Overweight is a risk factor for both erosive and non-erosive reflux disease
Studies have reported that the association between overweight and erosive oesophagitis is very strong, whilst seeming less consistent with non-erosive reflux disease. We have hypothesized that this difference may be due to the heterogeneity of endoscopy-negative population. We studied 81 patients with erosive oesophagitis, 48 controls and 295 endoscopy-negative patients classified by impedance-pH-testing as: (1) pH-POS (abnormal acid exposure); (2) hypersensitive oesophagus (normal acid exposure/SAP+); (3) functional heartburn (normal acid exposure/SAP-). Body mass index was also calculated. Mean body mass index was significantly higher (p<0.05) in erosive oesophagitis than in endoscopy-negative patients as a whole and controls [27 (18-40) vs. 25 (16-48) vs. 23 (16-34)]. However, the separation of endoscopy-negative patients showed that mean body mass index was higher (p<0.05) in those with increased acid exposure time [26 (18-45)] than in hypersensitive oesophagus [24 (16-48)]. The former subgroup was similar to erosive oesophagitis, whilst the latter one to both functional heartburn [23 (16-34)] and controls (p=ns). Increased body mass index represented a risk factor for erosive oesophagitis (odds ratio 1.4; 95% confidence in...Continue Reading

Allergy and Asthma
Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
