Subclinical signs of kidney dysfunction following short exposure to silica in the absence of silicosis


Hotz, Philipp; Gonzalez-Lorenzo, J; Siles, E; Trujillano, G; Lauwerys, R; Bernard, A (1995). Subclinical signs of kidney dysfunction following short exposure to silica in the absence of silicosis. Nephron, 70(4):438-442.

Abstract

Signs of kidney dysfunction detectable in urinary protein excretion were searched for in a group of 86 silica-exposed workers who were compared to 86 control subjects matched for age, smoking status and body mass index. No worker had any clinical, spirometric or radiographic sign of silicosis, and exposure duration averaged 15.2 months (range: 11-20). An increase in the urinary excretion of albumin, transferrin, retinol-binding protein and N-acetyl-beta-D-glucosaminidase was found in the exposed group, and the prevalences of pathological values were also elevated in this group. By contrast, both groups had similar serum levels of creatinine and beta 2-microglobulin. These results strongly suggest that occupational exposure to silica may lead to subclinical renal effects after less than 2 years and in the absence of silicosis.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
