Abstract
Background
Liver cirrhosis is considered the terminal stage of many hepatic diseases of different etiologies. Liver cirrhosis was associated with increased incidence rates of some extrahepatic manifestations such as osteoporosis. Regardless of the liver disease etiology, the presence of cirrhosis implies a twofold risk of bone fractures higher than non-cirrhotic patients. The liver is the main storage depot for iron and is the primary organ that is responsible for clearing excess iron in conditions of iron overload. When the iron storage and antioxidant capacity of the liver is overwhelmed, iron overload can lead to marked oxidantmediated liver and bone injury and iron overload was a risk factor for osteoporosis via affecting osteoblast survival.
Aim of the work
to examine the possible protective effect of Deferoxamine (DFO) on liver cirrhosis rat model induced osteoporosis.
Material and Method
rats was divided into 4 groups Animal Groups: Naïve control, DFO-treated group, TAA-treated group received Thioacetamide (TAA) ip (200 mg/kg/rat) twice weekly for 12 weeks, TAA+DFO treated group received TAA intra-peritoneal in addition to DFO intraperitoneal injections (300 mg/kg/3 times/week, for the last 4 weeks of TAA injections.
Results and Conclusion
Deferoxamine produced significant improvement in bone mineralization alongside its significant effect on liver function test in a rat model of liver cirrhosis induced osteoporosis.
