| 1 | IL28B polymorphism and cytomegalovirus predict response to treatment in Egyptian HCV type 4 patients显示文摘AIM:To test whether the status of positive cytomegalovirus(CMV) DNA detection adds to the predictive value of IL28B and to further categorize C/T allele carriers.METHODS:This study included 166 chronic hepatitis C(CHC) patients who received combined interferon and ribavirin therapy for 48 wk,84 spontaneous hepatitis C virus(HCV) resolvers who were positive for IgG anti-HCV antibody and negative for HCV RNA,and 100 healthy subjects who were negative for both HCV antibodies and RNA as controls.Genomic DNA from peripheral blood was used for IL28B rs.12979860 single nucleotide polymorphism(SNP) and CMV DNA detection.A 139 bp fragment containing IL28B SNP was amplified in all subjects by polymerase chain reaction using a specifically designed primer.Then the IL28B rs.12979860 SNP was detected by restriction fragment length polymorphism(RFLP) genotyping.The presence of CMV DNA was tested by amplification of the gB1 gene using nested polymerase chain reaction.The role of CMV and IL28B rs.12979860 SNP genotypes in determining the response rate to combined interferon therapy and clinical status of patients were statistically analyzed.RESULTS:Current data showed that 67% of patients carrying the IL28B 12979860 C/C allele had a sustained viral response(SVR) while the genotypes C/T and TT were associated with lower SVR rates,50% and 48%,respectively.SVR rates for the C/C allele were lower than other HCV genotypes and/or other populations.Genotype CC was associated with the response to interferon(P = 0.025).Genotype C/C was reduced from 48% in controls to 14% in CHC patients suggesting its protective role against progression to chronicity.The majority of spontaneously cleared subjects(86%) were C/C,confirming its protective role.The C/T allele was present in 71% of CHC patients compared with 38% of controls,so the use of IL28B SNP genotyping only in these patients may be of little value as a predictor of response.CMV reactivation occurred in 40% of CHC patients.Co-infection with CMV seriously diminished the response to interferon(IFN) therapy,with SVR rates in C/C genotypes 87.5% in CMV-negative patients and 12.5% in CMV-positive patients(P < 0.0001).SVR rates among C/T carriers were reduced to < 50% in patients with positive CMV DNA while the non-response rate doubled.These data indicate that a supplemental assay for CMV viremia adds to the prognostic value of IL28B genotyping.CONCLUSION:The results suggest that both genetic(i.e.,spontaneous) and therapeutic(IFN-based therapy) arms are complementary in the battle against HCV.CMV DNA testing may be of value to better predict the response to IFN,particularly in IL28B C/T carriers. | Mostafa K El Awady Noha G Bader El Din Ashraf Tabll Yaser El Hosary Ashraf O Abdel Aziz Hesham El Khayat Mohsen Salama Tawfeek H Abdelhafez | 2013 | World Journal of Gastroenterology2013,19,2: | 8 |
| 2 | Tumor necrosis factor-α-G308A polymorphism is associated with liver pathological changes in hepatitis C virus patients显示文摘AIM To investigate the association of tumor necrosis factor alpha(TNFα)-G308 A polymorphism with different liver pathological changes in treatment-na?ve Egyptian patients infected with hepatitis C virus(HCV) genotype 4.METHODS This study included 180 subjects,composed of 120 treatment-na?ve chronic HCV patients with different fibrosis grades(F0-F4) and 60 healthy controls. The TNFα-G308 A region was amplified by PCR and the different genotypes were detected by restriction fragment length polymorphism analysis. The TNFα protein was detected by enzyme-linked immunosorbent assay. The influence of different TNFα-G308 A genotypes on TNFα expression and liver disease progression were statistically analyzed. The OR and 95%CI were calculated to assess the relative risk confidence.RESULTS Current data showed that the TNFα-G308 A SNP frequency was significantly different between controls and HCV infected patients(P = 0.001). Both the AA genotype and A allele were significantly higher in late fibrosis patients(F2-F4,n = 60) than in early fibrosis patients(F0-F1,n = 60)(P = 0.05,0.04 respectively). Moreover,the GA or AA genotypes increased the TNFα serum level greater than the GG genotype(P = 0.002). The