Abstract
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.

Abstract
BACKGROUND Over a quarter of organ transplant recipients have low immunoglobulin levels in their early post-transplant course, which is associated with increased risk of infection and mortality. Although immunoglobulin level varies by sex among healthy individuals, it is unknown how such differences are affected by transplant-related immunosuppression. This study compared post-liver transplant immunoglobulin G (IgG) between sexes at varying ages. METHODS Serum specimens from a prospective cohort of 130 liver transplant recipients were analyzed. IgG was measured at time of transplant and from one-month post-transplant samples. Post-transplant IgG was compared between sexes using multivariable linear regression. Four age and sex categories were created (women<50, women≥50, men<50, men≥50) and the model repeated with this as the explanatory variable. The relationship between sex hormone concentrations and post-transplant IgG was also explored. Infection type and incidence were examined within groups. RESULTS The cohort included 99 men, 31 women (mean age 53). In adjusted linear regression, post-transplant IgG was not significantly different by sex (p = 0.92). However, when broken into four categories by age and sex, the contrast in IgG levels between younger versus older patients was strikingly greater among women than among men. An interaction term including age and sex was statistically significant (p = 0.03). The combined age-sex categorical variable was also significantly associated with post-transplant IgG (p = 0.01). Finally, an association was identified between baseline estradiol level and post-transplant change in IgG (p = 0.04). CONCLUSIONS Sex and age have an important relationship with post-transplant IgG with older women demonstrating lowest concentrations. Immunoglobulin levels have previously demonstrated association with post-transplant outcomes.

Abstract
BACKGROUND Sex differences in kidney graft loss rates were reported in the United States. Whether these differences are present in other countries is unknown. METHODS We estimated the association between recipient sex and death-censored graft loss in patients of all ages recorded in the Scientific Registry of Transplant Recipients, Australia and New Zealand Dialysis and Transplant Registry, and Collaborative Transplant Study registries who received a first deceased donor kidney transplant (1988-2019). We used multivariable Cox regression models, accounting for the modifying effects of donor sex and recipient age, in each registry separately; results were combined using individual patient data meta-analysis. RESULTS We analyzed 438 585 patients. Young female patients 13-24 y old had the highest crude graft loss rates (female donor: 5.66; male donor: 5.50 per 100 person-years). Among young recipients of male donors, females showed higher graft loss risks than males (0-12 y: adjusted hazard ratio [aHR] 1.42, (95% confidence interval [CI], 1.17-1.73); 13-24 y: 1.24 (1.17-1.32); 25-44 y: 1.09 (1.06-1.13)). When the donor was female, there were no significant differences by recipient sex among those of age <45 y; however, the aHR for females was 0.93 (0.89-0.98) in 45-59 y-old and 0.89 (0.86-0.93) in ≥ 60 y-old recipients. Findings were similar for all 3 registries in most age intervals; statistically significant heterogeneity was seen only among 13-24-y-old recipients of a female donor (I2 = 71.5%, P = 0.03). CONCLUSIONS There is an association between recipient sex and kidney transplantation survival that is modified by recipient age and donor sex.
