Presence of pre-diabetes in Helicobacter pylori positive versus Helicobacter pylori negative patients having dyspepsia.

Pre-diabetes is a state of intermediate hyperglycaemia. Helicobacter (H) pylori infection is an established risk factor for pre-diabetes. This comparative cross-sectional study was done in Mayo Hospital Lahore from November 2015 to August 2016 in which 270 patients underwent upper gastrointestinal endoscopy with antral biopsy. An oral glucose tolerance test was done half to one hour after endoscopy. Patients were diagnosed having pre-diabetes according to American Diabetic Association criteria. Cases were divided into Group A and B based on the presence or absence of histopathological evidence of H. pylori respectively. Comparison was done to see the occurrence of pre-diabetes in H. pylori positive versus helicobacter negative dyspeptic patients. Results showed that 79 (58.52%) in Group-A and 62 (45.93%) in Group-B had pre-diabetes while remaining 56 (41.48%) in Group-A and 73 (54.07%) in Group-B had no findings of this morbidity, p value was calculated as 0.03 showing a significant difference. It was concluded that H. pylori infection is significantly associated with pre-diabetes.
