Abstract Objectives Most patients with type 1 diabetes (T1D) experience a transient phase of partial remission (PR). This study aimed to identify the demographic and clinical factors associated with PR. Methods This was a longitudinal retrospective cohort study of 133 children and adolescents with T1D. PR was defined by the gold standard insulin dose-adjusted hemoglobin A1c (HbA1c) (IDAA1c) of ≤9. Results Remission was observed in 77 (57.9%) patients. At diagnosis, remitters had significantly higher pH (7.3 ± 0.12 vs. 7.23 ± 0.15, p=0.003), higher C-peptide levels (0.45 ± 0.31 ng/mL vs. 0.3 ± 0.22, p=0.003), and they were significantly older (9.3 ± 3.6 years vs. 7.3 ± 4.2, p=0.008) compared with non-remitters. PR developed more frequently in patients without diabetic ketoacidosis (DKA) (p=0.026) and with disease onset after age 5 (p=0.001). Patients using multiple daily insulin regimen were more likely to experience PR than those treated with a twice daily regimen (63.9 vs. 32%, p=0.004). Only age at onset was an independent predictor of PR (OR: 1.12, 95% CI: 1-1.25; p=0.044). Remitters had lower HbA1c levels and daily insulin requirement from diagnosis until one year after diagnosis (p<0.001). PR recurred in 7 (9%) patients. The daily insulin requirement at three months was lower in remitters with PR recurrence compared to those without (0.23 ± 0.14 vs. 0.4 ± 0.17 U/kg/day, p=0.014). Conclusions Addressing factors associated with the occurrence of PR could provide a better comprehension of metabolic control in T1D. The lack of DKA and higher C-peptide levels may influence PR, but the main factor associated with PR presence was older age at onset. PR may recur in a small proportion of patients.

(1) Background: Intensive insulin therapy using continuous subcutaneous insulin infusion (CSII) with continuous real-time glucose monitoring (rt CGM) is the best option for patients with T1D. The recent introduction of a technology called Advanced Hybrid Closed Loop (AHCL) represents a new era in the treatment of type 1 diabetes, the next step towards better care, as well as improving the effectiveness and safety of therapy. The aim is to present the case of a T1D patient with a borderline total daily dose of insulin being treated with the Medtronic AHCL system in automatic mode. (2) Materials and Methods: A 9-year-old boy, from October 2020, with type 1 diabetes in remission was connected to the Minimed™ 780G (AHCL) system in accordance with the manufacturer’s recommendations (daily insulin dose > 8 units, age > 7). Records of the patient’s history were collected from visits to The Department of Children’s Diabetology, as well as from the Medtronic CareLink™ software and the DPV SWEET program from October 2020 to April 2021. (3) Results: The patient’s total daily insulin requirement decreased in the first 6 weeks after the AHCL was connected, which may reflect the remission phase (tight glycemic control with a healthy lifestyle). The lowest daily insulin requirement of 5.7 units was also recorded. In a three-month follow-up of the patient treated with AHCL, it was found that for almost 38% of the days the insulin dose was less than 8 IU. (4) Conclusions: The AHCL system allows safe and effective insulin therapy in automatic mode, as well as in patients with a lower daily insulin requirement. The AHCL system should be considered a good therapeutic option for patients from the onset of T1D, as well in the remission phase.

To evaluate the characteristics and determinants of partial remission (PR) in Belgian children with type 1 diabetes (T1D), we analyzed records of 242 children from our center. Clinical and biological features were collected at diagnosis and during follow-up. PR was defined using the insulin-dose-adjusted A1C definition. PR occurred in 56.2% of patients and lasted 9.2 months (0.5 to 56.6). 25.6% of patients entered T1D with DKA, which correlated with lower PR incidence (17.6% versus 82.3% when no DKA). In our population, lower A1C levels at diagnosis were associated with higher PR incidence and in young children (0–4 years) initial A1C levels negatively correlated with longer PR. Early A1C levels were predictive of PR duration since 34% of patients had long PRs (>1 year) when A1C levels were ≤6% after 3 months whereas incidence of long PR decreased with higher A1Cs. C-peptide levels were higher in patients entering PR and remained higher until 3 years after diagnosis. Initial antibody titers did not influence PR except for anti-IA2 titers that correlated with A1C levels after 2 years. Presence of 2 versus 1 anti-islet antibodies correlated with shorter PR. PR duration did not influence occurrence of severe hypoglycemia or diabetes-related complications but was associated with lower A1C levels after 18 months. We show that, at diagnosis of T1D, parameters associated withβ-cell mass reserve (A1C, C-peptide, and DKA) correlate with the occurrence of PR, which affects post-PR A1C levels. Further research is needed to determine the long-term significance of PR.

