BACKGROUND: Auto-immune thrombotic thrombocytopenic purpura (TTP) is a morbid multi-organ disorder. Cardiac involvement not recognized in initial disease descriptions is a major cause of morbidity. Therapeutic plasma exchange (TPE) requires exposure to multiple plasma donors with risk of transfusion-transmitted infection (TTI). Pathogen inactivation (PI) with amotosalen-UVA, the INTERCEPT Blood System for Plasma (IBSP) is licensed to reduce TTI risk. METHODS: An open-label, retrospective study evaluated the efficacy of quarantine plasma (QP) and IBSP in TTP and defined treatment emergent cardiac abnormalities...

Conversion disorder (CD) is sometimes accompanied by motor and sensory impairments, such as muscle weakness, paralysis, sensory hypersensitivity, and sensory loss. Sjögren's syndrome (SS) complicates 5-10% of cases of systemic lupus erythematosus (SLE). Patients with SS or SLE present with various neurological symptoms and psychiatric manifestations. When neurological symptoms are present, it is important to distinguish whether the symptoms are caused by a neurological or a mental disorder because the former requires early intensive intervention, such as methylprednisolone pulse therapy (MPT), whereas psychotherapy or antidepressant drugs are recommended for mental disorders...

Thrombotic thrombocytopenic purpura (TTP) is primarily caused by deficiency of ADAMTS13 within the blood stream due to either genetic defects or presence of inhibitory autoantibodies. Preclinical and clinical studies suggest that enzyme replacement therapy with recombinant human ADAMTS13 protein (rhADAMTS13) is effective and safe in treatment of TTP. However, frequent dosing would be required due to the relatively short half-life of rhADAMTS13 in circulation as well as the presence of inhibitory autoantibodies that collectively result in the poor pharmacological profile of rhADAMTS13...

IgA vasculitis is a small-vessel vasculitis mediated by immune complexes. In clinical terms, it is characterized by palpable purpura in the lower limbs, joint involvement in the form of arthralgia or arthritis, and gastrointestinal and renal involvement (this will mark a poorer prognosis in adults). Infectious processes, mainly in the upper respiratory tract, are frequently found to be triggers. On the other hand, human immunodeficiency virus (HIV) causes immune dysfunction, which triggers hypergammaglobulinemia and can trigger autoimmune disorders...

A 71-year-old man was referred to us with a right renal mass that was discovered by computed tomography (CT) examination for acquired hemophilia and leukemoid reaction. He presented with persistent low-grade fever and purpura on the lower legs caused by acquired hemophilia. Contrastenhanced CT scan showed a right renal tumor 6.0×7.4 cm in diameterwith inhomogeneous enhancement. The result of his urine cytology was negative. After improvement of his coagulation by treatment with immunosuppressants and steroids, he underwent open nephrectomy...

INTRODUCTION: Patients suffering from congenital thrombotic thrombocytopenic purpura (cTTP) have a deficiency in ADAMTS13 due to mutations in their ADAMTS13 gene. OBJECTIVE: The aim of this study was to determine ADAMTS13 parameters (activity, antigen and mutations), to investigate if the propositus suffered from child-onset cTTP and to study the in vitro effect of the ADAMTS13 mutations. METHODS: ADAMTS13 activity and antigen were determined using the FRETS VWF73 assay and ELISA and ADAMTS13 mutations via sequencing of the exons...

Malignant hypertension can cause thrombotic microangiopathy (TMA) characterized by hemolytic anemia and thrombocytopenia. On the other hand, severe hypertension is sometimes associated with hemolytic uremic syndrome (HUS) or thrombotic thrombocytopenic purpura (TTP). Distinguishing these entities is important because of therapeutic implications. Plasmapheresis should be initiated as soon as possible if we are dealing with TTP. We describe the case of a 30-year-old man referred to our hospital with malignant hypertension, severe renal failure and TMA: haemoglobin=9g/dL, total bilirubin=0...

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...

BACKGROUND: Thrombotic thrombocytopenic purpura (TTP) is caused by the abundance of uncleaved ultralarge von Willebrand factor multimers (ULvWF) due to acquired (autoantibody-mediated) or congenital vWF protease ADAMTS13 deficiency. Current treatment recommendations include plasma exchange therapy and immunosuppression for the acquired form and (fresh) frozen plasma for congenital TTP. CASE-DIAGNOSIS/TREATMENT: A previously healthy, 3-year-old boy presented with acute microangiopathic hemolytic anemia, thrombocytopenia, erythrocyturia and mild proteinuria, but normal renal function, and elevated circulating sC5b-9 levels indicating complement activation...

Pregnancy-related acute kidney injury (Pr-AKI) remains a large public health problem, with decreasing incidences in developing countries but seemingly increasing incidences in the United States and Canada. These epidemiologic changes are reflective of the advances in medical and obstetric care, as well as changes in underlying maternal risk factors. The risk factors associated with advanced maternal age, such as hypertension, diabetes, chronic kidney disease, and those associated with reproductive technologies such as multiple gestations, are increasing...

