[Asymmetries in the serum ceruloplasmin concentration of patients with spondylogenic lumbosacral radiculitis].

The levels of ceruloplasmin in the serum of blood taken from the veins of the back side of the foot were determined in 66 patients with the radicular syndrome of lumbar osteochondritis and in 7 normal subjects (control). In the patients, the level of ceruloplasmin was significantly elevated, especially on the side of the pain syndrome and, hence, Lasegue's sign was also more pronounced. In patients without pain lateralization, an increase in ceruloplasmin levels was symmetrical. In a protracted course of the pain syndrome and at the end of the treatment the ceruloplasmin concentrations were decreased.
