title: Dinitrochlorobenzene sensitization in children with bronchial asthma.
abstract: Twenty-one patients with bronchial asthma were tested by dinitrochlorobenzene. Eleven did not react (52%). Five of the patients had been previously BCG vaccinated but did not react to PPD. The results indicated that some impairment of cell-mediated immunity in asthmatics exists. The correlation between this finding and pathogenesis of asthma is discussed.
