Nephritis in infectious mononucleosis.
Three patients are presented with acute nephritis associated with infectious mononucleosis. Renal biopsy in these patients indicates that an interstitial nephritis or a focal mesangial glomerulonephritis can be present. The condition can be distinguished from post-streptococcal glomerulonephritis, and should be considered in all patients presenting with acute nephritis, particularly if other features such as fever, skin rash ‘hepatitis’ or thrombocytopaenia are present.
