Background:
Diabetes mellitus type 1 is the most common endocrine metabolic disorder occurring in childhood and adolescence due to the autoimmune destruction of pancreatic beta cells as a result of various environmental factors interacting with an underlying genetic predisposition. Diabetes is a risk factor for early onset atherosclerosis, and the high mortality rate seen in these patients is partially related to cardiovascular diseases.Objectives:
This study was conducted to compare mean platelet volume as a marker of early atherosclerosis with aortic intima-media thickness in children with type 1 diabetes and to identify its correlation with known cardiovascular risk factors.Patients and Methods:
The study included 27 patients between age range of 6 and 17 years that were diagnosed with type 1 diabetes and 30 healthy children of the same age range who did not have any chronic disease. In both groups, we used the color Doppler ultrasound to measure children’s aortic intima-media thickness and identify their mean platelet volumes.Results:
There was no significant difference between the groups regarding gender distribution, age, High-Density Lipoprotein (HDL) and Low-Density Lipoprotein (LDL) cholesterol levels (P > 0.05). Also no significant difference could be documented between the patient and control groups regarding the aortic intima-media thickness and mean platelet volume (P > 0.05). However, there was a significant correlation between aortic intima-media thickness and mean platelet volume (r = 0.351; P < 0.05).Conclusions:
In the present study, there was no evidence of early atherosclerosis in children with type 1 diabetes. However, mean platelet volume having a significant correlation with aortic intima-media thickness may be useful as an early marker of atherosclerosis. 相似文献2.

We studied ICA, HLA and insulin secretory capacity in 87 children with positive urinary screening and more than 2 points in the oral glucose tolerance test in order to establish criteria by which they could be classified into type 1 or type 2 diabetes mellitus. Fifty-five non-obese, ketosis-prone insulin dependent diabetic children were used as controls for type 1 diabetes mellitus. Our conclusions were as follows: 1. Type 1 diabetics were non-obese (on insulin therapy), ICA positive, ketosis-prone, had an insulin secretory capacity (Z IRI) of less than 100/nU/ml, and most of them possessed HLA-Bw54-DR4 or DRw9, DRw53 but did not possess Bw52-DR2 haplotype. 2. In the patients who were treated by dietary regimens alone for certain periods, however, insulin secretory capacities gradually deteriorated and they finally became insulin dependent. The children of this group who were not obese during insulin therapy and possessed an HLA haplotype identical to that in type 1 diabetes, regardless of ICA, might be classified as having slowly progressive type 1 diabetes. 3. The major difference between type 1 and slowly progressive type 1 diabetes was a family history of diabetes. Genetic factors might modify the clinical course of type 1 diabetes mellitus. 4. If the sensitivity of ICA or related autoantibodies to islet cells can be detected more readily, it should become easier to distinguish between type 1 and 2 diabetes. 相似文献

Objective
Adiponectin is secreted from adipose tissue. This hormone has a fundamental role in pathogenesis of insulin resistance, and has anti-inflammatory and anti-atherogenic effects. The objectives of this study were to compare serum adiponectin level between type 1 diabetics and healthy people and to assess its related factors, and also to determine the relationship between adiponectin and metabolic state.Methods
This was a case control study involving 60 diabetics (25 good and 35 poor metabolic controlled) and 28 healthy persons (younger than 18 years old). The data about demographic (age and sex), clinical and paraclinical characteristics [body mass index (BMI), duration of disease, puberty state, and glycosylated hemoglobin (HbA1c) and adiponectin level in serum] were collected. Determinants of adiponectin were assessed using univariate and multiple linear regression analyses.Findings
Mean (±SD) serum adiponectin level in healthy persons, good-controlled and poor-controlled type 1 diabetes mellitus patients were 9.16 (±4.2) µg/cc, 10.89 (±4.48)µg/cc, and 15.92 (±8.26)µg/cc, respectively. Post hoc analysis revealed that differences of adiponectin between poor- and good-controlled type 1 diabetes mellitus patients (P=0.01) and between healthy persons and poor controlled type 1 diabetes mellitus (P<0.0001) were statistically significant. Adiponectin level was associated with puberty state and BMI in healthy persons. It was associated with puberty state and HbA1c in type 1 diabetic persons.Conclusion
Serum level of adiponectin was higher in type 1 diabetics than in healthy persons and it can be used as a good marker for metabolic control state among diabetics. 相似文献4.

