Abstract: المرضى المصابين بفقر دم البحر الابيض المتوسط هم اكثر عرضة للاصابة بالالتهابات الفيروسية المنقولة دمويا. التهاب الكبد الفيروسي نمط جي (HGV)هو فيروس رنوي(RNA) مرتبط بالتهاب الكبد الفيروسي الحاد والمزمن. التهاب الكبد الفيروسي نمط سيHCV) ) والتهاب الكبد الفير | Thalassemia patients are at increased risk of infection with parentally transmitted viral agents. The hepatitis G virus (HGV) is an RNA virus, which is associated with acute or chronic hepatitis. Hepatitis G virus (HGV) and hepatitis C virus (HCV) infections may have a role in complicating the clinical outcome in patients with thalassemia. This study was designed to investigate the prevalence and clinical importance of HGV infection in thalassemia patients with or without hepatitis C virus (HCV) co - infection, furthermore to sequence and analyze phylogentic of HGV clones. One hundred fifty four thalassemia patients (56.5% male, 43.5% female) with a mean age of 22.84±6.06 years were involved in this study that was conducted in the period between Feb. to May, 2014. Anti - HCV antibody was determined by Enzyme Linked Immunosorbent Assay (ELISA) and confirmed by western blot. Then, HCV - RNA was detected in 53.2% of anti - HCV positive thalassemia patients. HGV antibodies were evaluated by ELISA. Also, the HGV viremia was analyzed in patients with thalassemia by reverse transcription polymerase chain reaction (RT - PCR) protocol. Results obtained showed that the anti - E2 - HGV were found in 16 out of 154 (10.4%) thalassemia patients with significant decrease in its prevalence with increasing age, while HGV viremia was diagnosed in 28 out of 154 (18.2%) patients with thalassemia. No association of HGV infection was found with gender, age and frequency of blood transfusion.According to HCV and HGV infection status, thalassemia patients were categorized into four subgroups : subgroup I (HGV infection), subgroup II (HCV infection), subgroup III (co - infection of HCV and HGV), and subgroup IV (thalassemia patients with neither HCV nor HGV infection). Seven point one percent (7.1%) of thalassemia patients were found to be co - infected with HCV and HGV.In all thalassemia subgroups, liver transaminases; alanine transaminase (ALT) and aspartate transaminase (AST), alkaline phosphatase (ALP), and total serum bilirubin (TSB) were determined, in addition to measure serum ferritin levels by VIDAS. HCV infection shows significant increase in ALT level while in HGV is not. Co - infection with HCV and HGV decrease ALT levels when compared with infection with HCV alone, so HGV infection is suggested to have no role in increasing the severity of liver diseases in the thalassemia patients. In HGV infection, there were significant increase in ALP levels and significant decrease in ferritin levels than other subgroups in the study. However, HGV infection shows no significant differences in AST and TSB than other subgroups. The results of genotyping in 12 randomly selected patients showed presence of genotype 2 and genotype 5 with percentage of 91.7% and 8.3% respectively. The diagnosis of prevalence of HGV and HCV in patients with thalassemia in Iraq emphasized the importance of these lymphotropic viral hepatitis infections in pathogenesis and outcome of thalassemia patients.

