Thrombotic thrombocytopenic purpura (TTP) is a potentially lethal multisystem disorder which could be caused by autoimmune diseases. However, the concomitant occurrence of TTP and Sjögren's syndrome (SS) is an extremely uncommon scenario, especially in male patients. A 56-year-old Chinese male was admitted for the appearance of diffuse ecchymosis. Then he gradually developed transient slurred speech, progressive confusion, agitation, extremity weakness, and fever. Laboratory investigations suggested anemia, thrombocytopenia, significantly increased lactic dehydrogenase, schistocytes in peripheral blood smear, and a disintegrin-like metalloproteinase with thrombospondin motif type 1 member 13 (ADAMTS13) activity deficiency with high inhibitor titers...

BACKGROUND: Thrombotic thrombocytopenic purpura (TTP) is caused by the absence of ADAMTS13 activity. Thrombocytopenia is presumably related to the formation of microthrombi rich in von Willebrand Factor (VWF) and platelets. Obesity may be a risk factor for TTP; it is associated with abundance of macrophages that may phagocytose platelets. OBJECTIVES: To evaluate the role of obesity and ADAMTS13 deficiency in TTP, and to establish whether macrophages contribute to thrombocytopenia...

In systemic lupus erythematosus (SLE), the most commonly encountered finding related to platelets is thrombocytopenia whereas thrombocytosis is rarely reported. Our aim here was to reveal the type and the frequency of thrombocytosis in SLE patients along with its causes. Data of patients were evaluated retrospectively. Patients who had a platelet count of > 450,000/mm(3) (> 450 × 10(9)/L) in at least two subsequent counts and lasting more than 6 months during the follow-up were considered to have "persistent thrombocytosis"...

Introduction.Mycoplasma pneumoniae is a small cell-wall-lacking bacterium that belongs to the mycoplasma (Mollicutes) prokaryote micro-organisms. It is a common cause of both upper and lower respiratory tract infections in all age groups. Respiratory illness is the most common manifestation of M. pneumoniae infection; however, extrapulmonary involvement may be present or predominant. The skin, mucus membranes, central nervous system, cardiovascular system, haematopoietic system, kidneys and musculoskeletal system are the most commonly involved extrapulmonary sites...

Over the period 2010-2012, maternal mortality from infectious causes accounted for 5% of maternal deaths by direct causes and 16% of maternal deaths by indirect causes. Among the 22 deaths caused by infection occurred during this period, 6 deaths were attributed to direct causes from genital tract origin, confirming thus the decrease in direct maternal deaths by infection during the last ten years. On the contrary, indirect maternal deaths by infection, from extragenital origin, doubled during the same period, with 16 deaths in the last triennium, dominated by winter respiratory infections, particularly influenza: the 2009-2010 influenza A (H1N1) virus pandemic was the leading cause of indirect maternal mortality by infection during the studied period...

Protein C is an anticoagulant that is encoded by the PROC gene. Protein C deficiency (PCD) is inherited in an autosomal dominant or recessive pattern. Autosomal dominant PCD is caused by monoallelic mutations in PROC and often presents with venous thromboembolism. On the other hand, biallelic PROC mutations lead to autosomal recessive PCD which is a more severe disease that typically presents in neonates as purpura fulminans. In this report, we describe an 8-month-old infant with autosomal recessive PCD who presented with multiple lumps on his lower extremities at the age of 2 months and later developed purpura fulminans after obtaining a muscle biopsy from the thigh at the age of 5 months...

Emergency medicine practitioners treat bleeding patients on a regular basis. Disorders of hemostasis are an additional challenge in these patients but can be assessed and managed in a systematic fashion. Of particular importance to the emergency clinician are the iatrogenic causes of abnormal hemostasis. Other acquired causes of abnormal hemostasis include renal disease, immune thrombocytopenia, thrombotic thrombocytopenic purpura, hemolytic uremic syndrome, acquired coagulation factor inhibitors, acute traumatic coagulopathy, liver disease, and disseminated intravascular coagulopathy...

