It has been shown that adhesive molecules are involved in inflammatory diseases of the lungs such as bronchial asthma. The purpose of the study was to measure and establish possible difference in serum levels of soluble ICAM-1 in 42 atopic patients (patients with allergic rhinitis and patients with bronchial asthma) in comparison with 28 patients without atopy (patients with asthma without rhinitis); whether there is a difference in sICAM-1 levels between groups of 26 patients with allergic rhinitis and asthma in comparison with group of 16 patients with allergic rhinitis only and also in comparison with 10 healthy controls. Results of the study have substantiated statistically significant difference in sICAM-1 levels between all groups of patients in comparison to healthy control, but no statistically significant difference in sICAM-1 levels between patients with and without atopy (Z=-1.738) or between patients with allergic rhinitis and bronchial asthma in comparison with group of patients with allergic rhinitis only (Z=0.00). ICAM-1 is an important marker of inflammation in patients with allergic rhinitis as well as in those with bronchial asthma. Atopic status does not influence differences in sICAM-1 levels. Although mean sICAM-1 levels were higher in patients with allergic rhinitis and bronchial asthma (312.71 ng/mL) in comparison with mean sICAM-1 levels in patients with allergic rhinitis only (279.69 ng/mL), no statistically significant difference was noted in sICAM-1 levels between these groups of subjects, i.e. asthma itself did not contribute to statistically significant increase of sICAM-1 levels.

Abstract Background The aim was to determine the level of inflammatory cytokines, eosinophil cationic protein and IgE in allergic rhinitis (AR) patients. Subjects and methods Blood samples were taken from 88 AR patients and 88 healthy controls (HC). Each sample was analysed for eosinophil counts by flow cytometry, IgE by ECLIA, ECP, IL-17, and IL-33 by using ELISA test. Results There was no significant difference between AR patients and the control group in age and gender. Levels of eosinophils, IgE, ECP, IL-17, IL-33 and the total symptom scores were significantly higher in AR patients than the HC (P = 0.0001). Serum ECP correlated with IL-17 (P = 0.041, r = 0.42), IL-33 (P = 0.0001, r = 080), and IgE levels (P = 0.017, r = 0.45) in the R patients. There was no correlation between IL-17 and IL-33. There was a correlation between symptom scores and eosinophils (P = 0.026, r = 0.52), and IgE (P = 0.001, r = 0.60) in the patients. No correlation was observed between symptom scores and ECP, IL-17, and IL-33 in the AR patient. Conclusions Patients with AR have significant higher serum levels of ECP, IL-17, and IL-33 than healthy controls. This indicates that these markers could be used to in order to diagnose AR and to monitor disease. Inhibitory molecules to IL-17 and IL-33 may be considered as novel treatment strategies.

Objective. High mobility group box 1 (HMGB1) is a late inflammatory factor participating in the pathogenesis of various autoimmune and inflammatory diseases. In the current study, we analyzed the association between serum levels of HMGB1 and clinical features of AS patients before and during treatment.Methods. Serum HMGB1 was detected in 147 AS patients and 61 healthy controls using ELISA. We evaluated the association between HMGB1 and extra-articular manifestations as well as disease severity indices. Among these AS patients, 41 patients received close follow-up at 1, 3, and 6 months after treatment. This group comprised 25 patients treated with anti-TNF-αbiologics and 16 patients receiving oral NSAIDs plus sulfasalazine.Results. The serum HMGB1 of AS patients was significantly higher than in healthy controls and positively correlated with BASDAI, BASFI, ASDAS-ESR, ASDAS-CRP, ESR, and CRP, but not with HLA-B27, anterior uveitis, and recurrent diarrhea. There was no significant difference between patients with radiographic damage of hip joints and those without. We observed that serum HMGB1 paralleled disease activity after treatment.Conclusion. Serum level of HMGB1 is higher in AS patients, and to some extent, HMGB1 can reflect the activity of AS and be used as a laboratory indicator to reflect the therapeutic response.

Abstract Context Sclerostin is an inhibitor of Wnt-β-catenin signaling to regulate bone formation. Circulating sclerostin levels were reported to be elevated in patients with X-linked hypophosphatemia (XLH), and sclerostin antibody (Scl-Ab) has been shown to increase bone mass and normalize circulating phosphate levels in Hyp mice. However, circulating sclerostin level in acquired hypophosphatemic patients with tumor-induced osteomalacia (TIO) remains rare reported. Objectives This study was designed to evaluate serum sclerostin levels in TIO patients comparing them with age-, sex- matched healthy controls and XLH patients, and analyze correlation of circulating sclerostin with BMD and laboratory parameters. Design, Setting and Participants 190 individuals including 83 adult TIO patients, 83 adult healthy controls and 24 adult XLH patients were enrolled in this cross-sectional study. Main outcome measures Serum sclerostin levels were determined in TIO patients, healthy controls and XLH patients. Results TIO patients (43 male and 40 female) aged 44.3 ± 8.7 (mean ± SD) years had lower levels of circulating sclerostin than healthy controls (94.2 ± 45.8 vs 108.4 ± 42.3 pg/mL, p = 0.01) with adjustment for age, gender, BMI and diabetes rate. Sclerostin levels were positively associated with age (r = 0.238, p = 0.030). Male patients had higher sclerostin level than female patients (104.7 ± 47.3 vs 83.0 ± 41.8 pg/mL, p = 0.014) and postmenopausal patients had higher tendency of sclerostin level than premenopausal patients (98.4 ± 48.8 vs 71.6 ± 32.3 ng/ml, p = 0.05). Sclerostin levels were positively associated with BMD of L1-4 (r = 0.255, p = 0.028), femoral neck (r = 0.242, p = 0.039) and serum calcium (r = 0.231, p = 0.043). TIO subgroup patients (n=24, 35.9 ± 7.3 years old) comparing with age-, sex-matched adult XLH patients and healthy controls revealed significant difference of sclerostin levels (XLH, TIO and healthy control were 132.0 ± 68.8, 68.4 ± 31.3 and 98.6 ± 41.1 pg/mL, respectively, p < 0.001). Conclusions Circulating sclerostin levels were decreased in TIO patients but increased in XLH patients, which might be result of histological abnormality and bone mass.

