Factors Associated With Intermittent and Constant Pain Patterns in People With Gout: A Cross-Sectional Analysis

Area of Science:

• Rheumatology
• Pain Medicine
• Psychosomatic Medicine

Background:

• Gout is often viewed as episodic with symptom-free periods.
• However, some individuals with gout report continuous joint pain beyond acute flares.

Purpose of the Study:

• To investigate factors associated with constant versus intermittent pain patterns in individuals with gout.
• To identify predictors of persistent pain in gout patients.

Main Methods:

• Cross-sectional analysis of 90 participants with physician-diagnosed gout.
• Pain patterns (constant vs. intermittent) classified using validated graphical representations.
• Multivariable logistic regression and ROC AUC analysis to identify associated factors.

Main Results:

• 34.4% of participants reported constant pain.
• Constant pain was associated with younger age of gout onset, greater activity limitation, and co-existing anxiety or depression.
• The model effectively discriminated between constant and intermittent pain patterns (ROC AUC = 0.82).

Conclusions:

• A significant portion of gout patients experience constant pain, challenging the traditional episodic model.
• Early onset, functional impairment, and mood disturbances are linked to persistent pain in gout.
• Findings highlight the need for tailored management strategies for individuals with gout experiencing continuous pain.
