|Abstract||Glutathione transferase mu activity, a marker for susceptibility to lung cancer and chemically induced cytogenetic damage, is not a predictive index for the predisposition to sulphonamide hypersensitivity reactions. However, considering the functional diversity and broad, overlapping substrate specificity of GSH-dependent enzymes, it is conceivable that an as yet unidentified deficiency in another GST isozyme or GSH-related enzyme may be a marker for sulphonamide toxicity. In addition, heterogeneity in cellular repair mechanisms and the diversity of the human immune response  may also contribute to the manifestation of the toxic effects of sulphonamides. Experiments are currently in progress to determine which of this myriad of variables is predominantly responsible for inter-individual susceptibility to the idiosyncratic reactions produced by these antibacterial agents.|
