Abstract
In a randomized double‐blind longitudinal study with 30 HIV‐1‐positive patients with AIDS‐related complex or stage Walter‐Reed 5 disease, the effectiveness of intravenous immunoglobulin (IVIG) was tested for correcting eventual immune dysregulation. Although the IVIG‐treated patients showed an improvement of their clinical score, no significant changes were observed in lymphocyte phenotypes, activation markers, immunoglobulins and subclasses, lymphocyte turnover or in indicators of acute inflammation. Since severe bacterial infections or autoimmune processes usually leading to IVIG therapy were not prevalent in the patients of the study, such therapy should probably be reserved for later stages of the disease. HIV‐1 antigen expression in blood lymphocytes remained uninfluenced by IVIG treatment.
