Polyomaviruses and Human Diseases


Book Description

Science never solves apr oblem without creating ten more Geor ge Bernard Shaw How prophetic the above words prove to be when applied to the advances of 20th century medicine. Prior to Banting and Best, chnicians were unaware of the ravages of diabetes, patients simply wasted away and died. Following the purifica tion of insulin, clinicians now had to deal with diabetic retinopathy, diabetic neph ropathy and all the other complications of long-term diabetes. A little over 50 years ago, the first successful human kidney transplant was performed in Boston. The first 30 years of the experience had successes when compared to the alternative but were a constant struggle to get even 50% of the grafts from deceased donors to survive more than a year. However, the science continued to advance knowledge of the immune response. With this came more and increasingly powerful tools for the clinician. Suddenly, success rates of 80-90% at one year were attainable. With this success came new problems, new complications and clinicians now had to worry about the long-term consequences of their therapy as patients were surviving with functional grafts for extended periods. A particular infectious complication evolved with the application of ever more powerful immunosuppressant drugs. Astute clinicians noted that occasionally cellular rejections seemed to get worse with steroids. Despite their best efforts and the use of powerful drugs, patients lost their grafts to overwhelming interstitial infiltrates not seen before.

Human Polyomaviruses


Book Description

Human polyomaviruses are non-enveloped viruses with a circular double-stranded DNA genome of approximately 5,000 base pairs. The members BK virus and JC virus were first isolated in 1971 and are very common in the human population. Simian virus 40 (SV40), although originally isolated from rhesus macaques and accidentally introduced in the human population during massive poliovirus vaccination, may represent a third member of the polyomaviruses that can have man as a natural host. Primary infection with BK or/and JC virus occurs during early childhood. Subsequently, these viruses establish a seemingly life-long harmless latent infection. However, virus reactivation can occur especially in immunocompromised individuals and JC virus has been recognised as the cause of progressive multifocal leukoencephalopathy, while BK virus-associated interstitial nephritis has become an emerging complication in renal transplant patients. The genomes of human polyomaviruses encode two functional classes of proteins: the regulatory proteins large T-antigen, small t-antigen, and agnoprotein, and the structural proteins VP1, VP2 and VP3 that form the capsid. The regulatory proteins can modulate the expression and/or activity of cellular proteins involved in signal transduction, cell cycle regulation, and chromosomal functions. Therefore, they all possess oncogenic potential. Consistent with this, human polyomaviruses are capable of transforming human cells and inducing tumours in rodents, and are implicated in human malignancies. This book focuses on the etiological role of human polyomaviruses in cancer and highlights the mechanisms by which the viral regulatory proteins may contribute to neoplastic transformation of the infected host cells. Possible therapeutic strategies against these viruses will also be discussed.




Immunization Safety Review


Book Description

The Immunization Safety Review Committee was established by the Institute of Medicine (IOM) to evaluate the evidence on possible causal associations between immunizations and certain adverse outcomes, and to then present conclusions and recommendations. The committee's mandate also includes assessing the broader societal significance of these immunization safety issues. While all the committee members share the view that immunization is generally beneficial, none of them has a vested interest in the specific immunization safety issues that come before the group. The committee reviews three immunization safety review topics each year, addressing each one at a time. In this fifth report in a series, the committee examines the hypothesis that exposure to polio vaccine contaminated with simian virus 40 (SV40), a virus that causes inapparent infection in some monkeys, can cause certain types of cancer.

Fenner and White's Medical Virology


Book Description

Fenner and White's Medical Virology, Fifth Edition provides an integrated view of related sciences, from cell biology, to medical epidemiology and human social behavior. The perspective represented by this book, that of medical virology as an infectious disease science, is meant to provide a starting point, an anchor, for those who must relate the subject to clinical practice, public health practice, scholarly research, and other endeavors.

Clinical Virology, Fourth Edition, has been extensively revised and updated to incorporate the latest developments and relevant research. Chapters written by internationally recognized experts cover novel viruses, pathogenesis, epidemiology, diagnosis, treatment, and prevention, organized into two major sections: Section 1 provides information regarding broad topics in virology, including immune responses, vaccinology, laboratory diagnosis, principles of antiviral therapy, and detailed considerations of important organ system manifestations and syndromes caused by viral infections. Section 2 provides overviews of specific etiologic agents and discusses their biology, epidemiology, pathogenesis of disease causation, clinical manifestations, laboratory diagnosis, and management. Clinical Virology provides the critical information scientists and health care professionals require about all aspects of this rapidly evolving field.
