Purposes This study aimed at investigating the association between interleukin-6 (IL-6), interleukin-12 (IL-12), C-reactive protein (CRP), vascular endothelial growth factor (VEGF) and β-defensin-1 polymorphisms and the susceptibility to periodontitis in the Chinese population. Methods DNA was extracted from the blood samples of 532 healthy individuals and 122 chronic periodontitis (CP) patients enrolled in the study. The genes encoding IL-6, IL-12, CRP, VEGF and β-defensin-1 were amplified using PCR and digested with restriction enzymes. The protein expression of the abovementioned genes was determined by ELISA. Differences in the allele/genotype frequencies were assessed with the chi-square test. Results The frequencies of the C/C genotypes of IL-6, IL-12, and VEGF were higher in CP patients than healthy controls (66.3% vs 25.9%; 27.8% vs 19.9%; and 64.8% vs 52.1%, respectively). In the patients' group we also recorded frequencies of the A/A genotypes of CRP and VEGF higher than in healthy controls (63.1% vs 58.1% and 64.8% vs 35.2%, respectively). Protein production evaluated by ELISA demonstrated significant differences between CP patients and healthy controls for IL-6, IL-12, CRP, VEGF and β-defensin-1. Conclusions The genotypes of IL-6, IL-12, VEGF and β-defensin-1 and their protein productions were associated with CP in a Chinese population. Genotypes and serum levels of CRP were associated with CP, but alleles frequency showed no difference between CP patients and healthy controls.

Abstract Background and Aim: Sepsis is a life-threatening disease with high mortality, therefore establishing early diagnostic and finding reliable prognostic biomarkers is vital. We aimed to investigate the prognostic role, as a single value, of serum procalcitonin, C-reactive protein, serum lactate, platelets number and serum glucose level in septic patients, all measured in the first 24 hours after hospital admittance. Materials and methods: This retrospective study included 241 adult patients with sepsis, severe sepsis or septic shock. We use data from patients observation sheets. Data that were collected include: demographic parameters, comorbidities, necessity of mechanical ventilation and laboratory variables. We performed the statistical analysis with the chi square test for nonparametric data and to analyse the accuracy of prediction we used the receiver - operator curves with the level of significance set at p < 0.05. Results: From 241 patients with a median age of 68 years, 127 (52.69%) were male.113 patients had severe sepsis. 89 patients (36.9%) died and male had an increase mortality rate. Most cases were respiratory sepsis (45.20%). The highest mortality rate was in septic shock (51.2%). Procalcitonin, C-reactive protein and glucose serum level at admittance were not correlated with mortality. The serum levels of creatinine >1.67 mg/dL and serum lactate >1.9 mmol/L at admittance were correlated with mortality (p < 0.01). The cutoff value of 121×103/uL platelets number was also correlated with mortality (p < 0.01). Conclusions: Our findings suggest that serum creatinine, serum lactate and the platelets number could be used as prognostic markers in septic patients at admittance.

Background: Periodontitis (PD) is well-known chronic disease affecting the periodontal ligament and alveolar bone, Osteoarthritis (OA) is a chronic joint disease with compound reasons characterized by synovial inflammation, subchondral bone remodeling, also the formation of osteophytes, that cause cartilage degradation. Chronic periodontitis and osteoarthritis are considered widely prevalent diseases and related to tissue destruction due to chronic inflammation in general health and oral health. The aim of this study is todetermine the association of chronic periodontitis and osteoarthritits in patients by analysing tumor necrosis factor alpha TNFα and high sensitive c-reactive protein (hsCRP) in the serum. Materials and Method: A total of 80 patients of both sexes aged 35-50 years ,30 patients with osteoarthritis and moderate chronic periodontitis (CP+OA), 30 patients of both sexes aged 35-50 years with moderate chronic periodontitis alone (CP). And control group (C) of 20 healthy patients with healthy periodontium participated in this cross sectional study. we excluded the postmenopausal and pregnant woman from female patient and smoker patient also. All patients are free of medication and have good general health with no history of systemic disease. Participants with OA have documentation or radiographic imaging, consistent with degenerative arthritis in the absence of an inflammatory condition. Venous blood samples were drawn from each subject using pyrogen-free heparinized collection tubes. Tubes were centrifuged according to the manufacturer’s guidelines, then stored at -15°C till analyse. serum TNFα and hs CRP were measured using an enzyme-linked immunosorbent assay (ELISA). Results: A non-significant differences between studied group regarding serum level of hsCRP and TNF-α, as well as, the result revealed that the median of serum levels of hsCRP were little higher in chronic periodontitis with osteoarthritis group than chronic periodontitis group and control groups represent as 0.31, 0.29, and 0.24. Similarly, the medium serum level of TNFα was higher in chronic periodontitis with OAthan in other two groups (10.615, 10.533, and 9.682 respectively). The age and gender showed a non-significant difference between the groups Conclusion: The present study revealed that there’s a strong positive correlation between serum levels of hsCRP and TNFα in patients of all groups but there is no correlation between Osteoarthritis and chronic periodontitis.

