Analysis of liver biopsy specimens showed that SARS-CoV-2 might have led to liver damage. This study aimed to evaluate the role of selected hepatokines and myokines in the development and progression of COVID-19. Seventy patients with laboratory-confirmed COVID-19 and 20 healthy volunteers were enrolled in the study. Irisin, pentraxin 3, fetuin-A, and FGF-21 serum concentrations and biochemical parameters were assessed using an immunoenzymatic method with commercially available enzyme immunoassay (EIA) or enzyme-linked immunosorbent assay (ELISA) kits. Serum fetuin-A concentrations were significantly decreased in COVID-19 patients compared to healthy volunteers. The serum concentration of FGF-21 was significantly increased in obese COVID-19 patients compared to overweight ones. Moreover, the FGF-21 level was higher in COVID-19 patients diagnosed with metabolic syndrome than in patients without metabolic syndrome. PTX3 concentration was higher in COVID-19 patients with higher HOMA-IR values than those with lower HOMA-IR values. COVID-19 patients with HOMA-IR ≤3 and >3 had significantly lower fetuin-A levels than the control group. Irisin concentration was significantly decreased in the HOMA-IR ≤ 3 COVID-19 subgroup when comparing with the control group. Lower levels of fetuin-A observed in COVID-19 patients despite higher HOMA-IR, CRP, and ferritin levels, pneumonia, patients requiring ICU care suggests that fetuin-A deficiency predisposes to more severe COVID-19 course. Upregulated pentraxin 3 may be used as a potential predictor of COVID-19 severity.

Abstract Endometriosis is a gynaecological disorder characterized by increased number and activation of peritoneal macrophages and release of macrophage-derived cytokines and growth factors. The aim of our work was t(5 study the level of neopterin and interleukin (TL)-10 in peritoneal fluid and serum of women with endometriosis in relation to stage of disease. Concentrations of neopterin and IL-10 were measured by enzyme linked immunosorbent assay in PF and serum of 58 women; 43 with endometriosis and 15 without endometriosis. In our study present of neopterin in PF of women with endometriosis whereas neopterin could not be detected in the control group. Neopterin serum concentrations were significantly higher in affected women compared with control. Significantly increased neopterin concentrations were observed in peritoneal fluid and serum of women with advanced endometriosis. The mean peritoneal fluid and serum IL-10 concentrations were significantly higher ainong studied women than control. In women with early endometriosis, significantly increased concentration of IL-10 in peritoneal fluid and serum was observed. In conclusions, both increased concentrations of neopterin and IL-10 in the peritoneal fluid and serum suggest an important role of these Compounds in pathogenesis of endometriosis and indicate an enhanced macrophage activity in this disease.

BACKGROUND: The role of immunological disorders in the development of atopic dermatitis (AD) is currently beyond doubt. AIMS: Changes in the serum levels of IL-4, IL-10 and IL-13 in patients with atopic dermatitis (AD) after UV therapy combined with standard drug treatment have been studied. MATERIALS AND METHODS: The study included 80 patients with moderate to severe AD and 80 healthy volunteers. The patients with AD received a course of 311 nm UVB phototherapy combined with standard drug therapy. Serum IL-4, IL-10 and IL-13 levels were determined through enzyme-linked immunosorbent assay (ELISA). RESULTS: In the studied sample, patients with AD were found to have statistically significantly higher serum levels of IL-10 and IL-13 compared with healthy volunteers of the control group. Serum IL-10 level was 18.3 pg/ml in patients with AD and 13.2 pg/ml in those of the control group; the level of IL-13 was 15.8 pg/ml and 11.5 pg/ml, respectively; after the course of 311 nm UVB, serum IL-10 and IL-13 levels in patients with AD decreased (IL-10 by 27.8% and IL-13 by 12.5%). IL-4 values did not differ significantly in patients with AD and those in the control group, being 0.06 pg/ml and 0.05 pg/ml, respectively; after the course of phototherapy, serum IL-4 levels remained unchanged and were equal to 0.05 pg/ml. CONCLUSION: The results obtained confirm the assumptions about the significant role of IL-10 and IL-13 in the mechanisms of AD regulation and pathogenesis and demonstrate the anti-inflammatory efficacy of phototherapy (311 nm UVB) in patients with severe and moderate AD.

