Abstract:
Tumor Necrosis Factor-alpha/cachectin (TNF-alpha/cachectin), Lipopolysaccharide (LPS), ACTH, beta-Endorphin (beta-EPH), and Cortisol (F) levels were determined in 33 Headache patients: 22 patients were affected with Migraine (M) and 11 patients with Chronic Type Tension Headache (CTTH). TNF-alpha/cachectin serum level was detected in 15 out of 22 migraneous patients and in no CTTH patients. Plasma LPS was observed in 11 out of 15 TNF-alpha/cachectin positive migraneous patients (73%) and in 3 out of 11 CTTH patients (27%). A negative correlation was observed between TNF-alpha/cachectin values and either ACTH or beta-EPH. In the group of migraneous patients the presence of serum TNF-alpha/cachectin showed a sensibility of .6 and a specificity of 1. The endocrine and immunological implications concerning these data are discussed.
