Skin sensitization with the new reagents NOPYE (4-nitro-1-cyclohexyl-3-ethoxy-2-oxo-3-pyrroline) and NOPY-L-phenylalanine.

The aim of this study was to investigate the compound 4-nitro-1-cyclohexyl-3-ethoxy-2-oxo-3-pyrroline (NOPYE) and some related compounds for skin sensitization in guinea pigs, as the first step in a search for more effective skin sensitizers for immunotherapy of cutaneous tumors. In guinea pigs, NOPYE and NOPYE-L-alanine produce far milder delayed hypersensitivity reactions than DNCB. Both NOPYE and DNCB fail to act as adjuvants for skin sensitization to tuberculin purified protein derivative (PPD) and ovalbumin (OV). This suggests an explanation for the lack of effectiveness of DNCB in immunotherapy of metastases: DNCB may be relatively ineffective as an adjuvant for production of specific antitumor immunity. Such adjuvant activity may be essential if the action of the immunotherapeutic reagent is not to be confined to its site of application but is to be effective at the site of distant metastases.

Comparison of different epithelial substrates useful for indirect immunofluorescence testing of sera from patients with active pemphigus.

A positive statistical correlation between intercellular antibody titer and disease severity was found for a group of 6 patients with active pemphigus vulgaris, irrespective of whether indirect IF testing was performed on 5 different epithelial substrates which included guinea pig esophagus, human foreskin, rabbit esophagus, monkey esophagus and monkey lip. In a group of 4 patients with pemphigus foliaceus a positive correlation between disease severity and titer was found only when rabbit esophagus was used for indirect fluorescence testing. In both groups of patients there were individual patients in whom the antibody titer was positive at a time when no disease was present and conversely, there were some patients in whom the antibody titer was negative at a time when extensive disease was present. Because of this inconsistency, the use of antibody titers to monitor disease activity and therapy in individual patients may not be justifiable.

Correlation of antibodies in skin and serum with disease severity in pemphigus.

Direct and indirect immunofluorescence (IF) testing was performed on 63 patients with active or inactive pemphigus in order to determine the reliability of these tests for diagnosis and for monitoring disease severity. Direct IF was positive in 58 of 63 patients with pemphigus. The five patients with negative direct IF had been free of lesions for more than a year. Thus, the direct IF test is a reliable diagnostic procedure that shows positive findings early in the disease. Indirect IF is inferior to direct IF as a diagnostic test because it may be negative in early cases, as observed in four patients. Furthermore, indirect IF, contrary to claims, is not reliable for evaluating the status of the disease. Thus, in patients with lesions and receiving treatment, 41% of the determinations showed a negative titer; whereas in patients free of lesions, 45% of the determinations showed a positive titer. In particular, seven patients without lesions and without treatment for more than a year had a positive titer.
