Zaburzenia wzrostu (karłowatość)
Leczenie

Leczenie zaburzeń wzrostu (karłowatości) wymaga indywidualizacji w zależności od etiologii. Podstawową terapią jest podawanie hormonu wzrostu (somatropina codziennie lub somatrogon cotygodniowo) u dzieci z niedoborem tego hormonu, zespołem Turnera, zespołem Pradera-Williego, przewlekłą chorobą nerek czy defektem genetycznym SHOX. Leczenie somatropiną prowadzi się do osiągnięcia docelowego wzrostu, monitorując potencjalne działania niepożądane, takie jak reakcje skórne, nadciśnienie wewnątrzczaszkowe, obrzęki czy złuszczenie głowy kości udowej (SCFE). W przypadku achondroplazji, najczęstszej dysplazji szkieletowej, stosuje się vosoritide (Voxzogo) – analog peptydu natriuretycznego typu C, który po roku terapii zwiększa wzrost średnio o 1,57 cm, działając na receptor NPR-B i hamując aktywność FGFR3. FDA zatwierdziła ten lek dla dzieci od 5 lat z otwartymi płytkami wzrostu, a od 2023 roku dla wszystkich dzieci z achondroplazją, co pozwala na wcześniejsze rozpoczęcie terapii i lepsze efekty wzrostowe.

Terapia zaburzeń wzrostu (karłowatość) – wprowadzenie

Leczenie zaburzeń wzrostu (karłowatości) obejmuje różne metody terapeutyczne, które zależą przede wszystkim od przyczyny leżącej u podstaw tego stanu. Główne podejścia terapeutyczne koncentrują się na zwiększeniu wzrostu poprzez terapię hormonalną, łagodzeniu objawów i powikłań związanych z karłowatością oraz poprawie jakości życia pacjentów. Należy podkreślić, że nie wszystkie rodzaje karłowatości mogą być skutecznie leczone tymi samymi metodami, a strategia leczenia musi być zindywidualizowana.12

Celem leczenia jest przede wszystkim utrzymanie niezależności pacjenta i poprawa jego funkcjonowania. Większość metod leczenia zaburzeń wzrostu nie zwiększa wzrostu, ale może korygować lub łagodzić problemy wynikające z powikłań związanych z tym stanem.12

Terapia hormonem wzrostu

Podstawową metodą leczenia zaburzeń wzrostu jest stosowanie hormonu wzrostu, który może zwiększyć ostateczny wzrost u dzieci z niedoborem tego hormonu. Jest to skuteczne leczenie w przypadku wielu różnych typów zaburzeń wzrostu, jednak nie jest zazwyczaj stosowane w leczeniu problemów związanych z rozwojem kości (takich jak achondroplazja i inne dysplazje szkieletowe).12

Dostępne preparaty hormonu wzrostu

Dostępne są różne preparaty hormonu wzrostu, w tym:1

  • Somatropina – podawana w codziennych iniekcjach, stosowana w leczeniu wielu przyczyn zaburzeń wzrostu
  • Somatrogon – podawany w iniekcjach cotygodniowych, stosowany tylko w przypadku niedoboru hormonu wzrostu

Narodowy Instytut Zdrowia i Doskonałości Klinicznej (NICE) zaleca leczenie somatropiną jako opcję dla dzieci, których słaby wzrost jest związany z:12

NICE zaleca również to leczenie dla dzieci, które urodziły się małe i nie nadrabiają wzrostu do 4 roku życia lub później.12

Sposób podawania i monitorowanie leczenia

Leczenie somatropiną powinno być rozpoczęte i monitorowane przez specjalistę w dziedzinie pediatrii z doświadczeniem w zarządzaniu zaburzeniami hormonu wzrostu u dzieci (endokrynologa dziecięcego). Hormon podawany jest w pojedynczej codziennej iniekcji, którą zwykle może wykonać rodzic, opiekun lub dziecko, gdy jest wystarczająco dorosłe.12

W przypadku dzieci z niedoborem hormonu wzrostu, leczenie prowadzone jest zazwyczaj przez wiele lat, aż do osiągnięcia maksymalnego wzrostu, często w zakresie przeciętnego wzrostu dorosłych w ich rodzinach.12

