Choroba kawasakiego
Zapobieganie i profilaktyka

Choroba Kawasakiego to zapalenie naczyń średniego kalibru, z istotnym ryzykiem rozwoju tętniaków tętnic wieńcowych, które mogą prowadzić do nagłej śmierci sercowej. Etiologia pozostaje nieznana, co uniemożliwia profilaktykę pierwotną. Epidemiologiczne dane z okresu pandemii COVID-19 wskazują na około 40% spadek zachorowań po wprowadzeniu środków zapobiegających transmisji SARS-CoV-2, co sugeruje udział czynników zakaźnych w patogenezie. Wczesna diagnostyka i leczenie w ciągu pierwszych 10 dni od wystąpienia gorączki znacząco redukują ryzyko powikłań sercowo-naczyniowych – zmniejszając częstość zmian w tętnicach wieńcowych z 25% do poniżej 5% oraz śmiertelność z 1% do 0,17%.

Profilaktyka Choroby Kawasakiego

Choroba Kawasakiego (Kawasaki disease) jest rzadkim schorzeniem, które charakteryzuje się zapaleniem naczyń krwionośnych średniej wielkości w organizmie. Szczególnie niebezpieczne jest zajęcie tętnic wieńcowych, które może prowadzić do rozwoju tętniaków tętnic wieńcowych, a w konsekwencji do nagłej śmierci sercowej. Obecnie choroba Kawasakiego stanowi główną przyczynę nabytych chorób serca u dzieci w krajach rozwiniętych.1

Brak skutecznej profilaktyki pierwotnej

Aktualnie nie istnieją potwierdzone metody zapobiegania chorobie Kawasakiego. Wynika to z faktu, że etiologia schorzenia pozostaje nieznana, co uniemożliwia opracowanie skutecznych strategii profilaktyki pierwotnej.123 Oficjalne stanowiska wielu instytucji zdrowotnych wyraźnie podkreślają ten fakt:456

  • Obecnie nie są znane środki zapobiegawcze dla tej choroby
  • Nie można zapobiec chorobie Kawasakiego, ponieważ jej przyczyna jest nieznana
  • W chwili obecnej nie ma sprawdzonych środków zapobiegawczych dla choroby Kawasakiego

Obserwacje epidemiologiczne podczas pandemii COVID-19

Interesujących danych dotyczących potencjalnych czynników wyzwalających chorobę Kawasakiego dostarczyły obserwacje epidemiologiczne z okresu pandemii COVID-19. W Korei Południowej odnotowano znaczący spadek zachorowań na chorobę Kawasakiego podczas stosowania szeroko zakrojonych środków zapobiegających transmisji SARS-CoV-2.9 Liczba przypadków choroby Kawasakiego zmniejszyła się o około 40% po wprowadzeniu środków zapobiegawczych przeciwko COVID-19 w lutym 2020 roku.10

Badacze sugerują, że obserwowany spadek zachorowań na chorobę Kawasakiego mógł być związany z:911

  • Noszeniem maseczek ochronnych
  • Regularnym myciem rąk
  • Zamknięciem szkół
  • Zachowywaniem dystansu fizycznego
  • Obniżonym poziomem zanieczyszczenia powietrza
  • Ograniczonym rozprzestrzenianiem się infekcji dróg oddechowych

12

Te obserwacje dostarczają nowych dowodów epidemiologicznych na poparcie tezy, że choroba Kawasakiego może być wywoływana przez czynniki zakaźne. Jak zauważył jeden z badaczy: „W czasie pandemii COVID dzieci były narażone na mniej wirusów i innych czynników zakaźnych. Ten 'naturalny eksperyment’, który miał miejsce w wyniku izolacji i noszenia maseczek przez dzieci, potwierdza prawdopodobieństwo, że choroba Kawasakiego jest wyzwalana przez wirusy lub inne czynniki zakaźne w środowisku.”13

Profilaktyka wtórna i zapobieganie powikłaniom sercowo-naczyniowym

Chociaż nie można zapobiec wystąpieniu choroby Kawasakiego, istnieją skuteczne strategie zapobiegania powikłaniom sercowo-naczyniowym, które stanowią główne ryzyko związane z tym schorzeniem. Bez odpowiedniego leczenia tętniaki tętnic wieńcowych rozwijają się u około 15-25% pacjentów z chorobą Kawasakiego.114

Wczesna diagnostyka i leczenie

Najważniejszym elementem zapobiegania powikłaniom sercowo-naczyniowym w chorobie Kawasakiego jest wczesna diagnostyka i niezwłoczne wdrożenie odpowiedniego leczenia.152 Rozpoczęcie terapii w ciągu pierwszych 10 dni od wystąpienia gorączki znacząco zmniejsza ryzyko uszkodzenia tętnic wieńcowych.1516

