Abstract
Diabetic kidney disease is distinguished by the presence of albuminuria, hypertension, declining kidney function, and a markedly elevated cardiovascular disease risk. This constellation of clinical features drives the premature mortality associated with type 1 diabetes. The first epidemiological investigations concerning type 1 diabetes-related albuminuria date back to the 1980s. The early studies found that proteinuria - largely equivalent to severe albuminuria - developed in 35 to 45% of individuals with type 1 diabetes, with the diabetes duration-specific incidence rate pattern portraying one or two peaks. Furthermore, moderate albuminuria, the first detectable sign of diabetic kidney disease, was found to nearly inexorably progress to overt kidney disease within a short span of time. Since the early reports, studies presenting more updated incidence rates have appeared, although significant limitations such as study populations that lack broad generalizability, study designs vulnerable to substantive selection bias, and constrained follow-up times have been encountered by many. Nevertheless, the most recent reports estimate that in modern times, moderate - instead of severe - albuminuria develops in one-third of individuals with type 1 diabetes; yet, a considerable part (up to 40% during the first ten years after the initial albuminuria diagnosis) progresses to more advanced stages of the disease over time. An alternative pathway to albuminuria progression is its regression, which affects up to 60% of the individuals, but notably, the relapse rate to a more advanced disease stage is high. Whether albuminuria regression translates into a decline in cardiovascular disease and premature mortality risk is an area of debate, warranting more detailed research in the future. Another unclear but alarming feature is that although the incidence of severe albuminuria has fallen since the 1930s, the decline seems to have reached a plateau after the 1980s. This stagnation may be due to the lack of kidney-protective medicines since the early 1980s, as the recent breakthroughs in type 2 diabetes have not been applicable to type 1 diabetes. Therefore, novel treatment strategies are at high priority within this patient population.

Acta Diabetol 2021; 58:145-152. [PMID: 32915299 DOI: 10.1007/s00592-020-01597-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Accepted: 08/12/2020] [Indexed: 02/03/2023]
Abstract
AIMS Disparities in health outcomes in pediatric type 1 diabetes (T1D) based on race/ethnicity and socioeconomic position (SEP) have been reported. We compared T1D characteristics between Eritrean status-less children living in Israel and native-born Israeli children. METHODS This observational study compared 7 Eritrean and 28 Israeli children (< 8 years old at T1D diagnosis) who were diagnosed in a single diabetes center during 2015-2019. Sociodemographic and diabetes-related data from diagnosis until the last clinic visit were retrieved from their medical files. RESULTS At diagnosis, the mean age was 4.8 ± 2.2 years, 17 (48.6%) had diabetic ketoacidosis with a mean HbA1c level of 10.5 ± 2.1% (91.3 mmol/mol) and 29 (82.9%) had ≥ 2 pancreatic autoantibodies. The mean T1D duration of follow-up was 2.7 ± 1.4 years. Overall glycemic control during follow-up (> 6 months from diagnosis, mean number of samples 10.6 ± 5.2) was good, with mean, best, and peak HbA1c levels of 7.4 ± 0.8% (57.4 mmol/mol), 6.7 ± 0.7% (49.7 mmol/mol), and 8.1 ± 1.1% (65 mmol/mol), respectively. Thirty-two children (91.4%) used continuous glucose monitoring devices (CGMs), and the mean time from diagnosis to CGM initiation was 10.8 ± 14.1 months. CGM metrics: time CGM active: 95.4 ± 3.8%, mean glucose level: 170.0 ± 27.0 mg/dl (9.4 mmol/L), time-in-range: 56.4 ± 14.7%, time-below-range: 5.5 ± 5.7%, and time-above-range: 38.6 ± 16.1%. Diabetes-related parameters at diagnosis and during follow-up were similar between groups. Eritrean children had significantly lower SEPs (P < 0.001) and parental education levels (P < 0.001). Correlations between SEP and diabetes parameters and SEP and growth parameters were not significant. CONCLUSIONS Eritrean status-less children in Israel achieved glycemic targets similar to those of Israeli children, perhaps reflecting uniformity in the standard of care and CGM usage.

Health-related quality of life and metabolic control in immigrant and Italian children and adolescents with type 1 diabetes and in their parents. Pediatr Diabetes 2020; 21:1031-1042. [PMID: 32418308 DOI: 10.1111/pedi.13042] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2020] [Revised: 04/23/2020] [Accepted: 05/08/2020] [Indexed: 02/01/2023] Open
Abstract
OBJECTIVE To determine if the diabetes-specific health-related quality of life (D-HRQOL) of young people with type 1 diabetes (T1D) and their parents is influenced by migrant status. SUBJECTS AND METHODS One hundred and twenty-five patients (12.4 ± 3.55 years, males 53.6%) with T1D and their parents (102 mothers, 37 fathers) were enrolled and categorized into: group A (both foreign parents) and group B (both native Italian parents). The Pediatric Quality of Life Inventory™ 3.0 Diabetes Module (PedsQL™ 3.0 DM) was used to evaluate the D-HRQOL. Data on diabetic ketoacidosis (DKA) at T1D onset, insulin therapy, and glycosylate hemoglobin (HbA1c) were also collected. RESULTS Group A (n = 40), compared to group B (n = 85), had higher frequency of DKA at T1D onset (P < .001) and a lower use of sensor augmented insulin pump (P = .015). HbA1c values were higher in group A than in group B (P < .001). Patients' "Diabetes symptoms" (P = .004), "Treatment barriers" (P = .001), and "Worry" (P = .009) scales scores were lower in group A than in group B. Mothers of group A had lower scores in "Diabetes symptoms" (P = .030), "Treatment barriers" (P < .001), "Treatment adherence" (P = .018), "Communication" (P = .009) scales, and total score (P = .011) compared to the group B ones. High PedsQL™ 3.0 DM was significantly associated with being Italian, being prepubertal, and having lower HbA1c mean levels. CONCLUSIONS Being a migrant confers disadvantages in terms of D-HRQOL and metabolic control in children and adolescents with T1D. Specific educational interventions should be considered in the clinical care of patients with migration background, to improve D-HRQOL and health status.

