Alteration of lung diffusion capacity in IgA nephropathy.

Objective: To establish whether changes of lung transfer for carbon monoxide (TLCO) are related to the phase of IgA nephropathy.

Methods: Respiratory function was tested in 12 children with IgA nephropathy assessed by percutaneous renal biopsy. This was done during acute exacerbations or haematuria-free phases of the disease.
