Pylica krzemowa
Epidemiologia

Pylica krzemowa (silicosis) jest najczęstszą formą pylicy płuc, stanowiącą około 90% wszystkich przypadków na świecie, wywołaną inhalacją krystalicznej krzemionki w przemyśle budowlanym, górnictwie i produkcji materiałów budowlanych. W 2017 roku odnotowano 23 695 nowych przypadków (standaryzowany wiekowo współczynnik zapadalności ASIR 0,30/100 000), a roczna liczba zgonów przekracza 12 900. Epidemiologia wykazuje znaczne zróżnicowanie geograficzne, z najwyższą zapadalnością w regionie Wschodniej Azji (ASIR 0,78/100 000) oraz rosnącą liczbą przypadków w Afryce i Ameryce Południowej. W Polsce w latach 2000-2019 zgłoszono 2066 potwierdzonych przypadków pylicy krzemowej, stanowiących 12,8-21,2% wszystkich pylic płuc. Szczególnie niepokojąca jest nowa epidemia wśród pracowników obróbki kamienia sztucznego, gdzie 95% badanych było narażonych na suchą obróbkę, co znacząco zwiększa ryzyko rozwoju choroby. Diagnostyka opiera się na badaniach przesiewowych, jednak konwencjonalne zdjęcia rentgenowskie mają ograniczoną wartość w wykrywaniu wczesnych stadiów, co podkreśla potrzebę stosowania tomografii komputerowej wysokiej rozdzielczości (HRCT).

Epidemiologia pylicy krzemowej

Pylica krzemowa (silicosis) stanowi najczęstszą postać pylicy płuc, odpowiadając za około 90% wszystkich przypadków pylicy na świecie i stanowi poważny problem zdrowia publicznego 12. Jest to nieuleczalna choroba płuc wywołana wdychaniem krystalicznej krzemionki występującej w różnych gałęziach przemysłu, takich jak budownictwo, górnictwo, odlewnictwo i produkcja materiałów budowlanych 34.

Globalne rozpowszechnienie pylicy krzemowej

Według Globalnego Badania Obciążenia Chorobami (Global Burden of Disease, GBD) z 2019 roku, globalna liczba nowych przypadków pylicy krzemowej wzrosła o 64,6% w latach 1990-2019, a chorobowość o 91,4% 56. W 2017 roku zidentyfikowano 23 695 nowych przypadków pylicy krzemowej (standaryzowany wiekowo współczynnik zapadalności 0,30 na 100 000), co stanowi 39% wszystkich przypadków pylicy płuc 7. Równocześnie liczba zgonów związanych z pylicą krzemową na świecie szacowana jest na ponad 12 900 rocznie 8.

Mimo wzrostu bezwzględnej liczby przypadków, standaryzowane wiekowo wskaźniki (ASR) wykazały ogólną tendencję spadkową w latach 1990-2019, ze średnim rocznym procentowym spadkiem na poziomie 0,5% dla zapadalności i 2,0% dla wskaźnika DALY (utraconych lat życia skorygowanych niepełnosprawnością) 9. Najwyższe obciążenie chorobą występuje w regionach o średnim i średnio-wysokim wskaźniku rozwoju społeczno-demograficznego (SDI) 10.

Regionalne zróżnicowanie występowania

Epidemiologia pylicy krzemowej wykazuje znaczne zróżnicowanie geograficzne:

  • Azja: Region Wschodniej Azji miał najwyższy standaryzowany wiekowo współczynnik zapadalności (ASIR) wynoszący 0,78 na 100 000. W 2017 roku liczba nowych przypadków pylicy krzemowej wynosiła: Wschodnia Azja – 15 980, Południowo-Wschodnia Azja – 656, Azja Centralna – 18, Południowa Azja – 2 823 11. W Chinach około 23 miliony pracowników jest narażonych na krzemionkę 12.
  • Afryka: Pylica krzemowa stanowiła 32% wszystkich pylic płuc, a liczba nowych przypadków wzrosła o 124% w latach 1990-2017 13.
  • Europa: GBD wykazało zmniejszającą się tendencję w zapadalności na pylicę krzemową od 1990 do 2017 (ASIR: 0,33 vs. 0,20 w Europie Środkowej, 0,09 vs. 0,07 w Europie Wschodniej, 0,12 vs. 0,04 w Europie Zachodniej) 14. W Wielkiej Brytanii odnotowano 95 przypadków pylicy krzemowej w 2007 roku i 85 w 2008 roku, a także 14 zgonów w 2006 roku i 7 w 2007 roku 15.
  • Ameryka Północna: W Stanach Zjednoczonych ponad 2 miliony pracowników jest narażonych na krzemionkę, z czego 1,7 miliona pracuje poza górnictwem. Według NIOSH (National Institute for Occupational Safety and Health) każdego roku u 1500-2360 osób rozwinie się pylica krzemowa 1617.
  • Australia i Nowa Zelandia: GBD wskazało ASIR na poziomie 0,06 w Australii i 0,07 w Nowej Zelandii w 2017 roku 18.

W Polsce w latach 2000-2019 zgłoszono 2066 potwierdzonych przypadków pylicy krzemowej i 10 665 przypadków innych pylic płuc. Pylica krzemowa stanowiła 12,8-21,2% wszystkich przypadków pylicy płuc. Liczba potwierdzonych przypadków pylicy krzemowej w Polsce zmniejszyła się w tym okresie, ale choroba nadal pozostaje istotnym problemem zdrowotnym 19.

