| Determination of the Relationship of Serum Hyaluronic Acid Levels to the Degree of Liver Fibrosis in Biopsies of Patients with Chronic Viral Hepatitis B & C
Moradi Moghaddam F ، Arrbabi H ، Khajedaloei M Page 168 (انگليسي)
 Abstract مشاهده متن [PDF 377KB] | | Background and Aims: Determining the stage of liver fibrosis and the grade of necroinflammation is important in predicting the prognosis and treatment response of patients with chronic viral hepatitis. Liver biopsy is associated with several technical problems and complications; therefore، its repetitive performance as a procedure in evaluating treatment response and in following up patients is not recommended. This study was performed to determine the correlation of serum hyaluronic acid (HA) levels with the stage and grade of histopathologic liver changes in patients with chronic hepatitis B and C.
Methods: This analytical cross-sectional study was performed on 69 patients with chronic hepatitis B or C in Mashhad، Iran، who were referred to our clinic and underwent liver biopsy and blood sampling simultaneously in 2006-2007. None of the patients were on medication that would affect the serum levels of (HA) and patients with signs of arthropathy were excluded from the study.
Results: Out of the 69 patients in this study، 48 (69.6%) were male and 21 (30.4%) were female. The causative virus in 29 patients (42%) was hepatitis C and in the rest (n = 40، 58%) hepatitis B. The severity of liver fibrosis (stage) had a direct correlation (r = 0.25، P = 0.042) with the levels of (HA) and an inverse correlation with the platelet level (r = 0.37، P = 0.002). The degree of liver necroinflammation (grade) did not have a significant correlation with the levels of (HA) and alanine transaminase (r = -0.01، P = 0.9; r = 0.21، P = 0.09 respectively); instead، there was an inverse correlation with platelet levels (r = 0.36، P = 0.003).
Conclusions: Our study results correspond with those of other international studies; thus suggesting that the (HA) serum level is a useful marker in determining the severity of fibrosis in patients with chronic viral hepatitis. To form a definite conclusion، further studies on large groups should be performed.

| Are Hepatitis B Virus and Celiac Disease Linked?
Leonardi S ، Rosa ML Page 173 (انگليسي)
Abstract مشاهده متن [PDF 367KB] | | Background and Aims: It has been hypothesized that nonintestinal inflammatory diseases such as hepatitis B virus (HBV) and hepatitis C virus (HCV) may trigger immunologic gluten intolerance in susceptible people. This hypothesis suggests a possible epidemiological link between these two diseases، although this assumption is still a matter of debate.
Methods: We conducted a retrospective study to assess the prevalence of celiac disease in HBV carrier patients who had been infected in childhood.
Results: None of the HBV carrier patients had immunoglobulin A antiendomysium and immunoglobulin A anti-tissue transglutaminase، but 6 patients and 1 recovered subject had immunoglobulin A antigliadin and/or immunoglobulin G antigliadin. Moreover، no patient treated with interferon therapy showed any serological marker of celiac disease.
Conclusions: Due to the small sample size، we cannot claim that there is no association between celiac disease (CD) and HBV، although in our study we did not find any CD patients. A sample size that is more representative of the prevalence of CD in Italy would better support the establishment of any possible connection between CD and HBV.

| Knowledge، Attitudes and Practice of Iranian Medical Specialists regarding Hepatitis B and C
Kabir A، Tabatabaei SV، Khaleghi S، Agah S، Faghihi Kashani AH، Moghimi M، Habibi Kerahroodi F، Alavian SH، Alavian SM Page 176 (انگليسي)
Abstract مشاهده متن [PDF 426KB] | | Background and Aims: Health care workers (HCWs) are at risk of contracting and spreading hepatitis B virus (HBV) and hepatitis C virus (HCV) to others. The aim of this study was to evaluate knowledge، attitudes and behavior of physicians concerning HBV and HCV.
Methods: A 29-item questionnaire (reliability coefficient = 0.7) was distributed at two national/regional congresses and two university hospitals in Iran. Five medical groups (dentists، general practitioners، paraclinicians، surgeons and internists) received 450 questionnaires in 2009، of which 369 questionnaires (82%) were filled out.
Results: Knowledge about routes of transmission of HBV and HCV، prevalence rate and seroconversion rates secondary to a needlestick injury was moderate to low. Concern about being infected with HBV and HCV was 69.4±2.1 and 76.3±2 (out of 100)، respectively. Complete HBV vaccination was done on 88.1% of the participants. Sixty percent had checked their hepatitis B surface antibody (anti-HBs)، and 83.8% were positive. Only 24% of the surgeons often used double gloves and 28% had reported a needlestick. There was no significant correlation between the different specialties and: concern about HBV and HCV; the underreporting of needlestick injuries; and correct knowledge of post-needlestick HBV infection.
Conclusions: Although our participants were afraid of acquiring HBV and HCV، knowledge about routes of transmission، prevalence، protection and post-exposure seroconversion rates was unsatisfactory. By making physicians aware of possible post-exposure prophylaxis، the underreporting of needlestick injuries could be eliminated. Continuous training about HBV and HCV transmission routes، seroconversion rates، protection، as well as hepatitis B vaccination and checking the anti-HBs level، is a matter of necessity.

