α-Lipoic acid increases the viability of nephrocytes and elevates sulfane sulfur level in plasma of patients with chronic kidney disease

The results revealed that the viability of HEK293 cells was significantly decreased by hypoxic conditions, while ALA administered during hypoxia increased the viability to the level observed in normoxic conditions. Studies performed in plasma of CKD patients after ALA supplementation suggested that ALA did not affect the parameters of oxidative stress, while significantly increased the level of reactive sulfane sulfur in both ND and PD patients suffering from CKD. The results suggest that ALA can exert nephroprotective effects which are related to sulfane sulfur production.
