In the pathogenesis of thrombotic thrombocytopenic purpura (TTP), reductions in
the enzyme activity of ADAMTS13, which cuts ultralarge von Willebrand multimers,
generates shear stress on the microvascular endothelium, leading to platelet
aggregation and the formation of a thrombus. ADAMTS13 activity is markedly
decreased in typical TTP, but is only mildly reduced in secondary TTP, which
concomitantly develops with primary disease. The latter develops with septic
disseminated intravascular coagulation (DIC) and often causes organ failure.
Recombinant thrombomodulin (rTM) is a drug that is used to treat DIC and may also
remit TTP because it improves vascular endothelial dysfunction. Therefore, we
herein investigated the efficacy of rTM in patients treated for the pathology of
secondary TTP. Patients who were admitted to the Emergency and Critical Care
Center of our hospital and met the following conditions were extracted and
retrospectively analyzed: hemolytic anemia accompanied by fragmented red blood
cells (Hb?12?g/dL or lower); thrombocytopenia (<100?×?10/?L); and ADAMTS13
activity <50%. Sixteen patients were included and accompanied by Kidney Disease:
Improving Global Outcomes (KDIGO) stage 2 or more severe nephropathy and DIC.
Eleven and 5 patients treated with and without rTM (the rTM and non-rTM treatment
groups, respectively) were compared, and no significant difference was noted in
their basic characteristics, such as background disease and severity. No
significant difference was observed in survival rates; however, the platelet
count, which is an important outcome of treatments for TTP, significantly
increased in the rTM treatment group: 3.3?±?2.6?11.3?±?14.6 versus
3.5?±?3.7?5.7?±?3.9?(×1000/?L) (P = 0.034). Thrombotic thrombocytopenic purpura
originally requires invasive treatments and its prognosis is not favorable. Blood
thrombomodulin levels also markedly increase due to vascular endothelial
dysfunction, whereas rTM alleviates vascular endothelial dysfunction in TTP
patients with high blood TM levels, suggesting the importance of administering
rTM. Thus, rTM may be effective for secondary TTP and may be adopted as adjuvant
therapy.
