Progeria
Rokowania, prognozy i postęp choroby

Progeria (Zespół Hutchinsona-Gilforda, HGPS) to ultrarzadki, śmiertelny zespół przedwczesnego starzenia się o podłożu mutacji w genie LMNA, prowadzący do produkcji nieprawidłowego białka – progeryny. Fenotyp kliniczny obejmuje m.in. niski wzrost, mikrognację, łysienie, zmiany pigmentacji skóry oraz mikrocefalię. Średnia długość życia bez leczenia wynosi około 14,5 lat, z głównymi przyczynami zgonów związanymi z powikłaniami miażdżycy, takimi jak zawał mięśnia sercowego, niewydolność serca i udar mózgu. Diagnostyka opiera się na ocenie fenotypu klinicznego oraz molekularnym potwierdzeniu mutacji w genie LMNA, a także panelach genetycznych obejmujących 82 geny związane z zespołami progeroidalnymi, które pozwalają na rozpoznanie molekularne w około 26% przypadków, szczególnie przy silnym klinicznym podejrzeniu zespołu progeroidalnego.

Progeria – wprowadzenie

Progeria (Zespół Hutchinsona-Gilforda, HGPS) to ultrarzadki, śmiertelny zespół przedwczesnego starzenia się o charakterze segmentowym, wywołany nieprawidłowym białkiem laminą A, zwanym progeryną. Progeria charakteryzuje się plejotropowymi fenotypami związanymi z normalnym starzeniem się i należy do heterogennej grupy rzadkich i złożonych zespołów dziedzicznych zwanych zaburzeniami progeroidalnymi. Dzieci z progerią zazwyczaj wyglądają zdrowo przy urodzeniu, jednak z czasem rozwijają charakterystyczne objawy przedwczesnego starzenia.1234

Prognoza przeżycia w progerii

Progeria jest zawsze śmiertelna, a średnia długość życia osób z klasyczną postacią zespołu Hutchinsona-Gilforda (HGPS) wynosi około 14,5 lat. Niektóre dzieci umierają już w wieku 6 lat, podczas gdy niektórzy dorośli z progerią dożywają wczesnych lat 20. W badaniu obejmującym 258 osób z tym schorzeniem średni wiek w momencie śmierci wynosił 14,6 lat, a najstarszy pacjent w tym badaniu zmarł przed ukończeniem 28 lat.567

Co ciekawe, w Japonii odnotowano przypadek osoby z HGPS (mutacja LMNA), która przeżyła 45 lat, co stanowi wyjątek od typowego przebiegu choroby. Wraz z wprowadzeniem leczenia farmakologicznego, średnia długość życia pacjentów z progerią wzrosła – przy zastosowaniu terapii lonafarnibu średnia ta zwiększa się do prawie 20 lat.89

Główne przyczyny zgonu

Najczęstszymi przyczynami śmierci u pacjentów z HGPS są powikłania związane z miażdżycą, w tym:

Postępy w diagnostyce progerii

Diagnoza progerii i innych zespołów progeroidalnych opiera się głównie na fenotypie klinicznym. Ostatnie badania dostarczyły narzędzi do oceny prawdopodobieństwa, czy dany zespół lub pacjent ma charakter progeroidalny. Jest to znaczący krok naprzód w zrozumieniu, co stanowi zaburzenie przedwczesnego starzenia się i jak je diagnozować.1415

Fenotypy o najwyższej częstości występowania w zespołach progeroidalnych obejmują: niski wzrost, mikrognację, wrażliwość na słońce, łysienie, zmiany pigmentacji skóry, mikrocefalię i nowotwory. Porównywanie fenotypów zespołów z fenomem progeroidalnym przy użyciu klastrowania hierarchicznego, sieci i średniej częstości występowania jest użytecznym i wiarygodnym narzędziem do potencjalnej identyfikacji nowych zespołów progeroidalnych.16171819

Molekularne metody diagnostyczne

Sekwencjonowanie wysokoprzepustowe z wykorzystaniem panelu genów związanych z laminopatiami i zaburzeniami przedwczesnego starzenia się umożliwiło diagnozę molekularną rzadkich zaburzeń związanych z cechami przedwczesnego starzenia się i poradnictwo genetyczne dla rodzin. Stanowi to interesującą analizę pierwszego poziomu, zanim sekwencjonowanie całego genomu zostanie zaproponowane jako przyszły drugi krok w rodzinach bez diagnozy molekularnej.20

W badaniu obejmującym 66 pacjentów z użyciem panelu 82 genów związanych z zespołami przedwczesnego starzenia, rozpoznanie molekularne zostało ustalone lub potwierdzone w około 26% przypadków (około 1/4 kohorty). Skuteczność diagnostyczna w dużej mierze zależała od siły klinicznego podejrzenia – gdy istniało wyraźne podejrzenie nosologicznie zdefiniowanego zespołu progeroidalnego, rozwiązano prawie 40% przypadków.2122

