LUIS, D. A. de et al. Descriptive study of onset diabetes mellitus type 1 patients and first degree families. An. Med. Interna (Madrid) [online]. 2004, vol.21, n.8, pp.20-23. ISSN 0212-7199.

Background: Few information about descriptive studies of autoimmunity in diabetes mellitus type 1 onset patients and family exist. The aim of our study was to analyze clinical and biochemical parameters of onset diabetes mellitus type 1 patients and first degree families. Patients and methods: Forty seven onset diabetes mellitus type 1 patients and 148 first degree families were studied, between January 1999 and December 2002, in the west area of Valladolid. In all cases and families an anthropometric study and biochemical determination with autoimmunity levels were performed. Results: Average age in onset diabetes mellitus type 1 patients was 16.09 (9.36) years, without differences between males (32 cases, 68%) and females (15 cases, 32%), with an incidence of 4.66 cases/100,000 habs./year. Average values of peroxidase antibodies (antiPTO) and glutamic descarboxilase antibodies (antiGAD) were higher in diabetic patients than in families. No differences were detected in insulin antibodies (IAA) and tiroglobuline antibodies (antiTG). No correlation was detected between anti TPO and anti pancreas. Autoantibodies did not influence in glycemic control. Average dose of NPH insulin and regular insulin were 27.58 (13.88) UI/d y 3.05 (4.90) UI/d, respectively. Conclusions: Average age of onset diabetes mellitus type 1 patients was similar than other studies, with a high frequency of males. VAlues of antiGAD y antiTPO were higher in diabetic patients than families. No correlation between autoimmunity and glycemic control was detected.
