BACKGROUND & AIMS: Polycystic liver disease (PLD) follows a progressive course ultimately leading to severe hepatomegaly and mechanical complaints in a subset of patients. It is still unknown to what extent this compromises health-related quality of life (HRQL). Our aim was to determine HRQL in PLD patients and investigate its association with concurrent abdominal symptoms and liver volume. METHODS: Pooled data of 92 severe PLD patients from two randomized clinical trials were used for our cross-sectional analysis. HRQL was assessed using the generic short-form health survey (SF-36) resulting in eight scale scores and the summarizing physical (PCS) and mental component score (MCS). Subsequently, these were compared with the general population. Abdominal symptoms were measured with a standardized, 7-point scale questionnaire in 54 patients. We dichotomized symptoms for absence or presence and compared them with the component scores. Finally, a possible correlation between liver volume and HRQL was explored. RESULTS: Demographics showed severe polycystic livers (mean 4906 +/- 2315 ml). PCS was significantly lower compared with the general population (P < 0.001), in contrast with a similar MCS (P = 0.82). PLD patients had statistically significant (P < 0.05) diminished physical functioning, role physical, general health, vitality and social functioning scores. Upper- and lower abdominal pain and dyspnoea were significantly associated with a reduced PCS (P < 0.01). No correlation was found between liver volume and HRQL. CONCLUSION: Polycystic liver disease patients had significantly lower HRQL in the physical dimension compared with the general population. Abdominal pain and dyspnoea had a significant impact on this physical dimension of HRQL.
