Background: Kaposi sarcoma herpesvirus (KSHV)-associated inflammatory cytokine syndrome (KICS) and KSHV-multicentric Castleman disease (MCD) occur in people living with HIV. These diseases cause severe inflammation that can be fatal if not treated. Objective: To test a drug (pacritinib) in people with KSHV-associated KICS or MCD. Eligibility: People aged 18 years and older with KSHV-associated KICS or MCD. They must have at least one symptom. Design: Participants will be screened. They will have a physical exam with blood tests and tests of their heart function. They will have imaging scans. Their ability to perform everyday tasks will be reviewed. In some participants who have Kaposi sarcoma (KS) with KICS or MCD, these individuals may need a bronchoscopy and/or endoscopy of the upper or lower intestine: A flexible tube with a camera and a light source will be inserted through the mouth or anus to see these structures and assess any KS. Pacritinib is a capsule taken by mouth. Participants will take the drug twice a day, every day, for up to 24 weeks. They will write down each dose in a diary. Participants will visit the clinic 3 times in the first 4 weeks. Their visits will taper to once every 4 weeks. Imaging scans, blood tests, and other tests will be repeated during these visits. Participants will give samples of saliva. They may opt to allow tissues samples to be taken from their skin and lymph nodes. Participants will have follow-up visits 7 days and 30 days after their last dose of pacritinib. After that, they will visit the clinic every 3 months for up to 1 year. The physical exam and blood, heart, and imaging tests will be repeated at these visits.
Background: Primary effusion lymphoma (PEL), plasmablastic lymphoma (PBL), and Multicentric Castleman Disease (MCD) are aggressive forms of cancer that affects cells in the immune system and lymph nodes. How they develop is not well understood, and these diseases do not respond well to standard treatments for other types of lymphomas. Objective: To test a drug treatment (daratumumab SC) in people with PEL, PBL, or MCD. Eligibility: People aged 18 and older with PEL, PBL, or MCD who must have failed to respond to therapy or they must be unable to receive standard treatment for the disease. Design: Participants will be screened. They will have a physical exam with blood tests. They will have imaging scans and tests of their heart and lung function. They may need to have a biopsy: tissue or fluid will be collected. They will have an eye exam. Daratumumab SC is given as an injection into the fat under the skin in the abdomen. This takes 3 to 5 minutes. Participants will receive the treatment once a week for 8 weeks; then every 2 weeks for 16 weeks; then every 4 weeks for up to 24 months. Participants will have other tests during the study period. These may include lumbar punctures: A needle will be inserted between the bones of the spine to draw some fluid from the area around the spinal cord. Participants may also have a thoracentesis: A needle or plastic tube will be inserted into the space around the lungs to withdraw fluid. Participants will have more imaging scans and blood tests. Follow-up visits will continue after treatment ends. Participants will be in the study for up to 5 years.
This study collects blood and tissue samples for research of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS)-related cancers. Collecting blood and tissue samples and studying biomarkers in the laboratory may help doctors to learn how are biologic or genetic factors related to HIV and cancers that occur commonly in people living with HIV.
BACKGROUND: * A number of important scientific advances can be made through the study of blood, bone marrow, tumor, or other tissue samples from patients with HIV infection, infection with Kaposi s sarcoma associated herpesvirus (KSHV), infection with other oncogenic viruses, or cancer. * This protocol provides a mechanism to affect a variety of such studies. OBJECTIVES: -Acquisition of serum, circulating cells, bone marrow, and tumor or normal tissue samples from participants with HIV infection, KSHV infection, or with cancer. ELIGIBILITY: -Eligibility criteria include age 18 years or older and at least one of the following: Exposure risk to HIV, KSHV, or HPV; HIV seropositive; KSHV seropositive; EBV seropositive; HTLV-1 seropositive; malignancy, Castleman s disease, or skin lesions with appearance of Kaposi s sarcoma; or cervical or anal intraepithelial lesion. DESIGN: * Up to 999 subjects will be enrolled in this study. * Blood samples may be collected at the initial visit, and at follow-up visits. * Other fluids/excretions may be collected (such as urine, saliva, semen, and stool). * Tumor samples may be obtained by fine needle aspirate, by removal of pleural or peritoneal fluid, by skin punch biopsy, or by excisional biopsy, providing the tumor is accessible with minimal risk to the participants. * Specific risks will be described in a separate consent to be obtained at the time of the biopsy. * Samples will be studied in the HIV and AIDS Malignancy Branch, CCR, NCI; laboratories in NCI-Frederick; or those of collaborating investigators.
The purpose of this study is to collect clinical, laboratory, and patient survey data from patients with Castleman disease to improve understanding, diagnosis, and treatment of the disease.
