BACKGROUND: Inflammation and oxidative stress (OxS) contribute to the
pathogenesis of diabetic kidney disease (DKD) and contrast-induced nephropathy
(CIN). Patients with DKD were found to be more prone to CIN. Interleukin-33
(IL-33) is a proinflammatory cytokine, but its role in DKD and CIN is unknown.
METHODS: Thirty male Sprague-Dawley rats were enrolled. The first group was
comprised of healthy rats (HRs), whereas the other four groups were made up of
diabetic rats (DRs), diabetic rats with contrast-induced nephropathy (CIN + DRs),
melatonin-treated diabetic rats (MTDRs), and melatonin-treated CIN + DRs (MTCIN +
DRs). All groups except the HRs received 50?mg/kg/day streptozotocin (STZ). CIN +
DRs were constituted by administrating 1.5?mg/kg of intravenous radiocontrast dye
on the 35th day. MTDRs and MTCIN + DRs were given 20?mg/kg/day of intraperitoneal
injection of melatonin (MT) from the 28th day for the constitutive seven days.
RESULTS: We observed increased IL-33 in the kidney tissue following induction of
CIN in DRs. To determine whether MT is effective in preventing CIN, we
administered MT in CIN + DRs and demonstrated that kidney tissue levels of OxS
markers, inflammatory cytokines, and IL-33 were significantly diminished in MTCIN
+ DRs compared with other groups without MT treatment (p < 0.05). CONCLUSION:
Inhibition of IL-33 with MT provides therapeutic potential in DKD with CIN.
