High incidence of Meniere-like symptoms in relatives of Meniere patients in the areas of Oulu University Hospital and Kainuu Central Hospital in Finland

Abstract

Objective of this study was to systematically investigate the family histories of a large set of patients affected with Meniere's disease to determine the prevalence of familial MD and Meniere-like symptoms in their families. All 640 patients treated at the Oulu University Hospital and Kainuu Central Hospitals during 2005–2010 for Meniere's disease were selected as the initial study population. A postal family history survey was sent to all subjects. Hospital records of all patients were studied to confirm diagnosis and sufficient differential diagnosis. All patients that revealed a positive family history of Meniere's disease or Meniere-like symptoms were phone interviewed and the probability of Meniere's disease in a relative was estimated on a three level scale: probable, possible or unlikely. Affected family members of the patients were recruited to the study if possible. Familial Meniere's disease could be confirmed in 9.3% of patients, but 32.7% patients reported Meniere-like symptoms in their family. It was not possible to confirm all cases, but a family history of Meniere's disease was convincing (confirmed or probable) in 23.4% of the patients. Genetic factors are significant in the development of Meniere's disease.