Abstract: Theoretically , the origin & mode of in - utero transmission of high risk Human PapillomaVirus (HR - HPV) types could be acquired hematogenously, by semen at fertilization or as asending infection in the genital tract. Viral Oncogenes E6 and E7 have ability to altered the Cyclin D1,p21 and p27 protein levels. Worldwide, Human Mammary Tumor Virus(HMTV) infection been described in hormonal responsive tissues.This research work is to study viruses in relaition to endometrial carcinoma in Iraqi patients.Materials and MethodsA retrospective study envolved seventy(70) cases (158 samples) of endometrial and cervical tissues collected from teaching laboratories in Medical City, Al - Yarmok Teaching Hospital and private laboratories related to the period from 2012 to 2014. Sections were made and subjected to chromogenic in - situ hybridization technique to detect the presence of High risk (HR) HPV 16/18 DNA and HMTV integrated DNA (provirus) and immunohistochemical technique to detect the presence of Cyclin D1,P21and P27.Results : The most commonly affected age group was ? 60 year 60.0% in malignant endometrial tumors, 40 - 49 years 36.0% in non - malignant endometrial tumors. Adenocarcinoma was the only histopathological type among endometrial cancer (100%) and the majority have well differentiated grade (90.0% ),and have (70%) T1b/IB stage.Hight risk HPV16/18 expression was detected 33.3% of malignant endometrial tumors, 20% in non - malignant endometrial tumors, andSUMMARY26.7% in control group. The higher rates of expression of HPV in cervical lesions was 40%.Most HPV16/18 infections revealed in both sites (cervix and endomertium) have Punctate DNA pattern.Cyclin D1 expression was mostly in 43.3% of malignant endometrial tumors and 33.3% was in cervical lesions. The significant correlation between Cyclin D1 expression and HR - HPV16/18 infection was reported only in malignant endometrial tumors groups. The highest P21 expression was 40.0% in malignant endometrial tumors and 44.0% in cervical lesions that reveals a significant association between p21 expression and HR - HPV16/18 infection. The highest rates of P27 expression were noticed among non - malignant endometrial tumors 24.0% and 32.0% in cervical lesions.While significant association of P27 expression with HR - HPV16/18 infection was only found in the cervical lesions among malignant endometrial tumors group.The distribution of integrated HMTV genome detected by Chromogenic in - situ hybridaztion (CISH) in the endometrial tissues was 16.7% in malignant endometrial tumor , 8% in non - malignant endometrial tumors, and 13.3% in the control tissues group while in the cervical lesions HMTV was detected in 13.3%. Significant correlations were found between HMTV infection and Cyclin D1 expression in the cervical lesions among malignant endometrial tumors group and p21 expression in the malignant endometrial tumors.ConclusionsHR - HPV16/18 may be associated with initiation of endometrial carcinogenesis events as well as play a role in the progression of such malignant tumors in addition ,these viruses could ascendingly be transmitted from lower part(cervix) to the upper part of the genital tractSUMMARY(endometrium) in some way or other.Cyclin D1 ,P21,and p27 could have sharing in early events of tumorgenesis in endometrial carcinoma and a significant correlations of Cyclin D1 ,p21& p27 expressions with HPV infection was observed among study group.Althought a relating low rates of HMTV infection were detected among different endometrial as well as cervical lesion in this Iraqi study,it might mark or shade alight in the way for further researches in this field to exposure more aspects of this newly studied virus among other hormonal dependent malignancy

Abstract: Blood transfusion is one of the most common routes of viral hepatitis transmission among population. There are several diseases need continuous blood transfusions to manage the patient's condition; one of these diseases is ?thalassemia, so these patients are at increased risk of infection with blood transfusion transmitted agents. SEN - Virus is a DNA virus which is associated with acute post - transfusion hepatitis and the prevalence with the clinical importance and also the genetic characterization are still much unknown in Iraq; therefore, this study was designed to investigate the occurrence and the clinical importance of SEN - virus infection in healthy blood donors and thalassemia patients with or without HCV infection and then the study of the genome sequencing and the phylogenetic analysis of SEN - V clones. One hundred and fifty eight thalassemia patients (57.6% male, 42.4% female), with mean age of 16.8±8.5 year, and one hundred and fifty healthy blood donors with randomly selected persons (58.7%male, 41.3% female), with mean age of 16.7±8.6 year. All these samples involved in this study that were conducted in the period between January to June 2015. SEN - V had been identified by DNA extraction, DNA amplification by nested conventional PCR and then Agarose gel electrophoresis amplified DNA bands detection; while HCV was identified by RNA extraction, RNA reverse transcription into complementary DNA, DNA amplification by nested conventional PCR and then Agarose gel electrophoresis amplified DNA bands detection. Liver transaminases (Aspartate Transaminase and Alanine Transaminase) were determined, in addition of measure of serum ferritin levels by VIDAS. SEN - V was detected in 68 out of 158 (43%) thalassemia patients and 16 out of 150 (10.7%) blood donors. HCV prevalence was (11.4%) in thalassemia patients. There was significant increase observed in the occurrence of SEN - V or HCV infection with age but there was no significant difference observed in the occurrence of both with gender. The most important (hepatotropic) SEN - V genotypes were SEN - V - D and SEN - V - H and there were patients infected with D genotype or H genotype alone, while there were patients co - infected with D and H. According to HCV and SEN - V co - infection status, patients and controls subdivided into six subgroups : subgroup I was thalassemia HCV RNA + and SENV DNA +, subgroup II was thalassemia HCV RNA + and SEN - V - , subgroup III was thalassemia HCV RNA - and SEN - V DNA +, subgroup IV was thalassemia HCV RNA - and SEN - V - , subgroup V was control SEN - V + and finally subgroup VI was control SEN - V - . Statistical analysis revealed that there was significant increase in AST and ALT levels in subgroup I when compared with the other subgroups - that showed the increasing relationship in the case of infection with both viruses - and there were no any significant differences in ferritin levels among these subgroups. Moreover, there were no significant differences between SEN - V - D, SEN - V - H and SEN - V - D and H co - infected samples in AST, ALT and ferritin among thalassemia patients and controls. The results from the study of gene sequencing and phylogenetic analysis of samples of amplified SEN - V - D and samples of amplified SEN - V - H DNA which were selected randomly from blood donors and thalassemia patients infected with D or H genotypes alone or together (co - infection), revealed that the most transmission route of SEN - V D and H was blood transfusion that is because there was (99%) gene similarity between blood donors and thalassemia patients, furthermore SEN - V - D or SEN - V - H sequences of the co - infected persons were the same sequences of D or H genotypes alone and with the observations of similarity with neighboring countries.

