We describe a novel syndrome of severe toxic symptoms during intravascular hemolysis due to impaired hemoglobin scavenging in 2 children with acute myeloid leukemia undergoing CD33-directed therapy with the immunotoxin gemtuzumab ozogamicin (GO). A simultaneous high plasma hemoglobin, haptoglobin, and low bilirubin after septicemia-induced intravascular hemolysis indicated abrogated clearance o...

Victims of massive bee attacks become extremely ill, presenting symptoms ranging from dizziness and headache to acute renal failure and multiple organ failure that can lead to death. Previous attempts to develop specific antivenom to treat these victims have been unsuccessful. We herein report a F(ab)(´)(2)-based antivenom raised in horse as a potential new treatment for victims of multiple bee...

Red blood cells carry oxygen in the body and Glucose-6-Phosphate Dehydrogenase protects these cells from oxidative chemicals. If there is a lack of Glucose-6-Phosphate Dehydrogenase, red blood cells can go acute hemolysis. Convulsion is a rare presentation for acute hemolysis due to Glucose-6-Phosphate Dehydrogenase deficiency. Herein, we report a case report of a Glucose-6-Phosphate Dehydrogen...

Tumor lysis syndrome (TLS) is a life-threating hematologic emergency caused by massive lysis of tumor cells into the blood stream. TLS can be prevented and treated with rasburicase. Rasburicase-induced hemolysis and methemoglobinemia is a rare but serious complication. Screening for G6PD should be considered for patients at higher risk for G6PD deficiency who may be also at high risk for TLS on...

It is not known why people are more susceptible to bacterial infections such as nontyphoid Salmonella during and after a malaria infection, but in mice, malarial hemolysis impairs resistance to nontyphoid Salmonella by impairing the neutrophil oxidative burst. This acquired neutrophil dysfunction is a consequence of induction of the cytoprotective, heme-degrading enzyme heme oxygenase-1 (HO-1) ...

which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Autoimmune hemolytic anemia (AIHA) is an uncommon disorder characterized by hemolysis mediated by autoanti-bodies directed against self-red blood cells (RBC), with the incidence of 1–3 per 100,000/year and mortality rate of approximately 11% [1, 2]. AIHA is ...

platelet adherence surrounding leucocytes in a rosette formation or platelet satellitism is a rare phenomenon. this finding has been observed almost exclusively in ethylenediaminetetraacetic acid treated blood at room temperature. the mechanism underlying this phenomenon is not fully understood. in many reports of platelet satellitism platelets clump to polymorphonuclear neutrophils in healthy ...

 Wasp sting is a relatively common arthropod assault. This usually results in pain and mild allergic reactions, but sometimes may cause severe systemic reaction and multiorgan dysfunction including rhabdomyolysis, hemolysis, coagulopathy, hepatic, renal and cardiac complications. Along with several other pathomechanisms, rhabdomyolysis is a distinguished cause of acute kidney injury (AKI) in pa...

Arsenic hydrogen is a colorless gas. It enters the body through respiratory system, without irritating mucous membranes of upper tract. poison with primary hemolytic effect. In body, arsenic oxidized to and excreted from mainly kidneys intestines. The consequence rapid massive hemolysis anemia, hypoxia, damage parenchymal organs (kidneys, liver), nervous cardiovascular system. addition hemolysi...
