    Elevated eosinophil count was shown to be associated with the development of cholesterol embolization syndrome, a potentially life-threatening condition, after catheter-based procedures. We investigated the association between stages of chronic kidney disease (CKD) and the absolute eosinophil count (AEC) among cardiac patients. CKD stages were determined solely on the estimated glomerular filtration rate or requirement for hemodialysis. Eosinophilia is defined as an eosinophil count exceeding 500/μL. A total of 1022 patients were enrolled in the current study, and eosinophil counts (/μL) in the first through fourth eosinophil count quartiles were blood pressure, and total white blood cell count. Similarly, after adjustment for the same variables, eosinophilia was associated with severe renal dysfunction with an odds ratio of 2.60 (95 % confidence interval, 1.08-6.26, P count was positively associated with higher CKD stages among cardiology patients, some fraction of which might be related to subclinical cholesterol embolization.

    Blood eosinophilia (≥0.5 × 10(9) /l) may be an early sign of hematological malignancy. We investigated associations between levels of blood eosinophils and risks of hematological malignancies and mortality in order to provide clinically derived cut-offs for referral to specialist hematology care. From the Copenhagen Primary Care Differential Count (CopDiff) Database, we identified 356,196 individuals with at least one differential cell count encompassing the eosinophil count during 2000-2007 and matched these laboratory data with Danish nationwide health registers. We used multivariable logistic regression to calculate odds ratios (ORs) for the 4-year incidences of hematological malignancies and mortality between the eosinophil counts and a reference count of 0.16 × 10(9) /l which was the median eosinophil count in our data. Risks of hematological malignancies and mortality increased above the median eosinophil count. At the 99th percentile, corresponding to an eosinophil count of 0.75 × 10(9) /l, risks of hematological malignancies were increased more than twofold with OR (95% C.I.) of 2.39 (1.91-2.99). Interestingly, risks reached a plateau around an eosinophil count of 1.0 × 10(9) /l. Risks also increased when the eosinophil count approached zero. Here, counts associated relatively more with acute myeloid leukemia and myelodysplastic syndromes whereas counts above 0.16 × 10(9) /l associated more with myeloproliferative neoplasms. Eosinophil counts associate with hematological malignancies and mortality even below the definition of eosinophilia. The observed plateau of risks around 1.0 × 10(9) /l is important for physicians encountering patients with eosinophilia since even mild-to-moderate eosinophilia according to traditional definitions confers maximally increased risks of subsequent/subclinical hematological malignancy.

    BACKGROUND: Blood eosinophil counts might predict response to inhaled corticosteroids (ICS) in patients with chronic obstructive pulmonary disease (COPD) and a history of exacerbations. We used data from the WISDOM trial to assess whether patients with COPD with higher blood eosinophil counts would...... to receive either continued or reduced ICS over 12 weeks. We did a post-hoc analysis after complete ICS withdrawal (months 3-12) to compare rate of exacerbations and time to exacerbation outcomes on the basis of blood eosinophil subgroups of increasing cutoff levels.

    Full Text Available Allergic respiratory disorders are fairly common visiting cases in pediatrics outpatient department (OPD. With an appropriate history and detailed examination, diagnosis may not be problematic. Routine investigation may not contribute much to the final diagnosis but may help in ruling out other possibilities. This study was done to evaluate sensitivity and specificity of blood or nasal eosinophilia in subjects suffering from allergic respiratory disorders and also to assess the feasibility of nasal cytogram which is a simple, economical and reliable investigation in allergic respiratory disorders. This is a prospective clinical correlation study of patients attending outpatient department. 100 subjects aged between 2-18 years of either sex were selected for the estimation of eosinophil count in nasal and peripheral smear in allergic respiratory disorders. All allergic respiratory cases based on eosinophillia. The nasal and blood eosinophilia were compared with each other and clinical findings of allergic rhinitis with or without asthma were studied. In this study peak age incidence was seen between 11-18 years and it was more common in males. Rhinorrhoea, pale mucosa and nasal obstruction were common findings in allergic rhinitis with bronchial asthma. Nasal eosinophilia was seen in 52.4% and 64.9% of cases of allergic rhinitis and allergic rhinitis with asthma respectively. Blood eosinophilia was seen in 54% and 56.8% of cases of allergic rhinitis with asthma respectively. Nasal cytogram which is a simple, economical and non- invasive procedure can be used as an alternative to invasive peripheral smear eosinophilia as both are equally efficacious in diagnosing allergic respiratory diseases.

    IL-33 is a tissue-derived cytokine that induces and amplifies eosinophilic inflammation and has emerged as a promising new drug target for asthma and allergic disease. Common variants at IL33 and IL1RL1, encoding the IL-33 receptor ST2, associate with eosinophil counts and asthma. Through whole-genome sequencing and imputation into the Icelandic population, we found a rare variant in IL33 (NM_001199640:exon7:c.487-1G>C (rs146597587-C), allele frequency = 0.65%) that disrupts a canonical splice acceptor site before the last coding exon. It is also found at low frequency in European populations. rs146597587-C associates with lower eosinophil counts (β = -0.21 SD, P = 2.5×10–16, N = 103,104), and reduced risk of asthma in Europeans (OR = 0.47; 95%CI: 0.32, 0.70, P = 1.8×10–4, N cases = 6,465, N controls = 302,977). Heterozygotes have about 40% lower total IL33 mRNA expression than non-carriers and allele-specific analysis based on RNA sequencing and phased genotypes shows that only 20% of the total expression is from the mutated chromosome. In half of those transcripts the mutation causes retention of the last intron, predicted to result in a premature stop codon that leads to truncation of 66 amino acids. The truncated IL-33 has normal intracellular localization but neither binds IL-33R/ST2 nor activates ST2-expressing cells. Together these data demonstrate that rs146597587-C is a loss of function mutation and support the hypothesis that IL-33 haploinsufficiency protects against asthma. PMID:28273074

    Full Text Available BACKGROUND: Although a number of epidemiological studies, showing incidence and prevalence of atopic dermatitis, were available, scant attention has been paid to the correlation between the parameters of the disease like severity, absolute eosinophil count and IgE level, which has been known to be associated inconsistently. Hence this study was undertaken. METHODS: A total of 102 patients of atopic dermatitis, both children and adults, and 107 age matched controls were studied at the Pediatric Dermatology clinic, Institute of Child Health and department of Dermatology, AMRI-Apollo hospitals, Kolkata. RESULTS: The average age of onset of atopic dermatitis was observed to be 4.55 years. Both the average absolute eosinophil count and IgE levels in patients of atopic dermatitis were significantly higher than that of the controls. Each of these parameters showed significant correlation with severity of the disease and showed a nonhomogeneous distribution reflected by significant association with personal history of bronchial asthma and family history of atopy, when both parents were atopic. CONCLUSIONS: Our study shows that clinical activity of the disease as recorded by the "SCORAD" index can be used as an indicator of the hematological abnormalities as well as to some extent as a prognostic indicator. Family history of atopy correlates with the hematological abnormalities only if both parents are involved and bronchial asthma is the only associated atopic condition which correlates with the parameters of the disease .

    The circulating blood volume accounts for 8% of the body weight, of which 45% comprises cellular components (blood cells) and 55% liquid components. We can measure the number and morphological features of blood cells (leukocytes, red blood cells, platelets), or count the amount of hemoglobin in a complete blood count: (CBC). Blood counts are often used to detect inflammatory diseases such as infection, anemia, a bleeding tendency, and abnormal cell screening of blood disease. This count is widely used as a basic data item of health examination. In recent years, clinical tests before consultation have become common among outpatient clinics, and the influence of laboratory values on consultation has grown. CBC, which is intended to count the number of raw cells and to check morphological features, is easily influenced by the environment, techniques, etc., during specimen collection procedures and transportation. Therefore, special attention is necessary to read laboratory data. Providing correct test values that accurately reflect a patient's condition from the laboratory to clinical side is crucial. Inappropriate medical treatment caused by erroneous values resulting from altered specimens should be avoided. In order to provide correct test values, the daily management of devices is a matter of course, and comprehending data variables and positively providing information to the clinical side are important. In this chapter, concerning sampling collection, blood collection tubes, dealing with specimens, transportation, and storage, I will discuss their effects on CBC, along with management or handling methods.

    Fibronectin, which is present at relatively low levels in healthy central nervous systems (CNS), shows increased levels in meningitis. In this study, fibronectin processing was correlated with the increased permeability of the blood-cerebrospinal fluid (CSF) barrier as well as with the formation of eosinophil infiltrates in angiostrongyliasis meningitis. The immunohistochemistry results show matrix metalloproteinase-9 (MMP-9) is localized in the choroid plexus epithelium. Coimmunoprecipitation demonstrated fibronectin strongly binds MMP-9. Furthermore, treatment with the MMP-9 inhibitor GM6001 significantly inhibited fibronectin processing, reduced the blood-CSF barrier permeability, and decreased the eosinophil counts. The decreased fibronectin processing in CSF implies decreased cellular invasion of the subarachnoid space across the blood-CSF barrier. Therefore, increased fibronectin processing may be associated with barrier disruption and participate in the extravasation and migration of eosinophils into the CNS during experimental parasitic infection.

    Angiostrongylus cantonensis (A. cantonensis) is the most common cause of parasitic eosinophilic meningitis worldwide. By using an animal model of BALB/c mice infected with A. cantonensis, previous studies indicated that the anthelmintic drug, albendazole, could kill A. cantonensis larvae and prevent further infection. However, the dead larvae will induce severe immune responses targeting at brain tissues. To alleviate the detrimental effects caused by the dead larvae, we administered curcumin, a traditional anti-inflammatory agent, as a complementary treatment in addition to albendazole therapy, to determine whether curcumin could be beneficial for treatment. The results showed that although curcumin treatment alone did not reduce worm number, combined treatment by albendazole and curcumin helped to reduce eosinophil count in the cerebrospinal fluid, better than using albendazole alone. This alleviating effect did not affect albendazole treatment alone, since histological analysis showed similar worm eradication with or without addition of curcumin. Nevertheless, curcumin treatment alone and combined albendazole-curcumin treatment did not inhibit MMP-9 expression in the brain tissue. In conclusion, curcumin, when used as a complementary treatment to albendazole, could help to alleviate eosinophilic meningitis through suppression of eosinophil count in the cerebrospinal fluid.

    The design, fabrication, and tests of a prototype white blood cell counting system for use in the Skylab IMSS are presented. The counting system consists of a sample collection subsystem, sample dilution and fluid containment subsystem, and a cell counter. Preliminary test results show the sample collection and the dilution subsystems are functional and fulfill design goals. Results for the fluid containment subsystem show the handling bags cause counting errors due to: (1) adsorption of cells to the walls of the container, and (2) inadequate cleaning of the plastic bag material before fabrication. It was recommended that another bag material be selected.

    There is ongoing debate on the association between eosinophil count and diseases, as previous studies were inconsistent. We studied the relationship of eosinophil count with 22 complex metabolic, cardiac, and pulmonary traits and diseases. From the population-based LifeLines Cohort Study (N = 167,729), 13,301 individuals were included. We focused on relationship of eosinophil count with three classes of metabolic (7 traits, 2 diseases), cardiac (6 traits, 2 diseases), and pulmonary (2 traits, 2 diseases) outcomes. Regression analyses were applied in overall, women and men, while adjusted for age, sex, BMI and smoking. A p-value of <0.00076 was considered statistically significant. 58.2% of population were women (mean±SD 51.3±11.1 years old). In overall, one-SD higher of ln-eosinophil count was associated with a 0.04 (±SE ±0.002;p = 6.0×10−6) SD higher levels in ln-BMI, 0.06 (±0.007;p = 3.1×10−12) SD in ln-TG, 0.04 (±0.003;p = 7.0×10−6) SD in TC, 0.04 (±0.004;p = 6.3×10−7) SD in LDL, 0.04 (±0.006;p = 6.0×10−6) SD in HbA1c; and with a 0.05 (±0.004;p = 1.7×10−8) SD lower levels in HDL, 0.05 (±0.007;p = 3.4×10−23) SD in FEV1, and 0.09 (±0.001;p = 6.6×10−28) SD in FEV1/FVC. A higher ln-eosinophil count was associated with 1.18 (95%CI 1.09–1.28;p = 2.0×10−5) odds ratio of obesity, 1.29 (1.19–1.39;p = 1.1×10−10) of metabolic syndrome, 1.40 (1.25–1.56;p = 2.7×10−9) of COPD and 1.81 (1.61–2.03;p = 1.0×10−23) of asthma. Similar results were found in women. We found no association between ln-eosinophil count either with blood pressure indices in overall, women and men; or with BMI, LDL, HbA1c and obesity in men. In a large population based cohort, we confirmed eosinophil count as a potential factor implicated in metabolic and pulmonary outcomes. PMID:27978545

    2014-01-01

    Full Text Available Eosinophils are polyfunctional leukocytes detected in excess in blood and in the focus of granulomatous inflammation in pulmonary TB.The research objective was to evaluate the adhesive properties as well as cytokine-secretory and antibacterial activity of blood eosinophils in pulmonary TB.The research has been conducted on eosinophils isolated from peripheral blood of 43 patients with freshly identified progressive destructive TB with and without eosinophilia. Using flow cytometry and ELISA, expression of CD9 and CD18 adhesion molecules on blood eosinophils has been studied along with the phagocyte and cytokine-secretory functions and activity of eosinophil granulocyte peroxidase.As a result of the research it has been established that in TB patients with eosinophilia the number of CD18-expressing eosinophils rises, whereas the amount of CD9+ remains within norm. Activation of the phagocyte function of blood eosinophil granulocytes is associated with the decrease in eosinophil peroxidase activity, while the increase in IL-5 and TNFα secretory reactivity is connected with oppositely directed changes in  IL-2 basal secretion by eosinophils in vitro (a fall in infiltrative TB and a rise in disseminated TB.

    Gabriela E. S. Felix

    Full Text Available A complete blood count is very useful in clinical diagnoses when reference ranges are well established for the population. Complete blood counts and allele frequencies of Ancestry Informative Markers (AIMs were analyzed in Brazilians with the aim of characterizing the hematological values of an admixed population. Positive associations were observed between gender and neutrophils, monocytes, eosinophils, erythrocytes, hemoglobin, hematocrit, MCV, MCHC and platelet counts. No significant differences were found for age, alcohol consumption, educational status, ethnicity, smoking in respect to the complete blood count values. In general, men had higher red blood cell values, while women had higher values for white blood cells and platelets. The study of the population was highly heterogeneous with mean proportions (± SE of African, European and Amerindian ancestry being 49.0 ± 3.0%, 44.0 ± 9.0% and 7.0 ± 9.0%, respectively. Amerindian ancestry showed limited contribution to the makeup of the population, but estimated ancestral proportions were statistically significant (r = 0.9838; P<0.001. These hematologic values are similar to Afro-Americans, another admixed population.

    1996-01-01

    Full Text Available This study was undertaken to evaluate the role of IL-5 in eosinophil migration and in the maintenance of eosinophilia in a guinea-pig model of visceral larva migrans syndrome. The results show that the infection of animals with Toxocara canis induced an early increase in serum IL-5 levels that might be essential for eosinophil differentiation and proliferation and for the development of eosinophilia. When infected guinea-pigs were treated with mAb anti-IL-5 (TRFK-5 given at the same time or 1 or 3 days after infection, there was a high percentage of reduction of eosinophil counts 18 days after infection. However, when the mAb was administered during the peak of eosinophilia, there was high inhibition in blood, no inhibition in bronchoalveolar lavage fluid (BALF or peritoneum and an increase in eosinophil numbers in bone marrow. Thus, a basic level of IL-5 may be essential to drive eosinophils from bone marrow to blood and tissues, and for the maintenance of eosinophilia in infected animals. We may also conclude that when eosinophils have already migrated to the lungs, TRFK-5 has no power to inhibit eosinophilia, which is also under control of local lung cells producing IL-5. In this way, only one later TRFK-5 treatment may not be sufficient to modify the lung parenchyma microenvironment, since T. canis antigens had already stimulated some cell populations to produce IL-5.

    Small numbers of CD34+ primitive hematopoietic progenitors are found in normal human peripheral blood. These cells differentiate to myeloid or lymphoid lineage under the influence of growth factors. We investigated the effects of IL5 and other growth factors on the production of eosinophils from peripheral blood CD34+ cells. CD34+ cells were plated in agarose with different combinations of cytokines. At 14 days of growth a triple stain technique was used to identify eosinophil, monocyte and neutrophil colonies. IL5 alone did not support colony growth. In contrast GM-CSF and IL3 alone or together supported the generation of more than 50% eosinophil colonies. Addition of IL5 increased the fraction of eosinophil colonies to over 70%. Under the best conditions (IL3 + GM-CSF + IL5), the addition of interferon-a or LPS inhibited colony growth by 51% and 58%, respectively. Since IL5 alone did not support colony growth from CD34+ cells, we determined when IL5 responsive cells appeared in culture. Cells were grown initially with IL3 + GM-CSF, washed, and plated with IL5 alone. Only when progenitors were grown at least 3 days, could IL5 serve as the single growth factor supporting pure eosinophil colony growth (47 colonies/104 cells plated at day 3 and 134 colonies/104 cells at day 7). Growth of CD34+ in liquid culture for 28 days in the presence of IL3, GM-CSF and IL5 resulted in almost 250 fold increase in cell number, yielding a population of 83% maturing eosinophils. We used our culture system and the sensitive technique of RT-PCR to analyze the kinetics of production of mRNA transcripts encoding several eosinophil proteins. Freshly isolated CD34+ cells contained no eosinophil granule protein transcripts and barely detectable amounts of some oxidase protein transcripts. At day 3 of culture no cells recognizable by histochemical staining as eosinophils could be detected, but transcripts for all five eosinophil granule proteins were present. These transcripts increased

    Eosinophilic meningitis is defined by the presence of at least 10% eosinophils in the total cerebrospinal fluid (CSF) leukocyte count. Although there are several possible causes of eosinophils in the CSF, parasitic infection is the main cause. The three common parasites causing eosinophilic meningitis include Angiostrongylus cantonensis, Gnathostoma spinigerum, and Taenia solium. Even though these parasites are endemic in tropical countries, they are now spreading globally due to extensive traveling, and physicians worldwide should pay more attention to this condition. This chapter will review risk factors, clinical manifestations, and treatment of these three parasites.

    Severe or therapy-resistant asthma represents a major problem, and despite advanced treatment, many patients require oral corticosteroids (OCS). We aimed to determine if patients with severe asthma and elevated peripheral blood eosinophils (PBE) could have treatment with OCS adjusted using an algorithm that controlled PBE (asthma symptoms with an overall lower OCS dose.

    Objective To observe the influence of loratadine which was the second generation of H1 receptor antagonist on the expressions of interleukin 5 (IL- 5 )and eosinophil (EOS) count in bronchoalveolar lavage fluid(BALF) and peripheral blood in asthmatic guinea pigs,and explore the role of loratadine on airway high response of asthmatic guinea pigs. Methods Thirty -two guinea pigs were divided into normal control group, asthmatic group, low dose and high dose group of loratadine. After ovalbumin irritated, ovalbumin was inhaled to induce asthma breakout, meanwhile giving loratadine 2 mg · kg-1, 10 mg· kg- 1 in low dose group and high dose group. After the last inhaling ovalbumin,the airway pressure was detected by the animal respirator. Enzyme linked immunosorbent assay was used to measure the IL -5 in BALF and peri-pheral blood,meanwhile,EOS count was also detected. Results The serum IL -5 in normal control group,asthmatic group,low dose group and high dose group were(0.27 ±0.04) ng · L-1 ,(0.41 ±0.03) ng · L-1 ,(0. 38 ±0.02) ng · L-1 and (0.31 ±0.03) ng · L-1;IL-5 in BALF were (0. 10 ±0. 01 )ng · L-1 ,(0.38 ±0.04) ng · L-1 ,(0.33 ±0.05) ng · L-1 and (0.23 ±0.09) ng · L-1, respectively;the count of EOS in serum were(4.0 ±0. 6) × 108L-1, (54.6 ± 7.6) × 108L-1 , (44.5 ± 3.9) × l08L-1 and (29.0 ± 5.8) × 108L- 1 ;EOS in BALF in each group were(3.0 ±0. 5) × 108L-1 ,(33.7 ±3.9) × 108L-1 ,(27. 1 ±3.2) × l08L-1 and ( 18.6 ±3.3) × 108L-1. The differences between every 2 groups in each measurements were significant(Pa <0.05,0. 01 ). When inhaled histamine 10 mg · L-1 and 20 mg · L - 1, the differences between asthmatic group and low dose of loratadine group was not remarkable, but the difference between the rest 2 groups were prominent( Pa < 0. 05 ). Conclusions In asthmatic model, loratadine can ameliorate the airway high response, reverse the high IL-5 expressing condition in asthma,at the same time,the count of eosionphil is also

    The mechanism leading to selective production and accumulation of eosinophils in certain allergic skin diseases is unknown. Cyclophosphamide treatment (150 mg/kg) of BALB/c mice 48 h before sensitization with picryl chloride (PCl) resulted in striking blood and tissue eosinophilia, maximal at 13 days. Blood eosinophilia was not induced by the sensitization with oxazolone and 2,4-dinitrofluorobenzene. Challenge with 1 % PCl, but not croton oil caused preferential eosinophil accumulation into the dermis, which was associated with the enhanced expression of vascular cell adhesion molecule 1 (VCAM-1) on endothelial cells. Intravenous administration of anti-VCAM-1 monoclonal antibody abrogated eosinophil infiltration. In this murine model, we examined the role of several cytokines, including chemokines in inducing selective tissue eosinophilia in vivo. Local administration of antibodies against interleukin (IL)-1beta, IL-4, tumor necrosis factor (TNF)-alpha, and RANTES, but not against IL-5 before challenge inhibited hapten-induced eosinophil recruitment. Intradermal injection of recombinant (r)IL-1beta, rIL-4, rTNF-alpha, rRANTES, and rMIP-1alpha induced marked eosinophil accumulation. Nonetheless, intradermal rIL-5 was not a chemoattractant for eosinophils in vivo. Our findings suggest that IL-1beta, IL-4, TNF-alpha, and RANTES contribute to the selective accumulation of eosinophils in contact sensitivity reaction. Although circulating IL-5 can activate eosinophils and prolong their survival, locally secreted IL-5 is not crucial for inducing eosinophil recruitment into the skin.

    White blood cell count is an important indicator of each individual's health condition. An abnormal white blood cell count usually results from an infection, cancer, or other conditions that trigger systemic inflammation responses. White blood cell count also provides predictive information on the incidence of cardiovascular diseases and Type 2 diabetes. Therefore, monitoring white blood cell count on a regular basis can potentially help individuals to take preventive measures and improve healthcare outcomes. Currently, white blood cell count is primarily conducted in centralized laboratories, and it requires specialized equipment and dedicated personnel to perform the test and interpret the results. So far there has been no rapid test that allows white blood cell count in low-resource settings. In this study, we have demonstrated a vertical flow platform that quantifies white blood cells by trapping them in the paper. White blood cells were tagged with gold nanoparticles, and flowed through the paper via a small orifice. The white blood cell count was determined by measuring the colorimetric intensity of gold nanoparticles on the surface of white blood cells that were trapped in the paper mesh. Using this platform, we were able to quantify white blood cells in 15 μL of blood, and visually differentiate the abnormal count of white blood cells from the normal count. The proposed platform enabled rapid white blood cell count in low resource settings with a small sample volume requirement. Its low-cost, instrument-free operations would be attractive for point-of-care applications.

    Full Text Available Basophils are blood cells of low abundance associated with allergy, inflammation and parasite infections. To study the transcriptome of mature circulating basophils cells were purified from buffy coats by density gradient centrifugations and two-step magnetic cell sorting. However, after extensive analysis the cells were found to be transcriptionally inactive and almost completely lack functional mRNA. In order to obtain transcriptionally active immature basophils for analysis of their transcriptome, umbilical cord blood cells were therefore cultured in the presence of interleukin (IL-3 for 9 days and basophils were enriched by removing non-basophils using magnetic cell sorting. The majority of purified cells demonstrated typical metachromatic staining with Alcian blue dye (95% and expression of surface markers FcεRI and CD203c, indicating a pure population of cells with basophil-like phenotype. mRNA was extracted from these cells and used to construct a cDNA library with approximately 600 000 independent clones. This library served as tool to determine the mRNA frequencies for a number of hematopoietic marker proteins. It was shown that these cells express basophil/mast cell-specific transcripts, i.e. β-tryptase, serglycin and FcεRI α-chain, to a relatively low degree. In contrast, the library contained a high number of several eosinophil-associated transcripts such as: major basic protein (MBP, charcot leyden crystal (CLC, eosinophil cationic protein (ECP, eosinophil derived neurotoxin (EDN and eosinophil peroxidase (EPO. Out of these transcripts, MBP and EPO were the most frequently observed, representing 8% and 3.2% of the total mRNA pool, respectively. Moreover, in a proteome analysis of cultured basophils we identified MBP and EPO as the two most prominent protein bands, suggesting a good correlation between protein and mRNA analyses of these cells.

    IL-5 is a Th2 cytokine which activates eosinophils and is suggested to have an atheroprotective role. Genetic variants in the IL5 locus have been associated with increased risk of CAD and ischemic stroke. In this study we aimed to identify genetic variants associated with IL-5 concentrations and apply a Mendelian randomisation approach to assess IL-5 levels for causal effect on intima-media thickness in a European population at high risk of coronary artery disease. We analysed SNPs within robustly associated candidate loci for immune, inflammatory, metabolic and cardiovascular traits. We identified 2 genetic loci for IL-5 levels (chromosome 5, rs56183820, BETA=0.11, P=6.73E(-5) and chromosome 14, rs4902762, BETA=0.12, P=5.76E(-6)) and one for eosinophil count (rs72797327, BETA=-0.10, P=1.41E(-6)). Both chromosome 5 loci were in the vicinity of the IL5 gene, however the association with IL-5 levels failed to replicate in a meta-analysis of 2 independent cohorts (rs56183820, BETA=0.04, P=0.2763, I(2)=24, I(2)-P=0.2516). No significant associations were observed between SNPs associated with IL-5 levels or eosinophil count and IMT measures. Expression quantitative trait analyses indicate effects of the IL-5 and eosinophil-associated SNPs on RAD50 mRNA expression levels (rs12652920 (r2=0.93 with rs56183820) BETA=-0.10, P=8.64E(-6) and rs11739623 (r2=0.96 with rs72797327) BETA=-0.23, P=1.74E(-29), respectively). Our data do not support a role for IL-5 levels and eosinophil count in intima-media thickness, however SNPs associated with IL-5 and eosinophils might influence stability of the atherosclerotic plaque via modulation of RAD50 levels.

    Case records of 9 dogs and 5 cats with eosinophilic effusions were reviewed. The animals ranged from 11 months to 13 years old. Seven animals had pleural effusions, 5 had peritoneal effusions, and 2 had pleural and peritoneal effusions. Neoplasia was confirmed in 6 animals and suspected in 1. Eosinophilic pleural effusion was diagnosed 2 days after pneumothorax developed as a consequence of thoracic tube placement in a cat, and pneumothorax was diagnosed in another cat with eosinophilic peritoneal effusion. Other abnormalities seen in 1 or 2 animals associated with eosinophilic effusion were radiographic signs of interstitial or peribronchial pulmonary infiltrates, a history of allergic respiratory tract and skin disease, intestinal lymphangiectasia and lung lobe torsion, chylothorax, bite wounds causing intestinal perforation, and feline leukemia virus infection. Based only on the protein concentration of the effusion, 7 effusions were classified as transudates and 7 were classified as exudates. Five of the 14 animals had eosinophilia (> 1,200 eosinophils/microliters); 3 of these animals had neoplastic disease. Mean eosinophil count in blood samples was not significantly different between animals with neoplasia and those without. Eosinophil counts in blood samples were not linearly related to counts in effusions; however, in some animals the number of eosinophils in the effusion was much higher than the eosinophil count in blood, suggesting concentration of eosinophils in the effusion.

    Atherosclerosis is an inflammatory disease, and several inflammatory biomarkers, such as C-reactive protein, have been used to predict the risk of coronary heart disease. High white blood cell count is a strong and independent predictor of coronary risk in patients of both sexes, with and without coronary heart disease. A high number of white blood cells and their subtypes (for example, neutrophils, monocytes, lymphocytes, and eosinophils) are associated with the presence of coronary heart disease, peripheral arterial disease, and stroke. The coronary heart disease risk ratios associated with a high white blood cell count are comparable to those of other inflammatory markers, including C-reactive protein. In addition, other components of the complete blood count, such as hematocrit and the erythrocyte sedimentation rate, also are associated with coronary heart disease, and the combination of the complete blood count with the white blood cell count can improve our ability to predict coronary heart disease risk. These tests are inexpensive, widely available, and easy to order and interpret. They merit further research.

  5. Eosinophilic Pleural Effusion: A Rare Manifestation of Hypereosinophilic Syndrome

    2009-01-01

    Full Text Available Several causes of eosinophilic pleural effusions have been described with malignancy being the commonest cause. Hypereosinophilic syndrome (HES is a rare disease and very few cases have been reported of HES presenting as eosinophilic pleural effusion (EPE. We report a case of a 26-year-old male who presented with shortness of breath. He had bilateral pleural effusions, generalized lymphadenopathy, splenomegaly, and leukocytosis with marked peripheral blood eosinophilia. The pleural fluid was exudative, with 25%–30% eosinophilis, and absence of neoplastic cells. Hypereosinophilic syndrome was diagnosed after other causes of eosinophilia were excluded. He continued to be dyspneic with persistent accumulation of eosinophilic pleural fluid, even after his peripheral eosinophil count had normalized in response to treatment. This patient represents a very unusual presentation of HES with dyspnea and pleural effusions and demonstrates that treatment based on response of peripheral eosinophil counts, as is currently recommended, may not always be clinically adequate.

    This study presents the results of an aging stability study of complete blood count (CBC) and leukocyte differential parameters using the Abbott CELL-DYN Sapphire hematology analyzer. Stability studies showed no substantial change in CBC parameters up to 24-48 h at +23 +/- 2 degrees C (room temperature), except for optical platelet count (PLTo). For specimens aged over 24, the value of impedance platelet count yielded more reliable results than the routine PLTo. White blood cell (WBC) differential parameters, except eosinophils, were stable for up to 48 h at +23 +/- 2 degrees C. CBC parameters were stable for 72 h, except mean platelet volume, which slightly increased between 48 and 72 h, at +4 degrees C. WBC differentials were stable 48-72 h, with a slight decrease observed in absolute neutrophils and lymphocytes at +4 degrees C.

    A 14-year-old female domestic shorthair cat was presented to Tehran University Veterinary Teaching Hospital for a persistent fever, anorexia, intermittent vomiting, weight loss and weakness. The main clinical signs were pale mucous membranes, dehydration and splenomegaly. The complete blood count and serum biochemistry tests revealed non-regenerative anaemia, thrombocytopenia and increased alkaline phosphatase (ALP) activity. An enzyme-linked immunosorbent assay (ELISA) test for feline leukaemia virus was negative. Blood film and bone marrow examination revealed a large number of immature eosinophils with variable sizes and numbers of faintly azurophilic granules. Cytochemical staining of blood film demonstrated 70% positive cells for ALP activity. Four percent CD34 positive cells were detected by flow cytometry. As eosinophilic leukaemia is difficult to identify by light microscopy, well-defined diagnostic criteria and the use of flow cytometry and cytochemical staining can improve the ability to correctly diagnose this type of leukaemia in cats.

    Asthma is a heterogeneous disease that can be classified into different clinical endotypes, depending on the type of airway inflammation, clinical severity, and response to treatment. This article focuses on the eosinophilic endotype of asthma, which is defined by the central role that eosinophils play in the pathophysiology of the condition. It is characterized by elevated sputum and/or blood eosinophils on at least 2 occasions and by a significant response to treatments that suppress eosinophilia. Histopathologic demonstration of eosinophils in the airways provides the most direct diagnosis of eosinophilic asthma; but it is invasive, thus, impractical in clinical practice.

    Recent studies suggest that many fatal heroin overdoses are caused by anaphylactoid reaction. In the present study we measured tryptase and eosinophil cationic protein in post-mortem blood of 48 deaths after heroin injection. We also investigated the presence and pulmonary distribution of mast-cells using specific immunohistochemical antibody for tryptase and morphometric evaluation in those cases of heroin-related deaths. The data were compared with 44 subjects who died following head trauma and to 32 cases of fatal anaphylactic shock. In the heroin-related death cases, the measurements of serum tryptase levels and eosinophil cationic protein dosages resulted in particularly elevated concentrations compared with the trauma cases. Nevertheless, the data that our study supplies by immunohistochemical techniques indicate that when mast-cells count in the lung was determined, no definite pattern was obtained between fatal heroin overdose cases and the control groups. Furthermore, the wide range of morphine concentrations found in post-mortem blood samples suggest that the term 'overdose' is relative and does not sufficiently characterize death associated with heroin addiction. Our study confirms that elevated concentrations of serum tryptase are associated with many heroin-related deaths. At this moment to attribute the cause of these deaths to 'heroin overdose' ignores the likely causal contribution of other possible systemic reactions to the mechanism of death.

    Background The airway inflammation could be assessed by some noninvasive approaches.To investigate the value of eosinophil counts in induced sputum and fractional concentration of exhaled nitric oxide (FENO) for the regimen adjustment in patients with asthma,the correlation was analyzed between the two parameters and lung function parameter (forced expiratory volume in one second (FEV1)).Methods Sixty-five outpatients with mild to moderate non-exacerbation asthma from Beijing Chao-Yang Hospital were enrolled as treatment group.Combined medications of inhaled corticosteroids plus long-acting beta-2 agonist were administered for one year.Lung function parameters,eosinophil counts in induced sputum,concentration of exhaled nitric oxide and the Asthma Control Test scores were recorded,at regular intervals in the follow-up period.Twenty-one healthy volunteers were enrolled as control group and underwent examination of eosinophil counts in induced sputum,lung function and concentration of exhaled nitric oxide.Results Sixty-three subjects from treatment group completed follow-up period for one year or longer.Mean FEV1 value of the 63 subjects was (2.75±0.54) L at baseline,(2.97±0.56) L and (3.07±0.52) L at month 3 and month 6,respectively,and maintained as (3.14±0.51) L in the following six months.Mean FENO decreased from (61±25) parts per billion (ppb) at baseline to (32±19) ppb at month 3 (P <0.05),and continued to decrease to (22±12) ppb at month 6,the difference being significant when compared to both baseline and control group ((13±8) ppb).Mean eosinophil counts decreased to (0.032±0.011) ×106/ml at month 3,which was significantly different from baseline ((0.093±0.023)×106/ml) and the control group ((0.005±0.003) ×106/ml (both P <0.05).The eosinophil counts in induced sputum correlated positively with concentration of FENO in the first six months (all P <0.05).The concentration of FENO had a significant negative correlation with FEV1 value (all P

    While cigarette smoking is a well-recognized cause of elevated white blood cell (WBC) count, studies on longitudinal effect of smoking cessation on WBC count are limited. We attempted to determine causal relationships between smoking and elevated WBC count by retrospective cross-sectional study consisting of 37,972 healthy Japanese adults who had a health check-up between April 1, 2008 and March 31, 2009 and longitudinal study involving 1730 current smokers who had more than four consecutive annual health check-ups between April 1, 2007 and March 31, 2012. In the cross-sectional study, younger age, male gender, increased body mass index, no alcohol habit, current smoking, and elevated C-reactive protein level were associated with elevated WBC count. Among these factors, current smoking had the most significant association with elevated WBC count. In subgroup analyses by WBC differentials, smoking was significantly associated with elevated counts of neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Ex-smoking was not associated with elevated WBC count. In the longitudinal study, both WBC and neutrophil counts decreased significantly in one year after smoking cessation and remained down-regulated for longer than next two years. There was no significant change in either WBC or neutrophil count in those who continued smoking. These findings clearly demonstrated that current smoking is strongly associated with elevated WBC count and smoking cessation leads to recovery of WBC count in one year, which is maintained for longer than subsequent two years. Thus, current smoking is a significant and reversible cause of elevated WBC count in healthy adults.

    Full Text Available Complete blood count (CBC reference intervals are important to diagnose diseases, screen blood donors, and assess overall health. However, current reference intervals established by older instruments and technologies and those from American and European populations are not suitable for Chinese samples due to ethnic, dietary, and lifestyle differences. The aim of this multicenter collaborative study was to establish CBC reference intervals for healthy Han Chinese adults.A total of 4,642 healthy individuals (2,136 males and 2,506 females were recruited from six clinical centers in China (Shenyang, Beijing, Shanghai, Guangzhou, Chengdu, and Xi'an. Blood samples collected in K2EDTA anticoagulant tubes were analyzed. Analysis of variance was performed to determine differences in consensus intervals according to the use of data from the combined sample and selected samples.Median and mean platelet counts from the Chengdu center were significantly lower than those from other centers. Red blood cell count (RBC, hemoglobin (HGB, and hematocrit (HCT values were higher in males than in females at all ages. Other CBC parameters showed no significant instrument-, region-, age-, or sex-dependent difference. Thalassemia carriers were found to affect the lower or upper limit of different RBC profiles.We were able to establish consensus intervals for CBC parameters in healthy Han Chinese adults. RBC, HGB, and HCT intervals were established for each sex. The reference interval for platelets for the Chengdu center should be established independently.

    Full Text Available A 45 year-old male presented with cough and expectoration for 8 months, short-ness of breath and wheeze for 3 months, and fever for 1 month. He remained symptomatic despite repeated courses of antibiotics with partial relief on oral and inhaled bronchodilators. Despite several sputum examinations being negative for acid fast bacilli (AFB, he was put on anti-tubercular drugs (ATD because of bi-lateral infiltrates on his chest radiographs. A mildly raised blood eosinophil count, eosinophilia in broncho-alveolar lavage (BAL fluid and eosinophilic infiltration on CT guided FNAC from his lung lesion raised the suspicion and the dramatic clinico-radiological improvement with oral corticosteroids clinched the diagnosis of CEP.

    Body mass index (BMI), the prevalent indicator of obesity, is not easily grasped by patients nor physicians. Waist circumference (WC) is correlated to obesity, is better understood and has a stronger relationship to the metabolic syndrome. We compiled WC, complete blood count (CBC) parameters as well as other pertinent data of 6766 25-55-year-old US volunteers sampled in the US National Health and Nutrition Examination Survey, in the years 2005-2010. To determine reference intervals of typical US patients visiting their clinician, we used minimal exclusion criteria. We compiled hemoglobin, red blood cell count, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration, mean cell hemoglobin (MCH), red cell distribution width (RDW), platelet count, mean platelet volume, and counts of white blood cells (WBC), neutrophils, lymphocytes, monocytes, eosinophils, and basophils. In addition, we also compiled serum C reactive protein and serum iron. The three major US races were studied and reference interval diagrams were constructed for each CBC parameter plotted against WC. WBC count, RDW, lymphocyte, neutrophil, and red blood cell count increase with WC. Conversely, serum iron and MCH and MCV decrease. These relationships may be related to insulin resistance and chronic activation of the immune system and the resulting low-grade inflammatory state. WC is a strong predictor for many CBC parameters, suggesting that WC should be taken into account when evaluating blood count results. Clinicians who take care of obese patients should be aware of altered hematology and investigate and treat accordingly.

    Small numbers of CD34+ primitive hematopoietic progenitors are found in normal human peripheral blood. These cells differentiate to myeloid or lymphoid lineage under the influence of different growth factors. We investigated the effects of IL5 and other growth factors on the production of eosinophils from peripheral blood CD34+ cells. CD34+ cells were enriched from normal donors by apheresis and positive selection using an affinity column and plated in agarose with different combinations of cytokines. At 14 days of growth a triple stain technique was used to identify eosinophil, monocyte, and neutrophil colonies. IL5 alone did not support colony growth from CD34+ cells. In contrast, GM-CSF and IL3 alone or together without added IL5 supported the generation of more than 50% pure eosinophil colonies. Addition of IL5 did not change the total number of colonies, but increased the fraction of pure eosinophil colonies to over 70%. Addition of G-CSF reduced the percentage of eosinophil colonies and increased the percentage of neutrophil colonies. Under the best conditions for eosinophil colony growth (IL3+GM-CSF+IL5), the addition of interferon-alpha or bacterial lipopolysaccharide inhibited colony growth by 51 and 58%, respectively. Addition of interferon-gamma, tumor necrosis factor-alpha, or dexamethasone had no effect on eosinophil colonies. Since IL5 alone did not support colony growth from CD34+ cells, we determined when IL5-responsive cells appeared in culture. Cells were grown initially with IL3 + GM-CSF in suspension, washed, and plated in agarose with IL5 alone. Only when progenitors were grown at least 3 days could IL5 serve as the single growth factor supporting pure eosinophil colony growth (47 colonies/10(4) cells plated at Day 3 and 134 colonies/10(4) cells at Day 7). We used neutralizing anti-IL5 antibodies to demonstrate that this late acting IL5 growth effect was specific, and that differentiation of eosinophils in the presence of IL3 + GM-CSF was IL5

    A selective recruitment of eosinophils to sites of inflammation is claimed to be controlled by regulation of cytokines, chemokines and adhesion molecules. In animal models, eotaxin has been suggested to be a potent chemokine since it in cooperation with interleukin-5 induce selective chemotaxis and infiltration of eosinophils to lung tissue after an allergen provocation. We have investigated the in vitro effect of eotaxin on human peripheral blood eosinophils with respect to CD11b/CD18 expression and adhesion properties to the matrix protein fibronectin. We did not find any effect of eotaxin per se on CD11b/CD18 expression, neither on eosinophils from healthy subjects nor from patients with asymptomatic pollen related asthma. However, eotaxin significantly upregulated the quantitative level of CD11b/CD18 and increased the adhesion to fibronectin in eosinophils from healthy subjects preincubated in vitro with interleukin-5, but not in eosinophils preincubated with fMLP. Moreover, eosinophils harvested 24 hours after an in vivo allergen inhalation provocation in asthmatics, upregulated CD11b/CD18 after in vitro incubation with eotaxin alone.

    Absolute neutrophil count (ANC) is used clinically to monitor physiological dysfunctions such as myelosuppression or infection. In the research laboratory, ANC is a valuable measure to monitor the evolution of a wide range of disease states in disease models. Flow cytometry (FCM) is a fast, widely used approach to confidently identify thousands of cells within minutes. FCM can be optimised for absolute counting using spiked-in beads or by measuring the sample volume analysed. Here we combine the 1A8 antibody, specific for the mouse granulocyte protein Ly6G, with flow cytometric counting in straightforward FCM assays for mouse ANC, easily implementable in the research laboratory. Volumetric and Trucount™ bead assays were optimized for mouse neutrophils, and ANC values obtained with these protocols were compared to ANC measured by a dual-platform assay using the Orphee Mythic 18 veterinary haematology analyser. The single platform assays were more precise with decreased intra-assay variability compared with ANC obtained using the dual protocol. Defining ANC based on Ly6G expression produces a 15% higher estimate than the dual protocol. Allowing for this difference in ANC definition, the flow cytometry counting assays using Ly6G can be used reliably in the research laboratory to quantify mouse ANC from a small volume of blood. We demonstrate the utility of the volumetric protocol in a time-course study of chemotherapy induced neutropenia using four drug regimens.

    Alterations of mitochondrial DNA copy number (mtDNAcn) in the blood (mitochondrial to nuclear DNA ratio) appear associated with several systemic diseases, including primary mitochondrial disorders, carcinogenesis, and hematologic diseases. Measuring mtDNAcn in DNA extracted from whole blood (WB) instead of from peripheral blood mononuclear cells or buffy coat may yield different results due to mitochondrial DNA present in platelets. The aim of this work is to quantify the contribution of platelets to mtDNAcn in whole blood [mtDNAcn(WB)] and to propose a correction formula to estimate leukocytes' mtDNAcn [mtDNAcn(L)] from mtDNAcn(WB). Blood samples from 10 healthy adults were combined with platelet-enriched plasma and saline solution to produce artificial blood preparations. Aliquots of each sample were combined with five different platelet concentrations. In 46 of these blood preparations, mtDNAcn was measured by qPCR. MtDNAcn(WB) increased 1.07 (95%CI 0.86, 1.29; p<0.001) per 1000 platelets present in the preparation. We proved that leukocyte count should also be taken into account as mtDNAcn(WB) was inversely associated with leukocyte count; it increased 1.10 (95%CI 0.95, 1.25, p<0.001) per unit increase of the ratio between platelet and leukocyte counts. If hematological measurements are available, subtracting 1.10 the platelets/leukocyte ratio from mtDNAcn(WB) may serve as an estimation for mtDNAcn(L). Both platelet and leukocyte counts in the sample are important sources of variation if comparing mtDNAcn among groups of patients when mtDNAcn is measured in DNA extracted from whole blood. Not taking the platelet/leukocyte ratio into account in whole blood measurements, may lead to overestimation and misclassification if interpreted as leukocytes' mtDNAcn. PMID:27736919

    EDTA-dependent pseudothrombocytopenia (EDTA-PTCP) is a phenomenon that occurs in vitro when EDTA reacts with harvested blood. EDTA-dependent pseudothrombocytopenia usually does not indicate thrombocytopenia in vivo. Here, we report the first case of EDTA-PTCP complicated by eosinophilic pneumonia. A 70-year-old man with rectal cancer was admitted to the hospital for a liver abscess and rectal cancer. At the time of admission, his platelet count was 20,000/μL, but a peripheral blood smear showed platelet aggregation and the platelet count for a kanamycin-added EDTA blood sample was 180,000/μL. The patient's respiratory status worsened after treatment for the liver abscess and rectal cancer. The patient's bronchoalveolar lavage contained 45% eosinophils, and a diagnosis of acute eosinophilic pneumonia was made. In recent studies, the occurrence of eosinophilic disease has been shown in idiopathic thrombocytopenic purpura. EDTA-dependent pseudothrombocytopenia is an in vitro phenomenon, although platelet activation that results in eosinophil invasion may occur in severe cases.

