Abstract
Severe abdominal pain followed by inappropriate antidiuretic hormone secretion (SIADH) preceding by several days the skin manifestation of varicella-zoster virus (VZV) infection in an immunocompromised patient is described. This is a rare presentation of a severe infection described previously only once in a chronic myeloid leukemia (CML) patient 5 months post allo-BMT during immunosuppressive treatment with cyclosporin A. This is the first case described in the setting of non-myeloablative preparation with fludarabine and melphalan and followed by donor leukocyte infusion (DLI) 2 and 4 months post allo-BMT. The influence of these factors on development of VZV virus infection is discussed. We also highlight the high incidence and high mortality in VZV infection in immunocompromised patients as well as the frequent atypical presentation. Bone Marrow Transplantation (2000) 26, 231–233.
