Abstract
Introduction An essential process affecting the course of type 1 diabetes (DM1) is the appearance and duration of clinical remission. One of the most important factors promoting the occurrence of remission is physical activity, due to increased activity of antioxidants, reduces insulin resistance and improves glucose transport. Maximal oxygen capacity (VO2max) is an objective measure of the body's aerobic capacity. To assess VO2max, oxygen uptake should be measured directly during the exercise test. The aim of the study was to evaluate the physical capacity in adults with DM1 and its relationship with the occurrence of partial clinical remission (pCR) during 2 years follow-up. Methods The pCR was assessed by the following mathematical formula: A1c (%) + [4 × insulin dose (U/kg/d)]. The result ⩽9 indicates pCR. VO2max was assessed between 6th and 24th month of diabetes duration using an ergospirometer (COSMED K5 System), during an exercise test carried out on a cycloergometer (RAMP incremental exercise test). Results The study group consisted of 32 adults with DM1. People with pCR were proved to have higher VO2max level [36.0 (33.0-41.5) vs 30.9 (26.5-34.4) ml/min/kg, P = .009. Univariate and multivariate regression confirmed a significant association between VO2max and presence of pCR [AOR 1.26 (1.05-1.52), P = .015]. Duration of remission was longer among group with higher VO2max results [15 (9-24) vs 9 (0-12) months, P = .043]. The positive relationship was observed between diabetes duration and VO2max (rs = 0.484, P = .005). Multivariate linear regression confirms a significant association between remission duration and VO2max (ml/min/kg) (β = 0.595, P = .002). Conclusion The higher VO2max, the better chance of partial clinical remission at 2 years of DM1 and longer duration of remission.

Kennedy EC, Hawkes CP. Approaches to Measuring Beta Cell Reserve and Defining Partial Clinical Remission in Paediatric Type 1 Diabetes. CHILDREN (BASEL, SWITZERLAND) 2024; 11:186. [PMID: 38397298 PMCID: PMC10887271 DOI: 10.3390/children11020186] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 01/26/2024] [Accepted: 02/01/2024] [Indexed: 02/25/2024]
Abstract
CONTEXT Type 1 diabetes (T1D) results from the autoimmune T-cell mediated destruction of pancreatic beta cells leading to insufficient insulin secretion. At the time of diagnosis of T1D, there is residual beta cell function that declines over the subsequent months to years. Recent interventions have been approved to preserve beta cell function in evolving T1D. OBJECTIVE The aim of this review is to summarise the approaches used to assess residual beta cell function in evolving T1D, and to highlight potential future directions. METHODS Studies including subjects aged 0 to 18 years were included in this review. The following search terms were used; "(type 1 diabetes) and (partial remission)" and "(type 1 diabetes) and (honeymoon)". References of included studies were reviewed to determine if additional relevant studies were eligible. RESULTS There are numerous approaches to quantifying beta cell reserve in evolving T1D. These include c-peptide measurement after a mixed meal or glucagon stimuli, fasting c-peptide, the urinary c-peptide/creatinine ratio, insulin dose-adjusted haemoglobin A1c, and other clinical models to estimate beta cell function. Other biomarkers may have a role, including the proinsulin/c-peptide ratio, cytokines, and microRNA. Studies using thresholds to determine if residual beta cell function is present often differ in values used to define remission. CONCLUSIONS As interventions are approved to preserve beta cell function, it will become increasingly necessary to quantify residual beta cell function in research and clinical contexts. In this report, we have highlighted the strengths and limitations of the current approaches.

Abstract
Objective The occurrence of partial remission (honeymoon phase) in type 1 diabetes (T1D) has been associated with a reduced risk of chronic microvascular complications of diabetes. We have published case reports showing that a combination therapy with the DPP-4 inhibitor sitagliptin plus vitamin D3 (VIDPP-4i) can prolong the honeymoon phase in patients with new-onset T1D. In the present case-control study, we investigated the frequency of occurrence of clinical remission (CR) in patients with new-onset T1D after VIDPP-4i treatment. Subjects and methods In this case-control study, we collected data spanning 10 years from medical records of 46 patients (23 females) recently diagnosed with T1D. Overall, 27 participants with CR (insulin dose-adjusted glycated hemoglobin [IDAA1c] ≤ 9) at 12 or 24 months composed the case group, and 19 participants without CR served as the control group. Chi-square with Yates correction was used to analyze the association between VIDPP-4i use and CR, and odds ratio (OR) was used to determine the chance of CR due to VIDPP-4i treatment exposure. Results In all, 37 patients (80.4%) experienced CR at some time over 24 months. The mean CR duration was 13.15 ± 9.91 months. Treatment with VIDPP-4i was significantly associated with CR. At 24 months, the OR of CR after VIDPP-4i exposure was 9.0 (95% confidence interval [CI] 2.21-30.18, p = 0.0036). Additionally, 9 (33.6%) and 4 (14.8%) patients in the VIDPP-4i group experienced insulin-free CR at 12 and 24 months, respectively. Conclusion Therapy with VIDPP-4i was associated with a higher frequency and duration of the honeymoon phase. Randomized controlled trials are needed to confirm these findings.

