RESUMEN
Cytomegalovirus (CMV) infections remain a common problem after solid-organ transplantation. We characterized the burden of CMV infections, and adverse events of CMV prophylaxis after simultaneous pancreas-kidney transplantation (SPK). We included all SPK patients (n = 236) since 2010 in our country. Immunosuppression was ATG, tacrolimus, mycophenolate, and steroids. Valganciclovir prophylaxis was given to all CMV D+/R- patients for six months, and to seropositive SPK patients for three months since February 2019. CMV DNAemia was monitored with quantitative PCR from plasma. Among D+/R- SPK recipients, post prophylaxis CMV infection was detected in 41/60 (68%) during follow-up. In seropositive SPK recipients with no prophylaxis, CMV infection was detected in 53/95 (56%), vs. 28/78 (36%) in those who received 3 months of prophylaxis (P = 0.01). CMV was symptomatic in 35 (15%) patients, of which 10 required hospitalization. Mean duration of viremia was 28 days (IQR 21-41). Leukopenia was detected in 63 (46%) of the 138 patients with valganciclovir prophylaxis. 7/122 (6%) of the CMV infections detected were defined as refractory to treatment, and three patients had confirmed ganciclovir resistance. SPK recipients experience a high burden of CMV infections despite CMV prophylaxis. Leukopenia is common during valganciclovir prophylaxis.
RESUMEN
Background: Antitumoral immune response has a crucial role in constraining cancer. However, previous studies on cholangiocarcinoma (CCA), a rare and aggressive cancer, have reported contradictory findings on the prognostic impact of tumor-infiltrating T-lymphocytes. We aimed to clarify the effect of tumor-infiltrating CD3+ and CD8+ lymphocytes and PD-1/PD-L1 expression on CCA prognosis. Methods: CD3+, CD8+, and PD-1+ lymphocyte densities, as well as PD-L1 expression rate were analyzed from stained tissue microarray samples from the tumor center and invasive margin of 47 cholangiocarcinomas. The association of CD3+ and CD8+ based Immune cell score (ICS) and its components with overall survival was evaluated, adjusting for age, sex, TNM stage, radicality of surgery, tumor location, and PD-L1 expression on immune cells. Results: Low ICS was a strong independent prognostic factor for worse overall survival (Hazard ratio 9.27, 95% confidence interval 2.72-31.64, P<0.001). Among the ICS components, high CD8+ lymphocyte infiltration at the tumor center had the most evident impact on patient outcome. PD-1 and PD-L1 expression on immune cells did not have a significant impact on overall survival alone; however, PD-L1 positivity seemed to impair survival for ICSlow subgroup. Conclusion: Identifying patient subgroups that could benefit from immunotherapy with PD-1/PD-L1 pathway blockade may help improve treatment strategies for this aggressive cancer. Our findings highlight the importance of evaluating the immune contexture in cholangiocarcinoma, as ICS serves as a strong independent prognostic and selective factor for patients who might benefit from immunotherapy.
RESUMEN
BACKGROUND: The use of protocol liver biopsy to monitor liver allograft status remains controversial. There is limited data from modern transplantation populations that includes protocol biopsies to evaluate its value in predicting clinical outcomes. METHODS: All protocol liver biopsies were identified from 875 patients who underwent liver transplantation at Helsinki University Hospital between 2000 and 2019. Each histologic component was analyzed for its ability to predict long-term outcomes, especially graft survival. We determined the frequency of significant biopsy findings based on the Banff working group definition. Liver function tests (LFTs) and clinical markers were evaluated for their ability to predict significant biopsy findings. RESULTS: In total, 867 protocol liver biopsies were analyzed. Significant findings were identified in 20.1% of the biopsies. In the first protocol biopsy, steatohepatitis (hazard ratio [HR] 3.504, p = .03) and moderate or severe congestion (HR 3.338, p = .04) predicted graft loss. The presence of cholangitis (HR 2.563, p = .04), necrosis (HR 7.635, p < .001), mild congestion (HR 4.291, p = .009), and significant biopsy finding (HR 2.540, p = .02) predicted inferior death-censored graft survival. While the degree of elevation of LFTs was positively associated with significant biopsy findings, the discrimination was poor (AUC .572-.622). Combined LFTs and clinical risk factors remained suboptimal for discriminating significant biopsy findings (AUC .696). CONCLUSIONS: Our findings support the use of protocol liver biopsies after liver transplantation since they frequently revealed changes associated with long-term outcomes, even when LFTs were normal.

