During the last two decades, an enormous effort has been made to discover biological markers of neuronal damage to effective response to therapy. Gangliosides a family of acidic glycosphingolipids are highly represented in the nervous system. Their spectra show considerable changes in pathological conditions. The complex of anti-ganglioside antibodies may be useful diagnostic and prognostic tool of markers for demyelination (GM1), neurodegeneration (GD1a)and(GM3) correlates with the loss of integrity of the blood brain barrier (BBB). Additionally, patients with renal failure may manifest a variety of neurologic disorders.Dialysis itself is associated with at least three distinct disorders of the central nervous system, including the dialysis disequilibrium syndrome, dialysis dementia, and progressive intellectual dysfunction. Our case studyinvolves a patient on dialysis, a 72-years old woman, as an example of long-term toxicity. She was on dialysis for 1,5 years. The values of IgG anti-GM1, anti-GD1a and anti-GM3 antibodies titers in the blood serum were detected by ELISA. Significantly elevated serum IgG anti-GM1 antibodies titers were detected in our patient. The value of the titer of IgG antibodies against GM1 showed the presence of weak demyelination, increasing with dialysis treatment but not neurodegeneration. On the other hand, other biomarkers were indicative of the preserved integrity of the BBB since IgG titers of antiGD1a and anti-GM3 antibodies were in norm.The patient had many signs that show and prove symptoms of encephalopathy.Neurologic findings in the patients with uremic encephalopathy (UE) range from normal to a comatose state. Neurologic diseases which are specifically related to uremia and/or dialysis occur with increased frequency in patients with end-stage renal disease on chronic hemodialysis. These include subdural hematoma, electrolyte disorders, vitamin deficiencies, drug intoxication, hypertensive encephalopathy, and acute trace element intoxication. Our observations show that there is a relationship between kidney problems and central nervous system (CNS).
