Serum Levels of Insulin-Like Growth Factor 1, Interlukin-6, Heat-Shock Proteins-27 and Heat-Shock Proteins-60 as Inflammatory Markers of Type 2 Diabetes: A Case-Control Study

Abstract

Background: Inflammatory biomarkers such as insulin-like growth factor 1 (IGF-1), interleukin 6 (IL-6), and heat-shock proteins 27 (HSP-27) and 60 (HSP-60) may contribute to the development of type II diabetes mellitus. This study aimed to compare these inflammatory biomarkers among individuals with and without type II diabetes mellitus. Methods: This case-control study was conducted on fifty patients with type II diabetes mellitus and fifty individuals without it. None of the participants suffered from inflammatory diseases like rheumatoid arthritis and systemic lupus erythematosus. Patients in the diabetic group were matched with individuals in the non-diabetic group respecting their age and gender. Serum levels of IGF-1, IL-6, HSP-27, and HSP-60 were measured through enzyme-linked immunosorbent assay kits. Data were analyzed using the SPSS software (v. 15.0). Results: The mean serum levels of IGF-1, IL-6, HSP-27, and HSP-60 in the diabetic group were significantly greater than the non-diabetic group (P < 0.05). Conclusions: This study shows that IGF-1, IL-6, HSP-27, and HSP-60 inflammatory markers play roles in the development of type II diabetes mellitus.
