    Full Text Available CONTEXT: Neonatal alloimmune thrombocytopenic purpura (NAITP is a neonatal disorder characterized by maternal alloimmunization against fetal platelet antigens inherited from the father. Intracranial hemorrhage leading to death or permanent neurological disability may occur in the fetus. CASE REPORT: A healthy 30-year-old woman gave birth to her first baby by cesarean after an uneventful 36-week pregnancy. Ten hours after birth, the infant presented severe petechiae, with platelet count of 8 x 10³/µl. The mother’s platelet count was normal (180 x 10³/µl. The infant received intravenous immunoglobulin and was discharged 18 days later, with platelet count of 100 x 10³/µl. The cause of thrombocytopenia was not elucidated at that time. One year later, the infant died of neuroblastoma. Since the parents wanted another child, they were referred for investigation of this thrombocytopenia. Platelet genotyping and platelet antibody screening were performed, showing total HPA-1 system mismatch between mother (HPA-1b1b and father (HPA-1a1a, with anti-HPA-1a antibodies in the mother’s serum. We concluded that the first baby was born with NAITP. Thus, in the second pregnancy, the mother was treated with several infusions of intravenous immunoglobulin. Careful ultrasound monitoring was performed, with normal results for mother and fetus throughout the pregnancy. The second baby was born by cesarean at 39 weeks, presenting 92x10³ platelets/µl six hours after birth. The baby’s platelets were genotyped as HPA-1a1b and the mother’s serum again showed anti-HPA-1a antibodies. No clinical bleeding was observed. Intravenous immunoglobulin therapy was an effective treatment for preventing NAITP in the second baby.

    A 34-year-old woman presented with the clinical and laboratory features of thrombotic thrombocytopenic purpura (TTP). Studies with isologous platelets labelled with 111 In-oxine revealed a short half-life or circulating platelets (18,5 hours) and destruction of the transfused platelets in the spleen, liver and bone marrow. There was no scintigraphic evidence of deposition of labelled platelets in the vasculature. The patient was treated with daily fresh frozen plasma transfusions, but no improvement in platelet count or serum urea level was noted. Although there was no clinical evidence of a bleeding tendency at the time, the patient had a fatal cerebrovascular haemorrhage. The findings in this case suggest that an immune type destruction of platelets may occur in TTP

    Full Text Available Idiopathic thrombocytopenic purpura (ITP is defined as a hematologic disorder, characterized by isolated thrombocytopenia without a clinically apparent cause. The major causes of accelerated platelet consumption include immune thrombocytopenia, decreased bone marrow production, and increased splenic sequestration. The clinical presentation may be acute with severe bleeding, or insidious with slow development with mild or no symptoms. The initial laboratory tests useful at the first visit to predict future diagnosis were erythrocyte count, leukocyte count, anti-glycoprotein IIb/IIIa antibodies, reticulated platelets, plasma thrombopoietin level. Treatment should be restricted to those patients with moderate or severe thrombocytopenia who are bleeding or at risk of bleeding. We present a case report on ITP with clinical presentation, diagnosis and management.

    Full Text Available ABSTRACT This essay is based on a medical case of idiopathic thrombocytopenic purpura (ITP during pregnancy. The cause of ITP is unknown, who suffer from this disorder, generate antibodies that destroy thrombocytes from their blood. ITP affects women of childbearing age and is associated to maternal and fetal complications. The management of a pregnant patient is difficult and requires the combined care of an obstetrician, a hematologist, and a neonatologist. The main therapeutic options for ITP in pregnant women include glucocorticoids and intravenous immunoglobulin. Splenectomy may be (performed in refractory cases. There is no concerning the management and treatment of pregnant women.

    Full Text Available The first documented case of thrombotic thrombocytopenic purpura (TTP associated with pneumococcal septicemia is reported. This association has been previously demonstrated with hemolytic uremic syndrome. The patient presented with recurrent seizures, oliguric renal failure, fever, thrombocytopenia and microangiopathic hemolytic anemia; coagulation studies were normal. Blood and sputum cultures were positive for Streptococcus pneumoniae. The patient responded to therapy with plasmapheresis and antiplatelet agents as well as antibiotics. Coincident infection should be searched for in all cases of TTP.

    Full Text Available Immune thrombocytopenic purpura is an acute, generally considered a self-limiting benign disorder with a 60%-80% change of spontaneous recovery occurring usually within a few months after onset. Intracranial hemorrhage is a rare but life-threatening complication of childhood immune thrombocytopenic purpura. We report a 4-year-old girl who admitted with headache, vomiting, bleeding from noise and bruises on the extremities. Her neurological examination was normal. Based on laboratory finding she was diagnosed immune thrombocytopenic purpura and intracranial hemorrhage. We suggest that cranial imaging should be perform in patients with immune thrombocytopenic purpura admitted with bleeding symptoms, vomiting and headache even if they had no abnormal neurological signs.

    : Thrombocytopenia, in the setting of microangiopathic hemolytic anemia and thrombotic events, is characteristic of both thrombotic thrombocytopenic purpura and primary antiphospholipid syndrome. Clinically, it is difficult to distinguish between these two syndromes. We present a 41-year-old woman with chronic, relapsing thrombotic thrombocytopenic purpura in the presence of antiphospholipid antibodies. She had clinical manifestations of antiphospholipid syndrome without meeting laboratory criteria of the Sydney classification system. In the literature, there have only been nine cases of thrombotic thrombocytopenic purpura associated with primary antiphospholipid syndrome. Seven of the nine cases suffered from one or multiple strokes, a common feature in antiphospholipid syndrome, but an uncommon finding in thrombotic thrombocytopenic purpura. We introduce the possibility of an association between thrombotic thrombocytopenic purpura and the presence of antiphospholipid antibodies. Systematic testing of ADAMTS13 activity and anti-ADAMTS13 antibodies in patients who present with neurological symptoms and thrombocytopenia, in the presence of antiphospholipid antibodies, may help with the diagnosis of the rare thrombotic thrombocytopenic purpura-antiphospholipid syndrome combination.

    Full Text Available Immune thrombocytopenic purpura (ITP, also known as idiopathic thrombocytopenic purpura, is an acquired immune-mediated disease of adults and children characterized by a transient or persistent decrease of platelets and, depending upon the degree of thrombocytopenia, an increased risk of bleeding. The use of standard treatments for acute myocardial infarction (AMI, such as antiplatelet agents and anticoagulants, pose serious problems in patients with ITP due to the potential higher risk of bleeding complications. There are no current guidelines available for management of ITP patients with AMI. In this brief review of the limited available literature, we discuss the proposed pathophysiological link between ITP and arterial thrombosis and the challenging medical and interventional treatment of these patients.

    Thrombotic thrombocytopenic purpura is an acute syndrome with abnormalities in multiple organ systems, which becomes manifest with microangiopathic hemolytic anemia and thrombocytopenia. The hereditary or acquired deficiency of ADAMTS-13 activity leads to an excess of high molecular weight von Willebrand factor multimers in plasma, leading to platelet aggregation and diffuse intravascular thrombus formation, resulting in thrombotic thrombocytopenic purpura. Thrombotic lesions occurring in TTP leads to ischemia and convulsion. Depending on the properties of the bony tissue, fractures are divided into three groups as traumatic, pathological, and stress fractures. A pathologic fracture is a broken bone caused by disease leading to weakness of the bone. This process is most commonly due to osteoporosis, but may also be due to other pathologies such as cancer, infections, inherited bone disorders, or a bone cyst. We herein report a case with a pathologic fracture due to convulsion secondary to thrombotic thrombocytopenic pupura. Thrombotic lesions occurring in TTP may lead to ischemia and convulsion, as in our patient and pathological fractures presented in our case report may occur as a result of severe muscle contractions associated with convulsive activity. Thrombotic thrombocytopenic pupura is a disease that involves many organ systems and thus may have a very wide spectrum of clinical presentations. Copyright © 2014. Published by Elsevier Ltd.

    Accessory spleens were sought in 28 patients who had undergone splenectomy for chronic idiopathic thrombocytopenic purpura (ITP), using a variety of techniques. Abdominal scintigraphy with autologous erythrocytes labeled with Tc-99m and opsonized with anit-D IgG (radioimmune method) proved to be most useful, clearly demonstrating one or more accessory spleens in 12 cases (43%). Computed tomography (CT) was also helpful. Four out of five patients demonstrated an increased platelet count following surgery, the effectiveness of which was illustrated by the radioimmune scan. Patients who have had splenectomy for chronic ITP should be scanned using radioimmune techniques and CT to determine whether an accessory spleen is present

    Full Text Available We present a case of glatiramer acetate-associated refractory immune thrombocytopenic purpura (ITP in a female patient with multiple sclerosis. A search of MEDLINE/PubMed did not find any connection between glatiramer acetate and thrombocytopenia, specifically ITP. The autoimmune reaction was resistant to conservative ITP treatment, and was eventually managed only by splenectomy. To the best of our knowledge, this is the first report of glatiramer acetate-associated ITP. Physicians should be aware of this condition, and consider performing routine blood counts at the beginning of glatiramer acetate treatment.

In acquired TTP, especially in secondary TTP with various underlying diseases, the diagnosis is difficult because there are many cases that do not exhibit severe deficiency of ADAMTS13 or raised levels of ADAMST13 inhibitors. It is well known that collagen disease, malignancy, and hematopoietic stem cell transplantation can be underlying conditions that induce TTP. However, TTP induced by acute pancreatitis, as experienced by our patient, has rarely been reported. Our patient completely recovered with treatments using steroids and plasma exchange (PE only. In cases where patients develop acute pancreatitis with no apparent causes for hemolytic anemia and thrombocytopenia, the possibility of TTP should be considered. Treatments for TTP including PE should be evaluated as soon as a diagnosis is made.Keywords: thrombotic thrombocytopenic purpura, ADAMTS13, acute pancreatitis, plasma exchange

    Immune Thrombocytopenic Purpura (ITP) is a common autoimmune bleeding disorder characterized by a reduction in peripheral blood platelet counts. In this disease, autoantibodies (Auto-Abs) are produced against platelet GPIIb/GPIIIa by B cells, which require interaction with T cells. In this review, the importance of B and T lymphocytes in ITP prognosis has been studied. Relevant literature was identified by a PubMed search (1990-2016) of English-language papers using the terms B and T lymphocyte, platelet, CD markers and immune thrombocytopenic purpura. T and B lymphocytes are the main immune cells in the body. Defective function causes disrupted balance of different subgroups of lymphocytes, and abnormal expression of surface markers of these cells results in self-tolerance dysfunction, as well as induction of Auto-Abs against platelet glycoproteins (PG). Given the role of B and T cells in production of autoantibodies against PG, it can be stated that the detection of changes in CD markers' expression in these cells can be a good approach for assessing prognosis in ITP patients. © 2017 APMIS.

  5. Treatment of immune thrombocytopenic purpura: focus on eltrombopag

    Full Text Available Lawrence RiceWeill Cornell Medical College, The Methodist Hospital, Houston, Texas, USAAbstract: Immune thrombocytopenic purpura (ITP is a relatively common autoimmune disorder in which antibodies are produced to circulating platelets. Symptoms can be mild, but for most patients the risk of severe bleeding is unacceptable and treatment is required. Glucocorticoids followed by splenectomy had been the mainstays of therapy. High dose intravenous immunoglobulin and anti-RhD therapy are available for patients with severe illness, but produce only temporary benefit. Rituximab may provide more durable responses, danazol may be underutilized, and immunosuppressants and cytotoxic agents are less often required. Recently the pathophysiology of ITP has been more clearly elucidated, particularly the importance of decreased production of platelets in most patients and the very blunted rise that occurs in serum thrombopoietin (TPO. The isolation of TPO and better understanding of its role in thrombopoiesis has led to the development of new highly effective treatments. TPO analogs had some successes in treating highly refractory ITP patients but were taken out of development due to TPO-antibody induction. Two second-generation TPO-mimetics, romiplostim and the orally available eltrombopag, have recently been licensed in some territories for the treatment of ITP. Approval of eltrombopag was based on results from Phase II and III placebo-controlled clinical trials and a long-term extension study. About 80% of patients achieve significant increases in platelet count (11% of placebo patients, with reduced bleeding and reduced use of concomitant medications; responses are often durable with no tachyphylaxis. The side effects of eltrombopag are generally mild and not worse than placebo, although there are concerns about hepatic dysfunction, and the potentials for thromboses, marrow reticulin fibrosis, rebound thrombocytopenia and cataracts.

    Abstract Thrombotic thrombocytopenic purpura (TTP) is a part of a spectrum of thrombotic microangiopathy syndromes which are mainly characterized by platelet aggregation causing microangiopathic hemolytic anemia, thrombocytopenia and microvascular occlusion. In literature, very few cases expressing a direct association between pre-existing Grave’s disease and TTP have been described. A 37-year-old African–American woman with past medical history of Grave’s disease and polysubstance abuse who presented with complaints of dyspnoea at rest and chest pain was diagnosed to have TTP on further evaluation. Patient also showed severely elevated thyroid hormones and suppressed thyroid stimulating hormone levels indicating severe thyrotoxicosis. Initiation of prompt management of TTP and thyrotoxicosis led to a favorable patient outcome. In conclusion, patients presenting with thyrotoxicosis, thrombocytopenia and microangioapthic hemolytic anemia without an alternative cause should be treated and screened for TTP due to the high fatality associated with untreated or untimely detection of this disease.

    Treatment of chronic immune (idiopathic) thrombocytopenic purpura with corticosteroids and/or splenectomy results in safe platelet counts in over 70% of patients without additional treatment. Therapy of patients who are refractory to these two treatments may be difficult. The treatment approach to refractory ITP patients, described in this report, is arbitrarily divided into four levels: levels 1 through 3 represent treatments with increasing side effects; level 4 therapy may be tried when the others have failed. Patients undergoing these treatments may require concomitant intravenous gammaglobulin, high-dose corticosteroids or platelets, to maintain the platelet count in the setting of mucosal bleeding or severe thrombocytopenia.

    Acquired thrombotic thrombocytopenic purpura is primarily caused by the 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. Herein, 52 patients with acquired autoimmune thrombotic thrombocytopenic purpura and 30 blood donor controls were recruited for the study. The plasma levels of human neutrophil peptides 1-3 and complement activation fragments (i.e. Bb, iC3b, C4d, and sC5b-9) were determined by enzyme-linked immunosorbent assays. Univariate analyses were performed to determine the correlation between each biomarker and clinical outcomes. We found that the plasma levels of human neutrophil peptides 1-3 and Bb in patients with acute thrombotic thrombocytopenic purpura were significantly higher than those in the control (Ppurpura patients and the control. We conclude that innate immunity, i.e. neutrophil and complement activation via the alternative pathway, may play a role in the pathogenesis of acute autoimmune thrombotic thrombocytopenic purpura, and a therapy targeted at these pathways may be considered in a subset of these patients.

    1985-01-01

    Evaluations were performed in 20 patients with childhood idiopathic thrombocytopenic purpura (ITP) who remained in remission longer than 12 months. The mean duration of follow-up from diagnosis was 39 months (range 17 to 87 months). Eleven patients (four girls) in group 1 had an acute course of ITP, defined as platelet count greater than 150 X 10(9)/L within 6 months of diagnosis. Nine patients (five girls) in group 2 had a chronic course, defined as platelet count less than 150 X 10(9)/L for greater than or equal to 1 year or requiring splenectomy in an attempt to control hemorrhagic symptoms. Platelet count and serum (indirect) platelet-associated IgG (PAIgG) levels were normal in all 20 patients at follow-up. Both direct and indirect PAIgG levels were measured using a 125 I-monoclonal anti-IgG antiglobulin assay. All had normal direct PAIgG levels, except for one patient in group 1 who had a borderline elevated value of 1209 molecules per platelet. These data suggest that the prevalence of elevated platelet antibodies is low during sustained remission without medication in patients with a history of childhood ITP. These data may be relevant for pregnant women with a history of childhood ITP, with regard to the risk of delivering an infant with thrombocytopenia secondary to transplacental passage of maternal platelet antibody

He was later diagnosed with thrombotic thrombocytopenic purpura (TTP based on the fact that he presented with most components of the TTP pentad (except for fever, which included altered mental status, acute kidney injury, thrombocytopenia, and evidence of red cell fragmentation and his ADAMTS13 level was found to be less than 10% prior to therapy. The patient then received plasma exchange, oral corticosteroids, and hemodialysis, which led to a full recovery of platelet count and renal function.

    Full Text Available Immune thrombocytopenic purpura (ITP is a rare complication after liver transplantation. Infection with cytomegalovirus (CMV is a frequent complication of organ transplantation and may induce autoimmune diseases, such as ITP. We report a case of ITP after primary CMV infection in a 3-year-old boy recipient of living-related orthotopic liver transplantation (OLT. The ITP developed 2 years after OLT in this patient who had received tacrolimus as an immunosuppressive agent, with nadir platelet counts of 5000/mm3 in 2 weeks. The patient was treated with two courses of intravenous gamma globulin (1 g/kg/day for 2 days and subsequent oral prednisolone (1.3 mg/kg/day for 2 weeks. He recovered from thrombocytopenia 4 weeks later. An inadequate immunosuppression, as evident by the low serum tacrolimus level (5.8 ng/mL before the episode of ITP in this patient, may allow the development of ITP after CMV infection.

    Full Text Available Pulmonary hyalinizing granuloma (PHG is a rare, benign lung disease of unknown etiology. It manifests as discrete, rounded nodules within the lung parenchyma. A 39-year-old woman presented for investigation after pulmonary nodules were found incidentally. Chest computed tomography showed multiple, discrete, non-enhancing pulmonary nodules bilaterally. Positron emission tomography (PET was negative. Biopsy demonstrated a non-specific lymphoplasmacytic infiltrate. Open resection yielded two nodules consistent with hyalinizing granulomas. The differential for multiple pulmonary nodules is broad. PET scan can help rule out metastatic disease, although some cancers are not hypermetabolic on PET. Furthermore, some non-malignant conditions, including hyalinizing granuloma, can show increased activity on PET. PHG should be included in the differential of multiple pulmonary nodules, especially if nodule stability can be demonstrated and/or needle biopsies are non-diagnostic. Associated immune-mediated conditions, such as idiopathic thrombocytopenic purpura (ITP in our patient, may also favor HG. In this case report we find an association between PHG and ITP.

    Basic principles in the therapy of chronic idiopathic thrombocytopenic purpura are glucocorticoides and splenectomy. Other measures: Intravenous high doses gamma globulin therapy, attenuated androgenes, immunosupresive drugs and plasmaferesis are less effective. During the period of 1989-1992 we treated 34 patients. From 34 patients, 23 were women and 11 were men. We treated patients primarily by prednisolon approximaly for 2 - 4 weeks. Rarely we use doses of 3 mg/kg per day for short periods of time (5 to 10 days) or "pulse therapy" of 500 mg per day. Those doses may be effective in elevating platelet count if the response is poor. If response occurs, high dosages of steroides should be tareped to determine the amount that will maintain the platelet count in the range of 30x10(9)/l to 50x10(9)/l (to minimaze the toxic sade effects of steroides). If steroides are ineffective, we perform splenectomy. From 34 treated patients by glucocorticoides, in 16 we got remission and in 11 partial response. We discussed in detailes relationship duration of treatment with glucocorticoides and level of platelets, and also correlation duration of treatment with prognosis. From 6 splenectomized patients 3 were successful. In two patients we applied intravenous gamma globulin therapy and attenuated androgen successfuly. In one patients therapy with gamma globulin, immunosupresive drugs, androgen and other measures was ineffective. In one patients without splenectomy we administrated successfuly gamma globulin therapy and androgen for peroid of two years.

    Full Text Available Introduction. Acquired thrombotic thrombocytopenic purpura (TTP has been associated with different autoimmune disorders. However, its association with pernicious anemia is rarely reported. Case Report. A 46-year-old male presented with blood in sputum and urine for one day. The vitals were stable. The physical examination was significant for icterus. Lab tests’ results revealed leukocytosis, macrocytic anemia, severe thrombocytopenia, renal dysfunction, and unconjugated hyperbilirubinemia. He had an elevated LDH, low haptoglobin levels with many schistocytes, nucleated RBCs, and reticulocytes on peripheral smear. Low ADAMTS13 activity (<10% with elevated ADAMTS13 antibody clinched the diagnosis of severe acquired TTP, and plasmapheresis was started. There was an initial improvement in his hematological markers, which were however not sustained on discontinuation of plasmapheresis. For his refractory TTP, he was resumed on daily plasmapheresis and Rituximab was started. Furthermore, the initial serum Vitamin B12 and reticulocyte index were low in the presence of anti-intrinsic factor antibody. So with the concomitant diagnosis of pernicious anemia, Vitamin B12 was supplemented. The rest of the immunological workups were negative. Subsequently, his symptoms resolved and his hematological parameters improved. Discussion. While pernicious anemia can masquerade as TTP, an actual association between the two can also occur and needs further evaluation and characterization.

    2014-06-01

    Full Text Available A 46-year-old female presented to the emergency room due to the chief complaint of left-sided weakness. By imaging study, she was diagnosed with cerebral infarction. Thrombolytic and antiplatelet agents were not considered due to the “golden hour” for treatment having passed and a low platelet count. The peripheral blood smear, bone marrow biopsy, and aspirate findings were consistent with immune thrombocytopenic purpura. The chromosome analysis revealed the 47,XXX karyotype. To the best of our knowledge, this is the first case report associated with the comorbidities of cerebral infarction, idiopathic thrombocytopenic purpura, and triple X syndrome.

    2002-07-01

    Full Text Available Background. Treatment of thrombotic thrombocytopenic purpura (TTP with plasma exchange (PE has reduced mortality rates from 90% in untreated patients to less than 20%. Despite primary effective PE, relapses occur in up to 40% of patients. Beside PE, second line treatment options are corticosteroids, vincristine, defibrotide, prostacycline. We describe two patients with relapsing TTP treated successfully with splenectomy.Patients and methods. Case 1. A 20–year female was diagnosed in October 2000 with idiopathic chronic relapsing TTP. First episode of PE plus methylprednisolone treatment led to complet remission. Subsequent relapses occured 3, 6 and 8 months after first TTP episode. Every relaps was effectivelly treated with PE and methylprednisolone. Because of more and more frequent TTP relapses laparoscopic splenectomy was performed. Currently, 7 months after splenectomy she is in complet TTP remission.Case 2. A 18–year female, was diagnosed in January 1997 with idiopathic TTP. After PE and methylprednisolone complete remission was established. Relaps occured after nearly three years. Later on, TTP got chronic course with neurological clinical symptoms and plateled drops as soon as PE treatment was withdrawn. Besides PE and methylprednisolone she received also defibrotide. Because of chronic, PE dependant TTP, laparoscopic splenectomy was performed. Today, 15 months after splenectomy she is in complete TTP remission.Conclusions. In idiopathic relapsing and chronic TTP, PE treatment only is usually not sufficient for durable remission. Second line TTP treatment drugs have limited efficacy. Based on our experience in patients with relapsing and/or chronic TTP, laparoscopic splenectomy should be considered as a first treatment option, especialy in junger patients.

    The diagnosis of thrombotic thrombocytopenic purpura is one of the possible diagnosis when a patient is admitted with unexpected micro-angiopathic hemolytic anemia and thrombocytopenia. The combination of sickle cell/β(+)-thalassemia and thrombotic thrombocytopenic purpura is rare and triggering. This article describes the poor outcome of a patient with sickle cell/β(+)-thalassemia presenting with gingival bleeding, severe thrombocytopenia and anemia. The patient had normal renal function, no neurological deficit and he was initially treated as immune thrombocytopenic purpura. He eventually died due to multi-organ failure and brain hemorrhage even though he had started plasma exchange sessions. The co-existence of thrombotic thrombocytopenic purpura and sickle cell anemia is making the diagnosis of the former difficult. Early and rapid intervention is critical to the outcome.

    Labelling platelets with 111 Indium-oxine has advantages over the conventional 51 chromium method: labelling is more efficient and the radiations emitted almost exclusively consist of gamma-rays. Owing to these advantages, autologous platelets can be used for kinetic studies in patients with idiopathic thrombocytopenic purpura, even when thrombocytopenia is severe. 111 Indium labelling also provides accurate information on the sites of platelet destruction, which may help to predict the patient's response to splenectomy [fr

    Kleine-Levin syndrome is an extremely rare neurological entity characterized by recurrent episodes of hypersomnia which are sometimes associated with compulsive hyperphagia and behavioral changes. Autoimmunity has recently been proposed as a factor contributing to its pathogenesis. Immune thrombocytopenic purpura is a relatively common autoimmune disease showing a lot of complexity and uncertainty regarding its treatment regimens and its refractory nature in some cases. A 32-year-old Persian White man visited his private hematologist complaining of recent episodes of epistaxis and appearance of petechial lesions 24 hours after receiving a meningococcal vaccine. He had a history of immune thrombocytopenic purpura 13 years before his presentation. Based on his history and laboratory findings, his condition was diagnosed as a relapse of immune thrombocytopenic purpura and was managed accordingly. He did not respond to first-line corticosteroid regimens and later developed neurological symptoms as recurrent episodes of hypersomnia and hyperphagia. After a complete clinical and paraclinical evaluation and ruling out other possible conditions, he was given a diagnosis of Kleine-Levin syndrome. He was followed up for his immune thrombocytopenic purpura and received different treatment regimens none of which were adequately successful except intravenous immunoglobulin that was only temporarily effective. He has had 4 documented self-limited episodes of Kleine-Levin syndrome since his initial presentation. Immune thrombocytopenic purpura may be associated with meningococcal vaccination in adulthood. Responses to treatment in immune thrombocytopenic purpura vary among patients. Our patient only had a transient acceptable response to intravenous immunoglobulin while all other options failed to improve his platelet count. Concurrence of immune thrombocytopenic purpura and Kleine-Levin syndrome supports the role of autoimmunity as the proposed pathophysiological mechanism of

    Thrombotic thrombocytopenic purpura (TTP) is a hematologic disease involving the platelet aggregation and resulting in hemolytic anemia, thrombocytopenia, and microvascular occlusion. Although frequent neurologic features are headache and confusion, focal deficit is described in 30% of the cases. There are a lot of causes inducing thrombotic thrombocytopenic, but reports are lacking when associated with Grave disease. We describe the case of a 51-year-old Caucasian woman presenting a 24-hour story of sudden onset of dysarthria and left superior limb palsy. Four months before, she developed severe hyperthyroidism associated with petechiae, hemolytic anemia, thrombocytopenia, and schistocytes at blood film examination. Relapse of TTP in association with Grave disease was diagnosed. There are few reports describing association between Grave disease and TTP with only mild neurologic involvement. We described, to our knowledge, the first case of acute ischemic stroke secondary to thrombotic thrombocytopenic induced by thyrotoxicosis. Copyright © 2014 National Stroke Association.

    We present the 15th case reported worldwide and 3rd case reported in Latin America of immune thrombocytopenic purpura associated with Type 1 diabetes mellitus in Scopus, MEDLINE, and SciELO. An 11-year-old male patient of mixed ethnicity with immune thrombocytopenic purpura, Type 1 diabetes mellitus, and gastritis due to H. pylori presented to the emergency room with petechiae, ecchymosis, and gingival and conjunctival bleeding that had been worsening for the past three months. The patient had a body mass index of 18.85 kg/m(2) (P75). A biochemical analysis showed 1×10(9) platelets/L, increased prothrombin time, increased partial thromboplastin time, and an HbA1C of 7.84% on admission. He was prescribed a single dose of intravenous methylprednisolone 750 mg in 100 mL of NaCl and daily oral 50 mg prednisolone, with intravenous 250 mg tranexamic acid every eight hours. The patient's glycemic control was continued with the administration of insulin glargine (30 units every 24 hours) and prandial insulin glulisine (five to eight units per meal). Before admission, the patient was on a prescribed treatment of sitagliptin 50 mg and metformin 850 mg, but this was suspended in the emergency room. For the eradication of H. pylori he was prescribed amoxicillin 500 mg every eight hours, oral clarithromycin 335 mg every 12 hours, and IV omeprazole 40 mg. After 15 days, he showed disease resolution and he was discharged to his home with orders to follow-up with pediatrics, hematology, and endocrinology services. The first-line treatment for immune thrombocytopenic purpura patients with active bleeding and a platelet count < 30,000 platelets/μl is the administration of corticosteroids and inmunoglobulin.

    Between 1972 and 1985, 107 patients with chronic Idiopathic Thrombocytopenic Purpura underwent splenectomy. Platelet life span and sites of sequestration were studied with labelled platelets and external scanning. Medical treatment was always of scarce and transient effectiveness and had considerable side effects. Splenectomy had minimal complications and mortality and caused no hazard of overwhelming sepsis in adults. The results of splenectomy were very satisfying, especially when platelet sequestration was mainly splenic (remission in about 90% of patients).

Recently, during the course of investigation, she was found to have incidental asymptomatic multiple pulmonary nodules on chest CT. Following a needle biopsy to exclude malignancy, 2 nodules were excised and were histologically confirmed as pulmonary hyalinizing granuloma PHG. The remaining 2 nodules regressed on increasing her dose of steroids. The case is discussed with emphasis on the histological and radiological differential diagnosis, in addition to including ITP among the spectrum of immunologic conditions associated with PHG.

    We report the case of a 68-year-old man who was diagnosed with Fournier's gangrene (FG), which developed during immunosuppresive treatment for idiopathic thrombocytopenic purpura (ITP). The patient was administered steroids for ITP but on the 36th day, he developed FG and septic shock. We initiated antibiotic treatment and drained a periproctal abscess immediately. On day 53, extensive drainage to progressive FG and a splenectomy was performed, following which both FG and thrombocytopenia improved. This is the first case of FG has developing in a ITP patient. It appears that high-dose immunoglobulin therapy and splenectomy should be considered earlier especially for a patient complicated with FG.

    Full Text Available Purpose: We report a case of unilateral exudative retinal detachment in a patient with thrombotic thrombocytopenic purpura (TTP, without associated hypertension, successfully treated with plasmapheresis. Case Report: A 46-year-old woman with a medical history of TTP presented with unilateral exudative retinal detachment. Biological and radiological assessment eliminated other causes of exudative retinal detachment, including hypertension. Plasma exchange was performed, followed by a rapid improvement in visual acuity and total disappearance of serous detachment. Conclusion: Exudative unilateral retinal detachment is a rare complication of TTP and can be successfully treated by plasma exchange.

    A 55-year-old woman suffered from hemorrhagic tendency. She had severe thrombocytopenia without any hematological or coagulatory abnormalities, and a bone marrow examination revealed an increased number of megakaryocytes without any abnormal cells or blasts. No lymphadenopathy or hepatosplenomegaly was observed on computed tomography. She was initially diagnosed with immune thrombocytopenic purpura (ITP). None of the treatments administered for ITP produced a response. However, abnormal cells were eventually found during the third bone marrow examination. The pathological diagnosis was mature B-cell lymphoma. Rituximab-containing chemotherapy produced a marked increase in the patient's platelet count, and her lymphoma went into complete remission.

    Thrombotic thrombocytopenic purpura (TTP) is a disseminated form of thrombotic microangiopathy with clinical findings consisting of fever, microangiopathic hemolytic anemia (MAHA), thrombocytopenia, fluctuating neurologic impairment and renal dysfunction. However, Microangiopathic hemolytic anemia has been described in association with disseminated malignancies, most commonly adenocarcinoma of the breast or stomach. We present three patients with microangiopathic anemia in whom metastatic cancer was finally diagnosed; however, they died of refractory hemolytic anemia in the end. The occurrence of microangiopathic hemolytic anemia and thrombocytopenia in patients with disseminated malignant in gastric adenocarsinoma is well documented. Therefore, the diagnosis of tumor-associated TTP should be considered in unresponsive TTP patient treated with plasmapheresis. (author)

    Full Text Available Topical Imiquimod is increasingly used in the treatment of lentigo maligna (LM for patients not suitable or willing for surgery. It acts as an immune response modifier and is recommended for use with caution in patients with autoimmune disorders. A review of the literature did not reveal any reported cases of Idiopathic Thrombocytopenic Purpura (ITP with the use of Imiquimod so far. We report a case of a 55-year-old woman with a history of Addison's and Graves' disease who had been diagnosed with lentigo maligna on the right nasal ala. Within two days of commencing of topical Imiquimod treatment, she was admitted to the hospital with extensive cutaneous and mucosal bruising and treated as acute Idiopathic Throbocytopenic Purpura. Deranged platelets were reversed promptly with treatment and Imiquimod discontinued. We demonstrate that Idiopathic Throbocytopenic Purpura is a potential life-threatening side effect of Imiquimod treatment and patients who have autoimmune disorders are at increased risk of developing this side effect. We recommend that Imiquimod is contraindicated in patients with autoimmune disease. Here we describe the clinical presentation and review the relevant literature on Imiquimod treatment for lentigo maligna and its potential side effects.

    Full Text Available Objectives: Splenectomy is performed in order to provide the treatment in the patients with severe idiopathic thrombocytopenic purpura, refractory to medical treatment. In this study, we aimed to investigate the postoperatif and longterm outcomes in the patients who underwent splenectomy with the diagnosis of idiopathic thrombocytopenic purpura.Materials and Methods: Between 2001-2010 at Dicle University Medical Faculty, General Surgery Department, a retrospective review of the 109 patients who had undergone splenectomy for ITP was reviewed. Age, gender, presence of accessory spleens and location, duration of the operation, number of preoperative platelet tranfusion, number of preoperative and postoperative blood transfusion, length of hospital stay, long-term outcomes, morbidity and mortality were recorded.Results: The mean age was 37.10 ± 16.62 (16-72, and there were 88 (80.7% female and 21 (19.3% male patients. The mean operation time was 44.87 ± 10:32 (30-120 minutes. The average postoperative blood and preoperative platelet transfusion were 1.63 ± 0.85 (0-3 and 2.01 ± 0.71 (1-3 units, respectively. The accessory spleens were encountered in 20 (18.3% patients at the ultrasonographic examination. And also the accessory spleens were encountered in 23 (21.1% patients during operation and confirmed with histopathologic examination. The most common localization of accessory spleens were splenic hilus. The postoperative complications were occurred in 16 patients (14.7% and the most complication was atelectasia. The mean length of hospital stay was 4:56 ± 2:45 (2-12 days. Patients were followed for an average of 28 (9-48 months. At the follow-up period, 1 (0.9 % patient had died.Conclusion: Splenectomy can be performed safely in the treatment of the patients with idiopathic thrombocytopenic purpura unresponsive to medical treatment. Long-term good results can be obtained with splenectomy in these patients. The accessory spleens should not be

    Advances in our understanding of the pathophysiology of both congenital and acquired thrombotic thrombocytopenic purpura (TTP) have led to both an increased understanding of the disease and novel approaches to therapy. The efficacy of rituximab in acquired TTP has led to consideration of rituximab as a prophylactic therapy to prevent relapse of TTP. Novel therapies that target the A1 domain of von Willebrand factor (VWF) to block the formation of microthrombotic disease have also entered clinical study and have demonstrated promise as potential therapeutic options. Additionally, a recombinant ADAMTS13 protease has been developed which may be an important therapeutic option for both congenital and acquired TTP. The development of these new therapeutic options for patients diagnosed with TTP has increased the importance of conducting prospective, randomized studies with these agents to both confirm their efficacy and more importantly understand their most appropriate role in the treatment of patients with TTP. © 2015 International Society on Thrombosis and Haemostasis.

    Thrombotic thrombocytopenic purpura (TTP) is a rare but potentially fatal condition. In women with a previous history of TTP there is increased risk of recurrence during pregnancy and the puerperium. There is some evidence that the risk of relapse during pregnancy is increased if the interval between the event and conception is short. We present a case in which pregnancy was achieved a few days after full recovery from an acute episode of severe acquired TTP (ADAMTS13 activity <0.1%) which was successfully treated with four courses of plasma exchange. There was no relapse of TTP during pregnancy and a healthy baby was delivered at term; the puerperium was uneventful. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2016-01-01

    Full Text Available Nocardia transvalensis complex includes a wide range of microorganisms with specific antimicrobial resistance patterns. N. transvalensis is an unusual Nocardia species. However, it must be differentiated due to its natural resistance to aminoglycosides while other Nocardia species are susceptible. The present report describes a Nocardia species involved in an uncommon clinical case of a patient with idiopathic thrombocytopenic purpura and pulmonary nocardiosis. Microbiological and molecular techniques based on the sequencing of the 16S rRNA gene allowed diagnosis of Nocardia transvalensis sensu stricto. The successful treatment was based on trimethoprim-sulfamethoxazole and other drugs. We conclude that molecular identification of Nocardia species is a valuable technique to guide good treatment and prognosis and recommend its use for daily bases diagnosis.

    Full Text Available Thrombotic thrombocytopenic purpura (TTP is a serious disorder with a significant morbidity and mortality. Majority of cases of TTP are idiopathic, but some cases may be secon-dary to connective tissue diseases. TTP has been rarely associated with systemic lupus erythe-matosus (SLE and may be refractory to treatment with plasma exchange, requiring immuno-suppressive therapy. We describe a patient with TTP and SLE who was refractory to plasma exchange and corticosteroids but responded to anti-CD20 antibody rituximab with continued re-mission after eight months of follow-up. Rituximab appears to be an effective treatment in re-fractory cases of TTP associated with SLE.

    2015-12-01

    Full Text Available Peliosis hepatis is a rare condition that can cause hepatic hemorrhage, rupture, and ultimately liver failure. Several authors have reported that peliosis hepatis develops in association with chronic wasting disease or prolonged use of anabolic steroids or oral contraceptives. In this report we describe a case in which discontinuation of steroid therapy improved the condition of a patient with peliosis hepatis. Our patient was a 64-year-old woman with a history of long-term steroid treatment for idiopathic thrombocytopenic purpura . Her symptoms included abdominal pain and weight loss; the only finding of a physical examination was hepatomegaly. We performed computed tomography (CT and magnetic resonance imaging (MRI of the liver and a liver biopsy. Based on these findings plus clinical observations, she was diagnosed with peliosis hepatis and her steroid treatment was terminated. The patient recovered completely 3 months after steroid discontinuation, and remained stable over the following 6 months.

    Although thrombocytopenia is known to be associated with pathogenesis of retinopathy of prematurity (ROP), immune thrombocytopenic purpura (ITP) is rare in infancy and not reported to occur with ROP. A preterm infant with aggressive posterior ROP developed bilateral massive subconjunctival haemorrhage after scleral indentation during screening. On evaluation, the infant was found to have severe ITP. Following intravenous transfusion of platelets and immunoglobulin, platelet counts improved and subconjunctival haemorrhage resolved over time. This case highlights the unusual presentation of ITP and also discusses the association of thrombocytopenia with ROP. Ophthalmologists should get prompt haematological work-up of such occurrences. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

    Full Text Available Although both leukopenia and thrombocytopenia are not uncommon hematological findings among patients with novel 2009 H1N1 influenza virus infection, immune thrombocytopenic purpura has rarely been shown to be associated with this novel influenza A infection. Here, we describe a previously healthy adolescent who presented with fever, influenza-like symptoms and acute onset of generalized petechiae and active oral mucosa bleeding on the third day of his illness. Severe leukopenia and thrombocytopenia were found. There was neither malignancy nor blast cells found by bone marrow aspiration. Real-time reverse transcriptase polymerase chain reaction was positive for novel 2009 H1N1 influenza infection. Novel influenza-associated atypical immune thrombocytopenic purpura was diagnosed. The patient recovered uneventfully after oseltamivir and methylprednisolone therapy.

    Acute myocardial infarction is a common complication of thrombotic thrombocytopenic purpura (TTP), but rarely the presenting manifestation. Anti-thrombotic therapy for myocardial infarction is rarely utilized in the setting of TTP because of elevated bleeding risk. We report a case of TTP presenting with ST-segment elevation myocardial infarction and treated with thrombolytic therapy. The resultant cardiac and neurological complications highlight the challenges of using evidence-based therapy for myocardial infarction in the setting of TTP.

  15. Platelet destruction in autoimmune thrombocytopenic purpura: kinetics and clearance of indium-111-labeled autologous platelets

    1989-01-01

    Using autologous 111 In-labeled platelets, platelet kinetics and the sites of platelet destruction were assessed in 16 normal subjects (13 with and three without spleens), in 17 studies of patients with primary autoimmune thrombocytopenic purpura (AITP), in six studies of patients with secondary AITP, in ten studies of patients with AITP following splenectomy, and in five thrombocytopenic patients with myelodysplastic syndromes. In normal subjects, the spleen accounted for 24 +/- 4% of platelet destruction and the liver for 15 +/- 2%. Untreated patients with primary AITP had increased splenic destruction (40 +/- 14%, p less than 0.001) but not hepatic destruction (13 +/- 5%). Compared with untreated patients, prednisone treated patients did not have significantly different spleen and liver platelet sequestration. Patients with secondary AITP had similar platelet counts, platelet survivals, and increases in splenic destruction of platelets as did patients with primary AITP. In contrast, patients with myelodysplastic syndromes had a normal pattern of platelet destruction. In AITP patients following splenectomy, the five nonresponders all had a marked increase (greater than 45%) in liver destruction compared to five responders (all less than 40%). Among all patients with primary or secondary AITP, there was an inverse relationship between the percent of platelets destroyed in the liver plus spleen and both the platelet count (r = 0.75, p less than 0.001) and the platelet survival (r = 0.86, p less than 0.001). In a stepwise multiple linear regression analysis, total liver plus spleen platelet destruction, the platelet survival and the platelet turnover were all significant independent predictors of the platelet count. Thus platelet destruction is shifted to the spleen in primary and secondary AITP. Failure of splenectomy is associated with a marked elevation in liver destruction

    The clinical course and response to therapy of patients with immune thrombocytopenic purpura (ITP) are not completely determined by the level of IgG present on the platelet surface. It is possible that antibodies of other immunoglobulin classes also play a role in platelet destruction in some of these patients. Therefore, the authors studied 175 patients with ITP for the presence of IgM anti-platelet antibodies using radiolabeled polyclonal or monoclonal anti-IgM. They observed that 57% of patients with clinical ITP had increased levels of IgM on their platelets, compared with normal controls and patients with thrombocytopenia who did not have ITP. They obtained similar results using either radiolabeled polyclonal or monoclonal anti-IgM, reagents whose integrity was first characterized using erythrocytes coated with defined amounts of IgM antibody. Among patients with increased platelet-IgM there was a significant correlation both with the presence of increased platelet-C3 as well as the amount of platelet-C3. The authors demonstrated the presence of warm-reacting IgM anti-platelet antibodies in the plasma of two of these patients who were further studied. These studies demonstrate the presence of warm-reacting IgM anti-platelet antibodies in some patients with ITP. They suggest that the binding of complement to platelets by IgM antibodies may initiate platelet clearance as well as enhance the effect of IgG antibodies in ITP

    The long-term outcomes of laparoscopic splenectomy (LS) versus open splenectomy (OS) in patients with idiopathic thrombocytopenic purpura (ITP) are not known. A retrospective analysis of 73 patients who underwent splenectomy (32 LS and 41 OS) for refractory ITP between April 2003 and June 2012 was conducted. LS was associated with shorter hospital stay (P = 0.01), less blood loss and blood transfusion during surgery, quicker resumption of oral diet (P < 0.0001), and earlier drain removal (P < 0.01). Conversion to OS was required in 4 patients (12.5%). Operation time was significantly longer in LS (P < 0.0001). Deep venous thrombosis (DVT) was observed in 1 patient after LS and in 4 patients after OS (P = 0.52). One patient died from intraperitoneal bleeding after OS, another patient developed pulmonary embolism. Median follow-up of 36 months was performed in LS group (29 of 32, 91%) and of 46 months in OS group (35 of 41, 85%), 25 patients (86%) in LS group and 32 (91%) in OS group reached sustained complete response (P = 0.792). Kaplan-Meier analysis showed that there was no significant difference in the relapse-free survival rate between the groups (P = 0.777). In conclusion, the long-term outcome of laparoscopic splenectomy is not different from that of open splenectomy for patients with ITP. PMID:24833154

    Patients who have recovered from their acute episode of acquired ADAMTS13-deficient thrombotic thrombocytopenic purpura (TTP) were once thought to have complete recovery except for risk of relapse. Data from previous publications from the Oklahoma TTP-hemolytic uremic syndrome (HUS) Registry are summarized. Patients have decreased cognitive function and increased prevalence of hypertension, systemic lupus erythematosus, major depression, and albuminuria as compared to the expected values from the US population. The proportion of patients that died during the follow-up period was greater than expected based on the US population reference population. Among women who had a pregnancy following recovery from TTP, relapse during pregnancy or postpartum is uncommon, but the occurrence of preeclampsia may be increased. Thirteen of 16 pregnancies in these women resulted in healthy children. Increased morbidity and mortality in TTP patients following recovery suggest that TTP may be more of a chronic disorder than a disorder with acute episodes and complete recovery. © 2015 International Society on Thrombosis and Haemostasis.

    We have studied 8 normal subjects, and 12 patients with idiopathic thrombocytopenic purpura whose platelet counts ranged from 9x10 9 /L to 40x10 9 /L. Autologous platelets labeled with 111 In-tropolone were used for evaluation of mean platelet survival, platelet turnover, platelet sequestration sites, and platelet production (turnover) to clearance (sum of platelet uptake in the liver and the spleen) ratio. Platelet survival correlated directly with platelet counts. There was no significant correlation between the platelet sequestration pattern and platelet count, survival, or turnover. Sum of platelet uptake in the liver and the spleen showed a significant inverse correlation with platelet survival. No significant correlation was found between platelet turnover and platelet count. There was a significant correlation between the platelet production and clearance index when all subjects were analyzed. The distribution of platelet turnover showed considerable individual variation; eight of twelve patients showed platelet turnover less than mean minus 2SD of the control value, but others showed normal range. We conclude that although platelet destruction mechanism in RES shows a primary role of thrombocytopenia, impaired rate of effective thrombopoiesis may also contribute to disease severity in ITP.

