Correlation of HbA1c Level with Lipid Profile in Type 2 Diabetes Mellitus Patients Visiting a Primary Healthcare Center in Jeddah City, Saudi Arabia: A Retrospective Cross-Sectional Study. Diseases 2023; 11:154. [PMID: 37987265 PMCID: PMC10660465 DOI: 10.3390/diseases11040154] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 10/23/2023] [Accepted: 10/27/2023] [Indexed: 11/22/2023] Open
Abstract
INTRODUCTION Type 2 diabetes mellitus (T2DM) patients are at high risk of dyslipidemia, which in turn is associated with macrovascular diseases, such as heart diseases and stroke, and microvascular diseases, such as neuropathy and nephropathy. There are contradictory findings in the literature regarding the relationship between glycated hemoglobin (HbA1c) and the lipid profile among T2DM patients. This study was performed to investigate the association between HbA1c level and the lipid profile in elderly T2DM patients at a primary care hospital in Jeddah City, Saudi Arabia. METHODS This study is a retrospective cross-sectional study conducted at the Prince Abdul Majeed Healthcare Center (PAMHC) in Jeddah, Saudi Arabia. The sociodemographic and clinical data of the T2DM patients who had visited the PAMHC from 1 January 2020 to 31 December 2021, were collected from the data registry of the PAMHC and analyzed for publication. RESULTS The study included a total of 988 T2DM patients (53.3% male). Of the participants, 42.9% were aged between 55 and 64 years. Dyslipidemia parameters were presented as high LDL-c (in 60.3% cases), low HDL-c (in 39.8% cases), high triglycerides (in 34.9% cases), and high total cholesterol (in 34.8% cases). The correlation of HbA1c with total cholesterol (TC) and triglycerides (TGs) was positively significant, thereby highlighting the important link between glycemic control and dyslipidemia. A mean increase of 4.88 mg/dL and 3.33 mmHg in TG level and diastolic blood pressure, respectively, was associated with the male gender, in comparison to the female gender. However, the male gender was significantly associated with the reduction in the mean cholesterol level, BMI, HbA1c, HDL-c, and LDL-c by 11.49 mg/dL, 1.39 kg/m2, 0.31%, 7.47 mg/dL, and 5.6 mg/dL, respectively, in comparison to the female gender. CONCLUSIONS The results of this study show that HbA1c was significantly associated with cholesterol and triglyceride levels in the T2DM patients included in the study. Our findings highlight the important relationship between glycemic control and dyslipidemia.

Prevalence of LDL-hypercholesterolemia and other cardiovascular risk factors in young people with type 1 diabetes. J Clin Lipidol 2023; 17:483-490. [PMID: 37258406 DOI: 10.1016/j.jacl.2023.05.097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 05/10/2023] [Accepted: 05/16/2023] [Indexed: 06/02/2023]
Abstract
BACKGROUND Mortality and morbidity in people with Type 1 diabetes (T1D) is mainly caused by cardiovascular disease (CVD). Early treatment of cardiovascular risk factors (CVRFs) is of great importance. OBJECTIVE To analyze the prevalence of LDL-hypercholesterolemia and other CVRFs in youth with T1D. METHODS Clinical and laboratory parameters, and vascular thickness measurement were obtained in youth with T1D (age 6-18 years, T1D duration >1 year) attending a diabetes clinic. LDL-hypercholesterolemia, microalbuminuria and arterial hypertension were defined as CVRFs. RESULTS A total of 333 youth (48% girls; age: 13.3 years [10.3-15.5], median [interquartile range]) participated in the study. The T1D duration was 5.9 years [3.5-9.4] with HbA1c of 7.4% [6.8-8.0]. Intima media thickness (N=223) was 538.0 µm [470.0-618.0]). LDL-hypercholesterolemia was present in 30 participants (9%; 18 girls; age: 14.3 years [11.2-15.7]). None of the participants had persistent microalbuminuria, although 59 (18.3%) had elevated albumin excretion in a random urine specimen. LDL-hypercholesterolemia was associated with increased blood pressure (p<0.05), insulin requirement (p<0.05), HbA1c (p<0.05), triglyceride (p<0.001) and total cholesterol (p<0.001), and a family history of premature CVD (p<0.001), but negatively correlated with HDL cholesterol levels (p<0.05). Sex, pubertal status, duration of diabetes, type of therapy, and physical activity did not differ between participants with and without LDL- hypercholesterolemia. Arterial hypertension was present in 11 participants (3.3%; 4 girls; age: 14.1 years [11.1-16.1]). CONCLUSION LDL-hypercholesterolemia affected 9% of youth with T1D in this cohort and was associated with other CVRFs. A holistic therapeutic concept for these young people is essential.

