| 1 | Helicobacter pylori infection as a cause of iron deficiency anaemia of unknown origin显示文摘AIM: To assess the aetiological role of Helicobacter pylori (H. pylori) infection in adult patients with ironrefractory or iron-dependent anaemia of previously unknown origin. METHODS: Consecutive patients with chronic irondeficient anaemia (IDA) with H. pylori infection and a negative standard work-up were prospectively evaluated. All of them had either iron refractoriness or iron dependency. Response to H. pylori eradication was assessed at 6 and 12 mo from follow-up. H. pylori infection was considered to be the cause of the anaemia when a complete anaemia resolution without iron supplements was observed after eradication. RESULTS: H. pylori was eradicated in 88 of the 89 patients. In the non-eradicated patient the four eradicating regimens failed. There were violations of protocol in 4 patients, for whom it was not possible to ascertain the cause of the anaemia. Thus, 84 H. pylori eradicated patients (10 men; 74 women) were available to assess the effect of eradication on IDA. H. pylori infection was considered to be the aetiology of IDA in 32 patients (38.1%; 95%CI: 28.4%-48.8%). This was more frequent in men/postmenopausal women than in premenopausal women (75% vs 23.3%; P < 0.0001) with an OR of 9.8 (95%CI: 3.3-29.6). In these patients, anaemia resolution occurred in the first follow-up visit at 6 mo, and no anaemia or iron deficiency relapse was observed after a mean follow-up of 21 ± 2 mo. CONCLUSION: Gastric H. pylori infection is a frequent cause of iron-refractory or iron-dependent anaemia of previously unknown origin in adult patients. | Helena Monzón Montserrat Forné Maria Esteve Mercé Rosinach Carme Loras Jorge C Espinós Josep M Viver Antonio Salas Fernando Fernández-Baares | 2013 | World Journal of Gastroenterology2013，19，26： | 13 |
| 2 | Cytokine production in patients with cirrhosis and TLR4 polymorphisms显示文摘AIM:To analyze the cytokine production by peripheral blood cells from cirrhotic patients with and without TLR4 D299G and/or T399I polymorphisms.METHODS:The study included nine patients with cirrhosis and TLR4 D299G and/or T399I polymorphisms,and 10 wild-type patients matched for age,sex and degree of liver failure.TLR4 polymorphisms were determined by sequence-based genotyping.Cytokine production by peripheral blood cells was assessed spontaneously and also after lipopolysaccharide(LPS)and lipoteichoic acid(LTA)stimulation.RESULTS:Patients with TLR4 polymorphisms had a higher incidence of previous hepatic encephalopathy than wild-type patients(78%vs 20%,P=0.02).Spontaneous production of interleukin(IL)-6 and IL-10 was lower in patients with TLR4 polymorphisms than in wild-type patients[IL-6:888.7(172.0-2119.3)pg/m L vs 5540.4(1159.2-26053.9)pg/m L,P<0.001;IL-10:28.7(6.5-177.1)pg/m L vs 117.8(6.5-318.1)pg/m L,P=0.02].However,the production of tumor necrosis factor-α,IL-6 and IL-10 after LPS and LTA stimulation was similar in the two groups.CONCLUSION:TLR4 polymorphisms were associated with a distinctive pattern of cytokine production in cirrhotic patients,suggesting that they play a role in the development of cirrhosis complications. | Juan Camilo Nieto Elisabet Sánchez Eva Román Silvia Vidal Laia Oliva Carlos Guarner-Argente Maria Poca Xavier Torras Cándido Juárez Carlos Guarner German Soriano | 2014 | World Journal of Gastroenterology2014，20，46： | 5 |
| 3 | Potential role of imaging in assessing harmful effects on spermatogenesis in adult testes with varicocele显示文摘Varicocele is characterized by an abnormal dilatation and retrograde blood flow in the spermatic veins. Varicocele is the leading correctable cause of male infertility. Although it is highly prevalent in infertile men, it is also observed in individuals with normal fertility. Determining which men are negatively affected by varicocele would enable clinicians to better select those men who will benefit from treatment. To assess the functional status of the testes in men with varicocele, color Doppler sonographic parameters were evaluated. Testicular arterial blood flow was significantly reduced in men with varicocele, reflecting an impairment of spermatogenesis. An improvement in the testicular blood supply was found after varicocelectomy on spectral Doppler analysis. Testicular contrast harmonic imaging and elastography might improve our knowledge about the influence of varicocele on intratesticular microcirculation and tissue stiffness, respectively, providing possible information on the early damage of testicular structure by varicocele. Magnetic resonance imaging(MRI), with measurement of apparent diffusion coefficient has been used to assess the degree of testicular dysfunction and to evaluate the effectiveness of varicocele repair. Large prospective studies are needed to validate the possible role of functional sonography and MRI in the assessment of early defects of spermatogenesis in testes with varicocele. | Athina C Tsili Olga N Xiropotamou Anastasios Sylakos Vasilios Maliakas Nikolaos Sofikitis Maria I Argyropoulou | 2017 | World Journal of Radiology2017，9，2： | 4 |
