Polycystic Liver Disease Registry (UK)

Map the natural course of PLD

To establish the demographics, presence and severity of symptoms (quantified using the validated PLD-Q questionnaire), liver cyst characteristics on imaging (assessed using Qian's classification), biochemical marker abnormalities (including gamma-glutamyl transferase and alkaline phosphatase), rate and nature of complications, need for treatment, change in liver volume in patients with PLD. This data will be collected retrospectively and prospectively from clinical records and the PLD-Q questionnaire.

Assess quality of life using the validated PLD questionnaire (PLD-Q)

The PLD-Q questionnaire consists of 18 items assessing symptom frequency and severity. It gives a score (0-100) based on the patient's answers with a higher score indicating more severe, symptomatic disease with a poorer quality of life.

Elucidate risk factors for developing a complication in PLD

For patients that develop a complication of PLD (including jaundice, abdominal hernia, features of portal hypertension, cyst haemorrhage and cyst infection) we will look through their clinical record to establish if there any risk factors which are common to those with a complication (e.g. age, gender, medications, cyst phenotype).

Elucidate elements that affect PLD progression

For patients that have a worsening of their PLD (based on increasing symptoms as per the PLD-Q questionnaire, development of complications or need for treatment) we will look through their clinical records to establish if there any elements which are common to those with progressive disease (e.g. age, gender, medications).

Compare effectiveness of different therapies

For patients who have had or require treatment for PLD we will compare the effectiveness of that treatment based on change in symptoms (based on PLD-Q questionnaire), recurrence of symptoms, development of complications or need for further treatment.
