BACKGROUND Intraductal papillary neoplasm of the bile duct(IPNB) is pathologically similar to intraductal papillary mucinous neoplasm(IPMN). However, there are several significant differences between them. The rate of IPMN associated with extrapancreatic malignancies has been reported to range from 10%-40%, and it may occasionally be complicated with the presence of fistulas. IPMN associated with malignant IPNB is extremely rare and only nine cases have been reported in the literature.CASE SUMMARY We report a 52-year-old man who presented with recurrent cholangitis for nine months. Computed tomography and magnetic resonance cholangiopancreatography showed the common bile duct stricture with dilated pancreatobiliary duct without other abnormal findings. The underlying pathogenesis could not be identified based on the radiologic images. Endoscopic retrograde cholangiopancreatography revealed a pancreatobiliary fistula with dilated main pancreatic duct, biliary stricture with dilated biliary tree, and mucus discharge from the enlarged orifice of the major papilla. The patient underwent SpyGlass cholangiopancreatoscopy due to a suspected mucin-producing biliary neoplasm and indeterminate main pancreatic duct dilatation. Multiple papillary growing neoplasms with vascular images, with the extent of lesions spreading in the biliopancreatic ductal lumens, were identified by SpyGlass. In addition, the presence of a pancreatobiliary fistula was also identified. The patient was diagnosed as having benign IPMN and malignant IPNB with focal invasion by postoperative pathology. Furthermore, varying histological subtypes were present in both IPMN and IPNB. Pylorus-preserving pancreaticoduodenectomy was performed on the patient with excellent results during the 52 month followup period.CONCLUSION We deemed that pancreatography and SpyGlass allowed for an efficient diagnosis of IPMN with pancreatobiliary fistula, whereas the etiology could not be identified by radiologic imaging. 相似文献

BACKGROUND Polyomavirus-associated nephropathy is a leading cause of kidney allograft failure. Therapeutic options are limited and prompt reduction of the net state of immunosuppression represents the mainstay of treatment. More recent application of aggressive screening and management protocols for BK-virus infection after renal transplantation has shown encouraging results. Nevertheless,long-term outcome for patients with BK-viremia and nephropathy remains obscure. Risk factors for BK-virus infection are also unclear.AIM To investigate incidence, risk factors, and outcome of BK-virus infection after kidney transplantation.METHODS This single-centre observational study with a median follow up of 57(31-80) mo comprises 629 consecutive adult patients who underwent kidney transplantation between 2007 and 2013. Data were prospectively recorded and annually reviewed until 2016. Recipients were periodically screened for BK-virus by plasmaquantitative polymerized chain reaction. Patients with BK viral load ≥ 1000 copies/mL were diagnosed BK-viremia and underwent histological assessment to rule out nephropathy. In case of BK-viremia, immunosuppression was minimized according to a prespecified protocol. The following outcomes were evaluated: patient survival, overall graft survival, graft failure considering death as a competing risk, 30-d-event-censored graft failure, response to treatment,rejection, renal function, urologic complications, opportunistic infections, newonset diabetes after transplantation, and malignancies. We used a multivariable model to analyse risk factors for BK-viremia and nephropathy.RESULTS BK-viremia was detected in 9.5% recipients. Initial viral load was high(≥ 10000 copies/mL) in 66.7% and low(< 10000 copies/mL) in 33.3% of these patients.Polyomavirus-associated nephropathy was diagnosed in 6.5% of the study population. Patients with high initial viral load were more likely to experience sustained viremia(95% vs 25%, P < 0.00001), nephropathy(92.5% vs 15%, P <0.00001), and polyomavirus-related graft loss(27.5% vs 0%, P = 0.0108) than recipients with low initial viral load. Comparison between recipients with or without BK-viremia showed that the proportion of patients with Afro-Caribbean ethnicity(33.3% vs 16.5%, P = 0.0024), panel-reactive antibody ≥ 50%(30% vs14.6%, P = 0.0047), human leukocyte antigen(HLA) mismatching > 4(26.7% vs13.4%, P = 0.0110), and rejection within thirty days of transplant(21.7% vs 9.5%; P= 0.0073) was higher in the viremic group. Five-year patient and overall graft survival rates for patients with or without BK-viremia were similar. However,viremic recipients showed higher 5-year crude cumulative(22.5% vs 12.2%, P =0.0270) and 30-d-event-censored(22.5% vs 7.1%, P = 0.001) incidences of graft failure than control. In the viremic group we also observed higher proportions of recipients with 5-year estimated glomerular filtration rate < 30 mL/min than the group without viremia: 45% vs 27%(P = 0.0064). Urologic complications were comparable between the two groups. Response to treatment was complete in55%, partial in 26.7%, and absent in 18.3% patients. The nephropathy group showed higher 5-year crude cumulative and 30-d-event-censored incidences of graft failure than control: 29.1% vs 12.1%(P = 0.008) and 29.1% vs 7.2%(P <0.001), respectively. Our multivariable model demonstrated that Afro-Caribbean ethnicity, panel-reactive antibody > 50%, HLA mismatching > 4, and rejection were independent risk factors for BK-virus viremia whereas cytomegalovirus prophylaxis was protective.CONCLUSION Current treatment of BK-virus infection offers sub-optimal results. Initial viremia is a valuable parameter to detect patients at increased risk of nephropathy. Panelreactive antibody > 50% and Afro-Caribbean ethnicity are independent predictors of BK-virus infection whereas cytomegalovirus prophylaxis has a protective effect. 相似文献

