Complementary bodybuilding : a potential risk for permanent kidney disease

Abstract EN

We report our experience of renal disease associated with bodybuilders who had been on high-protein diet, anabolic androgenic steroids (AASs), and growth hormone (GH) for years.

A total of 22 adult males who volunteered information about use of high protein diet and AAS or GH were seen over a six-year period with renal disease.

Kidney biopsy revealed focal segmental glomerulosclerosis (FSGS) in eight, nephroangiosclerosis in four, chronic interstitial nephritis in three, acute interstitial nephritis in two, nephrocalcinosis with chronic interstitial nephritis in two, and single patients with membranous glomerulopathy, crescentic glomerulopathy, and sclerosing glomerulonephritis.

Patients with FSGS had a longer duration of exposure, late presentation, and worse prognosis.

Those with interstitial disease had shorter exposure time and earlier presentation and had improved or stabilized after discontinuation of their practice.

There is a need for health education for athletes and bodybuilders to inform them about the risks of renal disease involved with the use of high-protein diet, AAS, and GH.