Korzyści z wczesnego wdrożenia leczenia obejmują:1718

  • Zmniejszenie ryzyka zmian w tętnicach wieńcowych z 25% do mniej niż 5%
  • Obniżenie śmiertelności z 1% do 0,17%
  • Szybsze ustąpienie objawów klinicznych

1419

Standardowe strategie terapeutyczne w profilaktyce powikłań

Podstawowymi metodami leczenia choroby Kawasakiego, które jednocześnie stanowią profilaktykę powikłań sercowo-naczyniowych, są:2014

Immunoglobulina dożylna (IVIG)

Immunoglobulina dożylna (IVIG) stanowi podstawowy element leczenia choroby Kawasakiego i powinna być podana jak najszybciej po rozpoznaniu choroby, najlepiej w ciągu pierwszych 10 dni od wystąpienia gorączki.1 Standardowa dawka IVIG wynosi 2 g/kg masy ciała w pojedynczej infuzji.16

Mechanizm działania IVIG w profilaktyce powikłań sercowo-naczyniowych:2122

  • Zmniejsza stan zapalny w naczyniach krwionośnych
  • Obniża ryzyko rozwoju zmian w tętnicach wieńcowych
  • Przyspiesza ustąpienie gorączki i innych objawów klinicznych

23

Istotną informacją dla lekarzy jest to, że podanie IVIG ma wpływ na późniejsze szczepienia. Zgodnie z zaleceniami Amerykańskiej Akademii Pediatrii, żywe szczepionki wirusowe (np. MMR, ospa wietrzna) powinny być odroczone o 11 miesięcy po podaniu IVIG w leczeniu choroby Kawasakiego, ponieważ immunoglobulina może wpływać na skuteczność tych szczepionek.242523

Kwas acetylosalicylowy (aspiryna)

Kwas acetylosalicylowy (ASA) jest drugim podstawowym lekiem stosowanym w terapii choroby Kawasakiego, chociaż jego rola w zapobieganiu zmianom w tętnicach wieńcowych jest mniej jednoznacznie udokumentowana niż w przypadku IVIG.2627

Stosowanie aspiryny w chorobie Kawasakiego obejmuje dwa etapy:28

  1. Faza ostra (działanie przeciwzapalne): wysokie dawki aspiryny (80-100 mg/kg/dobę w 4 dawkach podzielonych) są podawane wraz z IVIG do czasu ustąpienia gorączki. Niektóre ośrodki stosują dawki umiarkowane (30-50 mg/kg/dobę), które również są skuteczne.2930
  2. Faza przewlekła (działanie przeciwpłytkowe): po ustąpieniu gorączki dawka aspiryny jest zmniejszana do 3-5 mg/kg/dobę i kontynuowana przez co najmniej 6-8 tygodni od początku choroby, jeśli nie występują nieprawidłowości w tętnicach wieńcowych, lub bezterminowo, jeśli takie nieprawidłowości są obecne.2831

Warto podkreślić, że według ostatnich badań stosowanie niskich dawek ASA w ostrej fazie choroby Kawasakiego w połączeniu z IVIG nie jest gorsze niż stosowanie wysokich dawek ASA w zakresie zmniejszania ryzyka nieprawidłowości w tętnicach wieńcowych.26 Badania nie wykazały również, że dawki 30-50 mg/kg/dobę są lepsze niż 20-29 mg/kg/dobę.30

Ważne informacje dla lekarzy dotyczące stosowania aspiryny:32

  • Należy unikać stosowania ibuprofenu i innych niesteroidowych leków przeciwzapalnych (NLPZ) u pacjentów przyjmujących ASA z powodu antagonistycznego działania na efekt przeciwpłytkowy aspiryny
  • U pacjentów z dużymi lub olbrzymimi tętniakami oraz z niedawną historią zakrzepicy tętnic wieńcowych można rozważyć terapię potrójną: leki przeciwpłytkowe, drugi lek przeciwpłytkowy i antykoagulacja
  • Typowo dzieci nie powinny otrzymywać aspiryny, jednak w przypadku choroby Kawasakiego jest ona niezbędna i korzystna15

Leczenie uzupełniające w profilaktyce powikłań

W przypadku pacjentów z wysokim ryzykiem oporności na IVIG lub rozwoju tętniaków tętnic wieńcowych rozważa się dodatkowe strategie terapeutyczne:2429

