RESUMEN
AIM: To conduct a post hoc subgroup analysis of patients with type 2 diabetes (T2D) from the RECAP study, who were treated with sodium-glucose cotransporter-2 (SGLT2) inhibitor and glucagon-like peptide 1 receptor agonist (GLP-1RA) combination therapy, focusing only on those patients who had chronic kidney disease (CKD), to examine whether the composite renal outcome differed between those who received SGLT2 inhibitor treatment first and those who received a GLP-1RA first. METHODS: We included 438 patients with CKD (GLP-1RA-first group, n = 223; SGLT2 inhibitor-first group, n = 215) from the 643 T2D patients in the RECAP study. The incidence of the composite renal outcome, defined as progression to macroalbuminuria and/or a ≥50% decrease in estimated glomerular filtration rate (eGFR), was analysed using a propensity score (PS)-matched model. Furthermore, we calculated the win ratio for these composite renal outcomes, which were weighted in the following order: (1) both a ≥50% decrease in eGFR and progression to macroalbuminuria; (2) a decrease in eGFR of ≥50% only; and (3) progression to macroalbuminuria only. RESULTS: Using the PS-matched model, 132 patients from each group were paired. The incidence of renal composite outcomes did not differ between the two groups (GLP-1RA-first group, 10%; SGLT2 inhibitor-first group, 17%; odds ratio 1.80; 95% confidence interval [CI] 0.85 to 4.26; p = 0.12). The win ratio of the GLP-1RA-first group versus the SGLT2 inhibitor-first group was 1.83 (95% CI 1.71 to 1.95; p < 0.001). CONCLUSION: Although the renal composite outcome did not differ between the two groups, the win ratio of the GLP-1RA-first group versus the SGLT2 inhibitor-first group was significant. These results suggest that, in GLP-1RA and SGLT2 inhibitor combination therapy, the addition of an SGLT2 inhibitor to baseline GLP-1RA treatment may lead to more favourable renal outcomes.

Decrease in blood pressure contributes to the reno-protective effects of sodium-glucose cotransporter 2 inhibitors; however, its relationship with home monitoring of blood pressure is unclear. We retrospectively analyzed 101 visiting members of the Kanagawa Physicians Association with type 2 diabetes mellitus and chronic kidney disease who were taking sodium-glucose cotransporter 2 inhibitors and who monitored blood pressure at home for a median treatment period of 14 months. At baseline, the mean value of HbA1c was 59.3 mmol/mol (7.6%) and the median value of albumin-creatinine ratio was 30.9 mg/gCr that was evaluated in 88 patients. The mean blood pressure both at office and home significantly decreased, and there was a significant positive correlation between the change in albumin-creatinine ratio and both blood pressures. Controlled hypertension, masked hypertension, white coat hypertension, and sustained hypertension were observed in 10.9%, 13.9%, 12.9%, and 62.4% of patients at the initiation of therapy, which changed to 10.9%, 16.8%, 17.8%, and 54.5% at the time of the survey, respectively. In conclusion, management of blood pressure both at office and home was found to be important for the reno-protective effects of sodium-glucose cotransporter 2 inhibitors along with strict blood pressure management.

