Objective: A comparative analysis of C-reactive protein (CRP) and procalcitonin concentration in blood serum and seminal plasma of healthy men and men with reduced concentration of sperm cells.Methods: 73 fertile men were examined. The experimental group included 36 patients with a reduced fertility; the comparison group (control) included 37 men with normal indicators of ejaculate composition. The concentrations of CRP and procalcitonin were determined by the method of enzyme-linked immunosorbent assay.Results: Differences in level of CRP between blood serum and seminal plasma in experimental and control groups occurred to be statistically significant in both groups. There was no correlation between these parameters. The concentration of procalcitonin was almost ten times higher in the seminal plasma than in the blood serum. In the experimen‑ tal group, it was significantly higher in ejaculate than in the comparison group. The concentration of CRP and procalcitonin did not correlate neither with the ejaculate volume nor with concentration or amount of sperm cells in it.Conclusions: The levels of CRP and procalcitonin in seminal plasma can indicate the fertility status of the ejaculate.

Purpose: C-reactive protein (CRP) and white blood cell (WBC) count are routine blood chemistry parameters in monitoring infection. Little is known about the natural history of their serum levels in conservative and operative spondylodiscitis treatment. Methods: Pre- and postoperative serum levels of CRP and WBC count in 145 patients with spondylodiscitis were retrospectively assessed. One hundred and four patients were treated by debridement, spondylodesis, and an antibiotic regime, 41 only with a brace and antibiotics. The results of the surgical group were compared to 156 patients fused for degenerative disc disease (DDD). Results: Surgery had a significant effect on peak postoperative CRP levels. In surgically managed patients, CRP peaked at 2–3 days after surgery (spondylodiscitis: pre-OP: 90 mg/dl vs. post-OP days 2–3: 146 mg/dl; DDD: 9 mg/dl vs. 141 mg/dl; p < 0.001), followed by a sharp decline. Although values were higher for spondylodiscitis patients, dynamics of CRP values were similar in both groups. Nonoperative treatment showed a slower decline. Surgically managed spondylodiscitis showed a higher success rate in identifying bacteria. Specific antibiotic treatment led to a more predictable decline of CRP values. WBC did not show an interpretable profile. Conclusion: CRP is a predictable serum parameter in patients with spondylodiscitis. WBC count is unspecific. Initial CRP increase after surgery is of little value in monitoring infection. A preoperative CRP value, and control once during the first 3 days after surgery is sufficient. Closer monitoring should then be continued. Should a decline not be observed, therapy needs to be scrutinized, antibiotic treatment reassessed, and concomitant infection contemplated.

Obesity and severe obesity are increasing serious health problems with an epidemic percentage in most countries. In Sleeve gastrectomy, a part of the stomach structure is removed, limiting its capacity by about two to three. A total of thirty blood samples were collected from patients with obesity and the result was compared with healthy person throughout the time from November 2019 to September 2020. Before sleeve gastrectomy and after more than 6 months of sleeve surgery, the sample was collected from the Medical City/Baghdad Teaching Hospital, the withdrawal was again taken at home to have pre and post sleeve gastrectomy, Patient age ranged between [20-46] years for obese patients and healthy control. Then the serum samples were obtained from patients and control group to screen for C-reactive protein by agglutination method. The result of the present study found that the positivity of CRP in pre-operation is higher than that of post-operative with high significance [P<0.005].

