A case was described of a 28 year old plumber who suffered from gross hematuria and segmental proliferative glomerulonephritis with immunoglobulin-A deposits who requested a health hazard evaluation from NIOSH. A detailed examination of needle biopsy material revealed the presence of capillary adhesions to Bowman's capsule and fibrin in the glomerular mesangial deposits, which was suggestive of a progressive autoimmune disease. He had been working with plastic pipe and plastic cement for 9.5 years and had no family history of kidney disease. Monitoring of his workplace identified a very high exposure (range, 389 to 757 parts per million (ppm)) to tetrahydrofuran (109999) (THF), which is a component of polyvinyl- chloride pipe cement. The high exposure values occurred while the plumber glued pipe sections in confined spaces. He was also potentially exposed to cyclohexanone (108941) and methylethyl-ketone (78933) which were also present in the cement. The concentration of cyclohexanone was not measurable, but that of methylethyl-ketone was in the range of 3.9 to 5.0ppm. The short term exposure limit for THF recommended by NIOSH is 250ppm. Although the authors do not conclude that the immunoglobulin-A nephropathy has been caused by THF, they suggest that a predisposition toward the disease could be exacerbated by the massive short term exposure to solvent.
