Abstract

NTRODUCTION: Earlier studies have reported that heroin might cause the structural and antigen changes on numerous tissues, organs and subsequent development of autoimmune reactions (production of antibodies and creation of immune complexes) as a result the immunotoxic effect of heroin. The aims of our study were to: a) Evaluate CIC and antibeta2GP1 in heroin addicts; b) Correlate between the values of the obtained CIC and antibeta2GP1 (stratified by the duration and route of heroin application); c) Compare the CIC and antibeta2GP1 in heroin addicts and the control group and d) Assess the clinical importance of CIC and antibeta2GP1 in heroin addicts. PATIENTS AND METHODS: This was a cross-sectional study performed at the University Clinic of Toxicology and the Institute of Transfusiology, Skopje, Republic of Macedonia. Patients referred to the Clinic for clinical examinations who met the inclusion criteria were analyzed. Protocol for work was the following: 1.) detailed anamnestic data, 2.) a whole set of laboratory biochemical blood and urine analyses, 3.) examination with the Schiller's twelve-channel ECG; 4.) toxicological analyses for opioids in a urine sample; circulating immune complexes and 5.) antiphospholipid antibodies (antibeta2GP1, fractions: IgA, IgG, IgM). The obtained results were statistically analyzed. RESULTS: We included 37 heroin addicts and a control group of 27 healthy subjects. Male abusers predominated over female in--28 (76%) subjects; mean age being 26 +/- 5.06. The results which refer to the increased values of circulating immune complexes have shown a high statistically significant dominance of heroin addicts, in comparison with the control group (p < 0.01) and increased values above the reference ones of IgG antibeta2GP1, alone in the group of intravenous heroin abusers (p < 0.025). The mean duration of the heroin use in intravenous abusers was 6.21 +/- 3.25 years, whereas in those snorting heroin was 5.15 +/- 2.26 years. Duration of heroin application was in a positive correlation with IgG antibeta2GP1 (p = 0.35). CONCLUSIONS: Our data showed that heroin-dependent patients in our study had increased values of circulating immune complexes and changes in IgG and IgM antibeta2GP1 with significantly increased values of IgG antibeta2GP1 in the intravenous heroin abusers. The duration of heroin application is in direct proportional relationship with IgG antibeta2GP1. Heroin addicts had significantly higher values of circulating immune complexes and statistically significant difference in IgG antibeta2GP1, in comparison with the control group. Changes in the fractions of antibeta2GP1 and CIC suggest a possible relation with the somatic changes found in heroin addicts (i.e. thrombocytopenia, reduced renal clearance, etc).