Abstract
Objective: Dyslipidemia is prevalent in adults living with type 1 diabetes, and it can worsen the presentation of microvascular complications such as retinopathy. This study aims to identify the pattern coupled with the frequency of dyslipidemia in diabetic adults who followed up at different clinics in King Abdulaziz Medical City, Riyadh, and evaluate the associations with demographic and clinical characteristics. Methods: A cross-sectional, retrospective chart review study of 514 adults with type 1 diabetes was conducted in a tertiary health care facility in the central region of Saudi Arabia. Demographics were retrieved by using the implemented electronic medical records. Fasting lipid profile, glycated hemoglobin (HbA1c), and thyroid-stimulating hormone (TSH) levels were checked for all subjects. Results: Five hundred and fourteen (514) subjects aged 18-65 years were studied (mean age: 26.1 ± 7.1 years). There were 318 (62%) females in the sample, and their mean age was significantly different from the mean age of males (p = 0.01). The mean duration of having diabetes was 12.8 ± 6.9 years. The prevalence of lipid abnormalities included abnormal low-density lipoprotein (LDL) (70%), hypercholesterolemia (23%), abnormal high-density lipoprotein (HDL) (8%), and hypertriglyceridemia (5%). Abnormal HDL was significantly higher in males than in females (p=<0.001). There were no statistically significant differences in the prevalence of other lipid abnormalities between the two genders and the age group < or ≥ 25 years. There was no statistically significant difference in the mean of the tested lipids levels between the two genders. One hundred and forty-three (143) (27.8%) patients had more than one abnormal lipid condition. A statistically significant difference was observed in the mean HbA1c between males and females (p=0.001). Otherwise, there was no significant association of lipid abnormalities with gender, age, diabetes duration, and weight. Conclusion: The most prevalent lipid abnormality was high LDL cholesterol. Nearly a third of the tested individuals had more than one lipid abnormality. Furthermore, poor glycemic control was linked to abnormal lipid profiles. Consequently, local programs must aim to screen and intervene early to delay and prevent future severe vascular complications related to non-treated dyslipidemia.

Abstract
A literature search was conducted to identify publications addressing the early phases of lipid phenotypes in children and adults with either type 1 diabetes or type 2 diabetes. Medline, EMBASE, and Ovid were searched using the following search terms: clinical remission, partial remission, partial clinical remission, honeymoon phase, C-peptide, type 1 or 2 diabetes, children, pediatric type 1 or 2 diabetes, and paediatrics type 1 or 2 diabetes, adults, adult type 1 or type 2 diabetes. Partial clinical remission (PR) of type 1 diabetes (T1D) is characterized by continued endogenous production of insulin and C-peptide following the diagnosis and the introduction of exogenous insulin therapy. PR is associated with improved glycemic control and reduced prevalence of diabetes complications. The theory of hyperglycemic memory was proposed to explain this concept of improved glycemic outcomes in remitters (those who experienced PR) versus non-remitters (those who did not experience PR). However, this theory is incomplete as it does not explain the dichotomy in early lipid phenotypes in T1D based on PR status, which is an understudied area in diabetology and lipidology. To fill this knowledge gap, we propose the Theory of Hyperlipidemic Memory of T1D. This theory is premised on our 5-year research on early post-diagnostic dichotomy in lipid phenotypes between remitters and non-remitters across the lifespan. It provides a more rigorous explanation for the differences in lifelong atherosclerotic cardiovascular disease (ASCVD) risk between remitters and non-remitters. We conducted 4 clinical studies in pediatric and adult subjects with diabetes mellitus to characterize the particulars of the hyperlipidemic memory. In the first investigation, we explored the impact of the presence or absence of PR on lipid parameters in children and adolescents with T1D. In the second, we investigated whether pubertal maturation influenced our findings in T1D; and whether these findings could be replicated in healthy, non-diabetic children and adolescents. In the third, we leveraged our findings from T1D and controls to investigate the mechanisms of early lipid changes in T2D by comparing the earliest lipid phenotype of subjects with type 2 diabetes (T2D) to those of remitters, non-remitters, and controls. In the fourth, we investigated the impact of PR on the earliest lipid phenotypes in adults with T1D and compared these early lipid data to those of T2D subjects and controls. This body of work across the lifespan in children, adolescents, and adults supports the Theory of Hyperlipidemic Memory. This new theory clarifies why PR largely determines the risks for early-phase dyslipidemia, mid-term microvascular disease risk, and long-term ASCVD risk in subjects with T1D.

