Living with Rare Liver Diseases: Unique challenges, Shared Experiences 

Professor David Jones and Professor Valerie McLin were compensated by Ipsen for their time.  

Rare cholestatic liver diseases are conditions that can impact both children and adults. Three such conditions—Primary Biliary Cholangitis (PBC), Progressive Familial Intrahepatic Cholestasis (PFIC), and Alagille Syndrome (ALGS)—share commonalities yet are unique in their causes, manifestations, and challenges for patients and their families.^{1, 2} Understanding these diseases is crucial for better diagnosis, treatment, and overall care.³ 

PBC is a rare, autoimmune, cholestatic liver disease with increasing prevalence worldwide. In people with PBC, the body attacks and gradually destroys the liver’s small bile ducts.³ If left untreated, bile and toxins may build-up (cholestasis), leading to scarring of the liver (cirrhosis) and eventual liver failure.^4,5,6  

Accumulation of bile may cause liver damage, symptoms like fatigue and intense itching. PBC is often underdiagnosed due to its subtle symptoms, making early recognition and intervention essential for managing the disease.⁷  

PFIC on the other hand, refers to a set of rare genetic conditions where the liver has difficulties releasing bile acid needed to digest fats and oils. The buildup of bile can cause great harm to the liver, potentially leading to liver failure.⁸ Although PFIC can present itself later in life, it generally manifests and is most aggressive in infants and young children.^{9, 10}   

ALGS is an inherited condition that can affect the liver, heart, brain, blood vessels and bones.^{11, 12, 13} Children with these conditions often require nutritional support and face frequent medical visits, impacting their schooling and social development.¹⁴ 

Despite their differences, these diseases share important commonalities. A key symptom across all of them is pruritus (itching), which can be overwhelming, especially in children. ^{15, 16, 17} For people living with these diseases, the itch is far more than a mild irritation; it can be all-consuming, disrupting daily life and causing significant distress. In addition, fatigue is also a symptom that causes great burden particularly for people living these conditions, with many experiencing debilitating tiredness that affects concentration and social interactions.   

Ipsen is committed to raising awareness of rare cholestatic liver diseases and bringing treatment options to people living with these conditions and their families. Advances in medical research are leading to more treatments and more informed symptom management. ¹⁸ However, awareness of these conditions remains low among patient communities and healthcare professionals (HCPs) throughout the world. Increased discussions about symptoms are important to help people living with rare cholestatic liver diseases understand and manage their symptoms and achieve timely diagnosis.   

As we look to the future, a collaborative, patient-centered approach is key to managing these complex diseases.
