- Background: A composite metric for the quality of glycemia from continuous glucose monitor (CGM) tracings could be useful for assisting with basic clinical interpretation of CGM data. Methods: We assembled a data set of 14-day CGM tracings from 225 insulin-treated adults with diabetes. Using a balanced incomplete block design, 330 clinicians who were highly experienced with CGM analysis and interpretation ranked the CGM tracings from best to worst quality of glycemia. We used principal component analysis and multiple regressions to develop a model to predict the clinician ranking based on seven standard metrics in an Ambulatory Glucose Profile: very low–glucose and low-glucose hypoglycemia; very high–glucose and high-glucose hyperglycemia; time in range; mean glucose; and coefficient of variation. Results: The analysis showed that clinician rankings depend on two components, one related to hypoglycemia that gives more weight to very low-glucose than to low-glucose and the other related to hyperglycemia that likewise gives greater weight to very high-glucose than to high-glucose. These two components should be calculated and displayed separately, but they can also be combined into a single Glycemia Risk Index (GRI) that corresponds closely to the clinician rankings of the overall quality of glycemia (r = 0.95). The GRI can be displayed graphically on a GRI Grid with the hypoglycemia component on the horizontal axis and the hyperglycemia component on the vertical axis. Diagonal lines divide the graph into five zones (quintiles) corresponding to the best (0th to 20th percentile) to worst (81st to 100th percentile) overall quality of glycemia. The GRI Grid enables users to track sequential changes within an individual over time and compare groups of individuals. Conclusion: The GRI is a single-number summary of the quality of glycemia. Its hypoglycemia and hyperglycemia components provide actionable scores and a graphical display (the GRI Grid) that can be used by clinicians and researchers to determine the glycemic effects of prescribed and investigational treatments.

- Background and aims: This 52 week, parallel-arm, open-label, phase 3 study compared two doses of the once weekly GLP-1 receptor agonist dulaglutide (DU) versus bedtime insulin glargine, all combined with pre-meal insulin lispro with or without metformin, in patients with type 2 diabetes mellitus inadequately controlled on conventional insulin therapy. Insulin glargine and insulin lispro were titrated to attempt to reach glycaemic targets.Materials and methods: Patients (N = 884; mean baseline characteristics: age 59.4 years; duration of diabetes 12.7 years; HbA1c 8.5%; body weight 91.1 kg; BMI 32.5 kg/m2; total daily insulin dose 56 U) were randomised (1:1:1) to once weekly DU 1.5 mg, DU 0.75 mg, or bedtime insulin glargine titrated-to-target. The primary objective was to compare the change in HbA1c from baseline of DU 1.5 mg with insulin glargine at 26 weeks for noninferiority (margin 0.4%) and if met, then superiority was tested.Results: At 26 and 52 weeks, both DU doses were statistically superior to insulin glargine for HbA1c change from baseline. Insulin glargine was associ-ated with greater fasting serum glucose reduction compared with both DU doses. The mean prandial insulin doses at 26 weeks were 93 U for DU 1.5 mg, 97 U for DU 0.75 mg, and 68 U for insulin glargine. The insulin glargine dose was 65 U. Similar insulin doses were observed at 52 weeks. Body weight decreased with DU 1.5 mg and increased with DU 0.75 mg and insulin glar-gine at 52 weeks. The rate of documented symptomatic hypoglycaemia (≤3.9 mmol/L) at 52 weeks was 31.0, 35.0,and 39.9 events/patient/year for DU 1.5 mg, DU 0.75 mg, and insulin glargine, respectively. The number of severe hypoglycaemia events was 11 for DU 1.5 mg, 15 for DU 0.75 mg, and 22 for insulin glargine. Nausea, diarrhoea, and vomiting were more common with DU 1.5 mg (25.8%, 16.6%, and 12.2%, respectively) and DU 0.75 mg (17.7%, 15.7%, and 10.6%) versus insulin glargine (3.4%, 6.1%, and 1.7%).Conclusion: DU compared to insulin glargine, both combined with insu-lin lispro, resulted in better glycaemic control, less body weight gain, no in-creased risk of hypoglycaemia, and more common reporting of gastrointes-tinal adverse events.

- AIM: To investigate treatment satisfaction with semaglutide, a once-weekly glucagon-like peptide-1 receptor agonist, versus placebo/active comparators in theSUSTAIN clinical trial programme.METHODS: In SUSTAIN 2-5 and 7, the Diabetes Treatment Satisfaction Questionnaire was used to evaluate patient-perceived treatment satisfaction, hyperglycaemia and hypoglycaemia. Post hoc subgroup analyses were conducted to explore the effects of gastrointestinal adverse events (GI AEs), weight loss (>= 5%) or achieving glycaemic (HbA1c < 7%) targets on treatment satisfaction.RESULTS: Overall treatment satisfaction increased from baseline to end of treatment with all treatments across trials. Improvements were significantly greater with semaglutide versus comparators/placebo in SUSTAIN 2-5 (all P < 0.05), and generally greater in patients who achieved versus did not achieve weight loss and glycaemic targets, often with greater improvements with semaglutide 1.0 mg versus comparator/placebo in both weight loss groups. In SUSTAIN 7, improvements in overall treatment satisfaction were generally similar between semaglutide and dulaglutide, irrespective of weight loss or glycaemic control. In SUSTAIN 7, changes in overall treatment satisfaction score were generally lower in patients with versus without GI AEs at week 16 (except dulaglutide 0.75 mg), but similar by week 40. Perceived hyperglycaemia was significantly reduced from baseline to end of treatment with semaglutide versus all comparators/placebo (all P < 0.05). No differences between treatments were observed for perceived hypoglycaemia.CONCLUSIONS: Semaglutide was associated with significantly greater (SUSTAIN 2-5) or similar (SUSTAIN 7) improvements in overall treatment satisfaction versus comparators/placebo. Improvements in overall treatment satisfaction were generally greater in patients achieving versus not achieving treatment targets.

