Diabetic Neuropathy Pain Management: A Global Challenge

Area of Science:

• Neurology
• Diabetology
• Pharmacology

Background:

• Painful diabetic neuropathy (PDN) is a prevalent complication of diabetes mellitus, significantly impacting patient quality of life and increasing healthcare costs.
• Existing treatments for PDN are only partially effective and associated with considerable side effects, highlighting a need for improved therapeutic strategies.
• The complex pathogenesis of PDN remains incompletely understood due to challenges in nerve sample acquisition and the lack of non-invasive diagnostic methods.

Purpose of the Study:

• To review the current understanding of PDN pathogenesis.
• To describe the clinical manifestations of PDN.
• To explore available and potential treatment options for PDN.

Main Methods:

• A comprehensive literature search was conducted using PubMed and Google Scholar with relevant keywords.
• Data from selected studies were systematically analyzed and compiled for synthesis.

Main Results:

• The review provides a simplified overview of PDN for new researchers, clarifying common misconceptions.
• Changes in skin structure and function associated with diabetes, diabetic neuropathy, and PDN are discussed.
• The limitations of current PDN pain relievers underscore the necessity of identifying and targeting altered microenvironmental factors for novel theranostic approaches.

Conclusions:

• Future therapeutic strategies for PDN should consider alterations in skin structure, function, and microenvironment in diabetic patients.
• Development of smart, targeted, and stimuli-responsive treatments is proposed to maximize pain relief.
• Minimizing side effects through precisely tailored treatments is a key objective for managing PDN.
