Lipoprotein risk factors for cardiovascular disease in patients with type 2 diabetes mellitus treated with oral antihyperglycaemic agents
Abstract
AIMS: To compare lipoprotein risk factors for cardiovascular disease (CVD) in patients with type 2 diabetes mellitus (DM) treated with a sulphonylurea (SU) compound only, metformin (MET) only, or combined SU + MET.
METHODS: The study population consisted of 62 patients with type 2 DM, whose antihyperglycaemic treatment program had been stable for at least 3 months, divided into three groups: 26 patients in the SU group, 17 patients in the MET group and 19 patients in the SU + MET group. None of the patients were taking lipid-lowering drugs. Fasting venous blood samples were taken to measure concentrations of glucose, total cholesterol, triglycerides (TG), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C) and remnant lipoprotein-cholesterol (RLP-C) as well as for determination of LDL particle diameter.
RESULTS: The three groups were similar in terms of age, gender, body mass index and fasting plasma glucose concentrations. Total cholesterol concentrations were significantly lower (p < 0.05 for trend) in those treated with SU + MET as compared with the other two groups. However, there were no significant differences between the three groups in their plasma concentrations of TG, LDL-C, HDL-C or RLP-C; furthermore, the proportion of individuals within each treatment group with small LDL particle diameter was also not different.
CONCLUSIONS: The lipoprotein profile of patients with type 2 DM, matched for level of fasting hyperglycaemia, was…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 62 participants or records.
