    ABSTRACT: The CTLA4 gene is involved in the activity of T cells. To determine the association between Graves' disease (GD) susceptibility and CT60 polymorphism of the CTLA4 gene. 189 children with GD and 620 healthy controls. We determined the genotype with restriction fragment length polymorphism and compared results. Genotype G/G was significantly associated with GD (odds ratio [OR] = 1.71, 95% confidence interval [CI] 1.20-2.44, Pc = 0.006); however, allele A could reverse its effect. Allele G was significantly more frequent (OR = 1.61, 95% CI 1.18-2.19, Pc = 0.0049) but allele A (OR = 0.62, 95% CI 0.46-0.85, Pc = 0.0049) and phenotype A (OR = 0.58, 95% CI 0.41-0.83, Pc = 0.006) were less frequent in patients with GD than in controls. The CT60 SNP was associated with susceptibility to GD. The G allele increased the risk of GD.

    ABSTRACT: The incidence of type 1 diabetes (T1D) is increasing rapidly worldwide, predominantly in younger individuals. We developed a checklist of all symptoms of T1D reported in the literature and compared the completeness of the recording of symptoms at initial presentation before and after the checklist was adopted. We retrospectively reviewed the records of patients newly diagnosed with T1D from January 1, 1979 through September 30, 2006 to assess the presenting features and test the usefulness of a symptom checklist in evaluating the history on presentation. The checklist was incorporated into the records as of October 1, 1994. Of the 304 patients identified, 130 (43%) had checklists in the charts. There were 146 (48%) boys, 98 (32%) who were diagnosed under the age of 6 years, and 198 (65%) presented with diabetic ketoacidosis (DKA). Records with a checklist noted diabetic symptoms that were subtle and easily ignored more often than records without the checklist. As compared with those diagnosed at an older age, patients diagnosed at < or = 6 years were more likely to be male, have DKA and a shorter symptom duration, and report more episodes of preceding viral infection and dyspnea. Patients with DKA also had a shorter symptom duration. A diabetic symptom checklist was helpful in identifying clinical diabetic symptoms and signs which were otherwise easily ignored. Younger children were more likely to have a shorter symptom duration and a higher incidence of DKA.

    ABSTRACT: Type 2 diabetes mellitus (T2DM) in children and adolescents is increasing in incidence worldwide. It is the leading type of newly diagnosed diabetes in Taiwan among school children. T2DM is associated with metabolic syndrome in adults, so we tried to find out if these metabolic disorders are present in children. From 1989 to 2003, 22 children and adolescents were diagnosed with T2DM in our hospital. Their ages ranged from 8.8 to 17.0 (11.7+/-2.3) years; 6 of them were boys. We compared their clinical characteristics with those of 42 healthy and 237 obese children and adolescents. Physical examination was performed and plasma glucose and serum cholesterol, triglycerides, uric acid, creatinine, HDL-cholesterol, and insulin levels were measured and LDL-cholesterol was calculated. Demographic and laboratory data were compared among the T2DM, obese and control groups. The female: male ratio among the patients was 2.7: 1; 18% were overweight and 68% obese, and 64% had acanthosis nigricans. There were no significant differences between the T2DM and obese groups in terms of biochemistry profiles except for the higher plasma glucose in the T2DM group. Children with T2DM had higher levels of cholesterol and triglycerides but lower levels of HDL-cholesterol compared with healthy children. Among obese children without T2DM, the levels of glucose, triglycerides, uric acid, insulin, HOMA-IR were higher than in the healthy group, and HDL-cholesterol levels were lower. Children with T2DM or obesity should be evaluated for metabolic disorders.

    ABSTRACT: The CBLB gene functions as a negative regulator of autoimmunity. Impairment of the Cbl-b signaling pathway may contribute to human autoimmune disease. dbSNP rs2305035 is a C/T polymorphism located in exon 10 of the CBLB gene. We report an association study of this polymorphism in children with Graves' disease. The patients were 158 unrelated children (125 girls) with Graves' disease, aged 9.8 +/- 3.3 years. The controls consisted of 237 adults without a history of autoimmune disease. The C allele and phenotype frequencies of patients and controls were 247 (78.2%) vs 356 (75.1%) (OR = 1.19, p >0.05) and 151 (95.6%) vs 221 (93.2%) (OR = 1.56, p >0.05), respectively. The allelic polymorphism in patients and controls with and without DRB1*09012 were also not significantly different. This study demonstrates that the C/T polymorphism in exon 10 of the CBLB gene is not associated with Graves' disease in children.
