Abstract
Coronavirus disease 2019 (COVID-19) due to a severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection can include various systemic organ disorders including endocrinopathies and neurological manifestations. We report the case of a 65-year-old Japanese man who developed isolated adrenocorticotropic hormone (ACTH) deficiency and encephalopathy following SARS-CoV-2 infection. Two weeks after his COVID-19 diagnosis, he was emergently admitted to our hospital because of subacute-onset delirium. On admission, he presented hyponatremia (128 mEq/L) and secondary adrenal insufficiency (ACTH <1.5 pg/mL, cortisol 0.53 μg/dL). Brain imaging and laboratory examinations including SARS-CoV-2 polymerase chain reaction testing in the cerebrospinal fluid revealed no abnormalities. His consciousness level worsened despite the amelioration of hyponatremia by intravenous hydrocortisone (100 mg/day), but his neurological presentations completely resolved after three consecutive days of high-dose (400 mg/day) hydrocortisone. His encephalopathy did not deteriorate during hydrocortisone tapering. He continued 15 mg/day hydrocortisone after discharge. His encephalopathy might have developed via a disturbance of the autoimmune system, or a metabolic effect associated with adrenal insufficiency, although the time lag between the hyponatremia's improvement and the patient's neurological response to the steroid was incompatible with common cases of delirium concurrent with adrenal insufficiency. At 13 months after his hospitalization, the patient's neurological symptoms have not recurred and he has no endocrinological dysfunctions other than the remaining ACTH deficiency. A thorough consideration of the immunological and metabolic characteristics of SARS-CoV-2 is advisable when clinicians treat patients during and even after their COVID-19 disease period.

Abstract
Objective Maternally inherited diabetes and deafness (MIDD) is characterized by progressive insulin secretory disorder caused by impairment of mitochondrial adenosine triphosphate (ATP) production in pancreatic beta-cells. The amino acid 5-aminolevulinic acid (5-ALA) is the first heme biosynthetic precursor and the administration of 5-ALA combined with sodium ferrous citrate (SFC) enhance heme production, leading to improvement of mitochondrial function and ATP production. Several studies showed that the treatment with 5-ALA/SFC improved glycemic tolerance in both patients with prediabetes and those with type 2 diabetes. However, no previous studies investigated the efficacy of 5-ALA in patients with MIDD. We carried out the pilot trial to investigate whether the administration of 5-ALA/SFC can improve insulin secretion and glucose tolerance in patients with MIDD. Methods We enrolled five patients with MIDD receiving multiple daily injections of insulin. The patients were administered 5-ALA/SFC 100 mg twice a day (200 mg per day) for 24 weeks as adjunctive to insulin treatment. The patients underwent a 75-g oral glucose tolerance test (OGTT) twice before (1 st -OGTT) and 24 weeks after the initiation of 5-ALA/SFC (2 nd -OGTT). We measured levels of plasma glucose, insulin, and glucagon at fasting (0 min), and 30, 60 and 120 min after glucose load (Study protocol: Nakamura Y et al. Medicine (Baltimore). 2021; 100: e25100). Results The mean levels of HbA1c tended to decrease from 8.3% to 7.9% (p = 0.36) even though total insulin doses had not changed during the 24 weeks of 5-ALA/SFC administration. In the 2nd -OGTT comparing to the 1 st -OGTT, four of the five patients showed a tendency of improvement in glucose levels with a certain degree of insulin increase, but one patient did not show any improvement. The means of area under the curve (AUC) of serum insulin from fasting to 120 min during 2nd -OGTT was 30% larger but not significant compared to that during 1st -OGTT (p = 0. 077). The late phase of glucose excursion during OGTT determined by AUC of plasma glucose from 60 to120 min during 2nd -OGTT showed 10% reduction compared to that during 1st -OGTT (p = 0. 041). The glucagon levels during OGTT were comparable between before and after 5-ALA/SFC administration. The indexes of insulin sensitivity calculated by the homeostasis model assessment of insulin resistance or Matsuda index were not significantly changed between before and after 5-ALA/SFC administration. None of the patients experienced any adverse events during the study. Conclusions The administration of 5-ALA/SFC as adjunctive to insulin therapy might be a novel effective treatment for MIDD that improves insulin secretion via amelioration of mitochondrial function.

