There have seen several studies evaluating the efficacy of anti-tumor necrosis factor (anti-TNF) compared with conventional therapy (i.e. immunomodulators, mesalamine, or placebo) at preventing postoperative Crohn's disease (CD) recurrence. The results of these studies have been variable and the magnitude by which anti-TNF therapy alters the natural history of CD in the postoperative setting has not yet been fully defined.", 'A comprehensive search of PubMed/MEDLINE, Scopus, CINAHL, and Cochrane databases was performed (May 2014). All studies on adult patients with CD that compared anti-TNF therapy versus conventional therapy or placebo to prevent CD recurrence were included. Meta-analysis was performed using the Mantel-Haenszel (fixed effects) model with odds ratio (OR) to assess for clinical remission.', 'In the pooled analysis, there was a higher frequency of achieving clinical remission beyond 1 year from time of surgery among patients receiving anti-TNF therapy compared with conventional therapy [OR 6.41; 95% confidence interval (CI) 2.88-14.27]. There was also a significantly higher rate of achieving both endoscopic (OR 26.44; 95% CI 10.48-66.68) and histologic remission (OR 9.80; 95% CI 2.54-37.81) in the anti-TNF therapy group compared with the conventional therapy group.

This study examined the contribution of airway inflammation to the delayed lung function recovery that occurs in some people following virus-induced asthma exacerbations.', 'Subjects (n = 40) were recruited at hospital admission for acute asthma exacerbation. Respiratory virus infection was diagnosed by viral nucleic acid detection and/or cell culture, using induced sputum, nasal, or throat swabs. Data collected included lung function, answers to common cold and asthma control questionnaires, and induced sputum cellular profiles. Subjects were reexamined 4 to 6 weeks postexacerbation and were compared with stable asthmatic subjects (n = 26) who had been recruited from ambulatory care clinics.', 'Persistent airway obstruction, defined as lung function improvement at follow-up (ie, change in FEV1 percent predicted [Delta%FEV1]) of <15%, was observed in 10 subjects (25%). Airway recovery (Delta%FEV1, > or = 15%) was observed in the remaining subjects (30 subjects; 75%). During the acute episode, the airway-recovery group had increased total cell count (p = 0.019), increased number of neutrophils (p = 0.005), and increased percentage of neutrophils (p = 0.0043) compared to the group of stable subjects with asthma. Postexacerbation, the airway-recovery group had reduced numbers of neutrophils and an increased percentage of eosinophils. In contrast, during exacerbation, subjects with persistent airway obstruction showed no differences in inflammatory cell counts compared to stable subjects with asthma, nor did cell counts change postexacerbation. Symptoms improved in both groups postexacerbation. However, in the persistent-airway-obstruction group, asthma remained uncontrolled.

Coagulation Factor XIII (FXIII) plays an important role in wound healing by stabilizing fibrin clots and cross-linking extracellular matrix proteins. FXIII is expressed in cells of the monocyte/macrophage and dendritic cell lineages in response to type 2 cytokines.', 'We sought to determine the association between FXIII and asthma pathobiology.', 'We analyzed the expression of FXIII mRNA and protein levels in bronchoalveolar lavage samples obtained before and after segmental allergen challenge from patients with mild asthma and in induced sputum samples collected from patients with mild-to-moderate and severe asthma.', 'FXIII mRNA and protein levels were highly upregulated in bronchoalveolar cells and fluid after allergen challenge and mRNA levels correlated with protein levels. In sputum of asthmatic patients, FXIII expression was positively correlated with type 2 immune response and dendritic cell markers (CD209 and CD207). FXIII expression was also associated with increased airflow limitation (FEV1/forced vital capacity and residual volume/total lung capacity ratios) and greater reversibility to -agonists.
