Plasma Protein Binding of Drug - theteche.com High total protein levels associated with increased globulin may be seen in dehydration, in response to acute infections such as pneumonia and hepatitis, and in chronic inflammatory conditions such as rheumatoid arthritis and systemic lupus erythematosus (SLE). investigating a specific symptom, such as peripheral oedema, diagnosing an inflammatory process or autoimmune disorder (for example, antinuclear antibody testing in the assessment of systemic lupus erythematosus [SLE]), diagnosing bone marrow disorders, including multiple myeloma, testing for immunodeficiency in patients with recurrent infections, assessing immunity to infections, such as hepatitis B or rubella, through specific antibody assays. Abnormalities in plasma proteins may be primary (the cause of specific pathologies) or secondary (the result ofa wide range of disease processes). (PDF) Impact of hypoalbuminemia on plasma protein binding Supported by NIAID/NIH grant UM1AI104681. The results for the entire set of compounds indicate a lower protein binding for compounds in human plasma than for the same compounds in rat plasma.
