Comprehensive immunophenotypic analysis reveals the pathological involvement of Th17 cells in Graves' disease.

Graves' disease (GD) is an organ-specific autoimmune disease, but there are a few studies that have evaluated how immunophenotypes are related to clinical symptoms and intractable pathology, or the effects of treatment on immunophenotypes. We performed peripheral blood immunophenotyping in GD. We assessed the proportion of functional subsets of T helper cells (such as Th1, Th17, Treg and Tfh cells), B cells (Naïve, IgM memory, Class-switched, IgDCD27 double negative and Plasmablasts cells), Monocytes, Dendritic cells and NK cells, and evaluated the relationship of immunophenotypes with clinical indices, disease activity, risk of relapse, and changes in immunophenotypes after treatment with antithyroid drugs.

Safety monitoring of COVID-19 vaccines in Japan.

The assessment of the efficacy and safety of coronavirus disease 2019 (COVID-19) vaccines in actual practice is extremely important, and monitoring efforts are being implemented worldwide. In Japan, a joint council in the Ministry of Health, Labour and Welfare is held every two to three weeks to summarise information on the adverse events following COVID-19 vaccination, with careful assessment of individual case safety reports and comparison with background incidence rates. In 2021, the joint council mainly reviewed anaphylaxis, death, myocarditis/pericarditis, and thrombosis with thrombocytopenia syndrome.

Hypoglycemia induces vascular endothelial dysfunction in subjects with normal glucose tolerance.

This prospective study determined the effects of hypoglycemic stimulation on vascular endothelial function in non-diabetic patients using reactive hyperemia peripheral arterial tonometry (RH-PAT). The study included non-diabetic patients who were hospitalized for an insulin tolerance test (ITT) for the diagnosis of hypoadrenocorticism or hypopituitarism. Vascular endothelial function was assessed using the reactive hyperemia index (RHI) measured by the RH-PAT.

Human dendritic cell-derived osteoclasts with high bone resorption capacity and T cell stimulation ability.

Osteoclasts are typically differentiated from monocytes (Mo-OC). A subset of osteoclasts (DC-OC) that are differentiated from dendritic cells (DC) has been reported in the arthritic mice model. However, little information is available on DC-OC in humans.

Response of thyrotropin-secreting pituitary tumors to preoperative lanreotide therapy. Report of two cases.

Case 1 was a 51-year-old man diagnosed with thyrotropin (TSH)-secreting pituitary tumor. The octreotide loading test showed suppression of TSH secretion. Treatment with lanreotide preoperatively at 90 mg/month resulted in normalization of thyroid function.

Efficacy and Safety of Tofogliflozin on 24-h Glucose Profile Based on Continuous Glucose Monitoring: Crossover Study of Sodium-Glucose Cotransporter 2 Inhibitor.

To compare the impact of two sodium-glucose cotransporter 2 (SGLT2) inhibitors, tofogliflozin and ipragliflozin, on hypoglycemia in patients with type 2 diabetes mellitus (T2DM), treated with sulfonylureas. Thirty patients with T2DM were allocated to treatment with either 20 mg/day tofogliflozin or 50 mg/day ipragliflozin and underwent continuous glucose monitoring (CGM) for 5 days at three times in a crossover manner. The percent time spent at glucose <70 mg/dL per 24 h was 0.

A Study of the Vascular Endothelial Function in Patients with Type 2 Diabetes Mellitus and Rheumatoid Arthritis.

Objective Type 2 diabetes mellitus (T2DM) and rheumatoid arthritis (RA) are both complicated by arteriosclerosis, resulting in increased rates of cardiovascular events. No previous studies have compared the index between RA and T2DM. We assessed the vascular endothelial function in early-stage arteriosclerosis for each disease to determine the influential factors and compared the extent to which these two diseases cause vascular endothelial dysfunction.

Hypoglycemia in blood glucose level in type 2 diabetic Japanese patients by continuous glucose monitoring.

Background: Hypoglycemia is associated with cardiovascular diseases, increased risk of death. Therefore, it is important to avoid hypoglycemia. The aim of this study was to characterize hypoglycemia according to glycated hemoglobin (HbA1c) level and determine the contributing factors in type 2 diabetes mellitus (T2DM), using continuous glucose monitoring (CGM).

Glycemic Profiling in Patients with Drug-Naïve Type 2 Diabetes by Continuous Glucose Monitoring.

The purpose of this study was to determine the glycemic profiles of drug-naïve type 2 diabetes patients according to hemoglobin A1c (HbA1c) level using continuous glucose monitoring. We aimed to clarify factors associated with HbA1c and average blood glucose level. Patients were divided into three groups according to their HbA1c level (< 7.

Association Between Diabetic Microangiopathies and Glycemic Variability Assessed by Continuous Glucose Monitoring.

