Choroba pierwotna dróg żółciowych (dawniej nazywana pierwotną marskością dróg żółciowych)
Epidemiologia

Choroba pierwotna dróg żółciowych (PBC) to przewlekła, cholestatyczna choroba autoimmunologiczna wątroby, charakteryzująca się destrukcyjnym zapaleniem małych dróg żółciowych oraz obecnością przeciwciał przeciwmitochondrialnych. Globalna zachorowalność wynosi średnio 1,76/100 000 osób rocznie, a rozpowszechnienie 14,60/100 000 osób, z wyraźnymi różnicami geograficznymi: Ameryka Północna (2,75/100 000 i 21,81/100 000), Europa (1,86/100 000 i 14,59/100 000) oraz region Azji i Pacyfiku (0,84/100 000 i 9,82/100 000). PBC dotyka głównie kobiety (stosunek 4-6:1), z najwyższą zachorowalnością w wieku 60-79 lat, a u mężczyzn choroba jest często diagnozowana później i przebiega agresywniej. Czynniki genetyczne, w tym warianty alleliczne MHC klasy II, oraz czynniki środowiskowe, takie jak palenie tytoniu i hormonalna terapia zastępcza, odgrywają istotną rolę w patogenezie. PBC często współwystępuje z innymi chorobami autoimmunologicznymi, np. zespołem Sjögrena czy autoimmunologiczną chorobą tarczycy, co podkreśla konieczność kompleksowego podejścia diagnostycznego i terapeutycznego.

Epidemiologia choroby pierwotnej dróg żółciowych (dawniej nazywanej pierwotną marskością dróg żółciowych)

Choroba pierwotna dróg żółciowych (PBC, dawniej nazywana pierwotną marskością dróg żółciowych) to przewlekła cholestatyczna autoimmunologiczna choroba wątroby charakteryzująca się destrukcyjnym zapaleniem małych dróg żółciowych i limfocytarnym zapaleniem dróg żółciowych, z obecnością przeciwciał przeciwmitochondrialnych.123 Zachorowalność i rozpowszechnienie PBC różnią się znacznie w zależności od regionu geograficznego i okresu badania.12

Częstotliwość występowania na świecie

Szacowana globalna zachorowalność na PBC wynosi 1,76 przypadku na 100 000 osób rocznie, a rozpowszechnienie 14,60 przypadków na 100 000 osób.45 Badania epidemiologiczne wskazują, że częstość występowania PBC waha się od 0,33 do 5,8 nowych przypadków na 100 000 mieszkańców rocznie, a wskaźniki rozpowszechnienia od 1,91 do 40,2 przypadków na 100 000 mieszkańców.678

Zachorowalność i rozpowszechnienie PBC różnią się znacząco w zależności od regionu geograficznego:45

  • Ameryka Północna: zachorowalność 2,75 na 100 000 osób; rozpowszechnienie 21,81 na 100 000 osób45
  • Europa: zachorowalność 1,86 na 100 000 osób; rozpowszechnienie 14,59 na 100 000 osób45
  • Region Azji i Pacyfiku: zachorowalność 0,84 na 100 000 osób; rozpowszechnienie 9,82 na 100 000 osób45

Najwyższe wskaźniki rozpowszechnienia PBC odnotowano w Wielkiej Brytanii, Skandynawii, Kanadzie i Stanach Zjednoczonych, czyli na półkuli północnej, podczas gdy najniższe wartości pochodzą z Australii.910 W niektórych badaniach z Wielkiej Brytanii wskaźnik rozpowszechnienia określono na poziomie 35 przypadków na 100 000 mieszkańców, przy rocznej zachorowalności wynoszącej 2-3 przypadki na 100 000 osób.1112

Zmiany w częstotliwości występowania na przestrzeni lat

Zachorowalność na PBC stale rosła do około 2000 roku na całym świecie. W Ameryce Północnej i Europie wskaźniki zachorowalności od tego czasu ustabilizowały się, podczas gdy w regionie Azji i Pacyfiku nadal powoli rosną, prawdopodobnie ze względu na poprawę w zgłaszaniu przypadków.13 Rozpowszechnienie PBC we wszystkich trzech regionach stale rośnie, choć w szybszym tempie w Ameryce Północnej niż w Europie.13

