Thrombocytes (blood platelets) are tiny particles in the blood
that are essential for blood clotting, and thrombocytopaenia is
a deficiency of these platelets.
Symptoms include petechiae (Small haemorrhages,
or pinpoint lesions, on the skin), excessive bruising, &
Idiopathic thrombocytopaenic purpura (ITP) is a condition where
there are decreased platelet counts, along with the presence of
platelet antibodies. ITP can be present in patients who do not have
lupus. It is usually treated with corticosteroids, or with low doses
of a drug called danazol.
Lupus patients can also get qualitative platelet defects. Functional

range. NSAIDs and steroids disrupt platelets, and induce purpura
(black and blue marks on the skin). I
