OBJECTIVE
To investigate the response of HIV-associated severe thrombocytopenia (STP) to highly active antiretroviral therapy (HAART) including protease-inhibitors.
METHODS
In this retrospective study, 15 patients with HIV-associated STP (platelet count < 50 x 10(9)/l mostly antiretroviral
The Wiskott-Aldrich syndrome (WAS) is an inherited platelet/T-lymphocyte disease characterized by small platelets, thrombocytopenia and immunodeficiency. Because degradative events have a significant role, we directly examined calpain (Ca(2+)-dependent neutral protease), a prominent protease in the
Infantile or congenital cases of thrombotic microangiopathy have been reported that were familial and characterized by ongoing microangiopathic hemolysis and thrombocytopenia in the absence of regular fresh-frozen plasma transfusions. The authors describe a child with congenital microangiopathic
Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by the SFTS virus (SFTSV), which has a high mortality rate. Currently, no licensed vaccines or therapeutic agents have been approved for use against SFTSV infection. Here, we report that the cholesterol,
Heparin-induced thrombocytopenia (HIT) is due to immunoglobulin G (IgG) antibodies, which bind platelet factor 4 (PF4) modified by polyanions, such as heparin (H). IgG/PF4/polyanion complexes directly activate platelets via Fc gamma type 2 receptor A (FcγRIIA) receptors. A bacterial protease,
Platelet function of immune thrombocytopenia (ITP) has been controversial because of methodological problems associated with low platelet counts. In this study, we evaluated platelet function in 21 patients with chronic ITP (cITP) using the recently developed flow cytometry (FCM)-based platelet
Patient A.F. is a 28-year-old polytransfused woman with an inherited bleeding disorder, Glanzmann's thrombasthenia. An abnormal platelet function is linked to severe decreases in the platelet content of the integrins GP IIb and GP IIIa. In 1987 the patient gave birth to a child with severe anemia
Heparin-induced thrombocytopenia and thrombosis is a severe immune-mediated adverse drug effect caused by the IgG antibodies to platelet factor4/heparin complexes. Activated platelets, vascular endothelium, and monocytes generate the life-threatening thrombocytopenia and thrombosis. In this review,
Thrombocytopenia is a relatively frequent hematological complication in patients infected with the human immunodeficiency virus type 1. Occurring in all risk groups (homosexuals, intravenous drug addicts, hemophiliacs, heterosexuals) this complication has an overall prevalence varying between 5 and
Congenital thrombotic thrombocytopenic purpura (TTP) is an inherited form of TTP due to the deficiency of von Willebrand factor (vWF) cleaving protease ADAMTS13. The authors describe two children with congenital TTP who presented with thrombocytopenia, hemolytic anemia, elevated LDH levels, and
Recent studies investigating thrombotic thrombocytopenic purpura (TTP) have implicated abnormal plasma von Willebrand factor (vWF)-cleaving metalloprotease activity in this disorder. It has been proposed that a metalloprotease cleaves unusually large (UL) multimers of vWF, which enter the
MALT lymphoma-translocation protein 1 (Malt1) protease activity is triggered by stimulation of various immune receptors. Activation of Malt1 protease induces cleavage of negative regulators for immune responses, resulting in lymphocytes activation. Although Malt1 protease mediates the signaling
BACKGROUND
Cytotoxic T lymphocytes from donors are thought to injure the target organs in post-transfusion graft-versus-host disease (PT-GVHD) through perforin-granzyme- and Fas-dependent cell killings. The protease involved is a serine protease, and nafmostat mesilate (NM), a serine protease
