Plain Language Summary
FAERS pharmacovigilance analysis identifying drugs disproportionately associated with carpal tunnel syndrome reports, with GH-axis agents including tesamorelin among the identified drugs—consistent with the known adverse effect of GH-stimulated IGF-1 elevation causing fluid retention and nerve compression. Characterizes CTS as a class effect of GH-axis therapies. Provides real-world pharmacovigilance evidence for CTS as a known adverse effect of tesamorelin—confirming the clinical trial signal and informing monitoring recommendations for patients on tesamorelin, particularly those with risk factors for nerve compression who may require dose modification or discontinuation.
Abstract
OBJECTIVE: Carpal tunnel syndrome (CTS) is a prevalent compression neuropathy with multiple well-documented mechanical and systemic risk factors. However, the role of pharmacological agents in the development of CTS remains underexplored. This study aims to identify drugs disproportionately associated with CTS reports using data from the Food and Drug Administration Adverse Event Reporting System (FAERS).
METHODS: A retrospective pharmacovigilance analysis was conducted using OpenVigil 2.1 to evaluate adverse event (AE) reports of CTS from the FAERS database from October 2003 to September 2024. Only drugs identified as the primary suspect in at least 10 AE reports were included. Disproportionality analysis, including reporting odds ratios (RORs), was used to assess associations between CTS and specific drugs. Positive signals were validated using Bayesian confidence propagation neural network algorithms, with drugs having ROR ≥10 and significant Bayesian confidence intervals (IC025 > 0) considered strongly associated with CTS.
RESULTS: Of 12,929,504 AEs reported during the study period, 6,837 (0.05%) involved CTS. Female patients comprised 69.5% of CTS cases, with a mean age of 57.0±14.9 years. Ten drugs were found to have significant overreporting of CTS, including idursulfase (ROR=51.2, 95% CI=39.0-67.2), galsulfase (ROR=26.8, 95% CI=17.2-41.7), laronidase (ROR=20.9, 95% CI=14.4-30.3), tesamorelin (ROR=20.7, 95% CI=13.7-31.3), anastrozole (ROR=20.6, 95% CI=17.0-24.9), alendronic acid (ROR=17.1, 95% CI=14.5-20.1), gamma-hydroxybutyric acid (GHB) (ROR=16.3, 95% CI=9.6-27.6), rofecoxib (ROR=16.1, 95% CI=14.3-18.2), alendronate (ROR=12.9, 95% CI=11.0-15.2), and tafamidis (ROR=12.0, 95% CI=9.2-15.7).
CONCLUSIONS: Several drugs were disproportionately associated with CTS in the FAERS database, including enzyme replacement therapies (ERTs), aromatase inhibitors, bisphosphonates, growth hormone (GH)-releasing factor analogs, GHB, rofecoxib, and tafamidis. These findings highlight the critical need for increased vigilance and monitoring of new-onset or worsening CTS in high-risk populations prescribed the aforementioned medications. Clinicians should carefully scrutinize pharmacological history when evaluating patients in this context.
