Comparison of adenovirus viruria in bone marrow transplant patients before and after transplantation
Abstract: (13671 Views)
Baekgrouund & purpose: In recent years, the role of adenoviruses in infection and disease in recipients of bone marrow transplantation (BMT) has been studied. It suppose that adenoviral infections are prevalant in these patients Due to using medicines for preventing transplant rejection. This study was performed to compare the incidence of adenoviruses in urine samples taken before and after BMT from individuals undergoing BMT. In addition, The correlation between age, sex, etiology and kind of transplantation and adenovirus infection was studied.
Materials and Methods: From 11 November 2002 to 12 June 2003, 91 patients received BMT in Hematology, Oncology and Bone Marrow Transplantation center of Tehran University of Medical Sciences. From 72 patients, 2 urine samples were taken before and 4 weeks after transplantation The DNA samples were examined by PCR using primers that detect 134 bp sequence in Hexon gene shared in human adenovirus DNA was extracted using Phenol-Chloroform method and concentrated by sodium acetate and ethanol.In Faculty of Medicine, Shahed University.
Results: Adenovirus DNA was found in 39 patients (54.2%) before transplantation and in 37 patients (51.4%) after that. Both before and after BMT samples were negative for adenoviruses in 21 patients and positive in 25 patients. In 14 patients only before BMT and in 12 patients only after BMT urine samples were positive. No statistical difference between before and after BMT viruria was shown by McNemar’s test. Also, no statistical difference was shown between mean age of infected and non-infected patients by t-test. In spite of higher frequency of males, malignant and allogeneic transplant among studied patients, there was no statistical difference between two mentioned patients (P>0.05).
Conclusion: In the present study, increase of prevalence of viruria in patients after bone marrow transplantation was not seen. In adition, there was no correlation between patients with various age, sex and etiology and kind of transplantation. Further studies about prevalence of adenovirus in patients undergoing bone marrow transplantation. recommended for prevention of mortality by better take care of patients and treatment by antiviral drugs or decrease in suppressive drugs.
