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.

High Concentrations

Different amounts of diatrizoate, ioxaglate, iohexol, iodixanol, NaCl 1000 mOsm/kg, mannitol 1098 mOsm/kg, and meglumine (meglumine concentrations corresponding to the content in the diatrizoate solutions) were added to either whole blood or a suspension of granulocytes in autologous plasma, and the adherence to nylon fibers was determined. At high concentrations all the investigated contrast media (CM) inhibited granulocyte adherence. The degree of inhibition was significantly greater when the ionic CM diatrizoate and ioxaglate were used, as compared with the nonionic media. Meglumine solutions at high concentrations also inhibited adherence but significantly less than diatrizoate solutions containing the same amount of meglumine. Diatrizoate showed the greatest inhibitory effect on granulocyte adherence, and significant inhibition could be detected even with a 1.25% solution.
