Pylica krzemowa
Objawy

Pylica krzemowa (silicosis) to przewlekła, postępująca i nieodwracalna choroba płuc wywołana inhalacją pyłu krzemionkowego, prowadząca do zapalenia i zwłóknienia tkanki płucnej, co skutkuje utratą funkcji oddechowej i niewydolnością oddechową. Wyróżnia się trzy typy choroby: ostrą (rozwijającą się w ciągu kilku tygodni do lat po intensywnej ekspozycji, z ciężką niewydolnością oddechową i śmiertelnością w ciągu 1-2 lat), przyspieszoną (po 3-10 latach ekspozycji, z szybszym przebiegiem niż postać przewlekła) oraz przewlekłą (najczęstsza, rozwijająca się po 10-30 latach narażenia na niższe stężenia pyłu). Objawy obejmują kaszel, duszność wysiłkową, zmęczenie, a w zaawansowanych stadiach także sinicę, utratę masy ciała i niewydolność oddechową. Progresywne masywne zwłóknienie (PMF) występuje u 18-37% pacjentów, prowadząc do znacznego upośledzenia funkcji płuc i złego rokowania.

Pylica krzemowa – wprowadzenie do choroby

Pylica krzemowa (silicosis) to poważna, przewlekła, postępująca i nieodwracalna choroba płuc spowodowana wdychaniem drobin krzemionki (dwutlenku krzemu). Gdy cząsteczki krzemionki przedostają się do płuc, powodują zapalenie, a następnie bliznowacenie (zwłóknienie) tkanki płucnej, co prowadzi do utraty funkcji płuc i postępującej niewydolności oddechowej. Pylica krzemowa jest chorobą zawodową, najczęściej występującą u osób pracujących w branżach takich jak górnictwo, obróbka kamienia, budownictwo czy produkcja szkła i ceramiki.123

Charakterystycznym elementem pylicy krzemowej jest to, że choroba może postępować nawet po zakończeniu narażenia na pył krzemionkowy, ponieważ cząsteczki pozostają w płucach i nadal powodują uszkodzenia. Niestety, obecnie nie istnieje skuteczne leczenie, które mogłoby odwrócić proces zwłóknienia płuc w pylicy krzemowej – jest to choroba nieuleczalna.123

Rodzaje pylicy krzemowej

Wyróżnia się trzy główne typy pylicy krzemowej, które różnią się czasem ekspozycji, intensywnością narażenia, szybkością rozwoju oraz nasileniem objawów:123

Pylica krzemowa ostra

Ostra pylica krzemowa rozwija się po intensywnym narażeniu na bardzo wysokie stężenia pyłu krzemionkowego w krótkim czasie – od kilku tygodni do kilku lat. Jest najrzadszą, ale jednocześnie najcięższą formą choroby. Objawy pojawiają się szybko i są bardzo nasilone, prowadząc do ciężkiej niewydolności oddechowej, a nawet śmierci w ciągu kilku miesięcy do 2 lat.123

Pylica krzemowa przyspieszona

Przyspieszona pylica krzemowa występuje po 3-10 latach narażenia na wysokie stężenia krzemionki. Jest to forma choroby o szybszym przebiegu niż postać przewlekła, gdzie objawy i zmiany w płucach postępują w przyspieszonym tempie. Typowo rozwija się po około 5-10 latach od pierwszej ekspozycji.123

Pylica krzemowa przewlekła

Przewlekła pylica krzemowa to najczęstsza postać choroby, rozwijająca się po długotrwałym (10-30 lat) narażeniu na niższe stężenia pyłu krzemionkowego. Początkowo może przebiegać bezobjawowo lub powodować łagodne objawy, które stopniowo nasilają się w miarę postępu choroby. Objawy mogą pojawić się dopiero po wielu latach, nawet po zakończeniu narażenia zawodowego.123

Objawy pylicy krzemowej

Objawy pylicy krzemowej mogą różnić się w zależności od typu choroby, czasu trwania i intensywności ekspozycji na krzemionkę, a także od indywidualnych czynników zdrowotnych pacjenta.12

Wczesne objawy

We wczesnym stadium pylicy krzemowej objawy mogą być nieobecne lub bardzo subtelne. Wiele osób nie zdaje sobie sprawy z rozwijającej się choroby, ponieważ zmiany w płucach postępują bezobjawowo. Pierwsze symptomy, które mogą się pojawić, to:123