The primary tumor location (PTL) is associated with the phenotype, metastatic sites, mutations, and outcomes of metastatic colorectal cancer (mCRC) patients, but this has mostly been studied according to sidedness (right vs. left sided). We studied right colon vs. left colon vs. rectal PTL in a real-life study population (n = 1080). Health-related quality of life (HRQoL) was assessed multi-cross-sectionally with QLQ-C30, QLQ-CR29, EQ-5D, and 15D. A chi-square, Kaplan-Meier, and Cox regression were used to compare the groups. The PTL was in the right colon in 310 patients (29%), the left colon in 396 patients (37%), and the rectum in 375 patients (35%). The PTL was associated with distinct differences in metastatic sites during the disease trajectory. The resectability, conversion, and resection rates were lowest in the right colon, followed by the rectum, and were highest in the left colon. Overall survival was shortest for right colon compared with left colon or rectal PTL (median 21 vs. 35 vs. 36 months), with the same trends after metastasectomy or systemic therapy only. PTL also remained statistically significant in a multivariable model. The distribution of symptoms varied according to PTL, especially between the right colon (with general symptoms of metastases) and rectal PTL (with sexual- and bowel-related symptoms). mCRC, according to PTL, behaves differently regarding metastatic sites, resectability of the metastases, outcomes of treatment, and HRQoL.
RESUMEN
BACKGROUND: Biliary dysplasia, a precursor of cholangiocarcinoma (CCA), is a common complication of primary sclerosing cholangitis. Patients with high-grade dysplasia (HGD) or early CCA who have received oncological treatment are candidates for liver transplantation. The preoperative diagnosis of CCA or HGD is challenging, and the sensitivity of biliary brush cytology (BC) is limited. METHODS: By using next-generation sequencing (NGS), we retrospectively analyzed archived tissue samples (n=62) obtained from explanted liver tissue and CCA samples to identify oncogenic mutations that occur during primary sclerosing cholangitis carcinogenesis. BC samples were prospectively collected from patients with primary sclerosing cholangitis (n=97) referred for endoscopic retrograde cholangiography to measure the diagnostic utility of NGS combined with BC compared with traditional cytology alone. RESULTS: Mutations in KRAS, GNAS, FLT3, RNF43, TP53, ATRX, and SMAD4 were detected in archived CCA or HGD samples. KRAS, GNAS, TP53, CDKN2A, FBXW7, BRAF, and ATM mutations were detected in prospectively collected brush samples from patients with histologically verified CCA or HGD. One patient with low-grade dysplasia in the explanted liver had KRAS and GNAS mutations in brush sample. No mutations were observed in brush samples or archived tissues in liver transplantation cases without biliary neoplasia. While KRAS mutations are common in biliary neoplasms, they were also observed in patients without biliary neoplasia during surveillance. CONCLUSIONS: In summary, NGS of BC samples increased the sensitivity of detecting biliary neoplasia compared with traditional cytology. Performing NGS on BC samples may help diagnose HGD or early CCA, benefiting the timing of liver transplantation.

BACKGROUND The use of ABO-incompatible liver transplants (ABO-ILTs) from deceased donors has become more common due to the shortage of available donor livers and increased transplant waiting times. This retrospective study from a national transplant center at Helsinki University Hospital, Finland, aimed to assess the long-term outcomes of ABO-incompatible deceased donor pediatric liver transplants between 1987 and 2022. MATERIAL AND METHODS Sixteen (9.5%) of the 169 pediatric liver transplantations were ABO-ILTs. The median age at transplantation was 5.0 (0.5-15.4) years. Reasons for ABO-ILTs were acute liver failure (18.75%), malignancy (12.5%), small body size and long waiting time (25%), and other reasons (43.75%). The median post-transplant follow-up time was 147 (0.72-353) months. Patient and graft survival and occurrence of surgical complications were compared to ABO-identical transplants, and anti-ABO antibody titers were analyzed. RESULTS The 1-, 3-, and 5-year patient survivals were comparable between the ABO-I and ABO-compatible groups, being 81.3%, 73.9%, and 73.9% (ABO-I) and 87.5%, 82.5%, 77.9% (ABO-compatible), respectively. Three patients with ABO-ILTs died of sepsis and multiorgan failure during the first 3 months after transplantation. The occurrence of biliary complications and early vascular thrombosis (<30 days after transplantation) did not differ significantly between recipients with an ABO-ILT vs ABO-compatible liver graft. CONCLUSIONS The findings from this study support findings from previous studies that outcomes after ABO-incompatible liver transplants in children were comparable to outcomes from ABO-identical liver transplants.