    Splenic dynamics of 111 In-labeled platelets and platelet-associated IgG in 33 patients with idiopathic thrombocytopenic purpura (ITP) were studied. Two half-lives were calculated for the biexponential splenic time-activity curve after i.v. injection of 111 In-labeled platelets. There was no difference in the mean half-life of the rapid component of the splenic curve (ST1) when patients with negative or slightly positive platelet suspension immunofluorescence test (PSIFT) were compared to those with strongly positive PSIFT (3.0 ± 0.7 min vs. 3.6 ± 0.4, p greater than 0.05). Mean half-life of the slow component of the splenic curve (ST2) was found to be longer in patients with a strongly positive than a negative or weakly positive PSIFT (26 ± 5 min vs. 13.2 ± 1.0 min, p less than 0.01). It seems that determination of the two components of the splenic time-activity curve provides a useful method for studying platelet kinetics in ITP

    2016-04-01

    Full Text Available Selective splenic artery embolization (SSAE is a nonsurgical intervention characterized by the transcatheter occlusion of the splenic artery and/or its branch vessels using metallic coils or other embolic devices. It has been applied for the management of splenic trauma, hypersplenism with portal hypertension, hereditary spherocytosis, thalassemia and splenic hemangioma. We hereby describe a case of a patient affected by idiopathic thrombocytopenic purpura (ITP and warm auto-immune hemolytic anemia (AIHA both resistant to immunosuppressive and biological therapies, not eligible for a surgical intervention because of her critical conditions. She underwent SSAE and achieved a hematologic complete response within a few days without complications. SSAE is a minimally invasive procedure to date not considered a standard option in the management of AIHA and ITP. However, following the progressive improvement of the techniques, its indications have been extended, with a reduction in morbidity and mortality compared to splenectomy in patients with critical clinical conditions. SSAE was a lifesaving therapeutic approach for our patient and it may represent a real alternative for the treatment of resistant AIHA and ITP patients not eligible for splenectomy.

This was a retrospective analysis of ITP patients who failed medical therapy and were treated with OS between 1997 and 2014 at the Jinshan Hospital, China. Follow-up was 60 months. Surgical effect was determined from platelet counts and bleeding episodes. Complications were assessed including bleeding episodes. Preoperative factors were identified by logistic regression analysis. Fifty-six patients (48.2 ± 16.2 yr old; 39 females) were included. Disease course was 31.2 ± 48.2 months; 91.1% patients had preoperative platelet count effect at 1 wk, 1 month, 1 yr, and 5 yrs was in 91.1%, 92.9%, 91.1%, and 89.3% patients, respectively. Pneumonia or lower extremity thrombosis occurred in 7.1% patients. Postoperative mild, moderate, and severe bleeding occurred in 33.9%, 50.0%, and 16.1% patients, respectively. No patients required blood transfusion. Mortality was zero. Larger spleen size associated with surgical effect at 1 wk, 1 month, and 1 yr, and lower preoperative minimum platelet count associated with effect at 5 yrs (P effective treatment with less complications for the management of ITP.

    Full Text Available Idiopathic thrombocytopenic purpura (ITP is an acute self-limited bleeding disorder that can progress to chronic form in 10-15% of the cases. Helicobacter pylori (H. pylori infection is a possible cause of chronic ITP. We studied 30 children with resistant chronic ITP for H. pylori infection based on the detection of H. pylori fecal antigen. This retrospective study was based on data obtained from medical records of 30 children aged between five and 17 years (median age at ITP diagnosis was ten years. A specially-designed data sheet was used to record information on age, sex, duration of disease, family history of bleeding disorders, previous treatments and median platelet count. In patients with H. pylori infection, antimicrobial treatment consisted of amoxicillin, metronidazol and omeprazol. Response was assessed every month for one year and defined as complete (platelet count >150x109/L or partial (platelet count between 50 and 150x109/L. We detected H. pylori infection in 5 patients. In 4 of them increased platelet count was seen during one year of follow-up and in one patient the platelet count was acceptable during six months. Although the pathological mechanism of H. pylori-induced thrombocytopenia was unclear in our patient sample, the assessment of H. pylori infection and use of eradication therapy should be attempted in chronic and resistant ITP patients.

    The congenital form of thrombotic thrombocytopenic purpura (Upshaw-Schulman syndrom) is a result of genetically conditioned dysfunction of protease ADAMTS 13 enzyme which is responsible for von Wiellebrand factor multimer disintegration. The disease is inherited autosomally and recessively. The decrease of ADAMTS 13 activity results in intravascular clotting process activation with rapid lowering of platelet count, haemolytic anaemia, and occurence of schistocytes. Clinically, the disease is characterized by a range of symptoms such as severe jaundice in neonatal period, embolicthrombotic incidents of nervous system and progressive dysfunction of kidneys and other organs. Delaying diagnosis and hence administering of freshly frozen plasma leads to death. Molecular diagnosis allows for identification of genetical profile of the patient, and showing lowered enzyme activity is a basis for regular prophylactic plasma administration which is the protease donor. In our study we present members of a Polish family identified with ADAMTS 13 mutation. 52 old male with heterozygotic mutation of exon 29 (4143_4144insA) and in exon 19 (c2281G>A; Gly761Ser), experienced a few episodes of ischaemic stroke with ongoing neurological deficiency and developed chronic kidney disease. His 16-year old daughter with double homozygotic mutation in exon 29 (4143_4144insA) after severe episode of TTP at the age of 4 has been receiving plasma every 2 weeks for 12 years, which prevented her from other disorders. Target treatment introduced to clinical practice by means of ADAMTS 13 obtained by genetic recombination technology raises hopes.

    Acquired thrombotic thrombocytopenic purpura (TTP) is caused by autoantibodies against ADAMTS13. TTP patients run a rapidly fatal course unless immediate plasma exchange (PEX) is initiated upon diagnosis. Herein, we report a 72-year-old man with TTP, which developed after he underwent artificial blood vessel replacement surgery for an abdominal aneurysm with impending rupture. In the perioperative period, the patient received several platelet transfusions for severe thrombocytopenia (minimum platelet count: 0.6×10(4)/μl). Thereafter, he was admitted to our department for rapidly progressing coma with multiple cerebral infarctions, and was transferred to the ICU. Based on the tentative diagnosis of TTP, we immediately began PEX and steroid pulse therapy. The diagnosis was confirmed thereafter by markedly reduced ADAMTS13 activity (<0.5%) and his being positive for the ADAMTS13 inhibitor. We performed PEX for five consecutive days and administered high-dose prednisolone (PSL). On the second hospital day (HD), his platelet count rose along with improvement of his consciousness level. The ADAMTS13 inhibitor was not detected on the 10th HD. TTP did not relapse and his general condition improved despite tapering of PSL. In this case, by closely monitoring ADAMTS13-related parameters and minimizing the number of plasma exchanges, the patient was able to achieve a remission without the use of boosting inhibitors.

    Full Text Available Thrombotic thrombocytopenic purpura (TTP is a multisystemic disorder characterized by microangiopathic hemolytic anemia and thrombocytopenia, which may be accompanied by fever, renal, or neurologic abnormalities. Cases are divided into acute idiopathic TTP and secondary TTP. Autoimmune diseases, especially systemic lupus erythematosus, in association with TTP have been described so far in many patients. In contrast, TTP occurring in a patient with mixed connected tissue disease (MCTD is extremely rare and has only been described in nine patients. We describe the case of a 42-year-old female with MCTD who developed thrombocytopenia, microangiopathic hemolytic anemia, fever, and neurological symptoms. The patient had a good clinical evolution with infusion of high volume of fresh frozen plasma, steroid therapy, and support in an intensive care unit. Although the occurrence of TTP is rare in MCTD patients, it is important to recognize TTP as a cause of thrombocytopenia and hemolytic anemia in any patient with autoimmune diseases. Prompt institution of treatment remains the cornerstone of treatment of TTP even if plasma exchange is not available like what frequently happens in developing countries.

    Full Text Available Black people are at increased risk of thrombotic thrombocytopenic purpura (TTP. Whether clinical presentation of TTP in Black patients has specific features is unknown. We assessed here differences in TTP presentation and outcome between Black and White patients. Clinical presentation was comparable between both ethnic groups. However, prognosis differed with a lower death rate in Black patients than in White patients (2.7% versus 11.6%, respectively, P = .04. Ethnicity, increasing age and neurologic involvement were retained as risk factors for death in a multivariable model (P < .05 all. Sixty-day overall survival estimated by the Kaplan-Meier curves and compared with the Log-Rank test confirmed that Black patients had a better survival than White patients (P = .03. Salvage therapies were similarly performed between both groups, suggesting that disease severity was comparable. The comparison of HLA-DRB1*11, -DRB1*04 and -DQB1*03 allele frequencies between Black patients and healthy Black individuals revealed no significant difference. However, the protective allele against TTP, HLA-DRB1*04, was dramatically decreased in Black individuals in comparison with White individuals. Black people with TTP may have a better survival than White patients despite a comparable disease severity. A low natural frequency of HLA-DRB1*04 in Black ethnicity may account for the greater risk of TTP in this population.

    Splenectomy is the definitive second-line therapy for refractory immune thrombocytopenic purpura (ITP), and has a reported response rate of 50-80%. Medical attention should be reconsidered when there is no evidence of accessory spleen in refractory ITP patients after splenectomy. The purpose of this study was to determine whether platelet count evolution differs between patients with a successful or unsuccessful result after splenectomy for ITP. Archived records of 104 consecutive patients that underwent splenectomy for ITP were reviewed. Patients were divided into two groups (failures and successes) using a final follow-up platelet count of 100,000/μL as a cut-off. Platelet count evolutions in these two groups were compared using the Student's t test. Successes and failures were found to have significantly different platelet counts from two days postoperatively (P = 0.016). The area under the receiver operating characteristic curve was 0.630 (95% confidence interval, 0.518-0.741, P = 0.030), and when a cut-off value of 100,000/μL was used, sensitivity and specificity were 68.2 and 51.2%, respectively. To obtain positive and negative predictive values exceeding 50%, additional platelet counts were required at one week and one month after splenectomy. We propose a protocol for ITP follow-up after splenectomy.

    Full Text Available Introduction: Thrombotic thrombocytopenic purpura (TTP is a thrombotic microangiopathy caused by congenital or inherited disorders involving the processing of the ultra-large forms of von Willebrand factor. As a result, platelet-rich microthrombi form in the small arterial vessels of various organs, particularly those of the brain, heart, and kidneys. The idiopathic autoimmune form of TTP is the most common. There are various subgroups of acquired TTP associated with HIV infection, sepsis, pregnancy, autoimmune disease, various disseminated malignancies, and drugs. If not promptly treated, TTP is associated with high mortality, making it a true medical emergency. Materials and methods: The article is based on a review of the literature published between January and October of 2009. Its aim is to clarify the diagnosis, treatment, and follow-up of TTP. Results: Diagnostic criteria include the presence of microangiopathic hemolytic anemia associated with thrombocytopenia in the absence of other obvious causes. Assays of ADAMTS13 activity and titration of acquired antibodies against this enzyme are indicated in the follow-up of disease and as prognostic indicators. Treatment centers around daily plasma exchange associated with immunosuppressant drug therapy, particularly steroids and more recently the monoclonal anti-CD20 antibody rituximab. Discussion: Despite improved treatment, TTP is still associated with significant mortality (10—20%, particularly when plasma exchange is initiated late. Relapse also occurs in a substantial proportion of patients (10—40% although the frequency of this outcome may be reduced by rituximab therapy.

    Idiopathic thrombocytopenic purpura (ITP) is typically a diagnosis of exclusion, assigned by clinicians after ruling out other identifiable etiologies. Since a report by Gasbarrini et al. in 1998, an accumulating body of evidence has proposed a pathophysiological link between ITP and chronic Helicobacter pylori (H. pylori) infection. Clinical reports have described a spontaneous resolution of ITP symptoms in about 50% of chronic ITP patients following empirical treatment of H. pylori infection, but response appears to be geography dependent. Studies have also documented that ITP patients in East Asian countries are more likely to express positive antibody titers against H. pylori-specific cytotoxic-associated gene A (CagA), a virulence factor that is associated with an increased risk for gastric diseases including carcinoma. While a definitive mechanism by which H. pylori may induce thrombocytopenia remains elusive, proposed pathways include molecular mimicry of CagA by host autoantibodies against platelet surface glycoproteins, as well as perturbations in the phagocytic activity of monocytes. Traditional treatments of ITP have been largely empirical, involving the use of immunosuppressive agents and immunoglobulin therapy. However, based on the findings of clinical reports emerging over the past 20 years, health organizations around the world increasingly suggest the detection and eradication of H. pylori as a treatment for ITP. Elucidating the exact molecular mechanisms of platelet activation in H. pylori-positive ITP patients, while considering biogeographical differences in response rates, could offer insight into how best to use clinical H. pylori eradication to treat ITP, but will require well-designed studies to confirm the suggested causative relationship between bacterial infection and an autoimmune disease state.

    Primary immune thrombocytopenic purpura (ITP), caused by immune system dysfunction, is recognized as the leading cause of thrombocytopenia in pediatric population. Nonetheless, inadequate studies have been performed on bone marrow immunophenotyping of children with ITP. In this study, we aimed to investigate the immunophenotype of bone marrow lymphocytes in these children. Between 2008 and 2012, 35 children with ITP and 26 age and sex matched healthy controls were recruited. All participants underwent bone marrow aspiration. Appropriate B-cell, T-cell, and myeloid lineage monoclonal antibodies were employed to determine the immunophenotype of these patients. CD10, CD19, and CD20, all indicative of premature B-cell markers, were significantly greater in children with ITP. CD22, mainly expressed on mature B cells was slightly, but not significantly reduced in the patients' group (P = .42). On the other hand, T cell markers including CD2, CD3, CD5, and CD7 were underexpressed. CD33, a specific marker for myeloid lineage, was underexpressed in the patients' group (5.6 ± 4.7 vs. 12.9 ± 7.3, P < .001). Noteworthy, the immunophenotype did not significantly differ between acute and persistent cases. Overall, a phenotype characterized by increased pre-B-cell markers along with decreased T cell immunophenotypic markers was observed in bone marrow lymphocytes of children with ITP in the present study. Further larger scale studies are recommended to confirm our findings, as precise mapping of the immunophenotype of lymphocytes in these patients would pave the road to improved diagnosis and treatment.

    Immune thrombocytopenic purpura (ITP) results from accelerated platelet destruction mediated by autoantibodies to platelet glycoproteins. Some patients with chronic ITP are refractory to all therapies [steroids, intravenous immunoglobulin (IVIG), anti-D and immunosuppresive drugs] and have chronic low platelet counts and episodic bleeding. We retrospectively evaluated the efficacy and safety of rituximab treatment and splenectomy in paediatric patients diagnosed with chronic and refractory ITP who were unresponsive to steroids, IVIG, cyclosporine and mycophenolate mofetil. Records of patients with chronic and refractory ITP in 459 patients with primary ITP who were followed up in our hospital from January 2005 to December 2014 were reviewed. Fifteen of patients received rituximab and/or applied splenectomy. Fifteen chronic ITP patients (10 boys, five girls) with a mean age of 10 years were enrolled in the study. Two of these patients were suffering from Evans syndrome. The median time since diagnosis of ITP was 10 years. The median follow-up duration after starting Rituximab and splenectomy were 13 and 9.5 months, respectively.None of the seven patients who were treated with rituximab achieved a response. A splenectomy was performed in six of the seven patients who had been treated with rituximab. Complete and partial responses were achieved in 67 and 33% of the patients, respectively. We evaluated the clinical characteristics and responses of chronic ITP patients who did not receive rituximab therapy and underwent a splenectomy. The success rate was 100% in the eight patients with chronic and refractory ITP. Rituximab therapy might not be beneficial for some children with severe chronic ITP who are refractory to standard agents. A splenectomy might be useful and preferable to rituximab.

    Essentials ADAMTS-13-deficiency is a cause of thrombotic thrombocytopenic purpura (TTP). Preclinical safety of recombinant human ADAMTS-13 (BAX930) was shown in animal models. Preclinical efficacy of BAX930 was shown in a mouse model of TTP. BAX930 showed advantageous efficacy over fresh frozen plasma, the current standard of care. Click to hear Dr Cataland and Prof. Lämmle present a seminar on Thrombotic Thrombocytopenic Purpura (TTP): new Insights in Pathogenesis and Treatment Modalities. Background Thrombotic thrombocytopenic purpura (TTP) is a rare blood disorder characterized by microthrombosis in small blood vessels of the body, resulting in a low platelet count. Baxalta has developed a new recombinant ADAMTS-13 (rADAMTS-13) product (BAX930) for on-demand and prophylactic treatment of patients with hereditary TTP (hTTP). Objectives To evaluate the pharmacokinetics, efficacy and safety of BAX930 in different species, by use of an extensive preclinical program. Methods The prophylactic and therapeutic efficacies of BAX930 were tested in a previously established TTP mouse model. Pharmacokinetics were evaluated after single intravenous bolus injection in mice and rats, and after repeated dosing in cynomolgus monkeys. Toxicity was assessed in rats and monkeys, safety pharmacology in monkeys, and local tolerance in rabbits. Results BAX930 was shown to be efficacious, as demonstrated by a stabilized platelet count in ADAMTS-13 knockout mice that were thrombocytopenic when treated. Prophylactic efficacy was dose-dependent and comparable with that achieved by treatment with fresh frozen plasma, the mainstay of hTTP treatment. Therapeutic efficacy was treatment interval-dependent. Safety pharmacology evaluation did not show any deleterious effects of BAX930 on cardiovascular and respiratory functions in monkeys. The compound's pharmacokinetics were similar and dose-proportional in mice, rats, and monkeys. BAX930 was well tolerated in rats, monkeys, and rabbits, even

    Essentials Acquired thrombotic thrombocytopenic purpura (aTTP) is linked with significant morbidity/mortality. Caplacizumab's effect on major thromboembolic (TE) events, exacerbations and death was studied. Fewer caplacizumab-treated patients had a major TE event, an exacerbation, or died versus placebo. Caplacizumab has the potential to reduce the acute morbidity and mortality associated with aTTP. Background Acquired thrombotic thrombocytopenic purpura (aTTP) is a life-threatening autoimmune thrombotic microangiopathy. In spite of treatment with plasma exchange and immunosuppression, patients remain at risk for thrombotic complications, exacerbations, and death. In the phase II TITAN study, treatment with caplacizumab, an anti-von Willebrand factor Nanobody ® was shown to reduce the time to confirmed platelet count normalization and exacerbations during treatment. Objective The clinical benefit of caplacizumab was further investigated in a post hoc analysis of the incidence of major thromboembolic events and exacerbations during the study drug treatment period and thrombotic thrombocytopenic purpura-related death during the study. Methods The Standardized Medical Dictionary for Regulatory Activities (MedDRA) Query (SMQ) for 'embolic and thrombotic events' was run to investigate the occurrence of major thromboembolic events and exacerbations in the safety population of the TITAN study, which consisted of 72 patients, of whom 35 received caplacizumab and 37 received placebo. Results Four events (one pulmonary embolism and three aTTP exacerbations) were reported in four patients in the caplacizumab group, and 20 such events were reported in 14 patients in the placebo group (two acute myocardial infarctions, one ischemic stroke, one hemorrhagic stroke, one pulmonary embolism, one deep vein thrombosis, one venous thrombosis, and 13 aTTP exacerbations). Two of the placebo-treated patients died from aTTP during the study. Conclusion In total, 11.4% of caplacizumab

    Essentials Genetic predisposition to acquired thrombotic thrombocytopenic purpura (aTTP) is mainly unknown. Genetic risk factors for aTTP were studied by Immunochip analysis and replication study. Human leukocyte antigen (HLA) variant rs6903608 conferred a 2.5-fold higher risk of developing aTTP. rs6903608 and HLA-DQB1*05:03 may explain most of the HLA association signal in aTTP. Click to hear Dr Cataland's presentation on acquired thrombotic thrombocytopenic purpura SUMMARY: Background Acquired thrombotic thrombocytopenic purpura (TTP) is a rare, life-threatening thrombotic microangiopathy associated with the development of autoantibodies against the von Willebrand factor-cleaving protease ADAMTS-13. Similarly to what has been found for other autoimmune disorders, there is evidence of a genetic contribution, including the association of the human leukocyte antigen (HLA) class II complex with disease risk. Objective To identify novel genetic risk factors in acquired TTP. Patients/Methods We undertook a case-control genetic association study in 190 European-origin TTP patients and 1255 Italian healthy controls by using the Illumina Immunochip. Replication analysis in 88 Italian cases and 456 controls was performed with single-nucleotide polymorphism (SNP) TaqMan assays. Results and conclusion We identified one common variant (rs6903608) located within the HLA class II locus that was independently associated with acquired TTP at genome-wide significance and conferred a 2.6-fold increased risk of developing a TTP episode (95% confidence interval [CI] 2.02-3.27, P = 1.64 × 10 -14 ). We also found five non-HLA variants mapping to chromosomes 2, 6, 8 and X that were suggestively associated with the disease: rs9490550, rs115265285, rs5927472, rs7823314, and rs1334768 (nominal P-values ranging from 1.59 × 10 -5 to 7.60 × 10 -5 ). Replication analysis confirmed the association of HLA variant rs6903608 with acquired TTP (pooled P = 3.95 × 10 -19 ). Imputation of classic

    Full Text Available Thrombotic thrombocytopenic purpura (TTP is a thrombotic microangiopathy characterized by endothelial cell damage, resulting in microangiopathic hemolytic anemia, thrombocytopenia, and various degrees of neurological and renal impairment caused by microvascular thrombi. It is rare in children and frequently follows a fatal course. TTP is divided into 2 types: one is inherited and associated with ADAMTS-13 gene mutations and the other is acquired and associated with anti-ADAMTS-13 autoantibodies. The measurement of ADAMTS-13 activity in plasma, identification of ADAMTS-13 circulating inhibitor, anti-ADAMTS-13 IgG, and ADAMTS-13 gene sequencing are crucial to the diagnosis of TTP. Plasma exchanges are the first-line treatment for acquired TTP, combined with steroids and immunosuppressive drugs. Here, we describe the case of an adolescent patient with TTP, confirmed by decreased level of ADAMTS-13 activity and an increased level of ADAMTS-13 inhibitor, who was successfully treated by plasma exchanges.

    Plasmapheresis (PP) is widely known as the standard therapy for thrombotic thrombocytopenic purpura (TTP). Citrate is used as an anticoagulant in fresh frozen plasma, and the large amount of citrate infused during PP induces metabolic alkalosis. A 29-year-old woman was diagnosed with TTP associated with systemic lupus erythematosus, and was treated by daily PP in addition to a steroid, an immunosuppressant, vincristine, and cyclophosphamide. Uncompensated alkalosis caused by a combination of metabolic and respiratory alkalosis developed after artificial ventilation was discontinued. Her metabolic status improved after controlling her respiratory status and the activity of the TTP. Metabolic alkalosis is a common complication in TTP patients treated by frequent PP, but several factors that affect metabolic status may aggravate the alkalosis and induce uncompensated alkalosis.

    Objective: To observe the long-term efficacy of partial spleen embolization combined with vincristine infusion in treating refractory idiopathic thrombocytopenic purpura (ITP) and Evans syndrome. Methods: During the period of 2000-2007, partial spleen embolization together with vincristine infusion was carried out in 30 patients with refractory idiopathic thrombocytopenic purpura (n=24) or Evans syndrome (n=6). Vincristine infusion (2 mg) via splenic artery was performed before partial spleen embolization procedure. The long-term effectiveness was observed and analyzed. Results: One week after the treatment, the platelet count was increased from preoperative (10.23±8.28) × 10 9 /L to (140.28±85.45) × 10 9 /L in patients with ITP, while the platelet count was increased from preoperative (12±8) × 10 9 /L to (210±60) × 10 9 /L in patients with Evans syndrome. Meanwhile, the hemoglobin level showed an increase in different degrees, from preoperative (63.00±13.62) g/L to postoperative (123.00±13.14) g/L. The therapeutic effectiveness was 100%. During the follow-up time lasting for 3-5 years, recurrence was seen in 11 patients (36.7%) and the overall efficacy rate was 63.3%. Conclusion: For the treatment of refractory idiopathic thrombocytopenic purpura and Evans syndrome, partial spleen embolization combined with vincristine infusion carries reliable long-term efficacy.

    Full Text Available Abstract Introduction Thrombotic thrombocytopenic purpura-hemolytic uremic syndrome is a life-threatening condition with various etiopathogeneses. Without therapy approximately 90% of all patients die from the disease. Case presentation We report the case of a 17-year-old Caucasian woman with widespread hematomas and headache. Due to hemolytic anemia, thrombocytopenia, and schistocytosis, thrombotic thrombocytopenic purpura-hemolytic uremic syndrome was suspected and plasma exchange therapy was initiated immediately. Since her thrombocyte level did not increase during the first week of therapy, plasma treatment had to be intensified to a twice-daily schedule. Further diagnostics showed markedly reduced activities of both ADAMTS-13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 - also known as von Willebrand factor-cleaving protease and factor H. Test results for antibodies against both proteins were positive. While plasma exchange therapy was continued, rituximab was given once weekly for four consecutive weeks. After the last dose, thrombocytes and activities of ADAMTS-13 and factor H increased into the normal range. Our patient improved and was discharged from the hospital. Conclusions Since no clinical symptoms/laboratory findings indicated a malignant or specific autoimmune-mediated disorder, the diagnosis made was thrombotic thrombocytopenic purpura-hemolytic uremic syndrome due to idiopathic combined, autoantibody-mediated ADAMTS-13/factor H deficiency.

    Thrombotic thrombocytopenic purpura is a thrombotic microangiopathy related to a severe deficiency of ADAMTS13 (a disintegrin and metalloprotease with thrombospondin type 1 repeats, member 13; activity purpura at initial presentation. Between Jan 1, 1999, and Dec 31, 2013, we did a cross-sectional analysis of the French national registry for thrombotic microangiopathy to identify all patients with adult-onset thrombotic microangiopathy (first episode after age 18 years) who had severe ADAMTS13 deficiency at presentation. ADAMTS13 activity, anti-ADAMTS13 IgG, and ADAMTS13 gene mutations were investigated by a central laboratory. We collected patients' clinical data for correlation with their ADAMTS13 phenotype and genotype. We used logistic regression analysis to identify variables significantly associated with idiopathic thrombotic thrombocytopenic purpura, as measured by estimated odds ratios (ORs) and 95% CIs. This study is registered with ClinicalTrials.gov, number NCT00426686. We enrolled 939 patients with adult-onset thrombotic thrombocytopenic purpura, of whom 772 (82%) patients had available data and samples at presentation and comprised the cohort of interest. The prevalence of thrombotic thrombocytopenic purpura in France was 13 cases per million people. At presentation, 378 (49%) patients had idiopathic thrombotic thrombocytopenic purpura, whereas 394 (51%) patients had disease associated with miscellaneous clinical situations (infections, autoimmunity, pregnancy, cancer, organ transplantation, and drugs). Pathophysiologically, three distinct forms of thrombotic thrombocytopenic purpura were observed: 585 (75%) patients had autoimmune disease with anti-ADAMTS13 IgG, 166 (22%) patients had acquired disease of unknown cause and 21 (3%) patients had inherited disease (Upshaw-Schulman syndrome) with mutations of the ADAMTS13 gene. Idiopathic thrombotic thrombocytopenic purpura were mainly autoimmune (345 [91%] cases), whereas non-idiopathic diseases were

    In pregnancy, it may be difficult to differentiate the syndrome of hemolysis, elevated liver enzymes, and low platelets from thrombotic thrombocytopenia purpura. Severely depressed (present a case of a patient that presented at 20 weeks gestation with elevated liver enzymes and thrombocytopenia. The diagnosis was unclear at the time of presentation. She underwent induction of labor, and during the postpartum course, she was eventually diagnosed with thrombotic thrombocytopenia purpura; however, her activity level of a disintegrin and metalloproteinase with thrombospondin motifs-13 was only moderately depressed at 15% (normal pregnancy value 41%-105%).

    Platelet kinetics in patients with idiopathic thrombocytopenic purpura (ITP) was investigated by applying various models (compartmental and open models, and functional and uptake analyses) to data on indium-111 labelled platelets monitored with a gamma camera following intravenous injection of labelled platelets. The usefulness of the selected models was tested by relating kinetic data to pathophysiological phenomena. A comparison of the results of platelet and colloid kinetics showed that the splenic platelet kinetics in ITP patients does not seem to be primarily dependent on the reticuloendothelial system. Although closed three-compartmental analysis seemed to be superior to the other models applied, none of the methods of analysis tested in this study appears to provide a complete description of short-lived platelet dynamics, as for every model certain assumptions that are not entirely relevant have to be made; this stresses the importance of combining various methods for a comprehensive analysis of a complex phenomenon. Conclusions concerning the function of biological systems should be based on more than one dynamic model or calculation method, since applying only one model (or calculation method) may give artifactual results due to poor statistics of observed data or to inexactness of the assumptions concerning the model

    Full text: Depletion of splenic and hepatic macrophages has potentials to alleviate hemorrhage in patients who suffered from immune thrombocytopenic purpura (ITP). This investigation was aimed to assess whether nanotechnology can play a role in this clinical setting by absorbing bisphosphonate clodronate (CLOD) to type A gelatin nanospheres (GNS) to form CLOD-GNS. First, the stability of CLOD-GNS was assessed in- vitro and up to 6 mg CLOD can be adsorbed in 1 mg GNS. The ability of CLOD-GNS to target the spleen and the liver was then evaluated by biodistribution assay and 99mTc-CLOD-GNS scintigraphy in rats. It showed that up to 70.6% of CLOD-GNS could be accumulated in the liver and spleen. The survival of the macrophages in vitro and the phagocytic ability of hepatic and splenic macrophage in vivo were reduced and later demonstrated by99mTc-phytic colloid scintigraphy. In rats with induced ITP, administration of CLOD-GNS successfully prevented peripheral platelet levels from decreasing. Our preliminary data demonstrate that CLOD-GNS can effectively target the reticuloendothelial system and has potentials in the treatment of ITP warrants further study. (author)

    Splenic artery embolization (SAE) is a common procedure in trauma patients with blunt splenic injuries. We report a case of acute ischemic stroke following orthopedic surgery in a patient with post-SAE reactive thrombocytosis. A 37-year-old woman with idiopathic thrombocytopenic purpura (ITP) suffered from multiple trauma scheduled for open reduction and internal fixation for right tibial and left radius fracture five days after SAE. The patient did not have any thromboembolic complications, although the platelet counts increased from 43 × 10/L to 568 × 10/L within two days after SAE. Surgery was completed under general anesthesia with tracheal intubation without complications. The patient complained of visual loss followed by limb weakness on the fourth and eighth hour postoperatively. Magnetic resonance imaging (MRI) of head demonstrated ischemic change over bilateral basal ganglia, and occipital areas, suggesting the diagnosis of cortical blindness. To suppress platelet count and avoid platelet hyper-aggregation, anti-platelet drug (i.e., oral aspirin 100 mg daily), hydration, and hydroxyurea (i.e., 20 mg/kg daily) were used for the treatment of reactive thrombocytosis. Although right-sided hemiparesis persisted, the patient reported mild visual recovery. She was discharged four months after SAE with active rehabilitation. Our report highlights an increased risk of acute arterial thromboembolic events in patients with reactive thrombocytosis, especially those undergoing surgery.

    NF-κB essential modulator (NEMO) is a component of the IKK complex, which participates in the activation of the NF-κB pathway. Hypomorphic mutations in the IKBKG gene result in different forms of anhidrotic ectodermal dysplasia with immunodeficiency (EDA-ID) in males without affecting carrier females. Here, we describe a hypomorphic and missense mutation, designated c.916G>A (p.D306N), which affects our patient, his mother, and his sister. This mutation did not affect NEMO expression; however, an immunoprecipitation assay revealed reduced ubiquitylation upon CD40-stimulation in the patient's cells. Functional studies have demonstrated reduced phosphorylation and degradation of IκBα, affecting NF-κB recruitment into the nucleus. The patient presented with clinical features of ectodermal dysplasia, immunodeficiency, and immune thrombocytopenic purpura, the latter of which has not been previously reported in a patient with NEMO deficiency. His mother and sister displayed incontinentia pigmenti indicating that, in addition to amorphic mutations, hypomorphic mutations in NEMO can affect females. Copyright © 2015 Elsevier Inc.

    Objective: To investigate the clinical significance of detecting soluble platelet glycocalicin (sGC) and thrombopoietin (TPO) in the differential diagnosis of idiopathic thrombocytopenic purpura (ITP) and aplastic anemia (AA). Methods: Plasma sGC and serum TPO in 83 patients with ITP, 47 patients with AA and 50 normal individuals were detected by iminunoradiometric assay (IRMA) and enzymelinked immunosorbent assay (ELISA), respectively. Statistical analysis was performed using Q test and P value of 0.05). But serum TPO level in AA group was significantly higher than that in ITP and normal groups: (857.43 ± 228.43) ng/L vs (90.32 ± 39.43) ng/L and (70.29 ± 25.16) ng/L, and they were considered statistically significant (Q=24.45 and 18.25, both P < 0.01). Conclusion: Detecting plasma sGC and serum TPO might be helpful for differentiating ITP and AA and for understanding the pathophysiology of thrombocytopenia. (authors)

    Immune thrombocytopenic purpura (ITP) is a common hematological disease treated primarily by corticosteroids. The aim of the present study was to compare response rate between patients, underwent splenectomy vs. rituximab as second-line therapy. Adult patients diagnosed with ITP who did not respond to corticosteroids or relapsed during the period 1990-2014 were included in a quasi-experimental study. Categorical variables were compared using Fisher exact test. Response to treatment was compared using logistic regression. Data were analyzed using SAS V9.2. One-hundred and forty-three patients with ITP were identified through medical records. Of 62 patients treated, 30 (48.38%) required second-line therapy. 19 (63%) patients received rituximab, and 11 (37%) underwent splenectomy. Platelets at diagnosis were not different between study groups (p = 0.062). Splenectomy group patients were younger (p = 0.011). Response to second-line therapy showed no significant difference between two groups (OR 2.03, 95% CI (0.21-22.09), p = 0.549). Results did not show a statistically significant difference in platelet counts over time between treatment groups (p = 0.101). When used exclusively as a second-line therapy for steroid-refractory ITP, the response rate was not statistically different between rituximab and splenectomy. However, further large studies are needed to assess the response rates for these treatment modalities as a second-line therapy.

    The purpose of this study was to report in acute childhood idiopathic thrombocytopenic purpura (ITP) the current practices of French paediatric hematologists and to compare them to recent publications of American and British teams. A questionnaire was sent online to the members of the French Society of Pediatric Hematology/Immunology (SHIP). This questionnaire, adapted from a similar american study conducted in 2001, asked 16 questions based on the clinical presentation of a 5-year-old boy referred for an acute ITP. 59/123 SHIP members responded to the survey. In response to question regarding initial treatment, 86% of physicians would be given active treatments and only 9% would rarely or never administer any drug. When asked which agent would be used in case of treatment, 68% would choose to prescribe intravenous immunoglobulins and 32% corticosteroids, nobody recommended the use of anti-D immunoglobulins. Furthermore, 83% would usually hospitalize such a child. Finally, this study allowed us to update the current French management of treating pediatric ITP which is almost comparable among this subset of pediatric hematologists, but showed some discrepancies comparatively to the American and British studies.

    28 patients with chronic Immunogenic (Idiopathic) Thrombocytopenic purpura (ITP) were determined of the site of sequestration using 99m Tc labeled platelets. Among them, partial splenic artery embolization were done in 20 patients. 7/8 spleen type cases and 1/6 hepato-spleen hepatic type cases have their platelets counts raised above 100 x 10 9 /L. The separation of platelets and its 99m Tc labelling method were also discussed. Above results suggested that the determination of sequestration site of the 99m Tc labelled platelets have some help for the splenic artery embolization therapy in ITP

    Idiopathic thrombocytopenic purpura (ITP) is a blood disorder characterized by an abnormal decrease in the number of platelets in the blood. ITP results from development of an antibody directed against a structural platelet antigen (an autoantibody). Platelets are also called thrombocytes, meaning cells that form clots. The cause of ITP is not known and their diagnosis requires that other disorders be excluded through selective tests. In this work, forty patients suffering from ITP and sixty healthy volunteers (Control Group) were analyzed. All the serum samples had been collected from people who live in the urban area of Rio de Janeiro City/Brazil. Blood was collected into vacutainers without additives. The measurements were performed at the X-ray fluorescence beamline at Brazilian National Synchrotron Light Laboratory (LNLS), in Campinas, Sao Paulo using a monochromatic beam with maximum energy of 20 keV for the excitation and an Ultra-LEGe detector with resolution of 148 eV at 5.9 keV. Standard solutions with Vanadium as internal standard were prepared for calibration system. It was possible to determine the elemental concentrations of the following six elements: Na, P, S, Cl, K and Ca. The Student's t-test was used to analyze significant differences (α = 0.05) between group of patients with ITP and control group. The elements that presented significant differences for the mean of their concentrations between each one of the ITP group and control group in μg.g-1 were: phosphorous (136±12 and 92±12), Sulphur (1077±97 and 847±80), Chlorine (2905±385 and 2266±378), Potassium (137±118 and 82±15) and Calcium (64±7 and 44±6) respectively. These results will help the biomedical field with regard to early diagnosis and improved medical treatment. Thus, our findings indicate that these elements can be related to the important biochemical processes in ITP. (author)

    Kinetics and quantification of the sites of destruction of 111 In-oxine-labeled autologous platelets were investigated in eight patients with idiopathic thrombocytopenic purpura. The mean platelet count was 17 +/- 9 X 10(9)/liter; platelets were separated by differential centrifugation and labeled with 5.6 +/- 2.5 MBq 111 In. Whole body and organ 111 In-platelet distribution was quantitated with a scintillation camera and a computer-assisted imaging system acquisition matrix. Areas of interest were selected with the computer and organ 111 In-radioactivity expressed as a percentage of whole body activity. Mean platelet survival was 49.5 +/- 29.6 hr and the survival curves were exponential. Equilibrium percentage organ 111 In-radioactivity was (normal values in parentheses): spleen 33.7 +/- 8.8 (31.1 +/- 10.2); liver 16.1 +/- 9.5 (13.1 +/- 1.3); thorax 22.8 +/- 3.7 (28.2 +/- 5.6). Percentage organ 111 In-activity at the time when labeled platelets had disappeared from the circulation was: spleen 44.5 +/- 16.4 (40 +/- 16); liver 16.0 +/- 11.5 (32.4 +/- 7.2); thorax 19.7 +/- 6.0 (17.7 +/- 10.3). Thorax activity corresponds to bone marrow radioactivity. Three patterns of platelet sequestration were evident. Three patients had mainly splenic sequestration, two mainly hepatic sequestration, and three diffuse reticuloendothelial system sequestration with a major component of platelets destroyed in the bone marrow. Splenectomy was performed in two patients. The pattern of 111 In-platelet sequestration was not predictive of response of glucocorticoid therapy or indicative of the necessity for splenectomy. Quantitative 111 In-labeled autologous platelet kinetic studies provide a new tool for the investigation of platelet disorders.U

  19. The D173G mutation in ADAMTS-13 causes a severe form of congenital thrombotic thrombocytopenic purpura

    Congenital thrombotic thrombocytopenic purpura (TTP) is a rare form of thrombotic microangiopathy, inherited with autosomal recessive mode as a dysfunction or severe deficiency of ADAMTS-13 (A Disintegrin And Metalloprotease with ThromboSpondin 1 repeats Nr. 13), caused by mutations in the ADAMTS-13 gene. About 100 mutations of the ADAMTS-13 gene were identified so far, although only a few characterised by in vitro expression studies. A new Asp to Gly homozygous mutation at position 173 of ADAMTS-13 sequence was identified in a family of Romanian origin, with some members affected by clinical signs of TTP. In two male sons, this mutation caused a severe (< 3 %) deficiency of ADAMTS-13 activity and antigen level, associated with periodic thrombocytopenia, haemolytic anaemia and mild mental confusion. Both parents, who are cousins, showed the same mutation in heterozygous form. Expression studies of the mutant ADAMTS-13, performed in HEK293 cells, showed a severe decrease of the enzyme’s activity and secretion, although the protease was detected inside the cells. Molecular dynamics found that in the D173G mutant the interface area between the metalloprotease domain and the disintegrin-like domain significantly decreases during the simulations, while the proline-rich 20 residues linker region (LR, 285–304) between them undergoes extensive conformational changes. Inter-domain contacts are also significantly less conserved in the mutant compared to the wild-type. Both a decrease of the inter-domain contacts along with a substantial conformational rearrangement of LR interfere with the proper maturation and folding of the mutant ADAMTS-13, thus impairing its secretion.

    Full Text Available Abstract Background Thrombotic thrombocytopenic purpura and the hemolytic uremic syndrome (TTP-HUS are related and uncommon disorders with a high fatality and complication rate if untreated. Plasma exchange therapy has been shown to produce high response rates and improve survival in patients with many forms of TTP-HUS. We performed a retrospective cohort study of 178 consecutively treated patients with TTP-HUS and analyzed whether clinical or laboratory characteristics could predict for important short- and long-term outcome measures. Results Overall 30-day mortality was 16% (n = 27. 171 patients (96% received plasma exchange as the principal treatment, with a mean of 8 exchanges and a mean cumulative infused volume of 42 ± 71 L of fresh frozen plasma. The rate of complete response was 65% or 55% depending on whether this was defined by a platelet count of 100,000/μl or 150,000/μl, respectively. The rate of relapse was 18%. The Clinical Severity Score did not predict for 30-day mortality or relapse. The time to complete response did not predict for relapse. Renal insufficiency at presentation was associated with a decreased risk of relapse, with each unit increase in serum creatinine associated with a 40% decreased odds of relapse. 72% of our cohort had an idiopathic TTP-sporadic HUS, while 17% had an underlying cancer, received a solid organ transplant or were treated with a mitomycin-based therapy. The estimated overall 5-year survival was 55% and was significantly better in those without serious underlying conditions. Conclusion Plasma exchange therapy produced both high response and survival rates in this large cohort of patients with TTP-HUS. The Clinical Severity Score did not predict for 30-day mortality or relapse, contrary to our previous findings. Interestingly, the presence of renal insufficiency was associated with a decreased risk of relapse. The most important predictor of mortality was the presence or absence of a serious

    Full Text Available Dengue is currently a major public-health problem. Dengue virus (DENV is classified into four distinct serotypes, DENV 1-4. After 28 years of absence, DENV-4 was again detected in Brazil in 2010 in Roraima State, and one year later, the virus was identified in the northern Brazilian states of Amazonas and Pará, followed by Rio de Janeiro and São Paulo. In Minas Gerais, the first confirmed case of DENV-4 occurred in the municipality of Frutal in 2011 and has now been isolated from a growing number of patients. Although DENV-2 is associated with the highest risk of severe forms of the disease and death due to the infection, DENV-4 has also been associated with severe forms of the disease and an increasing risk of hemorrhagic manifestations. Herein, the first fatal case of confirmed DENV-4 in Brazil is reported. The patient was an 11-year-old girl from the municipality of Montes Claros in northern Minas Gerais State, Brazil. She had idiopathic thrombocytopenic purpura as a comorbid condition and presented with a fulminant course of infection, leading to death due to hemorrhagic complications. Diagnosis was confirmed by detection of Dengue-specific antibodies using IgM capture enzyme-linked immunosorbent assay and semi-nested RT-PCR. Primary care physicians and other health-care providers should bear in mind that DENV-4 can also result in severe forms of the disease and lead to hemorrhagic complications and death, mainly when dengue infection is associated with coexisting conditions.

These results will help the biomedical field with regard to early diagnosis and improved medical treatment. Thus, our findings indicate that these elements can be related to the important biochemical processes in ITP. (author)

    To assess the health-related quality of life (HRQOL) of immune thrombocytopenic purpura (ITP) patients. This was a cross-sectional, descriptive study comparing ITP patients' HRQOL to age and gender matched controls. ITP patients from the Platelet Disorder Support Association were recruited until 1000 surveys had been completed. Controls were randomly sampled from the Harris Interactive Online Panel. ITP patients and controls completed a one-time web-based survey, including a comprehensive HRQOL assessment. ITP patients completed the SF-36, the EQ-5D, and the ITP-Patient Assessment Questionnaire (ITP-PAQ). Controls completed the SF-36 and EQ-5D only. ITP patients' SF-36 and EQ-5D scores were compared to controls in unadjusted and adjusted analyses. Associations between splenectomy status, duration of illness, and platelet count with ITP patients' HRQOL scores were also examined. This analysis included 1002 ITP patients and 1031 controls. ITP patients scored worse on seven of eight SF-36 domains and the Physical and Mental Summary scores (all p PAQ scales: Bother, Psychological, Fear, Social Activity, and Work (all p PAQ scales. Lower platelet count was consistently associated with worse ITP-PAQ scores and had weaker associations with SF-36 and EQ-5D scores. ITP was associated with consistent and statistically significant deficits on generic HRQOL measures. The ITP-PAQ demonstrated differences based on disease severity and treatments. The self-selection bias in the two samples limits the generalizability of the results to all patients with ITP. Further research is needed in more generalizable samples.

    Congenital thrombotic thrombocytopenic purpura (TTP) is a rare form of thrombotic microangiopathy, inherited with autosomal recessive mode as a dysfunction or severe deficiency of ADAMTS-13 (A Disintegrin And Metalloprotease with ThromboSpondin 1 repeats Nr. 13), caused by mutations in the ADAMTS-13 gene. About 100 mutations of the ADAMTS-13 gene were identified so far, although only a few characterised by in vitro expression studies. A new Asp to Gly homozygous mutation at position 173 of ADAMTS-13 sequence was identified in a family of Romanian origin, with some members affected by clinical signs of TTP. In two male sons, this mutation caused a severe (< 3 %) deficiency of ADAMTS-13 activity and antigen level, associated with periodic thrombocytopenia, haemolytic anaemia and mild mental confusion. Both parents, who are cousins, showed the same mutation in heterozygous form. Expression studies of the mutant ADAMTS-13, performed in HEK293 cells, showed a severe decrease of the enzyme’s activity and secretion, although the protease was detected inside the cells. Molecular dynamics found that in the D173G mutant the interface area between the metalloprotease domain and the disintegrin-like domain significantly decreases during the simulations, while the proline-rich 20 residues linker region (LR, 285–304) between them undergoes extensive conformational changes. Inter-domain contacts are also significantly less conserved in the mutant compared to the wild-type. Both a decrease of the inter-domain contacts along with a substantial conformational rearrangement of LR interfere with the proper maturation and folding of the mutant ADAMTS-13, thus impairing its secretion.