  • Uporczywy, suchy kaszel12
  • Duszność wysiłkowa (początkowo pojawiająca się tylko podczas wysiłku fizycznego)12
  • Zmęczenie i osłabienie12
  • Uczucie ucisku w klatce piersiowej12

Objawy zaawansowane

W miarę postępu choroby objawy stają się bardziej nasilone i mogą obejmować:123

  • Nasilający się kaszel, często produktywny (z wydzieliną lub plwociną)12
  • Postępująca duszność (trudności w oddychaniu), również w spoczynku12
  • Nasilone zmęczenie i osłabienie12
  • Niezamierzona utrata masy ciała12
  • Ból w klatce piersiowej12
  • Poty nocne12
  • Epizody gorączki12
  • Obrzęk nóg12
  • Sine zabarwienie skóry (sinica), szczególnie widoczne na wargach i paznokciach12

Objawy specyficzne dla poszczególnych typów pylicy krzemowej

Każdy z typów pylicy krzemowej charakteryzuje się specyficznym zestawem objawów:12

  • Ostra pylica krzemowa: gorączka, ostry ból w klatce piersiowej, intensywna duszność, szybka utrata wagi, znaczne osłabienie, niewydolność oddechowa rozwijająca się w ciągu miesięcy od początkowej ekspozycji123
  • Przyspieszona pylica krzemowa: postępująca duszność, produktywny kaszel, objawy podobne do przewlekłego zapalenia oskrzeli, szybsze pogarszanie się funkcji płuc123
  • Przewlekła pylica krzemowa: stopniowo nasilające się trudności w oddychaniu, początkowo podczas wysiłku, z czasem również w spoczynku, przewlekły kaszel, zmęczenie, u niektórych pacjentów choroba może postępować do stadium rozległego zwłóknienia (ang. progressive massive fibrosis, PMF)123

Progresja pylicy krzemowej

Pylica krzemowa to choroba postępująca, co oznacza, że z czasem stan płuc pogarsza się, nawet jeśli ekspozycja na pył krzemionki ustała. Tempo progresji zależy od wielu czynników, w tym intensywności i czasu trwania ekspozycji, wieku pacjenta oraz współistniejących chorób.123

Naturalna progresja choroby

Naturalna progresja pylicy krzemowej zazwyczaj przebiega następująco:123

  • Początkowo, po wdychaniu cząstek krzemionki, dochodzi do rozwoju stanu zapalnego w płucach12
  • Z czasem stan zapalny prowadzi do tworzenia się guzków (zwłóknień) w tkance płucnej, szczególnie w górnych płatach płuc12
  • Stopniowo zmniejsza się pojemność płuc, co objawia się postępującą dusznością i trudnościami w oddychaniu12
  • W zaawansowanych przypadkach może rozwinąć się rozległe zwłóknienie (PMF), które znacząco upośledza funkcję płuc12

Progresywne masywne zwłóknienie (PMF)

Progresywne masywne zwłóknienie (PMF) to najbardziej zaawansowana postać pylicy krzemowej, charakteryzująca się obecnością rozległych mas zwłókniałej tkanki w płucach. PMF rozwija się u około 18-37% osób z pylicą krzemową, zwykle po około 5 latach od pierwszej ekspozycji na krzemionkę.123

Pacjenci z PMF doświadczają poważnych objawów oddechowych:12

  • Znaczna duszność, również w spoczynku12
  • Przewlekły, nasilony kaszel12
  • Utrata masy ciała12
  • Sinica12
  • Poważne upośledzenie funkcji oddechowej12

PMF prowadzi do rozległego zniszczenia tkanki płucnej, co skutkuje zmniejszoną zdolnością perfuzji, upośledzeniem funkcji płuc i podwyższonym oporem płucnym. Rokowanie jest niekorzystne, z postępującym pogorszeniem funkcji płuc, często prowadzącym do niewydolności oddechowej i serca płucnego (cor pulmonale).123

