Abstract
BACKGROUND: Suboccipital steroid injections can be used for preventive treatment of cluster
headache but few data are available for the efficacy of this approach in clinical trials. We
aimed to assess efficacy and safety of repeated suboccipital injections with cortivazol
compared with placebo as add-on therapy in patients having frequent daily attacks.
METHODS: In our randomised, double-blind, placebo-controlled trial at the Emergency Headache
Centre in Paris, France, we enrolled adults aged 18-65 years with more than two cluster
headache attacks per day. We randomly allocated patients to receive three suboccipital
injections (48-72 h apart) of cortivazol 3·75 mg or placebo, as add-on treatment to oral
verapamil in patients with episodic cluster headache and as add-on prophylaxis for those with
chronic cluster headache, on the basis of a computer-generated list (blocks of four for each
stratum). Injections were done by physicians who were aware of treatment allocation, but
patients and the evaluating physician were masked to allocation.
The primary outcome was
reduction of the number of daily attacks to a mean of two or fewer in the 72 h period 2-4 days
after the third injection. We assessed all patients who received at least one dose of study
drug in the intention-to-treat analysis.
This study is registered with ClinicalTrials.gov, number NCT00804895.
FINDINGS: Between November, 2008, and July, 2009, we randomly allocated
43 patients (15 with chronic and 28 with episodic cluster headache) to
receive cortivazol or placebo. 20 of 21 patients who received
cortivazol had a mean of two or fewer daily attacks after injections
compared with 12 of 22 controls (odds ratio 14·5, 95% CI
1·8-116·9; p=0·012). Patients who received
cortivazol also had fewer attacks (mean 10·6, 95% CI
1·4-19·9) in the first 15 days of study than did controls
(30·3, 21·4-39·3; mean difference 19·7,
6·8-32·6; p=0·004). We noted no serious adverse
events, and 32 (74%) of 43 patients had other adverse events (18 of 21
patients who received cortivazol and 14 of 22 controls;
p=0·162); the most common adverse events were injection-site
neck pain and non-cluster headache.
INTERPRETATION: Suboccipital cortivazol injections can relieve cluster
headaches rapidly in patients having frequent daily attacks,
irrespective of type (chronic or episodic). Safety and tolerability
need to be confirmed in larger studies.
FUNDING: None.

Abstract
BACKGROUND: Greater occipital nerve stimulation (ONS) has been recently proposed to treat
severe chronic cluster headache patients (CCH) refractory to medical treatment. We report the
results of a French multidisciplinary cohort study.
METHODS: Thirteen CCH patients were operated and data were collected prospectively. All of them
suffered from CCH according to the International Headache Society classification, lasting for
more than 2 years, refractory to pharmacological prophylactic treatment with adequate trials,
with at least one daily attack. Chronic ONS was delivered through a subcutaneous occipital
electrode connected to an implanted generator, in order to induce paraesthesias perceived
locally in the lower occipital region.
RESULTS: After surgery (mean follow-up 14,6 months), the mean attack frequency and intensity
decreased by 68% and 49%, respectively. At last follow-up, 10/13 patients were considered as
responders (improvement >50%). Prophylactic treatment could be stopped or reduced in 8/13
cases. Local infection occurred in one patient, leading to hardware removal.
CONCLUSIONS: Our data confirmed the results of the 36 similar cases reported in the literature,
suggesting that ONS may act as a prophylactic treatment in chronic CH. Considering their
respective risks, ONS should be proposed before deep brain stimulation in severe refractory CCH
patients.
