Abstract
JC virus (JCV) causes progressive multifocal leukoencephalopathy in immunocompromised patients. The prevalence and genotype patterns of JCV vary between different geographical regions. This study was done to investigate the prevalence and genotype distribution of JCV in patients with hematological malignancies in Vietnam. A total of 48 urine samples were collected from patients with hematological malignancies. DNA was extracted and detection of JCV was by nested-polymerase chain reaction. Sequence analysis was obtained and a phylogenetic tree was constructed for genotyping of JCV. Twenty-seven (56.25%) urine samples tested positive for JCV. JCV genotype 7 was only observed in this study. Subtype analysis showed that JCV subtype 7A was the most commonly prevalent, followed by 7B1 and 7C1. Other subtypes were not detected in this population. There were no significant differences associated with age, gender, and biochemical parameters between patients with JCV and without JCV excretion in urine. The present study showed a high prevalence of JCV in the urine of patients with hematologic malignancies. The most common genotype found in this population was JCV subtype 7A.

Abstract
JC polyomavirus (JCPyV) is the causative agent for progressive multifocal leukoencephalopathy (PML) in immunocompromised patients. More than 40% of healthy population excretes JCPyV particles in their urine. As JCPyV is ubiquitous in human, the definition of genotype distribution can help trace population migration. In this study, to define the frequency of JCPyV in southwest of Iran, urine samples of 161 volunteers including 80 healthy individuals and 81 HIV-infected patients were collected. PCR assays and sequence analysis were performed using JCPyV-specific primers designed against VP1 coding region. JCPyV DNA was detected in 65 out of 81 urine samples (80.2%) of HIV-infected, and in 43 out of 80 urine samples (53.8%) of healthy individuals (P = 0.001). The shedding of JCPyV among HIV-infected patients revealed an age-related pattern while such relationship was not observed in healthy individuals group. The most common genotype found in this region was genotype 3A (80.8%), followed by genotype 2D (11.5%), 4 (3.8%), and 7 (3.8%). The frequency of JCPyV in the urine of HIV-infected patients was found significantly higher than in the healthy individuals (P = 0.001).

Abstract
Abstract
Polyomaviruses are common viruses that induce various infections in many mammalian species, including humans. The best-known viruses of this kind are BKV and JCV. The aim of the study was to analyze the incidence of infection caused by JCV in a group of patients after kidney or bone marrow transplant, and to analyze JCV genetic diversity in post-transplantation recipients. The study group included 81 patients after kidney transplantation treated in the Independent Public Teaching Hospital No 4 in Lublin and a group of 24 patients after marrow transplantation from the Children's Clinical Hospital of Lublin. The research material included 105 DNA probes from urine samples that were tested via the PCR method for the presence of JCV genetic material. Amplification products were separated in agarose gel, positive PCR products were subjected to purification and the pure product was sent to sequencing. Pearson's chi-square test was used to investigate the relationship between the prevalence of JCV viruria and study group and gender. Statistical significance was defined as p < 0.05. A JCV positive result was discovered in 27.6% of all samples. In the group of adults, 34.6% were positive, while in children, this was 3.4%. Among all patients, only 8 women were infected with the JC virus, while 21 men were. We saw that the incidence of infection caused by the JC virus increases with age. Moreover, JCV DNA is more frequently isolated from men than from women. JCV infections are also a more common cause of infections in patients after renal transplantation than in bone marrow transplant patients

Abstract
In immunocompromised individuals, especially in patients with T cell immunodeficiency, reactivation of JCPyV can cause serious life-threatening diseases. Nowadays, HIV infection is one of the most important factor for reactivation of JCPyV and the development of of the progressive multifocal leukoencephalopathy (PML). Mutations in the outer loops of the VP1 region can lead to the selection of the viral variants with changed tropism and increased pathological potential. The aims of this study were to determine sequence variation and amino acid changes within VP1 loops and the structure of non-coding control region (NCCR) of urinary excreted JCPyV isolates among HIV-infected patients and healthy donors. Single urine samples from 114 HIV-infected patients and 120 healthy donors were collected. PCR was performed for amplification of VP1 and NCCR. Amplified fragments were directly sequenced and analyzed by using bioinformatics tools. Nucleotide substitutions were detected within DE and EF loops and in the β-sheets of both studied groups. In HIV-infected patients group, 70% of mutations were detected within receptor domains. Among healthy donors, one mutation was identified within β-sheets while the remaining were located within receptor domains. The most prevalent mutation was L157V in both groups. Analysis of NCCR revealed that all isolates had archetype structure with some minor changes. Since single point mutations at specific place within outer loop of VP1 region can cause formation of variants with changed receptor specificity, identification of these mutations in HIV-infected patients can help to single out those with higher risk for development of polyomavirus-associated diseases.

Abstract
John Cunningham virus (JCV) reactivation, occurring mainly in immunocompromised patients, leads to progressive multifocal leukoencephalopathy, an uncommon but lethal disease. JCV reactivation after T-cell replete haploidentical stem cell transplantation, in the pre-cyclophosphamide era, is poorly represented in the literature. We therefore describe two cases of acute myeloid leukemia who developed JCV reactivation after receiving cyclophosphamide and rituximab post haploidentical stem cell transplantation, and review the literature, aiming to a better understanding of the disease course and its risk factors.