Epidemie pylicy krzemowej

Na przestrzeni lat odnotowano kilka epidemii pylicy krzemowej:

  • Najgorsza epidemia miała miejsce w latach 1930-1931 podczas budowy tunelu Gauley Bridge w Zachodniej Wirginii, gdzie ponad 400 z szacowanych 2000 pracowników zmarło na pylicę krzemową, a prawie wszyscy pozostali rozwinęli tę chorobę 2021.
  • W 1996 roku pylicę krzemową stwierdzono u 60 z 1072 pracowników fabryki motoryzacyjnej. Ryzyko rozwoju choroby wzrastało wraz z liczbą lat ekspozycji 22.
  • Ostatnio obserwuje się nową epidemię pylicy krzemowej wśród młodych pracowników produkujących blaty z kamienia sztucznego (kwarcowego) w Kalifornii i w krajach takich jak Australia, Izrael i Hiszpania 23.

Pierwszy przypadek pylicy krzemowej związany z produkcją kamienia sztucznego zidentyfikowano w Teksasie w 2014 roku. Od tego czasu inne stany odkryły więcej przypadków pylicy krzemowej u pracowników zajmujących się obróbką kamienia sztucznego 24. Badania przesiewowe w branży obróbki kamienia wykazały bardzo wysokie ryzyko pylicy krzemowej, przy czym 95% przebadanych pracowników pracowało z kamieniem sztucznym, a 86,2% było narażonych na obróbkę kamienia na sucho 25.

Systemy nadzoru nad pylicą krzemową

Mimo że pylica krzemowa jest jedną z najstarszych opisanych chorób płuc, występowanie ponad 20 000 nowych przypadków rocznie wskazuje, że choroba ta nadal stanowi poważny problem. Szczególnie niepokojąca jest wysoka zapadalność w regionach Azji, Afryki i Ameryki Południowej, a niedawne pojawienie się pylicy krzemowej w przemyśle produkcji blatów wyraźnie pokazało, że nawet kraje o wysokich dochodach nie są odporne na tę możliwą do zapobiegania chorobę zawodową 26.

Krajowe systemy nadzoru

Wiele krajów i regionów wdrożyło programy nadzoru nad pylicą krzemową:

  • Stany Zjednoczone: CDC’s National Institute for Occupational Safety and Health (NIOSH), departamenty zdrowia poszczególnych stanów i inne podmioty stanowe prowadzą państwowy program nadzoru nad potwierdzonymi przypadkami pylicy krzemowej 27. Pylica krzemowa została objęta ogólnokrajowym nadzorem w ramach National Public Health Surveillance System w 1999 roku i stała się chorobą podlegającą obowiązkowi zgłaszania w 2009 roku 28.
  • Michigan i Ohio prowadziły systemy nadzoru nad pylicą krzemową w latach 1988-2002, New Jersey w latach 1988-2015, a Michigan kontynuuje swój system nadzoru 29. Michigan ma wyjątkowo intensywny stanowy program nadzoru nad pylicą krzemową, który jest najdłużej działającym i jedynym kompleksowym systemem nadzoru nad pylicą krzemową w Stanach Zjednoczonych 30.
  • Kalifornia prowadzi nadzór nad pylicą krzemową, w tym aktywny nadzór nad pracownikami obróbki kamienia sztucznego 31. W grudniu 2022 roku Kalifornijski Departament Zdrowia Publicznego (CDPH) dodał zasady raportowania pylicy krzemowej do swojego systemu 32.
  • Wielka Brytania: Surveillance of Work-related and Occupational Respiratory Disease (SWORD) jest ważnym źródłem danych epidemiologicznych dotyczących pylicy krzemowej 33.
  • Polska: Prowadzony jest Centralny Rejestr Chorób Zawodowych, który gromadzi dane o przypadkach pylicy krzemowej uznanej za chorobę zawodową 34.
  • Ontario (Kanada): Prowincja Ontario ma program nadzoru nad pracownikami w przemysłach pylistych od prawie 70 lat 35.
  • Izrael: Prowadzony jest 15-letni program nadzoru nad narażeniem zawodowym na krzemionkę i związanymi z tym chorobami 36.

Metody nadzoru i monitorowania

Systemy nadzoru używają różnych metod gromadzenia danych:

  • Dane ze szpitalnych wypisów stanowią główne źródło identyfikacji przypadków. Inne źródła danych obejmują: dane demograficzne, historię zatrudnienia i informacje medyczne uzyskane z początkowych źródeł przypadków, dokumentacji medycznej i dalszego monitorowania przypadków 37.
  • Wskaźniki zdrowia zawodowego, takie jak: Wskaźnik #9: Hospitalizacje z powodu lub z pylicą oraz Wskaźnik #10: Śmiertelność z powodu lub z pylicą 38.
  • Elektroniczne raportowanie przypadków (eCR) jest wykorzystywane w niektórych stanach, takich jak Kalifornia, do identyfikacji przypadków pylicy krzemowej 39.
  • Badania przesiewowe u pracowników narażonych na krzemionkę, obejmujące kwestionariusze oddechowe, spirometrię i zdjęcia rentgenowskie klatki piersiowej. Częstotliwość nadzoru zależy w pewnym stopniu od oczekiwanej intensywności narażenia 40.

Według standardu OSHA dotyczącego krzemionki krystalicznej, pracodawcy muszą zapewnić nadzór medyczny pracownikom regularnie narażonym na pył krzemionki krystalicznej. Nadzór ten musi być przeprowadzany przez lekarza lub innego licencjonowanego pracownika ochrony zdrowia, z wyjściowym badaniem medycznym przeprowadzanym 30 dni po początkowym przydzieleniu do pracy i okresowymi badaniami co najmniej co 3 lata 41.