Skuteczność leczenia zależy od przyczyny zaburzeń wzrostu. Leczenie zwykle trwa do momentu zakończenia wzrostu dziecka lub osiągnięcia docelowego wzrostu. Dzieci z niedoborem hormonu wzrostu bardzo dobrze reagują na somatropinę i mogą osiągnąć względnie normalny wzrost dorosłego.12

Leczenie somatropiną może zostać zakończone po zakończeniu wzrostu dziecka, ale w niektórych przypadkach może być kontynuowane w dorosłości, ponieważ czasami pomaga zapobiegać problemom takim jak osteoporoza.12

Efekty uboczne terapii hormonalnej

Reakcje skórne są najczęściej zgłaszanym efektem ubocznym leczenia hormonem wzrostu. W bardzo rzadkich przypadkach leczenie jest związane z uporczywymi silnymi bólami głowy, wymiotami i problemami ze wzrokiem.1

Inne możliwe działania niepożądane obejmują:12

W przypadku tych powikłań zaleca się tymczasowe przerwanie terapii do momentu ustąpienia objawów i późniejsze wznowienie w niższych dawkach.1

Nowe metody leczenia achondroplazji

Vosoritide (Voxzogo)

W 2021 roku amerykańska Agencja ds. Żywności i Leków (FDA) zatwierdziła vosoritide, znany pod nazwą handlową Voxzogo, do poprawy wzrostu u dzieci z achondroplazją, najczęstszą formą karłowatości. Lek ten jest podawany w postaci zastrzyku dzieciom w wieku od 5 lat z achondroplazją, które mają otwarte płytki wzrostu, co umożliwia im dalszy wzrost.12

Vosoritide jest analogiem peptydu natriuretycznego typu C (CNP), który działa poprzez przyłączanie się do receptora zwanego receptorem peptydu natriuretycznego typu B (NPR-B) na powierzchni komórek. Aktywacja tego receptora zmniejsza aktywność FGFR3 (receptor czynnika wzrostu fibroblastów 3), stymulując w ten sposób normalny wzrost kości i poprawiając objawy choroby.1

W badaniach klinicznych osoby, które przyjmowały Voxzogo, wykazywały statystycznie istotną poprawę wzrostu w porównaniu do placebo, zyskując średnio 1,57 cm wzrostu po roku leczenia. Zaobserwowany wzrost następował proporcjonalnie zarówno w kręgosłupie, jak i w kończynach dolnych.12

Dane z dłuższych obserwacji sugerują, że poprawa wzrostu utrzymuje się w czasie. W badaniach osoby przyjmujące Voxzogo rosły średnio o 0,6 cala (1,6 cm) więcej niż bez leczenia.12

Pod koniec 2023 roku FDA rozszerzyła zatwierdzenie leku na dzieci w każdym wieku z achondroplazją z otwartymi płytkami wzrostu. Wcześniejsze rozpoczęcie leczenia oznacza większą szansę na osiągnięcie potencjału wzrostowego.1

Mechanizm działania vosoritide

Vosoritide wpływa na wzrost liniowy poprzez oddziaływanie na płytki wzrostu kości endochondralnej – głównie kości długich. Wstępne dane wskazują, że wcześniejsze leczenie poprawia proporcjonalny wzrost kończyn, zmniejszając jednocześnie kifozę piersiowo-lędźwiową kręgosłupa i szpotawość kolan.1

Celem stosowania Voxzogo jest poprawa wzrostu liniowego lub wysokości u pacjentów, co pozwala im na normalne, niezależne codzienne funkcjonowanie.12

Obecnie trwają badania nad opracowaniem preparatów podskórnych o dłuższym działaniu oraz innych substancji, które można przyjmować doustnie w leczeniu achondroplazji.1

Infigratinib i inne nowe terapie

Infigratinib, doustny inhibitor FGFR, jest obecnie badany w próbach klinicznych pod kątem poprawy prędkości wzrostu i rozwoju kości. Badania wykazały, że lek zwiększa szybkość wzrostu o średnio 2,5 cm rocznie w trakcie 18-miesięcznego okresu leczenia. Infigratinib nie tylko wspomaga wzrost kości, ale także poprawia proporcjonalność górnych i dolnych segmentów ciała.12

Oprócz vosoritide i infigratinibu badane są również inne eksperymentalne terapie:12

  • Recifercept – kolejny lek ukierunkowany na szlak FGFR3
  • TransCon CNP – podawany w iniekcjach cotygodniowych zamiast codziennych, co stanowi przełom w terapii achondroplazji
  • Terapie genowe – będące w początkowej fazie badań

