RESUMO
AIM/INTRODUCTION: Insulin glargine U100/lixisenatide and insulin degludec/liraglutide are fixed-ratio combinations containing basal insulin and a glucagon-like peptide-1 receptor agonist capable of reducing both fasting and postprandial blood glucose levels with a single formulation. This study aimed to compare the time in range (TIR) and the time below range (TBR) level 1 using professional continuous glucose monitoring and to establish criteria for the differential use of the fixed-ratio combinations. MATERIALS AND METHODS: Thirty-six outpatients with type 2 diabetes mellitus (24 men and 12 women; average age, 62.1 years) were randomly assigned to the groups. At 0 and 18 weeks, a device was worn to compare the TIR and TBR level 1. The correlation between the C-peptide index at baseline and TIR at 18 weeks was assessed. RESULTS: The TIR and TBR level 1 showed no significant differences between the two groups. Both groups showed significant positive correlations between the C-peptide index and the TIR (P = 0.002, r = 0.679; P = 0.002, r = 0.681, respectively). The changes in glycemic variability, therapeutic indices, and body mass index were not significantly different among the groups (P > 0.05). The receiver operating curve analysis revealed that the cut-off values of the C-peptide index to achieve TIR of >70% at 18 weeks were 1.258 (sensitivity, 77.8%; specificity, 100%) and 1.099 (sensitivity, 57.1%; specificity, 90.9%) in the insulin glargine U100/lixisenatide and insulin degludec/liraglutide groups, respectively. CONCLUSIONS: A TIR of >70% was achieved for both fixed-ratio combinations without significant differences.

BACKGROUND: Arteriosclerosis and non-alcoholic fatty liver disease are major complications of diabetes mellitus. Hyperglycemia, insulin resistance, obesity, and metabolic syndrome are associated with the progression of these complications. Sodium-glucose transporter 2 inhibitors such as luseogliflozin are oral hypoglycemic agents that reduce glucose levels, induce loss of weight or body fat, and improve liver function. However, the effects of these agents on lipid profiles are unclear. Therefore, this study aimed to investigate these effects and their relationship with arteriosclerosis and non-alcoholic fatty liver disease. METHODS: This single-center, single-arm, open-labeled prospective study enrolled 25 outpatients with type 2 diabetes mellitus who visited Minami Osaka Hospital. Laboratory tests and body measurements were performed at weeks 0 and 24. Luseogliflozin was started at 2.5 mg/day after breakfast, and data from weeks 0 and 24 were evaluated. There were no changes in the doses of other antidiabetic and dyslipidemia drugs a month prior to or during the study. RESULTS: The patients showed significant reductions in the levels of triglycerides, remnant-like particle cholesterol, and triglyceride/high-density lipoprotein cholesterol ratio, along with significant increases in the levels of high-density lipoprotein cholesterol and apolipoprotein A-1. Alanine aminotransferase, γ-glutamyl transpeptidase, and the fatty liver index were significantly reduced. CONCLUSIONS: Luseogliflozin-induced changes in the lipid profile were related to the suppression or improvement of arteriosclerosis and liver function, respectively. Patients who received this drug also showed improvements in the levels of liver enzymes and reductions in the fatty liver index. Earlier use of luseogliflozin might prevent diabetic complications. Trial registration This study was registered in the University Hospital Medical Information Network Clinical Trial Registry (UMIN 000043595) on April 6th, 2021.
RESUMO
BACKGROUND: Absolute polycythemia can be primary or secondary. Erythropoietin-producing diseases (for example, hypoxia) are the major cause of secondary polycythemia. There are reports of polycythemia secondary to hydronephrosis. However, to our knowledge, there is no report on polycythemia secondary to hydronephrosis due to a urinary stone. Herein, we present a case of polycythemia with an elevated erythropoietin level in a patient with a urinary stone and unilateral hydronephrosis. CASE PRESENTATION: A 57-year-old Japanese man presented with polycythemia and an elevated erythropoietin level. Erythropoietin accumulation was not due to erythropoietin secretion by a tumor as no obvious lesions were detected on contrast-enhanced computed tomography. Abdominal ultrasonography revealed a stone in the left urinary tract and renal hydronephrosis, and 2 weeks later, the patient underwent transurethral ureterolithotripsy without complications. Blood tests 2 weeks after transurethral ureterolithotripsy showed that the erythropoietin level had declined. Hemoglobin concentration decreased from 20.8 mg/dL before and immediately after transurethral ureterolithotripsy to 15.8 mg/dL 3 months after transurethral ureterolithotripsy. This case was diagnosed as erythropoietin elevation due to unilateral hydronephrosis with a urinary stone, resulting in polycythemia. CONCLUSIONS: Hydronephrosis is a common disease but is not often associated with polycythemia. Further studies are required to elucidate the mechanism and implications of elevated erythropoietin production in hydronephrosis.

