Recent studies suggest that platelet transfusions are harmful in patients with thrombotic thrombocytopenic purpura, an entity of thrombotic microangiopathies. As the typical or Shiga toxin-producing Escherichia coli-induced hemolytic uremic syndrome (STEC-HUS) is also classified as thrombotic microangiopathy, we complement these data with an analysis of 250 patients from the German O104:H4 STEC-HUS outbreak. The effect of platelet transfusion in 44 patients who received platelet transfusions vs 206 control patients was investigated...

Hemolytic uremic syndrome (HUS) is rare in neonates. We report the case of atypical HUS (aHUS) revealed by neonatal seizures. This 18-day-old baby presented with repeated clonus of the left arm and eye deviation. Four days earlier, she had suffered from gastroenteritis (non-bloody diarrhea and vomiting without fever). Her work-up revealed hemolytic anemia (120 g/L), thrombocytopenia (78 g/L), and impaired renal function (serum creatinine=102 μmol/L) compatible with the diagnosis of HUS. Levels of C3 and C4 in the serum were normal...

BACKGROUND: Acute kidney injury in patients with acute pancreatitis carries a poor prognosis. Hemolytic uremic syndrome (HUS) is characterized by non-immune hemolytic anemia, thrombocytopenia, and renal failure caused by platelet thrombi in the microcirculation of the kidney, and though rare in adults it is associated with high mortality and a high rate of chronic renal failure. CASE PRESENTATION: Herein, we report a case of alcohol-induced acute pancreatitis in a 38-year-old Chinese female complicated by HUS...

Pediatric hemolytic uremic syndrome (HUS) is a rare complication of infections usually caused by Escherichia coli; Streptococcus pneumoniae may be a causative agent in 5% of cases and is often more serious in terms of morbidity and mortality. We report a case of pediatric HUS following an infection by a serotype of S. pneumoniae not included in the vaccine administered to the child. Bacterial neuraminidase revealed a T-antigen and a Tk-antigen and red blood cells polyagglutinability in the laboratory test. Transfusion has been reoriented by an indication of secondary preparations: deplasmatisation of red blood cells and platelets and abstention of therapeutic plasma administration...

BACKGROUND: Platelet transfusions should be avoided in children with post-diarrheal hemolytic uremic syndrome (D + HUS) because they might increase microthrombi formation, thereby aggravating the disease. As this possibility has not yet been explored, we investigated whether platelet transfusion in patients with D + HUS would lead to a worse disease course compared to that in patients who did not receive platelet transfusion. METHODS: This was a case-control study in which data from D + HUS children who received platelet transfusions (cases, n  =  23) and those who did not (controls, n  =  54) were retrospectively reviewed and compared...

BACKGROUND: Thrombotic thrombocytopenic purpura is a hematological emergency and diagnostic challenge. The critical determinant of outcome is timely diagnosis and treatment. OBJECTIVES: Describe the pathophysiology, presentation, diagnosis, and treatment of thrombotic thrombocytopenic purpura. DISCUSSION: Thrombotic thrombocytopenic purpura has a varied presentation and a tendency to mimic several disorders. However, it may be at least provisionally diagnosed in the patient with thrombocytopenia and microangiopathic hemolytic anemia without alternate cause...

BACKGROUND: Acute kidney injury (AKI) with elevated serum uric acid (UA) levels has been reported in patients with hemolytic uremic syndrome (HUS). AKI is thought to result from tubular obstruction by UA crystals. Inducing a diuresis may ameliorate the oligoanuria in such patients. We describe a child with HUS in whom reducing UA with fluids and rasburicase appeared to accelerate the recovery of renal function. CASE-DIAGNOSIS/TREATMENT: A 9-month-old Caucasian male infant presented with 6 days of diarrhea, 3 days of vomiting, and 24 h of oliguria...