Objective
Studies in different populations have shown great variation in the prevalence of thyroid diseases in patients with type 1 diabetes mellitus (T1DM). Our aim was to study the prevalence of thyroid disorders such as autoimmunity of thyroid (AIT), thyroid dysfunction, and goiter in children and adolescents with T1DM, compared with age- and sex-matched healthy controls in Isfahan.Methods
One hundred patients with T1DM who were referred to Isfahan Endocrine and Metabolism Research Center and 184 healthy schoolchildren matched for age and sex were included. They were examined for goiter by two endocrinologists. Thyroid function test and serum thyroid antibodies (anti-TPO Ab and anti-Tg Ab) were measured.Findings
The prevalence of subclinical hypothyroidism was high in both groups (18%). T1DM patients had lower frequency of goiter (21% vs. 38%, P=0.001), and higher prevalence of positive AIT (22% vs. 8%, P=0.001), anti-TPO Ab positivity (19.3% vs. 5.3%, P=0.000), and anti-Tg Ab (11.1% vs. 6.4%, P=0.1) in comparison with the control group. Being positive for AIT in diabetic patients meant an odds ratio of 5 (CI 95%: 1.5-15.6) for thyroid dysfunction. There was no association between age, sex, duration of diabetes and HbA1C with serum anti-TPO Ab and anti-Tg Ab concentrations in this group.Conclusion
Our results demonstrated the high prevalence of AIT and thyroid dysfunction in patients with T1DM. We suggest regular thyroid function and antibody testing in these patients. 相似文献7.
目的探讨近年新诊断儿童1型糖尿病的临床特征。方法对1999年1月1日~2005年4月30日浙江大学医学院附属儿童医院住院且为首次发病的109例1型糖尿病的临床资料进行回顾性分析,按照有无酮症酸中毒和有无低钾血症分别进行分组比较,正态分布的数据用x±s表示,采用为卡方及t检验,非正态分布的资料用中位数表示,采用Mann-WhiteyU检验进行组间比较。结果新诊断1型糖尿病儿童非酮症酸中毒(DKA)组病程明显较DKA组长,平均住院时间和糖化血红蛋白明显低于DKA组。入院时有感染诱因者21例(19.3%);伴低钾血症48例(44%),非低钾血症61例(56%);DKA组低钾血症的比率为26/47(55.3%),明显高于非DKA组的22/62(35.5%)。低钾组出现心悸、胸闷及倦怠症状出现频率为39.6%、35.4%,而非低钾组上述症状的频率分别是11.5%、16.4%,两组差异有显著性。所有患儿无1例死亡,出院后治疗依从性不一致。结论感染可能导致患儿糖尿病的进展和临床表现的出现。低钾血症组的症状较重。可能是临床症状的不典型导致了糖尿病不能及时被发现。 相似文献

Clinical Significance of Urinary C-Peptide Excretion in Children with Insulin-Dependent Diabetes Mellitus 总被引:2,自引:0,他引:2
N.-P. HUTTUNEN M. KNIP M.-L. KÄÄR R. PUUKKA H. K. ÅKERBLOM 《Acta paediatrica (Oslo, Norway : 1992)》1989,78(2):271-277
ABSTRACT. In order to evaluate the accuracy of urinary C-peptide determination and the clinical significance of C-peptiduria for the early course of insulin-dependent diabetes (IDDM), the rate of urinary excretion of C-peptide was determined in 32 children and adolescents with IDDM and correlated with serum C-peptide concentration, urinary excretion of albumin and β-mic-rogloublin and with the glomerular filtration rate (GFR) measured in terms of the clearance of 99 mTc-DTPA. The age of the subjects ranged from 9.1 to 17.1 years (mean 13.1) and the duration of diabetes from 0.3 to 11.9 years (mean 4.6). There was a good correlation between postprandial serum C-peptide concentration and the 24-hour urinary C-peptide excretion rate ( r =0.81; p <0.001). GFR and urinary albumin excretion were slightly elevated in the diabetic patients as compared with non-diabetic subjects ( p <0.05 and p <0.001, respectively), but C-peptide excretion was unrelated to the degree of hyperfiltration or albuminuria, neither was there any correlation between the excretion rate of β2 -microglobulin and C-peptide. Glycaemic control was poorer in the diabetic children who had only trace amounts of C-peptide in their urine (<0.05 nmol/m2 /24 h) than in those with minimal (0.05–1.0 nmol/m2 ) or moderate 24-hour urinary C-peptide excretion (>1.0 nmol/m2 ). It is concluded that urinary C-peptide excretion serves very well to reflect residual β-cell function and is unrelated to the slight renal hyperfunction and albuminuria often seen in diabetic subjects. Even minimal C-peptide excretion ranging from 0.05 to 1.0 nmol/m2 /24 h still seems to indicate clinically significant insulin secretion. 相似文献

HLA, ICA (islet cell antibody) and autoantibodies were studied in 65 Japanese patients with type 1 diabetes mellitus to elucidate the existence of immuno-genetic heterogeneity. Patients with autoantibodies had increased frequencies of HLA DRw9 antigen and of HLA haplotype of Bw61-DRw9, and a slow decay of ICA, while patients without autoantibodies had increased frequencies of HLA DR4 antigen and of HLA haplotype of Bw54-DR4, and a rapid decay of ICA. These findings support the concept of immunogenetic heterogeneity in Japanese type 1 diabetes mellitus. 相似文献

DNA restriction fragment length polymorphism (RFLP) typing of HLA-DR and DQ alleles of 60 Japanese type 1 (insulin dependent) diabetic patients and 115 controls was performed. RFLP typing of DRB1 showed increased frequency of DR9 and decreased frequencies of DR2 and DRW6 among patients compared to controls. In the RFLP typing of BamHI- digested DNA to DQ β probe (BamHI-DQB1), the incidence of the 10.26 kb fragment, which represents either DQW4, DQW8 or DQW9, was markedly elevated in the patients, whereas the incidence of DQW6 was reduced. The predicted DR-DQ haplotype study revealed that DR4-DQW4 or DQW8, DRW8-DQW4 or DQW8 and DR9-DQW9 may contribute to susceptibility to type 1 diabetes. When serological typing of the 13 DRW8 patients was performed, all the 11 DRW8 patients carrying DQW4 or DQW8 (BamHI-10.26 kb) were positive for DQW3.
These results indicated that the HLA-DQ locus may play an important role in the development of type 1 diabetes in the Japanese as well as other ethnic groups and that the DRW8- DQW8 haplotype may predispose to the disease in Japan. 相似文献