Abstract
Abstract
Background
Hyperglycemia and dyslipidemia are commonly found metabolic abnormalities in diabetic children and adolescents and both increase the risk of cardiovascular disease. This study aimed to assess the prevalence and the pattern of dyslipidemia in Egyptian children and adolescents with type 1 diabetes (T1DM) and determine its relation with the glycemic control.
Results
This retrospective study included 806 children and adolescents with T1DM; 358 (44.42%) males and 448 (55.58%) females. Their mean age was 11.71 ± 3.6 years. Clinical and laboratory data were recruited from patients’ files. Laboratory data include the most recent fasting lipid profile (triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL) and low-density lipoprotein (LDL)), and the mean glycosylated hemoglobin (HbA1c) levels over the preceding year presented in percentage were calculated. Dyslipidemia in children and adolescents with T1DM represented 70.47% (568 patients). No statistically significant differences were detected between patients with and without dyslipidemia. As regards the pattern of dyslipidemia, high LDL and low HDL were the most frequent abnormalities in the study group; 62.16%, 60.21%, respectively. Patients with poor glycemic control (HbA1c > 7.5%) represent 73.45% and they were significantly older, with longer diabetes duration and higher TC, TG, and LDL compared to patients with good glycemic control. Significant positive correlations were found between HbA1c, TG, TC, and LDL with the age and diabetes duration.
Conclusion
We detected high prevalence of dyslipidemia in children and adolescents with T1DM. Therefore, dyslipidemia should be screened for in earlier ages in Egyptian children and adolescents suffering from T1DM. Programs directed to the prevention of dyslipidemia should be conducted, particularly for this group, in order to prevent/delay cardiovascular complications related to dyslipidemia. Also, parents should receive proper education targeting the prevention, control, and care of their diabetic children with dyslipidemia.

Advanced lipoprotein profile disturbances in type 1 diabetes mellitus: a focus on LDL particles. Cardiovasc Diabetol 2020; 19:126.

Abstract
Background Lipoprotein disturbances have been associated with increased cardiovascular disease (CVD) risk in type 1 diabetes mellitus (T1DM). We assessed the advanced lipoprotein profile in T1DM individuals, and analysed differences with non-diabetic counterparts. Methods This cross-sectional study involved 508 adults with T1DM and 347 controls, recruited from institutions in a Mediterranean region of Spain. Conventional and advanced (assessed by nuclear magnetic resonance [NMR] spectroscopy) lipoprotein profiles were analysed. Crude and adjusted (by age, sex, statin use, body mass index and leukocyte count) comparisons were performed. Results The median (interquartile range) age of the study participants was 45 (38–53) years, 48.2% were men. In the T1DM group, the median diabetes duration was 23 (16–31) years, and 8.1% and 40.2% of individuals had nephropathy and retinopathy, respectively. The proportion of participants with hypertension (29.5 vs. 9.2%), and statin use (45.7% vs. 8.1%) was higher in the T1DM vs. controls (p < 0.001). The T1DM group had a better conventional (all parameters, p < 0.001) and NMR-lipid profile than the control group. Thus, T1DM individuals showed lower concentrations of atherogenic lipoproteins (VLDL-particles and LDL-particles) and higher concentrations of anti-atherogenic lipoproteins (HDL-particles) vs. controls, even after adjusting for several confounders (p < 0.001 for all). While non-diabetic women had a more favourable lipid profile than non-diabetic men, women with T1DM had a similar concentration of LDL-particles compared to men with T1DM (1231 [1125–1383] vs. 1257 [1128–1383] nmol/L, p = 0.849), and a similar concentration of small-LDL-particles to non-diabetic women (672.8 [614.2–733.9] vs. 671.2 [593.5–761.4] nmol/L, respectively; p = 0.790). Finally, T1DM individuals showed higher discrepancies between NMR-LDL-particles and conventional LDL-cholesterol than non-diabetic subjects (prevalence of LDL-cholesterol < 100 mg/dL & LDL-particles > 1000 nmol/L: 38 vs. 21.2%; p < 0.001). All these differences were largely unchanged in participants without lipid-lowering drugs (T1DM, n = 275; controls, n = 317). Conclusions Overall, T1DM participants showed a more favourable conventional and NMR-lipid profile than controls. However, the NMR-assessment identified several lipoprotein derangements in LDL-particles among the T1DM population (higher discrepancies in NMR-LDL-particles vs. conventional LDL-cholesterol; a worse profile in T1DM women) that were overlooked in the conventional analysis. Further studies are needed to elucidate their role in the development of CVD in this population.

Abstract
Background There is limited information about cardiovascular complications among young adults (YA) with type 1 diabetes mellitus (T1DM) who are transitioning from pediatric to adult care. We aimed to study the prevalence and associated factors of dyslipidemia (DLD) and statin treatment in these patients. Methods We recruited 129 YA with T1DM aged 15-25 years. In a cross-sectional analysis, the prevalence of DLD (low-density lipoprotein cholesterol [LDL-C] ≥ 100 mg/dL, high-density lipoprotein cholesterol [HDL-C] <40 mg/dL [males] or <50 mg/dL [females], total cholesterol [TC] ≥200 mg/dL or triglycerides [TG] ≥150 mg/dL) was reported. Socioeconomic and clinical characteristics were compared between YA with and without DLD. We also assessed statin use among YA with DLD. Results DLD was found in 64% of YA, predominantly increased LDL-C (34.9%). Higher mean glycated hemoglobin (HbA1c) was associated with DLD (p < 0.043). Of all YA who met the criteria for statin therapy, only 42% had one prescribed. Conclusions The prevalence of DLD is high in YA with T1DM and is associated with poor glycemic control, and use of statin therapy in this high-risk population is low.

