Bezdech senny
Rokowania, prognozy i postęp choroby

Obturacyjny bezdech senny (OBS) dotyka około 4% mężczyzn i 2% kobiet globalnie, stanowiąc istotny czynnik ryzyka chorób kardiometabolicznych oraz zwiększonej śmiertelności sercowo-naczyniowej, zwłaszcza przy ciężkim przebiegu (AHI ≥ 30). Terapia CPAP poprawia krótkoterminowo objawy takie jak senność dzienna i chrapanie, jednak jej wpływ na długoterminowe zapobieganie powikłaniom sercowo-naczyniowym pozostaje niepotwierdzony w randomizowanych badaniach. Wysoka heterogeniczność OBS wymaga spersonalizowanego podejścia diagnostycznego i terapeutycznego, a modele predykcyjne oparte na sztucznej inteligencji (AUC=0,976; 95% CI: 0,962-0,990) wykazują przewagę nad tradycyjnymi kwestionariuszami (SBQ, NoSAS) w identyfikacji pacjentów z umiarkowanym do ciężkim OBS. Hipoksja nocna (TST90) i częstość akcji serca są silniejszymi predyktorami zdarzeń sercowo-naczyniowych niż indeks AHI, co podkreśla potrzebę nowych narzędzi prognostycznych.

Prognoza przy bezdechu sennym (Bezdech senny)

Obturacyjny bezdech senny (OBS) stanowi istotny problem kliniczny i zdrowia publicznego, ponieważ przyczynia się do niekorzystnego wpływu na jakość życia, występowania objawów dziennych, wypadków drogowych oraz chorób kardiometabolicznych. 1 Zespół ten dotyka około 4% mężczyzn i 2% kobiet na całym świecie. 2 Prognoza przy bezdechu sennym zależy od wielu czynników, w tym nasilenia choroby, współistniejących schorzeń oraz stosowania się do zalecanego leczenia.

Rokowanie krótkoterminowe

Krótkoterminowa prognoza w odniesieniu do objawów takich jak senność w ciągu dnia i chrapanie waha się od dobrej do doskonałej przy regularnym stosowaniu terapii ciągłym dodatnim ciśnieniem w drogach oddechowych (CPAP). 3 Kilka badań, w tym badania kontrolowane placebo, wykazały znaczącą poprawę w zakresie funkcji poznawczych i ogólnego stanu zdrowia (np. mierzonego kwestionariuszem Medical Outcome Study Short-Form 36) po 4-8 tygodniach leczenia CPAP. 4 Należy jednak zauważyć, że badania te nie były przeprowadzane na dużej populacji ani przez okres dłuższy niż 4-8 tygodni leczenia. 5

Rokowanie długoterminowe

Długoterminowa prognoza pozostaje niejasna, ponieważ nie przeprowadzono randomizowanych badań oceniających wpływ CPAP na zapobieganie rozwojowi powikłań sercowo-naczyniowych. 6 Nieleczony ciężki OBS (AHI ≥ 30) wiąże się ze zwiększonym ryzykiem śmiertelności z przyczyn sercowo-naczyniowych, definiowanej jako zawał mięśnia sercowego (MI) lub udar mózgu zakończony zgonem. 7 U pacjentów z łagodnym OBS lub poddawanych leczeniu za pomocą CPAP nie stwierdzono istotnie zwiększonego ilorazu szans w porównaniu z grupą osób bez OBS. 8

W przypadku pacjentów z udarem mózgu, u których występuje OBS, badania wykazały, że bezdech senny wiąże się z przedłużonym pobytem w szpitalu, zwiększonym ryzykiem nawrotu udaru oraz podwyższoną śmiertelnością. 9 Istnieje pilna potrzeba opracowania trafnych narzędzi predykcyjnych do identyfikacji ryzyka OBS wśród tej szczególnie narażonej grupy pacjentów. 10

Czynniki wpływające na prognozę

Nieleczony OBS może skrócić oczekiwaną długość życia i zwiększyć ryzyko niebezpiecznych powikłań. 11 Rokowanie zależy od wielu czynników, takich jak nasilenie choroby i występowanie innych schorzeń współistniejących. 12 Można jednak oczekiwać pozytywnego wyniku, jeśli pacjent będzie przestrzegał planu leczenia, który został ustalony wspólnie z lekarzem prowadzącym. 13