Accumulating evidence has demonstrated that both SGLT2 inhibitors (SGLT2i) and GLP-1 receptor agonists (GLP1Ra) have protective effects in patients with diabetic kidney disease. Combination therapy with SGLT2i and GLP1Ra is commonly used in patients with type 2 diabetes (T2D). We previously reported that in combination therapy of SGLT2i and GLP1Ra, the effect on the renal composite outcome did not differ according to the preceding drug. However, it remains unclear how the initiation of combination therapy is associated with the renal function depending on the preceding drug. In this post hoc analysis, we analyzed a total of 643 T2D patients (GLP1Ra-preceding group, n = 331; SGLT2i-preceding group, n = 312) and investigated the differences in annual eGFR decline. Multiple imputation and propensity score matching were performed to compare the annual eGFR decline. The reduction in annual eGFR decline in the SGLT2i-preceding group (pre: -3.5 ± 9.4 mL/min/1.73 m2/year, post: -0.4 ± 6.3 mL/min/1.73 m2/year, p < 0.001), was significantly smaller after the initiation of GLP1Ra, whereas the GLP1Ra-preceding group tended to slow the eGFR decline but not to a statistically significant extent (pre: -2.0 ± 10.9 mL/min/1.73 m2/year, post: -1.8 ± 5.4 mL/min/1.73 m2/year, p = 0.83) after the initiation of SGLT2i. After the addition of GLP1Ra to SGLT2i-treated patients, slower annual eGFR decline was observed. Our data raise the possibility that the renal benefits-especially annual eGFR decline-of combination therapy with SGLT2i and GLP1Ra may be affected by the preceding drug.
RESUMEN
Propylthiouracil (PTU) is recommended as a first-line antithyroid drug (ATD) during first trimester organogenesis in pregnancy because recent evidence suggests that methimazole (MMI) may be associated with congenital anomalies. However, PTU more commonly causes myeloperoxidase (MPO)-antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis, which usually occurs during prolonged treatment, compared with MMI. We report a case of MPO-ANCA-associated vasculitis in a 35-year-old woman with Graves'disease. Although her thyroid function could be maintained euthyroid by MMI, her ATD was switched to PTU because she wished to become pregnant. The patient presented with flu-like symptoms 8 days after starting PTU and developed hemoptysis and dyspnea at 22 days. Her MPO-ANCA titer was 21 ELISA units (EUs) before PTU treatment but increased to 259 EUs at 22 days after PTU treatment. Her clinical condition improved with the discontinuation of PTU and with immunosuppressive therapy. This case indicated that MPO-ANCA vasculitis occurred within several weeks after the initiation of PTU and that this side effect could be caused by the change from MMI to PTU. Thus, our clinical observation suggests that patients treated with PTU should be carefully monitored for MPO-ANCA titers and variable manifestations of MPO-ANCA-associated vasculitis regardless of the period of administration.

(1) Background: Renal dysfunction and hypertension are mutually aggravating factors; however, the details of their interaction remain unclear. In a study using renal tissue from diabetic rats, we found that ß1-integrin, a cell-substrate adhesion molecule, is specifically phosphorylated in juxtaglomerular cells that secrete renin, a blood pressure regulator. (2) Methods: A mouse juxtaglomerular cell line (As4.1 cells) was used for the following experiments: drug-induced promotion of ß1-integrin phosphorylation/dephosphorylation; knockdown of ß1-integrin and the cell adhesion molecule connexin-40 (a candidate for the main body of baroreceptor); and pressurization to atmospheric pressure + 100 mmHg. culture in hypotonic liquid medium. The expression of renin under these conditions was measured by qRT-PCR. (3) Results: Phosphorylation of ß1-integrin suppressed the expression of renin, while dephosphorylation conversely promoted it. ß1-integrin and connexin-40 knockdown both promoted the expression of renin. Pneumatic pressurization and hypotonic medium culture both decreased the expression of renin, which was restored by the knockdown of ß1-integrin. (4) Conclusions: ß1-integrin plays an inhibitory role in the regulation of the expression of renin, which may be controlled by phosphorylation and dephosphorylation. It is hypothesized that ß1-integrin and other adhesion factors regulate the expression of renin by altering the sensitivity of baroreceptors on the plasma membrane.
RESUMEN
Two-thirds of urate is excreted via the renal pathway and the remaining one-third via the extra-renal pathway, the latter mainly via the intestine in healthy individuals. ABCG2, a urate exporter, is expressed in various tissues including the kidney and intestine, and its dysfunction leads to hyperuricemia and gout. ABCG2 is regarded as being responsible for most of the extra-renal urate excretion. However, the extra-renal urate excretion capacity via ABCG2 remains undefined in end-stage kidney diseases. Therefore, we evaluated the capacity of extra-renal ABCG2 using 123 anuric hemodialysis patients whose urate excretion depended on only the extra-renal pathway. ABCG2 function in each participant was estimated based on ABCG2 dysfunctional variants. We computed the uric acid pool (PoolUA) from bodyweight and serum urate level (SUA) using previously reported radio-isotopic data, and we analyzed the association between ABCG2 function and the PoolUA. SUA and PoolUA increased significantly with ABCG2 dysfunction, and extra-renal ABCG2 could excrete up to approximately 60% of the daily uric acid turnover in hemodialysis patients. Our findings indicate that the extra-renal urate excretion capacity can expand with renal function decline and highlight that the extra-renal pathway is particularly important in the uric acid homeostasis for patients with renal dysfunction.