Abstract
Gestational diabetes mellitus (GDM) is known to be a significant risk factor for the future development of type 2 diabetes. Here, we investigated whether a precise evaluation of β- and α-cell functions helps to identify women at high risk of developing glucose intolerance after GDM. Fifty-six women with GDM underwent a 75-g oral glucose tolerance test (OGTT) at early (6-12 weeks) postpartum. We measured their concentrations of glucose, insulin, proinsulin and glucagon at fasting and 30, 60 and 120 min. At 1-year post-delivery, we classified the women into a normal glucose tolerance (NGT) group or an impaired glucose tolerance (IGT)/diabetes mellitus (DM) group. Forty-three of the 56 women completed the study. At 1-year post-delivery, 17 women had developed IGT/DM and 26 women showed NGT. In the early-postpartum OGTTs, the IGT/DM group showed a lower insulinogenic index, a less glucagon suppression evaluated by the change from fasting to 30 min (ΔGlucagon 30 min), and a higher glucagon-to-insulin ratio at 30 min compared to the NGT group. There were no significant between-group differences in proinsulin levels or proinsulin-to-insulin ratios. Insulinogenic index <0.6 and ΔGlucagon 30 min >0 pg/mL were identified as predictors for the development of IGT/DM after GDM, independent of age, body mass index, and lactation intensity. These results suggest that the bihormonal disorder of insulin and glucagon causes the postpartum development of glucose intolerance. The measurement of plasma insulin and glucagon during the initial OGTT at early postpartum period can help to make optimal decisions regarding the postpartum management of women with GDM.

Abstract
BACKGROUND Mitochondrial diabetes mellitus (MDM) is characterized by maternal inheritance, progressive neurosensory deafness, insulin secretory disorder, and progressive microvascular complications. Mitochondria are critical organelles that provide energy in the form of adenosine triphosphate (ATP). An impairment of ATP production in pancreatic β cells is regarded as the main cause of the insulin secretory disorder in patients with MDM, and these patients require insulin replacement therapy early after the diagnosis. The amino acid 5-aminolevulinic acid (5-ALA), a precursor of heme metabolites, is a non-proteinogenic δ amino acid synthesized in mitochondria. An addition of ferrous iron to 5-ALA enhances heme biosynthesis and increases ATP production through an upregulation of the respiratory complex. Several studies have reported that the administration of 5-ALA and ferrous iron to existing treatment improved the glycemic control in both patients with prediabetes and those with type 2 diabetes mellitus. The additional administration of 5-ALA and ferrous iron to MDM patients on insulin therapy may improve their insulin secretory capacity and glycemic control by improving their mitochondrial function. The findings of this study are expected to provide new treatment options for MDM and improve the patients' glycemic control and prognosis. METHODS/DESIGN This study is a single-arm, open-label pilot intervention study using clinical endpoints to investigate the effects of treatment with 5-ALA plus sodium ferrous citrate (SFC) to patients with MDM on their glucose tolerance. A total of 5 patients with MDM will be administered 5-ALA/SFC (200 mg/d) for 24 weeks. We will perform a 75-g oral glucose tolerance test before and at 24 weeks after the start of this 5-ALA/SFC treatment to evaluate glucose-dependent insulin responses. DISCUSSION To the best of our knowledge, this study will be the first assessment of the effects of 5-ALA/SFC in patients with MDM. This study will obtain an evidence regarding the effectiveness and safety of 5-ALA/SFC for patients with MDM. TRIAL REGISTRATION This study was registered with the University Hospital Medical Information Network (UMIN000040581) on July 1, 2020 and with the Japan Registry of Clinical Trials (jRCTs071200025) on August 3, 2020.

