The Effect of Triglyceride Concentration on Attainment of Lipid Targets in Patients with Diabetes

To evaluate the effects of triglyceride (TG) and glycated hemoglobin (A1C) concentrations in the percentage of patients with diabetes who are within target (WT) for low-density lipoprotein-cholesterol (LDL-C), non-high-density lipoprotein-cholesterol (non-HDL-C) and apolipoprotein B (ApoB), as defin...

Description
Summary:To evaluate the effects of triglyceride (TG) and glycated hemoglobin (A1C) concentrations in the percentage of patients with diabetes who are within target (WT) for low-density lipoprotein-cholesterol (LDL-C), non-high-density lipoprotein-cholesterol (non-HDL-C) and apolipoprotein B (ApoB), as defined by the Canadian Lipid Guidelines, in a cohort of outpatients presenting at a 350-bed community hospital. Laboratory samples from 1919 patients, 18 years or older, who had A1C levels of 6.5% or above were used. Fasting lipid profiles were retrieved, and ApoB was measured. We found no significant difference in the percentage of those WT for LDL-C as TG increased from normal to intermediate and high levels. For non-HDL-C, we saw a substantial decrease in the percentage of patients WT as TG levels increased from normal (61%) to intermediate (30.4%) and high levels (14.0%). ApoB showed a similar pattern to non-HDL-C: decreasing from normal (68.8%) to intermediate (40.7%) and high levels (21.0%). No significant difference was seen in the percentage of patients WT for the 3 lipid parameters studied with the increase in A1C levels. As TG increases, we saw discordance in the percentage of patients WT for LDL-C in relation to non-HDL-C and ApoB. Alternative targets to LDL-C should preferentially be used when the TG concentration is elevated. Évaluer les effets des concentrations de triglycérides (TG) et d'hémoglobine glyquée (A1C) dans le pourcentage des patients diabétiques qui sont à l'intérieur des cibles (IC) pour le cholestérol des lipoprotéines de faible densité (cholestérol LDL), le cholestérol non–HDL et l'apolipoprotéine B (ApoB), selon les lignes directrices canadiennes sur les lipides, chez une cohorte de patients en consultation externe qui se présentent dans un hôpital communautaire de 350 lits. Des échantillons sanguins de 1919 patients de 18 ans et plus qui avaient des concentrations d'A1C de 6,5 % ou plus ont été utilisés. Les profils lipidiques à jeun ont été récupérés et l'ApoB a été mesurée. Nous n'avons observé aucune différence significative dans le pourcentage de ceux IC quant au cholestérol LDL alors que les TG passaient de concentrations normales à des concentrations intermédiaires et élevées. Quant au cholestérol non–HDL, nous avons constaté une diminution substantielle dans le pourcentage de patients IC alors que les concentrations de TG passaient de concentrations normales (61 %) à des concentrations intermédiaires (30,4 %) et élevées (14,0 %
