Objective:
To compare the serum procalcitonin levels and other infection markers released in response to the inflammatory response that develops secondary to the operation in patients with or without type 2 diabetes mellitus who underwent spinal instrumentation.
Methods:
Fifty patients, who belonged to the American Society of Anesthesiologist I-II, were between 18 and 65 years of age, and who had planned for posterior spinal instrumentation surgery were grouped into 2 as group I (n = 25) type 2 diabetic patients (group DM) and group II (n = 25) non-diabetic patients (group non-DM). On the operation day, preoperatively (
T
0
), 5 minutes after intraoperative instrument placement (T
1
), on postoperative 24th hour (T
2
), 48th hour (T
3
), 3rd day (T
4
), 5th day (T
5
), 7th day (T
6
), 10th day (T
7
), and 15th day (T
8
), serum samples were obtained from the patients for the evaluation of procalcitonin, C-reactive protein, erythrocyte sedimentation rate, and neutrophil values.
Results:
Procalcitonin levels were higher in the diabetic patient group at all time points (
P
< .01); C-reactive protein levels were higher in T
1
, T
2
, and T
5
in the diabetic patient group (
P
< .05). There was no difference in erythrocyte sedimentation rate or neutrophil counts between the groups (
P
> .05). When the alterations in procalcitonin levels were compared between diabetic and non-diabetic groups, in diabetic patients, there were significantly higher increases in the first 6 timelines (
P
< .05).
Conclusion:
In diabetic patients, the procalcitonin levels were significantly higher at all time points, predicting an augmented bacterial infection in those patients compared with the non-diabetic patients.
