The Balkan endemic nephropathy (BEN) is an irreversible, chronic, tubulo-interstitial nephropathy described so far in several rural regions from the Balkan with an unknown aetiology. Both ochratoxin A (OTA) and aristolochic acid (AA) are considered responsible for BEN. This paper performed a comparison between the toxic effect of OTA and AA using a kidney cell line LLC-PK. OTA and AA decreased cell viability in a dose dependent manner. The dose dependent effect was observed for both toxins, the

For doses higher than 50µg/mL, the toxicity of AA was higher than the OTA cytotoxicity. A slight decrease of IL-8 was observed after 6h, for OTA, while AA slightly increases the IL-8 synthesis. After 24h, IL-8 synthesis was decreased by both toxins, AA having a more pronounced effect than OTA. IL-10 synthesis was not affected by the treatment of both toxins. In conclusion, both OTA and AA negatively affect LLC-PK cells viability and capacity to synthesize IL-8, with AA being more toxic than OTA for the highest concentrations used in this study.