The patient was 82-year-old man with type 1 diabetes mellitus. He had been using insulin degludec (IDeg) and insulin glulisine (IGlu) for treatment. He was admitted to our hospital due to diabetic ketoacidosis. As he started eating after recovery, we restarted intensive insulin therapy for glycemic control. Although he had eaten almost whole meals, his fasting blood glucose was extremely low, and the existence of nocturnal hypoglycemia was apparent. We reduced the dose and changed the injection time (eveningâmorning) of IDeg. We also stopped the evening IGlu injection; however, his nocturnal hypoglycemia did not improve. We decided to switch IDeg to insulin glargine U300 and to attach an intermittently scanned continuous glucose monitor (isCGM). His nocturnal hypoglycemia improved three days later. Since he had chronic heart failure and premature ventricular contractions, we used a Holter electrocardiogram to investigate the difference in arrythmia during hypoglycemia and non-hypoglycemia. As a result, the number of premature ventricular contractions was apparently high during hypoglycemia. In the present case, which involved an elderly patient with type 1 diabetes mellitus, chronic heart failure and nocturnal hypoglycemia, switching IDeg to insulin glargine U300 improved nocturnal hypoglycemia. IDeg differs from insulin glargine U300 in that it has a fatty acid side chain, which leads IDeg to combine with serum albumin. We thought that the increased level of free fatty acid due to hypoglycemia was competing against albumin combined IDeg, which increased free IDeg, and as a result, encouraged hypoglycemia.

INTRODUCTION: We aimed to compare the efficacy of insulin degludec/insulin aspart (IDegAsp) and insulin degludec/liraglutide (IDegLira) in controlling glucose fluctuation and suppressing postprandial glucose levels using intermittently scanned continuous glucose monitoring. METHODS: Twenty-four patients with type 2 diabetes mellitus were randomly allocated to receive either IDegLira or IDegAsp followed by IDegAsp or IDegLira, respectively. A crossover study was conducted with intermittently scanned continuous glucose monitoring. We compared the postprandial blood glucose level, time in range, and time below range from a 3-day intermittently scanned continuous glucose monitoring period for each treatment group. RESULTS: The time in range was significantly higher in IDegLira than in IDegAsp. Postprandial glucose levels 90 and 120 min after breakfast and 60, 90, and 120 min after lunch were significantly lower for IDegLira than for IDegAsp. However, postprandial glucose levels 90 and 120 min after supper were significantly lower for IDegAsp than for IDegLira. There was no significant difference in the time below range between IDegLira and IDegAsp. CONCLUSION: IDegLira was more effective in treating type 2 diabetes mellitus than IDegAsp, as indicated by a higher time in range and lower postprandial glucose level at breakfast and lunch. This study was registered with the University Hospital Medical Information Network Clinical Trial Registry (UMIN 000039221).

BACKGROUND: Adaptive support ventilation (ASV) is a proposed treatment option for central sleep apnea (CSA). Although the effectiveness of ASV remains unclear, some studies have reported promising results regarding the use of ASV in patients with heart failure with preserved ejection fraction (HfpEF). To illustrate the importance of suspecting and diagnosing sleep-disordered breathing (SDB) in older adults unable to recognize symptoms, we discuss a case in which ASV was effective in a patient with CSA and HfpEF, based on changes in the Holter electrocardiogram (ECG). CASE PRESENTATION: An 82-year-old man presented to our hospital with vomiting on April 19, 2021. Approximately 10 years before admission, he was diagnosed with type 1 diabetes mellitus and recently required full support from his wife for daily activities due to cognitive dysfunction. Two days before admission, his wife was unable to administer insulin due to excessively high glucose levels, which were displayed as "high" on the patient's glucose meter; therefore, we diagnosed the patient with diabetic ketoacidosis. After recovery, we initiated intensive insulin therapy for glycemic control. However, the patient exhibited excessive daytime sleepiness, and numerous premature ventricular contractions were observed on his ECG monitor despite the absence of hypoglycemia. As we suspected sleep-disordered breathing (SDB), we performed portable polysomnography (PSG), which revealed CSA. PSG revealed a central type of apnea and hypopnea due to an apnea-hypopnea index of 37.6, which was > 5. Moreover, the patient had daytime sleepiness; thus, we diagnosed him with CSA. We performed ASV and observed its effect using portable PSG and Holter ECG. His episodes of apnea and hypopnea were resolved, and an apparent improvement was confirmed through Holter ECG. CONCLUSION: Medical staff should carefully monitor adult adults for signs of or risk factors for SDB to prevent serious complications. Future studies on ASV should focus on older patients with arrhythmia, as the prevalence of CSA may be underreported in this population and determine the effectiveness of ASV in patients with HfpEF, especially in older adults.

