In order to study an experimental model of IgA nephropathy, C3H/HeJ mice which are high IgA responders were strongly immunized orally with ferritin and compared to syngeneic C3H/eB. C3H/HeJ exhibited a significant increase of total IgA level in the serum and of IgA deposits in the mesangium. However the low level of IgA antibody to ferritin detected in the serum and the unsuccessful search for ferritin and antibody to ferritin in the glomeruli suggest that strong oral immunization of C3H/HeJ mice leads to high level of non specific IgA in the serum and deposition of IgA in the kidney.

In order to develop an experimental IgA nephropathy, C3H/HeJ mice, high producers of IgA, were strongly immunised orally by ferritin and compared to C3H/eB mice. After immunisation, serum IgA and IgG titres increased significantly only in C3H/HeJ mice. Specific antiferritin antibody could be detected in the serum. Mesangial IgA deposits were present in most of C3H/HeJ mice after immunisation and were significantly higher than in C3H/eB mice. No ferritin deposits could be detected in the kidney. No clinical manifestation appeared in these animals.

IgA nephropathy associated with liver cirrhosis is a common disease, unlike hemochromatosis-associated renal involvement, which is uncommon. A 55-year-old man was admitted to our hospital for the acute deterioration of renal function. Laboratory tests showed extremely high transferrin saturation and serum ferritin level. Furthermore, magnetic resonance imaging revealed low-intensity signals in both T1- and T2-weighted images within the liver, diagnosed as primary hemochromatosis. Renal biopsy showed mesangial IgA deposition with cellular crescent and hemosiderin in both glomerular and tubular epithelial cells. Renal function worsened progressively after admission, and thus steroid pulse therapy was started. Renal dysfunction improved, but the patient died of cerebral hemorrhage. The present case was considered IgA nephropathy and renal hemosiderosis secondary to primary hemochromatosis. To our knowledge, this is the first report that describes the above complications in association with primary hemochromatosis.
