title: Does 2-mercaptoethane sulphonate (mesna) prevent cyclophosphamide and azathioprine induced immunosuppression? In vitro studies.
abstract: The effect of 2-mercaptoethane sulphonate (mesna) on the inhibition of the human MLR by 4-hydroxycyclophosphamide or azathioprine was studied. 4-Hydroxycyclophosphamide (34 microM) completely inhibited the MLR and this inhibition was unaffected by 122 microM of 2-mercaptoethane sulphonate or its disulphide. At high concentrations (mM) 2-mercaptoethane sulphonate inhibited the MLR reaching 85% at 24 mM. 2-Mercaptoethane sulphonate (15-122 microM) had no effect on azathioprine (36 microM) inhibition. The results of these in vitro studies suggest that 2-mercaptoethane sulphonate does not interfere with cyclophosphamide or azathioprine induced suppression of cellular immunity.
