Impaired Hepatitis C Virus (HCV)–Specific Interferon-γ Responses in Individuals With HIV Who Acquire HCV Infection: Correlation With CD4+ T-Cell Counts
Bibliographic record
Abstract
Studies examining the effect of coinfection with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) on the HCV-specific immune response in acute HCV infection are limited. This study directly compared acute HCV-specific T-cell responses and cytokine profiles between 20 HIV/HCV-coinfected and 20 HCV-monoinfected subjects, enrolled in the Australian Trial in Acute Hepatitis C (ATAHC), using HCV peptide enzyme-linked immunospot (ELISPOT) and multiplex in vitro cytokine production assays. HIV/HCV coinfection had a detrimental effect on the HCV-specific cytokine production in acute HCV infection, particularly on HCV-specific interferon γ (IFN-γ) production (magnitude P = .004; breadth P = .046), which correlated with peripheral CD4(+) T-cell counts (ρ = 0.605; P = .005) but not with detectable HIV viremia (ρ = 0.152; P = .534).

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.