Aims: This study aimed to clarify the renal influence of glucagon-like peptide 1 receptor agonists (GLP1Ras) with or without sodium-glucose co-transporter 2 inhibitors (SGLT2is) on Japanese patients with type 2 diabetes mellitus (T2DM). Methods: We retrospectively extracted 547 patients with T2DM who visited the clinics of members of Kanagawa Physicians Association. The progression of albuminuria status and/or aâ ≥â 15% decrease in the estimated glomerular filtration rate (eGFR) per year was set as the renal composite outcome. Propensity score matching was performed to compare GLP1Ra-treated patients with and without SGLT2i. Results: After matching, 186 patients in each group were compared. There was no significant difference of the incidence of the renal composite outcomes (17% vs. 20%, Pâ =â 0.50); however, the annual decrease in the eGFR was significantly smaller and the decrease in the urine albumin-to-creatinine ratio was larger in GLP1Ra-treated patients with the concomitant use of SGLT2is than in those without it (-1.1â ±â 5.0 vs. -2.8â ±â 5.1â mL/min/1.73 m2, Pâ =â 0.001; and -0.08â ±â 0.61 vs. 0.05â ±â 0.52, Pâ =â 0.03, respectively). Conclusion: The concomitant use of SGLT2i with GLP1Ra improved the annual decrease in the eGFR and the urine albumin-to-creatinine ratio in Japanese patients with T2DM.
RESUMEN
AIMS: Combination therapy with sodium-glucose cotransporter inhibitors (SGLT2is) and GLP-1 receptor agonists (GLP1Ras) is now of interest in clinical practice. The present study evaluated the effects of the preceding drug type on the renal outcome in clinical practice. METHODS: We retrospectively extracted type 2 diabetes mellitus patients who had received both SGLT2i and GLP1Ra treatment for at least 1 year. A total of 331 patients in the GLP1Ra-preceding group and 312 patients in the SGLT2i-preceding group were ultimately analyzed. Either progression of the albuminuria status and/or a ≥30% decrease in the eGFR was set as the primary renal composite outcome. The analysis using propensity score with inverse probability weighting was performed for the outcome. RESULTS: The incidences of the renal composite outcome in the SGLT2i- and GLP1Ra-preceding groups were 28% and 25%, respectively, with an odds ratio [95% confidence interval] of 1.14 [0.75, 1.73] (p = .54). A logistic regression analysis showed that the mean arterial pressure (MAP) at baseline, the logarithmic value of the urine albumin-to-creatinine ratio at baseline, and the change in MAP were independent factors influencing the renal composite outcome. CONCLUSION: With combination therapy of SGLT2i and GLP1Ra, the preceding drug did not affect the renal outcome.

