CLINICAL DIAGNOSTIC VALUE OF AUTOANTIBODIES IN THE DIAGNOSIS OF AUTOIMMUNE LIVER DISEASES

We are studied the 15 patients with autoimmune liver diseases and 36 patients without autoimmune pathology found the diagnostic value of antinuclear and antimitochondrial autoantibodies (AMA-M2) tests, and antibodies to asialoglycoprotein receptor (anti-ASGPR). Based on the ROC analysis showed that the diagnostic sensitivity and diagnostic specificity of AMA-M2 was 73% and 100% and for anti-ASGPR – 60% and 77%, respectively. Therefore, the test for anti-ASGPR in autoimmune diseases of the liver showed no advantages over standart tests, and its using in clinical practice requires clarification

Clinical value of oral fluid chemokines in chronic periodontitis

Activation of cytokine network is one of the key mechanisms in immunopathogenesis of chronic periodontitis (CP), a common dental disease. Therefore, the study of the proteomic (including cytokine) profile of saliva is not coincidentally considered among global research areas in periodontology. However, the existing data on the contents of cytokines / chemokines in oral fluid (OF) in CP are contradictory. This ambiguity of the results can be associated both with a variety of methodological approaches to the cytokine determination, and with different severity of CP in the studied cohorts of patients. Moreover, recent systematic reviews and meta-analyses show that clinical value of chemokines in CP is also not yet determined thus indicating a need for future research in this area.The aim of this study was to assess clinical and diagnostic value of some chemokines from oral fluid in chronic mild periodontitis. The work was based on a study of 18 patients diagnosed with mild chronic periodontitis (MCD-10 K05.3) and 12 practically healthy volunteers with relatively intact periodontal tissue. The diagnosis was based on standard clinical and radiological criteria. In all cases the levels of 8 chemokines were determined using multiparametric fluorescence analysis with magnetic microspheres (xMAP technology, Luminex 200, USA). Statistical analysis was carried out by methods of non-parametric statistics. To determine the predictive value of the test, ROC analysis was performed.It has been shown that CP is accompanied by increased levels of CXCL1 (5.5-fold), CXCL8 (8.1-fold), CXCL12 (3.5-fold), CCL2 (2.7-fold). At the same time, the level of other chemokines did not change significantly. There was a lack of correlations between individual parameters in the group of patients with CP, in contrast to the control group, thus, probably reflecting disturbed mechanisms of “balance” regulation of chemokines. By means of ROC analysis, highly sensitive biomarkers of chronic mild periodontitis were identified. The diagnostic sensitivity and diagnostic specificity were for CXCL1 (91 and 75%, respectively), CXCL8 and CXCL12 (95 and 75%), CCL2 (82 and 75%). The data obtained indicate that the salivary chemokines CXCL1, CXCL8, CXCL10, CXCL12, CCL2 can be considered potential biomarkers of mild chronic periodontitis

Serum nesfatin in overweight and obese children

BACKGROUND: Obesity is one of the most common children diseases. In present time it is being actively studied the natural hormones role in the pathogenesis of obesity. AIMS: To determine the relationship between serum nesfatin level with impaired lipid metabolism in school age children with overweight and obesity. MATERIALS AND METHODS: The study included children with overweight and obesity («case») and healthy children with normal body mass («control») aged 9 to 15 years. All children were determined by concentration in cholesterol blood and its factions, apoA-1, apoB. Enzyme-linked immunosorbent assay (Bio Human Nesfatin Enzyme Immunoassay Kit). RESULTS: Groups of patients with overweight and obesity (n = 53) and healthy children (n = 31) were comparable by age and sex. In obese children, a significant decrease in the level of nesfatin-1 was revealed compared with the group with normal body weight. In cases of children obesity there is a marked decrease in the concentration of nesfatin-1 in serum, especially expressed in the dyslipidemia presence. The nesfatin-1 level are negatively correlated to BMI and body fat content. CONCLUSIONS: The obtained data suggest that along with the known key role of nesfatin in the regulation of eating behavior and appetite, it also affects anthropometric indicators, primarily associated with the accumulation of excess fat mass. Based on the data obtained, nesfatin-1 should be considered as a possible marker for the development of obesity in children

Сhange in pletelet parameters in patients with liver cirrhosis

The research is devoted to the study of the platelets parameters in patients with liver cirrhosis (LC). 208 patients was examined. Platelet counts (PLT), mean platelet volume (MPV), platelet distribution width (PDW), plateletcrit (PCT) were assessed in these people. It was established that thrombocytopenia at the initial stage had hyperdestructive type. This pathology in late stages had hypoproductive type. We identified differences in platelet parameters in patients with LC, depending on their severity, may play a crucial role in accurate diagnosis verification, laboratory monitoring and selection of optimal conservative treatment strategies.Данное исследование посвящено изучению тромбоцитарных показателей пациентов при циррозе печени (ЦП) различной степени тяжести. Обследовано 208 человек, у которых оценивали количество тромбоцитов(PLT), средний объем тромбоцитов (MPV), анизоцитоз (PDW) и тромбокрит (PCT). В результате исследования установили, что на начальной стадии цирроза печени тромбоцитопения имела характер гипердеструктивного типа, а уже на поздних стадиях приобрела гипопродуктивный генез. Выявленные различия в тромбоцитарных параметрах у пациентов с ЦП в зависимости от степени тяжести могут играть решающую роль в точной верификации диагноза, в лабораторном мониторинге и подборе оптимальных консервативных стратегий лечения
