Varicella is clearly less dangerous for immunized mothers. The aim of this study was to determine the prevalence of VZV antibody among women before marriage.  Materials and Methods: This cross-sectional study was conducted on 300 women of child-bearing age who referred to Yazd clinic for premarital screening. The enzyme-linked immunosorbent assay (ELISA) technique was performed to detect antibodies against VZV. Demographic characteristics of each participant, including age, educational level, place of residence, family and self-reported history of chickenpox were collected by a questionnaire. Results: Mean age of women under study was 23±5.4 years that 223 participants (73.7%) were seropositive, and 77 cases (25.7%) were seronegative for anti-VZV antibody, while 2 (0.6%) subjects had an equivocal result. A higher immunity ratio (86.4%) was found among older women (33-44 years). Data showed no significant correlation between immunity to VZV and age, educational level, place of residence. A statistically significant association was found between the family history, self-reported history of chickenpox and immunity to VZV. The positive and negative predictive values for self-reported history of chicken pox were 97.1% and 81.1%, respectively. Conclusions: A significant number of women before marriage had no immunity to VZV.  They are in risk of getting varicella, which can cause serious complications in mother and fetus. It, therefore, seems necessary to screen women of child-bearing age for anti-VZV antibody. In addition, vaccination against VZV in Iranian women before marriage can be a good recommendation.}, Keywords = {Antibody, Chickenpox, seroprevalence, Varicella-Zoster Virus}, volume = {10}, Number = {2}, pages = {1-6}, publisher = {Iranian Society for Virology}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.21859/isv.10.2.3.1}, url = {http://journal.isv.org.ir/article-1-269-en.html}, eprint = {http://journal.isv.org.ir/article-1-269-en.pdf}, journal = {Iranian Journal of Virology}, issn = {1735-5680}, eissn = {2588-5030}, year = {2016} } @article{ author = {Fazel, Hadi and Shadmand, Enayatollah and Baharlou, Rasoul and Shokouh, Mohammad Reza and Hashemi, Mohammad Ali and Farahmand, Mohammad and AhmadiVasmehjani, Abbas and sadeghi, kaveh}, title = {Sero-Epidemiology of Hepatitis E Infections in patients with chronic Hepatitis C virus infection in Jahrom, Southern Iran}, abstract ={Background and Aims: Co-infection of hepatitis E virus (HEV) in chronic hepatitis C virus (HCV) infected patients can develop and increase liver disease and hepatic complications in the world. The purpose of this study was to assess the prevalence of HEV infection in patients suffering from chronic HCV infection. Materials and Methods: Cross-sectional study testing anti-HEV antibodies in serum samples belonged to 53 chronic HCV infected patients were evaluated. Demographic and clinical data such as liver function tests and enzymes level were prospectively collected on each patient with chronic HCV infection. Results: There were 5 HEV infected patients IgG positive among the 53 chronic HCV infected patients. These patients had an alanine aminotransferase (ALT) level twice the upper level about of the 48 HEV negative patients (p<0.0001).

Although HEV is believed to be transmitted by fecal-oral routes between humans in low sanitary conditions, but evidence of transmission have been reported in hemodialysis (HD) patients. Materials and Methods: Aim of present study was to determine the prevalence of anti-HEV antibody among HD patients in Gorgan, north of Iran. In this cross-sectional study, totally 300 HD patients from May to December 2014 were tested for detection of anti-HEV IgG and IgM by commercial HEV enzyme-linked immunosorbent assay (ELISA) kit. Demographic variables were collected in pre-designed questionnaires. Results: Out of 300 individuals, 148 (49.3%) were male and 152 (50.7%) were female. The overall anti-HEV IgG seroprevalence rate was 4%. Result showed significant association between anti-HEV IgG and duration of dialysis (p = 0.03), but there were no significant differences between the subjects grouped according to gender, Ethnicity, dialysis per week and age. No anti-HEV IgM were detected in patients. Conclusions: Since our finding showed statically significant relationship between duration of hemodialysis and anti-HEV.

Materials and Methods: During 1394 -1395, 10 blood samples taken from HTLV-1 virus infected individuals. Samples went through polymerase chain reaction (PCR) process.The obtained products were sequenced and phylogenetic analysis were done. The second and third structures of these sequences were obtained by using a specialized websites. Results: The Iranian samples were completely exposed in to the cluster of Cosmopolitan subtype. The result of first structure alignment of protease protein in different subtypes of the virus, suggested some differences in the gene of interest. The conversion of the first structure to second and third structures and respectively pairwise and multiple alignment showed no significant difference in the protease protein conformation. Conclusions: The comparison of HTLV-1 virus protease protein from Iran and other sequences in the world which were obtained from GenBank shows no significant dissimilarity. This dissimilarity help to design the production of the drug. Therefore, future studies can be targeting a part of the protein and generalize the treatment outcomes to all subtypes circulating.

The main etiology of this cancer in developing and third world countries is due to the infection with hepatitis B and C viruses. Hepatitis B and C viruses (HCV) would both cause liver cancer but the incidence of the disease in relation to the age and gender has not been determined. The present study was conducted to evaluate the relation between some demographic characteristics with rs1053004 polymorphism in STAT3 gene among patients with liver cancer following chronic hepatitis B infection and its comparison with healthy subjects. Materials and Methods: In this study, 33 tissue samples of liver cancer from pationts with HBV infection, 50 blood samples from patients with chronic hepatitis B and 50 blood samples from healthy subjects, as the control group, were obtained to determine rs1053004 polymorphism in STAT3 gene (signal transducer factor and activator of transcription in the nucleus) using Real Time PCR method. Results: In the present study 133 subject were evaluated and from them, 50 (37.6%) were healthy and 50 of the participants (37.6%) had chronic hepatitis B and 33 (24.8%) had HCC. 69.9% of the participants (93 participants) were male and 30.1% (40 participants) were female. According to the results, the gender of the participants in the studied groups had no significant relation with their SNPrs1053004 polymorphism. But the relation between gender and liver cancer was statistically significant (p < 0001); indicating that the prevalence of liver cancer was higher among men than women. The average age of the healthy group was 35.86 years, of the chronic hepatitis B group was 40.4 years and of the HCC group was 53.78 years. Based on the results, the difference in age groups of chronic hepatitis B group and HCC pationts was statistically significant as compared with the control group (p < 0.001). Conclusions: Results of the present study showed no significant relation between the presence of rs1053004 polymorphism in STAT3 gene (signal transducer factor and activator of transcription in the nucleus) and gender of the participants but the difference between the ages of the healthy group, chronic hepatitis B group and HCC group was statistically significant.
