Abstract
UNLABELLED: An increasing incidence of non-tuberculous mycobacterial (NTM) lymphadenitis has been reported in previously healthy children in the western world since about 1985. In this study we investigated the sociodemographic and individual characteristics of these patients. Information about patients was collected prospectively from 1977 to 1996. For comparison, an ad hoc group of hospitalized children with bacterial cervical lymphadenitis was chosen. In addition to individual characteristics, information was collected on the country of birth of the patients and their parents, and the socioeconomic characteristics of the domicile area. We identified 81 children with NTM, 14 with tuberculous and 192 with septic lymphadenitis. Significantly more parents of children with NTM than in either of the other two groups were Swedish-born and lived in privileged socioeconomic areas. CONCLUSION: The increase in NTM lymphadenitis in healthy children has taken place at the same time as the reported increase in atopic disease and asthma in childhood. Both groups of patients seem to come from favourable living conditions. It is speculated that NTM lymphadenitis, like asthma and certain other diseases triggered by the immune system, might be a "lifestyle disease".
