Two weeks later she she presented with fever (T-38.5 C), vomiting, suicidal thought, aggressive behavior, depression and mood changes .CMV –Ag was positive (viral load 470x10^3 copy)-Treated with: GCSF+ Meropenem + Vancomycin + IVIG+ gancyclovir+ valcyte + Floxetine but after two weeks of treatment gancyclovir stopped for bone marrow suppression and severe leucopenia. Afterward she admitted for another five times for abdominal pain, anorexia, mood changes. Medication was Cell cept (750+500)+ sandimun (75+100)+ Prednisolon (7.5)+COTMX. Four months post transplant she admitted again for Cough + rhinorhea , weight loss (3 kg), nausea, vomiting, anorexia, fever (38 C),staring and seizure (3 episodes) . CSF was nl, cultures were negative , brain MRI and brain CT scan – NL, CNS PCR was positive for EBV and CMV and blood CMV PCR load was 1920.
