Acute hepatitis in kids. We urge colleagues with access to samples (blood/liver tissue) to consider SARS-CoV-2 superantigen-mediated disease, potentiated by a second virus (AdV) 🧵1/…
2/ @ArditiMd and colleagues first described a superantigen motif in SARS-CoV-2 and several groups have independently found T-cell skewing (TRBV11-2 expanded) in kids w #MISC, indicative of a superantigen-mediated inflammation.
3/ Multiple reports have reported intestinal SARS-CoV-2 persistence and leakage of superantigens into the bloodstream trigger immune activation and possibly MIS-C in susceptible individuals, @laelyonker et al

La incidencia del #MISC fue de 1 por cada 3.400 personas no vacunadas con la variante delta.

La eficacia estimada de la vacuna contra el MIS-C inducido por delta fue del 94% en personas de 5-17 años.

Nuevo estudio poblacional de Dinamarca.
"Sugerimos que la efectividad de la vacuna contra MIS-C se debió a una alta protección de la vacuna contra la infección con la variante delta y posiblemente a un efecto directo de la vacuna sobre el riesgo de desarrollar MIS-C después de una infección postvacunación".
"El estudio agrega conocimiento importante sobre la incidencia del MIS-C en función de la variante de la infección anterior por SARS-CoV-2 y hasta qué punto el MIS-C es una enfermedad prevenible por vacunación".

Let's talk about the mystery epidemic of #hepatitis in children. It's most likely a complication of #COVID19 but may take a while to be adjudicated as such. The syndrome has been seen in children <17, mostly unvaccinated kids <5 years. A thread.
Hepatitis is a known presentation of #MISC… & MISC is a late complication, after the acute infection. So, the fact that PCR is negative is not surprising.
Also, kids do not have as robust an antibody response as adults so may be -ve on serology too.…

Jetzt stellen wir uns mal vor, @jokoundklaas gewinnen gegen @Pro7 und nutzen ihre Sendezeit für das Thema #LongCovid , #longcovidkids , #pims / #misc , #MECFS ...😱🤗❤
Oder anstatt #Neidoo Sendezeit zu geben, schenken @ardmoma , @ARDde , @ZDFheute , @ZDF , @tagesschau , @WDR , @ndr usw dem Thema #LongCovid, #longcovidkids, #pims, #MECFS, #misc, #postcovid Sendezeit.

Haben die nicht auch sowas wie einen Bildungsauftrag? Frage für eine Freundin
Welche Sender sollten eurer Meinung nach den Themen #LongCovid , #PostCovid , #LongCovidkids , #pims , #misc , #MECFS , etc mehr Aufmerksamkeit und somit Sendezeit schenken? Welche Fachleute würdet ihr gerne dazu hören? Postet mal bitte hier drunter ⬇️

1000 Dank ❤

The importance for quick data sharing & finding the cause for unclear #hepatitis in #children is also for the right treatment. Huge difference if it needs antiviral treatment (that only makes sense when there is actually virus) or treatment for an immune-mediated pathogenesis.
Since this is ongoing since a while, I would love to see some early data, even if preliminary (biopsy findings). And yes, transparent communication on #SARSCoV2 #COVID19 serology would also help against speculation of any kind. There are aspects for & against each theory.
Since parents were re-assured by governments & MANY health professionals that catching #SARSCoV2 #COVID19 is not a big deal for children (& therefore few - no efforts to mitigate transmission), any link, however low the plausibility, deserves a thorough & transparent assessment

Bilan #PIMS #Covid #Enfant du 31/03/22

Pourquoi @SantePubliqueFr ne veut pas conclure sur l’évidence d’une bonne nouvelle ?!

Omicron ne fait quasi pas de Pims mais ils ne veulent pas le dire..

"le pic des PIMS est survenu une semaine avant le pic des hospits et la décroissance semble.. suivre celle des hospits.