AIMS/INTRODUCTION: Multiple daily injection therapy for early glycemic control in patients with type 2 diabetes mellitus is associated with hypoglycemia and weight gain. This study aimed to compare the efficacy (time in range of glucose level 70-180 mg/dL), safety (time below range level 1 of glucose <70 mg/dL), glycemic variability changes, therapeutic indices, body mass index and titration periods between multiple daily injection and insulin glargine U100 and lixisenatide (iGlarLixi) combination (iGlarLixi + insulin glulisine; injected once daily [evenings]) therapies using intermittent continuous glucose monitoring. MATERIALS AND METHODS: A total of 40 hospitalized patients with type 2 diabetes were randomly assigned to the iGlarLixi + insulin glulisine group or the multiple daily injection group. An intermittent continuous glucose monitoring system was attached, and each injection was adjusted to achieve the target glucose level according to the respective titration algorithm. Times in and below the range were analyzed using data collected on days 11-13 of the intermittent continuous glucose monitoring. RESULTS: The time in range did not significantly differ between the groups. However, the time below range level 1 was lower in the iGlarLixi + insulin glulisine group (P = 0.047). The changes in glycemic variability, therapeutic indices and body mass index were not significantly different between the groups, although the titration period was significantly shorter in the iGlarLixi + insulin glulisine group (P = 0.033). CONCLUSIONS: iGlarLixi + insulin glulisine combination therapy is safe and equally efficacious as multiple daily injection therapy for glycemic control, while avoiding hypoglycemia risk and reducing the number of injections are required.

BACKGROUND AND OBJECTIVES: Vitamin D receptor activators and calcimimetics (calcium-sensing receptor agonists) are two major options for medical treatment of secondary hyperparathyroidism. A higher serum calcification propensity (a shorter T50 value) is a novel surrogate marker of calcification stress and mortality in patients with CKD. We tested a hypothesis that a calcimimetic agent etelcalcetide is more effective in increasing T50 value than a vitamin D receptor activator maxacalcitol. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: A randomized, multicenter, open-label, blinded end point trial with active control was conducted in patients with secondary hyperparathyroidism undergoing hemodialysis in Japan. Patients were randomly assigned to receive intravenous etelcalcetide 5 mg thrice weekly (etelcalcetide group) or intravenous maxacalcitol 5 or 10 µg thrice weekly (maxacalcitol group). The primary, secondary, and tertiary outcomes were changes in T50 value, handgrip strength, and score of the Dementia Assessment Sheet for Community-Based Integrated Care System from baseline to 12 months, respectively. RESULTS: In total, 425 patients from 23 dialysis centers were screened for eligibility, 326 patients were randomized (etelcalcetide, n=167; control, n=159), and 321 were included in the intention-to-treat analysis (median age, 66 years; 113 women [35%]). The median (interquartile range) of T50 value was changed from 116 minutes (interquartile range, 90-151) to 131 minutes (interquartile range, 102-176) in the maxacalcitol group, whereas it was changed from 123 minutes (interquartile range, 98-174) to 166 minutes (interquartile range, 127-218) in the etelcalcetide group. The increase in T50 value was significantly greater in the etelcalcetide group (difference in change, 20 minutes; 95% confidence interval, 7 to 34 minutes; P=0.004). No significant between-group difference was found in the change in handgrip strength or in the Dementia Assessment Sheet for Community-Based Integrated Care System score. CONCLUSIONS: Etelcalcetide was more effective in increasing T50 value than maxacalcitol among patients on hemodialysis with secondary hyperparathyroidism. There was no difference in handgrip strength or cognition between the two drugs. CLINICAL TRIAL REGISTRY NAME AND REGISTRATION NUMBER: VICTORY; UMIN000030636 and jRCTs051180156.

