[Retrospective study of tuberculosis in the Province of Siena].
We report here the results of a retrospective study carried out on 200 tuberculosis cases admitted to the Hospital of Siena during the period 1994-2003. For each case, epidemiological, clinical and microbiological data were collected in order to analyze the trend of tuberculosis over the years and to compare our experience with similar studies. Indigenous patients were significantly older than immigrants (60.1 vs 34.2 yrs) more frequently affected by underlying chronic diseases. Overcrowding and HIV infection were predisposing conditions in 30 subjects (15% of cases) recently arrived from high endemicity countries. Pulmonary tuberculosis (TB) was diagnosed in 71% of cases, irrespective of origin. The death rate was 5%. Microbiological investigation was positive in 74.4% of examined subjects; 9.8% of isolates were resistant to one or more antituberculous drugs. The number of cases admitted to the Hospital seems to have slowly decreased in the last few years; factors that may influence this trend are discussed. Our results confirm a distinct epidemiological pattern of the disease between indigenous patients and immigrants, which is typical of low-endemicity countries. The delay in the diagnosis and management of the disease observed in this case-series report underlines the need to improve information on TB and skill in treatment, and to maintain specialized centres.
