Choroba gauchera
Epidemiologia

Choroba Gauchera (GD) to autosomalne recesywne zaburzenie lizosomalne, charakteryzujące się akumulacją glukocerebrozydów w makrofagach, głównie w kościach, szpiku, wątrobie i śledzionie. Globalna prewalencja wynosi około 0,9 (95% CI: 0,7–1,1) na 100 000 osób, a częstość urodzeń to 1,5 (95% CI: 1,0–2,0) na 100 000 żywych urodzeń. Choroba wykazuje zróżnicowanie etniczne – w populacji ogólnej częstość występowania wynosi 1:40 000–1:100 000, natomiast wśród Żydów aszkenazyjskich jest znacznie wyższa (1:450–1:1000), z nosicielstwem na poziomie 1:12–17. W Izraelu standaryzowana częstość występowania osiąga 11,6 na 100 000 osób (95% CI: 11,0–12,1). Wyróżnia się trzy typy choroby: typ 1 (nieneuropatyczny, ~90% przypadków, częstość 1–9/100 000), typ 2 (ostra postać neuropatyczna, ~1:150 000) oraz typ 3 (podostra postać neuropatyczna, ~1:200 000), z regionalnymi różnicami w dystrybucji, np. wysoka częstość typu 3 w Norrbotten (1:50 000) i Egipcie (62% przypadków).

Epidemiologia choroby Gauchera

Choroba Gauchera (GD) jest rzadkim, autosomalnym recesywnym zaburzeniem lizosomalnym, charakteryzującym się postępującym magazynowaniem glukocerebrozydów w makrofagach, głównie w kościach, szpiku kostnym, wątrobie i śledzionie. Jest to najczęściej występująca choroba spichrzeniowa lizosomów, pomimo swojej ogólnej rzadkości.12 Dane epidemiologiczne dotyczące choroby Gauchera są ograniczone, zwłaszcza dla poszczególnych typów tej choroby, co stanowi znaczące wyzwanie w dokładnym określeniu jej globalnego obciążenia.3

Globalna częstotliwość występowania

Według najnowszych danych, globalna częstość występowania choroby Gauchera waha się od 0,7 do 1,8 na 100 000 osób.4 Metaanaliza opublikowana w 2023 roku wykazała, że globalna prewalencja choroby Gauchera wynosi 0,9 przypadków (95% przedział ufności: 0,7 do 1,1) na 100 000 mieszkańców.5 Dane te opierają się na analizie wyników z 4 badań obejmujących 3 kraje/regiony.6

Częstość urodzeń (birth prevalence) chorych z chorobą Gauchera została oszacowana na 1,5 przypadków (95% przedział ufności: 1,0 do 2,0) na 100 000 żywych urodzeń według tej samej metaanalizy.7 Dane te zostały wyekstrahowane z 16 badań obejmujących 14 krajów/regionów.8 Inne badania podają, że standaryzowana częstość urodzeń w populacji ogólnej waha się od 0,4 do 5,8 na 100 000 żywych urodzeń.9

Różnice etniczne w występowaniu

Częstość występowania choroby Gauchera wykazuje znaczne różnice w zależności od grupy etnicznej. Choroba ta jest szczególnie rozpowszechniona wśród Żydów aszkenazyjskich (pochodzących z Europy Wschodniej i Centralnej).1011

  • W populacji ogólnej: częstość występowania wynosi około 1 na 40 000 do 1 na 100 000 osób1213
  • W populacji Żydów aszkenazyjskich: częstość występowania wynosi około 1 na 450-1000 osób1415
  • Częstość nosicielstwa wśród Żydów aszkenazyjskich: około 1 na 12-17 osób1617

W Izraelu, gdzie zamieszkuje duża populacja Żydów aszkenazyjskich, standaryzowana częstość występowania choroby Gauchera osiąga 11,6 na 100 000 osób (95% CI: 11,0 do 12,1), co jest wartością 10-krotnie wyższą niż wskaźniki raportowane na całym świecie.18

Rozpowszechnienie poszczególnych typów choroby Gauchera

Choroba Gauchera dzieli się na trzy główne typy, różniące się epidemiologią, aktywnością enzymatyczną i manifestacjami klinicznymi:19

Typ 1 (nieneuropatyczny)

Typ 1 jest najczęstszą formą choroby Gauchera, stanowiącą około 90% wszystkich przypadków w Stanach Zjednoczonych, Europie i Izraelu.2021 Jest to forma nieneuropatyczna, charakteryzująca się powiększeniem narządów wewnętrznych, zajęciem kości i cytopenią.22

