OBJECTIVE
Inflammatory bowel diseases (IBD) are associated with significant morbidity and economic burden. The variable course of IBD creates a need for predictors of clinical outcomes and health resource utilization (HRU) to guide treatment decisions. We aimed to identify clinical, serological or genetic markers associated with inpatient resource utilization in patients with ulcerative colitis (UC) and Crohn's disease (CD).METHODS
Patients with IBD with available genetic and serological data who had at least one emergency department visit or hospitalization in a 3‐year period were included. The primary outcome measure was HRU, as measured by the All Patient Refined Diagnosis Related Group classification system. Univariate and multivariate linear and logistic regression models were used to identify the associations with HRU.RESULTS
Altogether 858 (562 CD and 296 UC) patients were included. Anti‐CBir1 seropositivity (P = 0.002, effect size [ES]: 0.762, 95% confidence interval [CI] 0.512–1.012) and low socioeconomic status (P = 0.005, ES: 1.620 [95% CI 1.091–2.149]) were independently associated with a high HRU. CD diagnosis (P = 0.006, ES: –0.701 [95% CI –0.959 to –0.443]) was independently associated with a low inpatient HRU.CONCLUSION
In patients with IBD who required at least one emergency department visit or hospitalization, anti‐CBir1 antibody status may be a useful biomarker of HRU when formulating management strategies to reduce disease complications and resource utilization. 相似文献146.

This report describes an alternative technique to inoculate rabbits and to reproduce infection by Bovine herpesvirus 1 and 5. First, the nostrils are anaesthetized by aspersion with local anaesthetic. A few seconds later, and after proving the insensitivity of the zone, the rabbits are put on their back legs with their nostrils upwards and the inoculum is introduced slowly into each nostril by using disposable droppers. Clinical signs, viral isolation from nasal swabs, histological lesions found, positive polymerase chain reaction and antibodies production confirm the infection. This very simple and bloodless technique, where the animals are exposed to minor distress, may be useful for evaluating the virulence of BoHV-1 and BoHV-5 strains, to study the establishment of latent virus infection and to test the potential of experimental vaccines or properties of antiviral drugs. It may be also suitable for experimental infection with other respiratory viruses in this animal model. 相似文献

Molecular characterization of the 128-kDa immunodominant antigen of Helicobacter pylori associated with cytotoxicity and duodenal ulcer. 总被引:64,自引:0,他引:64 下载免费PDF全文
A Covacci S Censini M Bugnoli R Petracca D Burroni G Macchia A Massone E Papini Z Xiang N Figura et al. 《Proceedings of the National Academy of Sciences of the United States of America》1993,90(12):5791-5795
Helicobacter pylori has been associated with gastritis, peptic ulcer, and gastric adenocarcinoma. We report the nucleotide sequence and expression of an immunodominant antigen of H. pylori and the immune response to the antigen during disease. The antigen, named CagA (cytotoxin-associated gene A), is a hydrophilic, surface-exposed protein of 128 kDa produced by most clinical isolates. The size of the cagA gene and its protein varies in different strains by a mechanism that involves duplication of regions within the gene. Clinical isolates that do not produce the antigen do not have the gene and are unable to produce an active vacuolating cytotoxin. An ELISA to detect the immune response against a recombinant fragment of this protein detects 75.3% of patients with gastroduodenal diseases and 100% of patients with duodenal ulcer (P < 0.0005), suggesting that only bacteria harboring this protein are associated with disease. 相似文献