W Szwecji rozpowszechnienie PBC wzrosło znacząco z 5,0 (1987) do 34,6 (2014) na 100 000 mieszkańców, podczas gdy roczna zachorowalność utrzymywała się na stosunkowo stałym poziomie, z medianą 2,6 na 100 000 osobolat.1415 Podobnie w Holandii badanie populacyjne przeprowadzone w latach 2000-2008 wykazało wzrost zachorowalności i rozpowszechnienia PBC w czasie.16

W badaniu przeprowadzonym w latach 2004-2014 w Stanach Zjednoczonych, obejmującym dane z 3488 pacjentów otrzymujących rutynową opiekę kliniczną, rozpowszechnienie PBC wzrosło z 21,7 do 39,2 na 100 000 osób.17 Sugeruje to możliwy wzrost rozpowszechnienia PBC między 2004 a 2014 rokiem.

Dystrybucja demograficzna

PBC dotyka osoby obu płci, wszystkich ras i grup etnicznych, ale wykazuje wyraźną przewagę u kobiet.12 Wcześniejsze badania wskazywały na stosunek kobiet do mężczyzn wynoszący 10:1. Nowsze dane pokazują, że chociaż PBC pozostaje chorobą dominującą u kobiet, występuje również częściej u mężczyzn niż wcześniej sądzono, ze stosunkiem kobiet do mężczyzn bliższym 4-6:1.121819

U mężczyzn PBC często diagnozuje się w starszym wieku, gdy choroba jest bardziej zaawansowana.12 Mężczyźni z PBC mają wyższy wskaźnik progresji do marskości wątroby i raka wątrobowokomórkowego (HCC), są diagnozowani na późniejszym etapie i słabiej reagują na kwas ursodeoksycholowy (UDCA).1814

Zachorowalność i rozpowszechnienie PBC rosną wraz z wiekiem, z najwyższymi wartościami w przedziale wiekowym 60-79 lat.45 PBC najczęściej identyfikuje się u osób w średnim wieku (40-60 lat) i jest wyjątkowo rzadka poniżej 25 roku życia.45 Większość pacjentów otrzymuje diagnozę między 30 a 65 rokiem życia, najczęściej w wieku 40-50 lat.202122

U kobiet powyżej 45 roku życia rozpowszechnienie PBC może osiągnąć nawet 1 na 800.232412 W badaniu przeprowadzonym w Okinawie w Japonii PBC zdiagnozowano u 5,7% kobiet z bezobjawowym podwyższonym poziomem GGT podczas corocznych badań kontrolnych, co daje szacunkowe rozpowszechnienie PBC wynoszące 3400 na milion u kobiet powyżej 40 roku życia i 840 na milion w całej populacji.25

Czynniki genetyczne i środowiskowe

Istnieją przekonujące dowody na genetyczną predyspozycję do PBC. Częstość występowania PBC jest nawet 100 razy wyższa u krewnych pierwszego stopnia niż w populacji ogólnej.18 Wskaźnik względnego ryzyka dla rodzeństwa w przypadku PBC wynosi 10.26 Najwyższe ryzyko względne dla choroby rodzinnej wynosi 35 w przypadku córek matek z PBC.26

Badacze uważają, że czynniki genetyczne w połączeniu z określonymi czynnikami środowiskowymi wyzwalają rozwój PBC.27 W badaniu obejmującym ponad 1000 pacjentów zakażenia dróg moczowych, palenie tytoniu w przeszłości lub stosowanie hormonalnej terapii zastępczej były znacząco związane ze zwiększonym ryzykiem zachorowania na PBC.18

Adaptacyjna odporność wrodzona i warianty alleliczne w kompleksie głównego układu zgodności tkankowej (MHC) klasy II (D.R., D.Q.) są związane z podatnością na PBC.18 Obserwuje się również związek z większą częstością występowania PBC w szerokościach geograficznych bardziej oddalonych od równika, podobnie jak w przypadku stwardnienia rozsianego.24

