Background

There is limited information regarding the optimal third-line therapy for managing type 2 diabetes mellitus (T2DM) that is inadequately controlled using dual combination therapy. This study assessed the efficacy and safety of pioglitazone or glimepiride when added to metformin plus alogliptin treatment for T2DM.

Methods

This multicenter, randomized, active-controlled trial (ClinicalTrials.gov: NCT02426294) recruited 135 Korean patients with T2DM that was inadequately controlled using metformin plus alogliptin. The patients were then randomized to also receive pioglitazone (15 mg/day) or glimepiride (2 mg/day) for a 26-week period, with dose titration was permitted based on the investigator's judgement.

Results

Glycosylated hemoglobin levels exhibited similar significant decreases in both groups during the treatment period (pioglitazone: −0.81%, P<0.001; glimepiride: −1.05%, P<0.001). However, the pioglitazone-treated group exhibited significantly higher high density lipoprotein cholesterol levels (P<0.001) and significantly lower homeostatic model assessment of insulin resistance values (P<0.001). Relative to pioglitazone, adding glimepiride to metformin plus alogliptin markedly increased the risk of hypoglycemia (pioglitazone: 1/69 cases [1.45%], glimepiride: 14/66 cases [21.21%]; P<0.001).

Conclusion

Among patients with T2DM inadequately controlled using metformin plus alogliptin, the addition of pioglitazone provided comparable glycemic control and various benefits (improvements in lipid profiles, insulin resistance, and hypoglycemia risk) relative to the addition of glimepiride.

Background

Metformin, sulfonylurea, and dietary fiber are known to affect gut microbiota in patients with type 2 diabetes mellitus (T2DM). This open and single-arm pilot trial investigated the effects of the additional use of fiber on glycemic parameters, insulin, incretins, and microbiota in patients with T2DM who had been treated with metformin and sulfonylurea.

Methods

Participants took fiber for 4 weeks and stopped for the next 4 weeks. Glycemic parameters, insulin, incretins during mixed-meal tolerance test (MMTT), lipopolysaccharide (LPS) level, and fecal microbiota were analyzed at weeks 0, 4, and 8. The first tertile of difference in glucose area under the curve during MMTT between weeks 0 and 4 was defined as ‘responders’ and the third as ‘nonresponders,’ respectively.

Results

In all 10 participants, the peak incretin levels during MMTT were higher and LPS were lower at week 4 as compared with at baseline. While the insulin sensitivity of the ‘responders’ increased at week 4, that of the ‘nonresponders’ showed opposite results. However, the results were not statistically significant. In all participants, metabolically unfavorable microbiota decreased at week 4 and were restored at week 8. At baseline, metabolically hostile bacteria were more abundant in the ‘nonresponders.’ In ‘responders,’ Roseburia intestinalis increased at week 4.

Conclusion

While dietary fiber did not induce additional changes in glycemic parameters, it showed a trend of improvement in insulin sensitivity in ‘responders.’ Even if patients are already receiving diabetes treatment, the additional administration of fiber can lead to additional benefits in the treatment of diabetes.

Background

There were a limited number of studies about β-cell function after insulin initiation in patients exposed to long durations of sulfonylurea treatment. In this study, we aimed to evaluate the recovery of β-cell function and the efficacy of concurrent sulfonylurea use after the start of long-acting insulin.

Methods

In this randomized controlled study, patients with type 2 diabetes mellitus (T2DM), receiving sulfonylurea for at least 2 years with glycosylated hemoglobin (HbA1c) >7%, were randomly assigned to two groups: sulfonylurea maintenance (SM) and sulfonylurea reduction (SR). Following a 75-g oral glucose tolerance test (OGTT), we administered long-acting basal insulin to the two groups. After a 6-month follow-up, we repeated the OGTT.

Results

Among 69 enrolled patients, 57 completed the study and were analyzed: 31 in the SM and 26 in the SR group. At baseline, there was no significant difference except for the longer duration of diabetes and lower triglycerides in the SR group. After 6 months, the HbA1c was similarly reduced in both groups, but there was little difference in the insulin dose. In addition, insulin secretion during OGTT was significantly increased by 20% to 30% in both groups. A significant weight gain was observed in the SM group only. The insulinogenic index was more significantly improved in the SR group.

Conclusion

Long-acting basal insulin replacement could improve the glycemic status and restore β-cell function in the T2DM patients undergoing sulfonylurea-based treatment, irrespective of the sulfonylurea dose reduction. The dose reduction of the concurrent sulfonylurea might be beneficial with regard to weight grain.