Wyniki programów nadzoru

Programy nadzoru nad pylicą krzemową dostarczyły ważnych informacji epidemiologicznych:

  • W badaniu prowadzonym w Ontario wskaźnik wykrywalności pylicy krzemowej wśród osób narażonych na krzemionkę, które po raz pierwszy zostały narażone na pył w 1950 roku lub później i nadal były zatrudnione w 1979 roku lub później, znacznie różnił się w zależności od czasu utajenia. Wynosił mniej niż dwa nowe przypadki na 10 000 badań w ciągu pierwszych dwóch dekad od pierwszego narażenia, osiągając dwa nowe przypadki na 1000 badań po 27 latach od pierwszego narażenia i utrzymując się na poziomie między dwoma a czterema nowymi przypadkami na 1000 badań w późniejszym okresie 42.
  • Analiza regresji Poissona wykazała, że wskaźnik pylicy krzemowej w okresie po 30 latach od pierwszego narażenia był ponad 16 razy wyższy niż wskaźnik przed upływem 20 lat od pierwszego narażenia 43.
  • W programie przesiewowym w Rwandzie, spośród 1032 górników objętych programem, u 95 (9,2%) stwierdzono radiograficzne dowody pylicy krzemowej 44.
  • W Kalifornii od października 2022 do lipca 2023 roku Kalifornijski Departament Zdrowia Publicznego otrzymał początkowe raporty o przypadkach pylicy krzemowej dotyczące 41 osób. Obróbka blatów z kamienia sztucznego była znaczącym źródłem narażenia, szczególnie wśród pracowników pochodzenia hiszpańskiego i latynoskiego 45.

Badania przesiewowe przeprowadzone w australijskim przemyśle obróbki kamienia wykazały, że w porównaniu z tomografią komputerową wysokiej rozdzielczości (HRCT), konwencjonalne zdjęcia rentgenowskie klatki piersiowej (CXR) i testy funkcji oddechowej (RFT) miały ograniczoną wartość w badaniach przesiewowych tej populacji wysokiego ryzyka 4647.

Czynniki ryzyka i grupy wysokiego ryzyka

Zrozumienie czynników ryzyka i identyfikacja grup wysokiego ryzyka jest kluczowe dla skutecznego nadzoru i zapobiegania pylicy krzemowej.

Zawody i branże wysokiego ryzyka

Nadzór medyczny pod kątem pylicy krzemowej powinien być rozważany dla pracowników w zawodach wysokiego ryzyka, w tym:

  • Budownictwo
  • Górnictwo (węglowe i niewęglowe)
  • Odlewnictwo
  • Produkcja cegieł i płytek
  • Ceramika
  • Produkcja łupków
  • Produkcja
  • Kamieniołomy
  • Obróbka kamienia 4849

W ostatnich latach szczególną uwagę zwrócono na pracowników zajmujących się obróbką kamienia sztucznego (kwarcowego) do produkcji blatów kuchennych. Ryzyko pylicy krzemowej związane z produkcją kamienia sztucznego zostało po raz pierwszy zidentyfikowane w 2012 roku, po wybuchu ciężkiej pylicy krzemowej wśród izraelskich pracowników, którzy cięli na sucho produkty z kamienia sztucznego 50.

Badania w Chinach wykazały, że górnicy w kopalniach niemetali, metali nieżelaznych, małych i odkrywkowych mają wyższe ryzyko pylicy krzemowej ze względu na wyższy poziom narażenia na pył krzemionki 5152.

Determinanty ryzyka pylicy krzemowej

Kilka czynników wpływa na ryzyko rozwoju pylicy krzemowej:

  • Czas ekspozycji: Ryzyko wzrasta wraz z liczbą lat narażenia. Wśród pracowników zatrudnionych przez ponad 30 lat, 12% rozwinęło pylicę krzemową 53.
  • Intensywność narażenia: Badanie górników złota z Afryki Południowej wykazało 25% skumulowane ryzyko pylicy krzemowej po 28 latach górnictwa przy ekspozycji na krzemionkę na poziomie 0,33 mg/m³ 54.
  • Skumulowana ekspozycja: Badanie kamieniarzy z Hong Kongu wykazało, że skumulowana ekspozycja na krzemionkę między 1 a 5 mg/m³ rocznie prowadziła do radiologicznej pylicy krzemowej u 32% mężczyzn w wieku 50 lat i starszych 55.
  • Palenie tytoniu: Wskaźnik pylicy krzemowej był wyższy wśród palaczy niż wśród osób, które nigdy nie paliły (współczynnik częstości 1,54) 56.
  • Metody obróbki: Sucha obróbka kamienia sztucznego jest wysoce niebezpieczną praktyką, która została powiązana z pylicą krzemową w wielu krajach 57.

Pylica krzemowa a gruźlica – współwystępowanie

Związek między pylicą krzemową a gruźlicą jest dobrze udokumentowany i badany od początku XX wieku 5859.

Epidemiologia współwystępowania

Ryzyko rozwoju gruźlicy płuc u pacjentów z pylicą krzemową jest 2,8 do 39 razy wyższe niż u zdrowych osób z grupy kontrolnej, w zależności od ciężkości pylicy krzemowej 6061. Ryzyko rozwoju gruźlicy pozapłucnej jest również do 3,7 razy wyższe niż u zdrowych osób z grupy kontrolnej 62.

W Brazylii odnotowano 52% występowanie gruźlicy płuc w postaci masywnego włóknienia postępującego u pacjentów z pylicą krzemową 6364. W prospektywnym badaniu oceniającym 1153 górników złota, roczna zapadalność na gruźlicę wynosiła 2,7% u osób z pylicą krzemową, w porównaniu z 0,98% u osób bez pylicy krzemowej 6566.