Objective. To determine the blood serum 2-microglobulin and 2-macroglobulin concentration in patients undergoing renal replacement therapy (programmed hemodialysis) for the diagnosis of uremic pancreatitis and / or destructive pancreatitis. Materials and methods. The study involved 52 patients admitted to the Surgical Unit of Astrakhan "RZhD-Medicine" Hospital and City Clinical Hospital № 3. The blood serum 2-microglobulin and 2-macroglobulin concentration was analyzed in patients admitted on an emergency basis with suspicion of uremic pancreatitis and destructive pancreatitis, who receive renal replacement therapy (programmed hemodialysis). The control group included 50 outpatients undergoing renal replacement therapy (programmed hemodialysis). The study did not include patients with suspected pancreatitis who were not receiving renal replacement therapy. The period of the study is 20192021. Results. The concentration of blood serum 2-microglobulin is statistically higher than normal in all patients, who had received renal replacement therapy (programmed hemodialysis) in anamnesis. The most statistically high concentration of 2-microglobulin was revealed while studying patients with uremic pancreatitis (n = 34), and was (30.0 2.75 mg/l) compared with the blood serum concentration in patients with destructive pancreatitis (8 0.51 mg / l). The concentration of 2-macroglobulin was statistically lower in destructive pancreatitis (n = 18) and was 615 161 mg/l compared with uremic pancreatitis (980 216 mg/l). In the control group of outpatients (n = 50) receiving renal replacement therapy (programmed hemodialysis), no statistically significant blood serum concentrations of 2-microglobulin and 2-macroglobulin were found. Conclusions. A clear dependence of the concentration of 2-microglobulin and 2-macroglobulin on the severity of uremic pancreatitis and destructive pancreatitis was established. Statistically high values of 2-microglobulin concentrations were obtained in patients with uremic pancreatitis, and the 2-macroglobulin level was statistically low in destructive pancreatitis.

Background: Asthma severity differs according to gender; in adult women, there is higher prevalence and severity of asthma than in men, and it coincides with changes in sex hormones. Recently, a new phonotype of asthma has been identified that appears after menopause, and it may be associated with decreased estrogen levels. Our goal was to study the 17β-estradiol (E2) concentrations in the blood and airways of women affected by asthma onset after menopause, evaluating its possible role in the severity of the disease. Methods: We enrolled 33 consecutive women with a diagnosis of postmenopausal asthma, recruited from the outpatient pulmonary clinic: 18 with severe (SA) and 15 with mild-to-moderate (MMA) asthma. We also included 30 age-matched healthy menopausal women as controls (HS). All subjects enrolled underwent blood and sputum collection (IS), and E2 concentrations were determined in plasma and sputum supernatant samples using an enzyme-linked immunosorbent assay (ELISA) kit. Results: Significantly higher serum concentrations of E2 were found in postmenopausal SA compared to MMA and HS, respectively (33 ± 5.5 vs. 24 ± 6.63 vs. 7.79 ± 1.54 pg/mL, p < 0.05). Similar results were found in the IS: significantly higher levels of E2 were detected in patients with postmenopausal SA compared with MMA and HS, respectively (0.34 ± 0.17 vs. 0.26 ± 0.13 vs. 0.07 ± 0.06 pg/mL, p < 0.05). We found positive correlations between IS E2 concentrations and sputum neutrophil levels in SA group (ρ = 0.52, p < 0.05). Conclusions: Our findings showed the possibility to measure E2 in the airways, and it has increased in postmenopausal asthmatic patients, especially in those with SA. Airways E2 levels may serve as a suitable biomarker of postmenopausal SA to help to phenotype SA patients with neutrophil inflammation.

Gestational diabetes mellitus (GDM) is considered to be one of the most frequent medical complication observed among pregnant women. The role of adipokines in the pathogenesis of GDM remains strictly unknown. Different adipokines have been studied throughout gestation, and they have been proposed as biomarkers of GDM and other pregnancy-related complications; however, there is no biomarker reported for GDM screening at present. The aim of this study was to evaluate serum nesfatin-1 and vaspin levels in GDM and non-GDM women, to characterize the correlation between these adipokines, and to assess the potential role of circulating adipokines in the prediction of risk of gestational diabetes mellitus. Serum concentrations of nesfatin-1 and vaspin were measured in 153 women with GDM, and in 84 patients with uncomplicated pregnancy by enzyme-linked immunosorbent assay (ELISA) kits, according to the manufacturer’s instructions. Circulating levels of nesfatin-1 and vaspin were significantly lower in the GDM group than in the control group. Nesfatin-1 levels were negatively correlated with vaspin levels. The results of this study point out the possible role of nesfatin-1 and vaspin as potential novel biomarkers for the prediction and early diagnosis of GDM. Further studies are necessary to evaluate the influence of nesfatin-1 and vaspin on glucose metabolism in the early stages of GDM.

