Relationship Between Frailty and Diabetic Pharmacologic Therapy in Older Adults with Type 2 Diabetes: A Cross-Sectional Study.

BACKGROUND: Older adults with diabetes mellitus require drug treatment considering their frailty, cognitive function, and hypoglycemia. OBJECTIVE: We investigated the association between diabetic pharmacologic therapy and both diabetic complications and frailty across eight diabetes-specific outpatient clinics nationwide. METHODS: Participants (aged 60-80 years) who had type 2 diabetes and did not require nursing care were included in the study. Basic attributes, patient background, complications, hypoglycemic status, body weight, body composition, blood tests, grip strength, and Kihon Checklist (a frailty index) and self-care scores were obtained. Descriptive statistics, t-test, chi-square test, and regression analyses were employed for evaluation. RESULTS: Overall, 417 participants were included (224 men, 193 women, mean age 70.1 ± 5.4 years, diabetes duration 14.9 ± 10.9 years, body mass index 24.5 ± 3.8, glycated hemoglobin 7.22 ± 0.98%, proportion of individuals with frailty and prefrailty, 19.9% and 41.0%, respectively). All drugs were used more frequently in prefrailty conditions. Each diabetes medication was related to complications, body composition, and frailty, as follows: sulfonylurea (lower hypoglycemia); glinide (severe hypoglycemia, retinopathy, weaker grip strength, high Kihon Checklist score, decreased physical activities); alpha-glucosidase inhibitors (no association); biguanide (high body mass index, high body fat, stronger grip strength); thiazolidinedione (decreased instrumental activities of daily living); dipeptidyl-peptidase-4 inhibitors (no association); sodium-glucose cotransporter 2 inhibitors; retinopathy, high body mass index and Kihon Checklist score, and depressive mood); glucagon-like peptide-1 receptor agonists (high body mass index and body fat and poor nutritional status); and insulin preparations (hypoglycemia, retinopathy, neuropathy, nephropathy, cardiovascular diseases, weaker grip strength, and high Kihon Checklist score and physical inactivity). CONCLUSIONS: Some formulations, such as glinide, sodium-glucose cotransporter 2 inhibitors, and insulin, are associated with an increased frequency of frailty, warranting careful and individualized diabetes treatment.

Active Consumption of Konjac and Konjac Products Improves Blood Glucose Control in Patients with Type 2 Diabetes Mellitus.

OBJECTIVE: Konjac is a food mainly consumed in Asian countries with high fiber and low energy. Although glucomannan, a component of konjac, have been used for several clinical studies, there is few reports using konjac itself. This study examined the effects of the active consumption of konjac in patients with type 2 diabetes mellitus (T2DM). METHODS: The study included 26 Japanese patients with T2DM. Participants were recommended to take konjac at least once a day using free konjac products (various noodles, rice, and desserts) and plate konjac for 12 weeks. RESULTS: HbA1c and fasting plasma glucose levels significantly decreased from 8.3 ± 0.9% to 8.0 ± 0.8% and from 173.2 ± 44.4 to 152.8 ± 36.7 mg/dL, respectively. No significant changes were observed in body weight and insulin resistance indices, but the index for insulin secretion significantly increased. Serum high molecular weight adiponectin levels significantly increased. Plasma ghrelin, leptin and glucagon-like peptide-1 levels tended to decrease (p = 0.084), decrease (p = 0.057) and increase (p = 0.071), respectively. Actual konjac intake positively correlated with age (r = 0.61, p = 0.001). Body weight and HbA1c significantly decreased in patients aged ≥50 years than in those aged <50 years, and the changes significantly inversely correlated with age. CONCLUSION: Active consumption of konjac and konjac products seems to be a useful dietary therapy with multifaceted action for T2DM. Further studies with greater sample size and long-term are needed to confirm these findings.