Abstract
Aims/Introduction Controlling postprandial glucose levels in patients with type 1 diabetes is challenging even under the adequate treatment of insulin injection. Recent studies showed that dysregulated glucagon secretion exacerbates hyperglycemia in type 2 diabetes patients, but little is known in type 1 diabetes patients. We investigated whether the glucagon response to a meal ingestion could influence the postprandial glucose excursion in patients with type 1 diabetes. Materials and Methods We enrolled 34 patients with type 1 diabetes and 23 patients with type 2 diabetes as controls. All patients underwent a liquid mixed meal tolerance test. We measured levels of plasma glucose, C‐peptide and glucagon at fasting (0 min), and 30, 60 and 120 min after meal ingestion. All type 1 diabetes patients received their usual basal insulin and two‐thirds of the necessary dose of the premeal bolus insulin. Results The levels of plasma glucagon were elevated and peaked 30 min after the mixed meal ingestion in both type 1 diabetes and type 2 diabetes patients. The glucagon increments from fasting to each time point (30, 60 and 120 min) in type 1 diabetes patients were comparable to those in type 2 diabetes patients. Among the type 1 diabetes patients, the glucagon response showed no differences between the subgroups based on diabetes duration (<5 vs ≥5 years) and fasting C‐peptide levels (<0.10 vs ≥0.10 nmol/L). The changes in plasma glucose from fasting to 30 min were positively correlated with those in glucagon, but not C‐peptide, irrespective of diabetes duration and fasting C‐peptide levels in patients with type 1 diabetes. Conclusions The dysregulated glucagon likely contributes to postprandial hyperglycemia independent of the residual β‐cell functions during the progression of type 1 diabetes.

Abstract
BACKGROUND Older patients with type 2 diabetes mellitus (T2DM) have an increased risk of bone fracture independent of their bone mineral density (BMD), which is explained mainly by the deteriorated bone quality in T2DM compared to that in non-diabetic adults. Sodium-glucose co-transporter (SGLT) 2 inhibitors have been studied in several trials in T2DM, and the Canagliflozin Cardiovascular Assessment Study showed an increased fracture risk related to treatment with the SGLT2 inhibitor canagliflozin, although no evidence of increased fracture risk with treatment with other SGLT2 inhibitors has been reported. The mechanism of the difference in the fracture risk between the SGLT2 inhibitors is unknown, but the differences among the SGLT2 inhibitors in the selectivity of SGLT2 against SGLT1 may affect bone metabolism, since among the SGLT2 inhibitors the selectivity of canagliflozin is lowest. We will investigate whether the SGLT2 inhibitor luseogliflozin, which has the higher SGLT2 selectivity, affects bone metabolism by using high-resolution, peripheral quantitative computed tomography (HR-pQCT) which provides direct in vivo morphometric information about the bone microarchitecture. METHODS/DESIGN This is a single-center, randomized, open-label, active-controlled, parallel pilot trial. Eligible participants are older (age ≥ 60 years) individuals with T2DM with HbA1c levels at 7.0-8.9%. A total of 24 participants will be allocated to either the luseogliflozin group (taking luseogliflozin) or the control group (taking metformin) in a 1:1 ratio to compare the groups' changes in bone microarchitecture of the radius and tibia which are analyzed by HR-pQCT before and at 48 weeks after the administration of each medication. The laboratory data associated with glycemic control and bone metabolism will be collected every 12 weeks during the study. Recruitment began in June 2019. DISCUSSION The reason that we use metformin as an active control is to avoid yielding differences in glycemic control between the luseogliflozin and control groups. Besides, metformin is considered to have a neutral effect on bone. This trial should reveal the effect of luseogliflozin on bone metabolism in older patients with T2DM. TRIAL REGISTRATION The study was registered with the University Hospital Medical Information Network (UMIN000036202) on 1 April 2019 and with the Japan Registry of Clinicla Trials (jRCTs071180061) on 14 March 2019.

