2 Clinical Trials for Various Conditions
Background: - KSHV inflammatory cytokine syndrome (KICS) is a newly recognized disease caused by Kaposi sarcoma-associated herpesvirus (KSHV). This virus can cause cancer. People with KICS can have severe symptoms. They include fever, weight loss, and fluid in the legs or abdomen. People with KICS may also be at risk of getting other cancers associated with KSHV. These cancers include Kaposi sarcoma and lymphoma. Because KICS is a newly identified disease, more information is needed on how the disease works and what can be done to treat it. Objectives: - To collect genetic and medical information from people with KSHV inflammatory cytokine syndrome. Eligibility: - Individuals at least 18 years of age who have Kaposi sarcoma herpes virus and symptoms that resemble those caused by KICS. Design: * Participants will have regular study visits. The schedule will be determined by the study researchers. * Participants will provide a complete medical history and have a full physical exam. Blood and urine samples will be collected as well. * People with KICS that requires treatment may get new experimental treatments. These treatments may include antiviral drugs and chemotherapy drugs, depending on the nature of the disease. * Participants will have imaging studies, such as chest x-rays and computed tomography scans, to study the tumors. * Bone marrow and lymph node biopsies may be done to collect tissue samples for study. * Participants who have Kaposi sarcoma will have photographs taken of their lesions.
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.
