Relative Contribution of Pharmacokinetics and Immune Signatures to Clinical Outcomes in Patients With HIV-associated Cryptococcal Meningitis.
Article in Open forum infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Host immune responses to HIV-associated cryptococcal meningitis are critical in disease outcome. Their interaction with antifungal drug exposure is poorly understood. This study explored associations between immune biomarkers, antifungal drug exposure, and clinical outcomes in HIV-associated cryptococcal meningitis. Methods: We analyzed serial plasma and cerebrospinal fluid immune biomarkers from 64 participants recruited from the AMBITION-cm trial. We estimated individual-level exposure to amphotericin B, flucytosine, and fluconazole. Associations between immune biomarkers, pharmacokinetic parameters, and clinical outcomes were evaluated. Results: An inflammatory cerebrospinal fluid response, characterized by coordination between tumor necrosis factor-α, granulocyte colony-stimulating factor, and interleukin-7 signaling, was linked to low fungal burden, low intracranial pressure, and survival. However, the value of specific immune biomarkers did not predict EFA or mortality. Exposure to amphotericin B was significantly associated with EFA. Conclusions: Favorable clinical outcomes from HIV-associated cryptococcal meningitis are associated with coordinated inflammatory and cytotoxic responses in the central nervous system. Antifungal drug exposure was the dominant predictor of EFA.
