Vienna: A group of medical doctors at Medical College of Vienna handled a 62-year-old girl affected by a uncommon thrombosis noticed in individuals following AstraZeneca vaccination in opposition to Covid-19.
The situation medically known as VITT (vaccine-induced thrombotic thrombocytopenia) is related to a low thrombocyte (blood platelet) rely and a clotting dysfunction. It happens at uncommon websites within the physique.
Following vaccination, the affected person developed vaccine-induced prothrombotic immune thrombocytopenia (VIPIT).
The affected person was admitted on the Division of Drugs on the College with a low platelet rely and low fibrinogen ranges. Fibrinogen is a protein that performs a serious function in blood clotting. Her situation confirmed all indicators of the start of thrombosis.
The medical doctors rapidly handled the affected person with a excessive dose of intravenous immunoglobulin concentrates, cortisone and particular anticoagulants, in order that thrombosis was prevented. Immunoglobulin concentrates include antibodies that may block the misdirected immune response. The standard heparin preparations should not be used to forestall clotting, since they’ll set off thrombosis, or worsen it. The affected person responded instantly to the remedy.
“On this case we had been in a position to describe, for the primary time, the efficacy of a doubtlessly life-saving remedy technique for vaccine-induced thrombosis,” mentioned coagulation specialist Paul Knobl, on the varsity.
The findings have been printed within the Journal of Thrombosis and Haemostasis. Whereas the findings assist the present remedy suggestions, additionally they present that immediate analysis and quick initiation of remedy are mandatory to be able to stop a life-threatening thrombosis.
VITT is most likely brought on by a faulty immune response, whereby thrombocyte-activating antibodies are produced leading to thrombocytopenia (low platelet rely) and thrombosis. The mortality charge in VITT is excessive (40-50 per cent) and the syndrome requires quick and acceptable remedy.
Uncommon blood clotting following AstraZeneca vaccination have been reported from varied nations together with India, UK and the US. Nonetheless, research have proven the dangers far outweigh the advantages supplied by the vaccinations.
