Glucagon-Like Peptide-1 Receptor Agonist Therapy Associated With Fewer Diagnoses of Carpal Tunnel Syndrome Within 2 Years of Treatment.

BACKGROUND

Glucagon-like peptide-1 receptor agonists (GLP-1) are approved for type 2 diabetes treatment. Given the link between diabetes-associated metabolic inflammation and increased carpal tunnel syndrome (CTS) risk, the aim of this study was to investigate development of CTS in diabetic patients who both were and were not taking GLP-1 therapy using a large claims database.

METHODS

A retrospective cohort study used a national claims database to identify diabetic patients. Those prescribed GLP-1 therapy were matched to controls by age, sex, comorbidity index, tobacco use, and obesity. Multivariable logistic regression evaluated the 2-year CTS incidence, controlling for various health conditions and socioeconomic factors. Secondary analysis also evaluated the rate of carpal tunnel release (CTR) after being diagnosed with CTS.

RESULTS

Glucagon-like peptide-1 therapy significantly reduced 2-year CTS diagnosis risk (odds ratio [OR] 0.49; 95% confidence interval [CI] 0.46-0.52; P < .001). Independent risk factors for increased CTS incidence included chronic obstructive pulmonary disease, osteoarthritis, coronary artery disease, depression, hypothyroidism, and rheumatoid arthritis (RA). Of patients who developed CTS, GLP-1 therapy was associated with increased odds of undergoing CTR (OR 1.23; 95% CI: 1.08-1.41; P = .002).

CONCLUSIONS

Glucagon-like peptide-1 therapy is associated with decreased CTS risk in diabetic patients-potentially due to improved metabolic health-and increased odds of undergoing CTR once diagnosed. Further research is needed to clarify GLP-1 therapy's role in reducing nervous system and musculoskeletal disease burden.
