Severe amnesia associated with human herpesvirus 6 encephalitis after bone marrow transplantation
Bibliographic record
Abstract
BACKGROUND: Human herpesvirus 6 (HHV-6) appears to have a predilection for immunocompromised patients and has been implicated as a cause of posttransplant encephalitis. However, the pathogenesis, as well as the appropriate means of diagnosis and treatment of HHV-6 encephalitis is unclear. METHOD: We describe a case of a 20-year-old male university student with anemia who presented with an acute, severe amnesia 1 month after bone marrow transplantation. His illness was subsequently attributed to HHV-6 encephalitis. RESULTS: Cerebrospinal fluid analysis was consistent with encephalitis and polymerase chain reaction confirmed the presence of HHV-6 DNA in both cerebrospinal fluid and serum. No other herpes virus particles were detected. MRI showed bilateral hippocampal involvement. Treatment with acyclovir resulted in a decrease in serum HHV-6 DNA to undetectable levels, coincident with improvement of both memory and lesions on MRI. CONCLUSIONS: This case provides strong clinical and radiological evidence of the reversibility of this disease process and supports the recommendations for empiric treatment of post transplant patients with laboratory evidence of HHV-6 infection, culture or polymerase chain reaction, plus clinical symptoms compatible with HHV-6 infection.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
