The oxidative hemolysis of rabbit erythrocytes induced by free radicals and its inhibition by chain-breaking antioxidants have been studied. The free radicals were generated from either a water-soluble or a lipid-soluble azo compound which, upon its thermal decomposition, gave carbon radicals that reacted with oxygen immediately to give peroxyl radicals. The radicals generated in the aqueous ph...

BACKGROUNDS Hemolysis related to a kinked prosthetic graft or inner felt strip is a very rare complication after aortic surgery. We describe herein a case of hemolytic anemia that developed due to aortic flap of the dissection and inversion of an inner felt strip that was applied at the proximal anastomosis of a replaced ascending aorta 10 years previously. CASE PRESENTATION A 74-year-old wom...

Diagnosis: Clostridium perfringens septic arthritis. Although the initial Gram stain of the sample of purulent material obtained from the patient’s shoulder (figure 1) revealed only rare gram-variable rods with no neutrophils, the culture eventually grew C. perfringens. The “double zone” of hemolysis seen in figure 2 is very characteristic of C. perfringens. The zone of partial hemolysis is due...

Shiga toxin is the main virulence factor of enterohemorrhagic Escherichia coli, a non-invasive pathogen that releases virulence factors in the intestine, causing hemorrhagic colitis and, in severe cases, hemolytic uremic syndrome (HUS). HUS manifests with acute renal failure, hemolytic anemia and thrombocytopenia. Shiga toxin induces endothelial cell damage leading to platelet deposition in thr...

THOUGH THE ORIGINS of erythrocyte glucose-6-phosphate dehydrogenase (G-6-PD) deficiency are rooted in human antiquity, the presence of drug-induced hemolysis in individuals subsequently felt to have G-6-PD deficiency was first reported in 1926 and the biochemical lesion responsible for this phenomenon elucidated in 1956 (1). In the United States, hemolysis induced by infection or drugs is the m...

Intravascular hemolysis is associated with several pathologic conditions that include hemoglobinopathies, trauma, malaria, and bacterial infections. Among plasma-protective proteins against oxidative damage caused by red blood cell rupture, haptoglobin and hemopexin are thought to play a crucial role. Haptoglobin and hemopexin, by binding with high-affinity hemoglobin and heme, respectively, ex...

Background. Various microRNAs (miRNAs) are used as markers of acute coronary syndrome, in which heparinization is considered mandatory therapy. Nevertheless, a standard method of handling plasma samples has not been proposed, and the effects of heparin treatment on miRNA detection are rarely discussed. Materials and Method. This study used quantitative polymerase chain reaction (qPCR) analysis ...

Passenger lymphocyte syndrome (PLS) is a well-recognized complication that may follow a hematopoietic progenitor cell or solid-organ transplant. Typically, the syndrome presents as acute hemolysis of the recipient's RBCs, which have become serologically incompatible with blood group antibodies formed by passively transfused donor-origin B lymphocytes. Most cases involve anti-A or anti-B. Howeve...

idiopathic acquired hemolytic atsemia, Group II, hemolytic atsemia followitsg irus pmseumomsia and Group III, chrotsic hemolytic atsemia with hemoglohitsuria and Raynaud’s phemsomena. A detailed accoumst. of the climsical aspects of tise three patients of Group III was published by Ferrimams, Dacie, Keele amid Fullerton2 who also made an amsalysis of msine similar cases reported in the literatu...

The association between primary biliary cirrhosis (PBC) and autoimmune hemolytic anemia (AIHA) is uncommon; only fourteen such case reports have been described. In this report, three patients who developed AIHA on the basis of PBC underwent successful therapy with corticosteroids and ursodeoxycholic acid (UDCA). Patient 3 was more complicated, suffering from PBC, Evans syndrome, Sjögren syndrom...
