Malarial infection induces tissue hypoxia in the host through destruction of red blood cells. Tissue hypoxia in malarial infection may increase the activity of HIF1α through an intracellular oxygen-sensing pathway. Activation of HIF1α may also induce vascular endothelial growth factor (VEGF) to
Using the sealed jar technique (also called residual oxygen bioassay), rainbow trout fry infected with Cryptobia salmositica were more susceptible than non-infected fish to environmental hypoxia. The Winkler technique (azide modification) was used to determine the residual dissolved oxygen in the
The effects of antimalarial treatment on the blood oxygen-transporting properties and on the tissue hypoxia were investigated in severe murine malaria, using mice infected with Plasmodium berghei (NK65). Five week old male ddY mice were inoculated intraperitoneally with 1 X 10(7) of P.
Babesiosis is an increasingly recognized disease which may benefit from therapeutic apheresis (Category II/Grade 2C). Vulnerable populations include the splenectomized, those aged >50, those with malignancies, and the immunocompromised. In the setting of parasite levels > 10%, significant anemia,
We report on a German couple found dead at home 7 days after returning from Burkina Faso. Postmortem evaluation revealed Plasmodium falciparum infection with a parasitemia of approximately 80% in both cases. No pathological findings of the organs were present at autopsy except moderate splenomegaly
The objectives of our study were to quantify the fetal cerebral artery and umbilical artery blood flow changes daily during a malaria crisis in a pregnant patient and evaluate the sensitivity and the specificity of Doppler indices for the prediction of acute fetal distress at the end of the
Malaria remains a challenging diagnosis with variable clinical presentation and a wide spectrum of disease severity. Using a structured case report form, we prospectively assessed 1,933 children at Mulago Hospital in Kampala, Uganda with acute Plasmodium falciparum malaria. Children with
Plasmodium yoelii infection in albino mice decreased the activity of brain glutamic acid decarboxylase (GAD) by about 30 and 48% in crude homogenate and its synaptosomal fraction, respectively. The decrease was evident from 20% parasitemia and remained more or less constant up to 80% parasitemia.
Adjunctive automated whole blood or red blood cell exchange (RBCEx) can rapidly decrease malarial hyperparasitemia. Several case reports and series suggest improvement in clinical symptomatology; however, recent Centers of Disease Control and Prevention (CDC) recommendations concluded that RBCEx has
BACKGROUND
Theileria annulata is a blood parasite affecting ruminants. Hemolytic anemia, secondary hypoxia, and vasculitis are the most important features of tropical theileriosis.
OBJECTIVE
Evaluation of electrocardiographic findings and changes in cardiovascular biochemical markers including cTnI
Non hemodynamic pulmonary edemas included by some authors in the acute respiratory distress syndrome (ARDS) had been reported in cerebral malaria. We describe a new case. Clinical data, hemodynamic studies with PWP measurement, and anatomic findings are coherent with the diagnosis of ARDS. Although
In people who do not have clinical immunity to malaria, infection with the malaria parasite could lead to severe complications. We describe a patient who had acute and severe lung injury from malaria. A 37-year-old woman had a 24-hour history of generalized weakness and chills 2 days after returning
BACKGROUND
We present a typical case of adult respiratory distress syndrome (ARDS) occurring during infection with Plasmodium falciparum, in a nonimmune adult. The patient recovered after treatment.
METHODS
A 63-year-old man who had traveled in Kenya without malaria prophylaxis came to the hospital
Among 62 children with mild malaria, cerebral malaria, or severe malarial anemia, we analyzed the transcription of different var gene types. There was no difference in parasitemia level or body temperature between groups. However, a significantly different expression pattern was observed in children
Treatment of cerebral malaria, a complication of the world's most significant parasitic disease, remains problematic due to lack of understanding of its pathogenesis. Metabolic changes, along with cytokine expression alterations and blood cell sequestration in the brain, have previously been
