T Cell Exhaustion and Function State Correlated With Outcomes in Patients With Intra-Abdominal Candidiasis.
Article in Mycoses, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionIntra-abdominal candidiasis (IAC) still has a high mortality rate despite prompt antifungal therapy due to immunosuppression. T cell exhaustion is an important manifestation of immunosuppression. This study aimed to explore the expression pattern of exhaustion-related molecules in patients with IAC and determine the possible association between dynamic trends and prognosis.
methodsPatients with IAC were enrolled, and non-IAC critically ill patients were included as controls. Peripheral blood mononuclear cells (PBMCs) were analysed by flow cytometry to determine the expression levels of T cell exhaustion-related markers. T cells isolated from PBMCs were stimulated by IL-2 in α-CD3/α-CD28 medium to compare intracellular cytokine production and proliferative capacity.
resultsA total of 34 patients with IAC and 35 controls were enrolled in this study. Patients with IAC had a significant decrease in lymphocytes. CD4+ and CD8+ T cells from patients with IAC had a significantly higher level of immune checkpoint molecules, such as programmed cell death protein 1 (PD-1), cytotoxic T-lymphocyte antigen 4 (CTLA4), and B and T lymphocyte attenuator (BTLA), and exhibited a consistently impaired cytokine-secreting function. Increased exhaustion-associated molecules and deteriorating dysfunction were detected in non-survivors, while survivors demonstrated the opposite tendency. Patients with impaired granzyme B (GZMB) production function who died from IAC over the course of the disease had higher levels of PD-1 expression in CD8+ T cells.
conclusionsT cells from patients with IAC displayed an immunosuppressive phenotype of T cell exhaustion. Sustaining exhaustion status and deteriorated dysfunction were associated with poor prognosis. Persistently increased PD-1 expression and impaired GZMB secretion in CD8+ T cells were linked to worse outcomes. Immunoadjuvants reversing T cell exhaustion have promising prospects in treating IAC and improving prognosis.
