Sklerosierende Cholangitiden: Primäre, autoimmune und sekundäre Erkrankungen

Secondary sclerosing cholangitis in critically ill patients has a poor outcome but lower tumour incidence than primary sclerosing cholangitis

BACKGROUND

Secondary sclerosing cholangitis in critically ill patients (SSC-CIP) is an emerging disease with grim prognosis.

OBJECTIVE

Our aim was the analysis of prognostic factors, long-term outcome and risk of tumour development in SSC-CIP compared with primary sclerosing cholangitis (PSC) patients.

METHODS

Retrospective analysis between 2008 and 2018.

RESULTS

One hundred and eleven patients with SSC-CIP and 408 PSC patients were identified. Median orthotopic liver transplantation (OLT)-free survival was 16 months for SSC-CIP and 147 months for PSC (p < 0.001). OLT was performed in 18/111 SSC-CIP compared with 166/408 PSC patients (p < 0.001). Malignant tumours were detected in 17.9% of PSC patients (73/408) compared with 2.7% (3/111) in SSC-CIP (p < 0.001). In multivariate Cox regression analysis low levels of C-reactive protein (hazard ratio 4.687 (95% confidence interval (CI) 1.144-19.199, p = 0.032) were significantly associated with a prolonged survival whereas higher age (hazard ratio 0.488 (95% CI 0.23-1.038), p = 0.062) showed a trend for shorter survival in SSC-CIP. For PSC malignancies (hazard ratio 0.42 (95% CI 0.313-0.575), p < 0.001) and higher age (hazard ratio 0.709 (95% CI 0.544-0.922), p = 0.01) were associated with a shorter OLT-free survival.

CONCLUSION

SSC-CIP is characterized by acute onset of liver disease and poor prognosis but with lower tumour incidence compared with PSC.

Liver transplantation for critically Ill patients with secondary sclerosing cholangitis: Outcome and complications

Secondary sclerosing cholangitis in critically ill patients (SSC-CIP) is a destructive cholangiopathy with a poor prognosis. Liver transplantation (LT) is an established therapeutic option in end-stage liver disease but is insufficiently evaluated in patients with SSC-CIP. Our aim was the retrospective analysis of the outcome and complications of patients with SSC-CIP undergoing LT between 2002 and 2012. Demographic characteristics, laboratory, transplantation, and follow-up data were compared to sex- and age-matched patients undergoing LT because of other reasons. Quality of life (QoL) before and after LT was assessed in a retrospective telephone interview. LT was performed in 21 patients with SSC-CIP. The main causes for intensive care unit admission comprised cardiothoracic surgery interventions (10/21, 48%), polytrauma (6/21, 29%), and pneumonia (3/21, 14%). Median follow-up period after LT was 82 months (interquartile range [IQR], 37-129) for patients with SSC-CIP and 83 months (IQR, 55-104) for control patients. Biopsy-proven rejection episodes in patients with SSC-CIP (4/21, 19%) were similar compared to control patients (12/60, 20%; P = 0.93). Cytomegalovirus infections were equal in both groups (10/21, 48% versus 25/60, 42%; P = 0.64). The 1-, 3-, and 5-year survival rates of patients with SSC-CIP versus control patients were 100% versus 98%, 86% versus 92%, and 76% versus 87%, respectively (P > 0.05). The QoL improved significantly after LT in SSC-CIP. In conclusion, LT is a valid option for patients with SSC-CIP with excellent long-term outcome and improvement of QoL.
