Glutathione (GSH) is an important regulator of intracellular redox homeostasis. In the brain, glutathione is considered a major antioxidant, which is also found at high concentrations in the extracellular environment. Altered GSH balance in plasma, blood and cerebrospinal fluid (CSF) has been observed in several disorders suggesting that an impaired antioxidant function is part of the pathophysiology. The aim of the present study was to investigate a possible relationship between glutathione in plasma and CSF. Blood samples were collected from 26 healthy male volunteers at 8a.m., noon, 4p.m. and 8 p.m. At 8a.m. the following morning, blood was drawn and three 6-ml fractions of CSF were collected by lumbar puncture. In CSF, a disrupted gradient was found showing the highest glutathione concentration in the second compared to the first and third fraction (P<0.002). Moreover, correlation and regression analyses between glutathione in plasma and CSF revealed an association between the third fraction CSF and plasma glutathione 8 p.m. the day before lumbar puncture. Thus, if carefully standardised due to the disrupted gradient in CSF, it might be possible to estimate glutathione levels in CSF by analysing plasma in healthy males.
