Diverse profiles of specific IgE response to toluene diisocyanate (TDI)-human serum albumin conjugate in TDI-induced asthma patients.
The prevalence studies on specific IgE to toluene diisocyanate (TDI)-human serum albumin (HSA) conjugate in TDI-induced asthma have shown variable results. In this study, we attempted to compare specific IgE bindings to TDI-HSA conjugate and its specificity using 3 different conjugates. Sera were collected from 20 TDI-induced asthma and 10 controls. Specific IgE were measured by ELISA using thr...
متن کاملLongitudinal study of specific antibodies to toluene diisocyanate (TDI)-human serum albumin (HSA) conjugate in patients with TDI-induced asthma
BACKGROUND An appreciable number of patients with toluene diisocyanate (TDI)-induced asthma have high serum levels of specific IgE (sIgE) antibody to TDI-human serum albumin conjugate (HSA). A recent investigation suggested a role of specific IgG (sIgG) in the development of TDI asthma. METHODS We observed the changes in the levels of specific IgE and IgG antibodies to TDIHSA conjugate in TDI...
متن کاملHeterogeneity of IgE response to TDI-HSA conjugates by ELISA in toluene diisocyanate (TDI) -induced occupational asthma (OA) patients.
Toluene diisocyanate (TDI), a low molecular weight reactive chemical, is known to be a main cause of occupational asthma (OA) in Korea. Although it is thought that inhaled TDI may act as a hapten, the precise mechanisms of TDI-induced OA are unknown. In this study, TDI-human serum albumin (HSA) conjugates (5, 10, 20 and 30 min) were prepared in the range of 1.5 to 5.0 TDI mole/HSA mole. Specifi...
متن کاملCytokine secretion patterns of T cells responding to haptenized-human serum albumin in toluene diisocyanate (TDI)-induced asthma patients.
Our understanding immune response mechanisms to chemical allergens has been limited. It was partly due to the nature of antigens, recognized by T cells, not being well characterized. In the present study, we examined a hypothesis that a reactive chemical allergen, toluene diisocyanate (TDI), react with autologous proteins, thereby inducing T cell responses to the modified self protein in vivo. ...
متن کاملTwo cases of paraoccupational asthma due to toluene diisocyanate (TDI).
Two cases of paraoccupational asthma caused by toluene diisocyanate (TDI) are reported. The first patient was a metal worker in a machine shop situated near a factory producing polyurethane foam. Symptoms at work were not explainable by any specific exposure to irritants or allergens in the work site. As the patient recalled previous occasional work in the adjacent polyurethane factory with acc...