Badania wykazały, że ryzyko rozwoju gruźlicy płuc jest proporcjonalne do ciężkości pylicy krzemowej i intensywności narażenia 6768. Zapadalność była proporcjonalna do ciężkości pylicy krzemowej, osiągając do 6,3% u pacjentów, których zdjęcia rentgenowskie klatki piersiowej wykazywały intensywne zagęszczenie guzków 69.

Nadzór i profilaktyka gruźlicy u pacjentów z pylicą krzemową

Z uwagi na wysokie ryzyko współwystępowania, eksperci zalecają współpracę między programami kontroli gruźlicy i pylicy krzemowej 7071. II Brazylijski Konsensus w sprawie Gruźlicy zaleca, aby pacjenci z pylicą krzemową i silnie dodatnimi wynikami próby tuberkulinowej (nacieki ≥10 mm) otrzymywali izoniazyd w dawce 300 mg/dziennie (lub 10 mg/kg/dziennie) przez sześć miesięcy 7273.

Eksperci uważają, że pacjenci z pylicą krzemową, a także osoby z okresami narażenia na krzemionkę dłuższymi niż 10 lat, nawet bez choroby, powinni być poddawani próbom tuberkulinowym w początkowej ocenie, ponieważ uznaje się, że ta populacja jest narażona na zwiększone ryzyko gruźlicy 7475.

Badanie porównawcze wykazało, że pacjenci z krzemico-gruźlicą mieli 2,3 (95% CI 1,6-3,4) razy wyższe szanse niekorzystnych wyników leczenia w porównaniu z pacjentami z gruźlicą bez pylicy krzemowej 76. Wszyscy pacjenci z pylicą krzemową powinni być badani pod kątem gruźlicy i leczeni zgodnie z wytycznymi krajowego programu gruźlicy 77.

Wyzwania i ograniczenia nadzoru

Pomimo znaczenia nadzoru nad pylicą krzemową, istnieje wiele wyzwań i ograniczeń w skutecznym monitorowaniu tej choroby.

Problemy z raportowaniem i diagnozą

Dokładna ocena częstości występowania pylicy krzemowej i innych pylic płuc w Stanach Zjednoczonych i w innych krajach jest trudna z wielu powodów. Liczba osób narażonych na ryzyko pylicy krzemowej i dotkniętych chorobą jest nieznana z powodu złych praktyk prowadzenia dokumentacji, opóźnień czasowych od narażenia do diagnozy oraz słabego zrozumienia związku między narażeniem a chorobą 78.

System raportowania urazów i chorób zawodowych w Stanach Zjednoczonych nie rejestruje wielu przypadków, co prowadzi do słabego zrozumienia zapadalności i chorobowości pylicy krzemowej 79. Zidentyfikowane liczby przypadków są znacznym niedoszacowaniem z powodu niedociągnięć w systemach raportowania i programach nadzoru nad zawodowym zdrowiem oddechowym w wielu krajach 80.

Wyzwaniem jest również diagnostyka pylicy krzemowej, zwłaszcza we wczesnych stadiach. Badania wykazały, że konwencjonalne zdjęcia rentgenowskie klatki piersiowej (CXR) mają ograniczoną wartość w wykrywaniu wczesnych stadiów pylicy krzemowej 8182.

Potrzeba lepszych systemów nadzoru

Eksperci podkreślają potrzebę lepszych systemów nadzoru nad pylicą krzemową:

  • Konieczne jest aktualizowanie szacunków i analizowanie obciążenia pylicą krzemową według wieku, czasu i lokalizacji 83.
  • Departamenty zdrowia i decydenci powinni zwracać większą uwagę na wdrażanie taktyk zapobiegawczych i poprawę jakości życia obecnych pacjentów 84.
  • Elektroniczne raportowanie przypadków (eCR) może pomóc w wyjaśnieniu zakresu i rozległości tego ważnego stanu zdrowia publicznego wśród wrażliwych pracowników, z celem opracowania i wdrożenia skutecznych strategii zapobiegawczych 85.
  • Ważne jest, aby pracownicy służby zdrowia rutynowo pytali pacjentów o ich pracę jako ważny determinant zdrowia 86.

W Polsce zaleca się rozważenie opracowania nowych wytycznych diagnostycznych z wykorzystaniem innych badań obrazowych, takich jak tomografia komputerowa wysokiej rozdzielczości, oraz poprawę standardów monitorowania medycznego narażonych pracowników 87.

Trendy i perspektywy na przyszłość

Mimo ogólnego spadku standaryzowanych wiekowo wskaźników pylicy krzemowej, absolutna liczba przypadków wzrasta, co wskazuje na potrzebę ciągłych wysiłków w zakresie nadzoru i zapobiegania.

Prognozowane trendy

Analiza danych GBD 2019 wskazuje, że trend standaryzowanych wiekowo wskaźników (ASR) wykazał gwałtowny spadek w latach 2005-2019, po którym nastąpił ciągły spadek aż do 2029 roku 8889. Najwyższe obciążenie pylicą krzemową zostało przeniesione głównie na osoby starsze w latach 1990-2019 9091.

Liczba przypadków zachorowań, chorobowości i DALY osiągnęła szczyt po 50. roku życia w 2019 roku, co może być związane ze starzeniem się globalnej populacji 92. Generalnie obciążenie chorobą pylicy krzemowej wykazuje tendencję spadkową, ale nie można go ignorować 93.

