Özet

Background/aims: Somatostatin receptors have been shown on hepatic stellate cells, and somatostatin infusion has been shown to inhibit hepatic stellate cells activation. We aimed to test the effects of a long-acting somatostatin analogue, lanreotide, on bile duct ligation- induced liver fibrosis in rats. Methods: Thirty-seven Wistar rats were divided into 5 groups as follows: Group 1, bile duct ligation+lanreotide; Group 2, bile duct ligation; Group 3, sham+lanreotide; Group 4, sham; and Group 5, control group. Lanreotide-autogel (20 mg/kg/month) or saline in intraperitoneal doses was administered. Serum biochemical parameters, liver collagen level, and oxidative stress and histological parameters were determined after 28 days. Results: The tissue collagen level, biochemical parameters (AST, ALT, bilirubins, alkaline phosphatase, gamma-glutamyl transpeptidase) and oxidative stress parameters (malondialdehyde, luminal, lucigenin) in the bile duct ligation groups were higher than in the sham-operated and control groups (p<0.001 for all). Lanreotide improved malondialdehyde and glutathione levels in the bile duct ligation+lanreotide group. In histopathological examination, bile duct ligation groups showed stage-3 liver fibrosis, while all the controls were normal. Lanreotide did not improve the liver fibrosis histologically or biochemically. Conclusions: A monthly active somatostatin analogue, lanreotide, improved malondialdehyde and glutathione; however, it was not able to improve bile duct ligation-induced liver fibrosis in rats. Although lanreotide is a long-acting medication, it did not show anti-fibrotic effects in the model.