Abstract
The honeymoon phase, or partial clinical remission (PCR) phase, of Type 1 diabetes mellitus (T1DM) is a transitory period that is marked by endogenous insulin production by surviving β cells following a diabetes diagnosis and the introduction of insulin therapy. It is a critical window in the course of the disease that has short and long-term implications for the patient, such as a significant reduction in the risk of long-term complications of T1DM. To promote long-term cardiovascular health in children with newly diagnosed T1DM, three key steps are necessary: the generation of a predictive model for non-remission, the adoption of a user-friendly monitoring tool for remission and non-remission, and the establishment of the magnitude of the early-phase cardiovascular disease risk in these children in objective terms through changes in lipid profile. However, only about 50% of children diagnosed with T1DM experience the honeymoon phase. Accurate and prompt detection of the honeymoon phase has been hampered by the lack of an objective and easily applicable predictive model for its detection at the time of T1DM diagnosis, the complex formulas needed to confirm and monitor PCR, and the absence of a straightforward, user-friendly tool for monitoring PCR. This literature review discusses the most up-to-date information in this field by describing an objective predictive model for non-remission, an easy tool for monitoring remission or non-remission, and objective evidence for the cardiovascular protective effect of PCR in the early phase of the disease. The goal is to present non-remission as an independent clinical entity with significantly poorer long-term prognosis than partial remission.

Abstract
The honeymoon phase, or partial clinical remission (PCR) phase, of Type 1 diabetes mellitus (T1DM) is a transitory period that is marked by endogenous insulin production by surviving 3 cells following a diabetes diagnosis and the introduction of insulin therapy.

Abstract
<b><i>Background:</i></b> Dyslipidaemia is prevalent in children and adolescents with type 1 diabetes and can worsen the presentation of chronic complications such as nephropathy, retinopathy, and neuropathy. The aim of this study is to determine the frequency of dyslipidaemia in children living with diabetes followed up at a paediatric endocrine clinic in southern Nigeria and to identify associations with demographic and clinical characteristics. <b><i>Methods:</i></b> The study is a cross-sectional, descriptive study of 22 children with diabetes followed up in a tertiary health care facility in southern Nigeria. Demographic data were retrieved from case files, and fasting lipid profile and HbA<sub>1c</sub> levels were determined for all subjects. Lipid abnormalities were defined based on the Expert Panel on Integrated Guidelines for Cardiovascular Health Risk Reduction in Children and Adolescents. <b><i>Results:</i></b> Twenty-two subjects aged 7–18 years were studied (mean age: 14.94 ± 3.59 years). There were 12 (54.5%) females. Both genders were comparable regarding age (<i>p</i> = 0.95). Mean duration of diabetes was 3.37 ± 2.38 years. Prevalence of lipid abnormalities include: hypertriglyceridaemia (86.4%), hypercholesterolemia (22.7%), abnormal HDL-C (36.4%), high LDL-C (13.6%), and non-HDL-C (22.7%). Hypercholesterolaemia was significantly higher in females (<i>p</i> = 0.02), and prevalence of hypertriglyceridaemia was higher in subjects ≥12 years (<i>p</i> = 0.019). There was no statistically significant difference in mean levels of various lipids between males and females. Six (27.3%) subjects had more than one lipid abnormality. There was no statistically significant association of lipid abnormalities with age, sex, weight category, and HbA<sub>1c</sub> level. <b><i>Conclusion:</i></b> The commonest lipid abnormality was hypertriglyceridaemia. About a quarter of the subjects had more than 1 lipid abnormality. Programs should therefore be targeted at improved control of glycemia and lipid levels to delay and prevent chronic complications.

JOURNAL OF EDUCATION AND HEALTH PROMOTION 2019; 8:6. [PMID: 30815477 PMCID: PMC6378828 DOI: 10.4103/jehp.jehp_194_17] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 12/27/2017] [Accepted: 06/14/2018] [Indexed: 05/12/2023]
Abstract
BACKGROUND Type 1 diabetes mellitus (T1DM) and its related comorbidities are considered an important health issue. This study aimed to evaluate the impact of glycemic control on lipid profile variables in children with T1DM. MATERIALS AND METHODS This study included 274 children (≤19 years of age) with T1DM who had referred to the outpatient clinics of endocrinology in Emam-Hossein Hospital of Isfahan, Iran. Based on American Diabetes Association criteria, patients were divided into two groups including optimal glycemic control (OGC) and poor glycemic control (PGC). Mean lipid level and frequencies of lipid profile abnormalities between the two studied groups were compared. RESULTS Mean age of the studied population was 13 ± 5.9 years and 133 (48.5%) were boys. A total of 162 (59.1%) and 112 (40.9%) patients had PGC and OGC, respectively. Hypercholesterolemia was the most common dyslipidemia in both groups (33 [29.1%] of OGC and 63 [39.1%] of PGC patients). The frequency of high low-density lipoprotein (LDL) was significantly higher in patients with PGC than those with OCG (P = 0.007). The frequencies of hypercholesterolemia, hypertriglyceridemia, and low levels of high-density lipoprotein were also higher in PGC group, but did not reach the significant threshold. CONCLUSION It is suggested that glycemic control is in association with lipid profile abnormality in patients with T1DM. High LDL was significantly more frequent in patients with PGC than those with OGC. It is recommended to investigate the role of glycemic control on other cardiometabolic risk factors of T1DM patients. Our findings could be used for planning preventative strategies for reducing T1DM-related cardiovascular disease.