Rekomendacje dla przyszłych działań

Aby skutecznie zwalczać pylicę krzemową, zaleca się następujące działania:

  • Wdrożenie zalecanych środków ochrony przed ekspozycją na krzemionkę, w tym unikanie cięcia na sucho, wykorzystanie kontroli inżynieryjnych w celu zmniejszenia uwalniania pyłu i poprawy wentylacji oraz zapewnienie odpowiedniego sprzętu ochrony osobistej w sytuacjach, gdy nie można uniknąć cięcia na sucho 94.
  • Poprawa nadzoru medycznego nad narażonymi pracownikami, w tym badań przesiewowych w kierunku pylicy krzemowej i gruźlicy 95.
  • Integracja nadzoru nad pylicą krzemową z rutynnowymi badaniami przesiewowymi w kierunku chorób niezakaźnych 96.
  • Rozwój kompleksowego nadzoru nad zawodowymi chorobami płuc, w tym pylicą krzemową, w krajach o niskich i średnich dochodach 97.
  • Wdrożenie współpracy między programami kontroli gruźlicy i pylicy krzemowej, szczególnie w obszarach o wysokim obciążeniu pylicą krzemową 9899.

Dokładna historia zawodowa powinna stanowić część każdej diagnostycznej oceny śródmiąższowej choroby płuc 100. Ponadto, wszyscy pacjenci z gruźlicą, którzy mają historię zawodowego narażenia na pył, powinni być badani pod kątem pylicy krzemowej i objęci odpowiednią rehabilitacją pulmonologiczną/zawodową 101.

  • #1 Global incidence, prevalence and disease burden of silicosis: 30 years’ overview and forecasted trends
    https://pmc.ncbi.nlm.nih.gov/articles/PMC10353232/
    Globally, silicosis accounts for 90% of all pneumoconiosis cases and is a serious public health issue. A comprehensive analysis at temporal, spatial and population levels with the most updated data from GBD 2019 is provided in this study to estimate the disease burden of silicosis from 1990 to 2019 and make predictions to 2029. We delineated silicosis data on incidence, prevalence, and disability-adjusted life years (DALYs) as well as age-standardized rates (ASRs) across 30 years from GBD 2019. Globally, silicosis incident, prevalent cases, and DALYs increased by 64.6%, 91.4%, and 20.8%, respectively. However, all the corresponding ASRs showed overall downward trends with an estimated average APC (AAPC) of -0.5(-0.7 to -0.3), -0.2(-0.5 to 0.0), and 2.0(-2.2 to -1.8), respectively. The highest disease burden of silicosis was mainly transferred to the older from 1990 to 2019. The trend of ASRs demonstrated a rapid decline between 2005 and 2019, followed by a continuous decline until 2029. Though disease burden of silicosis has been on a decline in general from 1990 to 2019, which shows a promising prospect but cannot be ignored. Updating estimates and deconstructing the burden of silicosis by age, time, and location is of paramount importance but has been overlooked. The Global Burden of Diseases Study (GBD) 2019 covered 369 types of diseases and injuries across 204 countries and territories, which can help promote the decoding of landscape and dynamics underlying silicosis from a unique perspective. In the global analysis of 204 countries and different regions, we assessed the trends in numbers and ASRs of silicosis between 1990 and 2019. The age-standardized incidence rate (ASIR) was found to have decreased by an average of 0.5% per year in the same period. The age-standardized prevalence rate (ASPR) declined from 33.13/100,000 in 1990 to 31.60/100,000 in 2019 by an average of 0.2% each year. The age-standardized DALY rate (ASDR) was reduced from 13.88/100,000 in 1990 to 7.87/100,000 in 2019 with an AAPC of 2.0%. The highest silicosis burden occurred in regions with middle SDI and high-middle SDI, followed by low-middle SDI and high SDI, while the lowest was found in low SDI. The BOD of silicosis was mainly borne by countries with middle SDI and high-middle SDI. Silicosis continues to be one of the most important occupational health issues and causes a potentially serious BOD worldwide. Though ASRs have experienced some fluctuations from 1990 to 2019, the trends may still be expected to descend steadily in the future.

    https://www.nj.gov/health/workplacehealthandsafety/occupational-health-surveillance/silicosis/
    Silicosis Surveillance and Intervention […] Silicosis is a disabling and sometimes fatal lung disease caused by overexposure to dust containing crystalline silica. Silicosis cannot be cured, but it can be prevented. […] Breathing dust generated from working with these materials can scar the lungs. Once silicosis develops, the damage is permanent. The scarring of the lung tissue cannot be reversed. […] Symptoms and Types of Silicosis […] Silicosis begins with few, if any, symptoms. Once present, these symptoms can include shortness of breath, severe cough, wheezing, and chest tightness. Breathing dust containing crystalline silica has also been linked to other diseases such as tuberculosis, kidney disease, and lung cancer. Symptoms can include fever, weight loss, and night sweats. These symptoms can become worse over time, leading to death.
  • #4 Current global perspectives on silicosis—Convergence of old and newly emergent hazards
    https://pmc.ncbi.nlm.nih.gov/articles/PMC9310854/
    Silicosis not a disease of the past. It is an irreversible, fibrotic lung disease specifically caused by exposure to respirable crystalline silica (RCS) dust. Over 20,000 incident cases of silicosis were identified in 2017 and millions of workers continue to be exposed to RCS. Identified case numbers are however a substantial underestimation due to deficiencies in reporting systems and occupational respiratory health surveillance programmes in many countries. […] This review provides global and regional perspectives of the epidemiology of silicosis, sources of exposure and barriers that have hampered global elimination. […] In 2017, the Global Burden of Disease (GBD) study identified 23,695 incident cases of silicosis (age-standardized incidence rate [ASIR] = 0.30 per 100,000), which represents 39% of the 60,055 incident cases of pneumoconiosis.