Terapia genowa w leczeniu zaburzeń wzrostu

Obiecującym kierunkiem rozwoju terapii jest leczenie genowe. Badacze z NUS Yong Loo Lin School of Medicine wykazali, że terapia genowa wykorzystująca jednodawkowe wstrzyknięcie wirusa zawierającego prawidłowy gen może potencjalnie wyleczyć karłowatość oporną na hormon wzrostu, znaną również jako zespół Larona.1

Zespół próbował zwiększyć poziom hormonu zwanego insulinopodobnym czynnikiem wzrostu 1 (IGF1) poprzez zastąpienie wadliwego genu receptora hormonu wzrostu za pomocą wirusa zawierającego instrukcje specjalnie ukierunkowane na wątrobę. Wyniki wykazały znaczący wzrost wielkości i masy ciała w porównaniu z nieleczonym modelem laboratoryjnym.1

Badania innych naukowców wykazały, że ekspresja genów może utrzymywać się do 10 lat po pojedynczej dawce wektora AAV (wirus związany z adenowirusem), co czyni terapię genową AAV atrakcyjną metodą leczenia z potencjalnie bardzo dobrymi wynikami terapeutycznymi.1

Leczenie chirurgiczne zaburzeń wzrostu

Wydłużanie kończyn

W przypadku osób z wyjątkowo krótkimi nogami, proces wydłużania kończyn znany jako dystrakcja może być opcją terapeutyczną. Metoda ta polega na przecięciu kości nogi i umocowaniu jej do specjalnej ramy. Kończyna jest następnie stopniowo rozciągana, umożliwiając tworzenie się nowej kości pomiędzy dwoma przerwanymi końcami kości.12

Z czasem ta kość staje się silniejsza, aż będzie w stanie utrzymać ciężar ciała. Dystrakcja może czasami prowadzić do znacznego zwiększenia wzrostu, ale jest to długotrwałe leczenie i wiąże się z ryzykiem powikłań, dlatego nie zawsze jest zalecane.12

Niektóre osoby odczuwają ból podczas lub po zabiegu wydłużania kończyn. Inne możliwe powikłania obejmują:1

  • Złe formowanie się kości
  • Złamania
  • Infekcje
  • Niewłaściwe tempo wydłużania kości
  • Zakrzepy krwi

Istnieją również wątpliwości co do bezpieczeństwa i skuteczności tej procedury. Dlatego ważne jest, aby dokładnie zrozumieć, co to leczenie obejmuje, i omówić ryzyko z chirurgiem lub lekarzem, jeśli jest sugerowane jako możliwe leczenie dla pacjenta lub jego dziecka.12

Inne procedury chirurgiczne

W przypadku pacjentów z dysplazją szkieletową, taką jak achondroplazja, leczenie zazwyczaj ma na celu łagodzenie innych objawów, a nie zwiększanie wzrostu. Procedury chirurgiczne, które mogą korygować problemy u osób z nieproporcjonalną karłowatością, obejmują:12

  • Korygowanie kierunku, w którym rosną kości
  • Stabilizację i korygowanie kształtu kręgosłupa
  • Zwiększanie rozmiaru otwarcia w kościach kręgosłupa (kręgach), aby złagodzić ucisk na rdzeń kręgowy
  • Umieszczanie zastawki w celu usunięcia nadmiaru płynu wokół mózgu (wodogłowie), jeśli występuje
  • Prostowanie nóg „O” (szpotawych)

W zależności od specyficznych problemów pacjenta, leczenie chirurgiczne może obejmować:1

  • Dekompresję podpotyliczną w celu złagodzenia ucisku na ośrodki oddechowe i nerwy
  • Osteotomię derotacyjną lub zastosowanie płytki 8-kształtnej w przypadku bólu kończyn lub obserwowanej bocznej siły nacisku
  • Tlenoterapię lub dekompresję szyjną w leczeniu kompresji otworu wielkiego

Leczenie skojarzone i multidyscyplinarne

Ponieważ zaburzenia wzrostu mogą wiązać się z wieloma powiązanymi schorzeniami i problemami, dzieci i dorośli dotknięci tymi zaburzeniami są objęci opieką multidyscyplinarnego zespołu specjalistów medycznych.12

Pacjenci mogą mieć regularne kontrole u członków zespołu terapeutycznego, aby monitorować ich stan zdrowia i leczyć wszelkie pojawiające się problemy. Leczenie, którego mogą potrzebować, obejmuje:1

