Autoimmune hemolytic anemia (AIHA) is a rare and heterogeneous disease that affects 1 to 3/100 000 patients per year. AIHA caused by warm autoantibodies (w-AIHA), ie, antibodies that react with their antigens on the red blood cell optimally at 37°C, is the most common type, comprising ∼70% to 80% of all adult cases and ∼50% of pediatric cases. About half of the w-AIHA cases are called primary because no specific etiology can be found, whereas the rest are secondary to other recognizable underlying disorders...

Primary chronic cold agglutinin disease (CAD) is a well-defined clinicopathologic entity in which a specific, clonal lymphoproliferative B-cell bone marrow disorder results in autoimmune hemolytic anemia. The immune hemolysis is entirely complement-dependent, predominantly mediated by activation of the classical pathway and phagocytosis of erythrocytes opsonized with complement protein C3b. Typical clinical features in CAD have diagnostic and therapeutic implications. Pharmacologic treatment should be offered to patients with symptom-producing anemia or disabling circulatory symptoms...

The preferred treatment of idiopathic aplastic anemia (AA) is allogeneic hematopoietic stem cell transplantation (HSCT) from a human leukocyte antigen (HLA)-identical sibling donor. Transplantation from a well-matched unrelated donor (MUD) may be considered for patients without a sibling donor after failure of immunosuppressive therapy, as may alternative transplantation (mismatched, cord blood or haplo-identical HSCT) for patients without a MUD. HSCT may also be contemplated for congenital disorders in cases of pancytopenia or severe isolated cytopenia...

More than 80% of multiple sclerosis (MS) patients suffer from fatigue. Despite this, there are few therapeutic options and evidence-based pharmacological treatments are lacking. The associated societal burden is substantial (MS fatigue is a major reason for part-time employment or early retirement), and at least one out of four MS patients view fatigue as the most burdensome symptom of their disease. The mechanisms underlying MS-related fatigue are poorly understood, and objective criteria for distinguishing and evaluating levels of fatigue and tiredness have not yet been developed...

The autoimmune cytopenias are a related group of disorders in which differentiated hematopoietic cells are destroyed by the immune system. Single lineage disease is characterized by the production of autoantibodies against red cells (autoimmune hemolytic anemia [AIHA]), platelets (autoimmune thrombocytopenia [ITP]) and neutrophils (autoimmune neutropenia [AIN]) whereas multilineage disease may include various combinations of these conditions. Central to the genesis of this disease is the breakdown of central and/or peripheral tolerance, and the subsequent production of autoantibodies by both tissue and circulating self-reactive B lymphocytes with support from T helper lymphocytes...

The anemia of chronic kidney disease (CKD) is a common comorbidity seen in kidney diseases. It is also associated with increased cardiovascular morbidity and mortality and diminished quality of life. Often, patients with CKD of different stages require erythropoiesis-stimulating agents (ESAs) to maintain their hemoglobin (Hb) within the target range. Darbepoetin alfa is a newer ESA with a longer half-life than recombinant human erythropoietin (EPO). The objective of this study is to assess the efficacy and safety profile of twice-monthly (Q2W) and once a month (1QM) darbepoetin alfa in CKD patients, not on dialysis...

PURPOSE OF REVIEW: Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disorder characterized by progressive, poorly reversible airflow limitation. In addition to its pulmonary manifestations, COPD is also associated with several systemic expressions including anemia, osteoporosis, coronary artery disease, and malnutrition. In COPD, malnutrition is a consequence of reduced nutritional intake and muscle loss, further compounded by systemic inflammation. In the developing world, malnutrition is a significant problem by itself, even without any systemic illness...

Chronic anemia is common in liver cirrhosis. In this setting, the pathogenesis of anemia is complex and multifactorial. Spur cell anemia is a serious disorder in cirrhotic patients and is associated with poor prognosis. Liver transplantation constitutes the only therapeutic tool. We report a case with severe spur cell anemia in alcoholic liver cirrhosis. In the attempt to investigate the origin of the disorder, we have evaluated the lipoprotein profile and found a significant reduction of apolipoprotein AI and HDL3 subclass as a possible cause of the disease...

The classical definition of Chronic Obstructive Pulmonary Disease (COPD) as a lung condition characterized by irreversible airway obstruction is outdated. The systemic involvement in patients with COPD, as well as the interactions between COPD and its comorbidities, justify the description of chronic systemic inflammatory syndrome. The pathogenesis of COPD is closely linked with aging, as well as with cardiovascular, endocrine, musculoskeletal, renal, and gastrointestinal pathologies, decreasing the quality of life of patients with COPD and, furthermore, complicating the management of the disease...

Trypanosoma vivax has been associated with asymptomatic infections in African and South American buffalo. In this study, T. vivax was analyzed in water buffalo (Bubalus bubalis) from Venezuela in a molecular survey involving 293 blood samples collected from 2006 to 2015 across the Llanos region. Results demonstrated constant infections (average 23%) during the years analyzed. In general, animals were healthy carriers of T. vivax with low levels of parasitemia and were diagnosed exclusively by TviCATL-PCR. However, an outbreak of severe acute infections mostly in dairy animals was reported during a prolonged drought affecting 30...

BACKGROUND AND OBJECTIVES: Fanconi anemia (FA) is a rare genetic disorder caused by an impaired DNA repair mechanism which leads to an increased tendency toward malignancies and progressive bone marrow failure. The only curative management available for hematologic abnormalities in FA patients is hematopoietic stem cell transplantation (HSCT). This study aimed to report the results of HSCT in adult or adolescent FA patients. PATIENTS AND METHODS: Twenty FA patients with ages of 16 or more who underwent HSCT between 2002 and 2015 enrolled in this study...

Endothelial Nitric Oxide Synthase (eNOS) is crucial for vascular homeostasis. Polymorphisms T786C and G894T are reportedly affecting eNOS regulation and have been related to various diseases. Sickle Cell Disease (SCD), a clinically diverse chronic hemolytic anemia, implies impaired nitric oxide bioavailability. Aim of this study was to determine eNOS genotype for T786C and G894T polymorphisms in Greek patients with SCD and to elucidate its functional consequences and possible effects on clinical phenotype. Seventy nine steady state cases, most of them compound heterozygous for Sickle cell anemia/beta thalassemia and 48 controls were enrolled...

REVIEW
Amanpreet Singh, Yong-Jie Xu
Hydroxyurea is a well-established inhibitor of ribonucleotide reductase that has a long history of scientific interest and clinical use for the treatment of neoplastic and non-neoplastic diseases. It is currently the staple drug for the management of sickle cell anemia and chronic myeloproliferative disorders. Due to its reversible inhibitory effect on DNA replication in various organisms, hydroxyurea is also commonly used in laboratories for cell cycle synchronization or generating replication stress. However, incubation with high concentrations or prolonged treatment with low doses of hydroxyurea can result in cell death and the DNA damage generated at arrested replication forks is generally believed to be the direct cause...

Hidradenitis suppurativa, known as acne inversa, is a relapsing and chronic inflammatory skin disease affecting the skin folds. During the chronic course of the disease many local complications like fistulae to other tissues or systemic complications including anemia, secondary amyloidosis, lymphedema, nephrotic syndrome, artropathy may take place. Amyloid A amyloidosis is a rare complication of hidradenitis suppurativa, which has been described in a limited number of case reports. Herein, we present such a patient that had developed AA amyloidosis during the course of hidradenitis suppurativa...
