[Parainfectious glomerulonephritis]

Acute postinfectious glomerulonephritis is uncommon in adults especially in developed countries. Streptococcus is the most frequently identified infectious agent in younger patients and staphylococcus in older patients. The most common sites of infection are the upper respiratory tract and skin in younger patients and skin followed by respiratory and urinary tract in older patients. The prognosis is often poor in older patients and in those with an immunocompromised background including diabetes, malignancy, alcoholism, AIDS, or intravenous drug use. Outcome does not seem to correlate with steroid treatment.