The aim is to study the conditions of appearance and the features of course of the acute coronary syndrome (ACS) in patients with normal rates of lipid metabolism and to assess the influence of additional risk factors (uinary acid, C-reactive protein, fibrinogen) on the development of atherosclerotic process by assessment of surrogate markers of atherosclerosis the thickness of intima-media complex (TIMC) of carotid arteries (СА), the presence of atherosclerotic plaque (AP) in CA, the value of ankle-brachial index (ABI)) in patients with ACS without dyslipidemia (DLP). Materials and methods. The study included 66 patients without DLP (50 men and 16 women, the mean age - 53,7±10,6 years) with ACS, divided in groups depending on its forms: 1 group – patients with instable angina (IA), 2 group – patients with myocardium infraction (MI) without ST segment elevation and 3 group – patients with MI with ST segment elevation. The level of serum acid, C-reactive protein, fibrinogen in blood serum were detected and ultrasound examination of СА with detection of CA TIMC, presence of atherosclerotic plaque and measuring of arterial pressure on upper and low extremities with ABI calculation was carried out. Results. Among examined patients MI with ST segment elevation was diagnosed in 33 persons (50,0%); MI without ST segment elevation – in 18 (27,3%) and IA – in 15 (22,7%). The complicated ACS was observed in 20 (30,30%) persons. The value of CA TIMC among patients with MI with ST segment elevation was reliably higher than in patients with MI without ST segment elevation (р<0,001), and ABI was reliably lower in persons with MI and ST segment elevation (р<0,05) and IA (р<0,05) than in patients with MI without ST segment elevation. Correlative analysis demonstrated the interconnection between the levels of inflammation indicators (C-reactive protein, fibrinogen) in the blood serum and the value of CA TIMC and ABI. Conclusions. The persons without DLP need additional examination (detection of C-reactive protein, fibrinogen levels in blood serum, ultrasound of CA and detection of ABI) for more precise evaluation of ACS risk.

Aim. To study the association of cytokine status with coronary atherosclerosis severity in patients with myocardial infarction (MI).Material and methods. Between 11.2018 and 07.2019, 92 patients hospitalized with MI in Perm Clinical Cardiology Dispensary were included in the study. The control group consisted of 23 patients with stable coronary artery disease. In addition to the standard examination, enzyme-linked immunosorbent assay was used to determine the levels of interleukins (IL)-6, -10, tumor necrosis factor alpha (TNF-α), C-reactive protein.Results. Significant increase in plasma IL-6, TNF-α and C-reactive protein levels in MI patients compared with the control group. The increase in the concentration of IL-6, TNF-α, as well as the IL-6/IL-10 ratio occurs in proportion to coronary atherosclerosis severity. A direct correlation of Gensini score with IL-6, TNF-α, and IL-6/IL-10 ratio was established.Conclusion. Further study of cytokine profile parameters in MI patients will help a clearer understanding pathogenesis of coronary artery atherosclerosis. An increase in concentrations of IL-6, TNF-α, and IL-6/IL-10 ratio is associated with an increase in coronary atherosclerosis severity and can be used in practice for its prediction.

Aim: To evaluate the effects of orally administered gadolinium orthovanadate GdVO4:Eu3+ nanoparticles (VNPs) on the course of chronic carrageenan-induced intestinal inflammation. Methods: Samples of small intestinal tissue were collected from four groups of rats (intact, after administration of VNPs, with carrageenaninduced intestinal inflammation, with carrageenan-induced intestinal inflammation orally exposed to VNPs) to assess the intestinal morphology and HSP90α expression. Levels of seromucoid, C-reactive protein, TNF-α, IL-1β and IL-10 were determined in blood serum. Results: Oral exposure to VNPs was associated with neither elevation of inflammation markers in blood serum nor HSP90α overexpression in the small intestine, i.e. no toxic effects of VNPs were observed. Carrageenan-induced intestinal inflammation was accompanied by higher levels of TNF-α and IL-1β, as well as HSP90α upregulation in the intestinal mucosa, compared with controls. Administration of VNPs to rats with enteritis did not lead to statistically significant changes in concentrations of circulating pro-inflammatory cytokines with the trend towards their increase. Conclusion: No adverse effects were observed in rats orally exposed to VNPs at a dose of 20 μg/kg during two weeks. Using the experimental model of carrageenan-induced enteritis, it was demonstrated that VNPs at the dose used in our study did not affect the course of intestinal inflammation.

