- Background: Chronic liver disease (CLD) is associated with muscle wasting, reduced exercise tolerance and aerobic capacity (AC). Measures of AC determined using cardiopulmonary exercise testing (CPET) may predict post liver transplant (LT) survival, but relation to non-transplant outcome is uncertain. In patients assessed for LT we examined the relation of CPET AC parameters to severity of liver disease, nutritional state and survival with and without LT.Patients and Methods:Patients assessed for elective first LT for who underwent CPET and anthropometric assessment at a single centre were studied. CPET-derived measures of AC evaluated were peak oxygen consumption (VO2 -peak) and Anaerobic Threshold (AT).Results:399 patients underwent CPET and 223 LT; 45% of patients had VO2 -peak <50% predicted and 31% AT<9ml/kg/min. VO2 -peak and AT correlated with MELD but more closely with serum sodium and albumin. Hand grip strength correlated strongly with VO2 -peak. Patients with impaired AC had prolonged post-LT hospitalisation and 1-year post-transplantation non-survivors had lower AT than survivors (p<0.05), significant on multivariate analysis. 176 patients did not undergo LT; 1-year mortality was 34.6%. AT (p<0.05) and VO2 -peak (p<0.001) were lower in non-survivors. On multivariate analysis, AT was independently associated with non-survival.Conclusions:Aerobic capacity is markedly impaired in many patients with CLD. In those not transplanted, impaired AT was predictive of mortality and in those undergoing LT related to post-operative hospitalisation and survival. AC should be evaluated as a modifiable factor to improve patient survival, whether or not LT is anticipated.

- In patients with familial amyloidotic polyneuropathy (FAP), heart complications are prognostic factors for mortality and morbidity after liver transplantation (LT). However, only a few studies have analyzed the development of arrhythmia in transplant patients with FAP. We investigated the development of arrhythmia requiring pacemaker insertion (PMI) in Swedish transplant patients with FAP, and we related the findings to gender, age at disease onset, and survival. One hundred four transplant patients with the amyloidogenic transthyretin Val30Met mutation were included in the study. Twenty-six (25%) received a pacemaker during the observation period (a median of 11 years after disease onset). This frequency was comparable to that noted in a previous study describing the natural course of FAP. No significant differences in PMI between early-onset cases (<50 years old) and late-onset cases (≥ 50 years old) or between genders were observed. PMI was not significantly related to patient survival. Our study confirms our previously reported short-time observation: LT does not prevent the development of heart arrhythmia necessitating PMI. The development of arrhythmia is unrelated to gender or age at disease onset, and the yearly risk does not appear to decrease with time after LT.

- The principal aim of this study was to compare the probability of and potential risk factors for death and graft loss after primary adult and pediatric liver transplantation in patients undergoing transplantation for autoimmune hepatitis (AIH) to those in patients undergoing transplantation for primary biliary cirrhosis (PBC; used as the reference group) or alcoholic cirrhosis (used as an example of a nonautoimmune liver disease). The 5-year survival of patients undergoing transplantation for AIH (n = 827) was 0.73 [95% confidence interval (CI) = 0.67-0.77]. This was similar to that of patients undergoing transplantation for alcoholic cirrhosis (0.74, 95% CI = 0.72-0.76, n = 6424) but significantly worse than that of patients undergoing transplantation for PBC (0.83, 95% CI = 0.80-0.85, n = 1588). Fatal infectious complications occurred at an increased rate in patients with AIH (hazard ratio = 1.8, P = 0.002 with PBC as the reference). The outcome of pediatric AIH patients was similar to that of adult patients undergoing transplantation up to the age of 50 years. However, the survival of AIH patients undergoing transplantation beyond the age of 50 years (0.61 at 5 years, 95% CI = 0.51-0.70) was significantly reduced in comparison with the survival of young adult AIH patients (0.78 at 18-34 years, 95% CI = 0.70-0.86) and in comparison with the survival of patients of the same age group with PBC or alcoholic cirrhosis. In conclusion, age significantly affects patient survival after liver transplantation for AIH. The increased risk of dying of infectious complications in the early postoperative period, especially above the age of 50 years, should be acknowledged in the management of AIH patients with advanced-stage liver disease who are listed for liver transplantation. It should be noted that not all risk factors relevant to patient and graft survival could be analyzed with the European Liver Transplant Registry database.
