Severe itching in PFIC children disrupts sleep, family life: Registry analysis
Disease also creates severe financial burden related to medical expenses
Written by |
Among children and adolescents with progressive familial intrahepatic cholestasis (PFIC), severe itch significantly affects sleep, overall perceptions of health, and the family’s quality of life, according to an analysis of the PFIC Network Patient Registry (PNPR).
PFIC families also face a severe financial burden, caused by out-of-pocket expenses for medical care, difficulties paying bills, and having to adjust careers, data showed.
“The PNPR fills a previously identified gap in PFIC research — the lack of [patient-reported outcomes] — and reveals the negative impact of disease and [itch] on patient and family function, [quality of life] indicators, finances, and measures of general health,” the scientists wrote.
The findings were described in the study “Baseline analysis of patient reported outcomes in the progressive familial intrahepatic cholestasis patient registry,” which was published in the Journal of Pediatric Gastroenterology and Nutrition.
Registry focused on patient-reported outcomes
Cholestasis refers to the slowing or complete stoppage of the flow of bile, a digestive fluid, from the liver to the intestines. As bile builds up, it can damage the liver and may progress to irreversible liver scarring (cirrhosis) and liver failure, when a liver transplant becomes the only therapeutic option.
Bile accumulation in a damaged liver can also cause bile to leak into the bloodstream, leading to symptoms such as itching (pruritus).
PFIC, which usually manifests during infancy or childhood, is a group of genetic disorders that cause cholestasis inside the liver, with each type caused by mutations in different genes.
“The rare nature of the PFIC spectrum of diseases makes large, population research difficult, and the majority of published reports emanate from single-center experiences, often with limited data regarding natural history,” the researchers wrote.
More recently, large multicenter registries have been initiated to collect data on PFIC. While these traditional registries have focused on PFIC outcomes such as survival without the need for liver transplant and correlations between genetic mutations and clinical presentation, data on the experiences of patients and their families are missing.
To address this knowledge gap, the PFIC Network launched the patient registry, a global study designed by patients and families to collect meaningful patient-reported outcomes (PROs). Questionnaires are completed by patients (or a parent) to self-report their health status.
“PROs reflect the patients’ perceptions of their status, their perspective on health and disease, and are more reflective of underlying health status than physician reporting,” the team wrote.
Severe itch linked to worse overall health ratings
In this study, a team of researchers at PFIC Network and several U.S. hospitals analyzed PRO data from the PNPR at baseline, representing the initial patient data collected upon registry enrollment.
PROs relevant to PFIC covered diagnosis, symptoms, surgeries, medications, validated measures of itch, sleep, general health, disease impact on family quality of life, and the financial burden of the disease.
As of July 2025, 161 children, adolescents, and adults have enrolled in the PNPR across six continents, including Australia/New Zealand, Africa, Asia, Europe, North America, and South America. A total of 119 were children and adolescents, ages 0-18, meaning that “73.9% of the enrollment data are parent-reports while 26.1% are self-reports,” the team wrote.
The most common diagnosis was PFIC type 2, followed by types 1 and 3. Several participants had an unknown or missing diagnosis.
Parent-reported data from children and adolescents showed that higher itch severity was significantly associated with greater sleep disturbance and sleep impairment. That is, as itching worsens, patients are much more likely to struggle with falling or staying asleep. More severe itch was also significantly linked to lower family quality of life and worse overall health ratings.
Pediatric patients with little or no itch, whether due to a liver transplant, medications, or patient characteristics, had better sleep and improved family well-being.
This baseline analysis shows that pruritus and sleep disturbances significantly impact quality of life and global impressions of health across PFIC subtypes and that the financial burden of disease on families is profound.
Surgery also appeared to make a difference. A total of 43 participants had undergone procedures such as biliary diversion (to redirect bile flow), ileal exclusion (to bypass bile reabsorption in the intestines), and/or liver transplant, while 95 had not. Statistical analysis showed that those who underwent surgery had significantly less severe itch.
Beyond health effects, the condition placed a substantial financial strain on families. When researchers compared 90 registry families (including 36 in the U.S.) with U.S. data from the 2022-2023 National Survey of Children’s Health, notable differences emerged.
PFIC families were more likely to report paying more than $5,000 per year out of pocket for medical care (13.3% vs. 2.9%) and having difficulties paying bills (28.9% vs. 9.2%) than families in the U.S. general population.
Nearly half (45.6%) of PFIC families said they had to adjust their careers — such as quitting or changing jobs, or turning down work — compared with 11.2% of those in the general population.
Finally, more PFIC families spent one to four hours per week providing home health care for their child (34.4% vs. 23.9%) and arranging or coordinating health or medical care (33.3% vs. 23.5%) than the U.S. population.
“This baseline analysis shows that pruritus and sleep disturbances significantly impact quality of life and global impressions of health across PFIC subtypes and that the financial burden of disease on families is profound,” the researchers concluded.