BACKGROUND AND AIMS: Management of Budd-Chiari syndrome (BCS) has improved over the last decades. The main aim was to evaluate the contemporary post-liver transplant (post-LT) outcomes in Europe. APPROACH AND RESULTS: Data from all patients who underwent transplantation from 1976 to 2020 was obtained from the European Liver Transplant Registry (ELTR). Patients < 16 years, with secondary BCS or HCC were excluded. Patient survival (PS) and graft survival (GS) before and after 2000 were compared. Multivariate Cox regression analysis identified predictors of PS and GS after 2000. Supplemental data was requested from all ELTR-affiliated centers and received from 44. In all, 808 patients underwent transplantation between 2000 and 2020. One-, 5- and 10-year PS was 84%, 77%, and 68%, and GS was 79%, 70%, and 62%, respectively. Both significantly improved compared to outcomes before 2000 ( p < 0.001). Median follow-up was 50 months and retransplantation rate was 12%. Recipient age (aHR:1.04,95%CI:1.02-1.06) and MELD score (aHR:1.04,95%CI:1.01-1.06), especially above 30, were associated with worse PS, while male sex had better outcomes (aHR:0.63,95%CI:0.41-0.96). Donor age was associated with worse PS (aHR:1.01,95%CI:1.00-1.03) and GS (aHR:1.02,95%CI:1.01-1.03). In 353 patients (44%) with supplemental data, 33% had myeloproliferative neoplasm, 20% underwent TIPS pre-LT, and 85% used anticoagulation post-LT. Post-LT anticoagulation was associated with improved PS (aHR:0.29,95%CI:0.16-0.54) and GS (aHR:0.48,95%CI:0.29-0.81). Hepatic artery thrombosis and portal vein thrombosis (PVT) occurred in 9% and 7%, while recurrent BCS was rare (3%). CONCLUSIONS: LT for BCS results in excellent patient- and graft-survival. Older recipient or donor age and higher MELD are associated with poorer outcomes, while long-term anticoagulation improves both patient and graft outcomes.

BACKGROUND & AIMS: There is controversy regarding the optimal calcineurin inhibitor type after liver transplant(ation) (LT) for primary sclerosing cholangitis (PSC). We compared tacrolimus with cyclosporine in a propensity score-matched intention-to-treat analysis based on registries representing nearly all LTs in Europe and the US. METHODS: From the European Liver Transplant Registry (ELTR) and Scientific Registry of Transplant Recipients (SRTR), we included adult patients with PSC undergoing a primary LT between 2000-2020. Patients initially treated with cyclosporine were propensity score-matched 1:3 with those initially treated with tacrolimus. The primary outcomes were patient and graft survival rates. RESULTS: The propensity score-matched sample comprised 399 cyclosporine-treated and 1,197 tacrolimus-treated patients with PSC. During a median follow-up of 7.4 years (IQR 2.3-12.8, 12,579.2 person-years), there were 480 deaths and 231 re-LTs. The initial tacrolimus treatment was superior to cyclosporine in terms of patient and graft survival, with 10-year patient survival estimates of 72.8% for tacrolimus and 65.2% for cyclosporine (p <0.001) and 10-year graft survival estimates of 62.4% and 53.8% (p <0.001), respectively. These findings were consistent in the subgroups according to age, sex, registry (ELTR vs. SRTR), time period of LT, MELD score, and diabetes status. The acute rejection rates were similar between groups. In the multivariable Cox regression analysis, tacrolimus (hazard ratio 0.72, p <0.001) and mycophenolate use (hazard ratio 0.82, p = 0.03) were associated with a reduced risk of graft loss or death, whereas steroid use was not significant. CONCLUSIONS: Tacrolimus is associated with better patient and graft survival rates than cyclosporine and should be the standard calcineurin inhibitor used after LT for patients with PSC. IMPACT AND IMPLICATIONS: The optimal calcineurin inhibitor to use after liver transplantation in patients with primary sclerosing cholangitis has yet to be firmly established. Since randomized trials with long follow-up are unlikely to be performed, multicontinental long-term registry data are essential in informing clinical practices. Our study supports the practice of using tacrolimus instead of cyclosporine in the initial immunosuppressive regimen after liver transplantation for patients with primary sclerosing cholangitis. The retrospective registry-based design is a limitation.