Abstract Background: Although many studies have compared circulating IL-6 and CRP concentrations in periodontal patients and controls, a limited number of studies have compared systemic inflammatory markers at baseline and follow-up and also Data on whether periodontal therapy affects serum CRP levels are inconclusive. Aims and Objective: By the virtue of this study, an attempt was made to evaluate and compare the effect of non surgical periodontal therapy on serum C-Reactive Protein levels in Generalized chronic periodontitis patients. Material and Method: A total of thirty patients with Generalised chronic periodontitis, within the age range of 30-70 years, were selected and underwent non surgical periodontal therapy. Further, they were put on a two month follow up after post operative phase for evaluation and comparison of pre and post values. Results and Conclusion: The results of our study showed that non surgical periodontal therapy significantly reduces the serum levels of C-reactive protein along with other clinical parameters in patients with generalised chronic periodontitis.

Systemic lupus erythematosus (SLE) is a systemic autoimmune and inflammatory disease characterized by the polyclonal activation of T and B lymphocytes, production of autoantibodies, and formation of immune complex. We measured the serum level of myeloperoxidase (MPO) in patients with SLE (n = 97) and in healthy controls (n = 88) and assessed the correlation between the serum myeloperoxidase (MPO) levels and established disease-activity indexes. All patient samples with SLE analyzed showed higher serum levels of MPO than healthy controls. Higher MPO levels were observed in SLE patients with increased C-reactive protein (P=0.001), as well as in those with highly active disease (P<0.005). Our concluded is that the associations between MPO and the disease variables of SLE patients support a role for MPO in the inflammatory process of the disease.

Abstract Background Brain-derived neurotrophic factor (BDNF) is a neurotrophine that plays a key role in the regulation of both central and peripheral nervous system. Moreover, BDNF is secreted in multiple tissues and exerts systemic, autocrine, and paracrine effects in the cardiovascular system. Of importance, BDNF expression was enhanced in macrophages and smooth muscle cells in atherosclerotic coronary arteries and may be involved in thrombus formation. Thus, BDNF has been suggested as an important link between inflammation and thrombosis, potentially involved in the pathogenesis of acute coronary syndrome (ACS). Purpose In our study we aimed at assessing serum levels of BDNF in patients with ACS, evaluating differences according to clinical presentation [ST-segment elevation myocardial infarction (STEMI) vs. Non-ST-segment elevation ACS (NSTE-ACS)]. Moreover, we assessed the presence of optical coherence (OCT)-defined macrophage infiltrates (MØI) in the culprit vessel of ACS patients and evaluated their relationship with BDNF levels. Methods ACS patients were prospectively selected. Blood samples were collected at admission and serum levels of BDNF were subsequently assessed. Presence of OCT-defined MØI along the culprit vessel was assessed. Results 166 ACS patients were enrolled [mean age 65.3±11.9 years, 125 (75.3%) male, 109 STEMI, 57 NSTE-ACS]. Serum levels of BDNF were higher among STEMI patients compared with NSTE-ACS [median (IQR) 2.48 pg/mL (1.54–3.34) vs. 2.12 pg/mL (1.34–2.47), p=0.007], while C-reactive protein levels did not differ between the two groups. OCT assessment was performed in 53 patients and MØI were detected in 27 patients. Of importance, patients with MØI in the culprit vessel had higher levels of BDNF compared with patients without MØI [median (IQR) 2.23 pg/mL (1.38–2.53) vs. 1.41 pg/mL (0.93–2.07), p=0.023], while C-reactive protein levels did not differ between the two groups. Of note, at multivariate regression analysis BDNF levels were independent predictor of MØI [OR: 2.20; 95% CI (1.02–4.74), p=0.043]. Conclusions Serum levels of BDNF may reliable identify the presence of local macrophage inflammatory infiltrates in patients with ACS. Moreover, BDNF levels are higher in patients with STEMI compared with NSTE-ACS. Taken together, these data suggest that BDNF may represent an interesting link between local inflammatory activation and enhanced thrombosis in ACS.

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.

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.
