Ekelund C, Dereke J, Nilsson C, Landin-Olsson M. Are soluble E-selectin, ICAM-1, and VCAM-1 potential predictors for the development of diabetic retinopathy in young adults, 15-34 years of age? A Swedish prospective cohort study. PLoS One 2024; 19:e0304173. [PMID: 38843125 PMCID: PMC11156360 DOI: 10.1371/journal.pone.0304173] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Accepted: 05/08/2024] [Indexed: 06/09/2024] Open
Abstract
The aim of this study was to determine plasma levels of three adhesion molecules that may contribute to the development of diabetic retinopathy; soluble endothelial selectin (sE-selectin), soluble intercellular adhesion molecule-1 (sICAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1), in young adults, aged 15-34 years at diagnosis of diabetes, to find potential predictors for development of retinopathy, and to evaluate their relation to diabetes associated autoantibodies. Participants with type 1 (n = 169) and type 2 diabetes (n = 83) were selected from the complications trial of the Diabetes Incidence Study in Sweden and classified in two subgroups according to presence (n = 80) or absence (n = 172) of retinopathy as determined by retinal photography at follow-up 8-10 years after diagnosis of diabetes. Blood samples were collected at diagnosis in 1987-88. The levels of sE-selectin, sICAM-1, and sVCAM-1 were analysed by enzyme-linked immunosorbent assay and islet cell antibodies by a prolonged two-colour immunofluorescent assay. Mean HbA1c (p<0.001) and clinical characteristics: mean body mass index (p = 0.019), systolic blood pressure (p = 0.002), diastolic blood pressure (p = 0.003), male gender (p = 0.026), and young age at diagnosis of diabetes (p = 0.015) remained associated with development of retinopathy in type 1 diabetes. However, in a multivariate analysis only HbA1c remained as a risk factor. sE-selectin was significantly higher in the group with type 2 diabetes and retinopathy, compared to the group with type 2 diabetes without retinopathy (p = 0.04). Regarding sE-selectin, sICAM-1, and sVCAM-1 in participants with type 1 diabetes, no differences were observed between the groups with or without retinopathy. This trial confirmed the role of HbA1c and clinical characteristics as predictors for development of retinopathy in type 1 diabetes. sE-selectin stands out as a potential predictor for development of retinopathy in type 2 diabetes, whereas a predictive role for sICAM-1 and sVCAM-1 could not be identified neither for type 1 nor type 2 diabetes.

The role of sex on the prevalence of cardiovascular risk factors in children and adolescents with Type 1 diabetes: The SWEET international database. Diabetes Res Clin Pract 2024; 210:111616. [PMID: 38490494 DOI: 10.1016/j.diabres.2024.111616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 03/02/2024] [Accepted: 03/11/2024] [Indexed: 03/17/2024]
Abstract
OBJECTIVE To assess the prevalence of cardiovascular risk factors (CVRFs) in children and adolescents with type 1 diabetes (T1D) in the International SWEET registry and the possible role of clinical variables in modifying the risk of having single or multiple CVRFs. STUDY DESIGN The study is a cross-sectional study. Cut-off points for CVRFs were fixed according to International Society for Pediatric and Adolescent Diabetes (ISPAD) guidelines and WHO parameters: LDL cholesterol (LDL-C) > 100 mg/dL; Systolic Blood Pressure (BP-SDS) > 90th percentile for sex, age, and height; BMI-SDS > 2SD for sex and age. Logistic regression models were applied to evaluate variables associated with at least 1 or 2 CVRFs among registry children and adolescents. RESULTS 29,649 individuals with T1D (6-18 years, T1D ≥ 2 years) participating in the SWEET prospective multicenter diabetes registry were included. In the cohort, 41 % had one or more CVRFs, and 10 % had two or more CVRFs. Thirty-five percent of enrolled individuals had LDL-C > 100 mg/dL, 26 % had BMI-SDS > 2SD, and 17 % had Systolic BP-SDS > 90th percentile. Females had higher frequency than males of having 1 or 2 CVRFs (45.1 % vs 37.4 %, 11.8 % vs 7.8 %; p < 0.001). Multivariable logistic regression models showed that sex (female), HbA1c category (>7.0 %), and age (>10 years) were associated with a higher chance of having at least 1 or 2 CVRFs (p < 0.001). CONCLUSIONS In children and adolescents with T1D, female sex, in addition to HbA1c above 7 %, and older age (>10 years) was associated with a higher risk of having at least a CVRF (LDL-C, BMI-SDS, BP) according to internationally defined cut-offs.

Ther Adv Endocrinol Metab 2023; 14:20420188231220130. [PMID: 38152658 PMCID: PMC10752105 DOI: 10.1177/20420188231220130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Accepted: 11/11/2023] [Indexed: 12/29/2023] Open
Abstract
Background Handling of the dawn phenomenon (DP) with multiple daily insulin injection (MDII) regimen is a real challenge. Objective We aimed to demonstrate the effectiveness of a dual-basal-insulin (a long-acting glargine and an intermediate-acting neutral protamine Hagedorn (NPH)) regimen for the management of DP in children with type 1 diabetes mellitus (T1DM). The primary efficacy outcome was to overcome morning hyperglycemia without causing hypoglycemia during the non-DP period of the night. Design Retrospective cohort study. Method Charts of 28 children with T1DM (12 female; 42.8%, mean age 13.7 ± 2.1 years) treated with MDII were retrospectively reviewed. The median duration of diabetes was 4.5 years (range 2-13.5 years). DP was diagnosed using a threshold difference of 20 mg/dL (0.1 mmol/L) between fasting capillary blood glucose at 3 a.m. and prebreakfast. NPH was administered at midnight in addition to daily bedtime (08.00-09.00 p.m.) glargine (dual-basal-insulin regimen). Midnight, 03:00 a.m., prebreakfast and postprandial capillary blood glucose readings, insulin-carbohydrate ratios, and basal-bolus insulin doses were recorded the day before the dual-basal-insulin regimen was started and the day after the titration of the insulin doses was complete. Body mass index standard deviation scores (BMI SDS) at the onset-3rd-12th month of treatment were noted. Results Before using dual basal insulin, prebreakfast capillary blood glucose levels were greater than those at midnight and at 03:00 a.m. (F = 64.985, p < 0.01). After titration of the dual-basal-insulin doses, there were significant improvements such that there were no statistically significant differences in the capillary blood glucose measurements at the three crucial time points (midnight, 03.00 a.m., and prebreakfast; F = 1.827, p = 0.172). No instances of hypoglycemia were reported, and the total daily insulin per kilogram of body weight did not change. The BMI SDS remained steady over the course of the 1-year follow-up. Conclusion In this retrospective cohort study, the dual-basal-insulin regimen, using a long-acting glargine and an intermediate-acting NPH, was effective in overcoming early morning hyperglycemia due to insulin resistance in the DP. However, the effectiveness of the dual-basal-insulin regimen needs to be verified by prospective controlled studies using continuous glucose monitoring metrics or frequent blood glucose monitoring.

Abstract
BACKGROUND Accumulating observational studies have identified associations between type 1 diabetes (T1D) and polycystic ovary syndrome (PCOS). Still, the evidence about the causal effect of this association is uncertain. METHODS We performed a two-sample Mendelian randomization (MR) analysis to test for the causal association between T1D and PCOS using data from a large-scale biopsy-confirmed genome-wide association study (GWAS) in European ancestries. We innovatively divided T1D into nine subgroups to be analyzed separately, including: type1 diabetes wide definition, type1 diabetes early onset, type 1 diabetes with coma, type 1 diabetes with ketoacidosis, type 1 diabetes with neurological complications, type 1 diabetes with ophthalmic complications, type 1 diabetes with peripheral circulatory complications, type 1 diabetes with renal complications, and type 1 diabetes with other specified/multiple/unspecified complications. GWAS data for PCOS were obtained from a large-scale GWAS (10,074 cases and 103,164 controls) for primary analysis and the IEU consortium for replication and meta-analysis. Sensitivity analyses were conducted to evaluate heterogeneity and pleiotropy. RESULTS Following rigorous instrument selection steps, the number of SNPs finally used for T1D nine subgroups varying from 6 to 36 was retained in MR estimation. However, we did not observe evidence of causal association between type 1 diabetes nine subgroups and PCOS using the IVW analysis, MR-Egger regression, and weighted median approaches, and all P values were > 0.05 with ORs near 1. Subsequent replicates and meta-analyses also yielded consistent results. A number of sensitivity analyses also did not reveal heterogeneity and pleiotropy, including Cochran's Q test, MR-Egger intercept test, MR-PRESSO global test, leave-one-out analysis, and funnel plot analysis. CONCLUSION This is the first MR study to investigate the causal relationship between type 1 diabetes and PCOS. Our findings failed to find substantial causal effect of type 1 diabetes on risk of PCOS. Further randomized controlled studies and MR studies are necessary.

