The onset of postoperative septic complications has been associated to serum levels of interleukin (IL) IL-6 and IL-10. [1, 2]. We have extrapolated a diabetic group from a previous study to evaluate pre and postoperative profiles of some inflammatory markers (IL-6 , IL-10 and CRP). We related the data obtained to the onset of postoperative complications. Diabetic patients have been selected because of their high rate of post-operative complications, especially surgical wound infection.

Materials and methods

We evaluated 15 patients, 6 males and 9 females, aged ≥ 70 (range 70-83). The preoperative criterium for inclusion was non urgent major abdominal surgery and a diabetes diagnosis, the exclusion criteria were: urgent abdominal surgery, therapy with steroid and/or immunosuppressor drugs during the 30 days before admission. For each patient we collected three peripheral venous blood samples, at preoperative time 0 (t0), and then at first (t1) and seventh (t2) postoperative day. Cytokine evaluation was obtained by the ELISA method with the “sandwich” tecnique. Among the latter we considered: surgical wound infection; urinary tract infection; respiratory infection / respiratory failure; SIRS and/or sepsis; anastomotic leakage; peritonitis.


We observed 4 complications corresponding to 26,6% of all evaluated patients (Table 1).

All subjects at (t1) showed an elevation of IL-6 levels, more consistent in the complicated ones (140.25 ± 100.89 pg/ml vs 91.54 ± 31.75 pg/ml) (Figure 1). IL-1 showed lower basic levels (t0) in complicated patients (14.54 ± 12.64 pg/ml vs 12 ± 10.70 pg/ml) and also in (t1) (26,36 ± 31,43 pg/ml vs 14,75 ± 7,41 pg/ml ) (Figure 2). The CRP values didn’t differ at any time between the two groups (Figure 3).

In the group of elderly diabetic patients observed, so as in the general population, according to published data [1], IL-6 and IL-10 may be referred as prognostic markers with regard to postoperative complication. It would be moreover useful to identify a cut-off value to select the subjects with a higher postoperative risk.
