On behalf of HSANZ President Leanne Berkahn and Vice President Steven Lane, this note is being shared from THANZ.
Amidst the community concerns regarding COVID and COVID vaccination, some of us have noted cases of thrombocytopenia following COVID vaccination. Although immune thrombocytopenia (ITP) has been described in the medical literature following mRNA vaccines (Pfizer), we are now accumulating local experience with this phenomenon after AstraZeneca vaccination.
We are now LIVE with an online HREC approved REDCap registry to collect de-identified data on the presentation and clinical outcome of cases that you believe may represent an immune thrombocytopenia (Vaccine Induced ITP) following any COVID vaccination (Pfizer, AstraZeneca, etc). Some of these cases may occur as a relapse in patients with a prior history of ITP. Many cases may be de novo. Some patients may even share features with VITT/TTS (Vaccine Induced Immune Thrombosis and Thrombocytopenia). We would like to collect information on any of these presentations.
Please do not hesitate to contact us directly
