Background
IL-10 is a major anti-inflammatory cytokine that prevents inflammation-mediated tissue damage. We characterized the production of IL-10 by sinonasal tissue cells following exposure to Staphylococcus aureus enterotoxin B (SEB), which elicits cellular responses and is associated with the pathogenesis of eosinophilic chronic rhinosinusitis (ECRS).Methods
Dispersed nasal polyp (NP) cells and uncinate tissue (UT) cells were prepared from patients with CRS with and without NP, respectively. Cells were incubated with SEB, and then the levels of IL-10 in the cell supernatants were determined. The effect of neutralizing IL-10 on SEB-induced IL-5, IL-13, IFN-γ, and IL-17A production was examined. Expression of IL-10 in NPs was also determined.Results
IL-10 was expressed in infiltrating inflammatory cells in NPs. NP cells, especially non-adherent NP cells, produced substantial amounts of IL-10 in response to SEB. Although baseline production of IL-10 was significantly higher in NP cells than UT cells, the degree of IL-10 response to SEB was not significantly different between the cell types. The degree of IL-10 production was negatively correlated with the degree of eosinophilia both in tissues and peripheral blood whereas positively correlated with the 1-s forced expiratory volume/forced vital capacity ratio. Patients with severe ECRS displayed a significant decrease in IL-10 production compared with those with non-ECRS. IL-10 neutralization significantly augmented SEB-induced IL-13 and IFN-γ production by NP cells.Conclusions
Impaired IL-10 production in response to SEB in NP may exacerbate the pathophysiology of ECRS including eosinophilia and lower airway obstruction. 相似文献52.

AIMS: A multicentric observational study was performed to update the available information on reflux oesophagitis in Italy. METHODS: In phase I, the number and severity of reflux oesophagitis diagnosed in 1 year (2003) were reported together with the associated endoscopic findings. In phase II, oesophagitis patients consecutively referred in a 3-month period were analysed. A multivariate analysis was used to identify the risk factors for severe oesophagitis. RESULTS: 253,992 upper endoscopies were collected. The overall prevalence of oesophagitis was 14.8% and the endoscopic findings associated with oesophagitis were hiatus hernia (46.3%), duodenal ulcer (10.7%), gastric ulcer (3.6%) and Barrett's oesophagus (2.9%). In phase II, 1542 reflux oesophagitis patients were analysed (60.3% males; mean age 50.7 +/-16.6 years). Only 53.4% of patients reported heartburn and/or regurgitation as main complaint. Severe symptoms, age > 50 years, hiatus hernia and male gender were identified as independent predictors of severe oesophagitis. CONCLUSIONS: Oesophagitis is the most frequent among the peptic diseases of the upper gastro-intestinal tract. Only half of the oesophagitis patients reported typical reflux symptoms as dominant. Advanced age, male gender, severe symptoms and hiatus hernia were independent risk factors for severe disease. 相似文献

Langerhans cell histiocytosis is a rare neoplastic proliferative disorder of the Langerhans cells. The clinical course is variable, ranging from a low symptomatic single bone lesion to fatal multiple organ involvement. Rarely, the sternum can be the first and single location of the disease. We report on a 12‐year‐old boy who presented with an aggressive lytic lesion of the proximal sternum associated with local pain and afternoon fever. Histopathological analysis of the closed biopsy specimen indicated eosinophilic granuloma of bone/Langerhans cell histiocytosis. Soon after the biopsy procedure the pain and fever subsided. Computed tomography at 2 months showed healing of the lytic lesion. The patient received no other type of treatment. At 2 year follow up he was symptom and disease free. 相似文献

Relationship between severity and symptoms of reflux oesophagitis in elderly patients in Japan 总被引:6,自引:0,他引:6

Since information concerning reflux oesophagitis in the elderly is limited, particularly in Japan, the severity and symptomatic profiles of reflux oesophagitis in elderly patients were investigated. One hundred and nineteen patients with reflux oesophagitis found among 2278 endoscopy cases between 1993 and 1996 were investigated in this study. The patients were divided into two groups, elderly and non-elderly. The severity of reflux oesophagitis was estimated by the Los Angeles classification. The presence or absence of typical symptoms (heartburn and regurgitation) was determined by interview. Reflux oesophagitis was not only more frequently found in the elderly group, but was more severe than in the non-elderly. Although the degree of manifestation of typical symptoms was similar between the elderly and the non-elderly with high-grade oesophagitis, the elderly patients with mild reflux oesophagitis were less symptomatic than the non-elderly. Mild reflux oesophagitis in the elderly may be missed due to its rarity of typical reflux symptoms and a substantial number of elderly persons might have subclinical reflux oesophagitis. 相似文献

Eosinophilic granulomatosis with polyangiitis (EGPA) is often associated with peripheral neuropathy, but reports of central nervous system involvement are quite rare. We herein report a patient with EGPA first identified as having hypereosinophilia who later developed asthma, eosinophilic otitis media, sinusitis, and hemorrhagic colitis. She subsequently developed hemiparesis. Head magnetic resonance imaging revealed multiple cerebral infarctions with subcortical and subarachnoid hemorrhaging colocalized at the bilateral border zone areas. She was diagnosed with EGPA-induced stroke and successfully treated with oral prednisolone. Inflammation in the small cerebral arteries in EGPA may induce bilateral border zone infarction with colocalizing subcortical and subarachnoid hemorrhaging. 相似文献