Glikokortykosteroidy

Zastosowanie glikokortykosteroidów jako leczenia uzupełniającego do standardowej terapii IVIG i ASA jest zalecane u pacjentów z wysokim ryzykiem oporności na IVIG lub rozwoju tętniaków tętnic wieńcowych.33 Badanie RAISE wykazało korzyści z dodatkowej terapii kortykosteroidami u pacjentów z przewidywaną opornością na IVIG w początkowym leczeniu choroby Kawasakiego.33

Trwające badanie kliniczne KD-CAAP (Kawasaki Disease Coronary Artery Aneurysm Prevention) ma na celu ocenę skuteczności dodania steroidów do standardowego leczenia u dzieci z chorobą Kawasakiego w zapobieganiu tętniakom tętnic wieńcowych.3435

Cyklosporyna

W badaniu z 2019 roku wykazano, że cyklosporyna w połączeniu z IVIG może hamować rozwój nieprawidłowości w tętnicach wieńcowych.36 Cyklosporyna działa na warianty genetyczne związane z chorobą Kawasakiego i jej następstwami, co czyni ją kandydatem do terapii, szczególnie u dzieci z wysokim ryzykiem braku odpowiedzi na samo IVIG.37

W badaniu klinicznym całkowita częstość występowania nieprawidłowości w tętnicach wieńcowych była niższa w grupie otrzymującej cyklosporynę (14% vs 31%), jednak występowanie tych nieprawidłowości po 12 tygodniach nie różniło się istotnie statystycznie.37

Infliximab

Infliximab, przeciwciało monoklonalne działające na układ immunologiczny, jest stosowany w leczeniu pacjentów, u których rozwinął się tętniak tętnicy wieńcowej.22 Według wytycznych American Heart Association, infliximab może być rozważany u pacjentów opornych na IVIG.24

Długoterminowa opieka i zapobieganie ryzyku sercowo-naczyniowemu

Pacjenci po przebytej chorobie Kawasakiego wymagają długoterminowej obserwacji kardiologicznej, szczególnie ci, u których wystąpiły tętniaki tętnic wieńcowych.1416

Monitorowanie kardiologiczne

Seryjne badania echokardiograficzne wykonywane w ośrodku mającym doświadczenie w badaniu tętnic wieńcowych u dzieci są wskazane u pacjentów z ostrą chorobą Kawasakiego.38 Zalecane terminy kontroli echokardiograficznych:3125

  • 1-2 tygodnie po wypisie ze szpitala
  • 6-8 tygodni od początku choroby
  • Dalsze badania w zależności od obecności zmian w tętnicach wieńcowych

Pacjenci, u których wystąpiły tętniaki tętnic wieńcowych, wymagają dożywotniego monitorowania kardiologicznego przez wyspecjalizowane zespoły.14 Nawet jeśli tętniaki ulegną rozwiązaniu, pacjenci ci mają zwiększone ryzyko problemów sercowych w dorosłym życiu.18

Długoterminowa farmakoterapia

Pacjenci z nieprawidłowościami w tętnicach wieńcowych wymagają długoterminowej terapii przeciwpłytkowej.38 W przypadku olbrzymich tętniaków należy dodać warfarynę lub heparynę drobnocząsteczkową.38

Ostre postępowanie u pacjentów z nieprawidłowościami w tętnicach wieńcowych zależy od zasięgu i ciężkości zmian, a decyzje są zwykle podejmowane w konsultacji z kardiologiem dziecięcym.38

Profilaktyka czynników ryzyka sercowo-naczyniowego

Pacjenci po przebytej chorobie Kawasakiego powinni być uważnie monitorowani pod kątem czynników ryzyka sercowo-naczyniowego.39 Zalecenia obejmują:40

  • Ocenę wskaźnika masy ciała
  • Kontrolę ciśnienia tętniczego
  • Ocenę profilu lipidowego (cholesterol całkowity, LDL, HDL, trójglicerydy)
  • Promowanie zdrowego stylu życia (unikanie palenia tytoniu)
  • Regularna aktywność fizyczna
  • Zdrowe odżywianie

41

Zalecenia dotyczące aktywności fizycznej zależą od poziomu ryzyka pacjenta:40

Poziom ryzyka Zalecenia dotyczące aktywności fizycznej
Poziom I i II Brak ograniczeń aktywności fizycznej (nieagonistycznej), jeśli ocena kliniczna i testy instrumentalne są prawidłowe po 6-8 tygodniach
Poziom III Brak ograniczeń aktywności fizycznej (nieagonistycznej) dla dzieci poniżej 10-11 roku życia po 6-8 tygodniach, następnie na podstawie testu wysiłkowego przy każdym nowym wymaganym zaświadczeniu
Poziom IV Aktywność fizyczna ustalana na podstawie corocznego testu wysiłkowego i oceny perfuzji mięśnia sercowego
Poziom V Aktywność fizyczna ustalana na podstawie półrocznego testu wysiłkowego z co najmniej coroczną oceną perfuzji mięśnia sercowego

