Chemotherapy-induced pain is a dose-limiting condition that affects 30% of patients undergoing chemotherapy. We found that the gut microbiota promotes the development of chemotherapy-induced mechanical hyperalgesia. Oxaliplatin-induced mechnical hyperalgesia was reduced in germ-free mice and in those mice pretreated with antibiotics. Restoration of the microbiota of germ-free mice abrogated this protection. These effects appear to be mediated, in part, by TLR4 expressed on hematopoietic cells, including macrophages.

A combination of low mood and high AS may act as a psychological diathesis for the development of persisting PC symptoms. Early identification could provide a focus for early intervention to prevent the development of postconcussion syndrome after mTBI.