Współwystępowanie chorób autoimmunologicznych

PBC jest silnie związana z innymi chorobami autoimmunologicznymi, w tym z zespołem Sjögrena, autoimmunologiczną chorobą tarczycy, zespołem CREST, twardziną i chorobą Raynauda.28 Badanie kohortowe wykazało, że 61,2% pacjentów z PBC ma współistniejącą chorobę autoimmunologiczną.28

W badaniu przeprowadzonym w ośrodku medycyny trzeciego stopnia zaobserwowano obecność pozawątrobowych chorób autoimmunologicznych u 40,8% przypadków, przy czym najwyższy wskaźnik występowania (46,4%) odnotowano u pacjentów z pierwotną chorobą dróg żółciowych.29

Pozawątrobowe manifestacje PBC są zazwyczaj autoimmunologiczne i występują u 32-63% pacjentów.30 Powszechnie wiadomo, że osoby z jedną chorobą autoimmunologiczną są bardziej narażone na rozwój innych chorób autoimmunologicznych.31

Nadzór i monitorowanie choroby pierwotnej dróg żółciowych

Skuteczny nadzór i monitorowanie są kluczowe w prowadzeniu pacjentów z PBC, ponieważ choroba ta może postępować i prowadzić do poważnych powikłań wątrobowych.32

Progresja choroby i rokowanie

Progresja choroby wątroby jest nieunikniona u większości nieleczonych osób, prowadząc do włóknienia i marskości wątroby w konsekwencji procesów zapalnych i cholestatycznych.32 Skumulowana częstość występowania poważnych nienowotworowych powikłań wątrobowych została określona na 15% po 15 latach obserwacji.32

Prawie połowa pacjentów z wczesnym stadium PBC przechodzi do bardziej zaawansowanego stadium w ciągu 5 lat.3334 Przejścia te są związane ze zwiększonym prawdopodobieństwem wystąpienia zdarzeń klinicznych, co podkreśla znaczenie nadzoru klinicznego u pacjentów z PBC we wczesnym stadium biochemicznym.3334

Bez leczenia 10-letnie przeżycie bezobjawowych pacjentów waha się od 50% do 70%, podczas gdy mediana przeżycia objawowych pacjentów wynosi od 5 do 8 lat.35 Nieleczona PBC ma średnie przeżycie 9-10 lat od momentu wystąpienia; około 25% pacjentów rozwija niewydolność wątroby w tym czasie.12

Czynniki ryzyka progresji

Zaawansowane włóknienie jest najważniejszym czynnikiem ryzyka rozwoju raka wątrobowokomórkowego (HCC), chociaż istnieją doniesienia o rozwoju HCC w PBC bez dowodów na zaawansowaną chorobę.36 Wśród chorób autoimmunologicznych PBC wydaje się być związana z największym ryzykiem HCC.36

Niezależne czynniki ryzyka gorszego rokowania obejmują wiek, powiększenie wątroby oraz zaawansowane włóknienie i marskość wątroby.12 U mężczyzn PBC częściej prowadzi do marskości wątroby i HCC, a choroba jest diagnozowana na późniejszym etapie.18

Protokoły nadzoru

Ze względu na wolne tempo uszkodzenia wątroby w PBC, nadzór nad progresją może obejmować biopsję wątroby, markery surowicze włóknienia lub nieinwazyjne badania, takie jak elastografia wątroby.35

Pacjenci z PBC i marskością wątroby powinni być agresywnie badani w kierunku raka wątrobowokomórkowego za pomocą dwukrotnego w ciągu roku badania przesiewowego wątroby.36 Obecnie wszystkie towarzystwa naukowe zalecają badania przesiewowe w kierunku HCC tylko w przypadku marskości wątroby. Marskość wątroby w PBC uzasadnia badania przesiewowe co 6 miesięcy ze względu na wysokie ryzyko związane z HCC.36

Aktualne wytyczne AASLD dotyczące PBC zalecają nadzór nad żylakami przełyku u pacjentów z liczbą płytek krwi ≤ 140 000/mm³ lub wynikiem ryzyka Mayo ≥ 4,1.37 Najlepszą szansą na przeżycie dla pacjentów z HCC jest przeszczep wątroby.36

