purpura/diarrhea

This overview summarizes the history of thrombotic thrombocytopenic purpura (TTP) from its initial recognition in 1924 as a most often fatal disease to the discovery in 1997 of ADAMTS-13 deficiency as a major risk factor for acute disease manifestation. The cloning of the metalloprotease, ADAMTS-13,

BACKGROUND Thrombotic microangiopathy syndrome or thrombotic thrombocytopenic purpura-hemolytic uremic syndrome (TTP-HUS) describes distinct diseases sharing common pathological features: microangiopathic hemolytic anemia and thrombocytopenia, without any other apparent cause. METHODS An 18-year-old

BACKGROUND Congenital deficiency of ADAMTS13 is characterized by systemic platelet clumping, hemolytic anemia and multiorgan failure. Although, more than 100 mutations have been reported, atypical clinical presentation may be involved in diagnostic difficulties. METHODS A 2 year old Tunisian child

BACKGROUND Henoch-Schönlein purpura is a common immunoglobulin A-mediated vasculitic syndrome in children, characterized by purpuric rash, arthritis and abdominal pain. Renal involvement, manifested by the presence of hematuria and/or proteinuria, is also frequently seen. In most cases, patients

Henoch-Schönlein purpura (HSP) is a common vasculitis being characterized by the classic tetrad of nonthrombocytopenic palpable purpura, arthritis or arthralgias, gastrointestinal and renal involvement. Antigen-antibody (IgA) complexes activate the alternative complement pathway, resulting in

We report here on a 40-year-old woman with abdominal pain, low-grade fever, and diarrhea in whom the cutaneous features of Henoch-Schönlein purpura (HSP) appeared only a few days after acute abdominal symptoms. Endoscopy showed terminal ileitis, and histopathological examination of a biopsy of the

An infant with cytomegalovirus infection (CMV) developed idiopathic thrombocytopenic purpura (ITP) at 4 months of age. A bone marrow (BM) aspiration showed a remarkable increase of immature megakaryocytes and prominent proliferation of lymphoblasts. Flow cytometric analysis of the bone marrow cells

BACKGROUND 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

An older female underwent bariatric surgery which was followed by a significant weight loss and diarrhea, from which C. difficile was isolated just before her hospitalization. Less than 48 hours after admission, she became febrile, developed deep venous thrombosis of the leg and a pulmonary embolus.

Henoch-Schonlein purpura (HSP) is an immune-mediated vasculitis. HSP presents with purple spots on the skin (purpura), arthralgia, digestive problems, and kidney injury. HSP is most commonly seen in children, and rarely presents in adults. The pathogenesis involves the deposition of immune complexes

Sporadic cases and occasional outbreaks of hemorrhagic colitis recently have been associated with the rare Escherichia coli serotype O157:H7, which is now recognized as an important identifiable cause of bloody diarrhea in patients in whom more common gut pathogens cannot be detected. The authors
