Helicobacter pylori (H. pylori) infects approximately half the world's population and is especially prevalent in the developing world. H. pylori is as an important cause of global ill health due to its known etiological role in peptic ulcer disease, dyspepsia, gastric cancer, lymphoma and, more recently recognised in iron deficiency anemia and idiopathic thrombocytopenic purpura. Increased antibiotic usage worldwide has led to antibiotic resistance among many bacteria, including H. pylori, resulting in falling success rates of first-line anti-H...

Despite widespread steroid usage for treating hematological conditions, minimal attention focuses on associated psychiatric side-effects. In the present study, we examined hematology patients' experiences of high-dose steroid treatment. This was undertaken by the use of a qualitative, descriptive design, which included convenience sampling and the inductive, cyclic, and constant comparative thematic analysis of interview transcripts. Eighteen patients participated, who were diagnosed with lymphoma, myeloma, leukemia, or idiopathic thrombocytopenia purpura...

BACKGROUND: Posterior reversible encephalopathy syndrome (PRES) is a condition characterized by seizures, altered consciousness, visual disturbances, and headache. Characteristic findings on neuroimaging include cerebral edema, typically involving the parieto-occipital white matter. PRES has been associated with hypertension, autoimmune disease, and Henoch-Schölein purpura (HSP), but few cases have been reported, and fewer cases of PRES have been reported in children. CASE REPORT: We report the case of a 4-year-old girl who presented with blindness and semi-consciousness...

Immune thrombocytopenia resulting from antibody-mediated platelet destruction combined with impaired platelet production is a common cause of thrombocytopenia. The decision to treat newly diagnosed patients is based on several factors including ceasing hemorrhagic manifestations, increasing the platelet count, prevention of bleeding, and inducing remission. Current standard first-line therapy is a course of corticosteroids. Although this treatment paradigm increases the platelet count in the majority of patients, a high percentage relapse after discontinuation of corticosteroid therapy...

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.

Unique challenges exist in the diagnosis and treatment of glomerular diseases with their onset during childhood. Mounting evidence supports the notion that earlier onset cases occur due to larger numbers of genetic risk alleles. Nearly all causes of adult-onset glomerulonephritis, nephrotic syndrome, and thrombotic microangiopathy have also been described in children, although the prevalence of specific causes differs. Postinfectious glomerulonephritis, Henoch-Schönlein purpura nephritis, and minimal change disease remain the most common causes of glomerular disease in younger children in the United States and can be diagnosed clinically without need for biopsy...

Thrombotic thrombocytopenic purpura (TTP) is caused by inactivation of a von Willebrand factor (VWF)-cleaving enzyme, ADAMTS13, which leads to platelet-rich thrombi comprising unusually large VWF multimers. We have found that ADAMTS13 can bind to the inactivated form of plasmin. In addition, plasmin cleaves purified ADAMTS13 into several fragments and inactivates it. Hence, we hypothesized that activation of plasminogen to plasmin becomes a new-onset factor for TTP due to ADAMTS13 inactivation. Plasmin was added exogenously or activated from plasminogen by streprokinase addition in HP...

Thrombocytopenia develops in 5% to 10% of women during pregnancy or in the immediate postpartum period. A low platelet count is often an incidental feature, but it might also provide a biomarker of a coexisting systemic or gestational disorder and a potential reason for a maternal intervention or treatment that might pose harm to the fetus. This chapter reflects our approach to these issues with an emphasis on advances made over the past 5 to 10 years in understanding and managing the more common causes of thrombocytopenia in pregnancy...

Thrombotic thrombocytopenic purpura (TTP) is a thrombotic microangiopathy caused by deficiency of von Willebrand factor-cleaving protease ADAMTS13. Large von Willebrand multimer formation and intravascular platelet aggregation affecting the arterioles and capillaries can result in death unless early treatment is administered. We report on the case of a child with TTP associated with a human herpes virus type-6 infection occurring during chemotherapy for acute lymphoblastic leukemia who was effectively treated by fresh frozen plasma infusions and antiviral therapy...

BACKGROUND: Leukocytoclastic vasculitis is typically mediated by deposition of immune complexes and is related to many causes, including medication. To the best of our knowledge, leukocytoclastic vasculitis related to cisplatin has not yet been described in the scientific literature. CASE PRESENTATION: We report a rare case of leukocytoclastic vasculitis after the first cycle of high-dose cisplatin chemotherapy in a patient with larynx carcinoma. A 48-year-old Caucasian man with larynx carcinoma received a high-dose of cisplatin monochemotherapy (100 mg/m2 every 21 days), along with 70 Gy of radiotherapy divided into 35 sessions, as a therapeutic schedule...

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/mm3 (> 450 × 109/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...