Czynniki wpływające na progresję choroby

Na tempo progresji pylicy krzemowej wpływa wiele czynników:12

  • Intensywność i czas ekspozycji – wyższe stężenia pyłu krzemionkowego i dłuższy czas narażenia przyspieszają rozwój choroby12
  • Rodzaj krzemionki – narażenie na sztuczny kamień (zawierający wyższe stężenie krzemionki) powoduje szybszy rozwój choroby niż ekspozycja na naturalne źródła krzemionki12
  • Palenie tytoniu – przyspiesza progresję choroby i zwiększa ryzyko powikłań123
  • Wiek – starszy wiek w momencie ekspozycji może wiązać się z szybszą progresją1
  • Choroby współistniejące – inne schorzenia płuc mogą przyspieszać progresję1
  • Stopień wyjściowych zmian radiologicznych – bardziej nasilone zmiany w początkowych badaniach obrazowych wiążą się z większym ryzykiem progresji1

Tempo progresji w różnych typach pylicy krzemowej

Tempo progresji znacząco różni się w zależności od typu pylicy krzemowej:12

  • Ostra pylica krzemowa: bardzo szybka progresja, objawy rozwijają się w ciągu kilku tygodni do kilku lat od intensywnej ekspozycji, a niewydolność oddechowa może wystąpić w ciągu 1-2 lat123
  • Przyspieszona pylica krzemowa: średnie tempo progresji, objawy rozwijają się w ciągu 3-10 lat od ekspozycji, szybciej niż w postaci przewlekłej12
  • Przewlekła pylica krzemowa: najwolniejsza progresja, objawy rozwijają się stopniowo przez wiele lat, nawet 10-30 lat po pierwszej ekspozycji123

Badania wskazują, że około 37% pacjentów z pylicą krzemową wykazuje radiologiczne cechy progresji choroby podczas obserwacji. Progresja jest bardziej prawdopodobna u osób z początkowo bardziej nasilonymi zmianami radiologicznymi – około 31,6% osób z kategorią 1 zmian, 37,5% z kategorią 2 i aż 52% z powikłaną pylicą krzemową wykazało progresję w badaniach radiologicznych.1

Powikłania pylicy krzemowej

Pylica krzemowa zwiększa ryzyko rozwoju wielu poważnych powikłań i chorób towarzyszących, które mogą znacząco wpłynąć na jakość życia pacjenta i rokowanie.123

Powikłania płucne

Najczęstsze powikłania płucne to:123

Powikłania ogólnoustrojowe

Pylica krzemowa może również prowadzić do powikłań poza układem oddechowym:12

Niewydolność oddechowa

W zaawansowanych stadiach pylicy krzemowej może rozwinąć się niewydolność oddechowa – stan, w którym płuca nie są w stanie zapewnić odpowiedniej wymiany gazowej w organizmie. Objawy niewydolności oddechowej w przebiegu pylicy krzemowej to:123

  • Znaczna duszność, nawet w spoczynku12
  • Sinica (sine zabarwienie skóry i błon śluzowych)12
  • Nadmierna senność lub splątanie12
  • Tachypnoe (przyspieszone oddychanie)12
  • Nieprawidłowości w gazometrii krwi tętniczej (obniżone pO2, podwyższone pCO2)12

Niewydolność oddechowa jest poważnym powikłaniem, które może prowadzić do śmierci pacjenta. W najcięższych przypadkach może być konieczne podawanie tlenu, wentylacja mechaniczna lub nawet przeszczep płuc.12

Prognozy i rokowanie

Rokowanie w pylicy krzemowej zależy od wielu czynników, w tym typu choroby, nasilenia objawów, czasu trwania i intensywności ekspozycji na krzemionkę, wieku pacjenta, chorób współistniejących oraz dostępu do opieki medycznej.12

Oczekiwana długość życia

Pylica krzemowa może znacząco wpłynąć na oczekiwaną długość życia pacjentów. Według badań, osoby z rozpoznaną pylicą krzemową tracą średnio 11,6 lat życia.1

Rokowanie różni się w zależności od typu pylicy:123

  • Ostra pylica krzemowa: najgorsze rokowanie, często prowadzi do śmierci w ciągu 1-2 lat od rozpoznania12
  • Przyspieszona pylica krzemowa: pośrednie rokowanie, szybsza progresja niż w postaci przewlekłej12
  • Przewlekła pylica krzemowa: najlepsze rokowanie, choroba postępuje powoli przez wiele lat, choć z czasem może prowadzić do znacznego upośledzenia funkcji płuc12

