RESUMO
AIM: The efficacy of titratable fixed-ratio combination therapy by a combination preparation of insulin degludec and liraglutide (IDegLira) in Japanese patients with type 2 diabetes, focusing particularly on the change in Fibrosis-4 index (FIB-4), a noninvasive method for the evaluation of liver fibrosis, was investigated. METHODS: As the full analysis set, 113 patients were treated with IDegLira. The patients were categorized into two groups according to the absence (GLP-1RA-naïve group, n = 72) or presence (GLP-1RA-treated group, n = 41) of glucagon-like peptide-1 receptor agonist (GLP-1RA) use before starting IDegLira. The clinical parameters were retrospectively determined over 6 months. RESULTS: The glycated hemoglobin value was significantly reduced in both groups. The bodyweight significantly decreased from 67.4 ± 11.0 kg at baseline to 66.4 ± 11.6 kg at 6 months in the GLP-1RA-naïve group, although it slightly increased in the GLP-1RA-treated group. FIB-4 significantly decreased from 1.60 ± 0.84 at baseline to 1.49 ± 0.74 at 6 months in the GLP-1RA-naïve group. Although FIB-4 significantly increased in the GLP-1RA-treated group, it remained within the low-risk level for liver fibrosis. CONCLUSION: Fixed-ratio combination therapy using IDegLira for the treatment of type 2 diabetes is useful for glycemic control and weight management. In particular, IDegLira may be more effective for lowering FIB-4 than adding unused oral antidiabetic agents or increasing the dose of insulin in GLP-1RA-naïve patients.
RESUMO
Aim: The incidence of cardiovascular and renal events was investigated in patients with type 2 diabetes who were classified according to anemia and the components of dialysis-independent chronic kidney disease (CKD) in a prospective observational study. Methods: A population of 778 Japanese patients with type 2 diabetes was prospectively analyzed for 4 years. The outcomes were the incidence of cardiovascular events and renal events. Results: In all subjects, the incidence of cardiovascular and renal events was found to be 5% and 11%, respectively. Even after adjusting for a reduced estimated glomerular filtration rate (eGFR <60 mL/min/1.73 m2), the incidence of cardiovascular events was significantly higher (hazard ratio [HR]: 5.73) in patients with anemia and albuminuria than in those without anemia and albuminuria. The incidence of renal events was significantly higher in patients with no anemia and albuminuria (HR: 2.93) and further in those with anemia and albuminuria (HR: 7.56) than in those without anemia and albuminuria even after adjusting for a reduced eGFR. Conclusion: Anemia combined with albuminuria is a risk factor for vascular events in patients with type 2 diabetes, regardless of the eGFR.

RESUMO
BACKGROUND: The changes in the estimated glomerular filtration rate (eGFR) and predictors of the renal prognosis were retrospectively assessed over the 12 months after the initiation of tofogliflozin, which has the shortest half-life among sodium-glucose cotransporter 2 (SGLT2) inhibitors, in Japanese patients with type 2 diabetes and renal impairment. METHODS: In total, 158 patients treated with tofogliflozin between 2019 and 2021 were studied as the safety analysis set. One hundred and thirty subjects whose medication was continued over 12 months were investigated as the full analysis set. The subjects were divided into two groups based on the eGFR: normal- (eGFR ≥60 mL/min/1.73 m2, n = 87) and low- (eGFR <60 mL/min/1.73 m2, n = 43) eGFR groups. RESULTS: The body weight, blood pressure, urinary protein excretion, and serum uric acid concentration decreased from baseline in both eGFR groups while the hemoglobin level increased. The eGFR did not significantly differ over time, except for the initial dip (-4.3±9.6 mL/min/1.73 m2 in the normal-eGFR group and -1.5±5.3 mL/min/1.73 m2 in the low-eGFR group). The change in the eGFR at 12 months after the initiation of tofogliflozin was -1.9±9.0 mL/min/1.73 m2 and 0.2±6.0 mL/min/1.73 m2 in the normal- and low-eGFR group, respectively. In the normal-eGFR group, the change in the eGFR showed a significant negative correlation with the HbA1c and eGFR at baseline, according to a multiple regression analysis. In the low-eGFR group, the change in the eGFR showed a significant negative correlation with urate-lowering agent use. The frequencies of adverse events specific for SGLT2 inhibitors were not significantly different between the normal- and low-eGFR groups. CONCLUSIONS: Tofogliflozin may preserve renal function in the medium term in patients with type 2 diabetes and kidney impairment without an increase in specific adverse events.

