immunologic reconstitution
The process of restoring normal immune system function following treatment for primary immunodeficiency disorders.
Full Definition
Immunologic reconstitution refers to the gradual restoration of normal immune system components and function following therapeutic interventions such as hematopoietic stem cell transplantation, gene therapy, or enzyme replacement therapy. The process involves the development of functional T-cells, B-cells, and other immune effector cells, along with the establishment of immunological memory. Monitoring reconstitution requires serial laboratory assessments including lymphocyte counts, immunoglobulin levels, vaccine responses, and functional immune assays. Complete reconstitution may take months to years, during which patients remain at increased risk for infections.
