Tetrahydrobiopterin (BH₄) is a co-factor required for catalytic activity of nitric oxide synthase (NOS) and amino acid-monooxygenases, including phenylalanine hydroxylase. BH4 is unstable: during oxidative stress it is non-enzymatically oxidized to dihydrobiopterin (BH₂), which inhibits NOS. Depending on BH₄ availability, NOS oscillates between NO synthase and NADPH oxidase: as the BH₄/BH₂ rati...
ABSTRACT
 Malaria is a tropical infectious disease with high morbidity and mortality rates. In malaria, various kinds of haematological complications can arise, one which thrombocytopenia. Thrombocytopenia most commonly encountered during acute malaria infection varying degrees observed in both Plasmodium falciparum vivax infections. The purpose this study was to determine the relationship...
Oxidative stress plays an important role in the pathogenesis of falciparum malaria, a disease still claiming close to 1 million deaths and 200 million new cases per year. Most frequent complications are severe anemia, cerebral malaria, and immunodepression, the latter being constantly present in all forms of malaria. Complications are associated with oxidative stress and lipoperoxidation. Its f...
BACKGROUND Severe anaemia in children with cerebral malaria has been associated with respiratory distress secondary to lactic acidosis and/or hypoxia. The ensuing metabolic derangement may further depress the level of consciousness culminating in presentation with profound coma. This association has poorly been studied. OBJECTIVE To determine the relationship between profound coma at presenta...
BACKGROUND Severe falciparum malaria with human immunodeficiency virus (HIV) coinfection is common in settings with a high prevalence of both diseases, but there is little information on whether HIV affects the clinical presentation and outcome of severe malaria. METHODS HIV status was assessed prospectively in hospitalized parasitemic adults and children with severe malaria in Beira, Mozambi...
Young infants are less susceptible to severe episodes of malaria but the targets and mechanisms of protection are not clear. Cord blood antibodies may play an important role in mediating protection but many studies have examined their association with the outcome of infection or non-severe malaria. Here, we investigated whether cord blood IgG to Plasmodium falciparum merozoite antigens and anti...
Occasionally, malaria may present with unusual signs and symptoms. We report a case of an uncommon presentation of Plasmodium falciparum infection in a 59-year-old Ethiopian immigrant, which initially presented with hyperglycaemia and multiple organ dysfunction syndrome (MODS). Reports of unusual presentations of malaria are few and cases of severe malaria with hyperglycaemia are rarely describ...
BACKGROUND In Tanzania, malaria is the major cause of morbidity and mortality, accounting for about 30% of all hospital admissions and around 15% of all hospital deaths. Severe anaemia and cerebral malaria are the two main causes of death due to malaria in Tanga, Tanzania. METHODS This was a prospective observational hospital-based study conducted from October 2004 to September 2005. Consent ...
