      Background - Several inflammatory molecules participate in the immune response to malaria. Interleukin (IL)-18 is an inflammatory cytokine activated by NLRP3 inflammasomes. In clinical falciparum malaria, with and without HIV co-infection, data on IL-18 and in particular on its binding protein, IL-18bp, is scarce.<p> <p>Methods - Clinical data and blood samples were collected from adults in ...
    • Plasma levels of interleukin 27 in falciparum malaria is increased independently of co-infection with HIV: Potential immune-regulatory role during malaria

      <i>Background</i> - The immune response during falciparum malaria mediates both harmful and protective effects on the host; however the participating molecules have not been fully defined. Interleukin (IL)-27 is a pleiotropic cytokine exerting both inflammatory and anti-inflammatory effects, but data on IL-27 in malaria patients are scarce.<p><p> <i>Methods</i> - Clinical data and blood samples ...
    • Plasma parasitemia as assessed by quantitative PCR in relation to clinical disease severity in African adults with falciparum malaria with and without HIV co-infection

      <p><i>Purpose - </i>When considering malaria disease severity, estimation of parasitemia in erythrocytes is important, but sometimes misleading, since the infected erythrocytes may be sequestered in peripheral capillaries. In African children and Asian adults with falciparum malaria, parasitemia as assessed by quantitative PCR (qPCR) in plasma seems to be a valuable indicator of disease severity, ...
    • Soluble markers of neutrophil, T-cell and monocyte activation are associated with disease severity and parasitemia in falciparum malaria 

      Otterdal, Kari; Berg, Åse; Michelsen, Annika; Patel, Sam; Tellevik, Marit Gjerde; Haanshuus, Christel Gill; Fevang, Børre; Aukrust, Pål; Langeland, Nina; Ueland, Thor (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-18)
      <i><p>Background</i>: The immune response during P. falciparum infection is a two-edged sword, involving dysregulation of the inflammatory responses with several types of immune cells participating. Here we examined T-cell, monocyte/macrophage and neutrophil activation during P. falciparum infection by using soluble activation markers for these leukocyte subsets.</p> <i><p>Methods</i>: In a ...
