Vibratory angio-oedema is a rare form of physical urticaria characterized by pruriginous weals and angio-oedema at the site of exposure to vibration. Severe treatment-resistant disease can occur, and is associated with significant disability. Therapy with omalizumab, a monoclonal IgG anti-IgE antibody, has been shown to be successful in several types of physical urticaria. We report a patient with vibratory angio-oedema for whom all standard treatments for urticaria, including omalizumab, failed to show a clinical benefit. Finally, ketotifen was tried, and unexpectedly reduced symptoms significantly. Ketotifen may thus represent a therapeutic option in patients with treatment-resistant vibratory angio-oedema.

Vibratory angioedema is a rare form of physical urticaria, hereditary or acquired, which occurs at body sites exposed to vibrations. Pathogenic mechanisms of disease are not completely clear and, consequently, current pharmacological treatment is sometimes unsatisfactory. We report the case of a horn player affected by acquired vibratory angioedema, relapsing after prolonged use of the instrument and resistant to systemic antihistamines and corticosteroids, which successfully responded to therapy with low doses of amitriptyline and bromazepam. A neuroinflammatory mechanism can be likely implicated in the pathogenesis of vibratory angioedema, in line with many different cutaneous/mucosal diseases involving a complex interplay of homeostatic/allostatic systems. Furthermore, in mucosal diseases, such as vibratory angioedema, physical/psychological stressors have a relevant role. In such cases, because of the complex interplay between nervous and immune system, the pharmacological activity of benzodiazepines and typical antidepressants may downregulate neuroinflammation.

Vibratory angioedema (VA) is a rare, inherited type of physical urticaria characterized by acute onset of mucosal and / or cutaneous edema that is triggered by vibration. We report a case of a 63-year-old woman with VA elicited by use of mechanized (vibratory) dental equipment. To our knowledge, this is the first report of VA induced by mechanical dental equipment.