Badania wskazują, że choroba Kawasakiego powoduje zmiany w metabolizmie lipidów, które utrzymują się po klinicznym ustąpieniu choroby.36 Dlatego ważne jest, aby pacjenci po przebytej chorobie Kawasakiego, nawet jeśli nie rozwinęli tętniaków, korzystali ze zdrowej dla serca diety i stylu życia oraz monitorowania poziomów cholesterolu.41

Szczepienia profilaktyczne

Pacjenci, którzy pozostają na długoterminowej, niskiej dawce aspiryny, powinni otrzymać coroczną szczepionkę przeciwko grypie i być zaszczepieni przeciwko ospie wietrznej.42 Należy również omówić ryzyko rozwoju zespołu Reye’a podczas aktywnej infekcji grypą lub ospą wietrzną.42

Zalecenia dotyczące szczepień obejmują:43

  • Coroczne szczepienie przeciwko grypie, najlepiej we wrześniu lub październiku
  • Inne szczepienia zgodnie z harmonogramem, z wyjątkiem szczepionek zawierających żywe wirusy po podaniu IVIG
  • Odroczenie szczepionek zawierających żywe wirusy (MMR, ospa wietrzna) o 11 miesięcy po podaniu IVIG1544

Podsumowanie działań profilaktycznych

Mimo że nie można zapobiec wystąpieniu choroby Kawasakiego, możliwe jest znaczące zmniejszenie ryzyka powikłań sercowo-naczyniowych poprzez wczesne rozpoznanie i odpowiednie leczenie.19 Odpowiednio wczesne wdrożenie leczenia IVIG i ASA zmniejsza ryzyko rozwoju zmian w tętnicach wieńcowych z 15-25% do około 3-5%.16

Obserwacje z okresu pandemii COVID-19 sugerują, że choroba Kawasakiego może być wywoływana przez czynniki zakaźne, co daje nadzieję na potencjalny rozwój skutecznych strategii profilaktycznych w przyszłości.20 Jak podkreśla dr Rowley: „Kiedy ustalimy dokładną przyczynę, będziemy mogli pracować nad opracowaniem szczepionki, aby zapobiegać tym infekcjom u dzieci”.45

Do tego czasu kluczową rolę odgrywa profilaktyka wtórna obejmująca wczesne rozpoznanie, odpowiednie leczenie i długoterminowe monitorowanie w celu zapobiegania i minimalizowania powikłań sercowo-naczyniowych.4647

    https://www.aafp.org/pubs/afp/issues/2006/1001/p1141.html
    Kawasaki disease is the leading cause of acquired heart disease among children in developed countries. […] First-line treatment for Kawasaki disease is IVIG in a dose of 2 g per kg of body weight in a single infusion. […] For treatment of Kawasaki disease, high-dose aspirin (80 to 100 mg per kg per day, divided into four doses) should be given with IVIG. […] Without treatment, coronary artery abnormalities develop in about 15 to 25 percent of patients with Kawasaki disease. Fortunately, with prompt therapy this percentage decreases to about 5 percent for any abnormality (including transient abnormalities) and 1 percent for giant coronary artery aneurysms. […] Therapy should be initiated within 10 days of fever onset if possible; however, children who present after 10 days of fever still should be treated if fever or other signs of persistent inflammation are present, including an elevated ESR or CRP level.

    At this time there are no means of prevention, nor is there evidence that the disease is contagious. […] If diagnosed with Kawasaki disease, your child will be given a high dose of gamma globulin (purified antibodies) intravenously, which helps prevent damage to the coronary artery. […] Early detection and treatment greatly reduce the risk of future complications.
  • #8 Kawasaki Disease | Tampa Rheumatology
    https://www.tamparheumatology.com/kawasaki-disease.php
    Kawasaki disease is not contagious and cannot be prevented. […] It is important to treat Kawasaki disease as promptly as possible. When treatment is begun within 10 days of onset, the possibility of residual complications is greatly reduced. […] Treatments used to prevent complications include infusions of gamma globulin to lower risk of coronary artery problems and administration of high doses of aspirin to treat inflammation. […] Even after the child has no fever, low-dose aspirin may be administered for at least 6 weeks to prevent blood clotting.