  • Częstość występowania: 1-9 na 100 000 osób w populacji ogólnej23
  • Częstość występowania w populacji nieżydowskiej: około 1 na 40 000 do 1 na 86 000 żywych urodzeń24
  • Częstość występowania wśród Żydów aszkenazyjskich: około 1 na 850 osób25

Według danych z celowanego przeglądu literatury z 2022 roku, częstość występowania typu 1 choroby Gauchera waha się od 0,26 do 0,63 na 100 000 osób.26

Typ 2 (ostra postać neuropatyczna)

Typ 2 charakteryzuje się ostrym przebiegiem z zajęciem układu nerwowego i występuje z podobną częstością we wszystkich grupach etnicznych.27

  • Szacowana częstość występowania: około 1 na 150 000 w populacji ogólnej28
Typ 3 (podostra postać neuropatyczna)

Typ 3 jest częstszy w niektórych regionach geograficznych, takich jak północna Szwecja (region Norrbotten), Egipt i części Azji.29

  • Częstość występowania w regionie Norrbotten w Szwecji: około 1 na 50 000 osób3031
  • Częstość występowania w populacji ogólnej: około 1 na 200 000 osób32

Warto zauważyć, że w niektórych krajach występuje odmienny wzorzec dystrybucji typów choroby Gauchera. Na przykład, w Egipcie typ 3 jest częstszy niż typ 1, podczas gdy typ 2 jest rzadki. W egipskiej kohorcie 216 pacjentów z ośmiu ośrodków leczenia, odsetek typu 1, typu 2 i typu 3 wynosił odpowiednio 30,5%, 7,5% i 62%.33

Typ choroby Gauchera Częstość występowania w populacji ogólnej Charakterystyka Szczególne grupy ryzyka
Typ 1 (nieneuropatyczny) 1-9/100 000; ~90% wszystkich przypadków Brak zajęcia układu nerwowego; powiększenie narządów, zajęcie kości, cytopenia Żydzi aszkenazyjscy (1:850)
Typ 2 (ostra postać neuropatyczna) ~1:150 000 Ciężkie zajęcie neurologiczne o ostrym przebiegu Brak preferencji etnicznych
Typ 3 (podostra postać neuropatyczna) ~1:200 000; ~5% wszystkich przypadków Podostra forma z zajęciem neurologicznym Region Norrbotten w Szwecji (1:50 000), Egipt (62% wszystkich przypadków GD), części Azji

Wyzwania w diagnostyce i nadzorze epidemiologicznym

Choroba Gauchera stawia szereg wyzwań w kontekście monitorowania epidemiologicznego i wczesnej diagnostyki, co wpływa na dokładność dostępnych danych dotyczących jej częstości występowania.34

Wczesna diagnostyka i świadomość choroby

Wielu pacjentów z chorobą Gauchera doświadcza długotrwałej „odysei diagnostycznej”, co może negatywnie wpływać na dostęp do opieki i wyniki kliniczne.35 Heterogenność objawów, złożoność molekularna locus GBA1, niska częstość występowania choroby oraz ograniczona wiedza wśród lekarzy stanowią barierę dla wczesnej diagnostyki.36

Badania wykazały niski poziom świadomości choroby Gauchera wśród lekarzy. W badaniu przeprowadzonym w siedmiu krajach wśród 406 hematologów-onkologów tylko 20% początkowo rozważało chorobę Gauchera u pacjenta prezentującego typowe objawy, takie jak anemia, trombocytopenia, hepatomegalia, splenomegalia i ból kości.37

Programy badań przesiewowych noworodków

Programy badań przesiewowych noworodków (Newborn Screening, NBS) mogą pomóc w wcześniejszym wykrywaniu choroby Gauchera.38 Jednak obecnie choroba Gauchera nie jest uwzględniona w Recommended Uniform Screening Panel (RUSP) w Stanach Zjednoczonych, a decyzje o jej włączeniu do programów przesiewowych podejmowane są na poziomie stanowym.39

Obecnie badania przesiewowe w kierunku choroby Gauchera są prowadzone tylko w sześciu stanach USA: Illinois, Missouri, New Jersey, Nowy Meksyk, Oregon i Tennessee, a także w ramach pilotażowego programu ScreenPlus w Nowym Jorku.4041 Niektóre kraje, jak Tajwan, wprowadziły badania przesiewowe w kierunku choroby Gauchera od 2015 roku, co doprowadziło do wcześniejszego rozpoznawania i zmiany w rozkładzie podtypów choroby.42