| 4 | Presacral venous bleeding during mobilization in rectal cancer显示文摘AIM To analyze the anatomy of sacral venous plexus flow, the causes of injuries and the methods for controlling presacral hemorrhage during surgery for rectal cancer.METHODS A review of the databases MEDLINE? and Embase? was conducted, and relevant scientific articles published between January 1960 and June 2016 were examined. The anatomy of the sacrum and its venous plexus, as well as the factors that influence bleeding, the causes of this complication, and its surgical management were defined.RESULTS This is a review of 58 published articles on presacral venous plexus injury during the mobilization of the rectum and on techniques used to treat presacral venous bleeding. Due to the lack of cases published in the literature, there is no consensus on which is the best technique to use if there is presacral bleeding during mobilization in surgery for rectal cancer. This review may provide a tool to help surgeons make decisions regarding how to resolve this serious complication.CONCLUSION A series of alternative treatments are described; however, a conventional systematic review in which optimal treatment is identified could not be performed because few cases were analyzed in most publications. | Jose Enrique Casal Núnez Vincenzo Vigorita Alejandro Ruano Poblador Ana María Gay Fernández Maria ángeles Toscano Novella Nieves Cáceres Alvarado Lucinda Pérez Dominguez | 2017 | World Journal of Gastroenterology2017，23，9： | 4 |
| 5 | Toll-like receptor 4 polymorphisms and bacterial infections in patients with cirrhosis and ascites显示文摘AIM To assess the relationship between the presence of toll-like receptor 4(TLR4) polymorphisms and bacterial infections in cirrhotic patients with ascites. METHODS We prospectively included consecutive patients with cirrhosis and ascites hospitalized during a 6-year period. Patients with human immunodeficiency virus(HIV) infection or any other immunodeficiency, patients with advanced hepatocellular carcinoma(beyond Milan's criteria) or any other condition determining poor short-term prognosis, and patients with a permanent urinary catheter were excluded. The presence of D299 G and/or T399 I TLR4 polymorphisms was determined by sequencing and related to the incidence and probability of bacterial infections, other complications of cirrhosis, hepatocellular carcinoma, and mortality during follow-up. A multivariate analysis to identify predictive variables of mortality in the whole series was performed. RESULTS We included 258 patients: 28(10.8%) were carriers of D299G and/or T399I TLR4 polymorphisms(polymorphism group) and 230 patients were not(wildtype group). The probability of developing any bacterial infection at one-year follow-up was 78% in the polymorphism group and 69% in the wild-type group(P = 0.54). The one-year probability of presenting infections caused by gram-negative bacilli(51% vs 44%, P = 0.68), infections caused by gram-positive cocci(49% vs 40%, P = 0.53), and spontaneous bacterial peritonitis(29% vs 34%, respectively, P = 0.99) did not differ between the two groups. The oneyear probability of transplant-free survival was 55% in the polymorphism group and 66% in the wild-type group(P = 0.15). Multivariate analysis confirmed that age, Child-Pugh score, active alcohol intake, previous hepatic encephalopathy, hepatocellular carcinoma and serum creatinine were associated with a higher risk of death during follow-up. CONCLUSION Genetic polymorphisms D299 G and/or T399 I of TLR4 do not seem to play a relevant role in the predisposition of cirrhotic patients with ascites to bacterial infections. | Edilmar Alvarado-Tapias Carlos Guarner-Argente Elida Oblitas Elisabet Sánchez Silvia Vidal Eva Román Mar Concepción Maria Poca Cristina Gely Oana Pavel Juan Camilo Nieto Cándido Juárez Carlos Guarner Germán Soriano | 2018 | World Journal of Hepatology2018，10，1： | 3 |
