Cytotoxic T Lymphocytes in Treating Patients With Malignancies With BK and/or JC Virus
Acquired Immunodeficiency SyndromeBK Virus Infection6 moreThis phase II trial studies how well donor cytotoxic T lymphocytes work in treating patients with malignancies with BK and/or JC virus. Cytotoxic T lymphocytes are made from donated blood cells that are grown in the laboratory and are designed to kill viruses that can cause infections in transplant patients and may be an effective treatment in patients with malignancies with BK and/or JC virus.

A Trial to Treat Polyomavirus Infections (BKPyV) in Kidney and Simultaneous Kidney Pancreas Transplant...
BK ViremiaKidney Transplant Infection1 moreBEAT-BK will see the effect of immunosuppression reduction/modification with and without IVIG on BKPyV infection, allograft function, allograft loss, acute transplant rejection, immunosuppression load and death in kidney and simultaneous kidney pancreas transplant recipients with polyomavirus infections (BKPyV).

Prevalence of BK Viremia in Simultaneous Liver-Kidney Transplant
Polyomavirus InfectionsBK Viremia2 moreThe human BK polyomavirus is a significant risk factor for renal transplant dysfunction and allograft loss. The prevalence of BK viremia (BKV) following kidney transplantation is estimated to be 10-20%.

Localized Radiation Therapy or Recombinant Interferon Beta and Avelumab With or Without Cellular...
Merkel Cell Polyomavirus InfectionStage IV Merkel Cell Carcinoma AJCC v7This phase I/II trial studies the side effects and how well localized radiation therapy or recombinant interferon beta and avelumab with or without cellular adoptive immunotherapy works in treating patients with Merkel cell carcinoma that has spread to other parts of the body. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Interferon beta is a substance that can improve the body's natural response and may interfere with the growth of tumor cells. Monoclonal antibodies, such as avelumab, may help T lymphocytes kill tumor cells. For cellular adoptive immunotherapy, specific white blood cells are collected from the patient's blood and treated in the laboratory to recognize Merkel cell carcinoma. Infusing these cells back into the patient may help the body build an effective immune response to kill Merkel cell carcinoma. Giving localized radiation therapy or recombinant interferon beta and avelumab with or without cellular adoptive immunotherapy may be a better treatment for Merkel cell carcinoma.

Impact of Immunosuppressive Regimens on Polyomavirus-related Transplant Nephropathy
Polyomavirus InfectionsThe aim of this study is to characterize and evaluate risk factors of polyomavirus nephropathy (PVN) including the impact of three immunosuppressive regimens.
