The risks of developing energy or nutrient deficits are of great concern in infants and children with the rare lymphoedema cholestasis syndrome 1 (LCS1)/Aagenaes syndrome. In adolescents and adults, it is not known whether LCS1 patients need specific dietary advice outside periods of cholestasis. The primary objective of the present study was to evaluate the progression of the liver disease and nutritional status in patients with LCS1 over a period of nine years. Dietary and biochemical data were obtained for patients and healthy controls in two cross-sectional studies, a baseline (2000) and a follow-up study (2009). Thirteen patients above 18 years of age with LCS1 (65%) were included (six females). Dietary intake and biochemical measures were stable in the patients from baseline until follow-up. Compared to healthy controls, the patients had significantly higher serum levels of alkaline phosphatase (p = .015 and p = .002), gamma-glutamyltransferase (p = .001 and p .001), total bile acids (p = .037 and p = .016), and fibrinogen (p = .046 and p .001) and lower albumin (p = .033 and p .001) and α-tocopherol (p = .011 and p = .003) at baseline and follow-up. Despite stable liver function, the presence of a low grade of hepatobiliary dysfunction in these patients was suggested. Patients with LCS1 had a nutritional status similar to healthy controls, with no clinical deterioration of liver function during the nine-year period. The findings presented in this paper support that more than 50% of patients with LCS1 can expect a normal lifespan.

Objective. To investigate the prognosis of liver disease in Aagenaes syndrome (lymphoedema cholestasis syndrome 1 (LCS1)), which is an autosomal recessive inherited syndrome consisting of neonatal cholestasis with intermittent cholestatic episodes in childhood into adulthood and development of lymphoedema. Forty Norwegian patients are known to have this condition, 25 of whom are alive. A clinical description of the liver disease is supplied with a case-control study. Material and methods. In this paper we review the course of the liver disease in the Norwegian cohort of patients and present results from a case-control study in the patients above 10 years of age. The case-control study was performed on 15 patients without clinical cholestasis (itching and sometimes jaundice) at the time of the study. An evaluation of 11 patients above 15 years of age without chronic biochemical cholestasis (increased alkaline phosphatase (ALP), gammaglutamyl transferase (GGT) and/or serum bile acids) was also carried out. For each patient one randomly identified control person was included (15 in one study, 11 in the other). Results. Cirrhosis with either transplantation or death in infancy or early childhood occurred in six patients; slowly developing cirrhosis occurred in three patients. Two patients may be in the process of developing cirrhosis. Significantly increased ALP and GGT levels were found in patients with normal liver biochemistry in the preceding years when compared with the case control group. Additionally, albumin was found to be lower in older patients. Conclusions. Compared with that for other types of hereditary neonatal cholestasis, patients with LCS1 have a relatively good prognosis. More than 50% can expect a normal life span.
