Abstract

Aim: The study aimed to investigate whether imbalanced iron status in patients with haemodialysis coexisted with abnormal lipid profile, higher inflammatory status and altered growth hormone-insulin-like growth factor (GH-IGF)-I axis and to compare these biochemical markers with patients with ischaemic heart disease. Methods: Serum samples for biochemical and immunological analyses were collected from 74 normal subjects, 138 patients with ischaemic heart disease (IHD) and 115 patients on haemodialysis (HD). Results: Compared with normal subjects, lower serum iron, lower total iron-binding capacity (TIBC) and higher ferritin in HD patients coexisted with decreases in high-density lipoprotein cholesterol and total bilirubin as well as increases in lactate dehydrogenase (LDH), interleukin (IL)-6, C-reactive protein (CRP) and IL-10. Decreased IGF-I and increased GH were found in HD patients whereas unchanged GH-IGF axis were found in IHD patients. Compared with IHD, much higher ferritin, lower TIBC, lower bilirubin and higher LDH levels were found in HD patients. Conclusion: Imbalanced iron status in patients on HD coexisted with abnormal lipid profiles, increased anaerobic activity and higher inflammatory status, which suggests that imbalanced iron status in HD patients may play a deleterious role in cardiovascular pathophysiology. Altered GH-IGF axis found in HD patients was more obvious than in IHD patients. This may imply that the GH-IGF axis system is modulated or adapted by HD.
