We measured the numbers of helper (OKT4) and suppressor (OKT8) T-cells in blood and bronchoalveolar lavage (BAL) in 6 patients who developed single early reactions after allergen inhalational challenge and in 6 subjects who developed dual (early- and late-phase) responses. The asthmatics were lavaged twice. On the first occasion, they inhaled the diluent control (Dil) solution, and after an interval of at least 7 days, allergen (Ag) inhalational challenge was undertaken. Significant differences were observed in the single early responders (SER) only. For instance, when the results obtained on the Dil day were compared with those obtained on the Ag day, there was a significant (p less than 0.05) increase in the percentage of OKT4 cells in the blood of SER. Also in the BAL of SER there was a significant (p less than 0.05) decrease in the percentage of OKT4 and an increase (p less than 0.05) in the percentage and absolute numbers of OKT8 cells. Furthermore, the percentage of OKT4 was highly significantly (p less than 0.005) lower on the Ag day in the SER than on the Ag day in the late-phase responders (LPR). The OKT4/OKT8 ratio was significantly (p less than 0.05) lower on the Ag day than on the Dil day in BAL from SER and highly significantly decreased (p less than 0.001) when results on the Ag day in the SER were compared with those on the Ag day in the LPR. These findings raise the possibility that mobilization of suppressor T-cells into the lung after allergen-induced single early reactions in asthma might be associated with the prevention of a subsequent late-phase response.
