Changing concepts in pathogenesis and morphology of analgesic nephropathy as seen in Europe. 1978

F J Gloor

A detailed analysis of 60 autopsy cases of AN is presented. Renal papillary necrosis is the hallmark of AN. Special emphasis is given to early changes in the basement membranes and the ground substance of the renal papilla observed by light and electron microscopy. The "interstitial nephritis" in the renal cortex is secondary to papillary changes. The histologic picture of the cotex is often complicated by bacterial infection and, therefore, is complex. An unusual hyalinization of small vessels beneath the urothelium of the mucosa of the urinary tract, similar to that seen in the inner medullary zone, has been called "analgesic microangiopathy". Its significance is not clear. The renal papillae, the mucosal membranes of the urinary tract, the liver, the cartilages, and the skin often display a striking brownish discoloration caused by a lipid-containing pigment. Statistical data from out autopsies in Switzerland show no decrease in death rates of AN. This is in contrast to reports from Denmark and Sweden where the sale of phenacetin has been restricted by prescription.

UI	MeSH Term	Description	Entries
D007672	Kidney Cortex	The outer zone of the KIDNEY, beneath the capsule, consisting of KIDNEY GLOMERULUS; KIDNEY TUBULES, DISTAL; and KIDNEY TUBULES, PROXIMAL.	Cortex, Kidney
D007674	Kidney Diseases	Pathological processes of the KIDNEY or its component tissues.	Disease, Kidney,Diseases, Kidney,Kidney Disease
D007679	Kidney Medulla	The internal portion of the kidney, consisting of striated conical masses, the renal pyramids, whose bases are adjacent to the cortex and whose apices form prominent papillae projecting into the lumen of the minor calyces.	Kidney Papilla,Kidney Medullas,Kidney Papillas,Medulla, Kidney,Medullas, Kidney,Papilla, Kidney,Papillas, Kidney
D007681	Kidney Papillary Necrosis	A complication of kidney diseases characterized by cell death involving KIDNEY PAPILLA in the KIDNEY MEDULLA. Damages to this area may hinder the kidney to concentrate urine resulting in POLYURIA. Sloughed off necrotic tissue may block KIDNEY PELVIS or URETER. Necrosis of multiple renal papillae can lead to KIDNEY FAILURE.

D008138	Loop of Henle	The U-shaped portion of the renal tubule in the KIDNEY MEDULLA, consisting of a descending limb and an ascending limb. It is situated between the PROXIMAL KIDNEY TUBULE and the DISTAL KIDNEY TUBULE.	Ascending Limb of Loop of Henle,Descending Limb of Loop of Henle,Henle Loop

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009092	Mucous Membrane	An EPITHELIUM with MUCUS-secreting cells, such as GOBLET CELLS. It forms the lining of many body cavities, such as the DIGESTIVE TRACT, the RESPIRATORY TRACT, and the reproductive tract. Mucosa, rich in blood and lymph vessels, comprises an inner epithelium, a middle layer (lamina propria) of loose CONNECTIVE TISSUE, and an outer layer (muscularis mucosae) of SMOOTH MUSCLE CELLS that separates the mucosa from submucosa.

D009395	Nephritis, Interstitial	Inflammation of the interstitial tissue of the kidney. This term is generally used for primary inflammation of KIDNEY TUBULES and/or surrounding interstitium. For primary inflammation of glomerular interstitium, see GLOMERULONEPHRITIS. Infiltration of the inflammatory cells into the interstitial compartment results in EDEMA, increased spaces between the tubules, and tubular renal dysfunction.

D010615	Phenacetin	A phenylacetamide that was formerly used in ANALGESICS but nephropathy and METHEMOGLOBINEMIA led to its withdrawal from the market. (From Smith and Reynard, Textbook of Pharmacology,1991, p431)	Acetophenetidin