BACKGROUND: Rift Valley fever (RVF) is a zoonotic disease caused by Rift Valley fever virus (RVFV) found in Africa and the Middle East. Outbreaks can cause extensive morbidity and mortality in humans and livestock. Following the diagnosis of two acute human RVF cases in Kabale district, Uganda, we conducted a serosurvey to estimate RVFV seroprevalence in humans and livestock and to identify associated risk factors. METHODS: Humans and animals at abattoirs and villages in Kabale district were sampled...

Calciphylaxis is a rare vascular disorder characterized by calcification of arterioles which causes tissue inflammation and necrosis. It is associated with the metabolic disturbances seen in end stage renal disease (ESRD) and has also been described in patients with cirrhosis with preserved kidney function. Characteristic calciphylaxis lesions are black eschars surrounded by retiform purpura, and the gold standard for diagnosis is skin biopsy. Reported one-year mortality rates range between 45-80%. No treatment modality has been evaluated in a prospective randomized trial, and reports of treatment efficacy vary...

We herein report the case of a 61-year-old Japanese cirrhotic patient who developed rat bite fever (RBF) and whose first presentation was serious clinical features mimicking those of Henoch-Schönlein purpura (HSP). In addition to the critical clinical conditions, since the histopathology from purpuric skin eruptions was not inconsistent with that of HSP, therapy with prednisolone was promptly started in order to prevent his death. However, initial blood culture on admission yielded a small and slow-growing bacterial growth, which was gradually revealed by further subculture to be a peculiar bacterium, Streptobacillus moniliformis, leading to a definitive diagnosis of RBF...

Anti-neutrophil cytoplasmic antibody (ANCA) -associated vasculitis (AAV) and cryoglobulinemic vasculitis (CV) rarely coexist. An 83-year-old woman was admitted with rapidly progressive renal failure, gastrointestinal hemorrhage and purpura with myeloperoxidase (MPO) -ANCA positivity and cryoglobulinemia. Despite intensive immunosuppressive treatment, she died of aspergillus pneumonia. Autopsy revealed necrotizing crescentic glomerulitis in the majority of the glomeruli, accompanied by partially membranoproliferative-like glomerular changes...

A 44-year-old male patient was admitted to the hospital for observation after an unwitnessed syncope. Physical examination revealed skin purpura and bilateral tongue haematoma. Laboratory studies were unremarkable. Radiological imaging showed no abnormalities of the vasculature, signs of thrombosis or brain anomalies. Biopsy of a purpuric lesion revealed extravasation of erythrocytes. After excluding several causes of both syncope and purpura, the typical location of these thoracocervicofacial purpura, the tongue haematoma and an elevated prolactin level (which came back later) led to the diagnosis of an epileptic seizure...

Neonatal purpura fulminans (PF) is a life-threatening disorder caused by congenital or acquired deficiencies of protein C (PC) or S. PF presents as a cutaneous manifestation of disseminated intravascular coagulation. We describe a case of PF in a newborn with left leg ischemia and undetectable PC levels soon after birth. Despite anticoagulation therapy and PC concentrate, left foot amputation was required. Genetic testing of PROC for congenital PC deficiency was normal. This case highlights the course of PF due to acquired PC deficiency in a newborn treated with PC concentrate which is rarely described in the literature...

Eltrombopag is an oral thrombopoietin-receptor-agonist (TPO-RA) approved for the treatment of patients with chronic idiopathic thrombocytopenic purpura (ITP), who are more than one year old, and show poor response to first-line therapy. ITP is a hematological disorder characterized by isolated thrombocytopenia in the absence of secondary causes or disorders. Eltrombopag is generally well tolerated in the pediatric population, therefore therapeutic drug monitoring (TDM) is not usually performed in clinical practice...

Severe protein C (PC) deficiency leads to purpura fulminans and stroke in newborns. However, the clinical impact of plasma PC activity on the development of neonatal cerebral disease remains elusive. We report a case of hemorrhagic stroke associated with neonatal asphyxia and severe PC deficiency. Plasma PC and protein S activity 7 days after birth was 12% and 43%, respectively. No PROC mutation was found. PC levels did not exceed 20% until 2 months of age, even in the absence of consumption coagulopathy or vitamin K deficiency...

Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated fibro-inflammatory disorder characterized by specific pathological findings and elevated serum IgG4 level. IgG4-RD in the stomach is rare, and occasionally diagnosed as gastric subepithelial tumor (SET) by endoscopy or computed tomography scan. Two female patients in the age group of 40-50 years were diagnosed with 4 cm sized gastric SET. One underwent laparoscopic gastric wedge resection. Another one had a history of subtotal gastrectomy for early gastric cancer and idiopathic thrombocytopenic purpura with oral steroids administration...

Primary immune thrombocytopenia (idiopathic thrombocytopenic purpura; ITP) is an autoimmune disorder characterized by isolated thrombocytopenia without abnormalities in the erythroid and myeloid/lymphoid lineages. The incidence of ITP in adults is estimated at approximately 1.6-3.9 per 100 000 persons/year. The aim of this study was to analyze a case report of a patient with diagnosed immune thrombocytopenia (D69.3) resistant to cyclosporine A therapy as well as an evaluation of factors that could contribute to an inadequate response to cyclosporine A...
