Clinical observation of palatine tonsils with IgA nephropathy.

We have previously reported that clinical remission could be achieved by combination therapy consisting of steroid pulse therapy and tonsillectomy in patients with IgA nephropathy. However, there is no consensus as to the indications for tonsillectomy in IgA nephropathy (IgAN) patients. To clarify whether there is any correlation between characteristics of removed palatine tonsils and clinical remission rate, we evaluated the relationships between the remission rate of urinary abnormalities and characteristics of 186 IgAN patients (aged 11-65 years) with mild or moderate renal pathology and their tonsils.