Abstract
Though insulin resistance (IR) was previously considered a feature of only type 2 Diabetes (T2DM), its development in type 1 Diabetes (T1DM) is not an uncommon occurrence, the causes of which are multifactorial (gender, pubertal status, diabetes duration, ethnicity, genetics, adiposity, glycemic control, chronic inflammation). Despite improvements in glucose, blood pressure and lipid profile, vascular complications (coronary artery disease and nephropathy) continue to remain common causes of morbidity and mortality in T1DM. Aggressive glycemic control reduces but does not eliminate the risk of IR. IR accelerates the development of micro and macrovascular complications, many of which can be potentially reversed if diagnosed and managed early. Lack of endogenous insulin production makes estimation of insulin sensitivity in T1DM difficult. As hyperinsulinemic-euglycemic clamp studies are cumbersome and invasive, the use of prediction equations for calculating estimated insulin sensitivity may prove to be useful. Along with intensive insulin therapy, dietary modifications and increasing physical activity, the role of Metformin in managing IR in T1DM is becoming increasingly popular. Metformin adjunct therapy in T1DM has been shown to improve insulin sensitivity, glycemic control, lipid profile, body composition, vascular smooth muscle function, thereby reducing the risk of vascular complications, as well as reversal of early vascular dysfunction. However, further studies to assess long-term efficacy and safety of Metformin use in adolescents and youth with T1DM are needed. This review aims at revisiting the pathophysiology of IR in T1DM and techniques of identifying those at risk so as to put into action various strategies for management of the same.

Abstract
Introduction Diabetic retinopathy (DR) is a severe complication of diabetes. It remains a major cause of visual impairment and blindness, especially in young people. It is a silent affection that only becomes symptomatic at the onset of complications. Our study aimed to estimate the prevalence of retinopathy in patients with type 1 diabetes mellitus (T1DM) and evaluate the associated risk factors in our population. Materials and methods A descriptive and analytical study, with a cross-sectional study involving 359 patients with type 1 diabetes, was followed up in the Department of Endocrinology, Diabetology, and Nutrition of the University Hospital Center Mohammed VI Oujda, Morocco. Data were collected from medical records and analyzed by binary logistic regression using IBM Corp. Released 2012. IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp. Results The average age of our patients was 24.2 ± 11.4 years. The mean duration of diabetes was 11.8±4.4 years. The average glycated hemoglobin (HbA1c) at admission was 10.1 ± 2.4%. DR was found in 30% of patients, including 28.6% with minimal non-proliferative diabetic retinopathy (NPDR), 19.1% with moderate NPDR, 19.1% with severe NPDR, and 33.3% with proliferative DR. Patients with diabetic retinopathy appear to have a longer duration of diabetes (13.05±9.05 vs. 10.6±8.07 years). The longer duration of diabetes, neuropathy, and nephropathy was significantly associated with diabetic retinopathy (p=0.02, p=0.002, and p=0.0001, respectively). Conclusion The frequency of diabetic retinopathy increases with age, poor glycemic control, and the duration of diabetes. Therefore, cooperation between diabetologists and ophthalmologists is essential for making an early diagnosis and providing early treatment.

Abstract
INTRODUCTION Our aim was to determine whether there are risk factors which increase the risk of developing dysglycemia in a child who has increased body mass index (BMI) (overweight/obese). RESEARCH DESIGN AND METHODS This was a retrospective cohort study of 715 children who had increased BMI (overweight/obese). They presented to tertiary care at KK Women's and Children's Hospital, Singapore, for metabolic risk assessment. Subjects who had more than one oral glucose tolerance test were included in order to track and analyze risk factors associated with worsening glycemic status from a previously normal glucose tolerance, impaired fasting glucose, or impaired glucose tolerance (IGT) state. Demographic characteristics, birth history, family history of metabolic syndrome, metabolic comorbidities, and interventions received were recorded. Statistical analysis was performed to determine odds ratio (OR) of worsening glycemic status progression in association with an analyzed variable, adjusted for intervention received. RESULTS Risk factors of developing dysglycemia can be present right from birth, as participants who were born preterm had increased odds of IGT (OR: 3.49 (1.10 to 11.03)), and a greater proportion of large-for-gestational-age (LGA)/small-for-gestational-age (SGA) babies had dysglycemia (SGA-IGT: 8.8%, SGA-diabetes mellitus (DM): 5.9%, LGA-IGT: 10.6%, LGA-DM: 11.8%) even at baseline. Being born preterm (OR: 3.49 (1.10 to 11.03)), with comorbidities of hypertension (OR: 1.61 (1.01 to 2.57)), hyperlipidemia (OR: 1.80 (1.19 to 2.72)), and fatty liver disease (OR: 2.08 (1.39 to 3.13)), was significantly associated with an increased OR of developing IGT. Risk factors for developing a worsening glycemic status, either to IGT or DM, included age >10 years (OR 4.94 (1.21 to 20.25)), BMI rise (OR 1.71 (1.17 to 2.49)), BMI increase >1.08 kg/m2 (OR 1.71 (1.16 to 2.51)), comorbidities of hyperlipidemia (OR 1.67 (1.12 to 2.50)), and fatty liver disease (OR 2.11 (1.43 to 3.12)). CONCLUSIONS A child who has increased BMI (overweight/obese) and possesses risk factors for worsening glycemic status, if intervened with routine lifestyle modification advice, may still have increased risk of developing dysglycemia and type 2 DM. Therefore, understanding their risk profile provides opportunities to have a tiered and individualized approach.

Abstract
Diabetes mellitus (DM) is a chronic disease at all ages including childhood and puberty. Failure to treat DM can cause retinopathy, nephropathy and neuropathy. Endocrine and metabolic changes during the pubertal period complicate management of DM. Noopept is a cognitive enhancer that exhibits antidiabetic properties. We investigated the effect of noopept on the histopathology of the cornea, retina, kidney and pancreas in pubertal diabetic rats. We allocated 60 prepubertal male rats randomly into six groups of 10: untreated control (C), DM control (DC), noopept control (NC), DM + noopept (D + N), DM + insulin (D + I) and DM + insulin + noopept (D + I + N). DM was induced by streptozotocin in the DC, D + N, D + I and D + I + N groups. Noopept was administered to the NC, D + N and D + I + N groups; insulin was administered to the D + I and D + I + N groups for 14 days. On day 18 of the experiment, animals were sacrificed and eyes, kidneys and pancreata were excised for histological investigation. Renal tubule diameter and corneal and retinal thickness were increased significantly in DC groups compared to the control group. The D + I, D + N and D + I + N groups exhibited fewer DM induced pathological changes than the DC group. The D + I + N group exhibited no significant differences in renal tubule diameter and corneal and retinal thickness compared to the DC group. Our findings suggest that noopept is protective against DM end organ complications in streptozotocin induced diabetic pubertal rats.

Abstract
AIMS To evaluate clinical outcomes, functional vision and quality of life (QoL) after 35-year duration of type 1 diabetes (T1D) and proliferative diabetic retinopathy (PDR). METHODS A population-based cohort study of T1D. Data from laboratory tests, ophthalmic examinations, multifunctional vision-test, and 15D-QoL measurements were analysed. RESULTS 35 % of the original cohort (n = 216) had PDR, and 48 % of them were re-evaluated. They were 41 ± 3 [34-46] years old and 62 % were males. The duration of T1D was 35 ± 4 [29-41] years. 76 % had transdermal glucose monitoring. HbA1c had decreased from 80.1 mmol/mol to 63.6 mmol/mol (p < 0.001). Visual acuity was 73-77 ETDRS-letters. Two patients had visual impairment. Visual field sensitivities were lower in PDR vs. healthy controls (23.2 ± 3.9 dB vs. 26.9 ± 1.0 dB, and 14.9 ± 5.6 dB vs. 21.0 ± 2.0 dB, respectively, p < 0.001). Contrast sensitivity was similar, but the reaction time was longer in the PDR group (490.5 ms vs. 462.8 ms, p = 0.004). QoL-parameters concerning sleeping, usual activities, discomfort and symptoms, and sexual activity had decreased, but improved for mobility and distress. CONCLUSIONS Long-term visual prognosis and QoL remained good despite the declined functional vision caused by PDR.

Abstract
INTRODUCTION Type 1 diabetes mellitus (T1D) is a chronic disease leading to cardiovascular complications that can be diagnosed early as subclinical vascular damage. To prevent such damage, it is important to increase knowledge of the effects of the different cardiovascular risk factors in patients with T1D. The aim of our study was to assess possible associations between markers of subclinical arterial damage and traditional cardiovascular risk factors, with a special focus on peripheral blood pressure and central blood pressure (cBP), in a sample of young adults with T1D. PATIENTS AND METHODS The study included 172 T1D patients (mean age 24.7 ± 8.7 years, duration of T1D 13.5 ± 9.6 years). Pulse wave velocity (PWV), pulse wave analysis and cBP were assessed by tonometry (SphygmoCor Xcel). Carotid intima-media thickness (cIMT) and carotid distensibility coefficient (cDC) were assessed by high-resolution echo-Doppler analysis and further examined with dedicated hardware. RESULTS Seventeen patients (10.1%) were classified as hypertensive by office peripheral blood pressure, and 48 patients (27.9%) were classified as hypertensive by cBP. One hundred sixteen patients (68.8%) had cDC under the range of normality, one patient had a PWV (0.6%) above 10 m/s, and no patients had a cIMT above 0.9 mm. In multivariable analysis, central SBP, but not metabolic parameters, remained associated with all the markers of subclinical arterial damage [cIMT ( β = 0.288 ± 0.001; P < 0.001), PWV ( β = 0.374 ± 0.007; P < 0.001), cDC ( β = -0.149 ± 0.055; P = 0.029)]. CONCLUSION The independent association between cBP and markers of subclinical vascular damage underlines the importance of haemodynamic factors in the development of early signs of macrovascular disease in T1D patients. Further studies are warranted to better define the role of cBP to stratify cardiovascular risk, to individualize the need for follow-up and to tailor preventive strategies in T1D patients.

