Alergiczny nieżyt nosa
Epidemiologia

Alergiczny nieżyt nosa (ANN) jest jednym z najczęstszych przewlekłych schorzeń alergicznych na świecie, z częstością występowania szacowaną na 10-30% populacji globalnej, przy wyraźnych różnicach geograficznych i demograficznych. W USA dotyczy około 7,5% dorosłych (17,6 mln) i 9% dzieci (6,6 mln), natomiast w Europie częstość waha się od 10 do 41% u dorosłych. Choroba najczęściej rozwija się przed 20. rokiem życia, z szczytem zachorowań w drugiej do czwartej dekadzie życia. Występuje charakterystyczna zmiana częstości występowania w zależności od płci – u chłopców przed okresem dojrzewania (stosunek męsko-żeński 1,21), a u kobiet po okresie dojrzewania (stosunek 0,90). Do głównych czynników ryzyka należą wywiad rodzinny atopii, obecność swoistych IgE, ekspozycja na zanieczyszczenia powietrza, dym tytoniowy, a także czynniki socjoekonomiczne i środowiskowe, takie jak zamieszkiwanie w obszarach miejskich czy wyższy status społeczno-ekonomiczny. Uczulenie na roztocze kurzu domowego, alergeny zwierząt domowych, pyłki roślin i grzyby stanowi kluczowy element patogenezy ANN.

Epidemiologia alergicznego nieżytu nosa

Alergiczny nieżyt nosa (ANN) stanowi jedno z najczęstszych przewlekłych schorzeń niezakaźnych na świecie. Choroba ta dotyka znaczącą część populacji globalnej i stanowi istotne obciążenie dla systemu opieki zdrowotnej oraz jakości życia pacjentów. Dokładna analiza epidemiologiczna ANN jest kluczowa dla zrozumienia skali problemu oraz opracowania odpowiednich strategii profilaktycznych i terapeutycznych.12

Występowanie alergicznego nieżytu nosa na świecie

Globalne rozpowszechnienie alergicznego nieżytu nosa jest zróżnicowane i waha się znacząco w zależności od regionu geograficznego, wieku populacji oraz zastosowanych metod badawczych. Według dostępnych danych, częstość występowania ANN na świecie szacuje się na poziomie 10-30% populacji ogólnej.34 Niektóre badania wskazują, że choroba ta może dotykać nawet 10-20% dzieci i 26% dorosłych, a zasięg ten stale rośnie, szczególnie w krajach o niskim i średnim dochodzie.15

Analiza szczegółowych danych epidemiologicznych z różnych regionów świata ukazuje następujący obraz rozpowszechnienia ANN:

  • W Stanach Zjednoczonych – od 7,7% do 30% populacji ogólnej, z czego około 7,5% dorosłych (17,6 miliona) oraz 9% dzieci (6,6 miliona) miało zdiagnozowany ANN67
  • W Europie – według European Community Respiratory Health Survey, częstość występowania waha się od 10 do 41% u dorosłych6
  • W krajach skandynawskich – skumulowana częstość występowania wynosi około 15% u mężczyzn i 14% u kobiet6
  • W Azji – rozpowszechnienie ANN waha się od 27% do 32% wśród dzieci w wieku szkolnym89
  • W Malezji – u dorosłych częstość występowania oszacowano na około 53%, natomiast u uczniów szkół średnich od 11,2% do 55,5% w zależności od regionu10

Międzynarodowe badanie ISAAC (International Study of Asthma and Allergies in Childhood) wykazało, że występowanie objawów rynokonjunktywitis, powiązanych z ANN, waha się od 1,4% do 39,7% wśród dzieci w wieku 13-14 lat na całym świecie.811

Trendy wiekowe i różnice płciowe

Alergiczny nieżyt nosa charakteryzuje się wyraźnymi trendami związanymi z wiekiem i płcią. Badania epidemiologiczne wskazują na następujące prawidłowości:111

  • Częstość występowania ANN rośnie wraz z wiekiem: około 5% u dzieci w wieku 3 lat, 8,5% u dzieci w wieku 6-7 lat, 14,6% u osób w wieku 13-14 lat, osiągając poziom od 11,8% do 46% u osób w wieku 20-44 lat1
  • Szczyt zachorowań przypada na drugą do czwartej dekady życia, po czym następuje stopniowy spadek12
  • W około 80% przypadków ANN rozwija się przed 20 rokiem życia6

