Possible role of vitamin A and E deficiency in human idiopathic lithiasis

The purpose of our study is to compare the status of vitamin A and E enters a group of male patients aged 30–40 years and having idiopathic lithiasis in the other whose origin of the lithiasis is awarded to a hypercalciuria and/or hypercalciuria and/or hyperoxaluria. Reference values were established from a normal subjects aged 30–40 years and having no history of nephrolithiasis. Our results showed that the mean levels of vitamin A was significantly lower in idiopathic renal stone-formers than metabolic stone-formers (p < 0.001). Compared to control group, the status of vitamin A was found lower only in idiopathic renal stone patients (p < 0.05). On the contrary, the mean levels of vitamin E were found similar in the two patient groups, but significantly lower compared to control group. These results suggested that idiopathic renal stone genesis could be generated by vitamin A deficiency. [Copyright &y& Elsevier]
