Two cases with Hb Andrew-Minneapolis showing high or low-normal HbA1c levels depending on the measurement method.

We experienced two cases of Hb Andrew-Minneapolis with high or low-normal HbA1c levels depending on the measurement method. Case 1 was a 25-year-old male, and case 2 was a 32-year-old pregnant woman. Both cases showed normal glucose tolerance levels and glycated albumin within the reference range.

Neuropsychiatric Immune-related Adverse Events Induced by Pembrolizumab in a Patient with Lung Adenocarcinoma and Systemic Lupus Erythematosus.

The patient was a 73-year-old woman with lung adenocarcinoma and systemic lupus erythematosus (SLE) who was treated with pembrolizumab. After six cycles of pembrolizumab, she developed symptoms suggestive of neuropsychiatric SLE, such as resting tremor, confusional state, depression, mood disorder, and anxiety disorder. In addition, her cerebrospinal fluid level of interleukin-6 was elevated.

A case of monoclonal gammopathy of undetermined significance with abnormal low levels of plasma glycated albumin by M protein.

Background: It is known that an immunoglobulin abnormality affects various clinical laboratory measurements and leads to abnormal values. We experienced a case of monoclonal gammopathy of undetermined significance (MGUS) showing a falsely low plasma glycated albumin (GA) level.

Case Report: The patient was a 75-y-old male who visited our hospital for thrombocytosis identified during a medical checkup.

Factors correlated with serum insulin-like growth factor-I levels in health check-up subjects.

Background: Most of circulating IGF-I is derived from the liver and circulating IGF-I levels are decreased in several pathological conditions, such as liver cirrhosis, uncontrolled diabetes, renal failure, and malnutrition. However, it has not fully been elucidated which factors modify IGF-I level in a physiological condition.

Objective: To identify the factors which are associated with circulating IGF-I levels.

Glycemic control indicator levels at diagnosis of neonatal diabetes mellitus: Comparison with other types of insulin-dependent diabetes mellitus.

Background: Neonatal diabetes mellitus (NDM) is a monogenic insulin-dependent diabetes that develops within 6 months of age. The progression of hyperglycemia until diagnosis is unknown. Glycemic control indicators at diagnosis are useful to estimate the extent and duration of hyperglycemia.

Incompatibility between fasting and postprandial plasma glucose in patients with Cushing's syndrome.

It is shown that glucocorticoids have discordant effects on plasma glucose concentration through their effects on hepatic glycogen deposition, gluconeogenesis and peripheral insulin resistance. Cushing's syndrome caused by cortisol overproduction is frequently accompanied with diabetes mellitus, but fasting plasma glucose (FPG) and post-glucose load plasma glucose levels are not examined in patients with Cushing's syndrome. The aim of this study was to investigate FPG, HbA1c and oral glucose tolerance test (OGTT) 2-h PG and their relationship in patients with Cushing's syndrome, in comparison with control subjects.

The Glycated Albumin (GA) to HbA1c Ratio Reflects Shorter-Term Glycemic Control than GA: Analysis of Patients with Fulminant Type 1 Diabetes.

Background: Glycated albumin (GA) reflects shorter-term glycemic control than HbA1c. We have reported that HbA1c is paradoxically increased in diabetic patients whose glycemic control deteriorated before ameliorating. In this study, we analyzed paradoxical increases of glycemic control indicators after treatment in patients with fulminant type 1 diabetes (FT1D).

Diagnosis and treatment of adrenal insufficiency including adrenal crisis: a Japan Endocrine Society clinical practice guideline [Opinion].

This clinical practice guideline of the diagnosis and treatment of adrenal insufficiency (AI) including adrenal crisis was produced on behalf of the Japan Endocrine Society. This evidence-based guideline was developed by a committee including all authors, and was reviewed by a subcommittee of the Japan Endocrine Society. The Japanese version has already been published, and the essential points have been summarized in this English language version.

Clinical and endocrinological characteristics of adrenal incidentaloma in Osaka region, Japan.