In this trial, we evaluated the influence on plasma and salivary myeloperoxidase (MPO) levels of periodontal health, coronary heart disease (CHD), periodontitis, or both periodontitis and CHD. Clinical and periodontal parameters were collected from periodontitis patients (n = 31), CHD patients (n = 31), patients with both periodontitis and CHD (n = 31), and from healthy patients (n = 31) together with saliva and plasma samples. The median concentrations of salivary and plasma MPO were statistically higher in the CHD patients [plasma: 26.2 (18.2–34.4) ng/mg; saliva 83.2 (77.4–101.5) ng/mL, p < 0.01] and in the periodontitis plus CHD patients [plasma: 27.8 (22.5–35.7) ng/mg; saliva 85.6 (76.5–106.7) ng/mL, p < 0.001] with respect to periodontitis and control patients. Through a univariate regression analysis, c-reactive protein (CRP) and CHD (both p < 0.001) and periodontitis (p = 0.024) were statistically correlated with MPO in plasma. The multivariate regression analysis demonstrated that only CRP was statistically the predictor of MPO in plasma (p < 0.001). The multivariate regression analysis in saliva demonstrated that, regarding MPO levels the only predictors were CRP (p < 0.001) and total cholesterol (p = 0.035). The present study evidenced that subjects with CHD and periodontitis plus CHD had higher plasma and salivary levels of MPO compared to subjects with periodontitis and healthy controls.

The aim of this study was to investigate the predictive value of peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (Pin1) with C-reactive protein (CRP) and white blood cell (WBC) count for community-acquired pneumonia (CAP) in infants. A total of 84 hospitalized infants with CAP and 69 healthy infants were included in this study. The clinical manifestations and laboratory assay results of infants were recorded. Serum Pin1 level was estimated by enzyme-linked immunosorbent assay. The median serum Pin1 concentration in infants with CAP was significantly higher than that in controls (1.44 vs. 0.21 ng/mL, P < 0.0001). Receiver operating characteristic (ROC) curve analysis showed that the area under the ROC curve (AUC) of the combination Pin1, CRP and WBC (Pin1 + CRP + WBC, 0.943) was higher than Pin1, CRP, WBC alone or the combination of Pin1 and CRP ( P < 0.05). The sensitivity of Pin1 + CRP + WBC (94.0%) was higher than that of Pin1, CRP, WBC alone, or any two combined ( P < 0.05). Pin1 + CRP + WBC also had a high negative predictive value (91.4%). Moreover, serum Pin1 alone had a high specificity (97.0%) and excellent positive predictive value (96.6%) for infants with CAP, which were higher than WBC, Pin1 and WBC in combination, CRP and WBC in combination, and Pin1 + CRP + WBC ( P < 0.05). Therefore, serum Pin 1 was highly expressed in infants with CAP and can singly or in combination with CRP and WBC represent promising novel predictors for infants with CAP.

AbstractRheumatoid arthritis (RA) is characterised by painful, stiff and swollen joints. RA features sporadic ‘flares’ or inflammatory episodes—mostly occurring outside clinics—where symptoms worsen and plasma C-reactive protein (CRP) becomes elevated. Poor control of inflammation results in higher rates of irreversible joint damage, increased disability, and poorer quality of life. Flares need to be accurately identified and managed. A method comparison study was designed to assess agreement between CRP values obtained by dried blood spot (DBS) versus conventional venepuncture sampling. The ability of a weekly DBS sampling and CRP test regime to detect flare outside the clinic was also assessed. Matched venepuncture and finger lancet DBS samples were collected from n = 100 RA patients with active disease at baseline and 6 weeks (NCT02809547). A subset of n = 30 RA patients submitted weekly DBS samples over the study period. Patient demographics, including self-reported flares were recorded. DBS sample CRP measurements were made by enzyme-linked immunosorbent assay, and venepuncture samples by a reference immunoturbometric assay. Data was compared between sample types by Bland–Altman and weighted Deming regression analyses. Flare detection sensitivity and specificity were compared between ‘minimal’ baseline and 6 week sample CRP data and the ‘continuous’ weekly CRP data. Baseline DBS ELISA assay CRP measures yielded a mean positive bias of 2.693 ± 8.640 (95% limits of agreement − 14.24 to 19.63%), when compared to reference assay data. Deming regression revealed good agreement between the DBS ELISA method and reference assay data, with baseline data slope of 0.978 and intercept -0.153. The specificity of ‘continuous’ area under the curve (AUC) CRP data (72.7%) to identify flares, was greater than ‘minimal’ AUC CRP data (54.5%). This study indicates reasonable agreement between DBS and the reference method, especially at low to mid-range CRP values. Importantly, longitudinal CRP measurement in RA patients helps to clearly identify flare and thus could assist in remote monitoring strategies and may facilitate timely therapeutic intervention.Trial registration: The Remote Arthritis Disease Activity MonitoR (RADAR) study was registered on 22/06/2016 at ClinicalTrials.gov Identifier: NCT02809547. https://clinicaltrials.gov/ct2/show/NCT02809547.

