title: [Hypotension in acyclovir therapy].
abstract: A 51 year old man developed Herpes zoster on the right arm (C5/C6) treated subsequently with aciclovir infusions (500 mg, 3/day). Ten months before hospital admission he did have a radical resection of a epi-oro-hypopharyngeal carcinoma (T4/N1/G2, M0; lymphangiosis carcinomatosa) as well as a partial laryngeal resection for a recurrence 3 months later and removal of a cervical lymph node metastasis after two further months. During aciclovir treatment the patient experienced repeated bradycardia with hypotension verifiable with the tilt-table test. The bradycardias could not be further characterized by ECC. Neither sonography nor CT-scans gave an indication for infiltration of the cervical course of the vagus or glossopharyngeal nerves. Serum catecholamines were, however, markedly reduced. After cessation of aciclovir the bradycardias and hypotensive episodes disappeared. A final tilt-table test was unremarkable. A reversible autonomic neuropathy induced by aciclovir seems a possible explanation.
