A child with acute glomerulonephritis (AGN) is being discharged from the hospital. In giving follow up information to his parents, the nurse talks about which of the following infections known to lead to AGN?
Explanation
• Impetigo, a bacterial infection of the skin caused by streptococcal pyogenes, may precede AGN. Strep throat can also precede AGN.
• AGN is commonly caused by infection, but can also be caused by vasculitis, SLE, membranoproliferative glomerulonephritis, and hypersensitivity disorders.
• Although most streptococcal infections do not cause AGN, when they do, a latent period of 10 to 14 days occurs between the infection and the onset of clinical manifestations.
Incorrect options:
• Herpes simplex virus is not associated with AGN.
• Meningitis and pneumonia are commonly caused by a type of streptococcus but are not associated with AGN.