  • Fizjoterapię – dla problemów z ruchem i bólem, wzmacnianie mięśni i zwiększanie zakresu ruchu stawów
  • Ortodoncję – dla problemów z zębami
  • Leczenie infekcji ucha i bezdechu sennego – w tym adenoidektomię i/lub tonsilektomię, stosowanie urządzeń CPAP lub BiPAP
  • Poradnictwo dietetyczne i ćwiczenia – aby zapobiegać otyłości, która może pogorszyć problemy szkieletowe

Dodatkowe terapie hormonalne

W przypadku dziewcząt z zespołem Turnera, oprócz hormonu wzrostu, leczenie wymaga również terapii estrogenowej i pokrewnymi hormonami, aby rozpocząć dojrzewanie i prowadzić do rozwoju płciowego dorosłych. Terapia zastępcza estrogenami zwykle trwa do czasu osiągnięcia przeciętnego wieku menopauzy.12

W niektórych przypadkach stosowane są również analogii gonadoliberyny (GnRH) w celu zatrzymania progresji przedwczesnego dojrzewania płciowego.12

Leczenie insulinopodobnym czynnikiem wzrostu (IGF-1)

W 2007 roku Europejska Agencja Leków (EMEA) zatwierdziła stosowanie rekombinowanego (rh) IGF-1 (mecaserminu) w leczeniu karłowatości w ciężkim pierwotnym niedoborze IGF-1. Leczenie IGF-1 jest jedyną skuteczną opcją terapeutyczną w takich przypadkach.1

Doświadczenia z leczeniem rhIGF-1 w przypadku karłowatości w ciężkim pierwotnym niedoborze IGF-1 sięgają wczesnych lat 90. Wyniki dotyczące wzrostu w krótkim i długim okresie (4-7 lat) są niezwykle spójne.1

U dzieci z ciężkim pierwotnym niedoborem IGF-1 (rzadkim schorzeniem o częstości występowania mniejszej niż 1:10 000), rokowanie co do ostatecznego wzrostu jest bardzo złe (ok. 130 cm), a terapia IGF-1 jest właściwą formą leczenia opartego na patofizjologii. Podskórne podawanie IGF-1 dwa razy dziennie w dawkach 80-120 μg/kg przyspiesza wzrost i zwiększa końcowy wzrost o 12-15 cm, według aktualnych danych.1

Przyszłość leczenia zaburzeń wzrostu

Badania nad nowymi metodami leczenia zaburzeń wzrostu są kontynuowane, a naukowcy pracują nad:

  • Preparatami o dłuższym działaniu, wymagającymi rzadszego podawania1
  • Lekami doustnymi jako alternatywą dla iniekcji1
  • Terapiami genowymi, które mogłyby trwale skorygować przyczynę zaburzeń wzrostu1
  • Spersonalizowanym podejściem terapeutycznym, uwzględniającym konkretne przyczyny i objawy zaburzeń wzrostu u danego pacjenta1

Leczenie zaburzeń wzrostu – podsumowanie

Leczenie zaburzeń wzrostu (karłowatości) wymaga indywidualnego podejścia, opartego na konkretnej przyczynie i potrzebach pacjenta. Obecnie dostępne metody terapeutyczne obejmują:

  • Terapię hormonem wzrostu – najskuteczniejszą w przypadku niedoboru hormonu wzrostu, ale nieskuteczną w dysplazjach szkieletowych12
  • Nowe leki celowane – takie jak vosoritide (Voxzogo) dla pacjentów z achondroplazją, działające na poziomie molekularnym12
  • Leczenie chirurgiczne – zarówno wydłużanie kończyn, jak i korekcje deformacji szkieletowych12
  • Terapię IGF-1 – w przypadku pierwotnego niedoboru insulinopodobnego czynnika wzrostu1
  • Leczenie skojarzone – łączące różne metody terapeutyczne oraz opiekę multidyscyplinarnego zespołu specjalistów12

Podjęcie decyzji o leczeniu powinno uwzględniać potencjalne korzyści i ryzyko, a także preferencje pacjenta i jego rodziny. Ważne jest również, aby osoby z zaburzeniami wzrostu miały dostęp do regularnych kontroli i opieki specjalistycznej, co może znacząco poprawić jakość ich życia.12