Abstract
WHAT IS KNOWN AND OBJECTIVE Diabetic ketoacidosis (DKA) may occur during asparaginase use. However, limited by the study population, the association between asparaginase and DKA has not been elucidated. The purpose of this study was to determine the potential association between asparaginase and DKA and analyse related clinical characteristics and possible risk factor. METHODS Disproportionality analysis with the reporting odd ratio (ROR) was used to detect the adverse reaction signals of asparaginase-associated DKA in Food and Drug Administration Adverse Event Reporting System (FAERS). A literature review was conducted to further analyse clinical characteristics, possible risk factor and something noteworthy in asparaginase-associated DKA. RESULTS AND DISCUSSION A total of 12 reports of DKA associated with l-asparaginase (l-asp) and 6 reports associated with pegaspargase (PEG-asp) were extracted in FAERS, more than 50% of the cases were classified as serious adverse events. DKA was a positive signal of l-asp (ROR = 2.397, 95% CI 1.360-4.226), while not closely related to the use of PEG-asp (ROR = 1.602, 95% CI 0.719-3.570). Searched in PubMed, Embase and Web of Science, a total of eight patients were collected. The patients were mainly adolescent patients, aged between 11 and 25 years old with a median age of 16 years. Drug dosage form distribution is unbalanced, 7 patients received l-asp and only 1 received PEG-asp. WHAT IS NEW AND CONCLUSIONS The ROR of KDA caused by l-asp was statistically significant, but there was not a statistical association for DKA caused by PEG-asp. Asparaginase dosage form may affect the occurrence of DKA, but further research is needed.

Abstract
AIM To assess the impact of the obesity epidemic on type 2 diabetes (T2D), prediabetes and glycometabolic indices in children and adolescents. METHODS We searched four electronic databases (PubMed, Embase, Cochrane and Web of Science). Cross-sectional or cohort studies that reported on obesity and the prevalence of T2D or prediabetes in children and adolescents were reviewed. The study design, sample size and clinical outcomes were extracted from each study. The prevalence of T2D and prediabetes from the studies were pooled using meta-analysis methods. RESULTS Meta-analysis of 228184 participants showed that the prevalence of T2D was 1.3% (95% confidence interval (CI), 0.6-2.1%) in obese subjects, which was 13 times that in normal weight subjects (0.1%, 95% CI, 0.01-0.2%). The prevalence of prediabetes in obese subjects was 3 times that in normal subjects at 17.0% (13.0-22.0%) vs. 6.0% (0.01-11.0%). Moreover, BMI was positively correlated with the prevalence of T2D, prediabetes and glycometabolic indices in obese children and adolescents. CONCLUSION The pooled results confirm that obesity in children and adolescents leads to statistically significant increases in the prevalence of T2D and prediabetes and in glycometabolic indicator levels.

Abstract
BACKGROUND Diabetic retinopathy (DR) is the driving force of blindness in patients with type 2 diabetes mellitus (T2DM). DR has a high prevalence and lacks effective therapeutic strategies, underscoring the need for early prevention and treatment. Yunnan province, located in the southwest plateau of China, has a high pre-valence of DR and an underdeveloped economy.
AIM To build a clinical prediction model that will enable early prevention and treatment of DR.
METHODS In this cross-sectional study, 1654 Han population with T2DM were divided into groups without (n = 826) and with DR (n = 828) based on fundus photography. The DR group was further subdivided into non-proliferative DR (n = 403) and proliferative DR (n = 425) groups. A univariate analysis and logistic regression analysis were conducted and a clinical decision tree model was constructed.
RESULTS Diabetes duration ≥ 10 years, female sex, standing- or supine systolic blood pressure (SBP) ≥ 140 mmHg, and cholesterol ≥ 6.22 mmol/L were risk factors for DR in logistic regression analysis (odds ratio = 2.118, 1.520, 1.417, 1.881, and 1.591, respectively). A greater severity of chronic kidney disease (CKD) or hemoglobin A 1c increased the risk of DR in patients with T2DM. In the decision tree model, diabetes duration was the primary risk factor affecting the occurrence of DR in patients with T2DM, followed by CKD stage, supine SBP, standing SBP, and body mass index (BMI). DR classification outcomes were obtained by evaluating standing SBP or BMI according to the CKD stage for diabetes duration < 10 years and by evaluating CKD stage according to the supine SBP for diabetes duration ≥ 10 years.
CONCLUSION Based on the simple and intuitive decision tree model constructed in this study, DR classification outcomes were easily obtained by evaluating diabetes duration, CKD stage, supine or standing SBP, and BMI.

Abstract
BACKGROUND Insulin pump therapy is a real breakthrough in managing diabetes Mellitus, particularly in children. It can deliver a tiny amount of insulin and decreases the need for frequent needle injections. It also helps to maintain adequate and optimal glycemic control to reduce the risk of metabolic derangements in different tissues. Children are suitable candidates for pump therapy as they need a more freestyle and proper metabolic control to ensure adequate growth and development. Therefore, children and their caregivers should have proper education and training and understand the proper use of insulin pumps to achieve successful pump therapy. The pump therapy continuously improves to enhance its performance and increase its simulation of the human pancreas. Nonetheless, there is yet a long way to reach the desired goal.
AIM To review discusses the history of pump development, its indications, types, proper use, special conditions that may enface the children and their families while using the pump, its general care, and its advantages and disadvantages.
METHODS We conducted comprehensive literature searches of electronic databases until June 30, 2022, related to pump therapy in children and published in the English language.
RESULTS We included 118 articles concerned with insulin pumps, 61 were reviews, systemic reviews, and meta-analyses, 47 were primary research studies with strong design, and ten were guidelines.
CONCLUSION The insulin pump provides fewer needles and can provide very tiny insulin doses, a convenient and more flexible way to modify the needed insulin physiologically, like the human pancreas, and can offer adequate and optimal glycemic control to reduce the risk of metabolic derangements in different tissues.

Abstract
Digital health interventions are a promising alternative to face-to-face psychosocial interventions that may improve psychological outcomes in youth with diabetes. Several reviews have explored the efficacy of digital health interventions for adults and youth with some chronic health conditions; however, their efficacy among youth with type 1 diabetes is not known. This systematic review aims to assess digital health interventions targeting both psychological and physical health outcomes in youth with type 1 diabetes as well as to evaluate study quality and efficacy, and provide directions for future research in this area. Relevant studies were identified through searches conducted in MEDLINE, Embase, APA PsycInfo, Scopus, Cochrane Central, and CINAHL Plus up until February 2021. Studies were included if they were randomized; reported at least one psychological outcome that was assessed at ≥2 time points; included a digital health intervention; and were conducted in youth aged 5 to 25 years with type 1 diabetes. The revised Cochrane risk-of-bias (RoB 2) tool was used to assess risk of bias. Of the 5159 articles found, 15 met the inclusion criteria and were included in the review. Self-efficacy improved in 2 of the 3 studies which assessed self-efficacy; however, no consistent improvements were found for other psychological, behavioral, or physical outcomes. All studies showed some risk of bias concerns. More research is needed to make firm conclusions on the efficacy of digital health interventions for youth with diabetes. More specifically, interventions based on psychological theories are needed and studies of higher quality methodologies.

Abstract
OBJECTIVE To assess the point prevalence of peripheral neuropathy (PN) in children with type 1 diabetes mellitus (T1DM) and to determine their predictors. METHODS In this cross-sectional study, children aged 8-18 y with T1DM on insulin therapy for > 2 y and free from acute complications were enrolled. All participants were evaluated for symptoms of PN with diabetic neuropathy symptom (DNS) score and underwent a detailed neurological examination. Assessment of nerve dysfunction was done using nerve conduction studies (NCS). The disease-related factors that increase the risk of PN were determined. RESULTS Fifty children (52% boys) were enrolled with mean age of 12.2 ± 2.8 y and duration of diabetes 5.1 ± 2.1 y. No subject had clinical evidence or DNS score suggestive of PN. Twenty-eight (56%) children demonstrated subclinical neuropathy on NCS. Proportion of children with pure motor, pure sensory, and mixed motor-sensory neuropathy was 40%, 2%, and 14%, respectively. The peroneal nerve was the most common motor nerve affected. Poor glycemic control (HbA1c > 9%) and longer duration of diabetes (> 5 y) were significantly associated with the risk of PN (p value < 0.05). CONCLUSION A large proportion of children with T1DM have subclinical PN. Poor glycemic control and longer duration of diabetes are risk factors for nerve dysfunction. Neurophysiological studies should be performed in these children to facilitate early detection.

