Background: The mortality rate of pancreatic cancer (PC) is equal to its incidence and the majority of PC patients die within a few months of diagnosis. Therefore, a search for new biomarkers useful in the diagnosis and prognosis of PC is ongoing. Objectives: The aim of our study was to compare the utility of CXCR2 and CXCR4 in the diagnosis and prediction of PC with classical tumor marker (carcinoembryonic antigen, CEA) and marker of inflammation–C-reactive protein (CRP). Patients and Methods: The study comprised 64 subjects — 32 PC patients and 32 healthy volunteers. Serum concentrations of tested proteins were analysed using immunological methods. Results: Serum CXCR2 and CXCR4 concentrations, similarly to those of CEA and CRP, were significantly elevated in PC patients compared to healthy controls. Moreover, concentrations of CXCR4 were significantly correlated with CXCR2 and CRP levels, while CRP concentrations were correlated with CXCR2 and CEA levels. The diagnostic sensitivity and the predictive value for negative (PV−ve) results for CXCR4 were similar to those of CEA and higher than those of CXCR2 and CRP, while the area under the ROC curve (AUC) for CXCR4 was the highest among all tested proteins (CXCR2, CEA, CRP). Moreover, serum CXCR2 was found to be a significant predictor of PC risk. Conclusions: CXCR4 is a better candidate for a tumor marker than CXCR2 in the diagnosis of PC, while serum CXCR2 is a significant predictor of PC risk.

Idiopathic granulomatous mastitis (IGM) is a rare inflammatory breast disease mimicking breast cancer. Limited research has been conducted on the application of serum biomarkers. This study aims to investigate the association of serum biomarkers with disease severity in patients with IGM. From November 2011 to March 2020, medical records of patients with IGM were reviewed. Serum cytokine levels were measured in patients and healthy controls between July 2018 and March 2020. A total of 41 patients with histologically proven IGM were found. Serum interleukin (IL)-6 level was significantly higher in patients with IGM (n = 11) than healthy controls (n = 7). Serum IL-6 and C-reactive protein (CRP) levels were significantly higher in patients with severe disease than mild and moderate disease. Serum IL-6 (Spearman’s ρ = 0.855; p < 0.001) and CRP (Spearman’s ρ = 0.838; p = 0.001) levels were associated with time to resolution. A higher serum CRP level was associated with a longer time to resolution (B = 0.322; p < 0.001) in multiple linear regression analysis. Serum IL-6 and CRP levels can be used as biomarkers for the evaluation of disease severity in IGM. IL-6 may play a crucial role in the immunopathology of IGM.

<b><i>Background:</i></b> Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease. An important role of innate immune dysregulation in the pathogenesis of HS has been highlighted. S100A7 (psoriasin) is an innate, antimicrobial protein that exerts proinflammatory and chemotactic action. <b><i>Objectives:</i></b> The objective of the study was to investigate serum concentrations of S100A7 in individuals with HS as compared to healthy controls. Further, we evaluated the expression of S100A7 in lesional HS skin as compared to perilesional (clinically uninvolved) HS skin and normal skin. <b><i>Methods:</i></b> Serum concentrations of S100A7 were evaluated with a commercially available ELISA kit. The expression of S100A7 in the skin was assessed using qRT-PCR and immunofluorescence staining. <b><i>Results:</i></b> We found increased expression of S100A7 in lesional HS skin as compared to perilesional HS skin (<i>p</i> = 0.0017). The expression of S100A7 in lesional HS skin was positively associated with serum C-reactive protein concentration and the severity of disease according to Hurley staging. The serum concentration of S100A7 in individuals with HS was decreased as compared to healthy controls and patients with psoriasis. <b><i>Conclusions:</i></b> Upregulated in lesional HS skin, S100A7 may enhance the inflammatory process and contribute to the HS pathogenesis.