BACKGROUND: An association of higher levels of ß-hydroxybutyrate (ß-HB) in serum with greater mortality in hemodialysis (HD) patients has been reported. This study examined the significance of arterial ketone body ratio (AcAc/ß-HB), a relevant marker of energy state, in HD patients. METHODS: The levels of arterial AcAc and ß-HB, and AcAc/ß-HB ratio were determined in 49 HD patients just before undergoing an HD session. Additionally, changes in those levels during the session were examined to investigate their associations with clinical nutritional markers. RESULTS: Arterial ß-HB, but not AcAc, was significantly higher at the baseline in 25 patients with type 2 diabetes mellitus (T2DM) as compared to 24 non-DM patients, with a significant reduction in arterial AcAc/ß-HB ratio seen in those with DM. Although the arterial AcAc/ß-HB ratio before the HD session was significantly higher in the non-DM group, it did not differ significantly after the session between the groups, indicating a faster rate of ß-HB disappearance from circulation in non-DM HD patients during the interdialytic period. Multiple regression analysis, which included age, gender, presence/absence of DM, log HD duration, log ß-HB, and log AcAc/ß-HB ratio as independent variables, revealed an independent and significant association of log AcAc/ ß-HB ratio, but not log ß-HB, with serum albumin and uric acid. CONCLUSION: We found that a decreased AcAc/ß-HB ratio resulting from increased ß-HB, but not increased ß-HB itself, was a significant factor independently associated with decreased levels of serum albumin and uric acid, known to be related to higher mortality in HD patients. Furthermore, it is possible that higher mortality in DM HD patients can be explained by reduced arterial AcAc/ß-HB ratio.