  • #1 Restricted growth (dwarfism)
    https://www.nhs.uk/conditions/restricted-growth/
    The main treatment for restricted growth is growth hormone medicine. […] Surgery to increase the length of your arms or legs is sometimes done, but this is rare. […] Growth hormone is used to increase height in children with restricted growth, or children who are not growing as expected for their age. […] It can treat many different types of restricted growth, but it is not normally used to treat a problem with bone development (such as achondroplasia and other skeletal dysplasias). […] Growth hormone medicines include: somatropin a daily injection used to treat many causes of restricted growth, somatrogon a weekly injection, only used if you have a lack of growth hormone (growth hormone deficiency). […] How well treatment works depends on what’s causing the restricted growth. Treatment usually continues until your child stops growing or reaches their target height.
  • #1 Dwarfism – Diagnosis and treatment – Mayo Clinic
    https://www.mayoclinic.org/diseases-conditions/dwarfism/diagnosis-treatment/drc-20371975
    The goal of treatment is to keep you doing what you want to do independently. Most dwarfism treatments don’t increase stature, but they may correct or ease problems caused by complications. […] In 2021, the U.S. Food and Drug Administration (FDA) approved vosoritide, known by the brand name Voxzogo, to improve growth in children who have the most common type of dwarfism. Given as a shot, this medicine is for children 5 years of age and older who have achondroplasia and open growth plates so they can still grow. In studies, those who took Voxzogo grew an average of 0.6 inches (1.6 cm). Ask your doctor and geneticist about the potential risks and benefits. […] For people with dwarfism due to low levels of growth hormones, treatment with shots of a synthetic version of the hormone may increase final height. In most cases, children receive daily shots for several years until they reach a maximum adult height often within the average adult range for their families.

    Some people with restricted growth (dwarfism) may be able to have growth hormone treatment or leg-lengthening surgery. […] The National Institute for Health and Care Excellence (NICE) recommends a human growth hormone treatment called somatropin as an option for children whose poor growth is linked to: growth hormone deficiency, Turner syndrome, Prader-Willi syndrome, chronic kidney disease, a genetic condition called SHOX deficiency. […] NICE also recommends it for some children who are born small and fail to catch up in growth by the age of 4 or later. […] Somatropin treatment should be started and monitored by a child health specialist with expertise in managing growth hormone disorders in children (paediatric endocrinologist). […] The hormone is given as a single daily injection, which can usually be done by a parent, carer, or by the child when they’re old enough.

    Skin reactions are the most commonly reported side effect. In very rare cases, the treatment is associated with persistent severe headaches, vomiting and vision problems. […] Children with growth hormone deficiency respond very well to somatropin and may be able to reach a relatively normal adult height. The effectiveness in children with other conditions can vary. […] Somatropin treatment may stop once your child stops growing, but in some cases it may be given into adulthood because it can sometimes help prevent problems such as weak bones (osteoporosis). […] NICE also recommends a growth hormone treatment called somatrogon for children and young people aged 3 to 17 years old with poor growth caused by growth hormone deficiency. […] It works in a similar way to somatropin but is given as a weekly injection instead of a daily one.

