High diabetes distress level was found in 22.8% of participants. Lack of confidence in self-care (6.0 vs 3.0, p=0.002), negative emotional consequences (10.0 vs 6.0, p=0.004), and overall score (18.75 vs 11.25, p=0.002) were higher in adult than in adolescent males, when adjusted for age at T1D onset. Negative emotional consequences (13.0 vs 10.0, p=0.005) and overall score (25.0 vs 20.0, p=0.016) were higher in adult compared to adolescent females, when adjusted for age at T1D onset. Lack of confidence in self-care (6.0 vs 3.0, p=0.002), negative emotional consequences (10.0 vs 6.0, p=0.015), and overall score (20.0 vs 11.2, p=0.005) were higher in adolescent females compared to males, when adjusted for age at T1D onset. Negative emotional consequences score was higher in adult females compared to males (13.0 vs 10.0, p=0.029), when adjusted for age at T1D onset. In conclusion, our findings show that patients with T1D have greater burden of diabetes distress in emerging adulthood than in adolescence and add to evidence suggesting the importance of addressing diabetes distress in clinical care and the necessity of wider picture beyond the physical manifestation of diabetes to be taken into consideration.
Identifying gene variants causing monogenic diabetes increases understanding of disease etiology and allows for implementation of precision therapy to improve metabolic control and quality of life. Here, we aimed to assess the prevalence of monogenic diabetes in diabetic youth in Lithuania, uncover potential diabetes-related gene variants, and prospectively introduce precision treatment. First, we assessed all pediatric and most young adult diabetic patients in Lithuania (n = 1209) for diabetesrelated autoimmune antibodies. We then screened all antibody-negative patients using targeted high-throughput sequencing of more than 300 potential candidate genes. In this group, 40.7% had monogenic diabetes, with the highest percentage (100%) in infants (diagnosis at ages 0-12 months), followed by those diagnosed at ages >1-18 years (40.3%) and at >18-25 years (22.2%). The overall prevalence of monogenic diabetes in diabetic youth in Lithuania was 3.5% (1.9% for GCK diabetes, 0.7% for HNF1A, 0.2% for HNF4A and ABCC8, 0.3% for KCNJ11, and 0.1% for INS). Furthermore, we identified likely pathogenic variants in 11 additional genes. Microvascular complications were present in 26% of those with monogenic diabetes. Prospective treatment change was successful in over 50% of eligible candidates, with C-peptide over 252 pmol/L emerging as the best prognostic factor.
BackgroundCardiovascular autonomic neuropathy (CAN) increases morbidity and mortality in diabetes through association with a high risk of cardiac arrhythmias and sudden death, possibly related to silent myocardial ischemia. During the sub-clinical stage, CAN can be detected through reduction in heart rate variability (HRV). The aim of our study was to estimate if the time and frequency-domain analysis can be valuable for detecting CAN in young patients with type 1 diabetes mellitus (T1DM).MethodsFor this case control study of evaluation of cardiovascular autonomic function the 15–25 years age group of patients with duration of T1DM more than 9 years (n = 208, 89 males and 119 females) were selected. 67 patients with confirmed CAN were assigned to the “case group” and 141 patients without CAN served as a control group, the duration of T1DM was similar (15.07 ± 4.89 years vs.13.66 ± 4.02 years; p = 0.06) in both groups. Cardiovascular autonomic reflex tests and time and frequency domains analysis of HRV were performed for all subjects.ResultsTime domain measures were significantly lower in CAN group compared with control (p < 0.05). R-R max / R-R min ratio and coefficient of variation (CV) were the lowest during deep breathing among T1DM patients with CAN. Receivers operating characteristic (ROC) curves were constructed to compare the accuracies of the parameters of time-domain analysis for diagnosing CAN. We estimated a more reliable cut-off value of parameters of time-domain. The CV values in supine position <1.65, reflected sensitivity 94.3%, specificity 91.5%. The CV values during deep breathing <1.45 reflected sensitivity 97.3%, specificity 96.2%. The CV values in standing position <1.50 reflected sensitivity 96.2%, specificity 93.0%. The most valuable CV was during deep breathing (AUC 0.899). The results of frequency-domain (spectral analysis) analysis showed significant decrease in LF power and LFPA, HF Power and HFPA, total power among subjects with CAN than compared with subjects without CAN (p < 0.05).ConclusionsTime and frequency domain analysis of HRV permits a more accurate evaluation of cardiovascular autonomic function, providing more information about sympathetic and parasympathetic activity. The coefficient of variation (time-domain analysis) especially during deep breathing could be valuable for detecting CAN.