Introduction The dose of roxadustat, a hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitor, required to treat anemia, the hemoglobin level and the rate of hemoglobin target achievement were retrospectively investigated in non-dialyzed chronic kidney disease (CKD) patients with and without type 2 diabetes. Methods As the full analysis set, 25 subjects (10 with diabetes and 15 without diabetes) were observed over six months among 44 non-dialyzed CKD patients who received roxadustat. The target hemoglobin level was set at 110-130 g/L. Results The comorbidities of diabetes and body weight at baseline were significantly associated with each dose of roxadustat at six months and the change in each dose of roxadustat from the initiation of roxadustat treatment. There was no significant difference in the amount of increase in the hemoglobin level (14±11 g/L vs. 15±8 g/L) and the rate of hemoglobin target achievement (70% vs. 67%) between patients with and without diabetes. Each dose of roxadustat gradually decreased in patients without diabetes, whereas it increased in those with diabetes. Each dose of roxadustat was significantly higher in patients with diabetes than in those without diabetes at 3 (60±21 mg vs. 42±14 mg) and 6 (61±22 mg vs. 41±14 mg) months after the initiation of roxadustat treatment. Conclusion Roxadustat is useful for the treatment of anemia in both CKD patients with and without diabetes. However, the dose required to achieve the target hemoglobin level may be higher in patients with diabetes than in those without diabetes.
RESUMO
Objective Diabetes is recognized as an underlying disease of constipation. However, the prevalence of constipation varies according to the diagnostic criteria applied. We investigated the prevalence of constipation based on the new guideline for constipation in Japanese patients with type 2 diabetes and examined the relationship with the clinical background, including diabetic vascular complications. Methods Questionnaire surveys including items concerning the diagnosis and treatment status of constipation were administered to 410 patients with type 2 diabetes. Results Although 29% of the patients considered that they had experienced constipation (self-judged), only 14% had consulted a physician about constipation. The prevalence of chronic constipation based on the guideline was 26%. After including laxative users, constipation was finally found in 36%. Despite the use of laxatives (n=81), 51% of the patients were still diagnosed with chronic constipation. Patients with constipation (chronic constipation or laxative use) were significantly older and had a longer duration of diabetes than those without constipation. The body mass index (BMI) of patients with constipation (24.9±3.8 kg/m2) was significantly lower than that of those without constipation (26.3±4.6 kg/m2). Diabetic neuropathy (49% vs. 32%) and coronary heart disease (CHD) (27% vs. 13%) were significantly more frequent in the patients with constipation than in those without constipation. A multivariate logistic regression analysis revealed that gender, BMI, diabetic neuropathy, insulin use, and CHD were significantly associated with constipation. Conclusion An accurate diagnosis of constipation is desirable in patients with type 2 diabetes because constipation is independently associated with CHD.

