RESUMEN
INTRODUCTION: Chronic urticaria is thought to have numerous causative factors including a large variety of infectious conditions, food intake, and drugs. The impact of Helicobacter pylori infection has been studied with ambiguous results. The aim of this study was to investigate the course of chronic urticaria in H. pylori-positive patients undergoing eradication compared to H. pylori-negative urticaria patients. PATIENTS AND METHODS: We included 74 urticaria patients with positive H. pylori breath test and 74 age- and sex-matched H. pylori-negative controls. All urticaria patients underwent an extensive diagnostic work-up to search for trigger foci. H. pylori-infected patients were submitted to eradication therapy. Mean follow-up time was 58 months. RESULTS: Neither the prevalence of H. pylori nor the eradication therapy had an influence on the clinical course of chronic urticaria. In 81.1% of H. pylori-infected patients at least one additional infectious focus was found. Nevertheless, it could be shown that individuals that described any kind of symptom relief presented with higher serum IgE levels at diagnosis (198.1 vs 115.7 kU/L, p= .027) but this effect was independent of H. pylori infection. CONCLUSIONS: In conclusion there is no evidence that eradication of H. pylori improves the outcome in patients with chronic urticaria. The high rate of spontaneous remission and the coexistence of multiple foci will always obscure the evaluation of any specific antimicrobial therapy.

Helicobacter pylori infection leads to a broad spectrum of disease manifestations such as gastritis, ulcer disease, and even gastric carcinoma. The genetically determined immune response and subsequent inflammation influence the degree of mucosal damage. Adhesion molecules of the CD11 cluster play an important role in adherence of neutrophils to endothelial cells in inflammation. We conducted a haplotype-based analysis of the CD11 cluster in a sample of 315 patients with H. pylori infection and investigated associations with gastric erosions and ulcer disease. Twelve single nucleotide polymorphisms (SNPs) covering the genes CD11a, CD11b, and CD11c were genotyped by Taqman technology. Linkage disequilibrium (LD) was assessed within the CD11 cluster and haplotype case-control analysis was conducted. Sliding window haplotype analysis identified a haplotype consisting of the markers CD11c exon 15 and intron 31 associated with gastric ulcer disease. Patients carrying the haplotype GA bear a 2.4-fold increased risk. No significant associations of single markers with disease outcome were found. High-density LD mapping and mutation detection of CD11c in larger samples will be necessary to confirm our findings and identify the causative variant. Thus, we conclude that genetic variants in the CD11 cluster may play a role in the development of gastric ulcer in chronic H. pylori infection presumably by influencing leukocyte adhesion. The biological effect of genetic variants of CD11c in gastric inflammation needs further clarification.

A 45-year-old woman was admitted to our hospital complaining of upper abdominal pain. Seven months earlier a laparoscopic cholecystectomy had been carried out and a solitary gallstone removed together with the gallbladder. The patient now suffered from pain of the same character but lower intensity compared to the situation before the operation. At admission there were no abnormal laboratory findings, especially no signs of infection or cholestasis. Ultrasound revealed a stone in a gallbladder-like structure in the right epigastric region. ERCP revealed an inconspicuous cystic duct stump and no pathological findings in the extra- and intrahepatic bile ducts. MRCP and CT showed a cyst-like structure in the gallbladder region containing a concrement. The patient was transferred to the Department of Surgery for exploratory laparotomy, and a residual gallbladder with an infundibular gallstone was removed. The recurrent upper abdominal pain was obviously caused by a gallstone redeveloped after incomplete laparoscopic gallbladder resection. Retrospectively it could not be discerned whether a doubled or a septated gallbladder was the reason for the initial incomplete resection.

We here report the successful but unusual course of colonic tattooing in a patient with a carcinoma in situ in a polyp. A 70-year-old woman was admitted for persistent diarrhea, occult fecal blood, and anemia. During colonoscopy, a pedunculated large polyp in the sigmoid colon occluding the lumen was removed successfully. Histopathological examination revealed a carcinoma in situ with a resection of the peduncle in sano. At the second sigmoidoscopy, the polypectomy site was marked with India ink to facilitate the recovery of the polypectomy site in follow-up endoscopies. Three months later, the India ink had spread in the submucosal layer and a segment measuring 15 cm was colored dark blue. At the original polypectomy site, an uncolored flat mucosal proliferation was found above the dark colonic wall. After mucosectomy, the tissue was classified as hyperplastic. Six weeks later, a second control sigmoidoscopy did not show any suspicious mucosal alterations.

Intestinal endometriosis is the most frequent extragenital manifestation of this disease. Sometimes patients even present with acute bowel obstruction. We report on a 46-year-old woman complaining about recurrent sanguineous and mucous diarrhea and spasms for several years. Colonoscopy showed a stenosis in the sigmoid colon without macroscopically visible alterations of the mucosa. Computertomography, ultrasound and barium contrast enema did not provide us with further information about the origin of the stenosis. Biopsies out of the mucosa at the stenosis showed typical endometriosis tissue. After starting a conservative therapy with GnRH-agonist gosereline the patient became completely free of symptoms. The coincidence of endometriosis and M. Crohn has to be taken into consideration. Therapy planning should include a close co-operation with gynaecologists and surgeons to transfer the patient to surgical intervention when needed.