HbA1c percentiles and the association between BMI, age, gender, puberty, and HbA1c levels in healthy German children and adolescents. Pediatr Diabetes 2022; 23:194-202. [PMID: 34877761 DOI: 10.1111/pedi.13297] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 10/12/2021] [Accepted: 11/24/2021] [Indexed: 11/29/2022] Open
Abstract
OBJECTIVE The measurement of glycated hemoglobin (HbA1c) represents one way to detect type 1 and 2 diabetes in children at an early stage. However, to date, variations in HbA1c levels are not fully understood, even in healthy children. With this in mind, the present study aimed to establish HbA1c reference values in healthy children and to investigate the influence of various independent variables. STUDY DESIGN AND METHODS Two thousand four hundred fifty-five healthy children and adolescents aged between 0.5 and 18 years participated in the population-based cohort study LIFE Child, Germany. Age- and gender-dependent percentiles were estimated, enabling HbA1c values to be converted into standard deviation scores (SDS). Logistic regression models were applied to assess associations between HbA1c-SDS (as outcome) and age, gender, BMI, birth weight, physical activity, pubertal status, and socioeconomic status (SES; as explanatory variables). RESULTS The mean HbA1c value was 31.79 mmol/mol or 5.06% (SD = 3.3 mmol/mol, SD = 0.3%). Positive associations with HbA1c values were identified for age (b = 0.09, p < 0.001), gender (b = 0.25, p = 0.007), and BMI-SDS (b = 0.06, p < 0.001). In addition, obesity was related to higher HbA1c values (b = 0.29, p < 0.001). Compared to prepuberty, the pubertal and postpubertal stages were associated with higher HbA1c levels. Furthermore, higher SES was associated with higher HbA1c-SDS (b = 0.01, p = 0.04). CONCLUSION The present study established HbA1c reference values based on a large sample of healthy German children and adolescents. Age, gender, SES, pubertal stage, and BMI were found to be associated with higher HbA1c levels.

Abstract
OBJECTIVE To analyze the trends in disease burden of diabetes-related chronic kidney disease (CKD) by year, age, gender and types of diabetes in China from 1990 to 2019. METHODS Data on prevalence, deaths and disability-adjusted life years (DALYs) for diabetes-related CKD were extracted from the Global Burden of Disease (GBD) 2019 study. Analyses were performed by year, age, gender and types of diabetes. RESULTS In China, the numbers of deaths and DALYs of diabetes-related CKD continuously increased but the age-standardized rates (per 100,000 population) decreased over 30 years, in which the numbers of deaths and DALYs attributable to type 1 diabetes mellitus (T1DM)-related CKD barely changed and the age-standardized rates decreased over the years; and the number of deaths and DALYs attributable to type 2 diabetes mellitus (T2DM)-related CKD continuously increased, but the age-standardized rates also decreased. In 2019, 76.03 (58.24-95.61) thousand deaths and 2.13 (1.65-2.67) million DALYs were attributable to diabetes-related CKD, of which, T2DM accounted for 83.32% and 77.0% respectively, and T1DM accounted for the rest. Increasing gender disparity was seen, with males being more heavily impacted. The burden of diabetes-related CKD varied among different age groups, with the numbers of deaths and DALYs attributable to T1DM-related CKD peaking between 45 and 54 years of age and T2DM-related CKD peaking between 75 and 79 years of age; and the crude rates of deaths and DALYs attributable to T1DM-related CKD peaking between 70 and 79 years of age and 40 to 54 years of age, respectively, and T2DM-related CKD peaking over 90 years of age. Among neighboring and G20 countries, the burden of diabetes-related CKD in China was relatively controlled reflected by the ranking of adjusted death and DALYs rates. CONCLUSIONS The burden of diabetes-related CKD in China worsens and shows gender disparities and different age distribution. Greater efforts are needed to improve the health outcomes of these patients, especially among males.

Abstract
The prevalence of youth-onset diabetes is progressing rapidly worldwide, and poor glycemic control, in combination with prolonged diabetes duration and comorbidities including hypertension, has led to the early development of microvascular complications including diabetic kidney disease, retinopathy, and neuropathy. Pediatric populations with type 1 (T1D) and type 2 (T2D) diabetes are classically underdiagnosed with microvascular complications, and this leads to both undertreatment and insufficient attention to the mitigation of risk factors that could help attenuate further progression of complications and decrease the likelihood for long-term morbidity and mortality. This narrative review aims to present a comprehensive summary of the epidemiology, risk factors, symptoms, screening practices, and treatment options, including future opportunities for treatment advancement, for microvascular complications in youth with T1D and T2D. We seek to uniquely focus on the inherent challenges of managing pediatric populations with diabetes and discuss the similarities and differences between microvascular complications in T1D and T2D, while presenting a strong emphasis on the importance of early identification of at-risk youth. Further investigation of possible treatment mechanisms for microvascular complications in youth with T1D and T2D through dedicated pediatric outcome trials is necessary to target the brief window where early pathological vascular changes may be significantly attenuated.

Abstract
Having diabetes and comorbid chronic physical illnesses (CCPIs) suggests a higher risk for depression and lower health-related quality of life and treatment adherence. Caring for these patients is often overwhelming. Although CCPIs affect youths with type 1 diabetes (T1D), no study has examined the psychosocial or health-related impact of CCPIs in this population. We examined individual, caregiver, and family functioning differences among T1D adolescents with (G1; n = 25) and without (G2; n = 26) CCPIs. Participants were 51 youth (aged 12-17 years) enrolled in a depression treatment study. We administered diagnostic interviews and rating scales to assess each domain of interest. Using MANOVA, followed by individual univariate analyses, and Chi-square tests, we compared groups in continuous and categorical variables, respectively. MANOVA results were significant, F(4, 46) = 2.62, p = .047. Participants from G1 obtained lower global functioning scores compared to G2. Caregivers whose offspring had CCPIs were more depressed and reported higher burden but lower family functioning scores than their counterparts did. A higher percent of youths with CCPIs needed reminders about insulin use and met the criteria for major depression, but a lower proportion had access to insulin pumps. Taking care of youths from G1 was associated with a lifetime history of depressive disorder or suicidality. Our findings support the existence of individual, caregiver, and family functioning differences between T1D adolescents with vs. without CCPIs. Psychosocial interventions should consider the incremental burden that CCPIs may pose over these youth and their families.

Abstract
PURPOSE OF REVIEW Diabetic retinopathy (DR) is a microvascular complication of diabetes mellitus and a major cause of vision loss worldwide. The purpose of this review is to provide an update on the prevalence of diabetic retinopathy in youth, discuss risk factors, and review recent advances in diabetic retinopathy screening. RECENT FINDINGS While DR has long been considered a microvascular complication, recent data suggests that retinal neurodegeneration may precede the vascular changes associated with DR. The prevalence of DR has decreased in type 1 diabetes (T1D) patients following the results of the Diabetes Control and Complications Trial and implementation of intensive insulin therapy, with prevalence ranging from 14-20% before the year 2000 to 3.7-6% after 2000. In contrast, the prevalence of diabetic retinopathy in pediatric type 2 diabetes (T2D) is higher, ranging from 9.1-50%. Risk factors for diabetic retinopathy are well established and include glycemic control, diabetes duration, hypertension, and hyperlipidemia, whereas diabetes technology use including insulin pumps and continuous glucose monitors has been shown to have protective effects. Screening for DR is recommended for youth with T1D once they are aged ≥ 11 years or puberty has started and diabetes duration of 3-5 years. Pediatric T2D patients are advised to undergo screening at or soon after diagnosis, and annually thereafter, due to the insidious nature of T2D. Recent advances in DR screening methods including point of care and artificial intelligence technology have increased access to DR screening, while being cost-saving to patients and cost-effective to healthcare systems. While the prevalence of diabetic retinopathy in youth with T1D has been declining over the last few decades, there has been a significant increase in the prevalence of DR in youth with T2D. Improving access to diabetic retinopathy screening using novel screening methods may help improve detection and early treatment of diabetic retinopathy.

Abstract
Development of complications in type 1 diabetes patients can be reduced by modifying risk factors. We used a cross-sectional cohort of 1646 patients diagnosed with type 1 diabetes (T1D) to develop a clinical risk score for diabetic peripheral neuropathy (DPN), autonomic neuropathy (AN), retinopathy (DR), and nephropathy (DN). Of these patients, 199 (12.1%) had DPN, 63 (3.8%) had AN, 244 (14.9%) had DR, and 88 (5.4%) had DN. We selected five variables to include in each of the four microvascular complications risk models: age, age of T1D diagnosis, duration of T1D, and average systolic blood pressure and HbA1C over the last three clinic visits. These variables were selected for their strong evidence of association with diabetic complications in the literature and because they are modifiable risk factors. We found the optimism-corrected R2 and Harrell’s C statistic were 0.39 and 0.87 for DPN, 0.24 and 0.86 for AN, 0.49 and 0.91 for DR, and 0.22 and 0.83 for DN, respectively. This tool was built to help inform patients of their current risk of microvascular complications and to motivate patients to control their HbA1c and systolic blood pressure in order to reduce their risk of these complications.

