idiopathic purpura

Tao Xu, Ning Li, Fa Jin, Keren Wu, Zhipeng Ye
The study aimed to investigate the long-term outcomes of laparoscopic splenectomy (LS) in Chinese patients with chronic idiopathic thrombocytopenic purpura (ITP). This was a retrospective analysis of 114 patients with ITP who underwent LS from 2001 to 2013. Patients were classified according to response at last contact: complete response (CR), partial response (PR), and no response (NR). Patients with CR had the highest platelet levels and patients with NR had the lowest. A correlation was observed between postoperative peak platelet count and platelet count on 2-month postoperative (r=0...

OBJECTIVE: To identify the hematological manifestations and its association with serum ferritin levels in SLE patients from Western India. METHODS: Ninety clinically diagnosed SLE patients fulfilling ACR criteria were included. Disease activity was assessed at the time of evaluation using Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Sera were tested for serum ferritin levels by ELISA (Calbiotech, USA). Autoantibodies such as ANA, anti-dsDNA by indirect immunofluorescence test (IFA- Bio-Rad, USA) and anti-cardiolipin antibodies (ACA) to IgG and IgM isotypes and Anti-β2 GP antibodies to IgG and IgM isotypes were detected by ELISA using commercially available kits (Euroimmun, Lubeck, Germany)...

BACKGROUND: Thrombotic thrombocytopenic purpura is a rare thrombotic microangiopathy, related to a severe ADAMTS13 deficiency (a disintegrin and metalloprotease with thromboSpondin type 1 repeats, member 13; activity <10% of normal). Childhood-onset thrombotic thrombocytopenic purpura is very rare and initially often misdiagnosed, especially when ADAMTS13 deficiency is acquired (ie, not linked to inherited mutations of the ADAMTS13 gene). We aimed to investigate initial presentation, management, and outcome of acquired thrombotic thrombocytopenic purpura in children...

HIV complicates the diagnostic and therapeutic approaches to idiopathic thrombotic thrombocytopenic purpura (TTP), prompting debate in the literature regarding the benefit of plasma exchange versus simple plasma infusion. Herein we present a case of HIV-TTP, initially treated conservatively with plasma infusion but because of progressive neurologic decline, required urgent plasma exchange for resolution of hematologic derangements and neurologic sequelae. Based on the available literature, there appears to be a spectrum of HIV-associated TTP disorders...

Acquired thrombotic thrombocytopenic purpura is primarily caused by deficiency of plasma ADAMTS13 activity resulting from autoantibodies against ADAMTS13. However, ADAMTS13 deficiency alone is often not sufficient to cause acute thrombotic thrombocytopenic purpura. Infections or systemic inflammation may precede acute bursts of the disease but the underlying mechanisms are not fully understood. Here, 52 patients with acquired idiopathic thrombotic thrombocytopenic purpura and 30 blood donor controls were recruited for the study...

Angiosarcoma of the spleen is a rare malignancy that arises from vascular endothelial origin. This neoplasm is highly malignant and diagnosis is often delayed due to the vague presentation of clinical symptoms. A case report and concise review of the current diagnostic criteria and surgical treatment are provided to aid in the detection and treatment of this malignancy. We present a case of a 56-year-old female who presented with massive splenomegaly secondary to angiosarcoma of the spleen. The patient suffered from longstanding symptomatic anemia and thrombocytopenia...

Genetic risk factors predispose to thrombophilia and play the most important etiopathogenic role in venous thromboembolism (VTE) in people younger than 50 years old. At least one inherited risk factor could be found in about half of the cases with a first episode of idiopathic VTE.Roughly, genetic risk factors are classified into two main categories: loss of function mutations (such as deficiencies of antithrombin, protein C, protein S) and gain of function mutations, (such as prothrombin mutation G20210A, factor V Leiden)...

OBJECTIVES: Based on the concept of immune dysregulation in immune thrombocytopenic purpura (ITP) and that Interleukin-18 (IL-18) is an inflammatory cytokine that plays an important role in autoimmune disease by inducing interferon-γ secretion; this study aimed to assess a possible association between the IL-18 promoter polymorphisms (-607 C/A site) and genetic susceptibility to ITP and the impact of the immunoglobulins (Igs) concentrations level on disease severity and response to therapy...

An 80-year-old man was admitted to our hospital because of severe thrombocytopenia. He was diagnosed with idiopathic thrombocytopenia, and prednisolone together with eltrombopag was started, leading to significant improvement of platelet counts. Four years later, there was a prominent increase of peripheral blood monocytes, which was accompanied by recurrence of thrombocytopenia. Bone marrow aspirates and serum electrophoresis revealed coexistence of chronic myelomonocytic leukemia (CMML) and multiple myeloma (MM)...