The aim of this study was to investigate the clinical and endocrinological characteristics of adrenal incidentalomas in Osaka region, Japan. The study was a multicenter retrospective analysis of 150 patients with adrenal incidentalomas who underwent radiographic and endocrine evaluations between 2005 and 2013. Most adrenal incidentalomas were discovered by computed tomography (77.

Is glycated albumin useful for differential diagnosis between fulminant type 1 diabetes mellitus and acute-onset autoimmune type 1 diabetes mellitus?

Background: Markedly elevated plasma glucose and relatively low HbA1c compared to plasma glucose is one diagnostic criterion for fulminant type 1 diabetes mellitus (FT1DM). Glycated albumin (GA) is a glycemic control marker that reflects glycemic control in shorter period than HbA1c. This study investigated whether GA is useful for differential diagnosis between FT1DM and acute-onset autoimmune type 1 diabetes mellitus (T1ADM) or not.

Patients who showed paradoxical increase in HbA1c levels after intensification of diabetes treatment.

Objectives: When diabetes treatment is started, added, or changed (intensification of treatment) in patients with poor glycemic control, GA (glycated albumin) decreases within a few weeks, while HbA1c increases in some patients, resulting in a discrepancy between changes in GA and HbA1c. In the present study, we investigated the pathophysiology of such discrepancies.

Design And Methods: Four diabetic patients with poor glycemic control in whom GA showed a decrease while HbA1c showed an increase at a few weeks after intensification of treatment, resulting in a discrepancy between the time course of HbA1c and that of GA, were studied.

Low serum level of high-sensitivity C-reactive protein in a Japanese patient with maturity-onset diabetes of the young type 3 (MODY3).

High-sensitivity C-reactive protein (hs-CRP) levels in European populations are lower in patients with maturity-onset diabetes of the young type 3 (MODY3) than in those with type 2 diabetes. hs-CRP levels have been suggested to be useful for discriminating MODY3 from type 2 diabetes. As hs-CRP levels are influenced by various factors including race and body mass index, it is worthwhile to examine whether hs-CRP can serve as a biomarker for MODY3 in Japanese.

Serum albumin-adjusted glycated albumin is an adequate indicator of glycemic control in patients with Cushing's syndrome.

Objectives: We recently reported that glycated albumin (GA) in patients with Cushing's syndrome is low. In the present study, we examined whether serum albumin (SA)-adjusted GA (SAaGA) is an adequate indicator of glycemic control in patients with Cushing's syndrome.

Design And Methods: We studied 26 patients with Cushing's syndrome (13 patients without diabetes and 13 patients with diabetes).

Glycated albumin is not significantly correlated with body mass index in patients with acute-onset type 1 diabetes.

Background: No previous reports have clarified the relationship between glycated albumin (GA) and BMI in patients with acute-onset type 1 diabetes.

Methods: We conducted a cross-sectional study evaluating the correlation between GA and BMI in 209 patients with acute-onset type 1 diabetes and in 159 patients with type 2 diabetes who were designated as the control group. The correlation between fasting serum C-peptide immunoreactivity (CPR) and GA or BMI was also evaluated to clarify the impact of insulin secretion capacity on the relationship between GA and BMI.

Body mass index negatively regulates glycated albumin through insulin secretion in patients with type 2 diabetes mellitus.

Background: Glycated albumin (GA) is known to be negatively regulated by body mass index (BMI) in non-diabetic subjects and patients with type 2 diabetes mellitus (T2DM). In non-diabetic subjects, a mechanism has been proposed in which chronic inflammation associated with obesity increases albumin metabolism and negatively regulates GA levels. However, whether this same mechanism exists in T2DM is unclear.

Metformin decreases glycated albumin to glycated haemoglobin ratio in patients with newly diagnosed type 2 diabetes.

Background: To know whether metformin improves postprandial hyperglycaemia, we examined the effect of metformin on the glycated albumin (GA) to glycated haemoglobin (HbA1c) ratio (GA/HbA1c ratio) in patients with newly diagnosed type 2 diabetes.

Methods: Metformin and lifestyle interventions were initiated in 18 patients with newly diagnosed type 2 diabetes. Metformin was titrated to 1500 mg/day or maximum-tolerated dose.

