| 1 | Expression of p53,Bax and Bcl-2 proteins in hepatocytes in non-alcoholic fatty liver disease显示文摘AIM: To analyze the protein expression essential for apoptosis in liver steatosis. METHODS: The expression of proapoptotic proteins p53, Bax, and antiapoptotic Bcl-2 in hepatocytes with steatosis (SH) and without steatosis (NSH) was evaluated in 84 patients at various stages of non-alcoholic fatty liver disease (NAFLD). RESULTS: Immunohistochemical staining of liver tissue showed the activation of p53 protein in SH and NSH with increased liver steatosis, diminished Bcl-2 and slightly decreased Bax protein. Positive correlation was found between the stage of liver steatosis with p53 expression in SH (r = 0.54, P < 0.01) and NSH (r = 0.49, P < 0.01). The antiapoptotic protein Bcl-2 was diminished together with the advancement of liver steatosis, especially in non-steatosed hepatocytes (r =0.43, P < 001). CONCLUSION: Apoptosis is one of the most important mechanisms leading to hepatocyte elimination in NAFLD. The intensification of inflammation in NAFLD induces proapoptotic protein p53 with the inhibition of antiapoptotic Bcl-2. | Anatol Panasiuk Janusz Dzieciol Bozena Panasiuk Danuta Prokopowicz | 2006 | World Journal of Gastroenterology2006，12，38： | 46 |
| 2 | Plasma matrix metalloproteinase-1 and tissue inhibitor of metalloproteinase-1 as biomarkers of ulcerative colitis activity显示文摘AIM: Overexpression of mucosal metalloproteinases (MMP)has been demonstrated recently in inflammatory boweldisease. Their activity can be counterbalanced by the tissueinhibitor of metalloproteinases (TIMP). The aim of this studywas to evaluate the effect of ulcerative colitis (UC) on MMP-1 and TTMP-1 plasma concentrations, as two possiblebiomarkers of the disease activity.METHODS: MMP-1 and TIMP-1 plasma concentrations weremeasured with an enzyme immunoassay in 16 patients withendoscopically confirmed active UC.RESULTS: Plasma concentrations of both MMP-11 (13.7±0.2ng/ml) and TIMP-L (799±140 ng/ml) were significantlyelevated in UC patients in comparison to healthy controls(11.9±0.9 ng/ml and 220±7 ng/ml respectively). There wasno correlation between TIMP-1 and MMP-1 concentrations(r=-0.02). TIMP-1 levels revealed significant positivecorrelations with scored endoscopic degree of mucosai injury,disease activity index and clinical activity index values aswell as C-reactive protein concentration. There was nocorrelation between MMP-1 and laboratory, clinical orendoscopic indices of the disease activity.CONCLUSION: These results confirm the role of both MMP-1 and TIMP-1 in the pathogenesis of ulcerative colitis.However only TIMP-1 can be useful as a biomarker of thedisease activity, demonstrating association with clinical andendoscopic pictures. | Alicja Wiercinska-Drapalo Jerzy Jaroszewicz Robert Flisiak Danuta Prokopowicz | 2003 | World Journal of Gastroenterology2003，9，12： | 21 |
| 3 | Plasma interleukin-18 reflects severity of ulcerative colitis显示文摘AIM: The aim of this study was to evaluate the association between ulcerative colitis activity and plasma or mucosal concentrations of interleukin (IL)-18.METHODS:Il-18 concentrations were measured in plasma and mucosal samples from 15 patients with active ulcerative colitis (UC).RESULTS: The mean plasma concentration of IL-18 measured in all patients (422±88 pg/mL) doubled the mean value in healthy controls (206±32 pg/mL); however,the difference was not statistically significant. Plasma IL-18 levels revealed a significant positive correlation with scored endoscopic degree of mucosal injury, disease activity index, clinical activity index and C-reactive protein concentration. The mean concentration of plasma IL-18 was significantly higher in patients with severe ulcerative colitis (535±115 pg/mL) than in patients with mild ulcerative colitis (195±41 pg/mL), and in healthy controls.Although the mucosal mean IL-18 concentration in severe ulcerative colitis (2 523±618 pg/mg protein) doubled values observed in mild one (1 347±308 pg/mg protein), there was no statistically significant difference.CONCLUSION: Plasma IL-18 can be considered as a surrogate marker helpful in evaluation of ulcerative colitis activity. | Alicja Wiercinska-Drapalo Flobert Flisiak Jerzy Jaroszewicz Danuta Prokopowicz | 2005 | World Journal of Gastroenterology2005，11，4： | 16 |
