A genetic score \u22652 had a positive predictive value of 0.31 for having an initial insufficient VRC <jats:italic>C<\/jats:italic><jats:sub>min<\/jats:sub> and initial VRC <jats:italic>C<\/jats:italic><jats:sub>min<\/jats:sub> was not associated with the genetic score. The lack of association between the genetic score and VRC <jats:italic>C<\/jats:italic><jats:sub>min<\/jats:sub> may be related to the inflammatory status of the patients (C\u2010reactive protein [CRP] levels: median [Q1\u2010Q3]: 43.0 [11.0\u2010110.0]\u00a0mg\/L), as multivariate analysis performed on all VRC <jats:italic>C<\/jats:italic><jats:sub>min<\/jats:sub> identified CRP as an independent determinant of the VRC <jats:italic>C<\/jats:italic><jats:sub>min<\/jats:sub> adjusted for dose (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.0001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The combined genetic score did not predict low VRC exposure in patients with inflammation, which is frequent in patients with invasive fungal infections.
