Abstract

Crimean-Congo Hemorrhagic Fever (CCHF) is the highest widespread, tick-borne viral hemorrhagic fever that affect humans. This virus is endemic in many areas in the world, such as Africa, Asia, and Europe. Nowadays, the incidence of CCHF is increasing rapidly in several countries of the middle-east, with several outbreaks and sporadic cases in human of CCHF, that are reported in several countries in this region.Keywords: CCHF, Middle east, IraqCitation: Al-Obaidi AB. Crimean-Congo hemorrhagic fever in the middle east: history and facts. Iraqi JMS. 2018; 16(2): 111-113. doi: 10.22578/IJMS.16.2.1

Abstract

Background:Epstein-Barr virus (EBV) is one of the most common latent viruses inside the humans' B-lymphocytes and it has been documented as a causative agent of many cancers. The virus may be transmitted when infected blood transfused to immunocompromised as well as immunocompetent individuals.Objective:To estimate the prevalence of EBV among apparently healthy blood donors by enzyme-linked immunosorbent assay (ELISA) and by quantitative real time polymerase chain reaction (RT-PCR).Methods:Four hundred fifty (450) blood donors were enrolled in this study. Plasma samples were screened by ELISA technique for detection of EBV viral capsid antigen (VCA-IgG). DNA extracted from 50 representative samples of these 450, and plasma EBV viral load was investigated by RT-PCR.Results:The overall sero-prevalence of EBV IgG was 79.8%, with a significantly higher prevalence among females than males. RT-PCR results were negative for all of the 50 representative samples.Conclusion:The high EBV sero-prevalence rates among Iraqi subjects raise the possibility of increasing the risk of EBV-associated malignant diseases.Keywords:Epstein-Barr virus, seroprevalence, VCA-IgG, real-time PCR, blood donorsCitation:Amjad Q.

Abstract

Background:Viruses are among the most common causes of opportunistic infections after transplantation. The risk for viral infection is a function of the specific virus encountered and the intensity of immune suppression used to prevent graft rejection.Epstein-Barr virus infection has also been implicated as co-factor in acute and chronic rejection syndromes.Objective:Detection of Epstein-Barr viremia in renal transplant recipients.Methods:Fifty seven (57) renal transplant recipients were enrolled in this study. Plasma samples were taken from all renal transplant subjects. Screening of Epstein-Barr virus was first done by serology viamono spot test, then, viral DNA of Epstein-Barr viruswas extracted from 200 µl plasma samples and Epstein-Barr virus DNA was detected and measured by Taqman quantitative real-time PCR.Results:19/57 (33 %) of renal transplant subjects had Epstein-Barr virus viremia and the viral load ranged from 7100 to 16.165 copies/ml. Serology of all RT subjects showed negative heterophil antibody except for one patient had positive hetrophil antibody.Conclusion:The current study showed that Epstein-Barr virus might be considered as an important cause of renal impairment and allograft loss in renaltransplant subjects. And Epstein-Barr virus seems associated with post transplantation renal impairment and/or kidney rejection. Real-time PCR is a very sensitive and specific method for the detection of Epstein-Barr viremia in renal transplant subjects.Key words:Epstein-Barr virus, Renal transplantation, real-time PCR

Abstract

Background:John Cunningham virus (JCV) is one of the important viruses in immunocompromised patients. High JC viruria is seen in kidney allograft recipients; some of them with a polyomavirus associated nephropathy (PVAN) just like BK polyomavirus but to a lesser extent.Objective:To detect JCV viruria in a sample of Iraqi renal transplant recipients, and its association with renal function.Methods:A prospective study enrolled 71 renal transplant recipients (RTR) and 20 normal donors (ND) as controls. Urine samples were collected from all RTR and ND. Viral DNA was extracted from 1 ml urine samples, and then, JC virus DNA was detected and measured by Taqman quantitative real-time PCR.Results:Out of 71 RTRs, 31 (43.66%), and 2 out of the 20 (10%) controls had positive JC viruria. The mean JCV viruria was 6.8 x104, and 1.04x103 copies/ml for RTRs and controls respectively.Conclusion:There is a relatively high prevalence of JCV viruria in Iraqi RTR patients.Keywords:JC virus, renal transplantation, urine, real-time PCR.

Abstract

Background:BK polyomavirus is one of the common post-transplant viral infections, affecting ∼15% of renal transplantation recipients (RTR), leading to graft loss in more than half of cases.Objectives:Study the rate of detection of BK virus (BKV) in RTRs in Pap-stained urine cytology specimens.Methods:A single center study, urine samples were collected from 99 RTR patients, with 15 Living Donors (LD) and 15 patients with chronic kidney disease (CKD) were taken as controls. And urine cytology smears were Pap stained for detection of decoy cells (DCs).Results:Out of the 99 RTRs, 27 (27.3%) patients were decoy positive, 8 out of these 27 patients had uncommon DCs, and 5 out of these 27 cytology positive patients (18.5%) had biopsy proven BKV nephropathy (BKVN).Conclusion:This study suggests that the finding of BKVN in 18.5% of the DC positive patients stresses the importance of screening for BK polyomavirus with Pap-stained urinary cytology in RTR.Key wards:BK polyomavirus, renal transplantation, decoy cells
