Zespół patau
Epidemiologia

Zespół Patau (trisomia 13) to rzadka aberracja chromosomowa o częstości występowania od 1 na 5000 do 1 na 16000 żywych urodzeń, z różnicami regionalnymi (np. 1,9 na 10000 urodzeń w Europie, 1 na 3000 ciąż w Australii). Głównym czynnikiem ryzyka jest zaawansowany wiek matki (średnio 32 lata). Większość przypadków wynika z nondysjunkcji, choć translokacyjna trisomia 13 może być dziedziczona. Śmiertelność jest bardzo wysoka: ponad 95% płodów umiera wewnątrzmacicznie, a mediana przeżycia noworodków wynosi 2,5-10 dni. Wskaźniki śmiertelności to 48% w pierwszym tygodniu życia, 82% w pierwszym miesiącu i 87-90% w pierwszym roku. Najczęstsze przyczyny zgonów to zatrzymanie krążenia i oddychania (69%), wrodzone wady serca (13%) oraz zapalenie płuc (4%).

Epidemiologia zespołu Patau

Zespół Patau (trisomia 13) jest rzadką aberracją chromosomową, występującą z częstością od 1 na 5000 do 1 na 16000 żywych urodzeń, w zależności od badanej populacji123. W niektórych opracowaniach podaje się częstość występowania wynoszącą 1 na 8000-12000 żywych urodzeń45. Badanie przeprowadzone przez Springett i wsp. w 25 rejestrach populacyjnych w 16 krajach europejskich wykazało częstość występowania trisomii 13 na poziomie 1,9 na 10000 wszystkich urodzeń4.

W Wielkiej Brytanii częstość występowania szacuje się na około 2 przypadki na 10000 urodzeń67, natomiast w stanie Minnesota w latach 2014-2018 wykryto 13 przypadków zespołu Patau, co daje częstość 1 na 10000 urodzeń2. W Australii (stan Wiktoria) częstość występowania oszacowano na 1 na 3000 ciąż8.

Zespół Patau jest uważany za trzecią najczęstszą trisomię autosomów9, choć jednocześnie jest najrzadszą i najcięższą formą spośród trisomii umożliwiających przeżycie do urodzenia1011. Jest to znacznie rzadsza wada niż zespół Downa, który występuje z częstością około 1 na 700 urodzeń1.

Czynniki ryzyka

Głównym czynnikiem ryzyka wystąpienia zespołu Patau jest zaawansowany wiek matki10412. Jest to zależność charakterystyczna dla wszystkich trisomii autosomów u płodów, które przeżywają do terminu porodu4. Średni wiek matki w momencie urodzenia dziecka z zespołem Patau wynosi 32 lata1314.

Większość przypadków trisomii 13 nie jest dziedziczna i wynika z losowych zdarzeń podczas formowania komórek jajowych i plemników u zdrowych rodziców23. Błąd w podziale komórkowym zwany nondysjunkcją prowadzi do powstania komórki rozrodczej z nieprawidłową liczbą chromosomów3. Jednakże, translokacyjna trisomia 13 może być dziedziczona – osoba niezaburzona może być nosicielem przegrupowania materiału genetycznego między chromosomem 13 a innym chromosomem3.

Ryzyko ponownego wystąpienia zespołu Patau w kolejnych ciążach wynosi około 1%213, ale może się różnić w zależności od szczegółów nieprawidłowości chromosomowej i wieku matki15.

Różnice płciowe

Niektóre badania wskazują, że zespół Patau występuje częściej u płci żeńskiej niż męskiej1617. Wielostanowe badanie populacyjne przeprowadzone przez Meyer i wsp. wykazało, że najniższe wskaźniki śmiertelności występowały wśród dziewczynek oraz potomstwa matek rasy czarnej (nie-latynoskiego pochodzenia)4.

Przeżywalność i rokowanie

Rokowanie w zespole Patau jest bardzo poważne. Większość płodów z trisomią 13 umiera wewnątrzmacicznie, a śmierć płodu występuje w ponad 95% przypadków18. Wśród żywo urodzonych dzieci, mediana przeżycia wynosi od 2,5 do 10 dni4115.