Postępy w terapii progerii

Obecnie nie istnieje lekarstwo na progerię, a dostępne leczenie nie zatrzymuje postępu choroby. Niemniej jednak, prowadzone są obiecujące badania i terapie, które mogą poprawić jakość życia i wydłużyć przeżycie pacjentów.23

Leczenie lonafarniebem

Leczenie lekiem lonafarnib (inhibitor transferazy farnezylowej) pokazało obiecujące wyniki i wydłużyło życie osób z progerią. Badania wykazały, że lonafarnib przedłuża życie osób z progerią średnio o 4,5 roku, co stanowi znaczący postęp w terapii tej rzadkiej choroby.2425

Badania kliniczne z wykorzystaniem lonafarnibu doprowadziły do zwiększenia masy ciała i gęstości kości oraz lepszego funkcjonowania serca u pacjentów z progerią. Dzieci uczestniczą obecnie w nowym badaniu, rozpoczętym w kwietniu, które będzie badać 10 kandydatów z dwóch krajów, aby zmierzyć efekty leczenia u dzieci, zmiany we wzorcach zdrowotnych i wskaźniki przeżycia.26

Potencjalne biomarkery

Pierwsze badania z zastosowaniem platformy wieloanalizy u pacjentów z HGPS zidentyfikowały zestaw białek osoczowych u dzieci z progerią, przed i rok po rozpoczęciu leczenia inhibitorem transferazy farnezylowej lonafarniebem. Jest to początkowy krok w identyfikacji biomarkerów serologicznych, które mogą dostarczyć wglądu w naturalną historię choroby i/lub wskazywać na poprawę wraz z leczeniem.2728

Edycja genów jako potencjalna terapia

Obiecujące wyniki przyniosły badania nad edycją genów w modelach mysich. Pojedyncze wstrzyknięcie AAV9 wyrażającego edytor zasad adeninowych (ABE) w 14. dniu po urodzeniu poprawiło żywotność i znacznie wydłużyło medianę przeżycia myszy z 215 do 510 dni. Odkrycia te demonstrują potencjał edycji genów in vivo jako możliwego leczenia HGPS i innych chorób genetycznych poprzez bezpośrednie korygowanie ich pierwotnej przyczyny.29

Globalne inicjatywy w progerii

Fundacja Badań nad Progerią (PRF) prowadzi kampanię „Find the Other 150”, której celem jest globalne poszukiwanie niezdiagnozowanych dzieci z progerią, aby zapewnić im dostęp do niezbędnej opieki i pomóc w rozwoju badań klinicznych.30

Szacuje się, że w samych Indiach może mieszkać około 66 dzieci z klasyczną postacią progerii. Wczesna identyfikacja przypadków jest kluczowa – obserwuje się, że diagnoza często następuje dopiero po ukończeniu przez dziecko 4 lat. Szybsza identyfikacja poprzez lepszą znajomość objawów i unikanie błędnej diagnozy może prowadzić do poprawy jakości życia dzieci dotkniętych progerią.31

Przyszłość leczenia i diagnozy

W nadchodzących latach zwiększona świadomość na temat unikalnej histologii choroby i wprowadzenie nowych terapii powinny znacząco poprawić życie osób dotkniętych tą rzadką chorobą. Zdefiniowanie fenomu progerii optymalizuje diagnozę kliniczną pacjentów prezentujących różnorodne fenotypy i pozwoliło na opracowanie maszyny wektorów nośnych, która może przewidzieć prawdopodobieństwo, że zespół ma charakter progeroidalny, wyłącznie na podstawie fenotypów.3233

Chociaż progeria pozostaje nieuleczalna, dostępne opcje terapeutyczne, takie jak leki, zmiany w stylu życia i diecie oraz terapia zajęciowa, mogą złagodzić lub opóźnić niektóre objawy. Leczenie zależy również od stanu dziecka i objawów.34

Podsumowanie prognozy w progerii

Progeria jest chorobą śmiertelną, z przewidywanym średnim wiekiem przeżycia wynoszącym około 14,5 lat bez leczenia. Przy zastosowaniu nowoczesnych terapii, szczególnie lonafarnibu, średnia ta wzrasta do około 20 lat. Główną przyczyną śmierci pozostają powikłania sercowo-naczyniowe, w tym niewydolność serca, udar mózgu i zawał mięśnia sercowego.353637

Pomimo niepomyślnego rokowania, postępy w diagnostyce molekularnej, identyfikacji biomarkerów i obiecujące wyniki badań nad edycją genów stwarzają nadzieję na poprawę jakości życia i dalsze wydłużenie przeżycia pacjentów z tym rzadkim, genetycznym zaburzeniem w przyszłości.3839

    HutchinsonGilford progeria syndrome (HGPS) is an ultra-rare, fatal, segmental premature aging syndrome caused by the aberrant lamin A protein, progerin. […] This is the first study to employ a multi-analyte array platform in HGPS. Novel potential biomarkers identified in this study should be further validated by correlations with clinical disease status, especially proteins associated with cardiovascular disease and those that normalized with lonafarnib therapy. […] To date, no validated FDA-approved circulatory biomarker exists for HGPS. We have identified a set of plasma proteins in children with HGPS, before and 1 year after initiating treatment with the farnesyltransferase inhibitor lonafarnib. This is an initial survey step in identifying serologic biomarkers that may provide insight into the natural history of disease, and/or be indicative of improvements with treatment.

