Abstract Various laboratory markers are utilized in general practice to detect inflammation, and procalcitonin (PCT) has also been routinely measured in many patients as a marker of bacterial infection and sepsis. An increase in PCT starts before an increase in C-reactive protein (CRP), and PCT level is useful not only for the diagnosis of bacterial infection, sepsis, as an indicator of the severity and prognosis of systemic inflammatory diseases, and is also useful for determination of the response to individual treatment. PCT is a precursor of calcitonin and PCT is not produced in a healthy state but is produced by various tissues in septic conditions. Since there are many patients with elevated levels of PCT due to nonbacterial causes, the levels of serum PCT have been apt to be used for a marker for the early detection of not only bacterial infection but also many inflammatory and/or febrile disorders including fever of unknown origin (FUO) in the clinical setting of general medicine. Here we attempted to clarify the differences and similarities of inflammatory markers for a clinical setting. We retrospectively reviewed 359 patients in whom serum PCT had been measured. According to our earlier study, the patients were categorized into 7 groups: bacterial, non-bacterial infection, non-specific inflammation, neoplasm, connective tissue disease (CTD), drug-induced diseases, and unidentified causes. Data for 332 PCT-positive cases including cases of bacterial infection (20.5%), non-specific inflammation (20.8%), neoplasm (9.9%), CTD (8.4%), and non-bacterial infection (7.2%) were used for analysis. Serum PCT level was highest in the bacterial infection group (1.94 ng/ml) followed by the non-specific inflammatory group (0.58 ng/ml) and neoplastic diseases group (0.34 ng/ml). Of note, serum PCT level was positively correlated with serum levels of C-reactive protein (R2=0.39), soluble interleukin-2 receptor (sIL-2R; R2=0.48), and ferritin, plasma level of D-dimer level and white blood cell count, whereas it was negatively correlated with serum albumin level (R2=0.27), hemoglobin concentration and platelet count. The result of the strongly positive correlation with serum level of sIL-2R suggested that an increased serum PCT level may indicate not only an inflammatory state but also a neoplastic state such as malignant lymphomas in the diagnostic process of various inflammatory disorders in a clinical setting of general practice for diagnosing febrile conditions.

Objective: Only a few studies have investigated variations of different markers for inflammatory processes during the physiological menstrual cycle. The results are conflicting, particularly concerning the correlation between the marker leptin and steroid hormones. The aim of the study was to investigate the inflammatory markers C-reactive protein (CRP) and leptin in the serum of healthy, normally ovulating women and to correlate these with each other and with the hormones of the gonadal axis. A cycle-dependence of the markers studied would imply an exact timing of the blood sampling for clinical needs. Design: Observational study investigating the two inflammatory markers CRP and leptin in relation to the hormonal pattern of the gonadal axis during the normal cycle. Methods: Ovulatory cycles of 36 healthy, young, normo-androgenic women, having a normal body mass index were evaluated. Serum concentrations of leptin and CRP, as well as of follicle-stimulating hormone, luteinising hormone, 17β-oestradiol, progesterone, prolactin (PRL) and free testosterone were measured every 1–2 days during one full cycle. Results: Serum levels of leptin and CRP behaved differently during ovulatory cycles, with higher concentrations for leptin only during certain phases. Significant correlations were found in the follicular phase between leptin and PRL and leptin and free testosterone. Conclusions: Leptin levels change during the menstrual cycle. Leptin levels are more stable on cycle days 1–5 than later in the cycle. For precise cycle-independent measurements, these fluctuations have to be taken into account. There is no similar cyclic pattern for CRP.

AbstractEarly bacterial infection (BI) identification in resource-limiting Emergency Departments (ED) is challenging, especially in low- and middle-income counties (LMIC). Misdiagnosis predisposes to antibiotic overuse and propagates antimicrobial resistance. This study evaluates new emerging biomarkers, secretory phospholipase A2 group IIA (sPLA2-IIA) and compares with other biomarkers on their performance characteristic of BI detection in Malaysia, an LMIC. A prospective cohort study was conducted involving 151 consecutive patients admitted to the ED. A single measurement was taken upon patient arrival in ED and was analysed for serum levels of sPLA2-IIA, high-sensitive C-reactive protein (CRP), procalcitonin (PCT), neutrophil percentage (N%), and lactate. All biomarkers’ performance was compared for the outcomes using area under the receiver operating characteristic curve (AUROC), sensitivity, and specificity. The performance of sPLA2-IIA (AUROC 0.93 [95% CI: 0.89–0.97]; Sn 80% [95% CI: 72–87]; Sp 94% [95% CI: 81–89]) was the highest among all. It was comparable with high-sensitive CRP (AUROC 0.93 [95% CI: 0.88–0.97]; Sn 75% [95% CI: 66–83]; Sp 91 [95% CI: 77–98]) but had a higher Sn and Sp. The sPLA2-IIA was also found superior to N%, PCT, and lactate. This finding suggested sPLA2-IIA was recommended biomarkers for BI detection in LMIC.

