We performed a single-center retrospective cohort study of patients with MASLD evaluated for LT from 2014 to 2021. The utility of the previously defined total SIPAT cutoff (<21 [excellent/good candidates] vs. ≥21 [minimally acceptable/high-risk candidates]) was studied. Multivariable logistic regression analyses examined associations between continuous SIPAT scores and LT waitlisting outcomes. The Youden J statistic was used to identify the optimal SIPAT cutoff for patients with MASLD. A total of 480 patients evaluated for transplant with MASLD were included. Only 9.4% of patients had a SIPAT score ≥21. Patients with SIPAT score ≥21 had higher hemoglobin A1c compared to patients with lower psychosocial risk (median [IQR]: 7.8 [6.0-9.7] vs. 6.6 [5.8-7.9]; p = 0.04). There were no other differences in metabolic comorbidities between SIPAT groups. Increasing SIPAT score was associated with decreased odds of listing (OR: 0.82 per 5-point increase; p = 0.003) in multivariable models. A SIPAT of ≥12 was identified as the optimal cutoff in this population, resulting in an adjusted OR for a listing of 0.53 versus SIPAT <12 ( p = 0.001). In this large cohort of patients with MASLD evaluated for LT, few patients met the previously defined high SIPAT cutoff for transplant suitability.

Here, we collected serial peripheral blood mononuclear cell samples spanning from pre-LTx to 1 year after LTx and available biopsies during the TCMR episodes from 26 rejecting patients, and serial peripheral blood mononuclear cell samples were collected from 96 nonrejectors. Immunophenotypic and repertoire analyses were integrated on T cells from rejectors, and they were longitudinally compared to nonrejected patients. Donor-reactive T-cell clone was identified and tracked by cross-matching with the mappable donor-reactive T-cell receptor repertoire of each donor-recipient pair in 9 rejectors and 5 nonrejectors. Before transplantation, the naive T-cell percentage and T-cell receptor repertoire diversity of rejectors was comparable to that of healthy control, but it was reduced in nonrejectors. After transplantation, the naïve T-cell percentages decreased, and T-cell receptor repertoires were skewed in rejectors; the phenomenon was not observed in nonrejectors. Alloreactive clones increased in proportion in the peripheral blood of rejectors before TCMR for weeks. The increase was accompanied by the naïve T-cell decline and memory T-cell increase and acquired an activated phenotype. Intragraft alloreactive clone tracking in pre-LTx and post-LTx peripheral blood mononuclear cell samples revealed that the pretransplant naïve T cells were significant contributors to the donor-reactive clones, and they temporarily increased in proportion and subsequently reduced in blood at the beginning of TCMR.

Evidence has emerged supporting the transplantation of carefully selected patients with primarily neuropsychiatric symptoms and compensated cirrhosis. The rationale behind this approach is the potential for surgery to improve copper homeostasis and consequently ameliorate neuropsychiatric symptoms. However, several questions remain unanswered, such as how to establish thresholds for assessing pretransplant neuropsychiatric impairment, how to standardize preoperative neurological assessments, and how to define postoperative outcomes for patients meeting these specific criteria.
