A case of mycoplasma pneumoniae infection associated acute interstitial Nephritis

Acute interstitial nephritis is an important cause of acute renal failure and result from immune mediated tubulointerstitial injury, initiated by medications, infections, and other variable causes. Since acute interstitial nephritis may present a variety of clinical and laboratory findings and progress more rapidly than expected and it is reversible with withdrawal of the etiologic drug or administration of steroid, its early detection is very important. Mycoplasma pneumoniae is a common pathogen in young-healthy adult but mycoplasma infection induced acute interstitial nephritis is rarely reported. Therefore considering mycoplasma infection as one possible cause of acute interstitial nephritis is clinically important. So we report a case of acute interstitial nephritis associated with mycoplasma infection. (Korean J Nephrol 2006;25(1):115-119)
