title: IgA myeloma associated with decreased anion gap and renal failure.
abstract: The anion gap in myeloma patients had been well studied. IgG myeloma usually has decreased anion gap, whereas IgA myeloma always presents with normal anion gap. We report an unusual presentation of IgA myeloma with decreased anion gap and renal failure due to superimposing of acetazolamide-related bicarbonate loss.
