RESUMO

BACKGROUND: Nonalcoholic steatohepatitis (NASH) is the fastest-growing indication for liver transplantation (LT). Sex disparities among patients with cirrhosis on the LT waitlist are well known. We wanted to understand these disparities further in women with end-stage liver disease patients listed for NASH cirrhosis in a contemporary cohort. METHODS: We used data from the Scientific Registry of Transplant Recipients to assess sex racial, and ethnic differences in NASH patients listed for LT. Adults transplanted from August 1997 to June 2021 were included. Inferential statistics were used to evaluate differences with univariate and multivariate comparisons, including competitive risk analysis. RESULTS: During the study time period, we evaluated 12 844 LT for NASH cirrhosis. Women were transplanted at a lower rate (46.5% versus 53.5%; P  < 0.001) and higher model for end-stage liver disease (MELD) (23.8 versus 22.6; P < 0.001) than men. Non-White women were transplanted at a higher MELD (26.1 versus 23.1; P  < 0.001) than White women and non-White male patients (26.1 versus 24.8; P  < 0.001). Graft and patient survivals were significantly different ( P  < 0.001) between non-White women and White women and men (White and non-White). CONCLUSIONS: Evaluation of LT candidates in the United States demonstrates women with NASH cirrhosis have a higher MELD than men at LT. Additional disparities exist among non-White women with NASH as they have higher MELD and creatinine at LT compared with White women. After LT, non-White women have worse graft and patient survival compared with men or White women. These data indicate that non-White women with NASH are the most vulnerable on the LT waitlist.

RESUMO

BACKGROUND: There is a paucity of evidence on the risk of donor-recipient transmission of the SARS-CoV-2 in solid organ transplant recipients. Initial impressions suggest non-lung solid organs may be safely transplanted from SARS-CoV-2-positive donors without risk of viral transmission. METHODS: We reviewed clinical results of transplants in which SARS-CoV-2-negative recipients received non-lung solid organs from SARS-CoV-2-positive donors at a single transplant center. No prisoners were used in this study, and participants were neither coerced nor paid. The manuscript was created in compliance with the Helsinki Congress and the Declaration of Istanbul. RESULTS: Between June 2021 and January 2023, we transplanted 26 solid organs, including 13 kidneys, 8 livers, 3 hearts, and 1 simultaneous heart and kidney, from 23 SARS-CoV-2-positive donors into 25 SARS-CoV-2 negative recipients. Two of the recipients had a positive SARS-CoV-2 real-time polymerase chain reaction after transplantation, but otherwise, patients had no SARS-CoV-2-related complications, and all patients to date are alive with excellent allograft function. CONCLUSION: Transplantation of non-lung solid organs from SARS-CoV-2-positive donors into uninfected recipients can be safely performed without adverse effects from SARS-CoV-2.

RESUMO

INTRODUCTION: Complete conversion of calcineurin inhibitor (CNI) immunosuppressant therapy to non-nephrotoxic agents such as mycophenolate mofetil (MMF) is controversial, but may be safe in selected patients, although appropriate protocols and long-term benefits of conversion are not well reported. METHODS: We analyzed all liver transplant (LT) recipients at our institution who were converted from CNI-based therapy to MMF monotherapy because of renal dysfunction (n = 23) and compared them with patients remaining on CNI-based therapy (n = 23). Renal function, rejection episodes, and markers of CNI-related comorbidities (lipid profile, blood pressure, and glycosylated hemoglobin) were noted. RESULTS: Overall, serum creatinine (SCr) and calculated glomerular filtration rate improved on MMF monotherapy. This improvement was significant when compared with patients who remained on CNI-based therapy. Improvement was most pronounced in patients with milder renal dysfunction (SCr <2.2 mg/dL prior to conversion) (n = 14) with decrease in SCr from 1.63 ± 0.29 to 1.34 ± 0.26 mg/dL (p = 0.02) at last follow-up. Five patients on MMF monotherapy (21.7%) progressed to end-stage renal disease (ESRD), while only two (8.7%) had rejection episodes following conversion. Clinical markers of CNI-related comorbidities also improved. MMF monotherapy was well tolerated. CONCLUSION: In summary, our data support the safety and efficacy of CNI to MMF monotherapy conversion.

RESUMO

In the current Model for End-Stage Liver Disease allocation system, patients are at risk of suffering repeated episodes of hepatic encephalopathy (HE) while waiting for an orthotopic liver transplantation (OLT); the posttransplantation impact of these episodes has not been well explored. We evaluated the cognitive function and quality of life in a group of OLT recipients (n = 25) who had suffered from overt HE prior to their procedure (HE-PreLT group) and compared their performance to that of a similar group of patients (n = 14) without overt HE (No HE-PreLT group) as well as to controls. Patients were selected from a cohort of 280 patients who underwent OLT during this period; the presence of clinical confounders excluded many of the remaining subjects. Demographic and clinical characteristics were balanced among groups. At an average of 18 months after OLT, we administered 2 neuropsychological batteries [Psychometric Hepatic Encephalopathy Score (PHES) test battery and Repeatable Battery for the Assessment of Neuropsychological Status (RBANS)]; a pyschophysiological test (critical flicker frequency); and the SF-36 quality of life score. The HE-PreLT group scored below controls in 5 of 6 cognitive domains tested by RBANS, 3 of 6 PHES subtests, as well as the critical flicker frequency test. The No HE-PreLT group scored below the controls in 1 of the 6 cognitive domains tested by RBANS. The more severe neurocognitive abnormalities seen in the HE-PreLT group did not appear to affect quality of life, as lower values than normative data were only found in 1 of the 8 SF-36 scales. In conclusion, neurocognitive abnormalities were more severe in liver transplant recipients that had suffered from overt HE prior to OLT. Prospective studies of neurocognitive function pre-OLT and post-OLT are needed to fully determine the impact of such abnormalities.

RESUMO

Alkaline phosphatase, gamma-glutamyl transferase, and 5' nucleotidase are the most common enzymes used in the evaluation of cholestasis. The present knowledge of these enzymes including their function, activity measurement, biologic variables of enzyme activity in healthy persons and disease states, and clinical significance are reviewed. Usefulness of enzymes patterns for diagnosis of specific cholestatic disorders and future directions in evaluation of cholestasis are also discussed.