Background

Dipeptidyl peptidase-4 (DPP-4) inhibitor add-on therapy is a new option for patients with inadequately controlled type 2 diabetes who are taking combined metformin and sulfonylurea (SU). We evaluated the efficacy and safety of this triple therapy and the characteristics of rapid responders and hypoglycemia-prone patients.

Methods

We included 807 patients with type 2 diabetes who were prescribed a newly added DPP-4 inhibitor to ongoing metformin and SU in 2009 to 2011. Glycemia and other metabolic parameters at baseline, 12, 24, and 52 weeks, as well as episodes of hypoglycemia were analyzed. Rapid responders were defined as patients with ≥25% reduction in glycosylated hemoglobin (HbA1c) within 12 weeks.

Results

At baseline, while on the submaximal metformin and SU combination, the mean HbA1c level was 8.4%. Twelve weeks after initiation of DPP-4 inhibitor add-on, 269 patients (34.4%) achieved an HbA1c level ≤7%. Sixty-six patients (8.2%, 47 men) were rapid responders. The duration of diabetes was shorter in rapid responders, and their baseline fasting plasma glucose (FPG), HbA1c, C-peptide, and homeostasis model assessment of insulin resistance were significantly higher. Patients who experienced hypoglycemia after taking DPP-4 inhibitor add-on were more likely to be female, to have a lower body weight and lower triglyceride and FPG levels, and to have higher homeostasis model assessment of β-cells.

Conclusion

An oral hypoglycemic triple agent combination including a DPP-4 inhibitor was effective in patients with uncontrolled diabetes. Proactive dose reduction of SU should be considered when a DPP-4 inhibitor is added for rapid responders and hypoglycemia-prone patients.

Background

Sulfonylurea primarily stimulates insulin secretion by binding to its receptor on the pancreatic β-cells. Recent studies have suggested that sulfonylureas induce insulin sensitivity through peroxisome proliferator-activated receptor γ (PPARγ), one of the nuclear receptors. In this study, we investigated the effects of sulfonylurea on PPARγ transcriptional activity and on the glucose uptake via PPARγ.

Methods

Transcription reporter assays using Cos7 cells were performed to determine if specific sulfonylureas stimulate PPARγ transactivation. Glimepiride, gliquidone, and glipizide (1 to 500 µM) were used as treatment, and rosiglitazone at 1 and 10 µM was used as a control. The effects of sulfonylurea and rosiglitazone treatments on the transcriptional activity of endogenous PPARγ were observed. In addition, 3T3-L1 adipocytes were treated with rosiglitazone (10 µM), glimepiride (100 µM) or both to verify the effect of glimepiride on rosiglitazone-induced glucose uptake.

Results

Sulfonylureas, including glimepiride, gliquidone and glipizide, increased PPARγ transcriptional activity, gliquidone being the most potent PPARγ agonist. However, no additive effects were observed in the presence of rosiglitazone. When rosiglitazone was co-treated with glimepiride, PPARγ transcriptional activity and glucose uptake were reduced compared to those after treatment with rosiglitazone alone. This competitive effect of glimepiride was observed only at high concentrations that are not achieved with clinical doses.

Conclusion

Sulfonylureas like glimepiride, gliquidone and glipizide increased the transcriptional activity of PPARγ. Also, glimepiride was able to reduce the effect of rosiglitazone on PPARγ agonistic activity and glucose uptake. However, the competitive effect does not seem to occur at clinically feasible concentrations.

Abstract PDF: BACKGROUND
The ATP-sensitive potassium (KATP) channel comprises an inwardly- rectifying K+ channel (Kir) and a sulfonylurea receptor(SUR). This study investigated the mechanism of different ATP sensitivity between skeletal-(Kir6.2/SUR2A) and smooth muscle- (Kir6.2/SUR2B) type KATP channels. METHODS: Messenger RNAs encoding mouse Kir6.2, and rat SUR2A or 2B were co-injected into Xenopus Laevis oocytes to express each type of KATP channel. Using the inside-out patch clamp technique, the channel currents for MgATP sensitivity were measured and analyzed. RESULTS: By addition of 100 microM of MgATP, the current initially decreased and then slowly increased in Kir6.2/SUR2A. This gradual, ATP sensitivity decrease during prolonged MgATP application was totally blocked by LY 294002, a pho- sphatidylinositol-3 and -4 kinase inhibitor. In contrast, a rather rapid sensitivity decrease after initial inhibition was observed in Kir6.2/SUR2B by 100 microM of ATP, which was not blocked by LY 294002. This channel activation was Mg2+- dependent, suggesting that ATP hydrolysis is critical. CONCLUSION: This result supports the idea that the ability of MgATP to stimulate Kir6.2/SUR2B channels reflects a faster rate of ATP hydrolysis at NBD2 of SUR2B.