Monitorowanie odpowiedzi na leczenie

Odpowiedź na kwas ursodeoksycholowy (UDCA) jest kluczowym wskaźnikiem prognostycznym. Pacjenci bez całkowitej odpowiedzi biochemicznej na UDCA nadal odnoszą korzyści z UDCA, co podkreśla jego znaczenie jako terapii pierwszego rzutu dla wszystkich pacjentów z PBC.7

W ostatnich latach położono nacisk na znalezienie optymalnych kryteriów definiowania osób reagujących i niereagujących na UDCA.38 Około 60-70% pacjentów odpowiada na obecne leczenie, co oznacza, że 30-40% pacjentów nie reaguje na UDCA i nadal istnieje potrzeba nowych strategii terapeutycznych.39

W pierwotnej chorobie dróg żółciowych odpowiedzi na leczenie można oceniać za pomocą kryteriów Paris-II.29 Wskaźnik nawrotów w jednym z badań określono na 48,5%.29

Współczesne wyniki leczenia

Wprowadzenie kwasu ursodeoksycholowego (UDCA) w leczeniu pacjentów z PBC zmieniło przebieg choroby, poprawiając wskaźniki przeżycia bez przeszczepu u nawet 60% pacjentów, zmniejszając tym samym śmiertelność.4041

Obecnie oczekiwana długość życia u pacjentów z PBC leczonych UDCA jest podobna jak u pacjentów bez PBC.41 Dzięki zwiększonej świadomości i wcześniejszemu rozpoznaniu, a także wprowadzeniu skutecznych metod leczenia, liczba przeszczepów wątroby z powodu PBC w Europie i Ameryce Północnej spada.28

PBC będzie nawracać u 20-40% pacjentów po przeszczepie.32 Częstość występowania PBC po przeszczepie jest wysoce zmienna w różnych badaniach (9-61%).32

Badania ze Szwecji nie wykazały znacząco zwiększonego ogólnego przeżycia od czasu wprowadzenia UDCA w szwedzkiej opiece zdrowotnej w 1998 roku.42 PBC ma znaczącą zachorowalność i śmiertelność, szczególnie z przyczyn związanych z wątrobą.42

Nadzór długoterminowy

Jednym z kluczowych aspektów życia z PBC jest dożywotni nadzór, w tym monitorowanie objawów lub biochemii wątroby, z uwzględnieniem odpowiedzi na UDCA i najbardziej odpowiedniej ścieżki opieki dla każdego pacjenta.43

Skuteczna strategia diagnostyki, zapobiegania i leczenia osteoporozy w PBC nie jest dobrze ustalona.44 Zapobieganie zmniejszeniu gęstości kości jest ważne, aby zmniejszyć ryzyko złamań i poprawić zachorowalność i śmiertelność.44

Występowanie osteoporozy w PBC waha się od 20% do 45%, przy czym najwyższe rozpowszechnienie obserwuje się u osób z marskością wątroby na liście oczekujących na przeszczep wątroby.45 Oczekuje się, że częstość występowania i rozpowszechnienie osteoporozy związanej z PBC wzrośnie wraz ze wzrostem rozpowszechnienia samej choroby.45

  • #1 Primary biliary cholangitis: Epidemiology, prognosis, and treatment
    https://pmc.ncbi.nlm.nih.gov/articles/PMC10241503/
    Primary biliary cholangitis (PBC) is a chronic cholestatic autoimmune liver disease characterized by a destructive, small duct, and lymphocytic cholangitis, and marked by the presence of antimitochondrial antibodies. The incidence and prevalence of PBC vary widely in different regions and time periods, and although disproportionally more common among White non-Hispanic females, contemporary data show a higher prevalence in males and racial minorities than previously described. […] PBC affects people of all sexes, races, and ethnicities. Earlier reports from case-finding studies showed a median female-to-male ratio of 10:1. Modern literature has demonstrated that, although PBC remains a female-predominant disease, it is also more prevalent in males than previously thought, with a female-to-male ratio closer to 46:1. PBC in males is often diagnosed at an older age, once the disease is more advanced.

