Mycobacterial lymphadenitis in eastern Sydney.
BACKGROUND
There has been a resurgence of tuberculosis (TB) in the developed world, especially extrapulmonary manifestations, of which lymphadenitis is the most common. We reviewed all cases of mycobacterial lymphadenitis notified in the eastern suburbs of Sydney from 1989 to 1996.


OBJECTIVE
To review all cases of mycobacterial adenitis in eastern Sydney.


METHODS
This was a retrospective review of the medical records of 54 patients (aged 1.2 to 84 years), recruited from all notifications of TB presenting as lymphadenitis at Prince of Wales, Sydney Children's and St Vincent's Hospitals.


RESULTS
There were two distinct groups: Group 1, patients with Mycobacterium tuberculosis (MTB), n = 37 (68.5%), Group 2, patients with atypical mycobacteria, n = 17 (31.5%). For Group 1, 83.3% were foreign born and 18.9% were positive for the human immunodeficiency virus (HIV). Disease involved single node groups in 73% (the cervical chain was involved in 70.1%). Complete resolution of lymphadenopathy at conclusion of treatment occurred in 73.1%. Outcome was not documented in 13.5%, of the rest; 83.8% completed treatment; 2.7% were lost to follow up before treatment concluded; 2.7% were still being seen at the time of writing and 10.8% died within six months of treatment starting (all were HIV positive). HIV positive patients had more diffuse disease. Group 2 were all Australian born. They comprised children less than six years who were all HIV negative and adults (aged 30-55 years) who were all HIV positive. The children were all treated surgically with 80% having complete resolution of their modes. Those adults with HIV had a mortality of 83.3% during treatment.


CONCLUSIONS
In eastern Sydney lymphadenitis caused by MTB in the HIV negative population is mostly seen in those who are immigrants. Our large proportion of HIV positive patients tended to have diffuse disease and a high mortality. The reporting of outcomes was poor and in a greater than expected number of outcome and follow up were inadequately documented.