Abstract
In healthy individuals John Cunningham virus is latent without any clinical signs, but in the cases of the use of immunosuppressive drugs in graft recipients, autoimmune diseases and also increasing of age, that the immune system is suppressed it may cause disease in reactivation. Progressive multifocal leukoencephalopathy (PML) is the well-known disease caused by the virus. It has also been associated with nephropathy and tumorogensis. At present, based on vp1 capsid gene 7 genotypes have been detected. Genetic variations of JC virus in different geographical areas and the presence of different subtypes is a useful tool for reconstructing of the genetic information of JC virus and understanding of its evolution. The aim of this study was to investigate different genotypes of the JC virus in the urine of 100 kidney transplant recipients, 43 rheumatoid arthritis patients, and 100 healthy individuals as control group in Isfahan. DNA was extracted by phenol-chloroform method and subjected to a nested PCR using specific primer for vp1 capsid gene designed by Oligo 7 software. Fisher's exact test was used for statistical analyses. Using MEGA 6 software the sequences were aligned using Clustal W tool and phylogenetic trees were constructed by neighbor joining method. Thirty-one positive samples were sequenced. Genotypes 1, 3, and 4 of the virus were detected for the first time in Iran. For the first time genotype 3 was reported as the dominant genotype in Iran. For the first time in the world, genotype 4 was detected in rheumatoid arthritis patients. J. Med. Virol. 89:337-344, 2017. © 2016 Wiley Periodicals, Inc.

Abstract
The aim of this study was to investigate and compare the frequency of BKV, JCV, WUV, and KIV in the saliva of healthy individuals. Samples were analyzed for the presence of polyomaviruses (BKV, JCV, WUV, and KIV) DNA by real-time PCR. Of the 291 samples tested, 71 (24.3%) were positive for at least one of the screened polyomaviruses. Specifically, 12.7% (37/291) were positive for WUV, 7.2% (21/291) positive for BKV, 2.4% (7/291) positive for KIV, and 0.3% (1/291) positive for JCV. BKV and WUV co-infections were detected in 1.7% (5/291) of individuals. No other co-infection combinations were found. The mean number of DNA copies was high, particularly for WUV and BKV, indicating active replication of these viruses. Polyomavirus detection was higher among individuals 15-19 years of age (46.0%; 23/50) and ≥50 years of age (33.3%; 9/27). However, the detection rate in the first group was almost 1.7× greater than the latter. WUV infections were more frequent in individuals between the ages of 15 and 19 years and the incidence decreased with age. By contrast, BKV excretion peaked and persisted during the third decade of life and KIV infections were detected more commonly in subjects ≥50 years old. These findings reinforced the previous hypotheses that saliva may be a route for BKV transmission, and that the oral cavity could be a site of virus replication. These data also demonstrated that JCV, WUV, and KIV may be transmitted in a similar fashion.

Abstract
John Cunningham virus (JCV) encodes an oncogenic T-antigen, which is capable of interacting with key growth regulatory pathways. JCV definite role as causal agent of human cancer, still awaits final confirmation. The present study was conducted to assess the possible role of JCV in Egyptian colorectal carcinoma (CRC) and correlate the expression with the clinicopathological features and survival. JCV in situ hybridization (ISH) signals and large T antigen immunoreactivity were examined in 87 colonic specimens. Positive glandular JCV ISH signals were detected in 20%, 25% and 40% of normal, adenoma and CRC cases respectively. Stromal JCV ISH signals were identified in 26% of CRC cases and 5% of adenoma however, normal mucosa did not show stromal positivity with significant difference (p = 0.03). Glandular JCV expression was significantly associated with high grade (p = 0.03), high mitotic index (p=0.02) and low apoptotic index (p = 0.00). Positive stromal signals were significantly associated with low apoptosis (p = 0.00). No positive nuclear immunostaining of JCV large T antigen was detected in all specimens. JCV stromal expression was the 2nd most powerful indicator of short survival and bad prognosis (p = 0.03) in CRC patients. JCV might play an etiological role in CRC tumorogenesis and short survival in Egyptian CRC patients.

Abstract
JC virus (JCV) is ubiquitous in the human population, infecting children asymptomatically. After primary infection, JCV persists in the host throughout life and is often excreted in the urine. Two hundred thirty-four urine samples and 78 serum samples, collected from 171 healthy individuals and 63 patients infected with HIV, were used to characterize JCV infection in a Portuguese population. Using PCR, JCV DNA was detected in 38% of the urine samples. A significant difference in the excretion rate was observed between patients infected with HIV (51%) and healthy individuals (33%). The frequency of JCV viruria increased with age in healthy individuals, but not in patients infected with HIV. JCV urinary load was determined by real-time quantitative PCR and was independent of gender, age, HIV infection, and CD4+ cell count. Overall, the JCV genotype detected most commonly was 1B, followed by genotypes 2B and 4. The detection and quantitation of JCV-specific antibodies were performed in serum samples by an established enzyme immunoassay (EIA). Antibodies to JCV were observed in 91% of the patients tested, irrespective of HIV infection. A positive correlation between JCV urinary load and antibody titers was demonstrated. The present study provides the first characterization of seroprevalence and urinary excretion of JCV in a Portuguese population and revealed similar results to those observed in other European countries. A comparison between healthy individuals and patients infected with HIV, despite identical values of seroprevalence, showed some differences in the pattern of urinary excretion. J. Med.

Abstract
As new cases arise of progressive multifocal leukoencephalopathy (PML) in patients with multiple sclerosis (MS) treated with the monoclonal antibody natalizumab, a critical discussion about risks and advantages of this specific kind of immunotherapy appears necessary. Practical consequences and treatment options are addressed based on current concepts of PML's pathogenesis in patients treated with natalizumab. Critical patient selection based on risk:benefit considerations, limited therapy regimens, early diagnosis of PML by clinical and paraclinical criteria, and therapeutic perspectives for treating PML are discussed. The risk of PML in patients with MS needs to be continually monitored and should be reduced with all means available to ensure optimal outcome.