| 4 | High concentration of antimitochondrial antibodies predicts progressive primary biliary cirrhosis显示文摘AIM: To evaluate the serum concentration of antimitochondrial antibodies (AMAs) as a prognostic indicator of progressive primary biliary cirrhosis (pPBC).METHODS: Serum concentrations of AMA subtypes (anti-M2, anti-M4, and anti-M9), biochemical indices of liver function and Mayo risk factor (MRF) were determined in 30 women with diagnosed primary biliary cirrhosis (PBC) selected among 348 females with elevated alkaline phosphatase but without signs of hepatic decompensation.They were followed up for 5 years for possible development of hepatic decompensation.RESULTS: Anti-M2 concentration was significantly correlated with bilirubin and albumin levels as well as MRF, whereas anti-M4 was significantly correlated with albumin level, prothrombin time and MRF. During the 5-year follow-up, progressive PBC (pPBC) was diagnosed in 3 among 23 patients available for evaluation. These 3patients were positive for both anti-M2 and anti-M4.Anti-M2 serum concentration exceeded 1 300 RU/mL in patients with pPBC and only in 1 among 20 non-progressive PBC persons (5%). Anti-M4 serum concentration exceeded 400 RU/mL in 2 of the progressive patients and none in the non-progressive group. In contrast, anti-M9 serum concentration was below 100 RU/mL in all patients with pPBC, and higher than 100 RU/mL in 11 women (55%)among the non-progressive group.CONCLUSION: Females with elevated alkaline phosphatase and high anti-M2 and anti-M4 concentrations are at a high risk for developing pPBC. Quantitative AMA detection should be considered as a method for early diagnosis of pPBC. | Robert Flisiak Maria Pelszynska Danuta Prokopowicz Magdalena Rogalska Urszula Grygoruk | 2005 | World Journal of Gastroenterology2005，11，36： | 16 |
| 5 | Blood platelet and monocyte activations and relation to stages of liver cirrhosis显示文摘AIM: Blood platelets (plt) and monocytes are the cells that play a crucial role in the pathogenesis of liver damage and liver cirrhosis (LC). In this paper, the analysis of mutual relationship between platelets and monocytes activation in LC was conducted.METHODS: Immunofluorescent flow cytometry was usedto measure the percentage of activated platelet populations(CD62P, CD63), the percentage of plt-monocyte aggregates (pma) (CD41/CD45), and activated monocytes (CD11b, CD14, CD16) in the blood of 20 volunteers and 40 patientswith LC. Platelet activation markers: sP-selectin, platelet factor 4 (PF4), beta-thromboglobulin (βTG) and monocyte chemotactic peptide-1 (MCP-1) were measured and compared in different stages of LC.RESULTS: Platelet activation with the increase in bothβTG serum concentration and elevation of plt population(CD62P and CD63 as well as MIF CD62P and CD63) is elevated as LC develops and thrombocytopenia rises. There is a positive correlation between medial intensityof fluorescence (MIF) CD62P and MIF CD63 in LC. We did not show any relationship between monocyte activation and pma level. SP-selectin concentration correlates positively with plt count and pma, and negatively with stage of plt activation and MIF CD62P and MIF CD63. There was no correlation between MCP-1 concentration andpit, monocyte activation as well as pma level in LC. CD16 monocytes and MIF CD16 populations are significantlyhigher in the end stage of LC. A positive correlation occurs between the value of CD11b monocyte population andMIF CD14 and MIF CD16 on monocytes in LC.CONCLUSION: Platelet and monocyte activation plays an important role in LC. Platelet activation stage does not influence monocyte activation and production of plt aggregates with monocytes in LC. With LC development, thrombocytopenia may be the result of plt consumption in platelet-monocyte aggregates. | Anatol Panasiuk Janusz Zak Edwina Kasprzycka Katarzyna Janicka Danuta Prokopowicz | 2005 | World Journal of Gastroenterology2005，11，18： | 11 |