1. Reocclusion is still a significant complication after percutaneous transluminal coronary angioplasty. The injury of coronary arteries resulting from PTCA plays an important role in the pathophysiology of both abrupt closure and late restenosis after an initially successful procedure. Cytokines play a pivotal role in the accumulation of circulating blood cells at the endothelium and are known to regulate their interaction with the vessel wall. 2. To obtain further information about this interaction, serum concentrations of soluble endothelial leukocyte adhesion molecule 1 (sELAM-1), leucocyte endothelial cell adhesion molecule 1 (sL-selectin), intercellular adhesion molecule 1 (sICAM-1), interleukin 2 receptor (sIL-2R) and interleukin 8 (IL-8) detected by enzyme-linked immunosorbent assay were monitored in 30 consecutive patients referred for elective PTCA. Fifteen patients who underwent elective coronary angiography without PTCA served as controls. 3. All patients underwent successful first PTCA. Within 24 h the serum concentrations of sELAM-1 increased gradually from 21.7 (SD 7.1) to 48.2 (SD 8.6) ng/ml (P < 0.01); levels of sL-selectin rose from 982.1 (SD 128.7) to 1541.3 (SD 104.6) ng/ml after 48h (P < 0.01). Serum levels of IL-8 remained stable initially, but peaked at the end of the observation time of 72 h (9.4, SD 3.8, versus 16.1, SD 4.9 ng/ml; P < 0.05). A positive correlation was found between the number of dilatations and the rise in these parameters (P < 0.01). No significant changes were found in the serum concentrations of sICAM-1 and sIL-2R after PTCA or in any of the parameters in patients after coronary angiography. 4. We conclude that PTCA induces a significant rise in the concentration of certain adhesion molecules in serum. Thus, we provide preliminary data on the potential role of cytokines for blood cell-endothelium interaction after PTCA. Further investigations and larger numbers of patients are needed to clarify the role of circulating cytokines for endothelial injury and restenosis after PTCA.

Abstract Background. Indirect epidemiologic evidences have suggested that viral infections may represent an important risk factor in the etiological mechanisms of B cell precursor lymphoblastic leukemia (BpALL), specially common-ALL. Parvovirus B19 (PvB19) is associated with aplastic crisis, thrombocytopenia, and congenital anemia. Five studies have reported the concurrent PvB19 infection in pediatric ALL. In a view of the increasing contest about the direct or indirect role of viral infection in ALL, we evaluated the possible associations of PvB19 and herpes virus 6 (HHV-6) in samples from children suffering from hematological disorders in order to estimate the magnitude of risk of association with common-BpALL. Material and Methods. A total of 659 blood samples were randomly selected to perform the serological tests. They were part of diagnostic samples referred to CPq-INCA-Rio de Janeiro, Brazil, from 2002–2006, for diagnostic purpose. Blood samples were exclusively selected from patients in whom samples were taken at the time of the onset of sickness. The diagnosis of BpALL was based on immunophenotyping methods according to EGIL criteria. The presence of serum antibodies for PvB19 and HHV-6 were determinate by enzyme-linked immunosorbent assay. Statistical analyses were conducted using SPSS for Windows 11.0. All p values were two sided; p&lt;0.05 was considered statistically significant. Results. Common-ALL (n=176) and non-leukemic samples (n=107) considered as control group were stratified according to age-groups at diagnosis. Age distribution was: less than 2 years (15.5%); 2–6 years-old (46.0%), and 7–12 years-old (17.7%). The estimation of associated risk PvB19 IgG+ antibodies with common-BpALL was OR 0.53 95% CI (0.52–0.54); whereas HHV-6 IgG was OR 2.36, 95% CI (1.08–5.17). Conclusions. We find out a higher prevalence of HHV-6 antibodies in patients with common-BpALL, suggesting an association between HHV-6 infection e common-BpALL in Brazilian children. There is a long history in developed countries regarding the role of infections in leukemogenesis process. Further tests are necessary to confirm these results.

The aim of the present study was to verify the effects of fish oil and a soya-based product on inflammatory markers and endothelial function measured by NO in women with the metabolic syndrome (MetS). A total of sixty-five women (mean age: 47·9 (sd9·98) years) were studied in a 90-d parallel, randomised design. A control group maintained their usual diet; the second group received 29 g/d of soyabean (kinako); the third group received 3 g/d of fish oiln-3 fatty acids; and the fourth group received fish oil (3 g/d) and kinako (29 g/d). Anthropometric, blood pressure (BP), inflammatory markers, anti-inflammatory marker (adiponectin) and NO concentrations were evaluated. In relation to the baseline values, the group that received fish oil and kinako concomitantly presented a statistically significant decrease in systolic BP (SBP;P < 0·05), whereas there was a significant decrease in diastolic BP (DBP) in the control group (P < 0·05), kinako group (P < 0·01) and fish oil group (P < 0·01) after 90 d. There was a significant increase in adiponectin (P < 0·01) and NO values (P < 0·05) after 90 d in the kinako and fish oil groups. Differences between treatment groups verified a significant decrease (P < 0·05) in DBP in the kinako group after 90 d when compared to the results obtained from the fish oil and kinako groups. In conclusion, the findings of increased serum adiponectin and NO metabolite levels after 90 d, both in the fish oil and soya groups, reinforce the importance of the influence of adiponectin and NO levels on BP decrease in patients with the MetS.