W porównaniu z łagodnym OBS, pacjenci z umiarkowanym do ciężkiego OBS mają bardziej nasilone upośledzenie funkcji wszystkich narządów organizmu. 14 OBS jest niezależnym czynnikiem ryzyka rozwoju wielu chorób ogólnoustrojowych. 15

Modele predykcyjne w ocenie rokowania

Trwają intensywne prace nad opracowaniem modeli predykcyjnych, które mogłyby skuteczniej oceniać rokowanie i potencjalne powikłania u pacjentów z bezdechem sennym.

Modele predykcyjne nasilenia OBS

Model predykcyjny opracowany w jednym z badań wykazuje dobrą moc predykcyjną dla umiarkowanego do ciężkiego OBS i przewyższa inne modele predykcyjne oraz kwestionariusze. 16 Model ten charakteryzuje się dobrą zgodnością w przewidywaniu rzeczywistego występowania umiarkowanego do ciężkiego ryzyka oraz dobrą dokładnością predykcyjną. 17 Analiza decyzyjna (DCA) pokazuje, że korzyść netto z modelu nomogramu jest wyższa niż w przypadku kwestionariuszy SBQ i NoSAS, co wskazuje na dobrą użyteczność kliniczną. 18 Obszar pod krzywą (AUC) dla tego modelu predykcyjnego wynosił 0,976 (95% CI: 0,962-0,990). 19

Wraz ze wzrostem częstości występowania zespołu bezdechu sennego (OBS) na całym świecie, pojawia się potrzeba opracowania nowej metody przesiewowej, która mogłaby zrekompensować wady tradycyjnej metody diagnostycznej, jaką jest polisomnografia (PSG). 20 Badania wykazują, że metody uczenia maszynowego mają znaczny potencjał do wykorzystania w przewidywaniu ciężkości OBS. 21

Modele predykcyjne powikłań sercowo-naczyniowych

Badacze z Mount Sinai otrzymali czteroletni grant w wysokości 3 milionów dolarów z National Heart, Lung, and Blood Institute of the National Institutes of Health (NIH) na opracowanie modeli predykcyjnych opartych na sztucznej inteligencji (AI) w celu identyfikacji ryzyka zdarzeń sercowo-naczyniowych u pacjentów z obturacyjnym bezdechem sennym. 22 Amerykańskie Towarzystwo Kardiologiczne (AHA) wskazuje, że obturacyjny bezdech senny zwiększa ryzyko chorób układu sercowo-naczyniowego, w tym choroby wieńcowej, nadciśnienia tętniczego i udaru mózgu. 23

Zespół badawczy buduje narzędzia oparte na uczeniu maszynowym (ML) w celu identyfikacji pacjentów z OBS o wysokim ryzyku progresji miażdżycy i zdarzeń sercowo-naczyniowych, takich jak udar mózgu i zawał serca. 24 Dane te zostaną wykorzystane do oznaczenia kluczowych predyktorów progresji miażdżycy i zdarzeń sercowo-naczyniowych, a także do identyfikacji podgrup pacjentów opartych na ryzyku, które mają różne wyniki leczenia CPAP w odniesieniu do zdarzeń sercowo-naczyniowych. 25

Naukowcy zauważyli, że obecne narzędzia diagnostyczne dla bezdechu sennego, które zazwyczaj polegają na liczeniu zaburzeń oddychania u pacjenta podczas snu, nie są dokładnymi predyktorami krótko- i długoterminowych niekorzystnych wyników, takich jak nadmierna senność w ciągu dnia, chorobowość sercowo-naczyniowo-mózgowa i upośledzenie neuropoznawcze. 26 Modele AI są zaprojektowane w celu rozwiązania tych niedoskonałości poprzez analizę zmiennych hipoksycznych, pobudzeniowych i wentylacyjnych w celu wygenerowania spersonalizowanej oceny ryzyka pacjenta. 27