Asplenic patients are at increased risk for sepsis and fulminant infection. Sepsis in these patients is typically secondary to encapsulated bacteria, with Streptococcus pneumoniae being the most frequent pathogen. Rare complications of severe sepsis include purpura fulminans and bilateral adrenal hemorrhage (Waterhouse-Friderichsen syndrome). We present the case of a 36-year-old woman, healthy except for splenectomy years prior for idiopathic thrombocytopenic purpura treatment, who presented with fever. Upon presentation to our hospital, three hours after symptoms onset, she had purpura fulminans and shock...

During the past year, many articles were published on the extragastric diseases related to Helicobacter pylori infection. This supports the theory that some microorganisms may cause diseases even far from the primary site of infection by interfering with different biologic processes. The role of H. pylori on idiopathic thrombocytopenic purpura, sideropenica anemia, and vitamin B12 deficiency is well known. On the other hand, there is a growing interest in the bacterium's association with cardiovascular, neurologic, hematologic, dermatologic, head and neck, and uro-gynecologic diseases, as well as diabetes mellitus and metabolic syndrome, with very promising results...

BACKGROUND: Thrombotic thrombocytopenic purpura (TTP) is a rare, episodic clinical syndrome involving the production of thrombi in the microvasculature accompanied by thrombocytopenia and symptoms of organ ischemia. Idiopathic TTP develops when a patient produces antibodies that react with the protease ADAMTS13. The course after an episode is unpredictable; patients may relapse frequently or never. There is no laboratory value that can reliably predict potential relapse. STUDY DESIGN AND METHODS: To assess diagnostic and predictive values for risk of relapse, plasma samples from 27 patients with idiopathic TTP in remission were analyzed for anti-ADAMTS13 immunoglobulin (Ig)G, ADAMTS13 activity, and ADAMTS13 inhibitor titer...

An 83-year-old woman was admitted to our hospital with a severe headache and purpura. She had previously been diagnosed with idiopathic thrombocytopenia purpura (ITP) and achieved complete remission with steroid therapy. Steroid therapy had been completed one week prior to the current admission. The recurrence of severe thrombocytopenia (<1.0×10(4) platelets/μl) was detected and a CT scan revealed pituitary hemorrhage without pituitary adenoma. She received steroid therapy combined with intravenous immunoglobulin, which resulted in the amelioration of ITP and improvements in the pituitary hemorrhage...

An 81-year-old man presenting with fever, neurological symptoms, thrombocytopenia, and hemolytic anemia was diagnosed with acquired idiopathic thrombotic thrombocytopenic purpura (TTP). His disintegrin-like and metalloproteinase with thrombospondin type 1 motifs 13 (ADAMTS13) activity was <1% and the ADAMTS13 inhibitor titer was 3.2 BU/ml. He received plasma exchange and steroid administration until remission was achieved. Seven months later, he suffered from paralysis of the right hand, hemolytic anemia, and thrombocytopenia...

Idiopathic thrombocytopenic purpura (ITP) is characterized by a diminished platelet count, an autoimmune condition with antibodies against platelets and an increased tendency to bleed. The association between ITP and solid tumors is uncommon. Cytokine-induced killer (CIK) cell therapy is a well tolerated and promising cancer treatment with minimal toxicity. For the first time, CIK cell therapy was reported to be followed by ITP. The mechanism through which CIK induces ITP remains unclear. Imbalanced ratio of Th cells, decreased numbers or impaired function of Treg cells and excessive secretion of cytokines inducing abnormal activation of B cells may be among the possible reasons...

BACKGROUND: Spleen surgery is a surgery without anastomosis and without the modification of the body's physiological circuits; therefore, the difference in the size of the incision between the laparoscopic and the open approach determines the main advantages of the laparoscopic surgery: small amounts of painkillers, reduced postoperative complication rate, low duration of hospitalization and reduced intra- and postoperative blood transfusion requirements. METHODS: Data from the medical records of 4 patients who underwent laparoscopic surgery were retrospectively analyzed...

Notch signalling is involved in the development of several autoimmune diseases, one of such diseases is ITP. The aim of this study was to investigate and compare the expression levels of Notch1 receptor and its target Hes1 gene in Egyptian paediatric ITP patients. Real-time quantitative reverse transcriptase polymerase chain reaction was used to analyse the expression levels of Notch1 and Hes1 in 42 children with primary ITP (22 newly diagnosed and 20 persistent) cases. Twenty age and sex matched non-ITP controls were included...

Concurrent association of idiopathic thrombocytopenic purpura (ITP) and peripheral neuropathy is a rare condition. There are only few case reports published concerning peripheral neuropathy with ITP. One of the etiopathogenetic mechanisms proposed is intraneural hemorrhage, but the pathogenesis is not fully understood. Autoimmune nature with common antibodies to the platelets and the nerve´s myelin sheath should also be considered. Here we describe a 47-year-old woman, with a family history of autoimmune diseases...
