[Primary eosinophilic colitis in a celiac patient].

Primary eosinophilic gastrointestinal disorders include a spectrum of inflammatory chronic diseases in which eosinophils infiltrate the gut in the absence of known causes of such tissue eosinophilia. They may affect any area of the gastrointestinal tract although exclusive colonic disease is exceptional. Due to their low prevalence these disorders are not usually taken into account when making a differential diagnosis in a patient with chronic diarrhea, which is the reason why in many cases the diagnosis can take many years.

[10-day triple therapy with esomeprazole 40 mg/12 h vs. quadruple concomitant non-bismuth therapy as first line treatment for Helicobacter pylori infection].

Introduction: Quadruple concomitant non-bismuth therapy has recently become the most widely prescribed first-line treatment for Helicobacter pylori infection in Spain. Whether optimized conventional triple therapy can achieve comparable efficacy rates remains to be seen.

Material And Methods: Retrospective study comparing the efficacy of triple and quadruple concomitant therapy, and sub-analysis following administration of both for 10 days with esomeprazole 40mg/12h.

[Cuadruple concomitant non-bismuth therapy vs. classical triple therapy as first line therapy for Helicobacter pylori infection].
