Dystrofia mięśniowa
Zapobieganie i profilaktyka
Dystrofia mięśniowa (DM) to grupa genetycznych schorzeń charakteryzujących się postępującym osłabieniem i zanikiem mięśni, z których najczęściej omawianą jest dystrofia Duchenne’a (DMD). Diagnostyka opiera się na badaniach genetycznych, które umożliwiają wykrycie mutacji z około 95% dokładnością prenatalnie, a także na oznaczeniu aktywności kinazy kreatynowej (CK) w surowicy, wykrywającej nosicielstwo u około 70-90% kobiet. Wczesne rozpoznanie jest kluczowe dla wdrożenia profilaktyki i terapii, w tym stosowania leków kardiologicznych od 10. roku życia, co opóźnia rozwój kardiomiopatii i wydłuża przeżycie (mediana 26,4 vs. 23,3 roku). Kortykosteroidy przedłużają zdolność chodzenia i opóźniają progresję skoliozy, a szczepienia przeciwko grypie i pneumokokom są niezbędne ze względu na ryzyko powikłań płucnych. Fizjoterapia, obejmująca pasywne rozciąganie, ćwiczenia zakresu ruchu i stymulację mięśni, zapobiega przykurczom i utrzymuje funkcję mięśniową, natomiast ortotyka i leczenie skoliozy (fuzja kręgosłupa przy kącie Cobba 20-30°) wspierają mobilność i funkcję oddechową.

