A study of changes in hematologic parameters in patients with migraine

Area of Science:

• Neuroscience
• Immunology
• Hematology

Background:

• Migraine is a complex neurological disorder with potential links to systemic inflammation.
• Peripheral inflammatory markers (PIMs) and hematological parameters are increasingly recognized as relevant to migraine pathophysiology.

Purpose of the Study:

• To investigate hematological parameters and PIMs in episodic migraine (EM) and chronic migraine (CM).
• To explore the diagnostic predictive value of these markers for migraine and its subtypes.
• To elucidate the role of systemic inflammation in migraine pathogenesis.

Main Methods:

• A case-control study involving 58 migraineurs (28 CM, 30 EM) and 30 healthy controls (HC).
• Comparison of hematological parameters and PIMs, including neutrophil/lymphocyte ratio, lymphocyte/monocyte ratio (LMR), and platelet/monocyte ratio (PMR).
• Receiver operating characteristic (ROC) curve analysis to assess diagnostic value.

Main Results:

• Migraineurs exhibited significantly lower monocyte counts and higher LMR and PMR compared to HC.
• Significant differences in monocyte counts, LMR, and PMR were observed among CM, EM, and HC groups.
• ROC analysis showed diagnostic potential for differentiating migraine subtypes using combinations of monocyte count, LMR, and PMR.

Conclusions:

• Migraine and its subtypes are associated with distinct alterations in monocyte counts and PIMs.
• These hematological markers possess diagnostic predictive value for migraine and its subtypes.
• The findings support the hypothesis that systemic inflammation plays a role in migraine development.
