Baseline Cardiovascular Risk Factor Control in Patients With Type 2 Diabetes and Coronary Disease Versus Stroke: Secondary Analysis of Cardiovascular Outcome Trials.

BACKGROUND: Patients with type 2 diabetes (T2D) and cardiovascular disease are at increased risk for recurrent ischemic events. Cardiovascular risk factor control is vital for secondary prevention, but how this compares among individuals with different T2D macrovascular complications is unknown. We aimed to determine if there might be differences in risk factor control in patients with T2D with previous stroke versus coronary artery disease (CAD). METHODS: Cross-sectional analyses were performed on 12 856 patients with T2D with prior history of stroke with or without CAD from 3 diabetes cardiovascular outcome trials: CARMELINA (The Cardiovascular and Renal Microvascular Outcome Study With Linagliptin), EMPA-REG OUTCOME (Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients), and CAROLINA (The Cardiovascular Outcome Study of Linagliptin vs Glimepiride in Type 2 Diabetes). Risk factors at baseline assessed included dyslipidemia, hypertension, smoking, and current antiplatelet/anticoagulant therapy. Control, respectively, was defined as LDL (low-density lipoprotein)-C <100 mg/dL or statin use, systolic blood pressure <140 and diastolic blood pressure <90 mm Hg, not currently smoking, and use of an antiplatelet/anticoagulant medication. The odds ratio of 3 to 4 (or good) versus 0 to 2 (or suboptimal) risk factors controlled was analyzed by logistic regression models. RESULTS: The odds for good versus suboptimal risk factor control in patients with CAD alone was higher than in those with stroke alone across all 3 trials odds ratios (95% CI): CARMELINA, 2.05 (1.67-2.51), EMPA-REG OUTCOME, 2.50 (2.10-2.99), and CAROLINA, 1.63 (1.21-2.20). The respective odds ratios were lower (and rendered nonsignificant in CAROLINA) when cardiovascular risk factor control in patients with both CAD and stroke were compared with those with stroke alone: CARMELINA, 1.45 (1.13-1.87); EMPA-REG OUTCOME, 1.62 (1.25-2.08); and CAROLINA, 1.16 (0.74-1.83). CONCLUSIONS: In contemporary populations of patients with T2D, there was significant discordance in control of cardiovascular risk factors between patients with stroke versus CAD, with the former having less optimal control. The intermediate results in patients with both CAD and stroke suggest that these differences could be related at least in part to clinician factors. REGISTRATION: URL: https://www.

Empagliflozin and Decreased Risk of Nephrolithiasis: A Potential New Role for SGLT2 Inhibition?

CONTEXT: Diabetes mellitus is a risk factor for nephrolithiasis. A recent observational study found that in patients with type 2 diabetes (T2D), SGLT2 inhibitor use was associated with a 49% lower risk of nephrolithiasis compared with GLP-1 receptor agonists. OBJECTIVE: We examined the association between nephrolithiasis and the SGLT2 inhibitor empagliflozin, using existing data from randomized clinical trials. METHODS: We pooled data from 15 081 T2D patients randomized to empagliflozin (n = 10 177) or placebo (n = 4904) from 20 phase I-IV trials, including the large cardiovascular outcome trial, EMPA-REG OUTCOME. Incident urinary tract stone events were captured using a predefined collection of MedRA terms. A sensitivity analysis using a narrower definition was also performed. Incidence rate ratios (IRR) and 95% CIs were calculated using the relative risk estimate, stratified by study. RESULTS: The median exposures to study drug were 543 days (placebo) and 549 days (empagliflozin); 183 patients experienced an incident urolithiasis during follow-up (placebo, 79; empagliflozin, 104), yielding annual incidence rates of 1.01 vs 0.63 events/100 patient-years in the 2 respective groups. The IRR was 0.64 (95% CI, 0.48-0.86), in favor of empagliflozin. In the sensitivity analysis, the results were similar (IRR, 0.62 [95% CI, 0.45-0.85]). CONCLUSION: Compared with placebo, empagliflozin therapy was associated with an approximate 40% reduced risk of urinary tract stone events in T2D patients. The underlying mechanisms are unknown but may involve altered lithogenic profile of the urine. Dedicated randomized prospective clinical trials are warranted to confirm these initial observations in patients with and without T2D.

Multidisciplinary strategies to treat severe hypoglycemia in hospitalized patients with diabetes mellitus reduce inpatient mortality rate: Experience from an academic community hospital.

OBJECTIVE: Severe hypoglycemia (blood glucose < 50 mg/dl) in hospitalized patients with diabetes mellitus is associated with poor outcomes such as increased mortality and readmission rates. We study the effects of system based interventions in managing severe hypoglycemia and its impact on outcomes. RESEARCH DESIGN AND METHODS: We performed retrospective review of pre- and post- intervention study to quantify severe hypoglycemia in patients admitted in the general internal medicine wards with primary or secondary diagnosis of diabetes mellitus based on ICD-9 and ICD-10 codes. We implemented multidisciplinary interventions including standardization of treatment, education of in-patient medical teams and physician notification and feedback immediately after severe hypoglycemia. The endpoints were the comparative analysis of incidence of severe hypoglycemia, in-patient mortality rate, 30-day mortality rate, 30-day readmission rate, recovery time from hypoglycemia, time to next glucose measurements, use of standardized treatment and physician notification rate pre-and post-intervention. RESULTS: The incidence of severe hypoglycemia per patient with diabetes was reduced from 9.6% (233/2416) to 5.6% (202/3607) (p<0.001) post-intervention. The in-patient mortality rate in patients with severe hypoglycemia reduced from 4.1% to 0% (p = 0.019), 30-day mortality rate reduced from 9.8% to 3.8% (p = 0.058) post-intervention. 30-day readmission rate was comparable between pre-intervention (31.7%) and post-intervention (29%) (p = 0.60). In comparison, the mortality and readmission rates of all diabetic patients did not reduce during the same observation periods. Recovery time reduced from 116 (83-161) to 75 (57-102) min (p<0.01), time to next glucose measurement reduced from 39.5 (34-48) to 32 (28-35) min (p<0.01), use of standardized treatment improved from 22.7% (53/233) to 72.2% (146/202) (p<0.001) and physician notification rate increased from 29.2 (68/233) to 84.7% (171/202) post-intervention. CONCLUSIONS: Our study shows that multidisciplinary strategies improves the process of early detection and management of severe hypoglycemia and reduce incidence and in-patient mortality rate.
