1Hepatic echinococcosis:Clinical and therapeutic aspects显示文摘Echinococcosis or hydatid disease(HD)is a zoonosis caused by the larval stages of taeniid cestodes belonging to the genus Echinococcus.Hepatic echinococcosis is a life-threatening disease,mainly differentiated into alveolar and cystic forms,associated with Echinoccus multilocularis(E.multilocularis)and Echinococcus granulosus(E.granulosus)infection,respectively.Cystic echinococcosis(CE)has a worldwide distribution,while hepatic alveolar echinococcosis(AE)is endemic in the Northern hemisphere,including North America and several Asian and European countries,like France,Germany and Austria.E.granulosus young cysts are spherical,unilocular vesicles,consisting of an internal germinal layer and an outer acellular layer.Cyst expan-sion is associated with a host immune reaction and the subsequent development of a fibrous layer,called the pericyst;old cysts typically present internal septations and daughter cysts.E.multilocularis has a tumorlike,infiltrative behavior,which is responsible for tissue destruction and finally for liver failure.The liver is the main site of HD involvement,for both alveolar and cystic hydatidosis.HD is usually asymptomatic for a long period of time,because cyst growth is commonly slow;the most frequent symptoms are fatigue and abdominal pain.Patients may also present jaundice,hepatomegaly or anaphylaxis,due to cyst leakage or rupture.HD diagnosis is usually accomplished with the combined use of ultrasonography and immunodiagnosis;furthermore,the improvement of surgical techniques,the introduction of minimally invasive treatments[such as puncture,aspiration,injection,re-aspiration(PAIR)]and more effective drugs(such as benzoimidazoles)have deeply changed life expectancy and quality of life of patients with HD.The aim of this article is to provide an up-todate review of biological,diagnostic,clinical and therapeutic aspects of hepatic echinococcosis.Giuseppe Nunnari Marilia R Pinzone Salvatore Gruttadauria Benedetto M Celesia Giordano Madeddu Giulia Malaguarnera Piero Pavone Alessandro Cappellani Bruno Cacopardo 2012World Journal of Gastroenterology2012,18,13:72
2Anti-tumor necrosis factor α therapy associates to type 17 helper T lymphocytes immunological shift and significant microbial changes in dextran sodium sulphate colitis显示文摘BACKGROUND Anti-tumor necrosis factor α(TNFα) represents the best therapeutic option to induce mucosal healing and clinical remission in patients with moderate-severe ulcerative colitis. On the other side gut microbiota plays a crucial role in pathogenesis of ulcerative colitis but few information exists on how microbiota changes following anti-TNFα therapy and on microbiota role in mucosal healing.AIM To elucidate whether gut microbiota and immune system changes appear following anti TNFα therapy during dextran sulfate sodium(DSS) colitis.METHODS Eighty C57 BL/6 mice were divided into four groups: 'No DSS', 'No DSS + antiTNFα', 'DSS' and 'DSS + anti-TNFα'. 'DSS' and 'DSS + anti-TNFα' were treated for 5 d with 3% DSS. At day 3, mice whithin 'No DSS+anti-TNFα' and'DSS+anti-TNFα' group received 5 mg/kg of an anti-TNFα agent. Forty mice were sacrificed at day 5, forty at day 12, after one week of recovery post DSS. The severity of colitis was assessed by a clinical score(Disease Activity Index), colon length and histology. Bacteria such as Bacteroides, Clostridiaceae, Enterococcaceae and Fecalibacterium prausnitzii(F. prausnitzii) were evaluated by quantitative PCR.Type 1 helper T lymphocytes(Th1), type 17 helper T lymphocytes(Th17) and CD4+ regulatory T lymphocytes(Treg) distributions in the mesenteric lymph node(MLN) were studied by flow cytometry.RESULTS Bacteria associated with a healthy state(i.e., such as Bacteroides, Clostridiaceae and F. prausnitzii) decreased during colitis and increased in course of anti-TNFαtreatment. Conversely, microorganisms belonging to Enterococcaceae genera,which are linked to inflammatory processes, showed an opposite trend.Furthermore, in colitic mice treated with anti-TNFα microbial changes were associated with an initial increase(day 5 of the colitis) in Treg cells and a consequent decrease(day 12 post DSS) in Th1 and Th17 frequency cells. Healthy mice treated with anti-TNFα showed the same histological, microbial and immune features of untreated colitic mice. 'No DSS + anti-TNFα' group showed a lymphomononuclear infiltrate both at 5 th and 12 th d at hematoxylin and eosin staining, an increase of in Th1 and Th17 frequency at day 12, an increase of Enterococcaceae at day 5, a decrease of Bacteroides and Clostridiaceae at day 12.CONCLUSION Anti-TNFα treatment in experimental model of colitis improves disease activity but it is associated to an increase in Th17 pathway together with gut microbiota alteration.Valentina Petito Cristina Graziani Loris R Lopetuso Marco Fossati Alessandra Battaglia Vincenzo Arena Domenico Scannone Gianluca Quaranta Andrea Quagliariello Federica Del Chierico Lorenza Putignani Luca Masucci Maurizio Sanguinetti Alessandro Sgambato Antonio Gasbarrini Franco Scaldaferri 2019World Journal of Gastroenterology2019,25,12:2
