Anemia is a common complication of chronic kidney disease (CKD) in children, and dysregulation of iron homeostasis plays a central role in its pathogenesis. Optimizing iron status is a prerequisite for effective treatment of anemia. Insufficient iron can lead to inappropriate escalation of the erythropoiesis-stimulating agent (ESA) dose, which is associated with adverse outcomes. Excess iron supplementation also has negative sequelae including free radical tissue damage and increased risk of systemic infection...

OBJECTIVE: The past studies found that the treatment of chronic myeloid leukemia (CML) with imatinib can induce the macrocytic anemia, moreover the incidence of anemia increases along with enhancement of imatinib concentration. This study was aimed to evaluate the potential relation of erythrocyte mean corpuscular volume (MCV) increase after the treatment with tyrosine kinase inhibitors (TKI) with the therapeutic response in patients with CML-chronic phase (CML-CP). METHODS: The clinical and hematologic data including MCV, molecular and cytogenetic response of 119 patients with CML-CP were collected after treatment with TKIs, and the relation of MCV changes after treatment with the clinical characteristics and therapeutic efficacy for patients with CML-CP was analyzed...

BACKGROUND: Cold agglutinin disease is a rare disorder characterized by an autoimmune hemolytic anemia occurring at low temperatures. Physical examination findings, often limited to acrocyanosis, are combined with a thermal amplitude test to help establish the diagnosis. Thermal amplitude testing determines the highest temperature at which the cold agglutination will occur and is an important parameter in diagnosing cold agglutinin disease. CASE PRESENTATION: Here we describe a 57-year-old white man of German and Nicaraguan descent with known chronic cold agglutinin disease who presented to our ophthalmology clinic for evaluation of a cataract...

HEV infection can lead to chronic hepatitis in immunosuppressed patients; extrahepatic manifestations are rarely seen. Here, we report a 13-year-old renal transplant patient with chronic hepatitis E and renal involvement. Ribavirin therapy led to temporary virus clearance and amelioration of kidney function. However, ribavirin therapy caused severe hyporegenerative anemia, which has so far only been reported in patients treated with a combination of ribavirin and interferon alpha.

BACKGROUND: Chronic transfusion therapy for sickle cell anemia reduces disease complications by diluting sickle-erythrocytes with hemoglobin A (HbA)-containing erythrocytes and suppressing erythropoiesis. Minor antigen mismatches may result in alloimmunization, but it is unknown if antigen mismatches or recipient characteristics influence HbA clearance posttransfusion. STUDY DESIGN AND METHODS: Children with sickle cell anemia on chronic transfusion therapy were followed prospectively for 12 months...

BACKGROUND: Autoimmune hemolytic anemia (AIHA) is caused by autoantibodies to red blood cells (RBCs), which can be panreactive and/or specific to Rh/other blood group antigens. We report a severe case of AIHA after bone marrow transplantation (BMT) due to autoanti-D triggered by reactivation of Epstein-Barr virus (EBV) infection. A combined strategy of D- RBC transfusion and administration of anti-CD20 monoclonal antibody (MoAb) resolved the hemolysis. CASE REPORT: A 33-year-old male underwent allogeneic BMT from an ABO-identical and HLA-matched unrelated male donor...

BACKGROUND: The incidence of anemia in kidney transplantation patients (KTPs) is very common and seems to be associated with the reduction in both renal function and physical exercise tolerance. The purpose of the present study was to compare biochemical markers of anemia and renal function of physically active and sedentary KTPs. METHOD: Serum hemoglobin (Hb), hematocrit (Hct), and serum creatinine (used to derive estimated glomerular filtration rate [eGFR]) were obtained from the medical records of 18 KTPs assisted at the Center for Prevention of Kidney Diseases of the Federal University of Maranhao Hospital...

Iron plays vital roles in the human body including enzymatic processes, oxygen-transport via hemoglobin and immune response. Iron metabolism is characterized by ~95% recycling and minor replenishment through diet. Anemia of chronic kidney disease (CKD) is characterized by a lack of synthesis of erythropoietin leading to reduced red blood cell (RBC) formation and aberrant iron recycling. Treatment of CKD anemia aims to normalize RBC count and serum hemoglobin. Clinically, the various fluxes of iron transport and accumulation are not measured so that changes during disease (e...

Iron overload is a concern for patients who require chronic transfusions as a result of inherited or acquired anemias, including sickle cell disease, thalassemia, and myelodysplastic syndromes. Iron chelation therapy (ICT) is the primary treatment for iron overload in these patients. The ICT deferasirox, which has been available as an oral dispersible tablet for liquid suspension, is now also available as a once-daily, film-coated tablet (FCT). Deferasirox FCT allows greater convenience and may be associated with fewer gastrointestinal side effects versus the original formulation...

Anemia is a common complication and contributes to increased morbidity and mortality in chronic kidney disease (CKD) patients. Whereas there has been a significant improvement of understanding the underlying mechanism of erythropoiesis, the treatment of renal anemia is still restricted to erythropoietin (EPO)-stimulating agents. The purpose of this article is to review the physiology of erythropoiesis, functional role of EPO and underlying molecular and cellular basis that regulate EPO production. Regulation of EPO production is at mRNA level...

Chronic lymphocytic leukemia (CLL) is the most prevalent leukemia with over 20,000 estimated cases in 2017. Leukemic involvement of the nervous system from CLL causing neurologic symptoms is reported in only about one percent of patients. Unfortunately, there is no current standard therapy for the treatment of CLL leptomeningeal disease. In this case, we discuss an unusual presentation of CLL leptomeningeal disease misdiagnosed as chronic rebound headache. A 61-year-old female was diagnosed with Rai stage I CLL in 2002...