    A 26-year-old man presented with a history of intermittent erythematous plaques on his hands and legs. A peripheral blood eosinophilia was noted. Histopathologic examination showed numerous eosinophils and characteristic flame figures. The clinical presentation and histopathologic alterations are consistent with the diagnosis of Wells' syndrome, which is also known as eosinophilic cellulitis. Wells' syndrome is a rare condition of unclear etiology. We discuss its diagnosis and possible association with other conditions that manifest peripheral eosinophilia.

    Current laboratory standards from Clinical Laboratory Standards Institute (CLSI) and manufacturer's (Becton Dickinson) data indicate that under-filling K(2)EDTA blood collection tubes can result in erroneous hematology values. To accommodate under-filled tubes and reduce collection volumes while optimizing our automation, we explored the acceptable limit of under-filled tubes for hematology values. We collected 8.0 ml of blood from 30 normal adult volunteers. Each donation was aliquoted in the following volumes: 4.0, 2.0, 1.0, 0.5 ml x 2. These samples were analyzed within 1 h of blood collection on Sysmex XE-2100 (Sysmex America Inc., Mundelein, IL, USA) for complete blood count, reticulocyte, and white blood cell differentials. Results of the under-filled tubes were compared to those of the standard volume. The Deming regression analysis show excellent correlation for all parameters between each under-filled blood collection volume compared to a standard 4 ml volume. The Bland and Altman analysis shows good agreement between both 1.0 and 2.0 ml compared to a 4.0 ml volume. The 0.5 ml compared to a 4.0 ml volume, however, shows increased variation on many parameters. In addition all three collection volumes show negative bias compared to the standard volume for platelet count, but the difference is considered insignificant with a percent difference of 5.5%, 3.2%, and 1.5% for 0.5, 1.0, and 2.0 ml collection volume respectively. Finally for 0.5 ml collection volume we noticed a low level of false positive flagging rate for white blood cell. Acceptable complete blood count values of under-filled powdered K(2)EDTA tubes can be obtained with as little as 1.0 ml of blood.

    Complete blood cell count (CBC) data from heparinized blood gas (H-Gas) samples were verified with primary focus on the platelet count (PLT). When a part of H-Gas sample was taken to a separation tube from the blood collection syringe and CBC of the sample in the separation tube was repeatedly measured (Procedure 1), the PLT from 5 samples relative to that obtained immediately after the separation was gradually reduced to 72.6-94.2% during serial measurements (every 5 minutes, up to 30 minutes). The change in the scattergram pattern suggested that this PLT decrease was due to the formation of platelet clumps. The white blood cell count (WBC), red blood cell count (RBC), hemoglobin (Hb) and hematocrit (Ht) values did not significantly change during the repeated measurements. On the other hand, PLT was significantly improved to 96.8-99.8% when the H-Gas sample was kept in the blood collection syringe so as to minimizing the exposure to the air, and the sample for the measurement from H-Gas was taken every time to separation tube from the syringe, followed by CBC measurement without delay (Procedure 2). In addition, while there were significant variations (CV: 11.8-18.2%) in PLT reproducibility among H-Gas samples by Procedure 1, measurements utilizing the Procedure 2 resulted in much smaller variations (CV: 2.2-3.7%). Thus the CBC data obtained from H-Gas samples were equivalent to those from EDTA samples when the Procedure 2 was applied. These data suggest that H-Gas samples can be used for the accurate CBC measurement, including PLT, by applying the Procedure 2.

    Eosinophilic gastroenteritis is a rare disease of unknown etiology. It is characterized by eosinophilic infiltration of the bowel wall to a variable depth and symptoms associated with gastrointestinal tract. Recently, the authors experienced a case of eosinophilic gastroenteritis presenting as small bowel obstruction. A 51-year old woman was admitted to our hospital complaining of abdominal pain and vomiting. Physical examination revealed a distended abdomen with diffuse tenderness. Complete blood count showed mild leukocytosis without eosinophilia. Computed tomography confirmed a dilatation of the small intestine with ascites. An emergency laparotomy was performed for a diagnosis of peritonitis due to intestinal obstruction. Segmental resection of the ileum and end to end anastomosis were performed. Histologically, there was a dense infiltration of eosinophils throughout the entire thickness of ileal wall and eosinophilic enteritis was diagnosed. The patient recovered well, and was free from gastrointestinal symptoms at the time when we reported her disease.

    Full Text Available The present study was undertaken to see the effect of mastitic pathogens on the blood and milk counts of Murrah buffaloes. Milk and blood samples were collected from 9 mastitic Murrah buffaloes. The total leucocyte Counts (TLC and Differential leucocyte counts (DLC in blood were within normal range and there was a non-significant change in blood counts irrespective of different mastitic pathogens. Normal milk quarter samples had significantly (P<0.01 less Somatic cell counts (SCC. Lymphocytes were significantly higher in normal milk samples, whereas infected samples had a significant increase (P<0.01 in milk neutrophils. S. aureus infected buffaloes had maximum milk SCC, followed by E. coli and S. agalactiae. Influx of neutrophils in the buffalo mammary gland was maximum for S. agalactiae, followed by E.cli and S. aureus. The study indicated that level of mastitis had no affect on blood counts but it influenced the milk SCC of normal quarters.

    Eosinophilic colitis (EC) is a rare form of primary eosinophilic gastrointestinal disease with a bimodal peak of prevalence in neonates and young adults. EC remains a little understood condition in contrast to the increasingly recognized eosinophilic esophagitis. Clinical presentation of EC is highly variable according to mucosal, transmural, or serosal predominance of inflammation. EC has a broad differential diagnosis because colon tissue eosinophilia often occurs in parasitic infection, drug-induced allergic reactions,inflammatory bowel disease, and various connective tissue disorders, which require thorough searching for secondary causes that may be specifically treated with antibiotics or dietary and drug elimination.Like eosinophilic gastrointestinal disease involving other segments of the gastrointestinal tract, EC responds very well to steroids that may be spared by using antihistamines, leukotriene inhibitors and biologics.

    2016-01-01

    Eosinophilic fasciitis is a rare sclerodermiform syndrome of unknown etiology. It is characterized by the thickening of the muscular fascia and subcutaneous tissue, with a variable infiltration of eosinophils. Peripheral eosinophilia, poly or monoclonal hypergammaglobulinemia and increased erythrocyte sedimentation rate can be seen. Clinical features begin acutely, with local edema and a painful and symmetrical stiffening of the limbs, progressing rapidly to fibrosis, which can limit joint movements. Some cases have a history of strenuous physical exercise or trauma. The diagnosis is confirmed by a deep skin biopsy. Glucocorticoids in high doses is the treatment of choice. We report a typical eosinophilic fasciitis case with peripheral eosinophilia and dramatic response to pulse therapy with methylprednisolone.

    2009-01-01

    Eosinophilic esophagitis is increasingly recognized in adults. The diagnosis is based on the presence of both typical symptoms and pathologic findings on esophageal biopsy. Patients usually present with dysphagia, food impaction and/or reflux-like symptoms, and biopsy of the esophagus shows more than 15 eosinophils per high-power field. In addition,it is essential to exclude the presence of known causes of tissue eosinophilia such as gastroesophageal reflux disease, infections, malignancy, collagen vascular diseases, hypersensitivity, and inflammatory bowel disease. There are no standardized protocols for the therapy of eosinophilic esophagitis. A variety of therapeutic approaches including acid suppression, dietary modi f icat ions, topical cor t icosteroids and endoscopic dilation can be used alone or in combination.

    To investigate the effects of IL-5 on the expression of TGF-β1 in eosinophils in vitro, eosinophils were incubated in the presence of the same concentrations of IL-4, IL-5 and IFNγ, different concentrations of IL-5 in vitro and changes of eosinophil viability were assessed by trypan blue exclusion. Non-cytokine was employed as a negative control. 16 h after the cultivation, supernatants and cells were assayed by using TGF-β1 specific ELISA and RT-PCR. The mRNA expression and protein expresssion of TGF-β1 in eosinophils stimulated with different cytokines was observed.The expression of TGF-β1 protein in eosinophils was increased significantly by IL-4 (433.67±9.86vs 228.9±2.87) and IL-5 (403. 72±7.60 vs 228.9±2.87, P<0.05), while decreased by IFNγ (178.47±2.60 vs 228.9±2.87). At the same time, the results demonstrated that the basal level of TGF expression was enhanced by IL5 in all samples (P<0.05). The expression of TGF β1 mRNA was 1.42, 1. 70, 1. 76-folds higher than that of the non-stimulated controls. It is concluded that IL-5 can up-regulate the expression of TGF-β1 in eosinophils in vitro, which might have effect in eosinophil-associated chronic rejection.

    This retrospective cross-sectional study examined if the white cell count (WCC) is increased in women with polycystic ovary syndrome (PCOS) and if so, is it due to PCOS or to the associated obesity? Body mass index (BMI) was calculated and body composition was measured using bioelectrical impedance analysis. Of the 113 women studied, 36 had PCOS and 77 did not. The mean WCC was higher in the PCOS group compared with the non-PCOS group (8.9 x 10(9)\\/l vs 7.4 x 10(9)\\/l p = 0.002). This increase was due to a higher neutrophil count (5.6 x 10(9)\\/l vs 4.3 x 10(9)\\/l; p = 0.003). There was a leucocytosis (WCC >11 x 10(9)\\/l) present in 19% of the PCOS group compared with 1% in the non-PCOS group (p < 0.001). The neutrophil count was abnormally high (>7.7 x 10(9)\\/l) in 14% of the PCOS group compared with 4% in the non-PCOS group (p < 0.001). On regression analysis, however, the only independent variable which explained both the increased WCC and the increased neutrophil count was PCOS. We found that PCOS is associated with an increased WCC due to increased neutrophils, which supports the evidence that PCOS is associated with low-grade inflammation. The increase appears to be due to the underlying PCOS, and not to the increased adiposity associated with PCOS.

    We demonstrate that the concentration of a red blood cell solution under physiological conditions can be determined by electrochemical voltammetry. The magnitude of the oxygen reduction currents produced at an edge-plane pyrolytic graphite electrode was diagnosed analytically at concentrations suitable for a point-of-care test device. The currents could be further enhanced when the solution of red blood cells was exposed to hydrogen peroxide. We show that the enhanced signal can be used to detect red blood cells at a single entity level. The method presented relies on the catalytic activity of red blood cells towards hydrogen peroxide and on surface-induced haemolysis. Each single cell activity is expressed as current spikes decaying within a few seconds back to the background current. The frequency of such current spikes is proportional to the concentration of cells in solution.

    Full Text Available A 67-year-old man suffering from esophageal cancer was admitted to our hospital complaining of dyspnea and hypoxemia. He had been treated with cisplatin, docetaxel, and fluorouracil combined with radiotherapy. Chest computed tomography revealed bilateral ground-glass opacity, and bronchoalveolar lavage fluid showed increased eosinophils. Two episodes of transient eosinophilia in peripheral blood were observed after serial administration of anticancer drugs before the admission, and drug-induced lymphocyte stimulation test to cisplatin was positive. Thus cisplatin-induced eosinophilic pneumonia was suspected, and corticosteroid was effectively administered. To our knowledge, this is the first reported case of cisplatin-induced eosinophilic pneumonia.

    Background COPD exacerbations requiring intensive care unit (ICU) admission have a major impact on morbidity and mortality. Only 10%–25% of COPD exacerbations are eosinophilic. Aim To assess whether eosinophilic COPD exacerbations have better outcomes than non-eosinophilic COPD exacerbations in the ICU. Methods This retrospective observational cohort study was conducted in a thoracic, surgery-level III respiratory ICU of a tertiary teaching hospital for chest diseases from 2013 to 2014. Subjects previously diagnosed with COPD and who were admitted to the ICU with acute respiratory failure were included. Data were collected electronically from the hospital database. Subjects’ characteristics, complete blood count parameters, neutrophil to lymphocyte ratio (NLR), delta NLR (admission minus discharge), C-reactive protein (CRP) on admission to and discharge from ICU, length of ICU stay, and mortality were recorded. COPD subjects were grouped according to eosinophil levels (>2% or ≤2%) (group 1, eosinophilic; group 2, non-eosinophilic). These groups were compared with the recorded data. Results Over the study period, 647 eligible COPD subjects were enrolled (62 [40.3% female] in group 1 and 585 [33.5% female] in group 2). Group 2 had significantly higher C-reactive protein, neutrophils, NLR, delta NLR, and hemoglobin, but a lower lymphocyte, monocyte, and platelet count than group 1, on admission to and discharge from the ICU. Median (interquartile range) length of ICU stay and mortality in the ICU in groups 1 and 2 were 4 days (2–7 days) vs 6 days (3–9 days) (P2%. NLR and peripheral eosinophilia may be helpful indicators for steroid and antibiotic management. PMID:26392758

  7. Activity assessment of eosinophilic esophagitis.

    The activity of eosinophilic esophagitis (EoE) can be assessed with patient-reported outcomes and biologic measures. Patient-reported outcomes include symptoms and quality of life, whereas biologic measures refer to endoscopic, histologic, and biochemical activity (e.g. blood biomarkers). So far, a validated tool to assess EoE activity in the above-mentioned dimensions is lacking. Given the lack of a standardized way to assess EoE activity in the various dimensions, the results of different clinical trials may be difficult to compare. For symptom assessment in adult patients, the symptom 'dysphagia' should be evaluated according to different standardized food consistencies. Furthermore, symptom assessment should take into account the following items: avoidance of specific food categories, food modification, and time to eat a regular meal. A distinct symptom recall period (e.g. 2 weeks) has to be defined for symptom assessment. Performing an 'esophageal stress test' with ingestion of a standardized meal to measure symptom severity bears the potential risk of acute food bolus impaction and should therefore be avoided. The description of endoscopic findings in EoE has meanwhile been standardized. Histologic evaluation of EoE activity should report either the size of the high-power field used or count the eosinophils per mm(2). There is a current lack of blood biomarkers demonstrating a good correlation with histologic activity in esophageal biopsies. The development and validation of an adult and pediatric EoE activity index is urgently needed not only for clinical trials and observational studies, but also for daily practice.

    Full Text Available In order to evaluate the potential allergenicity of Blomia tropicalis (Bt antigen, IgE production of both specific and non-specific for Bt antigen was monitored in BALB/c mice after exposure to the antigen by nasal route. It was evidenced that B. tropicalis contains a functional allergen in its components. The allergenic components, however, when administered intranasally without any adjuvant, did not function to induce IgE response within a short period. On the other hand, intranasal inoculation of Bt antigens augmented serum IgE responses in mice pretreated by a subcutaneous priming injection of the same antigens. Inoculation of Bt antigen without subcutaneous priming injections induced IgE antibody production only when the antigen was continuously administered for a long period of over 24 weeks. Even when the priming injection was absent, the Bt antigen inoculated with cholera toxin (CT as a mucosal adjuvant also significantly augmented the Bt antigen-specific IgE responses depending on the dose of CT co-administered. The present study also demonstrated that Bt antigen/CT-inoculated mice showed increased non-specific serum IgE level and peripheral blood eosinophil rates without noticeable elevations of the total leukocyte counts. The immunoblot analysis demonstrated 5 main antigenic components reactive to IgE antibodies induced. These components at about 44-64 kDa position were considered to be an important candidate antigen for diagnosis of the mite-related allergy.Para avaliar a capacidade alergizante do antígeno da Blomia tropicalis (Bt a produção de IgE específica e não específica a antígeno Bt foi monitorada em camundongos BALB/c após exposição ao antígeno por via nasal.

    We present a visualization pipeline from sample to answer for point-of-care blood cell counting applications. Effective and low-cost point-of-care medical diagnostic tests provide developing countries and rural communities with accessible healthcare solutions [1], and can be particularly beneficial for blood cell count tests, which are often the starting point in the process of diagnosing a patient [2]. The initial focus of this work is on total white and red blood cell counts, using a microfluidic cartridge [3] for sample processing. Analysis of the processed samples has been implemented by means of two main optical visualization systems developed in-house: 1) a fluidic operation analysis system using high speed video data to determine volumes, mixing efficiency and flow rates, and 2) a microscopy analysis system to investigate homogeneity and concentration of blood cells. Fluidic parameters were derived from the optical flow [4] as well as color-based segmentation of the different fluids using a hue-saturation-value (HSV) color space. Cell count estimates were obtained using automated microscopy analysis and were compared to a widely accepted manual method for cell counting using a hemocytometer [5]. The results using the first iteration microfluidic device [3] showed that the most simple - and thus low-cost - approach for microfluidic component implementation was not adequate as compared to techniques based on manual cell counting principles. An improved microfluidic design has been developed to incorporate enhanced mixing and metering components, which together with this work provides the foundation on which to successfully implement automated, rapid and low-cost blood cell counting tests.

  13. Machine Learning Based Single-Frame Super-Resolution Processing for Lensless Blood Cell Counting

    2016-11-01

    Full Text Available A lensless blood cell counting system integrating microfluidic channel and a complementary metal oxide semiconductor (CMOS image sensor is a promising technique to miniaturize the conventional optical lens based imaging system for point-of-care testing (POCT. However, such a system has limited resolution, making it imperative to improve resolution from the system-level using super-resolution (SR processing. Yet, how to improve resolution towards better cell detection and recognition with low cost of processing resources and without degrading system throughput is still a challenge. In this article, two machine learning based single-frame SR processing types are proposed and compared for lensless blood cell counting, namely the Extreme Learning Machine based SR (ELMSR and Convolutional Neural Network based SR (CNNSR. Moreover, lensless blood cell counting prototypes using commercial CMOS image sensors and custom designed backside-illuminated CMOS image sensors are demonstrated with ELMSR and CNNSR. When one captured low-resolution lensless cell image is input, an improved high-resolution cell image will be output. The experimental results show that the cell resolution is improved by 4×, and CNNSR has 9.5% improvement over the ELMSR on resolution enhancing performance. The cell counting results also match well with a commercial flow cytometer. Such ELMSR and CNNSR therefore have the potential for efficient resolution improvement in lensless blood cell counting systems towards POCT applications.

    This paper aims at providing a scientific basis for unifying the normal reference value standards of red blood cell count of Chinese presenile men. The paper, using microscopical counting method, studies the relationship between the normal reference values of 38,061 samples of red blood cell count ofpresenile men and eight geographical factors in297 units in China. It is found that the correlation of geographical factors and the normal reference value of red blood cell count of presenile men is quite significant (F=303.00, P=0.000). By using the method of stepwise regression analysis,one regression equation is inferred. It is concluded that if geographical data are obtained in a certain area, the normal reference value of red blood cell count of presenile men in this area can be reckoned by using the regression analysis.Furthermore, according to the geographical factors, China can be divided into eight regions: Northeast China Region,North China Region, Shanxi-Shaanxi-Inner Mongolia Region, Middle and Lower Reaches of the Changjiang River Region, Southeast China Region, Northwest China Region, Southwest China Region and Qinghai-Tibet Plateau Region.

    1999-11-01

    A new non-flowing laser light scattering method for counting and classifying blood cells is presented. A linear charge- coupled device with 1024 elements is used to detect the scattered light intensity distribution of the blood cells. A pinhole plate is combined with the CCD to compete the focusing of the measurement system. An isotropic sphere is used to simulate the blood cell. Mie theory is used to describe the scattering of blood cells. In order to inverse the size distribution of blood cells from their scattered light intensity distribution, Powell method combined with precision punishment method is used as a dependent model method for measurement red blood cells and blood plates. Non-negative constraint least square method combined with Powell method and precision punishment method is used as an independent model for measuring white blood cells. The size distributions of white blood cells and red blood cells, and the mean diameter of red blood cells are measured by this method. White blood cells can be divided into three classes: lymphocytes, middle-sized cells and neutrocytes according to their sizes. And the number of blood cells in unit volume can also be measured by the linear dependence of blood cells concentration on scattered light intensity.

We studied inflammatory biomarkers in the context of reproductive events using National Health and Nutrition Examination Survey (NHANES) data. From 15,986 eligible women from the 1999–2011 data cycles, we accessed information on reproductive events, blood counts, C-reactive protein (CRP), and total homocysteine (tHCY). We calculated blood-count ratios including: platelet-lymphocyte (PLR), lymphocyte-monocyte (LMR), platelet-monocyte (PMR), and neutrophil-monocyte (NMR). Using sampling weights per NHANES guidelines, means for counts, ratios, or biomarkers by reproductive events were compared using linear regression. We performed trend tests and calculated p-values with partial sum of squares F-tests. Higher PLR and lower LMR were associated with nulliparity. In postmenopausal women, lower PMR was associated with early age at first birth and higher NMR with later age at and shorter interval since last birth. Lower PNR and higher neutrophils and tHCY were associated with early natural menopause. In all women, the neutrophil count correlated positively with CRP; but, in premenopausal women, correlated inversely with tHCY. Reproductive events leave residual signatures on blood counts and inflammatory biomarkers that could underlie their links to chronic disease risk. PMID:28234958

    Measures of parasitemia by intraerythrocytic hematozoan parasites are normally expressed as the number of infected erythrocytes per n erythrocytes and are notoriously tedious and time consuming to measure. We describe a protocol for generating rapid counts of nucleated erythrocytes from digital micrographs of thin blood smears that can be used to estimate intensity of hematozoan infections in nonmammalian vertebrate hosts. This method takes advantage of the bold contrast and relatively uniform size and morphology of erythrocyte nuclei on Giemsa-stained blood smears and uses ImageJ, a java-based image analysis program developed at the U.S. National Institutes of Health and available on the internet, to recognize and count these nuclei. This technique makes feasible rapid and accurate counts of total erythrocytes in large numbers of microscope fields, which can be used in the calculation of peripheral parasitemias in low-intensity infections.

    Recent research has raised doubts regarding the utility of serum white blood cell count (WBC) for diagnosis of periprosthetic joint infection (PJI). As synovial WBC and neutrophil (PMN) percentage have been adopted as accurate markers of PJI, this study investigated the correlation of WBC in serum versus joint fluid and diagnostic value of all WBC levels for failed arthroplasty patients. 153 patients (73 PJI) undergoing revision knee arthroplasty were identified. Weak correlations between joint fluid and serum for WBC (R = 0.19), PMN count (R = 0.31), and lymphocyte count (R = -0.22) were observed. Diagnostic accuracy of PMN (93%) and WBC (93%) synovial count relative to serum was similar to synovial WBC (93%) and PMN% (95%) alone. Serum WBC analysis does little to improve the accurate diagnosis of PJI.

    Full Text Available INTRODUCTION Epilepsy is a highly prevalent disease affecting 0.5-1.5% of the world's population. One of the most frequently used antiepileptics are valproates. These medicines show a negative impact on haemostasis and peripheral blood count. OBJECTIVE The objective of the study was to examine the negative impact of valproates on haemostasis and peripheral blood count in children and to analyse whether these disturbances were dependent on the dosage of valproates and drug level in blood. METHOD A two-year research was conducted. The research included: 35 children using valproates, 12 children using the therapy of both valproates and carbamazepine and 30 healthy children. Complete peripheral blood count, screening tests of haemostasis (bleeding time, prothrombin time, prothrombin ratio, activated partial thromboplastin time, fibrinogen and capacity of thrombocyte aggregation research were done in all the children. RESULTS We found significantly more common frequency of leukopenia and neutropenia in children using valproates in comparison with the healthy children group. We also found the more common frequency of eosinophilia in comparison with healthy children. The children with the valproate therapy have lower approximate values of the number of platelets, fibrinogen and platelet aggregation in comparison with healthy children, but they have a higher approximate value of bleeding time and prothrombin time. These disturbances are in correlation with the dosage and the level of the medicine in blood. CONCLUSION Valproates have a negative effect on certain blood count parameters and haemostasis in children. Drug dosage and blood drug level are correlated with their negative impact on haemostasis parameters.

    The avian hemogram is usually performed in veterinary diagnostic laboratories by using manual cell counting techniques and differential counts determined by light microscopy. There is no standard automated technique for avian blood cell count and differentiation to date. These shortcomings in birds are primarily because erythrocytes and thrombocytes are nucleated, which precludes the use of automated analyzers programmed to perform mammal complete blood cell counts. In addition, there is no standard avian antibody panel, which would allow cell differentiation by immunophenotyping across all commonly seen bird species. We report an alternative hematologic approach for quantification and differentiation of avian blood cells by using high-throughput image cytometry on blood smears in psittacine bird species. A pilot study was designed with 70 blood smears of different psittacine bird species stained with a Wright-Giemsa stain. The slides were scanned at 0.23 microm/pixel. The open-source softwares CellProfiler and CellProfiler Analyst were used for analyzing and sorting each cell by image cytometry. A "pipeline" was constructed in the CellProfiler by using different modules to identify and export hundreds of measures per cell for shape, intensity, and texture. Rules for classifying the different blood cell phenotypes were then determined based on these measurements by iterative feedback and machine learning by using CellProfiler Analyst. Although this approach shows promises, avian Leukopet results could not be duplicated when using this technique as is. Further studies and more standardized prospective investigations may be needed to refine the "pipeline" strategy and the machine learning algorithm.

    The proportion and potential risk of concomitant spuriously elevated white blood cell count (SEWC) are underestimated in ethylenediaminetetraacetic acid (EDTA)-dependent pseudothrombocytopenia (PTCP). The proportion, kinetics and prevention of SEWC remain poorly understood. A total of 25 patients with EDTA-dependent PTCP were enrolled in this study. With the hematology analyzer Coulter LH 750, we determined the time courses of WBC count, WBC differential and platelet count in EDTA- and sodium citrate-anticoagulated blood, respectively. Blood smears were prepared to inspect the presence of platelet clumps using light microscopy. The effect of automatic instrumental correction on the extent of SEWC was evaluated. The proportion of SEWC was 92% in EDTA-dependent PTCP and 73.9% of SEWCs were within the normal range. The development of SEWC was time-dependent, and neutrophils and lymphocytes were the main subpopulations involved in SEWC. A strong and significant correlation (r = 0.9937, p EDTA were significantly higher than their basal counts, respectively, p 0.05. A high proportion of concomitant SEWCs, which are mainly within normal range, are present in patients with EDTA-dependent PTCP. Proper interpretation of SEWC is crucial to avoid clinic errors. SEWC develops in a time-dependent pattern, although the Coulter LH 750 only partly mitigates the extent of SEWC, sodium citrate is able to effectively prevent SEWC.

    Background White blood cell count is an independent risk factor for cardiovascular disease. Several lifestyle and metabolic factors such as cigarette smoking and obesity are known to be associated with an elevated white blood cell count. However, the joint effect of cigarette smoking and obesity on white blood cell count has not yet been fully described. Methods We explored the joint effect of cigarette smoking and obesity on white blood cell count using multiple logistic regression analyses after adjusting for confounding variables in a population-based, cross-sectional study of 416,065 Korean adults. Results Cigarette smoking and body mass index have a dose-response relationship with a higher white blood cell count, but no synergistic interaction is observed between them (men, P for interaction=0.797; women, P for interaction=0.311). Cigarette smoking and body mass index might have an additive combination effect on high white blood cell count. Obese male smokers were 2.36 times more likely and obese female smokers 2.35 times more likely to have a high white blood cell count when compared with normal body mass index non-smokers. Conclusion Cigarette smoking and body mass index are independently associated with an elevated white blood cell count in both men and women. PMID:28360982

    Chronic eosinophilic leukemia (CEL) is a very rare form of leucemia in the western world. Adequate response is seldomly achieved after treatment with corticosteroids, interferon-alfa (INF-alfa) and medications containing hydroxi-urea (Litalir). The study presents a patient with CEL with no initial therapeutic response to the use of corticosteroids, INF-alfa and hydroxy-urea, and with neither clinical nor hematological response. After setting a diagnosis of CEL, patient was ordinated Imatinib (Glivec tabbletes) in a daily dose of 200 mg. Two days afterwards there was an evident withdrawal of subjective and clinical symptoms of disease, and the complete blood count showed significant amendment.

    In patients with thrombocytopenia, it can be difficult to predict a patient's bleeding risk based on platelet count alone. Platelet reactivity may provide additional information; however, current clinical assays cannot reliably assess platelet function in the setting of thrombocytopenia. New methods to study platelet reactivity in thrombocytopenic samples are needed. In this study, we sought to develop a laboratory model of thrombocytopenia using blood from healthy subjects that preserves the whole blood environment and reproducibly produces samples with a specific platelet count and hematocrit. We compared the activation state of unstimulated and agonist-stimulated platelets in thrombocytopenic samples derived from this method with normocytic controls. Whole blood was diluted with autologous red blood cell concentrate and platelet-poor plasma, which were obtained via centrifugation, in specific ratios to attain a final sample with a predetermined platelet count and hematocrit. P-selectin exposure and GPIIbIIIa activation in unstimulated platelets and platelets stimulated with collagen-related peptide (CRP) or adenosine diphosphate (ADP) in thrombocytopenic samples and the normocytic control from which they were derived were quantified by flow cytometry. Our methodology reliably produced thrombocytopenic samples with a platelet count ≤50,000/μL and an accurately and precisely controlled hematocrit. P-selectin exposure and GPIIbIIIa activation on unstimulated platelets or on ADP- or CRP-stimulated platelets did not differ in thrombocytopenic samples compared to normocytic controls. We describe a new method for creating thrombocytopenic blood that can be used to better understand the contributions of platelet number and function to hemostasis.

    This study aimed to investigate whether pregnant women with a normal 28-week gestation platelet count and no high-risk conditions for thrombocytopenia require a pre-epidural platelet count. All 1844 included women (platelet count > 150 × 10(9) /L at 28 weeks' gestation, term singleton birth, no thrombocytopenia risk conditions) had a platelet count > 100 × 10(9) /L prebirth, suggesting low-risk pregnant women do not require pre-epidural full blood count solely to check platelet count.

    Peripheral blood cell counts are important biomarkers of radiation exposure. In this work, a simplified compartmental modeling approach is applied to simulate the perturbation of the hematopoiesis system in humans after radiation exposure, and HemoDose software is reported to estimate individuals' absorbed doses based on multi-type blood cell counts. Testing with patient data in some historical accidents indicates that either single or serial granulocyte, lymphocyte, leukocyte, and platelet counts after exposure can be robust indicators of the absorbed doses. In addition, such correlation exists not only in the early time window (1 or 2 d) but also in the late phase (up to 4 wk) after exposure, when the four types of cell counts are combined for analysis. These demonstrate the capability of HemoDose as a rapid point-of-care diagnostic or centralized high-throughput assay system for personnel exposed to unintended high doses of radiation, especially in large-scale nuclear/radiological disaster scenarios involving mass casualties.

    Full Text Available Background. Delivery of full doses of adjuvant chemotherapy on schedule is key to optimal breast cancer outcomes. Neutropenia is a serious complication of chemotherapy and a common barrier to this goal, leading to dose reductions or delays in treatment. While past research has observed correlations between complete blood count data and neutropenic events, a reliable method of classifying breast cancer patients into low- and high-risk groups remains elusive. Patients and Methods. Thirty-five patients receiving adjuvant chemotherapy for early-stage breast cancer under the care of a single oncologist are examined in this study. FOS-3NN stratifies patient risk based on complete blood count data after the first cycle of treatment. All classifications are independent of breast cancer subtype and clinical markers, with risk level determined by the kinetics of patient blood count response to the first cycle of treatment. Results. In an independent test set of patients unseen by FOS-3NN, 19 out of 21 patients were correctly classified (Fisher’s exact test probability P<0.00023 [2 tailed], Matthews’ correlation coefficient +0.83. Conclusions. We have developed a model that accurately predicts neutropenic events in a population treated with adjuvant chemotherapy in the first cycle of a 6-cycle treatment.

    Assessment of platelet count is an important diagnostic parameter in haematology. Automated blood cell counters have largely replaced the manual method. However, all abnormal platelet counts are verified in Leishman's stained peripheral blood smear. Platelets also can be identified in the unstained blood smears. The objective of this study is to compare the unstained peripheral blood smears with the stained smears and determination of the effectiveness of unstained smears in the estimation of platelet count. 250 Venous blood samples sent for blood cell counts were analyzed. Platelets were counted in the unstained smear under 100× objective in 10 fields without placing immersion oil and the average number of platelets was calculated. Same smear was stained by Leishman's stain and platelets were counted under 100× objective after placing a drop of immersion oil. Collected data were analyzed for intra-class correlation coefficient (ICC). ICC showed excellent agreement (ICC > 0.85). The unstained smears were found to be as effective as stained smears for platelet count in most of the cases. However, in case of doubt a stained preparation has to be made to confirm the count. The turnaround time was 3-5 minutes compared to 15-20 minutes by stained smear technique, thus this technique may be used as an initial screening method whenever there is large sample load.

    Objective: To research the formative mechanism of eosinophilic lymphogranuloma (ELG), investigate its essence, provide morphologic base for treatment.Methods: The biopsies and surgical specimens of 41 cases were studied with the light microscope, fluorescein microscope, electron microscope and immunohistochemical methods. In these cases, 10 cases levels of serum IgE were measured, it was high level, and 11 cases cured with radiotherapy. Results: The lesions mainly included proliferation of both lymph tissues and post-capillary venues and formed many new scattered lymph follicles.Marked hyperplasia of plasmocytes and mast cells and diffusible infiltration of eosinophilic granulocytes were observed in tissues. The eosinophilic granulocytes were obviously degranulated. When stained with fluorescein isothiocyanate (FITC) labeled antiserum IgE, the cells showed yellow-green fluorescence, which showed reticular shape in the germinal center of lymph follicles. The swollen tumor-like masses could disappear with radiotherapy, and the eosinophilic granulocytes count in circulation and level of serum IgE reduced to normal.Conclusion: The serum IgE is high lever and it is positive reaction in the tissues strongly. It is accord with allergic granuloma. The lymphocytes are allergenic ambocepotor cells, the x-ray can kill them and stop allergenic agent, the illness was recovered.

    Full Text Available Background. Age-related decrease in bone marrow erythropoietic capacity is often accompanied by the telomere length shortening in peripheral white blood cells. However, limited and conflicting data hamper the conclusive opinion regarding this relationship. Therefore, the aim of this study was to assess an association between telomere length and peripheral blood cell count parameters in the Polish elderly population. Material and Methods. The substudy included 1573 of 4981 subjects aged 65 years or over, participants of the population-based PolSenior study. High-molecular-weight DNA was isolated from blood mononuclear cells. Telomere length (TL was measured by QRT-PCR as abundance of telomere template versus a single gene copy encoding acidic ribosomal phosphoprotein P0. Results. Only white blood count (WBC was significantly different in TL tertile subgroups in all subjects (P=0.02 and in men (P=0.01, but not in women. Merely in men significant but weak positive correlations were found between TL and WBC (r=0.11, P<0.05 and RBC (r=0.08, P<0.05. The multiple regression analysis models confirmed a weak, independent contribution of TL to both RBC and WBC. Conclusions. In the elderly, telomere shortening limits hematopoiesis capacity to a very limited extent.

    Our objective was to develop an effective method to prevent the fall in platelet count for patients with anticoagulant-dependent (AD) pseudothrombocytopenia, a spurious phenomenon due to anticoagulant-induced aggregation of platelets. We report a case of insidious multianticoagulant-dependent pseudothrombocytopenia in which AD pseudothrombocytopenia may be caused by 4 anticoagulants, eg, EDTA, sodium citrate, heparin, and sodium fluoride (NaF). Multianticoagulant-dependent pseudothrombocytopenia was confirmed by finding clumped platelets on microscopic evaluation in 4 anticoagulated blood samples. With this case, we tried a variety of reagents, including aminoglycosides, eg, gentamicin and amikacin, vitamin B(6), and aminophylline to inhibit pseudothrombocytopenia. Except for amikacin, all reagents failed to prevent pseudothrombocytopenia. Microscopic examination of K(2)-EDTA-, heparin-, sodium citrate-, and NaF-anticoagulated blood samples showed massive platelet clumping, but no aggregate was seen in the anticoagulated blood with amikacin. When amikacin was added within 1 hour after blood sample withdrawal, platelet, WBC, and RBC counts and hemoglobin level, mean corpuscular volume, and mean platelet volume remained unchanged for up to 4 hours at room temperature. These findings suggest that amikacin could inhibit and dissociate pseudo platelet aggregation in multianticoagulant-dependent pseudothrombocytopenia and EDTA-induced pseudothrombocytopenia.

    2013-01-01

    Full Text Available Approximately 1 in 5 patients undergoing cardiac surgery are readmitted within 30 days of discharge. Among the primary causes of readmission are infection and disease states susceptible to the inflammatory cascade, such as diabetes, chronic obstructive pulmonary disease, and gastrointestinal complications. Currently, it is not known if a patient’s baseline inflammatory state measured by crude white blood cell (WBC counts could predict 30-day readmission. We collected data from 2,176 consecutive patients who underwent cardiac surgery at seven hospitals. Patient readmission data was abstracted from each hospital. The independent association with preoperative WBC count was determined using logistic regression. There were 259 patients readmitted within 30 days, with a median time of readmission of 9 days (IQR 4–16. Patients with elevated WBC count at baseline (10,000–12,000 and >12,000 mm3 had higher 30-day readmission than those with lower levels of WBC count prior to surgery (15% and 18% compared to 10%–12%, P=0.037. Adjusted odds ratios were 1.42 (0.86, 2.34 for WBC counts 10,000–12,000 and 1.81 (1.03, 3.17 for WBC count > 12,000. We conclude that WBC count measured prior to cardiac surgery as a measure of the patient’s inflammatory state could aid clinicians and continuity of care management teams in identifying patients at heightened risk of 30-day readmission after discharge from cardiac surgery.

    This paper describes a monolithic microfluidic device capable of on-chip sample preparation for both RBC and WBC measurements from whole blood. For the first time, on-chip sample processing (e.g. dilution, lysis, and filtration) and downstream single cell measurement were fully integrated to enable sample preparation and single cell analysis from whole blood on a single device. The device consists of two parallel sub-systems that perform sample processing and electrical measurements for measuring RBC and WBC parameters. The system provides a modular environment capable of handling solutions of various viscosities by adjusting the length of channels and precisely controlling mixing ratios, and features a new 'offset' filter configuration for increased duration of device operation. RBC concentration, mean corpuscular volume (MCV), cell distribution width, WBC concentration and differential are determined by electrical impedance measurement. Experimental characterization of over 100,000 cells from 10 patient blood samples validated the system's capability for performing on-chip raw blood processing and measurement.

    The purpose of this prospective study was to verify the changes in the preoperative and postoperative complete blood counts of patients with surgically treated facial fractures. Fifty consecutive patients with a mean age of 34 years who presented facial fractures and underwent surgical treatment were included. A complete blood count was performed, comprising the red and white blood cell count (cells/μL), hemoglobin (g/dL), and hematocrit (%) levels. These data were obtained preoperatively and postoperatively during a 6-week period. Statistical analyses were performed using the Kruskal-Wallis and Mann-Whitney tests to identify the possible differences among the groups and among the periods of observation using the Friedman and Wilcoxon matched-pairs signed-ranks tests. The most common location of the fractures was the mandible (42.3%), followed by the zygomatic-orbital (36.5%) and associated locations (21.2%). Leukocytosis was associated with neutrophilia in the immediate postoperative period in all of the groups. There were no values below the reference limits of the values of hemoglobin, hematocrit, and erythrocytes, and no values above the reference limits for the remaining white blood cells, although significant differences among periods were observed in most cells, depending on the type of fracture. The primary findings were leukocytosis associated with neutrophilia, verified in the immediate postoperative period in all of the groups, and the influence of the type of fracture on the significant alterations observed among studied periods on the values of hemoglobin, hematocrit, erythrocytes, leukocytes, neutrophils, and lymphocytes.

    The automated laser-based hematology analyzer Sysmex XT-2000iV™ providing a complete blood cell count (CBC) and 5-part differential has been introduced in large veterinary laboratories. The aim of the current study was to determine precision, linearity, and accuracy of the Sysmex analyzer. Reference method for the accuracy study was the laser-based hematology analyzer ADVIA® 2120. For evaluation of accuracy, consecutive fresh blood samples from healthy and diseased cats (n = 216), dogs (n = 314), and horses (n = 174) were included. A low intra-assay coefficient of variation (CV) of approximately 1% was seen for the CBC except platelet count (PLT). An intra-assay CV ranging between 2% and 5.5% was evident for the differential count except for feline and equine monocytes (7.7%) and horse eosinophils (15.7%). Linearity was excellent for white blood cell count (WBC), hematocrit value, red blood cell count (RBC), and PLT. For all evaluated species, agreement was excellent for WBC and RBC, with Spearman rank correlation coefficients (r(s)) ranging from >0.99 to 0.98. Hematocrit value correlated excellently in cats and dogs, whereas for horses, a good correlation was evident. A good correlation between both analyzers was seen in feline and equine PLT (r(s) = 0.89 and 0.92, respectively), whereas correlation was excellent for dogs (r(s) = 0.93). Biases were close to 0 except for mean corpuscular hemoglobin concentration (4.11 to -7.25 mmol/l) and canine PLT (57 × 10(9)/l). Overall, the performance of the Sysmex analyzer was excellent and compared favorably with the ADVIA analyzer.

    Full Text Available BACKGROUND: Walking and cardiovascular mortality are inversely associated in type 2 diabetes, but few studies have objectively measured associations of walking with individual cardiovascular risk factors. Such information would be useful for "dosing" daily steps in clinical practice. This study aimed to quantify decrements in blood pressure and glycated hemoglobin (A1C per 1,000 daily step increments. METHODOLOGY/PRINCIPAL FINDINGS: Two hundred and one subjects with type 2 diabetes underwent assessments of step counts (pedometer-measured, blood pressure, A1C and anthropometric parameters. Due to missing data, the final analysis was conducted on 83 women and 102 men, with a mean age of 60 years. Associations of daily steps with blood pressure and A1C were evaluated using sex-specific multivariate linear regression models (adjusted for age, ethnicity, and BMI. Potential sex differences were confirmed in a combined model (women and men with interaction terms. Mean values for daily steps, blood pressure, A1C and BMI were 5,357 steps/day; 137/80 mm Hg; 7.7% and 30.4 kg/m(2 respectively. A 1,000 daily step increment among women was associated with a -2.6 (95% CI: -4.1 to -1.1 mm Hg change in systolic and a -1.4 (95% CI: -2.2 to -0.6 mm Hg change in diastolic blood pressure. Among men, corresponding changes were -0.7 (95% CI: -2.1 to 0.7 and -0.6 (95% CI: -1.4 to 0.3 mm Hg, respectively. Sex differences were confirmed in combined models. Step counts and A1C did not demonstrate clinically important associations. CONCLUSIONS/SIGNIFICANCE: A 1,000 steps/day increment is associated with important blood pressure decrements among women with type 2 diabetes but the data were inconclusive among men. Targeted "dose increments" of 1,000 steps/day in women may lead to measurable blood pressure reductions. This information may be of potential use in the titration or "dosing" of daily steps. No associations were found between step count increments and A1C.

    A monoclonal antibody to an eosinophil specific determinant is very important in assessing eosinophil function during helminthic infection. Eosinophils induced by Schistosoma mansoni infection in BALB/c mice were used to induce C57B1/6 immunocytes for production of hybridomas secreting eosinophil monoclonal antibodies. These antibodies were shown to react with an eosinophil surface epitope but not with neutrophils or macrophages as determined by ELISA, immunodiffusion, immunofluorescence, and immunoblot assay. Affinity chromatography with eosinophil chemotactic factor-sepharose consistently selected out a { rm M_ R} 67,000 protein from solubilized eosinophil membrane antigens but not from neutrophil and macrophage antigens. In vitro studies showed that the eosinophil-specific monoclonal antibodies abrogated antibody-dependent eosinophil -mediated killing of S. mansoni schistosomula using mouse, rat or human eosinophils. Neutrophil and macrophage killing activities were unaffected. The monoclonal antibodies effected complement-dependent lysis of mouse and rat eosinophils but not of human eosinophils. ECF-treated eosinophils showed enhanced killing of schistosomula which was blocked by the monoclonal antibody. Murine and human eosinophils preincubated with monoclonal antibody exhibited decreased chemotaxis to ECF at optimal chemotactic concentrations. The monoclonal antibody also blocked eosinophil binding to ECF- sepharose beads. In vivo induction of peripheral blood eosinophilia by injection of S. mansoni eggs was suppressed by injections of monoclonal antibodies 2CD13 and 2QD45 in mouse and rat experimental models. Eosinophilia induced by keyhole limpet hemocyanin- cyclophosphamide treatment was also suppressed by monoclonal antibody in both murine and rat systems. Pulmonary granulomas in mice given egg injection and monoclonal antibody were smaller and contained fewer eosinophils than those granulomas from mice given eggs only. In immuno-biochemical studies, the

    Full Text Available The objective of this study was to evaluate the effect of blood and milk zinc concentration on somatic cell count and occurrence of subclinical mastitis cases. The study was performed on thirty Holstein cows approximate same body weight, ages 3 to 5 years, with equally milk production. Blood samples were taken after the morning milking from the caudal vein and milk from all four quarters was taken before morning milking. All samples of blood and milk were taken to determined zinc, using inductively coupled plasma mass spectrometry. 37.67% (11/30 cows have blood serum zinc concentration below 7µmol/l, and 63.33% or 19/30 cows have blood serum zinc concentration higher then 13µmol/l. Also 30% (9/30 cows have somatic cell count lower then 400.000/ml which indicate absence of subclinical mastitis, but 70% (21/30 cows have somatic cell count higher then 400.000/ml which indicate subclinical mastitis. Results indicate that cows with level of zinc in blood serum higher then 13 µmol/l have lower somatic cell count. Cows with lower zinc blood serum concentration then 7 µmol/l have high somatic cell count and high incidence of subclinical mastitis. According to results in this research there is no significant effect of milk serum zinc concentration on somatic cell count in dairy cows.

