Successful immune reconstitution in severe combined immunodeficiency despite Epstein-Barr virus and cytomegalovirus infections.

Journal Article

Cytomegalovirus (CMV) and Epstein-Barr virus (EBV), frequently found in the acquired immune deficiency syndrome (AIDS), have been suspected of contributing to the latter immunodeficiency. The ability of normal HLA-identical sibling bone marrow to reconstitute an 8-month-old infant with severe combined immunodeficiency infected with these two viral agents is of interest. After presentation with severe mucocutaneous candidiasis, cavitary pulmonary disease, nodular cutaneous lesions, and hepatic abscesses containing acid-fast organisms, immunologic studies revealed lymphopenia, 1-3% T cells, and no lymphocyte responses to mitogens. Prior to transplantation, the infant's blood B lymphocytes grew spontaneously in culture, suggesting they were infected with EBV. Indeed, an appropriate antibody response to EBV was detected at 2 months post-transplantation. At 3 weeks postgrafting, neutropenia and cholestatic jaundice developed without other signs of graft versus host disease. Liver biopsy demonstrated CMV but no EBV by DNA hybridization. There was evidence of T- and B-cell function by 2 weeks postgrafting, including vigorous in vivo and in vitro responses to candida. Although the blood lymphocyte T4:T8 ratio was inverted at 2 weeks, it reverted to normal by 6 weeks post-transplantation. All clinical disease resolved by 8 months and karotyping revealed all T and B lymphocytes to be XX. Thus, despite infections with both CMV and EBV, complete immunologic reconstitution was achieved in this, the most severe of all genetically determined immunodeficiency conditions, arguing against these viruses having a major role in the failure of bone marrow transplantation in AIDS.