Abstract
Objective: Hypothyroidism is not commonly considered a cause of hyperkalemia. We previously reported that hyperkalemia was observed mainly in elderly patients treated with renin-angiotensin-aldosterone system (RAS) inhibitors when levothyroxine treatment was withdrawn for the thyroidectomized patients with thyroid carcinoma to undergo radioactive iodine treatment. Here, we investigated whether acute hypothyroidism causes hyperkalemia in patients who were not treated with RAS inhibitors. We also investigated factors influencing potassium metabolism in hypothyroid patients. Methods: We conducted a single-center, prospective cohort study of 46 Japanese patients with thyroid carcinoma undergoing levothyroxine withdrawal prior to radioiodine therapy. All patients were normokalemic before levothyroxine withdrawal. Blood samples were analyzed 3 times: before, and at 3 and 4 weeks after levothyroxine withdrawal. We investigated factors that may be associated with the elevation of serum potassium levels from a euthyroid state to a hypothyroid state. Results: None of the patients developed symptomatic hyperkalemia. The mean serum potassium level was significantly higher at 4 weeks after levothyroxine withdrawal compared to baseline. The serum sodium levels, the estimated glomerular filtration rate (eGFR), and the plasma renin activity (PRA) decreased significantly as hypothyroidism advanced. In contrast, the plasma levels of adrenocorticotropic hormone, cortisol, aldosterone, and antidiuretic hormone were not changed, while serum thyroid hormone decreased. At 4 weeks after their levothyroxine withdrawal, the patients' serum potassium values were significantly correlated with the eGFR and the PRA. Conclusion: Acute hypothyroidism can cause a significant increase in the serum potassium level, which may be associated with a decreased eGFR and decreased circulating RAS. Abbreviations: ACTH = adrenocorticotropic hormone; ADH = antidiuretic hormone; ATPase = adenosine triphosphatase; eGFR = estimated glomerular filtration rate; HbA1c = glycated hemoglobin; K+ = potassium; Na+ = sodium; PRA = plasma renin activity; RAS = renin-angiotensin-aldosterone system; T4 = thyroxine; TSH = thyroid-stimulating hormone.

Abstract
AIMS To evaluate the glycaemic control of combination therapy with basal insulin and liraglutide, and to explore the factors predictive of efficacy in patients with type 2 diabetes when switched from longstanding basal-bolus insulin therapy. METHODS We studied 41 patients who switched from basal-bolus insulin therapy of more than 3 years to basal insulin/liraglutide combination therapy. Glycaemic control was evaluated at 6 months after switching therapy and used to subdivide the patients into good-responders (HbA1c <7.0% or 1.0% decrease) and poor-responders (the rest of participants). To evaluate the glucose-dependent insulin/glucagon responses without/with liraglutide, a 75-g oral glucose tolerance test (OGTT) was performed twice, before (1st-OGTT) and 2-days after (2nd-OGTT) liraglutide administration. RESULTS Twenty-eight patients (68.3%) were identified as good-responders. No differences were found in baseline characteristics including insulin/glucagon responses during 1st-OGTT between the groups. 2nd-OGTT revealed that paradoxical hyperglucagonemia were significantly improved in both groups, but significant increases in insulin secretory response were observed only in good-responders. Logistic regression analyses revealed that the improvement of the insulin-response during 2nd-OGTT compared to that during 1st-OGTT is associated with the good-responder. CONCLUSIONS Enhancement of glucose-dependent insulin-response under liraglutide administration is a potential predictor of long-term glycaemic control after switching the therapies.

Abstract
A low-carbohydrate diet is effective to improve hyperglycemia via insulin-independent actions. We report here that a low-carbohydrate diet combined with an SGLT2 inhibitor was effective and safe to treat refractory hyperglycemia in the perioperative period in a type 2 diabetes patient complicated with a high titer of insulin antibodies.

Abstract
We report a case involving a 68-year-old woman with rheumatoid arthritis (RA) with acute exacerbated interstitial lung disease (ILD) during certolizumab pegol maintenance therapy. She recovered quickly with steroid pulse therapy and was discharged without deterioration of basal pulmonary function. Immunoblot analysis demonstrated the circulating cleaved interleukin-1β at the phase of acute exacerbation of RA-associated ILD (RA-ILD) in this patient. The findings from this case suggested that the Nod-like receptor pyrin domain-containing protein 3 inflammasome is implicated in acute RA-ILD exacerbation.