Calculation of HbA1c and glycated albumin from serially measured self-monitored blood glucose in patients with type 1 diabetes mellitus.

Background: Both HbA1c and glycated albumin (GA) values are influenced by weighted mean of preceding blood glucose levels depending on each half-life. Based on this principle, we developed formulas for calculation of HbA1c and GA using data from self-monitored blood glucose (SMBG). We also calculated HbA1c and GA in diabetic patients using the developed formulas.

Glycated albumin is set lower in relation to plasma glucose levels in patients with Cushing's syndrome.

Background: Glycated albumin (GA) is an indicator of glycemic control, which has some specific characters in comparison with HbA1c. Since glucocorticoids (GC) promote protein catabolism including serum albumin, GC excess state would influence GA levels. We therefore investigated GA levels in patients with Cushing's syndrome.

Study on the mechanism causing elevation of serum CA19-9 levels in diabetic patients.

Serum CA19-9 levels are often elevated in diabetic patients. To elucidate this mechanism, we investigated the metabolism of CA19-9 in diabetic patients without obvious cancer. Study 1 included 119 patients in whom HbA1c, glycated albumin (GA) and CA19-9 were measured at the time of hospital admission.

The glycated albumin to HbA1c ratio is elevated in patients with fulminant type 1 diabetes mellitus with onset during pregnancy.

Fulminant type 1 diabetes mellitus (FT1DM) develops as a result of very rapid and almost complete destruction of pancreatic β cell. The most common form of type 1 diabetes mellitus with onset during pregnancy has been shown to be FT1DM at least in Japan. We previously reported that the ratio of glycated albumin (GA) to HbA1c (GA/HbA1c ratio) is elevated in FT1DM patients at the diagnosis.

The fractional exhaled nitric oxide and serum high sensitivity C-reactive protein levels in cough variant asthma and typical bronchial asthma.

Background: Fractional exhaled nitric oxide (FeNO) is known to be a good marker of airway eosinophilic inflammation in bronchial asthma. Recently, serum high sensitivity C-reactive protein (hs-CRP) has been shown to be also useful to detect the airway inflammation.

Methods: Newly diagnosed 90 cough variant asthma and 92 bronchial asthma patients were enrolled.

Comparison of annual variability in HbA1c and glycated albumin in patients with type 1 vs. type 2 diabetes mellitus.

Objective: It has been suggested that plasma glucose (PG) levels per se and long-term variations in PG levels are associated with diabetic vascular complications. Glycated albumin (GA) reflects shorter-term glycemic control, as well as postprandial PG levels, as compared to HbA1c. In this study, we hypothesized that GA more strongly reflects long-term variations in PG levels than HbA1c, and compared the variability of HbA1c and that of GA in patients with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM).

Classification of variant forms of haemoglobin according to the ratio of glycated haemoglobin to glycated albumin.

Background: Asymptomatic variant haemoglobin is increasingly being found in the measurement of glycated haemoglobin (HbA(1c)) for the management of diabetes mellitus. We compared the HbA(1c) concentrations measured by high-performance liquid chromatography (HPLC) and immunoassay and glycated albumin (GA) concentrations and calculated the respective ratios in order to classify the variant haemoglobin.

Methods: Twenty different haemoglobin variants from 43 subjects were identified by mass spectrometry and DNA analysis.

The glycated albumin to glycated haemoglobin ratio increases along with the fibrosis stage in non-alcoholic steatohepatitis.

Background: We previously reported that the indicator of glycaemic control, glycated albumin (GA) levels, are low in relation to glycaemia in patients with high alanine aminotransferase (ALT) levels in non-alcoholic fatty liver disease because of chronic inflammation, and that the GA/glycated haemoglobin ratio (G/H ratio) is inversely correlated with hepatic function in patients with chronic liver disease. The severity of liver fibrosis is known to be a good indicator for surveillance, and for determining the prognosis and optimal treatment of non-alcoholic steatohepatitis (NASH). In this study, we aimed to investigate the clinical usefulness of measuring the G/H ratio for predicting the severity of liver fibrosis in patients with NASH.