BackgroundPoint-of-care C-reactive protein (CRP) testing is widely accepted in Dutch general practice for adult patients with acute cough, but GPs’ perceptions of its use in children with suspected lower respiratory tract infection (LRTI) are unknown. Knowledge of these perceptions is important when considering broadening its indication to use in children.AimTo explore the perceptions of Dutch GPs of the addition of point-of-care CRP testing to the diagnostic evaluation of children, and compare these to their perceptions of use in adults.Design & settingA qualitative study in general practice in the Netherlands.MethodSemi-structured interviews were held with 11 GPs. Interviews were analysed using open coding and a thematic approach.ResultsGPs’ perceptions of the addition of point-of-care CRP testing to diagnostic process in children with suspected LRTI differ from their perceptions of this in adults. Five themes were identified: patient characteristics; vulnerability of the child; clinical presentation; availability of evidence; the impact of the procedure; and use of point-of-care CRP testing as a communication tool.ConclusionDifferences between the perceptions of using point-of-care CRP testing in children and adults need to be addressed when considering the possible implementation of this diagnostic instrument.

Abstract Objective To analyse the correlations between olfactory psychophysical scores and the serum levels of D-dimer, C-reactive protein, ferritin, lactate dehydrogenase, procalcitonin and neutrophil-to-lymphocyte ratio in coronavirus disease 2019 patients. Methods Patients underwent psychophysical olfactory assessment with the Connecticut Chemosensory Clinical Research Center test, and determination of blood serum levels of the inflammatory markers D-dimer, C-reactive protein, ferritin, lactate dehydrogenase, procalcitonin and neutrophil-to-lymphocyte ratio within 10 days of the clinical onset of coronavirus disease 2019 and 60 days after. Results Seventy-seven patients were included in this study. D-dimer, procalcitonin, ferritin and neutrophil-to-lymphocyte ratio correlated significantly with severe coronavirus disease 2019. No significant correlations were found between baseline and 60-day Connecticut Chemosensory Clinical Research Center test scores and the inflammatory markers assessed. Conclusion Olfactory disturbances appear to have little prognostic value in predicting the severity of coronavirus disease 2019 compared to D-dimer, ferritin, procalcitonin and neutrophil-to-lymphocyte ratio. The lack of correlation between the severity and duration of olfactory disturbances and serum levels of inflammatory markers seems to further suggest that the pathogenetic mechanisms underlying the loss of smell in coronavirus disease 2019 patients are related to local rather than systemic inflammatory factors.

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.

Abstract Serum levels of sIL-2R represents the total amount of activated T-lymphocytes in tumor infiltrating lymphocytes of cancer tissues and metastatic organ sites. Most malignant diseases overexpress sIL-2R in comparison to non-malignant controls. Immunomodulatory effect of IL-2 therapy on interferon (IFN), tumor necrosis factor alpha (TNF-a) production, nuclear factor kappa–b (NFkb) in vivo and in vitro and on the expression of sIL-2R in Human Immunodeficiency Virus – Waldenstrom Macroglobulinemia (HIV-WM) patients with IgM is not well defined. We present a 42 year old female with HIV, CD4-343/cu mm, viral load (VL) of >100K (persistently elevated VL), hypercoagulable state, serum viscosity >3 centpoises, IgM level of >1 gram with serum free light chain kappa/lambda ratio elevated as well as IgG and IgA on immunofixation studies. She was treated initially with BPD (Biaxin, Pentoxifylline, Dexamethasone) with partial response and with poor paraprotein parameter response. Her HAART regimen consisted of ritonavir base therapy. When dexamethasone was weaned off and prednisolone therapy started, greater than 50% reduction of paraprotein (IgM) occurred over 4–6 weeks. We measued serum sIL-2R, C-reactive protein (CRP), throughout treatment over 12 weeks. The serum sIL-2R level significantly decreased from 21,513.274 pg/ml to 5,424.779 pg/ml (normal 3,592.9 – 9,734.5 pg/ml). The C-reactive protein normalized and IgM was now 0.211 gram and within normal limits as well as serum viscosity. CONCLUSIONS: The suppression and modulation therapy of CRP gene transcription with manipulation of NFkb/IKKb with ritonavir based HAART and BPD-Pred with normalization of sIL-2R, CRP, and IgM paraprotein in HIV-WM patients may have an independent effect on prognosis and maintenance therapy. Serum sIL-2R levels may serve as a useful marker in evaluating HIV-WM disease, stage for stage and monitoring disease progression.

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.
