hemolysis/fever

Heat treatment of human erythrocytes led to increased passive cation permeability, followed by haemolysis. K+ leakage was linear up to a loss of about 80% in the temperature range 46-54 degrees C. Kinetic analysis of the results revealed an activation energy of 246 kJ/mol, implicating a transition

Sheep erythrocytes sensibilized with the lipopolysaccharide (LPS) extracted from Coxiella burnetii phase 1 cells were used in indirect haemolysis test (IHT). The test was highly sensitive and specific. Its use seemed reasonable when following the chronic course of Q-fever by serologic methods.

Mediterranean spotted fever with haemolysis is reported in a glucose-6-phosphate dehydrogenase deficient Algerian man. The clinical course was unusually severe for a 27-year-old patient. The authors suspect G6PD deficiency to be a cause of enhanced severity in Mediterranean spotted fever as well as

Acute intravascular hemolysis (AIH) with hemoglobinuria is a rare complication of dengue viral infection. Review of the literature revealed only one report of AIH as a complication of dengue fever (DF). We report a case of AIH with massive hemoglobinuria in a 17-year-old Sri Lankan male, in the

We report a case of blackwater fever with brown plasma due to the presence of methemalbumin. The discovery of plasma with this color is a rare event at the laboratory. This compound appears during intravascular hemolysis or hemorrhagic pancreatitis when the ability of haptoglobin and hemopexin to

Renal damage in dengue haemorrhagic fever (DHF) has been reported in association with shock, haemolysis, rhabdomyolysis and sepsis. This report describes acute glomerulonephritis with DHF without the above-mentioned complications. A 3-year-old boy presented with fever, vomiting and oliguria. He had

Individuals with unstable hemoglobins may become more anemic during episodes of intercurrent viral or bacterial infections. Pathophysiologic mechanisms that are responsible for this phenomenon have not been elucidated. Recently we observed a patient with Hb Zürich [His E7(63)beta leads to Arg] whose

One hundred and four patients with Hodgkin's disease have been studied retrospectively in order to evaluate the relationship between fever associated with the disease (Pel-Ebstein type) and the development of anaemia. In the material 19 episodes of fever were found to be of this type. The mean loss

Hemolysis of human erythrocytes as a function of time of exposure to 47.4-54.5 degrees C was measured and correlated to thermal transitions in the membranes of intact erythrocytes as determined by differential scanning calorimetry (DSC). Curves of hemoglobin leakage (a measure of hemolysis) as a

Suspensions of yolk sac infected with rickettsiae of murine or of epidemic typhus, and indeed suspensions of liver or peritoneal washings from cotton rats infected with these organisms, when the suspensions contain a sufficient concentration of living rickettsiae, possess the capacity to hemolyze,

OBJECTIVE The research was conducted to understand more profoundly the pathogenetic aspects of the acute form of the African swine fever (ASF). METHODS A total of 10 pigs were inoculated with ASF virus (ASFV) (genotype II) in the study of the red blood cells (RBCs), blood and urine biochemistry in

Malaria is a serious and sometimes fatal disease caused by an intraerythrocytic parasite, and is commonly seen in developing countries. Approximately 1500 cases of malaria are diagnosed in the United States each year, mostly in travelers and immigrants returning from endemic areas [1]. There are