Background: The mortality rate of novel coronaviral disease (COVID-19) patients undergoing dialysis is considerably higher than that of patients with normal kidney function. As of August 2021, only remdesivir has been approved in Japan as an antiviral drug for the treatment of COVID-19. However, in cases of kidney failure, remdesivir administration should be considered only if the therapeutic benefits outweigh the risks because of concern about the accumulation of its solubilizing excipient sulfobutylether-beta-cyclodextrin and subsequent renal tubular injury or liver injury. Recently, reports from overseas indicating the safety of the use of remdesivir for COVID-19 patients on dialysis have been gathered. Case presentation: From June 2021, in our hospital, we started the administration of remdesivir to patients with moderate cases of COVID-19 undergoing hemodialysis, with careful consideration of the dosage and timing. Since then, six out of seven COVID-19 patients on hemodialysis who had received remdesivir have completely recovered. In a patient who died, the initial dose of remdesivir was administered after the case developed into severe COVID-19. All six patients who were able to start receiving remdesivir immediately at the stage of moderate COVID-19 recovered and were discharged without the need for mechanical ventilation. While, two out of four patients before May 2021 who had not been administered remdesivir at admission became severe, transferred to another tertiary hospital, and died. During and after remdesivir administration, no increase in serum transaminase to five times or more of the normal upper limit was observed in any of the cases. There were no other adverse drug reactions, such as infusion reaction, gastrointestinal symptoms, or anemia. Conclusions: We were able to administer remdesivir to six Japanese patients with moderate COVID-19 on hemodialysis safely. It is expected that the safe use of remdesivir will bring an increase in treatment options for moderate cases of COVID-19 in dialysis patients as well as subsequent improvement in treatment outcomes. However, to confirm the efficacy and safety of such use, further careful observation in more cases is required.
RESUMEN
Despite some negative reports regarding the need for the self-monitoring of blood glucose (SMBG), including the issue of cost-effectiveness, there are still many users, and in diabetes treatment, which is largely dependent on the patient's self-care, SMBG remains an important tool in establishing such self-care habits, with several reports supporting this notion. In addition, devices are needed to assist in SMBG for patients with diabetes who have difficulty performing SMBG, such as the elderly or those with visual impairment. In current diabetes care, it is reported that patient-centered care that respects the preferences, needs, and values of individual patients and personalized care that consider the characteristics and comorbidities of each patient are important. Through a case study of a patient with diabetes who had difficulty performing SMBG due to visual impairment, we learned of the needs of SMBG and its assistive devices and the importance of patient and family engagement with emphasis on patient-centered and personalized care. We herein report what we learned through this case in the form of perspectives. Through this report, we hope that medical professionals involved in diabetes care will learn of the importance and needs of these issues and apply them to their actual clinical practice.
RESUMEN
AIMS/INTRODUCTION: We previously reported that sodium-glucose cotransporter 2 inhibitor (SGLT2i) treatment was associated with an improvement of the albumin-to-creatinine ratio in Japanese patients with type 2 diabetes mellitus and chronic kidney disease. The present study clarified how concomitant insulin treatment (IT) with SGLT2i therapy influences the renal composite outcome (RCO). MATERIALS AND METHODS: We retrospectively evaluated 624 Japanese patients with type 2 diabetes mellitus and chronic kidney disease who underwent SGLT2i treatment. The renal composite outcome was set as progression of the stage of albuminuria or a ≥15% decrease in the estimated glomerular filtration rate per year. We developed a cohort model of patients managed with and without IT (Ins [+], Ins [-]) using propensity score matching methods. Furthermore, all patients in our study population were stratified into quintiles according to their propensity score. RESULTS: The incidence of the RCO was in Ins (+) patients significantly higher than that in Ins (-) (P = 0.033). The estimated hazard ratio for the RCO was 1.55 (P = 0.035) in Ins (+) patients. The change in the estimated glomerular filtration rate and albumin-to-creatinine ratio in the groups was not statistically significant. The analysis, which was based on the quintiles, showed a statistically significant difference between the Ins (+) and Ins (-) groups (P = 0.01); the odds ratio for the RCO in patients managed with IT was 2.20 (P = 0.01). CONCLUSIONS: Concomitant administration of IT with SGLT2is influenced the RCO in Japanese patients with type 2 diabetes mellitus and chronic kidney disease. We might need to consider the influence of concomitant agents on the renoprotective effects of SGLT2i therapy.

AIMS: This study aimed to clarify the differences in how sodium glucose co-transporter 2 inhibitors (SGLT2i) and glucagon-like peptide 1 receptor agonists (GLP1Ra) influence kidney function in Japanese patients with type 2 diabetes mellitus (T2DM). METHODS: We retrospectively built two databases of patients with T2DM who visited the clinics of members of Kanagawa Physicians Association. We defined the renal composite outcome as either progression of albuminuria status and/or > 15% deterioration in estimated glomerular filtration rate (eGFR) per year. We used propensity score matching to compare patient outcomes after SGLT2i and GLP1Ra treatments. RESULTS: The incidence of renal composite outcomes was significantly lower in SGLT2i-treated patients than in GLP1Ra-treated patients (n = 15[11%] and n = 27[20%], respectively, P = 0.001). Annual eGFR changes (mL/min/1.73 m2/year) between the two groups differed significantly (-1.8 [95 %CI, -2.7, -0.9] in SGLT2i-treated patients and - 3.4 [95 %CI, -4.6, -2.2] in GLP1Ra-treated patients, P = 0.0049). The urine albumin-to-creatinine ratio changed owing to a significant interaction between the presence or absence of a decrease in systolic blood pressure and the difference in treatments (P < 0.04). CONCLUSION: Renal composite outcome incidence was lower in SGLT2i-treated patients than in GLP1Ra-treated patients.

