1Late biliary complications in human alveolar echinococcosis are associated with high mortality显示文摘AIM:To evaluate the incidence of late biliary complications in non-resectable alveolar echinococcosis(AE)under long-term chemotherapy with benzimidazoles.METHODS:Retrospective analysis of AE patients with biliary complications occurring more than three years after the diagnosis of AE.We compared characteristics of patients with and without biliary complications,analyzed potential risk factor for biliary complications and performed survival analyses.RESULTS:Ninety four of 148 patients with AE in Zurich had non-resectable AE requiring long-term benzimidazole chemotherapy,of which 26(28%)patients developed late biliary complications.These patients had a median age of 55.5(35.5-65)years at diagnosis of AE and developed biliary complications after 15(8.25-19)years of chemotherapy.The most common biliary complications during long-term chemotherapy were late-onset cholangitis(n=14),sclerosing cholangitis-like lesions(n=8),hepatolithiasis(n=5),affection of the common bile duct(n=7)and secondary biliary cirrhosis(n=7).Thirteen of the 26 patients had undergone surgery(including 12 resections)before chemotherapy.Previous surgery was a risk factor for late biliary complications in linear regression analysis(P=0.012).CONCLUSION:Late biliary complications can be observed in nearly one third of patients with non-resectable AE,with previous surgery being a potential risk factor.After the occurrence of late biliary complications,the median survival is only 3 years,suggesting that late biliary complications indicate a poor prognostic outcome.Pascal Frei Benjamin Misselwitz Meher K Prakash Alain M Schoepfer Bettina M Prinz Vavricka Beat Müllhaupt Michael Fried Kuno Lehmann Rudolf W Ammann Stephan R Vavricka 2014World Journal of Gastroenterology2014,20,19:5
2Urbanization reduces resource use efficiency of phytoplankton community by altering the environment and decreasing biodiversity显示文摘Urbanization often exerts multiple effects on aquatic and terrestrial organisms,including changes in biodiversity,species composition and ecosystem functions.However,the impacts of urbanization on river phytoplankton in subtropical urbanizing watersheds remain largely unknown.Here,we explored the effects of urbanization on phytoplankton community structure(i.e.,biomass,community composition and diversity)and function(i.e.,resource use efficiency)in a subtropical river at watershed scale in southeast China over 6 years.A total of 318 phytoplankton species belonging into 120 genera and 7 phyla were identified from 108 samples.Bacillariophyta biomass showed an increasing trend with increasing urbanization level.The phytoplankton community shifted from Chlorophyta dominance in rural upstream waters to Bacillariophyta dominance in urbanized downstream waters.Furthermore,phytoplankton diversity and resource use efficiency(RUE=phytoplankton biomass/total phosphorus)were significantly decreased with increasing urbanization level from upstream to downstream.Phytoplankton RUE exhibited a significant positive correlation with species richness,but a negative correlation with phytoplankton evenness.The variation in environmental factors(turbidity,total nitrogen,NH_(4)^(+)-N,total phosphorus,PO_(4)^(3-)-P and percentage urbanized area)was significantly correlated with phytoplankton diversity and RUE.Overall,our results revealed the influence of urbanization on phytoplankton community structure and ecosystem function was due to its altering the environmental conditions.Therefore,human-driven urbanization may play crucial roles in shaping the structure and function of phytoplankton communities in subtropical rivers,and the mechanism of this process can provide important information for freshwater sustainable uses,watershed management and conservation.Yigang Yang Huihuang Chen Mamun Abdullah Al Jean Claude Ndayishimiye Jun R Yang Alain Isabwe Anqi Luo Jun Yang 2022Journal of Environmental Sciences2022,34,2:4
