Systemic Inflammation and Oxidative Stress Markers in Patients With Medication Overuse Headache

Area of Science:

• Neurology
• Immunology
• Biochemistry

Background:

• Inflammation and oxidative stress are implicated in the pathogenesis of medication overuse headache (MOH).
• Peripheral markers of systemic inflammation and oxidative stress require further investigation in MOH.

Purpose of the Study:

• To investigate differences in peripheral inflammation and oxidative stress markers between MOH patients, episodic migraine patients, and healthy controls.
• To explore the correlation of these markers with clinical symptoms in MOH patients.

Main Methods:

• A cross-sectional study involving 109 MOH patients, 68 episodic migraine patients, and 86 healthy controls.
• Comparison of monocyte to HDL ratio (MHR), lymphocyte to HDL ratio (LHR), and neutrophil to HDL ratio (NHR) across groups.
• Logistic regression analyses to identify independent factors associated with MOH.

Main Results:

• MOH patients showed significantly higher MHR, LHR, and NHR compared to healthy controls.
• Elevated MHR, LHR, and NHR were independently associated with MOH.
• The triglyceride-glucose index was negatively correlated with monthly headache days in MOH patients.

Conclusions:

• MOH patients exhibit distinct inflammatory and oxidative stress profiles.
• Elevated LHR, MHR, and NHR are independently associated with the occurrence of MOH.
