In addition, it should be noted that we analyzed samples from 35 of the 43 patients who completed the study because serum samples were not obtained from eight patients. Our previous

study using the same sample demonstrated that glucose fluctuations in 43 type 2 diabetic Japanese patients were reduced by switching from acarbose or voglibose to miglitol for 3 months. In this study, we obtained the same result in 35 patients. Thus, missing data from the eight patients would this website be less likely to affect the results of this study. It should be noted that our study is relatively small in scale. It has been reported that an increase of the postprandial

incremental area under the curve of blood glucose in a single oral meal test in eight type 2 diabetic patients was reduced by miglitol treatment at doses of 50, 75, 100, and 200 mg [29]. An RCT of 36 type 2 diabetic patients found that postprandial blood glucose levels were reduced by ~50 % in patients treated with miglitol compared with those treated with placebo [30]. A double-blind, crossover design in 15 type 2 diabetic patients found that treatment with miglitol (300 mg/day) effectively reduced postprandial blood glucose levels over 8 weeks [31]. In addition, a previous selleck chemicals llc study reported that treatment with miglitol in 24 viscerally obese subjects reduced glucose fluctuations and circulating IL-6 concentrations versus acarbose treatment [17]. In addition, our previous study reported that the switch of α-GI from acarbose or voglibose to miglitol in 43 type 2 diabetic patients reduced glucose fluctuations and expression of inflammatory

cytokine genes, such as IL-1β and TNF-α, in peripheral leukocytes and the circulating protein concentrations of TNF-α [19]. From these studies, we considered that our sample of 35 type 2 diabetic Japanese patients is comparable; however, a large-scale RCT is needed to examine whether miglitol reduces glucose fluctuations and circulating Depsipeptide order concentrations of CVD risk factors in type 2 diabetic patients compared with other α-GIs. We assessed glucose fluctuations by SMBG. Recent studies have suggested that blood glucose profiles monitored by SMBG are not always correlated with continuous glucose monitoring (CGM), particularly given that measurement of blood glucose concentrations by SMBG often omit hypoglycemic events entirely [32, 33]. A study of ten type 2 diabetic patients hospitalized for 4 days found that glucose fluctuations, which were monitored by CGM, in a standard meal loading were reduced effectively by treatment with miglitol (50 mg) compared with acarbose (100 mg) [34].
