| 1 | Viral hepatitis prevalence in patients with active and latent tuberculosis显示文摘AIM: To assess the prevalence of hepatitis B virus(HBV) and hepatitis C virus(HCV) infection and association with drug induced liver injury(DILI) in patients undergoing anti-tuberculosis(TB) therapy.METHODS: Four hundred and twenty nine patients with newly diagnosed TB- either active disease or latent infection- who were due to commence antiTB therapy between September 2008 and May 2011 were included. These patients were prospectively tested for serological markers of HBV, HCV and human immunodeficiency virus(HIV) infections- hepatitis B core antigen(HBc Ag), hepatitis B surface antigen(HBs Ag), hepatitis B e antigen, Ig G and Ig M antibody to HBc Ag(anti-HBc), HCV Ig G antibody and HIV antibody using a combination of enzyme-linked immunosorbent assay, Western blot assay and polymerase chain reaction techniques. Patients were reviewed at least monthly during the TB treatment initiation phase. Liver function tests were measured prior to commencement of antiTB therapy and 2-4 wk later. Liver function tests were also performed at any time the patient had significant nausea, vomiting, rash, or felt non-specifically unwell. Fisher's exact test was used to measure significance in comparisons of proportions between groups. A P value of less than 0.05 was considered statistically significant.RESULTS: Of the 429 patients, 270(62.9%) had active TB disease and 159(37.1%) had latent TB infection. 61(14.2%) patients had isolated anti-HBc positivity, 11(2.6%) were also HBs Ag positive and 7(1.6%) were HCV-antibody positive. 16/270 patients with active TB disease compared to 2/159 patients with latent TB infection had markers of chronic viral hepatitis(HBs Ag or HCV antibody positive; P = 0.023). Similarly the proportion of HBs Ag positive patients were significantly greater in the active vs latent TB infection group(10/43 vs 1/29, P = 0.04). The prevalence of chronic HBV or HCV was significantly higher than the estimated United Kingdom prevalence of 0.3% for each. We found no association between DILI and presence of serological markers of HBV or HCV. Three(5.3%) patients with serological markers of HBV or HCV infection had DILI compared to 25(9.5%) patients without; P = 0.04.CONCLUSION: Viral hepatitis screening should be considered in TB patients. DILI risk was not increased in patients with HBV/HCV. | Hesam Ahmadi Nooredinvand David W Connell Mahmoud Asgheddi Mohammed Abdullah Marie O'Donoghue Louise Campbell Melissa I Wickremasinghe Ajit Lalvani Onn Min Kon Shahid A Khan | 2015 | World Journal of Gastroenterology2015，21，29： | 7 |
| 2 | Aqueous extracts of microalgae exhibit antioxidant and anticancer activities显示文摘Objective:To investigate the antioxidant and anticancer activities of aqueous extracts of nine microalgal species.Methods:Variable percentages of major secondary metabolites(total phenolic content,terpenoids and alkaloids) as well as phycobiliprotein pigments(phycocyanin, allophycocyanin and phycoerythrin) in the aqueous algal extracts were recorded.Antioxidant activity of the algal extracts was performed using 2,2 diphenyl-1-picrylhydrazyl(DPPH) test and 2,2'azino-bis(ethylbenzthiazoline-6-sulfonic acid(ABTS.) radical cation assay.Anticancer efficiency of the algal water extracts was investigated against Ehrlich Ascites Carcinoma cell(EACC) and Human hepatocellular cancer cell line(HepG2).Results:Antioxidant activity of the algal extracts was performed using DPPH test and ABTS.^+ radical cation assays which revealed 30.1-72.4%and 32.0-75.9%respectively.Anticancer efficiency of the algal water extracts was investigated against Ehdich Ascites Carcinoma Cell(EACC) and Human Hepatocellular cancer cell line(HepG2) with an activity ranged 87.25%and 89.4%respectively.Culturing the promising cyanobacteria species;Nostoc muscorum and Oscillatoria sp.under nitrogen stress conditions(increasing and decreasing nitrate content of the normal BG11 medium,1.5 g/L),increased nitrate concentration(3,6 and 9 g/L) led to a remarkable increase in phycobilin pigments followed by an increase in both antioxidant and anticancer activities in both cyanobacterial species.While the decreased nitrate concentration(0.75,0.37 and 0.0 g/L) induced an obvious decrease in phycobilin pigments with complete absence of allophycocyanin in case of Oscillatoria sp.Conclusions:Nitrogen starvation(0.00 g/L nitrate) induced an increase and comparable antioxidant and anticancer activities to those cultured in the highest nitrate content. | Sanaa MM Shanab Soha SM Mostafa Emad A Shalaby Ghada I Mahmoud | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，8： | 6 |