The presence of obesity and GDM has a significant impact on both maternal and fetal complications. The metabolic syndrome can be diagnosed not only after pregnancy but also during pregnancy.
Cardiovascular risk and obesity are becoming major health issues among individuals with type 1 diabetes (T1D). The aim of this study was to evaluate cardiovascular risk factors and obesity in youth with T1D in Lithuania. Methods. 883 patients under 25 years of age with T1D for at least 6 months were investigated. Anthropometric parameters, blood pressure, and microvascular complications were evaluated, and the lipid profile and HbA1c were determined for all patients. Results. Study subjects’ mean HbA1c was 8.5±2%; 19.5% were overweight and 3.6% obese. Hypertension and dyslipidemia were diagnosed in 29.8% and 62.6% of participants, respectively. HbA1c concentration was directly related to levels of total cholesterol (r=0.274, p<0.001), LDL (r=0.271, p<0.001), and triglycerides (r=0.407, p<0.001) and inversely associated with levels of HDL (r=0.117, p=0.001). Prevalence of dyslipidemia increased with duration of diabetes (p<0.05). Hypertension was more prevalent in overweight and obese compared to normal-weight patients (40.6 and 65.6 vs. 25.6%, respectively, p<0.001). Frequency of microvascular complications was higher among patients with dyslipidemia (27.2 vs. 18.8%, p=0.005) and among those with hypertension (25.9 vs. 23.2%, p<0.001). Conclusion. The frequency of cardiovascular risk factors is high in youth with T1D and associated with diabetes duration, obesity, and metabolic control.
Background and objectives: This study aimed to assess the clinical significance of serum cystatin C in the early diagnosis of renal injury and its association with dyslipidemia in young T1D patients. Materials and Methods: A total of 779 subjects were evaluated for kidney function by estimating glomerular filtration rate (eGFR) based on serum creatinine (eGFRcreat) and cystatin C (eGFRcys). Results:The median age of study subjects was 16.2 years (2.1;26.4), diabetes duration—5.3 years (0.51;24.0). The median of HbA1c was 8% (5.2;19.9) (64 mmol/mol (33.3;194)); 24.2% of participants had HbA1c < 7% (53 mmol/mol). Elevated albumin excretion rate was found in 13.5% of subjects. The median of cystatin C was 0.8 mg/L (0.33;1.71), the median of creatinine—63 µmol/L (6;126). The median of eGFRcys was lower than eGFRcreat (92 mL/min/1.73 m2 vs. 101 mL/min/1.73 m2, p < 0.001). A total of 30.2% of all patients were classified as having worse kidney function when using cystatin C vs. creatinine for eGFR calculation. Linear correlations were found between cystatin C and HbA1c, r = −0.088, p < 0.05, as well as cystatin C and HDL, r = −0.097, p < 0.01. Conclusions: This study showed that cystatin C might be used as an additional biomarker of early kidney injury in young patients with T1D.
BackgroundInitial classification of diabetes of young may require revision to improve diagnostic accuracy of different forms of diabetes.The aim of our study was to examine markers of beta-cell autoimmunity in a cohort of young (0–25 years) patients with type 1 diabetes and compare the presentation and course of the disease according to the presence of pancreatic antibodies.MethodsCross-sectional population-based study was performed covering 100% of pediatric (n = 860) and 70% of 18–25 years old adult patients (n = 349) with type 1 diabetes in Lithuania.ResultsNo antibodies (GAD65, IA-2, IAA and ICA) were found in 87 (7.5%) cases. Familial history of diabetes was more frequent in those with antibodies-negative diabetes (24.1 vs. 9.4%, p < 0.001). Gestational age, birth weight and age at diagnosis was similar in both groups. Ketosis at presentation was more frequent in patients with autoimmune diabetes (88.1 vs. 73.5%, p < 0.05). HbA1c at the moment of investigation was 8.6 (3) vs. 8.7 (2.2)% in antibodies-negative and antibodies-positive diabetes groups, respectively, p > 0.05. In the whole cohort, neuropathy was found in 8.8% and nephropathy - in 8.1% of cases, not depending on autoimmunity status. Adjusted for age at onset, disease duration and HbA1c, retinopathy was more frequent in antibodies-negative subjects (13.8 vs. 7.8%, p < 0.05).ConclusionAntibodies-negative pediatric and young adult patients with type 1 diabetes in this study had higher incidence of family history of diabetes, higher frequency of retinopathy, less frequent ketosis at presentation, but similar age at onset, HbA1c, incidence of nephropathy and neuropathy compared to antibodies-positive patients.