Szczególnie interesująca jest dynamika różnic płciowych w występowaniu ANN:11

  • Przed okresem dojrzewania ANN występuje częściej u chłopców niż u dziewcząt (stosunek męsko-żeński 1,21, 95% CI 1,17-1,25 u dzieci poniżej 11 roku życia)13
  • Po okresie dojrzewania trend ten ulega odwróceniu – ANN występuje częściej u kobiet niż u mężczyzn (stosunek męsko-żeński 0,90, 95% CI 0,85-0,95 u osób w wieku 11-18 lat)1314

Przegląd systematyczny i metaanaliza potwierdziły to zjawisko „przełączenia płci” (sex switch) w częstości występowania ANN między dzieciństwem a okresem dojrzewania.1315

Czynniki ryzyka alergicznego nieżytu nosa

Badania epidemiologiczne zidentyfikowały liczne czynniki ryzyka rozwoju alergicznego nieżytu nosa, które można podzielić na kilka głównych kategorii:111

Czynniki genetyczne i demograficzne
  • Wywiad rodzinny w kierunku atopii – jeden z najsilniejszych czynników ryzyka16
  • Płeć męska w dzieciństwie, płeć żeńska po okresie dojrzewania13
  • Obecność swoistych przeciwciał IgE przeciwko alergenom16
  • Poziom IgE w surowicy powyżej 100 IU/mL przed 6 rokiem życia16
  • Rasa i pochodzenie etniczne – w USA dzieci o jaśniejszej skórze częściej doświadczają objawów ANN (10%) w porównaniu z dziećmi o ciemniejszej skórze (7%)7
Czynniki środowiskowe
  • Zanieczyszczenie powietrza (NO2, NO, SO2, cząstki stałe, cząstki spalin diesla)117
  • Ekspozycja na dym tytoniowy – zarówno palenie czynne, jak i bierne17
  • Wczesne wprowadzenie pokarmów stałych lub mieszanek mlecznych16
  • Intensywna ekspozycja na dym papierosowy w pierwszym roku życia16
  • Stosowanie antybiotyków1
Czynniki socjoekonomiczne i styl życia
  • Wyższy status społeczno-ekonomiczny16
  • Zamieszkiwanie w obszarach miejskich i uprzemysłowionych – wyższa częstość występowania ANN w porównaniu z obszarami wiejskimi (do czterokrotnej różnicy)1518
  • Mniejsza liczba dzieci w rodzinie19
  • Wyższy poziom edukacji rodziców19
  • Wyższy dochód gospodarstwa domowego20

Interesującym zjawiskiem jest „efekt farmy” (ang. farm effect) na rozwój alergii. Metaanaliza 8 badań wykazała 40% niższe ryzyko rozwoju ANN u osób, które mieszkały na farmie w pierwszym roku życia.16 Obserwacja ta przyczyniła się do sformułowania „hipotezy higienicznej” oraz późniejszej „hipotezy bioróżnorodności”, sugerujących, że ograniczona ekspozycja na różnorodne mikroorganizmy we wczesnym dzieciństwie może zwiększać ryzyko rozwoju chorób alergicznych.21

Alergeny i uczulenia

Uczulenie na różne alergeny jest kluczowym czynnikiem w rozwoju ANN:22

  • Roztocze kurzu domowego – główna przyczyna ANN w wielu regionach świata10
  • Alergeny zwierząt domowych – szczególnie koty (drugi najważniejszy czynnik wywołujący ANN w Malezji z częstością około 25,4% wśród pracowników biurowych)23
  • Pyłki roślin19
  • Grzyby i pleśnie – wykazano istotny związek między poziomem całkowitego DNA grzybów w osiadłym kurzu a objawami nieżytu nosa wśród malezyjskich uczniów23
  • Insekty22

Obciążenie chorobowe i koszty społeczne

Alergiczny nieżyt nosa, choć sam w sobie nie zagraża życiu (chyba że towarzyszy mu ciężka astma lub anafilaksja), wiąże się ze znaczącą chorobowością i istotnymi konsekwencjami społeczno-ekonomicznymi.24

Wpływ na jakość życia i funkcjonowanie:

  • Około 62% pacjentów z ANN zgłasza znaczący wpływ choroby na codzienne życie25
  • Blisko 80% pacjentów z ANN zgłasza trudności z zasypianiem i zwiększone zmęczenie w ciągu dnia25
  • W badaniach jakości życia pacjenci z istotnym ANN uznali swoje objawy za równie upośledzające, jak objawy u pacjentów z umiarkowaną do ciężkiej astmą26

Wpływ na produktywność i edukację:

  • 3,6% dorosłych opuszcza pracę z powodu ANN, a 36% doświadcza obniżonej wydajności pracy12
  • W USA alergiczny nieżyt nosa przyczynia się do około 2 milionów opuszczonych dni szkolnych, 6 milionów utraconych dni pracy i 28 milionów dni z ograniczoną wydajnością pracy rocznie25
  • Rocznie szacuje się, że z powodu ANN następuje utrata 824 000 dni szkolnych i 4 230 000 dni o obniżonej jakości funkcji życiowych27

Obciążenie ekonomiczne:

  • Koszt ekonomiczny ANN stale rośnie – w USA szacunkowy całkowity koszt leczenia ANN wzrósł z 6,1 miliarda dolarów w 2000 roku do 11,2 miliarda dolarów w 2005 roku24
  • Bezpośrednie koszty leków na receptę przekraczają 6 miliardów dolarów rocznie na całym świecie26
  • Utracona produktywność szacowana jest na 1,5 miliarda dolarów rocznie26
  • Roczne koszty bezpośrednich wydatków zdrowotnych w USA szacuje się na 2-5 miliardów dolarów28
  • Pacjenci samodzielnie leczący się wydają średnio 56 dolarów rocznie26

Współwystępowanie z innymi chorobami

Alergiczny nieżyt nosa często współistnieje z innymi chorobami, co może prowadzić do zwiększonej chorobowości:24

  • Astma – ANN często współwystępuje z astmą i może być związany z zaostrzeniami astmy. Badania przesiewowe w kierunku nieżytu nosa są szczególnie ważne u pacjentów z astmą, ponieważ badania wykazały, że nieżyt nosa występuje u nawet 95% pacjentów z astmą29
  • Zapalenie spojówek alergiczne24
  • Zapalenie ucha środkowego24
  • Dysfunkcja trąbki Eustachiusza24
  • Zapalenie zatok2430
  • Polipy nosa24
  • Atopowe zapalenie skóry24

ANN jest najważniejszym czynnikiem ryzyka rozwoju astmy i zwiększa ryzyko hospitalizacji u dzieci 19-krotnie.8 Badanie MeDALL jako pierwsze ilościowo określiło nadwyżkę współwystępowania astmy, wyprysku i ANN zarówno w obecności, jak i przy braku uczulenia IgE, pokazując, że wielochorobowość nie występuje przypadkowo.31

Regionalne różnice w występowaniu ANN

Częstość występowania alergicznego nieżytu nosa wykazuje znaczne zróżnicowanie geograficzne:6

  • Najwyższa częstość występowania ciężkich objawów ANN u dzieci obserwowana jest w Afryce i Ameryce Łacińskiej24
  • W USA stany zachodnie mają najwyższą częstość występowania ANN (stanowiącą 36% całkowitej częstości występowania w USA), a stany północno-wschodnie najniższą (18%)32

Według danych z 2020 roku, całkowita liczba przypadków ANN w siedmiu głównych rynkach (7MM: USA, Niemcy, Francja, Włochy, Hiszpania, Wielka Brytania i Japonia) wynosiła 188,40 miliona i oczekuje się, że będzie rosnąć w okresie 2018-2030.33

Rozkład przypadków ANN w poszczególnych krajach (dane z 2020 r.):34

  • Japonia – 59,29 miliona przypadków (najwyższa liczba w 7MM)
  • Stany Zjednoczone – 52,26 miliona przypadków
  • Kraje UE-5 (Niemcy, Francja, Włochy, Hiszpania, Wielka Brytania) – łącznie 76,86 miliona przypadków

Nadzór i monitorowanie epidemiologiczne

Monitoring epidemiologiczny ANN obejmuje różne metody i wskaźniki:33

  • Całkowita liczba przypadków choroby
  • Przypadki zdiagnozowane
  • Przypadki związane z określonymi grupami wiekowymi
  • Przypadki związane z określonymi alergenami
  • Przypadki leczone

Badania monitorujące, takie jak przeprowadzone w mieście w południowej Brazylii w latach 2011-2018, pokazują dynamikę zmian w częstości występowania ANN. W tym konkretnym badaniu zaobserwowano znaczący spadek zgłaszanego obecnego nieżytu nosa (z 63,3% do 50,5%), rynokonjunktywitis (z 48,9% do 38,8%) i kataru siennego (z 52,0% do 43,3%).3536

Nowe metody nadzoru epidemiologicznego wykorzystują technologie mobilne i sztuczną inteligencję (AI) do zbierania danych rzeczywistych (real-world data) i przewidywania występowania ANN:3137

  • AI może przewidywać ANN na podstawie danych o zanieczyszczeniu (NO, PM10); model Random Forest osiągnął AUC wynoszące 0,84
  • Głębokie uczenie prognozuje również dzienne przypadki ANN na podstawie trendów zanieczyszczenia
  • Modele wspomagają również diagnostykę ANN przy użyciu danych klinicznych i wykrywają polipy nosa z dokładnością 98,3%

