| Abstrakt: | The secondary hemophagocytic syndrome is a life-threatening condition characterized by non-specifc manifestations: systemic inflammatory reaction, cytopenia, liver affection, high content of ferritin in blood serum. One of manifestations of secondary hemophagocytic syndrome is decreasing of level of glycated ferritin in blood serum expressed in percentage of total level. The detection of glycated ferritin can be applied for a differentiated diagnosis with cli9nically similar conditions, including septic process. The purpose of study was to determine clinical value of easurement of glycated ferritin for diagnostic and differentiated diagnostic of secondary hemophagocytic syndrome. The analysis was applied to samples of blood serum and clinical data of patients with diagnoses of secondary hemophagocytic syndrome (n=40), severe sepsis (n=24), cytolitic syndrome (n=36) and healthy donors (n=40). The total content of ferritin is established using rbidimetric technique ("BioSystems", Spain). The glycated ferritin was calculated. To determine level of of glycated ferritin the glycated fraction of ferritin was precipitated using concanavalin A, polymerized with sepharose 4B ("GE Healthcare", USA). The normal values of glycated ferritin made up to 78.3%-87.1%. Under secondary hemophagocytic syndrome decreasing of content of glycated ferritin made up to 25.0 ± 18.7% and was signifcantly lower than under sepsis (47.0 ±17.7%, p<0.001) and cytolytic syndrome(63.5% ±18.7%, p<0.001). According the results of ROC-analysis, the area under curve was maximal as compared with other markers of secondary hemophagocytic syndrome, including total ferritin, triglycerides, fbrinogen. At decreasing of level of glycated ferritin lower than 30.4% the applied technique provides clinical sensitivity 69%, specifcity 94.3%, accuracy 86.9% in applying differentiating diagnosis of secondary hemophagocytic syndrome. At calculation of absolute content of non-glycated ferritin it was discovered that its values correlate with concentration of triglycerides, international normalized ratio, aspartataminotransferase, alaninaminotransferase and total bilirubin in patients with secondary hemophagocytic syndrome (p<0.05). Therefore, decreasing of level of glycated ferritin permits to diagnose secondary hemophagocytic syndrome with higher accuracy. Competing Interests: The authors declare no conflict of interest. |