Abstract PDF: BACKGROUND
Acarbose-an aglucosidase inhibitor-is known to have a glucose lowering effect by delaying the digestion of complex carbohydrates in the small intestine. Acarbose especially prevents the abnormally high increment of postprandial blood glucose, reduces postprandial hyperinsulinemia and probably, alleviates insulin resistance. The aim of this study is to evaluate the glucose lowering effect of acarbose as an adjunt with a sulfonylurea in the treatment of NIDDM patients who have been poorly controlled with the use of sulfonylurea alone. METHODS: Forty NIDDM patients, who were poorly controlled with sulfonylurea alone, were randomly selected frorn outpatient diabetic clinic for study. For 16 weeks, they recieved either acarbose or placebo in additian to sulfonylurea under double blind method. RESULTS: 1) The metabohc parameters measured before initiation of either treatment regimen were similiar. 2) The HbAlc in placebo group increased from 8.9% to 9.0%. In contrast, in the acarbose group, HbAlc value decreased from 9.3% to 8.1%(p<0.05). 3) Mean fasting plasma glucose and 1-h postprandial glucose levels were reduced significantly in the acarbose group(p<0.001), especially in I-h postpandial glucose level in comparison with placebo group(p <0.0001). 4) Mean fasting, 1-h postprandial insulin levels decreased with time in the acarbose group in comparison with placebo group, but the decrease was not statistically significant. 5) Lipid profiles did not change during 16weeks of treatment period. 6) Adverse effects were observed in 3 patients on acarbose and 2 patients on placebo. CONCLUSION: Acarbose can be used as an effective adjuvant therapy to sulfonylurea in NIDDM patients who are poorly controlled with sulfonylurea alone.

Abstract PDF: BACKGROUND
We performed this study to investigate the effect of metformin on glycemia, insulin secretion and body weight in patients with non-insulin-dependent diabetes melltus(NIDDM) who could not aehieve satisfactory glycemic control by sulfonylurea or diet therapy. METHODS: A total of 167 patients with NIDDM were included in this study. At baseline the patients underwent anthropometry and a 75g oral glucose tolerance test. Jn addition, levels of hemoglobin Alc (HbAlc), setum lipids, fasting and postprandial 2hr glucose were measured. Metformin was given in an initial dose of 500mg twice daily and increased by 500mg every month as long as the fasting blood sugar(FBS) concentration exceeded 7.8mmol/L and the side effects were tolerable. After 3 rnonths of metformin therapy we defined a responder as a patient who experienced a FBS of under 7.8 mmol/L or a HbAlc of under 7%. Patients who failed to respond to metformin monotherapy were excluded in the study. Anthrapometric changes and results of a 75 g oral glucose tolerance test were reevaluated in the responder group after 6 months of metformin treatment. RESULTS: I) The overall response rate to metformin mono-therapy was 55.6%(79/142) in the study population. 2) There were significant changes in body weight (64.4+/-8.2 vs 62.9+/-8.4 kg, p(0.01) and body mass index(25.3+/-2.3 vs 24.6+/-2.3kg/m, p<0.01) during metformin treatment. 3) There were significant decreases in the fasting, postprandial 2hr serum glucose(10.1+/-2.8 vs 7.9+1.6, 15,2+/-5.0 vs 12.2+/-3.9 mmol/L, p 0.01) and HbAlc levels(8.4+/-1.7 vs 6.5+/-0.9%, p<0.05) after 6 months of metformin treatment. 4) There were significant decreases in the levels of AUC[g](59.2+/-15.5 vs 49.4+/-9.4mmol L-1. Min-1, p =C0.01) without changes of AUC[I] and AUC[I]/ AUC[g] ratio (558.0+486.0 vs 536.4+374.4 pmol.L-1. Min-1, p=0.71, 11.7+/-13.0 vs 11.8+/-10.0, p=0.89). 5) The incidence of side effects was 25% in the study population, but most of them were mild and fade away with continuous use of metformin, CONCLUSION: Metforrnin monotherapy improved glycemic control in NlDDM patients who failed to respond to diet or sulfonylurea therapy and may be a useful hypoglycemic agent for the treatment of NIBDM.