Globally, silicosis incident, prevalent cases, and DALYs increased by 64.6%, 91.4%, and 20.8%, respectively. However, all the corresponding ASRs showed overall downward trends with an estimated average APC (AAPC) of -0.5(-0.7 to -0.3), -0.2(-0.5 to 0.0), and 2.0(-2.2 to -1.8), respectively. The highest disease burden of silicosis was mainly transferred to the older from 1990 to 2019. The trend of ASRs demonstrated a rapid decline between 2005 and 2019, followed by a continuous decline until 2029. Though disease burden of silicosis has been on a decline in general from 1990 to 2019, which shows a promising prospect but cannot be ignored. Updating estimates and deconstructing the burden of silicosis by age, time, and location is of paramount importance but has been overlooked. The Global Burden of Diseases Study (GBD) 2019 covered 369 types of diseases and injuries across 204 countries and territories, which can help promote the decoding of landscape and dynamics underlying silicosis from a unique perspective. In the global analysis of 204 countries and different regions, we assessed the trends in numbers and ASRs of silicosis between 1990 and 2019. The age-standardized incidence rate (ASIR) was found to have decreased by an average of 0.5% per year in the same period. The age-standardized prevalence rate (ASPR) declined from 33.13/100,000 in 1990 to 31.60/100,000 in 2019 by an average of 0.2% each year. The age-standardized DALY rate (ASDR) was reduced from 13.88/100,000 in 1990 to 7.87/100,000 in 2019 with an AAPC of 2.0%. The highest silicosis burden occurred in regions with middle SDI and high-middle SDI, followed by low-middle SDI and high SDI, while the lowest was found in low SDI. The BOD of silicosis was mainly borne by countries with middle SDI and high-middle SDI. Silicosis continues to be one of the most important occupational health issues and causes a potentially serious BOD worldwide. Though ASRs have experienced some fluctuations from 1990 to 2019, the trends may still be expected to descend steadily in the future.

    Silicosis not a disease of the past. It is an irreversible, fibrotic lung disease specifically caused by exposure to respirable crystalline silica (RCS) dust. Over 20,000 incident cases of silicosis were identified in 2017 and millions of workers continue to be exposed to RCS. Identified case numbers are however a substantial underestimation due to deficiencies in reporting systems and occupational respiratory health surveillance programmes in many countries. […] This review provides global and regional perspectives of the epidemiology of silicosis, sources of exposure and barriers that have hampered global elimination. […] In 2017, the Global Burden of Disease (GBD) study identified 23,695 incident cases of silicosis (age-standardized incidence rate [ASIR] = 0.30 per 100,000), which represents 39% of the 60,055 incident cases of pneumoconiosis.

[…] In the wake of modern-day silicosis cases, researchers have called for larger studies to better understand the disease and the discovery of effective treatments. […] This study examines the use of electronic case reporting to identify silicosis cases in California. […] From October 2022 to July 2023, the California Department of Public Health received initial silicosis case reports for 41 individuals. […] Notably, engineered stone countertop fabrication was a significant source of exposure, especially among Hispanic and Latino workers. […] It is important that health care providers routinely ask patients about their work as an important determinant of health, the authors write. Being aware of the risks associated with work exposures, as well as the regulations, medical monitoring, and prevention strategies that address those risks can help guide patient care.

    US data show a lessening of the rate of decline in deaths from silicosis after 1995, with an increased proportion of deaths in the age group younger than 45 years. These data indicate that intense overexposures to respirable crystalline silica continue to occur despite the existence of legally enforceable limits. A study of South African gold miners after they had left the mining industry documented a 25% cumulative risk of silicosis after 28 years of mining at a 0.33 mg/m3 silica exposure level. A death certificate study of South Dakota gold miners predicted that a 45-year cumulative exposure from ages 20 to 65 years at 0.09 mg/m3 would result in a 47% lifetime risk of silicosis. A study of Hong Kong granite quarriers indicated that cumulative silica exposure between 1 and 5 mg/m3 per year led to radiologic silicosis in 32% of men aged 50 years and older. In a study of Colorado miners who had left the hard rock mining industry, estimated exposures using silica measurements (in contrast to dust measurements) were associated with even higher risks of radiologic silicosis. In China, 23 million workers are exposed to silica, whereas in the United States, the National Institute for Occupational Safety and Health (NIOSH) has estimated that at least 1.7 million workers are exposed to silica, with between 1500 and 2360 of whom will develop silicosis each year.

China, for instance, estimates more than 24,000 events of death every year due to silicosis (2). […] In light of the important impact of silicosis, the epidemiologic analysis by Barber et al. found the Surveillance of work-related and occupational respiratory disease (SWORD) to be an important resource of epidemiological data on Silicosis to the literature. […] The study by Barber et al. was the first attempt to deeply understand the demographic risk factors and distribution of silicosis across different age groups in the UK. […] In conclusion, the demographic results pointed in SWORD may be used as a baseline for future investigations to explore the outcomes of recent efforts to reduce workers exposure to silica. Moreover, there is an impending need for more demographic studies evaluating silicosis in other developed and developing countries to better understand the epidemiology of this disease worldwide.

Silicoses accounted for 12.8-21.2% of all pneumoconioses. […] The number of confirmed cases of silicosis in Poland decreased in 2000-2019 but the disease still remains an important health problem. Prevention is crucial to reduce further disease incidence. The medical monitoring standards of exposed workers should be improved. Developing new diagnosing guidelines with the use of other imaging examinations, like high-resolution computed tomography, has to be considered.