Pacjenci z progresywnym masywnym zwłóknieniem (PMF) mają gorsze rokowanie ze względu na znaczne uszkodzenie tkanki płucnej i wysokie ryzyko rozwoju niewydolności oddechowej.12

Jakość życia

Pylica krzemowa znacząco wpływa na jakość życia pacjentów. W miarę postępu choroby mogą oni doświadczać:12

  • Trudności z wykonywaniem codziennych czynności12
  • Problemów z chodzeniem, wchodzeniem po schodach12
  • Ograniczeń w aktywności fizycznej12
  • Konieczności korzystania z dodatkowego tlenu12

W najcięższych przypadkach pacjenci mogą być zmuszeni do pozostawania w domu lub w łóżku przez większość czasu, co prowadzi do całkowitej niepełnosprawności.12

Wpływ leczenia na progresję

Chociaż pylica krzemowa jest nieuleczalna, odpowiednie leczenie może spowolnić progresję choroby i złagodzić objawy, poprawiając jakość życia pacjenta i potencjalnie przedłużając jego życie.123

Kluczowe elementy leczenia, które mogą wpłynąć na rokowanie, to:123

  • Całkowite zaprzestanie narażenia na pył krzemionkowy12
  • Wczesne rozpoznanie i leczenie powikłań, takich jak infekcje dróg oddechowych12
  • Zaprzestanie palenia tytoniu12
  • Tlenoterapia u pacjentów z hipoksemią1
  • Rehabilitacja pulmonologiczna1
  • W wybranych przypadkach ciężkiej choroby – przeszczep płuc12

Przeszczep płuc może być opcją dla niektórych pacjentów z krańcowym stadium choroby, jednak wiąże się z dużym ryzykiem i ograniczoną dostępnością. Badania wykazały, że odsetek 3-letniego przeżycia po przeszczepie płuc u pacjentów z pylicą krzemową wynosi około 76%.1

Warto podkreślić, że regularny monitoring i wczesne wykrycie choroby mogą znacząco wpłynąć na rokowanie. Badania przesiewowe i nadzór medyczny pracowników narażonych na pył krzemionki są kluczowe dla wczesnego rozpoznania choroby i zapobiegania jej progresji.12

    https://www.cdc.gov/niosh/silica/symptoms/index.html
    Breathing in dust from crystalline silica-containing materials can lead to lung disease. This condition is called silicosis. Silicosis results in permanent lung damage and is a progressive, debilitating, and sometimes fatal disease. […] Chronic silicosis typically occurs after 10 or more years of exposure to respirable crystalline silica. However, the disease can occur much more quickly after heavy exposures. Silicosis can develop or progress even after workplace exposures have stopped. Symptoms of silicosis my include: Cough, Fatigue, Shortness of breath, Chest pain. […] Medical monitoring or worker surveillance can help identify health effects related to respirable crystalline silica exposure. An important concern is the risk of developing silicosis, a progressive and irreversible lung disease.

    Silicosis is a respiratory disease. It occurs from long-term inhalation of respirable crystalline silica dust. […] There are three types of silicosis: […] Acute silicosis: Short-term exposure to very large amounts of silica that inflame the lungs, causing them to fill with fluid. This results in severe shortness of breath and low blood oxygen levels. […] Accelerated silicosis: Exposure to large amounts of silica over a period (5-15 years). This results in inflammation, scarring, and symptoms that rapidly progress. […] Simple chronic silicosis: Occurs from long-term exposure (greater than 20 years) to small amounts of silica dust. This results in inflamed nodules and scarring in the lungs and chest lymph nodes. This form of silicosis may resemble chronic obstructive pulmonary disease (COPD).