| 6 | Effect of lamivudine treatment on plasma levels of transforming growth factor β_1,tissue inhibitor of metalloproteinases-1 and metalloproteinase-1 in patients with chronic hepatitis B显示文摘AIM: Transforming growth factor (TGF)-β1, metalloproteinase (MMP)-1 and its tissue inhibitor (TIMP)-I are considered predictive biomarkers of chronic hepatitis activity and fibrosis.The aim of this study was to evaluate the effect of lamivudine treatment on the plasma levels of these peptides in patients with chronic hepatitis B.METHODS: TGF-β1, MMP-1 and TIMP-1 plasma concentrations were measured with an enzyme immunoassay in 40 patients treated with lamivudine for 48 wk. Elimination of HBV-DNA and HBV antigens was evaluated 24 wk after treatment completion.RESULTS: Baseline TGF-β1(29.6±2.2 ng/mL) and TIMP-1(1 578±93 ng/mL) significantly exceeded normal values(18.3±1.6 ng/mL and 1 102±67 ng/mL respectively). Lamivudine treatment resulted in a significant decrease of TGF-β1 and TIMP-1 during treatment with an increase after 24 wk of treatment. Pretreatment MMP-1 levels (6.7±0.7 ng/mL) were significantly lower than normal values (11.9±0.9 ng/mL) and increased during treatment and follow-up. A significant correlation was noted between TGF-β1 or TIMP-1 and aminotransferases as well as fibrosis scored in liver biopsy specimens. There were no statistically significant differences of TGF-β1, TIMP-1 and MMP-1 between four groups at baseline, 24 and 48 wk of treatment. TGF-β1 and TIMP-1 levels increased significantly in non-responders and normalized in responders at wk 72. MMP-1 also normalized in responders and decreased to values significantly lower than normal in non-responders.CONCLUSION: These findings support the role of TGF-β1,TIMP-1 and MMP-1 in the pathogenesis of chronic hepatitis B.Because of their association with hepatic injury and antiviral treatment efficacy, determination of these peptides may be useful in disease management. | Robert Flisiak Haza Al-Kadasi Jerzy Jaroszewicz Danuta Prokopowicz Iwona Flisiak | 2004 | World Journal of Gastroenterology2004，10，18： | 7 |
| 7 | Serum concentration of sFas and sFasL in healthy HBsAg carriers,chronic viral hepatitis B and C patients显示文摘AIM: To estimate the amount of apoptosis among healthy HBsAg carriers, patients with chronic HBV infection treated with lamivudine and patients with chronic HCV infedJon treated with interferon alpha and ribavirin. Activity of apoptosis was evaluated by serum sFas/sFasL concentration measurement.Moreover dependence between apoptosis and HBV-DNA or HCV-RNA levels was studied.METHODS: Eighty-six persons were included into study: 34 healthy HBsAg carriers, 33 patients with chronic HBV infection and 19 patients with chronic HCV infection. Serum levels of sFas/sFasL were measured by ELISA assay. HBV-DNA and HCV-RNA were measured by RT-PCR assay. Levels of sFas/sFasL were determined before and 2 and 12 wk after therapy in patients with chronic hepatitis B and C infection.HBV-DNA or HCV-RNA was detected before treatment and 6 mo after treatment.RFSULTS: Twenty-four (71%) healthy HBsAg carriers showed HBV-DNA over 10^5/mL, which was comparable to the patients with chronic hepatitis B. Independently from HBV-DNA levels,the concentration of sFas among healthy HBsAg carriers was comparable to healthy persons. Among patients with chronic hepatitis B and C, the concentration of sFas was significantly higher in comparison to healthy HBsAg carriers and healthy persons. In chronic hepatitis B patients the concentration of sFas was decreased during lamivudine treatment. Among chronic hepatitis C patients the concentration of sFas was increased during IFN alpha and ribavirin treatment, sFasL was not detected in control group. Furthermore sFasL oo:urred more frequently in chronic hepatitis C patients in comparison to chronic hepatitis B patients.CONCLUSION: There are no correlations between apoptosis and HBV-DNA levels. However ther is an association between apoptosis and activity of inflammation in patients with chronic HBV infection. Apoptosis can be increased in patients with chronic hepatitis C by effective treatment which may be a result of apoptosis stimulation by IFN-α. | Tadeusz Wojciech Lapinski Oksana Kowalczuk Danuta Prokopowicz Lech Chyczewski | 2004 | World Journal of Gastroenterology2004，10，24： | 7 |
