188-OR: Inflammatory and Insulinemic Dietary Patterns Associate with Nephropathy in Type 1 Diabetes (T1D)
Diabetic nephropathy (DN) causes much morbidity and mortality in T1D, necessitating better mechanistic insights for improved prevention and therapy. In addition to hyperglycemia, DN pathogenesis may involve inflammation or insulin resistance, and diets modulating these pathways may impact DN risk. I...

Zusammenfassung: | Diabetic nephropathy (DN) causes much morbidity and mortality in T1D, necessitating better mechanistic insights for improved prevention and therapy. In addition to hyperglycemia, DN pathogenesis may involve inflammation or insulin resistance, and diets modulating these pathways may impact DN risk. In this cross-sectional study, we examined associations of inflammatory and insulinemic potentials of whole diets with DN in a subset of the Joslin 50-year Medalist Study, comprising 570 individuals with T1D >50 years and food frequency questionnaire data. Empirical dietary inflammatory pattern (EDIP) and empirical index for hyperinsulinemia (EDIH) scores were separately derived as weighted sums of foods and beverages previously shown to be predictive of circulating inflammatory biomarkers or C-peptide levels, respectively. In multivariable-adjusted logistic regression models, including age, sex, BMI, exercise, lipids, HbA1c, and hypertension as covariates, 1 S.D. increments in EDIP and EDIH associated with 0.46 (95% CI 0.26-0.84, p=0.01) and 0.31 (95% CI 0.15-0.68, p=0.003) reduced odds of being protected against DN (167 events, CKD-EPI eGFR < 60 ml/min/1.73 m2), respectively. Both scores inversely correlated with continuous eGFR (p=0.03 and 0.0003, respectively). Neither index associated with HbA1c, retinopathy severity, neuropathy or cardiovascular diseases. Both scores positively correlated (p |