Abstract Background Breast cancer is the most common cancer among women and one of the most important causes of death among them.Angiogenesis is an important step for primary tumor growth, invasiveness, and metastases. Angiopoietins are well-recognized endothelial growth factors that are involved in angiogenesis associated with tumors. Aim To explore the diagnostic significance of serum angiopoietin-2 (Ang-2) in breast cancer and to evaluate its prognostic efficacy through studying the degree of its association with the TNM staging of the disease. Patients and Methods This study was conducted on (35) Egyptian female patients who were diagnosed as breast cancer according to histopathological examination of breast biopsy (Group 1, Breast Cancer Patients) and (25) female patients with benign breast diseases (Group II, Pathological Control Patients), in addition to (20) age - matched apparently healthy, free mammogram, females serving as healthy controls (Group III, Healthy Controls). For all participants, measurement of serum Ang-2 was done using enzyme linked immunosorbent assay (ELISA) technique. Results A highly significant increased levels of Ang-2 was observed in breast cancer patients when compared to healthy control group (Z = 4.95, p < 0.01). However, no significant difference was observed in Ang-2 levels between breast cancer patients group and pathological control group (Z = 3.37, p > 0.05). No significant difference was detected in Ang-2 levels in relation to TNM stage and histological grade. No significant correlation was found between Ang-2 levels and serum levels of CA15-3, hormone receptors, HER2/new receptor status (p > 0.05, respectively). Conclusion This study revealed that Ang-2 serum levels were significantly increased in patient with breast cancer compared with healthy controls, indicating that high Ang-2 level is a promising non invasive biomarker for breast cancer diagnosis. However, no significant difference of Ang-2 levels was detected in relation of breast TNM staging in the population studied.

Background: Lung cancer screening is a challenge. Sputum cytology, chest X-ray, low dose computed tomography and other screening methods have not proved to be very effective. Serum biomarkers are a new hope in screening of lung cancer. The present study was planned to evaluate sensitivity and specificity of serum levels of amyloid A (SAA), soluble E- selectin (sE-selectin) and soluble E-cadherin (sE-cadherin) as lung cancer biomarkers.Methods: An observational and cross-sectional study comprised of three groups with 20 subjects each of proven lung cancer cases, patients with non-malignant respiratory diseases and healthy controls. Levels of SAA, sE-selectin and sE-cadherin were measured by solid phase sandwich ELISA. Individual and collective sensitivity and specificity of these biomarkers was analysed and cut off values calculated by receiver operating curves.Results: A statistically significant difference was found in the median levels (ng/ml) of SAA in patients of lung cancer, other non-malignant respiratory diseases, and healthy controls, the levels (Mean±SD) being 24980.50±6564.14,9961.10±2000.24 and 580.95±334.94 respectively in the three groups. A sensitivity of 80% and specificity of 55% was found when SAA levels of 1068 ng/ml were taken as cut off for screening of lung cancer. However, no significant difference was found in the serum levels of sE selectin and sE cadherin between the three groups. Moreover, significant association of biomarkers could also not be established with lung cancer when they were used in combination.Conclusions: In this preliminary report from India, SAA has been found to be a promising biomarker in screening for lung cancer.

