Latent autoimmune diabetes of the adult (LADA) is usually defined as a form of diabetes where the onset of diabetes takes place approximately after 30 years of age, where there is presence of beta-cell directed antibodies (mostly anti-GAD) and where there is no clinical need for insulin treatment during the first 6 months after the diagnosis of diabetes.
The aetiology and treatment of LADA patients is much less elucidated than is the case for type 1 diabetes (DM1) and type 2 diabetes (DM2). LADA constitutes about 10 % of the total diabetic population in many countries. LADA is therefore more common than insulin-requiring DM1.
LADA patients lose beta-cell function faster than patients with DM2. Residual beta-cell function in DM1 is coupled to better metabolic control with lesser degree of hyperglycemia, lesser frequency of hypoglycaemic events and lesser diabetic complications.
To retain beta-cell function in LADA patients is thus highly desirable.
There are several strategies to retain beta cell function. One therapeutic strategy is to induce some degree of "beta cell rest" by treatment with exogenous insulin. Several observations indicate that such a strategy can have beneficial effects.
This is a Scandinavian multicenter non-blinded clinical trial with 78 participants with newly diagnosed LADA. Participants will be randomized to either insulin- or per oral antidiabetic treatment. Participants will be followed up for 2 years after inclusion. Beta cell function and glycemic control will be monitored.

Active Comparator: Metformin + NPH Insulin
Patients are treated with metformin during the run-in period (3 months) and also after randomization. By randomization insulin treatment will be added in the form of injections of NPH insulin in the evenings.
Drug: metformin+ NPH insulin
Metformin 500 mg + 500 mg + 1000 mg NPH insulin , initially 0.20 U/kg body weight.
Active Comparator: Metformin + sitagliptin +/-repaglinid
Patients are treated with metformin during the run-in period (3 months) and also after randomization. By randomization sitagliptin tablets will be added.If HbA1c after 6 months of treatment is > 10 % above the upper limit of normal,then treatment with repaglinide tablets tree times daily at mealtimes will be added.
Drug: metformin + sitagliptin +/- repaglinide
Metformin 500 mg + 500 mg + 1000 mg Sitagliptin 100 mg x 1 Repaglinide 1 mg x 3
Other Name: Novonorm
- insulin secretion [ Time Frame: 2 years ]insulin secretion measured by fasting and glucagon-stimulated C-peptide
- glycemic control [ Time Frame: 2 years ]glycemic control (HbA1c)