Introduction: It is extremely important for patients with diabetes undergoing maintenance hemodialysis (MHD) to receive regular ophthalmologic examinations. However, even in the field of MHD in Japan, where there are many hemodialysis patients and the survival rate is said to be one of the highest in the world, we often see patients with diabetes who do not receive regular ophthalmologic examinations. In this study, we surveyed the status of ophthalmology consultations and the use of diabetic eye notebook (DEN) among hemodialysis patients with diabetes at hemodialysis clinics to confirm the current situation, with the aim of confirming the effectiveness of education on consultation behavior by medical care staff. Materials and Methods: This study included 38 diabetic hemodialysis patients attending one MHD clinic in Japan for one year from March 2018 to March 2019. In the first fact-finding survey in March 2018, hemodialysis care unit nurses (HCUNs) in the hemodialysis unit asked the diabetic hemodialysis patients whether they had consulted an ophthalmologist and used the DEN. Based on the results, the HCUNs recommended that hemodialysis patients with complications of diabetes be educated about the usefulness of regular ophthalmologic examinations, even during MHD, and that they use the DEN. This was followed by a second fact-finding survey in March 2019 to reconfirm ophthalmology consultations and DEN use. Results: Regarding the presence of ophthalmology consultations, 22 of 38 (58%) patients had regular ophthalmology consultations in March 2018, and 27 of 38 (71%) patients had consultations in the following year after receiving information from an HCUN. Only 1 of 22 patients (5%) who consulted the ophthalmologist in March 2018 used a DEN, but 19 of 27 patients (70%) used it the following year. Conclusion: In the future, the development and utilization of a new DEN that includes more detailed patient information, and the spread of self-care guidance to patients by multidisciplinary health care professionals, will increase the consultation rate of MHD patients in Japan and reduce the incidence and progression of ocular diseases in MHD patients.
RESUMEN
OBJECTIVE: Induction of hypertension by diabetic nephropathy (DN) may be dependent on increased renin secretion from juxtaglomerular cells (JGC). To reveal that the mechanisms of cell adhesion and cell motility associated with ß1-integrin phosphorylation contribute to pressure sensing in JGC, we tested the ß1-integrin phosphorylation levels in renal tissue and the relationship between ß1-integrin phosphorylation and the expression of renin. METHODS: The DN rat model was generated by intravenous injection of streptozotocin (STZ, 60 mg/kg body weight). Immunohistochemistry and an imaging analysis were performed to detect and evaluate the ß1-integrin phosphorylation levels in renal tissue. Quantitative real-time polymerase chain reaction was also performed to evaluate renin mRNA levels. RESULTS: We found that the serine-785 and threonine-788/789 sites of ß1-integrin are specifically phosphorylated in macula densa and JGC, respectively, and that changes in their expression during the progression of DN are associated with the production of renin. Phosphorylation of these ß1-integrins increased or decreased with changes of the renin expression during the progression of DN. In particular, phosphorylation of threonine-788/789 was negatively correlated with the expression of renin. CONCLUSION: These findings suggest that the phosphorylation of ß1-integrin may contribute to the regulatory mechanism of renin production in JGC.

BACKGROUND: Information about factors related to better adherence to continuous glucose monitoring (CGM) sensor adherence is quite limited. MATERIALS AND METHODS: Forty-six participants with type 1 diabetes using continuous subcutaneous insulin infusion (CSII) without CGM were recruited. The participants' characteristics and diabetes-related quality of life (QOL) were evaluated at baseline and one year after starting to use CGM. Participants wearing the sensor for ≥60% of the time were considered as adherent. RESULTS: The mean age of the 46 participants was 44.1 ± 15.0 years old and the mean glycohemoglobin (HbA1c) was 7.7 ± 1.0%; 60.9% of the participants were classified as adherent. The duration of using CSII was longer in the adherent group, and the degree of diabetic retinopathy was significantly different. There were no significant differences in age, frequency of self-monitoring of blood glucose, or Hypoglycemia Fear Survey (HFS-B for behavior, HFS-W for worry) score at baseline between the adherent and nonadherent groups. The Problem Areas in Diabetes (PAID) score at baseline was significantly higher and the total CSII-QOL score at baseline was significantly lower in the adherent group. The usage of dual-wave bolus was significantly increased in the adherent group (34.6%-61.5%, P = .016), but not in the nonadherent group (33.3%-33.3%, P > .999). The HbA1c level showed a significant improvement in the adherent group (7.8%-7.3%, P < .001), but not in the nonadherent group (7.5%-7.2%, P = .102). CONCLUSIONS: Higher adherence to CGM sensors may be associated with a heavier emotional burden of diabetes and a worse QOL in relation to CSII at baseline.

