Coexistence of Interstitial Nephritis and the Cellular Variant of Focal Segmental Glomerulosclerosis Secondary to Anabolic Steroid Abuse.

Anabolic-androgenic steroids (AAS) have been widely used by young people to enhance performance and increase muscle mass. The use of AAS can affect the kidneys and lead to a myriad of presentations, ranging from mildly elevated serum creatinine and blood urea nitrogen to irreversible chronic kidney disease and focal segmental glomerulosclerosis (FSGS). To the best of our knowledge, the coexistence of interstitial nephritis and the cellular variant of FSGS [Immunoglobulin M (IgM)] secondary to AAS abuse has not been previously reported in the literature. Here, we report the case of a 40-year-old bodybuilder who developed simultaneous interstitial nephritis and the cellular variant of FSGS (IgM) after short-term use of AAS and other dietary supplements.

Milk-Alkali syndrome induced by H1N1 influenza vaccine.

Milk-Alkali syndrome (MAS) consists of a triad of hypercalcemia, metabolic alkalosis, and acute renal failure. We hereby report a 75-year-old Indian gentleman who presented to our emergency department with a history of generalized weakness and easy fatigability. Investigations were consistent with MAS secondary to calcium carbonate and calcitriol treatment to prevent osteoporosis, aggravated by H1N1 influenza vaccine. The patient was treated with hemodialysis and zoledronate. To our knowledge, this is the first reported case of such association in the literature.