A 51 year old man presented with severe sepsis, disseminated intravascular coagulation (DIC) and multiorgan dysfunction after a 24 hour history of diarrhoea and malaise. Despite fluid resuscitation and receiving a platelet transfusion, freshfrozen plasma and intravenous broad-spectrum antibiotics, he remained anuric with a worsening metabolic acidosis. He was transferred to critical care for organ support including renal replacement therapy. He subsequently developed purpura fulminans. Blood cultures were positive for Captocytophaga carnimorsis, a gram-negative canine zoonosis that is an underdiagnosed cause of severe sepsis, for which DIC at presentation is characteristic...

Upshaw-Schulman syndrome (USS) is a thrombo-hemorrhagic disease caused by congenital deficiency of ADAMTS13 due to ADAMTS13 gene mutations. USS is characterized by repeated episodes of thrombocytopenia and microangiopathic hemolytic anemia that respond dramatically to infusions of fresh frozen plasma. There are two phenotypic expressions of USS: one is the early-onset type and the other, the late-onset type, is asymptomatic during childhood with the first bout of thrombotic thrombocytopenic purpura (TTP) developing after adolescence or during adulthood...

Immunoglobulin A vasculitis (IgAV), also referred to as Henoch-Schönlein purpura, is the most common form of childhood vasculitis. The pathogenesis of IgAV is still largely unknown. The disease is characterized by IgA1-immune deposits, complement factors and neutrophil infiltration, which is accompanied with vascular inflammation. Incidence of IgAV is twice as high during fall and winter, suggesting an environmental trigger associated to climate. Symptoms can resolve without intervention, but some patients develop glomerulonephritis with features similar to IgA nephropathy that include hematuria, proteinuria and IgA deposition in the glomerulus...

Introduction.Vibrio vulnificus (V. vulnificus) causes a severe infection that develops in the compromised host. Its pathophysiology is classified into three types: (1) primary septicaemia, (2) gastrointestinal illness pattern and (3) wound infection pattern. Of these, primary septicaemia is critical. V. vulnificus can be classified into three biotypes and two genotypes and its pathogenicity is type-dependent. Case presentation. A 47-year-old man presented to a local hospital with chief complaints of fever, bilateral lower limb pain and diarrhoea...

Autoimmune diseases, including multiple sclerosis and type 1 diabetes mellitus, affect about 5% of the worldwide population. In the last decade, reports have accumulated on various autoimmune disorders, such as idiopathic thrombocytopenia purpura, myopericarditis, primary ovarian failure, and systemic lupus erythematosus (SLE), following vaccination. In this review, we discuss the possible underlying mechanisms of autoimmune reactions following vaccinations and review cases of autoimmune diseases that have been correlated with vaccination...

Two patients with idiopathic oedema are presented describing their chronic tendency to accumulate fluid in the body and associated clinical features. One patient also tended to develop spontaneous purpura, which has been described in this condition. The other patient had an Odyssey in the healthcare system, before a final diagnosis of idiopathic oedema was reached and explained her different symptoms. Non-pharmacological interventions and various diuretics worked insufficiently, while ephedrine had an excellent efficacy in the second patient...

Essentials Plasmin is able to proteolyse von Willebrand factor. It was unclear if plasmin influences acute thrombotic thrombocytopenic purpura (TTP). Plasmin levels are increased during acute TTP though suppressed via plasmin(ogen) inhibitors. Allowing amplified endogenous plasmin activity in mice results in resolution of TTP signs. SUMMARY: Background Thrombotic thrombocytopenic purpura (TTP) is an acute life-threatening pathology, caused by occlusive von Willebrand factor (VWF)-rich microthrombi that accumulate in the absence of ADAMTS-13...

Thrombotic microangiopathy (TMA) describes a pathological process of microvascular thrombosis, consumptive thrombocytopenia, and microangiopathic hemolytic anemia, leading to end-organ ischemia and infarction, affecting particularly the kidney and brain. TMA is a pathological feature of a number of clinical disorders including thrombotic thrombocytopenic purpura, hemolytic uremic syndrome, and atypical hemolytic uremic syndrome. Rare but important, TMA may also occur in malignancy, connective tissue disease, malignant hypertension, and renal transplantation (rejection or drug toxicity)...

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...