    Occupational Silica Exposure and Dose–Response for Related Disorders—Silicosis, Pulmonary TB, AIDs and Renal Diseases: Results of a 15-Year Israeli Surveillance […] Background: The exposure patterns of respirable crystalline silica based on environmental records, as well as the link to different diseases, are not well described. Aims and objectives: In this study, we evaluated the risk for various diseases in relation to occupational silica exposure, including Silicosis, pulmonary tuberculosis (TB), Autoimmune disorders (AIDs) and Renal diseases. […] We found 25 (9.58%) incident cases of silicosis, 10 cases of chronic obstructive pulmonary disease (COPD) and emphysema (3.83%), six cases of several AIDs (2.30%), five cases of pulmonary TB (1.92%), three cases of renal diseases (1.15%), two cases of sarcoidosis (0.77%) and no lung cancer cases. […] Silica exposure was a significant risk factor for silicosis, pulmonary TB and AIDs. Our findings are important given persistent worldwide silica-related epidemics in low and high-income countries. […] The worldwide incidence of silicosis is increasing due to the high demand for occupations that involve silica exposure and the lack of proper protection. […] The threshold limit value (TLV) for RCS in Israel is 0.1 mg/m³. According to the Israeli regulations, silica workers are required to undergo biennial medical surveillance that includes a medical examination, pulmonary function tests and a chest X-ray every five years. […] Although there is some evidence of an association between silica exposure and the incidence of various disorders, the absence of reliable silica quantitative dosimetric data, the relative rarity of these outcomes and the fact that most evidence reported has been statistically non-significant, calls for further research, which is especially crucial given the persistent worldwide silica-related epidemics in both low and high-income countries. […] The contribution of silica exposure to the risk of pulmonary TB has been examined in multiple studies and varies according to the studied population and the general prevalence of pulmonary TB in the studied area. […] Our findings support the association described in the literature between silica exposure and pulmonary TB. […] Our study indicates an association between silica exposure and AIDs.

    Accurate assessment of the frequency of silicosis and other pneumoconioses in the United States and in other countries is challenging for many reasons. The number of people who are at risk of silicosis and who are affected by the disease is unknown because of poor record-keeping practices, time delays from exposure to diagnosis, and poor understanding of the relationship between exposure and disease. Over 2 million workers have experienced an occupational exposure to silica, with male workers predominantly affected, reflecting the occupations at risk. […] Several epidemics of silicosis have been reported from a number of nations, including the United States. The worst epidemic of silicosis occurred in 1930-1931, during the construction of the Gauley Bridge tunnel in West Virginia; more than 400 of the estimated 2000 men who drilled rocks died of silicosis, and almost all the survivors developed silicosis. More recently, in 1996, silicosis was reported in 60 of 1072 workers in an automotive factory. The risk of developing the disease increased as the number of years of exposure increased. Among workers who were employed for more than 30 years, 12% developed silicosis.

These data indicate that intense overexposures to respirable crystalline silica continue to occur despite the existence of legally enforceable limits. A study of South African gold miners after they had left the mining industry documented a 25% cumulative risk of silicosis after 28 years of mining at a 0.33 mg/m3 silica exposure level. A death certificate study of South Dakota gold miners predicted that a 45-year cumulative exposure from ages 20 to 65 years at 0.09 mg/m3 would result in a 47% lifetime risk of silicosis. A study of Hong Kong granite quarriers indicated that cumulative silica exposure between 1 and 5 mg/m3 per year led to radiologic silicosis in 32% of men aged 50 years and older. In a study of Colorado miners who had left the hard rock mining industry, estimated exposures using silica measurements (in contrast to dust measurements) were associated with even higher risks of radiologic silicosis. In China, 23 million workers are exposed to silica, whereas in the United States, the National Institute for Occupational Safety and Health (NIOSH) has estimated that at least 1.7 million workers are exposed to silica, with between 1500 and 2360 of whom will develop silicosis each year.

    https://emedicine.medscape.com/article/302027-overview
    Accurate assessment of the frequency of silicosis and other pneumoconioses in the United States and in other countries is challenging for many reasons. The number of people who are at risk of silicosis and who are affected by the disease is unknown because of poor record-keeping practices, time delays from exposure to diagnosis, and poor understanding of the relationship between exposure and disease. Over 2 million workers have experienced an occupational exposure to silica, with male workers predominantly affected, reflecting the occupations at risk. […] Several epidemics of silicosis have been reported from a number of nations, including the United States. The worst epidemic of silicosis occurred in 1930-1931, during the construction of the Gauley Bridge tunnel in West Virginia; more than 400 of the estimated 2000 men who drilled rocks died of silicosis, and almost all the survivors developed silicosis. More recently, in 1996, silicosis was reported in 60 of 1072 workers in an automotive factory. The risk of developing the disease increased as the number of years of exposure increased. Among workers who were employed for more than 30 years, 12% developed silicosis.
  • #79 What is silicosis and what does research say about it?
    https://journalistsresource.org/home/silicosis-an-explainer-and-research-roundup/
    Silicosis is a progressive, debilitating and sometimes fatal lung disease caused by breathing silica dust from cutting, drilling, chipping or grinding materials such as granite, sandstone, slate or artificial stone. The disease mostly affects workers in construction, stone countertop fabrication, mining, and even those who sandblast and stonewash denim jeans to create a worn out look. […] In the U.S. about 2.3 million workers are exposed to silica dust on the job, according to the American Lung Association. Other estimates show approximately 10 million workers in India, 3.2 million in the European Union and 2 million in Brazil work with material containing silica. […] However, the reporting system for occupational injuries and illnesses in the United States fails to capture many cases, leading to a poor understanding of silicosis incidence and prevalence, writes Ryan F. Hoy, who has published extensively on the topic, in a June 2022 article in Respirology.
  • #80 Current global perspectives on silicosis—Convergence of old and newly emergent hazards
    https://pmc.ncbi.nlm.nih.gov/articles/PMC9310854/
    Silicosis not a disease of the past. It is an irreversible, fibrotic lung disease specifically caused by exposure to respirable crystalline silica (RCS) dust. Over 20,000 incident cases of silicosis were identified in 2017 and millions of workers continue to be exposed to RCS. Identified case numbers are however a substantial underestimation due to deficiencies in reporting systems and occupational respiratory health surveillance programmes in many countries. […] This review provides global and regional perspectives of the epidemiology of silicosis, sources of exposure and barriers that have hampered global elimination. […] In 2017, the Global Burden of Disease (GBD) study identified 23,695 incident cases of silicosis (age-standardized incidence rate [ASIR] = 0.30 per 100,000), which represents 39% of the 60,055 incident cases of pneumoconiosis.