Podsumowanie i perspektywy

Alergiczny nieżyt nosa stanowi istotne wyzwanie dla systemów opieki zdrowotnej na całym świecie. Jego wysoka częstość występowania, znaczący wpływ na jakość życia oraz istotne koszty ekonomiczne czynią go ważnym problemem zdrowia publicznego.111

Przyszłe badania epidemiologiczne powinny koncentrować się na:2138

  • Ocenie i dopracowaniu hipotez dotyczących przyczyn ANN, biorąc pod uwagę zmianę paradygmatu od uczulenia atopowego do dysfunkcji barierowej
  • Integracji genomiki, transkryptomiki, proteomiki i metabolomiki w badaniu patogenezy ANN, co przyczyni się do lepszego zrozumienia interakcji między czynnikami środowiskowymi, uczuleniem na alergeny i rozwojem choroby
  • Poszukiwaniu biomarkerów umożliwiających przewidywanie odpowiedzi na leczenie i dostosowanie postępowania u pacjentów z ANN
  • Badaniu wpływu zmian klimatycznych na zaostrzenia nieżytu nosa15
  • Przeprowadzeniu badań podłużnych, szczególnie w krajach o niskim i średnim dochodzie, w celu zbadania ekspozomów związanych z ANN17

Dokładne monitorowanie epidemiologii alergicznego nieżytu nosa pozostaje kluczowe dla opracowania skutecznych strategii profilaktycznych, diagnozowania i leczenia tej powszechnej choroby alergicznej.1

  • #1 Epidemiology, Prevention and Clinical Treatment of Allergic Rhinitis: More Understanding, Better Patient Care
    https://pmc.ncbi.nlm.nih.gov/articles/PMC9605427/
    Allergic rhinitis (AR) is highly prevalent worldwide, and the clinical management of AR is yet to be improved. Thus, AR imposes significant burden on individuals and society. With regards to the epidemiology of AR, factors such as prevalence, disease classification, allergen sensitization, co-morbidities, risk factors, genetic susceptibility, and costs, etc., are widely discussed. Globally, the prevalence of AR remains increasing, particularly in low- and middle-income countries, and ranges from 1.0% to 54.5%. The prevalence of AR is roughly 5% in children by 3 years of age, increases with age from 8.5% of 67 year-olds to 14.6% of 13-14 year-olds, and reaches more than 11.8% to 46% in people aged 20-44. Notably, the incidence of AR is higher in males than in females before puberty, but this trend reverses after puberty. A number of risk factors for AR have been identified including antibiotic use, air pollution, and maternal and paternal smoking. Epidemiological studies on the risk and protective factors of AR in the context of genetic susceptibility and epigenetic modification have produced a lot of evidence. Future epidemiological studies are needed to evaluate and refine these hypotheses given the paradigm shift from atopic sensitization to barrier dysfunction.

  • #11 Epidemiology, Prevention and Clinical Treatment of Allergic Rhinitis: More Understanding, Better Patient Care
    https://www.mdpi.com/2077-0383/11/20/6062
    Allergic rhinitis (AR) is a noninfectious inflammatory disease of the nasal mucosa mediated by IgE after atopic individuals are exposed to inhaled allergens and involving a variety of immune cells and cytokines. AR is highly prevalent worldwide, and the clinical management of AR is yet to be improved. Thus, AR imposes significant burden on individuals and society. This editorial will focus on recent advances on the epidemiology, prevention, and clinical management of AR, as well as future research directions. […] With regards to the epidemiology of AR, factors such as prevalence, disease classification, allergen sensitization, co-morbidities, risk factors, genetic susceptibility, and costs, etc., are widely discussed. Globally, the prevalence of AR remains increasing, particularly in low- and middle-income countries, and ranges from 1.0% to 54.5%. The prevalence of AR is roughly 5% in children by 3 years of age, increases with age from 8.5% of 6–7 year-olds to 14.6% of 13-14 year-olds, and reaches more than 11.8% to 46% in people aged 20–44. Notably, the incidence of AR is higher in males than in females before puberty, but this trend reverses after puberty. A systematic review and meta-analysis showed that in children less than 11 years of age, significantly more boys than girls exhibited rhinitis symptoms (male–female ratio 1.21, 95% CI 1.17–1.25), whereas in adolescents (11 to 18 years of age), males were significantly less affected than females (male–female ratio 0.90, 95% CI 0.85–0.95). A number of risk factors for AR have been identified including antibiotic use, air pollution, and maternal and paternal smoking.