INTRODUCTION: Sodium-glucose cotransporter 2 (SGLT2) inhibitors promote urinary glucose excretion. However, the differences in the effects of various SGLT2 inhibitors are unknown. We used flash glucose monitoring (FGM) to identify the differences between tofogliflozin and ipragliflozin in terms of efficacy in reducing glycemic variability and mitigate hypoglycemia risk. METHODS: In this crossover study, 24 patients with type-2 diabetes mellitus (T2DM) receiving insulin glargine U300 therapy were randomly allocated to tofogliflozin and ipragliflozin or ipragliflozin and tofogliflozin group. Glycemic variability and hypoglycemia were compared using to the 3-day FGM data per treatment period. RESULTS: Glucose level 2 h after each meal was significantly lower with tofogliflozin administration than with ipragliflozin administration. Time below the target glucose range after tofogliflozin administration was significantly lower than that after ipragliflozin administration (2.1% ± 4.4% vs. 8.7% ± 11.7%). The 24-h standard deviation of glucose level, mean amplitude of glycemic excursion, and mean percent time with nocturnal hypoglycemia after tofogliflozin administration were significantly lower than those after ipragliflozin administration. CONCLUSIONS: Tofogliflozin was more effective and safer than ipragliflozin in reducing glycemic variability and mitigating hypoglycemia risk in patients with T2DM treated with insulin glargine U300. TRIAL REGISTRATION: This trial was registered at the University Hospital Medical Information Network Clinical Trial Registry (no. UMIN000037158).
RESUMO
INTRODUCTION: Hypoglycemia resulting from insulin therapy for treatment of diabetes increases the risk of adverse cardiovascular events. Determining biomarkers that provide accurate estimation of hypoglycemia risk may allow for more accurate patient management and care. The purpose of this study was to determine the cutoff value of serum albumin (s-alb) that increases the risk of hypoglycemia in patients treated with insulin degludec. METHODS: This study used a crossover design and randomized 30 patients admitted for glycemic control to compare differences between insulin glargine 300 U/ml (Gla300) and degludec treatments. RESULTS: The cutoff value of s-alb associated with 24-h hypoglycemia and nocturnal hypoglycemia in patients treated with degludec was 3.8 g/dl. In patients with s-alb levels < 3.8 g/dl, mean percentages of time with hypoglycemia, clinically important hypoglycemia, and nocturnal hypoglycemia were significantly lower in those treated with Gla300 compared with patients treated with degludec. CONCLUSION: This study identified a cutoff value for s-alb levels that indicates risk of hypoglycemia in patients treated with degludec. Monitoring s-alb levels in patients treated with degludec will help to mitigate the risk of hypoglycemia. TRIAL REGISTRATION: University Hospital Medical Information Network (UMIN 000031044).
RESUMO
AIMS/INTRODUCTION: We compared the efficacy and safety of insulin degludec/aspart (IDegAsp) twice-daily injections with insulin glargine 300 U/mL and insulin glulisine basal-bolus therapy (Gla300/Glu) using insulin glargine 300 U/mL (Gla300) and insulin glulisine (Glu). MATERIALS AND METHODS: A total of 20 patients with type 2 diabetes mellitus were treated with IDegAsp twice-daily injections; achievement of target preprandial glucose concentration of 100-130 mg/dL at breakfast and supper was determined using a wearable flash glucose monitoring system. Patients were later switched to Gla300/Glu basal-bolus therapy before breakfast and before supper. Data were collected on days 2-4 and days 12-14 for each treatment period. The study's primary efficacy end-point was the mean percentage of time with a target glucose range of 70-180 mg/dL, and safety end-points were the mean percentage of time with hypoglycemia having glucose levels <70 mg/dL, clinically important hypoglycemia with glucose levels <54 mg/dL and nocturnal (00.00-06.00) hypoglycemia. RESULTS: Considering efficacy, the mean percentage of time for the target glucose range of IDegAsp was significantly lower than that of Gla300/Glu (73.1 [69.4-81.1] vs 84.2 [80.2-93.1], P = 0.001). Considering safety, the mean percentages of hypoglycemia (<70 mg/dL; 2.1 [0.0-9.4] vs 14.4 [4.4-22.3]), clinically important hypoglycemia (<54 mg/dL; 0.0 [0.0-0.2] vs 1.9 [0.0-5.6]) and nocturnal (00.00-06.00 hours) hypoglycemia (0.5 [0.0-5.9] vs 8.9 [3.1-11.8]) of Gla300/Glu were significantly lower than those of IDegAsp (P = 0.012, 0.036 and 0.007, respectively). CONCLUSIONS: When compared with the IDegAsp twice-daily injections, Gla300/Glu basal-bolus therapy might achieve more effective glycemic control without hypoglycemic risk.

AIMS/INTRODUCTION: Compared with glargine 100 U/mL (Gla100), glargine 300 U/mL (Gla300) and degludec (Deg) - the ultralong-acting insulins - reportedly have more stable effects and reduce the risk of hypoglycemia. Currently, they are considered to be the most useful basal insulins. The present study aimed to compare the efficacy and safety of Gla300 and Deg on glycemic control using continuous glucose monitoring. MATERIALS AND METHODS: In this single-center, open-label, parallel-group, two-period, cross-over study, 30 patients with type 2 diabetes were randomized to once-daily Gla300 followed by Deg with the same units (n = 15) or vice versa (n = 15). The primary end-points of this study were the mean percentage of time within the target glucose range of 70-180 mg/dL as efficacy and hypoglycemia of <70 mg/dL as safety indicators, as measured using continuous glucose monitoring during each treatment period. RESULTS: The mean percentage of time within the target glucose range was not different between Gla300 and Deg (77.8 ± 19.2 vs 76.9 ± 18.3%, P = 0.848). However, the mean percentage of time of hypoglycemia with Gla300 was significantly lower than that of Deg (1.3 ± 2.7 vs 5.5 ± 6.4%, P = 0.002). In the secondary safety end-points, the mean percentage of time of severe hypoglycemia (<54 mg/dL) or nocturnal hypoglycemia with Gla300 was also significantly lower than that of Deg. CONCLUSIONS: The present study showed the comparable efficacy of Gla300 and Deg on glycemic control; however, the risk of hypoglycemia was markedly lower for Gla300 than for Deg.

