Frequent vaccination and immune complex deposition in unilateral nephrectomized mice.
The aim of this study was to investigate the effect of increased number and frequency of vaccination on immune complex deposition in the choroid plexus and glomeruli of non-nephrectomized and unilateral nephrectomized mice. Fifty-five non-nephrectomized, 40 nephrectomized, and 7 control Swiss albino mice were used. Half of each group was vaccinated only with diphtheria-tetanus and the other half with multiple vaccines, which are used in pediatric practice. Each group was divided into subgroups, which were vaccinated with increasing frequency. No immune deposits were detected in the choroid plexus of any vaccinated mice. There were immune deposits in glomeruli in 2 of 55 (3.6%) of the non-nephrectomized and in 3 of 40 (7.5%) of the nephrectomized mice (P=0.199). The difference between the diphtheria-tetanus and multiple vaccine groups in non-nephrectomized (P=0.236) and nephrectomized (P=1.000) mice was not significant. A significant positive correlation between increased frequency of vaccination and glomerular immune complex deposition 8 weeks after the last immunization was detected in the multiple vaccine group of nephrectomized mice (P=0.048, r=0.447). Our results suggest that the large number and frequent doses of vaccines would not lead to immune complex deposition in choroid plexus and do not significantly increase the deposition of immune complexes in glomeruli in unilateral nephrectomized mice compared with non-nephrectomized mice.