    The normal variants of short stature can expect to lead healthy lives. The patients suffering from GHD can benefit from recombinant human growth hormone therapy and generally attain heights similar to their parents, given that the treatment is commenced before puberty. […] Short stature may be an indicator of chronic occult disease and need a thorough workup. […] The complications which are associated with GH therapy are- possible predisposition to type-2 diabetes, benign intracranial hypertension, edema/carpal tunnel syndrome, slipped capital femoral epiphysis (SCFE), scoliosis, prepubertal gynecomastia. Management of these complications can be done by temporary therapy termination until resolving symptoms and restarting later at lower doses.
  • #1 New treatment for people with dwarfism | European Medicines Agency (EMA)
    https://www.ema.europa.eu/en/news/new-treatment-people-dwarfism
    EMA has recommended granting a marketing authorisation in the European Union (EU) for Voxzogo (vosoritide) for the treatment of achondroplasia, a condition that impairs bone growth and causes dwarfism. The medicine is intended for use in patients 2 years and older whose epiphyses (growth plates of the bones) are not yet closed. […] In patients with achondroplasia the fibroblast growth-factor receptor 3 (FGFR3) gene is permanently switched on, preventing normal bone growth. Vosoritide, the active substance in Voxzogo, works by attaching to a receptor called natriuretic peptide receptor type B (NPR-B) on the surface of cells. The activation of this receptor will reduce the activity of FGFR3 and thereby stimulate the normal growth of bones and improve the symptoms of the disease. […] During the course of the study, a statistically significant improvement in growth was observed in patients treated with vosoritide compared to placebo, adding an average 1.57 cm in height after a year of treatment. The observed increase in growth occurred proportionally in both the spine and the lower limbs. Longer-term data in number of patients suggest that the improved growth is maintained. A separate ongoing study including subjects aged 2 to 5 also suggests consistent improvement in growth.
  • #1 FDA approval grows use of growth therapy for children with achondroplasia  – CHOC Pediatrica
    https://care.choc.org/fda-approval-grows-use-of-growth-therapy-for-children-with-achondroplasia/
    The most common type of dwarfism, achondroplasia can now be treated with Voxzogo starting at birth, maximizing children’s growth potential. […] In November 2021, the FDA approved Voxzogo (vosoritide) to assist with linear growth in children ages 5 and older with achondroplasia whose growth plate remained open. At the end of 2023, the FDA extended approval to children of all ages with achondroplasia with open growth plates. […] Starting earlier, then, signifies a large step toward helping children with achondroplasia reach their growth potential. […] After a child receives a diagnosis of achondroplasia, the newly updated approval permits them to begin a regimen of Voxzogo at any age. Administered daily via subcutaneous injection, Voxzogo affects linear growth by working on the growth plates of the endochondral bone — primarily long bones.

    Exciting as these numbers are, Dr. Bhangoo has treated patients who experienced substantially more improvement. […] To keep the growth plates open as long as possible, pediatric endocrinologists prescribe aromatase inhibitors. […] The goal of Voxzogo use is improved linear growth or height in patients that permits them to engage in normal, independent daily living. […] Thus far, clinicians have reported each of these improvements at various times. Preliminary data indicates that earlier treatment improves proportionate growth of the extremities while reducing spinal thoracolumbar kyphosis and genu varum. […] There is continual work to develop longer-acting subcutaneous formulation and other agents that can be taken orally for treatment of achondroplasia.

    Clinical trials have demonstrated that Voxzogo significantly increases growth velocity, leading to improved height outcomes in children with achondroplasia. […] Limb-lengthening surgery is an invasive procedure aimed at increasing limb length and overall stature in individuals with achondroplasia. […] Although effective in significantly increasing height, limb-lengthening surgery carries risks such as infection, nerve damage, and prolonged recovery periods. […] Growth hormone therapy has been utilized off-label to attempt to improve growth velocity in children with achondroplasia. […] However, clinical evidence supporting its efficacy is limited and inconsistent. […] Several experimental treatments are currently under clinical investigation for achondroplasia. Infigratinib, an oral FGFR inhibitor, is undergoing clinical trials to assess its potential to improve growth velocity and bone development.

    https://www.drugtargetreview.com/news/103053/gene-therapy-a-potential-cure-for-growth-hormone-resistant-dwarfism/
    Researchers have shown that gene therapy using a single-dose injection of a virus carrying the good gene could possibly be used to cure growth-hormone resistant dwarfism. […] A new study from the NUS Yong Loo Lin School of Medicine (NUS Medicine), Singapore has shown that gene therapy using a single-dose injection of a virus carrying the good gene can potentially be used to cure growth-hormone resistant dwarfism, also known as Laron Syndrome. […] The team attempted to increase a hormone called insulin-like-growth factor 1 (IGF1) in a laboratory model by replacing the defective growth hormone receptor gene, using a virus containing instructions specifically targeted at the liver. […] The results showed the significant size and weight which increased steadily throughout the course of 26 weeks, in comparison to the untreated laboratory model.

    https://www.drugtargetreview.com/news/103053/gene-therapy-a-potential-cure-for-growth-hormone-resistant-dwarfism/
    Other researchers have shown that there is persistent gene expression for up to 10 years to produce proteins in the liver necessary for growth, following a single dose of AAV administration. This makes AAV gene therapy an attractive treatment with potentially significantly good therapy outcomes. […] With these optimistic results, the AAV vector can be potentially used to treat people with Laron syndrome. […] Gene therapy has given us a promising start in managing dwarfism. This is far more favourable compared to rhIGF1 injections, once or twice daily for many years, which causes side effects of pain and discomfort to patients and comes as a huge financial burden to those involved, concluded Professor Lee K O, research lead.