BACKGROUND: Kidney disease is common after liver transplantation (LT), but postoperative kidney failure is difficult to predict. Current guidelines recommend simultaneous liver-kidney transplantation (SLKT) in patients with pre-LT estimated glomerular filtration rate (eGFR) below 30-40 mL/min, which might be too liberal. The aim of this study was to evaluate the risk of kidney failure after LT. We also assessed the predictive ability of pretransplantation eGFR using various equations. METHODS: This single-center study included patients undergoing primary LT 2006-2020. Patients undergoing simultaneous liver-kidney transplantations or on dialysis before LT were analysed separately. We calculated 5 different eGFR equations measured just before LT and assessed their predictive ability using Kaplan-Meier cumulative incidence estimates. RESULTS: Among 556 LT patients with a median follow-up of 5.0 years (IQR 2.0-8.5), 20 developed kidney failure during follow-up, 7 of them within 1-year post LT. Six of these 7 suffered from major perioperative complications. Depending on the eGFR equation used, the incidence of kidney failure within 1-year was 3.9-6.7% at pre-LT eGFR-values <30 mL/min, 1.2-3.1% at eGFR 30-60 mL/min, and 0.6-0.9% at eGFR >60 mL/min. CONCLUSIONS: Kidney failure within 1-year post-LT could not be reliably predicted by pre-LT eGFR. However, kidney failure was uncommon even in patients with severely reduced pre-LT glomerular filtration rate (eGFR <30 mL/min), and extremely rare in patients unaffected by major perioperative complications. Our data prompts further consideration regarding the guidelines for SLKT in patients with a reduced preoperative eGFR.

Oral disease is linked with systemic inflammation and various systemic conditions, including chronic liver disease. Liver transplantation (LT) candidates often need dental infection focus eradication, and after LT, there is high risk of many inflammation-related complications. We studied whether pre-LT dental status is associated with the occurrence of post-LT complications. This study included 225 adult LT recipients whose teeth were examined and treated before LT, and 40 adult LT recipients who did not have pre-LT dental data available. Data on post-LT complications were collected from the national liver transplant registry and followed up until the end of July 2020. Worse pre-LT dental status was associated with a higher risk of acute rejection post-LT compared to patients with good dental status. Worse dental status was also associated with higher 1-year-post-LT ALT levels and lower albumin levels. In conclusion, poor pre-LT oral health seems to associate with an increased risk of post-LT acute rejection and with elevated ALT levels and decreased albumin levels, suggesting an effect on post-LT liver health. Therefore, prevention and treatment of oral and dental diseases should be promoted early in the course of liver disease.
RESUMEN
In elective pancreatic surgery, somatostatin-analogues pasireotide and octreotide are variably used to reduce postoperative complications, but knowledge on their role in pancreas transplantation is limited. This study compared pasireotide and octreotide for their association with complications after simultaneous pancreas-kidney transplantation (SPK). This retrospective study included consecutive patients undergoing SPK's from July 2013 to July 2022. Between July 2013 and April 2020, octreotide was administered 0.1 mg s.c. once daily and between May 2020 and July 2022 pasireotide was administered 0.9 mg twice daily, both until third postoperative day. Complications within 90 days postoperatively were collected, and reoperation rate and Comprehensive Complication index (CCI) ≥ 33.7 (morbidity equal to one reoperation) were used as primary outcomes. Of the 213 patients undergoing SPK, 150 patients received octreotide and 63 pasireotide. Baseline characteristics were comparable. Reoperation rate was 25.3% (n = 38) and 17.5% (n = 11) (p = 0.213) and rate of CCI ≥ 33.7 was 40.7% (n = 61) and 30.2% (n = 19) (p = 0.148) in octreotide and pasireotide groups, respectively. When adjusted with donor BMI, pancreas donor risk index, and donor sex, receiving pasireotide translated into OR 0.49 (95% CI: 0.25-0.96 p = 0.037) for CCI ≥ 33.7. Pasireotide was independently associated with lower postoperative morbidity within 90 days of SPK compared to octreotide.