Dystrofia mięśniowa – Profilaktyka i zapobieganie
Dystrofia mięśniowa (łac. dystrophia musculorum) to grupa genetycznych schorzeń charakteryzujących się postępującym osłabieniem i zanikiem mięśni. Ze względu na genetyczne podłoże tych chorób, obecnie nie istnieją metody, które mogłyby całkowicie zapobiec ich wystąpieniu. Dystrofie mięśniowe nie występują w wyniku czynników zewnętrznych, takich jak infekcje, poziomy aktywności czy urazy, co sprawia, że nie są chorobami, którym można zapobiec w tradycyjnym rozumieniu profilaktyki medycznej.123
Poradnictwo genetyczne jako kluczowy element prewencji
Jednym z najważniejszych aspektów zapobiegania dystrofii mięśniowej jest poradnictwo genetyczne dla rodzin z historią tej choroby. W przypadku dystrofii Duchenne’a (DMD) i innych form dystrofii mięśniowych, około jednej trzeciej przypadków występuje przypadkowo, bez wcześniejszej historii rodzinnej tego schorzenia.4 Dla par planujących potomstwo, które mają obawy dotyczące ryzyka przekazania dystrofii mięśniowej, zaleca się konsultację z lekarzem genetykiem.56
W niektórych sytuacjach dostępne są testy prenatalne, które mogą zdiagnozować obecność dystrofii mięśniowej we wczesnej ciąży. Duchenne’a dystrofia mięśniowa może być wykryta z około 95% dokładnością za pomocą badań genetycznych wykonywanych w trakcie ciąży.7 Osoby zagrożone mogą również rozważyć sprawdzenie zarodków i implantację tylko tych, które nie mają genów dystrofii mięśniowej.89
Diagnostyka nosicielek wśród krewnych płci żeńskiej pacjentów może być przeprowadzona poprzez badania heterozygotyczne, z których oznaczenie aktywności kinazy kreatynowej (CK) w surowicy jest prawdopodobnie nadal najbardziej wiarygodną metodą, pozwalającą na wykrycie około 70% dorosłych i prawdopodobnie do 90% nosicielek w wieku szkolnym.10
Wczesna diagnostyka jako element zapobiegania powikłaniom
Wczesna i precyzyjna diagnostyka choroby jest niezbędnym elementem skutecznej strategii zarządzania chorobą, ponieważ wytyczne dotyczące opieki i zapobiegania poprzez poradnictwo muszą być wdrożone jak najwcześniej, szczególnie, że dla części pacjentów dostępne są już terapie.1112
Regularne badania lekarskie i testy genetyczne mogą pomóc w identyfikacji osób, które mogą być zagrożone lub być nosicielami mutacji genowych związanych z dystrofią mięśniową. Wcześnie identyfikując te osoby, pracownicy służby zdrowia mogą zapewnić odpowiednie poradnictwo, wskazówki i wsparcie w skutecznym zarządzaniu chorobą.13
Profilaktyka powikłań dystrofii mięśniowej
Chociaż dystrofii mięśniowej nie można zapobiec, istnieją kroki, które można podjąć, aby zapobiec lub opóźnić powikłania i poprawić jakość życia osób dotkniętych tym schorzeniem.14
Profilaktyczne leczenie kardiologiczne
Wczesne profilaktyczne leczenie standardowymi lekami na serce — gdy są podawane przed wystąpieniem problemów kardiologicznych — wydłuża przeżycie u mężczyzn z dystrofią mięśniową Duchenne’a (DMD), zgodnie z danymi z amerykańskiej sieci Muscular Dystrophy Surveillance, Tracking and Research Network (MD STARnet).15
Obecne zalecenia dotyczące leczenia problemów sercowych w DMD obejmują rozpoczęcie stosowania leków na serce — szczególnie tych, które obniżają ciśnienie krwi — w wieku 10 lat. Ma to na celu opóźnienie początku lub spowolnienie postępu kardiomiopatii.16
Badania wykazały, że profilaktyczne leki na serce podawane przed wystąpieniem dysfunkcji lewej komory (LVD) wydłużały przeżycie pacjentów z DMD, ponieważ leczeni pacjenci żyli dłużej niż nieleczeni pacjenci (mediana 26,4 vs. 23,3 roku).17 Mimo przekonujących dowodów na korzyści płynące z profilaktyki w opóźnianiu kardiomiopatii, profilaktyczne stosowanie leków kardiologicznych w Stanach Zjednoczonych nie zostało szeroko przyjęte – tylko jedna czwarta osób otrzymała leczenie profilaktyczne.18
Terapia kortykosteroidowa
Terapia kortykosteroidowa może przedłużyć życie i opóźnić utratę zdolności chodzenia. Istnieją dowody, że terapia kortykosteroidowa może przedłużyć możliwość chodzenia, zapobiec/opóźnić rozwój i progresję skoliozy oraz wydłużyć oczekiwaną długość życia.19
Mechanizm, poprzez który kortykosteroidy opóźniają pogorszenie funkcji, nie jest znany, ale uważa się, że obejmuje hamowanie procesu zapalnego i bliznowacenia związanego z rozpadem tkanki mięśniowej.20
Szczepienia profilaktyczne
Ze względu na upośledzenie czynności płuc w późnym stadium choroby, wszyscy pacjenci z dystrofią mięśniową powinni być odpowiednio zaszczepieni przeciwko grypie i pneumokokom.21 Szczepionka przeciwko pneumokokom (podawana raz) pomaga zapobiegać zapaleniu płuc, a coroczna szczepionka przeciwko grypie jest zalecana dla dzieci w wieku sześciu miesięcy i starszych.22
Profilaktyka ortopedyczna i fizjoterapia
Fizjoterapia może pomóc w zapobieganiu deformacjom, zwiększeniu mobilności i utrzymaniu siły i elastyczności mięśni u pacjentów z dystrofią mięśniową.23 Program fizjoterapii może obejmować:
- Pasywne rozciąganie w celu zwiększenia elastyczności stawów i zapobiegania przykurczom
- Ćwiczenia zakresu ruchu w celu zwiększenia siły mięśni
- Ćwiczenia zapobiegające zanikowi mięśni