| 8 | Phagocytic and oxidative burst activity of neutrophils in the end stage of liver cirrhosis显示文摘AIM: To evaluate the phagocytic activity and neutrophil oxidative burst in liver cirrhosis.METHODS: In 45 patients with advanced postalcoholic liver cirrhosis (aged 45±14 years) and in 25 healthy volunteers (aged 38±5 years), the percentage of phagocytizing cells after in vitro incubation with E. coli (Phagotest Kit), phagocytic activity (mean intensity of fluorescence, MIF) and the percentage of neutrophil oxidative burst (Bursttest Kit), and the level of free oxygen radical production (MIF of Rodamine 123)were analyzed by flow cytometry. The levels of soluble sICAM-1, sVCAM-1, sP-selectin, sE-selectin, sL-selectin,and TNF-α were determined in blood serum.RESULTS: The percentage of E. coli phagocytizing neutrophils in liver cirrhosis patients was comparable to that in healthy subjects. MIF of neutrophil - ingested E. coli was higher in patients with liver cirrhosis. The oxidative burst in E. coli phagocytizing neutrophils generated less amount of active oxygen compounds in liver cirrhosis patients (MIF of R123:24.7±7.1 and 29.7±6.6 in healthy,P<0.01). Phorbol myristate acetate (PMA) - stimulated neutrophilsproduced less reactive oxidants in liver cirrhosis patients than in healthy subjects (MIF of R123: 42.7±14.6 vs 50.2±13.3, P<0.01). A negative correlation was observed between oxidative burst MIF of PMA-stimulated neutrophils and ALT and AST levels (r -0.35, P<0.05;r-0.4, P<0.03). sVCAM-1, sICAM-1, sE-selectin concentrations correlated negatively with the oxygen free radical production (MIF of R123) in neutrophils after PMA stimulation in liver cirrhosis patients (r-0.45, P<0.05;r-0.41, P<0.05; r-0.39, P<0.05, respectively).CONCLUSION: Neutrophil metabolic activity diminishes together with the intensification of liver failure. The metabolic potential of phagocytizing neutrophils is significantly lower in liver cirrhosis patients, which can be one of the causes of immune mechanism damage. The evaluation of oxygen metabolism of E. coli-stimulated neutrophils reveals that the amount of released oxygen metabolites is smaller in liver cirrhosis patients than in healthy subjects. | Anatol Panasiuk Jolanta Wysocka Elzbieta Maciorkowska Bozena Panasiuk Danuta Prokopowicz Janusz Zak Karol Radomski | 2005 | World Journal of Gastroenterology2005，11，48： | 4 |
| 9 | Epidemiological characteristics of inflammatory bowel disease in North-Eastern Poland显示文摘AIM: To provide the clinical and epidemiological data of inflammatory bowel disease (IBD) patients of NorthEastern Poland.METHODS: A total of 248 IBD patients diagnosed and hospitalized in the Department of Infectious Diseases in Bialystok between 1990 and 2003 were included in the study. We analyzed age, sex, education, characteristics of job, type of the environment, discontinuation of employment due to IBD, colitis extent, need of surgical treatment, and coexistence of other diseases.RESULTS: Two hundred and thirty-three IBD patients (94%) were diagnosed as ulcerative colitis (UC), and only 15 (6%) were diagnosed as Crohn's disease (CD). Patients with CD were significantly younger at the time of diagnosis and male predominance was observed. The mean age of the patients at the time UC diagnosis was 44.9±1.1 years. Histogram of the age of patients showed the characteristic biphasic distribution with two peaks between 20 and 40 years and between 60 and 70 years. The