Abstract
To assess choroidal thickness (CT) in children with type 1diabetes (T1D) regarding their pubertal status and seek for factors influencing this parameter, using optical coherence tomography. MATERIAL AND METHODS 333 eyes out of 167 children with T1D without symptoms of diabetic retinopathy (mean age 12.81 ± 3.63 years, diabetes duration 4.59 ± 3.71 years) were enrolled. CT in all quadrants was evaluated. The studied population was divided into three groups: prepubertal, pubertal and postpubertal. The multivariate regression model was carried out using all metabolic parameter and then it was built using only the significant ones. RESULTS Significant differences in CT between males and females, except nasal and superior quadrants were observed. We revealed significant differences in CT between the three independent groups (Chi-square 18.6, p < 0.0001). In the statistically significant multiple regression model (R = 0.9, R2 = 0.82, p < 0.0000), the serum level of free thyroxine, triiodothyronine, total hemoglobin, uric acid, low- and high-density cholesterol, daily insulin dose per kilogram, weight and level of vitamin D were significant. CONCLUSION In our studied group CT increases during puberty. Metabolic parameters such as cholesterol, uric acid, thyroid hormones, and hemoglobin concentration even within the normal range, significantly influence the CT, and these factors likely affect other blood vessels in the body.

Abstract
Long-term complications of type 1 diabetes (T1D) include microvascular complications and macrovascular disease. Despite the important advances in the treatment of T1D of the last decades, these complications still represent the leading cause of morbidity and mortality in patients with T1D. Extensive evidence indicates that structural and functional alterations of the kidney, retina, nerves and large arteries occur already in the first years after the onset of diabetes. We performed a comprehensive review of the available evidence on screening, diagnosis, prevention and treatment of vascular complications of T1D. In particular, we focused on three major challenges related to long-term complications of T1D: 1) finding of new biomarkers and diagnostic methods able to identify early signs of complications; 2) identifying specific risk factors for the development of these complications; 3) identifying and implementing new therapeutic strategies able to prevent the development and progression of vascular complications.

Abstract
AIM To determine advantages conferred by a youth-specific transition clinic model for young adults with type 1 diabetes (T1D) at Westmead Hospital (WH) as compared with Australian registry data. METHODS Prospectively collected data included age, diabetes duration, visit frequency, post code, BMI, mode of insulin delivery, continuous glucose monitoring, HbA1c, albumin creatinine ratio, BP, retinopathy and diabetic ketoacidosis (DKA) for all WH T1D clinic attendees aged 16-25 between January 2017 and June 2018 (n = 269). Results were compared with data collected during the same time period from 2 separate Australian data registries, one longitudinal (Australasian Diabetes Data Network, ADDN) and one a spot survey (the Australian National Diabetes Audit, ANDA). RESULTS Across the three cohorts, HbA1c was similar (respectively, WH, ADDN, ANDA; 8.7%[72mmol/mol], 8.7%[72mmol/mol], 8.5%[69mmol/mol]) and HbA1c was significantly higher in young adults <21 years (8.7-8.9%[73-75mmol/mol]) as compared with ≥21 years (8.5%[69mmol/mol], p < .002). In the WH cohort, median interval between visits was shorter than in ADDN (4.5 vs. 9.0 months) and DKA was lower (respectively, 3.6 and 9.2/100 patient years; p < .001). CONCLUSIONS While suboptimal HbA1c was recorded in all centres, the WH model of care saw increased attendance and reduced admissions with DKA as compared with other Australian adult centres.

Diabetol Metab Syndr 2021; 13:79. [PMID: 34294136 PMCID: PMC8296697 DOI: 10.1186/s13098-021-00699-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Accepted: 07/09/2021] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Several studies have demonstrated suppressed levels of acylated (AG) and unacylated ghrelin (UAG) in patients with type 2 diabetes. However, the role of these hormones in type 1 diabetes has not been extensively studied. This study assessed the relationship between AG and UAG levels and body composition in patients with type 1 diabetes. METHODS We selected eighteen patients with type 1 diabetes and divided them into two groups: non-obese (BMI < 25 kg/m2) and overweight (BMI ≥ 25 kg/m2). Demographics, parameters of body composition and serum parameters including AG and UAG, were assessed. RESULTS The patients with a BMI ≥ 25 kg/m2 were older and had a longer duration of diabetes. AG and UAG levels were not significantly different between non-obese and overweight groups (mean AG non-obese ± SD: 44.5 ± 29.4 pg/ml and mean UAG non-obese 42.4 ± 20.7 pg/ml vs mean AG overweight ± SD: 46.1 ± 29.6 pg/ml and mean UAG overweight 47.2 ± 18.2 pg/ml). AG/UAG ratios did not discriminate between these groups. There was a positive association of insuline dose/kg bodyweight with BMI (r2 = 0.45, p = 0.002). CONCLUSIONS Surprisingly, unlike non-diabetics and in T2D, we did not observe a difference in plasma levels of AG and UAG between normal weight and overweight adult type 1 diabetics. However, we did observe a positive correlation between BMI and insuline dose/kg bodyweight, suggesting that exogenous insulin is more important than the ghrelin system in the development of obesity in type 1 diabetes.

Abstract
PURPOSE To describe the occurrence of diabetic retinopathy, the principles for pediatric care of patients with diabetes, and the utility of optical coherence tomography. Pediatric patients with type 1 diabetes should be screened for diabetic retinopathy upon the lapse of 5 years following the diagnosis. The patients in the time of puberty, who should be screened promptly after the diabetes diagnosis, and patients with type 2 diabetes are the exceptions. Special attention must be paid not only to retinopathy, but also to other possible concomitant conditions, such as cataract, refractive errors, or neuropathy. New techniques, such as optical coherence tomography angiography (OCTA), may contribute greatly to the early detection of retinopathy, facilitating the decision to modify the treatment. The application of modern insulin pumps with continuous glucose monitoring systems has greatly diminished the incidence rate of early symptoms of diabetic retinopathy in the pediatric population.

Abstract
The incidence and prevalence rate of chronic inflammatory disorders is on the rise in the pediatric population. Recent research indicates the crucial role of interactions between the altered intestinal microbiome and the immune system in the pathogenesis of several chronic inflammatory disorders in children, such as inflammatory bowel disease (IBD) and autoimmune diseases, such as type 1 diabetes mellitus (T1DM) and celiac disease (CeD). Here, we review recent knowledge concerning the pathogenic mechanisms underlying these disorders, and summarize the facts suggesting that the initiation and progression of IBD, T1DM, and CeD can be partially attributed to disturbances in the patterns of composition and abundance of the gut microbiota. The standard available therapies for chronic inflammatory disorders in children largely aim to treat symptoms. Although constant efforts are being made to maximize the quality of life for children in the long-term, sustained improvements are still difficult to achieve. Additional challenges are the changing physiology associated with growth and development of children, a population that is particularly susceptible to medication-related adverse effects. In this review, we explore new promising therapeutic approaches aimed at modulation of either gut microbiota or the activity of the immune system to induce a long-lasting remission of chronic inflammatory disorders. Recent preclinical studies and clinical trials have evaluated new approaches, for instance the adoptive transfer of immune cells, with genetically engineered regulatory T cells expressing antigen-specific chimeric antigen receptors. These approaches have revolutionized cancer treatments and have the potential for the protection of high-risk children from developing autoimmune diseases and effective management of inflammatory disorders. The review also focuses on the findings of studies that indicate that the responses to a variety of immunotherapies can be enhanced by strategic manipulation of gut microbiota, thus emphasizing on the importance of proper interaction between the gut microbiota and immune system for sustained health benefits and improvement of the quality of life of pediatric patients.

Abstract
Aim To evaluate dependence of abnormalities in peripheral nerves and retina in children with type 1 diabetes (T1D) using optical coherence tomography angiography (OCTA) and nerve conduction studies (NCS). Material and methods 50 adolescents with T1D without any signs and symptoms of diabetic retinopathy and neuropathy (mean age 16.92±1.6 years, diabetes duration 6.88 ±4.34years) were included. In OCTA capillary plexuses superficial (SCP) and deep (DCP) vessel density: whole, foveal and parafoveal, ganglion cell complex (GCC), loss volume focal (FLV) and global loss volume (GLV) were analyzed in relation to NCS parameters (motor nerves median and tibial potential amplitude (CMAP), velocity (CV), distal latency (DML) and F wave and sensory nerves median and sural potential amplitude (SNAP), CV and distal latency (DSL). Results We detected the correlations between median sensory SNAP and GCC (r = -0.3, p <0.04), motor nerves tibial DML and CV and FLV (respectively r = -0.53, p<0.001, and r = -0.34, p<0.05), and median DML and GLV (r = 0.47, p<0.001). Vessel densities were related to changes in motor nerves tibial velocity (whole SCP r = 0.43, p <0.01, parafoveal SCP r = 0.41, p <0.01), CMAP (parafoveal SCP r = -0.35, p<0.03), median DML (whole DC r = 0.36, p<0.03, foveal DCP r = 0.37, p<0.02) and in sensory median SNAP (whole SCP r = -0.31, p<0.05). Conclusions In adolescents with T1D without diabetic neuropathy and retinopathy we detected associations between NCS and OCT and OCTA parameters, regarding decreased GCC and density of superficial and deep vessel plexuses in relation to DML and CV and amplitudes of sensory and motor potential.

