New approach for detection of LDL-hypercholesterolemia in the pediatric population: The Fr1dolin-Trial in Lower Saxony, Germany.

BACKGROUND AND AIMS: Lipid disorders are often detected very late, particularly in affected young children. We evaluated the feasibility of a screening for LDL-hypercholesterolemia (highLDL) among toddlers and preschoolers. METHODS: Population-based screening has been offered to all children (2-6 years) living in the State of Lower Saxony, Germany, with capillary blood sampling for detection of elevated LDL-cholesterol (LDL-C ≥ 135 mg/dL). Positive results were confirmed by a second measurement. Follow-up in specialized centers, including disease specific counselling and extended diagnostics, as well as evaluation of psychological distress of the parents, is carried out longitudinally. RESULTS: Up to March 2018, 5656 children have participated in the screening program. 5069/5656 children have completed the screening for highLDL (52.0% boys; median age: 4.0 years [Interquartile range, IQR 3.0-5.1]; mother age: 35 years [IQR 31-38]; father's age: 37 years; [IQR 33-42]). HighLDL was identified in 112 children (2.2%; 40.2% boys; LDL-C 157.6 ±â€¯29.5 mg/dL, mean ±â€¯SD). In the total cohort, parents stated in 40.9% of the cases a positive family history for hyperlipidemia and in 29.9% a premature cardiovascular event. Children with highLDL had more often both risk factors in their family history; however, in 37% of them none of these factors were reported. CONCLUSIONS: The first results of the screening program showed its feasibility and revealed high prevalence of highLDL in the general population. Furthermore, a large proportion of families of affected children were not aware about their lipid disorders.

Effects of dapagliflozin on insulin-requirement, glucose excretion and ß-hydroxybutyrate levels are not related to baseline HbA1c in youth with type 1 diabetes.

Youth with type 1 diabetes (T1D) infrequently achieve HbA1c targets. Therefore, this placebo-controlled, randomized, crossover study was set up to assess the safety, effect and pharmacokinetics of a single dose of 10 mg dapagliflozin (DAPA) as add-on to insulin in relationship to HbA1c in youth. A total of 33 youths (14 males, median age 16 years, diabetes duration 8 years) were included and stratified into 3 baseline HbA1c categories (<7.5%, 7.5%-9.0% or >9.0; n = 11 each). During the study period of 24 hours, intravenous insulin administration and glucose-infusion kept blood glucose levels at 160 to 220 mg/dL. DAPA reduced mean insulin dose by 13.6% ( P < .0001 by ANOVA) and increased urinary glucose excretion by 610% (143.4 vs 22.4 g/24 h; P < .0001), both irrespective of baseline HbA1c. Six independent episodes in 6 patients with plasma ß-hydroxybutyrate levels between ≥0.6 and <1.0 mmol/L were observed after liquid meal challenges, 5 episodes in the DAPA group and 1 in the placebo group. This study provides a proof-of-concept, irrespective of preexisting HbA1c levels, for adjunct SGLT2-inhibitor therapy in the paediatric age group by lowering insulin dose and increasing glucose excretion.
