ABSTRACT
Purpose : It has been reported that endothelin-1 can be associated with the development of cyclosporine A nephrotoxicity. Levels of endothelin-1 was assayed to determine the effect of cyclosporine A on the plasma and urine levels of this peptide. Method : Nine patients who were less than 15 years of age and were also diagnosed as steroid dependent minimal change nephrotic syndrome were included in this study. Assay of endothelin-1 was done before and 3 months after cyclosporine A treatment. The mean age of the patients was $8.3{pm}4.6$ years. Result : There was no significant differences in the plasma levels of endothelin-1 before and after 3 months of cyclosporine A treatment ($3.22{pm}0.39$ pg/mL vs. $3.84{pm}1.52$ pg/mL, P=0.64). Also there was no changes in the urine levels of endothelin-1 ($21.8{pm}5.8$ pg/mL vs. $20.3{pm}3.1$ pg/mL, P=0.30).
Conclusion : No significant changes of endothelin-1 levels were found with 3 months of cyclosporine A treatment. Further studies with longer durations will help clarifying the effect.
Key words: Cyclosporine A | Nephrotoxicity | Endothelin-1