Background. Type 1 diabetes (T1D) in adolescents is associated with alterations in the insulin-like factor system probably caused both by a deranged metabolism and insulinopenia in the portal vein. Objective. To study how the circulating IGF-1 is affected at diagnosis and during subsequent years in adolescents with T1D. Methods. Ten girls and ten boys with type 1 diabetes (T1D), aged 13.0 ± 1.4 (mean ± SD) years at diagnosis, took part in the study. Blood samples were drawn at diagnosis and after 3, 9, 18, and 48 months. HbA1c, total IGF-1, and C-peptide were measured. Results. At diagnosis, the patients had high HbA1c, low IGF-1, and measurable C-peptide. After the start of insulin treatment, maximal improvement in glycemic control and IGF-1 occurred within 3 months and then both tended to deteriorate, that is, HbA1c to increase and IGF-1 to decrease. C-peptide decreased with time, and after 4 years, half of the patients were C-peptide negative. At diagnosis, C-peptide correlated positively to IGF-1 (r=0.50; p<0.03). C-peptide correlated negatively with insulin dose (U/kg) after 18 and 48 months from diagnosis (r=−0.48; p<0.03 and r=−0.72; p<0.001, resp.). Conclusions. In conclusion, our results show that in newly diagnosed adolescents with type 1 diabetes and deranged metabolism, the IGF-1 level is low and rapidly improves with insulin treatment but later tends to decrease concomitantly with declining endogenous insulin secretion.

Abstract Objective: Despite intensive insulin treatment in patients with type 1 diabetes (T1D), many of them do not reach the glycemic target goal. We performed a network meta-analysis to evaluate the efficacy and safety of additional therapy to insulin in patients with T1D. Methods: We searched CENTRAL, MEDLINE, EMBASE, and Science Citation Index Expanded from January 1970 until September 2019 to identify randomized controlled trials (RCTs) in T1D patients treated with insulin and metformin, sodium-glucose cotransporter (SGLT) inhibitors or glucagon-like peptide-1 receptor agonists (GLP-1 RAs). We performed direct and indirect network meta-analysis using Bayesian models and generated rankings of the different hypoglycemia agents by generating mixed treatment comparison. Results: With 23 RCTs (n = 5,151), we performed the network meta-analysis using eight groups; 1) insulin alone, 2) insulin and metformin, 3) insulin and canagliflozin, 4) insulin and dapagliflozin, 5) insulin and empagliflozin, 6) insulin and sotagliflozin, 7) insulin and liraglutide, and 8) insulin and exenatide. Compared with insulin alone, HbA1c was significantly lower in the group treated with insulin and sotagliflozin (mean difference: -0.43%; 95% credible intervals: -0.62 to -0.23). Total daily insulin dose was significantly lower in the insulin and sotagliflozin group by 6.3 U/day than in insulin alone group. Compared with insulin alone, body weight was significantly decreased in the group treated with canagliflozin by 4.5kg, sotagliflozin by 2.8kg, and exenatide by 5.1 kg, respectively. Severe hypoglycemic episodes did not differ between the groups. Conclusions: In patients with T1D, sotagliflozin add-on to insulin decreased HbA1c levels, daily insulin dose, and body weight without hypoglycemia compared to insulin monotherapy. Combined treatment of canagliflozin or exenatide with insulin was effective in weight loss compared with insulin alone in these patients.

Introduction: Metformin has been demonstrated to enhance cardioprotective benefits in type 1 diabetes (T1DM). Although glycemic variability (GV) is associated with increased risk of CVD in diabetes, there is a scarcity of research evaluating the effect of metformin on GV in T1DM. Objectives: In the present study, the effects of adjuvant metformin therapy on GV and metabolic control in T1DM were explored. Patients and methods: A total of 65 adults with T1DM were enrolled and subjected to physical examination, fasting laboratory tests and continuous glucose monitoring, and subsequently randomized 1:1 to 3 months of 1000- 2000 mg metformin daily add-on insulin (MET group, n=34) or insulin (Non-MET group, n=31). After, baseline measurements were repeated. Results: The mean amplitude of glycemic excursions was substantially reduced in MET group, compared with Non-MET group [-1.58 (-3.35,0.31) mmol/L versus 1.36 (-1.12,2.24) mmol/L, P=0.004]. In parallel, the largest amplitude of glycemic excursions [-2.83 (-5.47,-0.06) mmol/L versus 0.45 (-1.29,4.48) mmol/L, P=0.004], the standard deviation of blood glucose [-0.85 (-1.51,0.01) mmol/L versus -0.14 (-0.68,1.21) mmol/L, P=0.015], and the coefficient of variation [-6.66 (-15.00,1.50) % versus -1.60 (-6.28,11.71) %, P=0.012] all demonstrated improvement in the MET group, compared with the Non-MET group. Significant reduction in insulin dose, body mass index and body weight were observed in patients in MET, not those in Non-MET group. Conclusion: Additional metformin therapy improved GV in adults with T1DM, as well as improving body composition and reducing insulin requirement. Hence, metformin as adjunctive therapy has potential prospects in reducing the CVD risk in patients with T1DM in the long term.
