1Relationship between vitamin D and IL-23,IL-17 and macrophage chemoattractant protein-1 as markers of fibrosis in hepatitis C virus Egyptians显示文摘AIM:To assess vitamin D in hepatitis C patients and its relationship to interleukin (IL)-23, IL-17, and macrophage chemoattractant protein-1 (MCP-1). METHODS:The study was conducted on 50 Egyptian hepatitis C virus (HCV) genotype number IV-infected patients and 25 ageand gender-matched healthy subjects. Venous blood samples were obtained. Samples were allowed to clot and sera were separated by centrifugation and stored at -20 ℃. A 25 hydroxy vitamin D assay was carried out using solid phase RIA. A 1,25 dihydroxy vitamin D assay was carried out using a commercial kit purchased from Incstar Corporation. IL-17 and -23 and MCP-1 were assayed by an enzyme immunoassay. Quantitative and qualitative polymerase chain reaction for HCV virus were done by TaqMan technology. Only HCV genotype IV-infected subjectswere included in the study. The mean ± SD were determined, a t-test for comparison of means of different parameters was used. Correlation analysis was done using Pearson's correlation. Differences among different groups were determined using the Kruskal-Wallis test. RESULTS:The mean vitamin D level in HCV patients (groupⅠ) was 15 ± 5.2 ng/mL while in control (group Ⅱ) was 39.7 ± 10.8. For active vitamin D in groupⅠas 16.6 ± 4.8 ng/mL while in group Ⅱ was 41.9 ± 7.9. IL-23 was 154 ± 97.8 in group Ⅰ and 6.7 ± 2.17 in group Ⅱ. IL-17 was 70.7 ± 72.5 in cases and 1.2 ± 0.4 in control. MCP-1 was 1582 ± 794.4 in group Ⅰand 216.1 ± 5.38 in group Ⅱ. Vitamin D deficiency affected 72% of HCV-infected patients and 0% of the control group. Vitamin D insufficiency existed in 28% of HCV-in-fected patients and 12% of the control group. One hundred percent of the cirrhotic patients and 40% of non cirrhotic HCV-infected patients had vitamin D deficiency. IL-23, IL-17, and MCP-1 were markedly increased in HCV-infected patients in comparison to controls.A significant negative correlation between vitamin D and IL-17 and-23 and MCP-1 was detected. HCV-infected males and females showed no differences with respect to viral load, vitamin D levels, IL-17, IL-23 and MCP-1. The viral load was negatively correlated with vitamin D and active vitamin D (P = 0.0001 and P = 0.001, respectively), while positively correlated with IL-23, IL-17, and MCP-1. We classified the patients according to sonar findings into four groups. Group Ⅰa with bright hepatomegaly and included 14 patients. Group Ⅰb with perihepatic fibrosis and included 11 patients. Group Ⅰc with liver cirrhosis and included 11 patients. Group Ⅰd with he patocellular carcinoma (HCC) and included 14 patients. Vitamin D and active vitamin D were shown to be lower in cirrhotic patients and much lower in patients with HCC, and this difference was highly significant (P = 0.0001). IL-17 and-23 and MCP-1 were higher in advanced liver disease) and the differences were highly significant (P = 0.0001).CONCLUSION:Whether the deficiency of vitamin D is related to HCV-induced chronic liver disease or predisposing factor for higher viral load is a matter of debate.Noha M El Husseiny Hala M Fahmy Waleed A Mohamed Hisham H Amin 2012World Journal of Hepatology2012,4,8:12
