Immune thrombocytopenia (ITP) is the most common cause of isolated thrombocytopenia in healthy people. ITP may rarely coexist with autoimmune thyroid disorders, which may indicate more complex defect in immune system. Primary ITP usually responds well to steroids and intravenous immunoglobulins. However, ITP may be difficult to treat when associated with thyroid autoimmune disorders. In such ca...
The presenting features, diagnostic evaluation, seasonal variation and management performed in 110 children with immune thrombocytopenic purpura (ITP) attending at two tertiary level hospitals were evaluated. A peak incidence of children with ITP was observed during the month of June, July and the first step was found in May and lowest in the month of October to December. Mean initial platelet ...
To investigate whether altered megakaryocyte morphology contributes to reduced platelet production in idiopathic thrombocytopenic purpura (ITP), ultrastructural analysis of megakaryocytes was performed in 11 ITP patients. Ultrastructural abnormalities compatible with (para-)apoptosis were present in 78% +/- 14% of ITP megakaryocytes, which could be reversed by in vivo treatment with prednisone ...
Immune thrombocytopenia (ITP) is a disease characterized by isolated thrombocytopenia. Abnormal effector T cell activation is an important mechanism in the pathogenesis of ITP. Regulatory T cells (Treg) have a strong immunosuppressive function for T cell activation and their importance in the pathophysiology and clinical treatment of ITP has been confirmed. Myeloid-derived suppressor cells (MDS...
A method for the measurement of immunoglobulin G associated with gel-filtered platelets is described and finding in 70 control subjects and 37 patients with immune thrombocytopenic purpura (ITP) are reported. Control platelet-associated IgG (PAIgG) levels (nanograms IgG per 10(9) platelets) averaged (+/-SD) 1231+/-424; samples studied after 24 and 48 hr remained within the control range. PAIgG ...
Health-related quality of life (HRQoL) is a major concern for adults with chronic immune thrombocytopenic purpura (ITP) due to the symptoms associated with the disease and its treatment. This study utilized the ITP-patient assessment questionnaire (ITP-PAQ), a specialized HRQoL questionnaire for ITP, to investigate the humanistic burden of ITP and the impact of romiplostim therapy on HRQoL in t...
Immune thrombocytopenic purpura (ITP) is characterized by a decreased platelet count caused by excess destruction of platelets and inadequate platelet production. In many cases, the etiology is not known, but the viral illness is thought to play a role in the development of some cases of ITP. The current (2011) American Society of Hematology ITP guidelines recommend initial diagnostic studies t...
BACKGROUND Patients with primary immune thrombocytopenia (ITP) commonly describe symptoms of fatigue. However, hematologists rarely consider fatigue a manifestation of ITP. OBJECTIVES To document the prevalence of fatigue among patients with ITP and to determine the patient characteristics that are associated with fatigue. Using a cross-sectional design, we surveyed 1871 members of the U...
In a phase 2 clinical trial of annual alemtuzumab for treatment of relapsing-remitting multiple sclerosis, 6 of 216 patients (2.8%) developed immune thrombocytopenia (ITP). Over mean follow-up of 4.5 years, the incidence rate of ITP was 6.2 (95% confidence interval, 2.3-13.3) per 1000 person-years. Median times from initial and last alemtuzumab exposure to ITP diagnosis were 24.5 and 10.5 month...
Guidelines for the Diagnosis and Treatment of Helicobacter pylori Infection in Korea was revised in 2013 and idiopathic thrombocytopenic purpura (ITP) was enlisted as a target for H. pylori eradication therapy with high level of evidence and strong recommendation grade. Clinical studies have steadily reported the rise of platelet count after H. pylori eradication roughly in a half of the patien...
