OBJECTIVE: To assess the design and the Mainland China subgroup baseline characteristics of the study to evaluate the efficacy and safety of alogliptin versus placebo in subjects with type 2 diabetes (T2DM) as monotherapy, add-on to metformin or add-on to pioglitazone. METHODS: This was a multi-center, randomized, double-blind, placebo-controlled, 16-week study comparing alogliptin (ALO, 25 mg, 1/d) versus placebo (PLA) as monotherapy (A), add-on to metformin (B) or add-on to pioglitazone ± metformin (C). The T2DM subjects with glycosylated hemoglobin A1c(HbA1c) between 7% and 10% and aged between 18 years and 75 years were enrolled and randomized to the alogliptin group and the placebo group in 1: 1 ratio with 16 weeks treatment. All patients were followed up every 4 weeks. The safety endpoints consisted of the incidence of hypoglycemia and other adverse events. RESULTS: A total of 491 patients were enrolled in the Mainland China subgroup of the study (181 in group A, 186 in group B and 124 in group C). In each treatment group, the baseline characteristics including age, gender, body mass index, diabetes duration, HbA1c, fasting plasma glucose, body weight, daily dosage of metformin and daily dosage of pioglitazone were all well balanced. CONCLUSION: The demographic data, medical history, glycemic profile and treatment regimen at baseline in Mainland China subgroup are well balanced. The result of this study will provide the clinical evidence for the use of alogliptin in Chinese T2DM patients.

OBJECTIVE: To evaluate the relationship between 25-hydroxy vitamin D [25(OH)D] and carotid artery intimal medial thickness (IMT) in type 2 diabetic (T2DM) patients. METHODS: Serum 25(OH)D and carotid IMT were measured in 300 T2DM patients. Patients were divided into four quartile groups according to the serum 25(OH)D levels (Q1: < 26.17 nmol/L, 74 cases; Q2: 26.17 - 32.75 nmol/L, 76 cases; Q3: 32.75 - 42.93 nmol/L, 78 cases; Q4 > 42.93 nmol/L, 72 cases). RESULTS: Carotid IMT, carotid artery plaque prevalence, duration of diabetes, HbA1c, CRP and PTH were significantly higher in subjects with low 25(OH)D compared subjects with high 25(OH)D (P < 0.05). Carotid artery IMT in Q1 and Q2 groups were significantly higher than that in Q4 group (1.03 ± 0.21 vs. 0.90 ± 0.20, 1.01 ± 0.26 vs. 0.90 ± 0.20, P < 0.05), was similar among Q1 and Q2 and Q3 groups. Prevalence of carotid atherosclerotic plaque in Q1 group (50.0%) was also significantly higher than in Q3 (29.5%, P < 0.05) and Q4 (16.7%, P < 0.05). Similarly, 25(OH)D concentration was significantly lower in patients with carotid plaque compared patients without carotid plaque [(28.31 ± 4.91) nmol/L vs. (36.31 ± 4.31) nmol/L, P < 0.01]. Pearson correlation analysis showed that carotid IMT was positively correlated with age, smoking, BMI, HbA1c, CRP, LDL-C, PTH/25(OH)D ratio (P < 0.05), and was negatively correlated with 25 (OH) D (r = -0.51, P < 0.01). Multivariate regression analysis showed that 25(OH)D concentration was an independent predictor of carotid IMT in this cohort (ß = -0.39, P < 0.01). CONCLUSION: Serum 25(OH)D concentration is negatively correlated with carotid IMT and low 25 (OH) D level is a risk factor for preclinical atherosclerosis in T2DM patients.