    Rates of Kawasaki disease a condition that creates inflammation in blood vessels in the heart and is more common in children of Asian/Pacific Island descent have substantially decreased in South Korea during the COVID-19 pandemic. […] The decrease could be due to mask-wearing, hand-washing, school closures and physical distancing, suggesting Kawasaki disease may be prompted by infectious agents. […] South Korean researchers noted that efforts to prevent COVID-19 provided a unique opportunity to analyze the possible effects of mask-wearing and social distancing on Kawasaki disease. […] The broad and intensive COVID-19 prevention interventions had the additional effect of lowering the incidence of respiratory infections, which have previously been suggested as triggering agents for Kawasaki disease, Ahn noted.

    The rate of Kawasaki disease in South Korea has substantially decreased during the COVID-19 pandemic, possibly due to pandemic prevention efforts, such as mask-wearing, hand-washing and physical distancing, according to new research published today in the American Heart Association’s flagship journal Circulation. […] Researchers compared the rate of Kawasaki disease from February 2020 to September 2020, a time of significant COVID-19 prevention efforts, to pre-COVID-19 rates of Kawasaki disease. Their analysis found the number of Kawasaki disease cases dropped substantially — by about 40% — after COVID-19 prevention efforts were implemented in Feb. 2020. […] The broad and intensive COVID-19 prevention interventions had the additional effect of lowering the incidence of respiratory infections, which have previously been suggested as triggering agents for Kawasaki disease.

    Kawasaki disease is suspected to be triggered by previous infection. The prevention measures for coronavirus disease 2019 (COVID-19) have reportedly reduced transmission of certain infectious diseases. Under these circumstances, the prevention measures for COVID-19 may reduce the incidence of Kawasaki disease. […] These observations provide a new epidemiological evidence for the notion that Kawasaki disease is triggered by major infectious diseases in children.

