Background: Ganciclovir-resistant (ganR) cytomegalovirus (CMV) is an emerging and important problem in solid organ transplant (SOT) recipients. Only through direct comparison of ganR- and ganciclovir-sensitive (ganS) CMV infection can risk factors and outcomes attributable specifically to ganciclovir resistance appropriately be determined. Methods: We performed a retrospective, case-control (1:3) study of SOT recipients with genotypically confirmed ganR-CMV (n = 37) and ganS-CMV infection (n = 109), matched by donor/recipient CMV serostatus, year and organ transplanted, and clinical manifestation...

Cytomegalovirus (CMV) is a frequent complication of hematopoietic stem cell transplant in pediatric patients, with significant morbidity and mortality. Antiviral drugs are used as prophylactic, preemptive or therapeutic medicines; however, no uniform guidelines exist for the best strategy to prevent CMV disease. Resistance to standard antiviral therapies can lead to further difficulty in managing CMV disease. Studies for investigational therapies are underway and could provide options for treatment of resistant CMV, while limiting toxicities associated with currently used antiviral therapies...

Cytomegalovirus (CMV) infects approximately 40-90% of the world population. The infection is usually asymptomatic in immunocompetent persons. However, it may have negative impact on physiological status or accompanying diseases especially in the elderly. In particular, increasing number of data suggests that persistent infection with CMV is associated with accelerated aging of the immune system accompanying by the decrease in the number of naïve T cells, the increase in in the number of late-differentiated T cells, and reduced TCD4/ TCD8 ratio...

Cytomegalovirus (CMV) infection remains a major complication of solid organ transplantation. Because of management of CMV is variable among transplant centers, in 2011 the Spanish Transplantation Infection Study Group (GESITRA) of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) developed consensus guidelines for the prevention and treatment of CMV infection in solid organ transplant recipients. Since then, new publications have clarified or questioned the aspects covered in the previous document...

BACKGROUND: Requirements on tissue fixatives are getting more demanding as molecular analysis becomes increasingly relevant for routine diagnostics. Buffered formaldehyde in pathology laboratories for tissue fixation is known to cause chemical modifications of biomolecules which affect molecular testing. A novel non-crosslinking tissue preservation technology, PAXgene Tissue (PAXgene), was developed to preserve the integrity of nucleic acids in a comparable way to cryopreservation and also to preserve morphological features comparable to those of formalin fixed samples...

The VICTOR study showed comparable efficacy of treatment with intravenous ganciclovir and oral valganciclovir for cytomegalovirus (CMV) disease in solid organ transplant recipients. Oral therapy is now recommended treatment in clinical practice and guidelines. The VICTOR biobank was used in a series of post hoc analyses that yielded unique and clinically valuable insights into CMV treatment and pathogenesis. For example, the importance of tailoring therapy to initial viral load, the effect of immunosuppression on outcomes, and the need to continue therapy until undetectable viral load to prevent recurrence and emergence of resistant strains...

Immune thrombocytopenic purpura (ITP) is characterized by a decreased platelet count caused by excess destruction of platelets and inadequate platelet production. In many cases, the etiology is not known, but the viral illness is thought to play a role in the development of some cases of ITP. The current (2011) American Society of Hematology ITP guidelines recommend initial diagnostic studies to include testing for HIV and Hepatitis C. The guidelines suggest that initial treatment consist of observation, therapy with corticosteroids, IVIG or anti D...

Cytomegalovirus infection in kidney transplantation is associated with increased morbidity and mortality through direct and indirect effects. International guidelines had been recently updated, focusing on diagnostic, prevention strategies and curative treatment. Cytomegalovirus-specific immune response plays also an important function in controlling the virus. Here, we propose to present the different components of this specific immune response and the advantages of immune monitoring for patient's management: identification of patients who require a treatment, adaptation of curative treatment length, guidance for resistance genotypic testing...
