokładna przyczyna pozostaje nieznana, dowody wskazują na interakcję między czynnikami genetycznymi, immunologicznymi, hormonalnymi i środowiskowymi. Najsilniejsze dowody łączą to schorzenie z łuszczycą, sugerując wspólne podstawy patogenetyczne.

Mechanizm zapalny, zaburzenia procesu keratynizacji oraz modele dynamiki rozprzestrzeniania się zmian pomagają wyjaśnić charakterystyczne cechy kliniczne geograficznego języka. Przyszłe badania, szczególnie w zakresie genetyki i immunologii, mogą dostarczyć głębszego zrozumienia tego schorzenia i potencjalnie prowadzić do bardziej ukierunkowanych interwencji terapeutycznych.1

    Geographic tongue (GT) is a benign oral mucosal lesion that usually affects the dorsal and lateral surfaces of the tongue. […] The etiology for GT is unknown. However, a number of etiological factors have been suggested. A hereditary tendency had been reported in previous studies investigating siblings of a parent affected by GT while a more recent study of 5-year-old monozygotic twins with GT supported a genetic etiology. […] While the etiology of GT remains unknown, recent studies have revealed varying insights into the pathophysiology of this inflammatory disease. Levels of the inflammatory mediator, IL-8, are increased among individuals with GT, and is thought to contribute to the acute inflammatory response. […] Another study demonstrated that salivary calprotectin may be involved in the pathogenesis of GT. […] Discussions regarding genetic implications in the pathophysiology of GT have also been explored. A mutation in the IL36RN gene was detected in a three-generational family with GT alone.

    Geographic tongue, also known as benign migratory glossitis, is a benign chronic inflammatory condition of the tongue. It is characterized by erythematous lesions with filiform papillae atrophy, surrounded by white limited areas in the dorsal and lateral aspects of the tongue, producing a map-like aspect. This lesions change in size and shape with time, and are characterized by periods of exacerbation and remission without scaring. The cause is unknown, but multiple associations have been described, which will be discussed below. […] Although the cause of geographic tongue is still unknown, most patients report family history of the condition, suggesting then a possible genetic predisposition. Prevalence of this condition among parents and siblings of these patients is significantly higher than general population.

    https://oasisderm.com/geographic-tongue-2/
    Geographic tongue, also known as benign migratory glossitis, is a relatively common, non-serious condition affecting the surface of the tongue. Characterized by the loss of papillae(bumps on the tongue) in certain areas, it creates smooth, red patches that often have a map-like appearance. […] The exact cause of geographic tongue remains unclear, though several factors may contribute to its development. One prominent hypothesis is that the condition arises from a dysfunction in the normal turnover of the filiform papillae, which are the small, keratinized projections on the tongues surface. In geographic tongue, areas of the tongue lose these papillae, resulting in the formation of smooth, erythematous(red) patches. […] Research indicates that patients with a history of psoriasis are more likely to develop geographic tongue, suggesting a potential genetic or immune-mediated link between the two conditions. […] Although the exact etiology remains unclear, geographic tongue is often associated with other dermatologic conditions such as psoriasis and fissured tongue.

    Geographic tongue (GT) is a chronic tongue condition triggered by various factors such as immune reactions, allergies, stress, hereditary factors, and nutritional deficiencies. […] Spicy foods or chili can affect the taste buds, cause allergies, and trigger GT. […] The etiology of GT is still unknown. Predisposing factors associated with GT include genetic factors, immune reactions, allergies, hormonal disorders, pregnancy, emotional stress, nutritional deficiencies, and drugs. […] Allergies or atopy may be conditions underlying the occurrence of GT, as in this patient. […] The pathogenesis of GT is related to epithelial turnover through desquamation and keratinization processes. […] The rate of desquamation of epithelial cells is typically the same as that of the basal layer of the epithelial lining of the oral mucosa. GT occurs due to the faster rate of desquamation of epithelial cells, resulting in a decrease in mature keratin and developing into ulcers.