    Asparaginase, an effective drug in the treatment of childhood acute lymphoblastic leukemia (ALL), has become an important component of most childhood ALL regimens during the remission induction or intensification phases of treatment. The incidence range of asparaginase-associated lipid abnormalities that are seen in children is 67-72%. Lipemia causes erroneous results, which uses photometric methods to analyze blood samples. We describe a case of l-asparaginase-associated severe hyperlipidemia with complete blood count abnormalities. Complete blood count analysis was performed with Beckman COULTER(®) GEN·S™ system, which uses the Coulter Volume, Conductivity, Scatter technology to probe hydrodynamically focused cells. Although an expected significant inaccuracy in hemoglobin determination occurred starting from a lipid value of 3450 mg/dl, we observed that triglyceride level was 1466 mg/dl. Complete blood count analysis revealed that exceptionally high hemoglobin, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration levels vs. discordant with red blood cell count, mean corpuscular volume, and hematocrit levels. Total leukocyte count altered spontaneously in a wide range, and was checked with blood smear. Platelet count was in expected range (Table 1). Thus, we thought it was a laboratory error, and the patient's follow-up especially for red cell parameters was made by red blood cell and hematocrit values.

    There continue to be important concerns about the possibility of the occurrence of acute radiation syndromes following nuclear and radiological terrorism or accidents that may result in mass casualties in densely populated areas. To guide medical personnel in their clinical decisions for effective medical management and treatment of the exposed individuals, biological markers are usually applied to examine radiation induced biological changes to assess the severity of radiation injury to sensitive organ systems. Among these the peripheral blood cell counts are widely used to assess the extent of radiation induced bone marrow injury. This is due to the fact that the hematopoietic system is the most vulnerable part of the human body to radiation damage. Particularly, the lymphocyte, granulocyte, and platelet cells are the most radiosensitive of the blood elements, and monitoring their changes after exposure is regarded as a practical and recommended laboratory test to estimate radiation dose and injury. Based upon years of physiological and pathophysiological investigation of mammalian hematopoietic systems, and rigorous coarse-grained bio-mathematical modeling and validation on species from mouse, to dog, monkey, and human, we have developed a set of software tools Hemodose, which can use single or serial granulocyte, lymphocyte, leukocyte, or platelet counts after exposure to estimate absorbed doses of adult victims very rapidly and accurately. Some patient data from historical accidents are utilized as examples to demonstrate the capabilities of these tools as a rapid point-of-care diagnostic or centralized high-throughput assay system in a large-scale radiological disaster scenario. Most significant to the improvement of national and local preparedness of a potential nuclear/radiological disaster, this HemoDose approach establishes robust correlations between the absorbed doses and victim's various types of blood cell counts not only in the early time window (1

    Diagnosis of MDS has changed during the last years because of the 2008 WHO classification. Complete blood cell count (CBC) is a very important tool both for diagnosis of MDS. The aim of this study was to evaluate if it is possible to use the abnormal signals produced by dysplastic cells to produce a flag "dysplasia" able to identify the patients needing further hematological investigations. The proposed flag has been tested in a large group of patients to evaluate the sensibility and specificity. We create 5 patterns of MDS. Our study demonstrated that the flag "dysplasia" is specific and sensible for MDS.

    Leukopenia is a common manifestation of SLE. Addition of immunosuppressive therapy in a SLE patient who is already leukopenic is a clinical concern. It could worsen leukopenia, increase the risk of infection, or both. The aim of this study was to analyze the immediate effect of mycophenolate mofetil on the white blood cell count and the rate of infection in SLE patients. Two hundred and forty-four patients within the Hopkins Lupus Cohort who were newly started on mycophenolate mofetil were included in the study. The white blood cell count and interval infection history on the day mycophenolate mofetil was started were compared with the white blood cell count and interval infection history at the next visit. The study was based on 244 patients who began taking mycophenolate mofetil in the cohort. The study population included 47 % African Americans, 44 % Caucasians, and 9 % other ethnicities. There was a slight but not statistically significant increase in the white blood cell count (6.63 vs. 7.01), after starting mycophenolate mofetil. Patients with a baseline white blood cell count blood cell count after starting mycophenolate mofetil (2.57 vs. 5.13, P = 0.0047). We also found a statistically significant increase in the risk of bacterial infection (but not viral infection) after starting mycophenolate mofetil (4 vs. 9 %, P = 0.0036). Leukopenia does not worsen with mycophenolate mofetil. However, mycophenolate mofetil appears to slightly increase the rate of bacterial (but not viral) infection.

    Therapeutic delays in cases of external incarcerated hernias typically result in increasing morbidity, mortality, and health expenditures. We investigated the diagnostic role of blood fibrinogen level, white blood count (WBC), mean platelet volume (MPV), and platelet distribution width (PDW) in patients with incarcerated hernia. Two groups, each containing 100 patients, were studied. Group A underwent elective, and group B underwent incarcerated and urgent external hernia repair. We observed high fibrinogen and WBC levels but low MPV and PDW values for patients in group B. Contrary to our expectations, we found lower MPV and PDW values in the complicated group than in the elective group. The morbidity rate and cost burden were higher in group B, and the results were statistically significant. Early operation should be recommended for patients with incarcerated external hernias if their fibrinogen and WBC levels are high.

    All types of blood cells are formed by differentiation from a small self-maintaining population of pluri-potential stem cells in the bone marrow. Despite abundant information on the molecular aspects of division, differentiation, commitment and maturation of these cells, comparatively little is known about the dynamics of the system as a whole, and how it works to maintain this complex ``ecology'' in the observed normal ranges throughout life. Here we report unexpected large, scale-free, fluctuations detected from the first long-term analysis of the day-to-day variability of a healthy animal's blood cell counts measured over one thousand days. This scale-invariance cannot be accounted for by current theoretical models, and resembles some of the scenarios described for self-organized criticality.

    The aim of this study was to investigate the clinical and laboratorial characteristics of splenic marginal zone lymphoma (SMZL) with an abnormal complete blood count (CBC). Data of 19 newly diagnosed SMZL patients with abnormal CBC were analyzed retrospectively. Seven patients were diagnosed by using splenic histology, 12 patients who did not undergo splenectomy were diagnosed on the basis of typical clinical presentation and cytologic, immunophenotypic and histologic characteristics of peripheral blood and bone marrow, according to SBLG guidelines. The results showed that leukocytosis (≥ 10.0×10(9)/L) was seen in 5 cases (26.3%); leukocytopenia (complete response was achieved in 9 out of 11 (81.8%) patients. It is concluded that SMZL with abnormal CBC has a higher incidence of cytopenia, bone marrow involvement and autoimmune phenomena. Therapeutic strategies consisting of Rituximab show a better efficacy.

    morphological changes in juveniles and adults ticks parasitizing animals which consumed the biotherapic. This observation suggests a negative interference of the biotherapic in the biological cycle of the tick, decreasing its population and consequently his control’s necessity. Comparing the blood cells counts of the first and the twelfth month, a raise of 23% (P> 0.05 in the eosinophils and 8% (P< 0.05 in the platelets was observed in the T1 animals. No changes in liver enzymes were observed. The increase in eosinophils and platelets found in this experiment suggests that biotherapic ingested by the animals strengthens the defense system and the clotting cascade.Key words: bovinos

    The possible role of exposure to radiation as a risk factor for human health has been of increasing public concern in the series of explosions at earthquake damaged nuclear reactors on the Japan. Current events throughout the world underscore the growing threat of different forms of accidental exposure to radiation including nuclear accidents, atomic weapons use and testing, and the side effects of cancer therapy. A large range of dose rates of ionizing radiations could be encountered in accidental radiation situations. Nevertheless, most of the studies related to radiation effects have only examined a high dose rate. In this study, we investigated the blood count and the cytokine levels in the serum of mice exposed to a high or low dose rate of radiation. In this study, the precise molecular mechanism underlying the low dose rate of radiation remains unclear, but differential hematopoietic effects of radiation exposed at a high dose rate versus low dose rate were observed using the number of peripheral blood count and serum cytokines. These data suggest that chronic low dose rate exposure caused a stimulation of heamatopoietic system occurrence, unlike those observed after higher dose rate exposure. Our data suggest that the dose rate, rather than the total dose, may be more critical in causing damage to the cellular hematopoietic compartments of the body.

    Recent studies have shown that there is a relationship between some inflammatory and biochemical markers derived from complete blood count (CBC) such as neutrophil/lymphocyte (N/L) ratio, platelet/lymphocyte (P/L) ratio, platelet distribution width (PDW), red blood cell distribution width (RDW), and coronary artery disease (CAD). The aim of this study was to determine N/L ratio, P/L ratio, PDW values, and RDW values, which are associated with myocardial perfusion in patients diagnosed with CAD. This study included 262 patients (149 with myocardial ischemia/infarction and 113 with normal myocardial perfusion) undergoing myocardial perfusion scintigraphy (MPS) with CBC within 90 days of MPS. Myocardial perfusion parameters such as summed stress score and summed difference score (SDS) were compared with N/L ratio, P/L ratio, PDW values, and RDW values. Neutrophil counts and N/L ratios were significantly higher in patients diagnosed with myocardial ischemia and/or infarct. However, there was no statistically significant relationship between myocardial perfusion abnormalities and P/L ratio, PDW values, and RDW values. This study showed that N/L ratio is related to myocardial ischemia/infarction and correlated to left ventricular ejection fraction (LVEF).

    We have examined the influence of erythrocytes containing inclusion bodies, nucleated red cells or giant platelets on the measurement of reticulocyte count by automated machine, R-1000. Correlation of the reticulocyte count between automated and conventional method was extremely good in the blood containing red cells with Jolly bodies, Pappenheimer bodies or basophilic stippling . However, correlation was poor when the sample contained the nucleated red cells. Reticulocyte count was decreased in the blood with significant amounts of nucleated red cells. Since nucleated red cells themselves are not counted as reticulocytes in the machine, this was considered to be due to increased young reticulocytes which frequently appeared with nucleated red cells. Both cold agglutinated red cells and giant platelets apparently influenced the reticulocyte count by the R-1000. These results suggest that red cells with Jolly bodies, Pappenheimer bodies or basophilic stippling do not influence the automatic counting of reticulocytes. Although nucleated red cells, cold agglutinated red cells and giant platelets affected the reticulocyte count, the machine shows abnormal flags in most of above cases (except highly agglutinated red cells), so that one can recount reticulocytes by conventional method. We conclude the machine can safely count the reticulocytes even in the blood containing abnormal red cells or platelets.

    Full Text Available Abstract. A role of intracellular proteins of eosinophils and mast cells remains unclear in the patients with hematological neoplasia. There is a substantial evidence that eosinophils possess some common mechanisms of cooperation with mast cells. Therapeutic interventions into key events controlling eosinophil migration may be a leading factor in treatment of hypereosinophylic states in onco-hematological disorders. Due to unknown functions of eosinophils in majority of eosinophilia-associated diseases, it would be useful to establish an algorithm of accurate diagnostics in the patients with eosinophilia, in order to choose more effective treatment in future.We studied serum levels of secretable eosinophil and mast cells proteins in oncohematological patients with increased eosinophil counts. The aim of our study was to test a significance of quantitative assay for tryptase and ECP in the patients with myelo- and lymphoproliferative diseases. The study group included thirty-eight patients with oncohematological diseases, accompanied by a marked eosinophilia (> 0.4 x 109/L. Eighteen patients with bronchial asthma (BA, and eight cases of solid tumors comprised a reference group for polyclonal eosinophilia. The levels of ECP and tryptase were measured in blood serum using a commercial fluoroimmunoenzyme assay («Pharmacia», Uppsala, Sweden. Total ECP levels were markedly increased in general group with hematological malignancies (p < 0.03, , and in cases of chronic GvHD (p < 0.03, and in a sub-group with lymphoproliferative disorders (р = 0.007 as compared to the group of non-hematological diseases.Serum levels of tryptase were significantly increased in the patients with chronic GvHD after allo-HSCT and lymphoproliferative diseases, as compared to the group of patients with solid tumors (р = 0.03, as well in GvHD compared with lymphoproliferative disorders (р < 0.05.A direct correlation was found between serum ECP levels and absolute

    Bullous pemphigoid (BP) is an autoimmune blistering disease mediated by autoantibodies targeting BP180 (type XVII collagen). Patient sera and tissues typically have IgG and IgE autoantibodies and elevated eosinophil numbers. Although the pathogenicity of the IgE autoantibodies is established in BP, their contribution to the disease process is not well understood. Our aims were two-fold: 1) To establish the clinical relationships between total and BP180-specific IgE, eosinophilia and other markers of disease activity; and 2) To determine if eosinophils from BP patients express the high affinity IgE receptor, FcεRI, as a potential mechanism of action for IgE in BP. Our analysis of 48 untreated BP patients revealed a correlation between BP180 IgG and both BP180 IgE and peripheral eosinophil count. Additionally, we established a correlation between total IgE concentration and both BP180 IgE levels and eosinophil count. When only sera from patients (n = 16) with total IgE≥400 IU/ml were analyzed, BP180 IgG levels correlated with disease severity, BP230 IgG, total circulating IgE and BP180 IgE. Finally, peripheral eosinophil count correlated more strongly with levels of BP180 IgE then with BP180 IgG. Next, eosinophil FcεRI expression was investigated in the blood and skin using several methods. Peripheral eosinophils from BP patients expressed mRNA for all three chains (α, β and γ) of the FcεRI. Surface expression of the FcεRIα was confirmed on both peripheral and tissue eosinophils from most BP patients by immunostaining. Furthermore, using a proximity ligation assay, interaction of the α- and β-chains of the FcεRI was observed in some biopsy specimens, suggesting tissue expression of the trimeric receptor form in some patients. These studies provide clinical support for the relevance of IgE in BP disease and provide one mechanism of action of these antibodies, via binding to the FcεRI on eosinophils. PMID:25255430

    We report the sixth case of Eosinophilic Mastitis, presenting similarly enough to be confused with breast carcinoma. A 50 year old lady presented with a six month history of progressively enlarging asymptomatic breast lump, cough and breathlessness. Clinical examination, mammography and axillary lymphadenopathy suggested malignant disease. Ronchi were heard on chest auscultation. Needle cytology was twice inconclusive and Tru-cut biopsy showed acute on chronic inflammation. Blood investigations revealed significant peripheral eosinophilia. Open biopsy reported eosinophilic mastits, correlating with peripheral eosinophilia and pulmonary symptoms. The patient responded to conservative management. Eosinophilic infiltration of the breast is a rare manifestation of tissue involvement in peripheral eosinophilia. Asthma, Churgh-Strauss Syndrome and hyper-eosinophilic syndromes are associated. Importantly, if a clinically and radiologically malignant breast lump in asthmatic ladies with peripheral eosinophilia is not confirmed on cytology, this entity could be a diagnosis, potentially saving the patient from surgery.

In this study, we conducted a cross-sectional study of men who participated in health check-ups, and selected those who were not diagnosed with or being treated for metabolic diseases such as diabetes, hypertension and lipid abnormality according to the health check-ups. We measured their basic clinical parameters including blood pressure and neutrophil count, plasma sE-selectin concentration and lifestyle factors, and assessed their interrelations by multivariate linear regression (MLR) analysis. A total of 351 subjects aged 47.5±8.41 (range, 30-64) y were recruited. Significantly correlated with sE-selectin concentration were neutrophil count, diastolic blood pressure (DBP), and systolic blood pressure (SBP) (Pearson's correlation coefficient, 0.194, 0.220 and 0.175, respectively). MLR analysis showed that sE-selectin concentration was independently positively related with DBP and neutrophil count, whereas neutrophil count was positively associated with sE-selectin concentration but not DBP. DBP, but not SBP, was independently positively correlated with sE-selectin concentration but not neutrophil count. These results indicate that circulating sE-selectin concentration may be a biomarker for indicating subsequent development of metabolic diseases, in particular CVD, from a healthy state.

    We assessed the acute effects of a 1-h exposure to second-hand smoke (SHS) on complete blood count (CBC) markers in a controlled simulated bar/restaurant environment. Nineteen adult never-smokers completed a 1-h .exposure to SHS at bar/restaurant levels, and a 1-h exposure to normal room air. Blood samples were collected at the baseline at 30 min during each exposure, and at 0, 0.5, 1, 2, 3, and 4 h after each exposure. The values of white blood cells (WBC) at 1 h (p = 0.010), 3 h (p = 0.040), and 4 h (p = 0.008) following SHS were significantly increased compared with the baseline values. Also, there was a positive association between the WBC and cotinine levels (r = 0.28, p = 0.007). A 1-h exposure to SHS at bar/restaurant levels significantly increased the WBC for at least 4 h following the exposure time. This effect of SHS on WBC has dose-response characteristics and should be considered to prescribing CBC.

    The conventional method of estimating parasite densities employ an assumption of 8000 white blood cells (WBCs)/μl. However, due to leucopenia in malaria patients, this number appears to overestimate parasite densities. In this study, we assessed the accuracy of parasite density estimated using this assumed WBC count in eastern Myanmar, where Plasmodium vivax has become increasingly prevalent. From 256 patients with uncomplicated P. vivax malaria, we estimated parasite density and counted WBCs by using an automated blood cell counter. It was found that WBC counts were not significantly different between patients of different gender, axillary temperature, and body mass index levels, whereas they were significantly different between age groups of patients and the time points of measurement. The median parasite densities calculated with the actual WBC counts (1903/μl) and the assumed WBC count of 8000/μl (2570/μl) were significantly different. We demonstrated that using the assumed WBC count of 8000 cells/μl to estimate parasite densities of P. vivax malaria patients in this area would lead to an overestimation. For P. vivax patients aged five years and older, an assumed WBC count of 5500/μl best estimated parasite densities. This study provides more realistic assumed WBC counts for estimating parasite densities in P. vivax patients from low-endemicity areas of Southeast Asia.

    Tanabe, Rikiya; Hata, Seiichi; Shimokohbe, Akira

    To develop a miniature complete blood count (CBC) analyzer for point-of-care testing (POCT), a MEMS CBC sensor based on the impedance method is discussed. A novel MEMS CBC sensor that is fabricated through a simple photolithography process using SU-8 is realized. However, the fabricated sensor exhibits a noisy output signal due to electrolysis gas. The relationship between the noise and the gas is revealed through microscopic observation and finite element method (FEM) simulation. To solve the problem of electrolysis gas, an improved MEMS CBC sensor with vanes is developed. The improved sensor is unaffected by electrolysis gas. Moreover, the signal stability of the sensor and the signals detected for latex particles are successfully evaluated.

    In this paper we overview a method to automatically count morphologically normal red blood cells (RBCs) by using off-axis digital holographic microscopy and statistical methods. Three kinds of RBC are used as training and testing data. All of the RBC phase images are obtained with digital holographic microscopy (DHM) that is robust to transparent or semitransparent biological cells. For the determination of morphologically normal RBCs, the RBC's phase images are first segmented with marker-controlled watershed transform algorithm. Multiple features are extracted from the segmented cells. Moreover, the statistical method of Hotelling's T-square test is conducted to show that the 3D features from 3D imaging method can improve the discrimination performance for counting of normal shapes of RBCs. Finally, the classifier is designed by using statistical Bayesian algorithm and the misclassification rates are measured with leave-one-out technique. Experimental results show the feasibility of the classification method for calculating the percentage of each typical normal RBC shape.

This means that the condition of individuals must be related to or compared with reference data. Determination of a reference range for the healthy term newborn is clinically important in terms of various complete blood count parameters. The purpose of this study was to establish a local reference range for full blood count parameters in neonatal cord plasma in Hilla, Babil, Iraq.Methods: A total of 220 mothers and their neonates were enrolled in this cross-sectional study from February 2011 to January 2012. Maternal inclusion criteria were age 15–45 years, an uneventful pregnancy, and hemoglobin ≥ 10 g. Neonatal inclusion criteria were full term (37–42 weeks and normal birth weight. The umbilical cord was immediately clamped after delivery of the baby; 3 mL of cord blood was then taken from the umbilical vein and collected in a tube containing ethylenediamine tetra-acetic acid, its plasma was analyzed for full blood count parameters by standard Coulter gram, and the differential leukocyte count was done manually.Results: Mean neonatal hemoglobin was 13.88 ± 1.34 (range 11–17.3 g/dL and mean white cell count was 10.12 ± 2.8 (range 3.1–21.6 × 109/L. Mean platelet count was 267.63 ± 60.62 (range 152–472 × 109/L. No significant differences in red cell, white cell, or platelet counts were found between males and females, except for neutrophil count. The current study shows lower levels of hemoglobin, white cells, and red cells compared with other studies, and there is agreement with some studies and disagreement with others concerning platelet count.Conclusion: Most results

    The diagnosis of myelodysplastic syndromes (MDS) requires a high clinical index of suspicion to prompt bone marrow studies as well as subjective assessment of dysplastic morphology. We sought to determine if data collected by automated hematology analyzers during complete blood count (CBC) analysis might help to identify MDS in a routine clinical setting. We collected CBC parameters (including those for research use only and cell population data) and demographic information in a large (>5,000), unselected sequential cohort of outpatients. The cohort was divided into independent training and test groups to develop and validate a random forest classifier that identifies MDS. The classifier effectively identified MDS and had a receiver operating characteristic area under the curve (AUC) of 0.942. Platelet distribution width and the standard deviation of red blood cell distribution width were the most discriminating variables within the classifier. Additionally, a similar classifier was validated with an additional, independent set of >200 patients from a second institution with an AUC of 0.93. This retrospective study demonstrates the feasibility of identifying MDS in an unselected outpatient population using data routinely collected during CBC analysis with a classifier that has been validated using two independent data sets from different institutions.

    Full Text Available Abstract Background Mammalian cells transform into individual tubular straw cells naturally in tissues and in response to desiccation related stress in vitro. The transformation event is characterized by a dramatic cellular deformation process which includes: condensation of certain cellular materials into a much smaller tubular structure, synthesis of a tubular wall and growth of filamentous extensions. This study continues the characterization of straw cells in blood, as well as the mechanisms of tubular transformation in response to stress; with specific emphasis placed on investigating whether tubular transformation shares the same signaling pathway as apoptosis. Results There are approximately 100 billion, unconventional, tubular straw cells in human blood at any given time. The straw blood cell count (SBC is 45 million/ml, which accounts for 6.9% of the bloods dry weight. Straw cells originating from the lungs, liver and lymphocytes have varying nodules, hairiness and dimensions. Lipid profiling reveals severe disruption of the plasma membrane in CACO cells during transformation. The growth rates for the elongation of filaments and enlargement of rabbit straw cells is 0.6~1.1 (μm/hr and 3.8 (μm3/hr, respectively. Studies using apoptosis inhibitors and a tubular transformation inhibitor in CACO2 cells and in mice suggested apoptosis produced apoptotic bodies are mediated differently than tubular transformation produced straw cells. A single dose of 0.01 mg/kg/day of p38 MAPK inhibitor in wild type mice results in a 30% reduction in the SBC. In 9 domestic animals SBC appears to correlate inversely with an animal's average lifespan (R2 = 0.7. Conclusion Straw cells are observed residing in the mammalian blood with large quantities. Production of SBC appears to be constant for a given animal and may involve a stress-inducible protein kinase (P38 MAPK. Tubular transformation is a programmed cell survival process that diverges from apoptosis

    Full Text Available Introduction: In order to carry out an autologous transplantation, hematopoietic stem cells should be mobilized to peripheral blood and later collected by apheresis. The CD34+ cell count is a tool to establish the optimal time to begin the apheresis procedure. Objective: To evaluate the association between peripheral blood CD34+ cell count and the successful collection of hematopoietic stem cells. Materials and methods: A predictive test evaluation study was carried out to establish the usefulness of peripheral blood CD34+ cell count as a predictor of successful stem cell collection in patients that will receive an autologous transplantation. Results: 77 patients were included (median age: 49 years; range: 5-66. The predominant baseline diagnosis was lymphoma (53.2 %. The percentage of patients with successful harvest of hematopoietic stem cells was proportional to the number of CD34+cells in peripheral blood at the end of the mobilization procedure. We propose that more than 15 CD34+cells/μL must be present in order to achieve an adequate collection of hematopoietic stem cells. Conclusion: Peripheral blood CD34+ cell count is a useful tool to predict the successful collection of hematopoietic stem cells.

However, few studies have evaluated the association of RBC count with microvascular complications in patients with type 2 diabetes mellitus (T2DM. The purpose of this study was to investigate the association of RBC count with microvascular complications in patients with T2DM.Methods: This study involved 369 patients with T2DM: 243 with one or more microvascular complications and 126 without microvascular complications. Anticoagulated blood was collected and analyzed in an automated blood cell counter. The presence of risk factors for microvascular complications was determined.Results: The proportion of patients with microvascular complications increased as the RBC count decreased (P < 0.001. After adjustment for known risk factors for microvascular complications by logistic regression analysis, lower quartiles of RBC count were associated with a higher risk of microvascular complications compared with the reference group composed of the highest quartile (first quartile, odds ratio 4.98, 95% confidence interval 1.54–6.19, P = 0.008; second quartile, odds ratio 3.21, 95% confidence interval 1.17–5.28, P = 0.024.Conclusion: A decreased RBC count is associated with microvascular complications in Chinese patients with T2DM. The RBC count is a potential marker to improve further the ability to identify diabetic patients at high risk of microvascular complications.Keywords: red blood cell count, microvascular complication, type 2 diabetes

    2016-01-01

    Eosinophilic fasciitis is a systemic inflammatory disease characterized by symmetrical swelling and skin induration of the distal portions of the arms and/or legs, evolving into a scleroderma-like appearance, accompanied by peripheral blood eosinophilia. It is a rare disease with a poorly understood etiology. Corticosteroid treatment remains the standard therapy, either taken alone or in association with an immunosuppressive drug. This paper presents a case of a male patient with palpebral edema and marked eosinophilia, diagnosed with intestinal parasitic infection in October 2006. He was treated with an antiparasitic drug, but both the swelling and the analytical changes remained. This was followed by a skin and muscle biopsy, which turned out to be compatible with eosinophilic fasciitis. There was progressive worsening of the clinical state, with stiffness of the abdominal wall and elevated inflammatory parameters, and the patient was referred to the Immunology Department, medicated with corticosteroids and methotrexate. Over the years there were therapeutic adjustments and other causes were excluded. Currently the patient continues to be monitored, and there is no evidence of active disease. The case described in this article is interesting because of the diagnosis of eosinophilic fasciitis probably associated/coexisting with a parasite infection. This case report differs from others in that there is an uncommon cause associated with the onset of the disease, instead of the common causes such as trauma, medication, non-parasitic infections or cancer.

    Full Text Available Introduction: Increased numbers of nucleated red blood cells (NRBC circulating in the blood of neonates can be associated with relative hypoxia and adverse outcomes. Thus, the aim of this study was to assess the NRBC count during the first week of life in neonates diagnosed with asphyxia as compared to healthy neonates and to determine the short-term morbidity and mortality for the affected babies. Methods: The cross-sectional study compared 15 healthy neonates with 15 neonates diagnosed with asphyxia confirmed by pH of cord blood or Apgar scores. The nucleated red blood cell (NRBC counts were calculated right after birth, and on days 3 and 7, and the hematological parameters of umbilical cord blood were also evaluated. The infants were followed for mortality and associated morbidity. Statistical analysis was conducted using the Mann-Whitney U test, analysis of variance, chi-square tests, and Pearson’s correlation coefficient. A p-value < 0.05 was considered as statistically significant. Results: The initial NRBC counts were significantly higher in the asphyxiated group than in the control group and the difference remained significant through the end of first week. All of the umbilical cord blood parameters were significantly lower in the study group and were negatively correlated with the NRBC count. At birth, higher NRBC count correlated with higher mortality. conclution: Results show that NRBC count is a useful predictive factor for neonatal asphyxia through the end of the first week of life, although a larger study population and a longer follow up period seems to be necessary.

    Introduction It is well known that the efficacy of intravenous (IV) tissue plasminogen activator (tPA) is time-dependent when used to treat patients with acute ischemic strokes. Aim Our study examines the safety issue of giving IV tPA without complete blood count (CBC) resulted. Materials and Methods This is a retrospective observational study by examining the database from Huashan Hospital in China and OSF/INI Comprehensive Stroke Center in United States. Patient data collected included demographics, occurrence of symptomatic intracranial hemorrhage, door to needle intervals, National Institute of Health Stroke Scale scores on admission, CBC results on admission and follow-up modified Rankin Scale scores. Linear regression and multivariable logistic regression analysis were used to identify factors that would have an impact on door-to-needle intervals. Results Our study included120 patients from Huashan Hospital and 123 patients from INI. Among them, 36 in Huashan Hospital and 51in INI received IV tPA prior to their CBC resulted. Normal platelet count was found in 98.8% patients after tPA was given. One patient had thrombocytopenia but no hemorrhagic event. A significantly shorter door to needle interval (DTN) was found in the group without CBC resulted. There was also a difference in treatment interval between the two hospitals. Door to needle intervals had a strong correlation to onset to treatment intervals and NIHSS scores on admission. Conclusion In patients presented with acute ischemic stroke, the risk of developing hemorrhagic event is low if IV tPA is given before CBC has resulted. The door to needle intervals can be significantly reduced. PMID:26147994

    Eosinophilic gastroenteritis is considered an uncommon disease with a low incidence rate that remains as a diagnostic challenge for the clinician, in spite of the fact that seventy years have passed since its original description. Hereby we present the case of a 29-year-old male without history of allergies who was evaluated for unspecific gastrointestinal symptoms, without relevant findings on physical examination and presenting an initial complete blood count (CBC) with severe eosinophilia. The patient was evaluated and the diagnosis of eosinophilic gastroenteritis was confirmed by histopathological findings. The relevance of the case resides in highlighting the lack of guidelines or consensus for histological diagnosis being virtually the only one available. To a similar extent, treatment evidence is based on case series with a reasonable number of patients and case reports. PMID:26075112

    Bee pollen is given to children by mothers in order to strengthen their immune systems. There are no studies related with the side effects of bee polen in the literature. In this article, the literature was reviewed by presenting a case of allergic eosinophilic gastropathy related with bee polen. A 5-year old child was admitted due to abdominal pain. Edema was detected on the eyelids and pretibial region. In laboratory investigations, pathology was not detected in terms of hepatic and renal causes that would explain the protein loss of the patient diagnosed with hypoproteinemia and hypoalbuminemia. Urticaria was detected during the follow-up visit. When the history of the patient was deepened, it was learned that bee pollen was given to the patient every day. The total eosinophil count was found to be 1 800/mm(3). Allergic gastroenteropathy was considered because of hypereosinophilia and severe abdominal pain and endoscopy was performed. Biopsy revealed abundant eosinophils in the whole gastric mucosa. A diagnosis of allergic eosinophilic gastropathy was made. Bee polen was discontinued. Abdominal pain and edema disappeared in five days. Four weeks later, the levels of serum albumin and total eosinophil returned to normal.

    Analysis of the association between antibodies against bovine leukemia virus (BLV), BLV proviral load, and white blood cell (WBC) and lymphocyte counts was performed with 774 dairy cows. The average age, WBC counts and lymphoid cell counts tended to be higher in BLV antibody-positive cows than in antibody-negative cows. There was a similar trend in levels of proviral DNA. We analyzed age, WBC counts and lymphocyte counts by principal component analyses to create a distribution chart of the principle component scores. Using the chart, we categorized cows into four quadrants based on additional information, such as the presence of antibody and the levels of proviral DNA. Antibody-positive cows and cows with high BLV proviral load were found mostly in one quadrant of the chart, indicating that it is possible to predict the risk of infection without any knowledge on antibody status by using information, such as WBC counts as a biomarker. When only antibody-positive cows were included in the analysis, a characteristic distribution of different levels of proviral DNA was seen in the quadrants, suggesting that it is possible to estimate the extent of bovine leukosis infection by using this analysis. For this analysis and categorization of the cows into quadrants, we computed a mathematical formulation using discriminant analysis based on age and WBC and lymphocyte counts. This mathematical formulation for the hematological preliminary diagnosis of the disease is recommended as a screening tool to monitor bovine leukosis. PMID:27064146

    Background & aims Red blood cell (RBC) indices have been demonstrated to be associated with fatty liver disease (FLD) and metabolic syndrome. However, controversy exists regarding the relationship of RBC indices with FLD to date and few has focused on RBC count. This study aimed to explore the association between RBC count and risk of FLD in Southern Chinese adults. Methods A hospital-based cross-sectional study was performed in two hospital health examination centers, including information on ultrasonography-diagnosed FLD, anthropometric indices and biochemical measurements. Covariance analysis was used to evaluate group differences. After quintile classification of RBC counts, logistic regression analysis was conducted to evaluate the odds ratios (ORs) of FLD. Results This study consisted of 8618 subjects (4137 men and 4481 women) aged between 20 and 89 years. FLD cases had higher RBC counts than non-FLD cases in both genders (Pwomen. Binary logistic regression analysis showed positive association between RBC count and FLD, and the OR (95% confidence interval (CI)) were 2.56 (2.06–3.18) in men and 3.69 (2.74–4.98) in women, respectively, when comparing Q5 with Q1. Stratified analyses showed similar trends among subjects with and without FLD risk factors. Gender independent results were similar to gender dependent results. Conclusions Elevated RBC count is independently associated with high risk of FLD, suggesting that the RBC count may be a potential risk predictor for FLD. PMID:28187211

    Platelets play a crucial role in hemostasis. Their activation has not yet been evaluated in healthy dogs with a normal and low platelet count. The aim of this study was to determine the influence of activators on platelet activation in dogs with a normal platelet count and asymptomatic thrombocytopenia. 72 clinically healthy dogs were enrolled. Patients were allocated into three groups. Group 1 consisted of 30 dogs with a normal platelet count, group 2 included 22 dogs with a platelet count between 100 and 200×109/l and group 3 consisted of 20 dogs with a platelet count lower than 100×109/l. Platelet rich-plasma (PRP) was obtained from peripheral blood samples using tripotassium ethylenediaminetetraacetic acid (K3-EDTA) as anticoagulant. Next, platelets were stimulated using phorbol-12-myristate-13-acetate or thrombin, stabilized using procaine or left unstimulated. The expression of CD51 and CD41/CD61 was evaluated. Co-expression of CD41/CD61 and Annexin V served as a marker of platelet activation. The expression of CD41/CD61 and CD51 did not differ between the 3 groups. Thrombin-stimulated platelets had a significantly higher activity in dogs with a normal platelet count than in dogs with asymptomatic thrombocytopenia. Procaine inhibited platelet activity in all groups. In conclusion, activation of platelets of healthy dogs in vitro varied depending on the platelet count and platelet activator.

    Leukocytes normally marginate toward the vascular wall in large vessels and within the microvasculature. Reversal of this process, leukocyte demargination, leads to substantial increases in the clinical white blood cell and granulocyte count and is a well-documented effect of glucocorticoid and catecholamine hormones, although the underlying mechanisms remain unclear. Here we show that alterations in granulocyte mechanical properties are the driving force behind glucocorticoid- and catecholamine-induced demargination. First, we found that the proportions of granulocytes from healthy human subjects that traversed and demarginated from microfluidic models of capillary beds and veins, respectively, increased after the subjects ingested glucocorticoids. Also, we show that glucocorticoid and catecholamine exposure reorganizes cellular cortical actin, significantly reducing granulocyte stiffness, as measured with atomic force microscopy. Furthermore, using simple kinetic theory computational modeling, we found that this reduction in stiffness alone is sufficient to cause granulocyte demargination. Taken together, our findings reveal a biomechanical answer to an old hematologic question regarding how glucocorticoids and catecholamines cause leukocyte demargination. In addition, in a broader sense, we have discovered a temporally and energetically efficient mechanism in which the innate immune system can simply alter leukocyte stiffness to fine tune margination/demargination and therefore leukocyte trafficking in general. These observations have broad clinically relevant implications for the inflammatory process overall as well as hematopoietic stem cell mobilization and homing.

    A 16–year–old male presented with urinary urgency, a frequency of 4 months duration and intermittent gross haematuria which were there since one month. Eosinophilia was noted in complete blood count and CT KUB with contrast showed a filling defect in the right lateral wall, over the vesicoureteric junction. Cystoscopy revealed a sessile mass lesion over right vesico–ureteric junction, with bullous oedema . Rest of the mucosa was normal. Transurethral resection of lesion was performed and histological examination showed features of eosinophilic cystitis. Patient was treated with corticosteroids, antimicrobial agents and antihistaminics and he is recovering well. We are presenting this case for its rare presentation and its possibility of mimicking a bladder tumour. Biopsy of the lesion was diagnostic and an early treatment showed good results. PMID:24298501

  10. The Eosinophil in Infection.

    2016-04-01

    First described by Paul Ehrlich in 1879, who noted its characteristic staining by acidophilic dyes, for many years, the eosinophil was considered to be an end-effector cell associated with helminth infections and a cause of tissue damage. Over the past 30 years, research has helped to elucidate the complexity of the eosinophil's function and establish its role in host defense and immunity. Eosinophils express an array of ligand receptors which play a role in cell growth, adhesion, chemotaxis, degranulation, and cell-to-cell interactions. They play a role in activation of complement via both classical and alternative pathways. Eosinophils synthesize, store and secrete cytokines, chemokines, and growth factors. They can process antigen, stimulate T cells, and promote humoral responses by interacting with B cells. Eosinophils can function as antigen presenting cells and can regulate processes associated with both T1 and T2 immunity. Although long known to play a role in defense against helminth organisms, the interactions of eosinophils with these parasites are now recognized to be much more complex. In addition, their interaction with other pathogens continues to be investigated. In this paper, we review the eosinophil's unique biology and structure, including its characteristic granules and the effects of its proteins, our developing understanding of its role in innate and adaptive immunity and importance in immunomodulation, and the part it plays in defense against parasitic, viral, fungal and bacterial infections. Rather than our worst enemy, the eosinophil may, in fact, be one of the most essential components in host defense and immunity.

    of DP has remained unclear. We report in this study that, in addition to CRTH2, the DP receptor plays an important role in eosinophil trafficking. First, we investigated the release of eosinophils from bone marrow using the in situ perfused guinea pig hind limb preparation. PGD2 induced the rapid...... that eosinophils in human bone marrow specimens expressed DP and CRTH2 receptors at similar levels. Eosinophils isolated from human peripheral blood likewise expressed DP receptor protein but at lower levels than CRTH2. In agreement with this, the chemotaxis of human peripheral blood eosinophils was inhibited both...

    This paper is the first report whether or not pneumatic tube system affects the selection of apheresis donors according to the results of complete blood count. According to the apheresis guidelines, hemoglobin level must be ≥12.5g/dL and platelet level ≥150/μL to be a donor. Paired blood samples of 26 healthy volunteers were transported by either hand delivered or a pneumatic tube system to the laboratory. No statistically significant differences were observed in order to mean values of routine complete blood cell count and white cell differential parameters that were send for selection of apheresis donor before the procedure. Therefore, all healthy volunteers decided as a donor according to the laboratory results independent from transport method.

    Counting morphologically normal cells in human red blood cells (RBCs) is extremely beneficial in the health care field. We propose a three-dimensional (3-D) classification method of automatically determining the morphologically normal RBCs in the phase image of multiple human RBCs that are obtained by off-axis digital holographic microscopy (DHM). The RBC holograms are first recorded by DHM, and then the phase images of multiple RBCs are reconstructed by a computational numerical algorithm. To design the classifier, the three typical RBC shapes, which are stomatocyte, discocyte, and echinocyte, are used for training and testing. Nonmain or abnormal RBC shapes different from the three normal shapes are defined as the fourth category. Ten features, including projected surface area, average phase value, mean corpuscular hemoglobin, perimeter, mean corpuscular hemoglobin surface density, circularity, mean phase of center part, sphericity coefficient, elongation, and pallor, are extracted from each RBC after segmenting the reconstructed phase images by using a watershed transform algorithm. Moreover, four additional properties, such as projected surface area, perimeter, average phase value, and elongation, are measured from the inner part of each cell, which can give significant information beyond the previous 10 features for the separation of the RBC groups; these are verified in the experiment by the statistical method of Hotelling's T-square test. We also apply the principal component analysis algorithm to reduce the dimension number of variables and establish the Gaussian mixture densities using the projected data with the first eight principal components. Consequently, the Gaussian mixtures are used to design the discriminant functions based on Bayesian decision theory. To improve the performance of the Bayes classifier and the accuracy of estimation of its error rate, the leaving-one-out technique is applied. Experimental results show that the proposed method can

    Full Text Available Abstract Background Smoking has been linked to low-grade systemic inflammation, a known risk factor for disease. This state is reflected in elevated white blood cell (WBC count. Objective We analyzed the relationship between WBC count and smoking in healthy men and women across several age ranges who underwent preventive medical check-ups in the workplace. We also analysed the relationship between smoking and lung function. Methods Cross-sectional descriptive study in 163 459 men and 59 382 women aged between 16 and 70 years. Data analysed were smoking status, WBC count, and spirometry readings. Results Total WBC showed higher counts in both male and female smokers, around 1000 to 1300 cell/ml (t test, P 1% was higher in nonsmokers for both sexes between 25 to 54 years (t test, P 1% were found to have higher WBC counts, in comparison to smokers with a normal FEV1% among similar age and BMI groups. Conclusions Smoking increases WBC count and affects lung function. The effects are evident across a wide age range, underlining the importance of initiating preventive measures as soon as an individual begins to smoke.

    Resveratrol is a phytoestrogen that has many beneficial actions. This study aimed to evaluate the effect of resveratrol on the complete blood count (CBC) and the acetylcholinesterase (AChE) activity of lymphocytes of ovariectomized rats experimentally demyelinated by ethidium bromide (EB). Forty adult female Wistar rats (60 days, 200-220 g) were divided randomly into five groups (n = 4) to evaluate the demyelination phase and five groups (n = 4) to evaluate the remyelination phase. In each phase, the groups consisted of sham rats-G1; ovariectomized rats, not demyelinated, treated only with vehicle (ethanol 25%)-G2; demyelinated ovariectomized rats treated only with vehicle-G3; ovariectomized rats, not demyelinated, treated with resveratrol-G4; and demyelinated ovariectomized rats treated with resveratrol-G5. Only during the remyelination phase, CBC showed a significant difference (p < 0.05) in the number of monocytes between G2 and G5 groups. In the demyelination phase, there was a significant decrease (p < 0.05) in the AChE activity in the G4 group, while the G5 group was statistically similar to the G1, G2 and G4 groups. In the remyelination phase, there were no significant differences in the AChE activity among the groups. The treatment for 7 days with resveratrol with or without the experimental demyelization with EB appears to influence the AChE activity of lymphocytes, without changing the number of these cells in the circulation. However, in the remyelination phase, there seems to be stabilization in its effect on the lymphocyte AChE activity.

    A 34-year-old Spanish woman with a lifelong history of seasonal rhinoconjunctivitis and honey intolerance (pyrosis and abdominal pain) developed, 3 weeks after starting ingestion of bee pollen, astenia, anorexia, abdominal pain, diarrhoea, peripheral blood hypereosinophilia and elevated serum total IgE levels. A duodenal biopsy showed eosinophilic infiltration of the mucosal layer. Other causes of hypereosinophilia were not found. Repeated parasitological stool studies, as well as a duodenal aspirate showed negative results. Symptoms, hypereosinophilia and elevated IgE levels resolved after bee pollen ingestion was stopped. This is a typical case of eosinophilic gastroenteritis by ingestion of bee pollen in a woman with intolerance to honey bee, because the patient fulfilled the usual diagnostic criteria: gastrointestinal symptoms were present, eosinophilic infiltration of the digestive tract was demonstrated by biopsy, no eosinophilic infiltration of other organs was found and the presence of parasites was excluded. Honey intolerance and/or bee pollen administration should be considered as a cause of eosinophilic gastroenteritis.

