DEFRONZO, San Antonio, TX, Austin, TX data and case reports for older sulfonylureas which are rarely used. In this Acute and Chronic Severe hypoglycemia remains a significant unmet medical need in study, we investigated hospitalization events for hypoglycemia among elderly patients with diabetes. Currently approved rescue products (Lilly Glucagon Americans with diabetes with concomitant glipizide and warfarin use.

Diabetes Trial (VADT) Supported By: NIDDK (5R44DK085809-03) ARAMESH SAREMI, DERRICK KAUFMAN, DAWN C. SCHWENKE, PETER D. REAVEN, FOR THE VADT, Phoenix, AZ, Hines, IL We have previously shown that the effect of intensive glycemic control on 2-LB CVD outcomes differed across major race/ethnic groups in VADT. We now Different Clinical Predictors of Nonsevere and Severe Hypoglycemia determined whether the frequency of hypoglycemic episodes in response to this during Treatment with Glargine or Standard Care in the ORIGIN therapy differed across major race/ethnic groups. The total numbers of interim Trial hypoglycemia episodes with symptoms were reported at each visit. The current MATTHEW C. RIDDLE, HERTZEL GERSTEIN, HYEJUNG JUNG, LARS E. RYDÉN, analysis included 1096 non-Hispanic Whites (NHW), 303 non-Hispanic Blacks LINDA MELLBIN, JULIO ROSENSTOCK, JEFFREY PROBSTFIELD, Portland, OR, (NHB) and 303 Hispanics (His).

We analyzed data from 12,537 with NHB and His, respectively. Very similar patterns were seen for severe participants to identify baseline and on-treatment factors associated with and nocturnal hypoglycemia. Although intensive treatment was a significant symptomatic hypoglycemia confirmed by glucose 3 mmol/L or (separately) ≤ predictor of hypoglycemic events, there was no interaction between treatment severe hypoglycemia.

Independent ≥ the risk/benefit ratio for intensive glycemic control differs between major race/ predictors of events as time-varying covariates were assessed by Cox ethnic groups in the VADT. proportional hazard models including baseline characteristics, treatment allocation, and mean on-treatment A1C. Sulfonylurea use (Hazard Ratio [HR] 2.07 for non-severe, 1.35 for severe) and glargine treatment (HR 4.53 for non-severe, 3.57 for severe) were independently associated with higher risk in both categories. Risk of non-severe events was lower with older age (HR [95%CI] 0.98 [0.98-0.99]) and higher BMI (HR 0.97 [0.96-0.98]), and higher with presence of diabetes (HR 1.52 [1.21-1.92] and higher baseline A1C (HR 1.24 [1.14-1.35]). Risk of severe events was higher with older age (HR 1.04 [1.03-1.06]), hypertension (HR 1.51 [1.14-2.00]), higher serum creatinine (HR 1.01 [1.01-1.02]); lower with higher MMSE score (HR 0.96 [0.93-0.99]); and unrelated to baseline glycemic status. With glargine treatment, risk of both non-severe and severe events was higher at lower on-treatment A1C; with standard care risk of severe events increased at higher A1C. Conclusions: Overall incidences of hypoglycemia were low. Sulfonylurea and glargine are associated with both non-severe and severe events, but other independent predictors differ between categories. Non-severe and severe events affect Supported By: ADA (1-06-CR-32); NIH (R01067690, R01HL094775) different people and occur in different settings.
