Coombs-Negative Autoimmune Hemolytic Anemia in Crohn’s Disease
BACKGROUND Anemia is a common, important extraintestinal complication of Crohn's disease. The main types of anemia in patients with Crohn's disease are iron deficiency anemia and anemia of chronic disease. Although patients with Crohn's disease may experience various type of anemia, autoimmune hemolytic anemia (AIHA) in patients with Crohn's disease, especially Coombs-negative AIHA, is very rar...
متن کاملDirect antiglobulin ("Coombs") test-negative autoimmune hemolytic anemia: a review.
We have reviewed the literature to identify and characterize reports of warm-antibody type, autoimmune hemolytic anemia in which the standard direct antiglobulin reaction was negative but a confirmatory test indicated that the red cells were opsonized with antibody. Three principal reasons account for the absence of a positive direct antiglobulin test in these cases: a) IgG sensitization below ...
متن کاملAn Unusual Case of Hepatosplenic αβ T-Cell Lymphoma Presenting with Coombs'-Negative Hemolytic Anemia.
Hepatosplenic T-cell lymphoma (HSTCL) is a rare and aggressive extranodal T-cell lymphoma that comprises <5% of peripheral T-cell lymphomas. The majority of cases harbor the γδ T-cell receptor (TCR), but recently, a few cases have been shown to express the αβ TCR. Comparison of these two subtypes (αβ and γδ) shows similar clinicopathologic and cytogenetic features; however, due to the paucity o...
متن کاملHistiocytic Sarcoma Associated with Coombs Negative Acute Hemolytic Anemia: A Rare Presentation
Histiocytic sarcoma (HS) rarely involves extranodal sites, such as the spleen. We report a unique pediatric case of massive splenomegaly and refractory Coombs negative hemolytic anemia (CNHA) secondary to HS. The CNHA resolved completely after an emergent splenectomy. Next generation sequencing (NGS) revealed novel ASXL1, PTPN11, KIT, and TP53 mutations, unmasking a clonal heterogeneity within ...
متن کاملA Case of Non-Hodgkin's Lymphoma in Patient with Coombs' Negative Hemolytic Anemia and Idiopathic Thrombocytopenic Purpura
Coombs' negative autoimmune hemolytic anemia (AIHA) is a rare disease which shares similar clinical and hematological features with Coombs' positive AIHA, but its exact frequency remains unknown. There have been few reports of idiopathic thrombocytopenic purpura (ITP) and Coombs' negative AIHA associated with other lymphoproliferative disorders (LPDs). Since there is a well known association be...
