The primary goal of this study was to determine the function of eosinophil cationic protein in iron status in patients infected with Enterobius vermicularis. For this, a total of 583 suspected patients and thirty healthy people of the same age who have visited the AL-Zahra maternity and pediatrics laboratory, AL-Hakeem hospital, AL-Sajad hospital AL-Fruit al-Awsat hospital, and AL-Munadira hospital in AL-Najaf province from July 2020 to June 2021 were screened. The presence of E. vermicularis eggs was estimated by using the saline wet mount technique from faeces samples of all respondents. Blood samples were collected from the 60 positive and 30 healthy control group and centrifuged at 3000 rpm for 5 minutes to separate serum, which was then collected in sterile tubes. Each serum sample was divided into three parts and stored in the deep freezer at -20°C until the serological test was performed. The level of ECP, iron and ferritin in enterobiasis patients was estimated from the isolated blood serum. According to the Manufacturer Company instructions, the concentration of two biomarkers (ECP, Ferritin) in serum samples was determined using the ELISA technique (Human reader, Germany). While the concentration of iron was evaluated using a colourimetric method. In comparison to the control group, the concentration of ECP was reported significantly higher (P<0.05) in the E. vermiculris infected patients while the concentration of serum iron and ferritin was significantly decreased. The results of the current study can be concluded that E. vermicularis infection changes the serum ECP, iron, and ferritin concentration.

The Mean

To study the value of eosinophil cationic protein [ECP] as a serological marker of disease activity in childhood bronchial asthma, ECP levels were measured in 20 healthy control children and 25 asthmatic children, during and 2 weeks after acute exacerbation. The mean serum ECP level of all asthmatic patients, during and after exacerbation, was significantly higher than the control group and was significantly higher during attacks than 2 weeks after their termination. ECP levels were highest in severe attacks, but did not differ between mild and moderate attacks. ECP levels in asthmatic patients 2 weeks after mild and moderate attacks were comparable to normal; after severe attacks levels remained higher than normal. Measurement of serum ECP will be helpful in determining asthma activity and deciding the use of anti-asthma drugs

Abstract Allergic asthma (AA) is a complex disorder with heterogeneous features of airway hyperresponsiveness, inflammation, and remodeling. The increase of airway smooth muscle (ASM) mass is a fundamental component of bronchial remodeling in AA, yet the pathophysiological mechanisms and clinical outcomes associated with ASM modulation are still elusive. The objective of this study is to compare the expression level of β-dystroglycan (β-DG) in ASM in AA subjects and a healthy control group and to investigate the relationship between eosinophils and β-DG in ASM in patients with AA. Thirteen AA patients and seven control subjects were analyzed for the ASM area and eosinophil cells. Bronchial biopsies were stained by β-DG and eosinophil cationic protein (ECP) using immunohistochemistry. The proportion of ASM with β-DG staining was greater in those with AA than in the healthy control group (mean (95% CI) (28.3% (23.8–32.7%) vs. 16.4% (14.1–18.5%), P < 0.0001). The number of ECP positive cells was higher in patients with AA than in the control group (4056 (3819–4296) vs. 466 (395–537) cells/mm2P < 0.0001). In AA, the number of ECP positive cells was significantly correlated to the β-DG expression in ASM (r = 0.77, P = 0.002). There is an increased β-DG expression in ASM and a higher number of ECP positive cells in the bronchial biopsy of those with AA than those in the control group. The increased expression of β-DG in ASM in AA subjects correlates with the number of eosinophils, suggesting a role for this cell in airway remodeling in AA.

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

Background: Essential hypertension is a major public health associated with increase pressure on the vascular walls and red blood cells (RBCs). In the present work, osmotic fragility (OF) of RBCs was reexamined in the means of its correlation with two risk factor; iron status and lipid profile. Experimental: OF, iron status parameters, and lipid profile components were measured in 60 patients and compared with the results of 30 controls. Results: The results showed a significant increase in all iron indices of hypertensive patients in comparing with healthy control group except TIBC, UIBC, and transferrin concentrations, which decrease in these patients in comparing with control group. Serum TGs, total cholesterol, VLDLc, and LDLc were increased while there is no significant in serum HDLc in patients to comparing with control group. There is no significant change in OF between patients and controls where p=0.173. The iron status parameters and lipid profile components were dependent on sex and smoking state. Hemoglobin and PCV were correlated significantly with total cholesterol and LDLc. Transferrin saturation showed a positive correlation with cholesterol, LDLc, and TGs, but negatively correlated with HDLc. No significant correlation between all the measured parameters and OF in HT patients. There is a significant correlation between serum ferritin and systolic BP and between Hb and systolic BP. Conclusion: No significant effect on the OF in HT patients. HT patients have elevated level of iron parameters in comparing with controls. OD has no correlation with iron status parameters or with lipid profile components.