    Full Text Available Aim: The present study was aimed to study the use of cell counts as an early indicator of mammary health. Materials and Methods: Milk and blood cell counts were estimated from 8 healthy, 8 subclinical (SCM, and 8 clinically mastitis (CM groups of Karan Fries (KF cows. Results: Total leucocyte counts and neutrophil percent in blood and milk somatic cells and milk neutrophil percent of healthy cows increased significantly (p<0.05 in SCM cows and CM cows. Viability of blood and milk neutrophils was more in healthy cows, but decreased significantly (p<0.05 in SCM and CM cows. Significant (p<0.05 decrease were also observed in both the blood and milk lymphocytes and monocytes of SCM and CM cows. Phagocytic activity (PA of blood neutrophils also decreased significantly (p<0.05 in SCM cows. There was no difference between the PA of SCM and CM cows. Milk neutrophil percent was more in the SCM and clinically infected milk than in the blood of these cows. About 96-97% of the neutrophils had segmented nucleus in both healthy and subclinical milk, whereas, 2-3% were having band shaped or immature nuclei. There was a significant decrease in the segmented neutrophils, whereas, band neutrophils increase significantly to about 5% in the infected milk of mastitic cows. Viability of the milk neutrophils decreased more in case of subclinical and clinical milk as compared to that of blood. PA was found to be highest in the milk of healthy group of cows, but decreased significantly (p<0.05 in subclinically infected cows. However, there was no difference between the PA of milk neutrophils of SCM and CM cows. PA of milk was also found to be significantly lower in the milk of healthy cows when compared to that of blood neutrophils. Conclusion: This study indicated that percent neutrophils and their type in conjunction with milk somatic cell counts can be used as a more reliable indicator of mammary health in cows.

    The role of white blood cell (WBC) count in pathogenesis of diabetes, cardiovascular disease, and obesity-related disorders has been reported earlier. Recent studies revealed that higher WBC contributes to atherosclerotic progression and impaired fasting glucose. However, it is unknown whether variations in WBC and haematologic profiles can occur in healthy obese individuals. The aim of this study is to further evaluate the influence of obesity on WBC count, inflammatory biomarkers, and metabolic risk factors in healthy women to establish a relationship among variables analyzed. The sample of the present study consisted of 84 healthy women with mean age of 35.56 +/- 6.83 years. They were categorized into two groups based on their body mass index (BMI): obese group with BMI > 30 kg/m2 and non-obese group with BMI count (PLT) with serum interleukin 6 (IL-6), C-reactive protein (CRP), angiotensin pi (Ang pi), body fat percentage (BF %), waist-circumference (WC), and lipid profile. WBC, PLT, CRP, and IL-6 in obese subjects were significantly higher than in non-obese subjects (p count in obese subjects was 6.4 +/- 0.3 (x10(9)/L) compared to 4.4 +/- 0.3 (x10(9)/L) in non-obese subjects (p = 0.035). WBC correlated with BF% (r = 0.31, p = 0.004), CRP (r = 0.25, P = 0.03), WC (r = 0.22, p = 0.04), angiotensin 11 (r = 0.24, p = 0.03), triglyceride (r = 0.24, p = 0.03), and atherogenic index of plasma (AIP) levels (r = 0.3, p = 0.028) but not with IL-6. Platelet count was also associated with WC and waist-to-hip ratio (p count and inflammatory parameters. There was also a positive relationship between WBC count and several inflammatory and metabolic risk factors in healthy women.

    A significant association between elevated white blood cell (WBC) count and mortality in patients with cancer has been reported, but the predictive value of elevated WBC on mortality in cancer patients with acute venous thromboembolism (VTE) has not been explored. RIETE is an ongoing registry of consecutive patients with acute VTE. We compared the three-month outcome of cancer patients with acute VTE according to their WBC count at baseline. As of May 2007, 3805 patients with active cancer and acute VTE had been enrolled in RIETE. Of them, 215 (5.7%) had low- (11,000 cells/microl) WBC count. During the study period 190 patients (5.0%) had recurrent VTE, 156 (4.1%) major bleeding, 889 (23%) died (399 of disseminated cancer, 113 of PE, 46 of bleeding. Patients with elevated WBC count at baseline had an increased incidence of recurrent VTE (odds ratio [OR]: 1.6; 95% confidence interval [CI]: 1.2-2.2), major bleeding (OR: 1.5; 95% CI: 1.1-2.1) or death (OR: 2.7; 95% CI: 2.3-3.2). Most of the reported causes of death were significantly more frequent in patients with elevated WBC count. Multivariate analysis confirmed that elevated WBC count was independently associated with an increased incidence of all three complications. In conclusion, cancer patients with acute VTE and elevated WBC count had an increased incidence of VTE recurrences, major bleeding or death. This worse outcome was consistent among all subgroups and persisted after multivariate adjustment.

    Since the advent of automation in the field of hematological cell counters there has been a constant refinement of the technology and increase in the number of newer parameters available on CBC analysers. Many novel parameters are being put into routine clinical use and both clinical evaluation and monitoring critically depend on knowledge of laboratory reference ranges. Here, we present reference interval for the Sysmex XE-2100, with emphasis on the novel or newer research parameters. Blood samples from a total of 122 clinically asymptomatic and apparently healthy subjects were evaluated and a final of 100 subjects (54-M, 46-F) were included in the study. A broad spectrum of parameters available with the analyser was assessed and reference ranges for the same evaluated.

    Background The Metabolic Syndrome (MetS) is a cluster of metabolic abnormalities that includes hyperglucemia, hypertension, dyslipidemia and central obesity, conferring an increased risk of cardiovascular disease. The white blood cell (WBC) count has been proposed as a marker for predicting cardiovascular risk. However, few prospective studies have evaluated the relationship between WBC subtypes and risk of MetS. Methods Participants were recruited from seven PREDIMED study centers. Both a baseline cross-sectional (n = 4,377) and a prospective assessment (n = 1,637) were performed. Participants with MetS at baseline were excluded from the longitudinal analysis. The median follow-up was 3.9 years. Anthropometric measurements, blood pressure, fasting glucose, lipid profile and WBC counts were assessed at baseline and yearly during the follow-up. Participants were categorized by baseline WBC and its subtype count quartiles. Adjusted logistic regression models were fitted to assess the risk of MetS and its components. Results Of the 4,377 participants, 62.6% had MetS at baseline. Compared to the participants in the lowest baseline sex-adjusted quartile of WBC counts, those in the upper quartile showed an increased risk of having MetS (OR, 2.47; 95%CI, 2.03–2.99; P-trend<0.001). This association was also observed for all WBC subtypes, except for basophils. Compared to participants in the lowest quartile, those in the top quartile of leukocyte, neutrophil and lymphocyte count had an increased risk of MetS incidence. Leukocyte and neutrophil count were found to be strongly associated with the MetS components hypertriglyceridemia and low HDL-cholesterol. Likewise, lymphocyte counts were found to be associated with the incidence of the MetS components low HDL-cholesterol and high fasting glucose. An increase in the total WBC during the follow-up was also associated with an increased risk of MetS. Conclusions Total WBC counts, and some subtypes, were positively

    Early detection of iron deficiency (ID) and iron deficiency anemia (IDA) in young children is important to prevent impaired neurodevelopment. Unfortunately, many biomarkers of ID are influenced by infection, thus limiting their usefulness. The aim of this study was to investigate the value of red blood cell distribution width (RDW) and the platelet count for detecting ID(A) among otherwise healthy children. A multicenter prospective observational study was conducted in the Netherlands to investigate the prevalence of ID(A) in 400 healthy children aged 0.5-3 years. ID was defined as serum ferritin (SF) count were determined in the complete blood cell count. RDW was inversely correlated with SF and not associated with CRP. Calculated cutoff values for RDW to detect ID and IDA gave a relatively low sensitivity (53.1% and 57.1%, respectively) and specificity (64.7% and 69.9%, respectively). Anemic children with a RDW >14.3% had a 2.7 higher odds (95% confidence interval [CI]: 1.2-6.3) to be iron deficient, compared with anemic children with a RDW count showed a large range in both ID and non-ID children. In conclusion, RDW can be helpful for identifying ID as the cause of anemia in 0.5- to 3-year-old children, but not as primary biomarker of ID(A). RDW values are not influenced by the presence of infection. There appears to be no role for the platelet count in diagnosing ID(A) in this group of children.

    Purpose: Radiation pneumonitis (RP) is an inflammatory response to radiation therapy (RT). We assessed the association between RP and white blood cell (WBC) count, an established metric of systemic inflammation, after RT for non-small cell lung cancer. Methods and Materials: We retrospectively analyzed 366 patients with non-small cell lung cancer who received ≥60 Gy as definitive therapy. The primary endpoint was whether WBC count after RT (defined as 2 weeks through 3 months after RT completion) was associated with grade ≥3 or grade ≥2 RP. Median lung volume receiving ≥20 Gy (V{sub 20}) was 31%, and post-RT WBC counts ranged from 1.7 to 21.2 × 10{sup 3} WBCs/μL. Odds ratios (ORs) associating clinical variables and post-RT WBC counts with RP were calculated via logistic regression. A recursive-partitioning algorithm was used to define optimal post-RT WBC count cut points. Results: Post-RT WBC counts were significantly higher in patients with grade ≥3 RP than without (P<.05). Optimal cut points for post-RT WBC count were found to be 7.4 and 8.0 × 10{sup 3}/μL for grade ≥3 and ≥2 RP, respectively. Univariate analysis revealed significant associations between post-RT WBC count and grade ≥3 (n=46, OR=2.6, 95% confidence interval [CI] 1.4‒4.9, P=.003) and grade ≥2 RP (n=164, OR=2.0, 95% CI 1.2‒3.4, P=.01). This association held in a stepwise multivariate regression. Of note, V{sub 20} was found to be significantly associated with grade ≥2 RP (OR=2.2, 95% CI 1.2‒3.4, P=.01) and trended toward significance for grade ≥3 RP (OR=1.9, 95% CI 1.0-3.5, P=.06). Conclusions: Post-RT WBC counts were significantly and independently associated with RP and have potential utility as a diagnostic or predictive marker for this toxicity.

    Aurora Flight Sciences, in partnership with Draper Laboratory, has developed a miniaturized system to count white blood cells in microgravity environments. The system uses MEMS technology to simultaneously count total white blood cells, the five white blood cell differential subgroups, and various lymphocyte subtypes. The OILWBCS-MEMS detection technology works by immobilizing an array of white blood cell-specific antibodies on small, gold-coated membranes. When blood flows across the membranes, specific cells' surface protein antigens bind to their corresponding antibodies. This binding can be measured and correlated to cell counts. In Phase I, the partners demonstrated surface chemistry sensitivity and specificity for total white blood cells and two lymphocyte subtypes. In Phase II, a functional prototype demonstrated end-to-end operation. This rugged, miniaturized device requires minimal blood sample preparation and will be useful for both space flight and terrestrial applications.

    Full Text Available OBJECTIVE: To review the literature for clinical data on infants with allergic or eosinophilic colitis. DATA SOURCE: MEDLINE search of all indexes was performed using the words ''colitis or procto-colitis and eosinophilic'' or ''colitis or proctocolitis and allergic'' between 1966 and February of 2013. All articles that described patients' characteristics were selected. DATA SYNTHESIS: A total of 770 articles were identified, of which 32 met the inclusion criteria. The 32 articles included a total of 314 infants. According to the available information, 61.6% of infants were male and 78.6% were younger than 6 months. Of the 314 patients, 49.0% were fed exclusively breast milk, 44.2% received cow's milk protein, and 6.8% received soy protein. Diarrheal stools were described in 28.3% of patients. Eosinophilia was found in 43.8% (115/263 of infants. Colonic or rectal biopsy showed infiltration by eosinophils (between 5 and 25 perhigh-power field in 89.3% (236/264 of patients. Most patients showed improvement with theremoval of the protein in cow's milk from their diet or the mother's diet. Allergy challenge tests with cow's milk protein were cited by 12 of the 32 articles (66 patients. CONCLUSIONS: Eosinophilic colitis occurs predominantly in the first six months of life and in males. Allergy to cow's milk was considered the main cause of eosinophilic colitis. Exclusion of cow'smilk from the diet of the lactating mother or from the infant's diet is generally an effective therapeutic measure.

    Tests were conducted to prove that muscular exertion (in this instance swimming) of different duration and intensity, as well as hypodynamia, result in an increase of hemoglobin and number of red blood cells in peripheral blood rats. Catalase activity increased with an increase in the duration of swimming, but only up to 6 hr; with 7-9 hr of swimming as well as in hypodynamia, catalase activity decreased. It was also observed that under hypodynamia as well as in 3, 5 and 6 hr exertion (swimming) the color index of blood decreased. Pressure chamber treatment (for 8 min each day for one week), alternating a 2 min negative pressure up to 35 mm Hg with 1 min positive pressure, increased the erythrocyte count and hemoglobin content.

    Full Text Available Eosinophilic fasciitis (EF is a rare disorder involving chronic inflammation of the fascia and connective tissue surrounding muscles, nerves, and blood vessels. While its pathogenesis is not entirely understood, this disorder is thought to be autoimmune or allergic in nature. We present here a case of a 59-year-old male who developed peripheral eosinophilia and subsequent eosinophilic fasciitis during treatment with infliximab. To our knowledge, eosinophilic fasciitis has not been previously described in patients during treatment with an inhibitor of tumor necrosis factor α.

    Full Text Available Recent studies reported seasonal differences in gene expression in white blood cells, adipose tissue, and inflammatory biomarkers of the immune system. There is no data on the seasonal variations of these biomarkers in the US general population of both children and adults. Then aim of this study is to explore the seasonal trends in complete blood count (CBC, and C-reactive protein (CRP in a large non-institutionalized US population.Seven cross-sectional data collected in the National Health and Nutrition Examination Survey (NHANES during 1999-2012 were aggregated; participants reporting recent use of prescribed steroids, chemotherapy, immunomodulators and antibiotics were excluded. Linear regression models were used to compare levels of CBC and CRP between winter-spring (November-April and summer-fall (May-October, adjusting for demographics, personal behavioral factors, and chronic disease conditions.A total of 27,478 children and 36,644 adults (≥18 years were included in the study. Levels of neutrophils, white blood cell count (WBC, and CRP were higher in winter-spring than summer-fall (p≤0.05. Red blood cell components were lower in winter-spring than in summer-fall, while the opposite was seen for platelets.This large population-based study found notable seasonal variations in blood cell composition and inflammatory biomarkers, with a more pro-inflammatory immune system seen in winter-spring than summer-fall. The red blood cell patterns could have implications for the observed cardio-vascular seasonality.

    The normal content of eosinophils in the adult colon and the criteria for the histopathologic diagnosis of eosinophilic colitis remain undefined. This study aimed at: (1) establishing the numbers of eosinophils in the normal adult colon; and (2) proposing a clinicopathologic framework for the diagnosis of primary colonic eosinophilia and eosinophilic colitis. To accomplish these goals, we counted the eosinophils in the right, transverse, and left colon of 159 adults with normal colonic histology. Using a database of 1.2 million patients with colonic biopsies, we extracted all adults with a diagnosis of colonic eosinophilia. We reviewed the slides from all cases and captured demographic, clinical, and pathologic data, including information about eosinophilia in other organs. We then compared the clinical manifestations of the study patients (those with no identifiable cause of eosinophilia) to those of patients with other types of colitis. The normal eosinophil counts (per mm) were 55.7±23.4 in the right, 41.0±18.6 in the transverse, and 28.6±17.2 in the left colon. Of the 194 study patients (eosinophil counts 166-5050/mm), 63 were asymptomatic and had a normal colonoscopy. Diarrhea and abdominal pain were the commonest indications for colonoscopy (38% and 27%, respectively) among the 131 patients who had symptoms, endoscopic abnormalities, or both. Neither clinical manifestations nor endoscopic appearance were sufficiently characteristic to elicit the suspicion of colonic eosinophilia. In conclusion, primary colonic eosinophilia was extremely rare in this series (reporting high colonic eosinophilia may result in increased opportunities for clinicopathologic studies that might lead to a better definition of this still elusive entity.

    Cell counting in human body fluids such as blood, urine, and CSF is a critical step in the diagnostic process for many diseases. Current automated methods for cell counting are based on flow cytometry systems. However, these automated methods are bulky, costly, require significant user expertise, and are not well suited to counting cells in fluids other than blood. Therefore, their use is limited to large central laboratories that process enough volume of blood to recoup the significant capital investment these instruments require. We present in this talk a combination of a (1) low-cost microscope system, (2) simple sample preparation method, and (3) fully automated analysis designed for providing cell counts in blood and body fluids. We show results on both humans and companion and farm animals, showing that accurate red cell, white cell, and platelet counts, as well as hemoglobin concentration, can be accurately obtained in blood, as well as a 3-part white cell differential in human samples. We can also accurately count red and white cells in body fluids with a limit of detection ~3 orders of magnitude smaller than current automated instruments. This method uses less than 1 microliter of blood, and less than 5 microliters of body fluids to make its measurements, making it highly compatible with finger-stick style collections, as well as appropriate for small animals such as laboratory mice where larger volume blood collections are dangerous to the animal's health.

    Veterinarians rely on results of both the complete blood cell count (CBC) and plasma protein electrophoresis (EPH) in conjunction with the results of the plasma biochemical analysis to evaluate the health status of avian patients. Because the CBC and protein EPH measure different aspects of the immune response to disease, both tests are recommended in avian patients to rule out infectious or inflammatory disease. To evaluate results of the CBC and protein EPH in pet psittacine birds, the records of 144 pet psittacine birds, comprising 11 genera, that were presented for suspected illness were reviewed. Results of the CBC (total white blood cell count and packed cell volume) and protein EPH (alpha, beta, and gamma globulin concentrations) from submitted blood samples from each bird were evaluated. Of the 144 birds, 63 (43.8%) had abnormal CBC results, and 25 (17.4%) had abnormal EPH measurements. Results of the CBC and protein EPH were within reference ranges in 73 birds (50.7%). Abnormal results of the CBC in conjunction with normal EPH results were present in 46 birds (31.9%), compared with 8 birds (5.6%) with normal results of the CBC and abnormal EPH results. The findings of this study could aid practitioners in evaluating psittacine patients and prioritizing the value of individual diagnostic tests.

    Full Text Available Considering the incidence of meconium-stained amniotic fluid (MSAF in newborns and its complications, and also based on indirect reports pointing out relationship between nucleated red blood cell (nRBC, as a marker of chronic hypoxia, and MSAF in term newborns, and in order to determine this relationship more accurately, this study was done on women with uncomplicated singleton term pregnancy that admitted for delivery at Shariati hospital in year 2000. After excluding confounding factors on nRBC, case group who includes infants with MSAF, and control group who have clear amniotic fluid were determined. Maternal age and parity, gestational age, birth weight, apgar score, neonatal out come, and FHR pattern as well as newborn hemoglobin values were evaluated. Venous cord blood was analyzed for nRBC counts per 100 WBC. Case and control groups were divided according to nRBC counts with cutoff point of 10 and then compared statistically. From the samples, 117 cases and 67 controls were evaluated. Maternal and neonatal factors were similar in two situations. Number of nRBC was 3.75±4.8 in control group and 12.04±11.7 in case group (P<0.01 and it was abnormal (>10 in 9 percent of newborns with clear fluid and 32 percent of MSAF (P<0.01. Cord blood nRBC count increased when meconium is passed intrauterine. This suggests that cases with MSAF may be at risk of chronic hypoxia. Cohort research is recommended to study the affect of delivery mode on the neonatal outcome in cases with MSAF and to evaluate the cause of fetal hypoxia in uncomplicated pregnancy with MSAF.

    Objective: To observe changes in RBC count, changes, RBC morphology, and serum potassium during compressed transfusion of WBC-removal whole blood. Methods: Prepared human WBC-removal whole blood and connected transfusion apparatus with different sizes of intravenous detaining needles ( 18G, 20G, 22G and 24G) . Observed RBC count and serum potassium concentration under different pressures ( 100 mmHg, 200 mmHg, and 300 mmHg) as blood flowed out of the pinhead end of the intravenous detaining needle. Samples ob-tained with the 20G needle were smeared on glass slides, and RBC morphologic changes were ob-served under an oil immersion lens. Results: RBC count and serum potassium changed slightly under different pressures with differ-ent sizes of intravenous detaining needles as blood flowed through the transfusion apparatus. In ad-dition, the observation of blood samples under a common light microscope revealed that coarse-prick, oblong, and spindle cell counts in the visual fields increased gradually as the pressure in-creased. Additionally, a portion of cells had undergone splintering. Conclusions: While applying 18G, 20G, 22G and 24G intravenous detaining needles for blood transfusion under less than 300 mmHg of pressure, no significant RBC count change was found in blood samples in the short term. However, there were significant RBC morphologic changes. The results could offer more basis to ensure the clinical safety of patients undergoing blood transfusion.

    Full Text Available Abstract Background Cigarette smokers have increased white blood cell (WBC counts and the activation of tumor necrosis factor (TNF. The effect of smoking on WBC counts and TNF system activity, however, has not been separately investigated yet. Subjects and Methods One hundred and forty-two Japanese male subjects with normal glucose tolerance were recruited. They were stratified into two groups based on the questionnaire for smoking: one with current smokers (n = 48 and the other with current non-smokers (n = 94. Whereas no significant differences were observed in age, BMI, high molecular weight (HMW adiponectin, and TNF-α between the two groups, current smokers had significantly higher soluble TNF receptor 1 (sTNF-R1 (1203 ± 30 vs. 1116 ± 21 pg/ml, p = 0.010 and increased WBC counts (7165 ± 242 vs. 5590 ± 163/μl, p p = 0.031 as compared to current non-smokers. Next, we classified 48 current smokers into two subpopulations: one with heavy smoking (Brinkman index ≥ 600 and the other with light smoking (Brinkman index Results Whereas no significant difference was observed in age, BMI, HMW adiponectin, WBC counts and TNF-α, sTNF-R1 and sTNF-R2 were significantly higher in heavy smoking group (1307 ± 44 vs. 1099 ± 30 pg/ml, p p = 0.005 than in light smoking group, whose sTNF-R1 and sTNF-R2 were similar to non-smokers (sTNF-R1: 1116 ± 15 pg/ml, p = 0.718, sTNF-R2; 1901 ± 32 pg/ml, p = 0.437. In contrast, WBC counts were significantly increased in heavy (7500 ± 324/μl, p p = 0.001 smoking group as compared to non-smokers (5590 ± 178/μl. There was no significant difference in WBC counts between heavy and light smoking group (p = 0.158. Conclusion We can hypothesize that light smoking is associated with an increase in WBC counts, while heavy smoking is responsible for TNF activation in Japanese male subjects with normal glucose tolerance.

    Full Text Available The leading pathophysiological changes during sepsis include systemic abnormalities in the immune
    response. Due to the general character of these disturbances, sepsis is usually studied as a homogenous clinical
    condition. We aimed to compare the immune response in intraabdominal sepsis (IAS and pneumonia-derived
    sepsis (PDS. The following cell populations were examined: white blood cell count (WBC, monocytes, lymphocytes:
    CD3+, CD4+ and CD8+ T cells, B cells, and NK cells. In both studied groups (i.e. IAS and PDS, the
    WBC was elevated. However, it was significantly higher in the IAS group than in the PDS group. The difference
    was due to a lower granulocyte count, as well as a lower monocyte count in PDS. We found no significant
    correlation between the total lymphocyte number and CD3+CD8+ T cells in either form of sepsis. Similarly, we
    observed no correlation between the total lymphocyte number and the NK cells subset in IAS. However, the
    numbers of CD3+CD8+ and NK cells correlated similarly in both types of sepsis. Both studied types of sepsis
    induced profound lymphocytopenia, with marked loss of CD8+ T cells and the NK cells. However, the similar
    relation between them, which was independent of the infection type, suggests that the NK and CD3+CD8+ cells
    have shared mechanisms of regulation. The primary site of infection has an impact on the global immune reaction.
    These alternations include especially myeloid cells: granulocytes and monocytes which disappear from peripheral
    blood during PDS, but increase in IAS.

    Full Text Available The rapid growth in microelectronics and crunching RISC in the field of bio-medical sciences incorporated of soft tools to diagnose various parameters of human fluids. Conventional method of blood sample analysis makes use of laboratory technique of titration, which is operator-dependent and results in lot of errors depending on the skill of the technician. In order to eliminate the human errors involved in the conventional method, in this paper an attempt has been made to present a capillary centrifuge technique driven by high speed DC motor fed by Morgan chopper and controlled by powerful ARM processor. It results in accurate analysis of the blood samples. The various techniques involved in accurate sensing of speed using timer and generation of firing pulses to thyristor in the Morgan chopper is judiciously achieved. This paper clearly brings out the advantages of the proposed blood measurement technique which effectively gives blood analysis faster and at a low cost.

    Eosinophilic plaque and mosquito-bite dermatitis are recognized hypersensitivity reactions. The pathogenesis of eosinophilic granuloma and indolent ulcer are not as clearly understood. Each of these syndromes is distinctive from a clinical and histopathologic view point. Accurate diagnosis depends on history, physical findings, and histopathologic evaluation. Understanding of feline dermatology will be furthered by including these syndromes in a broader grouping that encompasses all the feline eosinophilic dermatoses.

    Expression of CD56 has recently been introduced as one of the adverse prognostic factors in acute promyelocytic leukemia (APL). However, the clinical significance of CD56 antigen in APL has not been well elucidated. We assessed the clinical significance of CD56 antigen in 239 APL patients prospectively treated with all-trans retinoic acid and chemotherapy according to the Japan Adult Leukemia Study Group APL97 protocol. All patients were prospectively treated by the Japan Adult Leukemia Study Group APL97 protocol. The median follow-up period was 8.5 years. Positive CD56 expression was found in 23 APL patients (9.6%). Expression of CD56 was significantly associated with lower platelet count (P = 0.04), severe disseminated intravascular coagulation (P = 0.04), and coexpression of CD2 (P = 0.03), CD7 (P = 0.04), CD34 (P < 0.01) and/or human leukocyte antigen-DR (P < 0.01). Complete remission rate and overall survival were not different between the two groups. However, cumulative incidence of relapse and event-free survival (EFS) showed an inferior trend in CD56(+) APL (P = 0.08 and P = 0.08, respectively). Among patients with initial white blood cell counts of 3.0 × 10(9)/L or more, EFS and cumulative incidence of relapse in CD56(+) APL were significantly worse (30.8% vs 63.6%, P = 0.008, and 53.8% vs 28.9%, P = 0.03, respectively), and in multivariate analysis, CD56 expression was an unfavorable prognostic factor for EFS (P = 0.04). In conclusion, for APL with higher initial white blood cell counts, CD56 expression should be regarded as an unfavorable prognostic factor.

    Abstract Radioactive iodine (RAI) is considered to be related with hematologic changes. This study aimed to evaluate influence of the first RAI ablation on peripheral complete blood count (CBC) in patients with differentiated thyroid cancer (DTC). Data of CBC at baseline and 6 months after RAI were obtained in 385 patients with DTC with approximately 3700 MBq 131I (ranging 2220–7585 MBq). Further comparison was done in 196 patients with 1-month postablation data available. Routine blood examinations were performed to determine impact of RAI on white blood cell (WBC), red blood cell (RBC), hemoglobin, platelet, neutrophil, lymphocyte, and monocyte in both sexes. Continuous variables were compared by paired t tests and independent samples t test, and categorical variables were compared by chi-square analysis. Data with repeated measurements were analyzed by analysis of variance. The first RAI after thyroidectomy was associated with mild, yet significant declines in WBC, platelet, and lymphocyte, which persisted for 6 months. One month after RAI, significant declines were found in all CBC, including RBC and hemoglobin (all P DTC. PMID:27583853

    AIM: To evaluate the clinic features of eosinophilicgastroenteritis and to examine the diagnosis, treatment,long-term outcome of this disease.METHODS: Charts with a diagnosis of eosinophilicgastroenteritis from 1984 to 2002 at Mackay Memorial Hospital were reviewed retrospectively. There were 15 patients diagnosed with eosinophilic gastroenteritis. The diagnosis was established in 13 by histologic evaluation of endoscopic biopsy or operative specimen and in 2 by radiologic imaging and the presence of eosinophilic ascites.RESULTS: All the patients had gastrointestinal symptoms and 12 (80 %) had hypereosinophilia (absolute eosinophil count 1 008 to 31 360/cm3). The most common symptoms were abdominal pain and diarrhea. Five of the 15 patients had a history of allergy. Seven patients had involvement of the mucosa, 2 of muscularis, and 6 of subserosa. One with a history of seafood allergy was successfully treated with an elimination diet. Another patient improved spontaneously after fasted for several days. The remaining 13 patients were treated with oral prednisolone, 10 to 40 mg/day initially,which was then tapered. The symptoms in all the patients subsided within two weeks. Eleven of the 15 patients were followed up for more than 12 months (12 to 104 months,mean 48.7), of whom 5 had relapses after discontinuing steroids (13 episodes). Two of these patients required longterm maintenance oral prednisolone (5 to 10 mg/day).CONCLUSION: Eosinophilic gastroenteritis is a rare condition of unclear etiology characterized by relapses and remissions. Short courses of corticosteroids are the mainstay of treatment, although some patients with relapsing disease require long-term low-dose steroids.

    We have gravimetrically calibrated the volumes dispensed by 1 mL syringes in the range between 1 µL and 100 µL using ultra-pure water. Protocols are based on series of consecutive difference measurements of masses in order to precisely compensate for evaporation, being the most important disturbing quantity. We determined expanded uncertainties of volume measurements for glass syringes of typically 0.2% (expansion factor 2) when dispensing volumes of 10 µL. For polypropylene syringes, selected with respect to the manufacturer, expanded uncertainties of 0.25% (expansion factor 2) were observed. Calibrated syringes were applied for measuring concentrations of blood cells in a flow cytometer demonstrating the capability to determine reference measurement values. Since the direct interaction of blood cells and syringe walls may lead to cell adhesion, glass syringes as well as (disposable) polypropylene syringes were calibrated.

    The peripheral blood mononuclear cell (PBMC) count is a routinely used and meaningful index for infection and blood diseases. PBMCs may be closely related to osteoclasts and include osteoclast precursors; we examined the association between the PBMC count and bone health. This research included 2806 community men aged ≥50 years who underwent full health examinations from October 2007 through December 2011 in four medical centers. The PBMC count was significantly high among subjects with "at least osteopenia" compared with controls. In analysis of covariance adjusted for potential confounders, the bone mineral density (BMD) value and T-score had a significant decreasing trend across the quartiles of PBMC count. In univariate analysis, the PBMC count had a strong association with "at least osteopenia" (odds ratio [OR] = 2.520, 95% confidence interval [CI]: 1.397-4.547). After adjustment for confounding factors (multivariate analysis) from Model 1 to 4, PBMC count remained as an independent risk factor for "at least osteopenia" (OR = 2.481, 95% CI: 1.176-5.236). Moreover, after adjusting for all confounding variables, participants had a significantly high OR in the body mass index (BMI) blood pressure (SBP) count is significantly associated with bone loss in elderly men and the exact mechanism requires further clarification.

    There is currently substantial interest in the therapeutic properties of probiotic microorganisms as recent research suggests that oral administration of specific bacterial strains may reduce inflammation and alter the nature of endogenous microflora in the gastrointestinal tract. Eosinophils are multifunctional tissue leukocytes, prominent among the resident cells of the gastrointestinal mucosa that promote local immunity. Recent studies with genetically altered mice indicate that eosinophils not only participate in maintaining gut homeostasis, but that the absence of eosinophils may have significant impact on the nature of the endogenous gut microflora and responses to gut pathogens, notably Clostridium difficile Furthermore, in human subjects, there is an intriguing relationship between eosinophils, allergic inflammation, and the nature of the lung microflora, notably a distinct association between eosinophil infiltration and detection of bacteria of the phylum Actinobacteria. Among topics for future research, it will be important to determine whether homeostatic mechanisms involve direct interactions between eosinophils and bacteria or whether they involve primarily eosinophil-mediated responses to cytokine signaling in the local microenvironment. Likewise, although is it clear that eosinophils can and do interact with bacteria in vivo, their ability to discern between pathogenic and probiotic species in various settings remains to be explored.

    Discovery and validation of genetic variants that influence disease severity in children with sickle cell anemia (SCA) could lead to early identification of high-risk patients, better screening strategies, and intervention with targeted and preventive therapy. We hypothesized that newly identified genetic risk factors for the general African American population could also impact laboratory biomarkers known to contribute to the clinical disease expression of SCA, including variants influencing the white blood cell count and the development of albuminuria and abnormal glomerular filtration rate. We first investigated candidate genetic polymorphisms in well-characterized SCA pediatric cohorts from three prospective NHLBI-supported clinical trials: HUSTLE, SWiTCH, and TWiTCH. We also performed whole exome sequencing to identify novel genetic variants, using both a discovery and a validation cohort. Among candidate genes, DARC rs2814778 polymorphism regulating Duffy antigen expression had a clear influence with significantly increased WBC and neutrophil counts, but did not affect the maximum tolerated dose of hydroxyurea therapy. The APOL1 G1 polymorphism, an identified risk factor for non-diabetic renal disease, was associated with albuminuria. Whole exome sequencing discovered several novel variants that maintained significance in the validation cohorts, including ZFHX4 polymorphisms affecting both the leukocyte and neutrophil counts, as well as AGGF1, CYP4B1, CUBN, TOR2A, PKD1L2, and CD163 variants affecting the glomerular filtration rate. The identification of robust, reliable, and reproducible genetic markers for disease severity in SCA remains elusive, but new genetic variants provide avenues for further validation and investigation.

    Full Text Available Abstract Background Diligent and correct laboratory diagnosis and up-front identification of risk factors for progression to severe disease are the basis for optimal management of malaria. Methods Febrile children presenting to the Medical Research Unit at the Albert Schweitzer Hospital (HAS in Lambaréné, Gabon, were assessed for malaria. Giemsa-stained thick films for qualitative and quantitative diagnosis and enumeration of malaria pigment, or haemozoin (Hz-containing leukocytes (PCL were performed, and full blood counts (FBC were generated with a Cell Dyn 3000® instrument. Results Compared to standard light microscopy of Giemsa-stained thick films, diagnosis by platelet count only, by malaria pigment-containing monocytes (PCM only, or by pigment-containing granulocytes (PCN only yielded sensitivities/specificities of 92%/93%; 96%/96%; and 85%/96%, respectively. The platelet count was significantly lower in children with malaria compared to those without (p ® instrument detected significantly more patients with PCL (p Conclusion In the age group examined in the Lambaréné area, platelets are an excellent adjuvant tool to diagnose malaria. Pigment-containing leukocytes (PCL are more readily detected by automated scatter flow cytometry than by microscopy. Automated Hz detection by an instrument as used here is a reliable diagnostic tool and correlates with disease severity. However, clinical usefulness as a prognostic tool is limited due to an overlap of PCL numbers recorded in severe versus non-severe malaria. However, this is possibly because of the instrument detection algorithm was not geared towards this task, and data lost during processing; and thus adjusting the instrument's algorithm may allow to establish a meaningful cut-off value.

    Exposure to wood dust within the woodworking industry has been shown to cause a variety of respiratory disorders. The aim of this study was to investigate the cellular effects in bronchoalveolar lavage (BAL) fluid and peripheral blood from healthy individuals exposed to pinewood dust. Eleven healthy volunteers were exposed to pinewood dust for 1 h in a whole-body exposure chamber. BAL fluid and blood cells were differentially counted and the expression of activation, adhesion and subset markers on alveolar macrophages and T-lymphocytes was determined 2-6 weeks before and 20 h after the exposure. Following pinewood dust exposure, the total BAL fluid cell concentration increased from 81.4 (64.1-97.5) x 10(6) cells x L(-1) (median (interquartile range)) to 195.3 (154.6-341.2) x 10(6) cells x L(-1). The BAL fluid T-lymphocyte concentration increased from 3.8% (3.5-6.5%) to 7.6% (4.9-11.2%), and BAL fluid eosinophil concentration from 0.0% (0.0-0.2%) to 1.8% (0.6-3.5%). Inhalation of pinewood dust leads to the recruitment of inflammatory cells to the airways of healthy individuals. The increase in numbers of eosinophils, T-lymphocytes and mast cells, i.e. cells of crucial importance to airway inflammation, in the lungs may be related to the increased risk of developing respiratory disorders among woodworkers.

    This study aimed to identify the relationship between fractional exhaled nitric oxide (FeNO) level and potential factors in non-asthmatic children from Shanghai, China. From March to April 2012, the school-aged children fulfilling the inclusion criteria were recruited. The FeNO levels of non-asthmatic children were detected by the Nano Coulomb nitric oxide analyzer. Questionnaires were recorded, including personal data, family illness history and daily habits. In addition, not only the number of leukocytes and eosinophils but also the level of hemoglobin in peripheral blood, were measured via the automated blood cell analyzer. All data were statistically analyzed with SPSS version 17.0 software and the correlation of these potential factors with FeNO level was calculated via Kendall's rank correlation. A total of 132 healthy children (aging 6-13 years) were enrolled in Minhang District, Shanghai, China. The mean value of FeNO level was 15.05 ppb. The correlation analyses revealed that age (R=0.190, p=0.029) and eosinophil number (R=0.575, p=0.000) were significantly and positively correlated with FeNO levels. The FeNO levels of individuals aged 10-13 years was significantly higher than those of the individuals aged 6-9 years (22.65 ± 18.82 ppb vs. 15.28 ± 9.78 ppb, p<0.05). However, other potential factors were not significantly correlated with FeNO level. The FeNO levels in healthy school-aged children may reflect airway eosinophilic inflammation levels, and was affected by eosinophil count and age significantly.

    Full Text Available Eosinophilic gastroenteritis is a rare gastrointestinal (GI disorder characterized by nonspecific GI symptoms, peripheral eosinophilia, and eosinophilic infiltration of the intestinal wall. The disorder is classified into mucosal, muscular, and sub-serosal types, depending on the clinical picture and the depth of eosinophilic infiltration within the GI wall. Sub-serosal disease, which is complicated by ascites, usually results in the most severe clinical form of eosinophilic gastroenteritis and requires early corticosteroid therapy. In such cases, a favorable outcome can be achieved after a short course of corticosteroids. We present the case of a 28-year-old female with diffuse abdominal pain and distention for 2 weeks. Her physical examination was significant for moderate ascites. Initial work-up demonstrated severe peripheral blood eosinophilia, normal liver function tests, and elevated serum immunoglobulin E (IgE. Upper endoscopy, colonoscopy showed a thickening of the stomach and colon, and biopsies showed marked eosinophilic infiltration of the mucosa. Ascitic fluid analysis showed significant eosinophilia. Subsequent treatment with oral prednisone resulted in the normalization of laboratory and radiologic abnormalities 45 days after the start of the treatment. Despite its rarity, eosinophilic gastroenteritis needs to be recognized by the clinician because the disease is treatable, and timely diagnosis and initiation of treatment could be of major importance.

    Full Text Available A case of a canine oral eosinophilic granuloma in a 14-year-old female crossbred is described. The dog was presented with a history of ptyalism, halitosis, local pain, decreased appetite, and blood staining noted on food and water bowls. Clinical, hematologic, and biochemical examinations, abdominal ultrasonography, and 3-view chest radiographs were performed, and no metastases were found. Histopathologic examination of two 6 mm punch biopsies from the oral lesion revealed the presence of eosinophilic granulomatous lesions in the submucosa. After treatment with corticosteroids and wide spectrum antibiotics no significant changes in clinical signs and lesion size were observed. Electrochemotherapy (ECT, a novel tumor treatment routinely used for cutaneous and subcutaneous tumors in human patients in the European Union since 2006, was used to treat the eosinophilic granuloma. The procedure was performed under general anesthesia, followed by intravenous administration of bleomycin. Six weeks after treatment a complete response with disappearance of the mass and improvement of clinical signs were observed.

    A rotary blood pump fuzzy logic flow controller without flow sensors was developed and tested in vitro. The controller, implemented in LabView, was set to maintain a flow set point in the presence of external pressure disturbances. Flow was estimated as a function of measured pump's delta P and speed, using a steady-state, nonlinear approximation. The fuzzy controller used the pump's flow estimate and delta P as feedback variables. The defuzzified control output manipulated the pump speed. Membership functions included flow error, delta P, and pump speed. Experimental runs in a mock loop (water/glycerin 3.5 cPs, 37 degrees C), using the estimated flow, were compared with those using a Transonic flow meter for nine conditions of flow and delta P (4 to 6 L/min, 150 to 350 mm Hg). Pressure disturbances generated by a servo pinch valve ranged from +/-23 to +/-47 mm Hg. Results indicated that the fuzzy controller ably regulated the flow set point to within +/-10% of the baseline even under large swings in pressure. There was no difference in controller performance between the ultrasonic flow measurement and the estimated flow calculation scenarios. These tests demonstrated that the fuzzy controller is capable of rejecting disturbances and regulating flow to acceptable limits while using a flow estimate.

    Full Text Available Eosinophilic colitis is a rare form of primary eosinophilic gastrointestinal disease that is poorly understood. Neonates and young adults are more frequently affected. Clinical presentation is highly variable depending on the depth of inflammatory response (mucosal, transmural, or serosal. The pathophysiology of eosinophilic colitis is unclear but is suspected to be related to a hypersensitivity reaction given its correlation with other atopic disorders and clinical response to corticosteroid therapy. Diagnosis is that of exclusion and differential diagnoses are many because colonic tissue eosinophilia may occur with other colitides (parasitic, drug-induced, inflammatory bowel disease, and various connective tissue disorders. Similar to other eosinophilic gastrointestinal disorders, steroid-based therapy and diet modification achieve very good and durable responses. In this paper, we present our experience with this rare pathology. Five patients (3 pediatric and 2 adults presented with diarrhea and hematochezia. Mean age at presentation was 26 years. Mean duration of symptoms before pathologic diagnosis was 8 months. Mean eosinophil count per patient was 31 per high-power field. The pediatric patients responded very well to dietary modifications, with no recurrences. The adult patients were treated with steroids and did not respond. Overall mean followup was 22 (range, 2–48 months.

    Few studies have assessed the relationship between a subnormal inflammatory status and metabolic syndrome (MS). We therefore designed a cross-sectional and 5-year cohort study to evaluate how a subnormal peripheral blood leukocyte count is related to MS. Participants were recruited from Tianjin Medical University General Hospital-Health Management Centre. Both a baseline cross-sectional (n = 46,179) and a prospective assessment (n = 13,061) were performed. Participants without a history of MS were followed up for 5 years. Leukocyte counts and MS components were assessed at baseline and yearly during the follow-up. Adjusted logistic and Cox proportional hazards regression models were used to assess relationships between the categories of leukocyte counts and MS. The subnormal leukocyte counts group (1,100–3,900 cells/mm3) had the lowest prevalence and incidence of MS. The odds ratio and hazard ratio (95% confidence interval) of the highest leukocyte counts were 1.98 (1.57–2.49) and 1.50 (1.22–1.84) (both P for trend <0.0001), respectively, when compared to the subnormal leukocyte counts group after adjusting for potential confounders. This study has shown that subnormal leukocyte counts are independently related to the lowest prevalence and incidence of MS. The findings suggest that it is necessary to restudy and discuss the clinical or preventive value of subnormal leukocyte counts. PMID:24876672

    Full Text Available White blood cell (WBC count has been associated with diabetic risk, but whether the correlation is independent of other risk factors has hardly been studied. Moreover, very few such studies with large sample sizes have been conducted in Chinese. Therefore, we investigated the relationship between WBC count and glucose metabolism in china. We also examined the relevant variables of WBC count. A total of 9,697 subjects (mean age, 58.0 ± 9.1 years were recruited. The subjects were classified into four groups, including subjects with normal glucose tolerance, isolated impaired fasting glucose, impaired glucose tolerance and type 2 diabetes mellitus (T2DM. We found that WBC count increased as glucose metabolism disorders exacerbated. WBC count was also positively correlated with waist hip ratio, body mass index, smoking, triglycerides, glycosylated haemoglobin A1c (HbA1c and 2-h postprandial glucose. In addition, high density lipoprotein and the female gender were inversely correlated with WBC count. In patients with previously diagnosed T2DM, the course of T2DM was not correlated with WBC count. Our findings indicate that elevated WBC count is independently associated with worsening of glucose metabolism in middle-aged and elderly Chinese. In addition, loss of weight, smoking cessation, lipid-modifying therapies, and control of postprandial plasma glucose and HbA1c may ameliorate the chronic low-grade inflammation.

    Blood bank regulatory agencies including the Drug and Cosmetics Act (DCA) of India do not mandate a predonation platelet count in whole blood donation. Mandating such practice will definitely optimize the quality of random donor platelets (RDP) in terms of platelet yield and patient therapeutic benefit. We observed poor platelet yield in RDP concentrates prepared at our center with a significant number not meeting the DCA guideline of ≥ 4.5 × 10(10) per bag processed from 450 ml of whole blood. Therefore we planned this study to evaluate the pre-donation hematological values in our blood donor population and effect of these values on the quality of platelet concentrates. The prospective study included 221 blood donors eligible for donating 450 ml of whole blood (WB). Following the departmental standard operating procedure (SOP) RDPs were prepared using the 'Top & Bottom' quadruple bag system and automated component extractor. Quality of RDP was assessed as per departmental protocol. All results were recorded and subsequently transcribed to SPSS working sheet. A significant (pblood counts has been observed after WB donation. Mean donor Hb and platelets reduced by 0.72 g/dl and 22.1 × 10(6)/ml respectively. Quality of RDPs in terms of platelet yield was significantly better (pcount was >200 × 10(6)/ml. Although platelet yield significantly correlated with the donor platelet count however quality of RDPs in terms of red cell contamination showed no correlation with the donor hematocrit. Platelet yield in random donor platelets is a concern in Eastern India. A platelet yield of 4.5 × 10(10) per bag as mandated by the DCA of India was only achieved when the donor platelet count was >200 × 10(6)/ml. Posttransfusion platelet recovery (PPR) was unsatisfactory in the transfused patient. Introduction of pre-donation platelet count in whole blood donation will maximize donor safety and optimize patient platelet transfusion management.