| Entecavir Therapy in Turkish Adult Patients with Chronic Hepatitis B: One-Year Results from Izmir Province, Turkey
Kose S ، Ulusoy MT ، Akkoclu G ، Gozaydin A Page 183 (انگليسي)
Abstract مشاهده متن [PDF 376KB] | | Background and Aims: In the present study، we aimed to present the initial results of chronic hepatitis B patients who received entecavir (ETV) therapy in our hospital in Izmir، Turkey.
Methods: A total of 52 patients were enrolled in the study. ETV was given in a dosage of 0.5 mg/day and 1 mg/day to 50 patients without Lamivudine/Adefovir (LAM/ADV) resistance and to 2 patients with LAM resistance، respectively. ETV was given in a dose of 0.5 mg/day every three days to one patient with a renal transplant. The treatment duration was 48 weeks.
Results: Out of a total of 52 patients، 23 (44.23%) were hepatitis B e antigen (HBeAg)-positive، and 29 (55.77%) of them were HBeAg-negative. In 29 HBeAg-negative patients، early biochemical and virological responses were 82.6% and 100%، respectively. These responses were 97% and 79.3% in the 12th month. In HBeAg-positive patients، early biochemical and virological responses were found to be 78.3% and 82.6%، respectively. They were 100% and 52.2% in the 12th month. HBeAg seroconversion developed in 4.5% of HBeAg-positive patients.
Conclusions: According to our one-year ETV treatment results، both HBeAg-negative and -positive patients had high biochemical and virological response rates. Their HBeAg seroconversion rate was 4.5%. In conclusion، more studies of longer duration are needed to understand the required duration of treatment، to assess its long-term effectiveness، and to check the resistance and side effects of ETV. There is also a need to have late-phase results after treatment.

| Hepatitis B and C among Patients Infected with Human Immunodeficiency Virus in Isfahan, Iran: Seroprevalence and Associated Factors
Ataei B ، Tayeri K ، Kassaian N ، Farajzadegan Z ، Babak A Page 188 (انگليسي)
Abstract مشاهده متن [PDF 381KB] | | Background and Aims: Patients with human immunodeficiency virus (HIV) are also likely to be at risk for other infectious pathogens including hepatitis B (HBV) and C (HCV) viruses، which complicate the clinical course، management، and therapy. The literature on the prevalence of HBV/HCV coinfection with HIV in Iran is sparse. Hence this study was conducted to investigate this coinfection pattern and its risk factors in Isfahan، Iran.
Methods: All of the HIV-infected patients attending clinics for acquired immune deficiency syndrome (AIDS) research and education in Isfahan province during the period of May 1998 through April 2007 were included in this cross-sectional study. After giving their informed consent، the patients were screened for hepatitis B surface antigen (HBsAg) and antibodies to hepatitis C virus (anti-HCV)، and anti-HCV-positive cases were confirmed with the RIBA test. The demographic data and information about risk behaviors were collected as well. Multivariate logistic regression was used to identify independent risk factors for HBV and HCV.
Results: The subjects included 130 patients (128 males and 2 females) with a mean age of 50.23 ± 8.81 years. Most of the subjects were unemployed (61.5%) and single (56.2%). A history of imprisonment، ، intravenous drug abuse، and high-risk sexual activity were reported by 83.7%، 83.5%، and 48% of the subjects، respectively. Coinfection with hepatitis viruses was observed in 78.5% of the subjects. Low levels of education، a history of imprisonment، and youth were the main risk factors for HCV/HIV coinfection (OR = 196، 114، and 0.9 respectively).
Conclusions: Our study showed that there is a high prevalence rate of HCV/HIV coinfection in Isfahan، Iran، with the major risk factor being a history of imprisonment.