Abstract
PURPOSE OF REVIEW Patients with type 1 diabetes have increased risk for cardiovascular disease. The purpose of this review is to examine the following: i) current evidence for subclinical cardiovascular disease (CVD) in children with type 1 diabetes (T1DM) ii) known modifiable risk factors for CVD and their relationship to subclinical CVD in this population iii) studies that have addressed these risk factors in order to improve CVD outcomes in children with T1DM RECENT FINDINGS: Subclinical CVD presents in children as increased carotid intima-media thickness, increased arterial stiffness, and endothelial and myocardial dysfunction. Modifiable risk factors for CVD include hyperglycemia, hyperlipidemia, obesity, hypertension, depression, and autonomic dysfunction. Very few randomized controlled studies have been done in children with T1DM to examine how modification of these risk factors can affect their CVD. Children with T1DM have subclinical CVD and multiple modifiable risk factors for CVD. More research is needed to define how modification of these factors affects the progression of CVD.

Abstract
PURPOSE To evaluate the relationship between retinal vascular caliber and kidney function in a cohort of Australian children and adolescents with type 1 diabetes. METHODS This was a cross-sectional study of 483 children and adolescents with type 1 diabetes, aged 7-18 years. An audit of medical files of participants who attended the Royal Children's Hospital, Melbourne, between January 2009 and March 2014 was performed. Albumin to creatinine ratio (ACR) was acquired through spot urine samples and microalbuminuria was classified as ACR >3.5 mg/mmol in females and >2.5 mg/mmol in males. Retinal vascular caliber was measured using a standardized protocol and later summarized as central retinal arteriolar equivalent (CRAE) and central retinal venular equivalent (CRVE). RESULTS CRAE was significantly narrower in participants with microalbuminuria compared to those with normo-albuminuria in crude analysis (mean ± standard deviation 159.07 ± 9.90µm vs 164.49 ± 12.45 µm; p = 0.006). After adjustment for key confounders and known or potential mediators of microalbuminuria (age, sex, ethnicity, hemoglobin A1c, systolic blood pressure, total cholesterol, body mass index, duration of diabetes and CRVE) the association between narrower CRAE and microalbuminuria was attenuated and was no longer significant (95% confidence interval 0.94-1.02, p = 0.222). No significant associations between CRVE or arteriole-to-venule ratio and microalbuminuria were observed in univariate or multivariate models. CONCLUSIONS After adjustment for potential confounding variables, retinal vascular caliber was not significantly associated with microalbuminuria in this sample of children and adolescents with type 1 diabetes. Future prospective longitudinal research is warranted to further evaluate these findings.

Abstract
OBJECTIVE To explore the relationship between certain clinical variables and metabolic HbA1c at diagnosis correlated to HbA1c at follow-up (p < 0.001). There was a clear gender difference regarding HbA1c. Girls had higher values both at diagnosis and at follow-up (p < 0.001). Girls also had lower BMI and pH at diagnosis than boys (p < 0.001). In contrast, girls with the highest body mass index (BMI) at follow-up had higher mean HbA1c at follow-up in 2010 (p < 0.001). Having a mother and/or a father with high BMI implied higher HbA1c at diagnosis (p < 0.003). CONCLUSIONS HbA1c at diagnosis seems to predict metabolic control years later. There is a gender difference at diagnosis as female patients have higher HbA1c than males at diagnosis as well as at follow up. As metabolic control is very much correlated to complications there is a need to early identify patients at risk of poor metabolic control. Even though we do not know whether a high HbA1c level is mainly due to severity of the disease or to behavioral patterns, new ways to treat and support these children, especially girls, are needed.