    A 38-year-old woman was referred to our institution due to epigastralgia. She presented with obstructive jaundice and eosinophilia. Endoscopic retrograde cholangiopancreatography showed diffuse narrowing from the distal common bile duct to the bifurcation of the hepatic ducts. An endoscopic plastic biliary stent was inserted; the specimen obtained from the common bile duct wall revealed dense infiltration by eosinophils.Treatment was started with prednisolone 60 mg daily.The patient's biliary stenosis and eosinophilia gradually improved. Eosinophilic infiltration in the lungs or stomach is relatively common, but it is rare in the common bile dud. Most of the reported cases of eosinophilic cholangitis presented with eosinophilia; our patient's eosinophil count was over 1000/mm3. Since our patient had allergies to pollen and house dust, a relationship between the allergies and the eosinophilic cholangitis was suspected, but no cause was identified.

    Full Text Available Eosinophilic fasciitis is clinically characterized by symmetrical scleroderma-like indurations of the skin with pain. The histological features are fascial inflammation with lymphocytes and eosinophils as well as thickened and fibrotic fascia. Lymphocytic infiltration and degeneration of the underlying muscle are rarely observed. We report a 69-year-old Japanese woman who presented with multiple areas of glossy induration and painful peau d'orange-like lesions on the chest and four extremities. T2-weighted magnetic resonance imaging showed significant hyperintense thickening of the fascia of the lower extremities. Histopathological examination of a biopsy specimen from the induration showed marked fibrinoid degeneration of the fascia and the neighboring muscle with mixed cellular infiltration of lymphocytes and eosinophils. The predominant CD8+ lymphocytic infiltrates were observed by immunohistological study. A diagnosis of eosinophilic fasciitis with myositis was made. Oral administration of prednisolone and discontinuation of exercise significantly improved the lesions and pain.

    Full Text Available AIMS AND OBJECTIVES: To observe the change in haemoglobin level and leukocyte counts in the cord blood of neonates born of hypertensive mothers by comparing it with the haemoglobin level and leukocyte counts of cord blood of neonates born of healthy mothers. MATERIALS AND METHODS: A Prospective observational study was carried out among thirty newborns of hypertensive mothers and thirty apparently healthy newborns of normotensive mothers in, West Tripura. Haemoglobin level was estimated by Sahli’s method and total Leukocyte count (TLC was done using Improved Neubauer’s Counting chamber. Absolute counts were obtained by doing Differential Leukocyte Count (DLC and the value obtained from TLC. For DLC, slides were stained with Leishman’s stain. Statistical analysis was carried out using t-test for the comparison of differences of the means by SPSS 15.0. RESULTS: Haemoglobin level was found to be significantly higher in the study group as compared to control group. Leukopenia, neutropenia, lymphopenia and anaemia were found in 10%, 3.3%, 13.3% and 23.3% subjects respectively in the study group. Leukopenia, lymphopenia and anaemia were also found in 6.6%, 10% and 56.6% subjects respectively in the control group. CONCLUSION: A significant haematological changes occur in the newborns of hypertensive mothers and further research need to be carried out to find the relation between hypertensive disorders and changes in haematological parameters of the newborns.

    Radioactive iodine (RAI) is considered to be related with hematologic changes. This study aimed to evaluate influence of the first RAI ablation on peripheral complete blood count (CBC) in patients with differentiated thyroid cancer (DTC).Data of CBC at baseline and 6 months after RAI were obtained in 385 patients with DTC with approximately 3700 MBq I (ranging 2220-7585 MBq). Further comparison was done in 196 patients with 1-month postablation data available. Routine blood examinations were performed to determine impact of RAI on white blood cell (WBC), red blood cell (RBC), hemoglobin, platelet, neutrophil, lymphocyte, and monocyte in both sexes. Continuous variables were compared by paired t tests and independent samples t test, and categorical variables were compared by chi-square analysis. Data with repeated measurements were analyzed by analysis of variance.The first RAI after thyroidectomy was associated with mild, yet significant declines in WBC, platelet, and lymphocyte, which persisted for 6 months. One month after RAI, significant declines were found in all CBC, including RBC and hemoglobin (all P < 0.05). While CBC partly recovered 6 months after RAI, this follow-up CBC still demonstrated significant declines in WBC, platelet, and lymphocyte (all P < 0.05) without gender differences. Significant rises in RBC and hemoglobin in males and females were found. The decline of platelet in females was more obvious than in males at 3700 to 4440 MBq of RAI. On the contrary, the rises of RBC and hemoglobin in males were higher than in females. There were no significant complications during the follow-up.WBC and platelet decreased obviously 1 month after RAI. While they partly recovered 6 months after RAI, they were still lower than the baseline. However, RBC and hemoglobin transiently decreased at 1 month and then increased to levels even higher than baseline 6 months later. At 3700 to 4440 MBq of RAI, the decline of platelet in females was more obvious

    Background: Airway smooth muscle (ASM) remodeling is an important component of the structural changes to airways seen in asthma. Eosinophils are the prominent inflammatory cells in asthma, and there is some evidence that they contribute to ASM remodeling via released mediators and direct contact through integrin–ligand interactions. Eosinophils express several types of outer membrane integrin, which are responsible for cell–cell and cell–extracellular matrix interactions. In our previous study we demonstrated that asthmatic eosinophils show increased adhesion to ASM cells and it may be important factor contributing to ASM remodeling in asthma. According to these findings, in the present study we investigated the effects of suppression of eosinophil integrin on eosinophil-induced ASM remodeling in asthma. Materials and Methods: Individual combined cell cultures of immortalized human ASM cells and eosinophils from peripheral blood of 22 asthmatic patients and 17 healthy controls were prepared. Eosinophil adhesion was evaluated using eosinophil peroxidase activity assay. Genes expression levels in ASM cells and eosinophils were measured using quantitative real-time PCR. ASM cell proliferation was measured using alamarBlue® solution. Eosinophil integrins were blocked by incubating with Arg-Gly-Asp-Ser peptide. Results: Eosinophils from the asthma group showed increased outer membrane α4β1 and αMβ2 integrin expression, increased adhesion to ASM cells, and overexpression of TGF-β1 compared with eosinophils from the healthy control group. Blockade of eosinophil RGD-binding integrins by Arg-Gly-Asp-Ser peptide significantly reduced adhesion of eosinophils to ASM cells in both groups. Integrin-blocking decreased the effects of eosinophils on TGF-β1, WNT-5a, and extracellular matrix protein gene expression in ASM cells and ASM cell proliferation in both groups. These effects were more pronounced in the asthma group compared with the control group. Conclusion

    Eosinophils are leukocytes that are released into the peripheral blood in a phenotypically mature state and are capable of being recruited into tissues in response to appropriate stimuli. Eosinophils, traditionally considered cytotoxic effector cells, are leukocytes recruited into the airways of asthma patients where they are believed to contribute to the development of many features of the disease. This perception, however, has been challenged by recent findings suggesting that eosinophils have also immunomodulatory functions and may be involved in tissue homeostasis and wound healing. Here we describe a transcriptome-based approach–in a limited number of patients and controls—to investigate the activation state of circulating human eosinophils isolated by flow cytometry. We provide an overview of the global expression pattern in eosinophils in various relevant conditions, e.g., eosinophilic asthma, hypereosinophilic dermatological diseases, parasitosis and pulmonary aspergillosis. Compared to healthy subjects, circulating eosinophils isolated from asthma patients differed in their gene expression profile which is marked by downregulation of transcripts involved in antigen presentation, pathogen recognition and mucosal innate immunity, whereas up-regulated genes were involved in response to non-specific stimulation, wounding and maintenance of homeostasis. Eosinophils from other hypereosinophilic disorders displayed a very similar transcriptional profile. Taken together, these observations seem to indicate that eosinophils exhibit non-specific immunomodulatory functions important for tissue repair and homeostasis and suggest new roles for these cells in asthma immunobiology.

    Myelodysplastic syndrome (MDS) was diagnosed in a 64-year-old man. Three months later, he presented with right-sided visual loss. A diagnosis of optic neuritis caused by both ischemic and non-ischemic changes was established. Concurrently, prominent eosinophilia was seen in both the peripheral blood and bone marrow. A partial improvement of visual loss was obtained concomitant with a rapid decrease of the eosinophils after treatment with corticosteroids. Optic neuritis related to MDS is a rare condition and its etiology has not yet been identified. We herein report a case of optic neuritis associated with MDS and accompanied by an eosinophilic crisis.

    Common marmosets (Callithrix jacchus) are frequently used as translational animal models for human diseases. However, a comparative study of cytological and histochemical detection methods as well as morphometric and ultrastructural characterization of neutrophils and eosinophils in this species is lacking. Blood samples of house dust mite sensitized and allergen challenged as well as lipopolysaccharide (LPS) challenged marmosets were analyzed with different cytological and histological staining methods. Furthermore, cell size and number of nuclear segments were compared between neutrophils and eosinophils. Electron microscopy was performed to characterize the ultrastructure of granulocytes. Of all applied cytological stains, three allowed differentiation of eosinophils and neutrophils and, thus, reliable quantification in blood smears: May-Grünwald-Giemsa stain, Congo Red and Naphthol AS-D Chloroacetate-Esterase. For histology, Hematoxylin-Eosin (H&E) could not demonstrate clear differences, whereas Sirius Red, Congo Red, and Naphthol AS-D Chloroacetate Esterase showed capable results for identification of eosinophils or neutrophils in lung tissue. Morphometry revealed that marmoset neutrophils have more nuclear segments and are slightly larger than eosinophils. Ultrastructurally, eosinophils presented with large homogeneous electron-dense granules without crystalloid cores, while neutrophils were characterized by heterogeneous granules of different size and density. Additionally, sombrero-like vesicles were detected in tissue eosinophils of atopic marmosets, indicative for hypersensitivity-related piecemeal degranulation. In conclusion, we provide a detailed overview of marmoset eosinophils and neutrophils, important for phenotypic characterization of marmoset models for human airway diseases.

    1. The oxygen consumption of blood of normal individuals, when the hemoglobin is saturated with oxygen, is practically zero within the limits of experimental error of the microspirometer used. 2. The oxygen consumed in a microspirometer by the blood of patients with chronic myelogenous leucemia with a high white blood cell count, and of one with leucocytosis from sepsis, was proportional to the number of adult polymorphonuclear neutrophils in the blood. 3. No correlation could be made between the rate of oxygen absorption and the total number of white blood cells in the blood, or the total number of immature cells, or the number of red blood cells, or the amount of oxyhemoglobin. 4. The blood of patients with chronic myelogenous leucemia continued to use oxygen in the microspirometer longer than that of normal individuals, and the hemoglobin, in the leucemic bloods, became desaturated even though exposed to air. 5. In blood in which the bulk. of the cells were immature and the mature cells few, the oxygen consumption was lower than in blood in which the mature cells predominated. The rate of oxygen consumption of the immature cells was relatively low as compared to the mature. 6. The slower rate of oxygen absorption by the immature leucocytes in chronic myelogenous leucemia as compared to the mature cells, places them, in accord with Warburg's reports, in the class of the malignant tissues in this respect rather than in the group of young or embryonic cells.

    Full Text Available This study was designed to investigate the possible adverse effects that may be induced by once-daily therapeutic doses of either glucosamine sulfate or glucosamine/chondroitin sulfate administered orally to rats for 30 days on blood cells (RBCs, WBCs and platelets counts. Forty three white healthy adult Albino rats of both sexes were selected randomly for this study. They were divided into three groups (І, ІІ, ІІІ. Group І received 0.05 ml distilled water, group ІІ received once daily therapeutic dose of glucosamine sulphate and group ІІІ received once daily therapeutic dose of glucosamine sulphate/chondroitin sulphate orally. The treatment period was for 30 days. At day 31, the animals were subjected to light ether anaesthesia and blood was withdrawn from the eye by retro-orbital puncture for the estimation of blood cells (RBCs, WBCs and platelets count. Treatment with single daily therapeutic dose of either GS alone or GS/CS for 30 days on blood cells count in rats produced a non significant change in RBCs counts compared to control and to each other. There were no statistically significant differences in total WBCs count at day 31 in animals administered once daily therapeutic dose of either GS or GS/CS orally compared to control group. In contrast, there was a statistically significant elevation in total WBCs count in GS/CS- treated rats compared to that in the GS-treated rats. The results of this study also showed that there was statistically significant decrease in neutrophils percentage in both drug treatment groups compared to control group.

    Epigenome-wide association studies of prenatal exposure to different environmental factors are becoming increasingly common. These studies are usually performed in umbilical cord blood. Since blood comprises multiple cell types with specific DNA methylation patterns, confounding caused by cellular heterogeneity is a major concern. This can be adjusted for using reference data consisting of DNA methylation signatures in cell types isolated from blood. However, the most commonly used reference data set is based on blood samples from adult males and is not representative of the cell type composition in neonatal cord blood. The aim of this study was to generate a reference data set from cord blood to enable correct adjustment of the cell type composition in samples collected at birth. The purity of the isolated cell types was very high for all samples (>97.1%), and clustering analyses showed distinct grouping of the cell types according to hematopoietic lineage. We explored whether this cord blood and the adult peripheral blood reference data sets impact the estimation of cell type composition in cord blood samples from an independent birth cohort (MoBa, n = 1092). This revealed significant differences for all cell types. Importantly, comparison of the cell type estimates against matched cell counts both in the cord blood reference samples (n = 11) and in another independent birth cohort (Generation R, n = 195), demonstrated moderate to high correlation of the data. This is the first cord blood reference data set with a comprehensive examination of the downstream application of the data through validation of estimated cell types against matched cell counts.

    Full Text Available Background: Most lantern mantles contain low levels of radioactive thorium. Although radioactive lantern mantles present a minimal radiation health hazard, it is generally believed when inhaled or ingested, it can be dangerous. The purpose of this study was to assess the effect of short term exposure to radioactive lantern mantle on serum cortisol level and blood count.Materials and Methods: This experimental study was conducted in 2007-2009 in the school of medicine of Rafsanjan University of Medical Sciences. Twenty eight rats were divided randomly into two groups of 14 animals each. The first group was exposed to 600 mg burned radioactive lantern mantle powder (activity of 800Bq for 24 hours and inhaled radon released from mantles. The second group was exposed to non-radioactive lantern mantle powder at the same interval. Paired t-test was used to evaluate the difference in the means of cortisol and blood cell count in both groups. P<0.05 was considered as the significance level.Results: Short term exposure of animals to radioactive lantern mantle powder led to a statistically significant decreased cortisol level, while no statistically significant decrease was found in animals that were exposed to non-radioactive mantle powder. Furthermore, a significant reduction was shown in post-exposure counts of WBC in the case group.Conclusions: Despite alteration of serum cortisol level, this study could not show stimulatory effects in some blood counts

    A 3-year-old, male, domestic shorthaired cat was presented with a 3-day history of anorexia and depression. The cat was moderately dehydrated, had pale, slightly icteric, mucous membranes, oral ulcerations, and mild hepatosplenomegaly. A feline leukemia virus (FeLV) antigen test was positive. CBC results obtained at initial presentation included severe normocytic, normochromic, nonregenerative anemia, severe thrombocytopenia, and marked leukocytosis (>100,000/microL) with 77% eosinophils. After 15 days of treatment with prednisone and doxycycline, the cat had persistent severe nonregenerative anemia (HCT 3.4%), thrombocytopenia (28,000/microL), and extreme eosinophilia (total eosinophils, 123.1 x 10(3)/microL; segmented 103.0 x 10(3)/microL; immature 20.1 X 10(3)/microL). Cytologic examination of aspirates from bone marrow, liver, lymph nodes, and spleen revealed a predominance of mature and immature eosinophils, many with dysplastic changes. The M:E ratio was 96.4. On histopathologic examination, multiple organs were infiltrated by eosinophilic granulocytes. Neoplastic cells in blood and bone marrow stained positive for alkaline phosphatase and were negative for myeloperoxidase, chloroacetate esterase, and alpha-naphthyl acetate esterase. On flow cytometric analysis of peripheral blood, the neoplastic cells were positive for CD11b and CD14. These findings were consistent with chronic eosinophilic leukemia. To our knowledge, this is the first report of chronic eosinophilic leukemia in a cat associated with naturally acquired FeLV infection, in which flow cytometry was used to characterize the neoplastic cells.

    The metabolic syndrome is highly prevalent in patients with schizophrenia, and is associated with a state of chronic, low-grade inflammation. Schizophrenia is also associated with increased inflammation, including aberrant blood levels of pro-inflammatory cytokines and high-sensitivity C-reactive protein (hsCRP). The purpose of this study is to investigate the relationship between total and differential white blood cell (WBC) counts, hsCRP, and the metabolic syndrome in patients with schizophrenia and related non-affective psychoses. Fifty-nine inpatients and outpatients age 18-70 with non-affective psychotic disorders and 22 controls participated in this cross-sectional study. Subjects had a fasting blood draw between 8 and 9 am for glucose, lipids, total and differential WBC counts, and hsCRP. Vital signs and anthropometric measures were obtained. Patients with non-affective psychosis and the metabolic syndrome had significantly higher total WBC counts, monocytes, and hsCRP levels than patients without the metabolic syndrome (p≤0.04 for each). In binary logistic regression analyses, after controlling for potential confounding effects of age, race, sex, age at first hospitalization for psychosis, parental history of diabetes, smoking, and psychotropic medications, total WBC count, monocytes, and hsCRP were significant predictors of metabolic syndrome in patients (p≤0.04 for each). hsCRP was also a significant predictor of increased waist circumference and triglycerides in patients (p≤0.05 for each). Our findings suggest that measurement of total and differential WBC counts and hsCRP blood levels may be germane to the clinical care of patients with schizophrenia and related disorders, and support an association between inflammation and metabolic disturbance in these patients.

    Inflammatory processes are implicated in the development and progression of age-related macular degeneration (AMD). However, there are limited data on longitudinal associations between systemic markers of inflammation and AMD. The authors examined the prospective relation between the circulating white blood cell (WBC) count and early and late AMD in a population-based cohort of 3,654 participants, aged 49-97 years, in the Blue Mountains region, Australia. The main outcome of interest was the 10-year incidence of early and late AMD among individuals free from corresponding disease at the baseline (1992-1994). An elevated baseline WBC count was associated with early AMD incidence, independent of smoking and other major confounders. The multivariable relative risk comparing tertile 3 of WBC count (>6.7 x 10(9) cells/liter) with tertile 1 (count and early AMD was present consistently in analyses of different early AMD lesions, including incident pigmentary abnormalities and soft indistinct/reticular drusen. Moreover, this association persisted in subgroup analyses by gender and smoking. An elevated WBC count at baseline was not consistently associated with late AMD incidence. This study provides population-based evidence supporting a longitudinal association between the circulating WBC count, a widely available marker of inflammation, and incidence of early AMD.

    Adipose tissue (AT) inflammation during obesity is mediated by immune cells and closely correlates with systemic insulin resistance. In lean AT, eosinophils are present in low but significant numbers and capable of promoting alternative macrophage activation in an IL-4/IL-13-dependent manner. In WT mice, obesity causes the proportion of AT eosinophils to decline, concomitant with inflammation and classical activation of AT macrophages. In this study, we show that CCR2 deficiency leads to increased eosinophil accumulation in AT. Furthermore, in contrast to WT mice, the increase in eosinophils in CCR2(-/-) AT is sustained and even amplified during obesity. Interestingly, a significant portion of eosinophils is found in CLSs in AT of obese CCR2(-/-) mice, which is the first time eosinophils have been shown to localize to these inflammatory hot spots. CCR2(-/-) bone marrow precursors displayed increased expression of various key eosinophil genes during in vitro differentiation to eosinophils, suggesting a potentially altered eosinophil phenotype in the absence of CCR2. In addition, the proportion of eosinophils in AT positively correlated with local expression of Il5, a potent eosinophil stimulator. The increase in eosinophils in CCR2(-/-) mice was detected in all white fat pads analyzed and in the peritoneal cavity but not in bone marrow, blood, spleen, or liver. In AT of CCR2(-/-) mice, an increased eosinophil number positively correlated with M2-like macrophages, expression of the Treg marker Foxp3, and type 2 cytokines, Il4, Il5, and Il13. This is the first study to link CCR2 function with regulation of AT eosinophil accumulation.

    Objective: To investigate the relation between eosinophilic materials and amyloid P (AP) component in adenomatoid odontogenic tumor (AOT). Methods: The expression of amyloid proteins and basement membrane proteins, including type Ⅳ collagen, laminin and heparin sulfate proteoglycan (HSPG), in AOT were analyzed by immunohistochemical method. Results:Most eosinophilic droplets among tumor cells and some epithelial cells showed positive stain for AP component.The immunoreactions of type Ⅳ collagen and laminin were only found in blood vessels of this tumor. The tumor cells and eosinophilic materials in duct-like structures were constantly unstained for both amyloid and basement membrane proteins. Present results suggest that the nature and composition of eosinophilic droplets may differ from the eosinophilic layer in ductlike structures. This study first demonstrated that the amyloid-like deposition in AOT is associated with AP component by immunohistochemical method. It supported that AP component may be epithelial origin since the AP immunolocalization was found in tumor cells.

    It remains controversial whether adjuvant therapy should be delivered to pathological T3N0M0 rectal cancer without neoadjuvant chemoradiotherapy. Thus identification of patients at high risk is of particular importance. Herein, we aimed to evaluate whether the absolute peripheral blood monocyte count can stratify the pathological T3N0M0M0 rectal cancer patients in survival. A total of 270 pathological T3N0M0 rectal cancer patients with total mesorectal excision-principle radical resection were included. The optimal cut-off value of preoperative monocyte count was determined by receiver operating characteristic curve analysis. Overall survival and disease-free survival between low- and high-monocyte were estimated by Kaplan-Meier method and Cox regression model. The optimal cut-off value for monocyte count was 595 mm(3). In univariate analysis, patients with monocyte counts higher than 595/mm(3) had significantly inferior 5-year overall survival (79.2 vs 94.2 %, P = 0.006) and disease-free survival (67.8 vs 86.0 %, P count remained to be associated with poor overall survival (HR = 2.55, 95 % CI 1.27-5.10; P = 0.008) and disease-free survival (HR = 2.63, 95 % CI 1.48-4.69; P = 0.001). Additionally, the significant association of monocyte count with disease-free survival was hardly influenced in the subgroup analysis, whereas this correlation was restricted to the males and patients with normal carcinoembryonic antigen (CEA) level (count is independently predictive of worse survival of pathological T3N0M0 rectal cancer patients without neoadjuvant chemoradiotherapy. Postoperative adjuvant therapy might be considered for patients with high-monocyte count.

  4. GM-CSF Differentially Regulates Eosinophil and Neutrophil Adhesive Interactions with Vascular Endothelium in Vivo

    Full Text Available Allergic airway inflammation is characterized by elaboration of cytokines and chemokines leading to recruitment of inflammatory leukocytes, predominantly eosinophils, to the airways. Granulocyte macrophage colony stimulating factor (GM-CSF is generated in the lungs of human subjects with asthma in response to allergen challenge and is necessary for the development of allergen-induced bronchial eosinophilia in mice. The effect of GM-CSF on human eosinophil and neutrophil interactions with the vascular endothelium under conditions of blood flow was investigated in post-capillary venules of the rabbit mesentery by intravital microscopy.While GM-CSF significantly reduced the rolling fraction of neutrophils in vivo and induced consistent shedding of neutrophil L-selectin in vitro, its effect on eosinophil rolling was variable. Eosinophils from 57% of the donors demonstrated inhibition of rolling, while eosinophils from the remaining 43% of donors demonstrated no inhibition or increased rolling. The variable effect of GM-CSF on inhibition of eosinophil rolling was associated with variable shedding of L-selectin in vitro. In contrast to the differential effect of GM-CSF on neutrophils versus eosinophils, stimulation with phorbol myristate acetate demonstrated a similar degree of inhibition of rolling and L-selectin shedding by neutrophils and eosinophils suggesting that there was no defect in L-selectin shedding in the eosinophil donors who did not respond to GM-CSF. Overall, these studies demonstrate that GM-CSF consistently inhibits interaction of neutrophils with endothelium in vivo, whereas its effect on eosinophil-endothelial interactions is variable. GM-CSF may thus be one factor accounting for the varying percentage of eosinophils and neutrophils recruited to sites of allergic inflammation in different individuals.

  5. Hematopoietic Processes in Eosinophilic Asthma.

    2017-01-24

    Airway eosinophilia is a hallmark of allergic asthma and understanding mechanisms that promote increases in lung eosinophil numbers is important for effective pharmaco-therapeutic development. It has become evident that expansion of hemopoietic compartments in the bone marrow promotes differentiation and trafficking of mature eosinophils to the airways. Hematopoietic progenitor cells egress the bone marrow and home to the lungs, where in-situ differentiative processes within the tissue provide an ongoing source of pro-inflammatory cells. In addition, hematopoietic progenitor cells in the airways can respond to locally-derived alarmins, to produce a panoply of cytokines thereby themselves acting as effector pro-inflammatory cells that potentiate type 2 responses in eosinophilic asthma. In this review, we will provide evidence for these findings and discuss novel targets for modulating eosinophilopoietic processes, migration and effector function of precursor cells.

    Eosinophil migration into the gut and the release of granular mediators plays a critical role in the pathogenesis of inflammatory bowel diseases, including ulcerative colitis. We recently demonstrated that eosinophil migration into the lung requires cell surface expression of the sialomucin CD34 on mast cells and eosinophils in an asthma model. Based on these findings, we investigated a similar role for CD34 in the migration of eosinophils and other inflammatory cells into the colon as well as explored the effects of CD34 ablation on disease development in a dextran sulfate sodium-induced model of ulcerative colitis. Our findings demonstrate decreased disease severity in dextran sulfate sodium-treated Cd34(-/-) mice, as assessed by weight loss, diarrhea, bleeding, colon shortening and tissue pathology, compared with wild-type controls. CD34 was predominantly expressed on eosinophils within inflamed colon tissues, and Cd34(-/-) animals exhibited drastically reduced colon eosinophil infiltration. Using chimeric animals, we demonstrated that decreased disease pathology resulted from loss of CD34 from bone marrow-derived cells and that eosinophilia in Cd34(-/-)IL5(Tg) animals was sufficient to overcome protection from disease. In addition, we demonstrated a decrease in peripheral blood eosinophil numbers following dextran sulfate sodium treatment. These findings demonstrate that CD34 was expressed on colon-infiltrating eosinophils and played a role in eosinophil migration. Further, our findings suggest CD34 is required for efficient eosinophil migration, but not proliferation or expansion, in the development of ulcerative colitis.

    Full Text Available Background: Radiotherapy is frequently used in treatment approaches of pelvic malignancies. Nevertheless, it has some known systemic effects on blood cells and the immune system that possibly results in their susceptibility to infection. Probiotics are live microbial food ingredients that provide a health advantage to the consumer. Honey has prebiotic properties. The aim of this clinical trial was to investigate probable effects of probiotic or probiotics plus honey on blood cell counts and serum IgA levels in patients receiving pelvic radiotherapy. Materials and Methods: Sixty-seven adult patients with pelvic cancer were enrolled. Patients were randomized to receive either: (1 Probiotic capsules (including: Lactobacillus casei, Lactobacillus acidophilus, Lactobacillus rhamnosus, Lactobacillus bulgaricus, Bifidobacterium breve, Bifidobacterium longum, and Streptococcus thermophiles (n = 22, (2 probiotic capsules plus honey (n = 21 or (3 placebo capsules (n = 24 all for 6 weeks. Blood and serum samples were collected for one week before radiotherapy and 24-72 h after the end of radiotherapy. Results: White blood cells (WBC, red blood cells (RBC, platelet counts, and serum IgA level were not significantly changed in patients taking probiotic (alone or plus honey during pelvic radiotherapy. The mean decrease in RBC count was 0.52, 0.18, and 0.23 × 10 6 cells/μL, WBC count was 2.3, 1.21, and 1.34 × 10 3 cells/μL and platelet count was, 57.6, 53.3, and 66.35 × 10 3 cells/μL for the probiotic, probiotic plus honey, and placebo groups, respectively. The mean decrease of serum IgA was 22.53, 29.94, and 40.73 mg/dL for the probiotic, probiotic plus honey, and placebo groups, respectively. Conclusion: The observed nonsignificant effect of probiotics may be in favor of local effects of this product in the gut rather than systemic effects, however, as a trend toward a benefit was indicated, further studies are necessary in order to extract effects of

  16. Erythrocytes and the regulation of human skeletal muscle blood flow and oxygen delivery: role of erythrocyte count and oxygenation state of haemoglobin.

    Blood flow to dynamically contracting myocytes is regulated to match O(2) delivery to metabolic demand. The red blood cell (RBC) itself functions as an O(2) sensor, contributing to the control of O(2) delivery by releasing the vasodilators ATP and S-nitrosohaemoglobin with the offloading of O(2) from the haemoglobin molecule. Whether RBC number is sensed remains unknown. To investigate the role of RBC number, in isolation and in combination with alterations in blood oxygenation, on muscle and systemic perfusion, we measured local and central haemodynamics during one-legged knee-extensor exercise ( approximately 50% peak power) in 10 healthy males under conditions of normocythaemia (control), anaemia, anaemia + plasma volume expansion (PVX), anaemia + PVX + hypoxia, polycythaemia, polycythaemia + hyperoxia and polycythaemia + hypoxia, which changed either RBC count alone or both RBC count and oxyhaemoglobin. Leg blood flow (LBF), cardiac output (Q) and vascular conductance did not change with either anaemia or polycythaemia alone. However, LBF increased with anaemia + PVX (28 +/- 4%) and anaemia + PVX + hypoxia (46 +/- 6%) and decreased with polycythaemia + hyperoxia (18 +/- 5%). LBF and Q with anaemia + PVX + hypoxia (8.0 +/- 0.5 and 15.8 +/- 0.7 l min(-1), respectively) equalled those during maximal knee-extensor exercise. Collectively, LBF and vascular conductance were intimately related to leg arterial-venous (a-v) O(2) difference (r(2)= 0.89-0.93; P < 0.001), suggesting a pivotal role of blood O(2) gradients in muscle microcirculatory control. The systemic circulation accommodated to the changes in muscle perfusion. Our results indicate that, when coping with severe haematological challenges, local regulation of skeletal muscle blood flow and O(2) delivery primarily senses alterations in the oxygenation state of haemoglobin and, to a lesser extent, alterations in the number of RBCs and haemoglobin molecules.

    Objective To explore the associations of white blood cell (WBC) count,alanine aminotransferase (ALT),and aspartate aminotransferase(AST) in the first trimester of pregnancy with gestational diabetes mellitus (GDM). Methods Totally 725 GDM women and 935 women who remained euglycemic throughout pregnancy were enrolled in this study. Pre-pregnancy weight/height were recorded. WBC,ALT,and AST levels were detected between 8 and 12 weeks of pregnancy.At 24 to 28 weeks of pregnancy,the glucose and insulin levels were measured. The WBC,ALT,and AST levels were compared between two groups,and the associations of WBC,ALT,and AST levels with the blood glucose and insulin levels were retrospectively analyzed. Meanwhile,the potential associations of those factors with the occurrence of GDM were analzyed. Results WBC count [9.41(8.15,10.84)?10(9)/L vs. 9.04 (7.64,10.37)?10(9)/L,P=1.0?10(-5)] and ALT levels [18.00(12.00,30.00)U/L vs. 16.00 (11.00,26.00)U/L,P=0.004] in the first trimester of pregnancy were significantly increased in GDM subjects than in normal glucose tolerance(NGT)subjects;however,the AST level showed no significant difference between these two groups [41.00 (26.00,43.00)U/L vs. 41.00 (23.00,43.00)U/L,P=0.588]. Logistic regression analysis illustrated that elevated WBC count was an independent risk factor for GDM after adjustment for age,pre-pregnancy body mass index,blood pressure,and family history of diabetes(OR=1.119,P=0.001). The ROC curve revealed that threshold of WBC count was 7.965?10(9)/L(AUC=0.566,P=1?10(-5)),which had a sensitivity of 79.4% and a specificity of 31.3%. Multivariate linear regression analysis showed that homeostasis model assessment of insulin resistance was positively correlated with WBC count(B=0.051,P=0.022,R(2)=0.083);1-hour blood glucose after oral 50 grams of sugar (B=0.044,P=0.001,R(2)=0.044) and fasting plasma true insulin(B=0.214,P=0.032,R(2)=0.066) were positively correlated with WBC count;1-hour true insulin after 100 grams

    Ipilimumab produces durable responses in some metastatic melanoma patients. Neutrophil, platelet, and eosinophil to lymphocyte ratios (NLR, PLR, and ELR) may be associated with the immune response in cancer thereby acting as biomarkers of toxicity and efficacy in ipilimumab-treated patients. Data were collected on clinical characteristics and lactate dehydrogenase (LDH), NLR, PLR, and ELR at baseline, post cycle 2 and at the end of treatment for 183 patients treated with ipilimumab between 2008 and 2015 at the Princess Margaret Cancer Centre. Associations between clinical characteristics, LDH, NLR, PLR, and ELR with toxicity or survival outcomes of progression-free (PFS) and overall survival (OS) were assessed using univariable and multivariable analysis. Prognostic models of outcome at each time point were determined. Of the 183 patients included, the median age was 58, 85% had M1c disease, 58% were performance status 1, and 64% received ipilimumab as second line therapy. Median follow up was 7.5 months (range: 0.3-49.5), median PFS was 2.8 months (95% confidence intervals (CI): 2.8-3.2), and median OS was 9.6 months (95% CI: 7.9-13.2). Prognostic factors for OS by multivariable analysis were LDH and NLR at all-time points. Prognostic models using LDH (× 2 upper limit of normal) and NLR 4) differentiated patients into high, moderate, and low risk of death prior to or on ipilimumab treatment (P < 0.0001 for each model). No factors were associated with toxicity. Prognostic models based on NLR and LDH values at baseline and on treatment differentiate patients into good, intermediate, and poor prognostic groups and may be relevant in patient management.

    Nicotinic receptor agonists decreased the infiltration of eosinophils into the lung and airways in a mouse model of asthma. To better understand the mechanisms implicated in this anti-inflammatory phenomenon, the expression of nicotinic acetylcholine receptors (nAChRs) and the effect of dimethylphenylpiperazinium (DMPP), a nonselective nAChR agonist, on human blood eosinophils were studied. The expression of alpha-3, -4, and -7 nAChR subunits on human blood eosinophils was measured by cell ELISA and immunocytochemistry. mRNA expression for all three subunits was evaluated by quantitative RT-PCR. The effect of DMPP on leukotriene C4 (LTC4) and matrix metalloproteinase-9 (MMP-9) production, eosinophil migration, and intracellular calcium mobilization was measured. The results show that the alpha-3, -4, and -7 nAChR subunits and mRNAs are expressed by blood eosinophils. In vitro treatment of these cells with various concentrations of DMPP reduced platelet-activating factor (PAF)-induced LTC4 production significantly. DMPP (160 microM) decreased eotaxin, and 5-oxo-6,8,11,14-eicosatetranoic acid induced eosinophil migration through Matrigel by 40.9% and 55.5%, respectively. This effect was reversed by the nAChR antagonist mecamylamine. In addition, DMPP reduced MMP-9 release and the inositol 1,4,5-triphosphate-dependent intracellular calcium increase provoked by PAF. Taken together, these results indicate that functional nAChRs are expressed on eosinophils and that nAChR agonists down-regulate eosinophil function in vitro. These anti-inflammatory effects could be of interest in the treatment of allergic asthma.

    False thrombocytopenia may result from platelet aggregation, especially in feline ethylenediamine tetra-acetic acid (EDTA) blood specimens. Citrate, theophylline, adenosine and dipyridamole (CTAD) was added to 46 feline EDTA specimens to test its anti-aggregation action. Platelet aggregation was estimated from blood films and a complete blood count was performed with a Sysmex XT-2000iV analyser. Platelet aggregation score was >2 in 11/46 EDTA tubes and only in one EDTA+CTAD specimen. The platelet count was higher in all CTAD-supplemented tubes except one, medians measured by cytometry being 225.5 × 10(9)/l and 249.0 × 10(9)/l in EDTA and EDTA+CTAD, respectively (P = 0.007). Adding CTAD had statistically and analytically significant but moderate effects on other blood variables, the most intense variations being observed for reticulocytes (about 3% higher in EDTA specimens) and reticulocyte indexes. Addition of CTAD to EDTA when sampling feline blood is a useful option to reduce platelet clumping.

    Background Inflammation is an important underlying mechanism in the pathogenesis of atherosclerosis, and an elevated resting heart rate underlies the process of atherosclerotic plaque formation. We hypothesized an association between resting heart rate and subclinical inflammation. Methods Resting heart rate was recorded at baseline in the KoGES-ARIRANG (Korean Genome and Epidemiology Study on Atherosclerosis Risk of Rural Areas in the Korean General Population) cohort study, and was then divided into quartiles. Subclinical inflammation was measured by white blood cell count and high-sensitivity C-reactive protein. We used progressively adjusted regression models with terms for muscle mass, body fat proportion, and adiponectin in the fully adjusted models. We examined inflammatory markers as both continuous and categorical variables, using the clinical cut point of the highest quartile of white blood cell count (≥7,900/mm3) and ≥3 mg/dL for high-sensitivity C-reactive protein. Results Participants had a mean age of 56.3±8.1 years and a mean resting heart rate of 71.4±10.7 beats/min; 39.1% were men. In a fully adjusted model, an increased resting heart rate was significantly associated with a higher white blood cell count and higher levels of high-sensitivity C-reactive protein in both continuous (P for trend <0.001) and categorical (P for trend <0.001) models. Conclusion An increased resting heart rate is associated with a higher level of subclinical inflammation among healthy Korean people.

    Renal cell carcinoma (RCC) accounts for approximately 3% of adult malignancies. For stage I - III RCC surgery is the primary treatment. Systemic therapy is used in the patients with disseminated disease (stage IV). Sunitinib malate is commonly used in the patients with clear cell renal cell carcinoma (ccRCC) rated as 'low' or 'intermediate' risk according to the Motzer scale. Treatment with sunitinib malate is associated with myelotoxicity. To assess its clinical significance we conducted a pilot study in a group of 10 patients. We noticed a gradual decrease in the mean haemoglobin level during subsequent treatment cycles. Alternations in the platelet count were of no clinical significance. Episodes of the neutropenia were noticed in the study group. In some patients neutrophil count decreased to the level that put them at risk of the infectious complications.

    Eosinophilic gastroenteritis is a rare gastrointestinal disorder with eosinophilic infiltration of the gastrointestinal wall and various gastrointestinal dysfunctions. Diagnosis requires a high index of suspicion and exclusion of various disorders that are associated with peripheral eosinophilia.We report a case of eosinophilic gastroenteritis, which had features of the predominant subserosal type presenting with ascites and hepatic dysfunction, and which responded to a course of low-dose steroid.

  8. Eosinophil secretion of granule-derived cytokines

    2014-10-01

    Full Text Available Eosinophils are tissue-dwelling leukocytes, present in the thymus, and gastrointestinal and genitourinary tracts of healthy individuals at baseline, and recruited, often in large numbers, to allergic inflammatory foci and sites of active tissue repair. The biological significance of eosinophils is vast and varied. In health, eosinophils support uterine and mammary gland development, and maintain bone marrow plasma cells and adipose tissue alternatively activated macrophages, while in response to tissue insult eosinophils function as inflammatory effector cells, and, in the wake of an inflammatory response, promote tissue regeneration and wound healing. One common mechanism driving many of the diverse eosinophil functions is the regulated and differential secretion of a vast array of eosinophil-derived cytokines. Eosinophils are distinguished from most other leukocytes in that many, if not all, of the over three dozen eosinophil-derived cytokines are pre-synthesized and stored within intracellular granules, poised for very rapid, stimulus-induced secretion. Eosinophils engaged in cytokine secretion in situ utilize distinct pathways of cytokine release that include: classical exocytosis, whereby granules themselves fuse with the plasma membrane and release their entire contents extracellularly; piecemeal degranulation, whereby granule-derived cytokines are selectively mobilized into vesicles that emerge from granules, traverse the cytoplasm and fuse with the plasma membrane to release discrete packets of cytokines; and eosinophil cytolysis, whereby intact granules are extruded from eosinophils, and deposited within tissues. In this latter scenario, extracellular granules can themselves function as stimulus-responsive secretory-competent organelles within the tissue. Here we review the distinctive processes of differential secretion of eosinophil granule-derived cytokines.

    Eosinophilic granuloma occurs almost exclusively in the diaphysis or metaphysis, when tubular bones are affected. The investigators present an extremely rare case of eosinophilic granuloma arising at the epiphysis of the femoral head in an 8-year-old boy. Plain radiographs and computed tomography showed a well-circumscribed radiolucent lesion, suggesting chondroblastoma or Brodie's abscess. However, the findings on magnetic resonance images were different from typical features of chondroblastoma or Brodie's abscess. The lesion was curetted. Histological diagnosis was eosinophilic granuloma. Differential diagnoses of a radiolucent lesion at the epiphysis in a child should include, though quite rare, eosinophilic granuloma.

    Full Text Available Background & Objective: The regular exercise training is known as a preventive and adjuvant therapy in inflammatory diseases such as cancer. The aim of this study was to determine the effect of the aerobic training on IL-10 and IL-8 levels and the count of white blood cells (WBC in women with breast cancer. Material & Methods: The statistical society of the present study included Kerman women with breast cancer. Forty patients with breast cancer were randomly divided into two groups: exercise (n = 20 and control (n = 20. The exercise group performed the endurance training for 8 weeks with the intensity between 40 to 55 percent of the target heart rate. Twenty four hours before the first session and 48 hours after the last session of the exercise protocol, blood samples were taken from both groups and then IL-10 and IL-8 levels in serum were measured by ELISA via a Boster kit. Results: The results of the present study showed that 8 weeks of the endurance exercise training did not significantly increase the IL-10 (P=0.113 serum level, but increased the WBC count (p=0.019 and decreased the serum level of IL-8 (p=0.03 significantly. Conclusion: According to the results of the present study, regular endurance training via decreasing the inflammatory factors can be considered as an effective factor along with other therapies in improving breast cancer.

    Sparganosis is a rare parasitic disease caused by migrating plerocercoid tapeworm larva of the genus Spirometra. Infection in humans is mainly caused by the ingestion of raw or inadequately cooked flesh of infected frogs, snakes, and chickens. Here, we report a rare case of a 45-year-old man who was admitted to our hospital with left lower chest pain. The chest radiograph and computed tomography (CT) scan revealed localized pleural effusion in the left lower lobe; further, peripheral blood eosinophilia and eosinophilic pleural effusion were present. Percutaneous catheter drainage was performed, which revealed long worm-shaped material that was identified as a sparganum by DNA sequencing. The patient showed clinical improvement after drainage of the sparganum. This study demonstrates the importance of considering parasitic diseases in the differential diagnosis of eosinophilic pleural effusion.

    2016-01-01

    Radioactive131 iodine (RAI) body burden is estimated in thyroid cancer patients by a) exposure rate meter and b) external probe counting. A calibration factor of 301 cpm/MBq (d = 16 cm) is used for the probe for estimates of whole body activity. Patients sit in a rotating stool with their center corresponding to the field of view for estimation of whole body RAI. Radioactive counts are obtained for anterio posterior (AP) and postero anterior (PA) geometries. Whole body retention factor is expressed as a ratio against assayed activity administered to the patient on day 1. With exposure rate measurement, for off-thyroxin (hypothyriod) patients, the retention factors were 0.148 ± 0.12 (n = 211) and 0.07 ± 0.08 (n = 68) at 48 h and 72 h, respectively. For recombinant TSH (rhTSH) (euthyroid) group, the retention factors were 0.089 ± 0.06 (n = 24) and 0.05 ± 0.05 (n = 19) at 48 h and 72 h, respectively. By probe counting method, the obtained retention factors were 0.081 ± 0.013 (range: 0.071–0.096) (off-thyroxine group) and 0.039 ± 0.03 (range: 0.008–0.089) for the rhTSH group at 48 h. The 72 h retentions in the off thyroxine (hypothyriod) group and the rhTSH (euthyroid) group were 0.048 ± 0.024 (range: 0.016–0.076) and 0.005, respectively. The radioactive body burdens at 48 h were in the range of 290-315 MBq (7.8–8.5 mCi) for the off-thyroxine group and 44–286 MBq (1.2–7.7 mCi) for the rhTSH group. The calculated residence times in whole body were 21.97 ± 3.8 h (range: 17.1–27.1) for off-thyroxine group and 14.28 ± 2.75 h (range: 9.97-19.46) showing high statistical significance (P radioactive iodine. There was no correlation between administered activity and retained body burden at 48 h or 72 h. PMID:27651735

  16. Pattern-recognition receptors in human eosinophils.

    Science.gov (United States)

    Kvarnhammar, Anne Månsson; Cardell, Lars Olaf

    2012-05-01

    The pattern-recognition receptor (PRR) family includes Toll-like receptors (TLRs), nucleotide-binding oligomerization domain (NOD) -like receptors (NLRs), RIG-I-like receptors (RLRs), C-type lectin receptors (CLRs) and the receptor for advanced glycation end products (RAGE). They recognize various microbial signatures or host-derived danger signals and trigger an immune response. Eosinophils are multifunctional leucocytes involved in the pathogenesis of several inflammatory processes, including parasitic helminth infection, allergic diseases, tissue injury and tumour immunity. Human eosinophils express several PRRs, including TLR1-5, TLR7, TLR9, NOD1, NOD2, Dectin-1 and RAGE. Receptor stimulation induces survival, oxidative burst, activation of the adhesion system and release of cytokines (interleukin-1β, interleukin-6, tumour necrosis factor-α and granulocyte-macrophage colony-stimulating factor), chemokines (interleukin-8 and growth-related oncogene-α) and cytotoxic granule proteins (eosinophil cationic protein, eosinophil-derived neurotoxin, eosinophil peroxidase and major basic protein). It is also evident that eosinophils play an immunomodulatory role by interacting with surrounding cells. The presence of a broad range of PRRs in eosinophils indicates that they are not only involved in defence against parasitic helminths, but also against bacteria, viruses and fungi. From a clinical perspective, eosinophilic PRRs seem to be involved in both allergic and malignant diseases by causing exacerbations and affecting tumour growth, respectively.

