Vitreous fluid and serum were obtained at the time of vitrectomy from 15 subjects with diabetic proliferative retinopathy and 6 control subjects. The mean serum IGF-I (IGF-I level: 1 nM/l = 7.7 ng/ml) concentrations were 15.40 +/- 4.97 nM/l in controls and 16.24 +/- 4.32 nM/l in diabetic patients. The mean vitreous IGF-I concentration was 1.05 +/- 0.30 nM/l in controls and 0.91 +/- 0.50 nM/l in diabetic patients. There were no significant differences between the two groups, and serum IGF-I concentrations were not correlated with vitreous IGF-I concentrations in the patients with diabetic proliferative retinopathy. These data suggest that IGF-I may not be a risk factor for the development of proliferative diabetic retinpathy.

UI MeSH Term Description Entries
D007334 Insulin-Like Growth Factor I A well-characterized basic peptide believed to be secreted by the liver and to circulate in the blood. It has growth-regulating, insulin-like, and mitogenic activities. This growth factor has a major, but not absolute, dependence on GROWTH HORMONE. It is believed to be mainly active in adults in contrast to INSULIN-LIKE GROWTH FACTOR II, which is a major fetal growth factor.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation. Radioimmunoassays