results showed a clear association between severe liver pathological conditions(inflammation,steatosis and fibrosis) and(GA + AA) genotypes(P = 0.035,0.03,0.04 respectively). The stepwise logistic regression analysis showed that the TNFα genotypes(GA + AA) were significantly associated with liver inflammation(OR = 3.776,95%CI: 1.399-10.194,P = 0.009),severe steatosis(OR = 4.49,95%CI: 1.441-14.0,P = 0.010) and fibrosis progression(OR = 2.84,95%CI: 1.080-7.472,P = 0.034). Also,the A allele was an independent risk factor for liver inflammation(P = 0.003),steatosis(P = 0.003) and fibrosis(P = 0.014). CONCLUSION TNFα SNP at nucleotide-308 represents an important genetic marker that can be used for the prognosis of different liver pathological changes in HCV infected | Noha G Bader El Din Sally Farouk Reem El-Shenawy Marwa K Ibrahim Reham M Dawood Mostafa M Elhady Ahmed M Salem Naglaa Zayed Ahmed Khairy Mostafa K El Awady | 2016 | World Journal of Gastroenterology2016,22,34: | 3 |
| 3 | Factor analysis identifies subgroups of constipation显示文摘AIM:To determine whether distinct symptom groupings exist in a constipated population and whether such grouping might correlate with quantifiable pathophysiological measures of colonic dysfunction.METHODS:One hundred and ninety-one patients presenting to a Gastroenterology clinic with constipation and 32 constipated patients responding to a newspaper advertisement completed a 53-item,wide-ranging selfreport questionnaire.One hundred of these patients had colonic transit measured scintigraphically.Factor analysis determined whether constipation-related symptoms grouped into distinct aspects of symptomatology.Cluster analysis was used to determine whether indi-vidual patients naturally group into distinct subtypes.RESULTS:Cluster analysis yielded a 4 cluster solution with the presence or absence of pain and laxative unresponsiveness providing the main descriptors.Amongst all clusters there was a considerable proportion of patients with demonstrable delayed colon transit,irritable bowel syndrome positive criteria and regular stool frequency.The majority of patients with these characteristics also reported regular laxative use.CONCLUSION:Factor analysis identified four constipation subgroups,based on severity and laxative unresponsiveness,in a constipated population.However,clear stratification into clinically identifiable groups remains imprecise. | Philip G Dinning Mike Jones Linda Hunt Sergio E Fuentealba Jamshid Kalanter Denis W King David Z Lubowski Nicholas J Talley Ian J Cook | 2011 | World Journal of Gastroenterology2011,17,11: | 3 |

| 11 | Paediatric and adult colonic manometry: A tool to help unravel the pathophysiology of constipation显示文摘Colonic motility subserves large bowel functions, including absorption, storage, propulsion and defaecation. Co-lonic motor dysfunction remains the leading hypothesis to explain symptom generation in chronic constipation, a heterogeneous condition which is extremely prevalent in the general population, and has huge socioeconomic impact and individual suffering. Physiological testing plays a crucial role in patient management, as it is now accepted that symptom-based assessment, although im-portant, is unsatisfactory as the sole means of directing therapy. Colonic manometry provides a direct method for studying motor activities of the large bowel, and this review provides a contemporary understanding of how this technique has enhanced our knowledge of normalcolonic motor physiology, as well as helping to elucidate pathophysiological mechanisms underlying constipation. Methodological approaches, including available catheter types, placement technique and recording protocols, are covered, along with a detailed description of re-corded colonic motor activities. This review also criti-cally examines the role of colonic manometry in current clinical practice, and how manometric assessment may aid diagnosis, classification and guide therapeutic inter-vention in the constipated individual. Most importantly, this review considers both adult and paediatric patients. Limitations of the procedure and a look to the future are also addressed. | Philip G Dinning Marc A Benninga Bridget R Southwell S Mark Scott | 2010 | World Journal of Gastroenterology2010,16,41: | 1 |
