Outcome Measures

Primary Outcomes (1)

  • Prevalence of anemia during hospitalization

    Diagnosis of anemia through WHO/NCI criteria for anemia and severity of anemia at time of diagnosis, 1-4 weeks after initiation of relevant treatment and up to 6 months after discharge

    From time of diagnosis/intervention untill end of follow-up (up to 6 months from inclusion)

Secondary Outcomes (3)

  • Prevalence of iron deficiency anemia in patients with IE and relevant controls

    From time of diagnosis/intervention untill end of follow-up (up to 6 months from inclusion)

  • Prevalence of anemia due to inflammation in patients with IE and relevant controls

    From time of diagnosis/intervention untill end of follow-up (up to 6 months from inclusion)

  • Time untill resolution of inflammation and anemia in patients with IE and relevant controls

    From time of diagnosis/intervention untill end of follow-up (up to 6 months from inclusion)

Study Arms (4)

Endocarditis

100 patients diagnosed with infectious endocarditis according to DUKE criteria. Detailed characterization of inflammation, anemia and markers of iron hemostatis will be made at diagnosis and followed undtill 6 months after discharge.

Other: Measurement of biomarkers for inflammation and anemia

TAVI/TEVAR patietns

30 patients undergoing elektive TAVI/TEVAR procedures. Detailed characterization of inflammation, anemia and markers of iron hemostatis will be made at directly prior to procedure and followed undtill 3 months after discharge.

Other: Measurement of biomarkers for inflammation and anemia

Patients with bacterial infections without endocarditis

30 patients diagnosed with with bacterial infections, without endocarditis. Detailed characterization of inflammation, anemia and markers of iron hemostatis will be made at diagnosis and followed undtill 3 months after discharge.

Other: Measurement of biomarkers for inflammation and anemia

Healthy blood donors

Detailed characterization of inflammation, anemia and markers of iron hemostatis will be made at directly prior to blood donation and approximately 1 week after blood donations

Other: Measurement of biomarkers for inflammation and anemia

Interventions

Measurement of biomarkers for inflammation and anemia, in addition to standart clinical measurements
