Filter by:The major goal of Part A of this study is to establish a National PAP Registry to help make reliable new research tests available to doctors to improve the diagnosis of PAP, increase awareness and knowledge of PAP, and give patients a 'seat at the table' in planning and conducting PAP research including the clinical testing of several new potential therapies. The major goal of Part B of this study is to define the natural history of autoimmune PAP (aPAP), develop a disease severity score that reflects how aPAP patients feel and function, and to develop and test novel tools to measure the severity of aPAP lung disease.

The purpose of the study is to evaluate if inhaled granulocyte-macrophage colony stimulating factor delay the increase in alveolar-arterial oxygen difference, compared to no treatment, for adult patients with mild-to-moderate autoimmune pulmonary alveolar proteinosis in China over a two-year period.
The purpose of this study is twofold: to assess routine cat scan (CT) imaging as a biomarker for removal of lipoprotein surfactant via lung lavage (where CT is the gold-standard imaging technique for density quantification), and to utilize a novel UTE MRI protocol to similarly quantify surfactant removal. This study will also serve to generate baseline scanning that may aid in developing analytical tools to evaluate and treat specific lung regions of patients with PAP.
The purpose of this study is to establish an efficient and economic treatment scheme by evaluation of the safety and efficacy of subcutaneous injection of low-dose rhGM-CSF, or of similar injection after whole lung lavage , in patients with PAP.
Background: - Healthy people have white blood cells that protect them against bacteria, viruses, and fungi. However, some people have diseases which cause the body to make white blood cells that do not work properly. These white blood cells can attack the body s own proteins. These types of diseases are called anti-cytokine autoantibody-associated diseases. They can cause severe illnesses and even death. They are also difficult to treat with standard drugs. - Rituximab is a drug used to treat rheumatoid arthritis. It attacks white blood cells that do not work properly. Currently, it is not approved for treating anti-cytokine autoantibody-associated diseases. However, researchers think that it may be able to help treat people with these immune diseases. Objectives: - To see if rituximab is a safe and effective treatment for anti-cytokine autoantibody-associated diseases. Eligibility: - Individuals at least 18 years of age who have anti-cytokine autoantibody-associated diseases. - Participants must also be enrolled in a related immune disorder study at the National Institutes of Health. Design: - The study will last 24 months. Participants will take rituximab for 6 months and have follow-up visits for the remaining 18 months. - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Other samples will be collected as needed if participants currently have an infection. - Participants will enter the hospital for 1 week at the start of treatment. They will have four doses of rituximab given 2 days apart. This first treatment will be monitored with frequent blood tests. - Over the next 6 months, participants will have four more doses of rituximab given about 1 month apart. Treatment will be monitored with frequent blood tests and sample collections as needed. - There will be four follow-up study visits at 3, 6, 12, and 18 months after the last dose of rituximab.
The purpose of this study is to evaluate the therapeutic efficacy of inhaled recombinant human GM-CSF in individuals with hereditary Pulmonary Alveolar Proteinosis (PAP) due to partial dysfunction of the GM-CSF receptor.
This is a prospective, randomized, open-label, long-term, phase 2 study of inhaled granulocyte/macrophage-colony stimulating factor following whole lung lavage therapy in patients with autoimmune pulmonary alveolar proteinosis.
The purpose of this study is to determine whether the use of rituximab is effective in treating pulmonary alveolar proteinosis by leading to an improvement in lung function and disease status.
This is a study to determine the efficacy and safety of granulocyte-macrophage colony-stimulating factor (GM-CSF, sargramostim) administered subcutaneously to patients with pulmonary alveolar proteinosis (PAP).
