To evaluate markers of inflammation, we studied 48 patients with type 1 diabetes [DM1, 23F:25M, 19.9+/-9.8 years and duration of DM of 5 (1-21) years& and 66 non-DM subjects, matched for sex, age, and stages of puberty according to Tanner. C-reactive protein (CRP), alpha1-acid glycoprotein (AGP) and fibrinogen were measured by turbidimetric immunoassay and urinary albumin excretion rate (AER) was determined in timed overnight urine samples by RIA. Microalbuminuria was defined when two out of three urine samples had AER ranging 20-200 microg/min. Retinopathy was evaluated by indirect ophthalmoscopic in DM patients. The CRP and AGP levels were higher in DM1 patients as compared to controls, respectively [0.23 (0.01-2.90) vs. 0.14 (0.01-2.41) mg/dl, p= 0.0172& and [53.5 (37-115) vs. 40 (19-78) mg/dl, p< 0.0001]. Fibrinogen levels were not different between both groups. Stepwise multiple regression analysis showed that HbA1c and plasma glucose were the independents predictive variables of AGP, respectively (r2= 0.26; p< 0.05 and r2= 0,29; p< 0,05); CRP and fibrinogen did not correlate significantly with the independents variables. PCR correlate with HbA1c (r= 0.18; p= 0.05) by Pearson's correlation. In conclusion, CRP and AGP were higher in DM1 patients, without microalbuminuria, retinopathy and clinical macrovascular disease. Prospective studies must be addressed to determine the influence of AGP and CRP in the development of chronic complications.

Diabetic nephropathy (DN) is a long-term complication of diabetes mellitus that leads to end-stage renal disease. Microalbuminuria is used for the early detection of diabetic renal damage, but such levels do not reflect the state of incipient DN precisely in type 2 diabetic patients because microalbuminuria develops in other diseases, necessitating more accurate biomarkers that detect incipient DN. Isobaric tags for relative and absolute quantification (iTRAQ) were used to identify urinary proteins that were differentially excreted in normoalbuminuric and microalbuminuric patients with type 2 diabetes where 710 and 196 proteins were identified and quantified, respectively. Some candidates were confirmed by 2-DE analysis, or validated by Western blot and multiple reaction monitoring (MRM). Specifically, some differentially expressed proteins were verified by MRM in urine from normoalbuminuric and microalbuminuric patients with type 2 diabetes, wherein alpha-1-antitrypsin, alpha-1-acid glycoprotein 1, and prostate stem cell antigen had excellent AUC values (0.849, 0.873, and 0.825, resp.). Moreover, we performed a multiplex assay using these biomarker candidates, resulting in a merged AUC value of 0.921. Although the differentially expressed proteins in this iTRAQ study require further validation in larger and categorized sample groups, they constitute baseline data on preliminary biomarker candidates that can be used to discover novel biomarkers for incipient DN.
