Abstract:
Host blood protein digestion plays a pivotal role in the ontogeny and reproduction of hematophagous vectors. The gut of hematophagous arthropods stores and slowly digests host blood and represents the primary gateway for transmitted pathogens. The initial step in blood degradation is induced lysis of host red blood cells (hemolysis), which releases hemoglobin for subsequent processing by digestive proteolytic enzymes. The activity cycles and characteristics of hemolysis in vectors are poorly understood. Hence, we investigated hemolysis in two evolutionarily distant blood-feeding arthropods: Th

AbstractRare, congenital nonimmune hemolytic disorders of the erythrocyte, although uncommon, are important causes of anemia in the child and adult. These are a heterogeneous group of diseases that disrupt normal erythrocyte structure and function in varying ways. Predominant are abnormalities of hemoglobin stability, defects of erythrocyte metabolism, and disorders of erythrocyte hydration. Unstable hemoglobinopathies may lead to chronic or episodic hemolysis. Perturbation of critical enzymes of the Embden–Meyerhof pathway lead to altered erythrocyte metabolism and chronic hemolysis.

Abstract Medical advances in the management of patients with sickle cell disease, thalassemia, and other hemolytic anemias have led to significant increases in life expectancy. Improved public health, neonatal screening, parental and patient education, advances in red cell transfusion medicine, iron chelation therapy, penicillin prophylaxis for children, pneumococcal immunization, and hydroxyurea therapy have all likely contributed to this effect on longevity.1,2 Importantly, as a generation of patients with sickle cell disease and thalassemia ages, new chronic complications of these hemoglobi

<strong>Introduction:</strong>&nbsp;Favism is a genetic disease-causing hemolytic anemia in Mexico, primarily due to glucose-6-phosphate dehydrogenase (G6PD) deficiency. Factors triggering favism include infections, pregnancy, certain drugs, and eating beans. The disease is inherited recessively and is more common in men. Diagnosing and managing favism during pregnancy is crucial, as it can lead to severe hemolytic anemia and neonatal jaundice. &nbsp; <strong>Case presentation:</strong>&nbsp;A female patient, aged 18, presented with severe anemia and thrombocytopenia during her 20-week pregnan

Abstract:
Isolates of the Mycobacterium avium complex were examined for hemolysin expression. Only invasive isolates of M. avium were observed to be hemolytic (P &lt; 0.001), with activity the greatest for isolates of serovars 4 and 8. Thus, M. avium hemolysin appears to represent a virulence factor necessary for invasive disease.

Abstract:
Abstract The diagnosis of autoimmune hemolytic anemia (AIHA) can be made with a stepwise approach that aims to identify laboratory and clinical evidence of hemolysis and then determine the immune nature of hemolysis with the direct anti-globulin test. Once alternative causes for these findings have been excluded, AIHA is established, and the clinician must search for secondary causes, as well as identify the type of AIHA. Rituximab is now the preferred second-line treatment for primary warm AIHA and first-line treatment for primary cold agglutinin disease (CAD), either as monotherapy or combin

Hemolysis is observed in more than 50% of patients with cirrhosis. However, there has been little documention of the association of primary biliary cirrhosis with autoimmune hemolytic anemia. Two cases, found within a single practice, of primary biliary cirrhosis coexisting with autoimmune hemolysis and a third case coexisting with hereditary spherocytosis are presented. Anemia in such patients is commonly attributed to chronic disease, and hyperbilirubinemia is attributed to primary biliary cirrhosis.

Abstract Hemolytic anemia due to immune function is one of the major causes of acquired hemolytic anemia. In recent years, as more is known about the immune system, these entities have become better understood and their treatment improved.

In Section I, Dr. Peter Hillmen outlines the recent findings in the pathogenesis of paroxysmal nocturnal hemoglobinuria (PNH), relating the biochemical defect (the lack of glycosylphosphatidylinositol [GPI]-linked proteins on the cell surface) to the clinical manifestation

Abstract:
In sickle cell disease, nitric oxide (NO) depletion by cell-free plasma hemoglobin and/or oxygen radicals is associated with arginine deficiency, impaired NO bioavailability, and chronic oxidative stress. In transgenic-knockout sickle (BERK) mice that express exclusively human α- and βS-globins, reduced NO bioavailability is associated with induction of non-NO vasodilator enzyme, cyclooxygenase (COX)-2, and impaired NO-mediated vascular reactivity. We hypothesized that enhanced NO bioavailability in sickle mice will abate activity of non-NO vasodilators, improve vascular reactivity, decrease h

Historically, HDN was associated with a fetal death rate of about 1% in pregnancies. However, advancements in immunoprophylactic treatments have significantly improved management and outcomes when the condition is diagnosed early.

Cold agglutinins are antibodies that recognize antigens on erythrocytes at temperatures below normal body temperature. Antibodies are of IgM nature and bind to “I” or “i” antigens on red blood cells, causing agglutination in red blood cells. This situation results in anemia by creating extravascular hemolysis. If there is no underlying disease, it is called primary or idiopathic cold agglutinin disease (CAD), and if there is, it is called secondary cold agglutinin syndrome (CAS). Primary CAD is an extremely rare disease, with an incidence and prevalence of 1 per million and 16 per million, res
