1. Combined Heart and Kidney Transplantation: Initial Clinical Experience
ABSTRACT Introduction: Combined solid organ transplantation is infrequently performed in Brazil. The objective of this article is to present our initial experience with combined heart and kidney transplantation. Methods: From January 2007 to December 2019, four patients were submitted to combined heart and kidney transplantation. Their mean age was 55.7±4

2. Molecular detection of Merkel cell polyomavirus in basal cell carcinoma and perilesional tissue: a cross-sectional study,
Resumo Embora se acredite amplamente que a atenção francesa a Nietzsche nos anos 1960 era uma resposta à publicação das lições de Heidegger sobre Nietzsche em 1961, defendo que o aparecimento de Nietzsche na lista de leitura do exame de agrégation de philosophie fornece a melhor explicação para a emergência do chamado “New Nietzsche” em sua as

3. Renal transplant patients with preformed anti-HLA antibodies: early biopsy findings and clinical outcomes
Resumo Introdução: A fibrose renal é o desfecho de um processo iniciado no transplante, com reperfusão, isquemia e inflamação precoce, que progride ao longo do tempo com fenômenos imunológicos e não imunológicos. A identificação de marcadores morfológicos e a intervenção precoce poderiam melhorar a função e a sobrevida do enxerto. Objetivo

4. Polyomaviruses BK and JC DNA infection in peripheral blood cells from blood donors
ABSTRACT Objectives: To investigate the prevalence of human polyomavirus (BK and JC viruses) infection in peripheral blood mononuclear cells of healthy blood donors. Methods: The study included 250 healthy blood donors. Five-milliliter blood was drawn into sterile EDTA tubes and PBMCs were isolated from whole blood. The isolated PBMCs were counted and stor

5. BK virus salivary shedding and viremia in renal transplant recipients
Abstract Objectives: This study aimed to verify the presence of polyomavirus BK (BKPyV) in the saliva of kidney transplant recipients and to correlate it with blood viremia. Material and Methods: We have conducted a cross-sectional study with a sample involving 126 renal transplant recipients. 126 samples of saliva and 52 samples of blood were collected fr

6. Human polyomaviruses and cancer: an overview
The name of the family Polyomaviridae, derives from the early observation that cells infected with murine polyomavirus induced multiple (poly) tumors (omas) in immunocompromised mice. Subsequent studies showed that many members of this family exhibit the capacity of mediating cell transformation and tumorigenesis in different experimental models. The transfo

7. Merkel cell carcinoma in an immunosuppressed patient
Abstract Merkel cell carcinoma is an uncommon neuroendocrine carcinoma with a rising incidence and an aggressive behavior. It predominantly occurs in older patients, with onset occurring at a mean age of 75-80 years. Recognized risk factors are ultraviolet sunlight exposure, immunosuppression, and, more recently, Merkel cell polyomavirus. We report a case of

8. Desempenho de métodos diagnósticos no rastreio de nefropatia pelo vírus BK em pacientes transplantados renais
Resumo A citologia urinária e a reação da cadeia da polimerase em tempo real (qPCR) em amostras de sangue e/ou urina são comumente utilizados para rastrear nefropatia associada ao polyomavirus (PVAN), em pacientes transplantados renais. Entretanto, poucos estudos comparam diretamente esses testes diagnósticos quanto ao desempenho para predizer esta comp

9. JC virus/human immunodeficiency virus 1 co-infection in the Brazilian Amazonian region
Abstract JC virus (JCV) is a member of the Polyomaviridae family and is associated to a severe disease known as progressive multifocal leukoencephalopathy, PML, which is gradually increasing in incidence as an opportunistic infection among AIDS patients. The present study aimed to investigate the occurrence of JCV among HIV-1 carriers including their types a

11. JC polyomavirus infection in candidates for kidney transplantation living in the Brazilian Amazon Region
This study evaluated the relative occurrences of BK virus (BKV) and JC virus (JCV) infections in patients with chronic kidney disease (CKD). Urine samples were analysed from CKD patients and from 99 patients without CKD as a control. A total of 100 urine samples were analysed from the experimental (CKD patients) group and 99 from the control group. Following

12. Progressive multifocal leukoencephalopathy restricted to the posterior fossa in a patient with systemic lupus erythematosus
Progressive multifocal leukoencephalopathy is a neurological infectious disease caused by the John Cunningham polyomavirus (JCV), an opportunistic agent with worldwide distribution. This disease is frequently seen in immunosuppresed patients and rarely associated with systemic lupus erythematosus. In the central nervous system PML demyelinating lesions occur