AIMS: The efficacy of dulaglutide was assessed according to the pretreatments administered before the initiation of dulaglutide in patients with type 2 diabetes. METHODS: In total, 89 patients treated using dulaglutide (0.75 mg, once a weekly) were investigated. The subjects were divided into the three groups based on the form in which therapy was started: additional therapy (n = 35), switched from dipeptidyl peptidase-4 (DPP-4) inhibitors (n = 32) and switched from daily glucagon-like peptide-1 receptor agonists (GLP-1 RAs, n = 30). The changes in medication adherence were determined in the daily GLP-1 RAs group using questionnaire surveys. RESULTS: The HbA1c values significantly decreased after the initiation of dulaglutide in all groups (additional therapy group, - 1.4 ± 1.6%; DPP-4 inhibitors group, - 1.2 ± 1.3%; and daily GLP-1 RAs group, - 0.5 ± 0.7%). Forty-six percent of the subjects in the daily GLP-1 RAs group reported that the incidence of forgetting injections of GLP-1 RA was decreased. The reduction of HbA1c was significantly greater in the subjects who reported a decrease in the incidence of forgetting injections (0.9 ± 0.9%) in comparison to those in which there was no change (0.1 ± 0.4%). CONCLUSIONS: Dulaglutide is considered effective in patients with type 2 diabetes and inadequate glycemic control, regardless of whether their pretreatment includes daily GLP-1 RA treatment.
RESUMO
INTRODUCTION: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the cause of coronavirus disease 2019 (COVID-19), is an enveloped, single-stranded RNA virus. Favipiravir is an orally administrable antiviral drug whose mechanism of action is to selectively inhibit RNA-dependent RNA polymerase. A preliminary trial in COVID-19 patients reported significant improvements across a multitude of clinical parameters, but these findings have not been confirmed in an adequate well-controlled trial. We conducted a randomized, single-blind, placebo-controlled Phase III trial assessing the efficacy and safety of favipiravir in patients with moderate pneumonia not requiring oxygen therapy. METHODS: COVID-19 patients with moderate pneumonia (SpO2 ≥ 94%) within 10 days of onset of fever (temperature ≥ 37.5 °C) were assigned to receive either placebo or favipiravir (1800 mg twice a day on Day 1, followed by 800 mg twice a day for up to 13 days) in a ratio of 1:2. An adaptive design was used to re-estimate the sample size. The primary endpoint was a composite outcome defined as the time to improvement in temperature, oxygen saturation levels (SpO2), and findings on chest imaging, and recovery to SARS-CoV-2-negative. This endpoint was re-examined by the Central Committee under blinded conditions. RESULTS: A total of 156 patients were randomized. The median time of the primary endpoint was 11.9 days in the favipiravir group and 14.7 days in the placebo group, with a significant difference (p = 0.0136). Favipiravir-treated patients with known risk factors such as obesity or coexisting conditions provided better effects. Furthermore, patients with early-onset in the favipiravir group showed higher odds ratio. No deaths were documented. Although adverse events in the favipiravir group were predominantly transient, the incidence was significantly higher. CONCLUSIONS: The results suggested favipiravir may be one of options for moderate COVID-19 pneumonia treatment. However, the risk of adverse events, including hyperuricemia, should be carefully considered. TRIAL REGISTRATION: Clinicaltrials.jp number: JapicCTI-205238.
RESUMO
AIMS: The safety and efficacy, particularly, the factors associated with the renal prognosis, were assessed over 12 months after the initiation of luseogliflozin therapy in Japanese patients with type 2 diabetes and renal impairment. METHODS: In total, 238 patients treated with luseogliflozin (2.5 mg, once daily) were studied as the safety analysis set. Two hundred and two subjects whose medication was continued over 12 months were investigated as the full analysis set. The subjects were divided into 3 groups based on the estimated glomerular filtration rate (eGFR): high eGFR (n = 49), normal eGFR (n = 116) and low eGFR (n = 37) groups. RESULTS: The body weight, systolic blood pressure, HbA1c and urinary protein excretion gradually decreased from baseline in all eGFR groups. While the eGFR was significantly reduced from baseline in the high and normal eGFR groups, the eGFR did not significantly differ over time in the low eGFR group. There was no marked difference in the frequency of adverse events that were specific for SGLT2 inhibitors among the 3 groups in the safety analysis set. CONCLUSIONS: Luseogliflozin can preserve the renal function in the medium term in patients with type 2 diabetes and renal impairment without an increase in specific adverse events.

A 77-year-old man was treated with a DPP-4 inhibitor for type 2 diabetes. Hypoglycemia occurred frequently, and an examination revealed a tumor with a maximum diameter of 140 mm in both lobes of the liver. Western immunoblotting detected a high-molecular-weight form of insulin-like growth factor-II, and non-islet cell tumor hypoglycemia was diagnosed. Although prednisolone 40 mg was started, hypoglycemia continued to occur frequently. Surgical tumor removal was not indicated, so lenvatinib was initiated. Hypoglycemia improved quickly, and the tumor shrank until it had partially disappeared. His condition continued to improve, and he was discharged.

BACKGROUND: To determine the renal and cardiovascular prognosis and all-cause mortality of Japanese patients with type 2 diabetes showing a reduced estimated glomerular filtration rate (eGFR) without albuminuria. METHODS: A population of 675 patients with type 2 diabetes was prospectively observed for 4 years to determine the renal and cardiovascular outcomes and mortality. The subjects were divided into the four groups: those with a preserved eGFR and no albuminuria (n = 306), a preserved eGFR and albuminuria (n = 151), a reduced eGFR and no albuminuria (n = 96), and a reduced eGFR and albuminuria (n = 122). The Cox proportional hazard model and Fine and Gray method were used to assess between-group differences in the risk of mortality and cardiovascular events. RESULTS: In the group with a reduced eGFR, the eGFR value did not significantly change in the subjects without albuminuria (0 ± 8 mL/min/1.73 m2), whereas it decreased continuously in those with albuminuria (-6 ± 12 mL/min/1.73 m2). The incidence of cardiovascular events was significantly (P = 0.03) higher in the subjects with albuminuria (17%) than those without albuminuria (7%) in the group with a reduced eGFR. Cardiovascular events were significantly (P < 0.01) more frequent in the group with a reduced eGFR than in those with a preserved eGFR in both subjects with and without albuminuria. CONCLUSIONS: The risk of end-stage kidney disease in non-albuminuric subjects with a reduced eGFR is considered to be low. We should focus on cardiovascular prognosis, because these patients are still at high risk of cardiovascular events, even though the prognosis is better in comparison to albuminuric patients.

