Brief summary

Cost-utility analysis during antibiotic treatment (intention-to-treat): Absolute treatment costs during the acute treatment period of 6 or 12 weeks of antibiotics in the two treatment groups, assessed in relation to quality-adjusted life years (QALYs).

Detailed description

Cost-utility analysis after one-year of follow-up (per protocol): Long-term health economics and patient-experienced quality of life, incorporating long-term effects and any late complications or recurrence within the first year., Physical activity: Average daily activity during the treatment period (6 or 12 weeks), recorded using an activity tracker., Tissue concentration: Standard pharmacokinetic parameters (e.g., AUC/MIC, T>MIC, AUC, T½, Cmax, Tmax) in bone tissue, subcutaneous tissue, and plasma., Gut response: Gut microbiome diversity profile and resistome, including AMR genes., Immune response: Standard histological examination of HE stains with quantification of the infiltration of neutrophil granulocytes, macrophages, and lymphocytes. In addition, histological identification of specific genes and proteins involved in inflammatory and immune-regulatory pathways.
