Among patients with diabetes and stable ischemic heart disease, higher SYNTAX scores predict higher rates of major cardiovascular events and were associated with more favorable outcomes of revascularization compared with medical therapy among patients suitable for CABG. (Bypass Angioplasty Revascularization Investigation in Type 2 Diabetes; NCT00006305).
Background. Research has shown less aggressive treatment and poorer control of cardiovascular disease (CVD) risk factors in women than men. Methods. We analyzed sex differences in pharmacotherapy strategies and attainment of goals for hemoglobin A1c (HbA1c), blood pressure (BP), and low density lipoprotein cholesterol (LDL-C) in patients with type 2 diabetes and established coronary artery disease enrolled into the BARI 2D trial. Results. Similar numbers of drugs were prescribed in both women and men. Women were less frequent on metformin or sulfonylurea and more likely to take insulin and to be on higher doses of hydroxymethylglutaryl-CoA reductase inhibitors (statins) than men. After adjusting for baseline differences and treatment prescribed, women were less likely to achieve goals for HbA1c (OR = 0.71, 95% CI 0.57, 0.88) and LDL-C (OR = 0.64, 95% CI 0.53, 0.78). More antihypertensives were prescribed to women, and yet BP ≤ 130/80 mmHg did not differ by sex. Conclusions. Women entering the BARI 2D trial were as aggressively treated with drugs as men. Despite equivalent treatment, women less frequently met targets for HbA1c and LDL-C. Our findings suggest that there may be sex differences in response to drug therapies used to treat diabetes, hypertension, and hyperlipidemia.
Objective To describe a case of hepatomegaly and elevated transaminases in a patient with glycogenic hepatopathy (GH) as a complication of uncontrolled diabetes. Methods Clinical, laboratory, and pathological information are described. Results An 18-year-old male with uncontrolled type 1 diabetes and recurrent diabetic ketoacidosis (DKA) presented with abdominal distention and severe hyperglycemia. Physical examination revealed massive hepatomegaly. Laboratory evaluation showed anion-gap metabolic acidosis, ketonuria, and markedly elevated aspartate and alanine amino transaminases (AST = 1,162 IU/L and ALT = 598 IU/L, respectively). Despite resolution of DKA with insulin infusion, transaminases continued to increase (peak AST = 3,725 U/L, ALT = 1,049 U/L) with no signs of liver failure (normal coagulation profile and albumin level). Abdominal ultrasonography revealed an enlarged liver with moderate echogenicity, consistent with steatosis. Extensive evaluation for causes of hepatitis including toxic, autoimmune, genetic, and infectious diseases was unrevealing. Liver biopsy showed no signs of nonalcoholic fatty liver disease (NAFLD), such as fibrosis, steatosis, or portal inflammation. However, swollen hepatocytes with glycogen accumulation consistent with GH were seen. Conclusion GH can present as hepatomegaly and elevated liver transaminases in patients with uncontrolled diabetes. Clinicians should consider GH in patients with uncontrolled diabetes after ruling out other common causes. Liver ultrasound cannot differentiate this condition from the more commonly seen NAFLD. Although liver biopsy remains a gold standard, evaluation with magnetic resonance imaging may be considered as a less invasive alternative in the appropriate clinical setting.
ImportanceType 2 diabetes (T2D) is the leading cause of kidney disease in the US. It is not known whether glucose-lowering medications differentially affect kidney function.ObjectiveTo evaluate kidney outcomes in the Glycemia Reduction Approaches in Diabetes: A Comparative Effectiveness (GRADE) trial comparing 4 classes of glucose-lowering medications added to metformin for glycemic management in individuals with T2D.Design, Setting, and ParticipantsA randomized clinical trial was conducted at 36 sites across the US. Participants included adults with T2D for less than 10 years, a hemoglobin A1c level between 6.8% and 8.5%, and estimated glomerular filtration rate (eGFR) greater than or equal to 60 mL/min/1.73 m2 who were receiving metformin treatment. A total of 5047 participants were enrolled between July 8, 2013, and August 11, 2017, and followed up for a mean of 5.0 years (range, 0-7.6 years). Data were analyzed from February 21, 2022, to March 27, 2023.InterventionsAddition of insulin glargine, glimepiride, liraglutide, or sitagliptin to metformin, with the medication combination continued until the HbA1c was greater than 7.5%; thereafter, insulin was added to maintain glycemic control.Main Outcomes and MeasuresChronic eGFR slope (change in eGFR between year 1 and trial end) and a composite kidney disease progression outcome (albuminuria, dialysis, transplant, or death due to kidney disease). Secondary outcomes included incident eGFR less than 60 mL/min/1.73 m2, 40% decrease in eGFR to less than 60 mL/min/1.73 m2, doubling of urine albumin-to-creatinine ratio (UACR) to 30 mg/g or greater, and progression of Kidney Disease Improving Global Outcomes stage. Analyses were intention-to-treat.ResultsOf the 5047 participants, 3210 (63.6%) were men. Baseline characteristics were mean (SD) age 57.2 (10.0) years; HbA1c 7.5% (0.5%); diabetes duration, 4.2 (2.7) years; body mass index, 34.3 (6.8); blood pressure 128.3/77.3 (14.7/9.9) mm Hg; eGFR 94.9 (16.8) mL/min/1.73 m2; and median UACR, 6.4 (IQR 3.1-16.9) mg/g; 2933 (58.1%) were treated with renin-angiotensin-aldosterone inhibitors. Mean chronic eGFR slope was −2.03 (95% CI, −2.20 to −1.86) mL/min/1.73 m2 per year for patients receiving sitagliptin; glimepiride, −1.92 (95% CI, −2.08 to −1.75) mL/min/1.73 m2 per year; liraglutide, −2.08 (95% CI, −2.26 to −1.90) mL/min/1.73 m2 per year; and insulin glargine, −2.02 (95% CI, −2.19 to −1.84) mL/min/1.73 m2 per year (P = .61). Mean composite kidney disease progression occurred in 135 (10.6%) patients receiving sitagliptin; glimepiride, 155 (12.4%); liraglutide, 152 (12.0%); and insulin glargine, 150 (11.9%) (P = .56). Most of the composite outcome was attributable to albuminuria progression (98.4%). There were no significant differences by treatment assignment in secondary outcomes. There were no adverse kidney events attributable to medication assignment.Conclusions and RelevanceIn this randomized clinical trial, among people with T2D and predominantly free of kidney disease at baseline, no significant differences in kidney outcomes were observed during 5 years of follow-up when a dipeptidyl peptidase 4 inhibitor, sulfonylurea, glucagonlike peptide 1 receptor agonist, or basal insulin was added to metformin for glycemic control.Trial RegistrationClinicalTrials.gov Identifier: NCT01794143
