[Acute focal bacterial nephritis in a case of AIDS].

Presentation of one case of bacterial acute focal nephritis (acute lobe nephrosis) in a parenterally drug-abuser, HIV-infected male. From the clinical point of view, the picture was interpreted as acute hepatitis, and the lesion was detected by ultrasound techniques. A right side location, relative lack of urological symptoms and coexistence of a chronic liver disease contributed to the diagnostic error. Failure of initial response to therapy with antibiotics coincided with the lesion migration. Eventually, the case evolved favourable with conservative treatment.