    Allergic rhinitis (AR) is an atopic disease characterized by symptoms of nasal congestion, clear rhinorrhea, sneezing, postnasal drip, and nasal pruritis. It affects one in six individuals and is associated with significant morbidity, loss of productivity, and healthcare costs. […] The prevalence of allergic rhinitis based on physician diagnosis is approximately 15%; however, the prevalence is estimated to be as high as 30% based on patients with nasal symptoms. AR is known to peak in the second to fourth decades of life and then gradually decline. […] According to data from the International Study for Asthma and Allergies in Childhood, 14.6% in the 13 to 14 year age group and 8.5% in the 6 to 7 year age group display symptoms of rhinoconjunctivitis linked to allergic rhinitis. […] A systematic review from 2018 estimated that 3.6% of adults had missed work, and 36% had impaired work performance due to allergic rhinitis. Economic evaluations have shown that indirect costs associated with lost work productivity account for the majority of the cost burden for AR.

    Risk factors for developing AR include a family history of atopy, male sex, a presence of allergen-specific IgE, a serum IgE greater than 100 IU/mL before age 6, and higher socioeconomic status. […] Studies in young children have shown a higher risk of AR in those with an early introduction to foods or formula and/or heavy exposure to cigarette smoking in the first year of life. […] There is a growing interest in the „farm effect” on the development of allergies, and a meta-analysis of 8 studies showed a 40% lower risk in subjects who had lived on a farm during their first year of life.

    Epidemiological studies on the risk and protective factors of AR in the context of genetic susceptibility and epigenetic modification have produced a lot of evidence. Two major observations regarding the cause of AR are the ‘sibling effect’ and the ‘farm effect’, which lead to the ‘hygiene hypothesis’ and, later, the ‘biodiversity hypothesis’. Future epidemiological studies are needed to evaluate and refine these hypotheses given the paradigm shift from atopic sensitization to barrier dysfunction.

    Rhinitis is one of the most common chronic conditions for which medical care is sought. Allergic rhinitis is an IgE-mediated disorder of the nose caused by the interaction of airborne allergens with specific IgE type antibodies on the surface of mast cells. Over 400 million people suffer from allergic rhinitis around the world, which to a large extent remains underdiagnosed and undertreated. In the United States it affects between 10-30% of the adult general population and up to 40% of children, making it the fifth most common chronic disease. Unfortunately, the health and economic impact of allergic rhinitis historically has been grossly underestimated and it is only recently that rhinitis has been recognized as a serious issue with epidemic proportions. In the U.S., allergic rhinitis contributes to approximately 2 million missed school days, 6 million lost work days and 28 million restricted work days annually. The burden of rhinitis in the US adult population is estimated between 10-30%. Standardized quality of life measures has found that in 62% of patients with allergic rhinitis, the disease has a significant impact on their daily life. Studies have also shown that almost 80% of patients with allergic rhinitis report difficulty sleeping and thus increased daytime fatigue.

Patients with AR felt they were equally impaired and unable to participate in the activities of normal living similar to those with the moderate-to-severe asthma. […] The financial cost of AR is difficult to estimate. Self-treating patients are estimated to spend an average of 56 dollars per year. The direct cost of prescription medication exceeds 6 billion dollars per year worldwide, and lost productivity is estimated at 1.5 billion dollars per year.

In a report from the Pollution and Asthma Risk: an Infant Study (PARIS), 9.1% of the 1859 toddlers in the study cohort reported allergic rhinitis-like symptoms at age 18 months. […] Mortality is not associated with allergic rhinitis (AR), but significant morbidity occurs. Morbidity is manifested in several ways. Annually, an estimated 824,000 school days are missed, and an estimated 4,230,000 days of reduced quality-of-life functions are reported.

    Allergen avoidance, drug therapy and allergy immunotherapy (AIT) are the main clinical intervention modalities for AR. The first-line treatments for AR include H1 antihistamines, intranasal corticosteroids (INCS) and a combination of INCS and H1 antihistamines, depending on the severity of the patients symptoms. AIT is considered as the only etiological and most effective therapy for AR. However, AIT has a number of limitations, including high cost, systemic side effects, the long treatment period and the absence of biomarkers to monitor and predict therapeutic efficacy. There are several items that should be addressed in future research efforts for AR. First, to integrate genomics, transcriptomics, proteomics and metabolomics into AR pathogenesis investigation will promote the understanding of the interactions between environmental factors, allergen sensitization and disease development. Second, biomarkers are urgently needed to predict treatment response and tailor the management of AR patients.