    1991-02-01

    The complex effects of the anthelminthic Fenbion (prepared on the basis of fenbendazole, Bioveta Nitra) were investigated; its effects on the blood picture were studied in heifers with the liveweight of 400 kg, until the sixth day after its single application at doses of 15 and 30 mg per kg liveweight. The haemoglobin (Hb) content decreased in keeping with the physiological standard. The haematocrit (Hk) value decreased below the reference standard from 0.31 and 0.32 l per l on days five and six to 0.28-0.29 l per l. The total leucocyte counts increased from 8.60-9.64 G per l to 10.54-11.0 G per 1. This means that on the first days after administration Fenbion has negative effects on erythropoiesis, and as a stressor it evokes defense reactions of the organism. Differential blood counting: leucocyte counts increased to 0.71-0.73 arb. u. on days three to four. The increase in lymphocyte counts in the blood after Fenbion administration is likely to be related to the cellular immunobiological defense reaction of the organism. The counts of segmented leucocytes decreased, the counts of eosinophils increased irregularly, those of basophils and monocytes were highly variable, and the counts of monocytes increased irregularly in a large span, or they decreased.

    A retrospective study of cases of a unique intramural inflammatory mass within the feline gastrointestinal tract was performed in order to describe and characterize the lesion. Twenty-five cases were identified from archival surgical and postmortem tissues. The lesion most often occurred as an ulcerated intramural mass at the pyloric sphincter (n = 12) or the ileocecocolic junction or colon (n = 9); the remaining cases were in the small intestine. Seven cases also had lymph node involvement. The lesions were characterized by eosinophilic inflammation, large reactive fibroblasts, and trabeculae of dense collagen. Intralesional bacteria were identified in 56% of the cases overall and all of the ileocecocolic junction and colon lesions. Fifty-eight percent of cats tested had peripheral eosinophilia. Cats treated with prednisone had a significantly longer survival time than those receiving other treatments. We propose that this is a unique fibroblastic response of the feline gastrointestinal tract to eosinophilic inflammation that in some cases is associated with bacteria. The lesion is often grossly and sometimes histologically mistaken for neoplasia.

    A retrospective study was conducted on skin specimens from 24 cats with eosinophilic granuloma complex. The specimens were stained with haematoxylin and eosin and Gallego's trichrome stain. In all specimens, flame figures and/or large foci of so-called "collagen degeneration" were detected and histopathological features were not predictive of the clinical picture. Use of the term eosinophilic dermatosis was advocated in diagnostic dermatopathology. On trichrome-stained sections, normally stained collagen fibres were identified in the middle of both flame figures and large foci of "collagen degeneration" and the debris surrounding collagen bundles showed the same tinctorial properties as eosinophil granules. Eosinophil degranulation around collagen bundles seemed to represent the major pathogenetic event in these lesions, analogous with human flame figures. The term flame figures might therefore be more accurately used to designate those foci of eosinophilic to partly basophilic debris commonly referred to as "collagen degeneration".

    It is a well-known fact that histamine is involved in eosinophil-dependent inflammatory responses including cellular chemotaxis and migration. Nevertheless, the relative role of histamine receptors in the mechanisms of eosinophils adhesion to endothelial cells is not known. Therefore the aim of presented study was to examine the effect of selective histamine receptors ligands on eosinophils adhesion to endothelium. For that purpose the highly purified human eosinophils have been isolated from the peripheral blood. The viability and functional integrity of isolated eosinophils have been validated in several tests. Histamine as well as 4-methylhistamine (selective H4 agonist) in concentration-dependent manner significantly increased number of eosinophils that adhere to endothelium. Among the selective histamine receptors antagonist or H1 inverse agonist only JNJ7777120 (histamine H4 antagonist) and thioperamide (dual histamine H3/H4 antagonist) had direct effect on eosinophils adhesion to endothelial cells. Antagonists of H1 (diphenhydramine, mepyramine) H2 (ranitidine and famotidine) and H3 (pitolisant) histamine receptors were ineffective. To the best of our knowledge, this is the first study to demonstrate that histamine receptor H4 plays a dominant role in histamine-induced eosinophils adhesion to endothelium.

  1. The role of the eosinophil-selective chemokine, eotaxin, in allergic and non-allergic airways inflammation

    Full Text Available Blood eosinophilia and tissue infiltration by eosinophils are frequently observed in allergic inflammation and parasitic infections. This selective accumulation of eosinophils suggested the existence of endogenous eosinophil-selective chemoattractants. We have recently discovered a novel eosinophil-selective chemoattractant which we called eotaxin in an animal model of allergic airways disease. Eotaxin is generated in both allergic and non-allergic bronchopulmonary inflammation. The early increase in eotaxin paralled eosinophil infiltration in the lung tissue in both models. An antibody to IL-5 suppressed lung eosinophilia, correlating with an inhibition of eosinophil release from bone marrow, without affecting eotaxin generation. This suggests that endogenous IL-5 is important for eosinophil migration but does not appear to be a stimulus for eotaxin production. Constitutive levels of eotaxin observed in guinea-pig lung may be responsible for the basal lung eosinophilia observed in this species. Allergen-induced eotaxin was present mainly in the epithelium and alveolar macrophages, as detected by immunostaining. In contrast there was no upregulation of eotaxin by the epithelial cells following the injection of Sephadex beads and the alveolar macrophage and mononuclear cells surrounding the granuloma were the predominant positive staining cells. Eotaxin and related chemokines acting through the CCR3 receptor may play a major role in eosinophil recruitment in allergic inflammation and parasitic diseases and thus offer an attractive target for therapeutic intervention.

    Ovine animal models are widely used to conduct preclinical studies, e.g., to evaluate cardiovascular prostheses intended to be applied in man. However, although analyzed in many of those studies, information about ovine blood reference values is scanty. The aim of this study is to establish a reference list of ovine blood parameters relevant for blood coagulation. A cohort of 47 mature ewes was evaluated. Parameters comprised the following: cells and cellular components-platelet, red, and white cell counts (including subsets), hemoglobin (Hb), hematocrit (HCT), mean corpuscular hemoglobin (MCH) and mean corpuscular volume (MCV), and MCH concentration (MCHC); global tests of coagulation-prothrombin time (Quick's time) and activated partial thromboplastin time (aPTT); and parameters relevant for blood coagulation-fibrinogen, antithrombin (AT), and von Willebrand Factor. After explorative data analysis, a list of ovine reference values was established. Interestingly, a comparison with human reference values revealed some interspecies differences between sheep and man, i.e., much higher ovine ranges for some cell counts (neutrophils, lymphocytes, basophils, eosinophils, and platelets) but lower values for some other parameters (Hb, HCT, MCV, MCH, AT, and Quick's test). We established a reference list of ovine blood count and blood coagulation parameters. Because of some peculiarities of the ovine blood, this list may have implications for the interpretation of experimental data.

    After surgery, breast cancer patients are offered adjuvant chemotherapy to avoid cancer cell spread. During chemotherapy process, neutrophils could fall relatively, and side effects could spike to the peak. Therefore, the medical care personnel should prevent the progression of the side effects. This study aimed to examine the effects of Chan-Chuang qi-gong therapy on complete blood counts in breast cancer patients treated with chemotherapy. This study used a quasi-experimental design. The experiment group (n = 32) received a 21-day Chan-Chuang qi-gong therapy, whereas the control group (n = 35) did not. White blood cells, platelet, and hemoglobin were measured on the day before chemotherapy and on days 8, 15, and 22 during chemotherapy. According to this study, there were significant differences in white blood cells (F = 115.76, P qi-gong therapy may decrease leukopenia in breast cancer patients treated with chemotherapy. It is recommended conducting more studies on qi-gong and then introducing it in clinical nursing practice at an appropriate time to promote quality of nursing care and quality of patient life.

    Full Text Available Eosinophilic gastroenteritis is a rare condition characterized by recurrent eosinophilic infiltration of portions of the GI tract and presenting with nonspecific GI symptoms in association with peripheral eosinophilia. Its etiology and pathogenesis remain unclear and its symptoms overlap with many GI and systemic diseases. Thus, both gastroenterologists and general internists need to be aware of this rare condition. We present a case of a 55-year-old male with diffuse abdominal pain and distention for two weeks. His physical examination was significant for moderate ascites. Initial work-up demonstrated severe peripheral blood eosinophilia, normal liver function tests, thickening of the stomach and small bowel wall, and elevated serum IgE. Upper endoscopy and extensive testing for malignancy and parasitic infections failed to establish a diagnosis. Ascitic fluid analysis showed significant eosinophilia. Further, a full-thickness jejunal showed marked eosinophilic infiltration of the serosa and muscularis propria. Subsequent treatment with oral prednisone resulted in normalization of laboratory and radiologic abnormalities in a few week period.

    1999-01-01

    Full Text Available Eosinophilic granulocytes are major effector cells in inflammation. Extracellular deposition of toxic eosinophilic granule proteins (EGPs, but not the presence of intact eosinophils, is crucial for their functional effect in situ. As even recent morphometric approaches to quantify the involvement of eosinophils in inflammation have been only based on cell counting, we developed a new method for the cell‐independent quantification of EGPs by image analysis of immunostaining. Highly sensitive, automated immunohistochemistry was done on paraffin sections of inflammatory skin diseases with 4 different primary antibodies against EGPs. Image analysis of immunostaining was performed by colour translation, linear combination and automated thresholding. Using strictly standardized protocols, the assay was proven to be specific and accurate concerning segmentation in 8916 fields of 520 sections, well reproducible in repeated measurements and reliable over 16 weeks observation time. The method may be valuable for the cell‐independent segmentation of immunostaining in other applications as well.

    Full Text Available Abstract Background Nosocomial bacteremia is associated with a poor prognosis. Early adequate therapy has been shown to improve outcome. Consequently, rapid detection of a beginning sepsis is therefore of the utmost importance. This historical cohort study was designed to evaluate if different patterns can be observed in either C-reactive protein (CRP and white blood cell count (WCC between Gram positive bacteremia (GPB vs. Gram negative bacteremia (GNB, and to assess the potential benefit of serial measurements of both biomarkers in terms of early antimicrobial therapy initiation. Methods A historical study (2003–2004 was conducted, including all adult intensive care unit patients with a nosocomial bacteremia. CRP and WCC count measurements were recorded daily from two days prior (d-2 until one day after onset of bacteremia (d+1. Delta (Δ CRP and Δ WCC levels from the level at d-2 onward were calculated. Results CRP levels and WCC counts were substantially higher in patients with GNB. Logistic regression analysis demonstrated that GNB and Acute Physiology and Chronic Health Evaluation (APACHE II score were independently associated with a CRP increase of 5 mg/dL from d-2 to d+1, and both were also independently associated with an increase of WCC levels from d-2 to d+1 of 5,000 × 103 cells/mm3. Conclusion Increased levels of CRP and WCC are suggestive for GNB, while almost unchanged CRP and WCC levels are observed in patients with GPB. However, despite the different patterns observed, antimicrobial treatment as such cannot be guided based on both biomarkers.

    Thirty-nine samples of synovial fluid were collected from the joints of 32 horses with suspected septic arthritis and 39 samples were collected from horses euthanased for non-orthopaedic conditions. The white blood cell counts (WBCC) were determined and the pro and active forms of matrix metalloproteinases (MMPs) 2 and 9 were measured by gelatin zymography and image analysis in each sample. The initial measurements of the ratio of proMMP9:proMMp2 and WBCC were good prognostic indicators of the survival of the horses. There was no significant relationship between the interval between the injury and the horse being referred for treatment and either the WBCC or the levels of MMP2 and MMP9 initially, and no evidence that this interval significantly affected the chances of the horses surviving.

    Full Text Available This study was conducted to determine the effect of using plant essential oils in triticale-based broiler diets as alternative to antimicrobial growth promotors (AGPs on growth, E.coli counts in small intestine and blood parameters. 720 male broiler chicks were randomly distributed to nine experimental groups with four replicates. The control group received the triticale-soybean meal basal diet. In the other treatment groups the basal diet was supplemented with one of the following; flavomycin, enzyme, flavomycin+enzyme, enzyme+thyme oil, enzyme+fennel oil, enzyme+bay leaf oil, enzyme+thyme oil+fennel oil and enzyme+thyme oil+fennel oil+bay leaf oil. Results showed that the weight gain and feed intake were not influenced by the treatments (P>0,05. The use of the combination of plant extracts significantly improved the feed conversion. Use of plant extracts in triticale-based broiler diets as an alternative to AGPs had no regular effect on E.coli count in small intestine segments (P>0,05. Feeding broiler chickens with the enzyme+thyme oil supplemented diets increased eritrocyte level in serum (P0,05 by the treatments. In conclusion, these plant ectracts can be also used with enzyme in triticale-based broiler diets as alternative to AGPs.

    This study was undertaken to determine whether concentrations of procalcitonin in the blood of neonates with nosocomial infections depend on the type of pathogen. Qualification for the study group was based on the clinical signs of infection. We found that infections with Gram-positive (chiefly coagulase-negative staphylococci) and Gram-negative bacteria are accompanied by elevated concentrations of procalcitonin. In the case of Gram-positive bacteria, other laboratory signs of infection studied by us (concentration of C-reactive protein, white blood cell count, immature-to-total neutrophil ratio) were not discriminatory, confirming the diagnostic usefulness of procalcitonin measurements in nosocomial infections of the neonate with Gram-negative or Gram-positive bacteria.

    Full Text Available miR-155 has been confirmed to be a key factor in immune responses in humans and other mammals. Therefore, investigation of variations in miR-155 could be useful for understanding the differences in immunity between individuals. In this study, four SNPs in miR-155 were identified in mice (Mus musculus and humans (Homo sapiens. In mice, the four SNPs were closely linked and formed two miR-155 haplotypes (A and B. Ten distinct types of blood parameters were associated with miR-155 expression under normal conditions. Additionally, 4 and 14 blood parameters were significantly different between these two genotypes under normal and lipopolysaccharide (LPS stimulation conditions, respectively. Moreover, the expression levels of miR-155, the inflammatory response to LPS stimulation and the lethal ratio following Salmonella typhimurium infection were significantly increased in mice harboring the AA genotype. Further, two SNPs, one in the loop region and the other near the 3' terminal of pre-miR-155, were confirmed to be responsible for the differential expression of miR-155 in mice. Interestingly, two additional SNPs, one in the loop region and the other in the middle of miR-155*, modulated the function of miR-155 in humans. Predictions of secondary RNA structure using RNAfold showed that these SNPs affected the structure of miR-155 in both mice and humans. Our results provide novel evidence of the natural functional SNPs of miR-155 in both mice and humans, which may affect the expression levels of mature miR-155 by modulating its secondary structure. The SNPs of human miR-155 may be considered as causal mutations for some immune-related diseases in the clinic. The two genotypes of mice could be used as natural models for studying the mechanisms of immune diseases caused by abnormal expression of miR-155 in humans.

    Hypereosinophilic syndromes (HESs) are a diverse group of conditions characterized by clinical manifestations attributable to eosinophilia and eosinophilic infiltration of tissues. HESs are chronic disorders with significant morbidity and mortality. Although the availability of targeted chemotherapeutic agents, including imatinib, has improved quality of life and survival in some patients with HESs, additional agents with increased efficacy and decreased toxicity are sorely needed. The purpose of this review is to provide an overview of eosinophil biology with an emphasis on potential targets of pharmacotherapy and to provide a summary of potential eosinophil-targeting agents, including those in development, in clinical trials, or approved for other disorders.

    Full Text Available Total white blood cell (WBC and neutrophil counts are lower among individuals of African descent due to the common African-derived "null" variant of the Duffy Antigen Receptor for Chemokines (DARC gene. Additional common genetic polymorphisms were recently associated with total WBC and WBC sub-type levels in European and Japanese populations. No additional loci that account for WBC variability have been identified in African Americans. In order to address this, we performed a large genome-wide association study (GWAS of total WBC and cell subtype counts in 16,388 African-American participants from 7 population-based cohorts available in the Continental Origins and Genetic Epidemiology Network. In addition to the DARC locus on chromosome 1q23, we identified two other regions (chromosomes 4q13 and 16q22 associated with WBC in African Americans (P<2.5×10(-8. The lead SNP (rs9131 on chromosome 4q13 is located in the CXCL2 gene, which encodes a chemotactic cytokine for polymorphonuclear leukocytes. Independent evidence of the novel CXCL2 association with WBC was present in 3,551 Hispanic Americans, 14,767 Japanese, and 19,509 European Americans. The index SNP (rs12149261 on chromosome 16q22 associated with WBC count is located in a large inter-chromosomal segmental duplication encompassing part of the hydrocephalus inducing homolog (HYDIN gene. We demonstrate that the chromosome 16q22 association finding is most likely due to a genotyping artifact as a consequence of sequence similarity between duplicated regions on chromosomes 16q22 and 1q21. Among the WBC loci recently identified in European or Japanese populations, replication was observed in our African-American meta-analysis for rs445 of CDK6 on chromosome 7q21 and rs4065321 of PSMD3-CSF3 region on chromosome 17q21. In summary, the CXCL2, CDK6, and PSMD3-CSF3 regions are associated with WBC count in African American and other populations. We also demonstrate that large inter

    2015-06-01

    Eosinophilic folliculitis (EF) is an idiopathic dermatitis included in the spectrum of eosinophilic pustular follicular reactions. Demodex folliculorum has been implicated as contributing to the pathogenesis of human immunodeficiency virus-associated EF, but it has not been described outside this context. We present an immunocompetent 65-year-old white man with a 5-year history of recurrent pruritic erythematous and oedematous lesions on his face, neck and scalp. Histopathologically, an eosinophilic microabcess with Demodex folliculorum mite within a pilosebaceous follicle was seen, and considered the causal agent. There were also accumulations of eosinophil granules on collagen bundles, and flame figure formations in the dermis. We believe that 'eosinophilic follicular reaction' is an appropriate term to describe this case of EF induced by D. folliculorum and thus distinguish it from the idiopathic form of EF. Moreover, this case suggests that D. folliculorum can sometimes induce an eosinophilic immune reaction.

    This report describes the clinical presentation of two Cavalier King Charles spaniels with different eosinophilic diseases. The first case presented with dyspnoea and a non-productive cough, and investigations demonstrated eosinophilic bronchopneumonopathy. The second dog was referred for the investigation of haemorrhagic vomiting and diarrhoea and was eventually diagnosed with eosinophilic enteritis. Both dogs had concurrent eosinophilic stomatitis, and both responded completely to immunosuppressive glucocorticoid therapy. This report is the first to describe the concurrence of eosinophilic stomatitis and systemic eosinophilic disease in Cavalier King Charles spaniels, and suggest that this breed may be predisposed to eosinophilic syndromes.

    Full Text Available Abstract Background Soccer is a form of exercise that induces inflammatory response, as well as an increase in free radicals potentially leading to muscle injury. Balanced nutritional intake provides important antioxidant vitamins, including vitamins A, C and E, which may assist in preventing exercise-related muscle damage. The purpose of the present study was to determine the effect of macro/micronutrient intake on markers of oxidative stress, muscle damage, inflammatory and immune response in female soccer players. Methods Twenty-eight female players belonging to two soccer teams of the same professional soccer club participated in this study after being informed about the aims and procedures and after delivering written consent. Each team completed an 8-day dietary record and played one competition match the same week. Participants were divided into two groups: the REC group (who complied with recommended intakes and the NO-REC group (who were not compliant. Laboratory blood tests were carried out to determine hematological, electrolytic and hormonal variables, as well as to monitor markers of cell damage and oxidative stress. Blood samples were obtained 24 h before, immediately after and 18 h after official soccer matches. Student t-test or Mann–Whitney U-test was used to compare both groups throughout the match. Results At rest, we observed that the REC group had higher levels of total antioxidant status (TAS, glutathione peroxidase (GPx, and lower levels of creatine kinase (CK and lactate dehydrogenase (LDH in comparison to the NO-REC group. Immediately after the match, levels of TAS, GPx, superoxide dismutase (SOD, LDH and % lymphocytes were higher and the % of neutrophils were lower in the REC group compared to the NO-REC group. These differences were also maintained 18 h post-match, only for TAS and GPx. Conclusions Our data reveal an association between nutritional intake and muscle damage, oxidative stress, immunity and inflammation

    A 3-year-old boy developed transient protein-losing gastroenteropathy associated with cytomegalovirus (CMV) infection. Both IgG and IgM antibodies to CMV were positive in a serologic blood test. Upper gastrointestinal endoscopy showed multiple erosions throughout the body of the stomach, without enlarged gastric folds. Histological examination of the biopsy specimens indicated eosinophilic gastroenteritis and CMV infection. The patient had complete resolution without specific therapy for CMV in four weeks. An allergic reaction as well as CMV infection played important roles in the pathogenesis of this case.

    Interest in childhood metabolic syndrome (MetS) has increased substantially due to the increasing prevalence of childhood obesity on a global scale. Early recognition of MetS is critical in order to delay the development of cardiovascular disease (CVD). In this study, we evaluated the relationship between complete blood count (CBC) parameters and MetS among pre-pubertal children which may provide evidence in support of using low cost, readily available clinical haematological parameters for the detection of MetS. A retrospective analysis was carried out on 330 (125 lean vs. 205 overweight) Turkish pre-pubertal children who attend to a paediatric outpatient clinic. Age, gender, puberty, body mass index, CBC parameters, cardiometabolic risk factors including lipid profiles, high sensitive serum reactive protein (hsCRP) and insulin resistance index calculated by homeostasis model assessment (HOMA-IR) were evaluated and compared among lean, overweight children and children with MetS. The mean age of the study population was 7.4 ± 1.9 years. In both gender, the mean values of mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) were significantly lower and red blood cell (RBC), platelet (PLT) counts were significantly higher in overweight children. Overall, 8.4% (n = 28) of patients met the criteria of MetS. Children with MetS had higher levels of PLT and lower levels of mean platelet volume (MPV). Of all the haematological parameters analysed, PLT was positively, whereas MPV was negatively correlated with MetS in girls. In addition, MPV was inversely correlated with fasting blood glucose, HOMA-IR, low density lipoprotein-cholesterol (LDL-C) and low density lipoprotein-cholesterol/high density lipoprotein-cholesterol (LDL-C/HDL-C) ratio in girls after adjusting for confounding factors. The risk analyses of MetS in terms of MPV quartiles showed that the adjusted OR (95% CI) for the lowest vs. the

    Full Text Available Finding of increased numbers of eosinophils in the muscle in cases of acute appendicitis has led to the hypothesis that it may have an allergic origin. This study aimed to measure the eosinophil degranulation resulting in a rise in the serum of eosinophil granule proteins that would be expected in such cases. The levels of serum eosinophil cationic protein (ECP measured by chemiluminescence assay in acute appendicitis were compared, with those of appropriate controls. Mean (95% CI serum ECP (µg/L levels were: acute appendicitis 45.3 (27.7-63.0; normal appendix 22.7 (16.0-29.3; asthma 24.2 (4.6-43.8; and healthy volunteers 13.2 (8.3-18.1. In cases of acute appendicitis, there is an inverse relationship between duration of symptoms and serum ECP. However, this was not statistically significant. Significant local eosinophil activation and degranulation occurs in acute appendicitis, enough to cause a rise in serum levels of eosinophil chemotactic protein

    Eosinophilic gastroenteritJs (EGE) in the adult is a distinctive pathologically-based disorder characterized by an eosinophil-predominant mucosal inflammatory process. Most often, the disorder is detected during endoscopic investigation for abdominal pain or diarrhea. Other causes of gastric and intestinal mucosal eosinophilia require exclusion, including parasitic infections and drug-induced causes. Occasionally, the muscle wall or serosal surface may be involved. EGE appears to be more readily recognized, in large part, due to an evolution in the imaging methods used to evaluate abdominal pain and diarrhea, in particular, endoscopic imaging and mucosal biopsies. Definition of EGE, however, may be difficult, as the normal ranges of eosinophil numbers in normal and abnormal gastric and intestinal mucosa are not well standardized. Also, the eosinophilic inflammatory process may be either patchy or diffuse and the detection of the eosinophilic infiltrates may vary depending on the method of biopsy fixation. Treatment has traditionally focused on resolution of symptoms, and, in some instances, eosinophil quantification in pre-treatment and post-treatment biopsies. Future evaluation and treatment of EGE may depend on precise serological biomarkers to aid in definition of the long-term natural history of the disorder and its response to pharmacological or biological forms of therapy.

    Epidemiology supports a causal link between air pollutant exposure and childhood asthma, but the mechanisms are unknown. We have previously reported that ozone exposure can alter the anatomic distribution of CD25+ lymphocytes in airways of allergen-sensitized infant rhesus monkeys. Here, we hypothesized that ozone may also affect eosinophil trafficking to allergen-sensitized infant airways. To test this hypothesis, we measured blood, lavage, and airway mucosa eosinophils in 3-month old monkeys following cyclical ozone and house dust mite (HDM) aerosol exposures. We also determined if eotaxin family members (CCL11, CCL24, CCL26) are associated with eosinophil location in response to exposures. In lavage, eosinophil numbers increased in animals exposed to ozone and/or HDM. Ozone + HDM animals showed significantly increased CCL24 and CCL26 protein in lavage, but the concentration of CCL11, CCL24, and CCL26 was independent of eosinophil number for all exposure groups. In airway mucosa, eosinophils increased with exposure to HDM alone; comparatively, ozone and ozone + HDM resulted in reduced eosinophils. CCL26 mRNA and immunofluorescence staining increased in airway mucosa of HDM alone animals and correlated with eosinophil volume. In ozone + HDM animal groups, CCL24 mRNA and immunofluorescence increased along with CCR3 mRNA, but did not correlate with airway mucosa eosinophils. Cumulatively, our data indicate that ozone exposure results in a profile of airway eosinophil migration that is distinct from HDM mediated pathways. CCL24 was found to be induced only by combined ozone and HDM exposure, however expression was not associated with the presence of eosinophils within the airway mucosa. -- Highlights: Black-Right-Pointing-Pointer Ozone can modulate the localization of eosinophils in infant allergic airways. Black-Right-Pointing-Pointer Expression of eotaxins within the lung is affected by ozone and allergen exposure. Black-Right-Pointing-Pointer CCL24 induction by

    Background: SNARE members mediate membrane fusion during intracellular trafficking underlying innate and adaptive immune responses by different cells. However, little is known about the expression and function of these proteins in human eosinophils, cells involved in allergic, inflammatory and immunoregulatory responses. Here, we investigate the expression and distribution of the Qa-SNARE syntaxin17 (STX17) within human eosinophils isolated from the peripheral blood. Methods: Flow cytometry and a pre-embedding immunonanogold electron microscopy (EM) technique that combines optimal epitope preservation and secondary Fab-fragments of antibodies linked to 1.4 nm gold particles for optimal access to microdomains, were used to investigate STX17. Results: STX17 was detected within unstimulated eosinophils. Immunogold EM revealed STX17 on secretory granules and on granule-derived vesiculotubular transport carriers (Eosinophil Sombrero Vesicles-EoSVs). Quantitative EM analyses showed that 77.7% of the granules were positive for STX17 with a mean±SEM of 3.9±0.2 gold particles/granule. Labeling was present on both granule outer membranes and matrices while EoSVs showed clear membrane-associated labeling. STX17 was also present in secretory granules in eosinophils stimulated with the cytokine tumor necrosis factor alpha (TNF-α) or the CC-chemokine ligand 11 CCL11 (eotaxin-1), stimuli that induce eosinophil degranulation. The number of secretory granules labeled for STX17 was significantly higher in CCL11 compared with the unstimulated group. The level of cell labeling did not change when unstimulated cells were compared with TNF-α-stimulated eosinophils. Conclusions: The present study clearly shows by immunanonogold EM that STX17 is localized in eosinophil secretory granules and transport vesicles and might be involved in the transport of granule-derived cargos. - Highlights: • First demonstration of the Qa-SNARE syntaxin-17 (STX17) in human eosinophils. • High

    BACKGROUND:Course of diabetes and hypertension are independent risk factors for diabetic microvascular complications, and fasting C-peptide level is a protective factor. There are many studies concerning glycated hemoglobin, C-reactive protein, white blood cel count and diabetic microvascular complications, but studies about neutrophils are rarely reported. OBJECTIVE:To investigate the relationship of peripheral blood neutrophil count with diabetic microvascular complications. METHODS:Totaly 112 patients with type 2 diabetes melitus were selected and divided into two groups according to the presence or absence of microvascular complications: diabetes group and diabetes+ microvascular complication group. The gender, age, ethnic group, disease history and laboratory examination parameters were colected and analyzed with univariate analysis and multivariate analysis. RESULTS AND CONCLUSION:(1) Univariate analysis: Patients in the diabetes+microvascular complication group had significantly higher age, course of diabetes, globulin, creatinine, the percentage of neutrophile granulocytes, nertrophil count, rate of hypertension than those in the diabetes group (P < 0.05), while the lymphocyte percentage, glomerular filtration rate, and triglyceride level were significantly lower than those in the diabetes group (P < 0.05). (2) Logistic regression analysis showed that age, course of diabetes and nertrophil count were the independent risk factors of microvascular complications in patients with type 2 diabetes melitus (odds ratio=1.155, 2.145, 2.275, alP < 0.01). Based on the adjustment of the age factor, the partial correlation analysis showed that the nertrophil count was positively correlated to the levels of creatinine, low-density lipoprotein cholesterol, globulin and hemoglobin, but negatively correlated to the levels of serum bile acid and glomerular filtration rate. Chronic subclinical inflammations are closely correlated to the occurrence of microvascular

    Eosinophils play a major role in asthma. One described mechanism leading to the impaired clearance of these cells from the lung is the delay in their programmed cell death (apoptosis). β(2)-Adrenoceptor agonists have been shown to prolong survival and delay apoptosis of eosinophils. The aim of the present study was to evaluate the mechanisms, especially the role of cAMP pathway, in the prolongation of human eosinophil survival by a selective β(2)-agonist salbutamol. Isolated human peripheral blood eosinophils were cultured in the absence or presence of a β(2)-agonist salbutamol and the indicated antagonists/inhibitors under sterile conditions. Apoptosis was measured by using the relative DNA fragmentation assay and Annexin-V binding. Salbutamol prolonged survival of human eosinophils and it was inhibited by a β-receptor antagonist propranolol and mimicked by cell-permeant cAMP analogues dibutyryl- and 8-bromo-cAMP. Pharmacological inhibitors of adenylyl cyclase (SQ-22,536) and protein kinase A (Rp-8-CPT-cAMPS) antagonized the effects of salbutamol. The survival-prolonging action of salbutamol was potentiated by a phosphodiesterase inhibitor rolipram (EC(50) for the salbutamol effect was 13.6 ± 4.0 and 8.1 ± 3.1 nM in the absence and presence of rolipram, respectively; p=0.0142, n=10). In contrast, inhibition of Ca(2+)-activated K(+)-channels by apamin, charybdotoxin, iberiotoxin or paxilline did not affect the ability of salbutamol to prolong eosinophil survival. Taken together, the present results suggest that salbutamol at clinically relevant concentrations decreases apoptosis in human eosinophils by activating the cannonical β(2)-receptor-adenylyl cyclase-cAMP-protein kinase A pathway.

    Hypereosinophilic syndrome is characterized by idiopathic eosinophilia in the peripheral blood and multiorgan dysfunction secondary to mature eosinophil infiltration. It is essential to diagnose myocardial involvement in the early stage of the disease when active myocarditis due to cardiotoxic substances from eosinophils is still taking place, but clinical tools for the diagnosis of myocardial lesions in patients without overt cardiac dysfunction are not yet available. We present a case of successful detection of myocarditis due to hypereosinophilic syndrome by gadolinium-diethylenetriaminepentaascetic acid (Gd-DTPA) enhanced magnetic resonance imaging (MRI).

    Eosinophilic esophagitis (EE) is a relatively new, chronic, TH 2-type allergic inflammation of the esophagus. EE occurs more frequently in men. Allergic diseases such as asthma or atopic dermatitis are present in 50-70 % of patients or their relatives. In adults, the most common presenting symptom of EE is dysphagia, with or without food bolus impaction. Endoscopic findings of EE include mucosal furrows, corrugated or concentric rings or ridges in the esophagus ("feline esophagus"), with or without tiny whitish exudates. The diagnosis is confirmed by the observation of high counts of eosinophils in the esophageal epithelium (at least 24 /HPF). The cornerstones of medical therapy are either topical or systemic corticosteroids. Additional therapies included leukotriene receptor antagonists (montelukast) and IL-5 blockers (Mepolizumab). Complications of EE such as esophageal strictures should be carefully dilated using either bougies or a balloon. Currently it is still not known whether the late complications of EE can be prevented by the use of anti-inflammatory agents and this can only be demonstrated through further long-term follow-up studies.

    Full Text Available Abstract Eosinophil granulocytes reside in respiratory mucosa including lungs, in the gastro-intestinal tract, and in lymphocyte associated organs, the thymus, lymph nodes and the spleen. In parasitic infections, atopic diseases such as atopic dermatitis and asthma, the numbers of the circulating eosinophils are frequently elevated. In conditions such as Hypereosinophilic Syndrome (HES circulating eosinophil levels are even further raised. Although, eosinophils were identified more than hundred years ago, their roles in homeostasis and in disease still remain unclear. The most prominent feature of the eosinophils are their large secondary granules, each containing four basic proteins, the best known being the eosinophil cationic protein (ECP. This protein has been developed as a marker for eosinophilic disease and quantified in biological fluids including serum, bronchoalveolar lavage and nasal secretions. Elevated ECP levels are found in T helper lymphocyte type 2 (atopic diseases such as allergic asthma and allergic rhinitis but also occasionally in other diseases such as bacterial sinusitis. ECP is a ribonuclease which has been attributed with cytotoxic, neurotoxic, fibrosis promoting and immune-regulatory functions. ECP regulates mucosal and immune cells and may directly act against helminth, bacterial and viral infections. The levels of ECP measured in disease in combination with the catalogue of known functions of the protein and its polymorphisms presented here will build a foundation for further speculations of the role of ECP, and ultimately the role of the eosinophil.

    Full Text Available Recent advances in the treatment and management of asthma have suggested that leukotriene (LT receptor antagonists may be very beneficial as a second generation therapy with steroid-sparing properties and negligible side effects. These agents have shown interesting effects on peripheral blood and sputum eosinophils. A major contributor to the damage in the airway of asthmatic patients is the eosinophil, which, upon activation, releases a battery of granule-associated cytotoxic, cationic proteins, including the major basic protein and eosinophil peroxidase, and membrane-derived de novo-synthesized bioactive lipid mediators, including LTC4, LTD4 and LTE4, as well as platelet activating factor. These products have deleterious effects on the airway tissue including mucosal and smooth muscle layers. Accumulating evidence suggests that these agents may also influence the accumulation and maintenance of eosinophilic responses at the site of inflammation. This article reviews the possible anti-inflammatory mode of action of these therapies. It also discusses where there may be a gap in the knowledge regarding the potential direct and indirect effects of LT modifiers on eosinophil function and recruitment.

    2015-12-01

    Eosinophilic otitis media (EOM) is a type of intractable otitis media that occurs mainly in patients with bronchial asthma (BA). In 2011, the diagnostic criteria for EOM were established. EOM is characterized by the presence of a highly viscous yellowish effusion containing eosinophils and immunoglobulin E (IgE), eosinophil chemoattractants, such as eosinophil cationic protein, interleukin-5, and eotaxin. Local sensitization against foreign agents such as fungi or bacteria (e.g., Staphylococcus aureus) may result in local IgE production in the middle ear and may be responsible for the severity of EOM. The clinical features of EOM closely resemble localized eosinophilic granulomatosis polyangiitis, therefore it is necessary to be vigilant to the symptoms of mononeuritis, polyneuritis, and skin purpura during diagnosis. Standard treatment for EOM is the instillation of triamcinolone acetonide into the mesotympanum. However, severe cases exhibiting strong inflammation and otorrhea are not easily controlled with antibiotics and/or corticosteroids. We proposed the introduction of a severity score to evaluate the severity of EOM. This score correlated with local IgE levels in middle ear effusion. Clinically, the risk factors associated with this severity score were body mass index, and the duration of bronchial asthma (from the onset of BA to the age of the first consultation of otitis media to our hospital). We emphasize that early diagnosis and adequate treatment are vital in preventing progressive and sudden hearing loss resulting from EOM.

    Full Text Available Treg cells play a crucial role in immune tolerance, but mechanisms that induce Treg cells are poorly understood. We here have described eosinophils in lamina propria (LP that displayed high aldehyde dehydrogenase (ALDH activity, a rate-limiting step during all-trans retinoic acid (ATRA synthesis, and expressed TGF-β1 mRNA and high levels of ATRA. Co-incubation assay confirmed that LP eosinophils induced the differentiation of naïve T cells into Treg cells. Differentiation promoted by LP eosinophils were inhibited by blocked either TGF-β1 or ATRA. Peripheral blood (PB eosinophils did not produce ATRA and could not induce Treg differentiation. These data identifies LP eosinophils as effective inducers of Treg cell differentiation through a mechanism dependent on TGF-β1 and ATRA.

    Full Text Available OBJECTIVE: Biological evidence suggests that inflammation might induce type 2 diabetes (T2D, and epidemiological studies have shown an association between higher white blood cell count (WBC and T2D. However, the association has not been systematically investigated. RESEARCH DESIGN AND METHODS: Studies were identified through computer-based and manual searches. Previously unreported studies were sought through correspondence. 20 studies were identified (8,647 T2D cases and 85,040 non-cases. Estimates of the association of WBC with T2D were combined using random effects meta-analysis; sources of heterogeneity as well as presence of publication bias were explored.

We assessed the impact of confounding in EPIC-Norfolk study and found that the age and sex adjusted HR of 2.19 (95% CI: 1.74; 2.75 was attenuated to 1.82 (95% CI: 1.45; 2.29 after further accounting for smoking, T2D family history, physical activity, education, BMI and waist circumference. CONCLUSIONS: A raised WBC is associated with higher risk of T2D. The presence of publication bias and failure to control for all potential confounders in all studies means the observed association is likely an overestimate.

    AIM: To determine the expressions of cysteinyl leukotriene receptors, CysLT1 and CysLT2, in airway eosinophilic inflammation of OVA-induced asthmatic mice and the modulation by montelukast, a CysLT1 receptor antagonist.METHODS: Asthma model was induced by chronic exposure to ovalbumin (OVA) in C57BL/6 mice. The eosinophils in bronchoalveolar lavage (BAL) fluid and lung tissues were counted, IL-5 level in BAL fluid was measured,and CysLT1 and CysLT2 receptor mRNA expressions were detected by semi-quantitative RT-PCR. RESULTS:Montelukast (6 mg/kg, once per day for 20 d) significantly suppressed the increased eosinophils in BAL fluid and lung tissue, and increased IL-5 level in BAL fluid in OVA challenged mice. OVA challenge increased CysLT1 but decreased CysLT2 receptor mRNA expression. Montelukast inhibited the increased CysLT1 but not the reduced CysLT2 expression after OVA challenge. CONCLUSION: CysLT receptors are modulated immunologically, and montelukast inhibits up-regulation of CysLT1 receptor and airway eosinophilic inflammation in asthmatic mice.

    Eosinophilic gastroenteritis (EG) is an inflammation of the digestive tract that is characterized by eosinophilic infiltration. There are no specific symptoms, and are related to the layer in which eosinophilic infiltration is observed. A 69-year-old Japanese man presented to our hospital with a history of general malaise, diarrhea, and dysgeusia. Esophagogastroduodenoscopy showed reddish elevated lesions that were edematous all over the gastric mucosa. In addition, three tumors were also observed. The biopsies of the reddish elevated mucosa revealed eosinophilic infiltration and tubular adenocarcinoma from the tumors. Colonoscopy showed abnormal reddish elevated mucosa. The biopsies from the reddish elevated mucosa showed eosinophilic infiltration. From the abdominal contrast computed tomography scan, tumor stain was seen in the anterior wall of the gastric body. No ascites, intestinal wall thickening, or lymph node swelling were found. A slight elevation in the serum immunoglobulin E (IgE), 480 IU/ml, was found from the laboratory test results; other laboratory results were within normal limits including the number of peripheral eosinophils. No specific allergen was found from the multiple antigen simultaneous test and from the skin patch test. The parasitic immunodiagnosis was negative. He was diagnosed with EG associated with gastric cancer and underwent total gastrectomy, regional lymph node dissection with reconstruction by a Roux-en-Y method. He was prescribed prednisolone after the operation and showed a good clinical response. There are many case reports on EG, but none of them were associated with cancer. We encountered a case of EG associated with multiple gastric cancer; the patient underwent total gastrectomy.

    Full Text Available Dengue often presents with non-specific clinical signs, and given the current paucity of accurate, rapid diagnostic laboratory tests, identifying easily obtainable bedside markers of dengue remains a priority. Previous studies in febrile Asian children have suggested that the combination of a positive tourniquet test (TT and leucopenia can distinguish dengue from other febrile illnesses, but little data exists on the usefulness of these tests in adults or in the Americas. We evaluated the diagnostic accuracy of the TT and leucopenia (white blood cell count <5000/mm(3 in identifying dengue as part of an acute febrile illness (AFI surveillance study conducted in the Emergency Department of Saint Luke's Hospital in Ponce, Puerto Rico. From September to December 2009, 284 patients presenting to the ED with fever for 2-7 days and no identified source were enrolled. Participants were tested for influenza, dengue, leptospirosis and enteroviruses. Thirty-three (12% patients were confirmed as having dengue; 2 had dengue co-infection with influenza and leptospirosis, respectively. An infectious etiology was determined for 141 others (136 influenza, 3 enterovirus, 2 urinary tract infections, and 110 patients had no infectious etiology identified. Fifty-two percent of laboratory-positive dengue cases had a positive TT versus 18% of patients without dengue (P<0.001, 87% of dengue cases compared to 28% of non-dengue cases had leucopenia (P<0.001. The presence of either a positive TT or leucopenia correctly identified 94% of dengue patients. The specificity and positive predictive values of these tests was significantly higher in the subset of patients without pandemic influenza A H1N1, suggesting improved discriminatory performance of these tests in the absence of concurrent dengue and influenza outbreaks. However, even during simultaneous AFI outbreaks, the absence of leucopenia combined with a negative tourniquet test may be useful to rule out dengue.

    The aim of this study was to compare the effect of an intermittent intense aerobic exercise session and a resistance exercise session on blood cell counts and oxidative stress parameters in middle-aged women. Thirty-four women were selected and divided into three groups: RE group (performing 60 min of resistance exercises, N = 12), spinning group (performing 60 min of spinning, N = 12), and control group (not exercising regularly, N = 10). In both exercise groups, lymphocytes and monocytes decreased after 1-h recuperation (post-exercise) compared to immediately after exercise (P < 0.05). Immediately after exercise, in both exercised groups, a significant increase in TBARS (from 16.5 ± 2 to 25 ± 2 for the spinning group and from 18.6 ± 1 to 28.2 ± 3 nmol MDA/mL serum for the RE group) and protein carbonyl (from 1.0 ± 0.3 to 1.6 ± 0.2 for the spinning group and from 0.9 ± 0.2 to 1.5 ± 0.2 nmol/mg protein for the RE group) was observed (P < 0.05). A decrease in antioxidant activities (non-protein sulfhydryl, superoxide dismutase, catalase) was also demonstrated with a negative correlation between damage markers and antioxidant body defenses (P < 0.05). These results indicate that an acute bout of intermittent or anaerobic exercise induces immune suppression and increases the production of reactive oxygen species, causing oxidative stress in middle-aged and trained women. Furthermore, we demonstrated that trained women show improved antioxidant capacity and lower oxidative damage than sedentary ones, demonstrating the benefits of chronic regular physical activity.

    Molecular and cellular markers associated with malignant disease are frequently identified in healthy individuals. The relationship between these markers and clinical disease is not clear, except where a neoplastic cell population can be identified as in myeloma/monoclonal gammopathies of undetermined significance (MGUS). We have used the distinctive phenotype of chronic lymphocytic leukemia (CLL) cells to determine whether low levels of these cells can be identified in individuals with normal complete blood counts. CLL cells were identified by 4-color flow cytometric analysis of CD19/CD5/CD79b/CD20 expression in 910 outpatients over 40 years old. These outpatients were age- and sex-matched to the general population with normal hematologic parameters and no evident history of malignant disease. CLL phenotype cells were detectable in 3.5% of individuals at low level (median, 0.013; range, 0.002- 1.458 x 10(9) cells/L), and represented a minority of B lymphocytes (median, 11%; range, 3%-95%). Monoclonality was demonstrated by immunoglobulin light-chain restriction in all cases with CLL phenotype cells present and confirmed in a subset of cases by consensus-primer IgH-polymerase chain reaction. As in clinical disease, CLL phenotype cells were detected with a higher frequency in men (male-to-female ratio, 1.9:1) and elderly individuals (2.1% of 40- to 59-year-olds versus 5.0% of 60- to 89-year-olds, P =.01). The neoplastic cells were identical to good-prognosis CLL, being CD5+23+20(wk)79b(wk)11a(-)22(wk)sIg(wk)CD38-, and where assessed had a high degree (4.8%-6.6%) of IgH somatic hypermutation. The monoclonal CLL phenotype cells present in otherwise healthy individuals may represent a very early stage of indolent CLL and should be useful in elucidating the mechanisms of leukemogenesis.

