Abstract

The elevation of insulin-like growth factor 1 (IGF-1) and adipokine retinol-binding protein 4 (RBP-4) is known to be associated with the risk of many cancers. The aim of this study was to evaluate the serum concentrations of IGF-1 and RBP-4 in patients with PDAC and chronic pancreatitis (CP). The study included 43 patients with PDAC, 39 patients with CP and 10 controls. The concentrations of IGF-1 and RBP-4 were obtained using the ELISA method (Corgenix UK Ltd R&D Systems). The study protocol was approved by the Bioethics Committee at the Medical University of Lodz. In PDAC patients the serum IGF-1 level was significantly higher than in patients with CP (107.79 ± 66.40 ng/ml vs 89.91 ± 74.06 ng/ml; P < 0.05). Patients with both CP and diabetes mellitus (DM) were noted to have a significantly lower level of IGF-1 compared with those who only had CP (51.33 ± 24.30 ng/ml vs 108.42 ± 82.39 ng/ml; P = 0.01). The same result was obtained for men with and without DM (58.05 ± 32.44 ng/ml vs 98.79 ± 79.47 ng/ml, P = 0.05). As regards the serum level of RBP-4, the PDAC and CP groups were not significantly different from each other. Diabetes accompanying PDAC does not influence the level of IGF-1 as opposed to diabetes in the course of CP...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