AIMS: Recent reports suggest that appropriate glycemic control without hypoglycemia could decrease mortality in patients with diabetes mellitus (DM) and end-stage renal disease (ESRD). However, an indication of oral anti-diabetic drugs is limited in this population. The aim of this study was to evaluate efficacy of teneligliptin, a novel DPP-4 inhibitor, by continuous glucose monitoring (CGM) in patients with type 2 DM (T2DM) on hemodialysis (HD). METHODS: This 4-week, open label, single arm, intervention trial included 10 diabetic patients undergoing HD and with glycated albumin (GA) level of ≥18.3%. Teneligliptin treatment was administered on days with HD sessions (HD day) and on days without HD sessions (NHD day); blood glucose values were measured by CGM. The primary endpoint was improvement of glycemic control evaluated by area under the curve (AUC). As secondary endpoints, changes in GA, HbA1c and fasting plasma glucose (FPG) were evaluated. RESULTS: Teneligliptin improved blood glucose AUC on both HD days (p=0.004), and NHD days (p=0.004). This was accompanied by a significant reduction in GA, HbA1c, and FPG, without severe hypoglycemia. CONCLUSIONS: Teneligliptin is one of the useful options for glycemic control in T2DM patients undergoing HD.

OBJECTIVE: Measurement of the peak systolic velocity (PSV) in the inferior thyroid artery (ITA) before withdrawal of an anti-thyroid drug (ATD) is useful for predicting relapse of Graves' disease (GD). We further investigated whether the ITA-PSV can be used for prediction of GD relapse after delivery in euthyroid women with GD who stopped ATD administration during mid- to late pregnancy. PATIENTS AND METHODS: ITA-PSV was monitored monthly for three months after delivery in 42 women with GD aged from 24 to 45 years old (mean+/-SE: 34.7+/-0.92 years old) who met the above criteria. To confirm the stability of the measurement, ITA-PSV was also measured monthly in 32 age-matched non-pregnant normal women and for three months after delivery in 10 age-matched women. RESULTS: ITA-PSV and thyroid volume were higher in women with GD immediately after delivery compared to normal women, but the levels of TSH receptor antibody (TRAb) and thyroid-stimulating antibody (TSAb) did not differ significantly between the two groups. Of the 42 patients, 23 had relapse of GD and the smoker/non-smoker ratio and thyroid volume in these patients immediately after delivery were significantly higher than those in the 19 patients who did not undergo relapse (10/23 vs. 0/19, p<0.0001; 24280.3+/-2280.9 vs. 19670.0+/-2103.7mm(3), p=0.046), while ITA-PSV, TRAb and TSAb did not differ between the two groups of patients. The ITA-PSV ratio was calculated by dividing each value in the follow-up period by that obtained immediately after delivery. A significant increase in the mean ITA-PSV ratio occurred at least one month before the time of relapse (1.00+/-0.00 at -3 months before relapse vs. 1.46+/-0.12 at -1 month, p=0.010; 1.00+/-0.00 at -3 months vs. 1.77+/-0.13 at the time of relapse, p=0.0048). In contrast, there were no significant changes in this ratio during the follow-up period in non-relapse patients.

OBJECTIVE: Subclinical hypothyroidism affects 5-15% of the general population, is especially prevalent in females, and may be associated with increased morbidity from cardiovascular disease, although it remains controversial. We recently reported a significant increase in the brachial-ankle pulse wave velocity (baPWV), a parameter of arterial stiffening and an independent predictor of cardiovascular events, in subclinical hypothyroidism without thyroiditis. The current study was performed to assess changes in baPWV in female subclinical hypothyroidism with autoimmune chronic thyroiditis (Hashimoto's disease) after restoration of normal thyroid function. METHODS: In a randomized placebo-controlled study, 95 female subclinical hypothyroid patients were monitored for changes in baPWV before and after levothyroxine (l-T(4)) replacement therapy. Changes in baPWV were also measured in 42 age-matched normal female subjects. RESULTS: The baseline baPWV values in patients with subclinical hypothyroidism were significantly higher than in normal subjects. With attainment of euthyroidism, baPWV showed a significant decrease from 1776.7+/-86.0 to 1674.3+/-79.2 cm/s (P=0.006) in patients treated with l-T(4), but the changes in baPWV and TSH were not correlated. The change in baPWV was significantly and negatively correlated with age and baseline pulse pressure, but multiple regression analysis revealed that these parameters failed to be associated with the change in baPWV. CONCLUSIONS: Sustained normalization of thyroid function during l-T(4) replacement therapy significantly decreases baPWV in female subclinical hypothyroid patients with autoimmune chronic thyroiditis, suggesting the improvement of arterial stiffening and, consequently, possible prevention of cardiovascular disease.

