Radiographic Contrast Media

Background:Many papers have focused on the importance of granulocytes in the process of reperfusion and ischemia. Most of the clinical studies measured several parameters of this process during and after coronary angiography, without taking into account the effect of the radiographic contrast media (RCM) used during this procedure.Materials and methods:We performed a randomized patient study(n=37)to evaluate the effect of ionic and non-ionic RCM on granulocyte adhesion during coronary angiography. We also evaluated the influence of the ionicity and osmolarity of the different substances on granulocyte adhesion molecules inin vitroexperiments.Results:The osmolarity of patient serum samples increased from 302±1 to 309±1 mOsm/kg(P<0.05)after infusion of RCM. The CD11b expression in the samples of the non-ionic RCM treated group increased from 221±21 MFI to 377±30 MFI(P<0.05)measured as the absolute mean fluorescence intensity (MFI), yet did not alter significantly in the ionic RCM group. In contrast, thein vitroexperiments showed a reduction of the CD11b expression from 360±70 MFI to 149±30 MFI(P<0.05)in the ionic RCM group.Conclusions:The upregulation of adhesion molecules was significantly reducedin vivowith ionic RCM, while ionic substances caused opposite effectsin vitro. This effect should be taken into account when performing leukocyte functional analysis of samples taken during angiography.

Toxic Concentrations

The use of radiographic contrast media is occasionally accompanied by more or less serious adverse effects, evidently of complex etiology, following intravascular administration. Some of these reactions are suspected of having an allergic basis. The in vitro and in vivo formation of iodinated serum proteins following gamma irradiation in the presence of two commonly used radiographic contrast media is demonstrated. Non-toxic concentrations of ascorbate present during the irradiation is shown to prevent the formation of such iodo-proteins in vitro as well as in vivo. The amounts of potentially antigenic iodoprotein formed during radiographic procedures will certainly be very small, but this quantity may be sufficient to elicit a hypersensitivity reaction in cases when an individual has been previously sensitized to immunologically similar iodo-proteins, a mechanism that could account for certain rare and unpredictable reactions. The radiation induced formation of iodo-proteins may also serve as a model for the formation of iodine containing antigens mediated by a free radical mechanism, i.e. in the metabolism of iodinated compounds like erythrosine, a widely used colouring agent for certain foods.