    Primary biliary cholangitis (PBC) is a chronic cholestatic autoimmune liver disease characterized by a destructive, small duct, and lymphocytic cholangitis, and marked by the presence of antimitochondrial antibodies. The incidence and prevalence of PBC vary widely in different regions and time periods, and although disproportionally more common among White non-Hispanic females, contemporary data show a higher prevalence in males and racial minorities than previously described. […] Outcomes largely depend on early recognition of the disease and prompt institution of treatment, which, in turn, are directly influenced by provider bias and socioeconomic factors.

    The pooled global incidence and prevalence of PBC are estimated to be 1.76 and 14.60 per 100,000 persons, respectively. However, these estimates vary significantly according to the search strategy utilized, the size of the study population, and the degree of scrutiny of case finding. […] Contemporary data show that the incidence of PBC is higher in North America (2.75 per 100,000 persons) relative to Europe (1.86 per 100,000 persons) and lowest in the Asian-Pacific region (0.84 per 100,000 persons). The pooled prevalence follows a similar trend, being highest in North America (21.81/1000,000), Europe (14.59/100,000), and then in the Asian-Pacific region (9.82/100,000). […] The incidence and prevalence of PBC increase with age, with a peak range between 60 and 79 years old. PBC is typically identified in middle-aged individuals (40-60 years of age) and is exceptionally rare under 25 years of age.

  • #6 Primary biliary cholangitis – Wikipedia
    https://en.wikipedia.org/wiki/Primary_biliary_cholangitis
    PBC is a relatively rare disease, affecting up to one in 3,0004,000 people. […] PBC is more common in women, with a female:male ratio of at least 9:1. The peak incidence of PBC is in the fifth decade of life. […] Epidemiologic studies report heterogeneous incidence rates of 0.33 to 5.8 per 100,000 inhabitants per year, and prevalence rates of 1.9 to 40.2 per 100,000 inhabitants. Such figures, in particular the prevalence, have shown some increase in the last decades. […] The disease has been described worldwide, though North America and Northern Europe have shown the highest incidence and prevalence rates. […] First-degree relatives may have as much as a 500 times increase in prevalence. […] PBC is considered a prime example of the female preponderance in autoimmunity with a female to male ratio of up to 9:1, confirmed by large cohort studies.
  • #7 The disease
    https://www.globalpbc.com/the-disease
    Primary biliary cholangitis (PBC) – formerly known as primary biliary cirrhosis – is a chronic, slowly progressive autoimmune liver disease. PBC is a relatively rare disease and occurs worldwide. The incidence and prevalence in various countries and regions differ considerably and have been reported to vary from 0.33 to 5.8 and and 1.91 to 40.2 cases per 100 000 inhabitants, respectively. […] Patients without complete biochemical response to UDCA still benefit from UDCA, emphasizing its importance as first-line therapy for all patients with PBC.
  • #8
    https://www.xiahepublishing.com/2310-8819/JCTH-2019-00049
    It is estimated that the incidence of PBC ranges from 0.33 to 5.8 per 100,000 persons, with the reported point prevalence ranging from 1.91 to 33.8 per 100,000 persons, with large differences seen in geographic region. […] Both genetic and environmental factors contribute widely to the pathogenesis of PBC, with epidemiologic data indicating variable prevalence rates of disease into distinct and different geographical areas, or clusters. […] Europe and North America have the highest reported prevalence of PBC worldwide, as reflected in the increasing rate of PBC-related hospitalizations over the last 30 years. […] Despite these limitations, data support the observation that global rates of PBC are rising, as many countries continue to improve diagnostic accuracy, reporting measures, and surveillance of PBC patients. […] Heterogeneity in prevalence can in part be explained by regional variation in diagnostic awareness or access to care; however, several studies have suggested that environmental exposures may play a role in the development of specific regional clusters of PBC.

    https://ojrd.biomedcentral.com/articles/10.1186/1750-1172-3-1
    Primary biliary cirrhosis (PBC) is a chronic and slowly progressive cholestatic liver disease of autoimmune etiology characterized by injury of the intrahepatic bile ducts that may eventually lead to liver failure. Affected individuals are usually in their fifth to seventh decades of life at time of diagnosis, and 90% are women. Annual incidence is estimated between 0.7 and 49 cases per million-population and prevalence between 6.7 and 940 cases per million-population (depending on age and sex). […] PBC have a female predominance with an 8:1 female-to-male ratio. PBC affects individuals of all ethnic origin and accounts for 0.6~2.0% of deaths from cirrhosis worldwide. Its prevalence is estimated to be between 6.7 and 940 cases per million-population (the latter in women 40 yrs old in United Kingdom), while its incidence is estimated to be between 0.7 and 49 cases per million-population per year. […] The highest incidence and prevalence rates come from the United Kingdom, Scandinavia, Canada and the United States, all in the northern hemisphere, whereas the lowest is from Australia.

