Helicobacter pylori infection is associated with increased accumulation of advanced glycation end products in the skin in patients with type 1 diabetes: A preliminary study.

Abstract

Helicobacter pylori infection (HPI) is more frequently diagnosed in patients with diabetes. Insulin resistance in patients with type 1 diabetes (DMT1) is associated with the accumulation of advanced glycation end products (AGEs) in the skin and progression of chronic complications. Assessment of the relationship between the incidence of HPI and skin AGEs in patients with DMT1. The study included 103 Caucasian patients with a DMT1 duration >5 years. A fast qualitative test was performed to detect the HP antigen in fecal samples (Hedrex). The content of AGEs in the skin was estimated using an AGE Reader device (DiagnOptics). The HP-positive (n = 31) and HP-negative (n = 72) groups did not differ in terms of age, gender, duration of diabetes, fat content, body mass index (BMI) and lipid profile, metabolic control, and inflammatory response markers. The studied groups differed in the amount of AGEs in the skin. The relationship between HPI and increased AGEs in the skin was confirmed in a multifactor regression model taking into account age, gender, DMT1 duration, glycated hemoglobin A1c (HbA1c), BMI, low-density lipoprotein cholesterol (LDL-C) and the presence of hypertension, and tobacco use. The studied groups also differed in serum levels of vitamin D. Increased accumulation of AGEs in the skin of patients with DMT1 with coexisting HPI suggests that eradication of HP may significantly improve DMT1 outcomes.