Abstract
Little is known about complete remission in Type 1 diabetes mellitus (T1D) with the discontinuance of insulin treatment for a period of time. In this retrospective study we analysed the frequency and factors of onset and duration of 1. remission and 2. complete remission in children and adolescents with T1D from the Children Diabetes Centre in Bratislava, Slovakia. A total of 529 individuals with T1D, aged < 19 years (8.5 ± 4.3 years) at diabetes onset were included in the study. Remission was defined by HbA1c < 7.0% (53 mmol/mol) and an insulin daily dose < 0.5 IU/kg (and 0 IU/kg for complete remission). Remission occurred in 210 (39.7%) participants, and 15 of them had complete remission (2.8% from all participants). We have identified a new independent factor of complete remission onset (higher C-peptide). Complete remitters had a longer duration of remission compared with other remitters and also differed in lower HbA1c levels. No association was seen with autoantibodies or genetic risk score for T1D. Thus, not only partial but also complete remission is influenced by factors pointing toward an early diagnosis of T1D, which is important for better patient outcome.

Abstract
Type 1 diabetes is a chronic autoimmune disorder that results in destruction of insulin-producing cells in the pancreas. The autoimmune process is thought to be waxing and waning resulting in variable endogenous insulin secretion ability. An example of this is the honeymoon phase or partial remission phase of type 1 diabetes, during which optimal control of blood glucoses can be maintained with significantly reduced exogenous insulin, and occasionally exogenous insulin can be temporarily discontinued altogether. Understanding this phase is important because even fairly small amounts of endogenous insulin secretion is associated with reduced risk of severe hypoglycemia and microvascular complications.

Abstract
AIM To investigate whether physical activity is associated with the occurrence of remission in adults with type 1 diabetes. METHODS Ninety nine adult participants with newly diagnosed type 1 diabetes were enroled into a prospective, observational study. The participants were advised to exercise 2-3 times a week with moderate intensity for a one-year period. Physical activity was assessed by a self-administrated questionnaire on every fourth visit. We counted the months in which participants fulfiled a partial-remission criteria: HbA1c < 6.5%, C-peptide > 0.5 ng/ml, and daily dose of insulin <0.3 U/kg/day. We assigned the participants to two groups: MORE EFFORT and LESS EFFORT, depending on the median value of physical activity in the studied population. RESULTS The occurrence of the remission achieved statistical significance at 6th month with a greater prevalence in MORE EFFORT group (55% vs. 35% p = 0.047). In multivariate logistic regression analysis for the occurrence of remission at 12th month, physical activity before the diagnosis was the only variable that influences the occurrence of the remission (adjusted odds ratios = 3.32 [95% confidence intervals 1.25-8.80]; p = 0.02). CONCLUSION In adults with newly diagnosed type 1 diabetes physical activity before the diagnosis is associated with higher occurrence of remission.

Abstract
CONTEXT Partial remission (PR) is a specific stage in type 1 diabetes (T1D). Although human leukocyte antigen (HLA) class II loci are the strongest genetic determinants in T1D, the relationship between PR and HLA remains unclear. OBJECTIVE To investigate the association between PR status and HLA genotypes in patients with T1D. METHODS A total of 237 patients with T1D were included. PR was defined according to C-peptide ≥300 pmol/L. The frequency of PR and peak C-peptide levels during remission phase were compared according to HLA status. Clinical characteristics including age of onset and diabetes autoantibodies were collected. All analyses were duplicated when subjects were divided into childhood- and adult-onset T1D. RESULTS The median follow-up time was 24 months, 65.8% (156/237) of patients with T1D went into PR. DR9/DR9 carriers had a lower PR rate (44.2% vs 70.6%, P = .001) and were less likely to enter PR (OR = 0.218, 95% CI 0.098-0.487, P < .001) than the non-DR9/DR9 carriers, observed in both childhood- and adult-onset T1D. Besides, the peak C-peptide level during PR phase was also lower in DR9/DR9 carriers, and more notable in adult-onset T1D. When compared with non-DR9/DR9 carriers, T1D with DR9/DR9 genotype presented an older age of onset and a lower positivity of zinc transporter 8 antibody (ZnT8A), and the lower trend of ZnT8A was only found in adult-onset T1D (P = .049). CONCLUSION Patients with T1D carrying susceptible DR9/DR9 are less prone to undergo PR. Additionally, the recovery extent of β-cell function during the PR phase tends to be lower in adults carrying DR9/DR9, which might be associated with ZnT8A.

Abstract
BACKGROUND Partial remission (PR) is a special stage in type 1 diabetes (T1D). The different patterns of PR frequency, characteristics, and determinants in juvenile and adult patients are unclear, and data on Chinese are lacking. METHODS A total of 186 children and 114 adults with T1D who were regularly followed up in a cohort were included for analysis. PR was defined according to C-peptide ≥300 pmol/L or index of insulin dose-adjusted hemoglobin A1c ≤9, as previously recommended. C-peptide and islet autoantibodies were determined with chemiluminescence and radioimmunoassay, respectively. RESULTS The frequency of PR in children was higher than that in adults, with the proportion being 69.9% and 58.8%, respectively (P < .05). For juvenile-onset T1D, the frequency of PR gradually decreased as the onset age decreased, from 87.5% in 13- to 18-year olds to 46.5% in under 6-year olds. Multivariable analyses showed that onset age and male sex were positively related with the frequency of PR in children, while the related factors in adults were initial glycosylated hemoglobin A1c and C-peptide levels. The median PR duration was similar in children (14.8 ± 1.2 months) and adults (16.4 ± 1.9 months). Older onset age was related with a longer PR duration in children, but no such associations were found in adult individuals. CONCLUSIONS Children and adults with T1D have different patterns on PR frequency, clinical characteristics, and determinants. For patients during this special phase, the relatively high C-peptide level and to reduce insulin dosage accordingly should be emphasized in clinical practice.
