	==Introduction==		==Introduction==
	Nephritis is an inflammatory condition affecting one or both kidneys. It is usually classified into two major types: [[glomerulonephritis]] and [[interstitial nephritis]]. Nephritis can lead to significant kidney damage and failure if not appropriately treated, making it a critical health concern.<ref>[[Glassock, R. J.]], "Primary, Secondary, and Tertiary Prevention of Nephritis and Nephropathy", [[Nature Clinical Practice Nephrology]], 2006, 2: 526-533.</ref>		Nephritis is an inflammatory condition affecting one or both kidneys.