    Splenectomy is the only potentially curative treatment for chronic immune thrombocytopenic purpura (ITP) in adults. However, one-third of the patients relapse without predictive factors identified. We evaluate the predictive value of the site of platelet sequestration on the response to splenectomy in patients with ITP. Eighty-two consecutive patients with ITP treated by splenectomy between 1992 and 2013 were retrospectively reviewed. Platelet sequestration site was studied by (111)Indium-oxinate-labeled platelets in 93% of patients. Response to splenectomy was defined at last follow-up as: complete response (CR) for platelet count (PC) ≥100 × 10(9)/L, response (R) for PC≥30 × 10(9)/L and splenectomy was performed in 81 patients (conversion rate of 16%), and open approach in one patient. Median follow-up was 57 months (range, 1-235). Platelet sequestration study was performed in 93% of patients: 50 patients (61%) exhibited splenic sequestration, 9 (11%) hepatic sequestration and 14 patients (17%) mixed sequestration. CR was obtained in 72% of patients, R in 25% and NR in 4% (two with splenic sequestration, one with hepatic sequestration). Preoperative PC, age at diagnosis, hepatic sequestration and male gender were significant for predicting CR in univariate analysis, but only age (HR = 1.025 by one-year increase, 95% CI [1.004-1.047], p = 0.020) and pre-operative PC (HR = 0.112 for > 100 versus splenectomy was independent of the site of platelet sequestration in patients with ITP. Pre-operative platelet sequestration study in these patients cannot be recommended.

    The localized scleroderma (LS) known as morphea, presents a variety of clinical manifestations that can include systemic involvement. Current classification schemes divide morphea into categories based solely on cutaneous morphology, without reference to systemic disease or autoimmune phenomena. This classification is likely incomplete. Autoimmune phenomena such as vitiligo and Hashimoto thyroiditis associated with LS have been reported in some cases suggesting an autoimmune basis. To our knowledge this is the first case of a morphea forming part of a multiple autoimmune syndrome (MAS) and presenting simultaneously with autoimmune thrombocytopenic purpura and central nervous system vasculitis. We report an uncommon case of a white 53 year old female patient with LS as part of a multiple autoimmune syndrome associated with pneumonitis, autoimmune thrombocytopenic purpura and central nervous system vasculitis presenting a favorable response with thrombopoietin receptor agonists, pulses of methylprednisolone and cyclophosphamide. Is likely that LS have an autoimmune origin and in this case becomes part of MAS, which consist on the presence of three or more well-defined autoimmune diseases in a single patient.

    Henoch-Schönlein purpura is a relatively common vasculitis mainly affecting children. It is characterized by purpuric skin rash, abdominal cramping, and haematuria. Skin biopsies taken from Henoch-Schönlein purpura lesions disclose perivascular IgA deposits. FMF is an autoinflammatory disease characterized by recurrent attacks of fever lasting 2-3 days which resolve spontaneously. Typical manifestations of the disease are peritonitis, pleuritis, pericarditis, arthritis and erysipelas-like erythema usually affecting the lower limbs. Over the years many reviews emphasized the clinical impression that Henoch-Schönlein purpura is more common among FMF patients than in healthy control population. In this review we summarize these reports and show that sometimes Henoch-Schönlein purpura associated with FMF differs from typical isolated Henoch-Schönlein purpura, and this is also the case with polyarteritis nodosa and SpA associated with FMF. It is suggested that these clinical manifestations (polyarteritis nodosa, Henoch-Schönlein purpura and SpA) should be considered to be associated with FMF as part of what we call FMF rather than as co-existing additional separate clinical entities. © The Author 2015.

    The occurrence of a hypercoagulable state and decreasing concentration of ADAMTS 13 in late pregnancy and during the postpartum period increases the risk for a woman to develop life-threatening thrombotic thrombocytopenic purpura (TTP). This is also the time of great risk for the more common obstetric complications of preeclampsia; eclampsia; and hemolysis, elevated liver functions tests, low platelets (HELLP) syndrome. These conditions are associated with high maternal and perinatal mortality. Differential diagnosis may be difficult due to the overlapping of clinical and laboratory findings, including thrombocytopenia, microangiopathic hemolytic anemia, neurologic symptoms, and renal insufficiency, making it difficult or impossible to distinguish them from TTP. Management of microangiopathic disorders encountered during pregnancy differ; therefore, an accurate diagnosis is required. Outcomes of TTP without plasma exchange therapy (TPE) are almost uniformly fatal. Early recognition and management of symptoms with prompt and aggressive TPE is essential when TTP is suspected.

    Melioidosis is an established endemic infection in Sri Lanka, caused by Burkholderia pseudomallei, a gram negative bacterium distributed in saprophytes in soil and surface water. Main mode of transmission is via percutaneous inoculation. Pneumonia is the most common presentation in acute disease. We report a 33 year old previously healthy Sinhalese female with an occupational exposure to surface water in paddy fields, who was on postpartum day 6 following an uncomplicated pregnancy and delivery via an elective caesarian section. She presented with a 1 day history of breathlessness, preceded by a brief episode of fever. She had occasional right side coarse crackles and pitting oedema of both lower limbs. Shortly after admission, she developed type one respiratory failure needing invasive mechanical ventilation. Initial chest x-ray revealed slight obliteration of right medial diaphragmatic border while echocardiogram revealed moderate pulmonary hypertension. Computed tomography pulmonary angiogram excluded a pulmonary embolism, but revealed bilateral multi-lobar consolidation. Abdominal computed tomography demonstrated bilateral pyelonephritis with renal abscesses. As initial cultures were inconclusive, melioidosis antibody levels were done due to high degree of suspicion, which was found to be positive with a titer of 1:2560. A diagnosis of melioidosis was made based on the suggestive clinical picture, exposure history and the highly positive antibody level. She developed left side focal seizures together with thrombocytopenia and microangiopathic haemolytic anemia, suggestive of thrombotic thrombocytopenic purpura. Magnetic resonance imaging of brain was negative for cerebral abscesses but revealed extensive minute haemorrhagic foci throughout the cerebrum. Thus, the final diagnosis was acute melioidosis causing pneumonia and renal abscesses, complicated with thrombotic thrombocytopenic purpura and sepsis. She demonstrated dramatic response to high dose meropenem

  13. Platelet turnover and kinetics in immune thrombocytopenic purpura: results with autologous 111In-labeled platelets and homologous 51Cr-labeled platelets differ

    Mean platelet survival and turnover were simultaneously determined with autologous 111In-labeled platelets (111In-AP) and homologous 51Cr-labeled platelets (51Cr-HP) in ten patients with chronic immune thrombocytopenic purpura (ITP). In vivo redistribution of the 111In-AP was quantitated with a scintillation camera and computer-assisted image analysis. The patients were divided into two groups: those with splenic platelet sequestration (spleen-liver 111In activity ratio greater than 1.4), and those with diffuse sequestration in the reticuloendothelial system. The latter patients had more severe ITP reflected by pronounced thrombocytopenia, decreased platelet turnover, and prominent early hepatic platelet sequestration. Mean platelet life span estimated with 51Cr-HP was consistently shorter than that of 111In-AP. Platelet turnover determined with 51Cr-HP was thus over-estimated. The difference in results with the two isotope labels was apparently due to greater in vivo elution of 51Cr. Although the limitations of the techniques should be taken into account, these findings indicate that platelet turnover is not always normal or increased in ITP, but is low in severe disease. We suggest that this may be ascribed to damage to megakaryocytes by antiplatelet antibody. The physical characteristics in 111In clearly make this radionuclide superior to 51Cr for the study of platelet kinetics in ITP

    Currently under codevelopment by Symphogen and Swedish Orphan Biovitrum, rozrolimupab is the first in a new class of recombinant polyclonal antibodies, known as symphobodies, produced using a proprietary technology from Symphogen. Rozrolimupab is being investigated for the prevention of hemolytic disease of the fetus and newborn (HDFN) and for the treatment of idiopathic thrombocytopenic purpura (ITP). Rozrolimupab comprises 25 genetically unique IgG1 antibodies, all of which are specific for the rhesus D (RhD) erythrocyte protein. In preclinical studies, rozrolimupab demonstrated binding to erythrocytes that was comparable with that of two plasma-derived anti-D Ig preparations. In a phase I clinical trial in healthy male volunteers, treatment with rozrolimupab was not associated with serious adverse events. In a phase II clinical trial of rozrolimupab in healthy, male, RhD-negative volunteers, rozrolimupab dose-dependently cleared RhD-positive erythrocytes from the circulation. Phase II clinical trials in ITP and HDFN are currently ongoing. Phase III clinical trials are necessary to establish the efficacy and safety profile of rozrolimupab compared with standard plasma-derived anti-D Ig preparations.

    Diagnosis and management of immune thrombocytopenic purpura (ITP) remain largely dependent on clinical expertise and observations more than on evidence derived from clinical trials of high scientific quality. One major obstacle to the implementation of such studies and in producing reliable meta-analyses of existing data is a lack of consensus on standardized critical definitions, outcome criteria, and terminology. Moreover, the demand for comparative clinical trials has dramatically increased since the introduction of new classes of therapeutic agents, such as thrombopoietin receptor agonists, and innovative treatment modalities, such as anti-CD 20 antibodies. To overcome the present heterogeneity, an International Working Group of recognized expert clinicians convened a 2-day structured meeting (the Vicenza Consensus Conference) to define standard terminology and definitions for primary ITP and its different phases and criteria for the grading of severity, and clinically meaningful outcomes and response. These consensus criteria and definitions could be used by investigational clinical trials or cohort studies. Adoption of these recommendations would serve to improve communication among investigators, to enhance comparability among clinical trials, to facilitate meta-analyses and development of therapeutic guidelines, and to provide a standardized framework for regulatory agencies.

    Full Text Available Abstract Background Immune thrombocytopenic purpura (ITP, a condition characterized by autoimmune-mediated platelet destruction and suboptimal platelet production, is associated with symptoms such as bruising, epistaxis, menorrhagia, mucosal bleeding from the gastrointestinal and urinary tracts and, rarely central nervous system bleeding. The aim of this research is to develop a conceptual model to describe the impact of ITP and its treatment on patients' health-related quality of life (HRQoL. Methods A literature search and focus groups with adult ITP patients were conducted to identify areas of HRQoL affected by ITP. Published literature was reviewed to identify key HRQoL issues and existing questionnaires used to assess HRQoL. Focus group transcripts were reviewed, and common themes were extracted by grouping conceptual categories that described the impact on HRQoL. Results The literature synthesis and themes from the focus group data suggest that decreased platelet counts, disease symptoms, and treatment side effects influence multiple domains of HRQoL for ITP patients. Key areas affected by ITP and its treatments include emotional and functional health, work life, social and leisure activities, and reproductive health. Conclusion ITP affects various areas of HRQoL. This conceptual model will help inform the evaluation of therapeutic strategies for ITP.

    Thienopyridine-derivatives (ticlopidine, clopidogrel, and prasugrel) are the primary antiplatelet agents. Thrombotic thrombocytopenic purpura (TTP) is a rare drug-associated syndrome, with the thienopyridines being the most common drugs implicated in this syndrome. We reviewed 20 years of information on clinical, epidemiologic, and laboratory findings for thienopyridine-associated TTP. Four, 11, and 11 cases of thienopyridine-associated TTP were reported in the first year of marketing of ticlopidine (1989), clopidogrel (1998), and prasugrel (2010), respectively. As of 2011, the FDA received reports of 97 ticlopidine-, 197 clopidogrel-, and 14 prasugrel-associated TTP cases. Severe deficiency of ADAMTS-13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) was present in 80% and antibodies to 100% of these TTP patients on ticlopidine, 0% of the patients with clopidogrel-associated TTP (p < 0.05), and an unknown percentage of patients with prasugrel-associated TTP. TTP is associated with use of each of the three thienopyridines, although the mechanistic pathways may differ. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    Full Text Available We report the case of an African American male with no significant past medical history presenting with recurrent, rapidly relapsing episodes of thrombotic thrombocytopenic purpura (TTP despite aggressive treatment with several lines of treatment. Incidentally, these episodes were associated with severe abdominal pain which eventually developed into acute abdomen and prompted exploratory laparotomy, revealing diffuse carcinomatosis with a tumor located on the left pelvis that was encasing the distal sigmoid colon. Pathology made a final diagnosis of peritoneal mesothelioma. TTP-like syndrome (TTP-LS has been described as a paraneoplastic phenomenon in several malignancies but never before in the setting of malignant mesothelioma. Paraneoplastic TTP-like syndrome has historically been associated with a dismal prognosis and particular clinical and laboratory abnormalities described in this paper. It is of utmost importance to make a prompt determination whether TTP is idiopathic or secondary to an underlying condition because of significant differences in their prognosis, treatment, and response. This paper also reviews the current literature regarding this challenging condition.

    Deficiency of the von Willebrand factor-cleaving protease ADAMTS13 is central to the pathophysiology of thrombotic thrombocytopenic purpura (TTP), a microangiopathic syndrome that presents as an acute medical emergency. In this review we will explore the evidence of a two-way relationship between TTP and ACS. Moreover, we will review the evidence emerged from epidemiological studies of an inverse relationship between the plasma levels of ADAMTS13 and the risk of ACS. Pubmed, MEDLINE and EMBASE, CINHAL, COCHRANE and Google Scholar databases were searched from inception to January 2017. The search yielded 43 studies representing 23 unique patient cases, 5 case series, 5 cohort studies and 10 case-control studies. Most ACS cases developing in the setting of TTP resolved with standard treatment of the underlying microangiopathy, with only a few requiring coronary invasive management. Antiplatelet therapy was not usually prescribed and all of the currently used P2Y 12 were felt to be a potential trigger for a TTP-like syndrome, although our review revealed that the occurrence of TTP in patients treated with new P2Y 12 antagonists is rare. Most studies confirmed the inverse association among ADAMTS13 levels and ACS. The heart is a definite target organ in TTP. The clinical spectrum of its involvement is probably influenced by local factors that add on to the systemic deficiency characteristic of TTP. It follows that patients with TTP should be carefully monitored for ACS events, especially when multiple risk factors for coronary disease exist. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Cardiac involvement is a major cause of mortality in patients with thrombotic thrombocytopenic purpura (TTP). However, diagnosis remains underestimated and delayed, owing to subclinical injuries. Cardiac troponin-I measurement (cTnI) on admission could improve the early diagnosis of cardiac involvement and have prognostic value. To assess the predictive value of cTnI in patients with TTP for death or refractoriness. The study involved a prospective cohort of adult TTP patients with acquired severe ADAMTS-13 deficiency ( 0.1 μg L(-1) ) was present in 78 patients (59%), of whom 46 (59%) had no clinical cardiac involvement. The main outcomes were death (25%) and refractoriness (17%). Age (P = 0.02) and cTnI level (P = 0.002) showed the greatest impact on survival. A cTnI level of > 0.25 μg L(-1) was the only independent factor in predicting death (odds ratio [OR] 2.87; 95% confidence interval [CI] 1.13-7.22; P = 0.024) and/or refractoriness (OR 3.03; 95% CI 1.27-7.3; P = 0.01). A CTnI level of > 0.25 μg L(-1) at presentation in patients with TTP appears to be an independent factor associated with a three-fold increase in the risk of death or refractoriness. Therefore, cTnI level should be considered as a prognostic indicator in patients diagnosed with TTP. © 2014 International Society on Thrombosis and Haemostasis.

    Idiopathic thrombocytopenic purpura (ITP) is a chronic disease which is accompanied with hopelessness and loss of the sense of well-being due to its symptoms and treatment. It also affects patients' sense of social and spiritual well-being. This disorder decreases patients' self-esteem and their quality of life by changing their mental image and self-confidence. This study was performed to find the relationship between self-esteem and quality of life of patients with ITP. This was a descriptive-analytical study on 64 patients with ITP who referred to Isfahan's Sayed Al-Shohada Hospital, Iran. In this study, patients with ITP were selected randomly using a random number chart. The data collection tools consisted of the World Health Organization Quality of Life (WHOQOL)-BREF and Coopersmith Self-esteem Inventory (CSEI). Data were analyzed using SPSS and chi-square and Mann-Whitney tests and the Pearson and Spearman's rank correlation coefficients. In total, 64 patients completed the questionnaires. RESULTS showed that 32% of subjects were over 36 years of age and 59% were women. In addition, 29.7% of ITP patients had low self-esteem and quality of life. Chi-square test showed a significant relationship between self-esteem and quality of life of patients with ITP. The results of the present study showed that considerable attention must be paid to self-esteem, as one of the most important factors influencing the promotion of quality of life. Therefore, it is suggested that patient's self-esteem be improved by the implementation of educational and psychological programs in order to decrease the consequences of poor quality of life.

    Full Text Available Introduction: Thrombotic thrombocytopenic purpura (TTP is a rare, life-threatening syndrome characterized by microangiopathic anemia, thrombocytopenia, diffuse microvascular thrombosis, and ischemia. It is associated with very low levels of ADAMTS-13. Measurement of ADAMTS-13 levels is used for diagnostic and prognostic purposes, but in every-day clinical practice, this type of analysis is not always readily available. In this retrospective study, we evaluated prognostic value of clinical and laboratory findings in patients with TTP. Materials and methods: We retrospectively investigated patients with clinically diagnosed TTP treated in a unit of Internal and Emergency Medicine (1996-2007. Clinical and laboratory findings were collected and analyzed in order to assess their ability to predict in-hospital death. Results: Twelve patients were identified (mean age 59 + 22 years; 58% were women. Five (42% died during the hospitalization, and the variables significantly associated with this outcome were: a delay between diagnosis and symptom onset (HR 1.36; 95% CI 1.04-1.78; p < 0.05; a higher severity score (HR 1.48; 95%CI 1,23-3.86; p < 0.05; hemodynamic instability with hypotension and/or shock (HR 3.35; 95%CI 3.02-9.26; p < 0.01; a higher schistocyte count on blood smear (HR 1.84; 95%CI 1.04-3.27; p < 0.05; and higher lactate values (HR 1.85; 95%CI 1.08- 3.16; p < 0.05. Conclusions: TTP is a rare and potentially fatal disease with protean manifestations. Delayed diagnosis after symptom onset is a major determinant of poor outcome. Hypotension and shock are also prognostically unfavourable. Laboratory evidence of cardiocirculatory compromise (i.e., elevated lactate levels and extension of the disease process (i.e., schistocyte count > 3 are predictive of in-hospital death, independently of the hemodynamic profile on admission.

    The cannabinoid system is involved in the immune regulation by modulation of Th cells type 1 and 2. It is composed of the CB2 receptor which is expressed at 10 to 100 folds greater levels on immune cells than the CB1 receptors. The CB2 is encoded by the cannabinoid CB receptor gene (CNR2) gene. This study aims to investigate the polymorphism in CNR2 gene variation rs 35761398 (Q63R) in Egyptian children with immune thrombocytopenic purpura and to investigate the relation between this gene polymorphism and either the susceptibility to or the chronicity of the disease. Forty children diagnosed as ITP were included in this study and 20 healthy children as normal control. CNR2 gene was investigated in those children by PCR RFLP technique (restriction fragment length polymorphism). CNR2 genotyping revealed that 45% of ITP patients had the QR heterotype, 50% had the RR homotype and 5% had QQ, the wild type with significantly higher frequency of homomutant genotype in comparison to controls. The relative odds ratio suggested a double risk for developing ITP in RR homotype (OR 2.152). A significant overpresentation of the RR genotype and of R allele was observed in the chronic patients (P=0.002 and 0.003, respectively). The associated risk to develop chronic ITP increased more than two folds for the RR homotype (OR=2.854). In conclusion, this study confirms the role of CNR2 Q63R polymorphism in the susceptibility to ITP in children and chronicity of the disease. Copyright© by the Egyptian Association of Immunologists.

    Eltrombopag is an oral, non-peptide, thrombopoietin-receptor agonist that stimulates thrombopoiesis, leading to increased platelet production. This study assessed the efficacy, safety, and tolerability of once daily eltrombopag 50 mg, and explored the efficacy of a dose increase to 75 mg. In this phase III, randomised, double-blind, placebo-controlled study, adults from 63 sites in 23 countries with chronic idiopathic thrombocytopenic purpura (ITP), platelet counts less than 30 000 per muL of blood, and one or more previous ITP treatment received standard care plus once-daily eltrombopag 50 mg (n=76) or placebo (n=38) for up to 6 weeks. Patients were randomly assigned in a 2:1 ratio of eltrombopag:placebo by a validated randomisation system. After 3 weeks, patients with platelet counts less than 50 000 per microL could increase study drug to 75 mg. The primary endpoint was the proportion of patients achieving platelet counts 50 000 per microL or more at day 43. All participants who received at least one dose of their allocated treatment were included in the analysis. This study is registered with ClinicalTrials.gov, number NCT00102739. 73 patients in the eltrombopag group and 37 in the placebo group were included in the efficacy population and were evaluable for day-43 analyses. 43 (59%) eltrombopag patients and six (16%) placebo patients responded (ie, achieved platelet counts >/=50 000 per microL; odds ratio [OR] 9.61 [95% CI 3.31-27.86]; ptime during the study than did those receiving placebo (OR 0.49 [95% CI 0.26-0.89]; p=0.021). The frequency of grade 3-4 adverse events during treatment (eltrombopag, two [3%]; placebo, one [3%]) and adverse events leading to study discontinuation (eltrombopag, three [4%]; placebo, two [5%]), were similar in both groups. Eltrombopag is an effective treatment for managment of thrombocytopenia in chronic ITP.

    In this study, we examined the length of stay, hospitalization cost, and risk of in-hospital mortality among US adult inpatients with immune thrombocytopenic purpura (ITP). We analyzed nationally representative data obtained from Nationwide/National Inpatient Sample database of discharges from 2006 to 2012. In the US, there were an estimated 296,870 (95% confidence interval [CI]: 284,831-308,909) patient discharges recorded for ITP from 2006 to 2012, during which ITP-related hospitalizations had increased steadily by nearly 30%. The average length of stay for an ITP-related hospitalization was found to be 6.02 days (95% CI: 5.93-6.10), which is 28% higher than that of the overall US discharge population (4.70 days, 95% CI: 4.66-4.74). The average cost of ITP-related hospitalizations was found to be US$16,594 (95% CI: US$16,257-US$16,931), which is 48% higher than that of the overall US discharge population (US$11,200; 95% CI: US$11,033-US$11,368). Gender- and age-adjusted mortality risk in inpatients with ITP was 22% (95% CI: 19%-24%) higher than that of the overall US discharge population. Across diagnosis related groups, length of stay for ITP-related hospitalizations was longest for septicemia (7.97 days, 95% CI: 7.55-8.39) and splenectomy (7.40 days, 95% CI: 6.94-7.86). Splenectomy (US$25,262; 95% CI: US$24,044-US$26,481) and septicemia (US$18,430; 95% CI: US$17,353-US$19,507) were associated with the highest cost of hospitalization. The prevalence of mortality in ITP-related hospitalizations was highest for septicemia (11.11%, 95% CI: 9.60%-12.63%) and intracranial hemorrhage (9.71%, 95% CI: 7.65%-11.77%). Inpatients with ITP had longer hospital stay, bore higher costs, and faced greater risk of mortality than the overall US discharge population.

    No validated disease-specific measures are available to assess health-related quality of life (HRQoL) in adult subjects with immune thrombocytopenic purpura (ITP). Therefore, we sought to develop and validate the ITP-Patient Assessment Questionnaire (ITP-PAQ) for adult subjects with ITP. Information from literature reviews, focus groups with subjects, and clinicians were used to develop 50 ITP-PAQ items. Factor analyses were conducted to develop the scale structure and reduce the number of items. The final 44-item ITP-PAQ, which includes ten scales [Symptoms (S), Bother-Physical Health (B), Fatigue/Sleep (FT), Activity (A), Fear (FR), Psychological Health (PH), Work (W), Social Activity (SA), Women's Reproductive Health (RH), and Overall (QoL)], was self-administered to adult ITP subjects at baseline and 7-10 days later. Test-retest reliability, internal consistency reliability, construct and known groups validity of the final ITP-PAQ were evaluated. Seventy-three subjects with ITP completed the questionnaire twice. Test-retest reliability, as measured by the intra-class correlation, ranged from 0.52-0.90. Internal consistency reliability was demonstrated with Cronbach's alpha for all scales above the acceptable level of 0.70 (range: 0.71-0.92), except for RH (0.66). Construct validity, assessed by correlating ITP-PAQ scales with established measures (Short Form-36 v.1, SF-36 and Center for Epidemiologic Studies Depression Scale, CES-D), was demonstrated through moderate correlations between the ITP-PAQ SA and SF-36 Social Function scales (r = 0.67), and between ITP-PAQ PH and SF-36 Mental Health Scales (r = 0.63). Moderate to strong inter-scale correlations were reported between ITP-PAQ scales and the CES-D, except for the RH scale.

Crianças com doenças auto-imunes apresentam maior probabilidade de desenvolver doenças linfoproliferativas, podendo ocorrer antes, durante ou após o aparecimento da neoplasia. A associação de púrpura trombocitopênica idiopática e linfomas é infreqüente (3%, principalmente na faixa etária pediátrica. Duas teorias tentam explicar a origem desta associação. Na primeira, a trombocitopenia seria decorrente da produção de auto-anticorpos antiplaquetas pelo clone tumoral. Na segunda, a PTI seria resultado de um estímulo antigênico persistente, secundário a uma desordem na proliferação linfóide. O objetivo do presente trabalho foi relatar a associação infreqüente na infância entre púrpura trombo-citopênica idiopática e linfoma não-Hodgkin de células T.Lymphomas represent 10% of all malignant tumors in childhood and from these non-Hodgkin's lymphomas are the most frequent. Children who have autoimmune diseases have a higher probability of developing lymphoproliferative diseases, which can happen before, during or after the appearance of the neoplasia. The association between idiopathic thrombocytopenic purpura and lymphomas is not common (3% especially in children. Two theories try to explain the origin of this association. In the first one, the thrombocytopenia would be a result of an autoantibody anti-blood platelet production by the tumoral clone. In the second one, the idiopathic thrombocytopenic purpura would be a result of a persistent antigenic stimulus subordinate to a disorder in the lymphoid proliferation. The aim of this work is to report the unusual association between idiopathic thrombocytopenic purpura and T-cell non-Hodgkin's lymphoma in childhood.

    The Immune Thrombocytopenic Purpura Patient Assessment Questionnaire (ITP-PAQ) was developed to assess disease-specific quality of life (QoL) in adults with ITP. It is a 44-item questionnaire that includes scales for physical health (symptoms, fatigue/sleep, bother, and activity), emotional health (psychological and fear), overall QoL, social activity, women's reproductive health, and work. A previous study reported preliminary evidence of its reliability and validity. The present study was conducted to ascertain the responsiveness (ability to detect a clinically important treatment effect), reliability, and validity of the ITP-PAQ and to corroborate the earlier findings. The women's reproductive health scale was evaluated for psychometric evidence of the existence of separate menstrual symptoms and fertility subscales. The ITP-PAQ was evaluated in the context of an ongoing open-label extension study assessing the tolerability and durability of increases in the platelet count with AMG 531 (a thrombopoiesis peptibody that increases platelet production by targeting the thrombopoietin receptor) administered by subcutaneous injection once weekly in adult patients with ITP It was self-administered at baseline and at weeks 4, 12, and 24. The responsiveness of the questionnaire was evaluated by calculating and comparing the change scores of patients who showed clinical improvement-categorized as platelet responders (those with a platelet count > or =50 x 10(9) cells/L and a doubling of baseline values at week 24) and durable platelet responders (those with a platelet count > or =50 x 10(9) cells/L and a doubling of baseline values on > or =6 occasions during weeks 17-24)-with the change scores of patients wh did not show clinical improvement. The reliability (internal consistency and test-retest) and validity (convergent, discriminant, and known groups) of the questionnaire were also evaluated. Validity was examined in terms of correlations between the ITP-PAQ and the 36

    Congenital amegakaryocytic thrombocytopenia (CAMT) is a rare, autosomal recessive disorder induced by mutations of the gene coding for thrombopoietin (TPO) receptor (c-MPL) despite high levels of serum TPO. Patients initially present with isolated thrombocytopenia that subsequently progresses into pancytopenia. Although the mechanisms leading to aplasia are unknown, the age of onset has been reported to depend on the severity of the c-MPL functional defect. The primary treatment for CAMT is bone marrow transplantation. This report describes a newborn girl who presented to us with symptoms of sepsis but septic profile came negative except thrombocytopenia. Bone marrow biopsy was done for thrombocytopenia which revealed amegakaryocytic thrombocytopenia. She was given prednisolone. (author)

The aim of this study was to investigate the role of tumor necrosis factor-alpha (TNF-α -308 G/A and transforming growth factor-beta 1 (TGF-β1 –915 G/C polymorphisms in the development and clinical progression of childhood ITP.Materials and Methods: In all, 50 pediatric patients with ITP (25 with acute ITP and 25 with chronic ITP and 48 healthy controls were investigated via LightCycler® PCR analysis for TNF-α -308 G/A and TGF-β1 -915 G/C polymorphisms.Results: The frequency of TNF-α -308 G/A polymorphism was 20%, 16%, and 22.9% in the acute ITP patients, chronic ITP patients, and controls, respectively (p>0.05. The frequency of TGF-β1 -915 G/C polymorphism was 16%, 8%, and 8.3% in the acute ITP patients, chronic ITP patients, and controls, respectively (p>0.05. The risk of developing ITP and clinical progression were not associated with TNF-α -308 G/A (OR: 0.738, 95% CI: 0.275-1.981, and OR: 0.762, 95% CI: 0.179-3.249 or TGF-β1 -915 G/C (OR: 1.5, 95% CI: 0.396-5.685, and OR: 0.457, 95% CI: 0.076-2.755 polymorphisms. Conclusion: The frequency of TNF-α -308 G/A and TGF-β1 -915 G/C polymorphisms did not differ between pediatric ITP patients and healthy controls, and these polymorphisms were not associated with susceptibility to the development and clinical progression of the disease.

    Chronic immune thrombocytopenia purpura (ITP) is an autoimmune disease that exhibits an abnormally high Th1/Th2 ratio. Granulocyte colony-stimulating factor (G-CSF) has been shown to decrease the Th1/Th2 ratio in healthy donors. In this study, we investigated the effects of G-CSF treatment on the Th1/Th2 cells and the underlying mechanisms in patients with ITP in vitro. Peripheral blood mononuclear cells (PBMCs) isolated from patients with ITP and healthy controls were treated with G-CSF. Expression levels of interferon (IFN)-γ, interleukin (IL)-2, IL-4, and IL-13 in supernatants were measured by enzyme-linked immunosorbent assays. The expression of IFN-γ, IL-4, and G-CSF receptor (G-CSFR) on Th1 and Th2 cells were examined by flow cytometry and confocal microscopy. The mRNA expression of IFN-γ, IL-2, IL-4, IL-13, and T-box expressed in T cells (T-bet) and GATA-binding protein 3 (GATA-3) in PBMCs was evaluated by reverse transcription polymerase chain reaction. The results showed that G-CSF could significantly reduce the Th1/Th2 ratio in PBMCs from patients with ITP in vitro. As the concentration of G-CSF increased, Th1/Th2 ([IFN-γ+IL-2]/[IL-4+IL-13]) cytokine ratios and T-bet/GATA-3 mRNA ratios decreased in a concentration-dependent manner. Th1 cells and Th2 cells both expressed G-CSFR. These results suggest that G-CSF could decrease the Th1/Th2 ratio in the context of ITP, and elucidate the direct and indirect immunomodulatory mechanisms underlying G-CSF functions in Th1/Th2 cells, thus supporting the therapeutic potential of G-CSF in the treatment of patients with ITP.

    Full Text Available Abstract Foetal/neonatal alloimmune thrombocytopaenia (NAIT results from maternal alloimmunisation against foetal platelet antigens inherited from the father and different from those present in the mother, and usually presents as a severe isolated thrombocytopaenia in otherwise healthy newborns. The incidence has been estimated at 1/800 to 1/1 000 live births. NAIT has been considered to be the platelet counterpart of Rh Haemolytic Disease of the Newborn (RHD. Unlike RHD, NAIT can occur during a first pregnancy. The spectrum of the disease may range from sub-clinical moderate thrombocytopaenia to life-threatening bleeding in the neonatal period. Mildly affected infants may be asymptomatic. In those with severe thrombocytopaenia, the most common presentations are petechiae, purpura or cephalohaematoma at birth, associated with major risk of intracranial haemorrhage (up to 20% of reported cases, which leads to death or neurological sequelae. Alloimmune thrombocytopaenia is more often unexpected and is usually diagnosed after birth. Once suspected, the diagnosis is confirmed by demonstration of maternal antiplatelet alloantibodies directed against a paternal antigen inherited by the foetus/neonate. Post-natal management involves transfusion of platelets devoid of this antigen, and should not be delayed by biological confirmation of the diagnosis (once the diagnosis is suspected, especially in case of severe thrombocytopaenia. Prompt diagnosis and treatment are essential to reduce the chances of death and disability due to haemorrhage. Due to the high rate of recurrence and increased severity of the foetal thrombocytopaenia in successive pregnancies, antenatal therapy should be offered. However, management of high-risk pregnancies is still a matter of discussion.

    Recreational or regular physical and sport activities may be responsible for a wide range of cutaneous complications. Among them, "sports purpura" is a peculiar symptom that can occur during a large number of sports. "Effort purpura" defines any purpura occurring within the context of physical exercise irrespective of its cause. Therefore this clinical diagnosis includes various aetiologies. Diagnosis of traumatic purpura is often easy if the sport is mentioned in the anamnesis; cutaneous exercise - induced vasculitis must be also noted. Purpura can reveal systemic diseases or internal haemorrhage, such as spleen rupture, thrombopathies or systemic vasculitis, and other effort purpuras must be taken into account, including those related to the environment (cold, sun exposure...). Knowledge of a physical activity before the occurrence of purpura should be known by practitioner to avoid unnecessary and costly explorations in most of the cases.

O paciente do gênero masculino apresentava hemiparesia e proteinúria, e a paciente do gênero feminino tinha cefaleia persistente e hematúria. Ambos foram tratados com metilprednisolona endovenosa e plasmaferese quando do diagnóstico de PPT. Após tratamento, não houve recidiva da PTT, e hematócritos, contagens de plaquetas e níveis de desidrogenase lática permaneceram normais. Em conclusão, a PTT é uma rara e grave manifestação no início do LESJ.

Aproximadamente 60% dos casos de SHU atípica têm mutações do tipo "perda da função" em genes que codificam as proteínas reguladoras do complemento, as quais protegem as células hospedeiras da ativação do complemento: fator H do complemento (FHC, fator I (FIC e proteína cofator de membrana (PCM ou CD46, ou mutações do tipo "ganho da função" em genes que codificam o FHC ou C3. Além disso, aproximadamente 10% dos pacientes com SHU atípica têm deficiência na função do FHC devido a anticorpos anti-FHC. Mesmo que as MATs sejam condições altamente heterogêneas, um terço dos pacientes tem deficiência severa da ADA-MTS13. Transfusões de plaquetas são contraindicadas nesses pacientes. Infusão de plasma ou plasma exchange (PE é o único tratamento eficiente.Thrombotic microangiopathies (TMAs are pathological conditions characterized by generalized microvascular occlusion by platelet thrombi, thrombocytopenia, and microangiopathic hemolytic anemia. Two typical phenotypes of TMAs are hemolytic- uremic syndrome (HUS and thrombotic thrombocytopenic purpura (TTP. Other disorders occasionally present with similar manifestations. Depending on whether renal or brain lesions prevail, two pathologically indistinguishable but somehow clinically different disorders have been described: HUS and TTP. Injury to the endothelial cell is the central and likely inciting factor in the sequence of events leading to TMA. Loss of physiological thromboresistance, leukocyte adhesion to damaged endothelium, complement consumption, abnormal von Willebrand factor release and fragmentation, and increased vascular shear stress may then sustain and amplify the microangiopathic process. Intrinsic abnormalities of the complement system and of the von Willebrand factor pathway may account for a genetic predisposition to the

    Fetal/neonatal alloimmune thrombocytopenia (FNAIT) is a relatively rare condition (1/1000-1/2000) that was granted orphan status by the European Medicines Agency in 2011. Clinical consequences of FNAIT, however, may be severe. A thrombocytopenic fetus or new-born is at risk of intracranial hemorrhage that may result in lifelong disability or death. Preventing such bleeding is thus vital and requires a solution. Anti-HPA1a antibodies are the most frequent cause of FNAIT in Caucasians. Its pathogenesis is similar to hemolytic disease of the newborn (HDN) due to anti-RhD antibodies, but is characterized by platelet destruction and is more often observed in the first pregnancy. In 75 % of these women, alloimmunization by HPA-1a antigens, however, occurs at delivery, which enables development of antibody-mediated immune suppression to prevent maternal immunization. As for HDN, the recurrence rate of FNAIT is high. For advancing diagnostic efforts and treatment, it is thereby crucial to understand the pathogenesis of FNAIT, including cellular immunity involvement. This review presents the current knowledge on FNAIT. Also described is a program for HPA-1a screening in identifying HPA-1a negative pregnant women at risk of immunization. This program is now performed at the Institute of Hematology and Transfusion Medicine in cooperation with the Department of Obstetrics and Gynecology of the Medical Centre of Postgraduate Education in Warsaw as well as the UiT The Arctic University of Norway.

    Full Text Available A púrpura trombocitopênica trombótica (PTT é uma doença rara e fatal que deve ser diagnosticada e tratada prontamente a fim de se obter melhor resposta terapêutica. Apresentamos um caso de PTT aguda grave tratada com plasmaférese e rituximabe. Ao diagnóstico, a paciente apresentava anemia hemolítica microangiopática, icterícia, febre, convulsões, seguidas por coma e choque hipovolêmico. Os exames laboratoriais iniciais mostravam DHL=2.860 IU/L, contagem de plaquetas de 37 x 10(9/L, hemoglobina de 5,1 g/dL e no esfregaço de sangue periférico havia a presença de esquizócitos. Iniciado tratamento para PTT com pulsoterapia com metilprednisolona e plasmaféreses terapêuticas diárias com troca de uma volemia plasmática e substituição com plasma fresco congelado. Após cinco sessões de plasmaférese, houve piora no quadro neurológico, acompanhado por aumento importante de DHL, ALT, AST e a contagem de plaquetas era de 72 x 10(9/L. Iniciamos o uso de rituximabe na dose padrão de 375mg/m²/semana/4 semanas e passamos a utilizar plasma pobre em crioprecipitado como reposição durante as plasmaféreses. Dois dias após a mudança na conduta terapêutica, houve importante melhora do quadro neurológico, estabilização da contagem de plaquetas e queda acentuada de DHL. Após 23 procedimentos de plasmaférese e quatro doses de rituximabe, a paciente apresentou remissão completa, mantida há 34 meses. A plasmaférese terapêutica com plasma pobre em crioprecipitado e o uso concomitante de rituximabe foi uma estratégia útil no tratamento deste caso de PTT aguda grave. Porém, ensaios clínicos prospectivos e randomizados são necessários para confirmar estes achados.Thrombotic thrombocytopenic purpura (TTP is a rare severe disease that must be diagnosed and treated promptly for a successful outcome.

    2013-01-01

    Full Text Available Posttransfusion purpura (PTP is an uncommon, but potentially fatal, transfusion reaction characterized by profound thrombocytopenia and bleeding. PTP is caused by alloimmunization to human platelet specific antigens following blood component transfusion. Although there is evidence of a wide serological spectrum of culprit antibodies implicated, Anti-human-platelet-antigen- (HPA- 1a is the most common antibody in cases reported. We report a case of posttransfusion purpura in an African American. The patient was negative for HPA-1a antibodies, but anti-HPA-1b was identified with a platelet phenotype of HPA-1a/HPA-1a. Although less common, HPA-1b antibody may be an important consideration in posttransfusion purpura diagnosed in patients of African descent.

    Corneal transplantation is one of the most prevalent and successful forms of solid tissue transplantation. Despite favorable outcomes, immune-mediated graft rejection remains the major cause of corneal allograft failure. Although low-risk graft recipients with uninflamed graft beds enjoy a success rate ∼90%, the rejection rates in inflamed graft beds or high-risk recipients often exceed 50%, despite maximal immune suppression. In this review, we discuss the critical facets of corneal alloimmunity, including immune and angiogenic privilege, mechanisms of allosensitization, cellular and molecular mediators of graft rejection, and allotolerance induction.

    2011-01-01

    Full Text Available Thrombotic thrombocytopenic purpura (TTP is an uncommon life-threatening disease characterized by microangiopathic hemolytic anemia and thrombocytopenia, commonly associated with infections, malignancy, drugs, and autoimmune diseases. We report a case of 19-year-old previously healthy female that presents with anemia and thrombocytopenia diagnosed with thrombotic thrombocytopenic purpura that was treated successfully with plasmapheresis and corticosteroids. Laboratory findings also revealed antinuclear antibodies and antibodies to double-stranded DNA. Two weeks after presentation developed inflammatory arthritis, fulfilling diagnostic criteria for systemic lupus erythematosus (SLE. Prompt diagnosis and treatment with plasma exchange and corticosteroids should be instituted as soon as the diagnosis of TTP is suspected, even if other diagnoses, including lupus, are possible. When present, the coexistence of these two etiologies can have a higher mortality than either disease alone. An underlying diagnosis of SLE should be considered in all patients presenting TTP and the study of this association may provide a better understanding of their immune-mediated pathophysiology.

    Exchange transfusion and phototherapy have traditionally been used to treat jaundice and avoid the associated neurological complications. Because of the risks and burdens of exchange transfusion, intravenous immunoglobulin (IVIg) has been suggested as an alternative therapy for alloimmune hemolytic disease of the newborn (HDN) to reduce the need for exchange transfusion. To assess the effect and complications of IVIg in newborn infants with alloimmune HDN on the need for and number of exchange transfusions. We performed electronic searches of CENTRAL, PubMed, Embase (Ovid), Web of Science, CINAHL (EBSCOhost), Academic Search Premier, and the trial registers ClinicalTrials.gov and controlled-trials.com in May 2017. We also searched reference lists of included and excluded trials and relevant reviews for further relevant studies. We considered all randomized and quasi-randomized controlled trials of IVIg in the treatment of alloimmune HDN. Trials must have used predefined criteria for the use of IVIg and exchange transfusion therapy to be included. We used the standard methods of Cochrane and its Neonatal Review Group. We assessed studies for inclusion and two review authors independently assessed quality and extracted data. We discussed any differences of opinion to reach consensus. We contacted investigators for additional or missing information. We calculated risk ratio (RR), risk difference (RD) and number needed to treat for an additional beneficial outcome (NNTB) for categorical outcomes. We calculated mean difference (MD) for continuous variables. We used GRADE criteria to assess the risk of bias for major outcomes and to summarize the level of evidence. Nine studies with 658 infants fulfilled the inclusion criteria. Term and preterm infants with Rh or ABO (or both) incompatibility were included. The use of exchange transfusion decreased significantly in the immunoglobulin treated group (typical RR 0.35, 95% CI 0.25 to 0.49; typical RD -0.22, 95% CI -0.27 to

  6. A Non-Invasive Strategy for Neonatal Alloimmune Thrombocytopenia Diagnosis: Newborn Platelet Genotyping with Buccal Swabs

    Directory of Open Access Journals (Sweden)

    Gérald Bertrand

    2016-07-01

    Full Text Available Neonatal alloimmune thrombocytopenia results from the maternal immune response against fetal-specific antigens inherited from the father. The diagnosis is ascertained only when the maternal alloantibody and the offending antigen present in the newborn are identified. Up until now most laboratories perform DNA extraction for neonatal genotyping from newborn blood samplings. In order to avoid such an invasive procedure, two protocols of DNA extraction from buccal swabs were developed: a manual protocol using the QIAamp mini blood kit (Qiagen, and an automated procedure with the MagNA Pure Compact instrument (Roche. Both EDTA-blood and buccal swabs from thrombocytopenic newborns were genotyped manually (14 samples, automatically (15 samples or both manually and automatically (two samples. Human Platelet Antigen (HPA genotyping was performed using the BeadChip assay (BioArray, Immucor. Concordant genotypings were obtained for all samples except for one swab with the manual method. The automated DNA extraction from newborn buccal swabs with the MagNA Pure Compact instrument was chosen as the first-line strategy, with a significant gain of time in processing buccal swabs.

    Vasculitis causing palpable purpura, nephropathy, and hematologic abnormalities is a well-known entity. However, sometimes, vasculitis may not be the primary cause but is part of a systemic disease. Literature suggests that infections like HIV can induce nephropathy and antineutrophilic cytoplasmic antibody-positive vasculitis, which is different from the well-known entity of "antineutrophilic cytoplasmic antibody-associated vasculitis." We present a 46-year-old female patient with a history of intravenous drug abuse who reported with a rash, swelling, and palpable purpura of the lower extremities. Peripheral smear showed no evidence of disseminated intravascular coagulation or thrombotic thrombocytopenic purpura; metabolic profile showed acute kidney injury. She was found to be HIV- and hepatitis C-positive. Immunologic workup was positive for both MPO and PR3 antineutrophilic cytoplasmic antibodies and negative for cryoglobulins; complement levels were low. Skin biopsy showed leukocytoclastic vasculitis but kidney biopsy was negative for any immunologic involvement; it showed only glomerulosclerosis. Thus, it was thought that nephropathy and vasculitis, in this case, are two distinct pathologic processes, both induced by infection (HIV and/or hepatitis C). The patient responded to low-dose steroid therapy. She was later started on the definitive therapy, the highly active antiretroviral therapy regimen. This case illustrates the fact that low-dose steroids can still be a good alternative in acute situations in patients at risk from immunosuppression.