2p53 antibodies,metallothioneins,and oxidative stress markers in chronic ulcerative colitis with dysplasia显示文摘AIM:To investigate the role of p53 antibodies (p53Abs),metallothioneins (MTs) and oxidative stress markers in the early detection of dysplasia in chronic ulcerative colitis (UC).METHODS:The study included 30 UC patients,15 without dysplasia (group Ⅱ) and 15 with dysplasia (group Ⅲ),in addition to 15 healthy volunteers (group Ⅰ,control subjects).The enzyme-linked immunosorbent assay technique was used to measure serum p53Abs and MTs,while advanced oxidation protein products (AOPPs),and reduced glutathione (GSH) levels were measured by spectrophotometric method in all subjects.RESULTS:In group Ⅱ and group Ⅲ compared to group Ⅰ,there were significant increases in serum levels of AOPPs (145.94 ± 29.86 μmol/L and 192.21 ± 46.71 μmol/L vs 128.95 ± 3.06 μmol/L,P < 0.002 and P <0.001,respectively),MTs (8.18 ± 0.35 μg/mL and 9.20 ± 0.58 μg/mL vs 6.12 ± 0.25 μg/mL,P < 0.05 and P < 0.05,respectively),and p53Abs (20.19 ± 3.20 U/mL and 34.66 ± 1.34 U/mL vs 9.42 ± 1.64 U/mL,P < 0.001 and P < 0.001,respectively).There were significantly higher levels of AOPPs (P < 0.05) and p53Abs (P < 0.001) in UC patients with dysplasia compared to those without dysplasia,while MTs showed no significant difference between the 2 groups (P > 0.096).In contrast,GSH levels showed a significant decrease in both patients' groups (1.87 ± 0.02 μmol/mL and 1.37 ± 0.09 μmol/mL vs 2.49 ± 0.10 μmol/mL,P < 0.05 and P < 0.05 in groups Ⅱ and Ⅲ,respectively) compared with group Ⅰ,and the levels were significantly lower in group Ⅲ than group Ⅱ (P < 0.05).There was a positive correlation between AOPPs and both MTs (r=0.678,P < 0.001) and p53Abs (r=0.547,P < 0.001),and also between p53Abs and MTs (r=0.739,P < 0.001).There was a negative correlation between AOPPs and GSH (r =-0.385,P < 0.001),and also between GSH and both MTs (r=-0.662,P < 0.001) and p53Abs (r=-0.923,P < 0.001).CONCLUSION:Oxidative stress and oxidative cellular damage play an important role in the pathogenesis of chronic UC and the associated carcinogenetic process.p53Abs levels could help in early detection of dysplasia in these conditions.Hala E Hamouda Soha S Zakaria Saber A Ismail Mahmoud A Khedr Wael W Mayah 2011World Journal of Gastroenterology2011,17,19:5
3Drainage vs. non-drainage after cholecystectomy for acute cholecystitis:a retrospective study显示文摘Many surgeons practice prophylactic drainage after cholecystectomy without reliable evidence,this study was conducted to answer the question whether to drain or not to drain after cholecystectomy for acute calculous cholecystitis.A retrospective review of all patients who had cholecystectomy for acute cholecystitis in Aseer Central Hospital,Abha,Saudi Arabia,was conducted from April 2010 to April 2012.Data were extracted from hospital case files.Preoperative data included clinical presentation,routine investigations and liver function tests.Operative data included excessive adhesions,bleeding,bile leak,and drain insertion.Complicated cases such as pericholecystic collections,mucocele and empyema were also reported.Patients who needed therapeutic drainage were excluded.Postoperative data included hospital stay,volume of drained fluid,time of drain removal,and drain site problems.The study included 103 patients allocated into two groups;group A(n = 38) for patients with operative drain insertion and group B(n = 65) for patients without drain insertion.The number of patients with preoperative diagnosis of acute non-complicated cholecystitis was significantly greater in group B(80%) than group A(36.8%)(P < 0.001).Operative time was significantly longer in group A.All patients who were converted from laparoscopic to open cholecystectomy were in group A.Multivariate analysis revealed that hospital stay was significantly(P < 0.001) longer in patients with preoperative complications.There was no added benefit for prophylactic drain insertion after cholecystectomy for acute calculous cholecystitis in non-complicated or in complicated cases.Mohammed A Bawahab Walid M Abd El Maksoud Saeed A Alsareii Fahad S Al Amri Hala F Ali Abdul Rahman Nimeri Abdul Rahman M Al Amri Adel A Assiri Mohammed I Abdul Aziz 2014The Journal of Biomedical Research2014,28,3:3