- Ćwiczenia głębokiego oddychania, aby utrzymać płuca w pełni rozszerzone
- Elektryczną stymulację mięśni24
Fizjoterapia odgrywa pozytywną rolę w utrzymaniu siły i spowolnieniu rozwoju przykurczów.25 Ćwiczenia (aktywne i pasywne) są ważnym aspektem w leczeniu DMD. Do wieku około 8 lat chłopcy mogą uczestniczyć w zwykłej aktywności fizycznej. Jednak ważne jest, aby nie przeciążać się (ćwiczyć do wyczerpania), ponieważ zbyt intensywne ćwiczenia lub niewłaściwy rodzaj ćwiczeń może spowodować dodatkowe uszkodzenie mięśni.26
Bierne ćwiczenia lub wspomagane rozciąganie powinny być ustanowione jak najwcześniej. Programy ćwiczeń opracowane przez fizjologów ćwiczeń i fizjoterapeutów mają na celu zapobieganie (w miarę możliwości) skracaniu mięśni lub przykurczom, które mogą ograniczać ruch stawów.27
Ortotyka i zaopatrzenie ortopedyczne
Ortotyka kończyn dolnych, a później blokujące ortezy kolano-kostka-stopa (KAFO) będą wspierać i mogą przedłużyć możliwość chodzenia. Ortezy kręgosłupa lub formowane siedziska wózków inwalidzkich mogą opóźnić progresję skoliozy, ale zwykle wskazana jest fuzja kręgosłupa.28
Postępujące przykurcze mogą być poprawione poprzez wydłużanie ścięgien, ale wskaźniki nawrotów mogą być wysokie. Skolioza powinna być leczona wcześnie za pomocą instrumentacji kręgosłupa tylnego i fuzji, często zalecanej, gdy kąt Cobba osiąga 20-30 stopni. Wcześniejsza fuzja jest zalecana, aby uniknąć pogorszenia funkcji płuc i ryzyka związanego z bardziej zaawansowaną kardiomiopatią.29
Profilaktyka sercowo-płucna
Badanie przesiewowe (zwykle za pomocą echokardiografii lub rezonansu magnetycznego serca [MRI]) i wczesne leczenie kardiomiopatii, rozpoczynające się w momencie diagnozy lub około szóstego roku życia. Nosicielki płci żeńskiej mogą być badane od wieku nastoletniego.30
Leczenie płuc podczas snu (nocna nieinwazyjna wentylacja) lub pomoc oddechowa w okresach infekcji płuc jest zalecana. Badanie czynności płuc powinno rozpocząć się około 9 lub 10 roku życia, zanim dziecko będzie potrzebowało wózka inwalidzkiego, i powinno być powtarzane kilka razy w roku, gdy czynność płuc pogarsza się lub dziecko wymaga wózka inwalidzkiego.31
Dieta i suplementacja
Gęstość kości powinna być utrzymywana, aby zmniejszyć ryzyko złamań, zapewniając dziecku dietę bogatą w wapń i witaminę D.32 Obecnie nie ma dowodów potwierdzających profilaktyczne stosowanie bisfosfonianów.33
Ogólnie rzecz biorąc, chociaż zmiany w diecie nie mogą spowolnić postępu dystrofii mięśniowej, zdrowa dieta jest niezbędna dla ogólnego zdrowia. Ograniczona mobilność spowodowana osłabieniem mięśni może spowodować, że pacjent przybierze na wadze, odwodni się i doświadczy zaparć. Dobrze zbilansowana dieta o wysokiej zawartości błonnika, wysokiej zawartości białka i niskiej kaloryczności może pomóc zrównoważyć te problemy.34
Nowe perspektywy w profilaktyce dystrofii mięśniowej
Badania nad edycją genetyczną
Wyniki badań pokazują, że edycja genomowa za pomocą systemu CRISPR/Cas9 jest zdolna do korygowania pierwotnej zmiany genetycznej odpowiedzialnej za dystrofię mięśniową (DMD) i zapobiegania rozwojowi charakterystycznych cech tej choroby u myszy mdx.35
Edycja genomowa w linii zarodkowej nie jest obecnie możliwa u ludzi. Jednak edycję genomową można, w zasadzie, wyobrazić sobie w komórkach poporodowych in vivo, jeśli pewne wyzwania techniczne mogłyby zostać przezwyciężone. Mimo tych wyzwań, wraz z szybkim postępem technologicznym systemów dostarczania genów i usprawnieniami systemu edycji CRISPR/Cas9, opisane podejście mogłoby ostatecznie przynieść korzyści terapeutyczne DMD i innym ludzkim chorobom genetycznym w przyszłości.36
Leczenie eksperymentalne
Trwają badania nad innymi metodami leczenia, takimi jak wymiana genów, wstrzyknięcia komórek macierzystych i modyfikacja genów. Nadzieja jest taka, że w przyszłości te metody mogłyby odwrócić uszkodzenie mięśni spowodowane przez dystrofię mięśniową.37
W przypadku leku Duvyzat, firma została poproszona o przeprowadzenie randomizowanego badania kontrolowanego placebo u chodzących pacjentów z DMD oraz porejestracyjnego badania skuteczności i bezpieczeństwa w oparciu o dane z rejestru pacjentów dzieci z DMD w wieku sześciu lat i starszych leczonych givinostatem.38
Zalecenia dla osób z dystrofią mięśniową
Jeśli masz dystrofię mięśniową, istnieją kroki, które możesz podjąć, aby zapobiec lub opóźnić powikłania i poprawić jakość życia, w tym:
- Jedz zdrową dietę, aby zapobiec niedożywieniu
- Pij dużo wody, aby uniknąć odwodnienia i zaparć
- Ćwicz jak najwięcej zgodnie z zaleceniami zespołu opieki zdrowotnej
- Utrzymuj zdrową wagę
- Rzuć palenie, aby chronić płuca i serce
- Bądź na bieżąco ze szczepieniami3940
Ważne jest, aby pamiętać, że dystrofia mięśniowa jest chorobą postępującą, dlatego utrzymanie obecnych poziomów funkcji uczestników pozostaje bardzo korzystne dla nich i może pomóc w przedłużeniu ich życia.41
W połączeniu z opcjami leczenia, prowadzenie zdrowego stylu życia może poprawić jakość życia z chorobą. Utrzymuj zdrową dietę, nie pal ani nie pij alkoholu, pij dużo wody i utrzymuj zdrową wagę, aby dać sobie najlepsze szanse na skuteczne leczenie.42

