IgA nephropathy (in its mildest form, also known as Berger disease) is highly variable, both clinically and pathologically.
The association of some cases of IgA nephropathy with syndromes that affect the respiratory tract or gastrointestinal tract, such as celiac disease, led to the suggestion that IgA nephropathy is a disease of the mucosal immune system.
Serum IgA levels are elevated in approximately half of patients with IgA nephropathy, but that increase is unlikely to play a role in the pathogenesis of the disease because markedly elevated IgA levels are observed in patients with AIDS who do not have IgA nephropathy.

 IGA NEPHROPATHY
The IgA protein damages the glomeruli, leading to blood and protein in the urine, to swelling in the hands and feet, and sometimes to kidney failure.
IgA nephropathy is a form of glomerular disease that results when immunoglobulin A (IgA) forms deposits in the glomeruli, where it creates inflammation.

 IgA nephropathy (Berger's disease) - MayoClinic.com
IgA nephropathy — also called Berger's disease — is a kidney disorder caused by abnormal deposits of the immunoglobulin A (IgA) inside the small blood vessels (glomeruli) of your kidneys.
IgA deposits in the glomeruli hamper this process and can lead to blood and protein in your urine, high blood pressure, and swelling in your hands and feet.
IgA nephropathy is the most common form of primary glomerulonephritis, a type of kidney disease that hinders your kidneys' ability to remove waste and excess fluids.

 What IgAN is (a summary)
IgA nephropathy (or Berger's Disease, IgA nephritis) is an immune complex disorder (or immune-system mediated disease) which causes IgA immune complexes to be deposited and trapped in the glomeruli (the filters in the kidneys), where they cause inflammation (called glomerulonephritis), proliferation of cells in the mesangial matrix, and eventual scarring of the glomeruli (called glomerulosclerosis).
IgA nephropathy is probably most accurately described as a circulating immune complex glomerulonephritis in which there is glomerular trapping of predominantly IgA immune complexes.
This author suspects that adult who has IgA nephropathy would eventually reach end-stage renal failure if the person lived long enough (that is, didn't die of old age or other causes first).

Although the pathophysiology of IgA nephropathy is incompletely understood, it is likely that n-3 PUFA prevents renal disease progression by interfering with a number of effector pathways triggered by mesangial immune-complex deposition.
Using an experimental mouse model in which early immunopathological hallmarks of IgA Nephropathy are induced by the mycotoxin vomitoxin (VT), the ameliorative effects of FO ingestion on this disease were evaluated in two studies.

It seems that IgA anti-gliadin antibodies are elevated in patients with IgA nephropathy, but their antiendomysial & antireticulin antibodies counter the suggestion that this disease is associated with celiac disease.
The other side of the argument is that because IgA nephropathy has been clearly demonstrated to have no visible relationship with celiac disease, and one study they cite was a trial of gluten-free diet on IgA nephropathy, which had little effect on the course of the nephropathy.
For now, it is clear that she was referring to the gluten-free diet, and this is a whole spectrum of possible gluten-intolerance that needs some investigation.