predominant form of UC was left sided colitis, which affected almost 80% of the studied population. The most extensive form - pancolitis was present in 34 patients (15%). Only 6% of UC patients required surgery, whereas 36% of CD patients underwent surgery (P<0.005). Among coexisting disorders, cholelithiasis was the most prevalent and demonstrated in 35 patients (14%), pulmonary disorders were diagnosed in 2%, and psoriasis in 1.4%.Since 1998, the number of admitted IBD patients has slightly increased.CONCLUSION: Occurrence of UC in Poland is much higher than that of CD. The majority of UC cases are diagnosed in young people (20-40 years) with the predominance of male patients. The most common clinical form of UC is left sided colitis. | Alicja Wiercinska-Drapalo Jerzy Jaroszewicz Robert Flisiak Danuta Prokopowicz | 2005 | World Journal of Gastroenterology2005，11，17： | 3 |
| 10 | Expression of β2-integrin on leukocytes in liver cirrhosis显示文摘AIM: To analyze β2-integrin expression on blood leukocytes in liver cirrhosis. METHODS: In 40 patients with liver cirrhosis and 20 healthy individuals, the evaluation of expression of CD11a (LFA-1α), CD11b (Mac-1α), CD11c (αX) and CD49d (VLA-4α) on peripheral blood leukocytes was performed using flow cytometry. The analysis was carried out in groups of patients divided into B and C according to Child-Pugh’s classification. RESULTS: An increased CD11a, CD11b, CD11c and CD49d integrin expression was observed on peripheral blood leukocytes in liver cirrhosis. The integrin levels were elevated as the advancement of liver failure progressed. The highest expression of integrins occurred predominantly on monocytes. A slight expression of VLA-4 was found on lymphocytes and granulocytes and it increased together with liver failure. A positive correlation was noted between median intensity of fluorescence (MIF) expression on polymorphonuclear cells of CD11a and CD11c and CD49d (r = 0.42, P < 0.01; r = 053, P < 0.01, respectively) in liver cirrhosis stage C. However, no correlation was observed between integrin expression on leukocytes. The concentrations of sICAM-1, sVCAM-1, and TNFα, were significantly elevated in liver cirrhosis. CONCLUSION: β2-integrin expression on leukocytes increases in liver cirrhosis decompensated as the stage of liver failure increases, which is a result of permanent activation of leukocytes circulating through the inflamed liver environment. β2-integrin expression on circulating leukocytes can intensify liver cirrhosis. | Anatol Panasiuk Janusz ■ak Elzbieta Maciorkowska Bozena Panasiuk Danuta Prokopowicz | 2006 | World Journal of Gastroenterology2006，12，38： | 2 |
| 11 | Effect of interferon alpha2b plus ribavirin treatment on selected growth factors in respect to inflammation and fibrosis in chronic hepatitis C显示文摘AIM: Growth factors (GE) that participate in regeneration and apoptosis have an important role in chronic liver diseases. We analyzed serum GF concentration during antiviral treatment and correlated it with morphological liver failure in chronic hepatitis C.METHODS: The levels of GF were determined in sera by ELISA method in 0, 16, 32 and 48 wk of therapy in 40 patients treated with IFNα2b (9 MU sc/wk) and RBV (1.2 g/d) and in 25 healthy subjects. Blind liver biopsies were done before treatment with histological grading and staging examination.RESULTS: The hepatocyte growth factor (HGF) and epidermal growth factor (EGF) were markedly elevated prior the treatment and decreased during the therapy,although they did not reach the normal level. In nonresponding (NR) patients, HGF and EGF were higher than that in responders (R), however differences were not significant. Before the treatment thrombopoietin (TPO)level was significantly lower in R than in NR (P<0.03).Platelet-derived growth factor (PDGF) concentration was lower in chronic hepatitis C than in healthy subjects and decreased during the treatment. A significant positive correlation was observed between inflammatory activity in the liver