Dokładność modeli predykcyjnych

Badacze z Mount Sinai otrzymali również 4,1 miliona dolarów z National Heart, Lung, and Blood Institute (NHLBI) na opracowanie modeli sztucznej inteligencji (AI) do przewidywania niekorzystnych wyników w obturacyjnym bezdechu sennym. 28 Indeks AHI (Apnea-Hypopnea Index) ma jednak ograniczenia i niekoniecznie jest dokładnym predyktorem wyników u pacjentów, co skłania klinicystów do apelowania o opracowanie lepszych narzędzi diagnostycznych i prognostycznych. 29

Wyniki analizy ujawniły, że jeden z modeli może dokładnie przewidywać prawdopodobieństwo senności spowodowanej bezdechem z dokładnością około 87 procent, podczas gdy model wykorzystujący AHI może przewidywać ten sam parametr z dokładnością tylko 54 procent. 30 W kohorcie 4700 uczestników podejście oparte na AI mogło przewidywać śmiertelność sercowo-naczyniową z dokładnością ponad 80 procent w porównaniu do standardowego podejścia, które osiągnęło tylko 58 procent dokładności. 31

Czynniki fizjologiczne wpływające na rokowanie

Wskaźniki predykcyjne wyników sercowo-naczyniowych

Indeks bezdechów i spłyceń oddychania (AHI) nie przewidywał poważnych zdarzeń sercowo-naczyniowych (MACEs) (HR: 0,95; 95% CI 0,76 do 1,17), podczas gdy czas snu z saturacją tlenem ≤ 90% (TST90) (HR: 1,41; 95% CI 1,10 do 1,81) był niezależnym predyktorem MACEs, podobnie jak częstość akcji serca w stanie czuwania i w nocy. 32 Hipoksja związana z OBS i średnia częstość akcji serca, ale nie indeks bezdechów i spłyceń oddychania (AHI), są prawdopodobnie dominującymi predyktorami niekorzystnych wyników sercowo-naczyniowych. 33

W umiarkowanym do ciężkiego OBS (n=1108), u których wskazane było leczenie CPAP, regularne stosowanie CPAP nie było związane ze zmniejszeniem występowania MACEs. 34 Nie wszyscy pacjenci z umiarkowanym do ciężkiego OBS według kryteriów AHI odnosili jednolite korzyści z regularnej terapii CPAP, ale ci, którzy byli młodsi, z większą hipoksemią nocną, wyższym AHI i innymi współistniejącymi czynnikami ryzyka sercowo-naczyniowego, wykazywali niższą częstość występowania zdarzeń sercowo-naczyniowych przy regularnym leczeniu CPAP. 35

Wysokie wzmocnienie pętli jako czynnik patogenetyczny

Wysokie wzmocnienie pętli (niestabilna kontrola wentylacyjna) jest ważnym, ale trudnym do zmierzenia czynnikiem przyczyniającym się do patogenezy obturacyjnego bezdechu sennego (OBS), przewidującym następstwa OBS i/lub odpowiedź na leczenie. 36 Przewidywane wzmocnienie pętli wykazało umiarkowaną do wysokiej korelację z referencyjnym wzmocnieniem pętli (r=0,48; 95% CI 0,38-0,57) oraz umiarkowaną zdolność różnicowania pacjentów z wysokim i niskim wzmocnieniem pętli (pole pod krzywą=0,73; 95% CI 0,67-0,80). 37

Jest to pierwszy model predykcyjny wzmocnienia pętli oparty na łatwo dostępnych danych klinicznych, który może ułatwić retrospektywne analizy istniejących zbiorów danych, lepszy dobór pacjentów do badań klinicznych, a ostatecznie także praktykę kliniczną. 38 Ten model predykcyjny może ułatwić lepszy dobór pacjentów do badań klinicznych: pacjenci, u których przewiduje się wysokie wzmocnienie pętli, mogliby być preferencyjnie wybierani do badań interwencji obniżających wzmocnienie pętli (np. acetazolamid, tlen), ale wykluczani z interwencji ukierunkowanych na inne cechy, takie jak anatomia (np. chirurgia górnych dróg oddechowych, aparaty doustne, stymulacja nerwu podjęzykowego). 39

Personalizacja medycyny w prognozowaniu OBS

Coraz większa świadomość heterogeniczności obturacyjnego bezdechu sennego (OBS) skłania do poszukiwania bardziej spersonalizowanych metod prognostycznych i terapeutycznych. 40