    Silicosis is a lung disease caused by breathing in (inhaling) silica dust. […] Three types of silicosis occur: […] Chronic silicosis results from long-term exposure (more than 20 years) to low amounts of silica dust. The silica dust causes swelling in the lungs and chest lymph nodes. This disease may cause people to have trouble breathing. This is the most common form of silicosis. […] Accelerated silicosis occurs after exposure to larger amounts of silica over a shorter period of time (3 to 10 years). Swelling in the lungs and symptoms occur faster than in simple silicosis. […] Acute silicosis results from short-term exposure to very large amounts of silica. The lungs become very inflamed and can fill with fluid, causing severe shortness of breath and a low blood oxygen level. […] Symptoms include: Cough, Shortness of breath, Weight loss.
  • #1 Symptoms and Medical Monitoring | Silica | CDC
    https://www.cdc.gov/niosh/silica/symptoms/index.html
    As lung tissue turns into scar tissue with silicosis, reduced lung function occurs and gets progressively worse, even after dust exposure has ended. […] The time from initial exposure to when symptoms first appear (the latency period) depends on duration and intensity of exposure. Higher exposures result in shorter latency periods and faster disease development. […] The type with the quickest onset is acute silicosis. This can occur after a few weeks or months of exposure to very high levels of silica. Acute silicosis causes parts of the lung fill with fluid typically causing severe illness or death. […] Periodic medical monitoring helps to detect silicosis at early stages. This is important so workers can avoid further exposure and limit disease progression.

    Silicosis is an interstitial lung disease caused by breathing in tiny bits of silica, a common mineral found in many types of rock and soil. […] When silica dust enters the lungs, it causes inflammation which over time leads to the development of scar tissue that makes breathing difficult. […] Over time, the silica dust particles can cause lung inflammation that leads to the formation of lung nodules and scarring in the lungs called pulmonary fibrosis. This is a progressive disease that normally takes 10-30 years after first exposure to develop. […] Over time, lung capacity decreases, and people with silicosis particularly those with Progressive Massive Fibrosis may need support with oxygen and other devices to help them breathe. […] In some silicosis cases, this scarring can be so severe that it leads to a form of severe fibrosis, known as Progressive Massive Fibrosis (PMF). For these patients, extreme scarring and stiffening of the lung can make it difficult to breathe. Having silicosis also increases the risk of other health problems, including tuberculosis, lung cancer and chronic bronchitis.
  • #1 Silicosis
    https://www.nhs.uk/conditions/silicosis/
    Silicosis usually develops after being exposed to silica for 10-20 years, although it can sometimes develop after 5-10 years of exposure. […] The symptoms of silicosis usually take many years to develop, and you may not notice any problems until after you’ve stopped working with silica dust. […] The main symptoms of silicosis are: a persistent cough, persistent shortness of breath, weakness and tiredness. […] If the condition continues to get worse, these symptoms may become more severe. […] Some people may eventually find simple activities such as walking or climbing stairs very difficult and may be largely confined to their house or bed. […] The condition can ultimately be fatal if the lungs stop working properly (respiratory failure) or serious complications develop, but this is rare in the UK. […] The condition may continue to get worse, leading to further lung damage and serious disability, although this may happen very slowly over many years.

    Silicosis is a serious chronic (ongoing) lung condition caused by silica dust. […] Over time your lungs can become damaged, making it hard to breathe. […] In the early stages of silicosis, there may be no symptoms. […] Some common symptoms of silicosis are ongoing shortness of breath, persistent or chronic cough, weakness and tiredness, chest pain, and weight loss. […] The symptoms slowly get worse over time, even if you stop breathing in silica dust. […] Unfortunately, if you have silicosis the damage to your lungs cannot be cured.