Dane dotyczące przeżywalności wskazują, że:

  • 48% noworodków z zespołem Patau umiera w pierwszym tygodniu życia, z czego połowa w pierwszym dniu19
  • 82% umiera w ciągu pierwszego miesiąca15
  • 87-90% dzieci nie przeżywa pierwszego roku życia119
  • 95% umiera w ciągu pierwszych 6 miesięcy15

Badanie przeprowadzone w Europie Zachodniej przez Glinianaia i wsp. oszacowało, że wśród dzieci z trisomią 13 wskaźniki przeżycia wynoszą 34% po 4 tygodniach, 17% po roku i 11% po 10 latach20. Inne badanie wskazuje, że około 13% dzieci z zespołem Patau przeżywa do 10 roku życia16.

Najczęstszymi przyczynami śmierci u pacjentów z zespołem Patau są: zatrzymanie krążenia i oddychania (69%), wrodzone wady serca (13%) oraz zapalenie płuc (4%)20. Osoby, które przeżyją okres noworodkowy, przebywają średnio 10,8 dni na oddziale intensywnej terapii neonatologicznej20.

Chociaż większość przypadków kończy się zgonem w pierwszym roku życia, istnieją doniesienia o dłuższym przeżyciu przy zastosowaniu intensywnych interwencji medycznych1. Dzieci z formą mozaikową lub translokacyjną trisomii 13 mają zazwyczaj lepsze rokowanie21. Bardzo rzadko pacjenci mogą dożyć wieku nastoletniego lub dorosłego2223.

Nadzór i monitorowanie epidemiologiczne

Badania przesiewowe

Badania przesiewowe w kierunku zespołu Patau są oferowane wszystkim kobietom w ciąży jako część rutynowej opieki prenatalnej1224. Obejmują one:

  • Połączony test przesiewowy (tzw. test podwójny) wykonywany między 10. a 14. tygodniem ciąży1225
  • Nieinwazyjne badanie prenatalne (NIPT) – oferowane w przypadku podwyższonego ryzyka w teście połączonym1225
  • Test poczwórny (quadruple test) – oferowany między 14. a 20. tygodniem ciąży, jeśli pacjentka zgłosi się zbyt późno na test połączony24
  • Badanie ultrasonograficzne w 20. tygodniu ciąży25

Jeśli wynik testu przesiewowego wskazuje na podwyższone ryzyko (większe lub równe 1:150), proponowane są dalsze badania diagnostyczne2425.

Badania diagnostyczne

Zespół Patau może być zdiagnozowany przed urodzeniem za pomocą następujących metod1226:

  • Amniocenteza – badanie płynu owodniowego z analizą chromosomów komórek płodu265
  • Biopsja kosmówki (CVS) – pobieranie próbek łożyska2728
  • Badanie FISH (fluorescencyjna hybrydyzacja in situ) – do wykrywania wad chromosomowych29

Po urodzeniu diagnoza jest potwierdzana poprzez badanie kariotypu, które analizuje chromosomy z próbki krwi dziecka3031. Dodatkowo wykonywane są badania obrazowe, takie jak tomografia komputerowa (CT), rezonans magnetyczny (MRI) oraz echokardiografia, w celu oceny wad mózgu, serca i nerek32.

Rejestry i systemy nadzoru

W wielu krajach istnieją systemy rejestracji i nadzoru epidemiologicznego przypadków zespołu Patau:

  • W Wielkiej Brytanii informacje o dzieciach z zespołem Patau są przekazywane do National Congenital Anomaly and Rare Disease Registration Service (NCARDRS)12
  • W Szkocji funkcjonuje rejestr CARDRISS (Congenital and Rare Condition Register), prowadzony przez Public Health Scotland6
  • W Walii informacje są przekazywane do Congenital Anomaly Register and Information Service (CARIS)33
  • W stanie Minnesota od 2005 roku prowadzony jest monitoring zespołu Patau wśród żywych urodzeń w wybranych hrabstwach2
  • Na Florydzie funkcjonuje system śledzenia wad wrodzonych, będący częścią krajowego systemu zbierania danych o występowaniu i czynnikach ryzyka wad wrodzonych34

Dane z tych rejestrów służą do planowania i poprawy usług zdrowotnych, opieki i innych usług publicznych6. Identyfikacja dzieci urodzonych z wadami wrodzonymi i gromadzenie informacji na ich temat jest pierwszym krokiem w zapobieganiu wadom wrodzonym34.

Wpływ na ciążę i matkę

Badanie retrospektywne kohortowe przeprowadzone przez Dotters-Katz i wsp. wykazało, że ryzyko pewnych chorób jest wyższe u kobiet z ciążą z trisomią 13 niż u kobiet z ciążą bez trisomii 13. Prawdopodobieństwo wystąpienia nadciśnienia indukowanego ciążą (GHD) jest 6,3 razy większe, a ryzyko stanu przedrzucawkowego z ciężkimi objawami jest 12,5 razy wyższe20.