Podtypy kliniczne i ich wpływ na rokowanie

Regularne leczenie CPAP nie było związane z niższym wskaźnikiem MACE, ale analiza klasterowa oparta na wyjściowych cechach klinicznych i PSG zidentyfikowała podgrupę wysokiego ryzyka, która mogła odnieść korzyści z regularnego leczenia CPAP. 41 Wyniki te dodatkowo potwierdzają, że świadomość heterogeniczności OBS umożliwiłaby lepszą identyfikację osób zagrożonych określonymi niekorzystnymi wynikami zdrowotnymi i tych, którzy najprawdopodobniej skorzystają z leczenia CPAP. 42

Określone podtypy objawów okazały się niezależnymi predyktorami występującej choroby sercowo-naczyniowej i mózgowo-naczyniowej w umiarkowanym do ciężkiego obturacyjnego bezdechu sennego, a wśród pacjentów z obturacyjnym bezdechem sennym (podtyp nadmiernie senny) stwierdzono zwiększone ryzyko wystąpienia incydentów sercowo-naczyniowych i mózgowo-naczyniowych. 43

Indywidualizacja leczenia w oparciu o endotypy fizjologiczne

Dalsza precyzacja specyficznych endotypów fizjologicznych u osób z obturacyjnym bezdechem sennym może ułatwić rozwój nowych metod leczenia, które można dostosować do indywidualnych potrzeb pacjenta, zgodnie z endotypem lub endotypami fizjologicznymi ich choroby. 44 Endotypy te mogą pomóc w identyfikacji pacjentów, u których mogą wystąpić większe poprawy objawów i bardziej wyraźne odpowiedzi na określone metody leczenia obturacyjnego bezdechu sennego. 45

Bardziej precyzyjne fenotypowanie molekularne obturacyjnego bezdechu sennego za pomocą tych i innych markerów mogłoby zapewnić bardziej zniuansowaną reprezentację choroby. 46 Ostatecznie to zaawansowane fenotypowanie mogłoby zapewnić bardziej dokładną opiekę, dopasowując precyzyjne podtypy do konkretnych metod leczenia. 47

Skuteczność terapii PAP

Terapia dodatnim ciśnieniem w drogach oddechowych (PAP) jest przepisywana pacjentom z obturacyjnym bezdechem sennym (OBS). 48 Badania kliniczne dotyczące leczenia CPAP w zakresie ochrony układu sercowo-naczyniowego były w większości negatywne. 49

Obecne badanie potwierdza stale rosnący zbiór literatury wzywającej do większego zastanowienia się i przedstawienia dowodów na poparcie definicji przestrzegania terapii PAP, która jest klinicznie znacząca. 50 Badanie nie wykazało istotnych różnic między grupami przestrzegającymi i nieprzestrzegającymi terapii PAP w zakresie śmiertelności, długości pobytu w szpitalu i liczby hospitalizacji w ośmioletnim okresie obserwacji. 51 Badanie to potwierdza ustalenia poprzednich randomizowanych badań klinicznych dotyczące braku związku między przestrzeganiem terapii PAP a śmiertelnością lub innymi wynikami klinicznymi. 52 Pomimo tego, badanie nadal nie wykazało istotnych różnic w wynikach między grupami przestrzegającymi i nieprzestrzegającymi terapii PAP. 53

Nowe perspektywy w prognozowaniu OBS

W niedalekiej przyszłości dokładność prognostyczna tych pomiarów w przewidywaniu długoterminowych powikłań w obturacyjnym bezdechu sennym prawdopodobnie się poprawi, wraz z lepszym dopasowaniem metod leczenia do podtypów choroby. 54 Czynniki te mogą pomóc lepiej zrozumieć patologiczną podstawę obturacyjnego bezdechu sennego i jego powikłań, poprawić prognozę długoterminowych skutków zdrowotnych oraz lepiej dopasować pacjentów do bardziej specyficznych metod leczenia. 55