The aim of this retrospective study was to elucidate the association between glucose profile using the continuous glucose monitoring system (CGMS) and microvascular complications in patients with type 2 diabetes mellitus (T2DM). The subjects were 160 inpatients with T2DM. The mean blood glucose (MBG) level, percentage of time in a 24-hour period spent with blood glucose level higher than 180 mg/dl (time at >180 mg/dl), standard deviation (SD), and mean amplitude of glycemic excursions (MAGE) were measured continuously over 48 hours using the CGMS.

Clinical Features of Patients with Basedow's Disease and High Serum IgG4 Levels.

Objective IgG4-related disease is a recently characterized condition presenting with high blood IgG4 levels, swelling of organs, and hypertrophic lesions. This disease is associated with thyroid disease, Hashimoto's disease, and Riedel's thyroiditis. However, there is little information on the association between IgG4-related disease and Basedow's disease.

Twenty-four-hour variations in blood glucose level in Japanese type 2 diabetes patients based on continuous glucose monitoring.

Aims/introduction: High fluctuations in blood glucose are associated with various complications. The correlation between glycated hemoglobin (HbA1c) level and fluctuations in blood glucose level has not been studied in Japanese patients with type 2 diabetes. In the present study, blood glucose profile stratified by HbA1c level was evaluated by continuous glucose monitoring (CGM) in Japanese type 2 diabetes patients.

Comparative analysis of the effects of alogliptin and vildagliptin on glucose metabolism in type 2 diabetes mellitus.

The aim of this 24-week, prospective randomized open-label study was to compare the effects of alogliptin and vildagliptin on glucose control, renal function, and lipid metabolism. In Study 1, DPP-4 inhibitor-naive type 2 diabetes (T2DM) were randomly assigned to alogliptin 25 mg/day or vildagliptin 50 mg twice daily. In Study 2, T2DM on treatment with 50 mg/day sitagliptin were switched to either 25 mg/day alogliptin or 50 mg twice daily vildagliptin.

Factors influencing inter-day glycemic variability in diabetic outpatients receiving insulin therapy.

Introduction: The aim of the present study was to determine the actual state of inter-day glycemic variability and identify the factors that affect glycemic variability in diabetic outpatients on insulin therapy.

Materials And Methods: The participants were 45 outpatients with diabetes mellitus receiving insulin therapy. The mean plasma glucose (MPG) levels, intra-day glycemic variability (expressed by standard deviation and mean amplitude of glucose excursion) and inter-day glycemic variability (expressed by mean of daily differences [MODD] in blood glucose levels) were measured continuously over 7 days with iPro2 .

Prednisolone Dosing Regimen for Treatment of Subacute Thyroiditis.

The rate of recurrence of subacute thyroiditis (SAT) during prednisolone (PSL) therapy is approximately 10 to 20%. However, there is little or no information on the time period to relapse following administration of a tapered dose of PSL and the factors associated with such relapse. The aim of this study was to determine the correlation between SAT recurrence and PSL tapering regimen used in the treatment of SAT.

[Apathetic hyperthyroidism with heart failure in an elderly patient with Plummer's disease].

We report a case of apathetic hyperthyroidism associated with unrecognized slowly growing functional thyroid adenoma (Plummer's disease), atrial fibrillation and heart failure. An 81-year-old woman with worsening thyroid dysfunction was admitted to our hospital for the treatment of heart failure. The patient had developed heart failure associated with chronic atrial fibrillation at 76 years of age, and one year later was found to have asymptomatic hyperthyroidism.

Induction of thyroid remission using rituximab in a patient with type 3 autoimmune polyglandular syndrome including Graves' disease and type 1 diabetes mellitus: a case report.

Rituximab (RTX) is a monoclonal antibody that targets the B-cell-specific CD20 antigen. Recent reports indicate that RTX is effective against type 1 diabetes mellitus (T1DM) and hematologic as well as autoimmune diseases. Other studies have indicated that RTX therapy leads to the remission of recurrent or active Graves' disease (GD).

Glucose variability before and after treatment of a patient with Graves' disease complicated by diabetes mellitus: assessment by continuous glucose monitoring.

A 48-year-old woman was diagnosed and treated for Graves' disease (GD) in 1999 but she discontinued treatment at her own discretion. In 2011, she was admitted to a local hospital for management of thyrotoxic crisis. Treatment with propylthiouracil, iodide potassium (KI), and prednisolone (PSL) was started, which resulted in improvement of the general condition.

Efficacy of combination of Ezetimibe 10 mg and rosuvastatin 2.5 mg versus rosuvastatin 5 mg monotherapy for hypercholesterolemia in patients with type 2 diabetes.

Background: Statins are used to treat hypercholesterolemia in patients with type 2 diabetes mellitus, but many of these patients fail to achieve the target LDL-C level. Recent reports have suggested that a synergistic effect can be obtained by concomitant administration of the cholesterol absorption inhibitor ezetimibe and a statin. However, in patients with type 2 diabetes who are already being treated with satins, it remains unclear whether it is more effective to add ezetimibe or to increase the statin dose.
