Objective: The pronociceptive neuromediator calcitonin gene-related peptide (CGRP) is associated with pain transmission and modulation. After spontaneous subarachnoid hemorrhage (sSAH), the vasodilatory CGRP is excessively released into cerebrospinal fluid (CSF) and serum and modulates psycho-behavioral function. In CSF, the hypersecretion of CGRP subacutely after good-grade sSAH was significantly correlated with an impaired health-related quality of life (hrQoL). Now, we prospectively analyzed the treatment-specific differences in the secretion of endogenous CGRP into plasma after good-grade sSAH and its impact on hrQoL.

Methods: 26 consecutive patients (f:m=13:8; mean age 50.6 years) with good-grade sSAH were enrolled (drop out n=5): n=9 underwent endovascular aneurysm occlusion, n=6 microsurgery, and n=6 patients with perimesencephalic SAH received standardized intensive medical care. No patient developed any serious vasospasm-related ischemic or hemorrhagic complications. Plasma was drawn daily from day 1-10, at 3 weeks, and at the 6-month follow-up (FU). CGRP levels were determined with competitive enzyme immunoassay in duplicate serum samples. All patients underwent neuropsychological self-report assessment [36-Item Short Form Health Survey (SF-36) and ICD-10-Symptom-Rating questionnaire (ISR)] after the onset of sSAH (t1: day 11-35) and at the FU (t2).

Results: During the first 10 days, the mean CGRP levels in serum (.470 ± .10 ng/ml) were significantly lower than the previously analyzed mean CGRP values in CSF (.662 ± .173; p=.0001). The mean serum CGRP levels within the first 10 days did not differ significantly from the values at 3 weeks (p=.145). At 6 months, the mean serum CGRP value (.429 ± .119 ng/ml) was significantly lower compared to 3 weeks (p=.0001) and compared to the first 10 days (p=.026). Higher mean serum CGRP levels at 3 weeks (p=.0001) and at 6 months (p=.0242) correlated with a significantly poorer performance in the SF-36 item pain, and, at 3 weeks, with a higher ISR symptom burden regarding somatoform syndrome (p=.0310) at t2.

Conclusion: Our study reveals the first insight into the serum levels of endogenous CGRP in good-grade sSAH patients with regard to hrQoL. In plasma, upregulated CGRP levels at 3 weeks and 6 months seem to be associated with a poorer mid-term hrQoL in terms of pain. In migraineurs, CGRP receptor antagonists have proven clinical efficacy. Our findings corroborate the potential capacity of CGRP in pain processing.