Anomalie chromosomowe są obecne w 50% zgonów płodów przed 20. tygodniem ciąży i występują w 6-13% przypadków martwych urodzeń. Ogólnie, śmierć płodu występuje w 15% ciąż rozpoznanych klinicznie121.

Dane demograficzne i geograficzne

Nie zaobserwowano istotnych różnic rasowych lub geograficznych w częstości występowania zespołu Patau417. Choroba dotyka osoby wszystkich grup etnicznych32.

Dostępne dane z różnych regionów świata pokazują pewne zróżnicowanie w częstości występowania zespołu Patau:

Region/Kraj Częstość występowania Źródło
Europa (16 krajów) 1,9 na 10 000 urodzeń 4
Wielka Brytania 2 na 10 000 urodzeń 6
Minnesota, USA 1 na 10 000 urodzeń 2
Australia (Victoria) 1 na 3 000 ciąż 8
RPA 1 na 24 000 urodzeń 28
Ogólnoświatowo 1 na 5 000 do 1 na 16 000 urodzeń 12

W Anglii i Walii w latach 2008-2009 odnotowano 172 diagnozy zespołu Patau, z czego 91% zostało zdiagnozowanych prenatalnie. Około 4% przypadków zespołu Patau o nieznanym wyniku prawdopodobnie kończy się żywym urodzeniem, dlatego całkowitą liczbę żywych urodzeń szacuje się na 1835.

Trendy i prognozy

Częstość występowania zespołu Patau zmniejsza się w wyniku badań przesiewowych prenatalnych w kierunku wrodzonych wad rozwojowych36. Szeroko dostępne badania prenatalne umożliwiają wcześniejsze wykrywanie tej wady i podejmowanie świadomych decyzji dotyczących dalszego postępowania z ciążą.

Według IMARC Group, rynek związany z zespołem Patau rozwija się ze względu na rosnącą liczbę ciąż w zaawansowanym wieku matki, co jest ustalonym czynnikiem ryzyka zaburzeń chromosomowych29. Zwiększająca się częstość występowania zespołu Patau oraz wzrost liczby badań i działań rozwojowych napędzają wzrost rynku zespołu Patau37.

Badania nad czynnikami związanymi z wydłużonym przeżyciem są ważne dla prognozowania rokowania i doradztwa rodzinom, które mają niemowlęta z rozpoznaniem trisomii 1338. Istnieją doniesienia o przypadkach dłuższego przeżycia, w szczególności u pacjentów z mozaikową formą trisomii 1338.

Znaczenie dla zdrowia publicznego

Ze względu na ciężki przebieg i krótkie przeżycie intensywna opieka w zespole Patau jest kontrowersyjna39. Nie istnieje specyficzne leczenie ani lek na trisomię 13, a interwencje medyczne są skupione na łagodzeniu objawów4041.

Leczenie chirurgiczne wad rozwojowych niewiele poprawia złe rokowanie związane z tym zespołem18. Zapobieganie poprzez rutynowe badania ultrasonograficzne matki i prenatalne badania CVS lub amniocentezę w przypadkach wysokiego ryzyka może ograniczyć istniejące obciążenie chorobą w perspektywie długoterminowej36.

Ważne jest, aby rodzice dzieci z zespołem Patau otrzymywali wsparcie, informacje, wiedzę i opcje umożliwiające podjęcie decyzji najlepszej dla ich dziecka27. Rodzice dziecka z trisomią 13 spowodowaną translokacją powinni przejść badania genetyczne i poradnictwo, co może pomóc im w zrozumieniu szans na posiadanie kolejnego dziecka z tym schorzeniem2642.

Diagnoza zespołu Patau jest dopiero początkiem trudnej drogi dla każdej rodziny41. Ze względu na złożony charakter trisomii 13, niemowlęta często stają przed wyzwaniami medycznymi podczas porodu i w okresie noworodkowym41. Konieczne jest odpowiednie poradnictwo i wsparcie dla rodzin, które doświadczają tej choroby.

    Cytogenetic abnormalities are present in 50% of fetal deaths before 20 weeks gestational age and are present in 6% to 13% of stillbirths. Overall, fetal death occurs in 15% of pregnancies that are recognized clinically. Trisomy 13 is one of the more common trisomies and occurs in 1 per 5000 total births. This frequency is less common than Down syndrome, which occurs in 1 per 700 total births. The incidence of Edwards syndrome is similar, occurring in about 1 per 5000 live births. […] Multiple large studies have detailed the overall poor prognosis of patients with Patau syndrome. Historically, median survival is 7 to 10 days in live-born patients, and 90% do not survive to 1 year. Recently, reported cases of longer duration survival have come to light with the use of aggressive medical interventions. […] Ninety percent of patients with Patau syndrome do not survive until one year after birth, and many die in utero.

