Use of testosterone in the treatment of cluster headache.

Klimek A

The study was carried out on 15 men suffering from the episodic form (12 patients) and the chronic one (3 patients) of cluster headache. Before treatment the patients did not receive any drugs, and after determining the index of attacks the treatment was commenced. For 7-10 days patients were given testosteronum propionicum (25 mg) once a day intramuscularly, and then for the same period of time testosterone (10 mg). Before treatment the index of attacks was 3.66 (total number of attacks 308). In the 1st week of treatment the index decreased to 1.11 (total number of attacks 94) and to 0.16 in the 2nd week. In 3 patients with the chronic form of cluster headache testosterone was ineffective.

Testosterone replacement therapy for treatment refractory cluster headache.

Objectives.-To describe the clinical characteristics and laboratory findings of cluster headache patients whose headaches responded to testosterone replacement therapy. Background.-Current evidence points to hypothalamic dysfunction, with increased metabolic hyperactivity in the region of the suprachiasmatic nucleus, as being important in the genesis of cluster headaches. This is clinically borne out in the circadian and diurnal behavior of these headaches. For years it has been recognized that male cluster headache patients appear overmasculinized. Recent neuroendocrine and sleep studies now point to an association between gonadotropin and corticotropin levels and hypothalamically entrained pineal secretion of melatonin. Results.-Seven male and 2 female patients, seen between July 2004 and February 2005, and between the ages of 32 and 56, are reported with histories of treatment resistant cluster headaches accompanied by borderline low or low serum testosterone levels. The patients failed to respond to individually tailored medical regimens, including melatonin doses of 12 mg a day or higher, high flow oxygen, maximally tolerated verapamil, antiepileptic agents, and parenteral serotonin agonists. Seven of the 9 patients met 2004 International Classification for the Diagnosis of Headache criteria for chronic cluster headaches; the other 2 patients had episodic cluster headaches of several months duration. After neurological and physical examination all patients had laboratory investigations including fasting lipid panel, PSA (where indicated), LH, FSH, and testosterone levels (both free and total). All 9 patients demonstrated either abnormally low or low, normal testosterone levels. After supplementation with either pure testosterone in 5 of 7 male patients or combination testosterone/estrogen therapy in both female patients, the patients achieved cluster headache freedom for the first 24 hours. Four male chronic cluster patients, all with abnormally low testosterone levels, achieved remission. Conclusions.-Abnormal testosterone levels in patients with episodic or chronic cluster headaches refractory to maximal medical management may predict a therapeutic response to testosterone replacement therapy. In the described cases, diurnal variation of attacks, a seasonal cluster pattern, and previous, transient responsiveness to melatonin therapy pointed to the hypothalamus as the site of neurological dysfunction. Prospective studies pairing hormone levels and polysomnographic data are needed.
