Objectives: to evaluate the plasma IL-10 levels during elective operative r
epair of thoraco-abdominal and abdominal aortic aneurysm repair. To study w
hether IL-10 plasma levels ae associated wit the duration of cross-clamping
(ischaemia) and clinical outcome.
Materials: fifteen consecutive patients undergoing surgery for TAAA and 10
consecutive patients undergoing surgical repair of AAA were included.
Methods: plasma concentrations of IL-10 were measured by ELISA technique. C
linical outcome of the TAAA patients was prospectively analysed.
Results: during aortic clamping IL-10 was produced in both populations. The
plasm IL-10 peak (934 +/- 172 pg/ml) of the TAAA group was seen at 4 h aft
er declamping and remained detectable after 48 h. The plasma IL-10 peak (21
2 +/- 32 pg/ml) of the AAA group was seen 30 min after declamping and fell
to undetectable levels by 24 h. These data show that the peak IL-10 plasma
levels in TAAA repair are significantly (p < 0.05) higher compared to the p
eak IL-10 plasma levels as seen during AAA repair. A positive correlation w
as seen between cross-clamping and peak plasma IL-10 and organ dysfunction.
Conclusions: IL-10 plasma concentrations appear higher, later and are longe
r detectable in patients undergoing TAAA. Correlations were seen with durat
ion of cross-clamping and MSOD.