Wysokie (34%) proporcje normalnych wyników potwierdza potrzebę wstępnej oceny przed polisomnografią, co sprawia, że poszukiwanie zwalidowanego modelu do badania przesiewowego pacjentów z podejrzeniem obturacyjnego bezdechu sennego jest niezbędne, szczególnie na poziomie podstawowej opieki zdrowotnej. 56 W tym wyniku klinicznym modele diagnostyczne muszą mieć wysoką czułość, ponieważ należy unikać wyników fałszywie ujemnych, aby zapobiec wykluczeniu pacjentów z umiarkowanym lub ciężkim OBS z wykonywania polisomnografii (PSG), standardowego testu do ostatecznej diagnozy OBS. 57

Najważniejszymi czynnikami ryzyka są: płeć, wiek, obwód szyi oraz nieprawidłowości twarzoczaszki i górnych dróg oddechowych, a czynnikami diagnostycznymi są: obserwowane bezdechy i nokturia. 58 Choć modele prognostyczne nie są doskonałe, mogą pomóc w identyfikacji ponad 90% pacjentów z OBS przy jednoczesnym wykluczeniu 25% zdrowych pacjentów, co złagodziłoby obciążenie służby zdrowia poprzez zmniejszenie liczby niepotrzebnych konsultacji i list oczekujących na polisomnografię. 59

    Obstructive sleep apnoea is a substantial clinical and public health problem because it contributes to harmful effects on quality of life, daytime symptoms, road traffic incidents, and cardiometabolic disease. […] In the near future, the prognostic accuracy of these measures in predicting long term complications in obstructive sleep apnoea will likely be improved, together with better matching of treatments to disease subtypes. […] We believe that these factors might help us better understand the pathological basis of obstructive sleep apnoea and its complications, improve the prognosis for the long term effects on health, and better match patients to more specific treatments. […] Particular symptom subtypes were shown to be independent predictors of prevalent cardiovascular and cerebrovascular disease in moderate-to-severe obstructive sleep apnoea, and an increased risk of incident cardiovascular and cerebrovascular disease among patients with obstructive sleep apnoea (excessively sleepy subtype) was found.

    In obstructive sleep apnea, respiratory effort is maintained but ventilation decreases/disappears due to upper-airway partial/total occlusion. This condition affects about 4% of men and 2% of women worldwide. […] The high (34%) proportion of normal results confirms the need for a pre-evaluation prior to polysomnography, making the search for a validated model to screen patients with suspicion of obstructive sleep apnea essential, especially at primary care level. […] In this clinical outcome, diagnostic models need to have a high sensitivity, as false negatives should be avoided, to prevent excluding patients with moderate or severe OSA from performing polysomnography (PSG), the standard test for OSA final diagnosis. […] This study is one of the first to build and validate risk models for OSA based solely on clinical and demographic variables, which have the key advantage of being easily available and quickly acquired.

    The short-term prognosis, in relation to symptoms such as daytime sleepiness and snoring, ranges from good to excellent with regular use of CPAP. Several studies, including placebo-controlled studies, have shown significant improvement in measures of cognitive function and general health status (eg, as measured by the Medical Outcome Study Short-Form 36 health survey) after 4-8 weeks of treatment with CPAP. However, studies have not been performed in a large population or for more than a 4- to 8-week treatment period. […] The long-term prognosis is unknown because no randomized treatment studies investigating the effect of CPAP on preventing the development of cardiovascular sequelae have been conducted. […] The effect of OSA on mortality has been investigated using observational cohort studies. Marin et al found in a Spanish cohort that severe untreated OSA (AHI 30) is associated with an increased risk of cardiovascular mortality, defined by fatal myocardial infarction (MI) or stroke. Patients with mild OSA or those undergoing treatment with CPAP did not have a significantly increased odds ratio compared with a group of subjects without OSA. […] All of the above evidence strongly suggests that OSA is an independent risk factor for the development of cardiovascular disease and death. However, at this time, no definitive randomized studies have investigated the effect of CPAP in preventing the potential cardiovascular risks.

    OSA is an independent risk factor for several systemic diseases. […] Compared with mild OSA, patients with moderate-to-severe OSA have more severe impairment in the function of all organs of the body.

