The increased incidence of a enterovirus infections observed in patients with type 1 diabetes preceding the development of the clinical disease could be partially explained by variation in the genes coding for enterovirus receptors. We carried out sequence analysis of the most common enterovirus receptor molecules in 21 diabetic children and 20 healthy adults. DNA was isolated from the leukocytes, and gene regions known to code for virus-recognizing domains in major enterovirus receptors were amplified and sequenced. Heterozygous single-nucleotide polymorphism (SNP), Ala 67 (GCG) --> Thr (ACG), was detected in the poliovirus receptor gene in four individuals in the diabetes group, but not in the control group. However, serological studies could not confirm that this substitution would convey different susceptibility to poliovirus infection. A heterozygous SNP, Lys 29 (AAG) --> Met (ATG), was found in the intracellular adhesion molecule-1 (ICAM-1) (receptor for rhinoviruses and some coxsackie A viruses) in one individual in both groups. A silent SNP in the alpha2 integrin subunit gene (echovirus 1 receptor) was frequently found in both groups, a silent heterozygotic SNP in coxsackievirus-adenovirus receptor (coxsackie B virus receptor) gene was seen in one individual in the diabetes group, whereas no variation was found in the DAF (echovirus receptor) and beta3 integrin subunit sequences (receptor for coxsackievirus A9) studied. In conclusion, both synonymous and nonsynonymous sequence variability of genes coding for enterovirus and rhinovirus receptors was shown to occur, but no pattern directly specific for type 1 diabetes was found. =

Psychological aspects and patients' acceptance of type 1 diabetes (DM1) may exercise some influence in their glycemic control. In this project the influence of psychological aspects were evaluated on glycemic control of DM1 patients. A retrospective study of participants from Diabetes Weekend (DW), an educational project in DM1 was carried out in Minas Gerais. In a sample of 150 subjects (66M/84F, 21.6+/-13.5 years and duration of DM of 8.5+/-7.9 years) we analyzed: type of insulin, insulin delivery, insulin dose per day and insulin dose per day in DW, psychological profile, capillary glycemia and previous history of convulsion crisis, severe hypoglycemia or diabetic ketoacidosis (CAD). Glucose was monitored 4 times a day by a digital glucose monitor. 20.9% of the patients with DM1 felt very well (G1); 39.5% well (G2), 25.6% with difficult glycemic control (G3), 9.3% trying to accept (G4) and 4.7% reported to be very bad about their DM1. The average capillary glycemia (ACG, in mg/dl) was significantly lower in G1 than in the others (169.8; G2: 182.3; G3: 199.3; G4: 200.7). There were no significant association of this psychological aspects and previous history of CAD, hypoglycemia or convulsion crisis. DM1 duration over 5 years was associated to lower acceptance of the disease (p= 0.017) and age of patients (p= 0.000). 13.9% of patients reported to be ashamed of their disease; the ACG was significantly higher in this group as compared to others (246.2 vs. 178.1; p= 0.007). In 91 patients (60.4%) who mention to have apprehension of feeling sick in public the ACG was significantly higher (200.4 vs. 184.5; p= 0.014). The systematic glucose monitoring showed positive association between psychological aspects and worse glycemic control. The psychological and multidisciplinary approach of DM1 patients is very important to try to improve the metabolic control, to prevent future complications, which results in better quality of life for these patients.

In addition to HLA and insulin genes, the costimulatory molecule CTLA-4 gene is a confirmed type 1 diabetes (T1D) susceptibility gene. Previous studies investigated the association of CTLA-4 genetic variants with the risk of T1D, but with inconclusive findings. Here, we tested the contributions of common CTLA-4 gene variants to T1D susceptibility in Tunisian patients and control subjects. The study subjects comprised 228 T1D patients (47.8% females) and 193 unrelated healthy controls (45.6% females). Genotyping for CTLA-4 CT60A/G (rs3087243), +49A/G (rs231775), and -318C/T (rs5742909) was performed by PCR-restriction fragment length polymorphism (RFLP) analysis. The minor-allele frequencies (MAF) for the three CTLA-4 variants were significantly higher in T1D patients, and significantly higher frequencies of homozygous +49G/G and homozygous CT60G/G genotypes were seen in patients, which was confirmed by univariate regression analysis (taking the homozygous wild type as a reference). Of the eight possible three-locus CTLA-4 haplotypes (+49A/G, -318C/T, and CT60A/G) identified, multivariate regression analysis confirmed the positive association of ACG (odds ratio [OR], 1.93; 95% confidence interval [CI], 1.26 to 2.94), GCG (OR, 2.40; 95% CI, 1.11 to 5.21), and GTA (OR, 4.67; 95% CI, 1.52 to 14.39) haplotypes with T1D, after confounding variables were adjusted for. Our results indicate that CTLA-4 gene variants are associated with increased T1D susceptibility in Tunisian patients, further supporting a central role for altered T-cell costimulation in T1D pathogenesis.

Glycogenic hepatopathy is excessive intrahepatic glycogen accumulation. It is a rare complication of long-standing, poorly controlled type 1 diabetes mellitus. We report a case of a 19-year-old woman with a history of poorly controlled diabetes mellitus and frequent admissions for diabetic ketoacidosis, who presented with abdominal pain, nausea, vomiting, and hepatomegaly. She was found to have diabetic ketoacidosis with persistently elevated serum lactate that did not improve with insulin infusions. She eventually underwent a liver biopsy, which showed excessive intracytoplasmic glycogen accumulation consistent with glycogenic hepatopathy.