PURPOSE: The factors associated with the renal prognosis over six months after the initiation of empagliflozin were compared between the non-elderly and elderly Japanese patients with type 2 diabetes. PATIENTS AND METHODS: In total, 132 patients treated with empagliflozin (10 mg, once daily) were studied as the safety analysis set. One hundred ten subjects whose medications were not changed during the observation period were investigated as the full analysis set to assess the effectiveness. The subjects were divided into two groups: non-elderly subjects (n=72) of<65 years of age and elderly subjects (n=38) of≥65 years of age. RESULTS: Although the body weight and HbA1c, AST, ALT and γ-GTP levels were significantly reduced in both the non-elderly and elderly subjects, blood pressure, eGFR and urinary protein excretion were only significantly decreased in the non-elderly subjects. The hemoglobin, hematocrit and serum HDL-cholesterol levels were significantly elevated in both groups. The change in eGFR showed a significant positive association with the change in blood pressure. The change in urinary protein excretion tended to be correlated with the change in blood pressure. CONCLUSION: Although renoprotective effects might be limited, empagliflozin can safely and effectively improve metabolic parameters, even in elderly subjects.
RESUMO
AIMS: The changes in patients' satisfaction with the treatment, medication adherence and unused drugs before and after switching from daily DPP-4 inhibitors to once-weekly trelagliptin administration were prospectively investigated in patients with type 2 diabetes. METHODS: After excluding 46 patients who declined to switch from daily DPP-4 inhibitors, 79 subjects were included in the present study. The clinical parameters and results of questionnaire surveys regarding satisfaction with treatment as well as impressions of the amount of medicine/number of doses, medication adherence, and unused drug were examined at the baseline and 3â¯months after switching from daily DPP-4 inhibitors to trelagliptin in 75 patients with type 2 diabetes. RESULTS: Although the value of HbA1c did not change (7.0%⯱â¯0.5% to 7.0%⯱â¯0.6%), the scores representing satisfaction with the treatment (25.2⯱â¯6.4 to 26.4⯱â¯6.0), impression of the amount of medicine (-0.3⯱â¯1.0 to 0.3⯱â¯1.0) and number of doses (0.3⯱â¯1.0 to 0.8⯱â¯0.6), and medication adherence (0.8⯱â¯0.4 to 0.9⯱â¯0.3) as assessed by the questionnaire surveys were significantly improved after switching from DPP-4 inhibitors. The self-reported amount of unused drugs was significantly reduced after switching. CONCLUSIONS: Switching from daily DPP-4 inhibitors to once-weekly trelagliptin improved the satisfaction with the treatment, impression of the prescribed medicine and medication adherence in the type 2 diabetic patients who expresses a desire to reduce their prescription medicines. In such patients, improvements in the glycemic control and long-term prognosis might be expected through the reduction of unused drugs.