Children with type 1 diabetes who experienced a honeymoon phase had significantly lower LDL cholesterol 5 years after diagnosis. PLoS One 2018; 13:e0196912. [PMID: 29768449 PMCID: PMC5955510 DOI: 10.1371/journal.pone.0196912] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2017] [Accepted: 04/23/2018] [Indexed: 01/12/2023] Open
Abstract
Importance Landmark studies showed that partial clinical remission in new-onset type 1 diabetes is associated with reduced prevalence of long-term complications, but early clinical indicators of this favorable outcome are poorly characterized. Aim To determine if there were any differences in lipid parameters, especially LDL-cholesterol, between remitters and non-remitters 4 to 5 years after the diagnosis of type 1 diabetes after controlling for hemoglobin A1c, body mass index, and pubertal status. Subjects and methods A longitudinal retrospective cohort study of 123 subjects of mean age 11.9 ± 2.9 years, [male 11.7 ± 2.9 years, (n = 55); female 12.0 ± 2.9 years, (n = 68), p = 0.60] with type 1 diabetes of 4–5 years duration. Anthropometric and biochemical data were collected at the 4th or 5th year after diagnosis in line with the American Diabetes Association recommendation to initiate screening for complications in children either at the beginning of puberty or 4–5 years after diagnosis. Puberty was defined by Tanner stages II-V. Partial clinical remission was defined by the gold-standard insulin-dose adjusted hemoglobin A1c (IDAA1c) of ≤9. Results There were 44 (35.8%) remitters (age 13.0 ± 2.5y; male 52.3%). Both the total cholesterol and LDL-cholesterol were significantly lower in remitters compared to non-remitters: LDL-C: 78.8 ± 28.7 mg/dL vs. 91.6 ± 26.5 mg/dL, p = 0.023; and total cholesterol: 151.5 ± 32.6 mg/dL vs. 167.0 ± 29.6 mg/dL, p = 0.015. Other lipid fractions were similar between the groups. There were no differences between the groups for glycemic control, body mass index z score, thyroid function, celiac disease occurrence, or vitamin D status. A greater number of remitters were in puberty compared to non-remitters (86.4% vs. 60.8%, p = 0.006). LDL-C concentration was similar in prepubertal remitters vs. non-remitters (p = 0.93), but was significantly lower in remitters in puberty compared to non-remitters in puberty (p = 0.018) after adjusting for age and duration of diabetes. Conclusions Children with type 1 diabetes who underwent a honeymoon phase had significantly lower LDL cholesterol 5 years after diagnosis. This early divergence in lipidemia may explain the dichotomy in the prevalence of long-term complication in type 1 diabetes between remitters and non-remitters. It also offers a pathway for targeted lipid monitoring in type 1 diabetes, by establishing non-remission as a non-modifiable risk factor for vascular complication in type 1 diabetes.

Abstract
BACKGROUND Insulin resistance (IR) is an important clinical issue in patients with type 1 diabetes due to worse metabolic control and risk of development of chronic complications. OBJECTIVE The aim of the study was to evaluate simple and easily available parameters as indirect markers of IR in adults with type 1 diabetes and correlate it with the results of hyperinsulinemic-euglycemic clamp. METHODS The study included 88 patients (62 men), aged 34.1 ± 6.5 years, with type 1 diabetes with a median disease duration of 8 (7-13) years and mean HbA1c of 7.6 ± 1.5%. Tissue sensitivity to insulin was assessed on the basis of glucose distribution rate (GDR) obtained in the course of hyperinsulinemic-euglycemic clamp. In addition, indirect markers of IR, such as estimated GDR, presence of features of metabolic syndrome, visceral adiposity index (VAI), and the triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C) ratio, were evaluated. RESULTS In the study group, IR defined as GDR <4 mg/kg/min was observed in 33 (37.5%) patients. Group with IR had significantly higher postprandial glycemia (9.1 ± 2.0 vs 8.4 ± 1.1 mmol/L, P = .04), serum TG level (1.11 [0.75-1.92] vs 0.85 [0.60-1.08] mmol/L, P = .001), lower HDL-C level (1.59 ± 0.38 vs 1.8 ± 0.5 mmol/L, P = .02), higher TG/HDL-C ratio (1.60 [1.00-3.13] vs 1.05 [0.62-1.53], P = .001), and higher VAI (2.61 [1.31-4.25] vs 1.56 [0.96-2.25], P = .002). Significant relationship between GDR and TG/HDL-C ratio and VAI, adjusted for age, sex, HbA1c, and duration of diabetes was revealed (respectively, odds ratio 1.90 [95% confidence interval 1.15-3.15], P = .01 and odds ratio 1.47 [95% confidence interval 1.06-2.04], P = .01). CONCLUSIONS TG/HDL-C ratio and VAI appear to be clinically useful tools to assess IR in adults with type 1 diabetes.

