Association of kidney disease measures with risk of renal function worsening in patients with type 1 diabetes

Background: Albuminuria has been classically considered a marker of kidney damage progression in diabetic patients and it is routinely assessed to monitor kidney function. However, the role of a mild GFR reduction on the development of stage 653 CKD has been less explored in type 1 diabetes mellitus (T1DM) patients. Aim of the present study was to evaluate the prognostic role of kidney disease measures, namely albuminuria and reduced GFR, on the development of stage 653 CKD in a large cohort of patients affected by T1DM. Methods: A total of 4284 patients affected by T1DM followed-up at 76 diabetes centers participating to the Italian Association of Clinical Diabetologists (Associazione Medici Diabetologi, AMD) initiative constitutes the study population. Urinary albumin excretion (ACR) and estimated GFR (eGFR) were retrieved and analyzed. The incidence of stage 653 CKD (eGFR < 60 mL/min/1.73 m2) or eGFR reduction > 30% from baseline was evaluated. Results: The mean estimated GFR was 98 \ub1 17 mL/min/1.73m2 and the proportion of patients with albuminuria was 15.3% (n = 654) at baseline. About 8% (n = 337) of patients developed one of the two renal endpoints during the 4-year follow-up period. Age, albuminuria (micro or macro) and baseline eGFR < 90 ml/min/m2 were independent risk factors for stage 653 CKD and renal function worsening. When compared to patients with eGFR > 90 ml/min/1.73m2 and normoalbuminuria, those with albuminuria at baseline had a 1.69 greater risk of reaching stage 3 CKD, while patients with mild eGFR reduction (i.e. eGFR between 90 and 60 mL/min/1.73 m2) show a 3.81 greater risk that rose to 8.24 for those patients with albuminuria and mild eGFR reduction at baseline. Conclusions: Albuminuria and eGFR reduction represent independent risk factors for incident stage 653 CKD in T1DM patients. The simultaneous occurrence of reduced eGFR and albuminuria have a synergistic effect on renal function worsening

Proteomic analysis of platelets treated with gamma irradiation versus a commercial photochemical pathogen reduction technology.

BACKGROUND: Several strategies are currently being tested to reduce the risk of pathogen transmission associated with platelet (PLT) transfusion. Within the framework of the Italian Platelet Technology Assessment Study, we investigated the variations of the protein profiles (proteomics) of apheresis PLT concentrates (PCs) upon treatment with riboflavin and ultraviolet (UV) light (Mirasol; 6.24J/mL; 280-400nm). STUDY DESIGN AND METHODS: Control, gamma-irradiated, and Mirasol-treated apheresis PCs were assayed on Days 1 and 5 of storage by means of gel-based analytical approaches (two-dimensional gel electrophoresis) and mass spectrometry-based identification of significant (p<0.05 analysis of variance) differential proteins. Supernatants were then assayed for metabolism and oxidative stress-related metabolites through multiple reaction monitoring mass spectrometry. RESULTS: Only a handful of modifications could be observed in the PLT proteome profiles in response to the Mirasol treatment, which included proteins involved in oxidative stress responses, PLT metabolism, and activation. Results confirmed increased metabolic rate and oxidative stress in the supernatants of treated PLTs (both gamma irradiated and Mirasol treated). CONCLUSION: From this investigation, it emerges that, from a proteomics standpoint, gamma irradiation results in the acceleration of PLT storage lesions and the Mirasol treatment only moderately exacerbates these phenomena
