RESUMEN

Hepatopulmonary syndrome (HPS) is associated with increased waitlist mortality in liver transplantation (LT) candidates. Children with HPS are granted Model for End-Stage Liver Disease (MELD)/Pediatric End-Stage Liver Disease (PELD) exception points for waitlist prioritization in the United States based on criterion developed for adults. In this study, the impact of this MELD/PELD exception policy on post-LT survival in children was examined. A retrospective cohort of patients aged younger than 18 years with a MELD/PELD exception request who underwent LT between 2007 and 2018 were identified in the Scientific Registry of Transplant Recipients. Patients were stratified by waitlist partial pressure of arterial oxygen (PaO 2 ) to assess risk factors for waitlist mortality and post-LT survival. Among 3082 pediatric LT recipients included in the study, 124 patients (4%) received MELD/PELD exception points for HPS. Patients with HPS were a median age of 9 years (interquartile range: 6, 12 years), 54.8% were girls, and 54% were White. Most patients (87.9%) were listed with laboratory MELD/PELD scores <15. Waitlist mortality for patients with HPS exception points was rare and not different from patients without HPS. When stratified by pre-LT PaO 2 , hypoxemia severity was not associated with differences in 1-, 3-, or 5-year survival rates after LT ( p = 0.13). However, patients with HPS showed a slightly lower survival rate at 5 years compared with patients without HPS (88.7% vs. 93.4%; p = 0.04). MELD/PELD exceptions for children with HPS mitigated waitlist mortality, and recipients with HPS experienced excellent 5-year survival after LT, although slightly lower than in patients without HPS. Unlike adults with HPS, the severity of pre-LT hypoxemia in children does not impact post-LT survival. These data suggest that adult criteria for granting MELD/PELD exception points may not appropriately capture HPS severity in pediatric patients. Further prospective multicenter studies to examine the risk factors predicting negative survival outcomes in children with HPS are warranted.

RESUMEN

Literature on living nondirected liver donation is sparse. The purpose of this study was to assess health-related quality of life (HR-QOL) in anonymous nondirected living liver donors (ND-LLDs). ND-LLDs at 3 centers: University of Alberta (n = 12), University of Colorado (n = 12), and University of Southern California (n = 12), were surveyed. Thirty donors (83%) responded to the Donor Quality of Life (USC DQLS) and Short-Form 36 (SF-36). Most respondents (n = 15, 50%) donated their left lateral segment, 27% right lobe, and 23% left lobe. The majority were female (67%) and mean age was 38.9 ± 11.2 years at donation. Median follow-up was 1.1 (interquartile range 0.4-3.3) years. Approximately 37% had previously donated a kidney. Eleven experienced ≥1 postoperative complication, with only 1 Clavien-Dindo IIIb. Most reported minimal impact on school or work performance, all felt positive or neutral about their overall health since donation, and none expressed postdonation regrets. No donor reported impacts on health insurability, and 3 of 4 respondents attempting to purchase life insurance postdonation were successful. ND-LLD SF-36 outcomes were similar to US population norms. Overall, ND-LLDs demonstrated acceptable HR-QOL after donation and are appropriate candidates for partial liver donation. Based on evaluation of donation impact, consideration should be given to postdonation support strategies.

RESUMEN

BACKGROUND: To assess the impact of living liver donation (LD) in a diverse and aging population up to 20 y after donation, particularly with regard to medical, financial, psychosocial, and overall health-related quality of life (HRQOL). METHODS: Patients undergoing LD between 1999 and 2009 were recruited to respond to the Short-Form 36 and a novel Donor Quality of Life Survey at two time points (2010 and 2018). RESULTS: Sixty-eight living liver donors (LLDs) completed validated surveys, with a mean follow-up of 11.5 ± 5.1 y. Per Donor Quality of Life Survey data, physical activity or strength was not impacted by LD in most patients. All respondents returned to school or employment, and 82.4% reported that LD had no impact on school or work performance. LD did not impact health insurability in 95.6% of donors, and only one patient experienced difficulty obtaining life insurance. Overall, 97.1% of respondents did not regret LD. Short-Form 36 survey-measured outcomes were similar between LLDs and the general U.S. POPULATION: LLDs who responded in both 2010 and 2018 were followed for an overall average of 15.4 ± 2.4 y and HRQOL outcomes in these donors also remained statistically equivalent to U.S. population norms. CONCLUSIONS: This study represents the longest postdonation follow-up and offers unique insight related to HRQOL in a highly diverse patient population. Although LLDs continue to maintain excellent HRQOL outcomes up to 20 y after donation, continued lifetime follow-up is required to accurately provide young, healthy potential donors with an accurate description of the risks that they may incur on aging.

RESUMEN

Anonymous nondirected living liver donation (ANLLD), sometimes referred to as "altruistic" donation, occurs when a biologically unrelated person comes forward to donate a portion of his/her liver to a transplant candidate who is unknown to the donor. Here, we explore the current status of ANLLD with special consideration of published reports; US experience; impact on donor psychosocial outcomes; barriers to donation; and current global trends with respect to ethical considerations. Between 1998 and 2019, 105 anonymous nondirected living liver donor (ND-LLD) transplants have been documented in the US Scientific Registry of Transplant Recipients. Sixteen donors (15%) were reported to experience a postoperative complication. Currently, 89 donors remain alive (85%), 16 (15%) have unknown status, and none are confirmed deceased. Although there are only a handful of case series, these data suggest that ANLLD is a feasible option. While there are no liver-specific data, studies involving anonymous nondirected kidney donors suggest that anonymous donation does not adversely impact psychosocial outcomes in donors or recipients. There are substantial financial burdens and ethical considerations related to ANLLD. Further studies are required to assess donor demographics, psychosocial motivations, long-term health-related quality of life, and financial impact of ANLLD.

RESUMEN

Rapid spontaneous resolution of traumatic acute subdural haematomas (ASDH) can occur but is rare. We present an 88-year-old female who presents with a large left acute subdural haematoma (ASDH) measuring 18 mm in thickness with midline shift of 10.7 mm. We managed her conservatively based upon good consciousness level and absent neurological deficits. Repeat computed tomography (CT) the following day demonstrated near complete resolution of the ASDH and midline shift regression; a further CT confirmed resolution. Most patients with large ASDH require surgical evacuation; however, in rare cases, they can resolve spontaneously with extreme rapidity. Conservative management can be a valid option in carefully selected cases.