    https://my.clevelandclinic.org/health/diseases/22622-silicosis
    Inhaling silica (silicon dioxide) particles leads to scarring (fibrosis) in the lungs of people with silicosis. Three symptoms of silicosis, a work-related lung disease, are inflammation (swelling), fibrosis (scarring) and coughing. […] If you have it, you’ll have symptoms of coughing, inflammation (swelling) and fibrosis (scarring). […] There are three main symptoms of silicosis: Persistent coughing, Coughing that brings up sputum, Inflammation (swelling), Fibrosis (scarring). […] These signs and symptoms can cause: Shortness of breath (dyspnea), Fatigue, Weakness, Unintended weight loss. […] Your outlook depends on many factors, including how much silica you’ve been exposed to and the length of time you were exposed. Your age and whether you have other diseases matter, as does whether or not your exposure continues. […] The outlook for people who develop progressive massive fibrosis is less positive.
  • #1 Silicosis Symptoms and Diagnosis | American Lung Association
    https://www.lung.org/lung-health-diseases/lung-disease-lookup/silicosis/symptoms-diagnosis
    Symptoms of silicosis usually appear after many years of exposure. In early stages, symptoms are mild and include cough, sputum and progressive shortness of breath. […] Once the lung scarring has become more severe, there are a variety of symptoms that may appear. These commonly include bronchitis-like symptoms such as persistent cough, shortness of breath and difficulty breathing. People also suffer from weakness, fatigue, fever, night sweats, leg swelling and bluish discoloration of the lips. […] The longer silicosis goes without treatment, the more likely it is to develop a complication. Because the disease affects the immune system, silicosis patients are vulnerable to developing tuberculosis, lung cancer, COPD and kidney disease.
  • #1 Silicosis Symptoms
    https://silicosis.org.au/about-silicosis/silicosis-symptoms/
    A dry, persistent cough is one of the earliest signs of lung irritation. Over time, this may develop into a productive cough (with mucus) as your lungs try to clear out irritants. […] At first, you might only notice it during exercise or physical activity, like climbing stairs. But as the disease progresses, breathlessness can happen even when you’re resting. […] As airflow through the lungs becomes restricted, it can cause a wheezing or whistling sound when you breathe. […] People with silicosis often describe a “heavy” or “tight” feeling in the chest, which makes it harder to take a deep breath. […] Fatigue is a common sign of lung disease. As your lungs have to work harder to get oxygen into your blood, your energy levels drop. […] It’s common for people to have no symptoms of silicosis until significant lung damage has already occurred. […] However, through health monitoring and lung screening programs, lung damage can be detected before symptoms develop. This allows for medical intervention, lifestyle changes, and possible removal from high-risk work environments.

  • #1 Silicosis: Background, Pathophysiology, Epidemiology
    https://emedicine.medscape.com/article/302027-overview
    Silicosis is a primary pneumoconiosis involving fibronodular lung disease caused by inhalation of silica dust. The clinical picture of silicosis is variable, with three classified types. Acute (weeks to years of exposure) and chronic/classic forms (10-30 years after exposure), as well as accelerated silicosis (10 years of high-level exposure), have been recognized based on the duration of exposure to silica and on the latency of the symptoms. Complications of silicosis can cause related morbidity. As the disease progresses, airflow limitation occurs, manifested by dyspnea and cough, and results in chronic bronchitis. Eventually, cor pulmonale and respiratory failure develop. Progressive massive fibrosis (PMF) occurs in 18%-37% of workers over an average of 5 years of exposure. Smoking and continued silica exposures play a significant role in the radiologic progression of silicosis, from simple to chronic, as well as PMF. Patients who had profound silica exposure over a relatively shorter time course may develop accelerated silicosis. This entity is typically related to an exposure history of 5 to 15 years, usually 10 years or less. Disease progression may continue despite cessation of silica exposure. Patients with chronic silicosis may be asymptomatic despite potentially decades of exposure to silica dust. A subset of these patients, however, may develop progressive massive fibrosis (PMF). Retractions of PMF may cause emphysematous changes in the basilar lung regions. These patients are prone to develop hypoxic respiratory failure, mycobacterial infections, and pneumothoraces. Cause of death is invariably respiratory failure.
  • #1 Silicosis – StatPearls – NCBI Bookshelf
    https://www.ncbi.nlm.nih.gov/books/NBK594245/
    Silicosis is characterized by irreversible, progressive pulmonary fibrosis leading to restrictive lung disease. […] Silicosis occurs secondary to the inhalation of respirable crystalline silica (RCS) and causes progressive, irreversible, and fatal lung inflammation and fibrosis.

    Silicosis symptoms dont appear right away in most cases, usually taking several years to develop working with silica dust. However, studies indicate that symptoms of silicosis due to exposure to artificial stone appear quicker than exposure to natural silica sources, potentially due to the higher concentration of silica in artificial stone. […] There are three types of silicosis: acute (most commonly caused by working with artificial stone), accelerated and chronic, depending on the level of exposure to silica dust, according to the Centers for Disease Control and Prevention, which explains the severity of each type on its website. […] Complications from silicosis can include tuberculosis, lung cancer, chronic bronchitis, kidney disease and autoimmune disorders. In some cases, silicosis can cause severe scarring of the lung tissue, leading to a condition called progressive massive fibrosis, or PMF. Some patients may require a lung transplant. […] Lung damage from silicosis is irreversible, so treatment of silicosis is aimed at slowing down the disease and relieving its symptoms.