    During the COVID pandemic, children were exposed to fewer viruses and other infectious agents. So the 'natural experiment’ that occurred from isolation and masking of children supports the likelihood that Kawasaki disease is triggered by viruses or other infectious agents in the environment. […] The decrease in the incidence of Kawasaki disease after the implementation of non-pharmaceutical interventions is very clear, and it is unlikely that other independent interventions were accidentally involved.
  • #14 Kawasaki disease – Wikipedia
    https://en.wikipedia.org/wiki/Kawasaki_disease
    Typically, initial treatment of Kawasaki disease consists of high doses of aspirin and immunoglobulin. […] Without treatment, coronary artery aneurysms occur in up to 25% and about 1% die. […] With treatment, the risk of death is reduced to 0.17%. […] People who have had coronary artery aneurysms after Kawasaki disease require lifelong cardiological monitoring by specialized teams. […] Children with Kawasaki disease should be hospitalized and cared for by a physician who has experience with this disease. […] To prevent damage to coronary arteries, treatment should be started immediately following the diagnosis. […] Intravenous immunoglobulin (IVIG) is the standard treatment for Kawasaki disease and is administered in high doses with marked improvement usually noted within 24 hours.
  • #15 Kawasaki Disease: Symptoms, Diagnosis and Treatment
    https://www.nationwidechildrens.org/conditions/kawasaki-disease
    When treatment begins within 10 days of the start of the disease, there is little risk of blood vessel and heart problems. […] There is no way to prevent Kawasaki Disease. […] Aspirin helps control fever and inflammation and it keeps blood cells from clumping or forming clots. […] Your child will need to take aspirin for at least 6 weeks after going home. Usually children should not be given aspirin, but in this case, it is needed and helpful. […] Hold off getting vaccines that use live viruses like the MMR and Varicella (chickenpox) for 11 months after having IVIG treatment.
  • #16 Kawasaki Disease: Practice Essentials, Background, Pathophysiology
    https://emedicine.medscape.com/article/965367-overview
    Kawasaki disease (KD), also known as mucocutaneous lymph node syndrome and Kawasaki syndrome, is an acute febrile illness of early childhood characterized by vasculitis of the medium-sized arteries. Given its predilection for the coronary arteries, there is a potential for the development of coronary artery aneurysms (CAAs) and thus sudden death. CAAs develop in approximately 25% of untreated cases; appropriate treatment decreases this risk to 3-5%. […] The principal goal of treatment is to prevent coronary artery disease. Intravenous immunoglobulin (IVIG), a purified preparation of gamma globulin, and aspirin are the mainstays of treatment. Patients should be treated with IVIG within 10 days after the onset of fever to prevent the development of cardiac sequelae. […] Therapy with IVIG should be started within 10 days, and ideally within 7 days, of fever onset to prevent cardiac complications. […] The patient will need to follow up with a primary care doctor and a cardiologist after discharge from the hospital. This is very important so that the patient is appropriately treated and monitored for heart complications.
  • #17 Kawasaki Disease | Symptoms, Diagnosis & Treatment
    https://www.cincinnatichildrens.org/health/k/kawasaki
    Kawasaki disease is an illness that makes the blood vessels in the body swell and become inflamed. […] Without medical evaluation and treatment, however, serious complications may develop and not be initially recognized. […] With appropriate and timely treatment, the risk of coronary artery involvement decreases to around 5%. […] The infusion is most effective if given within the first 10 days of the illness, decreasing the risk of developing coronary changes from 25% to less than 5%. […] Your child will continue to be followed by a cardiologist after Kawasaki disease resolves. […] It is prudent for families and patients to practice heart healthy habits that help to prevent adult coronary artery disease and heart attacks.
  • #18 What Is Kawasaki Disease? Symptoms, Causes, Diagnosis, and Treatment
    https://www.everydayhealth.com/kawasaki-disease/guide/
    With early detection and treatment, long-term heart issues are unlikely to occur. […] The main reason we treat Kawasaki disease is to try to prevent these possible cardiac outcomes, says Vijaya Soma, MD, a clinical assistant professor in the department of pediatrics at New York Universitys Grossman School of Medicine, who specializes in pediatric infectious disease. […] Treatment administered within the first 10 days of symptoms significantly reduces the risk of coronary artery damage and also helps resolve other symptoms. […] Without treatment, up to 25 percent of children develop heart problems such as coronary artery aneurysms, which typically begin one to four weeks after the onset of Kawasaki disease. Treatment lowers the risk of heart complications to about 1 in 20. […] If a child develops aneurysms, they have an increased risk of having heart problems as adults, even if the aneurysms resolve.
  • #19 Prognosis and prevention for Kawasaki disease
    https://www.mymed.com/diseases-conditions/kawasaki-disease/prognosis-and-prevention-for-kawasaki-disease
    Generally, Kawasaki disease will resolve through early treatment within four to eight weeks, after which, you can expect a full recovery. […] As with most illnesses, when your child is diagnosed early, the risk of complications arising is significantly decreased. It is vital that you recognise the signs and symptoms of Kawasaki disease and make an appointment to see your doctor if you feel your child may be ill. […] Due to the fact that the exact cause of the condition is yet to be identified, there are currently no measures in place that have been known to prevent the occurrence of the disease. This makes the early detection of the disease vital in preventing further complications.
  • #20 Breakthrough Toward Finding Cause of Kawasaki Disease in Children | Lurie Children’s
    https://www.luriechildrens.org/en/news-stories/breakthrough-toward-finding-cause-of-kawasaki-disease-in-children/
    Establishing the exact cause, which is believed to be viral, is critical to advancing the diagnosis, treatment and prevention of Kawasaki disease. […] The standard treatment, intravenous immunoglobulin and aspirin, substantially decreases the risk of heart disease in Kawasaki disease patients. […] Once we establish the cause of Kawasaki disease, we can work on developing a vaccine to prevent these infections in children, says Dr. Rowley. […] We have the responsibility to keep searching, to deliver those answers and optimize diagnosis, treatment and prevention of Kawasaki disease.
  • #21 Kawasaki Disease: Mysterious Childhood Illness | Maggie Yu MD, IFMCP
    https://drmaggieyu.com/blog/kawasaki-disease-mysterious-childhood-illness/
    Kawasaki disease, this mysterious childhood illness, has no specific prevention measures due to its unknown cause. However, theres a standard treatment protocol that includes immunoglobulin therapy and aspirin management. […] The tricky thing about Kawasaki disease is that we dont know what causes it. Its like trying to dodge raindrops in a storm without knowing where theyll land next. This makes it challenging to develop specific preventive measures. […] When your kiddo gets diagnosed with Kawasaki disease, the go-to treatment is something called intravenous immunoglobulin (IVIG) therapy. Think of IVIG as a superhero swooping in to save the day! Its a blood product administered through veins that helps reduce inflammation and protect against heart damage. […] Apart from IVIG therapy, doctors often use an old-school remedy aspirin. Yeah, Im talking about that over-the-counter pill you take for headaches or fevers! In this case, aspirin helps manage inflammation and reduces fever associated with Kawasaki disease.
  • #22 Kawasaki Disease Program | Children’s National Hospital
    https://www.childrensnational.org/get-care/departments/kawasaki-disease-program
    Kawasaki disease is a condition that causes inflammation in a childs body and blood vessels in multiple organs, including the coronary artery in the heart. […] If your child is experiencing high fever, swollen limbs, peeling skin, red eyes and swollen reddish tongue, we recommend that your child receives treatment as soon as possible to avoid the development of coronary artery aneurysms. […] Aspirin helps treat your childs inflammation and prevents clots from forming in the coronary artery. Aspirin can also decrease pain, joint inflammation and fever. […] Intravenous immune globulin (IVIG). We will infuse the immune protein (gamma globulin) through your childs vein which can lower the risk of developing coronary artery problems. This helps to reduce inflammation in your child. […] Once your child is discharged from the hospital, we strongly suggest that your child visit a cardiologist one to two weeks after discharge and then six weeks after discharge. […] If your child has developed a coronary artery aneurysm, we will treat your child with: Infliximab. This monoclonal antibody works to enhance your child’s immune system. […] It’s important to keep follow-up visits with your child’s healthcare provider, even if your child is feeling well.

