Fifteen children with spinal muscular atrophy type 1 received gene-replacement therapy with a single dose of adeno-associated virus containing SMN. In marked contrast to well-characterized historical cohorts, all the patients survived at least 20 months and most reached motor milestones.

To assess the effect of the bile acid sequestrant colesevelam hydrochloride in patients with hypercholesterolemia and prediabetes. In this 16-week, randomized, double-blind study, adults with untreated prediabetes (2-hour postoral glucose tolerance test [OGTT] glucose > or =140 to 199 mg/dL, fasting plasma glucose [FPG] > or =110 to 125 mg/dL, or both), low-density lipoprotein cholesterol (LDL-C) > or =100 mg/dL, and triglycerides <500 mg/dL were randomly assigned to receive colesevelam (3.75 g/d) or placebo. The primary end point was percent change in LDL-C from baseline to week 16 with last observation carried forward. Secondary end points included change in FPG, hemoglobin A1c (A1C), and 2-hour post-OGTT glucose level from baseline to week 16 and attainment of LDL-C and FPG targets. In total, 216 patients were randomized (colesevelam, 108; placebo, 108). In comparison with placebo, colesevelam significantly reduced LDL-C (mean treatment difference, -15.6%), non-high-density lipoprotein cholesterol (-9.1%), total cholesterol (-7.2%), apolipoprotein B (-8.1%) (P<.001 for all the foregoing), FPG (median, -2.0 mg/dL; P = .02), and A1C (mean, -0.10%; P = .02). Colesevelam did not significantly change 2-hour post-OGTT glucose (-1.9 mg/dL; P = .75) or high-density lipoprotein cholesterol (-0.5%; P = .80). In addition, colesevelam significantly increased triglyceride levels relative to placebo (median, 14.3%; P<.001). The proportion of patients achieving target levels with colesevelam versus placebo, respectively, was as follows: LDL-C <100 mg/dL (29% versus 11%; P<.001), A1C <6.0% (37% versus 25%; P = .05), FPG <110 mg/dL (48% versus 56%; P = .97), and normalization of glucose (FPG <100 mg/dL [40% versus 23%; P = .06]). Colesevelam had a weight-neutral effect and was well tolerated. Colesevelam is an option for managing the lipid profile and normalizing glucose levels in patients with hypercholesterolemia and prediabetes. Further study is warranted to determine whether colesevelam slows or prevents progression of prediabetes to type 2 diabetes.

To evaluate the efficacy and safety of initial combination therapy with metformin plus colesevelam in patients with early type 2 diabetes. In this 16-week, randomized, double-blind, placebo-controlled study, adults with type 2 diabetes (hemoglobin A1c [A1C] values of 6.5% to 10.0%) and hypercholesterolemia (low-density lipoprotein cholesterol [LDL-C] levels > or =100 mg/dL) were randomly assigned (1:1) to colesevelam (3.75 g/d) or placebo in combination with open-label metformin (850 mg/d; uptitrated at week 2 to 1,700 mg/d). The primary efficacy evaluation was change in A1C from baseline to study end (week 16 with last observation carried forward). In total, 286 patients were randomized: metformin/colesevelam (n = 145) or metformin/placebo (n = 141). Mean A1C was reduced by 1.1% with metformin/colesevelam (from 7.8% at baseline to 6.6% at study end) and by 0.8% with metformin/placebo (from 7.5% to 6.7%), resulting in a treatment difference of -0.3% at study end (P = .0035). In addition, metformin/colesevelam significantly reduced LDL-C (-16.3%), total cholesterol (-6.1%), non-high-density lipoprotein cholesterol (-8.3%), apolipoprotein B (-8.0%), and high-sensitivity C-reactive protein (-17%) and increased apolipoprotein A-I (+4.4%) and triglycerides (+18.6%) versus metformin/placebo (P<.01 for all). The proportions of patients who achieved recommended goals with metformin/colesevelam versus metformin/placebo, respectively, were as follows: A1C <7.0% (67% versus 56% [P = .0092]), LDL-C <100 mg/dL (48% versus 18% [P<.0001]), and composite A1C <7.0% + LDL-C <100 mg/dL (40% versus 12% [P<.0001]). Safety and tolerability were similar between the treatment groups. Metformin plus colesevelam may be a valid option for initial therapy to achieve glycemic and lipid goals safely in early type 2 diabetes.

The Affordable Care Act (ACA) was premised on the theory that expanded access to health insurance would facilitate greater access to health services, thereby leading to earlier detection and treatment of disease for a larger number of people. While the ACA has been the subject of five years of spirited dialogue, new evidence is emerging that suggests expanded access to care under the ACA may be having an impact on early identification of diabetes. It is the author's fervent hope that the combined efforts of researchers, physicians and policymakers will have a measureable difference in the rate of newly diagnosed diabetes for the next generation.
