BACKGROUND: Metabolic syndrome (MetSyn) is associated with a marked increase in the risk of cardiovascular disease, especially in patients with type 2 diabetes mellitus (DM). AIM: To investigate the effect of orlistat plus hypocaloric diet (HCD) vs HCD alone on the cardiovascular risk profile in patients with both MetSyn (National Cholesterol Educational Program--NCEP--Adult Treatment Panel III definition) and type 2 DM. METHODS: This was a prospective, multicentre, open-label, randomized, controlled study. One hundred and twenty-six patients, free of cardiovascular disease at baseline, were included in the final analysis. Ninety-four (73%) patients were treated with orlistat (360 mg/day) and HCD for a 6-month period, while 34 (27%) were on HCD alone. Analysis of covariance was used to assess differences between the treatment groups over time. MAIN OUTCOME MEASURES: Components of the MetSyn criteria assessed were: waist circumference; systolic and diastolic blood pressure; fasting glucose, triglycerides; high-density lipoprotein cholesterol (HDL-C) plus body mass index; glycosylated haemoglobin (HbA1C); homeostasis model for assessment of insulin resistance (HOMA) index; and total and low-density lipoprotein cholesterol (LDL-C). RESULTS: By protocol, all patients had MetSyn at baseline. After a 6 month treatment period there were significant differences between the orlistat plus HCD vs the HCD-alone groups in body weight (p = 0.0001), waist circumference (p < 0.0001), fasting glucose (p < 0.0001), HbA(1C) (p < 0.0001), systolic blood pressure (p = 0.024), total cholesterol (p < 0.0001), LDL-C (p = 0.034), and HOMA index (p = 0.022), while there were no significant differences in triglycerides and HDL-C. Orlistat was well tolerated. By the end of the study, 65% of the patients on orlistat plus HCD were still meeting the MetSyn criteria and 41% had four to five MetSyn components vs 91% (p < 0.0001) and 53% (p = 0.017), respectively, of those on HCD alone. CONCLUSIONS:Orlistat plus HCD favourably modified several cardiovascular risk factors in patients with both MetSyn and type 2 DM. These effects might partly offset the excess cardiovascular risk and improve outcome in this patient population.