Ultrasensitive detection of biomarkers is highly significant for disease prognosis and public health treatment. Despite wide acceptance in routine laboratory tests, the conventional enzyme-linked immunosorbent assay (ELISA) has been of limited use for early biomarker detection due to insufficient sensitivity and multiple long incubation time. Several nanoprobes have been introduced to circumvent the limitation, however, rapid, simple, and chemical-free nanoprobe synthesis and sensitive detection methods, particularly for ELISA, are still lacking. In this study, we have synthesized a gold nanoprobe, conjugated with multiple 6X-histidine (6X-his) peptide and nickel-horseradish peroxidase (Ni2+-HRP), for enhancing the colorimetric signal in ELISA. The developed nanoprobe has been tested for the detection of immunologically significant C-reactive protein (CRP) in ELISA format. The performance of designed probe is validated by testing standard and serum samples, and the detection limit of 32.0 pg/mL with R2 = 0.98 is confirmed. Furthermore, a comparative analysis of the developed nanoprobe was performed with ELISA developed on conventional guidelines, the proposed immunoassay showed an increase of 12-fold sensitivity for detecting CRP due to the high loading of 6Xhis peptide and binding of multiple Ni2+-HRP on a gold nanoparticle. Additionally, the proposed assay provides a simple, fast, and cost-efficient (not requiring multiple antibodies) detection of CRP with easy nanoprobe synthesis. Moreover, the developed Histag-HRP functionalized nanoconjugate immunoassay is flexible and can be applied to other biomarkers efficiently by using disease specific antibody.

Abstract Catatonia is a psychomotor syndrome defined by a constellation of predominantly motor symptoms. The aim of the present study was to determine whether recently admitted psychiatric patients with catatonia exhibited higher serum C-reactive protein (hs-CRP) levels compared to non-catatonic psychiatric patients and healthy controls (HCs). Recently admitted psychiatric patients were screened and evaluated for the catatonia syndrome using the Bush-Francis Catatonia Rating Scale and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). The study sample was formed by 150 individuals (39 male and 111 female), including 51 catatonic patients, 55 non-catatonic patients, and 44 HCs. Serum hs-CRP levels were processed with the enzyme-linked immunosorbent assay. Serum levels of creatine kinase (CK), adrenocorticotropic hormone (ACTH), immunoglobulin G (IgG), complement component 3 (C3), and complement component 4 (C4) were also determined. There was a significantly higher percentage of patients with high inflammatory levels (hs-CRP &gt; 3000ng/ml) in the catatonic (43.1%) than in the non-catatonic (14.5%) or HCs group (9.1%) (χ 2 =18.9, P &lt; .001). Logistic regression showed that catatonic patients had significantly higher hs-CRP levels compared to non-catatonic patients even after controlling for other clinical and laboratory variables (OR = 3.52, P = .015, 95% CI 1.28–9.79). Multiple linear regression analysis revealed that log-transformed hs-CRP was independently predicted by body mass index and log-transformed C4, ACTH, and Cortisol in catatonic patients. Findings of the present study suggest that catatonia is specifically linked to a higher level of systemic inflammation, not merely attributable to the overall psychopathology, or alterations in the stress level and complement system.