    Full Text Available Thrombotic thrombocytopenic purpura (TTP is a rare blood disorder with an estimated incidence of 4–5 cases per million people per year. It is characterized by small-vessel platelet-rich thrombi that cause thrombocytopenia, microangiopathic hemolytic anemia and organ damage. There are reports in literature that TTP and acute pancreatitis are associated, indicating each can be the cause of the other. However, acute pancreatitis triggering TTP is very rare. A 71 years old female presented with abdominal pain of 3 days, followed by dark urine. She had icteric sclera, petechial rash and mild epigastric tenderness. Lab findings were significant for hemolytic anemia, thrombocytopenia and elevated lipase. CT of abdomen showed evidence of pancreatitis and cholelithiasis. After admission, patient developed symptoms of stroke. Further investigation showed elevated lactate dehydrogenase and normal coagulation studied with peripheral blood smear showed 5–6 schistocytes/high power field. Disintegrin and metalloproteinase with thrombospondin motifs-13 (ADAMTS13 activity showed less than 3% with high ADAMTS13 inhibitor 2.2. Patient required 6–7 weeks of daily plasmapheresis until she showed complete response. Our patient presented with clinical features of pancreatitis prior to having dark urine and petechial rash. Therefore, we strongly believe that our patient had pancreatitis which was followed by TTP. Patient's ADMTS13 activity was 6% after 10 plasma exchanges, signifying refractory TTP and higher risk for morbidity and mortality. There are limited data and consensus on the management of refractory TTP. TTP and acute pancreatitis are associated. However, refractory TTP following acute pancreatitis is rarely mentioned in the literature. We would like to emphasize the importance of having higher clinical suspicion of the association of both disease entities.

    Full Text Available Aloimunização é a formação de anticorpos quando há a exposição do indivíduo a antígenos não próprios, como ocorre, por exemplo, na transfusão de sangue incompatível e nas gestantes, cujos fetos expressam em suas células sanguíneas antígenos exclusivamente de origem paterna. Este artigo se restringe à aloimunização contra antígenos eritrocitários em pacientes obstétricas. Quase todos os anticorpos antieritrocitários podem ser enquadrados em um dos 29 sistemas de grupos sanguíneos já reconhecidos, sendo os mais comumente implicados na doença hemolítica perinatal o anti-D, anti-c e anti-Kell, seguidos por anti-C, anti-E, anti e, anti-Fyª e anti-Jkª. A pesquisa de anticorpos irregulares permite o diagnóstico de indivíduos aloimunizados e modernas técnicas genéticas têm melhor caracterizado estas pacientes para a profilaxia e segmento pré-natal. O tradicional acompanhamento das gestações de risco para a doença hemolítica perinatal, com a espectrofotometria do líquido amniótico e a transfusão intraperitoneal, vem rapidamente sendo substituído pela doplervelocimetria na artéria cerebral média e a transfusão intravascular guiada por ultrassonografia em tempo real. É possível também citar como avanços melhorias nos materiais e na qualidade do sangue transfundido, que, em conjunto, têm elevado a sobrevivência de fetos acometidos. Indubitavelmente, a correta aplicação da profilaxia com uso do anti-D é exitosa com potencial para reduzir os casos de aloimunização.Alloimmunization is the formation of antibodies when there is an exposition of the individual to non-self antigens, as it occurs, for example, in the transfusion of incompatible blood and pregnancies, in whom the fetus express in its sanguineous cells antigens exclusively of paternal origin.

    1992-01-01

    A total of 126 patients with chronic idiopathic thrombocytopenic purpura were diagnosed from January 1980 to January 1990 in our institute. In this group of patients, 21 were refractory to prednisone therapy, splenectomy or both, or had had a relapse after a good response with these treatments. They were given other therapies. There was enough information for evaluation in 16 of the 21 patients. The treatment responses were classified according to the post-therapy platelet counts: complete response (CR) = > 150 x 10(9)/L for more than three months; partial response (PR) = 50-150 x 10(9)/L for more than three months; any response (AR) = CR + PR; no response (NR) = < 50 x 10(9)/L. There were 15 women and one male. The median age was 41 years (range 11 to 65). 6-mercaptopurine was given in all patients with CR = 31.2%, PR = 18.8%, AR = 50% and NR = 50%. Seven patients received cyclophosphamide with CR = 28.6%, PR = 14.3%, AR = 42.9% and NR = 57%. Vincristine was given in four patients with only one PR. Interferon alpha 2B was given in four patients with two transitory PR. One patient received colchicine and vitamin C without response. It is concluded that 6-mercaptopurine and cyclophosphamide are useful drugs in refractory thrombocytopenic purpura.

    2017-08-01

    Advances in the prevention and treatment of Rh D alloimmunization have been one of the great success stories of modern obstetrics. There is wide variation in prevalence rates of Rh D-negative individuals between regions, for example from 5% in India to 15% in North America (1). However, high birth rates in low prevalence areas means Rh hemolytic disease of the newborn is still an important cause of morbidity and mortality in countries without prophylaxis programs (1). In such countries, 14% of affected fetuses are stillborn and one half of live born infants suffer neonatal death or brain injury (1). The routine use of Rh D immune globulin is responsible for the reduced rate of red cell alloimmunization in more economically developed countries. First introduced in the 1970s, the postpartum administration of Rh D immune globulin reduced the rate of alloimmunization in at-risk pregnancies from approximately 13-16% to approximately 0.5-1.8% (2, 3). The risk was further reduced to 0.14-0.2% with the addition of routine antepartum administration (2, 3). Despite considerable proof of efficacy, there are still a large number of cases of Rh D alloimmunization because of failure to follow established protocols. In addition, there are new data to help guide management, especially with regard to weak D phenotype women.

    Advances in the prevention and treatment of Rh D alloimmunization have been one of the great success stories of modern obstetrics. There is wide variation in prevalence rates of Rh D-negative individuals between regions, for example from 5% in India to 15% in North America (1). However, high birth rates in low prevalence areas means Rh hemolytic disease of the newborn is still an important cause of morbidity and mortality in countries without prophylaxis programs (1). In such countries, 14% of affected fetuses are stillborn and one half of live born infants suffer neonatal death or brain injury (1). The routine use of Rh D immune globulin is responsible for the reduced rate of red cell alloimmunization in more economically developed countries. First introduced in the 1970s, the postpartum administration of Rh D immune globulin reduced the rate of alloimmunization in at-risk pregnancies from approximately 13-16% to approximately 0.5-1.8% (2, 3). The risk was further reduced to 0.14-0.2% with the addition of routine antepartum administration (2, 3). Despite considerable proof of efficacy, there are still a large number of cases of Rh D alloimmunization because of failure to follow established protocols. In addition, there are new data to help guide management, especially with regard to weak D phenotype women. The purpose of this document is to provide evidence-based guidance for the management of patients at risk of Rh D alloimmunization.

  15. Prostanoids modulate inflammation and alloimmune responses during graft rejection

    Full Text Available Acute rejection of a transplanted organ is characterized by intense inflammation within the graft. Yet, for many years transplant researchers have overlooked the role of classic mediators of inflammation such as prostaglandins and thromboxane (prostanoids in alloimmune responses. It has been demonstrated that local production of prostanoids within the allograft is increased during an episode of acute rejection and that these molecules are able to interfere with graft function by modulating vascular tone, capillary permeability, and platelet aggregation. Experimental data also suggest that prostanoids may participate in alloimmune responses by directly modulating T lymphocyte and antigen-presenting cell function. In the present paper, we provide a brief overview of the alloimmune response, of prostanoid biology, and discuss the available evidence for the role of prostaglandin E2 and thromboxane A2 in graft rejection.

    A 28-year-old woman with primarily therapy refractory TTP was followed neuroradiologically over 6 months. Despite pronounced neurological and neuropsychiatric symptoms including hemiparesis and aphasia she had unremarkable CT scans on two occasions. Three MRI exams showed no correlate for her neurological symptoms except a small petechial cortical hemorrhage in the right parietooccipital gyrus which may account for her TTP-related anxiety disorder. A cerebral HMPAO-SPECT showed long-standing right-sided hypoperfusion compatible with residual vasculature changes. The possible causes for the clinico-neuroradiological discrepancies are discussed in view of the literature.

    Animal bites are typically harmless, but in rare cases infections introduced by such bites can be fatal. Capnocytophaga canimorsus, found in the normal oral flora of dogs, has the potential to cause conditions ranging from minor cellulitis to fatal sepsis. The tendency of C. canimorsus infections to present with varied symptoms, the organism's fastidious nature, and difficulty of culturing make this a challenging diagnosis. Rarely, bacterial cytotoxins such as those produced by C. canimorsus may act as causative agents of TTP, further complicating the diagnosis. Early recognition is crucial for survival, and the variability of presentation must be appreciated. We present the first known case of C. canimorsus infection resulting in TTP that initially presented as splenic infarction. 72-year-old Caucasian male presented with a four-day history of abdominal pain, nausea, vomiting, diarrhea, and intermittent confusion. On presentation, vital signs were stable and the patient was afebrile. Physical examination was unremarkable apart from petechiae on the inner left thigh, and extreme diffuse abdominal pain to palpation and percussion along with positive rebound tenderness. Initial investigations revealed leukocytosis with left shift and thrombocytopenia, but normal liver enzymes, cardiac enzymes, lipase, INR and PTT. Abdominal CT demonstrated a non-enhancing spleen and hemoperitoneum, suggesting complete splenic infarction. Although the patient remained afebrile, he continued deteriorating over the next two days with worsening thrombocytopenia. After becoming febrile, he developed microangiopathic hemolytic anemia and hemodynamic instability, and soon after was intubated due to hypoxic respiratory failure and decreased consciousness. Plasma exchange was initiated but subsequently stopped when positive blood cultures grew a gram-negative organism. The patient progressively improved following therapy with piperacillin-tazobactam, which was switched to imipenem, then meropenem when Capnocytophaga was identified. There is a common misconception amongst practitioners that the presence of systemic infection excludes the possibility of TTP and vice versa. This case emphasizes that TTP may occur secondary to a systemic infection, thereby allowing the two processes to coexist. It is important to maintain a wide differential when considering the diagnosis of either TTP or C. canimorsus infection since delays in treatment may have fatal consequences.

    1981-01-01

    51 Cr-platelet kinetics study was performed in 197 patients with chronic ITP after corticosteroid therapy had failed to induce a long lasting remission. The incidence of splenic, spleno-hepatic, hepatic and diffuse platelet sequestration site was 58%, 17%, 6% and 19%, respectively. Splenic and spleno-hepatic sequestration sites were more frequent in patients less than 30 years old and in patients with a platelet count lower than 50 x 10 9 /l. 111 patients were splenectomized shortly after the study. Normalization of the platelet count was obtained more frequently in patients with splenic and spleno-hepatic sequestration than in the others. Labelled platelet sequestration site was the best predictor of the outcome of splenectomy. Platelet kinetics is a non-invasive investigation that should be performed early after the diagnosis of chronic ITP in all patients eligible for splenectomy. (author)

  4. Is automated platelet counting still a problem in thrombocytopenic blood?

    Full Text Available CONTEXT: Reliable platelet counting is crucial for indicating prophylactic platelet transfusion in thrombocytopenic patients. OBJECTIVE: To evaluate the precision and accuracy of platelet counting for thrombocytopenic patients, using four different automated counters in comparison with the Brecher & Cronkite reference method recommended by the International Committee for Standardization in Hematology (ICSH. TYPE OF STUDY: Automated platelet counting assessment in thrombocytopenic patients. SETTING: Hematology Laboratory, Hospital do Servidor Público Estadual de São Paulo, and the Hematology Division of Instituto Adolfo Lutz, São Paulo, SP, Brazil. MAIN MEASUREMENTS: Brecher & Cronkite reference method and four different automated platelet counters. PARTICIPANTS: 43 thrombocytopenic patients with platelet counts of less than 30,000/µl RESULTS: The ADVIA-120 (Bayer, Coulter STKS, H1 System (Technicom-Bayer and Coulter T-890 automatic instruments presented great precision and accuracy in relation to laboratory thrombocytopenic samples obtained by diluting blood from normal donors. However, when thrombocytopenic patients were investigated, all the counters except ADVIA (which is based on volume and refraction index showed low accuracy when compared to the Brecher & Cronkite reference method (ICSH. The ADVIA counter showed high correlation (r = 0.947. However, all counters showed flags in thrombocytopenic samples. CONCLUSION: The Brecher & Cronkite reference method should always be indicated in thrombocytopenic patients for platelet counts below 30,000 plt /µl obtained in one dimensional counters.

    For many physicians, palpable purpura is synonymous with vasculitis. However, a skin biopsy is almost always performed in common clinical practice in order to confirm the diagnosis. The aim of our study was to assess whether palpable purpura is always indicative of an inflammatory infiltrate in a vessel wall. Eighty-seven patients were included in this prospective monocentric study, 45 of whom were presenting a palpable purpura. Patients were classified in two categories: "leukocytoclastic vasculitis" or "other diagnosis". The clinical and histopathological features of patients with a palpable purpura were studied. The mean age of patients presenting a palpable purpura was 69 years. There were 26 men and 19 women. Of the 43 patients biopsied, 37 were included in the vasculitis group. The sensitivity, specificity, positive predictive value and negative predictive value for a diagnosis of vasculitis in patients with palpable purpura were respectively 82, 65, 86 and 58 %. The Odds ratio was 8.48 (95 % CI, 2.52-31.80; Ppurpuras examined were indeed related to leukocytoclastic vasculitis. In the remaining cases, biopsy did not contribute to the diagnosis since it only showed purpura without vessel wall inflammation. In our opinion, a skin biopsy is thus not essential where the clinical presentation is typical. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    In Caucasians, fetal/neonatal alloimmune thrombocytopenia (FNAIT) is most frequently caused by maternal alloimmunization against the human platelet antigen HPA-1a. The most serious complication of severe FNAIT is intracranial hemorrhage (ICH). ICH mainly occurs in utero; therefore, there is a need to identify noninvasive predictive factors of ICH to facilitate early identification of this condition and to determine response to maternal therapy. We studied gynecologic and immunogenetic variables of severe cases of anti-HPA-1a FNAIT within three groups: Group I, FNAIT without ICH; Group II, FNAIT with ICH; and Group III, suspected FNAIT cases without detectable maternal anti-HPA-1a alloantibodies. ICH was associated with a poor outcome because it led to death in 59% of cases. Multigravida (two or more pregnancies) was overrepresented in Group II, consistent with the high concentrations of maternal HPA-1a alloantibody and the frequent detection of a strong newborn-specific HLA class I antibody response at delivery. The proportion of HLA-DRB4*01:01P (*01:01 or *01:03) women was similar in Groups I and II, but this allele was overrepresented in Group III, in which FNAIT was less severe than in the other two groups. Finally, antenatal intravenous immunoglobulin therapy tended to be more effective in HLA-DRB3*01:01(+)/HLA-DRB4*01:01P(+) women than for HLA-DRB3*01:01(+)/HLA-DRB4*01:01P(-) women. The number of gestations is a predictive factor of ICH in anti-HPA-1a-alloimmunized women. Maternal immunogenetic variables should be investigated in the context of maternal immunization and may predict response to maternal therapy in subsequent pregnancies. © 2015 AABB.

    Foetal/neonatal alloimmune thrombocytopenia is the most common cause of severe thrombocytopenia in the newborn. It is an acute disorder which implies that foetal platelets are destroyed during the pregnancy due to a maternal alloimmune IgG antibody. More than 80% of Caucasians are HPA-1a specific. Intracranial haemorrhage, which occurs in 30% of cases, is the most serious complication, with a 10% mortality rate or a 20% rate of irreversible neurological sequels. The high risk of a recurrence of serious bleeding in future pregnancies led us to consider prophylaxis or prenatal treatment. An early diagnosis of this process allows an effective therapy to be carried out based on the infusion of compatible phenotype HPA platelets or endovenous immunoglobulins. We present the case of a 27 year old pregnant woman, who in the 35th week of a second pregnancy was diagnosed using echography with a bilateral foetal hydrocephaly. After caesarean delivery in the 36th week, the newborn presented haematomas in the left shoulder and gluteus, macrocephalia with tension of the fontanellas and hemorrhagic cerebrospinal fluid after insertion of an external ventricular derivation catheter. The haemogram revealed a severe trombocytopenia (9 x 109/L). In the light of clinical suspicion of foetal/neonatal alloimmune thrombocytopenia, infusion was made of platelets from a non-phenotyped donor for the HPA-1a system, and an endovenous immunoglobulin treatment was followed, with a recovery of platelet counts, but with neurological sequels that are probably irreversible. The immunohaematologal study confirmed the negative HPA-1a maternal phenotype, the neonatal HPA-1a positive phenotype and the presence of anti-HPA-1a alloantibodies in the maternal serum. Nowadays, the prophylaxis and treatment continue to be a controversial issue that is open to discussion, as is the possibility of implementing antenatal screening.

    A quantitative immunofluorescence platelet-associated immunoglobulin-G (PA-IgG) assay was used to detect alloimmunity to platelets in 8/12 multitransfused patients and to perform platelet crossmatching in the 8 alloimmunized patients. The correct separation of multitransfused patients into alloimmune and nonalloimmune groups was substantiated with chromium-51-labeled platelet survival studies. For 5 alloimmunized patients, compatible and incompatible donor platelets were demonstrated by PA-IgG crossmatching and were confirmed by platelet survival studies. With the other 3 alloimmunized patients, only Pa-IgG incompatible donor platelets were found. Survival studies with 5 of these incompatible donor platelets showed markedly reduced survival times on 4 occasions. Pa-IgG compatible donor platelets survived 3.5 to 8.7 days, while Pa-IgG incompatible platelets showed survival times of 0.1 to 2.4 days

    Psychogenic purpura, also known as Gardner-Diamond syndrome or autoerythrocyte sensitization syndrome, is a rare condition characterized by spontaneous development of painful edematous skin lesions progressing to ecchymosis over the next 24 hours. Severe stress and emotional trauma always precede the skin lesions. The condition is most commonly seen in women, but isolated cases have been reported in adolescents and in males. Psychodermatologic evaluation and dermatology and psychiatry liaison have been successful in the treatment of these patients. This report provides an overview of psychogenic purpura and presents the case of a 15-year-old girl. PMID:26137346

    Results: Of 216 SCD patients included in the study. Alloimmunization was detected in 67 (31.0% out of 216 patients who underwent transfusion, and in 17 (30.4% out of 56 patients in Group 1 and in 50 (31.3% out of 160 patients in Group 2. When the patients were analyzed according to alloimmunization development, our study revealed that neither SCD complications are a risk factor for alloimmunization nor alloimmunization increases mortality rates. Conclusion: High alloimmunization frequency found in our study suggests the insufficient adherence of alloimmunization-prevention policies in RBC transfusions performed except experienced institutions. Therefore alloimmunization may be reduced or prevented through performing extended red cell typing among SCD patients. [Cukurova Med J 2016; 41(4.000: 622-627

    2012-01-01

    Full Text Available This article briefly describes our own experience with the proven demonstration of heat shock protein 70 in reperfused renal allografts from brain-deaddonors and reflects about its potential role as a typical damage-associated molecular pattern (DAMP in the setting of innate alloimmunity. In fact, our group was able to demonstrate a dramatic up-regulation of heat shock protein 70 expression after postischemic reperfusion of renal allografts. Of note, up-regulation of this stress protein expression, although to a lesser extent, was already observed after cold storage of the organ indicating that this molecule is already induced in the stressed organism of a brain-dead donor. However, whether or not the dramatic up-regulation of heat shock protein 70 expression contributes to mounting an innate alloimmune response cannot be judged in view of these clinical findings.Nevertheless, heat shock protein 70, since generated in association with postischemic reperfusion-induced allograft injury, can be called a typical DAMP - as can everymolecule be termed a DAMP that is generated in associationwith any stressful tissue injury regardless of its final positive or negative regulatory function within the innate immune response elicited by it.In fact, as we discuss in this article, the context-dependent, even contradistinctive activities of heat shock protein 70 reflect the biological phenomenon that, throughout evolution, mammals have developed an elaborate network of positive and negative regulatory mechanisms, which provide balance between defensive and protective measures against unwarranted destruction of the host. In this sense, up-regulated expression of heat shock protein 70 in an injured allograft might reflect a pure protective response against the severe oxidative injury of a reperfused donor organ. On the other hand, up-regulated expression of this stress protein in an injured allograft might reflect a(futile attempt of the innate immune system to

    β-Thalassemia major (BTM) is considered the most common hemoglobinopathy in Egypt and is one of the major health problems in our locality. We investigated the frequency of B-regulatory cells (CD19(+)CD38(hi)CD24(hi)); (Bregs) among polytransfused alloimmunized and non-alloimmunized children with BTM. The study included 110 polytransfused pediatric patients with β-thalassemia major. Clinical and transfusion records of all studied patients were reviewed. Indirect antiglobulin test was performed to detect the presence of alloantibodies. We used flow cytometry for detection of CD19(+)CD38(hi)CD24(hi) regulatory B cells. Alloimmunization was detected in 35.5% of thalassemic patients (39/110). The analysis of our data showed a significantly higher frequency of Bregs (CD19(+)CD38(hi)CD24(hi)) in the peripheral blood of both alloimmunized and non-alloimmunized patients as compared to healthy controls. Our data showed that the frequencies of CD19(+)CD24(hi)CD38(hi) Bregs cells were significantly increased in children with BTM. Our data suggested that Bregs cells could play a role in the clinical course of BTM. The relationship of Bregs to immune disorders in BTM children remains to be determined. Further longitudinal study with a larger sample size is warranted to explore the mechanisms of Breg cells in the disease process in BTM patients. Copyright © 2016 Elsevier Inc. All rights reserved.

    Some studies suggest that thrombotic thrombocytopenic purpura (TTP) occurs more often in African Americans. However there is low evidence for this in the literature. The aim of our study was to describe the clinical and biological characteristics of TTP in the Afro-Caribbean population of Martinique. We retrospectively analysed all patients with TTP diagnosed at the Fort-de-France hospital between 2008, January 1st and 2015, December 31st. Diagnosis was confirmed if ADAMTS-13 activity was<10 %. Ten patients were included, corresponding to an average annual incidence of 3.2 cases/year/million individuals. None of the patient presented with the association of the five characteristic features of TTP. Microangiopathic haemolytic anaemia and severe peripheral thrombocytopenia (median: 13G/L) was the main presentation leading to diagnosis. There was no kidney involvement in 90 % of all patients, but severe neurological manifestations occurred in 70 %. Classical management including corticosteroids and plasma exchanges allowed clinical remission in 6 out of the 10 cases. If necessary, rituximab or cyclophosphamide was used. The overall survival rate was 90 %. In Martinique, the incidence of TTP is twice that reported in similar studies in France. Clinical manifestations seem to differ by more common and more severe neurological involvement. Mortality is low, in part, due to optimal care.

    Idiopatic thrombocytopenic purpura (ITP) is the most common indication for splenectomy. The failure rate of surgery is about 8% and the failure rate after splenectomy is approximately 28% for all patients. When the presence of an accessory spleen is diagnosed, splenectomy is recommended. Laparoscopic approach is considered the first choice. At our Department, between July and November 2011 two patients underwent laparoscopic accessory splenectomy for recurrence of ITP. Both patients had a previously laparoscopic splenectomy. Preoperative Magnetic Resonance (MR) was performed in both the cases revealing the presence of an accessory spleen. The operative time was 105 and 100 minutes respectively. No perioperative complications occured. Hospital stay was four days in both cases. The first patient had a disease free period of two months; the second one of one month. Both patients restarted immunosuppressive therapy. The relapse of thrombocytopenia post-splenectomy can be associated with the presence of an accessory spleen. The laparoscopic accessory splenectomy should be considered the first choice approach. Surgical accessory splenectomy allows a transitory remission of the disease.

Maternal characteristics, antibody type, antibody titer in addition to perinatal and neonatal outcomes were reviewed. Results: There were 1160 patients with Rh positive status in the study. The most common ABO blood group was O, followed by A, B, and AB. We found 33 out of 1160 Rh positive women alloimmunized with minor RBCs antibodies that gave a prevalence of minor RBCs alloimmunization of 2.7%. The most frequent antibody was anti-E 38%, followed by anti-c 17% and anti-kell 17%. 6 of these 33 patients were identified to have significant antibody titer, and two cases showed evidence of fetal anemia. Only one case required an intrauterine blood transfusion. The most common neonatal complication was jaundice in 53%, followed by respiratory distress syndrome in 28%. Two cases complicated by neonatal anemia required a postnatal blood transfusion. Conclusion: Alloimmunization with anti-E, anti-c, and anti-kell were the most common antibodies among the study group. Minor RBCs alloimmunization was an important cause of neonatal morbidity.

  19. The Nlrp3 Inflammasome Does Not Regulate Alloimmunization to Transfused Red Blood Cells in Mice

    Full Text Available Red blood cell (RBC transfusions are essential for patients with hematological disorders and bone marrow failure syndromes. Despite ABO matching, RBC transfusions can lead to production of alloantibodies against “minor” blood group antigens. Non-ABO alloimmunization is a leading cause of transfusion-associated mortality in the U.S. Despite its clinical importance, little is known about the immunological factors that promote alloimmunization. Prior studies indicate that inflammatory conditions place patients at higher risk for alloimmunization. Additionally, co-exposure to pro-inflammatory pathogen associated molecular patterns (PAMPs promotes alloimmunization in animal models, suggesting that RBC alloimmunization depends on innate immune cell activation. However, the specific innate immune stimuli and sensors that induce a T cell-dependent alloantibody response to transfused RBCs have not been identified. The NLRP3 inflammasome senses chemically diverse PAMPs and damage associated molecular patterns (DAMPs, including extracellular ATP and iron-containing heme. We hypothesized that activation of the NLRP3 inflammasome by endogenous DAMPs from RBCs promotes the alloimmune response to a sterile RBC transfusion. Using genetically modified mice lacking either NLRP3 or multiple downstream inflammasome response elements, we ruled out a role for the NLRP3 inflammasome or any Caspase-1 or -11 dependent inflammasome in regulating RBC alloantibody production to a model antigen.

    Erlotinib is an epidermal growth factor receptor (EGFR) inhibitor, used as a treatment for advanced stage cancer. The most common side effect is cutaneous toxicity including the already known papulopustular reaction. We herein report a case of erlotinib induced target-like purpura, a peculiar cutaneous adverse event. A 57-year-old patient with advanced non-small cell lung cancer was treated by erolotinib 150 mg daily. After taking the drug for three days, an unusual target-like purpura developed on her lower legs. Skin biopsy specimen taken from the lesion revealed an extravasation of erythrocytes in the upper dermis without destruction of blood vessel walls. This skin eruption cleared after the drug was withdrawn and recurred after erlotinib was re-challenged. The mechanism underlying this cutaneous adverse event remains to be elucidated. Physicians should be aware of the rare side effect of this increasingly used drug.

    Full Text Available Background: Serological safety is an integral part of overall safety for blood banks. Emphasis is on the use of routinue Red Blood Cell (RBC antibody screen test, at set time intervals, to reduce risks related to alloantibodies. Also emphasis is on importance of issuing antigen negative blood to alloantibody positive patients. Effect of using leucodepleted blood on the rate of alloimmunization is highlighted. The concept of provision of phenotypically matched blood is suggested. Materials and Methods: Antibody screen test is important to select appropriate blood for transfusion. Repeat antibody screen testing, except if time interval between the earlier and subsequent transfusion was less than 72 hours, followed by antibody identification, if required, was performed in patients being treated with repeat multiple blood transfusions. Between February 2008 and June 2009, repeat samples of 306 multi-transfused patients were analyzed. Search for irregular antibodies and reading of results was conducted using RBC panels (three-cell panel of Column Agglutination Technology (CAT and two cell panel of the Solid Phase Red Cell Adherence Technology (SPRCAT. Specificities of antibodies were investigated using appropriate panels, 11 cell panel of CAT and 16 cell panel of SPRCA. These technologies, detecting agglutination in columns and reactions in solid phase, evaluate the attachment of irregular incomplete antibody to antigen in the first phase of immunological reaction more directly and hence improve the reading of agglutination. Three to four log leuco reduced red blood cells were transfused to patients in the study using blood collection bags with integral filters. Results: Alloimmunization rate of 4.24% was detected from 306 multiply transfused patients tested and followed up. The Transfusion therapy may become significantly complicated. Conclusion: Red cell antibody screening and identification and subsequent issue of antigen negative blood have a

    The clinical significance of platelet associated IgG in ITP detected by direct platelet suspension immunofluorescence test (PSIFT) was studied. The platelet mean life span (MLS) was measured with 111 In-labelled platelets in 17 adult patients. All the patients had shortened platelet MLS. The direct PSIFT was positive in 14 patients. Patients were initially treated with prednisone; 12 patients with poor response to the drug were splenectomised. 8 of these 12 patients were treated with intravenous immunoglobulin (IvIg) before splenectomy. The response to IvIg was as good or better in the 3 patients with negative PSIFT, than in the 5 patients with positive PSIFT. (author)

    Contrary to the accepted view, the authors have found that platelet turnover is not always increased in ITP if the mean platelet survival time (PS) is measured with In-AP. The authors investigated the possible cause of the discrepancy by comparing kinetics of In-AP with those of Cr-HP in 10 patients with ITP. PS was estimated with the multiple hit model. The equilibrium and final in vivo distribution of In-AP was quantitated with the geometrical mean method. The patients could be divided into either those with splenic or diffuse RES platelet destruction. The authors conclude that in ITP platelet survival of In-AP is significantly (P < .05) longer than that of Cr-HP. Platelet turnover measured with In-AP is only normal in patients with mainly splenic platelet sequestration. Results with Cr-HP give a false impression of PS. It seems that in ITP those patients with severe disease also have a platelet production defect

    Sickle cell disease (SCD) is common in the Arabian Gulf region. Most cases require a red blood cell (RBC) transfusion, increasing the potential for RBC alloantibody development. The incidence of RBC alloimmunization among Kuwaiti Arab SCD patients is not yet known. This study retrospectively assessed the effect of using two different matching protocols on the incidence of alloimmunization among multiply transfused Kuwaiti Arab SCD patients. A total of 233 Kuwaiti Arab SCD patients were divided into two groups: Group 1 (n = 110) received RBC transfusion through standard ABO- and D-matched nonleukoreduced blood; Group 2 (n = 123) received RBCs matched for ABO, Rh, and K1 poststorage-leukoreduced blood. Multivariate analysis was performed on the factors associated with RBC alloimmunization and antibody specificity. Sixty-five percent of patients in Group 1 developed clinically significant RBC alloantibody with an increased prevalence in females; in patients in Group 2, 23.6% developed RBC alloantibodies (p = 0.01). In Group 1, 72 patients (65.5%) had alloantibodies directed against Rh and Kell systems (p = 0.01). Multivariate analysis further confirmed the results, showing that blood transfusion type and sex have significant effects on the rate of alloimmunizations. This study confirms the importance of selecting RBCs matched for Rh and Kell to reduce the risk of alloimmunizations among Kuwaiti Arab SCD patients.

    To analyze the clinical features and SLC25A13 gene mutations of a child with citrin deficiency complicated with purpura, convulsive seizures and methioninemia. The patient was subjected to physical examination and routine laboratory tests. Blood amino acids and acylcarnitines, and urine organic acids and galactose were analyzed respectively with tandem mass spectrometry and gas chromatographic mass spectrometry. SLC25A13 gene mutation screening was conducted by high resolution melt (HRM) analysis. The petechiae on the patient's face and platelet count (27×10(9)/L, reference range 100×10(9)/L-300×10(9)/L) supported the diagnosis of immunologic thrombocytopenic purpura (ITP). Laboratory tests found that the patient have abnormal coagulation, cardiac enzyme, liver function and liver enzymes dysfunction. Tandem mass spectrometry also found methionine to be increased (286 μmol/L, reference ranges 8-35 μmol/L). The patient did not manifest any galactosemia, citrullinemia and tyrosinemia. Analysis of SLC25A13 gene mutation found that the patient has carried IVS16ins3kb, in addition with abnormal HRM result for exon 6. Direct sequencing of exon 6 revealed a novel mutation c.495delA. The same mutation was not detected in 100 unrelated healthy controls. Further analysis of her family has confirmed that the c.495delA mutation has derived from her farther, and that the IVS16ins3kb was derived from her mother. The clinical features and metabolic spectrum of citrin deficiency can be variable. The poor prognosis and severity of clinical symptoms of the patient may be attributed to the novel c.495delA mutation.

    Full Text Available Abstract Introduction Henoch-Schönlein purpura is a common immunoglobulin A-mediated vasculitis syndrome in children. Henoch-Schönlein purpura can also affect adults and is probably related to malignancy. Case presentation We report the case of a 61-year-old Japanese man who presented for examination after an abnormal shadow was detected by chest radiography. He received a diagnosis of pulmonary adenocarcinoma, stage IV. Purpura on the legs, abdominal pain, diarrhea, hematuria and proteinuria developed at this time. Henoch-Schönlein purpura was diagnosed, base on the clinical symptoms and histological findings of biopsy specimens of the skin, which showed vasculitis with immunoglobulin A deposits. Our patient received chemotherapy with gemcitabine after successful steroid therapy for the Henoch-Schönlein purpura. Conclusion Although hematological malignancies are well-known causes of vasculitides, cases of Henoch-Schönlein purpura associated with lung adenocarcinoma are rare. Our patient was treated with corticosteroid therapy, which cleared the purpura and cytotoxic chemotherapy for the non-small cell lung cancer. However, he died from heart failure due to cardiac tamponade.

    Etiology of cholestatic liver disease in neonates with hemolytic disease of the newborn (HDN) has been associated with iron overload due to intrauterine red cell transfusions (IUTs). Data on the incidence and severity of cholestasis in neonates with HDN are scarce, and little is known about pathogenesis, risk factors, neonatal management and outcome. To evaluate incidence, risk factors, management and outcome of cholestasis in neonates with red cell alloimmune hemolytic disease. All (near-) term neonates with HDN due to red cell alloimmunization admitted to our center between January 2000 and July 2010 were included in this observational study. Liver function tests (including conjugated bilirubin) were routinely performed in the neonatal period. We recorded the presence of cholestasis, investigated several potential risk factors and evaluated the management and outcome in affected neonates. A total of 313 infants with red cell alloimmune hemolytic disease treated with or without IUTs were included. The incidence of cholestasis was 13% (41/313). Two risk factors were independently associated with cholestasis: treatment with at least one IUT (OR 5.81, 95% CI 1.70-19.80, p = 0.005) and rhesus D type of alloimmunization (OR 4.66, 95% CI 1.05-20.57, p = 0.042). Additional diagnostic tests to investigate possible causes of cholestasis were all negative. In 5 infants (12%), supportive medical and nutritional therapy was started, and one neonate required iron chelation therapy. Cholestasis occurs in 13% of neonates with HDN due to red cell alloimmunization, and it is independently associated with IUT treatment and rhesus D type of alloimmunization. Copyright © 2012 S.

    Enzyme indirect antiglobulin test (EIAT) and polyethylene glycol IAT (PIAT) were evaluated for their potential use as tests to distinguish between prophylactic and alloimmune anti-D in plasma by comparing with a tube variation of the standard low ionic strength solution-IAT (LISS-IAT). Laboratories performing the screening of RhD-negative pregnant women are required to provide clinicians with guidance as to the source of detected RhD antibodies. Currently, this is derived from RhIg immunoprophylaxis history, agglutination scores and titration results, where performed. A serological test that can differentiate between prophylactic and alloimmune anti-D would be useful in the diagnosis of RhD alloimmunisation in pregnant women. Plasma samples (n = 273) [fresh (collected from April 2014 to February 2015) and frozen (up to 2 years)] from antenatal females, preoperative males and females over child-bearing age were used in this study. Samples were identified as containing anti-D by routine column agglutination (CAT) and were tested by tube LISS-IAT, EIAT and PIAT, and a score difference was calculated. A total of 32% of alloimmune anti-D samples demonstrated an increase in agglutination score (+2 or +3) when tested by EIAT. A significant increase in agglutination score for alloimmune samples using EIAT compared with LISS-IAT was observed. EIAT had a sensitivity (Sn) of 59%, positive predictive value (PPV) of 100% and specificity (Sp) of 100% for alloimmune anti-D. EIAT is capable of confirming but not excluding the presence of alloimmune anti-D in samples where anti-D is detected in routine antibody screening. © 2017 British Blood Transfusion Society.

    Full Text Available Purpura fulminans (PF is associated with several infections, most notably with meningococcus, staphylococcus, and streptococcus infections. However, there are few reports of association of this entity with spotted fever from India. We report the case of a 55-year-old man who presented with fever, headache, and myalgia. On the seventh day of fever he developed nonblanching purple hemorrhagic purpura on the trunk and most prominently on the extremities consistent with purpura fulminans. Immunofluorescent assay confirmed the diagnosis of spotted fever. PF though common with rocky mountain spotted fever (RMSF is rarely seen in association with Indian tick typhus, the usual cause of spotted fever in India.

    The reported frequency of D alloimmunization in D- recipients after transfusion of D+ platelets varies. This study was designed to determine the frequency of D alloimmunization, previously reported to be an average of 5 ± 2%. A primary anti-D immune response was defined as the detection of anti-D ≥ 28 d following the first D+ platelet transfusion. Data were collected on 485 D- recipients of D+ platelets in 11 centres between 2010 and 2012. Their median age was 60 (range 2-100) years. Diagnoses included: haematological (203/485, 42%), oncological (64/485, 13%) and other diseases (218/485, 45%). Only 7/485 (1·44%; 95% CI 0·58-2·97%) recipients had a primary anti-D response after a median serological follow-up of 77 d (range: 28-2111). There were no statistically significant differences between the primary anti-D formers and the other patients, in terms of gender, age, receipt of immunosuppressive therapy, proportion of patients with haematological/oncological diseases, transfusion of whole blood-derived or apheresis platelets or both, and total number of transfused platelet products. This is the largest study with the longest follow-up of D alloimmunization following D+ platelet transfusion. The low frequency of D alloimmunization should be considered when deciding whether to administer Rh Immune Globulin to D- males and D- females without childbearing potential after transfusion of D+ platelets. © 2014 John Wiley & Sons Ltd.

    2014-12-01

    Incompatibility of red cell and platelet antigens can lead to maternal alloimmunization causing hemolytic disease of the fetus & newborn and fetal neonatal alloimmune thrombocytopenia respectively. As the molecular background of these polymorphisms emerged, prenatal testing using initially fetal DNA obtained from invasively obtained amniotic fluid or chorionic villus was implemented. This evolved into testing using maternal plasma as source of fetal DNA, and this is in routine use as a safe non-invasive diagnostic that has no risk to the fetus of alloimmunization or spontaneous miscarriage. These tests were initially applied to high risk pregnancies, but has been applied on a mass scale, to screen fetuses in D-negative pregnant populations as national screening programs. Fetal neonatal alloimmune thrombocytopenia management has had comparatively small take up in non-invasive testing for causative fetal platelet alleles (e.g., HPA-1A), but mass scale genotyping of mothers to identify at risk HPA-1b1b pregnancies and their treatment with prophylactic anti-HPA-1A is being considered in at least one country (Norway).

    Alloimmunization is an adverse effect of blood transfusions. In Chile, alloimmunization frequency is not established, and for this reason the aim of this study was to investigate the prevalence and specificity of red blood cell (RBC) alloantibodies in Chilean transfused subjects. Records from 4,716 multi-transfused patients were analyzed. In these patients, antibody screening was carried out prior to cross-matching with a commercially available two-cell panel by the microcolum gel test, and samples with a positive screen were analyzed for the specificity of the alloantibody with a 16-cell identification panel. The incidence of RBC alloimmunization in transfused patients was 1.02% (48/4,716) with a higher prevalence in women (40/48). We detected 52 antibodies, the most frequent specificities identified were anti-E (30.8%), anti-K (26.9%), anti-D (7.7%), and anti-Fy(a) (5.8%). The highest incidence of alloantibodies was observed in cancer and gastroenterology patients. The data demonstrated a low alloimmunization frequency in Chilean transfused patients, principally associated with antibodies anti-E, anti-K, anti-D, and anti-Fy(a).

    Prosthetic graft infection after vascular reconstruction is a rare but serious complication. We report a case of infection occurring late after implantation of an iliofemoral prosthetic vascular graft. The Staphylococcus aureus infection was revealed by vascular purpura localized on the right leg 7 years after implantation of a vascular prosthesis. This case illustrates an uncommonly late clinical manifestation presenting as an acute infection 7 years after the primary operation. In this situation, the presentation differs from early infection, which generally occurs within the first four postoperative months. Diagnosis and treatment remain a difficult challenge because prosthetic graft infection is a potentially life-threatening complication. Morbidity and mortality rates are high. Here we detail specific aspects of the clinical and radiological presentation. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Purpura was grossly observable in albino mice 6 to 8 h after the intraperitoneal injection of sterile, deoxyribonuclease-treated, cell-free extracts prepared by sodium deoxycholate-induced lysis, sonic disruption, Parr bomb treatment, autolysis without sodium deoxycholate, or alternate freezing and thawing of washed suspensions of Streptococcus pneumoniae type I. Cell-free extracts obtained from sonically disrupted, heat-killed cells (100 degrees C for 20 min) did not contain purpurogenic activity. The reaction was maximal at approximately 24 h postinjection, started to fade slowly after 24 to 48 h, and usually was not grossly observable by 4 to 6 days postinjection. The purpura-producing principle (PPP) in the cell-free extract was purified by sequential ammonium sulfate precipitation, protamine sulfate precipitation, Sepharose 6B gel filtration, wheat germ lectin-Sepharose 6MB affinity chromatography, ribonuclease and trypsin treatment, and a second Sepharose 6B gel filtration step. The final preparation (i) contained glucosamine (5.6%), muramic acid (8.0%), neutral carbohydrate (12.8%), phosphate (8.0%), orcinol-reactive material (6.0%), and Lowry-reactive material (1.6%), and (ii) was free of detectable amounts of deoxyribonucleic acid, capsular polysaccharide, neuraminidase, cytolysin, and hyaluronidase. The isoelectric point and molecular size of the PPP were approximately pI 3.0 and several million daltons, respectively, and the activity remained in the supernatant fluid after centrifugation for 1 day at 105,000 x g. PPP activity was destroyed by incubation with egg white lysozyme and sodium metaperiodate but was resistant to trypsin, pronase, alpha-amylase, deoxyribonuclease, ribonuclease, alkaline phosphatase, pancreatic lipase, 7% trichloroacetic acid, 6 M urea, autoclaving (121 degrees C) for 30 min, and mild acid and alkali exposure. Our observations indicate that the PPP requires intact beta-1,4-glucosidic linkages for activity and support the working

    Full Text Available Introduction: Thalassemia is one of the most common genetic disorder of hemoglobin synthesis in Jammu region. Although RBC transfusion is life saving for these patients, it may be associated with some complications like RBC alloimmunization. Thus, the aim of this study was to determine the frequency of alloimmunization and the most common alloantibodies involved. Material and Methods: This was a descriptive study involving a total of 70 thalassemic patients in the age range of 2-17 years receiving regular blood transfusions, registered at SMGS Blood Bank, Jammu. Relevant clinical and laboratory data was collected with reference to age at the start of transfusions, total number of transfusions received and splenectomy status. Antibodies screening, antibody identification, and cross matching was done on allpatient samples included in the study, during the period between November 2009 and October 2010. Results: In this study, a total of six alloantibodies six patients (8.5% and one autoantibody (1.42% was detected. All identified alloantibodies belonged to Rh system (i.e. anti-E, in 3 patients (50%, anti D, in one patient (16.66% and Kell system (anti-K, in two patients (33.34%. Higher frequency of alloimmunization was found, with increase in number of transfusions and in those who received transfusions after 1 year of age. Alloimmunization was not significantly associated with gender and splenectomy status (P-value > 0.05. Conclusion: Red cell alloantibodies developed in 8.5% of thalassemic patients and 1.42% had autoantibodies. The most common alloantibodies identified were anti Rh system antibodies (anti-E and anti-D present in 50% and 16.66% of patients respectively. Alloimmunization is not an uncommon problem faced by blood banks and finding compatible units for regularly transfused thalassemic patients may become very difficult. In order to reduce alloimmunization, a policy for performing extended red cell phenotyping of these patients is

    Full Text Available CONTEXT: Patients with antiphospholipid syndrome and alloimmunity have poor pregnancy outcomes. Several diagnostic and therapeutic options exist for these disorders, although there is no consensus as to the best treatment. CASE REPORT: We present here the clinical course and treatment of a woman with a history of two miscarriages who joined our program 10 years ago and has been followed up ever since. After antiphospholipid syndrome and alloimmune failure were diagnosed, she was given preconceptional treatment using unfractionated heparin, aspirin, prednisone and lymphocyte immunizations. She delivered two premature babies in the following two pregnancies. At present both children are healthy and are attending school. The fifth pregnancy was unsuccessful, in spite of having undergone a similar but postconceptional therapeutic scheme.

    Full Text Available We report a case of severe intrauterine hemolysis caused by sole anti-E alloimmunization. A 36-year-old multipara woman presented with hydrops fetalis at 27 weeks of gestation. She had a history of previous neonatal death. In this pregnancy, she was found to have very high titer of anti-E antibody. Ultrasonography detected marked skin edema, cardiomegaly, hepatosplenomegaly, pleural effusion, ascites, placentomegaly, and polyhydramnios. The Doppler peak systolic velocity in the middle cerebral artery was 0.8 m/s, indicating severe fetal anemia. Multiple intrauterine transfusions for the anemic fetus were administered. However, persistent severe fetal anemia and placentomegaly caused poor neonatal death and mirror syndrome in the mother. Uncommon red blood cell alloimmunization has to be watched for early in any population, especially in a woman with a history of unexplained perinatal loss.

    Henoch-Schönlein purpura (HSP) is systemic vasculitis disease with various clinical manifestations. Gastrointestinal symptoms in patients with HSP are usually common, with an incidence rate of 62-90%. Most of these gastrointestinal symptoms occur after typical skin purpura, which is a very important clinical evidence for making a diagnosis of HSP. It is difficult to diagnose HSP without skin rash. About 25% of patients may experience gastrointestinal symptoms as their first symptoms. Herein, we report a case of ileo-colic intussusception associated with HSP in a 5-years-old girl presented with diffuse abdominal distension. Our patient did present any symptoms of HSP, such as purpura, arthralgia or arthritis, before surgery.