Recently DNA sequencing analysis has played a vital role in the unambiguous diagnosis of clinically suspected patients with Duchenne Muscular Dystrophy (DMD). […] Early and precise diagnosis of the disease is an essential part of an effective disease management strategy as care guidelines and prevention through counseling need to be initiated at the earliest particularly since therapies are now available for a subset of patients. […] Given that the burden of care for DMD patients invariably falls on the mothers, particularly in rural India, effective genetic counseling followed by carrier screening is crucial for prevention of this disorder. […] Our comprehensive efforts, involving complete genetic testing coupled with compassionate genetic counseling provided to DMD patients and their families, are intended to improve the quality of life of DMD patients and to empower carrier females to make informed reproductive choices to impede the propagation of this deadly disease.

DMD is an incurable disease; therefore most effort, in research as well as in practical medicine, is concentrated upon its prevention. […] Unfortunately the disease cannot yet be diagnosed prenatally. Potential DMD carriers among female relatives of the patients may be identified by pathological heterozygote tests, of which determination of serum CK activity is probably still the most reliable method, allowing the detection of about 70% of adult and probably up to 90% of carriers at school age. […] Finally, it is believed that the two most important preventive problems in DMD, carrier detection and prenatal diagnosis, will ultimately be solved by means of the rapidly advancing DNA technology.

