MILIARY TUBERCULOSIS IN CHILDREN - A REVIEW OF 94 CASES

This is a retrospective review of the clinical, radiologic and laboratory features of 94 cases of childhood miliary tuberculosis seen during a 5-year period, 1985 to 1989. A history of Bacillus Calmette-Guerin vaccination was documented in 88% of children. The median age at presentation was 10.5 months, 52% of cases occurring in those younger than 1 year. The presenting symptoms were nonspecific: cough (72%); fever (61%); loss of appetite and weight (40%); and diarrhea and vomiting (33%). The main presenting signs were hepatomegaly (82%), splenomegaly (54%), lymphadenopathy (46%) and pyrexia (39%). Most of the patients were malnourished and anergic. Meningitis occurred in 19% of patients and this was the only significant risk factor identified for mortality, the overall case fatality rate being 14%. The diagnosis in the vast majority was made on the clinical presentation supported by a classic miliary pattern on chest roentgenogram (91% of cases). Mycobacterium tuberculosis was cultured in 33% of cases. In addition a review of hospital admissions from 1981 to 1989 revealed that annually miliary tuberculosis in children and adults accounted for 8.3 and 1.3%, respectively, of all tuberculosis admissions. This study confirms that miliary tuberculosis is a relatively common complication of tuberculosis in young children.