=> Ce constat permet de supposer un IMPACT DIFFERENT DU VARIANT OMICRON.. sur l’épidémiologie des PIMS"

Le 17/02/22, SPF constate que la vague de Pims vient "essentiellement" de la vague Delta. Cette affirmation concerne la semaine 6.
Après la semaine 7, ça baisse fortement.

Il n’y a donc pas de vague de PIMS concernant OMICRON.

"James was six when he had PIMS. He was misdiagnosed twice at a local hospital and eventually treated in intensive care at St Mary's, Paddington.
The rare post Covid condition is sometimes missed multiple times by medics"
"parents fear the situation will get worse with the end of free coronavirus testing."

PIMS – Paediatric Inflammatory Multisystem Syndrome
"PIMS is caused by the immune system which fights off the virus but then over-reacts to affect other parts of the body."
"prompt diagnosis and treatment are essential for best outcomes with PIMS, as delays can lead to life changing heart and organ damage and sometimes death. Diagnosis is challenging, however"

Wichtige Info: wer bei seinem Kind 4-6 Wochen nach #COVID19 #SARSCoV2 (und auch ohne bekannte Infektion) Fieber & Verschlechterung des Allgemeinzustands bemerkt, sollte sofort einen Arzt konsultieren. Anstieg an #PIMS #MISC bei aktuell sehr hohen Zahlen bald zu erwarten #Schweiz
Ich würde mir wünschen, dass wenigstens ein einziger Politiker sagt: “Wir sind uns bei unseren Entscheidungen bewusst, dass in den nächsten Wochen vermehrt #Kinder an #PIMS erkranken & die Hälfte davon auf Intensivstation muss, trotzdem lockern wir & ändern nichts an den Schulen”
Auch wenn die Erkrankung eine gute Prognose hat, so trifft es idR zuvor vollkommen gesunde Kinder, die ohne #COVID19 #SARSCoV2 auf eine Intensivstation kommen würden. Niemand möchte das für sein Kind. Impfung bietet einen guten Schutz davor.

#omtadvies over 🏥 en IC-opnames: in modellen nu wel passendere aannames over #omikron en #booster:
- 40-60% minder kans 🏥
- ligduur 5 ipv 7-8 dagen
- kans IC na 🏥opname 10% ipv 16-21%
- korter serieel interval 3,5 ipv 4 dagen
- booster 90% >60 jaar, 73% >18 jaar

Avondlockdown leidt dan tot een piekbezetting rondom tot net boven de deltapiek begin december 2021:
- 550-600 opnames per dag met een bedbezetting van 4000-4500
- 60-70 IC opnames per dag met een IC-bezetting van 700-800

- grote mate van onzekerheid: kan ook boven de bezetting van de deltapiek uitkomen
- effect versoepelen quarantaine kinderen niet meegenomen
- gaat uit van sluiting 17 uur (niet 22 uur en overdracht bepaald door aantal contacten maar ook door duur en intensiteit)

“The most feared consequence of having MIS-C is actually that the heart does not function appropriately and the blood pressure can drop to life-threatening levels, Helen Devos Children’s Hospital pediatric infectious diseases specialist Dr. Rosemary Olivero said"
His body first broke out in a rash, which was followed by a fever.

Hoe dik kun je het er bovenop leggen?
- #ScholenOpen mislukt door toename besmettingen en quarantaine.
- We publiceren nu dat quarantaine slecht is voor kinderen.
- #MISC ⁉️ #LongCovidKids⁉️…… Image
Voor de duidelijkheid.
Quarantaine bij negatieve test is 5 dagen online onderwijs - dat is max een schoolweek.
Corona duurt veel langer!

Praten over #onderwijsachterstand negeert opzettelijk de strategie van #groepsimmuniteit.
@WHO had geklaagd over nieuwe inzet hiervan. Image
Groepsimmuniteit door infectie is, ook na vaccinatie, nog steeds onwetenschappelijk en onethisch.

Kans dat langdurige immuniteit na vaccinatie en infectie en wel ontstaat terwijl dit niet gebeurde na infectie en vaccinatie, infectie of vaccinatie is vrijwel nihil.