BACKGROUND AND OBJECTIVE: Gallbladder cancer (GBC) is a rare malignancy in the Nordic countries and no common Nordic treatment guidelines exist. This study aimed to characterize the current diagnostic and treatment strategies in the Nordic countries and disclose differences in these strategies. METHODS: This was a survey study with a cross-sectional questionnaire of all 19 university hospitals providing curative-intent surgery for GBC in Sweden, Norway, Denmark, and Finland. RESULTS: In all Nordic countries except Sweden, neoadjuvant/downstaging chemotherapy was used in GBC patients. In T1b and T2, majority of the centers (15-18/19) performed extended cholecystectomy. In T3, majority of the centers (13/19) performed cholecystectomy with resection of segments 4b and 5. In T4, majority of the centers (12-14/19) chose palliative/oncological care. The centers in Sweden extended lymphadenectomy beyond the hepatoduodenal ligament, whereas all other Nordic centers usually limited lymphadenectomy to the hepatoduodenal ligament. All Nordic centers except those in Norway used adjuvant chemotherapy routinely for GBC. There were no major differences between the Nordic centers in diagnostics and follow-up. CONCLUSIONS: The surgical and oncological treatment strategies of GBC vary considerably between the Nordic centers and countries.

Older adults are underrepresented in metastatic colorectal cancer (mCRC) studies and thus may not receive optimal treatment, especially not metastasectomies. The prospective Finnish real-life RAXO-study included 1086 any organ mCRC patients. We assessed repeated centralized resectability, overall survival (OS), and quality of life (QoL) using 15D and EORTC QLQ-C30/CR29. Older adults (>75 years; n = 181, 17%) had worse ECOG performance status than adults (<75 years, n = 905, 83%), and their metastases were less likely upfront resectable. The local hospitals underestimated resectability in 48% of older adults and in 34% of adults compared with the centralized multidisciplinary team (MDT) evaluation (p < 0.001). The older adults compared with adults were less likely to undergo curative-intent R0/1-resection (19% vs. 32%), but when resection was achieved, OS was not significantly different (HR 1.54 [CI 95% 0.9-2.6]; 5-year OS-rate 58% vs. 67%). 'Systemic therapy only' patients had no age-related survival differences. QoL was similar in older adults and adults during curative treatment phase (15D 0.882-0.959/0.872-0.907 [scale 0-1]; GHS 62-94/68-79 [scale 0-100], respectively). Complete curative-intent resection of mCRC leads to excellent survival and QoL even in older adults. Older adults with mCRC should be actively evaluated by a specialized MDT and offered surgical or local ablative treatment whenever possible.
RESUMEN
INTRODUCTION: Simultaneous pancreas-kidney transplantation (SPK) is an option for patients with type 1 diabetes (T1D) and kidney failure but can be associated with a high complication rate. Here we describe our 10-year experience since the launch of the SPK program. METHODS: This retrospective study included consecutive patients with T1D receiving SPK from March 14, 2010 to March 14, 2020 at Helsinki University Hospital. Portocaval anastomosis (i.e., systemic venous drainage) and enteric exocrine drainage were used. A specific team was trained for both pancreas retrieval and transplantation, postoperative care was standardized to include somatostatin analogues, antimicrobial treatment, and preoperatively initiated chemothrombopropylaxis. During program maturation donor criteria were expanded and logistical processes improved to minimize cold ischemia time. Clinical data were collected from a nationwide transplantation registry and patient records. RESULTS: A total of 166 SPKs were performed (median 2 per year in the first 3 years, 17.5 per year for the following 4 years, and 23 per year for the past 3 years). Seven patients (4.1%) died with a functioning graft with a median 43 months follow-up. One-year pancreas graft survival was 97.0%, 3-year pancreas graft survival was 96.1% and 5-year was 96.1%. Mean HbA1c was 36 mmol/mol (SD 5.57) and creatinine was 107 µmol/L (SD 34.69) at 1-year after transplantation. All kidney grafts were functioning at the end of follow-up. Complications required re-laparotomy in 39 (23%) patients, mostly due to a pancreas graft related problem (N = 28). No pancreas or kidney graft failure from thrombosis occurred. CONCLUSION: A planned, step-wise development of an SPK program offers a safe and effective treatment for patients with T1D and kidney failure.