3Prevalence and virological profiles of hepatitis B infection in human immunodeficiency virus patients显示文摘AIM: To determine the prevalence of hepatitis B virus (HBV) in adult human immunodeficiency virus (HIV) patients with CD4+ T-cell count less than 500/mm 3 and without antiretroviral therapy; to describe different HBV-HIV coinfection virological profiles; and to search for factors associated with HBs antigen (HBsAg) presence in these HIV positive patients.METHODS: During four months (June through September 2006), 491 patients were received in four HIV positive monitoring clinical centers in Abidjan. Inclusion criteria: HIV-1 or HIV-1 and 2 positive patients, age ≥ 18 years, CD4+ T-cell count < 500/mL and formal and signed consent of the patient. Realized blood tests included HIV serology, CD4+ T-cell count, quantitative HIV RNA load and HBV serological markers, such as HBsAg and HBc antibody (anti-HBcAb). We performed HBeAg, anti-HBe antibody (anti-HBeAb), anti-HBc IgM and quantitative HBV DNA load in HBsAg positive patients. Anti-HBsAb had been tested in HIV patients with HBsAg negative and anti-HBcAb-positive. HBV DNA was also tested in 188 anti-HBcAb positive patients with HBsAg negative status and without anti-HBsAb. Univariate analysis (Pearsonχ 2 test or Fischer exact test) and multivariate analysis (backward step-wise selection logistic regression) were performed as statistical analysis. RESULTS: Mean age of 491 patients was 36 ± 8.68 years and 73.3% were female. Type-1 HIV was found in 97% and dual-type HIV (type 1 plus type 2) in 3%. World Health Organization (WHO) clinical stage was 1, 2, 3 and 4 respectively in 61 (12.4%), 233 (47.5%), 172 (35%) and 25 patients (5.1%). Median CD4+ T-cell count was 341/mm 3 (interquartile range: 221-470). One hundred and twelve patients had less than 200 CD4+ T-cell/mm 3 . Plasma HIV-1 RNA load was elevated (≥ 5 log 10 copies/mL) in 221 patients (45%). HBsAg and anti-HBcAb prevalence was respectively 13.4% and 72.9%. Of the 66 HBsAg positive patients, 22 were inactive HBV carriers (33.3%), 21 had HBeAg positive hepatitis (31.8%) and 20 had HBeAg negative hepatitis (30.3%). HBeAg and anti-HBeAb were indeterminate in 3 of them. Occult B infection prevalence (HBsAg negative, anti-HBcAb positive, anti-HBsAb negative and detectable HBV DNA) was 21.3%. Three parameters were significantly associated with the presence of HBsAg: male [odds ratio (OR): 2.2;P = 0.005; 95% confidence interval (CI): 1.3-3.8]; WHO stage 4 (OR: 3.2;P = 0.01;95% CI: 1.3-7.9); and aspartate aminotransferase (AST) level higher than the standard (OR: 1.9;P = 0.04; 95% CI: 1.02-3.8). CONCLUSION: HBV infection prevalence is high in HIV-positive patients. HBeAg positive chronic hepatitis and occult HBV infection are more frequent in HIVpositive patients than in HIV negative ones. Parameters associated with HBsAg positivity were male gender, AIDS status and increased AST level.Koffi Alain Attia Serge Eholié Eugène Messou Christine Danel Sandrine Polneau Henri Chenal Thomas Toni Myreille Mbamy Catherine Seyler Naomi Wakasugi Thérèse N'dri-Yoman Xavier Anglaret 2012World Journal of Hepatology2012,4,7:4
4Ribavirin:Past,present and future显示文摘Before the advent of direct acting antiviral agents(DAAs) ribavirin, associated to pegylated-interferon played a crucial role in the treatment of chronic hepatitis C, preventing relapses and breakthroughs. In the present era of new potent DAAs, a place is still devoted to the drug. Ribavirin associated with sofosbuvir alone is efficient in the treatment of most cases of G2 infected patients. All options currently available for the last difficult-to-treat cirrhotic G3 patients contain ribavirin. Reducing treatment duration to 12 wk in G1 or G4 cirrhotic compensated patients is feasible thanks to ribavirin. Retreating patients with acquired anti NS5 A resistance-associated variants using ribavirin-based strategies could be useful. The addition of ribavirin with DAAs combinations however, leads to more frequent but mild adverse events especially in cirrhotic patients. Preliminary data with interferon-free second generation DAAs combinations without ribavirin suggest that future of the drug is jeopardized even in difficult-totreat patients: The optimization of ribavirin dosage according to an early monitoring of blood levels has been suggested to be relevant in double therapy with peginterferon or sofosbuvir but not with very potent combinations of more than two DAAs.Véronique Loustaud-Ratti Marilyne Debette-Gratien Jérémie Jacques Sophie Alain Pierre Marquet DenisSautereau Annick Rousseau Paul Carrier 2016World Journal of Hepatology2016,8,2:3
