There are limited studies evaluating the fibrinogen levels in patients with migraine. It remains unknown whether the levels of the haematological marker of thromboembolism, D-dimer, and the levels of galectin-3, which plays an important role in inflammation as a proinflammatory mediator, change during the attacks in patients with migraine. The present study aims to compare galectin-3, fibrinogen and D-dimer levels in patients with migraine during the attacks and interictal periods, and to compare galectin-3, fibrinogen and D-dimer levels between patients with migraine and healthy controls to investigate the role of these parameters in the pathogenesis of migraine.

The total oxidative status (TOS)/total anti-oxidative status (TAS) ratio can provide information on an individual's absolute oxidative stress index (OSI). We investigated the alterations in the oxidant-antioxidant balance by measuring the oxidant parameters OSI, TOS, and malondialdehyde (MDA) together with the antioxidant parameters such as TAS, and superoxide dismutase (SOD) in patients with relapsing remitting multiple sclerosis (MS). To our knowledge, this is the first study to evaluate OSI in patients with relapsing remitting MS.