Compared with HRCT chest, CXR and RFTs had limited value in screening this high-risk population. […] The prevalence of silicosis among SBI workers had not been previously quantified. […] There is also concern that respiratory function tests (RFT) and chest X-rays (CXR) used for surveillance of silica-exposed workers have poor sensitivity to detect early stage silicosis in this industry. […] This study confirmed a very high risk of silicosis associated with work in the SBI. […] This prevalence estimate is similar to that found in another screening programme undertaken in Queensland, Australia.

A comprehensive analysis at temporal, spatial and population levels with the most updated data from GBD 2019 is provided in this study to estimate the disease burden of silicosis from 1990 to 2019 and make predictions to 2029. We delineated silicosis data on incidence, prevalence, and disability-adjusted life years (DALYs) as well as age-standardized rates (ASRs) across 30 years from GBD 2019. Globally, silicosis incident, prevalent cases, and DALYs increased by 64.6%, 91.4%, and 20.8%, respectively. However, all the corresponding ASRs showed overall downward trends with an estimated average APC (AAPC) of -0.5(-0.7 to -0.3), -0.2(-0.5 to 0.0), and 2.0(-2.2 to -1.8), respectively. The highest disease burden of silicosis was mainly transferred to the older from 1990 to 2019. The trend of ASRs demonstrated a rapid decline between 2005 and 2019, followed by a continuous decline until 2029. Though disease burden of silicosis has been on a decline in general from 1990 to 2019, which shows a promising prospect but cannot be ignored. Updating estimates and deconstructing the burden of silicosis by age, time, and location is of paramount importance but has been overlooked. The Global Burden of Diseases Study (GBD) 2019 covered 369 types of diseases and injuries across 204 countries and territories, which can help promote the decoding of landscape and dynamics underlying silicosis from a unique perspective. In the global analysis of 204 countries and different regions, we assessed the trends in numbers and ASRs of silicosis between 1990 and 2019. The age-standardized incidence rate (ASIR) was found to have decreased by an average of 0.5% per year in the same period. The age-standardized prevalence rate (ASPR) declined from 33.13/100,000 in 1990 to 31.60/100,000 in 2019 by an average of 0.2% each year. The age-standardized DALY rate (ASDR) was reduced from 13.88/100,000 in 1990 to 7.87/100,000 in 2019 with an AAPC of 2.0%. The highest silicosis burden occurred in regions with middle SDI and high-middle SDI, followed by low-middle SDI and high SDI, while the lowest was found in low SDI. The BOD of silicosis was mainly borne by countries with middle SDI and high-middle SDI. Silicosis continues to be one of the most important occupational health issues and causes a potentially serious BOD worldwide. Though ASRs have experienced some fluctuations from 1990 to 2019, the trends may still be expected to descend steadily in the future.

    Given this, it is likely that many patients with silicosis related to engineered stone fabrication remain unrecognized. […] Silicosis is preventable. Through avoidance of dry cutting, utilizing engineering controls to reduce dust release and improve ventilation and providing appropriate personal protective equipment in situations where dry cutting cannot be avoided, the amount of RCS a worker is exposed to can be significantly reduced. […] A thorough occupational history should form part of any diagnostic evaluation for interstitial lung disease.

    Our case-finding activities identified 95 mine workers with radiographic evidence of silicosis, corresponding to a prevalence of 9.2% in our sample. […] We conclude that conducting large-scale occupational lung disease case-finding is clinically and economically feasible in resource-limited settings and can be effectively integrated with routine noncommunicable disease case-finding. […] Our case-finding program highlights the importance of ongoing stakeholder partnership, in our case, particularly between PIH/IMB, WMP, and the MOH. […] We stress the importance of including TB case-finding in occupational lung disease surveillance, given the overlap of clinical symptoms and radiographic findings and the high rates of co-occurrence.

    All patients with TB who have a history of occupational dust exposure should be evaluated for silicosis and provided appropriate pulmonary/vocational rehabilitation. […] The need of integrating silicosis control efforts with TB control programs has been widely emphasized. […] However, the implementation mechanisms of such an integrated TB-silicosis program are unexplored. […] The lack of a cure for silicosis, diagnostic challenges in distinguishing the two diseases even on radiography, and facilitating early detection of cases called for the need for collaborative TB-silicosis activities. […] The experts also perceived that bidirectional collaborative activities between silicosis and TB would help in improving treatment outcomes of anti-TB regimen through early diagnosis and prompt management.

[…] The experts also felt that while TB surveillance was well-established, silicosis surveillance was inadequate in India. […] Early detection of silicosis and TB among silica-exposed workers has been recommended to prevent further lung damage and limit the spread of TB in the community. […] Controlling/eliminating silica dust exposure would significantly lower the burden of silicosis and TB. […] A national silicosis elimination program at the block level must be devised through multi-sector engagement, and its implementation must be monitored by the government. […] Collaborative TB-silicosis activities should be undertaken in India to achieve significant progress in the prevention and control of silico-tuberculosis.