Background:The onset of the disease in young and middle age is typical for rheumatic diseases (RDS), but most studies on osteoporosis were conducted in patients (pts) older than 50 years, which included postmenopausal women.Objectives:To assess bone mineral density (BMD), fracture frequency and the factors associated with low BMD in premenopausal women with RDs.Methods:160 women (median age, 36 [29; 43] years): 120 pts with RDs (43 rheumatoid arthritis (RA), 53 systemic sclerosis (SSc) and 24 psoriatic arthritis (PsA)) and 40 age-matched healthy controls were enrolled in the study. We performed a dual-energy X-ray absorptiometry (DXA, Hologic Discovery A, USA) to measure BMD in lumbar spine, femoral neck and total hip. BMD decreasing grade was evaluated by the Z-score <-2SD. All pts were interviewed using a unified questionnaire including assessment of daily dietary calcium intake. Serum vitamin D, C-reactive protein and erythrocyte sedimentation rate (ESR) measurements were done.Results:25% pts with RDs and only 8% healthy controls have low BMD (p=0.02). RA, SSc and PsA pts had low BMD in 37%, 21% and 13%, respectively, that was more often than in healthy women (p=0.004, p=0.046 and p= 0.081, respectively). 9,3% RA pts and 7,5% SSc pts had low energy fractures. BMD of RDs pts in all areas of measurement demonstrated a direct correlation with height, weight, body mass index, and serum vitamin D concentration and an inverse correlation with the cumulative dose of glucocorticoids. Also, proximal femur BMD inversely correlated with RDs duration. BMD of femoral neck and total hip inversely correlated with C-reactive protein level in SSc pts. In RA women we found a direct correlation between lumbar spine and femur neck BMD and ESR.Conclusion:25% of premenopausal women with RDs had reduced BMD and needed monitoring and osteoporosis prevention, while 9.3% pts with RA and 7.5% women with SSc needed anti-osteoporotic treatment.Disclosure of Interests:None declared

Abstract Background Myocardial strain assessed with cardiovascular magnetic resonance (CMR) feature tracking can detect early left ventricular (LV) myocardial deformation quantitatively in patients with a variety of cardiovascular diseases, but this method has not yet been applied to quantify myocardial strain in patients with atrial fibrillation (AF) and no coexistent cardiovascular disease, i.e., the early stage of AF. This study sought to compare LV myocardial strain and T1 mapping indices in AF patients and healthy subjects, and to investigate the associations of a portfolio of inflammation, cardiac remodeling and fibrosis biomarkers with LV myocardial strain and T1 mapping indices in AF patients with no coexistent cardiovascular disease. Methods The study consisted of 80 patients with paroxysmal AF patients and no coexistent cardiovascular disease and 20 age- and sex-matched healthy controls. Left atrial volume (LAV), LV myocardial strain and native T1 were assessed with CMR, and compared between the AF patients and healthy subjects. Biomarkers of C-reactive protein (CRP), transforming growth factor beta-1 (TGF-β1), collagen III N-terminal propeptide (PIIINP), and soluble suppression of tumorigenicity 2 (sST2) were obtained with blood tests, and compared between the AF patients and healthy controls. Associations of these biomarkers with those CMR-measured parameters were analyzed for the AF patients. Results For the CMR-measured parameters, the AF patients showed significantly larger LAV and LV end-systolic volume, and higher native T1 than the healthy controls (max P = 0.027). The absolute values of the LV peak systolic circumferential strain and its rate as well as the LV diastolic circumferential strain rate were all significantly reduced in the AF patients (all P < 0.001). For the biomarkers, the AF patients showed significantly larger CRP (an inflammation biomarker) and sST2 (a myocardium stiffness biomarker) than the controls (max P = 0.007). In the AF patients, the five CMR-measured parameters of LAV, three LV strain indices and native T1 were all significantly associated with these two biomarkers of CRP and sST2 (max P = 0.020). Conclusions In patients with paroxysmal AF and no coexistent cardiovascular disease, LAV enlargement and LV myocardium abnormalities were detected by CMR, and these abnormalities were associated with biomarkers that reflect inflammation and myocardial stiffness.