Prevention plays a crucial role in addressing muscular dystrophy, a group of genetic disorders characterized by progressive muscle weakness and degeneration. While there is currently no cure for muscular dystrophy, taking proactive measures to prevent its onset or delay its progression can significantly improve the quality of life for individuals affected by this condition. One key aspect of prevention is early detection. Regular medical check-ups and genetic testing can help identify individuals who may be at risk or carry the gene mutations associated with muscular dystrophy. By identifying these individuals early on, healthcare professionals can provide appropriate counseling, guidance, and support to manage the condition effectively. […] Another important aspect of prevention is adopting a healthy lifestyle. Engaging in regular physical activity, maintaining a balanced diet, and avoiding harmful habits such as smoking or excessive alcohol consumption can contribute to overall muscle health and reduce the risk of developing muscular dystrophy. Furthermore, staying informed about advancements in medical research and treatment options is crucial for prevention efforts. As scientific understanding of muscular dystrophy continues to evolve, new preventive strategies may emerge. By staying up-to-date with the latest developments in this field, individuals at risk or with a family history of muscular dystrophy can make informed decisions about their health and seek appropriate interventions when necessary.

[…] Given the high prevalence of death from cardiovascular (CV) causes in DMD, mortality improvement and delaying progression of CV diseases have been researched extensively. […] Because of pulmonary compromise late in the disease course, all patients with MD should be appropriately vaccinated against influenza and pneumococcus. To promote increased bone density, calcium and vitamin D should be given. Currently, there is no evidence supporting the prophylactic use of bisphosphonates.

Recommendations for managing and preventing problems in these children include: […] Pneumococcal vaccine (given once) to help prevent pneumonia, and annual influenza vaccine for children six months of age and older. […] Screening (usually by echocardiography or cardiac magnetic resonance imaging [MRI]) and early treatment for cardiomyopathy, starting at the time of diagnosis or at around age six years. Female carriers may be screened beginning in the teens. […] Lung treatment while sleeping (nocturnal noninvasive ventilation) or respiratory assistance during periods of lung infection is recommended. Lung function testing should begin around age 9 or 10 years, before the child requires a wheelchair, and should be repeated several times per year when lung function worsens or the child requires a wheelchair.

Corticosteroid therapy may prolong life and delay loss of ambulation […] There is some evidence that corticosteroid therapy may prolong ambulation, prevent/delay scoliosis development and progression, and prolong life expectancy. […] The mechanism by which corticosteroids delay functional decline is unknown but it is thought to involve inhibition of the inflammation and scarring associated with the breakdown of muscle tissue. […] Physical Therapy has a positive role in maintaining strength and slowing the development of contractures. […] Orthotic Management Lower Extremity FOs and later locking KAFOs will support and may prolong ambulation. […] Spinal orthosis or molded wheelchair seats may delay progression of scoliosis but fusion is usually indicated in progressive curves. […] Progressive contractures may be improved with tendon lengthening but recurrence rates may be high. […] Scoliosis should be addressed early with posterior spinal instrumentation and fusion, often recommended when the Cobb angle reaches 20-30 degrees. […] Earlier fusion is recommended to avoid pulmonary functional decline and risks associated with more advanced cardiomyopathy.

Muscular dystrophy treatment varies widely and since there’s no cure, preventative measures are really only management tools to put off its detrimental effects for as long as possible. […] These treatment options can help prevent or reduce issues in the joints and spine versus focusing on the muscles themselves. This helps those suffering from DMD to remain as mobile as possible for as long as possible. […] Exercise (active and passive) is an important aspect in the management of DMD. Up to the age of approximately 8yrs, boys may participate in usual physical activity. However, it is important not to over-exert (exercise to the point of exhaustion) as too much exercise, or the wrong type of exercise may cause additional muscle damage. […] Passive exercise or assisted stretching should be established as early as possible. Exercise programs developed by Exercise Physiologists and Physiotherapists aim to prevent (as much as possible) the shortening of muscles or contracture; which can limit movement of joints. […] It is important to remember that DMD is a progressive disease, therefore maintaining the participants current levels of function remains very beneficial for them and could possibly help to prolong their life.