Abstract
BACKGROUND This study aimed to assess the influence of pubertal status on the results of optical coherence tomography angiography (OCTA) in children with type 1 diabetes (T1D). METHODS We enrolled 167 consecutive children with T1D. Retinal superficial capillary plexus (SCP) and deep capillary plexus (DCP) vessel density data underwent analysis. We divided the study population into three subgroups depending on the pubertal status. RESULTS Analysis of the prepubertal and pubertal subgroups revealed statistically significant differences in foveal thickness (FT) (p < 0.05) and foveal SCP (p < 0.02). Analyzing subgroups of the prepubertal and postpubertal children, we observed statistically significant differences in FT (p < 0.03), whole SCP (p < 0.02), and foveal SCP (p < 0.02). Comparison of the pubertal and postpubertal subjects revealed differences in parafoveal DCP (p < 0.003). In the groups matched depending on diabetes duration, we observed differences between prepubertal, pubertal, and postpubertal children in FT, PFT, and parafoveal SCP and DCP. CONCLUSION Our data suggest that in a cohort of pubertal children with a short duration of diabetes, alterations in retinal vessel density occur early and progress during puberty.

Abstract
Cardiovascular disease (CVD) remains the main cause of morbidity and mortality in individuals with type 1 diabetes (T1D). Adolescence appears to be a critical time for the development of early subclinical manifestations of CVD, with these changes likely driven by a deterioration in glycemic control during the progression through puberty, combined with the emergence of numerous other traditional cardiometabolic risk factors (e.g., hypertension, dyslipidemia, smoking, alcohol use, obesity, etc.) which emerge at this age. Although hemoglobin A1C has long been the primary focus of screening and treatment strategies, glycemic control remains poor in youth with T1D. Furthermore, screening for cardiovascular risk factors-which are often elevated in youth with T1D-is suboptimal, and use of pharmacological interventions for hypertension and dyslipidemia remains low. As such, there is a clear need not only for better screening strategies for CVD risk factors in youth, but also early interventions to reduce these, if future CVD events have to be prevented. Accumulating evidence has recently suggested that early increases in urinary albumin excretion, even within the normal range, may identify adolescents with T1D who are at an increased risk of complications, and results from pharmacological intervention with statins and ACE inhibitors in these individuals have been encouraging. These data join a growing evidence highlighting the need for a whole-life approach to prevention starting from childhood if efforts to improve CVD outcomes and related mortality in T1D are to be maintained.

Abstract
BACKGROUND The aim of this study was to evaluate characteristics and risk of diabetic complications according to age at diagnosis among young adults with type 1 diabetes mellitus (T1DM). METHODS A total of 255 T1DM patients aged less than 40 years were included. Patients were categorized into three groups (<20, 20 to 29, and 30 to 40 years) according to age at diagnosis. Diabetic nephropathy (DN) was defined when spot urine-albumin creatinine ratio was 300 mg/g or more and/or estimated glomerular filtration ratio (eGFR) level was 60 mL/min/1.73 m2 or less. RESULTS Median age at diagnosis was 25 years and disease duration was 14 years. Individuals diagnosed with T1DM at childhood/adolescent (age <20 years) had lower stimulated C-peptide levels. They received more intensive insulin treatment with higher total daily insulin doses compared to older onset groups. The prevalence of DN was higher in the childhood/adolescent-onset group than in older onset groups (25.3% vs. 15.3% vs. 9.6%, P=0.022). The eGFR was inversely associated with disease duration whilst the degree of decrease was more prominent in the childhood/adolescent-onset group than in the later onset group (aged 30 to 40 years; P<0.001). Childhood/adolescent-onset group was independently associated with the risk of DN compared to the older onset group (aged 30 to 40 years; odds ratio, 3.47; 95% confidence interval, 1.45 to 8.33; P=0.005). CONCLUSION In individuals with childhood/adolescent-onset T1DM, the reduction in renal function is more prominent with disease duration. Early age-onset T1DM is an independent risk of DN.

Abstract
Type 1 diabetes (T1D) is mainly a disease of children and young adults. Diabetic nephropathy (DN) is a common finding in diabetic patients. Microalbuminuria is the earliest clinical evidence of DN. Aim of the study was analysis of clinical, laboratory, instrumental, anamnestic examinations data in pediatric patients with T1D and early stage of DN in order to evaluate possible factors associated with early stage of DN and predictors of DN development and progression. A survey of 105 children (62 males, 43 females) with T1D and DN aged 5 to 17 years in Endocrinology unit on Clinical Pediatric Hospital №6 (Kyiv, Ukraine) done. Following clinical and biochemical characteristics found associated with an early DN: inflammatory phenotype (increased ESR, decreased albumin/globulin ratio), functional cardiovascular disorders (increased systolic blood pressure, “minor” ECG changes), signs of secondary metabolic disorders (high HbA1c, increased serum cholesterol level, increase ALAT and ASAT levels). Kidney function impairment at early stage of DN shows: higher MAU grade, GFR decline, rise in serum creatinine level as compared to T1D group. Presence of concomitant kidney and endocrine disease; positive family history found in a bigger number of patients with DN. DKA episodes number found as a factor associated with higher levels of MAU in children with DN. Patients who had microalbuminuria and more than 5 episodes of DKA/year (poorly controlled T1D) have higher progression rate to macroalbuminuria as compared to those who have less than 5 episodes of DKA/year after a 6-year follow-up study.

Abstract
Purpose Optical coherence tomography (OCT) and OCTA were used for qualitative and quantitative assessment of retinal vascular density in superficial capillary plexus, deep capillary plexus, foveal avascular zone, and choroidal vascular density map. Patients and Methods This study included 64 eyes. Diabetics and control groups were recruited from an internal medicine clinic at Misr University for Science and Technology Hospital and asked to participate in this study. This study was designed as an observational and cross-sectional study in the period from 8/2018 to 8/2019. Results There was a decrease in choroidal vascular density in diabetic patients. There was a decrease in retinal thickness in diabetic patients and there were no significant differences in the retinal thickness between control subjects and patients with non-diabetic retinopathy (NDR). Conclusion Our study suggests that OCTA can identify preclinical DR before the manifestation of clinically apparent retinopathy. Our findings also highlight the potential role of OCTA in monitoring and quantifying retinal vascular alterations in diabetics.

Abstract
Purpose: This study aims to assess choroidal vascularity index (CVI) and choroidal thickness (CT) in patients diagnosed with type 1 diabetes mellitus (DM) and compare them with healthy control subjects.Methods: This retrospective and cross-sectional study includes 43 patients diagnosed with type 1 DM and 43 healthy age/gender-matched subjects as the control group. Enhanced depth imaging optical coherence tomography (EDI-OCT; Spectralis, Heidelberg Engineering GmbH, Heidelberg, Germany) images of all participants were analyzed. CT measurements of five different points (subfoveal, 500 µm temporal, 1500 µm temporal, 500 µm nasal, and 1500 µm nasal to the fovea) were obtained. Choroid images were divided into luminal (LA) and stromal areas (SA) determined by image binarization method. Choroidal vascularity index (CVI) was defined as the ratio of LA to total choroid area (TCA). The effects of age, HbA1c, fasting plasma glucose, duration of DM, mean blood pressure, intraocular pressure, and axial length measurements on CVI were investigated.Results: There was no significant difference between any of the CT measurements of the groups (all p > .05). There was no significant difference between the groups according to TCA (0.82 ± 0.24 vs. 0.80 ± 0.19; p = .065), LA (0.54 ± 0.17 vs. 0.55 ± 0.16; p = .123) and SA (0.28 ± 0.06 vs. 0.25 ± 0.07; p = .068). However, patients had significantly lower CVI compared to control subjects (66.07 ± 3.19 vs. 68.89 ± 2.85, p < .001). Univariate linear regression model revealed that there was a negative correlation between disease duration and CVI (standardized beta coefficient: -0.416, p = .006).Conclusion: According to our findings, reduced CVI may indicate subclinical dysfunction in choroid of patients with type 1 DM.

Forrester JV, Kuffova L, Delibegovic M. The Role of Inflammation in Diabetic Retinopathy. Front Immunol 2020; 11:583687. [PMID: 33240272 PMCID: PMC7677305 DOI: 10.3389/fimmu.2020.583687] [Citation(s) in RCA: 151] [Impact Index Per Article: 37.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Accepted: 09/21/2020] [Indexed: 12/14/2022] Open
Abstract
Inflammation is central to pathogenic processes in diabetes mellitus and the metabolic syndrome and particularly implicates innate immunity in the development of complications. Inflammation is a primary event in Type 1 diabetes where infectious (viral) and/or autoimmune processes initiate disease; in contrast, chronic inflammation is typical in Type 2 diabetes and is considered a sequel to increasing insulin resistance and disturbed glucose metabolism. Diabetic retinopathy (DR) is perceived as a vascular and neurodegenerative disease which occurs after some years of poorly controlled diabetes. However, many of the clinical features of DR are late events and reflect the nature of the retinal architecture and its cellular composition. Retinal microvascular disease is, in fact, an early event pathogenetically, induced by low grade, persistent leukocyte activation which causes repeated episodes of capillary occlusion and, progressive, attritional retinal ischemia. The later, overt clinical signs of DR are a consequence of the retinal ischemia. Metabolic dysregulation involving both lipid and glucose metabolism may lead to leukocyte activation. On a molecular level, we have shown that macrophage-restricted protein tyrosine phosphatase 1B (PTP1B) is a key regulator of inflammation in the metabolic syndrome involving insulin resistance and it is possible that PTP1B dysregulation may underlie retinal microvascular disease. We have also shown that adherent CCR5+CD11b+ monocyte macrophages appear to be selectively involved in retinal microvascular occlusion. In this review, we discuss the relationship between early leukocyte activation and the later features of DR, common pathogenetic processes between diabetic microvascular disease and other vascular retinopathies, the mechanisms whereby leukocyte activation is induced in hyperglycemia and dyslipidemia, the signaling mechanisms involved in diabetic microvascular disease, and possible interventions which may prevent these retinopathies. We also address a possible role for adaptive immunity in DR. Although significant improvements in treatment of DR have been made with intravitreal anti-VEGF therapy, a sizeable proportion of patients, particularly with sight-threatening macular edema, fail to respond. Alternative therapies targeting inflammatory processes may offer an advantage.

