An induction of the late hypersensitivity reaction to DNCB in patients with different clinical forms of hanseniasis in Brazil.
One hundred and twenty Brazilian patients with several forms of hanseniasis were tested with DNCB. The results were the following: 1) the sensitization of patients with hanseniasis to DNCB was lower than that seen in the general population; 2) the sensitization of the borderline and virchowian forms of hanseniasis were lower than that seen in the indeterminate and tuberculoid forms.