| European vs. Egyptian HCV-4 Patients with Elevated Baseline HCV-RNA, Treated with PEG-IFN-α2a and Ribavirin: The Role of Rapid and Early Virologic Response
Dimitroulopoulos D ، Elefsiniotis I ، Pavlidis C ، Xinopoulos D ، Tsamakidis K ، Patsavela S ، Kypreos D ، Ferderigou A ، Korkolis D ، Koutsounas S ، Saroglou G ، Paraskevas E Page 193 (انگليسي)
Abstract مشاهده متن [PDF 827KB] | | Background and Aims: Despite the recent spread of hepatitis C virus genotype 4 (HCV-4) into European countries، very little is known about the influence of ethnicity on treatment outcomes in patients with HCV-4. The aim of this study was to compare the virologic response (VR) rates of: rapid virologic response (RVR)، early virologic response (EVR)، VR at 24 weeks of treatment، at end of treatment (EoT)، and sustained virologic response (SVR) of European and Egyptian HCV-4 patients.
Methods: Sixty (30 Europeans – Group A; and 30 Egyptians – Group B) chronic HCV-4 subtype A adult patients with elevated baseline viral load (>800 000 IU/m L) were treated for a fixed period of 48 weeks with pegylated interferon α2a (PEG-IFN- α2a) and ribavirin. During the study، HCV-RNA levels were measured at weeks 4،12،24،48 and 72.
Results: Baseline characteristics، including liver histology، were similar in the two groups. RVR، EVR and HCV-RNA at week 24 in Groups A and B were (RVR 26.7% vs. 30.0%) (EVR 23.3% vs. 16.7%) (in week 24 13.3% vs. 16.7%). Overall SVR rates were 36.7% (11/30) for Group A and 26.7% (8/30) for Group B (P = 0.59). For group B، RVR was the weakest indicator for SVR as compared with RVR of group A، where RVR was the best SVR indicator.
Conclusions: The overall response to treatment was similar، but ethnic origin or previous history and treatment of schistosomiasis may influence intermediate response rates of chronic HCV-4a infected patients with elevated baseline HCV-RNA.

| Occult Hepatitis B Infection in Chronic Hemodialysis Patients: Current Concepts and Strategy
Hollinger FB ، Habibollahi P ، Daneshmand A ، Alavian SM Page 199 (انگليسي)
Abstract مشاهده متن [PDF 442KB] | | The prevalence of end-stage renal disease has increased dramatically in developing countries، and this has been accompanied by the widespread utilization of chronic hemodialysis in its management prior to kidney transplantation. Within this group، the interjection of hepatitis B virus (HBV) infection represents a significant co-morbidity event that has led to several outbreaks of hepatitis B. Occult hepatitis B (OHB) is a variant of conventional hepatitis B that is manifested by the presence of HBV DNA in blood and/or tissue in the absence of hepatitis B surface antigen (HBsAg). It is postulated that its impact on chronic hemodialysis patients also might be of importance. Unfortunately، there are only a limited number of published studies on this topic and، in most cases، only prevalence data are reported without descriptions of histopathology or outcome measurements. In this paper، we have reviewed this information. Based on the scarcity of available data، HBV DNA assessment with highly sensitive assays might be informative in this target population، especially among those hemodialysis patients who present with isolated antibodies to the hepatitis B core antigen (anti-HBc) or who are hepatitis C virus (HCV) RNA positive، since HCV coinfection appears to worsen the outcome. Clearly، more precise studies need to be performed to answer questions concerning the impact of OHB in chronic hemodialysis patients.

