Purpose : According to the 2008 WHO report, incidence, prevalence, and mortality of tuberculosis are decreasing globally. The 7th National Tuberculosis Survey of 1995 in Korea showed that the prevalence of tuberculosis was also decreasing. This study was performed to review the hospitalized childhood tuberculosis in a children’s hospital over a 20 year period.
Methods : Medical records of children <16 years of age hospitalized with the diagnosis of tuberculosis at the Seoul National University Children’s Hospital between 1988 and 2007 were reviewed retrospectively. Changes in number of patients and involved sites were also analyzed by four 5-year periods.
Results : Out of the 186 hospitalized patients, 59.1% were male. Median age at diagnosis was 5.5 years old (range, 10 days-15 years). The main involved sites included the lung (n= 54, 29%) or pleura (n=12, 6.5%), central nervous system (n=49, 26.3%), lymph node (n=15, 8.1 %), bone and joint (n=9, 4.8%), gastrointestinal tract (n=5, 2.7%) or peritoneum (n=5, 2.7%), pericardium (n=2, 1.1%) and others (n=3, 1.6%). Total 32 patients (17.2%) showed miliary pattern. The proportion of hospitalization with newly diagnosed tuberculosis among all cause hospitalization decreased from 0.61% to 0.09%, comparing the period of 1988-1992 and 2003-2007 (P<0.001) and the incidence of hospitalized tuberculosis of any involved organs also decreased with a statistical significance.
Conclusion : The data from a single children’s hospital suggest that the number of hospitalized childhood patients with tuberculosis has decreased over a 20 year period in Korea.
