SUMMARY Introduction Cryoglobulins are single or mixed immunoglobulins that are subject to reversible precipitation at low temperatures. Objective The aims of this paper were: 1. Comparison of cryoglobulin positive (CP), cryoglobulin negative (CN) heroin addicts and the control group (CG) in terms of serum immunoglobulins IgG, IgA and IgM and complement components C3 and C4; 2. Comparison of CP and CN heroin addicts in terms of rheumatoid factor (RF) and circulating immune complexes (CIC); 3. Assessment of clinical manifestations in CP heroin addicts. Methods This is a comparative study of cases (outpatients) treated at the University Clinic of Toxicology in Skopje over 3.5 years, from January 2009 to June 2012. In this study 140 heroin addicts without HbsAg were examined, seronegative for HCV and HIV infections. They were divided into 2 groups: 70 CP and 70 CN heroin addicts. A previously designed self-administered questionnaire was used as a data source on participants. All heroin addicts underwent the following analyses: urea and creatinine in serum; creatinine in urine; proteinuria; 24-hour proteinuria; IgM, IgG, IgA, C3, C4 ; RF; CIC; creatinine clearance; ECG; toxicological analyses for opioids in a urine sample; cryoglobulins. In addition to these 2 groups, IgG, IgA, IgM, C3 and C4 were also examined in 70 healthy subjects (CG). Results The study showed that there was no statistically significant difference between CP, CN heroin addicts and CG regarding the concentration of IgA, IgG, IgM, C3 and C4, and between CP and CN regarding the concentration of CIC. There was significant difference between CP and CN regarding the concentration of RF. The following conditions were significantly more frequently manifested in CP than in CN heroin addicts: arthralgia, Raynaud’s phenomenon, respiratory difficulties, neurological disorders, manifested skin changes, hematuria, 24-hour proteinuria levels, and decreased renal clearance. Conclusion There were no differences in concentrations of IgG, IgA, IgM, C3, C4 and CIC, while there was a difference in concentration of RF between CP and CN heroin addicts. Clinical manifestations (arthralgias, Raynaud’s phenomenon, respiratory, neurologic, renal disorders and skin changes) were more common in CP heroin addicts.

<jats:p> 1,019 adult patients with terminal renal failure were treated with dialysis (D) in the first part of the year 2000 in the Republic of Macedonia. 1,010 patients (99%) were treated with chronic intermittent (maintenance) hemodialysis (HD) while nine patients (1%) were on continuous ambulatory peritoneal dialysis (CAPD). For the children, a special peritoneal dialysis program was developed; 509 patients per million of the population (PMP) were on dialysis. </jats:p><jats:p> The Republic of Macedonia is, therefore, among those central and eastern European countries with a higher PMP number in the treatment of end-stage renal disease, following Croatia, the Czech Republic and Slovenia. </jats:p><jats:p> The patients were treated at 18 Centers in a network of HD Centers at a distance of 30–50 km. from their place of residence in order to facilitate their access to treatment and to work. All patients who have had symptoms indicating need for treatment with D were accepted for treatment. The government payed all the expenses of the treatment and the salaries of the staff. 56% were male and 44% were female patients. The youngest patient was aged 9 and the oldest was 82 years old. There has been an increase in the age of the patients on D as well as an increase in their number. In 1993 we had 727 patients being treated with D, and now we have 1,019 with a constant increase in the number of patients with ESRD and a need for D and renal transplantation. Mortality per year at the different Centers ranged from 8–19% in 1999 and the average is 12%. </jats:p><jats:p> Glomerulonephritis (GN) – both primary and secondary – is the main cause of renal failure (RF) in some Centers up to 45%. Tubulo-interstitial disease follows GN. ADPKD patients constitute 9.4% with a difference among the Centers of 3–29%, and diabetic nephropathy is found in 10%, 5–15% in different Centers. 11–61% of patients have an unknown etiology. </jats:p><jats:p> 352 patients are on treatment with human recombinant erythropoietin (rhuEPO) – in some Centers up to 60%. The mode of application was subcutaneous and the initial dose is 20 U/kg body weight and the mean maintenance dose of EPO per patient weekly is 4,000 U. </jats:p><jats:p> The Cimino-Brescia arteriovenous fistula is being applied as a standard vascular access. The survival rate of our patients treated with maintenance HD at 5 years was 58%. CAPD and particularly renal transplantation are to be further developed as alternative methods in treating terminal renal failure. </jats:p>