Preventing and treating complications of DMD â Early identification of children who are affected by DMD is important to prevent complications and prolong life. Recommendations for managing and preventing problems in these children include: […] Pneumococcal vaccine (given once) to help prevent pneumonia, and annual influenza vaccine for children six months of age and older. […] Screening (usually by echocardiography or cardiac magnetic resonance imaging [MRI]) and early treatment for cardiomyopathy, starting at the time of diagnosis or at around age six years. Female carriers may be screened beginning in the teens. […] Lung treatment while sleeping (nocturnal noninvasive ventilation) or respiratory assistance during periods of lung infection is recommended. Lung function testing should begin around age 9 or 10 years, before the child requires a wheelchair, and should be repeated several times per year when lung function worsens or the child requires a wheelchair.

Bone density should be maintained to reduce the risk of fractures by ensuring that the child has a diet rich in calcium and vitamin D. […] Physical therapy can help to maintain muscle function and prevent joint stiffening (contractures). […] Leg braces can assist with standing and walking. […] Surgery can help correct joint contractures, especially at the ankle. […] Scoliosis, or curvature of the spine, is a common complication of DMD. When severe, it can cause breathing problems, so that surgical treatment may be necessary. Spinal fusion operations have been very effective in correcting deformities and maintaining an upright sitting position in a wheelchair. In less severe cases, braces may be effective.

To date, there is no definitive cure for any of the MDs. Treatment revolves largely around managing and/or preventing disease complications to improve muscle strength, survival, and quality of life. […] Given the high prevalence of death from cardiovascular (CV) causes in DMD, mortality improvement and delaying progression of CV diseases have been researched extensively. […] Because of pulmonary compromise late in the disease course, all patients with MD should be appropriately vaccinated against influenza and pneumococcus. To promote increased bone density, calcium and vitamin D should be given. Currently, there is no evidence supporting the prophylactic use of bisphosphonates.

Theres no cure for muscular dystrophy, although certain treatments can help control some symptoms and reduce the risk of complications, regardless of your age at diagnosis or what type of muscular dystrophy you have. […] In general, although dietary changes cant slow the progression of muscular dystrophy, a healthy diet is essential for overall health. Limited mobility from muscle weakness can cause you or your child to gain weight, become dehydrated, and experience constipation. A well-balanced diet that is high-fiber, high-protein, and low-calorie can help offset these issues. […] The goal of muscular dystrophy treatment is to help people with the condition manage its symptoms and potentially slow the progression of the disease. This allows people with muscular dystrophy to remain mobile, independent, and relatively healthy longer. […] Research is ongoing into other treatment methods, such as gene replacement, stem cell injections, and gene modification. The hope is that in the future, these methods could reverse the muscle damage that muscular dystrophy causes.
- #35 Prevention of muscular dystrophy in mice by CRISPR/Cas9âmediated editing of germline DNAhttps://pmc.ncbi.nlm.nih.gov/articles/PMC4398027/
Our results show that CRISPR/Cas9mediated genomic editing is capable of correcting the primary genetic lesion responsible for muscular dystrophy (DMD) and preventing development of characteristic features of this disease in mdx mice. […] Because genome editing in the germ line produced genetically corrected animals with a wide range of mosaicism (2 to 100%), we were able to compare the percentage of genomic correction with the extent of rescue of normal muscle structure and function. […] We propose that the latter type of myofiber arises from the recruitment of corrected satellite cells into damaged myofibers, forming mosaic myo-fibers with centralized nuclei. […] Thus, direct editing of satellite cells in vivo by the CRISPR/Cas9 system represents a potentially promising alternative approach to promote muscle repair in DMD.
- #36 Prevention of muscular dystrophy in mice by CRISPR/Cas9âmediated editing of germline DNAhttps://pmc.ncbi.nlm.nih.gov/articles/PMC4398027/
Genomic editing within the germ line is not currently feasible in humans. […] However, genomic editing could, in principle, be envisioned within postnatal cells in vivo if certain technical challenges could be overcome. […] Despite the challenges listed above, with rapid technological advances of gene delivery systems and improvements to the CRISPR/Cas9 editing system, the approach we describe could ultimately offer therapeutic benefit to DMD and other human genetic diseases in the future.