    Further clarification of specific physiological endotypes in individuals with obstructive sleep apnoea might facilitate the development of new treatments that can be tailored to individual patient needs according to the physiological endotype or endotypes of their disease. […] Hence these endotypes could help in identifying patients who might have greater improvements in symptoms and more robust responses to specific treatments for obstructive sleep apnoea. […] A more precise molecular phenotyping of obstructive sleep apnoea with these and other markers could provide a more nuanced representation of the disease. Ultimately, this advanced phenotyping might provide more accurate care, matching precise subtypes to specific treatments.

    Positive airway pressure (PAP) therapy is prescribed to patients with obstructive sleep apnea (OSA). […] The present study supports a steadily growing body of literature calling for more consideration and evidence to support a definition of PAP therapy adherence that is clinically meaningful. […] Our study showed no significant differences between the PAP therapy adherent and non-adherent groups for mortality, length of stay in hospital, and number of hospitalizations during the eight-year study observation period. […] The present study supports the findings of previous RCTs regarding the lack of association between PAP therapy adherence and mortality or other clinical outcomes. […] Despite this, our study still didn’t find significant differences in outcomes between the PAP therapy adherent and non-adherent groups. […] This exploratory study warrants that further studies be conducted to investigate clinically meaningful criteria for PAP therapy adherence.
  • #49 Cardiovascular outcomes in obstructive sleep apnoea and implications of clinical phenotyping on effect of CPAP treatment | Thorax
    https://thorax.bmj.com/content/78/1/76
    There is a growing awareness of the heterogeneity of obstructive sleep apnoea (OSA). […] Clinical trials of CPAP treatment on cardiovascular protection have been mostly negative. […] We aimed to assess the association between polysomnographic parameters and incident major adverse cardiovascular events (MACEs), and to investigate if the CPAP effect could be better delineated among clinical subgroups. […] Apnoea-hypopnoea index (AHI) did not predict MACEs (HR: 0.95; 95% CI 0.76 to 1.17), whereas sleep time with oxygen saturation 90% (TST90) (HR: 1.41; 95% CI 1.10 to 1.81) was an independent predictor of MACEs, as were wake and nocturnal heart rate. […] In moderate-severe OSA (n=1108) who were indicated for CPAP treatment, regular CPAP was not associated with reduction of incident MACEs.

    Obstructive sleep apnoea is a substantial clinical and public health problem because it contributes to harmful effects on quality of life, daytime symptoms, road traffic incidents, and cardiometabolic disease. […] In the near future, the prognostic accuracy of these measures in predicting long term complications in obstructive sleep apnoea will likely be improved, together with better matching of treatments to disease subtypes. […] We believe that these factors might help us better understand the pathological basis of obstructive sleep apnoea and its complications, improve the prognosis for the long term effects on health, and better match patients to more specific treatments. […] Particular symptom subtypes were shown to be independent predictors of prevalent cardiovascular and cerebrovascular disease in moderate-to-severe obstructive sleep apnoea, and an increased risk of incident cardiovascular and cerebrovascular disease among patients with obstructive sleep apnoea (excessively sleepy subtype) was found.

    In obstructive sleep apnea, respiratory effort is maintained but ventilation decreases/disappears due to upper-airway partial/total occlusion. This condition affects about 4% of men and 2% of women worldwide. […] The high (34%) proportion of normal results confirms the need for a pre-evaluation prior to polysomnography, making the search for a validated model to screen patients with suspicion of obstructive sleep apnea essential, especially at primary care level. […] In this clinical outcome, diagnostic models need to have a high sensitivity, as false negatives should be avoided, to prevent excluding patients with moderate or severe OSA from performing polysomnography (PSG), the standard test for OSA final diagnosis. […] This study is one of the first to build and validate risk models for OSA based solely on clinical and demographic variables, which have the key advantage of being easily available and quickly acquired.

    We present as main risk factors: gender, age, neck circumference, and craniofacial and upper-airway abnormalities, and as diagnostic factors: witnessed apneas and nocturia. […] According to our cross-validated evaluation, we expected around 30% of false positives which, although unwanted, is nonetheless an improvement if we compare with all patients at risk being referred to sleep consultation and polysomnography. Nonetheless, we were able to rule out 25% of healthy patients, which, in our understanding, would alleviate health services by reducing the burden of unneeded consultations and the wait lists for polysomnography, while identifying more than 90% of patients with OSA.
