What's Behind Immune Thrombocytopenia (ITP)?
Published: Nov 24, 2023
ITP can arise from various triggers, and understanding these can help in managing the condition.
Autoimmune Triggers
The primary cause of ITP is an autoimmune reaction where the immune system mistakenly attacks platelets. This can occur without any other apparent illness, known as primary ITP. In other cases, it may be linked to autoimmune diseases like lupus, where immune dysregulation is already present.
Infections and Vaccines
Certain infections such as HIV, hepatitis C, and even COVID-19 have been associated with ITP. These infections may trigger the immune system to mistakenly target platelets. Additionally, some people have developed ITP following vaccinations, though this is rare and not proven to be a direct cause.
Medications and Other Factors
Some medications can induce thrombocytopenia, which can mimic or exacerbate ITP. Drugs like certain antibiotics and quinine are known culprits. It's essential to review all medications with your healthcare provider if experiencing symptoms of low platelets.
