Abstract

To investigate the clinical features of Epstein-Barr virus-related hemophagocytic lymphohistiocytosis (EBV-HLH), to analysis the outcome of HLH-2004 protocol, and to explore the prognostic factors in EBV-HLH patients. The clinical features at onset and outcome of HLH-2004 protocol from 83 pediatric patients with EBV-HLH enrolled from January 2006 to December 2009 in our hospital were analyzed retrospectively. Univariate and multivariate COX regression analysis were used to identify statistically significant prognostic factors. (1) Among the 83 patients, 45 were males and 38 were females. The age of onset ranged from 6 months to 14 years 4 months. 44 patients were treated with HLH-2004, and 3-year overall survival (OS) was (55.8 ± 7.9)%. (2) The most common clinical features of EBV-HLH included high fever, cytopenia, hepatosplenomegaly, and coagulopathy; The respiratory symptoms, angina phlogistic, skin rashes, neurologic abnormality were rare. 97.3% of patients showed an elevation of serum ferritin, liver dysfunction and lipid metabolism disorders was found in most of EBV-HLH patients. 89.0% of patient had hemophagocytosis in bone marrow at diagnosis of EBV-HLH. (3) COX regression analysis revealed that anemia degree, serum alb...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
