Background: Patients with LADA are a clinically, immunologically, genetically heterogeneous group and the presence of thyroid autoimmunity (TA) appears to contribute to his heterogeneity. Aim:
Patients with TA had twice the risk of RD compared to patients without TA, odds ratios 2.27 (95% CI 0.8 la 5.7), p=0.004. %

The risk of NP was 1.8 times higher in patients with TA compared with patients without TA (95% CI 0.7 la 4.4; p=0.04). %

The aim was to evaluate the impact of thyroid autoimmunity on microangiopathic complications in LADA patients.

From 10 patients with DN, 4 of them (40%) had TA compared to 26 patients (27.7%) of 94 without DN. Patients with TA had the probability to develop this complication 1.7 times higher than those without TA, odds ratio 1.74 (95% CI 0.4 la 6.6, p=0.46). %

Material and method: LADA has been defined by the onset of diabetes at ages above 30 years, the lack of need for insulin therapy for at least 6 months after its first appearance, the presence of anti GAD antibodies (GADA). Positive titers of TPOAb (anti-thyroid peroxidase antibodies ) were observed in 30 (28.8%) out of 104 LADA patients. Prevalence of retinopathy (DR), peripheral neuropathy (PN), autonomic neuropathy (AN) and diabetic nephropathy (DN) were also evaluated.
With A N
Conclusions: Except diabetic nephropathy, the presence of thyroid autoimmunity in patients with LADA has determined a significantly higher prevalence of microangiopathic complications.

and aim
LADA is a form of autoimmune d i a b e t e s w i t h features overlapping type 1 and type 2 diabetes mellitus (type 2 DM) with slower decline of beta cell and insufficiently described. The aim of the study was to evaluate metabolic syndrome prevalence and components in LADA versus type 2 ts. diabetes pa
Material and method
Using a previously validated clinical screening tool, we selected 234 diabe pa ents. According to pancrea c ts into autoimmunity we assign pa two groups: 104 (57 female/47 male) LADA pa ts and 130 (68 female/62 ts. Clinical male) type 2 diabetes pa and laboratory data were obtained: weight, abdominal circumference, blood pressure, triglycerides, HDL-cholesterol. Presence of metabolic syndrome was evaluated according NCEP/ATP III criteria.

Results
Age at the onset of diabetes was 44.03±10.13 in LADA versus 49.7±9.7 in type 2 DM (p=0.002), and diabetes span was 6.5±4.15 vs 9.2±5.1 (p=0.001). In LADA group vs type 2 DM group we obtained following mean values: HDL cholesterol 47.78±14.34 vs 40.3±19.78 (p=0.001), triglycerides 168.25±113.10 vs 188.5±108.2 (p=0.024), systolic blood pressure 133.7±24.35 vs 141.44±20.67 (p=0.009). The prevalence of metabolic syndrome was 59.6% in LADA versus 88.4% in type 2 DM.
