Introduction: Tryptophan (TRP) pathway through its metabolites in serotonin and kynurenine (KYN) branches plays a crucial role in migraine pathogenesis. In addition to affecting the release of several neurotransmitters and direct peripheral effects, they also have regulatory influence on inflammatory processes. However, reliable migraine biomarkers have not been identified yet.
Aims: Our aim was to investigate trait-like alterations in tryptophan pathway and cytokine profile in interictal migraine patients without aura compared to healthy controls and their correlation with clinical parameters of migraine.
Methods: Blood samples (BS) were collected to measure plasma TRP, KYN, large neutral amino acids (LNAA), GCSF, MCP-1, RANTES, IL1, IL6, IL8, IL10 and TNFa concentration from 21 females with episodic migraine without aura and 22 healthy control females in two independent time-points. The ratio of TRP to LNAA and KYN to TRP were calculated. Differences of biomarkers between migraine patients and controls were calculated with non-parametric methods in SPSS27. Correlation analyses were also investigated between migraine frequency, age at migraine onset and biological data.
Result: Increased TRP/LNAA (1. BS: U=128, p=0.012; 2. BS: U=143, p=0.033) and decreased RANTES (1.BS: U=329, p=0.017; 2.BS: U=312, p=0.049) concentration were determined in migraine patients compared to controls. In addition, higher frequency of migraine attacks was correlated with lower KYN/TRP ratio (1. BS: rs=-0.451 p=0.046; 2. BS: rs=-0.525 p=0.018) in both time-points.
Conclusion: The increased TRP/LNAA ratio suggest an elevated TRP brain uptake in interictal migraineurs, that might prevent the development of acute attack. However, the correlation between decreased KYN/TRP ratio and increased migraine frequency suggest a downregulated KYN enzyme pathway in migraineurs. Furthermore, the decreased RANTES concentration may be the sign of vascular hypersensitivity in migraine patients.
