Clostridium perfringens (CP) gives several clinical settings, from an asymptomatic to a massive intravascular hemolysis. We report a case of fatal intravascular hemolysis due to CP septicemia having a hepatic supposed starting point in the emergency department. Like in many cases, the diagnosis was made when patient had already gone into shock and died. The CP septicemia often complicated the c...
Standard procedures have been described for measuring paramyxovirus-induced hemolysis. The choice of these procedures is based on the analysis of the behavior of eight different strains of Newcastle disease virus. Significant strain-specific differences in hemolytic activity have been found. The presence of at least two kinds of inhibitors of hemolysis in virus preparations necessitates the use...
Knowledge about the effects of cardiopulmonary bypass on malarial patients is scant. Malaria-induced hemolysis can exercerbate by performing extracorporeal circulation on a patient infected with Plasmodium and may, therefore, lead to a critical hemolysis jeopardizing the clinical outcome. A 52-year-old patient suffering from malaria and endocarditis was scheduled for urgent aortic valve replace...
A survey of caseous lymphadenitis was conducted at a goat and sheep slaughterhouse in Northeastern Brazil One hundred and fifty-eight goats and 43 sheep were examined for the presence of abscesses, with bacterial culturing of purulent material to define the etiological agent. Blood was collected simultaneously for determination of serological titer via the synergistic hemolysis-inhibition test ...
Multicenter trials in Southeast Asia have shown better survival rates among patients with severe malaria, particularly those with high parasitemia levels, treated with intravenous (IV) artesunate than among those treated with quinine. In Europe, quinine is still the primary treatment for severe malaria. We conducted a retrospective analysis for 25 travelers with severe malaria who returned from...
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare chronic hemolytic anemia characterized by an acquired defect of the erythrocyte which renders it susceptible to hemolysis by normal human serum. Previous reports have indicated that magnesium and factors resembling the components of complement are required for the hemolysis in vitro of PNH erythrocytes by normal serum (1, 2). Recently a natura...
The effect of Zn2+ on hemolysis induced by the thermostable direct hemolysin from Vibrio parahaemolyticus (vibriolysin) streptolysin O, and Triton X-100 was studied. We found that in certain buffers, such as tris(hydroxymethyl)-aminomethane-hydrochloride, boric acid-borax, and N-hydroxyethyl piperazine-N'-2-ethanesulfonic acid-sodium hydroxide, hemoglobins released from erythrocytes were easily...
OBJECTIVE Rapid infusion system allows rapid infusion of resuscitation fluids at body temperature in trauma patients. Packed red blood cells are subjected to high external pneumatic pressure (up to 300 mm Hg) and rapid infusion rates through a 170-microm filter. This study was conducted to outline hemolysis that may occur in the setting of massive transfusion (> 10 units). METHODS AND MATERIA...
Background Systemic inflammation alters energy metabolism. A sufficient glucose level, however, is most important for erythrocytes, since erythrocytes rely on glucose as sole source of energy. Damage to erythrocytes leads to hemolysis. Both disorders of glucose metabolism and hemolysis are associated with an increased risk of death. The objective of the study was to investigate the impact of in...
Hemolysis most commonly occurs following bone marrow transplant when there is "minor" ABO blood group incompatibility between donor and recipient. The hemolysis has been attributed to destruction of the patient's incompatible erythrocytes by donor-derived anti-A and/or anti-B antibody produced from "passenger" immunocompetent donor lymphocytes. Extraordinary transfusion requirements of group O ...