    OBJECTIVES To investigate the risk factors predicting radiological progression in silicosis in a prospective cohort study of patients with silicosis who were previously exposed to silica from granite dust. […] RESULTS Overall, 37% of patients with silicosis had radiological evidence of progression. From the initial radiographs, 24 (31.6%) of those with radiological profusion category 1, 15 (37.5%) of those with radiological profusion category 2, and 13 (52%) of those with complicated silicosis (including all seven with category 3 profusion of small opacities) showed radiological progression. […] CONCLUSIONS There is a high probability of radiological progression in silicosis after high levels of exposure to granite dust among workers who were followed up for up to 17 years. A significant risk factor is the extent of radiological opacities in the initial chest x ray film. The probability of progression is also likely to be reduced with longer periods after the end of exposure.

    Patients with simple chronic silicosis are frequently asymptomatic but may present with a dry cough or dyspnea on exertion. […] Complicated chronic silicosis, or pulmonary massive fibrosis (PMF), develops when the pulmonary nodules expand and fuse to form conglomerate masses with a diameter of greater than 10 mm. […] Patients with PMF usually develop debilitating respiratory impairment due to the profound destruction of lung tissue, which results in decreased perfusion capacity, impairment in lung function, and elevated pulmonary resistance. […] The prognosis is poor, with a gradually worsening decline in pulmonary function, often leading to the eventual development of respiratory failure and cor pulmonale.

  • #2 Silicosis: Background, Pathophysiology, Epidemiology
    https://emedicine.medscape.com/article/302027-overview
    Silicosis is a primary pneumoconiosis involving fibronodular lung disease caused by inhalation of silica dust. The clinical picture of silicosis is variable, with three classified types. Acute (weeks to years of exposure) and chronic/classic forms (10-30 years after exposure), as well as accelerated silicosis (10 years of high-level exposure), have been recognized based on the duration of exposure to silica and on the latency of the symptoms. Complications of silicosis can cause related morbidity. As the disease progresses, airflow limitation occurs, manifested by dyspnea and cough, and results in chronic bronchitis. Eventually, cor pulmonale and respiratory failure develop. Progressive massive fibrosis (PMF) occurs in 18%-37% of workers over an average of 5 years of exposure. Smoking and continued silica exposures play a significant role in the radiologic progression of silicosis, from simple to chronic, as well as PMF. Patients who had profound silica exposure over a relatively shorter time course may develop accelerated silicosis. This entity is typically related to an exposure history of 5 to 15 years, usually 10 years or less. Disease progression may continue despite cessation of silica exposure. Patients with chronic silicosis may be asymptomatic despite potentially decades of exposure to silica dust. A subset of these patients, however, may develop progressive massive fibrosis (PMF). Retractions of PMF may cause emphysematous changes in the basilar lung regions. These patients are prone to develop hypoxic respiratory failure, mycobacterial infections, and pneumothoraces. Cause of death is invariably respiratory failure.

    Chronic silicosis can be asymptomatic, but many patients develop progressive dyspnea and cough. […] Patients with progressive massive fibrosis develop severe chronic respiratory symptoms. […] Patients with acute silicosis experience rapid progression of dyspnea, weight loss, and fatigue with diffuse bilateral crackles. These symptoms can be mistaken for a lung infection. Hypoxemia and respiratory failure are common. […] Chronic silicosis generally progresses insidiously and can advance to progressive massive fibrosis and respiratory impairment.

    Patients with silicosis are particularly susceptible to tuberculosis (TB) infection known as silicotuberculosis. […] Pulmonary complications of silicosis also include chronic bronchitis and airflow limitation (indistinguishable from that caused by smoking), non-tuberculous Mycobacterium infection, fungal lung infection, compensatory emphysema, and pneumothorax. […] Acute silicosis develops a few weeks to 5 years after exposure to high concentrations of respirable silica dust. Symptoms of acute silicosis include more rapid onset of severe disabling shortness of breath, cough, weakness, and weight loss, often leading to death.