[…] Right from the first medical trial that resulted in increased weight and bone density and better heart functions in Progeria patients, the children are now participating in a new trial, started in April, which will study 10 candidates from two countries to measure effects of treatment on children, changes in health pattern and their survival rate, which is restricted to 15-17 years at the moment. […] What we need is faster identification. Until now, we have noticed we have been able to reach to the child only after he or she is four years old. If the physicians or paediatricians read the symptoms and avoid misdiagnosis, it can lead to better quality of life of Progeria-affected children, said Chindarkar. […] Our Find the Other 150 campaign is designed to do exactly that: search globally for the undiagnosed children with Progeria so that they too can have access to the unique care they need, and help advance clinical science for Progeria, said Fink.

    HutchinsonGilford progeria syndrome (HGPS) is an ultra-rare, fatal, segmental premature aging syndrome caused by the aberrant lamin A protein, progerin. […] This is the first study to employ a multi-analyte array platform in HGPS. Novel potential biomarkers identified in this study should be further validated by correlations with clinical disease status, especially proteins associated with cardiovascular disease and those that normalized with lonafarnib therapy. […] To date, no validated FDA-approved circulatory biomarker exists for HGPS. We have identified a set of plasma proteins in children with HGPS, before and 1 year after initiating treatment with the farnesyltransferase inhibitor lonafarnib. This is an initial survey step in identifying serologic biomarkers that may provide insight into the natural history of disease, and/or be indicative of improvements with treatment.

    This implies that such an approach may have significant potential for identifying meaningful plasma protein biomarkers for children with HGPS. Future studies should focus on essential studies that will further evaluate plasma proteins identified here as having abnormal levels in HGPS, namely validation and clinical disease correlations.
  • #29 In vivo base editing rescues Hutchinson-Gilford progeria syndrome in mice. – Document – Gale OneFile: Health and Medicine

    Hutchinson-Gilford progeria syndrome (HGPS or progeria) is typically caused by a dominant-negative C*G-to-T*A mutation (c.1824 C T; p.G608G) in LMNA, the gene that encodes nuclear lamin A. This mutation causes RNA mis-splicing that produces progerin, a toxic protein that induces rapid ageing and shortens the lifespan of children with progeria to approximately 14 years. […] A single injection of ABE-expressing AAV9 at postnatal day 14 improved vitality and greatly extended the median lifespan of the mice from 215 to 510 days. These findings demonstrate the potential of in vivo base editing as a possible treatment for HGPS and other genetic diseases by directly correcting their root cause. In a mouse model of progeria, an adenine base editor delivered with adeno-associated virus corrects the pathogenic mutation in LMNA, rescues vascular pathology and markedly extends the lifespan of the mice.

    https://www.delveinsight.com/blog/progeria-causes-symptoms-risk-factors-and-treatment-options
    The average life expectancy for a person affected with progeria (HGPS) is around 13.5 years. Some children with HGPS may die at a very young age, while some cases have been reported where the affected person has survived till the age of 20. Interestingly enough, in Japan, a person with HGPS (LMNA mutation) managed to survive for 45-years. Heart failure/Atherosclerosis (cardiovascular disease), Stroke, Myocardial Infarction are some of the major reasons for death. […] Progeria is not curable; however, the treatment option eases or delays some of the signs and symptoms. Specific therapies for individuals with HGPS are symptomatic and supportive. Medication, changes in diet lifestyle, and physical occupational therapy are the most common treatment options. The treatments also depend on the child’s condition and symptoms. […] In the coming years, increased awareness about the disease’s unique histology and the launch of emerging therapies are expected to significantly improve the lives of people affected by this rare disease.

    As progeroid syndromes have historically been diagnosed and described based solely on phenotypes, comparing syndromes phenotypes to the progeroid phenome using hierarchical clusterings, networks and mean prevalence is a useful and reliable tool for the potential identification of new progeroid syndromes. […] Additionally, defining the progeria phenome optimizes clinical diagnosis of patients presenting with a variety of phenotypes and has allowed us to develop a support vector machine that can predict a syndromes likelihood of being progeroid solely based on phenotypes.
