ABSTRACT
Refractory thrombotic thrombocytopenic purpura is characterized
by a persistent or passing decrease in platelet count,
which increases the risk of bleeding depending on the degree
of thrombocytopenia. This condition results from an
imbalance between megakaryocyte platelet production and
their accelerated destruction. Additionally, platelet production
is affected by two main mechanisms: 1) intramedullary
destruction of antibody-coated platelets by macrophages
and 2) inhibition of megakaryopoiesis. The chronic form
of the disease can be described as lasting longer than six
months, and while spontaneous remissions may occur, they
are infrequent. This manuscript reviews the risk factors, clinical
manifestations, and available treatment options for managing
a 42-year-old patient diagnosed with this condition.