Umar M ، Bushra H ، Ahmad M ، Khurram M ، Usman S ، Arif M ، Adam T ، Minhas Z ، Arif A ، Naeem A ، Ejaz K ، Butt Z ، Bilal M Page 205 (انگليسي)
Abstract مشاهده متن [PDF 871KB] | | Hepatitis C virus (HCV) infection is increasingly recognized as a major health care problem، and is found frequently in Pakistani settings. In this article we reviewed published and unpublished data related to the seroepidemiology of HCV infection in Pakistan. For this article، data from 132 published studies and three unpublished data sets published/ presented between the period 1992-2008 were utilized. Data of 1،183،329 individuals were gathered. Blood donors (982،481) and the general population (178،322) constituted the majority of these subjects. The frequency of HCV infection in blood donors and in the general population was 3.0 % (95% CI: 3.0- 3.1) and 4.7 (95% CI: 4.6 -4.8)، respectively. The frequency among 6،148 pregnant females was 7.3% (95% CI = 6.7 – 8.0). The frequency in healthy children ranged from 0.4 to 4.1% (95% CI = 1.4 – 2.3). Pakistani HCV serofrequency figures are significantly higher (P < 0.0001) compared to those of the corresponding populations in surrounding countries like India، Nepal، Myanmar، Iran and Afghanistan.

| Amazing Results with Hydroxyurea Therapy in Chronic Hepatitis B: A Preliminary Report
Kashani HH ، Vossoughi A ، Adibi P ، Alavian SM Page 215 (انگليسي)
Abstract مشاهده متن [PDF 386KB] | | Background and Aims: To introduce the possible role of hydroxyurea (HU)، a well-characterized antineoplastic drug with established antiviral effects، in the treatment of chronic hepatitis B.
Methods: Four antiretroviral-naïve patients with chronic hepatitis B were enrolled in this limited pilot trial، and given 1000 mg/day of hydroxyurea for 4 weeks; then، the administration of the drug was suspended for 4 weeks. A clinical study and laboratory safety assessments and measurements of viral load were made at baseline، after drug therapy، and after one month suspension of the treatment.
Results: All 4 patients showed a significant decrease in viral load after 4 weeks of hydroxyurea therapy and the viral load of 2 patients increased again after a 4-week suspension of hydroxyurea.
Conclusions: Our data demonstrate that the old low-cost antineoplastic drug، hydroxyurea، efficiently blocks hepatitis B virus (HBV) replication. We suggest that HU will play an important role in the treatment of chronic hepatitis in the fore- seeable future. Further studies including those that evaluate optimal dosing in long-term use will continue to define the role of HU in the treatment of HBV infection alone or in combination with other antiviral drugs.

Asadi Noghabi AA ، Zandi M ، Mehran A ، Alavian SM ، Hasanpour Dehkordi A Page 218 (انگليسي)
Abstract مشاهده متن [PDF 362KB] | | Background and Aims: The main purpose of treating and caring for patients with chronic viral hepatitis is to promote life satisfaction and a feeling of well-being in patients suffering from this disease. The aim of this study was to evaluate the effect of education on quality of life in patients with chronic hepatitis who were treated with Interferon alpha.
Methods: This quasi-experimental study was conducted on 60 patients with viral hepatitis. The intervention included teaching them the method of self injection of Interferon alpha 2 b، giving them educational pamphlets and then following their continuing treatment with interferon. Patients were randomly assigned to two 30-patient groups. The data- gathering tool was a demographic characteristics questionnaire and the Quality of Life Questionnaire for Patients with Chronic Liver Disease (CLDQ). The educational program was done in four 45- minute sessions for the case group and their relatives. The follow-up period was 12 weeks. Quality of life in patients with chronic hepatitis was measured before initiating interferon therapy، and after the educational period. Quality of life in the two groups was compared.
Results: The total quality of life score in the two groups before therapy did not show any significant difference (P = 0.351); while 12 weeks after education there was a significant difference between the two groups (P < 0.001) in three items including abdominal symptoms (P = 0.01)، worry (P < 0.001) and emotional factors (P < 0.001). The other three items did not show a significant difference between the two groups. The total quality of life score in the case group was significantly different before and after education (P < 0.001)، and improved after education. The total quality of life score in the control group did not differ significantly after 12 weeks (P = 0.143).
Conclusions: Planning short and simple educational programs has a significant effect on the patient’s control of his/her disease and its side effects; and can improve quality of life، life satisfaction، and mechanisms of coping with treatment in patients with viral hepatitis.