    Primary biliary cholangitis (PBC) is a chronic autoimmune cholestatic liver disease that predominantly affects women in early to middle age. […] The worldwide prevalence rate of PBC is estimated to be between 67 and 940 cases per million population and the incidence is between 0.7 and 49 cases per million population per year. […] The prevalence rates of PBC are high in UK, Scandinavia, Canada and USA. […] The associations between PBC and extrahepatic autoimmune diseases have been well established. More than 50% of patients with PBC have other autoimmune disease. […] The main aim in the management of PBC is to reverse injury from bile duct inflammation, improve the symptoms, slow down the disease progression, improve liver biochemistries, and prevent the long-term consequences of chronic cholestasis, such as pruritus, fatigue, osteoporosis and fat-soluble vitamin deficiencies.
  • #11 The British Society of Gastroenterology/UK-PBC primary biliary cholangitis treatment and management guidelines | Gut
    https://gut.bmj.com/content/67/9/1568
    Primary biliary cholangitis (formerly known as primary biliary cirrhosis, PBC) is an autoimmune liver disease in which a cycle of immune mediated biliary epithelial cell injury, cholestasis and progressive fibrosis can culminate over time in an end-stage biliary cirrhosis. […] PBC is most prevalent in women and those over the age of 50, but a spectrum of disease is recognised in adult patients globally; male sex, younger age at onset (45) and advanced disease at presentation are baseline predictors of poorer outcome. […] The epidemiology of PBC has been studied extensively. PBC meets the criteria for rare disease status (prevalence 50/100000) in all populations studied. […] Data from the largest UK study, in the north-east of England, suggest a prevalence of definite or probable disease of 35/100000, with an annual incidence of 23/100000.
  • #12 Primary biliary cholangitis: diagnosis and management – The Pharmaceutical Journal
    https://pharmaceutical-journal.com/article/ld/primary-biliary-cholangitis-diagnosis-and-management
    Primarily affecting women, primary biliary cholangitis is a progressive condition that can result in end-stage liver disease. […] A UK study involving 770 individuals with definite or probable PBC demonstrated a prevalence of 35 cases per 100,000 and an annual incidence of 2–3 cases per 100,000. Currently, there are an estimated 20,000 patients living with PBC in the UK. […] Women are predominantly affected by PBC; 9 out of 10 patients diagnosed are women and the prevalence can be as high as 1 in 800 in women aged over 45 years. […] Patients with PBC have a higher mortality rate than that of the general population. […] Left untreated, PBC carries an average survival of 9–10 years from presentation; around 25% of patients develop liver failure during this time. […] Independent risk factors for poorer prognosis include age, hepatomegaly, and advanced fibrosis and cirrhosis.

    The incidence of PBC steadily rose until the year 2000 across the globe. Growth rates in North America and Europe have since plateaued, whereas the incidence of PBC in the Asian-Pacific region has continued to increase slowly, likely due to improved case reporting. The prevalence of PBC in all three regions has risen steadily over time, although at a faster pace in North America relative to Europe.
  • #14 Incidence, prevalence, and outcome of primary biliary cholangitis in a nationwide Swedish population-based cohort | Scientific Reports

    Available epidemiological data on primary biliary cholangitis (PBC) in Sweden originate from regional studies in the 1980s and may not reflect modern day PBC. […] We aimed to estimate incidence and prevalence, survival and death causes, and gender differences in PBC. […] We identified 5,350 adults with PBC. Prevalence of PBC increased steadily from 5.0 (1987) to 34.6 (2014) per 100,000 inhabitants whereas the yearly incidence rate was relatively constant with a median of 2.6 per 100,000 person-years, with a female:male gender ratio of 4:1. […] In conclusion, we found that recorded prevalence of PBC in Sweden has increased substantially during the last 30 years although incidence has been stable. Patients diagnosed in young adulthood were at a 12.7-fold increased risk of death, and male PBC patients had worse prognosis.

