RESUMO
AIM: To study dynamic surface tension (DST) of blood and urine in SLE patients. MATERIALS AND METHODS: Clinical, immunological examinations, DST of blood and urine using computer tensiometers were made in 67 SLE patients aged 15 to 62 years. RESULTS: Changes in interphasic tensiograms in males and females were characterized regarding the course, activity of the pathological process and the presence of certain clinical symptoms. Effective therapy return to normal DST of the biological fluids. Correlations between interphasic tensiograms of blood, urine and levels of proteins, lipids, non-protein and inorganic surfactants and surface-inactive substances were established as well as relations of DST with biochemical composition of the biological fluids. CONCLUSION: The above diagnostic method may be useful for differential diagnosis, assessment of the clinical course, activity of the disease, control over effectiveness of the treatment.