Abstract
AIMS To determine whether early retinal neurodegenerative changes in pediatric patients with type 1 diabetes (T1D) can be detected by spectral domain-optical coherence tomography (SD-OCT) and whether such changes are associated with risk factors for T1D complications. METHODS A total of 147 T1D children/adolescents and 51 healthy controls underwent SD-OCT. Spherical refractive error (SRE), macular total retinal thickness (TRT), ganglion cell layer (GCL), retinal nerve fiber layer (RNFL), minimum rim width (MRW), and Bruch's membrane opening area (BMOA) were measured. Clinical and biochemical parameters were recorded at the time of SD-OCT and starting at T1D onset. Multiple regression models were calculated using SD-OCT parameters as dependent and risk factors as independent variables. RESULTS MRW was significantly thinner in the T1D patients (global MRW:361.58vs386.33 µm; p = 0.009), while RNFL and macular parameters were similar for both groups. MRW was inversely correlated with mean HbA1c (r ≥ -0.180, p < 0.05). Multiple regression showed that part of the variability in MRW was explained by HbA1c and BMOA (R2 = 0.21; p < 0.001), independent of other cardiometabolic risk factors. CONCLUSIONS MRW reduction could be a potential early marker of retinal neurodegeneration detectable in pediatric patients with T1D. The association between MRW and mean HbA1c suggests that glucometabolic control may affect early retinal neurodegeneration starting in childhood.

Demographic and socioeconomic patterns in the risk of alcohol-related hospital admission in children and young adults with childhood onset type-1 diabetes from a record-linked longitudinal population cohort study in Wales. Pediatr Diabetes 2020; 21:1333-1342. [PMID: 32737911 DOI: 10.1111/pedi.13089] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Revised: 07/18/2020] [Accepted: 07/28/2020] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND Little is known about alcohol-related harm in children and young adults with type 1 diabetes (T1D). Education on managing alcohol intake is provided to teenagers with T1D in paediatric clinics in Wales, but its effectiveness is unknown. We compared the patterns in risk of alcohol-related hospital admissions (ARHA) between individuals with and without childhood-onset T1D. METHODS We extracted data for 1 791 577 individuals born during 1979 to 2014 with a general practitioner registration in Wales, and record-linked the demographic data to ARHA between 1998 and June 2016 within the Secure Anonymised Information Linkage Databank (SAIL). Linkage to a national T1D register (Brecon Cohort) identified 3575 children diagnosed aged <15 years since 1995. We estimated hazard ratios (HRs) with 95% confidence intervals (95% CIs) for the risk of ARHA using recurrent-event models, including interaction terms. RESULTS Individuals with T1D had a higher riskof ARHA (HR: 1.78; 95% CI: 1.60-1.98), adjusted for age group, sex, and deprivation. The risk in people with diabetes was highest aged 14 to 17 years, around three times higher than the peak in non-T1D aged 18 to 22. Females with diabetes had a lower risk generally. The association between deprivation and ARHA was weaker in the T1D group. CONCLUSION Young people with T1D had increased risks of ARHA, particularly at school age, and smaller socioeconomic inequalities in ARHA. A review of interventions to reduce alcohol-related harm in T1D is needed, perhaps including modification of current education and guidance for teenagers on managing alcohol consumption and reviewing criteria for hospital admission.

Abstract
An increased albumin-creatinine ratio within the normal range can identify adolescents at higher risk of developing adverse cardio-renal outcomes as they progress into adulthood. Utilizing a parallel randomized controlled trial and observational cohort study, we characterized the progression of vascular phenotypes throughout this important period and investigated the effect of ACE (angiotensin-converting enzyme) inhibitors and statins in high-risk adolescents. Endothelial function (flow-mediated dilation and reactive hyperemia index) and arterial stiffness (carotid-femoral pulse wave velocity) were assessed in 158 high-risk participants recruited to a randomized, double-blind placebo-controlled 2×2 factorial trial (randomized, placebo-controlled trial) of ACE inhibitors and/or statins in adolescents with type 1 diabetes (AdDIT [Adolescent Type 1 Diabetes cardio-renal Intervention Trial]). Identical measures were also assessed in 215 lower-risk individuals recruited to a parallel observational study. In the randomized, placebo-controlled trial, high-risk patients randomized to ACE inhibitors had improved flow-mediated dilation after 2 to 4 years of follow-up (mean [95% CI]: 6.6% [6.0-7.2] versus 5.3% [4.7-5.9]; P=0.005), whereas no effect was observed following statin use (6.2% [5.5-6.8] versus 5.8% [5.1-6.4]; P=0.358). In the observational study, patients classed as high-risk based on albumin-creatinine ratio showed evidence of endothelial dysfunction at the end of follow-up (flow-mediated dilation=4.8% [3.8-5.9] versus 6.3% [5.8-6.7] for high-risk versus low-risk groups; P=0.015). Neither reactive hyperemia index nor pulse wave velocity were affected by either treatment (P>0.05 for both), but both were found to increase over the duration of follow-up (0.07 [0.03-0.12]; P=0.001 and 0.5 m/s [0.4-0.6]; P<0.001 for reactive hyperemia index and pulse wave velocity, respectively). ACE inhibitors improve endothelial function in high-risk adolescents as they transition through puberty. The longer-term protective effects of this intervention at this early age remain to be determined. Registration- URL: https://www.clinicaltrials.gov; Unique identifier NCT01581476.

Graefes Arch Clin Exp Ophthalmol 2020; 258:2363-2372.

Abstract
BACKGROUND The aim of the study was to investigate whether retinal neurovascular structural impairment in children and adolescents with type 1 diabetes mellitus (T1D) without clinical signs of diabetic retinopathy (DR) could be detected early via optical coherence tomography (OCT) and OCT angiography (OCTA). METHODS In the current prospective, cross-sectional, observational clinical study children and adolescents with T1D without DR were evaluated between December 2018 and May 2019. Retinal neurovascular structures in the macular and optic disc regions were examined in detail and quantitatively assessed using OCT and OCTA. Data from subjects with T1D were compared with data from healthy controls. Whether retinal neurovascular structural changes were significantly associated with puberty stage, diabetes duration, and HbA1c level was also investigated. RESULTS The T1D group included 110 eyes and the control group included 84 eyes. In the T1D group the mean inside disc vessel density (VD) was significantly lower than that of the control group (p < 0.001), as was the mean superior temporal disc VD (p < 0.043). Puberty stage was significantly associated with retinal thickness, parafoveal superficial capillary plexus VD, and peripapillary retinal nerve fiber layer thickness (p < 0.05). Diabetes duration and HbA1c level was significantly correlated with retinal layer thickness, foveal avascular zone diameter, and superficial and deep capillary plexus VDs. CONCLUSION In children and adolescents with T1D without clinical signs of DR, the VD of the disc region is affected earlier than the macular region. In these patients, early neurovascular impairment can be detected non-invasively via OCT and OCTA.

Abstract
The World Health Organization has defined Diabetes mellitus as a disorder of metabolism of various causes, due to lack of secretion and / or action of insulin, with long-term hyperglycemia and altered metabolism of sugars, proteins and fats. Diabetes mellitus is the most widespread chronic non-infectious disease, with an increase in the frequency in childhood that could be the epidemic of the 21st century. The incidence is rapidly increasing in the world, while in the last thirty years in Serbia there has been an increase in the number of patients - especially in the group of small and preschool children. Exposure to the genetic, immune and environmental factors plays an important role in the etiology of the disease, but the underlying mechanisms remain unknown. Weeks before the final diagnosis, weakness, irresistible hunger, weight loss, increased thirst, pronounced diuresis, drying of the mucous membranes, skin pruritus and blurred vision could be present. Inadequate glycemic control and unregulated lipid status of children with type 1 diabetes are compatible with numerous complications and a higher risk of cardiovascular, peripheral vascular and cerebrovascular diseases. The therapy consists of insulin therapy, adequate daily physical activity, a variety of diets, overcoming stressful life situations and maintaining satisfactory metabolic control. By using intensive insulin therapy, the best control of the disease is achieved, while the frequency of possible complications is reduced.

