Objective: In this study, the risk of IgA nephropathy in Swiss albino mice following the subcutaneous administration of conjugated Haemophilus influenzae type b vaccine (PRP-T), containing capsular polysaccharide of the organism (PRP) conjugated to tetanus protein (T), was evaluated. Methods: Three treatment and corresponding control groups, each containing mice, were constituted and given 2, 4, 6 injections of 1/4 HD of PRP-T or placebo, respectively, at 2-week intervals. All mice in each treatment group were sacrificed two weeks from the last injection to examine sequential glomerular changes. Results: The niceoscpic examination of renal tissues revealed mesangial proliferation (6/7; 85%) in the first group given 2 doses of vaccine; mesangial proliferation (5/7; 72%) and increase in matrix (7/7; 100%) in the second group given 4 doses; and mesangial proliferation (7/7; 100%), increase in matrix (7/7; 100%), IgA (7/7; 100%) and C3 (3/7; 42%) deposition within mesangium in the third group given 6 doses. No histopathological changes were detected in the renal tissues of any control mouse. When the experimental groups were compared statistically with their respective controls at the light microscopic level, mesangial proliferation in the first group (p: 0.0047), mesangial proliferation (p: 0.021) and increase in matrix (p: 0.001) in the second group, mesengial proliferation (p: 0.001) and increase in matrix (p: 0.001) in the third group were determined to be significantly different. When study and control groups were compared by immunofluorescence microscopy, only the third group revealed a statistically significant difference with respect to IgA deposition (p: 0.001). C3 deposition was also demonstrated in this group, but it was not significantly different (p: 0.192). However, in no instance was a control mouse found to have any form of immune deposition. Conclusion: We concluded that conjugated Haemophilus influenzae type b vaccine, given at two-week intervals to a total of six doses, caused secondary IgA nephropathy in mice.