tissue and the concentration of HGF (in R: r= 0.4,in NR: r= 0.5), TPO (R: r= 0.6), and a significant negative correlation between this activity and EGF (R: r = -0.6)and PDGF (R: r = -0.5), Serum HGF concentration was higher in more advanced fibrosis (R: r = 0.5, P<0.05;NR: r = 0.4, P<0.03).CONCLUSION: The decrease in PDGF can be an effective prognostic marker of the treatment and HCV elimination.Decreasing HGF, EGF, and PDGF can influence the inhibition of inflammatory and fibrotic processes in the liver during the antiviral treatment. | Panasiuk Anatol Flisiak Robert Prokopowicz Danuta | 2005 | World Journal of Gastroenterology2005，11，12： | 1 |

| 13 | Four-year follow up of hepatitis C patients vaccinated against hepatitis B virus显示文摘AIM: Patients with chronic hepatitis C have been recommended to receive vaccinations against hepatitis B. Our study aimed at evaluating the hepatitis B immunogenicity and efficacy against hepatitis B virus infection 4 years after primary immunization series in a group of patients with chronic hepatitis C.METHODS: We recruited 36 out of 48 hepatitis C virus (HCV) infected individuals who were vaccinated against hepatitis B virus (20 μg of recombinant HBsAg at 0-1-6mo schedule) in 1998. Here we measured anti-HBs titers and anti-HBc 4 years after delivery of the third dose of primary immunization series.RESULTS: After 4 years a total of 13/36 (36%) HCV infected patients had seroprotective titers of anti-HBs compared with 9/10 (90%) in the control group, (P<0.05).Similarly the mean concentration of anti-HBs found in hepatitis C patients was significantly lower than that found in healthy subjects (18.3 and 156.0 mIU/mL respectively (P<0.05). None of the HCV infected patients or controls became infected with HBV during the study period as confirmed by anti-HBc negativity.CONCLUSION: We demonstrated that 4 years after HBV immunizations' more than 60% of vaccinated HCV patients did not maintain seroprotective levels of anti-HBs, which might put them at risk of clinically significant breakthrough infections. Further follow-up studies are required to clarify whether memory B and T lymphocytes can provideprotection in chronic hepatitis C patients in the absence or inadequate titers of anti-HBs. | Slawomir Chlabicz Tadeusz Wojciech Lapinski Anna Grzeszczuk Danuta Prokopowicz | 2005 | World Journal of Gastroenterology2005，11，12： | 0 |
| 14 | Expression of bcl-2 protein in chronic hepatitis C:Effect of interferon alpha 2b with ribavirin therapy显示文摘AIM: Mechanisms responsible for persistence of HCV infection and liver damage in chronic hepatitis C are not clear. Apoptosis is an important form of host immune response against viral infections. Anti-apoptotic proteinbcl-2 expression on liver tissue as well as the influence of interferon alpha 2b (IFNα2b) and ribavirin (RBV) were analyzed in patients with chronic hepatitis C. METHODS: In 30 patients with chronic hepatitis C (responders - R and non-responders - NR) treated with IFNα2b+RBV, protein bcl-2 was determined in hepatocytes and in liver associated lymphocytes before and after the treatment.RESULTS: The treatment diminished bcl-2 protein accumulation in liver cells in_patients with hepatitis C (P<0.05). Before and after the therapy, we detected bcl-2 protein in R in 87±15% and 83±20% of hepatocytes andin 28± 18% and 26±10% of liver-associated lymphocytes, respectively. In NR, the values before treatment decreased from 94±32% to 88±21% of hepatocytes and 39±29% to 28±12% of lymphocytes with bcl-2 expression. There was no statistical correlation between bcl-2 expression on liver tissue with inflammatory activity, fibrosis and biochemical parameters before and after the treatment.CONCLUSION: IFNα2b+RBV treatment, by bcl-2 protein expression decrease, enables apoptosis of hepatocytes and associated liver lymphocytes, which in turn eliminate hepatitis C viruses. | Panasiuk Anatol Prokopowicz Danuta Dzieciol Janusz Panasiuk Bozena | 2005 | World Journal of Gastroenterology2005，11，19： | 0 |
