Abstract :
Symptomatic cytomegalovirus (CMV) infections are rare in patients with no previous history of immunosuppressive therapy or condition. A 33-year-old woman with type-2 diabetes, endstage renal disease (ESRD) and unexplained lower extremity weakness was admitted with failure to thrive, ongoing hemolysis, low haptoglobin and C3 levels and suppressed IgM and IgG globulin fractions. Multiple cultures and serologic workup for autoimmune disorders remained negative. CMV viral titer by serum polymerase chain reaction (PCR) revealed massive elevation at 9.2 million copies/mL. Initial CMV IgG titer was positive, IgM titer remained consistently negative and CMV was recovered from cerebrospinal fluid, as well.
She received treatment with I.V. ganciclovir, CMV immune globulin (CytoGam) and three sessions of plasmapheresis (PLEX). The extreme viremia without neutropenia, lack of IgM antibody reconversion and CMV-mediated hemolysis with a low complement level were all very unusual features. Timely initiation of PLEX may have contributed to recovery.