    OBJECTIVES To investigate the risk factors predicting radiological progression in silicosis in a prospective cohort study of patients with silicosis who were previously exposed to silica from granite dust. […] RESULTS Overall, 37% of patients with silicosis had radiological evidence of progression. From the initial radiographs, 24 (31.6%) of those with radiological profusion category 1, 15 (37.5%) of those with radiological profusion category 2, and 13 (52%) of those with complicated silicosis (including all seven with category 3 profusion of small opacities) showed radiological progression. […] CONCLUSIONS There is a high probability of radiological progression in silicosis after high levels of exposure to granite dust among workers who were followed up for up to 17 years. A significant risk factor is the extent of radiological opacities in the initial chest x ray film. The probability of progression is also likely to be reduced with longer periods after the end of exposure.

    The introduction of artificial stone (AS) in industries that handled marble has caused a significant increase in silicosis cases. […] The aim of the study was to analyze the clinical, functional, radiological and occupational evolution of a series of AS silicotic patients referred from an occupational health company. […] The most frequent clinical presentation was dyspnoea in 15 of the patients (46.9%). Nine patients (28.1%) had no symptoms. […] Evolution was followed for 39.634.5 months. Three patients (9.3%) progressed from simple to complicated and 1 patient presented an accelerated course. At the end of follow-up, 17 (53.1%) patients were classified as complicated silicosis. Additionally, 10 (31.3%) patients worsened clinically and 14 (43.8%) functionally. […] A 43.8% of our patients experienced a significant decrease in lung function. FVC and FEV1 declined roughly the same rate, as it has also been mentioned in other silicosis. […] Our data, together with a high demand for lung transplantation suggest a serious aggressiveness.

    Silicosis is an interstitial lung disease caused by breathing in tiny bits of silica, a common mineral found in many types of rock and soil. […] When silica dust enters the lungs, it causes inflammation which over time leads to the development of scar tissue that makes breathing difficult. […] Over time, the silica dust particles can cause lung inflammation that leads to the formation of lung nodules and scarring in the lungs called pulmonary fibrosis. This is a progressive disease that normally takes 10-30 years after first exposure to develop. […] Over time, lung capacity decreases, and people with silicosis particularly those with Progressive Massive Fibrosis may need support with oxygen and other devices to help them breathe. […] In some silicosis cases, this scarring can be so severe that it leads to a form of severe fibrosis, known as Progressive Massive Fibrosis (PMF). For these patients, extreme scarring and stiffening of the lung can make it difficult to breathe.

    Silicosis is a lung disease caused by the inhalation of respirable crystalline silica dust, a common mineral found in materials such as sand, stone, concrete, and mortar. […] Silicosis is a progressive, disabling, and often fatal lung disease. […] Silicosis develops when workers inhale fine crystalline silica dust, which causes fibrotic nodules to scar and inflame lung tissue. […] The fibrotic development involved with silicosis can impede breathing, causing lung damage and respiratory illnesses. […] Symptoms of weight loss, shortness of breath, fatigue and chest pain develop between two months to two years. […] Accelerated silicosis develops after 5 to 10 years of intense exposure, and symptoms take much longer to appear. […] Chronic silicosis, the most common form of the disease, develops after 15 to 20 years of low to medium levels of exposure. […] Exposure to silicosis can cause respiratory damage and other health complications, such as chronic bronchitis, kidney failure, and lung cancer.

    There are three types of silicosis, and each type affects the body differently. […] Acute silicosis occurs within a few weeks or years of silica exposure and symptoms include cough, weight loss, tiredness, sharp chest pain, and breathlessness. […] Chronic silicosis occurs 10 to 30 years after silica exposure and symptoms include inflamed lungs, fluid build-up, breathlessness, and low blood oxygen. […] Accelerated silicosis occurs within 10 years of frequent silica exposure and symptoms include swelling in the lungs, swelling in the chest lymph nodes, and difficulty breathing.

    Symptoms of silicosis affect the respiratory system and may vary depending on the severity of the disease. […] However, early silicosis symptoms may include: A cough that does not go away, Shortness of breath, Weakness and fatigue. […] As silicosis progresses, symptoms can worsen to severe chest pain, weight loss, and even respiratory failure. […] Silicosis usually happens after being exposed to silica for 10 to 20 years. However, it can sometimes develop after just 5 to 10 years of exposure. […] Unfortunately, the lung damage from silicosis is irreversible. However, treatments like oxygen therapy, pulmonary rehabilitation, and medications can improve your quality of life and life span. […] Because crystalline silica dust can remain in the body for decades, silicosis often progresses or worsens over time as scarring continues to build up in the lungs.