Abstract
BACKGROUND Dyslipidemia increases the frequency and severity of micro and macrovascular complications of type 1 diabetes (T1D). The present study aims to determine the prevalence of dyslipidemia and its association with clinical and laboratory findings in diabetic children and adolescents. METHODS The study included 202 children and adolescents with T1D. Demographic data and laboratory findings were obtained from patients files. RESULTS Dyslipidemia prevalence was found to be 26.2%. Hypercholesterolemia (15.8%) and hyperglyceridemia (12.9%) were most common findings. Age, body mass index (BMI), hemoglobin A1c (A1C) and poor metabolic control were significantly higher in cases with dyslipidemia. Smoking rate was 14.1% in the pubertal group. Poor metabolic control and dyslipidemia was found higher among smokers (p<0.05). CONCLUSIONS Blood lipid levels should be monitored regularly and nutrition education should be repeated periodically to prevent and control dyslipidemia in patients with T1D. Smoking-related risks should be a part of patient education in the pubertal period.

Abstract
AIMS The aim of this study was to assess the arterial stiffness in patients with type 1 diabetes compared with a control group and determine the associated potential risk factors for its occurrence. METHODS Fifty-seven subjects with type 1 diabetes and fifty-three healthy controls were submitted to clinical and laboratory evaluation. The peripheral waveform pressure was analyzed to assess arterial stiffness according to the reflection and stiffness index. RESULTS Arterial stiffness did not differ between the controls and patients with type 1 diabetes. Pulse pressure showed no difference among both groups. In the group of patients with type 1 diabetes, the stiffness index was correlated with diabetes duration (r = 0.59, p < 0.001), body mass index (r = 0.27, p = 0.03), diastolic blood pressure (r = 0.33, p = 0.001), triglycerides (r = 0.35, p = 0.007), and age (r = 0.46, p < 0.001). The reflection index was correlated with the systolic blood pressure (r = 0.29, p = 0.02), diastolic blood pressure (r = 0.30, p = 0.02), and cardiac frequency (r = 0.48, p < 0.001). In the stepwise multivariate analysis, disease duration, diastolic blood pressure, and HDL cholesterol were the most important independent variables associated with arterial stiffness in patients with type 1 diabetes. CONCLUSIONS We concluded that in the studied population, arterial stiffness showed no difference between patients with diabetes and controls; thus, the use of this method should not be indicated for routine clinical practice in type 1 diabetes.

Abstract
OBJECTIVE The association between type 1 diabetes mellitus (T1D) and dyslipidemia (DLP) increases the risk of cardiovascular disease (CVD). The aim of this study was to evaluate the presence of dyslipidemia in young T1D patients. MATERIALS AND METHODS The study design was cross-sectional and descriptive. We reviewed medical records of T1D patients followed at an endocrinology service, from 1998-2012. DATA COLLECTED gender, actual age and age at diagnosis, duration of T1D since diagnosis, body mass index (BMI), pubertal stage, glycemic control (GC) determined by glycated hemoglobin (HbA1c), total cholesterol (TC), HDL, LDL, triglycerides (TG). To analyze lipid profile and metabolic control, we used the Brazilian Society of Diabetes Guidelines. RESULTS Were included 239 T1D patients, 136 (56.9%) females; mean ± SD: actual age 15.7 ± 5.0 years and at T1D diagnosis 7.3 ± 3.9; T1D duration 10.6 ± 6.4 years, 86.6% puberty, 15.1% overweight. The prevalence of DLP was 72.5%, 63.3% females, 86.6% puberty, mean ± SD: actual age 15.4 ± 4.8 years and at T1D diagnosis 7.2 ± 4.1 years, duration of T1D 10.7 ± 6.1 years. We found high-CT in 56.7%, low-HDL = 21.7%, high LDL = 44.0%, high-TG = 11.8%. Between females with DLP, 83.5% was in puberty. We find correlation between the presence of DLP, a poor GC and BMC. CONCLUSION We found a high prevalence of DLP in young patients with T1D, particularly in puberty females. Programs targeting the prevention of dyslipidemia should be adopted, especially for this group, in order to prevent/delay chronic complications and cardiovascular disease.

Double-diabetes in a real-world sample of 2711 individuals: associated with insulin treatment or part of the heterogeneity of type 1 diabetes? Diabetol Metab Syndr 2016; 8:28.

