A 45-year-old-male who had underlying ulcerative colitis and presented with fever and dry cough. Initially, the patient was considered to have invasive aspergillosis due to a positive galactomannan assay. He was treated with amphotericin B followed by voriconazole. Nevertheless, the patient deteriorated clinically and radiographically. The lung biopsy revealed eosinophilic pneumonia, and ELISA for Toxocara antigen was positive, leading to a diagnosis of pulmonary toxocariasis. After a 10-day treatment course with albendazole and adjunctive steroids, the patient recovered completely without any sequelae. Pulmonary toxocariasis may be considered in patients with subacute or chronic pneumonia unresponsive to antibiotic agents, particularly in cases with eosinophilia.  相似文献

目的:探讨参苓白术辅助治疗对老年溃疡性结肠炎伴脓血便患者临床疗效及免疫功能的影响。方法:选取于我院进行治疗的老年溃疡性结肠炎伴脓血便患者50例,随机分为实验组与对照组,每组25例。对照组患者给予柳氮磺吡啶结肠溶胶囊进行治疗,实验组患者在对照组的基础上联合使用参苓白术丸进行治疗,两组患者均治疗3个月,比较两组患者治疗前后血清白介素-2(IL-2)、γ-干扰素(IFN-γ)及白介素-10(IL-10)水平,并评价两组患者的临床疗效。结果:与治疗前相比,两组患者治疗后的血清IL-2、IFN-γ水平均显著降低,IL-10明显升高;与对照组相比,实验组患者血清IL-2、IFN-γ水平较低,IL-10水平更高(P0.05);且与对照组相比,实验组患者的临床总有效率较高(P0.05)。结论:参苓白术散能有效改善老年溃疡性结肠炎伴脓血便患者的免疫功能并提高其临床疗效。  相似文献

The gut microbiota plays an important yet incompletely understood role in the induction and propagation of ulcerative colitis (UC). Organism-level efforts to identify UC-associated microbes have revealed the importance of community structure, but less is known about the molecular effectors of disease. We performed 16S rRNA gene sequencing in parallel with label-free data-dependent LC-MS/MS proteomics to characterize the stool microbiomes of healthy (n = 8) and UC (n = 10) patients. Comparisons of taxonomic composition between techniques revealed major differences in community structure partially attributable to the additional detection of host, fungal, viral, and food peptides by metaproteomics. Differential expression analysis of metaproteomic data identified 176 significantly enriched protein groups between healthy and UC patients. Gene ontology analysis revealed several enriched functions with serine-type endopeptidase activity overrepresented in UC patients. Using a biotinylated fluorophosphonate probe and streptavidin-based enrichment, we show that serine endopeptidases are active in patient fecal samples and that additional putative serine hydrolases are detectable by this approach compared with unenriched profiling. Finally, as metaproteomic databases expand, they are expected to asymptotically approach completeness. Using ComPIL and de novo peptide sequencing, we estimate the size of the probable peptide space unidentified (“dark peptidome”) by our large database approach to establish a rough benchmark for database sufficiency. Despite high variability inherent in patient samples, our analysis yielded a catalog of differentially enriched proteins between healthy and UC fecal proteomes. This catalog provides a clinically relevant jumping-off point for further molecular-level studies aimed at identifying the microbial underpinnings of UC.  相似文献

The effect of lactoperoxidase (LPO) on dextran sulfate sodium-induced colitis was examined in mice. After 9 d of colitis induction, weight loss, colon shortening, and the histological score were significantly suppressed in mice orally administered LPO (62.5 mg/body/d) as compared to a group administered bovine serum albumin. These results suggest that LPO exhibits anti-inflammatory effects in the gastrointestinal tract.  相似文献

溃疡性结肠炎对凝血-纤溶系统激活现象的探讨   总被引:1,自引:0,他引:1  
目的:通过对活动期和缓解期溃疡性结肠炎(UC)患者凝血和纤溶系统各指标的检测和对比,探讨肠炎对凝血-纤溶系统的激活作用。方法:以20名缓解期溃疡性结肠炎患者为对照,检测20名活动期溃疡性结肠炎患者体内凝血和纤溶系统各指标,包括血小板计数、活化部分凝血活酶时间(APTT)、凝血酶时间(TT)、凝血酶原时间(PT)、凝血因子Ⅻ、Ⅺ、Ⅹ、Ⅸ、Ⅷ、Ⅶ、Ⅴ、Ⅱ,纤维蛋白原和D二聚体(D-D)。结果:活动期溃疡性结肠炎患者体内凝血因子Ⅺ、Ⅹ、Ⅸ、Ⅷ、Ⅴ、Ⅱ因子以及血浆纤维蛋白原、D-二聚体水平显著高于非活动期患者,其他指标没有显著差别。结论:活动期溃疡性结肠炎患者凝血-纤溶系统处于激活状态,提示肠炎可以激活凝血-纤溶系统。  相似文献

研究发光二极管(1ight-emittingdiode,Um)直肠内照射对大鼠实验性溃疡性结肠炎(ulcerative colitis,UC)的抗过氧化损伤以及促进结肠粘膜组织的修复作用。34只大鼠随机分成3组:正常对照组10只、病理模型组12只与病理模型+LED照射治疗组12只.研究中采用乙酸局部刺激复制大鼠UC模型,其中LED治疗组应用LED结肠内照射,1日1次,共10d。其后观察各组的病理变化,血清过氧化损伤水平。结果显示,LED结肠内照射能够促使实验性溃疡性结肠炎的组织修复;显著降低溃疡性结肠炎大鼠血清MDA水平、升高SOD活性。实验表明LED结肠内照射实验性溃疡性结肠炎大鼠具有抗过氧化损伤作用以及促进结肠粘膜组织的修复作用。  相似文献

A variety of epidemiologic studies have focused on the association between macrophage migration inhibitory factor (MIF) gene − 173G/C polymorphism and inflammatory bowel disease (IBD). However, results in different studies have been inconsistent. In order to derive a more precise estimation of the associations, we performed this meta-analysis and systematic searches of electronic databases PubMed and Web of Science (up to April 30, 2013). Based on our search criteria, a total of seven eligible studies concerning the MIF − 173G/C polymorphism and IBD risk were included in the final meta-analysis, comprising 2162 IBD cases and 2134 controls. Significant association was found between MIF − 173G/C polymorphism and the risk of IBD when all studies were pooled into the meta-analysis (for C allele vs. G allele: OR = 1.25, 95% CI = 1.12–1.41, p = 0.000; for C/C vs. G/G: OR = 1.71, 95% CI = 1.23–2.39, p = 0.002; for C/C + G/C vs. G/G: OR = 1.24, 95% CI = 1.09–1.42, p = 0.002; for C/C vs. G/C + G/G: OR = 1.67, 95% CI = 1.20–2.33, p = 0.002). Heterogeneity and publication bias did not exist in the overall comparisons. The present meta-analysis suggests an association between the MIF − 173G/C polymorphism and IBD risk. However, due to few studies and the selection bias existed in some studies, the results should be interpreted with caution.  相似文献
