Sažetak
Endemic nephropathy (EN) is a chronic renal disease present as an endemic in Brodska Posavina, Croatia. The aim of the study was to assess the possible role of fumonisins, i.e. mycotoxins produced by Fusarium moniliforme, as causative agents for EN. Fumonisins inhibit ceramide synthase, the enzyme of de novo synthesis of sphingolipids, which leads to an increase in the sphinganine/sphingosine ratio. In the present study, a modified method has been used for the determination of the sphinganine/sphingosine ratio in human serum and urine of healthy subjects and EN patients from the endemic area. Free sphingoid bases, sphinganine and sphingosine, were obtained by base hydrolysis. Afterwards, precolumn ortho-phtaldialdehyde derivatisation, HPLC separation and quantification by fluorescence detection were performed. The results thus obtained pointed out to a sphingolipid metabolism impairment, which may have been induced by fumonisins, or fumonisins-like mycotoxin. As statistically significant differences were recorded in the subjects not yet affected with EN, an impairment in the metabolism of sphingolipids might be considered as an eary indicator of EN.