Nadzór i monitorowanie pacjentów

Pacjenci z chorobą Gauchera typu 1 wymagają regularnych kontroli w celu monitorowania progresji choroby. Obejmuje to badania krwi, pomiary śledziony i wątroby oraz skany szkieletowe, zazwyczaj wykonywane co 3-24 miesiące, w zależności od stanu pacjenta i zaleceń lekarza.43

Powstały także liczne rejestry pacjentów, które przyczyniają się do lepszego zrozumienia historii naturalnej choroby i odpowiedzi na leczenie. Przykładem jest Francuski Rejestr Choroby Gauchera (FGDR), który zidentyfikował 562 pacjentów z chorobą Gauchera we Francji.44 W Wielkiej Brytanii kohorta GAUCHERITE obejmuje 85% wszystkich pacjentów z chorobą Gauchera w tym kraju i stanowi platformę do badania epidemiologii i przebiegu tego heterogennego zaburzenia.45

Wyzwania w krajach o niskim dochodzie

Dostępność danych epidemiologicznych dotyczących choroby Gauchera prawdopodobnie odzwierciedla dostęp do opieki zdrowotnej, ponieważ diagnoza tej choroby wymaga zastosowania technik, które są zarówno inwazyjne, jak i wymagające dużych zasobów.46 W krajach o niskim dochodzie, takich jak Mozambik, który znajduje się w dolnych 10 pozycjach globalnego wskaźnika rozwoju ludzkiego, wprowadzenie protokołu diagnostycznego i leczniczego dla choroby Gauchera w krajowym systemie zdrowia nie jest obecnie możliwe ze względu na wysokie koszty.47

Tendencje i przyszłość nadzoru epidemiologicznego

Globalne badanie kohortowe analizujące ponad 15 000 pacjentów z chorobą Gauchera wykazało znacząco wyższe wskaźniki zapadalności i chorobowości w ostatnich latach, prawdopodobnie z powodu lepszego rozpoznawania choroby i dostępu do leczenia.48 Częstość występowania choroby Gauchera wzrosła z 0,017% w 2000 roku do 0,036% w 2020 roku, podczas gdy zapadalność wzrosła z 0,006% do 0,012% w tym samym okresie.49

Choroby płuc i układu oddechowego są główną przyczyną zachorowalności i śmiertelności w chorobie Gauchera. Nawet do 100% pacjentów z chorobą Gauchera rozwija patologię płuc w ciągu życia, a 6,2% umiera z powodu powikłań płucnych.50 Pomimo tego znacznego obciążenia, dane dotyczące częstości występowania manifestacji oddechowych są ograniczone.51

Szacunki populacyjne w określonych punktach czasowych mogą stanowić użyteczny punkt odniesienia, na podstawie którego można monitorować przyszłe zmiany w częstości występowania i zapadalności na chorobę Gauchera oraz śledzić pojawianie się nowych wariantów genetycznych związanych z chorobą Gauchera, identyfikowanych poprzez profilowanie genetyczne.52

W przyszłości potrzebne są dalsze badania, aby lepiej zrozumieć epidemiologię choroby Gauchera, zwłaszcza w regionach, gdzie dane są ograniczone, takich jak Chiny, Indie, Indonezja, Bliski Wschód i Afryka.53 Istnieje także potrzeba lepszego zrozumienia związku między genotypem a fenotypem oraz opracowania skutecznych terapii dla postaci neuropatycznych choroby.54

Prognozy rynkowe i badania kliniczne

Według prognoz rynkowych, wartość rynku choroby Gauchera w siedmiu głównych krajach (USA, Francja, Niemcy, Włochy, Hiszpania, Wielka Brytania i Japonia) wynosiła 1,22 miliarda dolarów w 2022 roku, z przewidywanym stabilnym wzrostem o mniej niż 1% CAGR w latach 2022-2032.55

Główne czynniki wpływające na wzrost rynku to:56

  • Poprawa świadomości lekarzy
  • Zmniejszenie niechęci pacjentów do uczestnictwa w diagnostyce i leczeniu, szczególnie w populacji Żydów aszkenazyjskich
  • Zwiększone włączenie choroby Gauchera do paneli badań przesiewowych noworodków
  • Szersze przyjęcie badań przesiewowych noworodków

Według stanu na maj 2024 roku, przeprowadzono łącznie 151 badań klinicznych dotyczących choroby Gauchera.57 Obecnie dominującą klasą leków na rynku choroby Gauchera jest enzymatyczna terapia zastępcza (ERT), a główne firmy działające na tym rynku to Sanofi i Takeda.58

    Gaucher disease is the most prevalent LSD, with an incidence of 1 case per 40,000–60,000 births in the general population; however, it can occur in 1–800 births within the Ashkenazi Jewish population. […] A meta-analysis by Wanh Meimei in 2023 reported a global prevalence of GD at 1.5 cases per 100,000 live births. […] The first records of Gaucher disease in Mexico were from 1966 at the Centro Médico Nacional “La Raza” of the Instituto Mexicano del Seguro Social (IMSS). […] By 2005, a general census identified 68 cases residing in the states of Sinaloa, Nuevo León, Michoacán, Morelos, Jalisco, Puebla, Baja California Sur, Coahuila, and Mexico City. […] In a cohort from 2021 including GD cases from México and Spain, type 1 GD was reported to be more common among the Mexican population. […] This disease is among the 20 rare diseases recognized in Mexico.