    Full Text Available Background: The development of anti-red blood cell antibodies (both allo-and autoantibodies remains a major problem in thalassemia major patients. We studied the frequency of red blood cell (RBC alloimmunization and autoimmunization among thalassemia patients who received regular transfusions at our center and analyzed the factors, which may be responsible for development of these antibodies. Materials and Methods: The study was carried out on 319 multiply transfused patients with β-thalassemia major registered with thalassemia clinic at our institute. Clinical and transfusion records of all the patients were examined for age of patients, age at initiation of transfusion therapy, total number of blood units transfused, transfusion interval, status of splenectomy or other interventions. Alloantibody screening and identification was done using three cell and 11 cell panel (Diapanel, Bio-rad, Switzerland respectively. To detect autoantibodies, autocontrol was carried out using polyspecific coombs (IgG + C3d gel cards. Results: Eighteen patients out of total 319 patients (5.64% developed alloantibodies and 90 (28.2% developed autoantibodies. Nine out of 18 patients with alloantibodies also had autoantibodies. Age at first transfusion was significantly higher in alloimmunized than non-immunized patients (P = 0.042. Out of 23 alloantibodies, 52.17% belonged to Rh blood group system (Anti-E = 17%, Anti D = 13%, Anti-C = 13%, Anti-C w = 9%, 35% belonged to Kell blood group system, 9% of Kidd and 4% of Xg blood group system. Conclusion: Alloimmunization was detected in 5.64% of multitransfused thalassemia patients. Rh and Kell blood group system antibodies accounted for more than 80% of alloantibodies. This study re-emphasizes the need for RBC antigen typing before first transfusion and issue of antigen matched blood (at least for Rh and Kell antigen. Early institution of transfusion therapy after diagnosis is another means of decreasing

    Well infants with petechiae and/or purpura can present to emergency departments, and their management can be difficult. Many will have extensive investigations and treatment that may not be necessary. This was a retrospective and descriptive audit investigating well infants (purpura in the absence of fever to a pediatric emergency department over a 9½-year period. All presenting problems of petechiae or purpura were reviewed. Patients were excluded if they appeared unwell, were febrile or have a history of fever, or had eccyhmoses on presentation. Thirty-six babies were identified. The average age was 3.8 months (range, 1-7 months). The majority of the infants had localized purpura/petechiae to the lower limbs (92%) with two thirds of these patients having bilateral signs. None had generalized signs. Most infants had a full blood count (94%), coagulation profile (59%) and C-reactive protein (59%), and blood cultures (59%), with all being normal (except for mild elevation in platelets). Nine patients were admitted for observation, with only 1 patient having progression of signs. This patient had a diagnosis of acute hemorrhagic edema of infancy. The rest of the patients were thought to have either a mechanical reason for their petechiae/purpura (tourniquet phenomena) or a formal diagnosis was not specified. Well infants with localized purpura and/or petechiae with an absence of fever are more likely to have a benign etiology. Further study is required to determine if a full blood count and coagulation profile is necessary, or a period of observation (4 hours) is all that is required. If there is no progression of signs, it is likely that they can be safely discharged. The likely cause may be due to a tourniquet phenomenon (eg, diaper).

  8. A case of Hydrops fetalis due to Kell alloimmunization: A perinatal approach to a rare case

    2012-03-01

    Full Text Available Introduction: While the routine administration of Rhesus immunoglobulin has significantly reduced the incidence of this type of alloimmunization, maternal alloimmunization to other red cell antigens continues to contribute to perinatal morbidity and mortality. Although the Kell antigen is found on the red cells of only 9% of the population, attention has increasingly been focused on Kell antibodies. Case Report: We present a case of fetal hydrops who was sonographically detected at 30th week of pregnancy. Antenatal tests for evaluation of fetal condition clearly showed the critical level of hemolytic disease but the baby was delivered prematurely due to fetal distress. The combination of anemia, reticulocytopenia, hydrops fetalis, and positive indirect Coombs test suggested Kell isoimmunization. The baby was treated by exchange transfusion with the Kell-negative packed red cell succesfully, and was discharged on postnatal 30th day. Conclusion: Here we describe a case of hydrops fetalis caused by Kell alloimmunization that was determined in postnatal period, and thus we plan to discuss the perinatal approach to the Kell immunization.

    Full Text Available Objectives: The detection of maternal alloimmunization against red cell antigens is vital in the management of hemolytic disease of the fetus and newborn. We sought to measure the presence of allosensitization to Rhesus D (RhD antibodies in antenatal women attending a tertiary care hospital and assess the fetal outcome in sensitized women. Methods: We conducted a retrospective review of pregnant Omani women who registered at the Sultan Qaboos University Hospital between June 2011 and June 2013. Pregnant women were tested for ABO blood type and were screened for RhD antigen and antibodies at their first antenatal clinic visit. In women who tested positive for the RhD antibodies, an antibody titer was performed to evaluate the severity of their case. Results: Data was available on 1,251 pregnant women who were managed and delivered at Sultan Qaboos University Hospital. The prevalence of RhD negative pregnant women was 7.3%. Blood group O was the most common followed by A, B, and AB. The rate of RhD negative alloimmunization was 10%, and anti-D was the most common antibody detected. There were no stillbirths or neonatal deaths. Postnatal transfusion was necessary for only one baby. Conclusions: The prevalence of RhD negativity was comparable to other Asian countries. Previous RhD alloimmunization and history of miscarriages were the most common maternal medical history.

    Although Henoch-Schönlein purpura (HSP) is known to be accompanied by malignancies, cases with hepatobiliary cancer are extremely rare. A 62-year-old man with palpable purpura rapidly extending to both lower legs was admitted to our hospital. He was undergoing follow-up for cirrhosis caused by chronic hepatitis B virus infection and hepatocellular carcinoma (HCC). He had renal dysfunction with hematuria and proteinuria and abdominal pain. Based on the clinical presentation and skin biopsy findings, he was diagnosed with HSP. The administration of steroids resulted in the rapid improvement of the patient's symptoms and he was discharged 12 days after admission.

    Pulmonary manifestations in anaphylactoid purpura (Henoch-Schoenlein-syndrome). Radiological observations are reported on 2 female adults with Henoch-Schoenlein-syndrome accompanied by reversible pulmonary disease. This form of anaphylaktoid purpura has rarely been reported until now. The pulmonary opacities are regarded as intraalveolar bleeding probably with edem and interstitial perivascular infiltrations. They developed at the same time as the skin lesions and are probably part of the disease. These pulmonary changes are characterized by the following radiological criteria: 1. parahilar, butterfly-shaped opacities, 2. air-bronchograms, 3. reticulo-nodular pattern, 4. rapid change. (orig.)

    Kazandjieva, Jana; Antonov, Dimitar; Kamarashev, Jivko; Tsankov, Nikolai

    Purpuric lesions appear in acral distribution in a variety of conditions and often provide clues to the clinical diagnosis. Purpuric means "hemorrhagic"-that is, the lesions do not blanch from pressure. This review focuses on dermatoses that produce hemorrhagic lesions in acral distribution from the large groups of the vasculitic diseases and their mimics. Cutaneous small vessel vasculitis is confined to the skin, involves mainly postcapillary venules, and has the hallmark manifestation of palpable purpura. Henoch-Schönlein purpura is an immune complex-mediated systemic vasculitis of the small vessels with manifestations from the skin, joints, kidneys, and gastrointestinal system. Only cases where the immune complexes contain immunoglobulin A type are classified as Henoch-Schönlein purpura. Cryoglobulinemic vasculitis is induced by the deposition of cold-precipitated immune complexes in the small vessels. Urticarial vasculitis comprises a spectrum of conditions with the characteristic course of chronic urticaria, with wheals that persist longer than 24 hours, leave hyperpigmentation, and have leukocytoclastic vasculitis on histologic examination. Polyarteritis nodosa is a rare multisystem, segmental necrotizing vasculitis of mainly the medium-sized vessels. Pigmented purpuric dermatoses are chronic benign dermatoses characterized by petechiae, purpura, and increased skin pigmentation. The hallmark of pigmented purpuric dermatoses is their orange-brown, speckled, cayenne pepper-like discoloration. Copyright © 2016 Elsevier Inc. All rights reserved.

    The purpose of this study was to describe the ultrasonographic features and assess the diagnostic value of sonography in the evaluation of children with Henoch-Schonlein purpura. Between October 1993, and Febuary 1998, 67 children with Henoch-Schonlein purpura underwent abdominal ultrasonography, which in 13 was used for follow up. Bowel wall thickness and location, pattern of color Doppler signal in the thickened bowel wall, the size and location of enlarged mesenteric lymph node and the presence of ascites were evaluated. In 42 cases(63%), sonographic findings were positive, and indicated mesenteric lymphadenopathy(n=3D21), small bowel wall thickening(n=3D20), and ascites(n=3D17). Thickened bowels were demonstrated at the ileum in 11 cases, the jejunum in five, the duodenum in one, and combined wall thickening at the duodenum and jejunum in two;thickening of the duodenum and ileum was seen in one case. Thickness varied from 3 to 10 mm(mean:6.5 mm). On follow-up sonography, regression of bowel wall thickening was observed earlier than that of mesenteric lymphadenopathy or ascites, and correlated well with improved abdominal symptoms. Abdominal ultrasonographic manifestations of Henoch-Schonlein purpura were bowel wall thickening, mesentric lymphadenopathy and ascites. Sonography was a simple and useful method for the evaluation of gastrointestinal manifestation of Henoch-Schonlein purpura.=20

    To evaluate the effects of serial intravascular transfusions on RhD-alloimmunized fetuses with ascites/hydrops at the time of the first transfusion by measuring multiple hematological/biochemical blood variables. Thirty-one singleton pregnancies were referred for management of RhD alloimmunization. Seven fetuses had hydrops on presentation and were transfused immediately. The remainder underwent weekly ultrasound examinations, and fetal blood sampling and transfusion were performed on development of ascites. In the 104 samples collected overall from the 31 fetuses, glucose, uric acid, urea, creatinine, total protein, total and direct bilirubin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyltransferase, alkaline phosphatase, lactic dehydrogenase, amylase, pseudocholinesterase (PCHE), creatine kinase, triglycerides and cholesterol were measured and compared with a reference range for non-anemic fetuses. The median gestational age at first transfusion was 26 (range, 18-34) weeks. There were three fetal losses after the first transfusion, two of which were due to procedure-related complications; one further loss occurred. At the first transfusion fetal hematocrit, pO2, total protein, PCHE, creatinine and urea concentrations were significantly decreased compared to reference data, while total and direct bilirubin, AST, ALT, amylase, triglyceride and uric acid concentrations were increased. In all surviving fetuses ascites/hydrops had disappeared by the second transfusion. Fetal pO2, total protein, AST, ALT and PCHE concentrations had normalized by the third transfusion. Correction of fetal anemia did not affect the other variables. RhD-alloimmunized fetuses with ascites/hydrops at the time of the first transfusion had a survival rate of 87%. Alterations of several biochemical fetal blood indices are present at the first sampling/transfusion, but most variables normalize with intravascular transfusions. Copyright 2005 ISUOG.

    Purpura annularis telangiectodes (PAT), also known as Majocchi purpura, is a rare form of pigmented purpuric dermatosis characterized by non-palpable red-brown, occasionally pruritic patches which progress to hyperpigmented halos. Purpura annularis telangiectodes usually presents in female adolescents as benign symmetric lesions with a predilection for the lower extremities. We present an atypical case of unilateral PAT in an elderly male. To our knowledge, our patient at 85-years-old is the oldest PAT and first unilateral purpura annularis telangiectodes case described in the literature.

    The aim of this study was to estimate the incidence of the disease and to analyze laboratory data of 23 newborns undergoing serologic testing for alloimmune neonatal neutropenia (ANN) during the 1998-2008 period in Croatia. Laboratory data on 23 newborns undergoing serologic testing for ANN during the 1998-2008 period and epidemiologic data on the number of live births in Croatia were analyzed. Laboratory testing for ANN included serologic screening of maternal and neonatal sera and granulocytes (neutrophils) by immunofluorescence (IF) method. The monoclonal antibody immobilization of neutrophil antigens (MAINA) was employed to determine anti-HNA antibody specificity. Anti-HNA antibodies were detected in seven (54%) of 13 cases of serologically positive ANN. Only anti-HLA class I antibodies were demonstrated in four (31%) of 13 cases In the 2007-2008 period of prospective data collection, the number of serologically verified ANN cases was one case per 17,323 live births. Results of the prospective study conducted at Maternity Ward, Department of Gynecology and Obstetrics, Sestre milosrdnice University Hospital Center yielded the ANN incidence of one case per 2843 live births. Monitoring of neutrophil count in neonatal blood and serologic testing for ANN in case of isolated neutropenia in the newborn contributed considerably to timely detection of ANN.

    Objective To investigate the effects of allograft inflammatory factor-1(AIF-1)and (RANTES) in sera and deciduas on unexplained early spontaneous abortion.Methods AIF-1 and RANTES were examined in sera and deciduas/endometria of 43 unexplained early spontaneous abortion women (group A),40 healthy women with early pregnancy(group B)and 20 healthy women with no pregnancy (group C). Immunohistochemistry and enzyme linked immunosorbent assay (ELISA) were used in this study. Results AIF-1 protein was expressed both in deciduas of group A and in endometria of group C.In group A, H scores in the recurrent abortion deciduas specimens were significantly greater than those in the first abortion;in endometrium,expression of AIF-1 was greater in the secretory than in proliferative phase of group C.In group B,concentrations of RANTES in sera were higher in 7th-8th week of pregnancy than in 6th-7th and >8th week of pregnancy;expression of AIF-1 protein showed a negative correlation with RASNTES concentration;a significant increase of the RANTES levels in sera and tissue was observed in group B. Conclusion These results demonstrate, for the first time,that AIF-1 are expressed in deciduas of unexplained spontaneous abortion suggesting that AIF-1 involve in alloimmune abortion; RANTES might act as a novel blocking antibody;AIF-1 and RANTES might act as reliable markers for diagnosis of early alloimmune abortion.

    To describe the natural history, antenatal and postnatal therapy, and clinical outcomes of Australian patients with fetomaternal/neonatal alloimmune thrombocytopenia (NAIT) recorded in the Australian NAIT registry. Analysis of registry data of Australian mothers treated antenatally for NAIT and any fetus/newborn with thrombocytopenia (TCP) and maternal human platelet antigen (HPA) antibodies. Ninety four potential cases (91 pregnancies; three twin pregnancies) were registered between December 2004 and September 2015 with 76 confirmed or treated as NAIT. NAIT was frequently unanticipated (44 cases, 58%), whilst 32 cases (42%) were anticipated due to personal or family history. In 70/76 cases, the diagnosis of NAIT was made based on HPA antibody results; anti-HPA-1a was most commonly detected (58/70, 82%), followed by anti-HPA-5b (5/70, 7%). Intracranial haemorrhage (ICH) was detected in seven cases (9%). Maternal antenatal therapy resulted in improved clinical outcomes. For antenatally treated cases, whilst 10/29 (34%) neonates had severe TCP, only one ICH was detected. This study provides data on contemporary "real world" management of Australian mothers and babies with NAIT. Antenatal IVIG therapy was associated with better neonatal outcomes. Maternal side-effects and treatment costs were substantial.

    Fetal and neonatal allo-immune thrombocytopenia (FNAIT) is considered as a rare disease due to the incidence (1/1000-1/2000 births). The major complication of severe thrombocytopenia is bleeding and particularly intra-cranial hemorrhage and neurologic sequelae following. Serology and molecular biology developments have reconfigured the platelet immunology diagnosis. Anti-HPA-1a allo-immunisation is responsible for more than 80% FNAIT cases with a high recurrence rate of severe bleeding complications. Therapeutic management has changed over the coming years from an invasive concept associating fetal blood sampling and in utero platelet transfusion to a non invasive treatment by intravenous immunoglobulins injection (IVIg). The purpose of this article is to provide an update on FNAIT management in the light of current developments over the past 30years. Copyright © 2017. Published by Elsevier SAS.

  5. Alloimmune Responses of Humanized Mice to Human Pluripotent Stem Cell Therapeutics

    Nigel G. Kooreman

    2017-08-01

    Full Text Available There is growing interest in using embryonic stem cell (ESC and induced pluripotent stem cell (iPSC derivatives for tissue regeneration. However, an increased understanding of human immune responses to stem cell-derived allografts is necessary for maintaining long-term graft persistence. To model this alloimmunity, humanized mice engrafted with human hematopoietic and immune cells could prove to be useful. In this study, an in-depth analysis of graft-infiltrating human lymphocytes and splenocytes revealed that humanized mice incompletely model human immune responses toward allogeneic stem cells and their derivatives. Furthermore, using an “allogenized” mouse model, we show the feasibility of reconstituting immunodeficient mice with a functional mouse immune system and describe a key role of innate immune cells in the rejection of mouse stem cell allografts.

    Fetomaternal alloimmune thrombocytopenia (FMAIT) caused by maternal antibodies is the leading cause of severe neonatal thrombocytopenia. A 1-month-old Caucasian girl was referred to our Hematology Clinic for persistent thrombocytopenia diagnosed after a bleeding episode. Diagnostic tests suggested FMAIT. Mild thrombocytopenia persisted for 18 months, and subsequent findings of dysmorphic facies, short stature and mild pulmonary stenosis led to the hypothesis of Noonan syndrome (NS), which was confirmed by genetic test. Other hematological abnormalities were excluded and she had no further bleeding episodes. This case illustrates the possibility of different diagnoses with the same clinical manifestations. The persistence of thrombocytopenia longer than expected associated with typical physical features led to the diagnosis of NS.

    Curative chemotherapy approaches in patients with malignancies and platelet (PLT) transfusion refractoriness due to alloimmunization may be hampered by the lack of suitable PLT donors. For these patients, transfusion of cryopreserved autologous PLTs is an option, but is time- and resource-consuming. We aimed at further simplifying this process. A retrospective single-center analysis was conducted on the transfusion of cryopreserved autologous PLTs in nine female alloimmunized, PLT transfusion-refractory patients treated for acute leukemia (n = 8) and non-Hodgkin's lymphoma (n = 1). No additional processing was used before transfusion, and most notably, washing and centrifugation steps were omitted. Clinical efficacy and safety, as well as a flow cytometric assessment of structural and functional PLT changes, were analyzed. A total of 40 autologous PLT concentrates were thawed at bedside and transfused a median of 32 (range, 9 to 994) days after cryopreservation. No major bleeds and no severe dimethyl sulfoxide toxicity were observed. The median PLT count increments did not differ 1 and 18 to 24 hours after transfusion and reached 6 × 10 9 /L (interquartile range [IQR], 3 × 10 9 -7.5 × 10 9 /L) and 6 × 10 9 /L (IQR, 2.5 × 10 9 -9.5 × 10 9 /L), respectively. Cryopreservation resulted in partial activation of one-third of the PLTs. In vitro stimulation with strong agonists induced additional full activation of cryopreserved PLTs: median, 55% (IQR, 42%-60%) after thrombin and 39% (IQR, 36%-39%) after convulxin. The transfusion of cryopreserved autologous PLTs is feasible and safe. Despite the cryopreservation process, PLT functionality is partially maintained. © 2016 AABB.

  8. Amount of platelet-bound IgG in chronic autoimmune thrombocytopenic purpura (ITP): absence of significant influence on platelet survival and destruction-site

    The amount of platelet-bound IgG, as measured with a direct Coombs radioactive antiglobulin test, could not be correlated with either platelet survival or the site of platelet destruction in 22 patients with chronic ITP. The amount of platelet-bound IgG may not be an index of severity in this disease, nor does it offer an indication on the site of destruction of platelets

    Immune thrombocytopenia (ITP) is an autoimmune hemorrhagic disorder characterized by reduction in platelet counts. T helper 1 (Th1) cells polarization with an increased shift of Th1/Th2 ratio has been reported in ITP. This shift is associated with transcription factor T-box expressed in T cells (T-bet) upregulation and GATA-binding protein 3 (GATA-3) downregulation, leading to an increased T-bet/GATA-3 ratio. Our previous in vitro study showed that recombinant human interleukin-11 (rhIL-11) could normalize Th1/Th2 imbalance in the peripheral blood mononuclear cells (PBMCs) isolated from adult ITP patients, which co-occurred with T-bet/GATA-3 ratio restoration. In this report, we investigated whether rhIL-11 had therapeutic effect in clinical ITP patients and whether rhIL-11 treatment could normalize Th1/Th2 and T-bet/GATA-3 levels in vivo. We found rhIL-11 treatment had a response rate of 67.7% and significantly decreased Th1 and T-bet levels but increased Th2 and GATA-3 levels in ITP patients who showed good response, normalizing Th1/Th2 and T-bet/GATA-3 ratios similar to that in healthy controls. Thus our study suggested rhIL-11 was effective with tolerable adverse effects in ITP. The treatment strategy warrants further clinical investigation. Copyright © 2016 Elsevier B.V.

    Immune Thrombocytopenia (ITP) is characterised by an autoimmune antibody-mediated destruction of platelets and impaired platelet production. Few controlled trials exist to guide management of patients with ITP in Indian scenario for which patients require an individualized approach. Anti-D (Rho (D) immune globulin) at a higher dose can prove to be a cost effective and safe alternative for Indian patients with ITP. To compare the safety and efficacy of higher dose (75μg/kg) intravenous Anti-D immune globulin against the standard dose of 50μg/kg for the management of ITP in Indian patients. One hundred and sixty four children with newly diagnosed ITP between 4-14 years were randomly selected for inclusion and were treated with 50μg/kg (standard dose) or 75μg /kg (higher dose) of Anti-D to compare the efficacy and safety of higher dose intravenous anti-D immune globulin. Efficacy of Anti-D was measured in terms of rate of response and median time to response for increase in platelet counts. Any adverse event was noted. A decrease in haemoglobin concentration suggested accompanying haemolysis. Seventy one out of 84 patients treated with Anti-D at 75μg/kg produced complete response (85%) with median time of response being 2.5 days. On the contrary, 45 patients (70%) patients treated with 50μg/kg had complete response. However, there was no significant increase in haemolysis with higher dose. A significant correlation was found between dose and peak increase in platelet count measured at 7 th day following administration. However, there was no relationship between the decrease in haemoglobin and the dose given, or between the increase in platelet count and fall in haemoglobin. A 75μg/kg dose of Anti-D is more effective with acceptable side effect in comparison to 50μg dose for treatment of newly diagnosed Indian patients of ITP.

    Conclusions: The SQBF had a similar effect to prednisone with regards to enhancing peripheral blood platelet counts in ITP mice. Furthermore, it decreased β-EP levels and increased VIP and SIgA, and protected the thymus. This shows that, on base of the brain-gut axis functions, some non-classical immune vascular active factors or neurotransmitters are also involved in immune responses, and also have relationship with the onset of ITP and bleeding and/or hemostasis. It needs further study to determine whether a change in these active factors is related to immediate hemostasis.

    The localized scleroderma (LS) known as morphea, presents a variety of clinical manifestations that can include systemic involvement. Current classification schemes divide morphea into categories based solely on cutaneous morphology, without reference to systemic disease or autoimmune phenomena. This classification is likely incomplete. Autoimmune phenomena such as vitiligo and Hashimoto thyroiditis associated with LS have been reported in some cases suggesting an autoimmune basis.

    2013-01-01

    A 43-year-old lady was admitted to the intensive care unit with sepsis. She had a history of mixed connective tissue disease, Raynaud\\'s syndrome and hypothyroidism. 2 days later, she developed a purpuric rash on her face and extremities with a livedoid background. Few days later, her distal fingers and toes became gangrenous which then had to be amputated. Laboratory investigations showed that she was coagulopathic and had multiple organ dysfunctions. Antiphospholipid antibodies were negative; however, protein C and antithrombin III levels were low. A skin biopsy showed fibrinoid necrosis in the vessel wall with microthrombi and red-cell extravasation. A diagnosis of purpura fulminans was made.

    Schonlein-Henoch purpura is the most common form of purpura in children. It can affect a number of organs, but scrotal involvement is rare. We present a case of scrotal hemorrhage and epidymo-orchitis, diagnosed by color Doppler ultrasound, in which conservative treatment was employed. The differential diagnosis involves testicular torsion, which is also, although less frequently, associated with Schonlein-Henoch purpura. color Doppler ultrasound results in the correct diagnosis, ruling out testicular torsion and avoiding surgical exploration of the testicles.

    Previous studies of Sub-Saharan Africans show significant alloimmunization to red blood cell (RBC) antigens, but country-specific data are limited. Thus, the aim of this study was to estimate, by meta-analysis, the overall proportion of red blood cell alloantibodies among transfused patients. We systematically searched Medline, Embase, and the Africa-Wide Information database to identify relevant studies in any language. Case reports, comments, letters, conference abstracts, editorials, and review articles were excluded. Of the 269 potentially relevant articles, 11 studies fulfilled our selection criteria. Overall proportions of alloimmunization were 6.7 (95% CI: 5.7, 7.8) per 100 transfused patients. With regard to antibody specificity, among clinically significant antibodies, anti-E ranked as the most common, followed by anti-K, anti-C and anti-D. Meta-analysis of available literature quantifies and qualifies the clinical challenge of RBC alloimmunization among transfused patients in Sub-Saharan Africa. These results should drive policy decisions in favour of routine testing of RBC antigens and irregular antibodies for transfused patients as a standard of care throughout Sub-Saharan Africa.

    Full Text Available Beta-thalassemia is one of the most prevalent autosomal disorders, which affect more than 400,000 newborn per year worldwide. In India, the carrier rate of beta-thalassemia varies from 3-17%. The overall rate of alloimmunization in thalassemia patients has been reported to be 5-30% in the world, which is mostly contributed by the alloimmunization to minor blood group antigen. Among Asians, the incidence of red cell alloimmunization is 22%. The recommended treatment for beta-thalassemia major is regular blood transfusion every 3 to 4 weeks. The development of anti-red cell antibodies (alloantibodies and/or autoantibodies can significantly complicate transfusion therapy. Alloantibodies are commonly associated with red cell hemolysis. Red cell autoantibodies appear less frequently, but they can result in clinical hemolysis called autoimmune hemolytic anemia (AIHA, and in difficulty in cross-matching blood. Patients with autoantibodies may have a higher transfusion rate and often require immunosuppressive drugs or alternative treatments including intravenous immunoglobulin (IVIg and rituximab (anti-CD20 monoclonal antibody.

    To evaluate carboxyhemoglobin (COHb) values measured with a CO-oximeter (Roche-cobas b 221) in jaundiced newborns with or without hemolysis and healthy controls in order to assess whether COHb measurement determined with a CO-oximeter could be used as an indicator of hemolysis in newborns with ABO alloimmunization. A total of 86 term newborn infants were prospectively studied. The study cohort consisted of three subgroups: 18 infants with ABO HDN, 21 infants with hyperbilirubinemia without hemolytic disease who required phototherapy, and 47 healthy controls. The COHb, bilirubin, and Hb levels were measured. The three subgroups did not differ significantly with respect to birth weight, gestational age, gender, Apgar score, or mode of delivery. The ABO HDN infants had significantly higher COHb values than the healthy controls (median 2.4% versus 1.3%, p < 0.0005) and the group with hyperbilirubinemia without hemolytic disease (median 2.4% versus 1.3%, p < 0.0005), although the infants with hyperbilirubinemia without hemolytic disease did not have significantly higher COHb values compared with the healthy controls. The cut-off value of 1.7% COHb had 72% sensitivity and 97% specificity for confirming hemolysis in ABO alloimmunization. Our data show that COHb values determined with CO-oximeters are higher in newborns with hemolysis than in those without hemolysis. COHb measured with CO-oximeters could be used to confirm hemolysis in infants with ABO alloimmunization.

    Full Text Available Background: Although the relation of the gut microbiota to a development of autoimmune and inflammatory diseases has been investigated in various animal models, there are limited studies that evaluate the effect of probiotics in the autoimmune eye disease. Therefore, we aimed to investigate the effect of IRT-5 probiotics consisting of Lactobacillus casei, Lactobacillus acidophilus, Lactobacillus reuteri, Bifidobacterium bifidum, and Streptococcus thermophilus on the autoimmunity of uveitis and dry eye and alloimmunity of corneal transplantation. Methods: Experimental autoimmune uveitis was induced by subcutaneous immunization with interphotoreceptor-binding protein and intraperitoneal injection of pertussis toxin in C57BL/6 (B6 mice. For an autoimmune dry eye model, 12-weeks-old NOD.B10.H2b mice were used. Donor cornea of B6 mice was transplanted into BALB/C mice. IRT-5 probiotics or phosphate buffered saline (PBS were administered for three weeks immediately after induction of uveitis or transplantation. The inflammation score of the retinal tissues, dry eye manifestations (corneal staining and tear secretion, and graft survival were measured in each model. The changes of T cells were evaluated in drainage lymph nodes using fluorescence-activated cell sorting. Results: Retinal histology score in IRT-5 group of uveitis was lower than that in PBS group (p = 0.045. Ocular staining score was lower (p < 0.0001 and tear secretion was higher (p < 0.0001 in the IRT-5 group of NOD.B10.H2b mice than that in the PBS group. However, the graft survival in the IRT-5 group was not different from those of PBS group. The percentage of regulatory T cells was increased in the IRT-5-treated dry eye models (p = 0.032. The percentage of CD8+IL-17hi (p = 0.027 and CD8+ interferon gamma (IFNγhi cells (p = 0.022 were significantly decreased in the IRT-5-treated uveitis models and the percentage of CD8+IFNγhi cells was markedly reduced (p = 0.036 in IRT-5-treated dry

    Henoch-Schönlein purpura (HSP) is less common in adults and has been linked with a more severe clinical syndrome as well as a higher frequency of renal disease and internal malignancy. Renal involvement in adult HSP has been significantly associated with antecedent infections, pyrexia at time of first presentation, and purpura above the waist. We aim to evaluate the frequency of cutaneous and extra-cutaneous features and identify the predictive factors for renal involvement in Asian adults with HSP. We performed a retrospective study of 48 adult Asian patients diagnosed with HSP based on the European League Against Rheumatism (EULAR) criteria at a tertiary hospital in Singapore between January 2000 and December 2011. The most common cutaneous manifestations were palpable purpura (73%), papules (31%), and petechiae (27%). Forty-percent had cutaneous lesions extending above the waist. Fifteen patients (31%) had gastrointestinal symptoms, 21 (44%) had joint involvement, and 27 (56%) had renal disease. Seventy-percent of patients with pyrexia at presentation experienced renal disease, whereas only 30% without pyrexia had renal involvement (P = 0.018). Sixty-six percent of patients with purpura had renal involvement as compared to 31% in those without purpura (P = 0.049). The frequency of renal involvement in patients with purpura above the waist (52%) was similar to those with purpura below the waist (55%). Our study confirms that HSP in adults tends to be more severe with a high incidence of extracutaneous manifestations, especially renal disease. Pyrexia at presentation and the presence of purpura were significant predictive factors for renal involvement. © 2015 The International Society of Dermatology.

    2014-01-15

    Imatinib mesylate is a selective tyrosine kinase inhibitor used in the treatment of chronic myelogenous leukemia. Ocular side effects of imatinib include periorbital edema, which may become so severe as to obstruct the visual field. The purpose of this case study is to describe the clinical characteristics of imatinib- induced postoperative periorbital purpura. We retrospectively reviewed the medical literature using PubMed, searching the terms edema, Gleevec, imatinib, periorbital, postoperative and purpura. Patient reports and previous reviews of the subject were critically assessed and the salient features are presented. Three patients have undergone surgery to reduce the imatinib-induced periorbital edema; two of these individuals have developed imatinib-induced postoperative periorbital purpura. We recommend discontinuing imatinib usage one week prior to periorbital surgery and not resuming therapy until the eighth postoperative day.

    2017-08-01

    Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a relatively rare but potentially lethal disease, leading to severe bleeding complications in 1 in 11.000 newborns. It is the leading cause of thrombocytopenia in healthy term-born neonates. Areas covered: This review summarizes the antenatal as well as postnatal treatment, thus creating a complete overview of all possible management strategies for FNAIT. Expert commentary: The optimal antenatal therapy in order to prevent bleeding complications in pregnancies complicated by FNAIT is non-invasive treatment with weekly intravenous immunoglobulin (IVIG). Based on risk stratification, weekly doses of IVIG of 0.5 or 1.0g/kg should be administered started early in the second in high risk cases or at the end of the second trimester in low risk cases. The optimal postnatal treatment depends on the platelet count and the clinical condition of the newborn. Prompt administration of compatible platelet transfusion is the first treatment of choice in case of severe thrombocytopenia or active bleeding. In case matched platelets are not directly available, random platelets can also be administered initially to gain time until matched platelets are available. In case of persistent thrombocytopenia despite transfusions, IVIG 1.0-2.0g/kg can be administered.

    Both purpura fulminans and toxic epidermal necrolysis (TEN) are rare and life-threatening disorders with a high mortality. We present a case of suspected rapidly progressive, severe pneumococcal sepsis-induced purpura fulminans complicated by multiple organ failure, severe epidermolysis and cutaneous necrosis. We show the diagnostic challenge to differentiate between purpura fulminans and TEN, as the extensive epidermolysis in purpura fulminans may mimic TEN and we highlight the additional value of repeated skin biopsies and 16S rRNA gene sequencing.

    2015-08-01

    The incidence of mild to severe levels of spontaneous bleeding due to the usage of selective serotonin reuptake inhibitors (SSRIs) is relatively low. Although the exact mechanism is not known, it is thought that inhibition of the serotonin transporter together with a decrease in platelet serotonin could be responsible for the bleeding. Therefore, the use of SSRIs in conjunction with anti-aggregants may predispose to or exacerbate the risk of bleeding. In this case report, we describe a 44-year-old female patient with a diagnosis of anxiety disorder who spontaneously developed periorbital purpura during treatment with sertraline. Abnormal bleeding after treatment with an SSRI should be kept in mind, and alternative non-SSRI drugs of choice in such cases would be more appropriate. More extensive and comprehensive studies focusing on hemostasis and bleeding disorders are needed for SSRIs such as sertraline. © The Royal Australian and New Zealand College of Psychiatrists 2015.

    2015-12-01

    Full Text Available Introduction: Henoch schonlein purpura (HSP is a self-limited systemic disease with multiorgan involvement. While cutaneous involvement may wary, presenting as itching papules is not a common manifestation. In this report we discuss a case of HSP which was presented solely with itching papules; mistaken for scabies. Case presentation: A 7 year old boy presented with itchy palpable papules without any gastrointestinal or urinary problem which was primary taught to be an ectoparasitic infestation. During the hospitalization the patient developed abdominal pain as well as hematuria and the diagnosis became more evident. The skin biopsy showed perivascular inflammatory cells infiltration in epidermis, perivascular fibrinoid necrosis and leukocytoclastic vasculitis. The patient received corticosteroids and discharged healthy.Conclusion: While HSP may have different cutaneous manifestation, presenting as only itchy papules may complicate the diagnosis and physicians should always keep in mind that HSP might be presented as other common infestations unresponsive to treatment.

  12. Henoch-Schonlein purpura: ultrasonography of scrotal and penile involvement

    2015-04-01

    Full Text Available Testicular or scrotal involvement has been reported in children with Henoch-Schonlein purpura (HSP, but there are very few reports on penile involvement. We report the initial and follow-up ultrasonographic findings of scrotal and penile involvement of HSP in a 5-year-old boy. On ultrasonography, scrotal soft tissue thickening and epididymal swelling with increased vascularity were noted, and on the penis, a focal mass-like lesion appeared on the dorsal surface of the distal penis, having a hypoechoic mass-like appearance without visible vascular flow on a Doppler study. After 2 days of treatment, follow-up ultrasonography showed normal scrotum and penis with a resolved soft tissue mass-like lesion. Therefore, we think that HSP ultrasonographic findings involving the scrotum and penis might help to diagnose scrotal and penile involvement in a case of HSP and to avoid unnecessary medication and/or surgical procedures.

    2017-01-01

    Full Text Available Henoch–Schonlein purpura (HSP with facial involvement with bullous rashes are extremely rare. A 12-year-old boy presented with abdominal pain and features of arthritis. He also had multiple purpuric rashes over his lower limbs. Gradually, he developed bullous rashes which were seen on his legs and hands and progressed to involve the face. He was confirmed to be suffering from HSP from clinical presentation and skin biopsy. The child responded well to oral steroids. Bullous lesions may be seen in HSP. However, there is neither prognostic significance of this nor does it alter the management. Other causes of bullous lesions should be ruled out. As facial involvement is associated with renal and gastrointestinal involvement, these children should be monitored for sequelae.

    Full Text Available A 23-day-old neonate, born of nonconsangious marriage, admitted to Neonatal Intensive Care Unit for hypernatremic dehydration with petechiae and ecchymotic patches and necrotic skin lesions for 10–12 days was referred to dermatology department. On the general examination, pulse was 158/min, and respiratory rate was 52/min, and systemic examination was normal. Hematological investigations showed pancytopenia. Bleeding time was normal but prothrombin time and activated partial thromboplastin time reports were prolonged. D-dimer levels were elevated. Urine and stool were normal. Blood culture and sensitivity report revealed the growth of Citrobacter species with sensitivity to ciprofloxacin, amikacin, tetracycline, and resistance to Imipenem. Histopathology revealed epidermal hyperkeratosis with epidermal-dermal splitting, vessels showing fibrin occlusion with red blood cell extravasation into the perivascular areas in dermis along with dermal necrosis. To the best of our knowledge, this might be the first case of purpura fulminans in a neonate caused by rare Citrobacter species.

    When dogs are transfused, blood compatibility testing varies widely but may include dog erythrocyte antigen (DEA) 1 typing and rarely cross-matching. Prospective study to examine naturally occurring alloantibodies against red blood cells (RBCs) and alloimmunization by transfusion using 2 antiglobulin-enhanced cross-match tests. Eighty client-owned anemic, 72 donor, and 7 control dogs. All dogs were typed for DEA 1 and some also for DEA 4 and DEA 7. Major cross-match tests with canine antiglobulin-enhanced immunochromatographic strip and gel columns were performed 26-129 days post-transfusion (median, 39 days); some dogs had an additional early evaluation 11-22 days post-transfusion (median, 16 days). Plasma from alloimmunized recipients was cross-matched against RBCs from 34 donor and control dogs. The 2 cross-match methods gave entirely concordant results. All 126 pretransfusion cross-match results for the 80 anemic recipients were compatible, but 54 dogs died or were lost to follow up. Among the 26 recipients with follow-up, 1 dog accidently received DEA 1-mismatched blood and became cross-match-incompatible post-transfusion. Eleven of the 25 DEA 1-matched recipients (44%) became incompatible against other RBC antigens. No naturally occurring anti-DEA 7 alloantibodies were detected in DEA 7- dogs. The antiglobulin-enhanced immunochromatographic strip cross-match and laboratory gel column techniques identified no naturally occurring alloantibodies against RBC antigens, but a high degree of post-transfusion alloimmunization in dogs. Cross-matching is warranted in any dog that has been previously transfused independent of initial DEA 1 typing and cross-matching results before the first transfusion event.

    The use of 8-methoxypsoralen (8-MOP) and UV-A irradiation to inactivate contaminating donor leukocytes in platelet concentrates and to prevent primary alloimmunization against donor class I major histocompatibility (MHC) antigens in mice was investigated. CBA/CaH-T6J mice with the H2k haplotype and BALB/cByJ mice with the H2d haplotype were used as donors and recipients, respectively. The mixed leukocyte reaction between these two strains of mice showed that treatment of spleen cells with 500 ng/mL 8-MOP and 5J/cm2 UV-A inhibited 99% of responder and 92% of stimulator function. There was no measurable loss of platelet aggregating activity after the treatment. After two weekly transfusions of platelets without any treatment, 93% of control mice (n = 15) developed anti-H2k antibody. In contrast, only 33% of mice (n = 15) receiving platelets treated with 8-MOP and UV-A became alloimmunized. After six weekly platelet transfusions, all mice became alloimmunized. Nevertheless, the mean titers of anti-H2k antibody in sera of the treated groups were significantly lower than the control groups. One hour posttransfusion recoveries of 51Cr-labeled donor platelets were also higher in mice transfused with the treated platelets. Thus, the pretreatment of platelet concentrates with 8-MOP and UV-A irradiation effectively reduced the alloantigenicity of class I MHC molecules. The implication of this finding in relation to the mechanism by which donor leukocytes allosensitize recipients is discussed

    To examine the changes in 25-hydroxyvitamin D 3 [25-(OH)D 3 ] level in children with Henoch-Schönlein purpura (HSP) and its clinical significance. A total of 92 HSP children were included in this study, and were divided into HSP nephritis (HSPN) group (31 cases) and HSP group (61 cases) based on the presence or absence of HSPN. Alternatively, the patients were divided into purpura alone group (22 cases), purpura with joint symptoms group (joint symptom group, 24 cases), purpura with gastrointestinal symptoms group (gastrointestinal symptom group, 20 cases), and purpura with joint and gastrointestinal symptoms (mixed group, 26 cases) based on their clinical symptoms. In addition, 42 healthy children were selected as healthy control group. The level of 25-(OH)D 3 in each group was measured using enzyme-linked immunoassay. The 25-(OH)D 3 level in the HSP and HSPN groups was significantly lower than that in the healthy control group (Ppurpura alone group (P<0.05). The level of 25-(OH)D 3 is reduced in children with HSP, particularly those with HSPN or with joint and gastrointestinal symptoms. Therefore, the reduction in 25-(OH)D 3 level may serve as a predictor of whether HSP is associated with other impairments.

    Full Text Available Type 1 diabetes (T1D results from destruction of pancreatic beta cells by T cells of the immune system. Despite improvements in insulin analogs and continuous blood glucose level monitoring, there is no cure for T1D, and some individuals develop life-threatening complications. Pancreas and islet transplantation have been attractive therapeutic approaches; however, transplants containing insulin-producing cells are vulnerable to both recurrent autoimmunity and conventional allograft rejection. Current immune suppression treatments subdue the immune system, but not without complications. Ideally a successful approach would target only the destructive immune cells and leave the remaining immune system intact to fight foreign pathogens. This review discusses the autoimmune diabetes disease process, diabetic complications that warrant a transplant, and alloimmunity. First, we describe the current understanding of autoimmune destruction of beta cells including the roles of CD4 and CD8 T cells and several possibilities for antigen-specific tolerance induction. Second, we outline diabetic complications necessitating beta cell replacement. Third, we discuss transplant recognition, potential sources for beta cell replacement, and tolerance-promoting therapies under development. We hypothesize that a better understanding of autoreactive T cell targets during disease pathogenesis and alloimmunity following transplant destruction could enhance attempts to re-establish tolerance to beta cells.

    BHNN is an affection in which life duration of fetus red cells is decreased by means of maternal antibodies opposing certain antigens inherited from the father.The present study will prove the importance of laboratory tests in the diagnosis of alloimmunization through pregnancy and BHNN. Laboratory determinations were performed between March 2008 and February 2009 on samples from 187 Rh negative pregnant female with incompatible pregnancy and Rh D positive newborns; there was used a certain algorithm for and identifying. After applying the proposed algorithm, 4.2% of the cases were discovered to be immunized, whereas 2.6% of the cases were BHNN. As the specificity of irregular antibodies involved, 62.5% were anti D, 25% anti Kell and 12.5% anti E. The results show the fact that the incidence of these pathological entities is far more extended than in other countries. Owing to the fact that alloimmunization by pregnancy and BHNN is still a frequent phenomenon, an attentive supervision is very important both for preparing the patient and the medical team aiming to prevent perinatal morbidity.

    Henoch-Schönlein purpura is an immunoglobulin A-mediated, small vascular inflammatory disease that can be associated with palpable purpura, arthralgia, abdominal pain, or nephritis. The presence of purpura facilitates the diagnosis of Henoch-Schönlein purpura at the onset of associated symptoms, whereas the absence of purpura makes the diagnosis challenging. It is important to diagnose Henoch-Schönlein purpura with delayed-onset skin purpura to avoid unnecessary surgery for acute abdomen. Most cases of Henoch-Schönlein purpura with severe abdominal pain are treated with low-dose steroids and intravenous immunoglobulin. A 15-year-old Korean girl complained of severe abdominal pain and delayed-onset purpura on admission. Henoch-Schönlein purpura was diagnosed based on endoscopic findings of hemorrhagic duodenitis and duodenal vasculitis and abdominal computed tomography findings of edematous bowels. Two common initial treatments, a low-dose steroid and intravenous immunoglobulin, were administered, but there was no improvement for 1 month. Subsequently, we used high-dose intravenous methylprednisolone pulse therapy (30 mg/kg/day, with a maximum of 1g/day), which dramatically alleviated her abdominal symptoms. High-dose intravenous methylprednisolone pulse therapy can be used as the ultimate treatment for delayed-onset Henoch-Schönlein purpura with severe abdominal pain when symptoms do not improve after low-dose steroid and intravenous immunoglobulin treatments.

    Henoch-Schönlein purpura is a systemic vasculitis of the small vessels characterized by perivascular leucocyte infiltrates. It is an immunoglobulin A-related immune complex-mediated disease involving the skin, the joints and the gastrointestinal system. Renal disease may sometimes be associated to these clinical manifestations. Prevalence of the nephritis is highly variable, depending on the series. More rarely, other organs such as the lungs, the heart or the nervous system may be involved. The clinical diagnosis is confirmed by histopathology of the skin (leukocytoclastic vasculitis) and kidney (endo-capillary proliferative glomerulonephritis), showing IgA deposits in these tissues. Short-term prognosis depends on the severity of digestive involvement, but long-term prognosis depends on the renal disease. Recent publications of pediatric and adult series show that the chronic renal failure may progress, sometimes more than ten years after the initial flare. Treatment is usually supportive. The benefit of more specific treatments (corticosteroids or immunosuppressive drugs) in severe visceral forms (usually abdominal or kidney) has not yet been established.

