So in a nutshell, this is the unknown
cause of the destruction of platelets
and is diagnosed when the patient's platelet
count gets less than 100,000 per microliter.
Acute ITP is more common
in young children ages 2 to 6
and is usually present 3 weeks after a viral illness
and self resolves in a few weeks to a few months.
Chronic ITP is more common in females
and adults and is managed by a hematologist.
Post-viral antibodies will accidentally
mark the platelets for destruction
and these platelets will be destroyed
at a pace that exceeds their production.
The patients will develop petechiae
and purpura and this can be sudden.
Remember the findings of the CBC are totally normal except
for the decreased platelet count -thrombocytopenia .
The clotting studies are normal.
The bone marrow aspiration
excludes other causes like malignancies.
Bleeding in the setting of ITP
can be severe and life-threatening.
There are treatment options even
though this can self-resolve without them
but you can treat the patient with steroids and you need
to provide a safe environment with bleeding precautions.
Thank you for watching this lecture on ITP.