Background/Aims: The purpose of this study is to explore the immunoregulatory role of microRNA-21 (miR-21) targeting of the TLR4/MyD88 signaling pathway in macrophages in response to Bacillus Calmette-Guerin (BCG) infection. Methods: After infection with BCG, mouse RAW246.7 cells were assigned into control, BCG, miR-21 mimic + BCG, mimic-negative control (NC) + BCG, miR-21 inhibitor + BCG, inhibitor-NC + BCG, BCG + TAK242 (an inhibitor of the TLR4 signaling pathway), and miR-21 inhibitor + TAK242 + BCG groups. Western blotting and qRT-PCR were used to detect the expression of miR-21, TLR4 and MyD88. The levels of TNF-a, IL-6 and IL-10 were detected by enzyme-linked immunosorbent assay (ELISA). Cell viability was measured using an MTT assay. Cell apoptosis and necrosis rates were detected using flow cytometry. Results: Compared with the control group, miR-21 expression and levels of TNF-a, IL-6 and IL-10, as well as cell apoptosis and necrosis rates, were elevated, while expression of TLR4 and MyD88, as well as cell viability, were reduced in BCG infection groups. Compared with the BCG group, miR-21 expression was increased in the miR-21 mimic + BCG group but decreased in the miR-21 inhibitor + BCG and miR-21 inhibitor + TAK242 + BCG groups. The expression of TLR4 and MyD88, as well as the cell viability, were decreased, while levels of TNF-a, IL-6 and IL-10, as well as cell apoptosis and necrosis rates, were increased in the miR-21 mimic + BCG and TAK242 + BCG groups. The opposite trends were found in the miR-21 inhibitor + BCG group. Compared with the TAK242 + BCG group, the miR-21 inhibitor + TAK242 + BCG group had higher expression of TLR4 and MyD88 as well as higher cell viability and lower levels of TNF-a, IL-6, IL-10, cell apoptosis and necrosis rates. However, the miR-21 inhibitor + TAK242 + BCG group exhibited the opposite trends when compared with the miR-21 inhibitor + BCG group. Conclusion: Our results suggest that miR-21 can negatively modulate the TLR4/MyD88 signaling pathway, resulting in decreased cell viability, increased cell apoptosis and increased levels of inflammatory factors following BCG infection in macrophages.

Abstract Background: Asprosin, a newly identified adipokine, is pathologically increased in individuals with insulin resistance. However, the available evidence on the association of asprosin and type 2 diabetes mellitus (T2DM) status is still scarce. Therefore, this study aimed to determine the relationship between serum concentrations of asprosin and T2DM status . Methods: This observational study was performed based on 194 adults (97 newly diagnosed T2DM and 97 healthy individuals). Anthropometric and biochemical variables were determined in all participants . Serum concentrations of asprosin were measured using enzyme-linked immunosorbent assay (ELISA). Results: In patients with T2DM, the serum concentrations of asprosin were significantly higher than the healthy controls (4.18 [IQR: 4.4] vs. 3.5 [IQR: 1.85], P< 0.001). The concentrations of asprosin were significantly correlated with body mass index (BMI) and fasting blood glucose (FBG) in healthy subjects and with BMI, FBG, hemoglobin A1c (HbA1c), homeostatic model assessment of insulin resistance (HOMA-IR), and quantitative insulin check index (QUICKI), triacylglycerol (TAG) and total cholesterol/ high-density lipoprotein cholesterol (TC/HDL-C) ratio in the T2DM group. In fully adjusted model, the odds ratio (OR) of T2DM with serum concentrations of asprosin was approximately 1.547 (95% CI 1.293-1.850, P< 0.001) compared to the control group . Multiple stepwise regression analysis indicated that FBG and HOMA-IR were independently associated with asprosin in T2DM. Conclusion : Our findings indicated that serum concentrations of asprosin are increased in patients with T2DM. Also, asprosin is correlated with insulin resistance and TC/HDL-C ratio (atherosclerotic risk factor of cardiovascular diseases) in patients with T2DM.