- OBJECTIVE: To establish the clinical phenotype and genetic background in a family with diabetes insipidus.MATERIAL AND METHODS: The subjects were a sister and brother, aged 34 and 27 years, respectively, with a history of polyuria since infancy. Clinical testing confirmed a diagnosis of congenital nephrogenic diabetes insipidus (CNDI) in both. Samples of purified genomic DNA were analysed.RESULTS: The sequence of the entire coding region of the AQP2 gene as well as the AVPR2 gene was determined. Sequence analysis revealed no variations in the AQP2 gene. A missense variation in exon 2 of the AVPR2 gene (g.685G>A), predicting a p.Asp85Asn substitution, was identified in the X-chromosome of the affected male and one allele in the sister and the asymptomatic mother. The p.Asp85Asn variation in AVPR2 is known to cause CNDI, and has previously been described as inducing a partial phenotype treatable with dDAVP. However, in this family dDAVP had no influence on urine osmolality, whereas combination therapy with indomethacin and hydrochlorothiazide increased urine osmolality to 299 mosm/l in the proband. A skewed X-inactivation pattern (93%) occurring in the normal X allele was recognized in the sister.CONCLUSIONS: This study demonstrates the effect of skewed X-chromosome inactivation associated with X-linked CNDI. Polydipsia in early childhood could be due to X-linked CNDI despite affecting both genders. The significant heterogeneity in the clinical phenotype in CNDI carries a risk of diagnostic misinterpretation and emphasizes the need for genetic characterization. Treatment combining indomethacin and hydrochlorothiazide results in a marked response on both urine output and urine osmolality.

- The use of different approaches for design and results presentation of studies for the clinical performance evaluation of continuous glucose monitoring (CGM) systems has long been recognized as a major challenge in comparing their results. However, a comprehensive characterization of the variability in study designs is currently unavailable. This article presents a scoping review of clinical CGM performance evaluations published between 2002 and 2022. Specifically, this review quantifies the prevalence of numerous options associated with various aspects of study design, including subject population, comparator (reference) method selection, testing procedures, and statistical accuracy evaluation. We found that there is a large variability in nearly all of those aspects and, in particular, in the characteristics of the comparator measurements. Furthermore, these characteristics as well as other crucial aspects of study design are often not reported in sufficient detail to allow an informed interpretation of study results. We therefore provide recommendations for reporting the general study design, CGM system use, comparator measurement approach, testing procedures, and data analysis/statistical performance evaluation. Additionally, this review aims to serve as a foundation for the development of a standardized CGM performance evaluation procedure, thereby supporting the goals and objectives of the Working Group on CGM established by the Scientific Division of the International Federation of Clinical Chemistry and Laboratory Medicine.

- The prevalence of type 1 diabetes (T1D) is increasing worldwide. T1D reduces life expectancy due to complications including cardiovascular disease. Sodium-glucose co-transporter (SGLT) inhibitors are a new class of drugs developed to treat type 2 diabetes (T2D), and now they can be used as an adjunct to insulin in T1D. In clinical trials, they have been shown to improve glycaemic control and decrease body weight without the risk of increased hypoglycaemia and with a reduction in insulin dose. Four SGLT2 inhibitors have been approved in Europe for the treatment of T2D, while only dapagliflozin and sotagliflozin, a dual SGLT1 and SGLT2 inhibitor approved in 2019, have been approved for the treatment of T1D. Both can be used as an adjunct therapy in combination with insulin in adults with a body mass index (BMI) of ≥27 kg/m2, inadequately controlled with insulin. In Europe, dapagliflozin is the only currently available SGLT2 inhibitor indcated as adjunct therapy for patients with T1D. The subgroup of patients with a BMI of ≥27 kg/m2 from the DEPICT-1 and -2 trials (Dapagliflozin Evaluation in Patients with Inadequately Controlled Type 1 diabetes) showed similar reduction in hyperglycaemia and body weight but no significant increased risk of diabetic ketoacidosis (DKA) than the overall trial population. The risk of DKA has been shown to increase in patients with T1D treated with adjunct therapy with SGLT2 inhibitors, and studies on sotagliflozin and empagliflozin have suggested a dose response. Thus, it is important to educate patients and doctors how to recognize symptoms of upcoming DKA and mitigate it. An independent DKA education programme has recently been developed to instruct patients with T1D being treated with SGLT inhibitor therapies with and without insulin pumps to prevent, identify and treat DKA. Despite these considerations, clinical trials support the use of SGLT2 inhibitors in the management of T1D. The benefits and potential risks of dapagliflozin as an adjunct therapy to insulin in adults with T1D should be considered in each individual case. Here we discuss the efficacy and safety of dapagliflozin as adjunct therapy in patients with T1D.
