p ATIENTS with acquired auto-immune hemolytic anemia associated with a decreased red cell production have been reported by several authors.1-5 We have observed such cases among patients with acquired auto-immune hemolytic anemia due to incomplete antibodies of the warm variety. There have been many reports6 ’ suggesting the sensitization and damages of erythroblasts in the bone marrow by anti-e...

Lymphoid follicles evolve in the perivascular connective tissue of many organs, including the thymuses, in NZB/Bl mice with hemolytic anemia. In previously published studies, these thymic follicles have been held to be causal in the autoimmune genesis of the hemolytic anemia. The present study contradicts this interpretation by demonstrating: (a) lymphoid follicles develop in the perivascular c...

Dapsone is a commonly used second line drug for prophylaxis of pneumocystis jirovecii pneumonia (PJP) in immunocompromised patients. Oxidant hemolysis, caused by dapsone's metabolite hydroxylamine, is a common side effect, and screening for glucose-6-phosphate dehydrogenase (G6PD) deficiency is recommended before the drug is started in order to prevent potential hemolytic reactions. We report a...

A UTOIMMUNE HEMOLYTIC ANEMIA may complicate a wide variety of diseases, among which are infectious diseases, “collagen” diseases, benign tumors, malignant tumors, lymphomas and Hodgkin’s disease.1’2 The lymphoproliferative disorders, especially chronic lymphatic leukemia, have often been associated with abnormal immunologic mechanisms. The myeloproliferative disorders are rarely associated with...

In this study, a 2.5-year-old boy suffering from a febrile seizure with normal laboratory tests and a history of immune hemolytic anemia was examined. Brain MRI demonstrated some tumors in the frontal, parietal, and occipital lobe that corroborated the pathology results of primary central nervous system lymphoma for the patient. The patient was treated with high- dose of Methotrexate. Our re...

Hyperuricemia developed in 2 children with autoimmune hemolytic anemia with reticulocytopenia at a time of hemolytic crisis. One likely cause of hyperuricemia is the destruction of nucleated RBC precursors by autoantibodies. It is advised that patients with autoimmune hemolytic anemia with reticulocytopenia be examined for hyperuricemia. This might explain the reason for reticulocytopenia and m...

BACKGROUND: Hemolytic anemia is a disorder characterized by the premature erythrocytes destruction. Phenylhydrazine (PHZ) induces oxidative stress and reactive oxygen species (ROS) formation, which causes hemolytic anemia. Cynara scolymus due to its antioxidant compounds, has been used for various therapeutic purposes in traditional medicine. OBJECTIVES: The present study was designed to evalua...

INTRODUCTION Mixed warm and cold autoimmune hemolytic anemia runs a chronic course with severe intermittent exacerbations. Therapeutic options for the treatment of hemolysis associated with autoimmune hemolytic anemia are limited. There have been only two reported cases of the effective use of rituximab in the treatment of patients with mixed autoimmune hemolytic anemia. We report a case of sev...

In the United States, most reported cases of babesiosis have been caused by Babesia microti and acquired in the northeast. Although three cases of babesiosis acquired in New Jersey were recently described by others, babesiosis has not been widely known to be endemic in New Jersey. We describe a case of babesiosis acquired in New Jersey in 1999 in an otherwise healthy 53-year-old woman who devel...

S 457 PNH, the development of aplastic anemia, and the finding of leukocyte and platelet abnormalities in this disease imply that this condition is not exclusively related to the red blood cells. Three cases from the Department of Hematology, University of S#{227}o Paulo Medical School are presented. After an initial phase, suggestive of aplastic anemia in cases 1 and 3, and of idiopathic acqui...