AbstractBullous pemphigoid (BP), the most frequent blistering dermatosis in the elderly, is associated with increased mortality. The severity of BP can be assessed by detecting the anti-BP180 immunoglobulin G (IgG) concentration, but the lab test is not available in many community clinics. BP patients are usually in a hypercoagulable state with increased levels of D-dimer and fibrin degradation products (FDPs). We aimed to evaluate the use of D-dimer and FDPs in assessing BP severity. We compared the levels of plasma D-dimer, plasma FDPs, eosinophil counts, eosinophil cationic protein, and serum anti-BP180 IgG concentration between 48 typical BP patients and 33 Herpes zoster (HZ) patients (control group). Correlational analyses were conducted to determine the relationships between the lab values and common BP severity markers. The plasma D-dimer and FDP levels were higher in BP patients than in HZ controls (D-dimer: 3297 ± 2517 µg/L vs. 569.70 ± 412.40 µg/L; FDP: 9.74 ± 5.88 mg/L vs. 2.02 ± 1.69 mg/L, respectively, P < 0.0001). Significant positive correlations were found between D-dimer/FDP levels and BP severity markers (i.e. anti-BP180 IgG concentration [D-dimer: r = 0.3928, P = 0.0058; FDP: r = 0.4379, P = 0.0019] and eosinophil counts [D-dimer: r = 0.3625, P = 0.0013; FDP: r = 0.2880, P = 0.0472]) in BP patients. We also found an association between FDP and urticaria/erythema lesions (r = 0.3016, P = 0.0372), but no other BPDAI components. In 19 BP patients with complete remission after systemic glucocorticoid treatment, D-dimer and FDP levels decreased post-therapy (D-dimer: 5559 ± 7492 µg/L vs. 1738 ± 1478 µg/L; P < 0.0001; FDP: 11.20 ± 5.88 mg/L vs. 5.13 ± 3.44 mg/L; P = 0.0003), whereas they did not in BP patients with treatment resistant. Plasma D-dimer and FDP are convenient markers to evaluate BP severity assistant on BPDAI and eosinophil counts. FDP is also helpful for inflammatory lesions in BP patients.

Abstract Background. This study aimed to assess the diagnostic performance of lateral flow immunochromatographic assays (LFA) of four different manufacturers to identify SARS-CoV-2 antibodies (IgM, IgG or total), comparing them with the nucleic acid amplification test (NAAT) or clinical defined (definite or probable SARS-CoV-2 infection respectively). Methods. 119 serum samples were randomly selected by convenience and distributed in the groups: (1) Group with SARS-CoV-2 infection [n=82; RT-qPCR positive (definite, n=70), and probable (n=12)]; (2) other diseases [n= 27; other viruses identified (n=8), SARS of other etiologies (n=19)]; (3) healthy control group (n=10). LFA essays of four manufacturers were compared: MedTest Coronavírus (COVID-19) IgG/IgM (MedLevensohn, Brazil); COVID-19 IgG/IgM ECO Test (Ecodiagnóstica, Brazil); Camtech COVID-19 IgM/IgG Rapid Test Kit (Camtech Diagnostics Pte Ltd, Singapore); and one Step COVID-19 Test for total antibodies (Guangzhou Wondfo Biotech Co, China).Results. The four tests studied showed high diagnostic performance characteristics for the diagnoses of definite or probable SARS-CoV-2 infection. The best measures were for the Wondfo test: sensitivity (86.59%; 95%CI, 77.26-93.11%); specificity (100%; 90.51-100%); DOR (257; 60-1008); LR+ (33.43; 4.82-231.85); LR− (0.13; 0.08 - 0.23); accuracy (90.76%; 84.06- 95.29%); Matthews Correlation coefficient (MCC) 0.82. Although considering only the probable SARS-CoV-2 infection (PCR-) cases, all the kits studied showed limited values.Conclusion. Our data demonstrate the excellent performance of LFA for the diagnoses of definite or probable SARS-CoV-2 infection. There was substantial heterogeneity in sensitivities of IgM and IgG antibodies among the manufacturers. LFA tests cannot replace molecular diagnostics, but should be used as additional screening tool.

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

Serum Glutamate

One neurotransmitter, glutamate, has been implicated in the autoimmune demyelination seen in multiple sclerosis (MS). Glutamate is present in many tissues in the body, so consideration should be given to whether the serum level of glutamate is likely well correlated with the activity of the disease. This research aimed to compare the serum glutamate levels from patients diagnosed with MS with those from an age-matched control population. A review of this data could shed light upon whether the serum testing of glutamate using Enzyme-Linked Immunosorbent Assay (ELISA) is a reliable indicator of MS activity. Serum samples were obtained from 55 patients with different patterns of MS and from 25 healthy adults as a control group. The ELISA technique was used to determine the glutamate levels in the serum samples. The mean serum glutamate level for patients with MS was1.318±0.543 nmol/ml and that of the controls was0.873±0.341 nmol/ml. The serum glutamate levels showed an area under the curve via the receiver operating characteristics (ROC) of 0.738, which was significant (pvalue = 0.001). The present study is the first to establish a strong connection between the serum glutamate levels and MS patients, where there was statistically significant elevation of serum glutamate in MS patients; hence this elevation might be used as a monitor to help in the diagnosis of MS patients.
