The effect of Helicobacter pylori eradication on gastro-oesophageal reflux.
Tefera S, Hatlebakk JG, Berstad A. Tefera S, et al. Aliment Pharmacol Ther. 1999 Jul;13(7):915-20. doi: 10.1046/j.1365-2036.1999.00544.x. Aliment Pharmacol Ther. 1999. PMID: 10383526
Indications of 'atopic bowel' in patients with self-reported food hypersensitivity.
Lillestøl K, Helgeland L, Arslan Lied G, Florvaag E, Valeur J, Lind R, Berstad A. Lillestøl K, et al. Aliment Pharmacol Ther. 2010 May;31(10):1112-22. doi: 10.1111/j.1365-2036.2010.04261.x. Epub 2010 Feb 16. Aliment Pharmacol Ther. 2010. PMID: 20163379
CONCLUSIONS: Patients with self-reported food hypersensitivity had a high prevalence of IBS and atopic disease. Atopic patients had increased intestinal permeability and density of IgE-bearing cells compared with non-atopic patients, but gastrointestinal symptoms did not d …

Intestinal B cell-activating factor: an indicator of non-IgE-mediated hypersensitivity reactions to food?
Lied GA, Lillestøl K, Valeur J, Berstad A. Lied GA, et al. Aliment Pharmacol Ther. 2010 Jul;32(1):66-73. doi: 10.1111/j.1365-2036.2010.04314.x. Epub 2010 Mar 26. Aliment Pharmacol Ther. 2010. PMID: 20353497
CONCLUSIONS: The results suggest that BAFF might be a new mediating mechanism in food hypersensitivity reactions. Significantly higher levels in non-atopic compared with atopic patients, and no correlation between BAFF and IgE, suggest that BAFF might be involved particula …

Assessment of optimal atmospheric conditions for growth of Helicobacter pylori.
Henriksen TH, Lia A, Schøyen R, Thoresen T, Berstad A. Henriksen TH, et al. Eur J Clin Microbiol Infect Dis. 2000 Sep;19(9):718-20. doi: 10.1007/s100960000340. Eur J Clin Microbiol Infect Dis. 2000. PMID: 11057509
The number and diameter of colonies of Helicobacter pylori isolates growing on agar plates were determined to compare five methods that produce a culture atmosphere. ...Growth was significantly improved when the atmosphere outside the plastic incubation jars was enriched w …

Eradication of Helicobacter pylori does not increase acid reflux in patients with mild to moderate reflux oesophagitis.
Tefera S, Hatlebakk JG, Berstad AE, Berstad A. Tefera S, et al. Scand J Gastroenterol. 2002 Aug;37(8):877-83. doi: 10.1080/003655202760230810. Scand J Gastroenterol. 2002. PMID: 12229960

RESULTS: Fifteen months after eradication of H. pylori there was a significant decrease in percentage time oesophageal pH < 4 in the recumbent position only (P = 0.04). Despite a marked reduction in the severity of gastritis, there was no significant change in ga

They filled out a lifestyle questionnaire before the start of anti-Helicobacter therapy and again 1 year later. RESULTS: The prevalence of food intolerance decreased from 71% to 44% among patients with PUD (P < 0.0001) and from 76% to 63% among patients with G/D (P = 0.

On a molar basis, CBS gave a 17.4-fold greater absorption of bismuth compared to BSN. CONCLUSIONS: The presence of an active ulcer does not significantly influence the absorption of bismuth from CBS or BSN....