How come #COVID19 is mostly mild in children? And why do #MISC affect mostly young people?

An interesting hypothesis by @BrodinPetter considering the trade-off between growth and immunity, while most of the studies focus on resistance rather than tolerance 1/
Tolerance to the initial infection may allow virus to stay in gut longer, leak through gut wall, and trigger T cell activation. Could a milder systemic immune response lead to viral persistence in the gut of children? 2/
“Energy allocation for growth increases the threshold to mount expensive systemic inflammatory responses unless absolutely required”

How come #COVID19 is mostly mild in children? and at the same time, why do the rare hyperinflammatory syndrome #MISC affect mostly young people, and not the elderly? thread🧵and a hypothesis:… Image
2/In other infections, ex mononucleosis, symptomatic disease in teenagers differs from mild/asymptomatic infection in young children by stronger bystander T-cell activation and systemic inflammation.
3/But what limits systemic inflammatory responses in young children? One likely explanation is that energy allocation for growth increases the threshold to mount expensive systemic inflammatory responses unless absolutely required...

#Omicron macht Hoffnung auf eine Ende der #Pandemie & endemische Situation. #SARSCoV2 #COVID19 auf Basis einer Impf-Immunität ist weniger krankmachend & wird früher oder später (wohl eher früher bei aktuellen Inzidenzen) jeden treffen. Vergisst man hier nicht jemanden? #Kinder
Kinder unter 5 haben noch keinen Zugang zur Impfung, können die nicht-pharmazeutischen Maßnahmen nur bedingt bis garnicht umsetzen (Maske, Abstand), haben viele Kontakte bei Fremdbetreuung & werden sich genauso anstecken wie alle anderen auch, aber ohne vorherige Impf-Immunität
Spiegelt sich in vielen Ländern bereits bei Hospitalisierungszahlen wider, vor allem Kinder < 1 Jahr. Es macht mich traurig, wie wenig man dazu in der öffentlichen Diskussion um Omicron überhaupt noch hört. Auch Omicron macht die Durchseuchung der Kinder nicht verantwortenbar

“He used to have so much energy and right now he does not... it’s very different to see him very tired & not being able to do some of the things he used to. We have faith he will be one day, but it’s going to be a long road to recovery.”
Cameron Dye was released from the ICU on Dec. 29 after being intubated for several days and receiving intravenous immune globulin therapy and high dose steroids, Hailey Dye said.

First they said...

🌹First they said it doesn’t affect kids, it’s just the elderly. I didn't speak out because I was not old.

🌹 Then, they said don’t panic it’s just the sick & only those with comorbidities. I didn't speak out because I was not vulnerable.

🌹 Next, they said it’s ok if kids spend some days in hospital. I didn't speak out because my kids were not in hospital.

🌹Then, they said it's very few who get #LongCovid & #MISC post Covid. I didn't speak out because my kids didn't have side effects. 2/4
🌹Then,they said #childhospitalisations are high. But don't panic. They are hospitalised #withCovid and not #forCovid. I didn't speak out because my kids were asymptomatic. 3/4

🧵One of the great UNKNOWNS about the Omicron variant is the impact on children 4 weeks AFTER infection.
Before #Omicron 6,431 children in the U.S. were hospitalized for multi-system inflammatory syndrome (MISC) due to COVID & 55 of those kids died. Kids with MISC are SICK & require ICU care, often with blood pressure support, steroids, blood thinners, and sometimes life support
MISC is an inflammatory reaction in the body that develops about 4 weeks after infection with COVID. Each rise in COVID infection has been followed by an increase in #MISC 4 weeks later.…

Children infected with COVID-19 are at higher risk of developing diabetes.
This article published in June 2021 discussed two NIH-supported studies confirming SARS-CoV-2 can target and impair the body’s insulin-producing cells.
Type 1 diabetes occurs when beta cells in the pancreas don’t secrete enough insulin to allow the body to metabolize food optimally after a meal. As a result of this insulin insufficiency, blood glucose levels go up, the hallmark of diabetes.