FreeStyle Libre has been approved for use in patients undergoing hemodialysis (HD) in Japan, unlike Europe and the United States; however, evidence regarding its accuracy in such patients is sparse. Forty-one participants with type 2 diabetes undergoing HD were recruited. The overall mean absolute relative difference and mean absolute difference were 23.4% and 33.9 mg/dL, respectively. Sensor glucose levels and capillary glucose levels were significantly correlated (r = 0.858, P < .01), although the sensor glucose levels were significantly lower than the capillary glucose levels. The accuracy of FreeStyle Libre in patients undergoing HD became deteriorated with the days of usage. The percentage of sensor results in Zones A and B in the consensus error grid analysis and in the Clarke error grid analysis were 99.7% and 99.0%, respectively. Its insufficient accuracy necessitates adjunct usage of FreeStyle Libre with self-monitoring of blood glucose in patients undergoing HD.

OBJECTIVE: The Japan Diabetes Society and the Japan Gerontological Society Collaborative Committee recently released guidelines for the management of elderly diabetes patients. In these guidelines, patients are classified into categories I-III depending on age, cognitive function, activities of daily living (ADL), and presence or absence of multiple functional impairments. The target control value of HbA1c is set for each category. Low (< 30 mL/min/1.73 m2) estimated glomerular filtration rate (eGFR) is an independent highrisk factor for severe hypoglycemia, yet it is not included in the categorization factors. We surveyed elderly diabetes patients with normal cognitive function and ADL (Category I) who were admitted to the emergency department with severe hypoglycemia, retrospectively studied eGFR at the onset of hypoglycemic episode, and checked whether the HbA1c levels matched the guidelines. METHODS: Among 129 diabetes patients aged ≥ 65 years admitted to the Tokai University hospital for hypoglycemic emergencies, 73 had normal cognitive function and ADL. HbA1c level and eGFR at the onset of hypoglycemic attack were obtained from the medical records of these subjects. RESULTS: All subjects were prescribed anti-diabetes agents with high-risk of severe hypoglycemia, including insulin. Sixty-one patients showed eGFR ≥ 30 mL/min/1.73 m2. Among them, 31 (50.8%) had HbA1c levels below the recommended range. Among 12 patients whose eGFR < 30 mL/min/1.73 m2, 6 (50%) had HbA1c levels below the recommended range. CONCLUSION: Even with normal cognitive function and ADL, eGFR < 30 mL/min/1.73 m2 a lone i s a s trong risk factor for hypoglycemia in elderly diabetes patients. We propose that the target control HbA1c level in elderly patients with eGFR < 30 mL/min/1.73 m2 should be 7.5-8.4 %, which is equivalent to that of category III patients.

OBJECTIVE: Patients with advanced diabetic nephropathy benefit from kidney transplantation. We report a patient who showed improved glycemic control after kidney transplantation followed by sensor-augmented pump (SAP) therapy. METHODS: The patient was a 67-year-old man on hemodialysis for diabetic nephropathy associated with slowly-progressive type 1 diabetes mellitus. He underwent living-donor kidney transplantation, followed by introduction of SAP therapy for strict glycemic control. RESULTS: SAP therapy improved glycated hemoglobin and glycated albumin levels from 7.8% and 24.2% to 7.0% and 19.2%, respectively, and reduced the frequency of hypoglycemic episodes. CONCLUSION: The case illustrates the usefulness of SAP therapy for post-kidney transplantation glycemic control.

A high intake of green leafy vegetables rich in antioxidative nutrients such as vitamin C and ß-carotene may protect against the risk of type 2 diabetes. Measurement of the circulating nutrient concentrations can indicate the nutrient status more directly, and vitamin C and carotenoids are recognized as good biomarkers for the intake of fruits and vegetables. The aim of this study was to investigate the relationships between serum antioxidative vitamin concentrations and type 2 diabetes in Japanese subjects. The study subjects comprised 506 men and 493 women who first underwent anti-aging health checks at Tokai University Tokyo Hospital. Serum concentration of vitamin (V) A, VC, α-tocoferol, ß-carotene, VB12, folate, ferritin and homocysteine, and fasting plasma glucose and HbA1c were used for analysis. Low levels of ß-carotene and VC were significantly associated with dysglycemia. Diabetic subjects showed significantly decreased ß-carotene and VC levels, and multivariate analyses suggested that low levels of ß-carotene and VC were factors related to diabetes. Low levels of ß-carotene and VC are significantly related to dysglycemia/type 2 diabetes, and encouraging people at a higher risk of diabetes to take more green vegetables may be useful as a dietary intervention to improve the antioxidative vitamin status and dysglycemia.