    Current National Comprehensive Cancer Network guidelines for breast cancer staging include pre-treatment complete blood count (CBC) and liver function tests (LFT) to screen for occult metastatic disease. To date, the relevance of these tests in detecting metastatic disease in asymptomatic women with early-stage breast cancer (Stage I/II) has not been demonstrated. Although chest x-rays are no longer recommended in the NCCN guidelines, many centers continue to include this imaging as part of their screening process. We aim to determine the clinical and financial impact of these labs and x-rays in the evaluation of early-stage breast cancer patients. A single institution IRB-approved retrospective chart review was conducted of patients with biopsy-proven invasive breast cancer treated from January 1, 2005–December 31, 2009. We collected patient demographics, clinical and pathologic staging, chest x-ray, CBC, and LFT results at the time of referral. Patients were stratified according to radiographic stage at the time of diagnosis. We obtained Medicare reimbursement fees for cost analysis. From 2005 to 2009, 1609 patients with biopsy-proven invasive breast cancer were treated at our institution. Of the 1082 patients with radiographic stage I/II disease, 27.3 % of patients had abnormal CBCs. No additional testing was performed to evaluate these abnormalities. In the early-stage population, 24.7 % of patients had elevated LFTs, resulting in 84 additional imaging studies. No metastatic disease was detected. The cost of CBC, LFTs and chest x-rays was $110.20 per patient, totaling $106,410.99. Additional tests prompted by abnormal results cost $58,143.30 over the five-year period. We found that pre-treatment CBCs, LFTs, and chest x-rays did not improve detection of occult metastatic disease but resulted in additional financial costs. Avoiding routine ordering of these tests would save the US healthcare system $25.7 million annually.

    Background A few recent studies have reported that inflammation is associated with the prognosis of acute aortic dissection (AD).There is,however,no systemic investigation regarding the role of plasma C-reactive protein (CRP) and white blood cell (WBC) levels in predicting in-hospital clinical events of acute type AAD.Methods The levels of high-sensitivity CRP and WBC counts were systemically determined after admission in 36 patients with acute type A AD.The variations of plasma CRP and WBC levels in different time windows (admission,1,2,3,4,6,8 days) in patients with acute type A AD were analyzed between patients with events and without events.Results During hospitalization,five patients died,and increased levels of CRP and WBC were found in patients died with acute type A AD compared with patients survived (P <0.01,respectively).Medical treatment may significantly decrease inflammatory response in survived patients with acute type A AD.Additionally,patients with complication of pleural effusion showed higher CRP and WBC levels (P=0.046,P=0.018,respectively).Lower WBC levels were found in survived patients treated medically (P=0.001).Moreover,mean CRP and WBC levels had positive correlations with aortic diameter (r=0.364,P=0.000;r=0.333,P=0.000,respectively) and age (r=0.270,P=0.000,respectively),while negative correlations with the time from onset of symptoms to hospital admission (r=-0.229,P=0.000,r=-0.200,P=0.002,respectively).Univariate analysis showed that age ≥65 years,CRP ≥12.05 mg/L,WBC ≥12.16×109/L,aortic diameter ≥48mm,pleural effusion and diastolic blood pressure ≥105 mmHg were associated with hospital mortality.While CRP ≥12.05 mg/L,WBC ≥12.16×109/L,aortic diameter ≥48 mm were strongly associated with hospital mortality in multiple Logistic regression analysis.Conclusions The results suggested that CRP and WBC were preferred markers for predicting the clinical events in patients with acute type A AD,especially death during

    A retrospective study of banked sera from 19 cats with the eosinophilic granuloma complex revealed that 68% of affected cats had circulating antibodies to components of normal cat epithelium. Seemingly, the eosinophilic granuloma complex of cats may be an autoimmune disease; however, epidermal damage caused by the eosinophilic granuloma complex may release altered self-antigens to which the cat's immune system responds.

    A knowledge of the limitations of automated platelet counting is essential for the effective care of thrombocytopenic patients and management of platelet stocks for transfusion. For this study, 29 external quality assessment specimen pools with platelet counts between 5 and 64 × 10(9)/L were distributed to more than 1,100 users of 23 different hematology analyzer models. The same specimen pools were analyzed by the international reference method (IRM) for platelet counting at 3 reference centers. The IRM values were on average lower than the all-methods median values returned by the automated analyzers. The majority (~67%) of the automated analyzer results overestimated the platelet count compared with the IRM, with significant differences in 16.5% of cases. Performance differed between analyzer models. The observed differences may depend in part on the nature of the survey material and analyzer technology, but the findings have implications for the interpretation of platelet counts at levels of clinical decision making.

    Full Text Available Eosinophilic granulomatosis with polyangiitis (EGPA is a multisystemic disorder, belonging to the small vessel ANCA-associated vasculitis, defined as a eosinophil-rich and necrotizing granulomatous inflammation often involving the respiratory tract, and necrotizing vasculitis predominantly affecting small to medium-sized vessels, associated with asthma and eosinophilia. EGPA pathogenesis is not well known: HLA-DRB1*04 and *07, HLA-DRB4 and IL10.2 haplotype of the IL-10 promoter gene are the most studied genetic determinants. Among the acquired pathogenetic factors, the exposure to different allergens, infections, vaccinations, drugs and silica exposure have been involved.Eosinophils are the most characteristic cells in EGPA and different studies have demonstrated their role as effector and immunoregulatory cells.EGPA is considered a disease with a prevalent activation of the Th2 cellular-mediated inflammatory response but also humoral immunity plays an important role. A link between B and T inflammatory responses may explain different disease features. EGPA typically develops into three sequential phases: the allergic phase, distinguished by the occurrence of asthma, allergic rhinitis and sinusitis, the eosinophilic phase, in which the main pathological finding is the eosinophilic organ infiltrations (e.g. lungs, heart and gastrointestinal system and the vasculitic phase, characterized by purpura, peripheral neuropathy and constitutional symptoms.ANCA (especially pANCA anti-MPO are present in 40-60% of the patients. An elevation of IgG4 is frequently found. Corticosteroids and cyclophosphamide are classically used for remission induction, while azathioprine and methotrexate are the therapeutic options for remission maintenance. B-cell depletion with rituximab has shown promising results for remission induction.

    AIM: To look at the relationship between eosinophilic oesophagitis(EO) and food bolus impaction in adults. METHODS: We retrospectively analysed medical records of 100 consecutive patients who presented to our hospital with oesophageal food bolus obstruction(FBO) between 2012 and 2014. In this cohort, 96 were adults(64% male), and 4 paediatric patients were excluded from the analysis as our centre did not have paediatric gastroenterologists. Eighty-five adult patients underwent emergency gastroscopy. The food bolus was either advanced into the stomach using the push technique or retrieved using a standard retrieval net. Biopsies were obtained in 51 patients from the proximal and distal parts of the oesophagus at initial gastroscopy. All biopsy specimens were assessed and reviewed by dedicated gastrointestinal pathologists at the Department of Pathology, University Hospital Geelong. The diagnosis of EO was defined and established by the presence of the following histological features:(1) peak eosinophil counts > 20/hpf;(2) eosinophil microabscess;(3) superficial layering of eosinophils;(4) extracellular eosinophil granules;(5) basal cell hyperplasia;(6) dilated intercellular spaces; and(7) subepithelial or lamina propria fibrosis. The histology results of the biopsy specimens were accessed from the pathology database of the hospital and recorded for analysis. RESULTS: Our cohort had a median age of 60. Seventeen/51(33%) patients had evidence of EO on biopsy findings. The majority of patients with EO were male(71%). Classical endoscopic features of oesophageal rings, furrows or white plaques and exudates werefound in 59% of patients with EO. Previous episodes of FBO were present in 12/17 patients and 41% had a history of eczema, hay fever or asthma. Reflux oesophagitis and benign strictures were found in 20/34 patients who did not have biopsies. CONCLUSION: EO is present in approximately one third of patients who are admitted with FBO. Biopsies should be performed

    Objective To investigate the changes of fetal nucleated red blood cells count (FNRBC) in peripheral blood of pregnant women with different pregnancy complications, such as hypertensive disorders in pregnancy, gestational diabetes mellitus (GDM) and pregnancy with thrombocytopenia. Methods Thirty clinically diagnosed hypertensive disorders in pregnancy patients (12 cases mild preeclampsia, 12 cases severe preeclampsia,6 cases eclampsia),23 cases GDM patients (13 cases blood sugar control ideal and without hypoglycemia or ketosis,10 cases whose blood sugar control was not ideal and ever occurred hypoglycemia or ketosis) and 18 cases pregnancy with thrombocytopenia patients were analyzed in this study. Twenty cases normal pregnant women were taken as control at the same time. The peripheral blood of women in each group was obtained to count FNBRC and perform Wright-Giemsa stain after single density gradient centrifugation. Results There were significant differences in FNRBC number in peripheral blood of mild preeclampsia patients, severe preeclampsia patients and eclampsia patients compared with normal pregnant women in control group (P0. 05). Conclusion The FNRBC number of preeclampsia patients,eclampsia patients and GDM patients increase; moreover, the increase of FNRBC number in maternal peripheral blood is more obvious when illness is aggravated. The results suggest that increasing of FNRBC number can indicate aggravation of pregnancy complications and threat fetal life. Doctors should take effective interventions actively, and terminate pregnancy if necessary.%目的 探讨妊娠期高血压疾病、妊娠期糖尿病、妊娠合并血小板减少症时,母血中胎儿有核红细胞(fetal nucleated red blood cell,FNRBC)数量的变化.方法 选择临床确诊的妊娠期高血压疾病患者30例(其中子痫前期轻度12例,子痫前期重度12例,子痫6例),妊娠期糖尿病患者23例(其中血糖控制理想无低血糖或酮症发生13例,血糖控制

  5. Mitochondria in the Center of Human Eosinophil Apoptosis and Survival

    2014-03-01

    Full Text Available Eosinophils are abundantly present in most phenotypes of asthma and they contribute to the maintenance and exacerbations of the disease. Regulators of eosinophil longevity play critical roles in determining whether eosinophils accumulate into the airways of asthmatics. Several cytokines enhance eosinophil survival promoting eosinophilic airway inflammation while for example glucocorticoids, the most important anti-inflammatory drugs used to treat asthma, promote the intrinsic pathway of eosinophil apoptosis and by this mechanism contribute to the resolution of eosinophilic airway inflammation. Mitochondria seem to play central roles in both intrinsic mitochondrion-centered and extrinsic receptor-mediated pathways of apoptosis in eosinophils. Mitochondria may also be important for survival signalling. In addition to glucocorticoids, another important agent that regulates human eosinophil longevity via mitochondrial route is nitric oxide, which is present in increased amounts in the airways of asthmatics. Nitric oxide seems to be able to trigger both survival and apoptosis in eosinophils. This review discusses the current evidence of the mechanisms of induced eosinophil apoptosis and survival focusing on the role of mitochondria and clinically relevant stimulants, such as glucocorticoids and nitric oxide.

    The purpose of this study was to investigate the ultrastructural appearance of flame figures, reported to comprise a mixture of degenerate collagen and degranulated eosinophils, in feline eosinophilic granuloma complex (EGC). Skin specimens from eight cats with EGC and from two clinically healthy cats were examined by transmission electron microscopy. Flame figures appeared to comprise ultrastructurally normal collagen fibrils separated by oedema and surrounded by large numbers of degranulating eosinophils. Longitudinal sections of collagen fibrils displayed the characteristic cross-striation of normal dermal collagen. Feline eosinophils, analogous to human eosinophils, degranulated both by cytolysis and piecemeal degranulation. The results of this study suggest that flame figures form in feline EGC due to eosinophil recruitment and degranulation, and that collagen fibres are partially disrupted but collagen fibrils are not damaged. These findings suggest that eosinophil accumulation and the release of granule contents represent the primary events in feline EGC.

    Eosinophils are now recognized as multifunctional leukocytes that provide critical homeostatic signals to maintain other immune cells and aid tissue repair. Paradoxically, eosinophils also express an armory of granule-localized toxins and hydrolases believed to contribute to pathology in inflammatory disease. How eosinophils deliver their supporting functions while avoiding self-inflicted injury is poorly understood. We have demonstrated that cystatin F (CF) is a critical survival factor for eosinophils. Eosinophils from CF null mice had reduced lifespan, reduced granularity, and disturbed granule morphology. In vitro, cysteine protease inhibitors restored granularity, demonstrating that control of cysteine protease activity by CF is critical for normal eosinophil development. CF null mice showed reduced pulmonary pathology in a model of allergic lung inflammation but also reduced ability to combat infection by the nematode Brugia malayi. These data identify CF as a "cytoprotectant" that promotes eosinophil survival and function by ensuring granule integrity. VIDEO ABSTRACT.

    ECRS is different from non-ECRS in terms of many clinical features: symptom appearance, occurrence site of nasal polyps, CT scan findings, the histology of nasal polyps, blood examination findings, clinical course after surgery, and co-morbid asthma, etc. In this review, we describe these clinical features and mention how to make a clinical diagnosis of ECRS as well as how to treat it. Finally, we discuss the pathophysiology of ECRS. The concept of ECRS in Japan would be applicable for CRSwNP in other countries including Europe and the United States.

    A wide range of patient health data is recorded in Electronic Health Records (EHR). This data includes diagnosis, surgical procedures, clinical laboratory measurements, and medication information. Together this information reflects the patient's medical history. Many studies have efficiently used this data from the EHR to find associations that are clinically relevant, either by utilizing International Classification of Diseases, version 9 (ICD-9) codes or laboratory measurements, or by designing phenotype algorithms to extract case and control status with accuracy from the EHR. Here we developed a strategy to utilize longitudinal quantitative trait data from the EHR at Geisinger Health System focusing on outpatient metabolic and complete blood panel data as a starting point. Comprehensive Metabolic Panel (CMP) as well as Complete Blood Counts (CBC) are parts of routine care and provide a comprehensive picture from high level screening of patients' overall health and disease. We randomly split our data into two datasets to allow for discovery and replication. We first conducted a genome-wide association study (GWAS) with median values of 25 different clinical laboratory measurements to identify variants from Human Omni Express Exome beadchip data that are associated with these measurements. We identified 687 variants that associated and replicated with the tested clinical measurements at p<5×10-08. Since longitudinal data from the EHR provides a record of a patient's medical history, we utilized this information to further investigate the ICD-9 codes that might be associated with differences in variability of the measurements in the longitudinal dataset. We identified low and high variance patients by looking at changes within their individual longitudinal EHR laboratory results for each of the 25 clinical lab values (thus creating 50 groups - a high variance and a low variance for each lab variable). We then performed a PheWAS analysis with ICD-9 diagnosis codes

    Eosinophilic esophagitis (EE) is the most frequent condition found in a group of gastrointestinal disorders called eosinophilic gastrointestinal diseases.The hypothetical pathophysiological mechanism is related to a hypersensitivity reaction.Gastroesophageal reflux disease-like complaints not ameliorated by acid blockade or occasional symptoms of dysphagia or food impaction are likely presentations of EE.Due to its unclear pathogenesis and unspecific symptoms,it is difficult to diagnose EE without a strong suspicion.Although histological criteria are necessary to diagnosis EE,there are some characteristic endoscopic features.We present the case of a healthy 55-year-old woman with dysphagia and several episodes of esophageal food impaction over the last six months.This case report stresses the most distinguishing endoscopic findings-mucosa rings,white exudative plaques and linear furrows-that can help in the prompt recognition of this condition.

    We examined 11 pediatric patients with eosinophilic esophagitis with a tardy diagnosis. The symptoms were initially thought to be related to other diseases, leading to the use of inadequate therapeutic approaches. The patients were between 3 and 17 years old (mean 7.8 ± 3.8 years), and 8 of the patients were male. Common symptoms included abdominal pain, regurgitation, difficulty in gaining weight, vomiting, dysphagia, and coughing. The mean age for the onset of symptoms was 4.3 ± 2.9 years. Endoscopic findings included normal mucosa in five (45%) patients, thickening of the mucosa with longitudinal grooves in three (27%), erosive esophagitis in two (18%), and a whitish stippling in one (9%) patient. Treatment included the use of a topical corticosteroid for 10 patients. In eight (73%) cases, the treatment made the symptoms disappear. Ten patients underwent histopathological management after treatment, with a decrease in the number of eosinophils. PMID:24106430

    Increased FDG uptake in the bone marrow has been reported in patients taking erythropoietin or granulocyte-colony stimulating factor (G-CSF). The aim of this study is to investigate the correlation between F-18 FDG uptake in the bone marrow and bone marrow finding, hematological parameters. Twenty patients who had diffuse FDG uptake at the bone marrow and received hematological examinations, bone marrow biopsy within 10 days before or after PET/CT were enrolled in this study. Among them, 11 patients were excluded; 4 patients received G-CSF or erythropoietin before PET/CT. Seven patients showed definite pathology in a bone marrow biopsy. The parameters included the measurement of WBC, hemoglobin, platelet and cellularity of the bone marrow. Bone marrow FDG uptake was correlated with a low hemoglobin but not WBC, platelet. Histopathologic findings in marrow biopsies were various: normal finding (n=3), hyperplasia of granulocytic cells (n=2), eosinophilic hyperplasia (n=1), reactive lymphoid nodules (n=1), hypercelluar marrow (n=1), hypocelluar marrow (n=1). All patients except two, showed normal marrow celluarity. FDG uptake by bone marrow correlated with anemia but not WBC, platelet, bone marrow cellularity.

    Full Text Available Timothy Williamson supports the thesis that every possible entity necessarily exists and so he needs to explain how a possible son of Wittgenstein’s, for example, exists in our world:he exists as a merely possible object (MPO, a pure locus of potential. Williamson presents a short argument for the existence of MPOs: how many knives can be made by fitting together two blades and two handles? Four: at the most two are concrete objects, the others being merely possible knives and merely possible objects. This paper defends the idea that one can avoid reference and ontological commitment to MPOs. My proposal is that MPOs can be dispensed with by using the notion of rules of knife-making. I first present a solution according to which we count lists of instructions - selected by the rules - describing physical combinations between components. This account, however, has its own difficulties and I eventually suggest that one can find a way out by admitting possible worlds, entities which are more commonly accepted - at least by philosophers - than MPOs. I maintain that, in answering Williamson’s questions, we count classes of physically possible worlds in which the same instance of a general rule is applied.

  2. Assumed white blood cell count of 8,000 cells/μL overestimates malaria parasite density in the Brazilian Amazon.

    Directory of Open Access Journals (Sweden)

    Eduardo R Alves-Junior

    Full Text Available Quantification of parasite density is an important component in the diagnosis of malaria infection. The accuracy of this estimation varies according to the method used. The aim of this study was to assess the agreement between the parasite density values obtained with the assumed value of 8,000 cells/μL and the automated WBC count. Moreover, the same comparative analysis was carried out for other assumed values of WBCs. The study was carried out in Brazil with 403 malaria patients who were infected in different endemic areas of the Brazilian Amazon. The use of a fixed WBC count of 8,000 cells/μL to quantify parasite density in malaria patients led to overestimated parasitemia and resulted in low reliability when compared to the automated WBC count. Assumed values ranging between 5,000 and 6,000 cells/μL, and 5,500 cells/μL in particular, showed higher reliability and more similar values of parasite density when compared between the 2 methods. The findings show that assumed WBC count of 5,500 cells/μL could lead to a more accurate estimation of parasite density for malaria patients in this endemic region.

    Objective: To evaluate the necessity of weekly monitoring by means of leukocyte and platelet counts of patients with head and neck, chest, and pelvis cancer submitted to conventional radiotherapy. Materials and methods: A hundred and one adult patients with cancer of head and neck (n = 11), chest (n = 35) and pelvis (n = 55), submitted to radiotherapy were assessed by means of leukocyte and platelet counts on a weekly basis, with a comparison between the results before and during the treatment and in correlation with the area treated, patient's sex and age group. Results: The most significant decrease in leukocytes was observed in the fourth week, when lymphocytes, total leukocytes, neutrophils, monocytes and platelets presented a decrease of 53.5%, 26.8%, 19.4%, 22.2% and 14.6%, respectively, in comparison with the values found before the beginning of the therapy. Geometric means for pelvis during the treatment were lower than those for chest, and head and neck. Lymphocytes demonstrated to be more sensitive to radiation therapy. No alteration was found in leukocyte or platelet counts in correlation with patients' sex or age. Conclusion: Based on the results of the present study, weekly leukocyte and platelet counts do not seem to be useful in the assessment patients submitted to conventional radiotherapy for localized cancer.

    Fructans are dietary fibers with beneficial effects on the gastrointestinal physiology and offer a promising approach for the treatment of some metabolic disorders associated with obesity. In vitro and in vivo studies were developed to test the safety of fructans obtained from Agave tequilana Weber var. azul. Additionally, an in vivo experiment using a diet-induced obesity model was performed to compare the effect of agave fructans with different degree of polymerization (DP) profiles: agave fructans with DP > 10 (LcF), agave FOS with DP agave fructans with and without demineralization (dTF, TF) versus commercial chicory fructans (OraftiSynergy1™) on the body weight change, fat, total cholesterol, triglycerides and count of fecal Lactobacillus spp. and Bifidobacterium spp. Results showed that A. tequilana fructans were not mutagenic and were safe even at a dose of 5 g per kg b.w. Obese mice that received ScF showed a significant decrease in body weight gain, fat tissue and total cholesterol without increasing the count of fecal Bifidobacteria. Whereas, obese mice that received LcF and TF showed decreased triglycerides and an increased count of fecal Bifidobacteria. Interestingly, although obese mice that received dTF did not show changes in body weight gain, fat tissue, total cholesterol or triglycerides, they showed an increase in the count of Bifidobacteria. These results demonstrate that both the degree of polymerization and the demineralization process can influence the biological activity of agave fructans.

    In cats, the most common eosinophilic dermatoses are feline miliary dermatitis and eosinophilic granuloma complex. The most commonly identified underlying cause is a hypersensitivity reaction. Few cases of familial forms of eosinophilic dermatoses are reported in the literature. Two young adult cats from the same litter presented 2 years apart with a severe and chronic fluid or tissue infiltration of the distal part of several limbs. Lesions started on the forelegs and developed on the other ...

    Eosinophils and their products are probably important in the pathophysiology of allergic diseases, such as bronchial asthma, and in host immunity to certain organisms. An association between environmental fungal exposure and asthma has been long recognized clinically. Although products of microorganisms (e.g., lipopolysaccharides) directly activate certain inflammatory cells (e.g., macrophages), the mechanism(s) that triggers eosinophil degranulation is unknown. In this study we investigated whether human eosinophils have an innate immune response to certain fungal organisms. We incubated human eosinophils with extracts from seven environmental airborne fungi (Alternaria alternata, Aspergillus versicolor, Bipolaris sorokiniana, Candida albicans, Cladosporium herbarum, Curvularia spicifera, and Penicillium notatum). Alternaria and Penicillium induced calcium-dependent exocytosis (e.g., eosinophil-derived neurotoxin release) in eosinophils from normal individuals. Alternaria also strongly induced other activation events in eosinophils, including increases in intracellular calcium concentration, cell surface expression of CD63 and CD11b, and production of IL-8. Other fungi did not induce eosinophil degranulation, and Alternaria did not induce neutrophil activation, suggesting specificity for fungal species and cell type. The Alternaria-induced eosinophil degranulation was pertussis toxin sensitive and desensitized by preincubating cells with G protein-coupled receptor agonists, platelet-activating factor, or FMLP. The eosinophil-stimulating activity in Alternaria extract was highly heat labile and had an M(r) of approximately 60 kDa. Thus, eosinophils, but not neutrophils, possess G protein-dependent cellular activation machinery that directly responds to an Alternaria protein product(s). This innate response by eosinophils to certain environmental fungi may be important in host defense and in the exacerbation of inflammation in asthma and allergic diseases.

    Eosinophilic esophagitis (EoE) is a chronic allergic disease characterized by esophageal intraepithelial eosinophils, extracellular eosinophil granule deposition, induced mast cell accumulation, and epithelial cell hyperplasia. However, the processes involved in the development of a number of these characteristics are largely unknown. Herein, we tested the hypothesis whether induced mast cell accumulation in the esophagus has a role in promoting EoE pathogenesis. Accordingly, we induced exper...

    Eosinophilic cholangiopathy is a rare condition characterized by eosinophilic infiltration of the biliary tract and causes sclerosing cholangitis. We report a patient with secondary sclerosing cholangitis with eosinophilic cholecystitis. A 46-year-old Japanese man was admitted to our hospital with jaundice.Computed tomography revealed dilatation of both the intrahepatic and extrahepatic bile ducts, diffuse thickening of the wall of the extrahepatic bile duct, and thickening of the gallbladder wall. Under the diagnosis of lower bile duct carcinoma, he underwent pyloruspreserving pancreatoduodenectomy and liver biopsy.On histopathological examination, conspicuous fibrosis was seen in the lower bile duct wall. In the gallbladder wall, marked eosinophilic infiltration was seen. Liver biopsy revealed mild portal fibrosis. He was diagnosed as definite eosinophilic cholecystitis with sclerosing cholangitis with unknown etiology. The possible etiology of sclerosing cholangitis was consequent fibrosis from previous eosinophilic infiltration in the bile duct. The clinicopathological findings of our case and a literature review indicated that eosinophilic cholangiopathy could cause a condition mimicking primary sclerosing cholangitis (PSC). Bile duct wall thickening in patients (PSC). Bile duct wall thickening in patients with eosinophilic cholangitis might be due to fibrosis of the bile duct wall. Eosinophilic cholangiopathy might be confused as PSC with eosinophilia.

    Full Text Available Eosinophilic enteritis, an increasing recognized condition, is rare and often presents with non-specific symptoms. We report a case of a 46-year old female who presented with acute onset abdominal pain and nausea associated with ascites, small bowel thickening and peripheral eosinophilia. Diagnosis was confirmed by biopsies taken at esophagogastroduodenoscopy demonstrating diffuse infiltration by inflammatory cells, mainly eosinophils. Appropriate therapy was instituted. The patient recovered well and was symptom-free at 1-month follow up. In this report, we discuss the clinical presentation and the diagnostic criteria of the eosinophilic enteritis, and examine the pathophysiological theories and therapeutic strategies. The relevant literature on eosinophilic enteritis is summarized.

    Eosinophils, a constitutive component of the columnar-lined gastrointestinal tract, play an essential role in allergic responses and parasitic infections. The tissue density of these cells also increases in a variety of conditions of uncertain etiology. With the exception of the esophageal squamous epithelium, in which no eosinophils are normally present, the population of normal eosinophils in the remainder of the luminal gut is poorly defined. Therefore, histopathologists must rely on their subjective judgment to determine when a diagnosis of eosinophilic gastritis, enteritis, or colitis should be rendered. Eosinophilic esophagitis is currently the best defined and most studied eosinophilic condition of the digestive tract; therefore, the confidence in accurate diagnosis is increasing. In contrast, the characteristic clinicopathologic features of eosinophilic conditions affecting other parts of the digestive tract remain somewhat elusive. This review was designed to present pathologists with simple and practical information for the biopsy-based histopathologic diagnosis of eosinophilic esophagitis, gastritis, enteritis, and colitis. It was prepared by critically reviewing more than 200 articles on the topic, along with incorporating evidence accumulated through our own collective experience. We anticipate that by increasing pathologists' confidence in reporting these abnormal but often nameless eosinophilic infiltrates, we can help better define and characterize their significance.

  11. Evidence for eosinophil recruitment, leukotriene B4 production and mast cell hyperplasia following Toxocara canis infection in rats

    2011-04-01

    Full Text Available It is well known that eosinophilia is a key pathogenetic component of toxocariasis. The objective of the present study was to determine if there is an association between peritoneal and blood eosinophil influx, mast cell hyperplasia and leukotriene B4 (LTB4 production after Toxocara canis infection. Oral inoculation of 56-day-old Wistar rats (N = 5-7 per group with 1000 embryonated eggs containing third-stage (L3 T. canis larvae led to a robust accumulation of total leukocytes in blood beginning on day 3 and peaking on day 18, mainly characterized by eosinophils and accompanied by higher serum LTB4 levels. At that time, we also noted increased eosinophil numbers in the peritoneal cavity. In addition, we observed increased peritoneal mast cell number in the peritoneal cavity, which correlated with the time course of eosinophilia during toxocariasis. We also demonstrated that mast cell hyperplasia in the intestines and lungs began soon after the T. canis larvae migrated to these compartments, reaching maximal levels on day 24, which correlated with the complete elimination of the parasite. Therefore, mast cells appear to be involved in peritoneal and blood eosinophil infiltration through an LTB4-dependent mechanism following T. canis infection in rats. Our data also demonstrate a tight association between larval migratory stages and intestinal and pulmonary mast cell hyperplasia in the toxocariasis model.

    Full Text Available A 56-year-old woman was referred to our hospital because of dyspnea, wheezing, and a productive cough. Eight years before presentation, bronchial asthma was diagnosed and the patient received inhaled corticosteroids plus antiasthmatic agents (a long-acting inhaled p2-agonist, leukotriene modifiers, and theophylline. Chest radiography showed small diffuse nodular shadows, and a computed tomographic scan showed thickening of the bronchi and bronchioles, with diffuse centrilobular nodules in both lung fields. A blood test and microscopic examination of the bronchoalveolar fluid revealed marked eosinophilia. Transbronchial lung biopsy and transbronchial biopsy showed eosinophilic bronchitis and bronchiolitis. After treatment with oral prednisolone (40 mg daily and inhaled corticosteroids, the symptoms, blood eosinophilia, and radiographic findings improved. Recently, several similar cases of eosinophilic bronchiolitis have been reported. Studies of further cases and elucidation of the pathophysiology of eosinophilic bronchiolitis are necessary to establish a concept for this disease and to determine whether it should be classified as a subtype of bronchial asthma or as a distinct entity.

    Although the etiology of eosinophilic cholecystitis is still obscure, the postulated causes include allergies,parasites, hypereosinophilic syndrome, and eosinophilic gastroenteritis. It is sometimes accompanied by several complications, but a simultaneous onset with pericarditis is very rares. A 28-year-old woman complained of acute right hypocondrial pain and dyspnea associated with systemic eruption. Several imaging modalities revealed acute cholecystitis and pericarditis with massive pericardial effusion. A marked peripheral blood eosinophilia was observed, and the eruption was diagnosed as urticaria. Her serum had a high titer of antibody against Ascaris lumbricoides. Treatment with albendazole drastically improved all clinical manifestations along with normalization of the imaging features and eosinophilia. We report herein a rare case of simultaneous onset of acute cholecystitis and pericarditis associated with a marked eosinophilia caused by parasitic infection.

    2013-06-01

    Angiostrongylus Eosinophilic Meningitis is caused by human infection with larvae of the rat lungworm, Angiostrongylus cantonensis. The clinical presentation includes a spectrum of disease, from meningitis through radiculitis, cranial nerve abnormalities, ataxia, encephalitis, coma, and rarely death. The condition is diagnosed by recognizing the triad of: the clinical syndrome, eosinophils in the cerebrospinal fluid or blood, and exposure history. A history of eating raw or poorly cooked snails is classic, but ingestion of other intermediate hosts or unwashed produce (such as lettuce) harboring hosts is not uncommon. Several serologic tests exist but none has yet been fully validated. There is good evidence that a 2 week course of high dose corticosteroids shortens the duration and severity of symptoms. There is somewhat weaker evidence that albendazole reduces symptoms. The combination of prednisolone and albendazole is being used more commonly for treatment. Some suggestions for future research are given.

    A 61-year-old woman presented with circumscribed eczematous eruptions with maceration, erosions and patchy infiltration in the perineum and inframammary regions. A diagnosis of eosinophilic granuloma (cutaneous histiocytosis X) was established. T lymphocytes from a skin biopsy were grown in vitro for three weeks after which chromosomal studies revealed a break or gap at chromosome 16q22 in 15% of the lymphocytes. The addition of alpha-interferon increased the percentage of affected cells to 28%. T lymphocytes from the patient's blood did not show the defect. The biological significance of the chromosomal defect is uncertain. It has been described before in healthy persons, malignant lymphoma, cold urticaria and IgA deficiency, and mental retardation. It has not been seen in patients with eosinophilic granuloma.

One of these phenotypes is eosinophilic asthma. As the development of eosinophilic inflammation is categorically dependent on the biological activity of Interleukin (IL-5, IL-5 antagonism became an obvious target for therapy in this phenotype. Early trials of monoclonal antibodies targeting the biological activity of IL-5, including reslizumab, mepolizumab, and benralizumab, were performed on asthmatics with no concern for evidence of eosinophilia. These trials were largely unsuccessful. However, during these trials, researchers recognized the need to quantify eosinophilia in asthma subjects in order to identify those asthmatics in whom these medications would be more likely to improve symptoms and lung function. Using biomarkers, such as sputum and blood eosinophilia, recent studies of these medications have shown improvements in blood and sputum eosinophilia, forced expiratory volume in 1 second, and quality of life assessments as well as reducing occurrences of exacerbations. Moving forward, better and less invasive biomarkers of eosinophilia are necessary to ensure that the correct patients are chosen to receive these medications to receive maximal benefit. Keywords

White blood cell count( WBC) ,red blood cell count( RBC) ,hemoglobin(Hb) and blood platelet count( BPC) were detected. Results Among 444 officers and soldiers,WBC,RBC,Hb,BPC were(5.9 ±1.4) × 109/L, (5. 2 ±0.4) × 1012/ L,( 144.4 ±12. l)g/L,(243.9±47.4) X lO'/L respectively. The abnormality detection rates of WBC,RBC, Hb,and BPC were 8. 0% , 17. 6% ,7.5% and 11.7% respectively. RBC was the highest and the higher was WBC and BPC. Each abnormality detection rate of 4 indexes from navy was higher than that of army,but the difference of Hb only had statistical significance ( P < 0. 05). Conclusion The chief indexes of blood count such as WBC,RBC,Hb,and BPC of the officers and 9oldiers can maintain normal level. The measures should be adopted for abnormality detection rate with dynamic status in order to diagnose and treat in time.

    Background Innate and adaptive immune responses change with increasing age and affect the course of diseases. Previous study investigated immunologic alteration in Western nasal polyps (NP) which is mostly eosinophilic. However, there are no reports regarding age-related immune changes of non-eosinophilic NP (NE-NP) which is a predominant subtype in Asian population. Methods A total of 153 subjects, including 20 with control, 63 with chronic rhinosinusitis (CRS) without NP (CRSsNP), and 70 with CRS with NP were enrolled. Age-related changes in computed tomography (CT), cytokines and clinical information were investigated. Tissue samples were analyzed for protein levels of IL-5, IL-17A, IL-23, interferon (IFN)-γ, CCL-11, and CXCL-8, using Luminex immunoassay and for mRNA expression levels of interleukin (IL)-5, IL-17A, IL-23p19, IFN-γ, CCL-11, CXCL-1, CXCL-2, CXCL-8, and CXCR2 by quantitative RT-PCR. Immunohistochemistry (IHC) was performed for the number of inflammatory cells. Results We observed that Lund-Mackay CT scores decreased with age in NE-NP. The number of human neutrophil elastase-positive cells and myeloperoxidase gene expression decreased in older patients with NE-NP, but not in control subjects, CRSsNP, and E-NP. Neutrophil-associated cytokines including IL-17A and IL-23, were negatively correlated with age in NE-NP at the protein and mRNA levels. Additionally, the expression of CXCR2, a receptor for CXCL-1 and CXCL-2, was decreased with age in NE-NP. However, there were no age-related changes in blood neutrophil count, and neutrophil-recruiting chemokines such as CXCL-1, CXCL-2, and CXCL-8. Elderly NE-NP patients showed better endoscopic scores at 12 months after surgery compared with the non-elderly. Conclusion Age-related decline in neutrophil inflammation may favorably affect postoperative results in elderly patients with NE-NP. PMID:26849431

    Eosinophilic esophagitis (EoE) is a chronic immune disease, characterized by a dense eosinophilic infiltrate in the esophagus, leading to bolus impaction and reflux-like symptoms. Traditionally considered a pediatric disease, the number of adult patients with EoE is continuously increasing, with a relatively higher incidence in western countries. Dysphagia and food impaction represent the main symptoms complained by patients, but gastroesophageal reflux-like symptoms may also be present. Esophageal biopsies are mandatory for the diagnosis of EoE, though clinical manifestations and proton pump inhibitors responsiveness must be taken into consideration. The higher prevalence of EoE in patients suffering from atopic diseases suggests a common background with allergy, however both the etiology and pathophysiology are not completely understood. Elimination diets are considered the first-line therapy in children, but this approach appears less effective in adults patients, who often require steroids; despite medical treatments, EoE is complicated in some cases by esophageal stricture and stenosis, that require additional endoscopic treatments. This review summarizes the evidence on EoE pathophysiology and illustrates the safety and efficacy of the most recent medical and endoscopic treatments.

  6. Bone marrow contribution to eosinophilic inflammation

    1997-01-01

    Full Text Available Allergen-induced bone marrow responses are observable in human allergic asthmatics, involving specific increases in eosinophil-basophil progenitors (Eo/B-CFU, measured either by hemopoietic assays or by flow cytometric analyses of CD34-positive, IL-3Ralpha-positive, and/or IL-5-responsive cell populations. The results are consistent with the upregulation of an IL-5-sensitive population of progenitors in allergen-induced late phase asthmatic responses. Studies in vitro on the phenotype of developing eosinophils and basophils suggest that the early acquisition of IL-5Ralpha, as well as the capacity to produce cytokines such as GM-CSF and IL-5, are features of the differentiation process. These observations are consistent with findings in animal models, indicating that allergen-induced increases in bone marrow progenitor formation depend on hemopoietic factor(s released post-allergen. The possibility that there is constitutive marrow upregulation of eosinophilopoiesis in allergic airways disease is also an area for future investigation.

    Proteins from human eosinophils were separated bidimensionally and identified by mass spectrometry (336 spots/bands, 98 different proteins). Of these, 24.7% belonged to the cytoskeleton/migration group. Highly basic proteins (11.3%) were concentrated in the granule-containing cell fraction. We detected novel hyperacidic forms of cofilin-1, profilin-1 and adenylyl cyclase-associated protein, and hyperbasic forms of eosinophil-derived neurotoxin/eosinophil protein X and major basic protein homologue. We also found evidence of the triglycosylation of the heavy chain of eosinophil peroxidase. In addition, through comparative 2D image analysis, spot quantification and MS, it was found that hsc70, actin-capping protein and hyperacidic forms of eosinophil peroxidase heavy chain are overexpressed in cells from birch pollen allergic subjects, at the peak of a season. The link between these findings and an increased cellular antigen-presenting capacity and motility are discussed.

    Full Text Available Celiac disease is a chronic, immune-mediated disorder, characterized by small intestinal inflammation and villous atrophy after the ingestion of gluten by genetically susceptible individuals. Several extraintestinal manifestations have been associated to celiac disease. Eosinophilic esophagitis is a primary disorder of the esophagus characterized by upper gastrointestinal symptoms, absence of gastroesophageal reflux disease and more than 15 eosinophils per high-power field in biopsy specimens. Both celiac disease and eosinophilic esophagitis are caused by aberrant, but distinct, immune responses to ingested antigens and can be responsive to restricted food intake. The aim of this review is to assess whether there is an association between these two pathologies. In the majority of the studies examined, including the studies in pediatric population, the prevalence of eosinophilic esophagitis in subjects with celiac disease was about 10-times that of the general population. We suggest searching for eosinophilic esophagitis in all children undergoing endoscopy for suspicious celiac disease.

    Full Text Available Eosinophilic gastroenteritis is an uncommon condition characterized by focal or diffuse infiltration of eosinophils in the gastrointestinal tract in the absence of secondary causes. The pathogenesis of this condition is not well understood and its clinical presentation depends on the segment and layer of the gastrointestinal tract affected. The definition of eosinophilic gastroenteritis may be difficult, as the normal ranges of eosinophil numbers in normal and abnormal gastric and intestinal mucosa are not standardized. We present the case of a 59-year-old male who came to the hospital with hypovolemic shock and lethargy secondary to severe diarrhea. Laboratory analysis was significant for peripheral eosinophilia, and pathology from both the duodenum and colon showed marked eosinophilic infiltration.

    We recently established a human granulocyte-macrophage colony-stimulating factor (GM-CSF)-dependent cell line (HML) from colony-constituent cells grown by peripheral blood cells of a patient with acute megakaryoblastic leukaemia. The HML cells possessed megakaryocytic features, as determined by cytochemical, electron microscopic and flow cytometric analysis. In the present study we examined the effects of retinoic acid (RA) on the development of HML cells. All-trans-RA, 13-cis-RA and 9-cis-RA at 10(-8) mol/l to 10(-5) mol/l inhibited the GM-CSF-dependent cell growth. Some of the RA-treated cells contained prominent azurophilic granules and were positive for peroxidase. They also reacted with Biebrich scarlet, Luxol fast blue and a monoclonal antibody against eosinophil peroxidase. In addition, exposure to RA increased the frequency and the intensity of major basic protein-positive cells. However, eosinophil-derived neurotoxin and eosinophil cationic protein were not detected or were only detected at a low level in the lysates of the HML cells treated with RA. Although IL-5 alone could not stimulate cell growth, the addition of IL-5 to the cultures containing stem cell factor + all-trans-RA was required for the expression of the eosinophilic phenotype. These results suggest that the HML cell line is a megakaryoblastic cell line with the potential to differentiate into the eosinophilic lineage. HML cells may be a useful model for elucidating the eosinophilic differentiation programme.

    AIM: To produce an antibody against rat eosinophil cationic protein (ECP) and to examine the effects of the antibody in rats with dextran sulfate sodium (DSS)-induced colitis.METHODS: An antibody was raised against rat ECP. Rats were treated with 3% DSS in drinking water for 7 d and received the antibody or normal serum. The colons were exarmined histologically and correlated with clinical symptoms.Immunohistochemistry and Western blot analysis were estimated as a grade of inflammation.RESULTS: The ECP antibody stained the activated eosinophils around the injured crypts in the colonic mucosa.Antibody treatment reduced the severity of colonic ulceration and acute clinical symptoms (diarrhea and/or blood-stained stool). Body weight gain was significantly greater and the colon length was significantly longer in anti-ECP-treated rats than in normal serum-treated rats. Expression of ECP in activated eosinophils was associated with the presence of erosions and inflammation. The number of Ki-67-positive cells in the regenerated surface epithelium increased in anti-ECP-treated rats compared with normal serum-treated rats. Western blot analysis revealed reduced expression of macrophage migration inhibitory factor (MIF) in anti-ECP-treated rats.CONCLUSION: Our results indicate that treatment with ECP antibody, improved DSS-induced colitis in rats, possibly by increasing the regenerative activity of the colonic epithelium and downregulation of the immune response,and suggest that anti-ECP may promote intestinal wound healing in patients with ulcerative colitis (UC).

  16. Interleukin-5 modulates interleukin-8 secretion in eosinophilic inflammation

    1998-01-01

    Full Text Available Serum and BALF (bronchoalveolar lavage fluid IL-8 levels and serum levels were investigated in Tox ocara canis infected guinea-pigs and the role of IL-5 as a modulator of cytokine secretion was studied. Serum levels increased early in infected animals, exceeding control levels 4 h after infection, peaked between days 6 and 18, and continued to exceed control levels after 48 days of infection. Serum and BALF IL-8 levels showed the same profile as blood eosinophilia, increasing 6 days post-infection and peaking between days 18 and 24. Treatment of infected animals with anti-IL-5 Ab suppressed eosinophilia with a parallel increase in blood IL-8 levels, whereas no change was found in levels. To support our in vivo observation we carried out experiments in vitro using guinea-pig LPS-stimulated adherent peritoneal cells which release large amounts of IL-8 into the supernatants. When rIL-5 was added to LPS-stimulated cells, 65% inhibition of IL-8 release into the supernatants was observed. Pre-incubation of cells with anti-IL-5 Ab prevented the inhibition of IL-8 release into the supernatants induced by rIL-5. Our results demonstrate for the first time that TNF- α and IL-8 are released concomitant with or after IL-5 in the eosinophilic inflammation induced by T. canis . Moreover, in addition to showing that IL-5 is fundamental for the induction of blood eosinophilia, the present results suggest that this cytokine may play a new biological role by acting as modulator of IL-8 secretion.

