The document presents 12 cases of renal diseases caused by various viruses. It discusses the clinical presentation and pathology of each case and identifies the virus responsible. The viruses discussed are mostly DNA and RNA viruses, including HIV, HTLV-1, parvovirus B19, hepatitis C, cytomegalovirus, BK polyomavirus, Epstein-Barr virus, human herpesvirus 8, measles, mumps, adenovirus, coxsackie B virus, and influenza A. The document also notes trends in interstitial diseases being caused by certain viruses and outlines future research using viral microarrays to identify new viral causes of renal disease.
