Beschreibung
Inclusion Criteria:
PBC diagnosis based on meeting 2 of 3 criteria:
- Cholestatic liver biochemistry at disease outset (defined as elevation in the serum ALP level or GGT).
- Associated autoantibody (AMA or PBC-associated antinuclear antibody by immune fluorescence or anti-PDC, anti-Gp210, or anti-Sp100) at a titer of greater than or equal to 1:40.
- Diagnostic or compatible liver biopsy.
- Ability to provide informed consent
- Ability to complete digital questionnaires
- Elevated alkaline phosphatase
- Abbreviations:
alkaline phosphatase [ALP] gamma-glutamyl-transferase [GGT] antimitochondrial antibody [AMA] Primary Biliary Cholangitis [PBC] Plasmacytoid dendritic cells [PDC] glycoprotein 210 [Gp210] Scleroderma 100 [Sp100]
Exclusion Criteria:
- Uncontrolled chronic inflammatory condition that is likely to contribute to symptoms of poor fatigue and sleep and confound results.
- Active malignancy requiring treatment

Change in PBC-40 fatigue domain score in patients with PBC
Zeitfenster: 7 months (1 month screening and 6 months wearing the device)
|
The PBC-40 fatigue domain allows a potential value range of 11 to 55 with higher values denoting worse fatigue.
A score of >33 identifies patients with moderate-severe fatigue and a mean change in this score by 5 points after 3 months has been used in other studies to denote clinically meaningful significance.

|
Change in alkaline phosphatase (ALP) levels
Zeitfenster: Baseline and following 2L therapy (at doctor's discretion, within 7 month timeline)
|
ALP levels (where lower levels reflect better control of PBC disease) will be measured in patients both before and after a second-line therapy (2L) is started.
|
Baseline and following 2L therapy (at doctor's discretion, within 7 month timeline)
|
|
Changes in Daily Fatigue Impact Scale.
Zeitfenster: 7 months (1 month screening and 6 months wearing the device)
|
The Daily Fatigue Impact Scale measures how fatigue interferes with daily functioning.
Scores range from 0 to 32, with higher numbers indicating a greater severity of fatigue.

The ESS score (the sum of 8 item scores, 0-3) can range from 0 to 24.
A result from 11 to 24 indicates excessive (abnormal) daytime sleepiness.
