RESUMO
Background: During the last years the addiction rate remains stable high. While the neurochemical drug effect remains unclear. Aims: To analyze the changes of the idiotypic (аÐТ1) and anti-idiotypic (аÐТ2) autoantibodies to the neuroproteins S100, MBP, GFAP, NGF on the different stages of opium addiction and to indicate prognosis criteria of their effect. Materials and Methods: 70 patients (only men, aged 22−38) with diagnosis opium addiction underwent examination. According to the results of testing, we detected the intoxication in 24 patients, withdrawal in 24, and 22 patients were at remission stage of 21−28 days. The control group included only healthy people (n=18). The survey was focused on the rate detection of the idiotypic and anti-idiotypic IgG class antibodies in relation to the rate of neural proteins (S100, MBP, GFAP, NGF) in the serum with the IEA. Results: In patients with opium intoxication, we revealed statistical assurance in the rate of autoantibodies amount and their counterweights to the neural proteins rate between control and experimental groups. Only the rate of the аÐТ2 protein significantly decreased relatively to the MBP. In patients with abstinence, the rate of аÐТ1 to the MBP, GFAP (Ñ≤0,05) increased. The rate of аÐТ2 in relation to the GFAP and MBP also increased (Ñ≤0,05), at the same time it decreased in relation to the S100 and NGF (Ñ≤0,05). The autoantibodies amount at the remission stage corresponded to the amount at the intoxication stage. The comparative analysis of the patient groups with the different stages of opium addiction detected the identity criteria both in the intoxication and remission. We revealed statistical assurance in the rates of аÐТ1 to MBP and аÐТ2 to NGF in patients with intoxication and abstinence, and in the rates of аÐТ1 to GFAP, MBP, and аÐТ2 to GFAP (decreased in the remission) and to S100, MBP (increased in the remission) in patients with abstinence and at remission. Conclusion: Levels of idiotypic and anti-idiotypic antibodies to the neural proteins S100, MBP, GFAP, NGF (especially аÐТ2 to MPB) could be used as diagnostic factor and for accessing different states of opium addiction.
