My son was diagnosed with ITP at 10. We were hoping it would be an acute case, but unfortunately we have passed the year mark and he's now considered chronic. Luckily, his platelets have been stable for the past six months, staying in the 80s. Our hematologist ran anti-TPO thyroid checks and his levels are off the charts in the three times he has been checked. Does anyone have experience with Hashimoto's or other thyroid disease/conditions in children? If so, did treatment with thyroid medication improve platelet counts? We are planning to see an endocrinologist soon. In the meantime, I'm incredibly worried that this autoimmune issue along with the ITP could be indicative of a worse condition.
