AIMS: To investigate alterations of insulin resistance (IR), chronic inflammation and urine albumin-to-creatinine ratio (ACR) in Chinese community-based prediabetic population. MATERIALS AND METHODS: 252 prediabetics [prediabetes (PD), including impaired fasting glucose (IFG), 91; impaired glucose tolerance (IGT), 123; IFG+IGT, 38] and 38 newly diagnosed-diabetics (NDDM) aged over 35 years older were screened from 2336 community individuals. 123 age and gender matched individuals with normal glucose tolerance (NGT) were selected as controls. Serum adiponectin, interleukin-6 (IL-6) levels and urine ACR were determined, HOMA-IR and Gutt's index were calculated to evaluate IR and insulin sensitivity, respectively. RESULTS: The data displayed significant difference of serum adiponectin, IL-6, ACR and Gutt's index among PD, NDDM and NGT groups. Adiponectin level and Gutt's index decreased, but IL-6 level and ACR increased gradually among NGT, PD and NDDM groups (P<0.01). Unlike adiponectin and IL-6, ACR analysis indicates a gradual increase from NGT, IFG, IGT, IFG+IGT to NDDM individuals (P<0.01). Gutt's index showed significant difference between IFG and NDDM, IFG+IGT and NDDM (P<0.01), but HOMA-IR index did not. CONCLUSIONS: IR, chronic inflammation and endothelial dysfunction dose exist in prediabetic individuals, especially in IFG+IGT population. Gutt's index and ACR might seem to be more sensitive than adiponectin and HOMA-IR index as IR and chronic inflammation maker in prediabetic population.