Abstract
BACKGROUND Double diabetes (DD) describes both individuals with obesity upon diagnosis of type 1 diabetes and those who have gained weight during follow-up, although cardiovascular risk factors (CVRF) are not well understood in this group. We aim to evaluate the frequency of DD in a real-world type 1 diabetes sample and the interaction of insulin treatment with CVRF. METHODS Multicentre cross-sectional study of 2711 individuals with clinical diagnosis of type 1 diabetes from secondary diabetes centres in 20 Brazilian cities. RESULTS Patients with diabetes duration <5 and ≥5 years had similar frequency of overweight (20.4 vs. 25 %) and obesity, (9.8 vs. 6.1 %), p 0.28 for trend. Insulin dose (U/kg/day) was lower in obese individuals compared to normal BMI, with mean (95 % CI) 0.72 (0.62-0.83) vs. 0.88 (0.84-0.92) U/kg/day for diabetes duration <5 years and 0.84 (0.77-0.92) vs. 0.99 (0.97-1.01) U/kg/day for duration ≥5 years. Obese individuals had lower HDL (47.5 vs. 54.4 mg/dL) and higher non-HDL-cholesterol (134.5 vs. 115.2 mg/dL) than lean ones only among those with more than 5 years of diabetes. CONCLUSIONS Lower insulin doses in obese individuals point to a role of clinical heterogeneity in insulin deficiency rather than normal progression of type 1 diabetes. Early obesity in type 1 diabetes is associated to lower HDL-cholesterol and higher number of CVRF. These data suggest a broad landscape of pathophysiological phenomena in double diabetes, rather than simple progression of a homogeneous clinical entity.

Abstract
The blood serum lipid profile of women with Gestational Diabetes Mellitus (GDM) is still under study. There are no data on the serum lipid profile of GDM patients with more severe (insulin treated) compared to milder forms (diet treated) GDM. The aim of our study was to analyze the blood serum lipid profile of patients with milder versus more severe forms of GDM and to compare these findings with those of healthy pregnant women. This cross-sectional analytical study included 30 insulin-treated GDM, 30 diet-only GDM and 30 healthy pregnant women. Serum lipid was extracted from the 90 participants and their lipid profiles were analyzed by lipid fingerprinting using liquid-chromatography-mass spectrometry. A total of 143 parent ions were differentially represented in each of the three groups, belonging to the following classes: Glycerophospholipids, Sterol Lipids, Sphingolipids, Prenol Lipids, Fatty Acyls and Glycerolipids. There were significant differences in the lipid profiles of healthy pregnant women compared to GDM patients and also between milder versus more severe forms of GDM. There are marked differences in lipid fingerprinting between healthy pregnant women compared to those with GDM in the third trimester. Moreover, the lipid profile of women with more severe forms of GDM differs considerably from that of women with milder forms of GDM. These findings may be useful to help clarify the pathogenesis of milder and more severe forms of GDM.

DeBoer MD, Gurka MJ. Low sensitivity of the metabolic syndrome to identify adolescents with impaired glucose tolerance: an analysis of NHANES 1999-2010. Cardiovasc Diabetol 2014; 13:83. [PMID: 24755002 PMCID: PMC4000320 DOI: 10.1186/1475-2840-13-83] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2014] [Accepted: 04/15/2014] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND The presence of impaired glucose tolerance (IGT) and metabolic syndrome (MetS) are two risk factors for Type 2 diabetes. The inter-relatedness of these factors among adolescents is unclear. METHODS We evaluated the sensitivity and specificity of MetS for identifying IGT in an unselected group of adolescents undergoing oral glucose tolerance tests (OGTT) in the National Health and Nutrition Evaluation Survey 1999-2010. We characterized IGT as a 2-hour glucose ≥140 mg/dL and MetS using ATP-III-based criteria and a continuous sex- and race/ethnicity-specific MetS Z-score at cut-offs of +1.0 and +0.75 standard deviations (SD) above the mean. RESULTS Among 1513 adolescents, IGT was present in 4.8%, while ATP-III-MetS was present in 7.9%. MetS performed poorly in identifying adolescents with IGT with a sensitivity/specificity of 23.7%/92.9% for ATP-III-MetS, 23.6%/90.8% for the MetS Z-score at +1.0 SD and 35.8%/85.0 for the MetS Z-score at +0.75 SD. Sensitivity was higher (and specificity lower) but was still overall poor among overweight/obese adolescents: 44.7%/83.0% for ATP-III-MetS, 43.1%/77.1% for the MetS Z-score at +1.0 SD and 64.3%/64.3% for MetS Z-score at +0.75 SD. CONCLUSION This lack of overlap between MetS and IGT may indicate that assessment of MetS is not likely to be a good indicator of which adolescents to screen using OGTT. These data further underscore the importance of other potential contributors to IGT, including Type 1 diabetes and genetic causes of poor beta-cell function. Practitioners should keep these potential causes of IGT in mind, even when evaluating obese adolescents with IGT.

Abstract
The aim of this study was to evaluate subclinical atherosclerosis and related factors in young type 1 diabetes (T1D) patients and healthy peers. Carotid intima-media thickness (cIMT) and anthropometric/laboratorial data were obtained for 83 T1D patients (mean age 19.5 ± 4.0 years, disease duration 9.8 ± 4.8 years) and for 36 matched healthy subjects. Considering all the participants as one group, male sex (p = 0.008), weight (p = 0.016) and T1D (p < 0.001) were positively associated with a higher cIMT. High-density lipoprotein (HDL) (p = 0.036) was negatively associated with cIMT in T1D. In the male T1D patients, HDL ≤47.5 mg/dL had a sensitivity of 87.5% and specificity of 57% (p = 0.035) in detecting those belonging to a higher cIMT tercile. In conclusion, weight and T1D were associated with increased cIMT. HDL levels ≤47.5 mg/dL were related to a higher cIMT in male T1D patients.

