An increased skin microvessel density is associated with neurovascular complications in type 1 diabetes mellitus.

The aim of this study was to assess the blood vessel density and maturity in the skin of adults with type 1 diabetes in relation to the presence of late neurovascular complications. We included 148 patients (87 men) with a median (interquartile range) age of 41 (31-49) and median diabetes duration of 21 (17-30) years. Microvessel (CD133, CD34, CD31 and von Willebrand factor) markers were evaluated by indirect immunohistochemistry assay in material from a skin biopsy.

Dermal microvessel density and maturity is closely associated with atherogenic dyslipidemia and accumulation of advanced glycation end products in adult patients with type 1 diabetes.

In patients with diabetes, functional changes in microcirculation and subclinical vascular pathology precede clinical manifestation of microangiopathic complications. The objective of this study was to evaluate the association between established vascular risk factors and density, maturity, and reactivity of dermal blood vessels in adults with type 1 diabetes (DM1). We included 148 DM1 patients (87 men) with a median (IQR) age of 40.

Evaluation of sudomotor function in adult patients with long‑lasting type 1 diabetes.

INTRODUCTION The function of the sweat glands appears to be impaired in patients with diabetic complications. OBJECTIVES The aim of the study was to evaluate sudomotor function in adult patients with type 1 diabetes (DM1) and healthy controls and its relationship with metabolic control and diabetic complications. PATIENTS AND METHODS The study group included 404 patients with DM1 (194 women), aged 41 years (interquartile range [IQR], 32-51 years) and with disease duration of 23 years (IQR, 18-31 years).

Association between small fiber neuropathy and higher skin accumulation of advanced glycation end products in patients with type 1 diabetes.

INTRODUCTION Advanced glycation end products (AGEs) play a crucial role in the pathogenesis of diabetic peripheral neuropathy (DPN). OBJECTIVES The aim of the study was to assess the skin accumulation of AGEs in patients with long‑lasting type 1 diabetes in relation to the presence of DPN. PATIENTS AND METHODS We evaluated 178 patients with type 1 diabetes (99 men; age, 43 years [interquartile range [IQR], 34-54 years]; disease duration, 25 years [IQR, 18-31 years]).
