Background

Only few studies have shown the efficacy and safety of glucose-control strategies using the quadruple drug combination. Therefore, the aim of the present study was to investigate the usefulness of the quadruple combination therapy with oral hypoglycemic agents (OHAs) in patients with uncontrolled type 2 diabetes mellitus (T2DM).

Methods

From March 2014 to December 2018, data of patients with T2DM, who were treated with quadruple hypoglycemic medications for over 12 months in 11 hospitals in South Korea, were reviewed retrospectively. We compared glycosylated hemoglobin (HbA1c) levels before and 12 months after quadruple treatment with OHAs. The safety, maintenance rate, and therapeutic patterns after failure of the quadruple therapy were also evaluated.

Results

In total, 357 patients were enrolled for quadruple OHA therapy, and the baseline HbA1c level was 9.0%±1.3% (74.9±14.1 mmol/mol). After 12 months, 270 patients (75.6%) adhered to the quadruple therapy and HbA1c was significantly reduced from 8.9%±1.2% to 7.8%±1.3% (mean change, −1.1%±1.2%; P<0.001). The number of patients with HbA1c <7% increased significantly from 5 to 68 (P<0.005). In addition, lipid profiles and liver enzyme levels were also improved whereas no changes in body weight. There was no significant safety issue in patients treated with quadruple OHA therapy.

Conclusion

This study shows the therapeutic efficacy of the quadruple OHA regimen T2DM and demonstrates that it can be an option for the management of T2DM patients who cannot use insulin or reject injectable therapy.

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

Thyroid disease and metabolic syndrome are both associated with cardiovascular disease. The aim of this study was to investigate the correlation between thyroid hormones and obesity sub-phenotypes using nationwide data from Korea, a country known to be iodine replete.

Methods

This study was based on data obtained from the sixth Korea National Health and Nutrition Examination Survey, administered from 2013 to 2015. A total of 13,873 participants aged ≥19 years were included, and classified into four groups: metabolically healthy non-obesity (MHNO), metabolically healthy obesity (MHO), metabolically unhealthy non-obesity (MUNO), and metabolically unhealthy obesity (MUO) by body fat on the basis of body mass index and metabolic health.

Results

At baseline, serum free thyroxine (fT4) values were significantly higher in the MHNO phenotype (MHNO, 1.27±0.01 ng/dL; MHO, 1.25±0.01 ng/dL; MUNO, 1.24±0.01 ng/dL; MUO, 1.24±0.01 ng/dL, P<0.001) in total study population. However, this significant association no longer remained after adjustment for age, urine iodine concentration, and smoking (P=0.085). After adjustment for confounders, statistically significant association was observed between lower thyroid stimulating hormone (TSH) and MHNO phenotype (P=0.044). In men participants (not women), higher fT4 values were significantly associated with MHNO phenotype (P<0.001). However, no significant association was observed between thyroid function (TSH or fT4) and obesity phenotypes in groups classified by age (cutoff age of 55 years).

Conclusion

Although there was a difference by age and sex, we found that the decrease of TSH and the increase of fT4 values were associated with MHNO.

Abstract PDF: BACKGROUND
Fatty acid binding protein (FABP), putative mammalian fatty acid transporter, plays a role in fatty acid transport, the modulation of cellular signal transduction pathways and the protection against detergent like effects of fatty acids. FABP found in liver, adipose tissue, heart, skeletal muscle and FABP in skeletal muscle accounts for 2% of total protein mass. FABP expression has shown to be up-regulated by PPAR in liver and adipocyte. Adipocyte and liver FABP genes have a functional PPRE (PPAR responsive element) in their promoter region. This evidence led us to investigate for a possible the regulation of mFABP expression by PPAR in cultured human skeletal muscle cell. METHODS: Myoblast were cultured in SkGM for 4weeks and were differentiated into myocyte in MEM for 4days. The myocytes were treated with PPAR ligand (troglitazone: 5 g/mL) or transduction with adenovirus-PPAR 1 (Ad-PPAR 1). mFABP expression was identified by northern blot. RESULTS: mFABP expression was up-regulated by 4.0+/-1.2 fold in the PPAR ligand (p<0.05). There was increased in mFABP expression with transduction with adenovirus-PPAR 1 while there was no change in mFABP expression which transducted with adenovirus - -galactosidase. CONCLUSION: These results demonstrates that mFABP expression is up-regulated by both PPAR ligand and by PPAR 1 over expression in cultured human skeletal muscle cells.

Abstract PDF: BACKGROUND
Glycogen synthase (GS) is the rate-limiting enzyme controlling non-oxidative glucose disposal in skeletal muscle. Reduction in GS activity and impaired insulin responsiveness are characteristic features of skeletal muscle in type 2 diabetes that contribute to glucose intolerance. These properties also exist in human skeletal muscle cell cultures from type 2 diabetic subjects. The aim of study is to determine the effect of an isolated reduction in GS on glucose metabolism and if this change can generate a diabetes-like state. METHODS: Cultured skeletal muscle cells from non-diabetic subjects were treated with antisense oligodeoxynucleotides (ODN) to GS to interfere with expression of the gene for 6 days. GS activity, protein expression, glycogen synthesis and cellular glycogen content were measured. RESULTS: Treatment with antisense ODN reduced GS protein expression by 70% compared to control (scrambled) ODN (p<0.01). Both total GS activity and that measured at 0.1 mM G-6-P were reduced by antisense ODN treatment. Insulin responsiveness of GS was also halved. Basal GS FV0.1 was decreased in both antisense ODN and control ODN treated cells and antisense treated cells did not show increase in GS FV0.1 in response to insulin stimulation. Glucose incorporation into glycogen under basal conditions was unaltered after antisense ODN treatment, though no further stimulation in response to insulin was observed. Yet both cellular glycogen content and glycogen synthesis were lower in antisense ODN treated cells compared to control ODN treated cells. CONCLUSIONS: Reduction in GS expression in human skeletal muscle cell impair GS activity and insulin responsiveness but does not replicate the abnormalities of glycogen synthesis found in cultured diabetic skeletal muscle cells.

Abstract PDF: BACKGROUND
Neonatal porcine pancreatic tissue may be a potential source of islet transplantation in patients with type 1 diabetes. Gal 1,3 Gal antigen (Gal epitope) is a xenoantigen which is responsible for hyperacute xenograft rejection. The aim of this study is to evaluate the expression of Gal epitope and galactosyl transferase mRNA in porcine neonatal pancreatic tissue. METHOD: Porcine neonatal pancreatic cell clusters (NPCCs) were isolated using collagenase and incubated in various culture condition. They were stained with Gal specific lectin for the detection of Gal epitope. Expression of 1,3 galactosyl transferase mRNA was assessed by semiquantitative RT-PCR. RESULTS: Gal epitope was expressed in both neonatal porcine pancreas and cell clusters. Most of Gal epitope expressed cells were endothelial cells and ductal epithelial cells. A small number of cells stained positive for insulin were also positive for Gal epitope. In some area of monolayer culture of porcine neonatal islet cluster, scattered insulin positive cells coexpressed the Gal epitope. The expression of 1,3 galactosyl transferase mRNA were lower in islet than other tissues. Culture using extracelluar matrix or 3D gel increased the expression of 1,3 galactosyl transferase mRNA levels. CONCLUSION: Gal epitope was expressed in ductal epithelial cells and some of beta cells of porcine neonatal pancreatic tissue. Expression of Gal epitope in porcine neonatal pancreatic cell cluster may be a problem that needs to be solved before porcine NPCCs can be used in human.
