Clinical Validation of Digitally Acquired Clinical Data and Machine Learning Models for Remote Measurement of Psoriasis and Psoriatic Arthritis: A Proof-of-Concept Study.
J Rheumatol
August 2024
Article Synopsis
- Psoriatic disease is often overlooked, so researchers created the Psorcast app, which uses smartphone sensors to let patients self-measure their skin and joint symptoms.
- During the study, nearly half of the 104 participants had psoriatic arthritis, and the app showed a strong correlation with traditional physician assessments for skin involvement.
- The app’s results are promising, but more research with larger groups is needed before it can be used more widely in clinical practice, and the technology is open-source for public access.
Racial and ethnic determinants of psoriatic arthritis phenotypes and disease activity.
Rheumatology (Oxford)
February 2024
Objective: Individuals of racially and ethnically diverse backgrounds are underrepresented in psoriatic arthritis (PsA) research/clinical trials, despite evidence that their disease presentation, severity and course may be distinct. Here we aim to describe how race, ethnicity and other socioeconomic factors inform disease characteristics in PsA.
Methods: 817 consecutive patients with PsA from a large, diverse metropolitan area, were enrolled in an observational, longitudinal registry.
Paradoxical Effects of Depression on Psoriatic Arthritis Outcomes in a Combined Psoriasis-Psoriatic Arthritis Center.

Backgroud: Psoriatic arthritis (PsA) is a chronic, inflammatory arthritis that, when left untreated, can lead to erosions, deformities and decrease in quality of life. PsA is known to be associated with multiple comorbidities, including cardiovascular, metabolic and mental health syndromes, all of which can increase its overall morbidity and mortality.
Objective: To characterize a cohort of patients with PsA and understand the impact of depression on PsA outcome measures.
Introduction: Psoriatic arthritis (PsA) is a complex, immune-mediated disease associated with skin psoriasis that, if left untreated, can lead to joint destruction. Up to 30% of patients with psoriasis progress to PsA. In most cases, psoriasis precedes synovio-entheseal inflammation by an average of 5-7 years, providing a unique opportunity for early and potentially preventive intervention in a susceptible and identifiable population.

Here we aimed to determine the incidence of common autoantibody formation following mRNA COVID-19 vaccines in patients with inflammatory arthritis (IA) and in healthy controls.
Methods: Autoantibody seroconversion was measured by serum ELISA in a longitudinal cohort of IA participants and healthy controls before and after COVID-19 mRNA-based immunization.
