[Update on type 1 diabetes].

Type 1a diabetes develops from a chronic autoimmune process leading to absolute insulin deficiency and proneness to ketosis. Prospective studies have clearly shown that intensive insulin therapy (ICT) results in improved quality of life and reduced development of diabetes-associated microvascular and macrovascular complications. The gold standard of therapy in type 1 diabetes is insulin injection with a basal bolus insulin regimen, in which patient daily routine and wishes are considered. The treatment goals should be determined on an individualized basis together with the patient. An HbA(1c) value < 7.0% is considered to be well controlled while values ≤ 6.5% indicate an excellent blood glucose control, as long as there are no episodes of severe hypoglycemia. As many adult patients with type 1 diabetes develop additional cardiovascular risk factors dyslipidemia and hypertension should also be considered and treated according to current treatment guidelines. A multimodal treatment may be the best way to preserve quality of life in patients with type 1 diabetes.
