A case of tubulointerstitial nephritis in a patient with an influenza H1N1 infection.
BACKGROUND
Patients suffering from an H1N1 infection mainly suffer from respiratory symptoms but may also develop symptoms in other organ systems, such as the kidneys.


METHODS
A 4 ½ year-old boy was admitted with relatively mild respiratory symptoms of H1N1 infection, but developed severe generalized proximal tubular dysfunction with sterile leucocyturia and a reversible rise in serum creatinine. He made a full recovery with supportive therapy.


CONCLUSIONS
Influenza H1N1 may be associated with acute tubulointerstitial nephritis.
