Eye Dryness Evaluation in Primary Sjögren's Syndrome (PEPSS)

Pateint-reported Outcomes and Objective Eye Dryness Evaluation in Primary Sjögren's Syndrome.

The objective of this observational study is to develop new tools to assess primary Sjögren's syndrome (pSS) symptoms and to measure the severity of eye involvement in these patients.

Study Overview

• Status: Completed
• Conditions: Primary Sjögren Syndrome
• Intervention / Treatment: Other: Ecological symptom measurements using a webapp; Diagnostic test: Interferometry

Detailed Description

All clinical trials evaluating the efficacy of immunomodulatory drugs in pSS are negative. This could be due to a lack of sensitivity of the outcome measures used so far to define the response. In this study, investigator will evaluate the feasability, tolerability, and performance of new tools to assess disease evolution:

• investigator will develop a webapp to measure the intensity of the symptoms at home on a daily basis (ecological assessment)
• investigator will evaluate new ophthalmologic procedures, already used in other conditions but never in pSS, which assess the severity of eye involvement in the disease
• investigator will develop an automated method to score the severity of ocular surface lesions in the disease.

Patients with a diagnosis of pSS will be included in the study, will undergo detailed ophtalmologic examination, and will then use a webapp, installed on their smartphone, to score their symptoms everyday during 3 months.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
pSS cohort; Patients with pSS included in the study	Other: Ecological symptom measurements using a webapp; A webapp will be installed on the patients' smartphone, which will be used to collect everyday the symptoms of the patients (ESSPRI score); Diagnostic test: Interferometry; Evaluation of the mebomian function using the LipiView methodology

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Variability in the intensity of patient-reported symptoms	Variability over time (day-to-day assessment) of the ESSPRI score (dispersion of the values compared to the mean)	3 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Tolerability of the daily use of a webapp to measure the symptoms	Score Questionnaire SUS - System Usability Scale. The SUS ranges from 0 to 100, with values above 68 considered as above average.	Month 3
Interferometry	Measure of mebomian function using the LipiView technology	3 months
Automated eye surface coloration measurement	Development of an automated method using deep image mining on recorded videos	3 months