    A 72-year-old man had underwent left lower lobectomy for squamous cell carcinoma in our hospital in 2008. Postoperative stage was I A (T1N0M0). In 2010, follow-up chest computed tomography (CT) images showed similar cavitary nodules in segments 2 and 8 of the right lung with positive uptake on fluorodeoxyglucose-positron emission tomography (FDG-PET) images. Physical examination, blood tests, and levels of serum tumor markers showed no abnormality. Transbronchial lung biopsy revealed the absence of malignant cells. Segment 8 of the right lower lobe with the nodule was partially resected, and pathological examination demonstrated lung abscess. He was discharged but was hospitalized in another hospital for purpuric rash, fever, and arthralgia. Microscopic albuminuria was noted, and renal biopsy revealed nephritis with immunoglobulin A( IgA)deposition. He was made a diagnosis of Henoch-Schönlein purpura. Oral steroid therapy( prednisolone 60 mg/d) was initiated, resulting in the improvement of symptoms and disapearance of the cavitary nodule in the right lung segment 2.

    As the morphological and immunohistochemical manifestations of immunoglobulin A (IgA) nephropathy and Henoch-Schonlein purpura nephritis (HSPN) are very similar, they are considered to share a common pathogenesis. Although HSPN usually develops after the appearance of anaphylactoid purpura, we have encountered patients whose renal symptoms preceded purpura. We reviewed the clinical courses of patients who were first diagnosed with IgA nephropathy, but developed purpura later, at the National Center for Child Health and Development in Tokyo, Japan. Of the 53 patients who were diagnosed with primary IgA nephropathy at our institute during the study period (March 2002 to July 2015), six (11 %) developed anaphylactoid purpura after the diagnosis of primary IgA nephropathy and therefore met the inclusion criteria. Duration between the onset of nephritis and subsequent appearance of purpura ranged from 5 months to 14 years. One patient reached end-stage renal failure due to IgA nephropathy and developed purpura after renal transplantation. All renal biopsies performed before the appearance of purpura showed mesangial proliferation with predominant IgA deposits. Urinary findings deteriorated in three patients after the appearance of purpura, including one patient who developed rapidly progressive glomerulonephritis. Renal biopsy findings worsened in two patients. At the last observation, two patients showed mild renal insufficiency. Our clinical experience and previous reports support the argument that IgA nephropathy and HSPN are different manifestations of a single disease. Hence, it is acceptable to consider that they are variants of a single disease.

    In this study, two school-aged children had an acute onset in spring and had the manifestations of fever, headache, vomiting, disturbance of consciousness, purpura and ecchymosis, and positive meningeal irritation sign. There were increases in peripheral white blood cells and neutrophils, but reductions in the hemoglobin level and platelet count in the two children. They had a significant increase in C-reactive protein. There were hundreds or thousands of white blood cells in the cerebrospinal fluid, mainly neutrophils. Increased protein contents but normal levels of glucose and chloride in the cerebrospinal fluid were found. Head CT scan showed multiple hematomas in the right cerebellum and both hemispheres in one child. Bone marrow cytology indicated infection in the bone marrow, and both blood culture and bone marrow culture showed methicillin-resistant Staphylococcus aureus (MRSA). Both patients had cardiac murmurs and progressive reductions in the hemoglobin level and platelet count during treatment, and echocardiography showed the formation of vegetation in the aortic valve. Therefore, the patients were diagnosed with infectious endocarditis (IE). Vancomycin was used as the anti-infective therapy based on the results of drug sensitivity test. One child was cured after 6 weeks, and the other child was withdrawn from the treatment and then died. Dynamic monitoring of cardiac murmurs should be performed for children with unexplained fever, and echocardiography should be performed in time to exclude IE. IE should also be considered for children with purulent meningitis and skin and mucosal bleeding which cannot be explained by the reduction in platelet count.

    Full Text Available Background. Hemorrhagic vasculitis, or Schönlein-Henoch purpura (SHP, is the most common type of systemic vasculitis in childhood, and peculiarities of the further evolution of the pathological process in adult patients remain unexplored. Objective: to study the evolution of juvenile SHP, comparing the nature of lesions of the skin, joints, heart and kidneys in patients in childhood and adulthood. Material and methods. The study included 92 patients (61 men and 31 women with the average age of 27 years, and the average age of disease onset — 11 years. I degree of the activity of the pathological process is determined in 40 % of cases, II — in 35 %, III — in 25 %. Seropositivity by hyperimmunoglobulinemia A occurred in 27 % of cases, by the presence of rheumatoid factor — in 21 %. At the time of the survey, cutaneous syndrome was diagnosed in 55 % of patients, joint one — in 45 %, kidney one — in 71 %. Renal biopsy was performed in 15 cases. Results. The cutaneous, cutaneous-joint-abdominal and cutaneous-abdominal-renal forms of the disease, lesions of the skin, gastrointestinal tract, wrist, ankle and knee joints become rarer in the process of juvenile SHP evolution, but exceptionally renal variant of the pathological process, changes of skeletal muscles, liver, spleen and the heart are revealed more often, chronic kidney disease with the renal failure progression is developed in 12 % of patients (in 17 % of cases of nephropathy, sacroiliitis, spondylopathy, tendovaginitis, enthesopathies, epiphyseal osteoporosis and meniscitis of the knee joints are arisen, II, III, VI and IV morphological classes of Henoch glomerulonephritis are formed in a ratio of 8 : 4 : 2 : 1 with tubulointerstitial component in all cases, and lymphohistiocytic infiltration of the vascular wall is the unfavorable sign for the prognosis of the disease. Conclusions. In cases of transition of juvenile SHP into the chronic adult form, the disease often obtain

    Objective: To evaluate the usefulness of CT and US in the diagnosis of gastrointestinal involvement in children with rheumatoid purpura. Methods: Abdominal CT and US findings in 14 cases of clinical and laboratory confirmed of rheumatoid purpura were analyzed. There were 9 males and 5 females with the age ranged from 6 months to 14 years. All patients was hospitalized because of acute abdominal emergency, and the clinical presentations included paroxysm of abdomen pain, vomiting, without skin rashes and subcutaneous hemorrhage. CT examination was done in 7 cases, and contrast enhancement was performed in 1 case. Abdominal ultrasound was done in 9 cases. Both CT and US were done in 2 cases. Results: All patients demonstrated multiple or single areas of bowel-wall thickening, localized intraluminal narrowing, mesenteric edema, and liquid in abdominal cavity by CT and ultrasound. Conclusion: Abdominal CT and US examination have important values in differential diagnosis of acute abdominal disorders in children patients with rheumatoid purpura. Before appearing skin rashes, classical picture can help for the diagnosis and clinical treatment. Abdominal CT and US examination can also find the intussusception, bowel obstruction, and perforation in rheumatoid purpura

    2013-08-01

    To study the clinical and pathological features of cases of apparent solar purpura, with attention to the recently described phenomenon of inflammatory changes within otherwise typical lesions. We studied 95 cases diagnosed as solar purpura and identified 10 cases (10.5%) in which significant neutrophilic inflammation was present, potentially simulating a leukocytoclastic vasculitis or neutrophilic dermatosis. An additional three cases were identified in subsequent routine practice. The clinical features, including follow-up for subsequent development of vasculitis and histological features were studied. In all cases the histological features were typical of solar purpura, with the exception of inflammatory changes, typically associated with clefting of elastotic stroma. Clinical follow-up information was available for all patients and none developed subsequent evidence of a cutaneous or systemic vasculitis or neutrophilic dermatosis. Inflammatory changes appear to be more frequent in solar purpura than is generally recognised. Awareness of this histological variation and correlation with the clinical findings and evolution is important in avoiding misdiagnosis.

    To explore the clinical characteristics of Henoch-Schönlein purpura (HSP) in children. The clinical data of 325 hospitalized children who were diagnosed with HSP between June 2012 and June 2014 were analyzed retrospectively. In the 325 children with HSP, the incidence of HSP was higher in winter and spring, with 33.9% and 27.4%, respectively. Infection was the major factor to induce HSP (57.2%). The incidence of renal damage in children with purpura accompanied by abdominal symptoms and children with purpura accompanied by abdominal and joint symptoms was 60.3% and 48.9%, respectively, with statistically significant differences compared with children with purpura alone (Ppurpura nephritis, the pathological grades of IIIa and IIIb were more common, accounting for 28% and 31%, respectively. In 325 children, an increased serum D-dimer level was observed in 260 children (80.0%), an increased peripheral IgA content in 101 children (46.3%), and a decreased CD4+ cell percentage in 62 children (56.4%). A high incidence of HSP is often seen in spring and winter. HSP is often induced by upper respiratory tract infection. Renal damage is more likely to occur in children with digestive tract symptoms, with IIIa and IIIb as the common pathological grades of renal damage.

    2008-06-01

    Full Text Available Abstract Introduction Henoch-Schönlein purpura is a small vessel vasculitis that affects mainly the skin, joints, gastrointestinal tract and kidneys. The central nervous system is also occasionally affected, although the majority of patients experience only mild symptoms such as headaches and behavioural changes. Intracerebral haemorrhage is a rare complication of Henoch-Schönlein purpura that so far has mainly been described in children and young adolescence. Case presentation We describe a 42-year-old man with Henoch-Schönlein purpura who developed an acute intracerebral haemorrhage that coincided with a reactivation of his vasculitis and the development of renal failure following discontinuation of steroids. In this patient, both the Henoch-Schönlein purpura and his neurological symptoms were successfully treated with intravenous cyclophosphamide and methylprednisolone, followed by a short course of oral cyclophosphamide and long-term oral prednisolone. His renal function also recovered sufficiently not to require renal replacement therapy. Conclusion The management of Henoch-Schönlein nephritis remains unclear, especially in the presence of severe complications such as intracerebral haemorrhage. We describe a successful outcome in such a patient.

    Psychogenic purpura (Gardner-Diamond syndrome) is the occurrence and spontaneous recurrence of painful ecchymosis following emotional stress and minor trauma. Although the exact mechanism of this syndrome remains unknown, apart from skin lesions, different types of hemorrhaging have been reported, such as epistaxis, gastrointestinal bleeding, and bleeding from the ear canals and eyes. We report a psychogenic purpura case that presented with hematuria in addition to skin lesions. Based on the psychiatric evaluation she was diagnosed with major depressive disorder, generalized anxiety disorder, and obsessive-compulsive disorder. Additionally, sexual pain disorder accompanied these disorders. With the help of antidepressant and supportive psychotherapy, the patient's ecchymosis and bleeding disappeared. During 8 months of follow-up the symptoms did not return. Vaginismus has not been reported in patients with psychogenic purpura. The presence of vaginismus, which is seen more frequently in eastern cultures and is thought to be related to sociocultural determinants, suggests that some cultural factors may be common to both psychogenic purpura and vaginismus. The aim of this case report was to call attention to a syndrome that is rarely seen and diagnosed, and to discuss its relationship to psychosocial factors. This syndrome should be considered in the differential diagnosis of not only ecchymotic lesions, but also various types of bleeding, including hematuria. Despite the fact that its etiology and treatment are not clearly understood, it should be noted that psychological factors play a role in this disease and therefore, psychopharmacological and psychotherapeutic approaches can be effective.

    Purpura fulminans is a rapidly progressive syndrome of small-vessel thrombosis and hemorrhagic necrosis of the skin accompanied by disseminated intravascular coagulation. We describe a case of Streptococcus pneumoniae septicemia in an asplenic 5-year-old boy on oral tacrolimus, with a past medical history of multivisceral organ transplantation and subsequent development of purpura fulminans on his chest and distal extremities. The acute infectious form of purpura fulminans is usually caused by gram-negative bacteria. Cases secondary to gram-positive encapsulated bacteria usually occur when individuals are immuno-suppressed or have anatomic or functional asplenia. Our patient had both, which likely increased his susceptibility, and he responded well to antimicrobial therapy in addition to prophylactic coverage in the setting of his immunosuppression. We review the literature for similar cases due to S. pneumoniae in the pediatric population and discuss the etiology and treatment of purpura fulminans.

    Rh-isoimmunization is a pathological condition in which the fetal red blood cells of a Rh (+) fetus are destroyed by the isoantibodies of a Rh (-) woman sensitized in a previous event. Despite of the wide spread implementation of anti D-gammaglobolin prophylaxis this is still the most common cause for fetal anemia. Recently, sonographic measurement of the fetal middle cerebral artery peak systolic velocity (MCA-PSV) has been shown to be an accurate non-invasive test to predict low fetal hemoglobin levels. We present a case report of Rh-alloimmunized pregnancy with moderate fetal anemia, followed-up by weekly MCA-PSV measurements. A 37-year-old Rh (-) negative gravida 3, para 1, without anti-D gammaglobolin prophylaxis in her previous pregnancies, presented at 27+0 weeks of gestation (w.g.) for a routine third trimester scan. Subsequent ultrasound measurements of MCA-PSV confirmed a progressive increase of the peak systolic velocities from 40 to 80 cm/sec, as well as a gradual rise in the anti-D titers. The evidence of developing fetal anemia necessitated elective Caesarean section performed at 35 wg. The neonate was admitted in the intensive care unit and required resuscitation, one exchange blood transfusion and several courses of phototherapy. The patient was discharged two weeks post partum. There is a strong correlation between the high peak systolic velocities in the middle cerebral artery (MCA-PSV) and the low levels of fetal hemoglobin. The high sensitivity and positive predictive value concerning the development of fetal anemia, as well as its good repeatability, makes this non-invasive test a valuable asset in the management of all pregnancies complicated by severe Rh-alloimmunization.

  16. Targeted in vitro and in vivo gene transfer into T Lymphocytes: potential of direct inhibition of allo-immune activation

    2006-11-01

    Full Text Available Abstract Background Successful inhibition of alloimmune activation in organ transplantation remains one of the key events in achieving a long-term graft survival. Since T lymphocytes are largely responsible for alloimmune activation, targeted gene transfer of gene of cyclin kinase inhibitor p21 into T cells might inhibit their aberrant proliferation. A number of strategies using either adenoviral or lentiviral vectors linked to mono or bispecific antibodies directed against T cell surface markers/cytokines did not yield the desired results. Therefore, this study was designed to test if a CD3promoter-p21 chimeric construct would in vitro and in vivo transfer p21 gene to T lymphocytes and result in inhibition of proliferation. CD3 promoter-p21 chimeric constructs were prepared with p21 in the sense and antisense orientation. For in vitro studies EL4-IL-2 thyoma cells were used and for in vivo studies CD3p21 sense and antisense plasmid DNA was injected intramuscularly in mice. Lymphocyte proliferation was quantified by 3H-thymidine uptake assay; IL-2 mRNA expression was studied by RT-PCR and using Real Time PCR assay, we monitored the CD3, p21, TNF-α and IFN-γ mRNA expression. Results Transfection of CD3p21 sense and antisense in mouse thyoma cell line (EL4-IL-2 resulted in modulation of mitogen-induced proliferation. The intramuscular injection of CD3p21 sense and antisense plasmid DNA into mice also modulated lymphocyte proliferation and mRNA expression of pro-inflammatory cytokines. Conclusion These results demonstrate a novel strategy of in vitro and in vivo transfer of p21 gene to T cells using CD3-promoter to achieve targeted inhibition of lymphocyte proliferation and immune activation.

    Senile purpura presents itself as a largely unexplored challenge as it has been long thought of as a benign condition without long-term health sequelae. It is becoming increasingly accepted that skin aging not only results in cosmetic disturbances, but as a functional ones. With modern increases in lifespan, skin atrophy associated with solar damage is presenting as a clinically significant inability to mechanically protect patients. This chronic cutaneous insufficiency/fragility syndrome was recently termed dermatoporosis and senile purpura appears to be a visible marker of early stage dysfunction. To examine the effects of topically human epidermal growth factor on the clinical presence of senile purpura and its effect on skin thickness as measured via cutaneous ultrasound. Six subjects applied human epidermal growth factor morning and night for six weeks. Clinical outcomes were evaluated by comparing initial clinical photos to 6-week photos and performing a blinded investigator's global assessment (IGA). Skin thickness was evaluated via cutaneous ultrasound measurement. Ultrasound measurements indicated a mean skin thickening of 195.2 ± 35.7 um (SEM) over 6 weeks. The average number of purpuric lesions decreased from 15 ± 4.6 (SEM) to 2.3 ± 0.7 (SEM) over that same period. Senile purpura presents itself as a cosmetic disturbance posing significant psychological distress and serves as a marker of the severity of skin thinning. In this study, we demonstrate that topical h-EGF diminishes the appearance of senile purpura by thickening skin and may help prevent the development of late stage dermatoporosis.

    Rhabdomyolysis associated with the use of pregabalin or azithromycin has been demonstrated to be a rare but potentially life-threatening adverse event. Here, we report an extremely rare case of rhabdomyolysis with purpura in a patient who had used pregabalin and azithromycin. We present the case of a 75-year-old woman with a history of fibromyalgia who was admitted with mild limb weakness and lower abdominal purpura. She was prescribed pregabalin (75mg, twice daily) for almost 3 months to treat chronic back pain. Her medical history revealed that 3days before admission, she began experiencing acute bronchitis and was treated with a single dose of azithromycin (500mg). She had developed rapid onset severe myalgia, mild whole body edema, muscle weakness leading to gait instability, abdominal purpura and tender purpura on the lower extremities. Laboratory values included a white blood cell count of 25,400/mL and a creatinine phosphokinase (CPK) concentration of 1250 IU/L. Based on these findings and the patient's clinical history, a diagnosis of pregabalin- and azithromycin-induced rhabdomyolysis was made. The long-term use of pregabalin and the initiation azithromycin therapy followed by a rapid onset of rhabdomyolysis is indicative of a drug interaction between pregabalin and azithromycin. We report an extremely rare case of rhabdomyolysis with purpura caused by a drug interaction between pregabalin and azithromycin. However, the mechanisms of the interactions between azithromycin on the pregabalin are still unknown. Copyright © 2016 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    Objective: To explore the role of IL-8 and IL-12 in the pathogenesis of anaphylactoid purpura (AP) and anaphylactoid purpura nephritis (APN). Methods: Serum IL-8 (with RIA) and IL-12 (with ELISA) levels were measured in 32 pediatric patients with anaphylactoid purpura (AP), 11 pediatric patients with anaphylactoid purpura nephritis (APN) and 15 controls. Results: During acute stage, serum IL-8 and IL-12 levels in both the AP and APN patients were significantly higher than those in controls and remained higher during convalescence. IL-8 and IL-12 levels were mutually positively correlated in acute stage. Conclusion: IL-8 and IL-12 participated in the pathogenesis of AP and APN. Theoretically, antagonist to those cytokines might be of clinical benefits. (authors)

    Abstract The severity of clinical features and the outcomes in previous series of patients reported with Henoch-Schönlein purpura (HSP) vary greatly, probably due to selection bias. To establish the actual clinical spectrum of HSP in all age groups using an unselected and wide series of patients diagnosed at a single center, we performed a retrospective review of 417 patients classified as having HSP according to the criteria proposed by Michel et al. Of 417 patients, 240 were male and 177 female, with a median age at the time of disease diagnosis of 7.5 years (interquartile range [IQR], 5.3–20.1 yr). Three-quarters of the patients were children or young people aged 20 years or younger (n = 315), and one-quarter were adults (n = 102). The most frequent precipitating events were a previous infection (38%), usually an upper respiratory tract infection, and/or drug intake (18.5%) shortly before the onset of the vasculitis. At disease onset the most common manifestations were skin lesions (55.9%), nephropathy (24%), gastrointestinal involvement (13.7%), joint symptoms (9.1%), and fever (6.2%). Cutaneous involvement occurring in all patients, mainly purpuric skin lesion, was the most common manifestation when the vasculitis was fully established, followed by gastrointestinal (64.5%), joint (63.1%), and renal involvement (41.2%). The main laboratory findings were leukocytosis (36.7%), anemia (8.9%), and increased serum IgA levels (31.7%). The most frequent therapies used were corticosteroids (35%), nonsteroidal antiinflammatory drugs (14%), and cytotoxic agents (5%). After a median follow-up of 12 months (IQR, 2–38 mo), complete recovery was observed in most cases (n = 346; 83.2%), while persistent, usually mild, nephropathy was observed in only 32 (7.7%) cases. Relapses were observed in almost a third of patients (n = 133; 31.9%). In conclusion, although HSP is a typical vasculitis affecting children and young people, it is not uncommon in adults. The prognosis is

    Full Text Available Background. Hemorrhagic vasculitis, or Henoch-Schönlein purpura (HSP, in children has its onset in the form of the articular syndrome in the vast number of patients, which is a part of the diagnostic criteria of this disease. The nature of the arthritis after the disease transformation from the juvenile HSP remains unexplored. In adulthood, articular patho­logy can manifest as migratory intermittent or chronic arthritis, but this information should be clarified. The objective was to study the clinical, X-ray and sonographic features of arti­cular syndrome course in patients with HSP and to evaluate the features of arthropathy in the presence of the disease that began in childhood and adulthood. Materials and methods. The study included 174 patients with HSP (83 % of men and 47 % of women. Childhood-onset vasculitis (on average in 12 years was diagnosed in 92 patients, and adulthood-onset (on avera­ge in 25 years — in 82; I, II and III degree of activity of the pathological process are established at a ratio of 1 : 2 : 2. Results. The joint affection is observed in every second patient with HPS, which is closely related to the patient’s age at the onset of the disease, duration and degree of the activity of pathological process, seropositivity by the high content of immunoglobulin A and rheumatoid factor. At that, clinical, radiological and sonographic nature of the articular syndrome’s course (involving the wrist, hip and sacroiliac joints, the development of aseptic osteonecrosis, bone erosion, meniscitis and intraarti­cular cartilage flaps depend on extraarticular manifestations of the di­sease (lesion of heart, kidney, pancreas, central nervous system. They are accompanied by an increased concentration in the blood of β2-microglobulin and circulating immune complexes that together with the values of fibrinogenemia have predictive value.

    Purpura is a common dermatologic manifestation in Sjögren syndrome (SS). When a patient presents with sicca symptoms, the diagnosis of SS is not difficult. Here, we reported a case of a 52-year-old Chinese woman who initially presented with nonpalpable purpura on both lower extremities, and these lesions had developed soon after prolonged sitting. In the past 2 years, she had repeated cutaneous nonpalpable purpura 4 times. She had no sicca symptoms, dry eyes, or dry mouth. Combining the laboratory findings, Schirmer test, and labial gland biopsy, primary SS was confirmed. The patient was placed on a trial of hydroxychloroquine (200 mg once daily). The purpura on both lower extremities had faded at the sixth day after onset and at the third day after hydroxychloroquine treatment. These case was not easy to diagnosis primary SS because she had no sicca symptoms. A patient with primary SS who initially presented with recurrent purpura associated with prolonged sitting. Prolonged sitting had been a possible aggravating factor for the cutaneous purpura of this patient with primary SS. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc.

    Previous in vitro studies demonstrated that thrombopoietin (TPO) acts on platelets to activate a variety of intracellular signaling pathways and to enhance platelet sensitivity to multiple agonists. Little is known, however, about whether TPO exerts prothrombotic effects in vivo. The aim of this study was to examine the effects of pegylated recombinant human megakaryocyte growth and development factor (PEG-rHuMGDF), a pegylated N-terminal domain of human TPO, in a rat model of venous thrombosis. A microthrombus was photochemically induced on the vessel wall of a mesenteric venule, but the vessel was not occluded by it. A single intravenous injection of PEG-rHuMGDF (3 microg kg(-1)) after the thrombus generation into normal rats enhanced the thrombus size, resulting in transient thrombotic occlusion in the majority of rats. Stimulatory effects on thrombus growth were also observed following administration of glycosylated recombinant human full-length TPO (6 microg kg(-1)). In rats rendered thrombocytopenic by total body irradiation, however, PEG-rHuMGDF, even at 300 microg kg(-1), did not induce a significant increase in thrombus size or thrombotic occlusion. Platelets from thrombocytopenic rats had decreased surface levels of c-Mpl and decreased sensitivity to PEG-rHuMGDF in an in vitro aggregation response. Thus, decreased prothrombotic effects of PEG-rHuMGDF in thrombocytopenic rats might be the result not only of low platelet counts but also of decreased platelet reactivity to PEG-rHuMGDF. These results indicate that PEG-rHuMGDF has little effect on venous thrombus formation in thrombocytopenic states associated with high endogenous TPO levels.

    Petechiae and purpura are among the most alarming findings a pediatrician will commonly observe in the office. Severity of illness can range from a temper tantrum, to common viral infections, to the most deadly infections and diseases. To avoid many of the pitfalls in diagnosis, practitioners will need to be thorough in history taking, assessing fever and immunization status, and physical examination. In addition, a few simple laboratory tests will usually be needed and possibly a manual differential. Copyright 2014, SLACK Incorporated.

    The main aim of this study was to evaluate the relationship between obesity and renal involvement in children with Henoch-Schönlein purpura (HSP). A retrospective study of 141 pediatric patients with HSP was conducted in our hospital. The clinical data of all patients were collected from the electronic medical record management system from January 2010 to June 2014. The possible risk factors of renal involvement, especially obesity, were analyzed using univariate and multivariate analyses. Renal involvement occurred in 45/141 of the patients. A univariate analysis showed that an age more than 7 years at onset, persistent purpura, obesity, time from symptoms onset to diagnosis more than 14 days, and decreased C3 all increased the risk of renal involvement in HSP. The forward stepwise logistic regression analysis indicated obesity (odds ratio (OR) 4.43, 95 % confidence interval (CI) 1.896 to 10.358), age more than 7 years at onset (OR 2.81, 95 % CI 1.142 to 6.907), and persistent purpura (OR 2.57, 95 % CI 1.119 to 5.909) were independent risk factors for renal involvement. Our results show that obesity can increase the hazard of renal involvement in children with HSP and reconfirm that older age at onset and persistent purpura are the independent risk factors for renal involvement. • There have been some reports that obesity was associated with the development of renal injury. • It is not clear whether obesity can increase the risk of renal involvement in children with HSP. What is New: • The main finding of this study is that obesity can increase the hazard of renal involvement in children with HSP.

    The most feared bleeding complication in fetal and neonatal alloimmune thrombocytopenia (FNAIT) is an intracranial hemorrhage (ICH). However, FNAIT may also lead to other severe bleeding problems. The aim was to analyze this spectrum and evaluate the occurrence of severe hemorrhages other than ICH in fetuses or neonates with FNAIT. A retrospective chart analysis of cases of FNAIT presenting with severe bleeding complications other than ICH at our institution from 1990 to 2015 was conducted. Additionally, a review of the literature was performed to identify case reports and case series on FNAIT presenting with extracranial hemorrhage. Of 25 fetuses or neonates with severe bleeding due to FNAIT, three had isolated severe internal organ hemorrhage other than ICH, two pulmonary hemorrhages and one gastrointestinal hemorrhage. Two of these three neonates died due to this bleeding. Eighteen cases of extracranial bleeding complications as a first presentation of FNAIT were found in the literature, including ocular, gastrointestinal, spinal cord, pulmonary, renal, subgaleal, and genitourinary hemorrhages. Bleeding complications other than ICH may be more extensive, and the presentation of FNAIT may have a greater spectrum than previously described. A high index of suspicion on the possible diagnosis of FNAIT with any bleeding complication in a fetus or neonate may enable adequate diagnostics, adequate treatment, and appropriate follow-up in future pregnancies, as is especially relevant for FNAIT. © 2016 AABB.

    Introduction The objective of the analysis was to examine the epidemiological aspects of maternal alloimmunization and to determine the most common antibody specificities resulting in hemolytic disease of the newborn (HDN). Materials and Methods The retrospective epidemiological study encompasses all pregnant women who underwent immunohematological screening and the newborn treated for HDN in the period from 2000 to 2013 in the Herzegovina region. Results The indirect Coombs test (ICT) detected antibodies against antigens in 384 (2.4%) pregnant women of the 18 800 who were tested at the Department of Transfusion Medicine. The direct Coombs test (DCT) detected antibodies against antigens in 160 (0.8%) newborn treated for HDN. The results of our 13-year study, in which 60% of the pregnant women had non-RhD antibodies, confirms this finding. Conclusion However, we have reached the 21st century and the burden of alloimmunisation in pregnancy is still on our backs. The problem of immunization and HDN is still present in our region, which is a neonatal and public health problem. PMID:28729746

    Neonatal alloimmune thrombocytopenia (NAIT) is the most common cause of severe thrombocytopenia and intracranial hemorrhage in the perinatal period. While the gold standard for making a diagnosis of NAIT is detection of a human platelet antigen (HPA)-specific antibody in maternal serum, together with identifying an incompatibility between the parents for the cognate HPA antigen, platelet genotyping is the gold standard method for HPA typing. Platelet genotyping is critical in screening at-risk fetuses for the presence ofthe HPA corresponding to the maternal antibody. In addition, platelet genotyping may play a role in population screening to identify women at risk for sensitization, and thus, fetuses at risk for NAIT. The most commonly used methods of platelet genotyping are sequence-specific primer-polymerase chain reaction (PCR-SSP), restriction fragment length polymorphism-PCR (PCR-RFLP), and TaqMan real-time PCR. PCR-SSP and PCR-RFLP are relatively inexpensive and technically simple methods, but they are not easily automated and require expertise for reliable interpretation of results. Newer methods that allow for multiplexing, automation, and easily interpretable results, such as bead arrays, are currently in development and available for research purposes.

    Association between endothelial nitric oxide synthase (eNOS) gene polymorphism and Henoch-Schönlein purpura (HSP)/Henoch-Schönlein purpura nephritis (HSPN) risk is still controversial. A meta-analysis was performed to evaluate the association between eNOS gene polymorphism and HSP/HSPN susceptibility. A predefined literature search and selection of eligible relevant studies were performed to collect data from electronic database. Three articles were identified for the analysis of association between eNOS gene polymorphism and HSPN/HSP risk. eNOS G894T gene polymorphism was not associated with HSPN susceptibility and the risk of patients with HSP developing into HSPN. Interestingly, eNOS G894T T allele and GG genotype were associated with HSP susceptibility, but not the TT genotype. eNOS T786C TT genotype was associated with HSPN susceptibility, but not C allele and CC genotype. Furthermore, eNOS T786C gene polymorphism was not associated with HSP risk and the risk of patients with HSP developing into HSPN. In conclusion, eNOS T786C TT genotype was associated with and eNOS G894T T allele and GG genotype were associated with HSP susceptibility. However, more studies should be performed in the future.

    Anaphylactoid purpura, also known as Henoch-Schönleinpurpura (HSP), is an IgA-mediated vasculitis that tends to be a benign disease of childhood. Up to 50% of cases are preceded by an upper tract respiratory infection caused by group-A beta-hemolytic streptococcus and present with the common tetrad of abdominal pain, arthritis, purpuric rash, and renal involvement. The majority of patients recover completely. Here we document a rare case of anaphylactoid purpura which manifested with skin lesions in the form of palpable purpura following about of acute gastroenteritis with severe dehydration; it was treated with a short regimen of steroid therapy, which resulted in the complete remission of the disease. We conclude that prompt diagnosis and multidisciplinary intervention will lead to appropriate management-consisting of the installation of early short-course steroid therapy and thus, prevent further complications and the recurrence of the disease.

    Despite some unresolved problems that may be associated with platelet transfusion, such as alloimmunisation, refractoriness, bacterial contamination, and the potential side effects related to the development of some biological response modifiers during storage, platelet therapy remains the most effective treatment for the management and prevention of severe thrombocytopenia and hemorrhage [Seghatchian J, Snyder EL, Krailadsiri P, editors. Platelet therapy: current status and future trends. Amsterdam, The Netherlands: Elsevier; 2000]. This appears to be particularly the case in neonatal alloimmune thrombocytopenia (NAIT), which arises due to an incompatibility of the platelet specific antigens between the pregnant mother and her baby. Over 80% of severe NAIT cases in the Caucasian population occur when the mother and baby differ in their HPA-1 epitope (HPA-1a negative and positive respectively) leading, in 10% of cases, to the production of anti-HPA-1a which can cross the placenta and cause NAIT in utero or post-partum. Anti-HPA-5b is the second most cause of NAIT, although severe cases occur only after the first pregnancy. Clinical manifestations of NAIT vary from mild (petechia and bruises) to severe (intracranial haemorrhage with possible death or life long morbidity). A recent study in Scotland indicated that the cost per case of severe NAIT detected during screening of pregnant women, where anti-HPA-1a is detected for the first time, would amount to $98,771 [Turner M, Bessos H, et al.

    UV-B irradiation of platelet concentrates (PC) has been tried in several institutes to inactivate leukocytes in PC and prevent alloimmunization on platelet transfusion. However, the mechanism of inactivation of leukocytes contaminating PC has not been fully understood. It is known that UV-B light is absorbed by photosensitizers in cells and produces active oxygen and radicals, such as singlet oxygen, superioxide anions and hydroxyl radicals. These active oxygen or radicals should injure cellular components and this could cause the suppression of cellular functions. In this study, we investigated the relationships among UV-B irradiation, free radical generation and leukocyte inactivation. We found the evidence that active oxygen and radicals were produced in peripheral blood mononuclear cells by UV-B irradiation. UV-B irradiation suppressed the stimulatory function of leukocytes in a mixed lymphocyte reaction (MLR), and the suppression depended on the dosage of UV-B. Even a low dosage of UV-B, 10 J/m 2 , could inhibit the MLR if the irradiated cells were incubated at 37degC for 24 hours before co-culture with responder cells. Treatments of cells with the exogenous singlet oxygen or superoxide anions also caused suppression of the stimulatory function in the MLR, inhibition of capping formation of HLA-DR antigens, and an increase of intracellular free Ca 2+ levels as did the UV-B treatment. These results indicate that the active oxygen or radicals generated in UV-B-irradiated leukocytes could be one of the causes of leukocyte inactivation. (author0

  1. Henoch-Schönlein purpura without systemic involvement beginning with acute scrotum and mimicking torsion of testis

    Full Text Available Henoch-Schönlein purpura (HSP is the most common systemic vasculitis in children. Typical presentations of HSP are palpable purpura of the small vessels in the hips and lower limbs, abdominal pain, arthritis, and hematuria. Scrotal involvement manifested by the presence of scrotal pain and swelling during the course of the disease is rarely seen. HSP without systemic involvement with acute scrotum mimicking testicular torsion is even rare in the medical literature. In most cases, patients with this disease achieve complete recovery. Herein, we report an interesting HSP case with skin symptoms but without systemic involvement and then progression to acute scrotum resembling torsion of testis.

    INTRODUCTION: The gastrointestinal manifestations of Henoch-Schonlein purpura (HSP) are well characterised, but their recognition can be difficult when they occur in isolation. Furthermore, HSP can run a more serious course in adults, compared to children, in whom the disease usually occurs. MATERIALS AND METHODS: We describe two cases that illustrate the challenges of HSP with mesenteric vasculitis and the outcome in adults. CONCLUSION: Although self-limiting in most patients, the outcome of HSP in adults can be far from benign and even fatal.

    Full Text Available Helicobacter pylori (H. pylori are one of the most common bacterial infections, seen in humans, worldwide and their possible relationships to different diseases are a focus of attention nowadays. H. pylori may cause some extra intestinal manifestations some of which are dermatological conditions, including Henoch-Schönlein purpura (HSP, chronic urticaria and atopic dermatitis. We describe a 49-year-old man who presented with HSP triggered by gastric H. pylori infection. Treatment of H. Pylori infection was accompanied by prompt resolution of the gastrointestinal manifestations and purpuric rashes. These findings suggest a causative role for H. pylori in the occurrence of HSP.

    Even though prompt diagnosis and treatment of purpura fulminans (PF) is essential to reduce mortality, early administration of antibiotics may preclude identification of the causative agent by standard bacterial cultures and thus render definitive diagnosis impossible. Here we present a case of an infant with PF and negative bacterial cultures for whom polymerase chain reaction (PCR) analysis of a cutaneous biopsy specimen obtained 4 days after initiation of antibiotics identified the genomic sequence of Neisseria meningitidis genogroup C. When bacterial cultures fail to provide useful information, PCR of skin biopsy specimens can be a valuable diagnostic tool in PF. © 2013 Wiley Periodicals, Inc.

    Human immunodeficiency virus (HIV) infection is growing medical concern worldwide. There are many types of glomerulonephritis which are associated with HIV infection. We report a case of a 53-year-old Korean man with an HIV infection, who was developed nephritic range proteinuria and purpura with elevated IgA level rasing a possibility of Henoch-Schölein Purpura (H-S purpura). However, renal biopsy showed "lupus-like feature" glomerulonephritis without clinical or serologic evidence of systemic lupus erythematosus. Although baseline renal function was maintained without further need for maintenance dialysis following anti-retroviral therapy (ART) and steroid, patient died from uncontrolled gastrointestinal bleeding.

    The optimal dose of UV-B radiation for prevention of in vivo alloimmunization (AI) against major histocompatibility complex (MHC) antigens was investigated in a murine transfusion model. Two groups with five C57BL/6 mice (H-2 b ) each were transfused at weekly intervals with 1 x 10 5 or 1 x 10 6 DBA/2 (H-2 d ) leucocytes. Both suspensions induced anti-H-2 d antibodies in all mice after the second transfusion. The minimal UV-B dose required for abolition of alloreactivity in the mixed leucocyte reaction (MLR) was 0.6 J/cm 2 . This dose completely prevented the onset of MHC-AI in all five mice transfused with six suspensions containing 1 x 10 5 leucocytes. In contrast, suspensions with 1 x 10 6 leucocytes and exposed to 0.6 J/cm 2 induced immunization in 4/5 mice. Further increase of the dose to 1.8 or 5.4 J/cm 2 did not prevent the onset of MHC-AI. We conclude that the number of leucocytes per transfusion determines the efficacy of UV irradiation for the prevention of MHC-AI. For UV irradiation of human platelet concentrates (PCs) we propose to reduce the number of leucocytes by centrifugation prior to UV exposure. UV-B irradiation of PCs with high numbers of leucocytes may not be effective for prevention of alloimmunization. (Author)

    Self harm is a great diagnostic and treatment challenge. In addition, psychocutaneous conditions are rare in the pediatric population and may therefore be misdiagnosed. Dermatitis artefacta is a psychocutaneous syndrome, which is a subgroup of the general spectrum of self-inflicted skin lesions. Dermatitis artefacta encompasses an array of different clinical manifestations, including purpura. Factitious purpura has rarely been reported in children. Case report and review of the literature. We describe two Caucasian patients (9-year-old boy and 10-year-old girl) with striking purpuric lesions diagnosed as factitious purpura. The clinical lesions were similar, but the underlying psychological problems differed significantly (depression and stress). The current state of knowledge of dermatitis artefacta in children and adolescents was reviewed. The presence of purpura in children and adolescents typically causes extensive intervention programs due to the possible serious pathological consequences. The two cases demonstrate a need for a high degree of attention to psychological disturbances, lesional evolution, and distribution once the suspicion is established. © 2014 The International Society of Dermatology.

    We present a case of a 14-year-old girl who had a severe form of granulomatosis with polyangiitis (GPA) with extensive dermatological involvement, whose initial presentation was nonspecific leading to diagnostic confusion and initial consideration of infectious and other vasculitis causes. The patient presented with fever, congestion, malaise, and sinus pain. She was diagnosed with bacterial sinusitis and treated with antibiotics. Within weeks, she developed abdominal pain, hematuria, migratory arthritis, and palpable purpura and was diagnosed with Henoch-Schonlein purpura. She went on to develop hemoptysis and progression of the rash into erosive bullae. Investigations revealed that she was ANCA positive and had pauci-immune glomerulonephritis. Given her upper airway, pulmonary and renal involvement, and antineutrophil cytoplasmic antibodies positivity, a definitive diagnosis of a severe form of GPA was made. GPA is a chronic relapsing, life threatening vasculitis that predominantly affects small vessels. Our case demonstrates that GPA can present initially with nonspecific symptoms, including extensive dermatological involvement, leading to diagnostic confusion, and delays in treatment. In the case of a severe peripheral rash in the juvenile population and/or resistant upper airway symptoms, it is vital to consider a diagnosis of GPA to avoid serious organ or life threatening consequences.

    Henoch-Schönlein purpura is a common vasculitis of childhood. The present study, comprising 74 children enrolled during a 9-year period, aimed to delineate the clinical spectrum and the long term follow-up of the disease. Patients were diagnosed strictly on the criteria established by the American College of Rheumatology. The diagnosis was further strengthened by a skin biopsy performed in more than half of cases (42/74), which revealed leukocytoclastic vasculitis in all patients, whereas IgA deposits were found in 37/42 children. There was a predominance of boys (41 males), and the mean age of study population was 5.2 +/- 2.54 years. Palpable purpura was identified in 73/74 children, whereas transient arthritis manifested in 68/74 children. Gastrointestinal blood loss was elicited in 30 children, 11 of whom had also renal involvement. The latter was seen in 19/74 (25.7%) children, and in the long term follow-up (extended to 2004, from 4-12 years, mean duration 7.3 years), 2 children remained with persistent occult hematuria. Relapses occurred in 49 children (66%), and half of them experienced more than 1 recurrence. Arthritis was less common in the relapsed episodes, and this difference was statistically significant (P period. Recurrences often differ to some extent from the initial episode with arthritis being less common with relapses.

    Primary immune thrombocytopenia (ITP) - also called idiopathic thrombocytopenic purpura or immune thrombocytopenic purpura - is an acquired thrombocytopenia caused by autoantibodies against platelet antigens. It is one of the more common causes of thrombocytopenia in otherwise asymptomatic adults. Rocky Mountain spotted fever (RMSF) is a potentially lethal, but curable, tick-borne disease. We present a case of ITP that was triggered by RMSF.

    A 37-year-old pregnant woman developed purpura which was subsequently diagnosed as Henoch-Schönlein purpura (HSP). After childbirth, the patient developed proteinuria and hematuria. Further examination revealed that the HSP nephritis (HSPN) was associated with anti-threonyl-tRNA synthetase anti-synthetase syndrome. The onset of HSPN during pregnancy or after childbirth is rare. Moreover, to our knowledge, this is the first case to describe renal involvement in anti-synthetase syndrome.

    Senile purpura is a common, chronic skin condition affecting more than 10 percent of individuals over the age of 50. Despite being a benign condition, the continual development of purpura lesions in afflicted patients is frequently a source of significant visual and social concern. To date, there are no known effective treatments for this condition. To evaluate the efficacy of a novel nutraceutical citrus bioflavonoid blend in improving the skin's appearance in patients with senile purpura. A six-week, randomized, multicenter, placebo-controlled, double-blind study was conducted to determine whether a uniquely formulated, oral citrus bioflavonoid supplement could treat active lesions of senile purpura while preventing new lesions from arising. Seventy patients with senile purpura were enrolled and 67 completed the study. Subjects were randomized into two groups receiving either a citrus bioflavonoid blend or placebo medication, which was taken orally twice daily for six weeks. Clinical evaluations were performed by blinded investigators at two locations. A statistically significant reduction in the number of new purpura lesions in the skin area undergoing clinical study was documented. At the end of six weeks, the citrus bioflavonoid blend treated group showed a 50 percent reduction in purpura lesions from baseline. Patient self-assessment of the effectiveness of the medication echoed the results of an investigator global assessment with a statistically significant improvement in the skin's appearance noted by the patients receiving the active medication. No adverse effects were noted by either the patients or investigators. This new treatment appears to both safely and effectively diminish skin bruising in patients with senile purpura.

    Full Text Available Fetal/neonatal alloimmune thrombocytopenia (FNAIT can be a cause of severe fetal thrombocytopenia, with the common presentation being intracranial hemorrhage in the fetus, usually in the third trimester. A very unusual case of fetal anemia progressed to hydrops. This was further complicated by maternal Mirror syndrome and human chorionic gonadotropin–induced thyrotoxicosis. Without knowledge of etiology, and possibly due to associated cardiac dysfunction, fetal transfusion resulted in fetal demise. Subsequent testing revealed FNAIT as the cause of severe hemorrhagic anemia. In cases with fetal anemia without presence of red blood cell antibodies, FNAIT must be ruled out as a cause prior to performing fetal transfusion. Fetal heart may adapt differently to acute hemorrhagic anemia compared with a more subacute hemolytic anemia.

    Background Onset of Henoch-Schönlein purpura (HSP) in middle age is uncommon, and adults with renal or gastrointestinal involvement present with more severe disease than do similar pediatric patients. Case presentation We present the case of a 69-year-old male with HSP who, after treatment with steroids, cyclophosphamide, and continuous intravenous prostaglandin E1 (PGE1), died as a result of severe gastrointestinal involvement with non-occlusive mesenteric ischemia (NOMI). Vascular narrowing associated with the NOMI improved after catheter injection of PGE1 and prednisolone, but the patient died of bleeding from an exposed small vessel. At autopsy there was no active vasculitis in the jejunal submucosa. Conclusion Treatment with PGE1 and prednisolone might improve small-vessel vasculitis associated with NOMI. PMID:23343144

    Infliximab (IFX) is an anti-tumor necrosis factor chimeric antibody that is effective for treatment of autoimmune disorders such as Crohn's disease and ulcerative colitis (UC). IFX is well tolerated with a low incidence of adverse effects such as infections, skin reactions, autoimmunity, and malignancy. Dermatological manifestations can appear as infusion reaction, vasculitis, cutaneous infections, psoriasis, eczema, and skin cancer. Here, we present an unusual case of extensive and sporadic subcutaneous ecchymosis in a 69-year-old woman with severe UC, partial colectomy and cecostomy, following her initial dose of IFX. The reaction occurred during infliximab infusion, and withdrawal of IFX led to gradual alleviation of her symptoms. We concluded that Henoch-Schönlein purpura, a kind of leukocytoclastic vasculitis, might have contributed to the development of the bruising. Although the precise mechanisms of the vasculitis are still controversial, such a case highlights the importance of subcutaneous adverse effects in the management of UC with IFX.

