BACKGROUND Hemolyis of red blood cells is a serious toxic effect commonly found among patients envenomed by Hemiscorpius lepturus scorpion. OBJECTIVES The aim of the present study was to evlaute the efficay of the avaible polyvalent antivneom in preventing this phenomena. MATERIALS AND METHODS Using a red blood cell fragility test, the anti-hemolytic effectiveness of a new antivenom serum a...

Glucose-6-phosphate dehydrogenase deficiency is a common hemolytic genetic disorder, particularly in the areas endemic to malaria. The risk of drug induced Glucose-6-phosphate dehydrogenase deficiency related hemolysis depends on a number of factors including the Glucose-6-phosphate dehydrogenase variant. Aims: To know the G6PD deficiency and identify its variants in drug induced hemolysis in m...

Serum opacity factor (SOF) is a cell surface virulence factor made by the human pathogen Streptococcus pyogenes. We found that S. pyogenes strains with naturally occurring truncation mutations in the sof gene have markedly enhanced beta-hemolysis. Moreover, deletion of the sof gene in a SOF-positive parental strain resulted in significantly increased beta-hemolysis. Together, these observations...

Gadolinium (Gd), an element that possesses a character similar to that of calcium or magnesium, is known to have a strong hemolytic effect on erythrocytes (RBC) at even very low concentrations. 3, 5 One of the major characteristics of sickle cell disease is hemolysis of the abnormal RBC. Therefore, concerns have been raised that Gadolinium, as an MRI contrast agent for clinical use, should not ...

OBJECTIVES Hemolysis of blood samples drawn in the emergency department (ED) is a common problem that can interfere with timely diagnosis and appropriate treatment. The objective of this study was to identify the smallest number of remediable factors that independently increases the risk of hemolysis to design an effective strategy to address this issue. METHODS This was a prospective, observ...
