Idiopathic thrombocytopenic purpura (ITP) is an autoimmune disease defined by a low platelet count secondary to accelerated platelet destruction by anti-platelet antibodies. The resulting bleeding diathesis can present a therapeutic dilemma. We have treated two cases of ITP in which ureteral stones were successfully extracted by transurethral ureterolithotripsy (TUL) and extracorporeal shock wa...

Recent reports have suggested an association between Helicobacter pylori infection and idiopathic thrombocytopenic purpura (ITP). The prevalence of H pylori infection and the effect of its eradication in a series of 30 ITP patients were investigated. H pylori infection has been documented in 13 patients (43.33%) by 13C urea breath test and confirmed by histologic examination. Bacterium eradicat...

Platelets are anuclear blood cells whose function is to form blood clots when we injure ourselves, to prevent excessive blood loss. Thrombocytopenia is a relative low number of platelets in the blood. Thrombocytopenia has several possible causes, including the trapping of platelets in spleen, reduced production of platelets and increased breakdown of platelets. Some examples of an increase in p...

Hematologic abnormali"es are generally present among systemic lupus erythematosus pa"ents. Idiopathic thrombocytopenic purpura can be the first manifesta"on of SLE, followed by other symptoms and signs of disease appearing several years later. Although bleeding due to immune thrombocytopenic purpura is usually mild and occurs in mucocutaneous surfaces, but it may be severe and represent in u...

Platelet-associated IgG (PAIgG) was measured by a simple radial immunodiffusion technique using washed solubilized platelets and commercially available immunoplates. Subjects with normal platelet counts had PAIgG levels of 1.5--7.0 fg/platelet. Subjects with idiopathic immune thrombocytopenic purpura (ITP) had levels ranging from 5.7 to 70.5 fg/platelet. All patients with recurrent ITP and 85% ...

Background: Bernard-Soulier syndrome (BSS) is a rare, autosomal recessive platelet function disorder which is commonly mistaken for idiopathic thrombocytopenic purpura (ITP).The report includes seven cases of BSS that have been diagnosed and treated as ITP for a long time. Methods: Between 2006 and 2016, data of seven BSS patients who have long been diagnosed and treated as ITP were collected ...

primary immune thrombocytopenia is an acquired bleeding disorder with no clinically apparent cause of thrombocytopenia. clinical indicators of itp include easy bruising of the skin, prolonged bleeding on injury, mucocutaneous lesions such as petechiae and ecchymosis, epistaxis, gastrointestinal bleeding, hematuria and bleeding from the gums. it is important for a dentist to be aware of the clin...

coincidence of autoimmune diseases such as immune thrombocytopenic purpura (itp) with  immunodeficiencies has  been  reported  previously in  patients  who  suffered  from primary antibody deficiency (pad). but there is no original study on immunological profiles of itp patients to find out their probable immune deficiency. in this case-control study, itp patients’ humoral immunity was investig...