Abstract
AIM To evaluate the influence of metabolic parameters and the treatment method in children with type 1 diabetes (T1D) on the optical coherence tomography angiography (OCTA) results as early markers of diabetic retinopathy (DR). Material and Methods. This prospective study enrolled 175 consecutive children with T1D. OCTA was performed using AngioVue (Avanti, Optovue). Whole superficial capillary vessel density (wsVD), fovea superficial vessel density (fsVD), parafovea superficial vessel density (psVD), whole deep vessel density (wdVD), fovea deep vessel density (fdVD), parafovea deep vessel density (pdVD), foveal thickness (FT), parafoveal thickness (PFT), and foveal avascular zone (FAZ) in superficial plexus were evaluated and analyzed in relation to individual characteristics, i.e., sex, weight, height, body mass index (BMI), and metabolic factors: current and mean value of glycated hemoglobin A1c (HbA1c). Furthermore, the analysis concerned the diabetes duration, age at the T1D onset, and type of treatment-multiple daily insulin injections (MDI) or continuous subcutaneous insulin infusion (CSII). RESULTS In the study group, we did not identify any patient with DR in fundus ophthalmoscopy. Age at the onset of diabetes correlated negatively with FAZ (r = -0.17, p < 0.05). The higher level of HbA1c corresponded to a decrease of wsVD (r = -0.13, p < 0.05). We found significantly lower fsVD (32.25 ± .1 vs. 33.98 ± .1, p < 0.01), wdVD (57.87 ± .1 vs. 58.64 ± .9, p < 0.01), and pdVD (60.60 ± .2 vs. 61.49 ± .1, p < 0.01) and larger FAZ area (0.25 ± .1 vs. 0.23 ± .1, p < 0.05) in the CSII vs. MDI group. CONCLUSION The metabolic parameters, age of the onset of diabetes, and treatment method affected the OCTA results in children with T1D. Further studies and observation of these young patients are needed to determine if these findings are important for early detection of DR or predictive of future DR severity.

Abstract
ABSTRACT Objective: to analyze the trend of hospitalization rates and mortality due to Diabetes Mellitus in children and adolescents in Brazil. Method: temporal series study, hospitalization rates and diabetes mortality in children and adolescents. Data were obtained from the Hospital Information System and Mortality Information System, from 2005-2015, with analysis performed by polynomial regression modeling. Results: 87,100 hospitalizations and 1,120 deaths from diabetes were analyzed. Hospitalizations rates increased for both genders and all age groups, with an increase for adolescents aged 10-14 years. The mortality rate declined, except for the 15-19-year age group. In the overall mortality trend in Brazil, the South and Southeast showed a decrease, whereas for hospitalizations only the Center-West remained constant, while the others increased. Conclusion: however, there was a decrease in infant mortality and increase in hospitalizations.

Abstract
AIM To assess the association between alcohol consumption and/or cigarette smoking with other unhealthy behaviors and clinical cardiovascular risk factors in youth with type 1 diabetes. METHODS Two hundred and twenty-eight youth with type 1 diabetes (age 13-19 years) were consecutively enrolled in three Regional Pediatric Diabetes Centers in Italy. Demographic, anthropometric, lifestyle (adherence to the Mediterranean diet pattern and sports participation) and laboratory parameters were compared among youth reporting isolated or combined alcohol consumption and/or cigarette smoking. RESULTS Ten percent of the youth reported alcohol consumption, 10% cigarette smoking and 6% both alcohol and cigarette use; 74% did not report alcohol or cigarette use. Compared to non-drinker non-smoker youth, smokers showed significantly higher percentages of each of the behavioral and clinical cardiovascular risk factors. Drinkers showed a significantly higher proportion of abdominal adiposity, dyslipidemia and poor adherence to the Mediterranean diet. Alcohol consumption was independently associated with both dyslipidemia and high glycosylated hemoglobin. CONCLUSIONS Our findings emphasize the need to increase the awareness of youth with T1D about the negative impact of alcohol drinking on cardiovascular risk, since the effects of alcohol might be underestimated with respect to the well-known detrimental effects of smoking. Clustering of unhealthy lifestyle should be discouraged in type 1 diabetes youth in order to promote cardiovascular protection.

Abstract
BACKGROUND Inflammation is implicated in the pathogenesis of diabetes and its complications in adults. Little is known about the relative contribution of inflammation in common types of diabetes in youth: type 1 diabetes (T1D), type 2 diabetes (T2D), and cystic fibrosis-related diabetes (CFRD). This study investigates inflammatory markers by diabetes type and complication status, and assesses indicators of inflammation and complications. METHODS A cross-sectional study of 134 T1D, 32 T2D, 32 CFRD and 48 subjects without diabetes (including 11 with CF and normal glucose tolerance) was undertaken. Inflammation was assessed by sE-selectin by ELISA, hsCRP by turbidimetry, WCC and ESR. Nephropathy was defined by albuminuria, autonomic neuropathy by heart rate variability, and peripheral neuropathy by vibration and thermal threshold testing and retinopathy by seven-field stereoscopic fundus photography. Descriptive statistics, parametric and non-parametric ANOVA and regression analyses were performed, with significance at P < .05. RESULTS Of 198 diabetic participants; 49% female, mean (SD) age, median diabetes duration and median HbA1c were 16 (2.5) and 6 (3-9) years, and 8.1 (6.9-9.3)%, respectively. All inflammatory markers were lower in T1D than in other diabetes groups (P < .05) but higher than in non-diabetic controls. T2D (n = 32) and CFRD (n = 32) subjects had comparable elevated levels of inflammation. Body mass index (BMI) was a strong independent explanatory variable of inflammation. In multivariate analysis, hsCRP and ESR were associated with complications in addition to HbA1c, BMI, and diastolic BP. CONCLUSIONS Circulating inflammatory markers are elevated in adolescents with diabetes, being higher and comparable in T2D and CFRD than in T1D. Inflammation is independently associated with diabetes complications, consistent with inflammation driving vascular pathology in diabetes.

Inanc M, Tekin K, Kiziltoprak H, Ozalkak S, Doguizi S, Aycan Z. Changes in Retinal Microcirculation Precede the Clinical Onset of Diabetic Retinopathy in Children With Type 1 Diabetes Mellitus. Am J Ophthalmol 2019; 207:37-44. [PMID: 31009594 DOI: 10.1016/j.ajo.2019.04.011] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2018] [Revised: 03/30/2019] [Accepted: 04/13/2019] [Indexed: 12/29/2022]
Abstract
PURPOSE To investigate whether abnormal glucose metabolism in diabetes mellitus (DM) affects the retinal microcirculation of children with well-controlled type 1 DM and to compare these results with those obtained from healthy children. DESIGN Cross-sectional prospective study. METHODS This study enrolled 60 patients with DM without clinically detectable diabetic retinopathy (DR) and 57 age-matched control subjects. Optical coherence tomography angiography (OCT-A) was performed using AngioVue (Avanti, Optivue). Foveal avascular zone (FAZ) area, nonflow area, superficial and deep vessel densities, FAZ perimeter, acircularity index of FAZ (AI; the ratio of the perimeter of FAZ and the perimeter of a circle with equal area), and foveal density (FD-300; vessel density in 300 μm around FAZ) were analyzed. Correlations between the investigated OCT-A parameters with DM duration and glycated hemoglobin (HbA1c) levels were evaluated among patients with type 1 DM. RESULTS Differences in the mean values for FAZ perimeter, AI, and FD-300 were statistically significant between DM group and control group (P < .001, P = .001, and P = .009, respectively). There were also statistically significant differences between the groups for vessel densities of deep superior hemi-parafovea, deep temporal parafovea, and deep superior parafoveal zones (P = .008, P = .015, and P = .005, respectively). There were no significant correlations between DM duration and HbA1c levels with the investigated OCT-A parameters. CONCLUSION Diabetic eyes without clinically detectable DR exhibited alterations in FD-300, AI, perimeter, and vessel density of parafoveal capillaries in deep capillary plexus preceding the enlargement of FAZ; therefore, these new parameters might be sensitive imaging biomarkers to define early DR.

Assessment of Serum Concentrations of Adropin, Afamin, and Neudesin in Children with Type 1 Diabetes. BIOMED RESEARCH INTERNATIONAL 2019; 2019:6128410. [PMID: 31781629 PMCID: PMC6855013 DOI: 10.1155/2019/6128410] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/01/2019] [Accepted: 09/10/2019] [Indexed: 02/07/2023]
Abstract
Introduction The increasing knowledge of adropin, afamin, and neudesin and the regulation of glucose metabolism and insulin resistance allows for the assessment of the differences in their concentrations between the groups with varied duration of diabetes mellitus (DM). Aim of the Study Assessment of serum levels of adropin, afamin, and neudesin in children with type 1 diabetes, with respect to the disease duration. Materials and Methods The study consisted of 138 patients aged 5–18 years (M 40.58%). Children with type 1 diabetes (n = 68) were compared to the control group (n = 70). The diabetic group was divided into 4 subgroups: (I) newly diagnosed patients, after an episode of ketoacidosis (n = 14), (II) duration no longer than 5 years (n = 18), (III) 5 to 10 years (n = 27), and (IV) longer than 10 years (n = 9). Serum concentrations of adropin, afamin, and neudesin were assessed and compared between the groups of patients. The criterion for statistical significance was p < 0.05. Results The concentrations of adropin and afamin across all subgroups were lower than that in the control group, while neudesin levels were higher in diabetic patients compared to the control group. The differences were statistically significant. Conclusions Adropin, afamin, and neudesin may play a major role in the regulation of glucose metabolism and have a significant potential as novel biomarkers to predict future metabolic disorders. However, further multicentre studies on a larger cohort of patients are necessary to specify the role of these substances in the course and treatment of type 1 diabetes.
