Method for determining the risk of incidence of a care-related infection in a patient

A kit comprising means for amplifying and/or means for detecting the expression of at least one gene encoding a pro-inflammatory cytokine receptor located on chromosome 2 in the region 2q11-2q12, and the expression of at least one biomarker selected from the group consisting of:

• at least one gene selected from the family of genes encoding molecules involved in the innate immune system,
• at least one gene selected from the family of genes encoding molecules of the cell cycle,
• at least one gene selected from the family of genes encoding cytokines, at least one gene selected from the family of genes encoding anti-inflammatory cytokines,
• at least one gene selected from the family of genes encoding pro-inflammatory cytokines,
• at least one gene selected from the family of genes encoding molecules involved in cytoskeleton formation,
• at least one gene selected from the family of genes encoding molecules involved in gene expression and/or transcription,
• at least one gene selected from the family of genes encoding growth factors, and/or
• at least one gene selected from the family of genes encoding molecules of the metabolism,
• at least one gene selected from the family of genes encoding molecules involved in the adaptive immune system,
• at least one gene selected from the family of genes encoding molecules involved in signal transduction,
• at least one gene selected from the family of genes encoding molecules involved in modulation of the acute phase, and
• at least one human endogenous retrovirus (HERV);
• the kit being characterized in that all the amplification and/or detection means of the kit enable the detection and/or amplification of at most 100 biomarkers in total.
