[Acute interstitial nephritis in childhood].
Acute tubulointerstitial nephritis (TIN) was diagnosed during a 10-year period in 6 previously healthy children (4 boys) with a mean age of 10 years (range 2.5-14 years). All presented with a non-specific history. First laboratory findings were nearly identical, with a raised erythrocyte sedimentation rate and non-oliguric renal failure; the urine contained protein, glucose, and leucocytes, but no bacteria. A serologically proven infection (streptococcal infection 2x; mononucleosis 1x) or drug-related TIN (penicillin) was present in 4 children; in one, both conditions could have been responsible. One girl suffered from idiopathic TIN with uveitis. Rapid progression of renal failure occurred in 3 children, but the response to steroid therapy was satisfactory. No dialysis was necessary and all patients showed a complete recovery. We think that acute TIN occurs more frequently than suggested previously. Many episodes are probably mild or subclinical and the rate of spontaneous remission is high. The results of initial laboratory evaluation in conjunction with acute renal failure and predominantly proximal tubular dysfunction, are sufficiently typical to arouse suspicion of acute TIN at an early stage, although they do not permit any conclusion as to the aetiology.
