Bacteremia is a severe bacterial infection with significant mortality. Clinical parameters that reliably predict it are less elucidated. We assessed the potential of serum adhesion molecules for predicting bacteremia and compare it with current available infection biomarkers to determine a more timely predictor of adult severe sepsis patients on admission to the emergency department (ED). ⋯ Although serum cell adhesion markers are not specific for predicting bacteremia in septic patients, higher mean serum cell adhesion molecules levels on admission may imply both more severe infection and presence of bacteremia. Assay of serum adhesion molecules may be added as an infectious marker among the panel of bacteremic parameters in clinical practice, especially since early diagnosis and prompt antimicrobial therapy are essentially for survival.

Autoantibodies against the M-type phospholipase A2 receptor (PLA2R1) are specific markers for primary membranous nephropathy (pMN) and anti-PLA2R1 serum levels may be useful to monitor disease activity. So far, a recombinant cell-based indirect immunofluorescence assay (RC-IFA) using recombinant PLA2R1 as a substrate has been widely available but lacks a finely graduated assessment of antibody concentrations. ⋯ The results demonstrate that the new test system is qualified for routine use and that it has an almost perfect agreement with both, the clinical characterization of the patients and the results generated with RC-IFA.