    Common side effects of somatrogon include headaches, a high temperature and anaemia. It may not be a suitable treatment for all children. A child health specialist will advise you. […] If you have particularly short legs, a leg-lengthening process known as distraction may be an option. […] Using surgery, the leg bone is broken and fixed to a special frame. With the support of the frame, the leg is stretched, allowing new bone to form in between the two broken ends of bone. […] Over time, this bone gets stronger until it’s able to support your weight. […] Distraction can sometimes result in a significant increase in height, but it’s a lengthy treatment and has a risk of complications, so isn’t always recommended. […] Some people have pain during or after the limb-lengthening procedure.

    https://newtonschemist.co.uk/nhs_conditions_restricted-growth_treatment
    Other possible complications include: poor bone formation, fracture, infection, bone lengthening at an inappropriate rate, blood clots. […] There’s also some uncertainty about the safety and effectiveness of the procedure. […] It’s therefore important that you understand exactly what it involves and talk to your surgeon or doctor about the risks if it’s suggested as a possible treatment for you or your child. […] As restricted growth can be associated with several related conditions and problems, affected children and adults will be cared for by a multidisciplinary team of healthcare professionals. […] You may have regular check-ups with members of your care team so your health can be monitored and any problems that develop can be treated.

    Treatment for girls with Turner syndrome also requires estrogen and related hormone therapy to start puberty and lead to adult sexual development. Estrogen replacement therapy usually continues until the average age of menopause. […] Surgical procedures that may correct problems in people with disproportionate dwarfism include: Correcting the direction the bones grow in. Stabilizing and correcting the shape of the spine. Increasing the size of the opening in bones of the spine, called vertebrae, to ease pressure on the spinal cord. Placing a shunt to remove too much fluid around the brain also known as hydrocephalus if it occurs. […] Some people with dwarfism choose to undergo surgery called extended limb lengthening. This procedure is controversial because there are risks. Those with dwarfism are urged to wait to decide about limb lengthening until they’re old enough to participate in the decision. This approach is recommended because of the emotional and physical stress involved with multiple procedures. […] Regular checkups and ongoing care by a healthcare professional familiar with dwarfism can make quality of life better. Because there is a range of symptoms and complications, conditions are managed as they happen, such as tests and treatment for ear infections, spinal stenosis or sleep apnea.

    Surgical intervention is typically not necessary but may be needed if the patient experiences extremity pain or if a lateral thrust is observed. Surgery should be performed by an orthopaedic doctor that specializes in skeletal dysplasia and may include derotational osteotomy or 8-plate. […] If treatment is required, a subocciptal decompression is necessary to relieve the compression of the respiratory centers and nerves. […] Treatment can include oxygen supplementation (used in a small percentage of patients) or a cervical decompression to treat foramen magnum compression. […] If serious obstructive sleep apnea is suspected, then polysomnography should be obtained for further information. There are several options for treatment, depending on the severity of the apnea: Adenoidectomy and/or tonsillectomy, CPAP machine use, BIPAP machine use.

    There are various treatment options available to these kids to achieve the best possible outcomes for them. These includes: […] Recombinant human growth hormone therapy (rhGH) is an effective treatment for patients suffering from growth hormone deficiency. Early intervention can prevent short stature and the psychosocial stress associated with it. […] For patients with idiopathic short stature (ISS), commencing GH therapy can enhance the growth velocity and mean adult height. […] Gonadotropin-releasing hormone (GnRH) analogs are used to halt the progression of precocious puberty. […] Brain tumors need neurosurgery intervention. The limb-lengthening procedures are not recommended as they have high morbidity and mortality. […] The child receives daily subcutaneous growth hormone (GH) injections, and are advised to take GH injections regularly, preferably within 1 hour of sleep every night, at a specific time, and not to miss more than one dose a month.

