Impact of Glucagon-like Peptide-1 (GLP-1) Analogs on Disease Outcomes in Psoriatic Arthritis: A Pragmatic Randomized Controlled Trial

Psoriatic arthritis (PsA) is a chronic inflammatory condition that affects the joints but can also have an effect on multiple parts of the body. This study will assess if the effectiveness of Glucagon-like peptide-1 (GLP-1) medications used to treat type 2-diabetes and weight management, or nutrition counseling can better treat individuals with Psoriatic Arthritis who are also needing treatment for obesity and type 2 diabetes. The main objectives it aims to answer are: To assess disease outcomes of PsA patients undergoing treatment for concomitant obesity and type 2 diabetes with GLP-1 analogs vs nutrition counseling. To assess effectiveness as measured by clinical and patient reported outcome measures in patients treated with GLP-1 and nutrition counseling. Participants will be randomized to receive a GLP-1 or nutrition counseling. Participants will be asked to come to the study center at most four times during a 24-week period. During this time participants will be asked to fill out questionnaires, receive a physical exam, and have their blood drawn.