    Gaucher disease (GD) is a rare, autosomal recessive disorder.1 Although rare, it is the most common type of lysosomal storage disease.1 […] There are three types of GD. Type 1 Gaucher disease (GD1) is the most prevalent form of the disease, accounting for more than 90% of all cases.4 […] GD1 is a pan-ethnic condition, although it does have a higher prevalence in people of Ashkenazi Jewish ancestry.5 […] GD1 affects: 19 in 100,000 within the overall population12 […] ~1 in 600 within the Ashkenazi Jewish population3 […] ~1 in 17 within the Ashkenazi Jewish community that are carriers13 […] an estimated 6,000 individuals in the United States3,14 […] GD1 is genetic and has an autosomal recessive inheritance pattern.3 If both parents are carriers, there is a 50% chance of the child being a carrier, a 25% chance of them having Gaucher disease, and a 25% chance that they will not be affected.3
  • #3 Global Incidence and Prevalence of Gaucher Disease: A Targeted Literature Review
    https://pmc.ncbi.nlm.nih.gov/articles/PMC9821068/
    There is a need for a better understanding of the global incidence and prevalence of GD, together with an evaluation of incidence rates for specific ethnic populations found within each geographic region. […] The objective of this targeted review was to provide a qualitative synthesis of global GD incidence and prevalence estimates by region, overall, and by disease type, published in the last 10 years. […] GD incidence was poorly documented overall, and GD type-specific estimates for incidence and prevalence were rare. Few estimates were available for GD2 and GD3. […] The regional generalizability of prevalence estimates was considered adequate for North America, Europe, Latin America, and the Asia-Pacific region and intermediate for the Middle East (because no estimates were found for Egypt or Turkey, two of the four countries of the region with the largest population sizes). […] The synthesis of GD incidence and prevalence estimates by region in this review highlighted significant data gaps.

    Gaucher disease (GD) is one of the most common lysosomal diseases. Type 1 GD (GD1) is the most prevalent type in the United States, Europe, and Israel and occurs with greater frequency in the Ashkenazi Jewish population. Type 2 GD (GD2) occurs in all ethnic types. There were approximately 20,000 individuals with GD in the United States in the mid-1990s based upon a gene frequency study, two-thirds of whom were Ashkenazi Jews, although fewer reached medical attention. A subsequent survey estimated the standardized birth incidence of GD in the general population to be between 0.4 and 5.8 per 100,000, with a prevalence of 0.7 to 1.8 per 100,000. […] In the United States, Europe, and Israel, approximately 90 percent of patients have GD1, which is the nonneuronopathic form. GD1 is the most common type seen in the Ashkenazi Jewish population, although most patients with GD1 are not Jewish. The carrier frequency in the Ashkenazi Jewish population is approximately 1 in 12, and the frequency of disease-associated genotypes is calculated at 1 in 850. The incidence of GD1 is much lower in non-Jewish populations, occurring in approximately 1 in 40,000 to 1 in 86,000 live births. […] GD2 (also called acute neuronopathic GD) has an estimated incidence of 1 in 150,000.

  • #11 Gaucher Disease: Practice Essentials, Background, Pathophysiology
    https://emedicine.medscape.com/article/944157-overview
    Mortality and morbidity varies with the different types. Type 1 Gaucher disease may present in childhood with hepatosplenomegaly, pancytopenia, and skeletal disease, although there is striking clinical variability in disease severity. Prior to the advent of treatment, bleeding and hepatic complications were more common, and patients with severe splenomegaly would routinely undergo splenectomy and have severe, sometimes fatal, bleeding complications. This risk has been dramatically reduced with the development of enzyme replacement therapy (ERT). Bone disease was a common cause of morbidity but is seen less frequently in treated patients. […] All forms of Gaucher disease are panethnic. Type 1 Gaucher disease is one of the most common lysosomal storage diseases and is the most prevalent genetic disorder in individuals of Ashkenazi Jewish descent. Type 3 disease is more common in the Norrbottnian region of Sweden and parts of Asia.