Abstract Introduction C-reactive protein (CRP) and procalcitonin (PCT) are widely used as markers of inflammation and infection in general population and in chronic hemodialysis (HD) as well. However, in dialysis (D) patients, serum CRP and PCT levels may be elevated even in the absence of inflammatory or infectious disease and diagnostic process is a challenge in such cases. We studied HD patients' laboratory profile concerning CRP and PCT. Subjects and Methods We studied 25 stable HD patients, M/F=22/3, aged 68(44-89) years, dialyzed thrice weekly for 55(6-274) months with a dialysate flow rate of 700 ml/min, with a residual daily diuresis less than 200 ml, Kt/V values of 1,44±0,3 and no signs of infection. Patients were classified in two groups. Group A included 10 patients on pre-dilution online hemodiafiltration (HDF). Group B consisted of 15 patients on conventional HD with low-flux polysulfone membrane. Twenty healthy subjects formed a control group C. Serum CRP and PCT levels were measured in duplicate in A and B groups before and at the end of mid-week dialysis sessions and also in C group. Results Pre-D serum CRP values in the total of patients were higher than those in healthy controls (10,89±19,29 vs 2,54±1,28 mg/L-p=0,004). Compared with group C, pre-D CRP values were higher only in B group (15,98±24,54 mg/L-p=0,001) but not in A group (4,09±3,33 mg/L-p=NS). There was a significant difference in pre-D serum CRP values between A and B groups (p=0,028). At the end of D session serum CRP values showed a tendency to increase in both groups A (5,16±4,81 mg/L) and B (17,00±27,00 mg/L) but differences were not significant. Pre-D serum PCT values in the total of patients were higher than those in healthy controls (0,82±0,9 vs 0,29±0,55 ng/ml-p&lt;0,001). Compared with group C, pre-D PCT values were higher in both A group (0,52±0,15 ng/ml-p&lt;0,001) and B group (1,01±1,13 ng/ml-p=0,006). There was no significant difference in pre-D serum PCT values between A and B groups (p=0,261). At the end of D session serum PCT values decreased in A group (0,32±0,11 ng/ml-p&lt;0,001) and increased in B group (1,12±1,21 ng/ml-p=0,014). Conclusions In patients on both conventional low-flux HD and online HDF pre-D serum CRP and PCT levels were higher than those in healthy subjects. Dialysis modality and membrane flux did not affect post-D serum CRP values, but post-PCT values decreased in online HDF. PCT usefulness might be limited in dialysis with high-flux membranes. Cut-off values have to be established for both markers to eliminate confusion in diagnosis of inflammatory and infectious diseases in hemodialyzed patients.

Aim. To assess the interrelations in the dynamics of immune, clinical, and functional parameters among patients with myocardial infarction (MI) and early fluvastatin administration. Material and methods. The study included 129 men, aged from 42 to 67 years (mean age 57 years): 99 MI patients and 30 healthy controls. In all participants, clinical, biochemical, functional, and immune parameters were assessed, with comparisons between healthy individuals vs. MI patients, as well as between MI patients taking fluvastatin (80 mg/d) vs. MI patients not receiving this medication. Results. In men with MI, chronic systemic inflammation was manifested in elevated levels of C-reactive protein, interleukin (IL) 1β, IL8, tumor necrosis factor α, immunoglobulin A and G, and complement components, as well as in decreased levels of IL1 receptor antagonist, CD 3, CD 4, CD 16, and CD 4/CD 8, compared to healthy controls. Early fluvastatin administration (first post-MI hours) was associated with reduced severity of immune disturbances and systemic inflammation. Conclusion. In MI patients, early fluvastatin administration is associated with a significant reduction in systolic and diastolic blood pressure levels, compared to controls, as well as with a substantial increase in exercise capacity at 2 months.

Objectives. To assess inflammatory serum markers including serum proinflammatory cytokines, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) according to the clinical inflammatory activity of patients with hidradenitis suppurativa (HS). Patients and Methods. Seventy-four patients with HS were studied based on the Hidradenitis Suppurativa-Physician Global Assessment (HS-PGA) score and Hurley staging system. Proinflammatory cytokines were measured using a multiplex cytokine assay. Twenty-two healthy volunteers were recruited. Results. Serum interleukin- (IL-) 6, IL-23, soluble tumour necrosis factor alpha (TNF-α) receptor I (sTNF-RI), CRP, and ESR were different in the patients with HS compared with those in the healthy controls (P<0.05). The levels of IL-1β, IL-6, IL-8, IL-10, IL-12p70, IL-17A, sTNF-RII, CRP, and ESR were significantly elevated according to inflammatory activity based on HS-PGA scores (r>0.25, P<0.05). The levels of IL-6 (r=0.53, P<0.001), CRP (r=0.54, P<0.001), and ESR (r=0.60, P<0.001) were especially well correlated with clinical inflammatory activity based on HS-PGA scores. The levels of IL-6, IL-8, sTNF-RI, sTNF-RII, CRP, and ESR were significantly elevated according to Hurley staging system. Conclusions. Serum proinflammatory cytokines, CRP, and ESR are increased in relation to the clinical inflammatory activity of patients with HS compared with healthy controls. Serum IL-6, CRP, and ESR are effective biomarkers for evaluating the severity of HS.