OBJECTIVES: Alcohol-related liver disease (ALD) is among the most common indications for liver transplantation (LTX) in Europe and North America, with good five-year survival rates post-LTX. Here we evaluated survival up to and beyond 20 years after LTX for patients with ALD compared to a comparison group. METHODS: Patients with ALD and a comparison group transplanted in the Nordic countries between 1982 and 2020 were included. Data were analyzed using descriptive statistics, Kaplan-Meier curves and predictors of survival were assessed with Cox-regressions. RESULTS: 831 patients with ALD and 2979 patients in the comparison group were included in the study. Patients with ALD were older at the time of LTX (p < .001) and more likely to be male (p < .001). The estimated median follow-up time was 9.1 years for the ALD-group and 11.1 years for the comparison group. 333 (40.1%) patients with ALD and 1010 (33.9%) patients in the comparison group died during follow-up. The overall survival was impaired for patients with ALD compared to the comparison group (p < .001) and was evident for male and female patients, patients transplanted before and after 2005, and observed in all age-groups except patients over 60 years. Age at transplant, waiting time, year of LTX and country of LTX were associated with decreased survival after LTX for patients with ALD. CONCLUSIONS: Patients with ALD have a decreased long-term survival following LTX. This difference was evident in most sub-groups of patients and warrants close follow-up of liver transplanted patients with ALD with focus on risk reduction.

Several perioperative scoring systems have been created to predict outcomes in metastatic colorectal cancer; however, these rarely include histological parameters. We evaluated histological factors used for patients with liver metastases operated between 2000 and 2019 and compared the results with the Fong score. Many scoring models for overall disease-free survival (DFS) were established and compared using multivariate Cox proportional hazard models. Statistically significant predictors at a 5% level in the univariate analysis were included in the multivariate models using the backward and forward selection methods. Per these models, we established a score of eight histological factors. We defined low-, intermediate-, and high-risk groups and compared them using the Kaplan-Meier survival and receiver operating characteristics (ROC) analyses. The histological score's accuracy was compared with the modified Fong clinical risk score. The following factors constituted the Helsinki score: advanced pT stage, node-positive primary, ≥2 metastases, size >50 mm, vitality >30%, margin <5 mm, vascular invasion and biliary invasion. The high-risk group had significantly worse DFS and overall survival. In ROC analyses, the Helsinki score was slightly better than the modified Fong clinical risk score. Helsinki score challenges physicians to acknowledge histological factors as important outcome measures.

OBJECTIVE: The objective of this study was to investigate the short-term and long-term morbidity after liver transplantation (LTx) in patients with primary sclerosing cholangitis (PSC). BACKGROUND: PSC is a common indication for LTx in Scandinavia. Recently, research has focused on long-term survival and morbidity. The Comprehensive Complication Index (CCI) precisely describes postsurgical complications, by considering both number and severity. PATIENTS AND METHODS: Two patient groups were compared: those with classical PSC symptoms (n=148) and those with increased risk of cholangiocarcinoma (n=51, premalignant group). Two CCI scores were calculated, at 1-year post-LTx and a cumulative overall score at the latest follow-up. In addition, we investigated factors potentially related to high CCI. RESULTS: The 1-year median CCI were 29.6 and 26.2 in the classical and premalignant groups, respectively ( P =0.308). The median overall CCI were 43.2 and 46.8 ( P =0.765), respectively. Patient survival was significantly lower in patients with 1-year CCI>42. The most common complications associated with low survival were cholangitis, infections, and hypertension. One-year and overall CCI were similar between sexes and different types of biliary anastomosis. Patients with pre-LTx Model for End-stage Liver Disease scores >20 had higher 1-year and overall CCI (36.2 and 52.6, respectively) than those with lower Model for End-stage Liver Disease scores. Both low (<22) and high (>25 kg/m 2 ) body mass indices were associated with high overall 1-year and overall CCI (50.9 and 41.8, respectively), but median body mass indices were associated with significantly lower 1-year and overall CCI (38.4, P =0.023). CONCLUSIONS: The previously determined 1-year CCI cutoff of 42 could significantly predict survival post-LTx. Mortality and morbidity were not significantly different between the PSC groups analyzed.