The diabetes is at great risk of the osteoporosis, and the bone fragility unrelated to bone density forms the pathological conditions peculiar to diabetes. The factor participating in diabetic osteoporosis has a state of insulin action deficiency, a hyperglycemic state, diabetic complications, and so on. An osteoblastic cell function is deteriorated and the number of that is decreased by the absolute and relative insulin deficiency, and sustained hyperglycemia also decreases an osteoblastic cell function still more. Furthermore, the osteoclast-related bone resorption is also promoted through sorbitol accumulation in the cell by the hyperglycemia state. The expression of transcription factors regulating osteoblastic cell differentiation is restrained, and the apoptosis of those cells is promoted. As a result, osteoplasty is obstructed. In the bone, AGEs (advanced glycation endproducts) is produced in excess, and bone fragility is promoted by the ratio of the AGEs bridging with the collagen rising. The complications of diabetes, such as visual disorder and the neuropathy, raise the risk of the fall in the diabetic osteoporosis patient, therefore, they will have more chance of fractures.

Tartrate-resistant acid phosphatase (TRAP) 5b is a new marker of bone resorption that is unaffected by renal dysfunction. The significance of TRAP5b was assessed in hemodialysis (HD) patients. Serum concentrations of TRAP5b and cross-linked N-telopeptide of type I collagen (NTX) were determined as bone resorption markers, and those of bone alkaline phosphatase (BAP) and intact osteocalcin (OC) were measured as bone formation markers in 58 HD patients. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry twice in the distal third of the radius, with a 2-year interval between measurements. Serum TRAP5b correlated significantly with BAP, intact OC, intact parathyroid hormone (PTH), and especially serum NTX. TRAP5b, NTX, BAP, and intact OC all correlated significantly with BMD at the time of the second measurement; and TRAP5b, NTX, and intact OC, but not BAP and intact PTH, correlated significantly with the annual change in BMD during the 2-year period. Among the bone markers, patients in the highest tertile for serum TRAP5b and intact OC showed the fastest rate of cortical bone loss. The sensitivity and specificity for detection of rapid bone loss were 57.9% and 76.9%, respectively, for serum TRAP5b. Measurement of serum TRAP5b, as well as intact OC, may be a clinically relevant assay for estimation of bone metabolic status in HD patients, although serum intact OC accumulates in uremic serum.

OBJECTIVE: We recently reported that glycated albumin (GA) is a better indicator of glycaemic control compared with glycated haemoglobin (HbA1c) in haemodialysis (HD) patients with type 2 diabetes. As poor glycaemic control is considered an independent risk factor for atherosclerosis in diabetes, the relationship between GA, HbA1c and arterial stiffening was examined in HD patients with type 2 diabetes. PATIENTS AND METHODS: The present study comprised 134 HD patients with type 2 diabetes, and 158 patients without diabetes. Brachial-ankle pulse wave velocity (baPWV) was measured in all patients using a waveform analyser. RESULTS: The mean plasma glucose (PG), GA and HbA1c levels were 7.49 +/- 2.28 mmol/l, 20.8 +/- 5.57% and 5.62 +/- 1.26%, respectively, in HD patients with diabetes (n = 134), which were significantly greater than the respective values of 5.77 +/- 1.89 mmol/l, 15.6 +/- 2.34% and 4.98 +/- 0.80% in those without diabetes (n = 158) (P < 0.0001). BaPWV was 21.69 +/- 6.90 m/s in HD patients with diabetes, which was significantly greater than the value of 18.74 +/- 4.89 m/s in those without diabetes (P < 0.0001). When the analysis was performed in a combined population of those patients with and without diabetes, the mean PG (r = 0.155, P < 0.05) and GA (r = 0.117, P < 0.05), but not HbA1c (r = 0.092, P = 0.125), exhibited significant correlations with baPWV. Multivariate regression analysis, which included age, gender, mean blood pressure, and serum levels of albumin, creatinine and LDL cholesterol, to evaluate the independent association of each marker for glycaemic control with baPWV values in HD patients demonstrated that GA, but not HbA1c or PG, was an independent factor that was significantly associated in a positive manner with baPWV in HD patients. CONCLUSION: It was suggested that poor glycaemic control, as reflected by increased GA values, might be associated with increased arterial stiffening in HD patients.
