Patients were divided into two as patients with collum femoris fractures (group 1; n=23) and intertrochanteric fractures (group 2; n=37).
The main findings of our study are increased Kyn/Trp ratio in patients with hip fracture with respect to healthy subjects and in patients with intertrochanteric fracture when compared to those with collum femoris fracture.
In accordance with this study, the increased ratio of Kyn to Trp in patients with collum femoris fracture might indicate an osteoblastogenesis with better progress of fracture.
26) The increased ratio of Kyn/Trp in both fracture patients, which was higher in collum femoris patients than in intertrochanteric fracture patients, may be related with host immune response.