Abstract
Objective To study the impact of maternal country of birth on type-1-diabetes (T1D) therapy and outcome. Study Design and Methods 27,643 T1D patients aged ≤20 years with documented maternal country of birth from the multicenter German/Austrian diabetes patient registry (DPV) were analyzed. Patients were categorized based on their mother’s origin: Germany/Austria (reference), Turkey, Southern Europe, and Eastern Europe. To compare BMI standard deviation score (BMI-SDS), diabetes therapy and outcome between groups, multivariable regression was applied with adjustments for age, sex and duration of diabetes. Based on observed marginal frequencies, adjusted estimates were calculated. Linear regression was used for continuous data, logistic regression for binary data and Poisson regression for count data. All statistical analyses were performed using SAS 9.4. Significance was set at a two-tailed p<0.05. Results 83.3% of patients were offspring of native mothers. A Turkish, Southern or Eastern European background was documented in 2.4%, 1.7% and 4.3% of individuals. After demographic adjustment, patients with migration background had a higher mean BMI-SDS (Turkey, Southern Europe or Eastern Europe vs. Germany/Austria: 0.58±0.03, 0.40±0.04, or 0.37±0.02 vs. 0.31±0.01; ±SE) and a lower use of insulin pumps (26.8%, 27.9%, or 32.6% vs. 37.9%) compared to offspring of native mothers. Mean HbA1c was worst in individuals of Turkish mothers (Turkey vs. Germany/Austria: 69.7±0.7 vs. 66.6±0.1 mmol/mol; ±SE). Patients of Eastern European descent had an increased rate of severe hypoglycemia (22.09±0.13 vs. 16.13±0.02 events per 100 patient-years) and ketoacidosis was more prevalent in offspring of Turkish or Southern European mothers (7.50±0.10, or 7.13±0.11 vs. 6.54±0.02 events per 100 patient-years). Patients of Turkish descent were more often hospitalized (57.2±2.7 vs. 48.5±0.4 per 100 patient-years). All differences were significant. Conclusion The differences in diabetes therapy and outcome among patients with distinct migration background suggest that specific challenges have to be considered in clinical care.

Urinary MicroRNA Profiling Predicts the Development of Microalbuminuria in Patients with Type 1 Diabetes. J Clin Med 2015; 4:1498-517. [PMID: 26239688 PMCID: PMC4519802 DOI: 10.3390/jcm4071498] [Citation(s) in RCA: 67] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2015] [Revised: 07/06/2015] [Accepted: 07/14/2015] [Indexed: 12/27/2022] Open
Abstract
Microalbuminuria provides the earliest clinical marker of diabetic nephropathy among patients with Type 1 diabetes, yet it lacks sensitivity and specificity for early histological manifestations of disease. In recent years microRNAs have emerged as potential mediators in the pathogenesis of diabetes complications, suggesting a possible role in the diagnosis of early stage disease. We used quantiative polymerase chain reaction (qPCR) to evaluate the expression profile of 723 unique microRNAs in the normoalbuminuric urine of patients who did not develop nephropathy (n = 10) relative to patients who subsequently developed microalbuminuria (n = 17). Eighteen microRNAs were strongly associated with the subsequent development of microalbuminuria, while 15 microRNAs exhibited gender-related differences in expression. The predicted targets of these microRNAs map to biological pathways known to be involved in the pathogenesis and progression of diabetic renal disease. A microRNA signature (miR-105-3p, miR-1972, miR-28-3p, miR-30b-3p, miR-363-3p, miR-424-5p, miR-486-5p, miR-495, miR-548o-3p and for women miR-192-5p, miR-720) achieved high internal validity (cross-validated misclassification rate of 11.1%) for the future development of microalbuminuria in this dataset. Weighting microRNA measurements by their number of kidney-relevant targets improved the prognostic performance of the miRNA signature (cross-validated misclassification rate of 7.4%). Future studies are needed to corroborate these early observations in larger cohorts.

Abstract
OBJECTIVE To investigate whether celiac disease (CD) associated with type 1 diabetes increases the risk of microvascular complications. RESEARCH DESIGN AND METHODS Patients (n = 56,514) aged >10 years with diabetes duration <20 years from 392 centers in Germany and Austria were assigned to one of three categories (n): no CD (50,933), biopsy-confirmed CD (812), or suspected CD (4,769; clinical diagnosis or positive antibodies). The confirmed and suspected groups were combined and analyzed for retinopathy or nephropathy. Cox proportional hazards regression was used to adjust for potential confounders (glycated hemoglobin [HbA1c], age at diabetes onset, sex, smoking, dyslipidemia, and hypertension). RESULTS Kaplan-Meier analysis revealed that retinopathy and nephropathy occurred earlier in the presence versus absence of CD: retinopathy at age 26.7 years (95% CI 23.7-30.2) in 25% of patients with CD vs. age 33.7 years (33.2-34.4) in 25% without CD and microalbuminuria at age 32.8 years (29.7-42.5) vs. 42.4 years (41.4-43.3). The adjusted risk for both retinopathy (hazard ratio 1.263 [95% CI 1.078-1.481]) and nephropathy (1.359 [1.228-1.504]) was higher in patients with diabetes and CD versus those without CD. Cox regression revealed CD as an independent risk factor for microvascular complications after adjustment for confounders. CONCLUSIONS CD is an independent risk factor for retinopathy and nephropathy in patients with type 1 diabetes. Our study therefore supports the recommendation for regular serologic testing for CD, even in the absence of clinical CD. Further prospective studies are required to investigate whether a gluten-free diet might reduce the risk of microvascular disorders in patients with diabetes and CD.