    The PBC incidence rate was around 2.6 per 100,000 person-years with some variability that mainly can be explained by the start of different registers. […] There was a steady increase in the registered prevalence of PBC from 5.0 (1987) to 34.6 (2014) per 100,000 inhabitants. […] The female:male ratio in the whole study population was 4.0:1, with a higher proportion of women in the outpatient population 2001-2014. […] Patients with PBC were at increased risk of death. […] The major causes of death in PBC patients were digestive diseases related, most of them liver related. […] Patients with PBC compared to reference individuals had significantly more often a comorbidity diagnosis within all disease groups. […] UDCA was administered as the recommended first line treatment to 79.9% of PBC patients.

    In a more recent analysis of data from 3488 patients receiving routine clinical care in Fibrotic Liver Disease Consortium health systems, investigators found that, from 2004 to 2014, the prevalence of PBC increased from 21.7 to 39.2 per 100,000 persons. This data suggests a possible increase in the prevalence of PBC between 2004 and 2014. […] There is increasing evidence that PBC can be seen in most regions of the world. The previous lower inclusion of minorities in the clinical trials of PBC and lower rates in Asians may have been due to under reporting. In fact, recent data from Japan and China report that the prevalence of PBC is 55/100,000 adults and 49/100,000 adults, respectively.

    https://www.explorationpub.com/Journals/ei/Article/1003165
    Primary biliary cholangitis (PBC) is a rare orphan disease with a prevalence of 19 to 402 cases per million persons depending on the geographic location. Earlier studies suggested that women were mainly affected (90 to 95 percent), mostly between the ages of 30 to 65 years, commonly in their 40s or 50s, with the least reported age as young as 15 years and as old as 93 years in women. The incidence and prevalence of the disease increases with age. Newer studies suggest that the female-male ratio may be closer to 4:1. Male PBC patients have a higher rate of progression to cirrhosis and HCC, are diagnosed at a later stage, and respond less well to ursodeoxycholic acid (UDCA). […] Geographically, PBC is present throughout the world and in all races and ethnicities. It is more common in North America (Northern Midwest regions of the US) and Northern Europe. The disease burden is increasing over time, particularly in Asian populations, possibly due to better diagnostic tools rather than a true rising incidence. PBC prevalence is 100 times higher in first-degree relatives than in the general population and occurs in twins, indicating genetic susceptibility. In a study of over 1,000 patients, a history of urinary tract infections, past smoking, or use of hormone replacement therapies were also significantly associated with an increased risk of having PBC. […] Adaptive innate immunity and allelic variations in major histocompatibility complex (MHC) class II (D.R., D.Q.) are associated with susceptibility to PBC.

    Primary biliary cholangitis (PBC) is a rare chronic autoimmune-mediated cholestatic liver disease involving medium and small bile ducts that can lead to liver fibrosis and cirrhosis. […] According to statistics from the 2022 AsiaPacific Society for the Study of the Liver (APASL) guidelines and the latest meta-analysis, the estimated global incidence and prevalence of PBC are 17.6 and 146 per million, respectively, with North America being the highest, followed by Europe, and the lowest in the AsiaPacific region. Notably, all three regions showed an upward trend in the incidence and prevalence of PBC, with North America showing the fastest growth in prevalence. […] PBC is a disease in which female involvement is overwhelmingly dominant (the female-to-male incidence ratio is approximately 3.910:1); however, the incidence in male patients has been gradually increasing (female-to-male ratio (3.96.2:1) in recent years.

    Primary biliary cholangitis (PBC), formerly known as primary biliary cirrhosis, is a chronic disease of the liver, presumably autoimmune in nature, that leads to progressive cholestasis through intrahepatic bile duct destruction and often end-stage liver disease. The name change reflects the fact that cirrhosis occurs only in the late stage and therefore does not correctly identify patients with early-stage disease. […] PBC is most frequently a disease of women and occurs between the fourth and sixth decades of life. […] Although the epidemiology of primary biliary cholangitis has not been studied systematically, the published prevalence is 65.4 cases for women and 12.1 cases for men (40.2 cases overall) per 100,000 population. The incidence of the disease has been estimated as 4.5 cases for women and 0.7 cases for men (2.7 cases overall) per 100,000 population.

