Szepietowska B, Szelachowska M, Gorska M, Jakubczyk D, Kinalska I: [Chronic complications in adult patients with newly diagnosed diabetes mellitus in relation to the presence of humoral autoimmune markers against pancreatic islet cells]. Pol Arch Med Wewn. 2004 May;111(5):563-9.
Latent autoimmune diabetes in adults (LADA) is subtype of diabetes type 1. It is well know, that 50% patients with new diagnosed diabetes type 2 present late complications. As far we don't know how many patients with new diagnosed diabetes have late complications according to presence of antibodies against islet antigens. The aim of the study was to compare late complications of diabetes: microangiopathy and macroangiopathy in newly diagnosed adult diabetic patients in relation to presence of humoral autoimmune markers. MATERIAL AND METHODS: We evaluated the presence of late complications in group of 41, hospitalized patients base on clinical examination and medical history. Glutaminic acid decarboxylase antibodies (anti-GAD), protein tyrosine phosphatase antibodies (anti-IA-2) and anti-insulin antibodies (IAA) titers were measured by RIA. The C peptide basal and stimulated, HbA1c, glucose, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, urea, creatinine levels and microalbuminuria were evaluated. RESULTS: The presence of islet cell specific antibodies were shown in 25 subjects. We observed late complications in 13/25 (52%) in group with positive antibodies titers, and in 10/16 (62.5%) in group without antibodies. We diagnosed the nephropathy (16% vs 6.25%), retinopathy (12% vs 0%), polyneuropathy (20% vs 12.5%), hypertension (32% vs 50%), chronic heart disease (8% vs 25%), overweight (32% vs 50%) and hyperlipidemia (12% vs 25%) respectively in subjects with and without antibodies. The concentrations of total cholesterol (185 +/- 47.8 vs 218 +/- 38.7, p < 0.05) and creatinine level (0.8 +/- 0.15 vs 0.95 +/- 24, p < 0.05) were higher in group without antibodies, but fasting glycemia (181 +/- 69.1 vs 132 +/- 32.8, p < 0.05) was higher in the group presenting with autoantibodies. We did not observed the difference between level of glycosylated hemoglobin in the investigated groups. RESULTS: There is the tendency to higher incidence of microangiopathy in group of patients positive to islet cell antibodies. Conversely the macroangiopathy appears frequently in patients without antibodies. |