    Full Text Available Background: Acute eosinophilic pneumonia (AEP is one of the heterogeneous group of disorders termed eosinophilic lung diseases showing an abnormal accumulation of eosinophils in distal airways, air spaces, and the interstitial compartment of the lung. AEP is characterized by acute febrile respiratory failure, a typical radiographic pattern similar to that of acute pulmonary edema, eosinophilia in bronchoalveolar lavage (BAL, a dramatic response to corticosteroid therapy with no relapse when tapering or withdrawing treatment in the absence of infection. It can be idiopathic o secondary to known causes such as drugs, or fungal and parasitic infections. Clinical case: We report a case of a 76-year-old woman who developed symptoms, respiratory signs, and radiological and histological findings compatible with secondary AEP, we assessed as being associated with sertraline assumption (second case in literature. Discussion: The AEP we detected could be related to a secondary hypersensitivity syndrome to drug exposure (DRESS syndrome: Drug Rush with Eosinophilia and Systemic Symptoms characterized by 1 skin rush, 2 increased eosinophilia, and 3 systemic involvement. The presence of all three criteria confirmed our diagnosis.

  19. Therapeutic targeting of eosinophil adhesion and accumulation in allergic conjunctivitis

    Full Text Available Considerable evidence indicates that eosinophils are important effectors of ocular allergy. Increased worldwide prevalence of allergic eye pathologies has stimulated the identification of novel drug targets, including eosinophils and adhesion molecules.Accumulation of eosinophils in the eye is a key event in the onset and maintenance of allergic inflammation and is mediated by different adhesion molecules. Antihistamines with multiple mechanisms of action can be effective during the early and late phases of allergic conjunctivitis by blocking the interaction between β1 integrins and vascular cell adhesion molecule (VCAM-1. Small molecule antagonists that target key elements in the process of eosinophil recruitment have been identified and reinforce the validity of α4β1 integrin as a therapeutic target.Glucocorticoids are among the most effective drugs for ocular allergy, but their use is limited by adverse effects. Novel dissociated glucocorticoids can prevent eosinophil accumulation and induce apoptosis of eosinophils, making them promising candidates for ophthalmic drugs.This article reviews recent understanding of the role of adhesion molecules in eosinophil recruitment in the inflamed conjunctiva along with effective treatments for allergic conjunctivitis.

    Plasminogen activator inhibitor-2 (PAI-2) as a potential eosinophil protein was inferred from our gene microarray study of mouse eosinophilopoiesis. Here, we detect 47 kDa intracellular and approximately 60 kDa secretory forms of PAI-2 in purified human eosinophil extracts. PAI-2 is present at variable concentrations in eosinophil lysates, ranging from 30 to 444 ng/10(6) cells, with a mean of 182 ng/10(6) cells from 10 normal donors, which is the highest per-cell concentration among all leukocyte subtypes evaluated. Enzymatic assay confirmed that eosinophil-derived PAI-2 is biologically active and inhibits activation of its preferred substrate, urokinase. Immunohistochemical and immunogold staining demonstrated PAI-2 localization in eosinophil-specific granules. Immunoreactive PAI-2 was detected in extracellular deposits in and around the eosinophil-enriched granuloma tissue encapsulating the parasitic egg in livers of wild-type mice infected with the helminthic parasite Schistosoma mansoni. Among the possibilities, we consider a role for eosinophil-derived PAI-2 in inflammation and remodeling associated with parasitic infection as well as allergic airways disease, respiratory virus infection, and host responses to tumors and metastasis in vivo.

    Full Text Available Alcohol consumption is common problem in Uganda. Among the types of alcohols consumed include beers, spirits, liqueurs, wines and traditional brew. These alcohols are easily accessible and consumed by many people including the HIV infected patients who are on the d4T/3TC/NVP regimen. The aim of this study was to determine the effect of chronic alcohol intake on the red blood cell count (RBC and the RBC indices in the HIV-infected patients on d4T/3TC/NVP regimen. It was a case control study that used a repeated measures design model where serial measurements of the red blood cell count (RBC and RBC indices were determined at 3 month interval for 9 months. A total of 41 HIV infected patients were recruited and grouped into two arms; the control group had 21 patients and the chronic alcohol group had 20 patients. The RBC and RBC indices of the whole blood were determined using automated hematological Coulter CBC-5 Hematology Analyzer system using standard procedures. The data was sorted into alcohol-use self reporting by WHO AUDIT tool and alcohol-use biomarkers groups. It was analysed using the SAS 2003 version 9.1 statistical package with the repeated measures fixed model. The means were compared using the student t-test. The mean MCV and MCH values in the chronic alcohol use group were higher than in the control group and there was a significant difference between the 2 groups (p<0.05 for both the WHO AUDIT tool group and chronic alcohol use biomarkers group. The mean RBC count, Hct, HGB and MCHC values in both the control and chronic alcohol use groups were within the normal reference ranges for both groups though the trend was lower in alcohol group. Chronic alcohol use affects the RBC and RBC indices in the HIV infected patients on d4T/3TC/NVP treatment regimen. [Int J Basic Clin Pharmacol 2013; 2(5.000: 528-536

    2013-03-01

    Feline gastrointestinal eosinophilic sclerosing fibroplasia was diagnosed in an 8-month-old Scottish fold that had a primary gastrointestinal mass involving the stomach, duodenum and mesenteric lymph nodes. Histopathologically, the most characteristic feature of this mass was granulation tissue with eosinophil infiltration and hyperplasia of sclerosing collagen fiber. Immunohistochemically, large spindle-shaped cells were positive for smooth muscle actin and vimentin. This case emphasizes the importance of feline gastrointestinal eosinophilic sclerosing fibroplasia as a differential diagnosis of gastrointestinal neoplastic lesions such as osteosarcoma and mast cell tumor in cats.

    Eosinophilic cholecystitis (EC) is a rare disease that is characterised by eosinophilic infiltration of the gallbladder. Its pathogenesis is unknown, although many hypotheses have been made. Clinical and laboratory manifestations do not differ from those of other causes of cholecystitis. Diagnosis is histological and usually performed after analysis of the surgical specimen. We report the case of a woman aged 24 years, with symptoms of fever, vomiting and pain in the right upper quadrant. When imaging tests revealed acalculous cholecystitis, an urgent cholecystectomy was performed. Histological examination of the surgical specimen revealed eosinophilic cholecystitis. No cause of the symptoms was found.

    Full Text Available The aim of the present study was to comparatively evaluate hemogram, blood serum components and anatomopathologic alterations in commercial layers experimentally challenged with an attenuated vaccine candidate strain (SG∆cobS∆cbiA and other two pathogenic strains (SGDcobS and SGNalr of Gallinarum (SG. In total, 280 commercial layers were randomly divided into 4 groups (G1, G2, G3 and G4. At five days of age, birds from groups G1 received approximately 107 colony forming units (CFU of SGDcobS; meanwhile birds from group G2 and G3 received the same dose of SGNalr and SG∆cobS∆cbiA, respectively. Birds from G4 were not infected. At 24 hours before (DBI and 24 hours after (1 DAI, and three (3 DAI, five (5 DAI, seven (7 DAI ten (10 DAI, and fifteen (15 DAI days after the infection, 10 birds of each group were humanely killed and blood samples collected to hematological and serum tests. Samples of liver, spleen, thymus, bursa of Fabricius, kidney and heart were also collected for the histological examination. Birds inoculated with SGDcobS and SGNalr showed similar alterations in hemogram, blood serum components and anatomopathologic exams. On the other hand, the exams of birds inoculated with SG∆cobS∆cbiA strain were similar to those of the uninfected birds. However, changes could be noticed in levels of uric acid and cholesterol during the course of the infection of birds from G3. Decrease in levels of light IgG 3 DAI was also observed in birds from this group. Pyknosis in kidney cells was a microscopic alteration found in birds from G3. Further studies must be done to verify if these alterations will not interfere in the performance of the vaccinate birds with SG∆cobS∆cbiA strain.

    El eosinófilo es una célula con funciones protectoras y beneficiosas especificas pero que en algunas circunstancias Interviene como mediador en diferentes procesos fisiopatológicos. Un recuento aumentado en la sangre periférica (mayor de 500 células/mm cúbico siempre debe investigarse porque puede ser el Indicador precoz de una enfermedad o la guía para llegar a un diagnóstico.

    The eosinophil is a cell with specific protective and beneficial functions but In some circumstances It acts as a mediator in different physiopathologic processes. Increased periphery blood counts (more than 500 cells/cubic mm should always be investigated since they may be the earliest indication of a disease or represent an important diagnostic guide.

    In veterinary medicine a complete blood cell count (CBC) cannot always be performed within 24 h as usually recommended, particularly for specimens shipped to a reference laboratory. This raises the question of the stability of the variables, especially in ethylenediamine tetra-acetic acid (EDTA) feline blood specimens, known to be prone to in vitro platelet aggregation. Citrate, theophylline, adenosine and dipyridamole (CTAD) has been reported to limit platelet aggregation in feline blood specimens. The aim of this study was to measure the stability of the haematological variables and the platelet aggregation score in EDTA and EDTA plus CTAD (EDCT) feline blood specimens during 48 h of storage at room temperature. Forty-six feline EDTA and EDCT blood specimens were analysed with a Sysmex XT-2000iV analyser, and the platelet count and score of platelet aggregation were estimated immediately and after 24 and 48 h of storage. A significant increase in mean corpuscular volume, haematocrit, reticulocyte and eosinophil counts, and a significant decrease in mean corpuscular haemoglobin concentration and monocyte count were observed. Haemoglobin, mean corpuscular haemoglobin, and red blood cell, white blood cell, neutrophil and lymphocyte counts remained stable. Changes in reticulocyte indexes with time (low fluorescence ratio, medium fluorescence ratio, high fluorescence ratio and immature reticulocyte fraction) were not significant. Changes were generally more pronounced in EDTA than in EDCT. Platelet aggregation decreased markedly in initially highly aggregated EDTA specimens, and increased slightly in initially non- or mildly-aggregated EDTA or EDCT specimens. Platelet counts increased and decreased, or remained stable, respectively. CTAD can reduce storage-induced changes of the haematological variables in feline samples, thus improving the reliability of a CBC and limiting clinical misinterpretations.

    @@ Severe acute respiratory syndrome (SARS) is an infectious disease that originally emerged in China in November 2002. It subsequently spread worldwide.Investigators involved in an international collaboration have attempted to determine a specific etiology in order to redefine what is currently best described as a syndrome into a specific disease. At present, a novel coronavirus is generally accepted as the single most probable causative agent. In the case of HIV infection, monocytes/macrophages are infected early in the infection process,and the activation of monocytes/macrophages can influence the susceptibility of these cells to infection. 1Therefore, we examined the number of monocytes and the expression of CD14 and HLA-DR in the peripheral blood of patients with SARS to determine whether monocytes were involved in the pathogenesis of SARS.

    Eosinophils are associated with various disorders, such as allergic or hypersensitivity reactions, parasitic diseases, connective tissue diseases, certain neoplastic diseases (Hodgkin's disease, lymphomas, and carcinomas), and various immune deficiency states. Eosinophils can infiltrate any tissue and can cause tissue damage. Heart, has been demonstrated to be the most extensively involved and toxicity of eosinophils is well-established on cardiac tissue. We describe 3 cases with extensive eosinophilic infiltration without endomyocardial fibrosis. All patients died after a short clinical course with rapidly progressive heart failure. Bronchial asthma, hydatid disease and drug reaction were considered as possible etiologies of eosinophilia in case 1 and case 2. Case 3 was considered to fall into the "idiopathic hypereosinophilic syndrome" in which no underlying causes for eosinophilia could be identified.

    Eosinophilic granuloma is a common expression of Langerhans cell histiocytosis and corresponds with typical bone lesions. The radiographic appearance of eosinophilic granuloma in the jaw is variable and not specific. It may resemble periodontitis, radicular cyst, or malignancies. The purpose of this report is to describe the characteristic radiographic features of eosinophilic granuloma of a 39-year-old male. The lesion in the anterior mandible was first diagnosed as radicular cyst because the radiographic findings were ovoid radiolucent lesion with well-defined border. However, careful interpretation revealed a non-corticated border and floating tooth appearance that were the characteristic radiographic features for the differential diagnosis. Early clinical signs of eosinophilic granuloma can occur in the jaw and a bony destructive lesion might be mistaken for periodontitis or an odontogenic cystic lesion; therefore, careful interpretation of radiographs should be emphasized.

    Reports of eosinophilic infiltration of the colon causing obstruction are few. It is even less common to find associated extensive intestinal venulitis, which is similar to and lumped together with so called Mesenteric Inflammatory Veno-Occlusive Disease (MIVOD) or Self-Limited Intestinal Venulitis. Eosinophilic necrotizing lymphadenitis, such as what we report here, has never been reported in association with this disease. A 41-year-old female presented with cramping lower abdominal pain, hematochezia, nausea, and vomiting. Computed tomography revealed the presence of the mass and thickening of the illeocecal wall. Endoscopy confirmed a cecal mass with surface ulceration suggestive of cecal adenocarcinoma. Patient underwent right hemicolectomy with the clinical and radiologic diagnosis of adenocarcinoma. Microscopic examination of the resected bowel showed an ulcerated mass in the cecum composed of markedly edematous tissue showing transmural eosinophilic infiltration and extensive eosinophilic and lymphocytic venulitis with and without thrombosis. This was associated with a necrotizing lymphadenitis.

    Blood samples were collected from 20 Hispaniolan Amazon parrots (Amazona ventralis) and were divided into tubes that contained dipotassium ethylenediaminetetraacetic acid (K2EDTA) and lithium heparin. Complete blood cell counts were determined in each sample within 2 hours of collection. The level of agreement in results was moderate for plasma protein, packed cell volume (PCV), and leukocyte, monocyte, and lymphocyte counts between the anticoagulants. Plasma protein and PCV values were significantly lower in samples with lithium heparin than in those with K2EDTA, whereas lymphocyte numbers were significantly higher in lithium heparin samples than in K2EDTA samples. The level of agreement was good for the other cell types (heterophils, eosinophils, and basophils) when comparing the different anticoagulants. The poor level of agreement between anticoagulants with the increase in thrombocyte clumping in lithium heparin samples indicates that the use of lithium heparin as anticoagulant may affect thrombocyte count. No negative effects on morphology and staining of blood cells were apparent in smears from heparin samples compared with K2EDTA samples. Within the different values compared, the limits of agreement are small enough to be confident that lithium heparin can be used for routine CBC counts in a clinical setting. The use of the same anticoagulant should be recommended to follow trends within the same patient, especially when considering plasma protein concentration, PCV, and lymphocyte count.

    Full Text Available Eosinophilic Esophagitis is infiltration of esophagus mucosa by eosinophil leucocyte. It is rarely observed in children and the symptoms are similar to gastroesophageal reflux. This case, which was applied esophagus balloon dilatation in the pediatric surgery due to dysphagia and diagnosed eosinophilic esophagitis, was presented in order to attract attention to the approach to the child with dysphagia. Total IgE=834 IU/mL and specific IgE (-, Fx5 (- was found negative. In the upper GIS endoscopy, it was observed that esophagus mucosa was pale, its structure was hard and its motility was disordered and a couple milimetric white lesions were observed as well. In the esophagus biopsy materials, it was observed that the eosinophil infiltration in the mucosa was 60%. With the diagnosis of Eosinophilic Esophagitis, the case was started on oral prednisolone 1 mg/kg/day. In the polyclinic control of the case after a week, it was observed that there was a significant decrease in the complaints about dysphagia and in the one-month control the complaints were all gone. In the symptoms similar to dysphagia and reflux, especially if the case is not responding to gastroesophageal reflux treatment, the diagnosis of Eosinophilic Esophagitis should absolutely be considered

    Full Text Available While normal human eosinophils are destroyed in vitro by virulent Entamoeba histolytica, notwhistanding the presence of antibodies and complement, activated eosinophils promptly destroy the parasite although dying also at the end of the process. To study the possible in vivo participation of eosinophils in invasive amebiasis, we compared the induction of experimental amebic abscess of the liver (AAL in gerbils (Meriones unguiculatus previously made eosinophilic through Toxocara canis antigen injection and in normal control gerbils. After intraportal inoculation of 10(5 ameba trophozoites (6 and 24 hr, the ratio of gerbils with AAL, as well as the number and size of the microabscesses was comparable in eosinophilic and control gerbils. However, at 96 hr the number and size of the microabscesses were significanly smaller (p<0.05 in eosinophilic gerbils. On the other hand the actuarial AAL survival curve up to 45 days post-amebic inoculation was signficantly (p<0.05 shifted to the right in controls. These results suggest that antigen-induced eosinophilia may exert a protective effect against AAL in gerbils.

    In the peripheral blood of the roadside hawk, Buteo magnirostris, the following types of granulocytic leucocytes were identified: heterophil, eosinophil and basophil. The heterophils presented acidophilic and spindle shaped granules, the eosinophils possess spherical eosinophilic granules and the basophils showed spherical and basophilic granules. The heterophils and eosinophils presented positive cytochemical reaction to glycogen and basic polyaminoacid, while the eosinophils presented sudanophilic granules, which were also positive for myeloperoxidase. The heterophils, alone, presented positivity for acid phosphatase in some granules and immunoreactivity to TGF-beta1 was observed only in the cytoplasm of the eosinophils. Electron microscopy demonstrated the heterophil granules as predominantly spindle shaped, being strongly electron-dense, while the eosinophils had numerous uniformly electron-dense spherical granules and the basophils presented three different types of granules identified according to their electron-density and the aspect of their matrix.

  9. Cholesterol selectively regulates IL-5 induced mitogen activated protein kinase signaling in human eosinophils.

    Directory of Open Access Journals (Sweden)

    Mandy E Burnham

    Full Text Available Eosinophils function contributes to human allergic and autoimmune diseases, many of which currently lack curative treatment. Development of more effective treatments for eosinophil-related diseases requires expanded understanding of eosinophil signaling and biology. Cell signaling requires integration of extracellular signals with intracellular responses, and is organized in part by cholesterol rich membrane microdomains (CRMMs, commonly referred to as lipid rafts. Formation of these organizational membrane domains is in turn dependent upon the amount of available cholesterol, which can fluctuate widely with a variety of disease states. We tested the hypothesis that manipulating membrane cholesterol content in primary human peripheral blood eosinophils (PBEos would selectively alter signaling pathways that depend upon membrane-anchored signaling proteins localized within CRMMs (e.g., mitogen activated protein kinase [MAPK] pathway, while not affecting pathways that signal through soluble proteins, like the Janus Kinase/Signal Transducer and Activator of Transcription [JAK/STAT] pathway. Cholesterol levels were increased or decreased utilizing cholesterol-chelating methyl-β-cyclodextrin (MβCD, which can either extract membrane cholesterol or add exogenous membrane cholesterol depending on whether MβCD is preloaded with cholesterol. Human PBEos were pretreated with MβCD (cholesterol removal or MβCD+Cholesterol (MβCD+Chol; cholesterol delivery; subsequent IL-5-stimulated signaling and physiological endpoints were assessed. MβCD reduced membrane cholesterol in PBEos, and attenuated an IL-5-stimulated p38 and extracellular-regulated kinase 1/2 phosphorylation (p-p38, p-ERK1/2, and an IL-5-dependent increase in interleukin-1β (IL-1β mRNA levels. In contrast, MβCD+Chol treatment elevated PBEos membrane cholesterol levels and basal p-p38, but did not alter IL-5-stimulated phosphorylation of ERK1/2, STAT5, or STAT3. Furthermore, M

    Eosinophil peroxidase (EPO) and lactoperoxidase (LPO) are important constituents of the innate immune system of mammals. These heme enzymes belong to the peroxidase-cyclooxygenase superfamily and catalyze the oxidation of thiocyanate, bromide and nitrite to hypothiocyanate, hypobromous acid and nitrogen dioxide that are toxic for invading pathogens. In order to gain a better understanding of the observed differences in substrate specificity and oxidation capacity in relation to heme and protein structure, a comprehensive spectro-electrochemical investigation was performed. The reduction potential (E degrees ') of the Fe(III)/Fe(II) couple of EPO and LPO was determined to be -126mV and -176mV, respectively (25 degrees C, pH 7.0). Variable temperature experiments show that EPO and LPO feature different reduction thermodynamics. In particular, reduction of ferric EPO is enthalpically and entropically disfavored, whereas in LPO the entropic term, which selectively stabilizes the oxidized form, prevails on the enthalpic term that favors reduction of Fe(III). The data are discussed with respect to the architecture of the heme cavity and the substrate channel. Comparison with published data for myeloperoxidase demonstrates the effect of heme to protein linkages and heme distortion on the redox chemistry of mammalian peroxidases and in consequence on the enzymatic properties of these physiologically important oxidoreductases.

    Full Text Available We studied the interaction between deoxynivalenol (DON-feeding and a subsequent pre- and post-hepatic immune stimulus with the hypothesis that the liver differently mediates the acute phase reaction (APR in pigs. Barrows (n = 44 were divided into a DON-(4.59 mg DON/kg feed and a control-diet group, surgically equipped with permanent catheters pre- (V. portae hepatis and post-hepatic (V. jugularis interna and infused either with 0.9% NaCl or LPS (7.5 µg/kg BW. Thus, combination of diet (CON vs. DON and infusion (CON vs. LPS, jugular vs. portal created six groups: CON_CONjug.-CONpor., CON_CONjug.-LPSpor., CON_LPSjug.-CONpor., DON_CONjug.-CONpor., DON_CONjug.-LPSpor., DON_LPSjug.-CONpor.. Blood samples were taken at −30, 15, 30, 45, 60, 75, 90, 120, 150, 180 min relative to infusion and analyzed for leukocytes and TNF-alpha. Concurrently, clinical signs were scored and body temperature measured during the same period. LPS as such induced a dramatic rise in TNF-alpha (p < 0.001, hyperthermia (p < 0.01, and severe leukopenia (p < 0.001. In CON-fed pigs, an earlier return to physiological base levels was observed for the clinical complex, starting at 120 min post infusionem (p < 0.05 and persisting until 180 min. DON_LPSjug.-CONpor. resulted in a lower temperature rise (p = 0.08 compared to CON_LPSjug.-CONpor.. In conclusion, APR resulting from a post-hepatic immune stimulus was altered by chronic DON-feeding.

  12. Concentrations of procalcitonin and C-reactive protein, white blood cell count, and the immature-to-total neutrophil ratio in the blood of neonates with nosocomial infections: Gram-negative bacilli vs coagulase-negative staphylococci

    Abstract This study was undertaken to determine whether concentrations of procalcitonin in the blood of neonates with nosocomial infections depend on the type of pathogen. Qualification for the study group was based on the clinical signs of infection. We found that infections with Gram-positive (chiefly coagulase-negative staphylococci) and Gram-negative bacteria are accompanied by elevated concentrations of procalcitonin. In the case of Gram-positive bacteria, other laboratory sig...

  13. Infection of IL5 transgenic mice with Mesocestoides corti induces very high levels of IL5 but depressed production of eosinophils.

    Transgenic mice expressing interleukin 5 (IL5) have been demonstrated to show a lifelong high level eosinophilia. These mice were produced using a construct in which the dominant control region (DCR) of the human CD2 gene was ligated to a 10-kb fragment containing the mouse IL5 gene. The construct allows the expression of the IL5 gene under the control of its own promoter, but the DCR ensures constitutive expression by all T cells. Infection of these transgenic mice with Mesocestoides corti, which is itself a potent inducer of eosinophilia, increases serum IL5 to very high levels. This demonstrates that the transgenes retain inducibility, which is a feature of the endogenous gene. However, despite the high levels of IL5, the numbers of eosinophils in the blood, marrow, and spleen decrease during the period 1-4 weeks after infection. Furthermore, there is a decrease in eosinophil precursors, as assessed by the capacity of bone marrow to produce eosinophils in culture. After this decrease eosinophils return to their previous high levels, although the levels of IL5 remain high. These results suggest that a control mechanism is operating to limit the numbers of eosinophils produced. This control appears to act at the level of the precursor production and may not be directly related to the high levels of IL5.

    Eosinophil granulocytes have been implicated in anticancer immunity but recent data indicate that eosinophils can also promote cancer. Herein, we studied eosinophils in skin lesions from 43 patients with mycosis fungoides (MF). The presence of eosinophils correlated with disease stage: 78% of patients with advanced disease displayed eosinophil infiltration, whereas this was only seen in 11% of patients with patches (pIL5). STAT3 siRNA profoundly inhibited IL5 but not HMGB1 expression. In conclusion, these data suggest that malignant T-cells orchestrate accumulation and activation of eosinophils supporting the notion of STAT3 being a putative target for therapy.

    A 22-year-old woman was admitted with symptoms of dyspnea and fever with pulmonary infiltrates noted on her chest X-ray study. She developed these symptoms in the workplace; her job included the removal of body hair using a diode-laser with 1,1,1,2-tetrafluoroethane (HFC134a, an alternative to chlorofluorocarbon) as a coolant. A chest X-ray examination revealed ground-glass opacities in the lower lung fields, and a chest computed tomographic study showed diffuse centrilobular opacities. An examination of the bronchoalveolar lavage fluid revealed increased lymphocytes with a slight increase in the number of eosinophils. An examination of the transbronchial biopsy specimens revealed eosinophil infiltration. A peripheral blood eosinophilia was also seen. The patient's symptoms, chest X-ray findings, and arterial blood gas analysis all returned to normal within a week. A challenge test of 1,1,1,2-tetrafluoroethane (HFC134a) inhalation was performed, which resulted in an elevation of body temperature, the development of a cough, and laboratory data indicating increased inflammation. We then determined the patient's diagnosis to be extrinsic allergic alveolitis with eosinophil infiltration, caused by HFC134a.

    To describe the radiological features of pulmonary tuberculosis (TB) in patients infected with human immunodeficiency virus (HIV) and its correlation with the blood CD4 cell count. We present 44 HIV+patients, 24 with CD4 cell counts of less than 200 cells/mm''3 (group A) and 20 in whom the CD4 counts surpassed this level (group B). We also assessed the chest x-ray images to determine whether or not there was any correlation with the blood CD4 cell counts. Fisher's exact test was used for the statistical study of the differences in the radiological findings in the two groups. The incidence of atypical features was significantly greater in the patients with CD4 cell counts of less than 200 cells/mm''3 (group A) than in those with CD4 counts of over 200 cells/mm''3 (group B). Among HIV+patients, those with a more intact immune status were more likely to present lung x-ray images typical of post-primary TB, with cavitary lesions in upper lobes. The group of patients in whom the immune deficiency was more marked showed a greater incidence of atypical pulmonary findings, more characteristics of primary TB. (Author)

    Full Text Available In cats, the most common eosinophilic dermatoses are feline miliary dermatitis and eosinophilic granuloma complex. The most commonly identified underlying cause is a hypersensitivity reaction. Few cases of familial forms of eosinophilic dermatoses are reported in the literature. Two young adult cats from the same litter presented 2 years apart with a severe and chronic fluid or tissue infiltration of the distal part of several limbs. Lesions started on the forelegs and developed on the other limbs. Cytological and histopathological examinations showed lesions consistent with an atypical form of feline eosinophilic dermatosis associated with secondary bacterial infection. In both cats, antibiotics combined with immunosuppressive treatment partially improved the lesions, which continued to progress on a waxing and waning course, even in the absence of treatment. Allergy work-up did not permit the identification of an underlying allergic triggering factor. The severity of the lesions, the unusual presentation and the unsatisfactory response to immunosuppressive therapy in two feline littermates suggested a genetic form of eosinophilic dermatosis.

    Eosinophilic esophagitis has rapidly become a recognized entity causing dysphagia in young adults. This review summarizes the current knowledge of eosinophilic esophagitis including the epidemiology, clinical presentation, diagnostic criteria, pathophysiology, treatment,and prognosis. An extensive search of PubMed/Medline (1966-December 2005) for available English literature in humans for eosinophilic esophagitis was completed. Appropriate articles listed in the bibliographies were also attained. The estimated incidence is 43/105 in children and 2.5/105 in adults. Clinically, patients have a long history of intermittent solid food dysphagia or food impaction. Some have a history of atopy. Subtle endoscopic features may be easily overlooked, including a "feline"or corrugated esophagus with fine rings, a diffusely narrowed esophagus that may have proximal strictures, the presence of linear furrows, adherent white plaques, or a friable (crepe paper) mucosa, prone to tearing with minimai contact. Although no pathologic consensus has been established, a histologic diagnosis is critical. The accepted criteria are a dense eosinophilic infiltrate (>20/high power field) within the superficial esophageal mucosa. In contrast, the esophagitis associated with acid reflux disease can also possess eosinophils but they are fewer in number. Once the diagnosis is established, treatment options may include specific food avoidance, topical corticosteroids, systemic corticosteroids, leukotriene inhibitors,or biologic treatment. The long-term prognosis of EE is uncertain; however available data suggests a benign,albeit inconvenient, course. With increasing recognition,this entity is taking its place as an established cause of solid food dysphagia.

    Canine pulmonary eosinophilic granulomatosis is a rare inflammatory pulmonary disease characterized by formation of eosinophilic granulomas that tend to obliterate the normal pulmonary architecture. The purpose of this retrospective study was to describe the CT characteristics of confirmed idiopathic pulmonary eosinophilic granulomatosis in a group of dogs. Five dogs met inclusion criteria. All patients were young adult dogs of variable breeds. No dog had concurrent occult heartworm disease. Computed tomographic characteristics most commonly included pulmonary masses and nodules of variable size, and lesions were most commonly located in the caudal lung lobes. Four dogs had large pulmonary masses with or without additional nodules and one dog had nodular lesions disseminated throughout the entire lung parenchyma. All large eosinophilic granulomas were smoothly margined, heterogeneous pulmonary masses displaying heterogeneous contrast enhancement. A honeycomb-like enhancement pattern was observed in all but one mass and consisted of multiple hyperattenuating rims delineating central hypoattenuating areas, suggestive of bronchiectatic lung with peripheral enhancing airway walls and fluid-filled, necrotic bronchial lumen. One dog had evidence of tracheobronchial lymphadenopathy. Findings indicated that canine eosinophilic pulmonary granulomatosis should be included as a differential diagnosis for dogs with CT characteristics of multiple pulmonary masses and/or nodules in caudal lung lobes, and a honeycomb-like enhancement pattern in masses after intravenous administration of iodinated contrast medium.

    Eosinophilic esophagitis(Eo E) is a clinico-pathological entity with esophageal symptoms and dense esophageal eosinophilic infiltration throughout the esophagus that may persist despite treatment with proton pump inhibitors. This eosinophilic infiltration is usually absent in the stomach, small intestine and colon, although there are a number of reports of patients with a multiorgan involvement. EoE is associated with abnormalities involving TH2-dependent immunity, with multiple environmental factors strongly contributing to disease expression. The layer of the esophagus affected by the eosinophilic infiltration causes the specific symptoms. Esophageal involvement results mostly in dysphagia for solids that can be severe enough to cause recurrent esophageal obstruction with typical endoscopic features suggesting esophageal remodeling and pathological changes of eosinophilic infiltration of the mucosa, sub-epithelial fibrosis and muscle hypertrophy. This disease is frequently associated with other allergic conditions such as allergic asthma, allergic dermatitis and eosinophilia. The treatment of patients with Eo E depends on the severity of the symptoms and of the inflammatory process as well as to their response to a gradual step-up treatment. The first line of treatment consists of steroid containing local inhalers. If unresponsive they are then treated with oral steroids. Intravenous interleukin blockers seem to have a consistent positive therapeutic effect.

    It has been suggested that Fas ligand–Fas receptor interactions are involved in the regulation of eosinophil apoptosis and that dysfunctions in this system could contribute to the accumulation of these cells in allergic and asthmatic diseases. Here, we demonstrate that nitric oxide (NO) specifically prevents Fas receptor–mediated apoptosis in freshly isolated human eosinophils. In contrast, rapid acceleration of eosinophil apoptosis by activation of the Fas receptor occurs in the presence of eosinophil hematopoietins. Analysis of the intracellular mechanisms revealed that NO disrupts Fas receptor–mediated signaling events at the level of, or proximal to, Jun kinase (JNK), but distal to sphingomyelinase (SMase) activation and ceramide generation. In addition, activation of SMase occurs downstream of an interleukin 1 converting enzyme–like (ICE-like) protease(s) that is not blocked by NO. However, NO prevents activation of a protease that targets lamin B1. These findings suggest a role for an additional NO-sensitive apoptotic signaling pathway that amplifies the proteolytic cascade initialized by activation of the Fas receptor. Therefore, NO concentrations within allergic inflammatory sites may be important in determining whether an eosinophil survives or undergoes apoptosis upon Fas ligand stimulation. PMID:9449721

    Background. Eosinophilic esophagitis is an inflammatory condition where there is a dense infiltration of eosinophils typically exceeding fifteen cells per high power field. Familial Mediterranean fever is an autosomal recessive disorder characterized by brief, acute, and self-limited episodes of fever and polyserositis that recur at irregular intervals. Case Presentation. A three-year-and-nine-month-old Iranian girl was admitted to our center. The patient's parents complained of a history of abdominal pain, poor appetite, and poor weight gain from 1.5 years ago and episodes of food impaction after starting solid foods. Eosinophilic esophagitis was diagnosed based on histology. Because of continuing abdominal pain after treatment of eosinophilic esophagitis, the episodic nature of disease, and the presence of fever with pain, screening for familial Mediterranean fever mutation was performed and the patient was found to be heterozygote for Mediterranean fever. Conclusion. We have reported a case of eosinophilic esophagitis coexisting with familial Mediterranean fever which has not been described previously. PMID:28255474

    Full Text Available CONTEXT: Eosinophilic esophagitis is an entity characterized by an esophageal inflammatory infiltrate of eosinophils, manifested by dysphagia, intermittent food impactions and symptoms similar to gastroesophageal reflux disease (GERD, that predominantly affects young adults. There may be association of eosinophilic esophagitis with GERD, and motor abnormalities have been described. OBJECTIVE: The main objectives of this study are to describe the findings at esophageal manometry and pH monitoring in patients with eosinophilic esophagitis. METHODS: Cross-sectional study of 20 patients with a diagnosis of eosinophilic esophagitis, submitted to esophageal manometry and 24h pH monitoring. Were analysed the manometric changes and the presence of abnormal reflux on pH monitoring. RESULTS: Twenty patients (15 men, 5 women had a mean age of 29 years. Motility disorders were found in 25% (5/20 patients with ineffective esophageal motility being the most common finding. pH monitoring revealed abnormal reflux on 25%, without any relationship with manometric findings. CONCLUSIONS: Manometric abnormalities were observed in 25% of patients and abnormal reflux on pH monitoring also in 25%. This study showed no relationship between abnormal reflux and the presence of manometric changes.

  5. Biochemical characterization of reactive nitrogen species by eosinophil peroxidase in tyrosine nitration

    Full Text Available It is well known that eosinophils are involved in tyrosine nitration. In this study, we evaluated tyrosine nitration by rat eosinophils isolated from peritoneal fl uid and constituent eosinophils in the stomach. Rat peritoneal eosinophils activated with 1 μM phorbol myristate acetate (PMA and 50 μM NO2 ン showed immunostaining for nitrotyrosine only in smaller cells, despite the fact that eosinophils are capable of producing superoxide (O2·ン. Free tyrosine nitrating capacity after incubation with PMA and NO2 ン was 4-fold higher in eosinophils than in neutrophils. Catalase and ク- and コ -tocopherol inhibited free tyrosine nitration by reactive nitrogen species from eosinophils but not that by peroxynitrite. Superoxide dismutase augmented free tyrosine nitration by activated eosinophils and peroxynitrite. The concentration of nitric oxide released from eosinophils was relatively low (0.32 μM/106 cells/h and did not contribute to the formation of nitrotyrosine. On the other hand, most constituent eosinophils constituent in the rat stomach stimulated by PMA and NO2 ン showed tyrosine nitration capacity. These results suggest that intact cells other than apoptotic-like eosinophils eluted in the intraperitoneal cavity could not generate reactive species responsible for nitration by a peroxidase-dependent mechanism. In contrast, normal eosinophils in the stomach were capable of nitration, suggesting that the characteristics of eosinophils in gastric mucosa are diff erent from those eluted in the peritoneal cavity.

    Full Text Available Eosinophilic Gastroenteritis is a rare disease characterized by infiltration of the gastrointestinal tract by an increased number of eosinophils as compared to the normal. The anatomic location and intensity of the infiltrate decides the varied clinical symptomatology with which these patients present. The present report deals with four cases, all presenting with clinical signs of intestinal obstruction A laparotomy performed revealed a stricture in the first case, superficial ulcers and adhesions in the second case, an ileocaecal mass in the third case and volvulus formation in the fourth case. Eosinophilic gastroenteritis was confirmed on histopathology in all the four cases. All the four patients experienced relief of symptoms after resection. It is essential to diagnose the disease to differentiate it from other conditions presenting as intestinal obstruction. The cases are presented because of the rarity of occurrence and presentation. Relevant literature has been reviewed.

    Eosinophilic granuloma of bone or Langerhans cell histiocytosis is mostly unifocal. It appears on plain X Ray as a solitary destructive lesion of long bones or flat bones. Computerized tomography (CT) is useful to define the extension to the cortical bone and also to precisely localize the lesion when the anatomy is complex (hip, spine, base of the skull). Magnetic resonance (MR) is very useful in case of more aggressive lesions when there is extension to soft tissues. Differential diagnosis includes circumscribed osteitis and tumors in the case of extensive destruction. The natural course of solitary lesions is favorable, spontaneously or with therapy. The prognosis is more serious in the case of multiple lesions. (authors).

    Eosinophilic enteritis (EE) in cats is poorly characterized. The aim of the current study was to retrospectively evaluate the clinical and ultrasonographic findings in cats with histologic evidence of eosinophilic inflammation on gastrointestinal biopsy. Twenty-five cats with tissue eosinophilia on surgical (10) or endoscopic (15) biopsy of the gastrointestinal tract, having an abdominal ultrasound performed within 48 h of biopsy acquisition, were enrolled. History, clinical presentation, clinical pathology and abdominal ultrasound findings were reviewed. Intestinal biopsies were evaluated by a single pathologist and separated into two groups based on the degree of eosinophilic infiltrate: mild (eosinophils/high-power field [HPF], 11/25 cats), or moderate/marked (>10 eosinophils/HPF, 14/25 cats). The former were considered primary lymphoplasmacytic or lymphocytic inflammatory bowel disease (LPE) with subtle eosinophilic infiltrates, and the latter to have EE. Signalment, history and clinical signs were similar in all cats. Only cats with EE (6/14) had palpably thickened intestines. The only distinguishing clinicopathological feature of cats with EE was the presence of peripheral eosinophilia (6/14). On ultrasound, when compared with cats with LPE, cats with EE had a greater mean jejunal wall thickness (3.34 mm ± 0.72 mm vs 4.07 mm ± 0.58 mm, respectively) and an increased incidence of thickening of the muscularis layer (1/11 and 11/14, respectively). In conclusion, ultrasonographic evidence of a prominent intestinal muscularis layer, palpably thickened intestines and peripheral eosinophilia can serve as biomarkers for the presence of EE in cats with chronic intestinal signs.

    Eosinophilic gastroenteritis is an uncommon disease with variable clinical features characterized by eosinophilic infiltration. Clinical manifestations range from non-specific gastrointestinal complaints such as nausea, vomiting, crampy abdominal pain, and diarrhea to specific findings such as malabsorption, protein loosing enteropathy, luminal obstruction, eosinophilic ascites and effusion. We report here on a case of eosinophilic gastroenteritis causing enterobiliary fistula which is an extremely unusual complication

    Eosinophils are multifunctional leukocytes involved in allergic reactions as well as adipose tissue regulation. IL-5 is required for eosinophil survival; however, the in vivo mechanisms of eosinophil regulation are not fully understood. A tg mouse model with il5 promoter-driven EGFP expression was established for detecting the IL-5-producing cells in vivo. Il5-egfp tg mice expressed high levels of EGFP in gonadal adipose tissue (GAT) cells. EGFP(+) cells in GAT were mainly group 2 innate lymphoid cells (ILCs). IL-33 preferentially expanded EGFP(+) cells and eosinophils in GAT in vivo. EGFP(+) ILCs were found to upregulate prg2 mRNA expression in GAT eosinophils. These results demonstrate that ILCs activate eosinophils in GAT. The blockage of IL-33Rα, on the other hand, did not impair EGFP(+) ILC numbers but did impair eosinophil numbers in vivo. GAT eosinophils expressed IL-33Rα and IL-33 expanded eosinophil numbers in CD90(+) cell-depleted mice. IL-33 was further observed to induce the expression of retnla and epx mRNA in eosinophils. These findings demonstrate that IL-33 directly activates eosinophils in GAT, and together with our other findings described above, our findings show that IL-33 has dual pathways via which it activates eosinophils in vivo: a direct activation pathway and a group 2 ILC-mediated pathway.

    Objective:To observe the clinical manifestations of allergic rhinitis mice and the expression changes of the eosinophilsCCR3 and the granule protein mRNA in the bone marrow, peripheral blood and nasal lavage fluid.Methods:Twenty-fourBALB/c mice were randomly divided into the control group,PBS therapy group, siRNA therapy group and theCCR3 siRNA therapy group (n=6).Allergic rhinitis model were sensitized and stimulated by ovalbunfin, andCCR3 siRNA therapy group were administered withCCR3 transnasally before stimulated.The levels of the eosinophilsCCR3,MBP,ECP andEPO in bone marrow, peripheral blood and nasal lavage fluid were detected byRT-PCR.Results:Compared to the control group andCCR3 siRNA therapy group, the nasal mucosa of thePBS therapy group and siRNA therapy group developed epithalaxy, goblet cells hyperplasia, squamous epithelium metaplasia, epithelium necrosis, lamina propria and submucosa gland hyperplasia, vasodilatation, tissue edema, and the characterized eosinophil infiltration.RT-PCR indicated that theCCR3 mRNA,MBP ,ECP andEPO expression in bone marrow, peripheral blood and nasal lavage fluid of theCCR3 siRNA therapy group was lower than thePBS therapy group andsiRNA therapy group(P<0.05).Conclusions:TheRNA interference therapy toCCR3 by local administration pernasal can suppress the process of the development, migration and invasion of the allergic rhinitis eosinophil, thus can reduce the effect of eosinophils and then reduce the inflammation effect of the allergic rhinitis.It may be a new treatment for respiratory tract allergic inflammation.

    Full Text Available Presentamos un caso de la denominada foliculitis pustulosa eosinofílica o enfermedad de Ofuji, sin eosinofilia periférica ni inmunosupresión asociada. El cuadro respondió inicialmente bien a la dapsona, pero debido a un aumento de enzimas hepáticas y bilirrubina se rotó a terapia tópica con clobetasol y pimecrolimus, con buena respuesta. Efectuamos una revisión del cuadro enfatizando que el mismo constituye una inflamación del epitelio infundibular y no folicular constituyendo un patrón de respuesta a múltiples causas, algunas o la mayoría no bien conocidas.A case of the so called eosinophilic pustular folliculitis or Ofuji´s disease, without blood eosinophilia nor immunosuppression is reported. The patient responded at first well to Dapsone, but an increase of the hepatic enzymes and bilirubin was detected and only topical therapy with clobetazol and pimecrolimus was carried out with a good response. A revision of the disease with emphasis in the concept of infundibulitis rather than folliculitis was made. The eosinophilic pustular folliculitis is a pattern of response to multifactorial, mostly unknown, causes and not a single disease.

    concentration. Temperature and time also influenced the MCV, which showed a decrease in time 12 under temperature of 2°C to 8°C and an increase in time 24 and 48 at room temperature. Storage temperature influenced leukocytes and erythrocytes counts, which showed lower values at room temperature. Hemoglobin, PCV, platelet and PCT did not change significantly. The changes observed did not compromise the results obtained by automatic cell counter, showing that blood samples stored for two days remained in good condition for processing, especially when stored under refrigeration.

    Objective To analyze the hematopoietic cell counts in 4711 cord blood unites and explore the relationship between the cell counts and the therapeutic effect of umbilical cord blood transplantation (UCBT). Methods The distribution of total nucleated cells (TNC) and the absolute CD34 + cells counts were analyzed in 4711 cord blood unites. Meanwhile, the differences among hematopoietic cells input, HLA disparity, gender, age, weight, the type of the disease as well as the survival rates were investigated. Results The median counts of TNC and CD34+ cells were 1. 14 × 109 and 4. 06 × 10, respectively, 93.2% of frozen cord blood was suitable for the transplantation in the patients with weight less than 50kg; the engraft rate was 84. 3% (75/89). Neutrophil cells reconstitution at 0. 5 × 109/L, platelet reconstitution at 20 × 109/L and 50 × 109/L occurred at the 17th, 34th and 46th days of UCBT, respectively. Among 75 engrafted cases, 47 patients got complete remission, 26 patients died and 2 patients relapsed. The incidences of acute graft-versus-host disease (GVHD) with grade Ⅰ -Ⅱ, Ⅲ-Ⅳ and chronic GVHD were 54. 7%, 20. 0% and 9. 3%, respectively. The risk factors of engraftment included age, the counts of TNC and CD34 + cells, the overall survival rate was related to the factors including age, weight and the counts of TNC and CD34 +cells. Conclusions Umbilical cord blood could be considered as the source of hematopoietic stem cells and used for the transplantation of the childhood and adult patients with leukemia when there is no acceptably matched bone marrow donor. The cell counts of TNC and CD34 + cells are useful reference index for the selection of cord blood in UCBT.%目的 分析4711份库存脐血造血细胞含量及探讨脐血造血细胞含量与白血病脐血移植疗效的关系.方法 分析4711例库存脐血总有核细胞数(NC)和CD34+细胞数分布情况,探讨不同的造血细胞输入量、供受者HLA不相合数、受者性别、
