Special Issue Information

Dear Colleagues,

The first clinical use of botulinum toxin A was in the late 1970s when an ophthalmologist, Dr. Alan Scott, studied its effects on strabismus. [1] Ten years later, the first commercially available botulinum toxin, Oculinum, was FDA-approved to treat strabismus and blepharospasm. Oculinum was later renamed Botox in 1992. [1] Since then, the indications for Botox have expanded to include cervical dystonia, chronic migraine, hyperhidrosis, spasticity, and certain lower-urinary-tract diseases.

The use of botulinum toxin A for lower-urinary-tract dysfunction was first described by Dykstra et al. in 1988 for the treatment of detrusor external sphincter dyssynergia (DSD) in spinal-cord-injury patients. [2] Twelve years would pass before Schurch et al. would publish their results of intradetrusor injections of botulinum toxin A in spinal cord patients for neurogenic urge incontinence. [3] Despite the promise that botulinum toxin A showed in regard to treating lower-urinary-tract disease, it was not until 2011 that the FDA would approve Botox for the treatment of neurogenic detrusor overactivity. FDA approval for the use of Botox for idiopathic overactive bladder subsequently followed in 2013.

In addition to the FDA-approved indications for the treatment of lower-urinary-tract dysfunction with Botox, the literature regarding urologic applications of botulinum toxin also includes conditions such as benign prostatic hypertrophy, pelvic floor hypertonicity, and interstitial cystitis. This Special Issue of Toxins will include manuscripts describing the clinical experiences of botulinum toxin when treating the lower urinary tract.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.

Semaglutide, a GLP-1 (glucagon-like peptide-1) receptor agonist, is widely prescribed for weight loss in non-diabetic populations. Given the link between obesity and overactive bladder (OAB), we explored whether GLP-1 use would improve adverse urinary events beyond its weight loss benefit for non-diabetic adults undergoing onabotulinumtoxin A (BTX-A) treatment for OAB. Using the TriNetX database, we conducted a retrospective cohort study of non-diabetic OAB patients treated with BTX-A alone or with concurrent GLP-1 therapy. Propensity score matching (1:1) was adjusted for age, race, ethnicity, hypertension, and BMI/obesity. After matching, 992 patients were included in each group. GLP-1 use was associated with a lower incidence of urinary retention (8.6% vs. 4.9%, risk difference 3.66%, p = 0.0044) and urinary tract infection (13.3% vs. 8.8%, risk difference 4.54%, p = 0.00224), with corresponding improved one-year retention-free and UTI-free survival on Kaplan–Meier (KM) analysis. Antispasmodic initiation rates were similar (11.8% vs. 10.3%, risk difference 1.55%, p = 0.6921), and KM analysis showed no significant difference. These findings suggest that GLP-1 receptor agonist use may improve select urinary adverse events in non-diabetic adults undergoing BTX-A treatment for OAB and support further investigation into its potential adjunctive role in OAB management with longer follow-up.
