“…Some studies have shown a higher prevalence of H.pylori infection in people with type 1 (de Luis et al, 1998; El-Eshmawy et al, 2011) and type 2 diabetes (Bener et al, 2007;Devrajani et al, 2010). This relationship seems to be correlated with gender (Hamed et al, 2008), BMI (Bener et al, 2007;Perdichizzi et al, 1996), the duration of diabetes (de Luis et al, 1998), the presence of dyspepsia, cardiovascular autonomic neuropathy (Gulcelik et al, 2005) and glycated hemoglobin (Chen and Blaser, 2012;Hsieh et al, 2013), whilst other studies have indicated neutral or even negative results (Anastasios et al, 2002;Demir et al, 2008;Gillum, 2004).…”
