O\u010dkov\u00e1n\u00ed proti COVID-19 a akutn\u00ed po\u0161kozen\u00ed jater: Souvislost s spike proteinem?<\/strong><\/span><\/p>\n

Ned\u00e1vn\u00e1 studie zkoumala vz\u00e1cn\u00e9 p\u0159\u00edpady autoimunitn\u00ed hepatitidy po o\u010dkov\u00e1n\u00ed proti SARS-CoV-2 a zavedla term\u00edn\u00a0po\u0161kozen\u00ed jater spojen\u00e9 s vakc\u00ednou SARS-CoV-2<\/em>\u00a0(SVALI). V\u00fdzkumn\u00edci analyzovali glob\u00e1ln\u00ed data a mo\u017en\u00e9 mechanismy, p\u0159i\u010dem\u017e zvl\u00e1\u0161tn\u00ed pozornost v\u011bnovali roli spike proteinu z vakc\u00edny, kter\u00fd by mohl vyvolat abnorm\u00e1ln\u00ed imunitn\u00ed odpov\u011b\u010f. Akutn\u00ed po\u0161kozen\u00ed jater po vakcinaci je vz\u00e1cn\u00e9, ale pohybuje se od samoomezuj\u00edc\u00edho a\u017e po z\u00e1va\u017en\u011bj\u0161\u00ed p\u0159\u00edpady vy\u017eaduj\u00edc\u00ed dlouhodobou imunosupresi nebo v extr\u00e9mn\u00edch p\u0159\u00edpadech transplantaci jater.<\/p>\n
