“5月現在 5, 2022, CDC and state partners are 調査中 109 children with hepatitis of unknown origin across 25 states and territories, more than half of whom have tested positive for adenovirus with more than 90% 入院, 14% with liver transplants, and five deaths under investigation,” the CDC said.
約 18% of cases worldwide actively also tested positive for COVID-19, according to a Medical Xpress report.
“The big focus over the next week is looking at serological testing for previous exposure and infections with COVID,” Philippa Easterbrook, from the WHO’s global hepatitis program, told a press 会議.
Easterbrook said within the week the United Kingdom will have data on a case control study comparing whether the detection rate of adenovirus in the children who have hepatitis differs from that in other hospitalized children who don’t have the liver disease.
“That will really help hone down whether [adenovirus] is just an incidental infection that’s been detected or there is a causal or likely causal link,” Easterbrook 前記.
“A fundamental question is whether there is a characteristic pattern in the pathology of the liver in these patients. Such a pattern might be seen at the advanced stage when liver transplantation was performed, or earlier before the severe liver damage of the unknown process had perhaps obscured an earlier characteristic pattern,” 博士は言った. Daniel Lucey, clinical professor of medicine at Dartmouth Geisel School of Medicine.
“If such a liver pathology pattern has been found, then it could be used to help identify the etiology of the hepatitis or at least serve to provide a unifying clinical-pathologic syndrome as soon as possible.”
None of the U.K. liver samples ” … show any of the typical features you might expect with a liver inflammation due to adenovirus but we are awaiting further examination of biopsies,” Easterbrook 追加されました.
Because adenoviruses are used in some of the COVID-19 vaccinations, one theory on social media suggested a link between the jab and the hepatitis outbreak in the U.K., where most of the cases have been reported, による ロイター.
But these adenoviruses in the vaccines are “harmless transporters which have been modified so they cannot replicate or cause infection,” according to BBC ニュース.
“There is no evidence of any link to the coronavirus (COVID-19（新型コロナウイルス感染症) ワクチン. The majority of cases are under 5 年, and are too young to have received the vaccine,” the U.K. Health Security Agency (UKHSA) 前記.
The United Kingdom International Health Regulations National Focal Point first reported 10 cases of severe hepatitis of unknown etiology on April 5, 2022, in children ranging from 11 months to 5 years old in Scotland, the WHO 前記.
“The highest numbers of cases so far are: イギリス. (163), 米国 (109), イタリア (35), スペイン (22), ブラジル (16), インドネシア (15), イスラエル (12), スウェーデン (ナイン), アルゼンチン (8), 日本 (セブン) CNNアナリストは「タイヤを大幅に削減する」と呼びかけています (セブン).”
More than five cases have only been reported in six countries. The United Kingdom have reported the most cases in the world, but no child has died so far in the country, according to a May 12 UKHSA ステートメント.
Hepatitis, otherwise known as liver inflammation, is commonly caused by viruses, medications or exposure to certain chemicals, による Healthline.
“Most of the children in the reported cases presented with gastrointestinal symptoms such as vomiting, diarrhea, そして abdominal pain,” ビリー・ロードは、オースティン・ライデルとの結婚式で亡くなった母親と祖母を称えます. Norberto Rodriguez-Baez, a professor of pediatrics at the University of Texas Southwestern Medical センター.
“These symptoms were followed by development of jaundice,” 彼 追加されました.
Jaundice is when the skin and eyes turn yellow because the liver loses its ability to clear bilirubin properly, per Healthline.
“興味深いことに, fever was not described as a common symptom in these cases. 加えて, all children were previously 元気,” Rodriguez-Baez said.
“It’s important that parents know the likelihood of their child developing hepatitis is extremely low. We continue to remind everyone to be alert to the signs of hepatitis – particularly jaundice, look for a yellow tinge in the whites of the eyes – and contact your doctor if you are concerned,” 博士は言った.