    In 2007 the European Medicines Agency (EMEA) licensed the use of recombinant (rh) IGF-1 (mecasermin) for the treatment of dwarfism in severe primary IGF-1 deficiency. […] Treatment with IGF-1 is the only effective therapeutic option in such cases. […] Experiences with treatment with rhIGF-1 for dwarfism in severe primary IGF-1 deficiency date back to the early 1990s. […] The results with regard to growth in the short term and long term (47 years) are remarkably consistent. […] Replacement therapy with IGF-1 in children with severe primary IGF-1 deficiencywhich is rare, with a prevalence of 1:10 000is the pathophysiologically correct form of treatment, for which there is currently no alternative. […] The treatment has been found to be relatively safe for patients, even though they have to be treated over many years.

    https://pmc.ncbi.nlm.nih.gov/articles/PMC2780013/
    The growth hormone-IGF (insulin-like growth factor) system plays a central role in hormonal growth regulation. Recombinant human (rh) growth hormone (GH) has been available since the late 1980s for replacement therapy in GH-deficient patients and for the stimulation of growth in patients with short stature of various causes. Growth promotion by GH occurs in part indirectly through the induction of IGF-1 synthesis. In primary disturbances of IGF-1 production, short stature can only be treated with recombinant human IGF-1 (rhIGF-1). rhIGF-1 was recently approved for this indication but can also be used to treat other conditions. […] In children with severe primary IGF-1 deficiency (a rare condition whose prevalence is less than 1:10 000), the prognosis for final height is very poor (ca. 130 cm), and IGF-1 therapy is the appropriate form of pathophysiologically based treatment. There is no alternative treatment at present. The subcutaneous administration of IGF-1 twice daily in doses of 80 to 120 g/kg accelerates growth and increases final height by 12 to 15 cm, according to current data.

    Dwarfism in itself is not a disease that needs a 'cure’. It is a condition which in some cases may be caused by a disease, so sometimes treatments may be needed. […] For most people with dwarfism, treatment for growth itself is not possible or helpful. Most people will adapt their way of life to cope with their less than average height, but otherwise lead entirely normal lives. […] Treatment that might be relevant includes: […] This is treatment with a hormone medicine which aims to replace the growth hormone normally produced by the body. This is only helpful in a few specific causes of dwarfism where the lack of growth is caused by a lack of growth hormone. It is not helpful for people with achondroplasia. It is a treatment recommended by and managed by a specialist doctor. […] Rarely, an operation may be done to lengthen the bones of the legs. This is not commonly done as it involves breaking the leg bones and is a lengthy treatment with a number of risks.

    Treatment for restricted growth may include growth hormone injections, which can help a child with the condition grow more than they otherwise would. […] In cases of DSS where the legs are particularly short, a leg-lengthening procedure is sometimes used, but there’s some uncertainty about its safety and effectiveness. […] Some people with restricted growth (dwarfism) may be able to have growth hormone treatment or leg-lengthening surgery. […] The National Institute for Health and Care Excellence (NICE) recommends human growth hormone treatment (somatropin) as an option for children whose poor growth is linked to growth hormone deficiency, Turner syndrome, Prader-Willi syndrome, chronic kidney disease, or a genetic condition called SHOX deficiency. […] Somatropin treatment should be started and monitored by a child health specialist with expertise in managing growth hormone disorders in children (paediatric endocrinologist).

Starting this treatment early can help prevent them from being much shorter than their peers and dealing with the mental stress that can come with it. […] Gonadotropin-releasing hormone (GnRH) analogs are used to stop the progress of early-onset puberty. […] Hormone therapy to help kids grow can sometimes have complications, such as the potential for developing type-2 diabetes, benign pressure increase in the skull, water retention or carpal tunnel syndrome, displacement of the growth plate in the hip joint, scoliosis, and swelling of the breast tissue in boys before puberty begins.

    EMA has recommended granting a marketing authorisation in the European Union (EU) for Voxzogo (vosoritide) for the treatment of achondroplasia, a condition that impairs bone growth and causes dwarfism. The medicine is intended for use in patients 2 years and older whose epiphyses (growth plates of the bones) are not yet closed. […] In patients with achondroplasia the fibroblast growth-factor receptor 3 (FGFR3) gene is permanently switched on, preventing normal bone growth. Vosoritide, the active substance in Voxzogo, works by attaching to a receptor called natriuretic peptide receptor type B (NPR-B) on the surface of cells. The activation of this receptor will reduce the activity of FGFR3 and thereby stimulate the normal growth of bones and improve the symptoms of the disease. […] During the course of the study, a statistically significant improvement in growth was observed in patients treated with vosoritide compared to placebo, adding an average 1.57 cm in height after a year of treatment. The observed increase in growth occurred proportionally in both the spine and the lower limbs. Longer-term data in number of patients suggest that the improved growth is maintained. A separate ongoing study including subjects aged 2 to 5 also suggests consistent improvement in growth.