    Full Text Available Streptococcus pneumoniae is an invasive organism that causes a wide range of common diseases, including sinusitis, acute otitis media, and pneumonia. Splenic abscesses and purpura fulminans (PF are rare complications of pneumococcal disease. Splenic abscesses caused by S pneumoniae have only been reported in the adult literature. PF has been described in the pediatric population as a rare complication in patients with invasive pneumococcal disease (IPD with and without underlying immunological disorders such as asplenia. Here, we report a patient with IPD complicated by splenic abscesses and PF. Our patient initially presented with bacteremia, septic shock, and disseminated intravascular coagulation. She subsequently developed PF and splenic abscesses. She survived her illness after receiving a total of 8 weeks of antibiotic therapy. This case highlights 2 rare complications of IPD and demonstrates the need to keep pneumococcal disease in the differential diagnosis even in children whose vaccination status is up to date.

    Full Text Available Idiopathic thrombocytopaenic purpura (ITP patients are at high risk for complications during and after cardiac surgeries involving cardiopulmonary bypass. The main clinical problem of primary ITP is an increased risk of bleeding although bleeding may not always be present. More recently, thrombosis has become appreciated as another potential complication of the procedure. We report a 22-year-old female patient with ITP with bicuspid aortic valve and splenomegaly, who underwent uncomplicated aortic valve replacement and splenectomy simultaneously. She was readmitted with chest pain due to coronary thrombosis following splenectomy which made the management difficult. We describe our experience in managing this patient who presented with thrombotic complication rather than bleeding in post-operative period and the challenges met in maintaining appropriate anticoagulation for aortic valve replacement as well as thrombosis, post-splenectomy

A total of 96 children who presented at Aichi Children's Health and Medical Center and were diagnosed as having HSP were evaluated for infectious foci in the ear, nose, throat, and oral cavities. Seventy-one of 96 children (74.0% had some type of infectious lesion, such as sinusitis or tonsillitis, and the prevalence of sinusitis was the highest (51 cases, 53.7%. In 44 HSP patients without renal involvement at the first examination, the incidence of nephritis was lower (13.6% than in previous reports (17–54% due to our aggressive intervention for infectious foci.

    Full Text Available Background: There are several methods for counting platelets, of which the international flow reference method (IRM is considered to be the gold standard. We compared the platelet count given by this method to the count given by automated analyzers using other methods, such as optical fluorescence and impedance. Aims: The aim of this study is to compare the platelet counts obtained by Sysmex XE 2100 by Impedance (Sysmex-I, optical florescence (Sysmex-O and reported (Sysmex-R based on the switching algorithm and LH-750 by Impedance (LH-750 with the IRM in thrombocytopenic blood samples. To calculate the sensitivity, specificity, positive predictive value (PPV and negative predictive value (NPV of various technologies at the clinically relevant transfusion thresholds of 10 × 10 9 /l and 20 × 10 9 /l. Materials and Methods: A total of 118 blood samples with platelet count of <50 × 10 9 /l were selected for the study. Platelet counts of all samples were analyzed by all methods using the Sysmex analyzer, LH-750 and IRM in parallel within 6 h of collection. Statistical Analysis Used: Pearson correlation, bland Altman analysis, sensitivity and specificity, PPV and NPV. Results and Conclusions: Sysmex-R had the least Bias and 95% limits of agreement (95%LA range and thus correlated best with IRM values. LH-750 had a higher Bias compared to Sysmex-O and Sysmex-R, but a strikingly similar 95% LA ensures similar results in all three methods. In fact, in the oncology subset, it had the narrowest 95% LA, which made it the best performer in this subgroup. Of the three Sysmex results, Sysmex-I had the highest bias, widest 95% LA and highest potential risk of over transfusion. Hence, Sysmex-R and LH-750 were found to be reliable tools for estimation of platelet count in thrombocytopenic patients.

    Henoch-Schönlein purpura is the most common vasculitis in children. Its long-term prognosis depends on renal involvement. The management of Henoch-Schönlein purpura nephritis (HSPN) remains controversial. This study reports the prognosis of children with HSPN presenting with class 2 International Study of Kidney Disease in Children (ISKDC) nephritis. All children with HSPN class 2 diagnosed between 1995 and 2015 in four pediatric nephrology centers were included, and clinical and biological data were collected from the medical files. The primary endpoint was proteinuria remission defined as a proteinuria 3 g/L, 52% proteinuria between 1 and 3 g/L, and 18% proteinuria <1 g/L. Forty-seven percent of patients received orally treatment with steroids alone, 37% received methylprednisolone pulses followed by steroids orally, 18% received no steroids. Although 85% reached remission during follow-up, 12% did not maintain complete remission over time so that only 75% remained in complete remission by the end of the follow-up. Univariate analysis found a higher likelihood of remission in patients with higher proteinuria at disease onset (p = 0.009). This trend was not found in the multivariate analysis after adjusting for treatments, as patients with higher proteinuria were most often treated with steroids. Our study shows that one fourth of patients with HSPN class 2 remain proteinuric and thus carry the risk of developing chronic kidney disease over the long term. This finding, together with the better outcome of patients treated with steroids, is in favor of using high-dose steroids orally or IV in these patients.

    Full Text Available Henoch Schonlein Purpura (HSP is the commonest systemic vasculitis of childhood typically presenting with a palpable purpuric rash and frequently involving the renal system. We are the first group to clinically assess, critically analyse and subsequently revise a nurse led monitoring pathway for this condition.A cohort of 102 children presenting with HSP to a secondary/tertiary level UK paediatric hospital over a five year period, were monitored using a nurse led care pathway. Using this cohort, the incidence (6.21 cases per 100,000 children per year and natural disease course of HSP nephritis (46% initial renal inflammation; 9% subsequent renal referral; 1% renal biopsy and immunosuppression was determined. Older patients were at higher risk of requiring a renal referral (renal referral 12.3 (8.4-13.5 years vs. normal outcome 6.0 (3.7-8.5 years; p<0.01. A normal urinalysis on day 7 had a 97% (confidence interval 90 to 99% negative predictive value in predicting a normal renal outcome.Using this data and existing literature base, The Alder Hey Henoch Schonlein Purpura Pathway was developed, a revised pathway for the screening of poor renal outcome in HSP. This is based on a six-month monitoring period for all patients presenting with HSP, which importantly prioritises patients according to the urine findings on day 7 and thus intensively monitors those at higher risk of developing nephritis. The pathway could be easily adapted for use in different settings and resources.The introduction of a standardised pathway for the monitoring of HSP will facilitate the implementation of disease registries to further our understanding of the condition and permit future clinical trials.

    Long-term graft deterioration remains a major obstacle in the success of pancreatic islet transplantation (PITx). Antigen-independent inflammatory and innate immune responses strengthen subsequent antigen-dependent immunity; further, activation of nuclear factor (NF)-κB plays a key role during these responses. In this study, we tested our hypothesis that, by the inhibition of NF-κB activation, the suppression of these early responses after PITx could facilitate graft acceptance. Full major histocompatibility complex (MHC)-mismatched BALB/c (H-2) mice islets were transplanted into streptozotocin-induced diabetic C57BL/6 (B6: H-2) mice. The NF-κB inhibitor dehydroxymethylepoxyquinomicin (DHMEQ) was administered for either 3 or 14 days after PITx. To some PITx recipients, tacrolimus was also administered. Islet allograft survival, alloimmune responses, and in vitro effects of DHMEQ on dendritic cells (DCs) were assessed. With a vehicle treatment, 600 islet allografts were promptly rejected after PITx. In contrast, 3-day treatment with DHMEQ, followed by 2-week treatment with tacrolimus, allowed permanent acceptance of islet allografts. The endogenous danger-signaling molecule high mobility group complex 1 (HMGB1) was elevated in sera shortly after PITx, whereas DHMEQ administration abolished this elevation. DHMEQ suppressed HMGB1-driven cellular activation and proinflammatory cytokine secretion in mouse bone marrow-derived DCs and significantly reduced the capacity of DCs to prime allogeneic T-cell proliferation in vitro. Finally, the DHMEQ plus tacrolimus regimen reverted the diabetic state with only 300 islet allografts. Inhibition of NF-κB activation by DHMEQ shortly after PITx suppresses HMGB1, which activates DCs and strengthens the magnitude of alloimmune responses; this permits long-term islet allograft acceptance, even in case of fewer islet allografts.

    The Henoch-Schönlein purpura (HSP) is a small vessel vasculitis with IgA immune complex deposition. The presentation in adults is rare and severe. Reported cases of HSP in patients infected with HIV are scarce. Neutrophil cytoplasmic antibodies (ANCA) are commonly found in other systemic vasculitis, but rarely in HSP and even more unusual the perinuclear pattern. Beside small vessel vasculitis, positivity of ANCA can be detected in a number of different pathological conditions in association with infectious processes, including HIV, or cocaine use, and especially the pattern of ANCA-p, associated with drugs, inflammatory bowel or autoimmune diseases. We report the case of a 35 years old man with toxic habits (cocaine, marijuana) who consulted for abdominal pain, hematochezia and purpura on lower extremities, and later fever, joint pain and progression of purpura associated with nephritic syndrome and ANCA-p (+). During hospitalization HIV infection was detected. Renal biopsy showed IgA nephropathy with favorable response to corticosteroid and antiproteinuric treatment. The communication of the case is due to the rarity of the presentation and therapeutic diagnostic challenge. It remains to elucidate the role of ANCA in the pathogenesis and management of adult PSH.

    A 59-year-old male presented with methicillin-resistant Staphylococcus aureus bacteraemia from a prostatic abscess and was treated with vancomycin. Two weeks into his treatment course, he developed severe joint pains, abdominal pain with bloody, mucinous stools and a diffuse palpable purpuric rash on his extremities. Biopsy of the rash showed IgA immune-complex deposition consistent with Henoch-Schönlein purpura. After treatment with glucocorticoids, his symptoms resolved completely. Vancomycin is an extremely commonly used antibiotic with certain well-known adverse effects. Henoch-Schönlein purpura, a vasculitis involving abdominal pain, arthralgias and palpable purpura, is a much less common side effect, as seen in this patient. Given that vancomycin is widely used internationally, clinicians should be aware of the risks entailed by its use. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Henoch-Schönlein purpura (HSP) is a small vessel IgA-predominant vasculitis. To describe adult patients with HSP and determine if the distribution of skin lesions (ie, purpura above the waist or purpura below the waist only), is a predictor of significant renal involvement at the time of the skin biopsy and the months following. A retrospective study on renal function from 72 adult patients with skin-biopsy proven HSP. Longitudinal renal data were analyzed after HSP diagnosis by using baseline renal function for comparison. Statistical analysis adjusted for sex, age, and baseline creatinine revealed a trend between HSP lesions only on the upper and lower extremities and long-term renal involvement (4.767, P = .067). Moreover, in another analysis adjusted for age and baseline creatinine, lesions located only on the upper and lower extremities significantly increased the odds of having long-term significant renal involvement (6.55, P = .049) in men. This retrospective study used patient information that was subject to selection bias. In patients with HSP, skin lesion distribution on the extremities might be predictive of significant long-term renal involvement and might be critical for risk stratification and development of personalized diagnostics and therapeutics.

CONCLUSÕES: o CHE isolado foi uma manifestação grave em pacientes internados com LESJ, habitualmente associado a uma doença ativa e sistêmica.OBJECTIVE: to evaluate the hematological involvement (HI in hospitalized patients with juvenile systemic lupus erythematosus (JSLE. METHODS: from 1994 to 2005, 195 admissions occurred in 77 JSLE patients (American College of Rheumatology criteria and were followed by the Pediatric Rheumatology Unit of the Instituto da Criança - University of São Paulo. These admissions were evaluated according to the presence of HI at onset or during the evolution of the disease: autoimmune hemolytic anemia (AHA or thrombocytopenic purpura. All patients performed at least two complete blood counts. AHA was defined by a fall in hemoglobin levels (beyond 2 g/dl, reticulocytosis, increase in lactate dehydrogenase (LDH and indirect bilirubin levels, and a positive Coombs test. The hematologic manifestations associated with infection, neoplasia and aplastic anemia were excluded. RESULTS: HI occurred in 14 patients (18.9%, with 15 admissions. Among these patients, 11 were female, 7 had trombocytopenic purpura, 5 AHA and 2 Evans syndrome. HI as onset and single manifestation of JSLE was observed in three patients. All the patients with trombocytopenic purpura presented cutaneous bleeding (petechia and/or ecchymosis. All had disease activity and simultaneously presented other manifestations of JSLE, particularly nephritis and vasculitis. Initially, all patients received pulsetherapy with methylprednisolone and prednisone later. In three patients the treatment aimed predominantly the control of hematologic manifestations, with intravenous gammaglobulin. The most used immunossupressive therapies were intravenous cyclophosphamide, cyclosporine and azathioprine. One patient died of central nervous system bleeding. No patient needed splenectomy. CONCLUSIONS: isolated HI was a severe manifestation in hospitalized patients with JSLE, generally

    To explore a panel of serum biomarkers for laboratory diagnosis of pediatric Henoch-Schönlein purpura (HSP). The blood white blood cells (WBC) and serum levels of serum amyloid A (SAA), interleukin 6 (IL-6), immunoglobulin A (IgA), immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin E (IgE), C-reactive protein (CRP), complement component 3 (C3), complement component 4 (C4), and ASO (anti-streptolysin O) were detected in 127 patients with Henoch-Schonlein purpura (HSP), 110 cases of septicemia patients, and 121 healthy volunteers. The diagnostic ability of biomarkers selected from HSP and septicemia patients was analyzed by ROC curve. By designing the calculation model, the biomarker index was calculated for laboratory diagnosis of HSP and differential diagnosis between HSP and septicemia. The levels of serum WBC, CRP, IL-6 and SAA in the septicemia patients were significantly higher than those in the control group (p<0.05). Compared with the healthy individuals, serum levels of WBC, CRP, IL-6, SAA, IgA and IgM were significantly increased in patients with HSP (p<0.05). The area under the curve (AUC) of SAA, IgA, IgM, WBC, IL-6, and CRP in the patients with HSP was 0.964, 0.855, 0.849, 0.787, 0.765, and 0.622, respectively. The values of SAA, IgA, IgM, WBC, IL-6, and CRP in septicemia patients were 0.700, 0.428, 0.689, 0.682, 0.891, and 0.853, respectively. Biomarker index=SAA+IgA/4000+IgM/4000×0.4CRPmean valueCRPi . The biomarker index in HSP patients was significantly higher than that of the healthy controls. However, the biomarker index in septicemia patients was significantly lower than the control. The biomarker index of HSP patients is higher than that of the control group. While in the infectious disease represented by septicemia, it is decreased. The detection of biomarker index could exclude the interference of infection as the auxiliary examination to HSP patients. Copyright © 2017 The Canadian Society of Clinical Chemists. Published by

  10. CD4 Depletion or CD40L Blockade Results in Antigen-Specific Tolerance in a Red Blood Cell Alloimmunization Model

    Full Text Available Approximately 3–10% of human red blood cell (RBC transfusion recipients form alloantibodies to non-self, non-ABO blood group antigens expressed on donor RBCs, with these alloantibodies having the potential to be clinically significant in transfusion and pregnancy settings. However, the majority of transfused individuals never form detectable alloantibodies. Expanding upon observations that children initially transfused with RBCs at a young age are less likely to form alloantibodies throughout their lives, we hypothesized that “non-responders” may not only be ignorant of antigens on RBCs but instead tolerized. We investigated this question in a reductionist murine model, in which transgenic donors express the human glycophorin A (hGPA antigen in an RBC-specific manner. Although wild-type mice treated with poly IC and transfused with hGPA RBCs generated robust anti-hGPA IgG alloantibodies that led to rapid clearance of incompatible RBCs, those transfused in the absence of an adjuvant failed to become alloimmunized. Animals depleted of CD4+ cells or treated with CD40L blockade prior to initial hGPA RBC exposure, in the presence of poly IC, failed to generate detectable anti-hGPA IgG alloantibodies. These non-responders to a primary transfusion remained unable to generate anti-hGPA IgG alloantibodies upon secondary hGPA exposure and did not prematurely clear transfused hGPA RBCs even after their CD4 cells had returned or their CD40L blockade had resolved. This observed tolerance was antigen (hGPA specific, as robust IgG responses to transfused RBCs expressing a third-party antigen occurred in all studied groups. Experiments completed in an RBC alloimmunization model that allowed evaluation of antigen-specific CD4+ T-cells (HOD (hen egg lysozyme, ovalbumin, and human duffyb demonstrated that CD40L blockade prevented the expansion of ovalbumin 323-339 specific T-cells after HOD RBC transfusion and also prevented germinal center formation.

    A case study involving a 55-year-old Caucasian male with end-stage glomerulosclerosis is presented here. Kidney biopsies showed no deposits on imunofluorescent microscopy. Relapsing massive haemoptysis and suspected bronchovascular malformation required lung lobectomy which revealed malformative and tortuous small blood vessels, with no vasculitis. Blood antinuclear antibodies, antineutrophil cytoplasmic antibodies and antiglomerular basement membrane antibodies were undetectable. Seric immunoglobulins and complement levels were normal. Three months later, arthralgia and joint oedema first appeared. Skin biopsy revealed vasculitis immune-reactive to immunoglobulin A. Systemic corticotherapy was then started. Two weeks later, the patient presented with abdominal pain melena and rectal bleeding (haematoquesia). Endoscopic study showed diffuse gastrointestinal haemorrhage. Angiographic study revealed diffuse lesions compatible with vasculitis and haemorrhage from multiple spots. Cyclophosphamide and then intravenous immunoglobulin were associated to treatment without response. Increasing blood loss occurred, with massive gastrointestinal haemorrhage and haemorrhagic ascitis. Death occurred due to uncontrolled diffuse bleeding. Necropsy findings showed generalised small vessels vasculitis compatible with Henoch–Schönlein purpura. PMID:22778211

    A 65-year-old man was admitted with history of claudication symptoms and painful skin lesions of the lower legs. Physical examination showed palpable purpura of the lower legs and livedo reticularis, most marked at the forefoot and toes. Computed tomography (CT) showed an aortic mass 2 cm above the bifurcation. This was treated after angiography with a covered stent. Biopsy of the skin lesions showed no sign of vasculitis and no cholesterol crystals. The patient was discharged and remained symptom-free for 9 months. He was readmitted at that time with recurrent complaints. CT revealed a subtotal stenosis of the aortic stent. A skin biopsy showed CD31-positive tumor cells in small arteries. Biopsy of a new osteolytic lesion in the ileum confirmed the diagnosis of angiosarcoma of the aorta. The patient decided in favor of palliative care and was discharged from the hospital. Primary tumors of the aorta, although they are rare, should be considered in the presence of an intravascular mass with stenosis to blood flow. A skin biopsy is easy to conduct and often leads to the final diagnosis. Georg Thieme Verlag KG Stuttgart. New York.

    Jr(a) is a high-frequency antigen found in all ethnic groups. However, the clinical significance of the anti-Jr(a) antibody has remained controversial. Most studies have reported mild hemolytic disease of the newborn and fetus (HDNF) in Jr(a)-positive patients. Recently, fatal cases of HDNF have also been reported. We report the first case of HDNF caused by anti-Jr(a) alloimmunization in twins in Korea. A 33-yr-old nulliparous woman with no history of transfusion or amniocentesis was admitted at the 32nd week of gestation because of vaginal bleeding caused by placenta previa. Anti-Jr(a) antibodies were detected in a routine laboratory examination. An emergency cesarean section was performed at the 34th week of gestation, and 2 premature infant twins were delivered. Laboratory examination showed positive direct antiglobulin test and Jr(a+) phenotype in the red blood cells and the presence of anti-Jr(a) antibodies in the serum in both neonates. The infants underwent phototherapy for neonatal jaundice; this was followed by conservative management. They showed no further complications and were discharged on the 19th postpartum day. Preparative management to ensure the availability of Jr(a-) blood, via autologous donation, and close fetal monitoring must be performed even in cases of first pregnancy in Jr(a-) women.

    Background Henoch-Schönlein purpura (HSP) is the most common vasculitis in children, characterized by triad of symptoms; palpable purpura without thrombocytopenia, abdominal pain, and arthritis. Renal involvement often occur in children with HSP. No data on the renal involvement of children with HSP in Indonesia, especially West Java. Objective To evaluate renal involvement in children with HSP. Methods Retrospective study was conducted in children with HSP in Department of Child Health, Hasan Sadikin Hospital, from 2006 to 2011. Characteristics and clinical manifestations was reviewed from medical record. HSP was diagnosed by American College of Rheumatology 1990 criteria or European League Against Rheumatism/Pediatric Rheumatology International Trials Organization/Pediatric Rheumatology European Society 2008. Results There were 128 patients, consisting of 82 male (64.9%) and 46 female (35.1%) with ratio 1.8:1. Mean age was 7.9 ± 2.9 years old which range from 6 month to 15 years. Peak morbidity was between 5-10 years old. Prevalence of HSP in Hasan Sadikin Hospital tend to raise from 2.7/100,000 in 2008 to 5.2/100,000 in 2010. In most patients (71%) purpura was the first symptom. Seventy-one patients (44.5%) had arthritis and 89 patients (69.5%) had abdominal pain, while renal involvement was in 28 patients (21.8%). Gastrointestinal manifestations tend to manifest in patients less than 5 years old (p = 0.267), while renal involvement tend to manifest in age group 11-15 years old (p = 0.015) with odds ratio 3.1 (95% confidence interval, 1.2-8.1). Conclusion Renal involvement in children with HSP is more common in age group 11 to 15 years old. PMID:24527410

    Levamisole has been increasingly used as an adulterant of cocaine in recent years, emerging as a public health challenge worldwide. Levamisole-associated toxicity manifests clinically as a systemic vasculitis, consisting of cutaneous, hematological, and renal lesions, among others. Purpura retiform, cutaneous necrosis, intravascular thrombosis, neutropenia, and less commonly crescentic nephritis have been described in association with anti-neutrophil cytoplasmic antibodies (ANCAs) and other autoantibodies. Here we report the case of a 49-year-old male who was a chronic cocaine user, and who presented spontaneous weight loss, arthralgia, and 3 weeks before admission purpuric skin lesions in the earlobes and in the anterior thighs. His laboratory tests on admission showed serum creatinine of 4.56 mg/dL, white blood count 3,800/μL, hemoglobin 7.3 g/dL, urinalysis with 51 white blood cells/μL and 960 red blood cells/μL, and urine protein-to-creatinine ratio 1.20. Serum ANCA testing was positive (>1:320), as well as serum anti-myeloperoxidase and anti-proteinase 3 antibodies. Urine toxicology screen was positive for cocaine and levamisole, with 62.8% of cocaine, 32.2% of levamisole, and 5% of an unidentified substance. Skin and renal biopsies were diagnostic for leukocytoclastic vasculitis and pauci-immune crescentic glomerulonephritis, respectively. The patient showed a good clinical response to cocaine abstinence, and use of corticosteroids and intravenous cyclophosphamide. Last serum creatinine was 1.97 mg/dL, white blood cell count 7,420/μL, and hemoglobin level 10.8 g/dL. In levamisole-induced systemic vasculitis, the early institution of cocaine abstinence, concomitant with the use of immunosuppressive drugs in severe cases, may prevent permanent end organ damage and associate with better clinical outcomes.

    Full Text Available Random donor platelet (RDP is not sufficient to improve the platelet count in most thrombocytopenic patients. Single donor platelet (SDP or buffy coat pooled platelet (BCPP are the two choices to provide a full therapeutic dose of platelets. However, there are constraints in the preparation of SDP due to stringent donor selection procedure, time required for procedure, and need of special expensive equipments and kits. BCPP is widely practiced, especially in the European countries, since 1995. In India, we decided to adopt the procedure of buffy coat pooling of platelets, especially for economically backward patients and for emergencies. This study was prospectively conducted from September 2009 to September 2010. A total of 129 units of BCPP [tested prior for viral markers by enzyme-linked immunosorbent assay (ELISA and individual donor nucleic acid amplification test (ID-NAT] were issued to 129 patients suffering from dengue and were included in this study. For comparison between efficacy of SDP and BCCP, patients were divided into two groups of 50 each. The post-transfusion platelet counts of the patients were noted after 2 hours of transfusion for each type of component. The platelet yield varied from 2.5 to 4.4 Χ 10ΉΉ in BCPP samples. The samples analyzed were sterile without any contamination. The different biochemical parameters were analyzed in detail. The observed post-transfusion platelet recovery and corrected count increment (CCI at 1 hour and 24 hours after BCPP transfusion were similar to that after SDP transfusion. Hence, we concluded that BCPP can be a low cost alternative to SDP in the times of emergencies like dengue and non-affordability by the patient for SDP.

    Full Text Available Purpura Henoch-Schonlein (PHS merupakan vaskulitis pada pembuluh darah kecil tersering terjadi pada anak. Penyakit ini ditandai dengan purpura palpablenontrombositopenia disertai salah satu gejala nyeri perut, artritis atau atralgia, glomerulonefritis, dan hasil biopsi jaringan berupa gambaran vaskulitis leukositoklastik. Bula hemoragik disertai edema jaringan subkutan merupakan gambaran yang tidak umum pada PHS dan sering terlewatkan. Manifestasi klinis vesikobulosa PHS sering ditemukan pada pasien dewasa, 16%–60% kasus, sedangkan pada anak kurang dari 2% kasus. Walaupun PHS secara tipikal merupakan penyakit selflimiting, tetapi komplikasi serius dapat terjadi. Perforasi gaster sangat jarang dilaporkan sebagai komplikasi PHS. Kami melaporkan 2 kasus PHS dengan manifestasi kulit yang berat, yaitu timbulnya bula hemoragik disertai dengan perforasi gaster. Pada kedua kasus dilakukan tindakan operatif dengan keluaran yang berbeda, pada kasus pertama pasien dipulangkan dalam kondisi baik pascaoperasi setelah dilakukan laparatomi eksplorasi, walaupun masih menderita nefritis. Sedangkan pasien kedua meninggal setelah tindakan diagnostic peritoneal lavagedisebabkan sepsis berat. Simpulan, bula hemoragik dapat dipertimbangkan sebagai prediktor komplikasi perforasi gaster pada PHS yang akan meningkatkan kewaspadaan dalam tata laksana PHS

    In addition to titration by indirect antiglobulin test most widely used, anti-D quantitation by continuous-flow analysis (CFA) may be performed to assess severity of maternal immunization. Only five studies have reported its added value in the management of pregnancies complicated by anti-D immunization. A retrospective study of 74 severe anti-D-immunized pregnancies was conducted from January 1, 2013, to December 31, 2014, in the Trousseau Hospital in Paris (France). Concentration of maternal anti-D was measured by titration and by CFA two-stages method (2SM; total amount of anti-D) and one-stage method (1SM; high-affinity IgG1 anti-D). These biologic data were analyzed according to the severity of the hemolytic disease of the fetus and the newborn. The value of 5 IU anti-D/mL in maternal serum is validated as a threshold to trigger ultrasonographic and Doppler fetal close follow-up. A high 1SM/2SM ratio was associated with a higher risk of intrauterine transfusion (IUT). For pregnancies requiring IUT and without increasing titer, maternal 1SM anti-D concentration tends to correlate with the precocity of fetal anemia. In the "without-IUT" group 1SM and 2SM anti-D concentrations correlate significantly with cord bilirubin levels of the newborn at birth. Altogether our results underline the importance of anti-D quantitation by CFA to optimize the management of anti-D-alloimmunized pregnancies. © 2017 AABB.

    Pregnancies at risk of fetal and neonatal alloimmune thrombocytopenia (FNAIT) are commonly treated using weekly intravenous immunoglobulin (IVIG) at 1 g/kg maternal weight. IVIG is an expensive multidonor human blood product with dose-related side effects. Our aim was to evaluate the effectiveness of IVIG at a lower dose, i.e., 0.5 g/kg. This was a randomized controlled multicenter trial conducted in Sweden, the Netherlands and Australia. Pregnant women with human platelet antigen alloantibodies and an affected previous child without intracranial hemorrhage (ICH) were enrolled. The participants were randomized to IVIG at 0.5 or 1 g/kg per week. The analyses were per intention to treat. The primary outcome was fetal or neonatal ICH. Secondary outcomes were platelet count at birth, maternal and neonatal IgG levels, neonatal treatment and bleeding other than ICH. A total of 23 women were randomized into two groups (low dose: n = 12; standard dose: n = 11). The trial was stopped early due to poor recruitment. No ICH occurred. The median newborn platelet count was 81 × 10(9)/l (range 8-269) in the 0.5 g/kg group versus 110 × 10(9)/l (range 11-279) in the 1 g/kg group (p = 0.644). The risk of adverse outcomes in FNAIT pregnancies treated with IVIG at 0.5 g/kg is very low, similar to that using 1 g/kg, although our uncompleted trial lacked the power to conclusively prove the noninferiority of using the low dose.

    Red cell transfusion is one of the main treatments in sickle cell disease. However there are potential risks of blood transfusions. In order to propose strategies to improve blood safety in sickle cell disease in Mali, we conducted a prospective study of 133 patients with sickle cell anemia recruited at the sickle cell disease research and control center of Bamako, November 2010 to October 2011. The study aimed to determine the prevalence of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) infections by serum screening and the frequency of red cell alloimmunization before and after blood transfusion. The diagnosis of sickle cell syndrome was made by HPLC, the detection of markers of viral infection was performed by ELISA, and the diagnosis of alloimmunization was conducted by the Indirect Coombs test. Prevalence of viral infections observed at the time of enrolment of patients in the study was 1%, 3% and 1% respectively for HIV, HBV and HCV. Three cases of seroconversion after blood transfusion were detected, including one for HIV, one for HBV and one another for HCV in sickle cell anemia patients. All these patients had received blood from occasional donors. The red cell alloimmunization was observed in 4.4% of patients. All antibodies belonged to Rh system only. Blood transfusion safety in sickle cell anemia patients in Mali should be improved by the introduction of at least the technique for detecting the viral genome in the panel of screening tests and a policy of transfusions of blood units only from regular blood donors.

    It is unusual for purpura to emerge as a result of drinking alcohol. Such a peculiarity was observed in a 55-year-old man with a 30-year history of heavy alcohol use. The Caucasian patient was studied for 11 years during several detoxification treatments. During the last 2 years of that period, purpuric rashes were newly observed. The asymptomatic purpura was limited to both lower limbs, self-limiting with abstinence, and reoccurring swiftly with alcohol relapse. This sequence was observed six times, suggesting a causative role of alcohol or its metabolites. A skin biopsy revealed histological features of purpura pigmentosa progressiva (termed Schamberg's disease). Additionally, alcoholic fatty liver disease markedly elevated serum immunoglobulins (immunoglobulin A and immunoglobulin E), activated T-lymphocytes, and increased C-reactive protein. In addition, moderate combined (cellular and humoral) immunodeficiency was found. Unlike the patient's immunoglobulin A level, his serum immunoglobulin E level fell in the first days of abstinence, which corresponded to the time of purpura decline. Systemic vasculitis and clotting disorders were excluded. The benign character of the purpura was supported by missing circulating immune complexes or complement activation. An alcohol provocation test with vinegar was followed by the development of fresh "cayenne pepper" spots characteristic of Schamberg's disease. This case report demonstrates that Schamberg's disease can be strongly related to alcohol intake, in our patient most likely as a late complication of severe alcoholism with alcoholic liver disease. Immunologic disturbances thereby acquired could have constituted a basis for a hypersensitivity-like reaction after ingestion of alcohol. Schamberg's disease induction by vinegar may point to an involvement of acetate, a metabolite of ethanol.

    Background and objective Henoch-Schönlein purpura (HSP) is an important cause of chronic kidney disease in children. This meta-analysis identified risk factors associated with renal involvement in childhood HSP. Methods PubMed, Embase, and Web of Science were searched. The quality of all eligible studies was assessed using the Newcastle-Ottawa scale criteria. An analysis of possible risk factors was conducted to report the odds ratio (OR) and weighted mean difference (WMD). Results Thirteen studies (2398 children) revealed 20 possible and 13 significant risk factors associated with renal involvement in HSP, with the following meta-analysis estimates of OR and WMD, with 95% confidence intervals: older age (0.90, 0.61–1.19); age > 10 y (3.13, 1.39–7.07); male gender (1.36, 1.07–1.74); abdominal pain (1.94,1.24–3.04); gastrointestinal bleeding (1.86, 1.30–2.65); severe bowel angina (3.38, 1.17–9.80); persistent purpura (4.02, 1.22–13.25); relapse (4.70, 2.42–9.14); WBC > 15 × 109/L (2.42, 1.39–4.22); platelets > 500 × 109/L (2.98, 1.22–7.25); elevated antistreptolysin O (ASO) (2.17, 1.29–3.64); and decreased complement component 3 (C3) (3.13, 1.62–6.05). Factors not significantly associated with renal involvement were: blood pressure; orchitis; elevated C-reactive protein; elevated erythrocyte sedimentation rate (ESR); and elevated serum IgA/IgE or IgG. Arthritis/arthralgia may be a risk factor according to the criteria of the American College of Rheumatology (1.41, 1.01–1.96). Conclusion The following are associated with renal involvement in pediatric HSP: male gender; > 10 y old; severe gastrointestinal symptoms (abdominal pain, gastrointestinal bleeding, and severe bowel angina); arthritis/arthralgia; persistent purpura or relapse; WBC > 15 × 109/L; platelets > 500 × 109/L; elevated ASO; and low C3. Relevant clinical interventions for these risk factors may exert positive effects on the prevention of kidney disease during the early

    Full Text Available Abstract Introduction Henoch-Schönlein purpura is the most common systemic vasculitis in children. Typical presentations are palpable purpura, abdominal pain, arthritis, and hematuria. This vasculitic syndrome can present as an uncommon cause of rectal bleeding in older patients. We report a case of an older man with Henoch-Schönlein purpura. He presented with rectal bleeding and acute kidney injury secondary to IgA mesangioproliferative glomerulonephritis. Case presentation A 75-year-old Polish man with a history of diverticulosis presented with a five-day history of rectal bleeding. He had first noticed colicky left lower abdominal pain two months previously. At that time he was treated with a 10-day course of ciprofloxacin and metronidazole for possible diverticulitis. He subsequently presented with rectal bleeding to our emergency department. Physical examination revealed generalized palpable purpuric rash and tenderness on his left lower abdomen. Laboratory testing showed a mildly elevated serum creatinine of 1.3. Computed tomography of his abdomen revealed a diffusely edematous and thickened sigmoid colon. Flexible sigmoidoscopy showed severe petechiae throughout the colon. Colonic biopsy showed small vessel acute inflammation. Skin biopsy resulted in a diagnosis of leukocytoclastic vasculitis. Due to worsening kidney function, microscopic hematuria and new onset proteinuria, he underwent a kidney biopsy which demonstrated IgA mesangioproliferative glomerulonephritis. A diagnosis of Henoch-Schönlein purpura was made. Intravenous methylprednisolone was initially started and transitioned to prednisone tapering orally to complete six months of therapy. There was marked improvement of abdominal pain. Skin lesions gradually faded and gastrointestinal bleeding stopped. Acute kidney injury also improved. Conclusion Henoch-Schönlein purpura, an uncommon vasculitic syndrome in older patients, can present with lower gastrointestinal bleeding

    Mammalian target of rapamycin (mTOR) inhibitors possess anticancer properties potentially useful in reducing posttransplantation malignancy. Besides controlling tumor-sensitive proliferative and angiogenic effects, mTOR influences transcription factors T-bet and Eomesodermin (Eomes) in CD8 cytotoxic T cells (Tc), which are key in rejecting tumors, and allografts. To study the role of mTOR in tumor and transplant immunity in an antigen-specific way, we used T-cell receptor transgenic B6.OTI recipients, B6.OVA.TG donors, and OVA-B16F10 melanoma cells. For tracking color-coded OTI-Tc cells associated with antitumor and alloimmunity in vivo, CD8-OTI transgenic reporter mice were created by crossbreeding DsRed-expressing B6.Nagy mice with B6.OTI mice. The role of mTOR in regulating the differentiation and function of alloreactive Tc cells in vitro was explored by stimulating OTI-Tc cells with ovalbumin-transgenic antigen-presenting cells in the presence of rapamycin or tacrolimus. Rapamycin, but not tacrolimus, induced a pro-antitumor phenotypic shift from CD62LCD44 effector memory Tc cells to CD62LCD44 central memory Tc cells, which featured up-regulated levels of T-bet and Eomes and preserved levels of interferon-γ and perforin. For future investigations, an in vivo model was established whereby DsRedOTI-Tc cells adoptively transferred into B6 mice bearing either a ovalbumin-transgenic mouse skin transplant or OVA-B16F10 tumor could be traced by fluorescence-activated cell sorting analysis as effector or memory Tc cells in transplant and tumor tissues. mTOR, but not calcineurin, inhibition spares antitumoral memory Tc cells by distinctively regulating T-bet and Eomes. This finding is now testable in a new tumor transplant model, which incorporates DsRedOTI-Tc cell tracing, opening the way to study the differential effects of immunosuppressants in posttransplantation malignancy.

    The aim of this study is to describe by video-nailfold capillaroscopy the microvascular involvement and capillary changes in children with Henoch-Schönlein purpura (HSp) and to establish a possible correlation with clinical outcome. Thirty-one patients underwent capillaroscopic evaluation through a videomicroscope during the acute phase and after 6 months. Twenty sex/age-matched controls were also examined. All capillaroscopic variables were statistically examined in combination with laboratoristic/clinical data. Architectural and morphological changes recorded during the acute phase were statistically significant in comparison to the controls (p capillaroscopy changes, laboratoristic/clinical data, and outcome. Video-nailfold capillaroscopy can be a simple tool to evaluate microvascular abnormalities in the acute phase of HSp, and the persistence of oedema could suggest an incomplete disease resolution at a microvascular level.

  13. A Case of Thrombotic Thrombocytopenia Purpura Associated with Systemic Lupus Erythematosus: Diagnostic Utility of ADAMTS-13 Activity

    Full Text Available Thrombotic thrombocytopenia purpura (TTP caused by a deficiency in ADAMTS-13 activity is considered to involve a subset of thrombotic microangiopathy (TMA. Although concept of TTP is included under the umbrella of TMA, discrimination of TTP from TMA is occasionally difficult in an autoimmune disorder. Herein, we report a case with TTP associated with systemic lupus erythematosus (SLE. In this case, it was difficult to discriminate TTP from TMA and the measurement of ADAMTS-13 activity was useful for obtaining an accurate diagnosis. SLE patients having thrombocytopenia in complication with anemia should be considered a monitoring of ADAMTS-13 activity even though the patients lacked symptoms of TTP related to the microvascular coagulation.

    Objective: To study the early diagnostic value of determination of urinary excretion amourt of proteins for renal damage in pediatric patients with AP. Methods: Morning arine specimen contents of albumin, IgG and β 2 -m (with RIA) as well as serum BUN and creatinine levels were measured in 25 pediatric patients with simple A P, 27 pediatric patients with purpura nephritis (PN) and 32 controls. Results: The urinary contents of proteins in all the patients were significantly higher than those in controls (P 0.05). Conclusion: Changes of urinary excretion of proteins occurred much earlier than changes of BUN and creatinine in purpura patients complicated with renal involvement and might be used as an indicator for early diagnosis.

    Objective: To investigate the relationship between changes of peripheral RBC immuno-function and serum TNF-α levels in pediatric patients with Henoch-Schoenlein purpura. Methods: RBC immuno-function status was studied with immunologic methods and serum TNF-α levels were measured with RIA in 31 pediatric patients with Henoch-Schoenlein purpura and 35 controls, Results: Levels of RBC-C3bRR were significantly lower and levels of serum TNF-α were significantly higher in the patients than those in controls (P<0.01). These two variables were significantly negatively correlated (r=-0.3018, P<0.05). On the contrary, the RBC-ICRRR levels were significantly higher in the patients (P<0.01) and were positively correlated with levels of TNF-α (r=0.3588, P<0.05). Conclusion: There were disturbances of RBC immuno-regulation with suppressed immuno-function in the purpura patients, which were related to the high levels of TNF-α. (authors)

  5. Cocaine-associated retiform purpura: a C5b-9-mediated microangiopathy syndrome associated with enhanced apoptosis and high levels of intercellular adhesion molecule-1 expression.

    Magro, Cynthia M; Wang, Xuan

    2013-10-01

    Cocaine-associated retiform purpura is a recently described entity characterized by striking hemorrhagic necrosis involving areas of skin associated with administration of cocaine. Levamisole, an adulterant in cocaine, has been suggested as the main culprit pathogenetically. Four cases of cocaine-associated retiform purpura were encountered in the dermatopathology practice of C. M. Magro. The light microscopic findings were correlated with immunohistochemical and immunofluorescence studies. All 4 cases showed a very striking thrombotic diathesis associated with intravascular macrophage accumulation. Necrotizing vasculitis was noted in 1 case. Striking intercellular adhesion molecule-1 (ICAM-1)/CD54 expression in vessel wall along with endothelial expression of caspase 3 and extensive vascular C5b-9 deposition was observed in all biopsies examined. Cocaine-induced retiform purpura is a C5b-9-mediated microvascular injury associated with enhanced apoptosis and prominent vascular expression of ICAM-1, all of which have been shown in prior in vitro and in vivo murine models to be a direct effect of cocaine metabolic products. Antineutrophilic cytoplasmic antibody and antiphospholipid antibodies are likely the direct sequelae of the proapoptotic microenvironment. The inflammatory vasculitic lesion could reflect the downstream end point reflective of enhanced ICAM-1 expression and the development of antineutrophilic cytoplasmic antibody. Levamisole likely works synergistically with cocaine in the propagation of this syndromic complex.

    Full Text Available > Background: Henoch-Schönlein purpura (HSP is a rare systemic small vessel vasculitis, which commonly occur in childrenbetween 2 and 10 years of age. The course of the disease is often self-limiting, although may manifest long-term renal morbidity. Theseverity of renal involvement decides about the prognosis of this disease. Many factors can trigger the disease attack, which is the mostcommon is bacterial invasion. Since the oral cavity is often refer as infectious foci to other part of the body, it seemed rationally tobe part that contribute the course of disease, thus management of these infectious foci, if possible, gives rise to an astoundingly goodprognosis. Purpose: This paper will describe a review on HSP and the possible association with oral and dental health since it mightbe related to the prognosis of HSP. reviews: Rashes in children are common; they may develop a rash after prescription of antibiotics.Nevertheless there are some childhood diseases that may manifest a rash presentation, such as HSP. It is important for pediatric dentistto have knowledge about HSP and consider the possibility of dental treatment or disease as potential triggers. Conclusion: Oral anddental condition may be the trigger cause of HSP attack. Therefore, it is important for pediatric dental practitioner to be aware of thecourse of the disease in order to limit the expanding complications.> latar belakang: Henoch-Schönlein purpura (HSP merupakan vaskulitis pembuluh darah kecil sistemik yang jarang terjadi danbiasanya menyerang anak usia 2 hingga 10 tahun.

    Autoimmune progesterone dermatitis (APD) is a rare autoimmune response to raised endogenous progesterone levels that occur during the luteal phase of the menstrual cycle. Cutaneous, mucosal lesions and other systemic manifestations develop cyclically during the luteal phase of the menstrual cycle when progesterone levels are elevated. APD symptoms usually start 3 - 10 days before menstruation and resolve 1 - 2 days after menstruation ceases. A 30-year-old woman presented with urticaria, petechiae and palpable pinpoint purpura lesions of the legs, forearms, neck and buttocks 1 week prior to her menses starting and 2 months after a medical abortion. She was diagnosed with allergic contact dermatitis and topical steroids were prescribed. Her skin conditions did not improve and were associated with her menstrual cycle. We performed an intradermal test using progesterone, which was positive. She was treated with oral contraceptive pills and the symptoms were resolved. This is a typical case of APD triggered by increased sensitivity to endogenous progesterone induced a few months after medical abortion.

    Full Text Available Introduction Recently, Henoch–Schönlein purpura (HSP has been observed in elderly people, although it was believed to be uncommon in these subjects. The increased risks of developing end-stage renal disease (ESRD in adults in comparison with children were highlighted by different studies; however, limited data are available on the treatment of HSP nephritis in adults. Methods Between 2002 and 2008, five elderly Japanese patients (>65 years old (mean age, 68 years, ranging from 65 to 72 with severe forms of HSP nephritis were entered into a prospective study to evaluate prednisolone therapy on the outcome of nephropathy in terms of clinical symptoms and histopathological changes. The patients were considered at risk of developing chronic renal failure when they presented with a nephrotic syndrome and crescentic glomeruli. Results At the last follow-up, 4–10 years after initiation of the therapy, four patients had clinically recovered and one died of lung cancer. No patients developed ESRD. The clinical outcome seemed to be correlated with glomerular activity (massive proteinuria and crescent formation. In spite of a relatively large dose of prednisolone, a few adverse effects, such as insomnia and skin lesions, were observed. Discussion Our preliminary small study suggests that renal outcome as well as survival of elderly patients with severe forms of HSP might be altered by aggressive prednisolone therapy.

    Toxic epidermal necrolysis (TEN) is a rare life-threatening condition almost exclusively attributed to drugs. The main etiologic factors for TEN are sulphonamides, anticonvulsants, and antibiotics; however, there are no published reports of warfarin causing TEN. We present the case of a 3-year-old patient who developed TEN while receiving treatment for Henoch-Schönlein purpura nephritis (HSPN). With multiple-drug therapy comprising prednisolone, mizoribine, dipyridamole, and warfarin, it is difficult to detect which drug is the causative agent. While in most cases, diagnosis of the causative drug is based on clinical history without a lymphocyte transformation test (LTT), we performed the test three times and identified the causative drug as warfarin at the late phase. We continued HSPN treatment without warfarin, and results showed good renal function without life-threatening complications. To our knowledge, this is the first report about TEN caused by warfarin. Repeated LTTs could be useful for identifying TEN-causative drugs even in the late phase.