| 3 | Occult hepatitis B virus infection among Egyptian blood donors显示文摘AIM:To identify blood donors with occult hepatitis B virus(HBV) infection(OBI) to promote safe blood donation.METHODS:Descriptive cross sectional study was conducted on 3167 blood donors negative for hepatitis B surface antigen(HBsAg),hepatitis C antibody(HCV Ab) and human immunodeficiency virus Ab.They were subjected to the detection of alanine aminotransferase(ALT) and aspartate transaminase(AST) and screening for anti-HBV core antibodies(total) by two different techniques;[Monoliza antibodies to hepatitis B core(Anti-HBc) Plus-Bio-Rad] and(ARC-HBc total-ABBOT).Positive samples were subjected to quantitative detection of antibodies to hepatitis B surface(anti-HBs)(ETI-AB-AUK-3,Dia Sorin-Italy).Serum anti-HBs titers > 10 IU/L was considered positive.Quantitative HBV DNA by real time polymerase chain reaction(PCR)(QIAGEN-Germany) with 3.8 IU/mL detection limit was estimated for blood units with negative serum anti-HBs and also for 32 whose anti-HBs serum titers were > 1000 IU/L.Also,265 recipients were included,34 of whom were followed up for 3-6 mo.Recipients were investigated for ALT and AST,HBV serological markers:HBsAg(ETI-MAK-4,Dia Sorin-Italy),anti-HBc,quantitative detection of anti-HBs and HBV-DNA.RESULTS:525/3167(16.6%) of blood units were positive for total anti-HBc,64% of those were antiHBs positive.Confirmation by ARCHITECT anti-HBc assay were carried out for 498/525 anti-HBc positive samples,where 451(90.6%) confirmed positive.Reactivity for anti-HBc was considered confirmed only if two positive results were obtained for each sample,giving an overall prevalence of 451/3167(14.2%) for total anti-HBc.HBV DNA was quantified by real time PCR in 52/303(17.2%) of anti-HBc positive blood donors(viral load range:5 to 3.5 x 105 IU/mL) with a median of 200 IU/mL(mean:1.8 x 104 ± 5.1 x 104 IU/mL).AntiHBc was the only marker in 68.6% of donors.Univariate and multivariate logistic analysis for identifying risk factors associated with anti-HBc and HBV-DNA positivity among blood donors showed that age above thirty and marriage were the most significant risk factors for prediction of anti-HBc positivity with AOR 1.8(1.4-2.4) and 1.4(1.0-1.9) respectively.Other risk factors as gender,history of blood transfusion,diabetes mellitus,frequent injections,tattooing,previous surgery,hospitalization,Bilharziasis or positive family history of HBV or HCV infections were not found to be associated with positive anti-HBc antibodies.Among anti-HBc positive blood donors,age below thirty was the most significant risk factor for prediction of HBV-DNA positivity with AOR 3.8(1.8-7.9).According to HBV-DNA concentration,positive samples were divided in two groups;group one with HBV-DNA ≥ 200 IU/mL(n = 27) and group two with HBV-DNA < 200 IU/mL(n = 26).No significant difference was detected between both groups as regards mean age,gender,liver enzymes or HBV markers.Serological profiles of all followed up blood recipients showed that,all were negative for the studied HBV markers.Also,HBV DNA was not detected among studied recipients,none developed post-transfusion hepatitis(PTH) and the clinical outcome was good.CONCLUSION:OBI is prevalent among blood donors.Nucleic acid amplification/HBV anti core screening should be considered for high risk recipients to eliminate risk of unsafe blood donation. | Zeinab N Said Manal H El Sayed Iman I Salama Enas K Aboel-Magd Magda H Mahmoud Maged El Setouhy Faten Mouftah Manal B Azzab Heidi Goubran Amal Bassili Gamal E Esmat | 2013 | World Journal of Hepatology2013，5，2： | 4 |
| 4 | Split-dose menthol-enhanced PEG vs PEG-ascorbic acid for colonoscopy preparation显示文摘AIM:To compare the efficacy and palatability of 4L polyethylene glycol electrolyte(PEG)plus sugar-free menthol candy(PEG+M)vs reduced-volume 2 L ascorbic acid-supplemented PEG(Asc PEG).METHODS:In a randomized controlled trial setting,ambulatory patients scheduled for elective colonoscopy were prospectively enrolled.Patients were randomized to receive either PEG+M or Asc PEG,both splitdosed with minimal dietary restriction.Palatability was assessed on a linear scale of 1 to 5(1=disgusting;5=tasty).Quality of preparation was scored by assignment-blinded endoscopists using the modified Aronchick and Ottawa scales.The main outcomes were the palatability and efficacy of the preparation.Secondary outcomes included patient willingness to retake the same preparation again in the future and completion of the prescribed preparation.RESULTS:Overall,200 patients were enrolled(100patients per arm).PEG+M was more palatable than Asc PEG(76%vs 62%,P=0.03).Completing the preparation was not different between study groups(91%PEG+M vs 86%Asc PEG,P=0.38)but more patients were willing to retake PEG+M(54%vs 40%respectively,P=0.047).There was no significant difference between PEG+M vs Asc PEG in adequate cleansing on both the modified Aronchick(82%vs77%,P=0.31)and the Ottawa scale(85%vs 74%,P=0.054).However,PEG+M was superior in the left colon on the Ottawa subsegmental score(score0-2:94%for PEG+M vs 81%for Asc PEG,P=0.005)and received significantly more excellent ratings than Asc PEG on the modified Aronchick scale(61%vs 43%,P=0.009).Both preparations performed less well in afternoon vs morning examinations(inadequate:29%vs 15.2%,P=0.02).CONCLUSION:4 L PEG plus menthol has better palatability and acceptability than 2 L ascorbic acidPEG and is associated with a higher rate of excellentpreparations;Clinicaltrial.gov identifier:NCT01788709. | Ala I Sharara Ali H Harb Fayez S Sarkis Jean M Chalhoub Rami Badreddine Fadi H Mourad Mahmoud Othman Omar Masri | 2015 | World Journal of Gastroenterology2015，21，6： | 2 |
