We identified two siblings with exercise-induced anaphylaxis who share the HLA haplotype A3-B8-DR3 with their atopic father. The index case, a 16-year-old female, noted initial episodes at age 13. Intense pruritus, urticaria, facial edema, choking sensation, nausea, hypothermia, and collapse followed vigorous running but not swimming, cycling, racquetball, solar exposure, or cold exposure. Neither antihistamine, antiserotonin, anticholinergic nor epinephrine therapy was entirely effective or protective; only modification of running prevented episodes. Three similar episodes were noted at age 15 years by a brother who, now age 25, relates a 4-year history of seasonal rhinitis and exercise-related urticaria without anaphylactoid reaction. The remainder of the family (father, 47; mother, 46; brother, 22 years) does not have exercise intolerance. The father has allergic rhinitis; his nephew suffers exercise-induced urticaria without collapse. HLA typing revealed the father to be A1-B8-DR3, A3-B8-DR3; the symptomatic daughter to be A3-B8-DR3, A30-B5-DR8; and the symptomatic son to be A3-B8-DR3, A30-B5-DR8. The asymptomatic mother was A30-B5-DR8, A2-B7-DR5 and the asymptomatic son A1-B8-DR3, A30-B5-DR8. We describe exercise-induced anaphylaxis in a unique familial setting, perhaps linked to the HLA haplotype A3-B8-DR3.

Sudden sensorineural hearing loss may be present as a symptom in systemic autoimmune diseases or may occur as a primary disorder without another organ involvement (autoimmune inner ear disease). The diagnosis of autoimmune inner ear disease is still predicated on clinical features, and to date specific diagnostic tests are not available. We report a case of bilateral sudden hearing loss, tinnitus, intense rotatory vertigo, and nausea in a female patient in which the clinical manifestations, in addition to raised levels of circulating immune complexes, antithyroglobulin antibodies, and the presence of the HLA A1-B8-DR3 haplotype, allowed us to hypothesize an autoimmune inner ear disease. Cyclosporine-A immunosuppressive treatment in addition to steroids helped in hearing recovery that occurred progressively with normalization of the hearing function after a five-month treatment. Cyclosporine-A could be proposed as a therapeutic option in case of autoimmune inner ear disease allowing the suspension of corticosteroids that, at high dose, expose patients to potentially serious adverse events.