    The immunoglobulin synthesizing activities of peripheral mononuclear cells (MNC) from five patients with Henoch-Schonlein purpura (HSP) and eight patients with active systemic lupus erythematosus (SLE) were compared. Cumulative amounts of IgM, IgG, and IgA synthesized and secreted by unstimulated and PWM-stimulated patient cells over a 12-day period were determied in a solid-phase radioimmunoassay. In unstimulated control cultures mean rates of IgM, IgG, and IgA synthesis were less than 250 ng/ml. The synthetic activities of patient MNC were markedly increased. In HSP cultures IgA was the major immunoglobulin class produced (2810 x/divide 1.33 ng/ml) followed by IgG (1754 x/divide 1.32 ng/ml) and IgM (404 x/divide 1.16 ng/ml). In SLE cultures IgA and IgG syntheses were equally elevated (4427 x/divide 1.20 and 4438 x/divide 1.49 ng/ml, respectively) whereas IgM synthesis averaged 967 x/divide 1.66 ng/ml. PWM stimulation of pateient MNC caused a sharp decline in the synthesis of all three immunoglobulin classes. After T cell depletion B cell-enriched fractions from HSP and SLE patients maintained high levels of IgA and IgG synthesis that were inhibited by PWM and by normal allogeneic but not autologous T cells. In PWM-stimulted co-cultures, patient T cells nonspecifically suppressed the synthetic activities of autologous and control B cells. in contrast patient B cells achieved normal levels of immunoglobulin synthesis when cultured with control T cells plus PWM. In longitudinal studies patient B and T cell disturbances persisted despite clinical improvement

Two vasculitis syndrome patients exhibited persistent symptoms and abnormal blood tests after treatment with conventional therapies.Methods: As the two cases had “blood stagnation” and “damps and heat” and one had a “yang deficiency” in terms of TCM theory, we applied certain selected Kampo medicines.Results: In case 1, the patient presented with hypereosinophilia, venous thrombosis, pulmonary infarction, decreased platelet count, ulner nerve palsy and Raynaud’s phenomena, which led to a diminished quality of life. After starting the Kampo medicines, the patient improved quickly and recovered within 11 months. In case 2, persistent purpura, abdominal pain, and bloody feces quickly improved and disappeared after Kampo treatment. After starting the Kampo medicines, prednisolone was stopped at 21 days without any sign of relapse to date.Conclusion: Kampo medicines helped clear the persistent abnormal symptoms and laboratory findings of vasculitis syndromes, Churg–Strauss syndrome and Henoch–Shönlein purpura, which had responded inadequately to the conventional therapies administered.Keywords: Kampo medicine, vasculitis, Churg–Strauss syndrome, Henoch–Shönlein purpura

    Henoch-Schönlein purpura nephritis (HSPN) involves the renal impairment of Henoch-Schönlein purpura and can easily relapse into life-threatening late nephropathy in severe cases. Although there is a lack of validated evidence for its effectiveness, Chinese herbal medicine (CHM) is one of the most commonly used methods in China to treat HSPN. It is thus need to report the protocol of a prospective cohort trial using CHM to investigate the effectiveness, safety and advantages for children with HSPN. This large, prospective, multicenter cohort study started in May 2015 in Shenyang. Six hundred children diagnosed with HSPN were recruited from 3 institutions and are followed-up every 2 to 4 weeks till May 2020. Detailed information of participants includes general information, history of treatment, physical examination, and symptoms of TCM is taken face-to-face at baseline. This study has received ethical approval from the ethics committee of institutional review board of the Affiliated Hospital of Liaoning University of Traditional Chinese Medicine (No.2016CS(KT)-002-01). Articles summarizing the primary results and ancillary analyses will be published in peer-reviewed journals. Clinical Trials Registration: NCT02878018.

The aim of this study is to elucidate the role of circulating complement proteins in the pathogenesis of childhood HSP.Plasma levels of C3a, C4a, C5a, and Bb in 30 HSP patients and 30 healthy controls were detected by enzyme-linked immunosorbent assay (ELISA. The expression of C3a receptor (C3aR, C5a receptor (CD88, E-selectin, intercellular adhesion molecule 1 (ICAM-1, C3, C5, interleukin (IL-8, monocyte chemotactic protein (MCP-1, and RANTES by human dermal microvascular endothelial cells (HMVEC-d was evaluated either by flow cytometry or by ELISA.At the acute stage, HSP patients had higher plasma levels of C3a (359.5 ± 115.3 vs. 183.3 ± 94.1 ng/ml, p < 0.0001, C5a (181.4 ± 86.1 vs. 33.7 ± 26.3 ng/ml, p < 0.0001, and Bb (3.7 ± 2.6 vs. 1.0 ± 0.6 μg/ml, p < 0.0001, but not C4a than healthy controls. Although HSP patient-derived acute phase plasma did not alter the presentation of C3aR and CD88 on HMVEC-d, it enhanced the production of endothelial C3 and C5. Moreover, C5a was shown in vitro to up-regulate the expression of IL-8, MCP-1, E-selectin, and ICAM-1 by HMVEC-d with a dose-dependent manner.In HSP, the activation of the complement system in part through the alternative pathway may have resulted in increased plasma levels of C3a and C5a, which, especially C5a, may play a role in the disease pathogenesis by activating endothelium of cutaneous small vessels.

    A 16-year-old boy presented with a number of asymptomatic pigmented macules on the volar aspect of his index fingers. Dermoscopy of each macule revealed a parallel ridge pattern of homogenous reddish-brown pigment. We propose that these lesions were induced by repetitive trauma from a Sony PlayStation 3 (Sony Corporation, Tokyo, Japan) vibration feedback controller. The lesions completely resolved following abstinence from gaming over a number of weeks. Although the parallel ridge pattern is typically the hallmark for early acral lentiginous melanoma, it may be observed in a limited number of benign entities, including subcorneal haematoma.

    Antiphospholipid syndrome is an autoimmune disorder characterized by the occurrence of venous and arterial thrombosis, as well as morbidity in pregnancy, in the presence of anti-phospholipid antibodies. The diagnosis of antiphospholipid syndrome is usually established based on clinical and laboratory findings by strictly following the 2006 Sapporo classification. However, the diagnosis remains challenging owing to the ongoing debates on the serological criteria. We report a case we describe as forme fruste antiphospholipid syndrome in which these criteria were not fulfilled. Purpura appeared repeatedly in a female infant starting from the age of 6 months and following episodes of upper respiratory infections and vaccinations. The levels of anti-cardiolipin IgG antibodies and anti-phosphatidylserine/prothrombin complex antibodies were elevated in accordance with these events. Histopathological evaluation revealed multiple small vessel thrombi in the dermis and adipose tissue. After 2 weeks of treatment with aspirin and heparin, the cutaneous symptoms subsided. Infection has long been associated with antiphospholipid syndrome, and anti-phosphatidylserine/prothrombin antibodies are considered a new marker for the diagnosis of antiphospholipid syndrome. Forme fruste antiphospholipid syndrome should be considered even if the antiphospholipid syndrome diagnostic criteria are not completely fulfilled, especially in the presence of elevated levels of anti-phosphatidylserine/prothrombin antibodies and known preceding infections.

    Background The development of gastrointestinal (GI) bleeding and end-stage renal disease (ESRD) can be a concern in the management of Henoch–Schönlein purpura (HSP). We aimed to evaluate whether the neutrophil-to-lymphocyte ratio (NLR) is associated with the prognosis of adult patients with HSP. Methods Clinical data including the NLR of adult patients with HSP were retrospectively analyzed. Patients were classified into three groups as follows: (a) simple recovery, (b) wax & wane without GI bleeding, and (c) development of GI bleeding. The optimal cut-off value was determined using a receiver operating characteristics curve and the Youden index. Results A total of 66 adult patients were enrolled. The NLR was higher in the GI bleeding group than in the simple recovery or wax & wane group (simple recovery vs. wax & wane vs. GI bleeding; median [IQR], 2.32 [1.61–3.11] vs. 3.18 [2.16–3.71] vs. 7.52 [4.91–10.23], P<0.001). For the purpose of predicting simple recovery, the optimal cut-off value of NLR was 3.18, and the sensitivity and specificity were 74.1% and 75.0%, respectively. For predicting development of GI bleeding, the optimal cut-off value was 3.90 and the sensitivity and specificity were 87.5% and 88.6%, respectively. Conclusions The NLR is useful for predicting development of GI bleeding as well as simple recovery without symptom relapse. Two different cut-off values of NLR, 3.18 for predicting an easy recovery without symptom relapse and 3.90 for predicting GI bleeding can be used in adult patients with HSP. PMID:27073884

    Full Text Available Henoch-Schönlein purpura (HSP is a small-vessel vasculitis of autoimmune hypersensitivity, and renin-angiotensin system (RAS regulates vascular homeostasis and inflammation with activation of cytokine release. Thus, we aimed to investigate the association between HSP and ACE I/D and AGT M235T polymorphisms. Genotyping was determined by allele specific PCR and PCR-RFLP. We obtained a significant difference in genotype distribution (p = 0.003 and allele frequencies (p 0.05 and allele frequencies (p > 0.05 of the AGT M235T polymorphism. Risk assessment showed significant risk for HSP in the subjects both with the ID + DD genotype (p = 0.019, OR: 2.288, 95% CI: 1.136–4.609 and D allele (OR: D vs. I: 2.0528, 95% CI: 1.3632–3.0912, p = 0.001 while no significant risk was obtained for HSP in the subjects both with the MT + TT genotype (p = 0.312, OR: 1.3905, 95% CI: 0.7326–2.6391 and T allele (OR: T vs. M: 1.065, 95% CI: 0.729–1.557, p = 0.743. Furthermore, when patients were stratified by the presence of certain systemic complications of HSP, no significant association was detected with ACE I/D, and AGT M235T polymorphisms. Our findings suggest that ACE I/D polymorphism is significantly associated with HSP susceptibility.

    Data from a small series suggested that the Interleukin 1 beta (IL1ß) rs16944 polymorphism may be associated with severe renal involvement and persistent renal damage (renal sequelae) in Henoch-Schönlein purpura (HSP). To confirm this association, we assessed the largest cohort of Caucasian HSP patients ever considered for genetic studies. 338 Spanish HSP patients and 635 sex and ethnically matched controls were recruited in this study. All patients were required to have had at least 6 months' follow-up. Patients and controls were genotyped for IL1β rs16944 by TaqMan genotyping assay. No differences between IL1β rs16944 genotype or allele frequencies were found either in the case/control study or when HSP patients were stratified according to the age at disease onset, presence of nephritis or gastrointestinal manifestations. Nevertheless, 4 (25%) of the 16 HSP patients who developed severe renal manifestations carried the TT genotype versus 29 (9%) of 322 who did not develop this complication (p=0.01, OR=5.48, 95% CI: 1.01-28.10). Accordingly, patients carrying the mutant T allele had an increased risk of developing severe nephropathy (p=0.016, OR=2.35, 95% CI: 1.09-5.07). Additionally, a significant increase of the TT genotype was observed in patients with persistent renal damage when compared with those patients without this complication (25% versus 8.6%, respectively; p=0.0035, OR=4.90, 95% CI: 1.26- 18.51). Moreover, renal sequelae were more common in patients carrying the mutant T allele (p=0.0076, OR=2.20, 95% CI: 1.17-4.14). Our results support that the IL1ß rs16944 polymorphism may be a potential marker of severe renal manifestations and renal sequelae in HSP.

    Henoch-Schönlein purpura (HSP) is the most common form of systemic small-vessel vasculitis in children, and HSP nephritis (HSPN) is a major complication of HSP and is the primary cause of morbidity and mortality. Previous studies have suggested that inducible nitric oxide synthase (iNOS) may play an important role in the pathogenesis of HSP. In this study, we performed a detailed analysis to investigate the potential association between iNOS polymorphisms and the risk of HSP and the tendency for children with HSP to develop HSPN in a Chinese Han population. A promoter pentanucleotide repeat (CCTTT)n and 10 functional single-nucleotide polymorphisms (SNPs) from 532 healthy controls and 513 children with HSP were genotyped using the MassARRAY system and GeneScan. The results suggested that the allelic and genotypic frequencies of the rs3729508 polymorphism were nominally associated with susceptibility to HSP. In addition, there was a significant difference in the allelic distribution of the (CCTTT)12 repeats and rs2297518 between the HSP children with and without nephritis; the HSP children with nephritis exhibited a significantly higher frequency of the (CCTTT)12 repeats and A allele of rs2297518 than the HSP children without nephritis (P FDR  = 0.033, OR = 1.624, 95% CI = 1.177-2.241 and P FDR  = 0.030, OR = 1.660, 95% CI = 1.187-2.321, respectively). Our results support that iNOS polymorphisms are associated with the risk of HSP and may strongly contribute to the genetic basis of individual differences in the progression to nephritis among children with HSP in the Chinese Han population. What is Known: • The etiology of HSP is unknown, but the genetic factors may play an important role in the pathogenesis of HSP. • iNOS could contribute to the development and clinical manifestations of HSP, and this has not been studied extensively so far. What is New: • Our results support that iNOS polymorphisms not only are associated with HSP risk but also

    Henoch-Schönlein purpura (HSP) is a multisystem, small vessel, leucocytoclastic vasculitis. It is predominantly a childhood vasculitis, rarely reported in adults. Studies have shown that several different genetic factors such as genes involved in inflammatory system and renin-angiotensin system (RAS) are important in the pathogenesis of Henoch-Schönlein purpura. The purpose of this study was to evaluate the independent effect of 3 gene polymorphisms including CCL2-2518 C/T, VEGF-634G/C and ACE(I/D) with HSP disease and their possible joint interactions in developing the disease. In this case-control study 47 HSP cases and 74 unrelated healthy controls were enrolled for evaluation. All individuals were genotyped for CCL2-2518C/T, VEGF-634G/C and ACE(I/D) gene polymorphisms. The possible association of these polymorphisms with susceptibility to develop HSP disease independently and in different joint combinations was evaluated. The frequencies of TT genotype and T allele of CCL2-2518C/T gene polymorphism and CC genotype and C allele of VEGF-634G/C gene polymorphism were significantly high in HSP children (p-values = 0.005 and = 0.007 respectively). Interestingly, studying the joint interaction of these 2 genotypes (CC genotype of VEGF G-634C and TT genotype of CCL2 C-2518T) in this cohort showed a more significant effect in the development of the disease (p gene when combined with II genotype of ACE gene in HSP children was significantly higher (p gene-gene interaction effects of CCL2, VEGF and ACE genes in developing HSP disease.

    We applied a radiolabeled Coombs antiglobulin test to the diagnosis and management of immune thrombocytopenia in adults and children. This assay substantiated that the majority of patients with idiopathic thrombocytopenic purpura have increased levels of IgG on their platelets. Platelets from a patient with the post-transfusion-purpura syndrome also carried increased IgG, indicating a role for IgG antibody or IgG-containing immune complexes in the destruction of host platelets in this disease. The radiolabeled Coombs test provides a general means to help diagnose, manage, and study immune platelet disorders

    BACKGROUND: Human platelet antigens (HPAs) are polymorphisms in platelet membrane glycoproteins (GPs) that can stimulate production of alloantibodies once exposed to foreign platelets (PLTs) with different HPAs. These antibodies can cause neonatal alloimmune thrombocytopenia, posttransfusion purpura, and PLT transfusion refractoriness. Most HPAs are localized on the main PLT receptors: 1) integrin αIIbβ3, known as the fibrinogen receptor; 2) the GPIb-IX-V complex that functions as the recepto...

    Full Text Available BACKGROUND: Henoch-Schönlein purpura (HSP is a systemic vasculitis involving small vessels with the deposition of immune complexes containing IgA. It has been extensively studied in children, but in adults, its natural history is much less known. OBJECTIVES: to report a series of patients with HSP presenting in their adulthood. PATIENTS AND METHODS: the Minas Gerais Vasculitis Study Group´s Members (MGVSG were invited to report patients with HSP who appeared in their adulthood. A standardized retrospective chart review was done. RESULTS: eleven patients, two male and nine female, age 39.4 +/- 20.1 yearsold were studied. Nine patients presented purpura, seven presented arthritis, four patients had gastrointestinal involvement and ten patients (91% presented glomerulonephritis (GN. Eight patients were subjected to renal biopsies. Six of them presented endocapillary proliferative GN and only two of them had minimal mesangial proliferation. In the other three patients, HSP was confirmed by skin biopsies. All patients received steroids, in five of them steroids were combined with other immunosuppressive agents. After a follow-up of 39.0 +/- 64.6 months, four patients (36% presented impairment of renal function, but only one (9% developed end stage renal disease and was successfully appeared to renal transplantation. At the end of follow-up, seven patients (64% are in complete remission and four in partial remission. CONCLUSION: in adulthood, HSP represents a distinct clinical syndrome with a higher frequency of renal involvement and more severe systemic vasculitis. Nevertheless, the final outcome in this series was as good as reported in children, maybe due to aggressive immunosuppressive therapy.INTRODUÇÃO: púrpura de Henoch-Schönlein (PHS é uma vasculite sistêmica que acomete vasos de pequeno calibre com depósitos de imunocomplexos contendo IgA.

    Full Text Available Patients of β-thalassemia major are dependent on regular blood transfusions for their entire lifetime. Development of antibodies against red blood cell (RBC antigen which may be alloantibody or autoantibody, several times as a result of frequent red cell component transfusions, further complicates the subsequent transfusion therapy. Among the autoantibodies, warm-reactive autoantibodies are commoner and interfere in the pretransfusion testing. These RBC autoantibodies present in patient's serum potentially react with all the cells of antibody identification panel giving “pan-reactive” picture and making alloantibody identification complex. In this report, we present our approach in a thalassemia patient who presented with warm-type autoimmune hemolytic anemia, low hemoglobin of 5.8 g/dl, and three significant alloantibodies (anti-D, anti-S, and anti-Jk b which were masked by pan-reactive warm autoantibody(s. Differential adsorption was used to unmask underlying alloantibodies. We suggest that differential adsorption procedure is an effective and efficient method for autoantibody adsorption, detection, and identification of masked alloantibody(s, especially in patients with low hemoglobin and history of recent blood transfusion.

    Hemolytic disease of the fetus and newborn (HDFN) occurs when fetal and neonatal erythroid cells are destroyed by maternal erythrocyte alloantibodies, it leads to anemia and hydrops in the fetus, and hyperbilirubinemia and kernicterus in the newborn. Postnatal care consists of intensive phototherapy and exchange transfusions to treat severe hyperbilirubinemia and top-up transfusions to treat early and late anemia. Other postnatal complications have been reported such as thrombocytopenia, iron overload and cholestasis requiring specific management. Areas covered: This review focusses on the current neonatal management and outcome of hemolytic disease and discusses postnatal treatment options as well as literature on long-term neurodevelopmental outcome. Expert commentary: Despite major advances in neonatal management, multiple issues have to be addressed to optimize postnatal management and completely eradicate kernicterus. Except for strict adherence to guidelines, improvement could be achieved by clarifying the epidemiology and pathophysiology of HDFN. Several pharmacotherapeutic agents should be further researched as alternative treatment options in hyperbilirubinemia, including immunoglobulins, albumin, phenobarbital, metalloporphyrins, zinc, clofibrate and prebiotics. Larger trials are warranted to evaluate EPO, folate and vitamin E in neonates. Long-term follow-up studies are needed in HDFN, especially on thrombocytopenia, iron overload and cholestasis.

    Case signifies the importance of knowledge of any preoperative drug intake and its anaesthetic implications. Also patients on dapsone therapy especially children should be monitored for methaemoglobin levels. Since children with immune thrombocy-topenic purpura are being treated with dapsone these days and many of these patients would be planned for splenectomy, monitoring of preoperative methaemoglobin levels and methaemoglobinemia as a cause of intraoperative pulse oximeter desaturation should be kept in mind.

Objective: The objective was to characterize demographically and clinically cases of erythrocyte alloimmunization at Transfusion Service of the University Hospital of the Valle (Cali, Valle del Cauca between 2011 and 2013. Methodology: A cross-sectional design of cases of red cell alloimmunization transfused between august 1th 2011 until july 31th 2013. The cases were included through a systematic random sampling. Epi-Info for Windows® was used for the development of the instrument, data entry and statistical analysis. The research was approved by the Ethics Committee on Research of the Universidad Autónoma de Bucaramanga and HUV. Results: Out of the eighty cases, 53.8 % were female and 46.2% were male. 65% were Hispanic and 35% African-American. 22.5% had a history of hematopoietic diseases and 45% were hospitalized for diagnoses included in this category of ICD-10. 79% of women had obstetric history. 18.75% were transfused previously. 36% of the cases had a CceeK- phenotype. 31.25% had alloantibody Anti-E followed by Anti-K 21.25%. Conclusions: The major alloantibody identified was Anti-E followed by Anti-K. Additionally, the associated alloantibody could not be identified in a large group mainly due to antibody mixture. Also, most cases correspond to young adults and adults. In the clinical characteristics of the sample a discrete representation of congenital hemoglobinopathies was observed and most were not previously polytransfused. [Pérez JA, Cortés A.

  19. How do we reduce plasma transfusion in Rhode Island?

    2017-08-01

    Plasma transfusions are given to patients with coagulopathy, either prophylactically, before an invasive procedure; or therapeutically, in the presence of active bleeding; and as an exchange fluid in therapeutic plasma exchange for disorders such as thrombotic thrombocytopenic purpura. There is consensus that many prophylactic plasma transfusions are non-efficacious, and the misdiagnosis of thrombotic thrombocytopenic purpura results in unnecessary therapeutic plasma exchange. Beginning in 2001, programs to reduce plasma transfusion in the three major teaching hospitals in Rhode Island were initiated. The programs evolved through the establishment of guidelines, education for key prescribers of plasma, screening of plasma prescriptions, and engagement of individual prescribing physicians for out-of-guidelines prescriptions with modification or cancellation. Establishment of an in-house ADAMTS13 (ADAM metallopeptidase with thrombospondin type 1, motif 13) assay in 2013 was used to prevent therapeutic plasma exchange in patients with non-thrombotic thrombocytopenic purpura microangiopathy. Transfusion service data were gathered at the hospital level regarding blood component use, hospital data for discharges, inpatient mortality, and mean case-mix index, and, at the state level, for units of plasma shipped from the community blood center to in-state hospitals. Between 2006 and 2016, a reduction in plasma use from 11,805 to 2677 units (a 77% decrease) was observed in the three hospitals and was mirrored in the state as a whole. This decline was not associated with any increase in red blood cell transfusion. Inpatient mortality either declined or was unchanged. An active program focused on education and interdiction can achieve a large decrease in plasma transfusions without evidence of patient harm. © 2017 AABB.

    Dengue infection has been associated with multiple renal complications, including glomerulonephritis, acute tubular necrosis, tubulointerstitial nephritis, and thrombotic microangiopathy (TMA), this last one being a rare complication of dengue, with only a few reported cases. TMA associated with dengue can be explained by an alteration in the activity of the enzyme ADAMTS13, leading to thrombotic thrombocytopenic purpura; or it can be secondary to direct or indirect endothelial injury by the virus, which leads to hemolytic uremic syndrome. Here, we present a case of severe TMA, not related to ADAMTS13, which was clearly associated with dengue infection. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Despite early recognition and intervention, the total serum bilirubin reached a maximum level of 39 mg/dL at 32 hours of life. Prior to an emergent exchange transfusion, the patient’s diagnostic evaluation was significant for Coombs-negative microangiopathic hemolytic anemia and thrombocytopenia. Further testing revealed a deficiency of ADAMTS13 protein, or von Willebrand factor-cleaving protease, a finding diagnostic of congenital thrombotic thrombocytopenic purpura, or Upshaw-Schulman syndrome.

The disturbing anamnestic data caused significant delay in correct diagnosis and in starting of fresh-frozen plasma therapy, so the woman and her fetus (in utero) had been died. The specific histological microangiopathic lesions could have been well documented by the autopsy of the mother, however no such alterations could have been detected in the fetus and placenta. This latter intriguing observation might be remarkable in the evaluation of several concepts dealing with the aetiopathogenesis of thrombotic microangiopathy. The short review of literature of thrombotic microangiopathy in pregnancy and puerperial period is also given.

    Many childhood diseases often present with skin abnormalities with which radiologists are largely unfamiliar. Knowledge of associated dermatologic manifestations may aid the radiologist in confirming the diagnosis and recommending targeted imaging of affected organs. We review the imaging findings in childhood diseases associated with dermatologic manifestations. Diseases include dermatologic findings which herald underlying malignancy (Neuroblastoma, leukemia/lymphoma, Langerhans cell histiocytosis),are associated with risk of malignancy (Epidermolysis Bullosa, basal cell nevus syndrome, Cowden's syndrome, Tuberous Sclerosis),or indicate a systemic inflammatory/immune disorder (Kawasaki's disease, Henoch Schonlein Purpura, systemic lupus erythematosus, scleroderma, sarcoidosis, dermatomyositis and immune thrombocytopenic purpura). Familiarity with pertinent findings in childhood diseases presenting with dermatologic manifestations in childhood diseases aids the radiologist in confirming the diagnosis and guiding imaging workup.

    Full Text Available Background: Thrombocytopenia is an important cause of bleeding. Different clinical conditions associated with thrombocytopenia and their reflections to the hemostatic table will be examined in this study. Methods: A total of 100 patients with thrombocytopenia who were treated in Hacettepe University between 1993 and 2013, 29 with thrombotic thrombocytopenic purpura (TTP, 36 with immune thrombocytopenic purpura (ITP, and 35 with aplastic anemia (AA, were included in the study. Clinical features and laboratory values were reviewed. Results: Thrombosis, fever, and sepsis were more frequently seen in TTP. The most common bleeding type was subcutaneous bleeding in all patient groups. Among patients with TTP, twenty-five patients (86, 2% had fever, 26 patients (89, 7% had a neurologic disorder, and 16 patients (55, 1% had renal dysfunction. Regarding the diagnostic criteria of TTP, 13 patients (44, 8% met five, 12 (41, 4% patients met four and 4 (13, 8% patients met three criteria. The median session of plasmapheresis was 17 (range; 2-127. There was no relation between session count and remission (p=0.28. Conclusion: The severity of clinical presentation and underlying disorders are the most important points with which to approach patients with thrombocytopenia. Clinical reflections may help to identify the cause of thrombocytopenia but not sufficiently demonstrative for diagnosis. [J Contemp Med 2017; 7(4.000: 316-322

    Thrombotic microangiopathies, namely thrombotic thrombocytopenic purpura and hemolytic uremic syndrome, are uncommon microvascular occlusive diseases. Despite the dramatic improvement in the outcome by exogenous plasma supply, either through plasma infusion or through plasma exchange, patients frequently require support in the intensive care unit. In the present study, we evaluated the outcome of a large cohort of patients with severe thrombotic microangiopathies. A retrospective multicenter study from January 1998 to June 2001. Fourteen French university hospital medical intensive care units. Sixty three adult patients with severe thrombotic microangiopathies. Of the 63 patients, 19 had a clinical presentation of thrombotic thrombocytopenic purpura, 18 had hemolytic uremic syndrome and 26 had combined neurologic and renal failures. Infections were the main etiology associated with thrombotic microangiopathies. The mortality rate was 35%. Of the survivors, all achieved complete remission. Whereas neurologic failure assessed through the Glasgow coma scale was an independent predictor of mortality [HR=0.845 (CI 95%: 0.759-0.940), P=0.002], renal impairment did not appear to be an adverse prognostic factor. The use of plasma exchange was independently associated with survival [HR=0.269 (CI 95%: 0.104-0.691), P=0.006]. Thrombotic microangiopathies with severe organ dysfunctions leading to hospitalization in the intensive care unit are associated with high mortality. Neurologic impairment appears to be the main adverse prognostic factor correlated to mortality, and the study confirms the importance of plasma exchange in the treatment of high-risk patients.

    Aims To characterize the pharmacokinetics (PK)/pharmacodynamics (PD) of eltrombopag in chronic liver disease (CLD). Methods The PK/PD model was developed using data from 79 CLD patients using nonlinear mixed-effects modelling. Results The PK of eltrombopag were described by a two-compartment model with dual sequential first-order absorption. Gender, race and severity of CLD were predictors of the apparent clearance of eltrombopag. The PD of eltrombopag in CLD were adequately described by a four-compartment lifespan model, in which eltrombopag stimulated platelet precursor production rate. East Asian CLD patients were less sensitive to the stimulatory effect of eltrombopag. Following a daily dose regimen of 50 mg eltrombopag, the time to achieve peak platelet counts was longer for the CLD population compared with patients who had immune thrombocytopenic purpura, but was comparable to patients with hepatitis C. Likewise, it took a longer time for platelet counts to rebound back to baseline once eltrombopag treatment was discontinued. Conclusions The time course of the platelet response in CLD was different from that in immune thrombocytopenic purpura but comparable to that in hepatitis C. PMID:24117976

    Upshaw-Schulman syndrome (USS) is a congenital thrombotic thrombocytopenic purpura (TTP) due to mutations in the gene that encodes for ADAMTS13 (ADAMTS13), but its clinical signs may be mild or absent during childhood. We have identified 37 patients with USS (24 females, 13 males) belonging to 32 families. The nine women from six families who were diagnosed during their first pregnancy are the focus of this report. Six of the nine women had episodes of thrombocytopenia during childhood misdiagnosed as idiopathic thrombocytopenic purpura. Thrombocytopenia occurred during the second-third trimesters in each of their 15 pregnancies, with 16 babies (one twin pregnancy), often followed by TTP. Of 15 pregnancies, eight babies were stillborn or died soon after birth, and the remaining seven were all premature except one, who was born naturally following plasma infusions to the mother that had started at 8 weeks' gestation. All nine USS women had severely deficient ADAMTS13 activity. ADAMTS13 analyses demonstrated that eight women were compound heterozygotes of Y304C/G525D (2 siblings), R125VfsX6/Q1302X (2 siblings), R193W/R349C (2 siblings), I178T/Q929X, and R193W/A606P; one woman was homozygous for R193W. Only the R193W mutation has been previously reported. These observations emphasize the importance of measuring ADAMTS13 activity in the evaluation of thrombocytopenia during childhood and pregnancy.

    Although deleterious mutations in interleukin-10 and its receptor molecules cause severe infantile-onset inflammatory bowel disease, there are no reports of mutations affecting this signaling pathway in Japanese patients. Here we report a novel exonic mutation in the IL10RA gene that caused unique splicing aberrations in a Japanese patient with infantile-onset of inflammatory bowel disease in association with immune thrombocytopenic purpura and a transient clinical syndrome mimicking juvenile myelomonocytic leukemia. A Japanese boy, who was the first child of non-consanguineous healthy parents, developed bloody diarrhea, perianal fistula, and folliculitis in early infancy and was diagnosed with inflammatory bowel disease. He also developed immune thrombocytopenic purpura and transient features mimicking juvenile myelomonocytic leukemia. The patient failed to respond to various treatments, including elemental diet, salazosulfapyridine, metronidazole, corticosteroid, infliximab, and adalimumab. We identified a novel mutation (c.537G > A, p.T179T) in exon 4 of the IL10RA gene causing unique splicing aberrations and resulting in lack of signaling through the interleukin-10 receptor. At 21 months of age, the patient underwent allogeneic hematopoietic stem cell transplantation and achieved clinical remission. We describe a novel exonic mutation in the IL10RA gene resulting in infantile-onset inflammatory bowel disease. This mutation might also be involved in his early-onset hematologic disorders. Physicians should be familiar with the clinical phenotype of IL-10 signaling defects in order to enable prompt diagnosis at an early age and referral for allogeneic hematopoietic stem cell transplantation.

    Full Text Available Anti-G has been reported as a possible cause of hemolytic disease of the fetus and newborn (HDFN, either independently or in association with anti-D, anti-C or both. The antibody mimics the pattern of anti-C and anti-D reactivity in the identification panel and is often present along with either or both of these antibodies. The differentiation of anti-D, -C and-G in routine pretransfusion workup is particularly essential in antenatal cases. We report two antenatal cases where anti-G was identified on advanced immunohematological workup, in addition to other alloantibodies.

    T cells from the spleens of C57BL 10 (H-2sup(b)) mice 7 to 12 days after immunization with P815Y (H-2sup(d)) mastocytoma cells have been shown to co-operate synergistically with an adherent component of non-immune starch induced peritoneal cells in the cytostasis of target cells. Although significant values for synergy could be obtained using the ( 125 I) UdR incorporation assay to measure cytostasis, normal peritoneal cells were incapable of co-operating with T cells in cytolysis as measured by 51 Cr release from pre-labelled target cells. Initially, the synergistic interaction was immunologically specific, but non-specific activity could be induced by challenge with specific antigen. (author)

    2015-09-01

    Full Text Available  AbstractBackground: Thrombotic microangiopathy (TMA is a rare syndrome that leads to excessive formation of blood clots, microthrombosis and is accompanied by non-autoimune haemolytic anemia and thrombocytopenia. Only few cases describing TMA caused by cancer are being reported in the literature.Patient: A 42-year old male patient with metastatic carcinoma of sigma and several accompanying diagnoses (pulmonary embolism, deep vein thrombosis, cerebrovascular insult had later developed clinical and laboratory signs of TMA. TMA was unresponsive to plasmapheresis, which was discontinued and first cycle of chemotherapy was applied. The patient died soon after. The autopsy did not provide any additional information about the disease, there were no signs of malignant bone marrow infiltration.Conclusion: The diagnosis of secondary TMA remains a diagnostic and therapeutic challenge. It appears as a rare complication in patients with cancer. Treatment is difficult because the cause of TMA (malignancy is hard to remove. Patients with cancer do not respond to plasmapheresis, which often delays the application of chemotherapy, the only effective treatment for TMA. Consequently this condition has poor prognosis.

    2012-01-01

    Partial splenic embolization (PSE) is a non-surgical procedure used to treat hypersplenism in various clinical settings and thus to avoid the disadvantages of splenectomy. PSE can be employed for the treatment of a variety of diseases including hypersplenism, thrombocytopenia, portal hypertension, splenic arterial aneurysms, etc. PSE can effectively relieve the splenic artery steal syndrome which occurred after liver transplantation, and therefore significantly improve the blood perfusion of the recipient liver. Besides, PSE can also be adopted to reduce the bleeding risk in patients with esophageal and gastric varices caused by portal hypertension. PSE is beneficial to the improvement of peripheral hematologic parameters, which helps the patients successfully undergo the high-dose chemotherapy or interferon therapy. In addition, PSE possesses potential curative effect for thrombocytopenia related diseases such as chronic idiopathic thrombocytopenic purpura. This paper aims to make a comprehensive review of the recent progress in the clinical application of partial splenic embolization. (authors)

    Rituximab is an anti-CD-20 chimeric monoclonal antibody that has shown substantial activity. Since its discovery, rituximab has been used with great success in a variety of hematological malignancies. Its success in the management of aggressive lymphomas led to expansion of its use in other conditions such as stem cell transplantation, post- transplant lymphoproliferative disorder, and other non-malignant conditions where B cell activation is thought to be important, such as idiopathic thrombocytopenic purpura and rheumatoid arthritis. The side effects have been remarkably few, particularly, infection is not more common that chemotherapy alone. This article reviews the structure, mechanism of action and uses of rituximab as monotherapy or in combination with chemotherapy. (author)

  6. Site of destruction of 111 indium-labeled autologous platelets and effectiveness of splenectomy

    1991-01-01

    Platelet life-span was studied in 165 patients (including 25 children) with chronic idiopathic thrombocytopenic purpura (of at least one year duration) using 111 indium-oxinate-labeled autologous platelets. The site of platelet destruction was not correlated with age, severity of the disease or presence of immunologic anomalies; this site was characteristic of each individual and remained unchanged in a given patient when the test was repeated several times. Splenectomy was performed in 79 patients (at the discretion of physicians who elected splenectomy in 63% of patients with splenic destruction versus 26% only of patients with hepatic destruction). A very close correlation was found between site of destruction and efficiency of splenectomy. However, 13% of initially improved patients developed a recurrence. Spontaneous improvement was seen in only 8 of the non-splenectomized patients with long-term follow-ups (1-5 years) [fr

    Ten children underwent splenic imaging with heat-denatured red blood cells labeled with technetium-99m (Tc-99m DRBC). The presenting problems included the heterotaxia syndrome, recurrent idiopathic thrombocytopenic purpura following splenectomy, mass in the left posterior hemithorax, and blunt abdominal trauma. In nine patients, the presence or absence of splenic tissue was established. A splenic hematoma was identified in the tenth patient. All patients were initially scanned with Tc-99m sulfur colloid (Tc-99m SC), and were selected for Tc-99m DRBC scintigraphy only after the results of the SC scans failed to establish the clinical problem beyond doubt. The availability of kits containing stannous ions, essential for efficient and stable labeling of red blood cells with Tc-99m and requiring only a small volume of blood, make splenic scintigraphy in children a relatively simple and definitive diagnostic procedure, when identification of splenic tissue is of clinical importance

    Full Text Available Objective: Most laparoscopic surgeons have attempted to reduce incisional morbidity and improve cosmetic outcomes by using less and smaller trocars. Single incision laparoscopic splenectomy is a new laparoscopic procedure. Herein we would like to present our experiences.Material and Methods: Between January 2009 and June 2009, data of the 7 patients who underwent single incision laparoscopic splenectomy were evaluated retrospectively.Results: There were 7 patients (5 females and 2 males with a mean age of 29.9 years. The most common splenectomy indication was idiopathic thrombocytopenic purpura. Single incision laparoscopic splenectomy was performed successfully in 6 patients. In one patient the operation was converted to an open procedure.Conclusion: With surgeons experienced in minimally invasive surgery, single incision laparoscopic splenectomy could be performed successfully. However, in order to demonstrate the differneces between standard laparoscopic splenectomy and SILS splenetomy, prospective randomized comparative studies are required.

  10. Helicobacter pylori infection and extragastric disorders in children: A critical update

    Pacifico, Lucia; Osborn, John F; Tromba, Valeria; Romaggioli, Sara; Bascetta, Stefano; Chiesa, Claudio

    2014-01-01

    Helicobacter pylori (H. pylori) is a highly prevalent, serious and chronic infection that has been associated causally with a diverse spectrum of extragastric disorders including iron deficiency anemia, chronic idiopathic thrombocytopenic purpura, growth retardation, and diabetes mellitus. The inverse relation of H. pylori prevalence and the increase in allergies, as reported from epidemiological studies, has stimulated research for elucidating potential underlying pathophysiological mechanisms. Although H. pylori is most frequently acquired during childhood in both developed and developing countries, clinicians are less familiar with the pediatric literature in the field. A better understanding of the H. pylori disease spectrum in childhood should lead to clearer recommendations about testing for and treating H. pylori infection in children who are more likely to develop clinical sequelae. A further clinical challenge is whether the progressive decrease of H. pylori in the last decades, abetted by modern clinical practices, may have other health consequences. PMID:24587617

    2012-05-01

    Full Text Available We present a case of a 57-year-old woman who underwent surgery for the removal of an ovarian mass but subsequently experienced microangioathic hemolytic anemia post-operatively, associated with fevers, renal insufficiency, hypertension, and hemolysis. While her clinical situations was initially suspicious for thrombotic thrombocytopenic purpura (TTP, further sorting of clinical information led to other explanations of these findings, including a systemic inflammatory response. Multiple triggers of the coagulation system which can lead to a common pathway of hemostatic failure were considered, and specific criteria seen in disseminated intravascular coagulation (DIC, TTP, heparin-induced thrombocytopenia (HIT, catastrophic antiphospholipid anitbody syndrom (APS, all of which can seem to overlap when a physician is faced with distinguishing the diagnosis clinically. We propose a chronologic and strategic approach for the clinician to consider when approaching this diagnostic dilemma.

    2016-02-01

    IVIG consumption is increasing due to the fact that in many cases the drugs are being used off-label. IVIG were more likely to be used in autoimmune and systemic inflammatory diseases. However, in randomized clinical trials, a good effect was achieved only in Kawasaki disease and immune thrombocytopenic purpura. Current clinical guidelines narrowed the indications for IVIG, limiting their use in sepsis. Immunoglobulin replacement therapy is recommended for children with physiological delay of immunoglobulin production only in repeated infections, which can not be controlled or prevented with antibiotics. In secondary ID, replacement therapy must be carried out if the cause of hypogammaglobulinemia can not be eliminated or elimination is contraindicated, as well as in association with β-cell cancers, in which severe infections caused by encapsulated bacteria persist despite preventive antibiotic therapy.

    Thrombotic microangiopathy (TMA) refers to phenotypically similar disorders, including hemolytic uremic syndromes (HUS) and thrombotic thrombocytopenic purpura (TTP). This review explores the role of the influenza virus as trigger of HUS or TTP. We conducted a literature survey in PubMed and Google Scholar using HUS, TTP, TMA, and influenza as keywords, and extracted and analyzed reported epidemiological and clinical data. We identified 25 cases of influenza-associated TMA. Five additional cases were linked to influenza vaccination and analyzed separately. Influenza A was found in 83%, 10 out of 25 during the 2009 A(H1N1) pandemic. Two patients had bona fide TTP with ADAMTS13 activity rational treatment approaches.

    Non-receptor type of protein-tyrosine kinase Syk (spleen tyrosine kinase) was isolated in the University of Fukui in 1991. Syk is known to be essential for the various physiological functions, especially in hematopoietic lineage cells. Moreover, ectopic expression of Syk by epigenetic changes is reported to cause retinoblastoma. Recently, novel Syk inhibitors were developed and its usefulness has been evaluated in the treatment of allergic rhinitis, rheumatoid arthritis, and idiopathic thrombocytopenic purpura. In this review, we will summarize the history, structure, and function of Syk, and then describe the novel Syk inhibitors and their current status. Furthermore, we will introduce our findings of the adaptor protein 3BP2 (c-Abl SH3 domain-binding protein-2), as a novel target of Syk.

  15. Idiopathic Thrombocytopenia with Iron Deficiency Anemia

    2013-01-01

    Full Text Available We report a rare case of anemia and thrombocytopenia as a result of uterine fibroid and adenomyosis, complicated by immune thrombocytopenic purpura (ITP. Symptoms were presented as menorrhagia and metrorrhagia in a 34-year-old African American woman, who was later treated with blood and platelet transfusion and iron therapy with steroids. Uterine fibroids are commonly found to cause hematologic disturbances such as anemia and reactive thrombocytosis and, less commonly, thrombocytopenia. Moreover, such hematologic disturbances are secondary to heavy and irregular uterine bleeding, which is typically presented. A previous uterine fibroid diagnosis was made and reconfirmed by pelvic and transvaginal ultrasound to exclude other locoregional pathologies. ITP was suggested by Coombs test and several other serologies, leading to confirmation via bone marrow biopsy. In a previous case study, we reported positive responses in hemotecrit and platelet count after the introduction of iron therapy to an iron-depleted middle-aged female presenting severe anemia and thrombocytopenia. 1

    Full Text Available The management of idiopathic thrombocytopenic purpura (ITP during pregnancy, especially with ongoing bleeding diathesis, has not been highlighted sufficiently in the literature. Aortocaval compression and reduction in uteroplacental circulation resulting in foetal hypoxia and acidosis, Mendelson′s syndrome due to gravid uterus, trauma to airway with resultant haemorrhage and aspiration into lungs, compromised airway due to short neck, anasarca and heavy breast, limitation in using invasive monitoring and regional anaesthesia and uncontrolled bleeding leading to placental hypoperfusion and foetal hypoxia are some of the important risks. In the present case report, anaesthetic management for splenectomy during pregnancy complicated with pregnancy induced hypertension and bleeding diathesis secondary to ITP is described with reference to above risks.

    Full Text Available Abstract The cornerstone in clinical evidence of the relative efficacy of thienopyridines (clopidogrel, ticlopidine versus aspirin in the secondary prevention of vascular disease is the Clopidogrel versus Aspirin in Patients at Risk of Ischaemic Events trial. This trial showed a modest benefit in the reduction of vascular events by clopidogrel. The results differed according to qualifying disorder: myocardial infarction, -3.7%; ischaemic stroke, +7.3%; and peripheral arterial disease, +23.8% (P = 0.042. Similar results were found for ticlopidine after brain ischaemia. The safety of clopidogrel appears to be similar to that of aspirin and better than that of ticlopidine. However, the recent report of thrombotic thrombocytopenic purpura in association with clopidogrel causes concern.

    Accessory spleens of 1.5 cm in size were preoperatively identified by the combined use of computerized tomography and splenic scintigraphy in two patients with hematologic diseases. After the accessory spleen had been removed from the first patient, who had persistent hereditary spherocytosis and had undergone a splenectomy 15 months before, a postoperative decrease in hyperbilirubinemia was noted. In the other patient who had idiopathic thrombocytopenic purpura, a successful accessory splenectomy was done at the same time as her splenectomy, and was followed by 6 months' complete remission. These events indicate that preoperative investigations using computerized tomography and scintigraphy are indispensable for ruling out an accessory spleen in those patients for whom splenectomy needs to be done in order to alleviate hematologic disorders.

    Full Text Available A 6-year-old girl underwent ureterocystoneostomy (UCN because of left flank pain due to delayed onset of ureteral stenosis one and a half years after endoscopic dextranomer/hyaluronic acid copolymer (Deflux injection for the treatment of vesicoureteral reflux (VUR. Histopathological examination indicated chronic inflammation with abundant eosinophils characteristic of a reaction to Deflux. Several autoimmune diseases developed during the treatment for ureteral stenosis. First, 2 weeks prior to the onset of left flank pain, she was diagnosed as having systemic lupus erythematosus. Finally, she died of pulmonary hemorrhage due to thrombotic thrombocytopenic purpura 4 months after UCN. The fatal outcome in this case was suspected to be caused by autoimmune syndrome induced by adjuvants, which in this case was the hyaluronic acid polymer injected into the ureteric orifice for the treatment of VUR.

    A patient with primary biliary cirrhosis and associated refractory immune thrombocytopenic purpura was treated with 4 weekly courses of rituximab, a monoclonal antibody targeting B-cell surface antigen CD20. Her thrombocyte count and even cholestatic liver function tests improved. However, 17 weeks after rituximab treatment, she developed severe neutropenia (absolute neutrophil count 0.23x10(3)/mul) and recurrent thrombocytopenia with abnormal bone marrow of all three lineages. Although delayed-onset neutropenia has been reported after rituximab, reactivated viral infections have also been encountered. Parvovirus B19 was suspected and confirmed as the cause of neutropenia in our patient. The patient was supported by GCSF treatment and recovered uneventfully after several weeks. Neutropenia after rituximab can also be the predominant manifestation of reactivated parvovirus B19 infection and have a favorable prognosis.