BACKGROUND Overexpression of heat shock proteins(HSPs) is associated with several malignancies and contributes to the development, progression, and metastasis of cancer, in addition to the inhibition of cellular death. In recent years, there has been active research into using HSP inhibitors in several malignancies. Due to the poor prognosis of esophageal adenocarcinoma(EAC), it would be valuable to find new biomarkers for the development of cancer treatments.AIM To evaluate the expressions of HSP27 and HSP70 and their effect on survival in EAC.METHODS Immunohistochemical analyses and evaluations of HSP27 and HSP70 expression were performed on all available samples from 93 patients diagnosed with EACbetween 1990 and 2007 at two university hospitals. Fifteen cases with Barrett's metaplasia and 5 control cases from the same patient population were included in the analysis. HSP expression was quantitatively assessed and classified as high or low. Kaplan-Meier analyses and Cox regression models adjusting for age and sex as well as tumor site, stage, and grade were used to evaluate the effect on survival.RESULTS Tumor stage and surgical treatment were the main prognostic factors. High HSP27 expression in cancer cases was a strong negative predictive factor, with a mean survival of 23 mo compared to the 49 mo in cases with a low expression(P= 0.018). The results were similar for HSP70, with a poorer survival of 17 mo in cases with high HSP70 expression, in contrast to 40 mo(P = 0.006) in cases with a low expression. A Cox regression survival analysis was performed, adjusting for possible confounding factors, and higher HSP27 and HSP70 expressions remained an independent negative prognostic factor. The HSPs' correlation with survival was not affected by cancer treatments. When the analysis was adjusted for all factors, the odds ratios for HSP27 and HSP70 were 3.3(CI: 1.6–6.6, P =0.001) and 2.2(CI: 1.2–3.9, P = 0.02), respectively.CONCLUSION HSP27 and HSP70 overexpression is associated with poor survival in EAC, which is, to the best of our knowledge, reported for the first time. 相似文献

BACKGROUND Cumulative evidence suggests that the aberrant immune responses in acquired aplastic anemia(AA) are sustained by active chronic infections in genetically susceptible individuals. Recently, the constant source to trigger and sustain the pathophysiology has been proposed to come from the altered gut microbiota and chronic intestinal inflammation. In this case, our serendipitous finding provides convincing evidence that the persistently dysregulated autoimmunity may be generated, at least in a significant proposition of AA patients, by the altered gut microbiota and compromised intestinal epithelium.CASE SUMMARY A 30-year-old Chinese male patient with refractory severe AA experienced a 3-month-long febrile episode, and his fever was refractory to many kinds of injected broad-spectrum antibiotics. When presenting with abdominal cramps, he was prescribed oral mannitol and gentamycin to get rid of the gut infection. This treatment resulted in a quick resolution of the fever. Unanticipatedly, it also produced an excellent hematological response. He had undergone three episodes of recurrence within the one-year treatment, with each recurrence occurring 7-8 wk from the gastrointestinal inflammation eliminating preparations. However,subsequent treatments were able to produce subsequent remissions and consecutive treatments were successful in achieving durative hematological improvements, strongly indicating an etiological association between chronic gut inflammation and the development of AA. Interestingly, comorbid diseases superimposed on this patient(namely, psychiatric disorders, hypertension,insulin resistance, and renal dysfunction) were ameliorated together with the hematological improvements.CONCLUSION Chronic gut inflammation may be responsible for AA pathogenesis. The comorbidities and AA may share a common etiological association. 相似文献

BACKGROUND Post-endoscopic retrograde cholangiopancreatography(ERCP)pancreatitis(PEP)is a critical and poorly managed complication of ERCP.Endoscopists need to understand the risk factors for PEP.However,the majority of studies investigating ERCP-related risk factors have included well-trained endoscopists,with the issue of endoscopist experience on PEP incidence not having been systematically evaluated.AIM To explore the risk factors for PEP in beginner endoscopists without supervision.METHODS We performed a retrospective analysis of 293 patients,with naïve papilla and no history of pancreatitis,treated using bile duct cannulation.Patients were classified according to the endoscopist’s experience(beginner vs expert).The angle of the distal common bile duct(CBD)was measured as the angle between the lower wall of the bile duct and a vertical line extending to the lower wall of the bile duct on coronal view computed tomography.RESULTS After propensity matching,there were no differences between patients treated by the expert and beginner endoscopist with regard to age,sex,mean bile duct dilatation,and ratio of benign disease.The distal CBD angle was classified as acute(>30º)or obtuse(≤30º),based on the mean angle of 29.9ºfor the group.An acute distal CBD angle was a significant risk factor for PEP for beginner(P=0.049),but not expert.CONCLUSION For beginner endoscopists first performing unsupervised ERCP,cases with an obtuse distal CBD angle may be more appropriate to lower the risk of PEP. 相似文献
