Excerpt:"Thrombocytopenia is one of the most frequent causes
for hematologic consultation in the practice of medicine, and potentially
one of the most life-threatening. Although the normal platelet count
in humans (150–400 x 109/L)
far exceeds the minimal level required to avoid pathologic hemorrhage
(<50 x 109/L), a
number of medical conditions cause either increased destruction
or reduced production of platelets, increasing the risk of pathologic
bleeding. This chapter discusses an approach to the diagnosis of thrombocytopenia,
grouping various causes by mechanism of action, and describing our
current understanding of pathogenesis, treatment, and prognostication.
In the vast majority of patients, a cause for thrombocytopenia can
be identified, and effective therapy instituted.Abbreviations and acronyms that
appear in this chapter include: ADAMTS, a disintegrin and metalloproteinase
with thrombospondin repeats; ALL, acute lymphocytic leukemia; APLA,
antiphospholipid antibody; APS, antiphospholipid antibody syndrome; CAMT,
congenital amegakaryocytic thrombocytopenia; CTP, cyclic thrombocytopenia;
DIC, disseminated intravascular coagulation; EDTA, ethylenediaminetetraacetic
acid;..."