    It’s best to start treatment for Kawasaki disease as early as possible, when your child still has a fever. Treatment for Kawasaki disease often happens in a hospital. The goals of treatment are to lower fever, reduce swelling and prevent heart damage. […] Gamma globulin is given through a vein. This treatment lowers inflammation in the blood vessels. It can lower the risk of problems with the heart artery. […] After getting gamma globulin, wait at least 11 months to get a live vaccine, such as the chickenpox or measles vaccine. Gamma globulin can affect how well these vaccines work. […] High doses of aspirin might help treat inflammation. Aspirin also can decrease pain, joint swelling and fever. […] A healthcare professional needs to oversee giving aspirin to children with Kawasaki disease.

    https://emedicine.medscape.com/article/965367-treatment
    The principal goal of treatment for KD is to prevent coronary artery aneurysms and other cardiac complications. The mainstays of treatment for KD are IVIG and aspirin. All patients with KD should be admitted to the hospital for administration of IVIG, echocardiography, initiation of aspirin, and for observation until fevers have resolved. […] It is important to note that the American Academy of Pediatrics Red Book states that live vaccinations are contraindicated for 11 months after administration of IVIG for KD. […] Guidelines from the AHA recommend a second dose of IVIG, methylprednisolone, a longer tapering course of prednisolone or prednisone plus IVIG, or infliximab be considered for patients resistant to IVIG. […] Guidelines from the ACR and the Vasculitis Foundation conditionally recommend the use of adjunctive glucocorticoids with IVIG as initial therapy for patients with acute KD who are at high risk for IVIG resistance or the development of coronary artery aneurysms.

    Even though the risk is low, it is important that the child be followed closely in the first six weeks after the diagnosis [of Kawasaki disease] is made to see if the coronary arteries show signs of being affected. […] The AAP recommends that live viral vaccines be postponed for 11 months after a child is treated for Kawasaki disease, because the treatment may reduce the effectiveness of vaccines for illnesses including MMR (measles, mumps, rubella) and varicella (chicken pox).

    Aspirin has been used in the treatment of KD for its anti-inflammatory activity at high doses (early in the disease) and anti-platelet activity at low doses (for chronic thromboprophylaxis). […] There is no evidence that aspirin decreases the incidence of coronary artery abnormalities, and there is no data to suggest that a high vs. moderate dose of aspirin is superior. […] The AHA guidelines state it is reasonable to administer moderate- or high-dose aspirin until the patient is afebrile, although there is no evidence it reduces coronary artery aneurysms. […] This pathway does not recommend high-dose aspirin in those already receiving steroids, since steroids offer a powerful anti-inflammatory effect. […] This pathway suggests transitioning to low-dose ASA after 24 hours to allow for a better assessment of fever and treatment resistance prior to discharge.

    High-dose aspirin is administered initially for its anti-inflammatory effect. […] Low-dose aspirin (3 to 5 mg per kg per day, given as a single dose) has an antiplatelet effect and should be continued until six to eight weeks after disease onset if there are no coronary artery abnormalities or indefinitely if abnormalities are present. […] In general, ibuprofen should be avoided in children taking aspirin because it may antagonize the antiplatelet effect of aspirin. […] About 85 to 90 percent of patients respond promptly to initial therapy of IVIG and high-dose aspirin; however, others have persistent or recurrent fever beyond 36 hours of therapy and require further treatment. […] In most centers, patients who fail to respond to the first dose of IVIG are given a second dose of 2 g per kg.

    Adjunctive corticosteroid therapy has been shown to reduce the rate of coronary artery dilation in children at high risk for IVIG resistance in multiple Japanese clinical studies (most notably RAISE study group). […] A significant proportion of children diagnosed with MIS-C, a post-infectious syndrome of SARS-CoV-2 infection, meet criteria for Kawasaki disease. Further investigation is warranted to further delineate these conditions and optimize treatment of these conditions given the ongoing COVID-19 pandemic. […] The 2017 American Heart Association (AHA) treatment guidelines have included changes in aspirin dosing (including both 80100 mg/kg/day and 3050 mg/kg/day treatment options), consideration of the use of adjuvant corticosteroid therapy in patients at high risk of IVIG resistance, and the change in steroid regimen for refractory KD to include both pulse-dose IVMP and longer course of prednisolone with an oral taper.