Objective: We compared the clinical course of type 2 diabetic patients whose basal insulin preparations were replaced from insulin glargine (IGlar) 100 units/mL (U100) to IGlar biosimilar or IGlar 300 units/mL (U300). Methods: After propensity score matching, 34 patients whose basal insulin preparation was switched from IGlar U100 to IGlar biosimilar and 102 switched to IGlar U300 were observed for 6 months. Results: The HbA1c level and body weight did not change significantly after the replacement in the IGlar biosimilar or IGlar U300 groups. In the IGlar biosimilar group, the frequency of subjects who experienced hypoglycemia after the replacement (12%) was not different from before (12%). However, the frequency was significantly lower after the replacement (2%) than before (13%) in the IGlar U300 group. The change in the HbA1c level after the replacement showed a significant association with the HbA1c level at the baseline but not with the kind of IGlar. Hypoglycemia was frequently observed in subjects who had experienced hypoglycemia before the replacement. Conclusions: IGlar biosimilar and IGlar U300 induced similar HbA1c and body weight changes among type 2 diabetic patients. IGlar biosimilar is a suitable option for patients with a low risk for hypoglycemia.
RESUMO
AIM: The association between cognitive function and clinical parameters of chronic kidney disease (CKD) was investigated in Japanese patients without overt dementia in a cross-sectional study. MATERIALS AND METHODS: A population of 497 patients whose cognitive function had been examined using the mini-mental state examination (MMSE) were screened for this study. After the exclusion of 306 subjects who showed overt dementia, the association between the MMSE score and clinical characteristics was investigated in 191 subjects (male: 55%, age: 69 ± 12 years). RESULTS: The mean MMSE score of the study subjects was 26.7 ± 2.0. The MMSE score was negatively correlated with the patients' age and positively with the estimated glomerular filtration rate. It was significantly associated with age and proteinuria based on a multivariate analysis. The scores of "temporal orientation", "attention and calculation", and "remote memory" subitems of MMSE were significantly lower in the subjects ≥ 70 years of age than in those < 70 years of age. The scores of "temporal orientation" (4.3 ± 0.8 vs. 4.7 ± 0.6), "attention and calculation" (2.9 ± 1.6 vs. 3.9 ± 1.5), and "stage command" (2.7 ± 0.5 vs. 2.9 ± 0.3) were significantly lower in the subjects with proteinuria than in those without. CONCLUSION: Cognitive function was disturbed even in CKD patients without overt dementia. Intervention in patients with risk factors is deemed important for preventing future reductions in cognitive and renal functions in CKD patients without dementia.â©.

BACKGROUND: We aimed to study the association between urinary liver-type fatty acid-binding protein (L-FABP), a biomarker of tubulointerstitial injury, and the clinical characteristics of normoalbuminuric and albuminuric patients with type 2 diabetes in order to detect the factors affecting urinary L-FABP. METHODS: Urinary L-FABP levels were measured in 788 patients with type 2 diabetes and again in 666 patients at 6 months after the initial measurement. The association between the urinary L-FABP level and the clinical parameters was investigated in a retrospective cross-sectional study and a subsequent observation. RESULTS: The HbA1c (odds ratio (OR): 1.42; 95% confidence interval (CI): 1.11 - 1.79; P < 0.01), systolic blood pressure (OR: 1.03; 95% CI: 1.01 - 1.05; P < 0.01) levels and estimated glomerular filtration rate (OR: 0.98; 95% CI: 0.96 - 1.00; P = 0.01) were significantly associated with the high levels of urinary L-FABP (> 8.4 µg/gCr) in normoalbuminuric patients. However, a logistic regression analysis revealed that use of renin-angiotensin system (RAS) inhibitors (OR: 2.22; 95% CI: 1.16 - 4.89; P = 0.02), urinary albumin-to-creatinine ratio (ACR) (OR: 1.01; 95% CI: 1.00 - 1.01; P < 0.01) and serum HDL-cholesterol concentration (OR: 0.33; 95% CI: 0.11 - 0.89; P = 0.03) were significantly associated in albuminuric patients. In the follow-up observation, the change in urinary L-FABP was found to be significantly (P < 0.01) influenced by the change in the HbA1c level in both the normoalbuminuric and albuminuric patients. CONCLUSIONS: High urinary L-FABP is associated with part of the current metabolic abnormalities, including high levels of HbA1c and systolic blood pressure among normoalbuminuric patients with type 2 diabetes.
RESUMO
AIMS: The aim of the present study was to clarify the relationships between the duration of diabetes and the current statuses of diabetes in elderly (aged ≥65 years) patients with type 2 diabetes. METHODS: Clinical characteristics were cross-sectionally examined in 1436 patients (684 elderly and 752 non-elderly) with type 2 diabetes. RESULTS: As the duration of diabetes increased, the patients' age, frequency of receiving insulin therapy and glycated hemoglobin value increased in both the elderly and non-elderly groups, whereas the urinary C-peptide immunoreactivity and glomerular filtration rate decreased. The duration of diabetes (years) was significantly associated with the prevalence of diabetic retinopathy (OR 1.05, 95% CI 1.03-1.07, P < 0.01), nephropathy (OR 1.03, 95% CI 1.01-1.05, P < 0.01) and neuropathy (OR 1.08, 95% CI 1.05-1.12, P < 0.01), but not with cerebrovascular disease (OR 1.01, 95% CI 0.99-1.03, P = 0.38), coronary heart disease (OR 1.02, 95% CI 1.00-1.04, P = 0.09) or peripheral artery disease (OR 1.02, 95%CI 0.99-1.05, P = 0.12) in the elderly patients after adjusting for the traditional risk factors of diabetic angiopathies. In contrast, the duration of diabetes showed a significant association with the prevalence of both diabetic micro- and macroangiopathies in the non-elderly patients. CONCLUSIONS: It should be noted that atherosclerotic diseases are present in the clinical setting for the management of elderly diabetic patients independent of the duration of diabetes.

