Migraine and ergot use increase plasma pentraxin 3 levels: an Egyptian study.

Background: Endothelial dysfunction and inflammation are linked to migraine, which may contribute to atherogenesis and increase the risk of ischemia. In migraineurs, preclinical vascular involvement manifested as compromised structural characteristics of vessel wall has not received enough attention or evaluation.

Objectives: To measure plasma pentraxin 3 as an indicator of endothelial dysfunction in migraine in comparison to controls and to examine its correlation with clinical characteristics, headache severity, and brain magnetic resonance imaging findings.

Background: Early diagnosis of CH is a cornerstone and it is important to detect causes leading to diagnostic delay. Limited published data exist regarding CH in Egypt, and with no data showing characteristics of CH or causes of diagnostic delay .

Aim: To investigate clinical characteristics, for CH and detect causes of diagnostic delay in Egypt.