    Aspirin is used with intravenous immunoglobulin (IVIG) to prevent coronary artery abnormalities in KD. […] The initial treatment of KD with IVIG has generally reached consensus worldwide. However, there is still controversy about the appropriate aspirin dose to be used as a secondary cornerstone treatment. […] In conclusion, our data show that in clinical practice, the commonly recommended dosage of 3050mg/kg/day of aspirin is not better than 2029mg/kg/day.

    Once the fever goes down, a child might need to take low-dose aspirin for at least six weeks. This can be longer if there are problems with the heart artery. Aspirin helps prevent blood clotting. […] If your child has any signs of heart problems, the healthcare professional might suggest follow-up tests to check your child’s heart health. Tests are often done 6 to 8 weeks after the illness began, and then again after six months.

    For patients with increased risk of thrombosis (large or giant aneurysms and recent history of coronary artery thrombosis), triple therapy with antiplatelet medications, 2nd antiplatelet agent and anticoagulation may be considered. […] Ibuprofen and other NSAIDs may be harmful in patients taking ASA for its antiplatelet effects and should be avoided. […] Avoid ibuprofen or other NSAID (antagonizes anti-platelet effect of aspirin and clopidogrel). […] There is no evidence that ASA decreases aneurysms or that outcomes are different with low- vs. high-dose ASA. […] Low-dose ASA is necessary for thrombosis prevention and should be continued through discharge, with length of therapy.

    IVIG given within the first 10 days of the disease reduces the risk of damage to the coronary arteries in children, without serious adverse effects. […] Aspirin therapy is started at high doses until the fever subsides, and then is continued at a low dose when the patient returns home, usually for two months to prevent blood clots from forming. […] Due to the potential involvement of the upregulated calcium-nuclear factor of activated T cells pathway in the development of the disease, a 2019 study found that the combination of ciclosporin and IVIG infusion can suppress coronary artery abnormalities. […] Evidence indicates Kawasaki disease produces altered lipid metabolism that persists beyond the clinical resolution of the disease.

    Although combined therapy led to lower incidence of coronary artery abnormalities, important caveats may limit the findings’ relevance. […] Cyclosporine targets genetic variants related to Kawasaki disease and its consequences, making it a candidate for therapy, particularly in children at higher risk for not responding to intravenous immunoglobulin (IVIG) alone. […] Overall incidence of coronary artery abnormality was lower in the intervention group (14% vs. 31%; risk ratio, 0.46; 95% confidence interval, 0.25–0.86), but prevalence at 12 weeks was not statistically different. […] Given the still uncertain balance between risks and benefits, clinicians considering this approach should be aware of the important caveats.

    Serial echocardiography, performed at a center experienced in examining the coronary arteries of children, is indicated for those with acute Kawasaki disease. […] The acute management of patients with coronary artery abnormalities depends on the extent and severity of the lesion, and decisions usually are made in consultation with a pediatric cardiologist. […] Long-term antiplatelet therapy is indicated for these patients, and warfarin or low-molecular-weight heparin should be added for patients with giant aneurysms.

    But if your child doesnt develop a coronary aneurysm, they are likely to have an excellent long-term outcome, according to the AAP, which says that after treatment, children will benefit from a heart-healthy diet and lifestyle, and monitoring of cholesterol levels. […] The standard treatment for Kawasaki disease consists of high doses of both aspirin and immunoglobulin, which is a purified form of proteins and antibodies from donated blood. […] These treatments can substantially reduce the risk of serious heart complications and should be started as soon as possible. […] Children with large coronary aneurysms may be given anticoagulants, which are drugs that prevent the blood from clotting. […] The risk of developing coronary disease in children treated with immunoglobulin therapy is low, says Daphne T. Hsu, MD, the division chief of pediatric cardiology and the co-director of the pediatric heart center at Childrens Hospital at Montefiore in New York City.

    Patients who remain on long-term, low-dose aspirin should receive an annual influenza vaccine and be vaccinated against varicella. Additionally, the risks of developing Reye syndrome during an active infection with influenza or varicella should be addressed. […] Long-term management begins at the end of the acute illness, typically 5-6 weeks after fever onset. This is typically when coronary artery involvement has reached its maximal extent and luminal dimensions. Thromboprophylaxis and careful echocardiographic surveillance for coronary artery stenoses and obstructions, as well as myocardial ischemia, are the pillars of management.
