When will they show up? What should you do if you suspect that you have such an adverse event? From clinical symptoms to treatment, what you need to know about VITT (immune thrombocytopenia caused by vaccines).
Thrombus and low platelet levels after vaccination with the viral vector Covid vaccine: The 18-year-old Ligurian casePeople who died after being vaccinated with AstraZeneca raised concerns about the risks represented by such adverse events. Although such adverse events are very rare, they mainly affect the youngest, especially women.In Italy, nearly 9 million doses of AstraZeneca injection have 45 reports of rare thrombosis. According to European data, these reports average 1 case per 100,000 dosesFor other viral vector vaccines (Jonhson & Jonhson), the incidence rate cannot be estimated due to the small doses used so far.
What are the symptoms of thrombosis after vaccination?
The European Medicines Agency (EMA) has recognized that there may be a link between the use of viral vector vaccines and vaccination. Vaccine-induced immune thrombotic thrombocytopenia (VITT, vaccine-induced immune thrombocytopenia). This condition is characterized by thrombotic events related to reduced platelet counts, which are clinically very similar to heparin-induced thrombocytopenia, in which excessive aggregation of platelets leads to vascular obstruction and the resulting blood clots, which may be life-threatening. Given the severity, it is important to understand the symptoms. If quickly identified, the risk of poor prognosis and poor prognosis can be minimized. Symptoms may include:
- Swelling of arms or legs
- Persistent abdominal pain
- Severe or persistent headache (headache)
- Blurred vision, confusion or convulsions, dizziness
- Shortness of breath or difficulty breathing
- Chest pain
- Bleeding outside the injection site, unusual skin bruises or petechiae
When do symptoms appear?
Symptoms of rare thrombosis may occur five days to three weeks after vaccination.
what to do?
If you experience one of the symptoms attributed to VITT, you need counseling See a doctor immediatelyAs mentioned earlier, this condition is rare, but it is very serious and requires prompt treatment.
Is there any effective treatment?
After the first case report of VITT, the treatment plan issued by the Academy of Sciences prescribes intravenous injection Immunoglobulins and anticoagulantsIn particular, the EMA-indicating the instructions from Aifa-emphasizes the guidelines provided by the International Association of Thrombosis and Hemostasis (Isth) and reminds thrombotic syndromes related to thrombocytopenia that rapid identification and urgent clinical management are needed.”
