Successful Treatment of Catastrophic Antiphospholipid Antibody Syndrome (CAPS) Associated With Splenic Marginal-zone Lymphoma With Low-molecular Weight Heparin, Rituximab and Bendamustine
ABSTRACT Case report A 69-year-old woman with splenic marginal-zone lymphoma was admitted with progressive abdominal pain and splenomegaly as the suspected cause of pain. Rituximab treatment (375 mg/m 2 ) had been initiated on the day of admission. Abdominal computerized tomography revealed splenic infarction. Laboratory tests showed elevation of liver enzymes and creatinine, low platelet count, prolonged partial thromboplastin time, and lupus anticoagulant positivity. The diagnosis of catastrophic antiphospholipid antibody syndrome was made. Weight-adjusted low-molecular weight heparin therapy was initiated. Freedom from symptoms and normalization of liver enzymes and creatinine occurred w…
Shunting of the Microcirculation After Mesenteric Ischemia and Reperfusion Is a Function of Ischemia Time and Increases Mortality
Shunting of the microcirculation contributes to the pathology of sepsis and septic shock. The authors address the hypothesis that shunting of the microcirculation occurs after superior mesenteric artery occlusion (SMAO) and reperfusion, and explore functional consequences.Spontaneously breathing animals (rats) (n = 30) underwent SMAO for 0 (controls), 30 (SMAO_30) or 60 min (SMAO_60) followed by reperfusion (4 h) with normal saline. Leukocyte-endothelial interactions in mesenteric venules were quantified in an exteriorized ileal loop using intravital microscopy. Abdominal blood flow was recorded continuously, and arterial blood gases were analyzed at intervals. The above groups were matched…
Small-Bowel Diagnosis in Patients with Familial Adenomatous Polyposis: Comparison of Push Enteroscopy, Capsule Endoscopy, Ileoscopy, and Enteroclysis
BACKGROUND: Conventional upper endoscopy (EGD), EGD with side-view endoscope and ileoscopy are established procedures for endoscopic evaluation of patients with familial adenomatous polyposis (FAP). However, we still have little data on the frequency and relevance of adenomas in those parts of the small bowel which are not accessible to EGD and ileoscopy. Adenomas distal to the duodenum are found more often in FAP patients with known duodenal adenomas. The question is, whether these patients can benefit from additional endoscopic and/or radiographic examinations. METHODS: Between July 2001 and August 2006 we performed comparative small bowel studies with push enteroscopy (PE), capsule endos…
C1-ESTERASE INHIBITOR REVERSES FUNCTIONAL CONSEQUENCES OF SUPERIOR MESENTERIC ARTERY ISCHEMIA/REPERFUSION BY LIMITING REPERFUSION INJURY AND RESTORING MICROCIRCULATORY PERFUSION
Activated complement contributes significantly to reperfusion injury after ischemia. This study explores functional consequences of C1-esterase inhibitor (C1-INH) treatment after superior mesenteric artery occlusion (SMAO)/ reperfusion using intravital microscopy. Thirty anesthetized, spontaneously breathing, male Sprague-Dawley rats underwent SMAO for 60 min followed by reperfusion (4 h). C1-esterase inhibitor (100 and 200 IU/kg body weight) or saline (0.9%) was given as a single bolus before reperfusion. Sham-operated animals (n = 10) without SMAO served as controls.Systemichemodynamicsweremonitoredcontinuously,arterial bloodgasesanalyzedintermittently, andleukocyte/ endothelial interacti…