Due to its inheritance pattern, it tends to affect males and females equally. The onset of symptoms can vary depending on disease type and severity with milder forms presenting in adulthood and a significant number of individuals with type 1 never receiving any medical attention. […] GD is generally categorized into 3 types: type 1 is the most prevalent, accounting for more than 90% of all cases, and is characterized by the presence of bone disease and the lack of neurologic features. Type 2 and Type 3 both typically involve neurodegeneration.

    https://bmjopen.bmj.com/content/9/1/e024251
    A total of 500 patients with GD were identified and assessed. […] The incidence of GD in Ashkenazi Jews, the majority of whom reside in Israel, is linked with a high carrier frequency of the mutation N370S of 1 in 17.5 and a disease prevalence of 1 in 850. […] Establishing a population-based cohort of patients with GD is essential to understanding disease progression and management. […] The goal of this study was to characterise a population-based cohort of patients with GD relative to the general population and describe sociodemographic and clinical characteristics by disease severity, as indicated by ERT use. […] The age-standardised prevalence of GD was 11.6 (95% CI 11.0 to 12.1) per 100000. […] The prevalence of GD found in this study is 10-fold higher than reported rates worldwide. […] Among patients with GD, we report an ERT treatment prevalence of 41.2%. […] These findings highlight the need for physicians to monitor patients with GD regardless of their ERT status.

    We conducted a global cohort study analyzing over 15,000 patients with GD to determine how the epidemiology of this rare disorder has evolved over the past 20 years. We found significantly higher incidence and prevalence rates in the latter period, likely due to improved disease recognition and access to treatment. Early diagnosis and optimized management of GD are crucial to prevent morbidity and mortality, though additional research is still needed to fully understand its societal burden. The prevalence of GD increased from 0.017% in 2000 to 0.036% in 2020, while incidence rose from 0.006% to 0.012% over the same period. Pulmonary and respiratory disease are major causes of morbidity and mortality in GD. Up to 100% of GD patients develop lung pathology over their lifetime, and 6.2% die from pulmonary complications. Despite this substantial burden, limited data exist on incidence and prevalence of respiratory manifestations.

  • #52 Global Incidence and Prevalence of Gaucher Disease: A Targeted Literature Review
    https://www.mdpi.com/2077-0383/12/1/85
    Newborn screening programs were developed for several LSDs, aiming to achieve earlier disease detection with a view to improving long-term patient outcomes. […] The objective of this targeted review was to provide a qualitative synthesis of global GD incidence and prevalence estimates by region, overall, and by disease type, published in the last 10 years. […] The synthesis of GD incidence and prevalence estimates by region in this review highlighted significant data gaps. […] The availability of epidemiologic data on GD is likely to reflect accessibility to healthcare, because the diagnosis of GD requires the use of techniques that are both invasive and resource intensive. […] Population estimates at specific time points can provide a useful benchmark from which to monitor future changes in GD incidence and prevalence and for tracking the emergence of new genetic variants associated with GD identified by genetic profiling.
  • #53 Disease Overview – Gaucher Disease
    https://gaucherdiseaseplatform.org/disease-overview/
    Gauchers disease is a pan-ethnic disorder that has had major focus in developed countries with populations of European origin. […] The overall frequency of Gauchers disease variants is about one in 40,000 to one in 60,000 livebirths in the general population. However, there is a higher frequency of Gauchers disease type 1 in the Ashkenazi Jews, about one in 800 livebirths. This has led to characterisation of disease phenotypes mainly on the basis of that population. […] However, the growing recognition of substantial populations with type 1 disease in Asia, South America, the Indian subcontinent, and other demographic areas is broadening our appreciation of the range of phenotypes in this variant. […] Similarly, with the broader recognition of types 2 and 3, widespread variation and range of involvement from early onset has become increasingly evident. […] The general frequencies of any of the variants in large populations of China, India, Indonesia, the Middle East, or Africa are unknown.
  • #54 An Overview of Gaucher Disease | Scilit
    https://www.scilit.com/publications/e3e60e254ba9b9be6e7306aafc0ca640
    Background: Gaucher disease (GD) is a rare autosomal recessive disorder caused by mutations in the GBA1 gene that lead to a deficiency in the glucocerebrosidase gene. This deficiency results in the accumulation of glucocerebrosides in macrophages, primarily affecting the liver, spleen, and bone marrow. Focusing on the Mexican population, this study aims to review GD’s epidemiology, clinical manifestations, and treatment options to enhance early diagnosis and optimize treatment outcomes. […] Continued research is required to enhance therapeutic approaches for the neuropathic types and better understand the disease’s epidemiology in Mexico.