Abstract: ما زال الكثيرون لا يعرفون الاهمية السريرية لفيروس تي تي الذى رشح كاحد فايروسات التهاب الكبد انماط A - G)).ان فيروس تي تي يصيب المرضى المعرضين لخطر الحقن ونقل الدم المتكرر، كما في المرضى المصابين بفقر دم البحر الابيض المتوسط(? - Thalassemia major). تمت هذة | Much is still unknown about the clinical significance of TT virus (TTV) that has been reported as a candidate for non A - G hepatitis virus. TTV infects patients at risk for parenteral exposure and chronic blood transfusion, such as those with ? - thalassemia major. This study was designed to investigate the prevalence and clinical importance of TTV infection in thalassemia patients with or without hepatitis C virus (HCV) co - infection, furthermore to sequence and analyse phylogentic of TTV clones.One hundred fifty four thalassemia patients (64.3% male, 35.7% female) with a mean age of 23.8±6.8 years were involved in this study that was conducted in the period between Feb. to Dec. 2013. TTV DNA was detected using Real time PCR. Furthermore, conventional PCR was done for sequencing and phylogenetic analysis using N22 region from open reading frame 1 (ORF1). Anti - HCV antibody was determined by Enzyme Linked Immunosorbent Assay (ELISA) and confirmed by western blot. Then, HCV core antigen was detected in those anti - HCV Abs seropositive samples. Liver transaminases (ALT, AST) were determined, in addition to measure serum ferritin levels by VIDAS ferritin. TTV was detected in 45 of 154 (29.2%) of thalassemia patients with predominance of males than females (64.4% vs. 35.6%). The prevalence rate of anti - HCV Abs were 54.5% with significant increase in females than males (p<0.05).Out of these 84 samples, 59 (70.2%) were positive by HCV core Ag assay and related significantly to frequency of blood transfusion. According to HCV and TTV infection status, patients were categorized into six groups : Anti - HCVAb+ HCV core Ag + TTV+, Anti - HCVAb+ HCV core Ag + TTV - , Anti - HCVAb+ HCV core Ag - TTV+, Anti - HCVAb+ HCV core - TTV - , Anti - HCVAb - TTV+, Anti - HCVAb - TTV - . The increased levels of ALT, AST and ferritin in the HCV and TTV infected group were not significantly different from those in the TTV and HCV negative groups. Co - infection of TTV and HCV were significantly increase ALT levels compared to infection with HCV alone. No association of TTV infection was found with gender, age and frequency of blood transfusion.The results of genotyping in 12 randomly selected patients showed the presence of equal percentage of genotype 1 (G1) and genotype 2 (G2) 50% for each one, with homology between them 79.0%. Other TTV genotypes were not identified in the present study suggesting that G1and G2 are predominant in this area. Mixed infection of the same patient with multiple TTV genotypes was observed. The results concluded that TTV is moderately present in Iraqi thalassemia patients, with G1 and G2 were predominant. Patients co - infected with HCV and TTV had a significantly higher serum ALT level than those without TTV infection, so TTV infection is suggested to have a role in increasing the severity of liver diseases in the thalassemia patients when co - infected with HCV.
