  • Title: NSAIDs associated nephropathy.
    Author: Pospishil YO, Antonovych TM.
    Journal: Pol J Pathol; 1998; 49(1):35-9. PubMed ID: 9640973.
    Abstract:
    Renal biopsy of 32 patients who developed renal complications after treatment with nonsteroidal anti-inflammatory drugs (NSAIDs) were studied. The treatment with NSAIDs in these cases was used for many reasons such as: headaches, toothaches, dysmenorrea, osteochondrosis, polyarthritis and acute respiratory infections. The renal function of these patients, before the treatment with NSAIDs was normal. The renal biopsies were studied by light, electron and immunofluorescence microscopy. In 32 cases treated with NSAIDs renal changes were shown. There types of morphological changes were found: focal glomerulonephritis with crescents (FGN)(5 cases), acute tubulo-interstitial diseases (ATID)(8 cases) and lipoid nephrosis with tubulo-interstitial nephritis (LN)(19 cases). FGN and ATID possibly represent a hypersensitive reaction of predominantly humoral (FGN) or cellular (ATID) mechanisms. These types of reaction are also seen to occur with the use of various drugs (most commonly with penicillin type antibiotics). LN on the other hand is rarely, if ever, seen with any drugs but NSAIDs and therefore seems to be a characteristic change for NSAIDs and possibly related to the inhibition of renal prostaglandin synthesis by NSAIDs. NSAIDs-associated renal dysfunction is mainly observed in patients of an increased use of NSAIDs with ineffective circulatory plasma volume (advanced age, cardiovascular disease, overweight and hypovolemia of various causes).