Objective The effects of febuxostat therapy on hyperuricemia in patients with and without type 2 diabetes were compared in this retrospective observational study after pair-matching using the propensity scores. Methods In total, 160 patients with hyperuricemia were studied as the treated set, and the 155 subjects in whom the administration of febuxostat was not discontinued during the observation period were investigated in the full analysis. The study subjects were divided into two groups based on the style of initiation of febuxostat: initial and switching therapy from allopurinol administration. Results The reduction in the serum uric acid (sUA) levels at six months after the initiation of febuxostat administration did not significantly differ between the patients with and without diabetes in both the initial (206±114 and 226±113 µmol/L in patients with and without diabetes, respectively) and switching (154±91 and 129±90 µmol/L in patients with and without diabetes, respectively) therapy groups. The eGFR values were significantly increased compared to the baseline levels only in the patients without diabetes. The changes in the eGFR values were significantly associated with the presence of diabetes and sUA at baseline in a multivariate analysis. The frequency of adverse events was not significantly different between the patients with and without diabetes. Conclusion Although febuxostat exerted a similar sUA-lowering effect against hyperuricemia in patients with type 2 diabetes compared to those without, the renoprotective effect was attenuated in those with diabetes compared to nondiabetic subjects.

BACKGROUND: We investigated the trends in the clinical characteristics and prescriptions of type 2 diabetic patients with severe hypoglycemia because the prescription rate of antidiabetic agents has significantly changed recently. METHODS: A total of 193 patients with type 2 diabetes with severe hypoglycemia induced by antidiabetic agents between 2008 and 2013 were divided into three groups based on the period of visit: 2008 - 2009, 2010 - 2011 and 2012 - 2013. RESULTS: While the proportion of patients with severe hypoglycemia using insulin (from 55% to 74%), biguanides (from 6% to 20%), glinides, and dipeptidyl peptidase-4 inhibitors significantly increased, those using sulfonylureas (from 45% to 20%) significantly decreased. Errors of drug use significantly increased as a trigger of hypoglycemia in recent years. The number of antidiabetic agents (from 1.9 ± 0.6 to 2.3 ± 0.7), non-diabetic agents (from 2.3 ± 2.4 to 4.3 ± 3.3), and total drugs prescribed were significantly higher in recent years among patients receiving insulin therapy. CONCLUSIONS: Polypharmacy especially in patients receiving insulin therapy and errors of drug use have increased in type 2 diabetic patients with severe hypoglycemia in recent years. Intensive education in the usage rule of drugs is considered to be important in order to prevent severe hypoglycemia.

We aimed to clarify the usefulness of measuring the flow mediated dilatation (FMD) in patients with type 2 diabetes mellitus without and with coronary heart disease (CHD). The FMD was measured in 480 patients with type 2 diabetes and in 240 nondiabetic subjects. The FMD was significantly lower in the subjects with CHD (n = 145, 5.4 ± 3.2%) than in those without CHD (n = 95, 6.9 ± 3.5%) among the nondiabetic subjects. The FMD was also lower in the subjects both with CHD (n = 161, 5.6 ± 2.8%) and without CHD (n = 319, 6.1 ± 3.3%) among the patients with diabetes compared to those without both diabetes and CHD. The FMD showed a significant positive correlation with the estimated glomerular filtration rate (eGFR) in the diabetic patients without CHD, while there was no significant association in those with CHD. The FMD was significantly lower with the progressive stages of the GFR or albuminuria in the patients without CHD among those with diabetes, although the FMD was not different in those with CHD. In conclusion, the FMD is considered to be useful for the detection of atherosclerosis in patients with type 2 diabetes, even if overt macroangiopathy is not diagnosed.
