Serum Levels of Candida albicans 65-kDa Mannoprotein (CaMp65p) Correlate with Liver Disease in Patients with Alcohol Use Disorder
Bibliographic record
Abstract
Alcohol-associated liver disease is a global health burden with high morbidity and mortality, and the fungal microbiome is important for its progression. In particular, Candida albicans and C. albicans-reactive T helper 17 (Th17) cells contribute to alcohol-associated liver disease. Specific C. albicans antigens that activate Th17 cells during this disease are unknown. The C. albicans 65 kDa mannoprotein (CaMp65p) is one of the most abundant and immunodominant proteins of C. albicans, and is capable of eliciting robust T cell and interleukin (IL)-17A responses. The aim of this study was to measure levels of CaMp65p in serum of patients with alcohol use disorder and liver disease. Serum CaMp65p levels were measured in the serum of 60 patients with alcohol use disorder using an indirect competitive Enzyme-Linked Immunoabsorbent Assay (ELISA). Serum CaMp65p levels were correlated with liver disease severity. Serum CaMp65p levels positively correlated with several clinical and biochemical markers of liver injury and disease within the patient group with alcohol use disorder, including serum aspartate aminotransferase (AST; R = 0.33, p = 0.0092), alanine aminotransferase (ALT; R = 0.27, p = 0.037), gamma-glutamyl transferase (GGT; R = 0.35, p = 0.0055) and alkaline phosphatase (R = 0.36, p = 0.0052), and with the circulating M65 fragment of cytokeratin 18 (CK18-M65; R = 0.51, p = 0.0012), a marker of hepatocyte death. In addition, patients with alcohol use disorder in the upper quartile had significantly higher liver stiffness (p = 0.0022). Serum CaMp65p was significantly higher in patients with fibrosis stage F2–F4 as compared with patients with no or minimal fibrosis F0–F1 (p = 0.0082). The area under the curve (AUC) for detecting F2–F4 fibrosis was 0.70. Elevated serum CaMp65p levels are associated not only with more severe hepatic injury, but also with liver fibrosis in patients with alcohol use disorder. Therefore, CaMp65p may serve as a non-invasive biomarker for fibrosis assessment in patients with alcohol use disorder.

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.