An outbreak of enterohemorrhagic Escherichia coli (EHEC) occurred in Toyama and other prefectures in Japan during 2011. Some patients, including adults, showed complications such as encephalopathy, disseminated intravascular coagulation, and hemolytic-uremic syndrome, and the disease course was extremely aggressive. This report describes the clinical features of four patients infected with Escherichia coli (E. coli) O111 who developed very severe to fatal complications. The initial symptoms in all patients included abdominal pain, diarrhea, and bloody stools, and neurological abnormalities started to appear from 1 to 3 days after admission...

In 1924, Dr Eli Moschcowitz described a 16-year-old adolescent girl with abrupt onset of petechiae, hemolytic anemia, followed by paralysis, coma, and death. Autopsy showed widespread hyaline thrombi in the terminal arterioles and capillaries of various organs. The syndrome described by Moschowitz is now known as thrombotic thrombocytopenic purpura.

Disseminated intravascular coagulopathy (DIC) is characterized as activation of the clotting system resulting in fibrin thrombi, gradually diminishing levels of clotting factors with increased risk of bleeding. Basically two types of DIC are distinguished: (1) chronic (compensated) - with alteration of laboratory values and (2) acute (non-compensated) - with severe clinical manifestations: bleeding, shock, acute renal failure (ARF), transient focal neurologic deficit, delirium or coma. Chronic DIC related to metastatic neoplasia is caused by pancreatic, gastric or prostatic carcinoma in most of the cases...

Thrombotic microangiopathies are disorders resulting from platelet thromboses forming in the microvasculature with resultant schistocyte forms. Hemolytic uremic syndrome (HUS) is a microangiopathic hemolytic anemia often complicated by acute renal failure in children. HUS is typically caused by bacterial infection, most commonly enterohemorrhagic Escherichia coli. Neuraminidase-producing organisms, such as Streptococcus pneumoniae have also been reported as potential etiologies. The pathogenesis in these cases involves cleavage of sialic acid residues from the surfaces of erythrocytes, platelets, and glomerular capillary endothelial cells, exposing the Thomsen-Friedenreich antigen, a process known as T-activation...

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...

Thrombotic thrombocytopenic purpura (TTP) is the common name for adults with microangiopathic hemolytic anemia, thrombocytopenia, with or without neurologic or renal abnormalities, and without another etiology; children without renal failure are also described as TTP. The diagnosis of TTP is an indication for plasma exchange treatment, but beginning treatment requires sufficient confidence in the diagnosis to justify the risk of plasma exchange complications. Documentation of a severe deficiency of plasma ADAMTS13 activity, defined as less than 10% of normal, is not essential for the diagnosis of TTP...

INTRODUCTION: Calcineurin inhibitor (CNI) induced HUS, although rare, can be a serious complication of renal transplantation. Classical syndrome of microangiopathic hemolytic anemia, thrombocytopenia, and acute renal injury may not be fully manifested. METHODS: We retrospectively analyzed our data in 950 kidney recipients under follow-up in our center (1994-2008). We reviewed the kidney biopsies performed for these patients to exclude conflicting diagnoses like antibody mediated rejection...

Children with hemolytic uremic syndrome (HUS) frequently develop acute kidney injury (AKI) requiring renal replacement therapy (RRT). Peritoneal dialysis (PD) is commonly used. Despite high rates of thrombocytopenia, there is concern that platelet transfusions may worsen HUS by exacerbating microthrombi formation. We evaluated bleeding risk for PD catheter placement with or without central venous catheter (CVC) placement in children with HUS. Records from 1998 to 2007 were searched. Data regarding patient demographics, PD catheter placement, CVC placement, occurrence of procedure-associated bleeding, and time from insertion to removal of PD catheter were collected...

Atypical hemolytic uremic syndrome (aHUS) is associated with complement system dysregulation, and more than 25% of pediatric aHUS cases are linked to mutations in complement factor H (CFH) or CFH autoantibodies. The observation of thrombocytopenia and platelet-rich thrombi in the glomerular microvasculature indicates that platelets are intimately involved in aHUS pathogenesis. It has been reported that a releasable pool of platelet CFH originates from alpha-granules. We observed that platelet CFH can arise from endogenous synthesis in megakaryocytes and that platelets constitutively lacking alpha-granules contain CFH...
