There were decreases in total cholesterol (−21%), LDL‐C (−32%), non‐HDL‐C (−31%) and apoB (−26%) in the atorvastatin group versus placebo (p < 0.001). Lipoprotein subparticles (LDL‐large 1 and 2A, IDL‐large and small, VLDL‐ medium and small) decreased with statins (p < 0.03 all). Insulin sensitivity scores remained constant in both groups and correlated inversely with apoB (r = −0.312 p = 0.039) and small LDL 3A (r = −0.404 p = 0.007). One subject had asymptomatic elevation of creatinine kinase which normalized after atorvastatin discontinuation.</p> </sec> <sec id="pedi12245-sec-0006" sec-type="section"> <title>Conclusions</title> <p id="pedi12245-para-0006">Atorvastatin lowered LDL‐C, apoB, and atherogenic lipoprotein subparticles in children with T1D and elevated LDL‐C without worsening insulin resistance. The drug was well tolerated and safe. Long‐term studies would provide better insight on the impact of these interventions in the development of cardiovascular disease in children with diabetes.</p> </sec> </abstract>
