KI and WU Polyomaviruses and CD4+ Cell Counts in HIV-1–infected Patients, Italy

Emerging Infectious Diseases, 2010
To investigate an association between KI and WU polyomavirus (KIPyV and WUPyV) infections and CD4+ cell counts, we tested HIV-1–positive patients and blood donors.

Human Polyomavirus Infection in Renal Allograft Recipients [PDF]

BMJ, 1973
Cytological and virological studies on 74 patients with functioning renal allografts were undertaken to detect polyomavirus infection of the renal tract. Ten patients (13·5%) were excreting polyomavirus. Virus particles were seen in the electron microscope in urine samples from eight patients. B.K.

Association Between the Time of Day of Post‐Transplant Cyclophosphamide Administration and Haemorrhagic Cystitis After Allogeneic Haematopoietic Stem Cell Transplantation

European Journal of Haematology, EarlyView.
ABSTRACT Objective To evaluate the impact of the time‐of‐day (daytime vs. nighttime) of the infusion of post‐transplantation cyclophosphamide (PTCy) on the occurrence of haemorrhagic cystitis (HC) in adult patients undergoing allogeneic haematopoietic stem cell transplantation (allo‐HSCT).

Structural Basis and Evolution of Glycan Receptor Specificities within the Polyomavirus Family

mBio, 2020
Asymptomatic infections with polyomaviruses in humans are common, but these small viruses can cause severe diseases in immunocompromised hosts. New Jersey polyomavirus (NJPyV) was identified via a muscle biopsy in an organ transplant recipient with ...

Merkel cell carcinoma: an updated guide for pathologists

Histopathology, EarlyView.
Merkel cell carcinoma (MCC) is an aggressive cutaneous neuroendocrine carcinoma for which the differential diagnosis can include other small cell malignancies (especially metastatic small cell carcinoma) or cutaneous carcinoma. Morphologic and immunophenotypic aberrancies in MCC can increase diagnostic challenge.

The lymphocyte function of allogeneic peripheral blood stem cell grafts is associated with relapse and cytomegalovirus reactivation

Transfusion, EarlyView.
Abstract Background Allogeneic hematopoietic stem cell transplantation (HSCT) is a treatment primarily for hematological malignancies. Infections, relapse, and graft versus host disease (GvHD) are some of the most common adverse events following HSCT. We aimed to evaluate whether the lymphocyte function of the stem cell graft was associated with these ...

KI and WU Polyomavirus in Respiratory Samples of SARS-CoV-2 Infected Patients

Microorganisms, 2021
Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) has been declared a global pandemic. Our goal was to determine whether co-infections with respiratory polyomaviruses, such as Karolinska Institutet polyomavirus (KIPyV) and Washington ...

Small‐molecule inhibitors of JC polyomavirus infection [PDF]

Journal of Peptide Science, 2014
The JC polyomavirus (JCPyV) infects approximately 50% of the human population. In healthy individuals, the infection remains dormant and asymptomatic, but in immuno‐suppressed patients, it can cause progressive multifocal leukoencephalopathy (PML), a potentially fatal demyelinating disease.

Merkel Cell Carcinoma With Divergent Differentiation—Or Something Else? A Triphasic Cutaneous Carcinoma With Lineage Plasticity

Journal of Cutaneous Pathology, Volume 53, Issue 11, Page 994-999, November 2026.
ABSTRACT Merkel cell carcinoma (MCC) is a rare, aggressive cutaneous neuroendocrine carcinoma that typically arises in sun‐exposed skin of older or immunosuppressed patients. Combined or collision tumors involving MCC and other cutaneous malignancies are uncommon, and tumors exhibiting more than two distinct malignant phenotypes are exceptionally rare.