[…] Primary biliary cholangitis is more common in Northern Europeans and is less common in populations of African descent. […] Women account for 75-90% of patients with primary biliary cholangitis. Males who are affected have a disease course similar to that of females; however, men appear to be more likely to develop hepatocellular carcinoma. […] Primary biliary cholangitis mostly affects middle-aged women, with a mean age of 39 years. Onset usually occurs in persons aged 30-65 years.

    Primary biliary cholangitis (PBC) is a chronic intrahepatic cholestatic disease with not fully elucidated pathogenesis. PBC typically affects middle-aged women, commonly presents with fatigue and pruritus, or with an asymptomatic elevation of serum alkaline phosphatase (ALP)/glutamyl transpeptidase (GGT). The reported incidence and prevalence of PBC in the AsiaPacific region (8.4, and 98.2118.8 per million, respectively) were lower than that in North America (27.5 and 218.1 per million, respectively) and Europe (18.6 and 145.9 per million, respectively). Of note, the geographical differences in PBC epidemiology exist even within the AsiaPacific region, with a higher reported prevalence in Japan and China (191.18 per million) and a much lower reported prevalence in South Korea and Australia (39.09 per million). The prevalence of PBC in the AsiaPacific region has become higher than once deemed and increased quickly. A recent study in Japan demonstrated that the point prevalence of PBC was 338 per million, which was comparable to that in Europe and North America. Another Japanese study reported that PBC was diagnosed in 5.7% of the women with asymptomatic serum GGT elevation at the annual health check-up among a large population, yielding an estimated PBC prevalence of 3400 per million in women over 40 years old and 840 per million in the whole population in Okinawa Prefecture.

    Primary biliary cholangitis is an autoimmune disease in which the bile ducts are inflamed and slowly destroyed. It previously was called primary biliary cirrhosis. […] Although it affects both sexes, primary biliary cholangitis mostly affects women. […] Researchers think that genetic factors combined with certain environmental factors trigger primary biliary cholangitis. […] The following factors may increase your risk of primary biliary cholangitis: Most people with primary biliary cholangitis are women. It’s most likely to occur in people 30 to 60 years old. You’re more likely to get the condition if you have a family member who has or had it. It’s most common in people of northern European descent, but primary biliary cholangitis can affect all ethnicities and races. […] As liver damage worsens, primary biliary cholangitis can cause serious health problems, including liver scarring, called cirrhosis. Cirrhosis makes it difficult for your liver to work and may lead to liver failure.

    Primary biliary cholangitis (PBC) is an autoimmune liver disease characterized by progressive destruction of the intrahepatic bile ducts, leading to cholestasis. PBC is known to have both hepatic and extrahepatic manifestations. Extrahepatic manifestations are seen in up to 73% of patients with PBC, with the most common being Sjogrens syndrome, thyroid dysfunction and systemic sclerosis. […] A systematic review of population-based epidemiological studies reported that PBC incidence rates range from 0.9 to 5.8 per 100,000 inhabitants/year and prevalence rates range from 1.9 to 40.2 per 100,000 inhabitants/year. […] Given the high concordance rate among monozygotic twins and high level of PBC aggregates in families, there appears to be a genetic predisposition towards this disease.

[…] The authors wrote about the latest evidence related to the risks and outcomes of HCC in people with PBC. They said such cases warrant vigilance. […] Advanced fibrosis is the most important risk factor for the development of HCC, but there are other reports showing the development of HCC in PBC without evidence of advanced disease, the investigators wrote. […] Among autoimmune diseases, PBC appears to be associated with the greatest HCC risk. […] The best chance of survival for patients is liver transplant, they added. […] At present, the authors added, cirrhosis is the only indication for which all scientific societies recommend HCC screening. They said cirrhosis in PBC warrants screening every 6 months given the high risks associated with HCC, and they added that more studies are needed to better understand the ways in which treatment response for PBC might affect the risk of developing HCC.