Abstract Objective. It was previously demonstrated that cutaneous vasculitis, including IgA vasculitis and cutaneous arteritis (CA), is associated with the presence of IgM antibodies (Abs) against the phosphatidylserine/prothrombin complex (PS/PT). Recently, novel enzyme-linked immunosorbent assay kits for the detection of IgG and IgM anti-PS/PT (aPS/PT) Abs have become commercially available.Methods. The prevalence of serum IgG and IgM aPS/PT Abs in both cutaneous and systemic vasculitis was determined using these kits. In addition, to examine whether aPS/PT Abs were involved in the pathogenesis of cutaneous vasculitis, inbred wild-type rats were intravenously administered with a rat IgM class aPS/PT monoclonal Ab established previously or with rat immunoglobulins as controls. To express PS on the surface of vascular endothelium, these rats were given a subcutaneous injection of cell-free histones (250 µg/ml, 300 µl/site) 2 hours in advance. Results. Serum IgM aPS/PT Ab levels were elevated in patients with systemic vasculitis with skin involvement and CA compared to those in patients with systemic vasculitis without skin involvement and healthy controls. There was no significant difference in the serum levels of IgG aPS/PT Abs between the patients and healthy controls. Correspondingly, inbred wild-type rats intravenously administered with the aPS/PT monoclonal IgM Ab after appropriate priming—subcutaneous histone injection—developed cutaneous vasculitis. Some rats given rat IgM instead of the aPS/PT monoclonal Ab also developed cutaneous vasculitis, whereas vasculitis did not occur in rats given IgG or only priming by histones. Conclusion. IgM aPS/PT Abs could be involved in the pathogenesis of cutaneous vasculitis.

Various defects in platelet function have been reported as being associated with multiple myeloma. In 30 myeloma patients and 15 healthy controls, we investigated platelet survival using in vitro labeling of autologous platelets with 111indium-oxine and measuring the in vivo kinetics of the radioisotope. Significantly shortened platelet half- life in patients averaged 73 hours, while platelet half-life in the healthy controls averaged 107 hours. In myeloma patients, serum levels of thromboxane B2, beta-thromboglobulin, and platelet factor 4 were significantly elevated; aggregation indices were within the pathological range; platelet counts and spleen-liver indices, however, were comparable to those of the healthy control group. No statistical correlation was found between platelet half-life and paraprotein concentrations. Our findings suggest an initial--so far unexplained-- intravascular process of platelet activation and consumption that finally manifests in shortened platelet half-life. It seems that overt thrombocytopenia develops only when the compensatory capacity of the bone marrow finally becomes exhausted. Further studies should be able to elucidate the pathophysiologic processes involved.

Background/Aims: Although proton pump inhibitors (PPIs) remain a mainstay for the suppression of gastric acid secretion, long-term PPI use is associated with side effects. However, the genotoxicity associated with long-term PPI use is unclear.Materials and Methods: This prospective observational pilot study enrolled patients who had been on PPIs for >1 year and healthy controls from July 2015 to August 2016. The subjects completed self-report questionnaires pertaining to their drug and medical history, and only those with no medical history and a ≥2-year wash-out period (for drugs other than PPIs) were included. We collected peripheral-blood lymphocytes from long-term PPI users and healthy controls and analyzed the genotoxicity by using the cytokinesis-block micronucleus cytome assay; we also determined the fasting serum levels of pyridoxine, folate, cobalamin, and homocysteine.Results: Ten long-term PPI users and 40 healthy control subjects were enrolled. The median serum pyridoxine, folate, cobalamin, and homocysteine levels were not significantly different between the groups. The median frequencies of micronuclei (MNi), nucleoplasmic bridges (NPBs), and nuclear buds (Nbuds) per 1,000 binucleated cells, in long-term PPI users and healthy controls, were 30.3 and 16.3 (<i>P</i><0.005), 2.5 and 1.8 (<i>P</i><0.005), and 9.3 and 5.0 (<i>P</i><0.005), respectively. Even after adjustment for confounding factors, the OR of the MNi, NPBs, and Nbuds for long-term PPI users compared with healthy control subjects were 14.1 (<i>P</i><0.001), 2.0 (<i>P</i>=0.001), and 1.3 (<i>P</i>=0.3), respectively.Conclusions: Long-term PPI use was significantly associated with an increased risk of genotoxicity after adjustment for age, sex, body mass index, medical history, drug history, and the serum levels of vitamins.

Background: Butyric acid, a major short-chain fatty acid (SCFA), has an important role in the microbiota–gut–brain axis and brain function. This study investigated the role of butyric acid in treatment response in drug-naïve first episode schizophrenia.Methods: The study recruited 56 Chinese Han schizophrenia inpatients with normal body weight and 35 healthy controls. Serum levels of butyric acid were measured using Gas Chromatography-Mass Spectrometer (GC-MS) analysis at baseline (for all participants) and 24 weeks after risperidone treatment (for patients). Clinical symptoms were measured using the Positive and Negative Syndrome Scale (PANSS) for patients at both time points.Results: At baseline, there was no significant difference in serum levels of butyric acid between patients and healthy controls (p = 0.206). However, there was a significant increase in serum levels of butyric acid in schizophrenia patients after 24-week risperidone treatment (p = 0.030). The PANSS total and subscale scores were decreased significantly after 24-week risperidone treatment (p's &lt; 0.001). There were positive associations between baseline serum levels of butyric acid and the reduction ratio of the PANSS total and subscale scores after controlling for age, sex, education, and duration of illness (p's &lt; 0.05). Further, there was a positive association between the increase in serum levels of butyric acid and the reduction of the PANSS positive symptoms subscale scores (r = 0.38, p = 0.019) after controlling for potential confounding factors.Conclusions: Increased serum levels of butyric acid might be associated with a favorable treatment response in drug-naïve, first episode schizophrenia. The clinical implications of our findings were discussed.