Abstract
The presence of cardiovascular disease (CVD) in Type 1 diabetes largely impairs life expectancy. Hyperglycemia leading to an increase in oxidative stress is considered to be the key pathophysiological factor of both micro- and macrovascular complications. In Type 1 diabetes, the presence of coronary calcifications is also related to coronary artery disease. Cardiac autonomic neuropathy, which significantly impairs myocardial function and blood flow, also enhances cardiac abnormalities. Also hypoglycemic episodes are considered to adversely influence cardiac performance. Intensive insulin therapy has been demonstrated to reduce the occurrence and progression of both micro- and macrovascular complications. This has been evidenced by the Diabetes Control and Complications Trial (DCCT) / Epidemiology of Diabetes Interventions and Complications (EDIC) study. The concept of a metabolic memory emerged based on the results of the study, which established that intensified insulin therapy is the standard of treatment of Type 1 diabetes. Future therapies may also include glucagon-like peptide (GLP)-based treatment therapies. Pilot studies with GLP-1-analogues have been shown to reduce insulin requirements.

Abstract
Background Little is known about the impact of sex-specific differences in the management of type 1 diabetes (T1DM). Thus, we evaluated the influence of gender on risk factors, complications, clinical care and adherence in patients with T1DM. Methods In a cross-sectional study, sex-specific disparities in glycaemic control, cardiovascular risk factors, diabetic complications, concomitant medication use and adherence to treatment recommendations were evaluated in 225 consecutive patients (45.3% women) who were comparable with respect to age, diabetes duration, and body mass index. Results Although women with T1DM had a higher total cholesterol than men, triglycerides were higher in obese men and males with HbA1c>7% than in their female counterparts. No sex differences were observed in glycaemic control and in micro- or macrovascular complications. However, the subgroup analysis showed that nephropathy was more common in obese men, hyperlipidaemic women and all hypertensive patients, whereas peripheral neuropathy was more common in hyperlipidaemic women. Retinopathy was found more frequently in women with HbA1c>7%, obese men and in both sexes with a long duration of diabetes. The multivariate analysis revealed that microvascular complications were associated with the duration of disease and BMI in both sexes and with hyperlipidaemia in males. The overall adherence to interventions according to the guidelines was higher in men than in women. This adherence was concerned particularly with co-medication in patients diagnosed with hypertension, aspirin prescription in elderly patients and the achievement of target lipid levels following the prescription of statins. Conclusions Our data showed sex differences in lipids and overweight in patients with T1DM. Although glycaemic control and the frequency of diabetic complications were comparable between the sexes, the overall adherence to guidelines, particularly with respect to the prescription of statins and aspirin, was lower in women than in men.

Abstract
Patients with diabetes frequently exhibit the combined occurrence of hyperglycemia and dyslipidemia. Published data on their coexistence are often controversial. Some studies provide evidence for suboptimal lifestyle and exogenous hyperinsulinism at "mild insulin resistance" in adult diabetic patients as main pathogenic factors. In contrast, other studies confirm that visceral adiposity and insulin resistance are the basic features of dyslipidemia in type 2 diabetes (T2D). The consequence is an excess of free fatty acids, which causes hepatic gluconeogenesis to increase, metabolism in muscles to shift from glucose to lipid, beta-cell lipotoxicity, and an appearance of the classical "lipid triad", without real hypercholesterolemia. Recently, it has been proposed that cholesterol homeostasis is important for an adequate insulin secretory performance of beta-cells. The accumulation of cholesterol in beta-cells, caused by defective high-density lipoprotein (HDL) cholesterol with reduced cholesterol efflux, induces hyperglycemia, impaired insulin secretion, and beta-cell apoptosis. Data from animal models and humans, including humans with Tangier disease, who are characterized by very low HDL cholesterol levels, are frequently associated with hyperglycemia and T2D. Thus, there is a reciprocal influence of dyslipidemia on beta-cell function and inversely of beta-cell dysfunction on lipid metabolism and micro- and macrovascular complications. It remains to be clarified how these different but mutually influencing adverse effects act in together to define measures for a more effective prevention and treatment of micro- and macrovascular complications in diabetes patients. While the control of circulating low-density lipoprotein (LDL) cholesterol and the level of HDL cholesterol are determinant targets for the reduction of cardiovascular risk, based on recent data, these targets should also be considered for the prevention of beta-cell dysfunction and the development of type 2 diabetes. In this review, we analyze consolidated data and recent advances on the relationship between lipid metabolism and diabetes mellitus, with particular attention to the reciprocal effects of the two features of the disease and the development of vascular complications.