    Geographic tongue is a common condition. […] It happens because of the way the old’ surface of the tongue replaces itself. The top layer of the 'skin’ of the tongue does not come away evenly. In some parts the 'skin’ comes away too early and so leaves a red, sore area like a scratch on the skin. In other places the skin stays on too long and looks white. […] The red areas, because they are thin, can sometimes become infected with thrush (candida) and so feel sore. Thrush is very common in mouths. […] Geographic tongue will never become cancerous, but you will have to learn to live with it.

    A spiral series of self-sustaining cycles of excitation underlies the puzzling condition known geographic tongue, physicists suggest. […] The condition affects about 2% of the population, but its exact cause is unknown. […] Utilizing a dynamical systems approach (i.e., a mathematical description of the dynamical aspect of the condition) allows one to get an insight regarding the evolution and severity of the geographic tongue (GT) condition. […] Dr. Seiden and Dr. Sofia Curland from Max Planck Institute for the Physics of Complex Systems in Dresden, Germany, saw similarities between the dynamic appearance of the tongue with phenomena observed in such excitable media as forest fires, cardiac arrhythmias, chemically driven reaction-diffusion systems, and morphogenesis in multicellular organisms.

    Geographic tongue (also referred to as „lingua geographica”) is not a disease but merely a benign variation in appearance of the top of the tongue. Inflammation spreads in the form of smooth, red irregularly shaped lesions on your tongue, usually with slightly raised edges and white borders that resemble small islands and give the tongue a map-like, or geographic, appearance. […] Geographic tongue raises many questions: Currently, the causes of this condition remain unclear, and its course is unpredictable and varies significantly. To shed light on this mysterious tongue condition, physicists from Israel have studied how the patches move from a mathematical-physical perspective. In doing so, they discovered that geographic tongue can spread in two different ways. […] With the first type, the papillae become inflamed and then destroyed when the patches spread like a wave. Once the papillae have been destroyed, the next wave will not appear until they have started to regrow.

    In the second type, the patches can develop through the formation of spiral patterns that evolve into regions of the tongue that are still recovering, thus causing that particular region to be excited again. This self-sustaining excitation of recovering regions results in a more acute condition that will linger for a relatively long period of time. […] The exact cause of geographic tongue is not yet known. However, it has been noted that the disorder tends to run in families. […] Emotional stress and psychological issues exacerbate the symptoms and prolong the duration or cause the recurrence of geographic tongue.

  • #1 Physicists Zero In on Mechanism behind
    https://www.scientificamerican.com/article/physicists-zero-in-on-mechanism-behind-geographic-tongue-condition/
    According to their cellular automaton model, propagation of spiral patterns results in a continuous, self-sustaining excitation of recovering regions, which can force the epithelium through successive reentry cycles of rest and excitation before it can settle back into its stable, healed state. […] This model would account for the presence of multiple lesions of different sizes expanding on the epithelium simultaneously and merging upon contact, thus leading to highly irregular patterns. […] Open ended patterns — in particular spirals — tend to be self-sustaining and thus, from a theoretical point of view, will linger for longer periods of time. […] We do not know exactly how spiral patterns form in GT patients (due to lack of careful clinical studies on the initiation and evolution of different patterns).

    According to their cellular automaton model, propagation of spiral patterns results in a continuous, self-sustaining excitation of recovering regions, which can force the epithelium through successive reentry cycles of rest and excitation before it can settle back into its stable, healed state. […] This model would account for the presence of multiple lesions of different sizes expanding on the epithelium simultaneously and merging upon contact, thus leading to highly irregular patterns. […] Open ended patterns — in particular spirals — tend to be self-sustaining and thus, from a theoretical point of view, will linger for longer periods of time. […] We do not know exactly how spiral patterns form in GT patients (due to lack of careful clinical studies on the initiation and evolution of different patterns).
