Abstract
Background: HIV-associated CD8 encephalitis (CDE) is a severe inflammatory disorder characterized by infiltration of the brain by CD8+ T-lymphocytes in HIV positive patients, often when the virus is well-controlled by anti-retroviral therapy (ART). Hallmark clinical features include headache, confusion and progressive cognitive decline. Most patients who receive prompt corticosteroid therapy evolve favorably, though if left untreated, CDE can lead to coma and even death. The therapeutic impact of altering the ART regimen while giving corticosteroids remains unclear. Methods: Patient chart, functional measures, and laboratory findings were reviewed for the length of the patient’s two hospitalisations for CDE in 2019 and 2021. Results: Here we present a case of an HIV positive 43-year-old male who presented with headache, confusion and memory issues both in 2019 and 2021. Imaging and lumbar puncture guided the diagnosis of CDE in 2019, while careful patient history on the patient’s second hospitalisation confirmed the diagnosis of HIV encephalitis due to medication non-compliance in 2021. Conclusions: This case adds to the current state of knowledge regarding the clinical presentation of CD8 encephalitis, while highlighting both similarities and differences with other CNS pathology seen in the context of HIV.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
