Clinical Trial Summary

The main objective of this study is to characterize the inflammatory proteins, gene polymorphisms, and transcriptome profiles in patients with erythema migrans to gain better insight into pathogenesis of early Lyme borreliosis and to define new immune modulators that could serve as biomarkers of disease activity.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	inflammatory proteins in erythema migrans patients	The inflammatory immune profiles will be assessed using Luminex to measure the expression of cytokines and chemokines representative of innate and adaptive TH1, TH2, TH17, and B cell responses in serum and if available, skin, of patients during active infection and after treatment.	up to 12 months follow-up
Secondary	gene polymorphisms in erythema migrans patients	ImmunoChip single-nucleotide polymorphism array for dense genotyping of rheumtic disease-relevant genomic variants will be used.	at enrollment