  • #3 Trisomy 13: MedlinePlus GeneticsLock
    https://medlineplus.gov/genetics/condition/trisomy-13/
    Trisomy 13 occurs in about 1 in 16,000 newborns. Although women of any age can have a child with trisomy 13, the chance of having a child with this condition increases as a woman gets older. […] Only five percent to 10 percent of children with this condition live past their first year. […] Most cases of trisomy 13 are not inherited and result from random events during the formation of eggs and sperm in healthy parents. An error in cell division called nondisjunction results in a reproductive cell with an abnormal number of chromosomes. […] Translocation trisomy 13 can be inherited. An unaffected person can carry a rearrangement of genetic material between chromosome 13 and another chromosome.

Historically, those who are live-born with this syndrome usually survive for a median of 7 to 10 days, and 90% do not live past their first year. […] However, recent case studies have shown that aggressive medical treatment can lead to greater survival durations. Patau syndrome has different forms and those with the mosaic type or the unbalanced translocations type generally have a better prognosis. […] Even with the most aggressive management, the average life span for patients with Patau syndrome tends to be about two years. […] Most individuals with Patau syndrome, about 90%, unfortunately, do not live past their first year after birth, and many do not survive even until birth.

    Trisomy 13 (Patau syndrome) is a well-recognised, multiple congenital anomaly syndrome, characterised by the cardinal triad of orofacial clefts, microphthalmia and postaxial polydactyly of the limbs. With an estimated worldwide live-born prevalence (after the advent of prenatal diagnosis) of 1/10 000, it is an important cause of aneuploidy. […] Studies conducted in South Africa (SA) many years ago estimated the prevalence of Patau syndrome at 1/24 000. […] Given that ~4% of birth defects in SA are formally reported, it is likely that prevalence figures are actually much higher. […] Pre- and postnatal diagnosis of Trisomy 13 in SA is often made on PCR aneuploidy screen, which detects triplicate copies of short tandem repeat sequences on chromosome 13. […] Trisomy 13 can be suspected on antenatal US by 20 weeks’ gestation in 90 – 100% of cases. […] Invasive prenatal testing, including CVS (11 – 13 weeks’ gestation) or amniocentesis (16 – 20 weeks’ gestation), can be offered to women of advanced maternal age who are at increased risk of aneuploidy or those whose antenatal US has detected fetal anomalies.

    Patau syndrome is a less common genetic condition brought about by trisomy 13. The condition occurs as a result of an additional copy of chromosome 13, resulting in critical developmental abnormalities, such as congenital heart abnormalities, brain defects, cleft lip/palate, polydactyly, and numerous organ malformations. […] The diagnosis of Patau syndrome is mainly by prenatal screening, e.g., non-invasive prenatal testing (NIPT), maternal serum screening, or ultrasound scanning, to identify structural defects. Confirmation is done by karyotyping or fluorescence in situ hybridization (FISH) to detect chromosomal defects. […] The increasing rate of advanced maternal age pregnancies, which is an established risk factor for chromosomal disorders, is one of the main drivers in the Patau syndrome market.

    Patau syndrome is a rare and one of the most severe forms of autosomal trisomies. Having a karyotype of trisomy 13, it is associated with high rate of pregnancy loss and poor infant survival rate. The incidence is 1 in 20,000 live births. […] Although the incidence has been reported as 1 in 20,000 live births, the rate is decreasing as a result of prenatal screening for congenital birth defects. More than 90% of the infants die in the first month after birth and approximately 1 % live beyond one year. […] The life expectancy of the infants with trisomy 13 is very low and the evolution is correlated with several factors, including the severity of cardiac and cerebral malformations and of other multiple congenital anomalies. […] Trisomy 13 is a rare genetic disorder and there is no specific treatment or cure for it. Though references citing a better prognosis with use of intensive care including resuscitation and surgical procedures are available, prevention using routine maternal ultrasound and prenatal Chorionic villi sampling (CVS) or amniocentesis in high risk cases can circumvent the existing disease burden in long term. Recurrence risk further should be addressed in confirmed cases by detailed cytogenetic analysis and genetic counseling.
