Abstract Background Rhinitis is a common problem within the population. Many subjects with rhinitis also have atopic multimorbidity, such as asthma and eczema. The purpose of this investigation was to compare subjects with only rhinitis to those that have rhinitis, asthma and/or eczema in relation to immunoglobulin E (IgE) sensitization, inflammatory markers, family history, lung function and body mass index (BMI). Methods A total of 216 adult subjects with rhinitis from the European Community Respiratory Health Survey II were investigated with multiplex component allergen analysis (103 allergen components), total IgE, C-reactive protein, eosinophilic cationic protein, fractional exhaled nitric oxide and spirometry. Rhinitis, eczema, asthma and parental allergy were questionnaire-assessed. Results Of the 216 participants with rhinitis, 89 also had asthma and/or eczema. Participants with rhinitis that also had asthma or eczema were more likely to be IgE-sensitized (3.44, odds ratio, OR: 95% CI 1.62–7.30, adjusted for sex, age, mother’s allergy, total IgE and forced expiratory volume (FEV1)). The number of IgE-positive components was independently associated with atopic multimorbidity (1.11, OR: 95% Cl 1.01–1.21) adjusted for sex, age, mother’s allergy, total IgE and FEV1. When analysing different types of sensitization, the strongest association with atopic multimorbidity was found in participants that were IgE-sensitized both to perennial and seasonal allergens (4.50, OR: 95% CI 1.61–12.5). Maternal allergy (2.75, OR: 95% CI 1.15–4.46), high total IgE (2.38, OR: 95% CI 1.21–4.67) and lower FEV1 (0.73, OR: 95% CI 0.58–0.93) were also independently associated with atopic multimorbidity, while no association was found with any of the other inflammatory markers. Conclusion IgE polysensitization, to perennial and seasonal allergens, and levels of total IgE seem to be the main determinants of atopic multimorbidity in subjects with rhinitis. This indicates that disease-modifying treatment that targets IgE sensitization may be of value when decreasing the risk of developing atopic multimorbidity.

This study evaluated the inflammatory markers in prediabetes and newly diagnosed type 2 diabetes mellitus (T2DM). Inflammatory markers levels were analyzed using one-way analysis of covariance and the association with prediabetes or T2DM risks was examined by logistic regression models. Our data showed increased levels of hypersensitivity C-reactive protein (hs-CRP), interleukin (IL-4), IL-10, and tryptase in prediabetes subjects and hs-CRP, immunoglobulin E (IgE), IL-4, and IL-10 in T2DM subjects. We concluded that Hs-CRP, IgE, IL-4, IL-10, and tryptase were positively associated with prediabetes or T2DM. Further large prospective studies are warranted to assess a temporal relation between inflammatory biomarkers and incidence of prediabetes or T2DM and its associated chronic diseases.

Background: The presence of immunoglobulin E (IgE), which cross-reacts with allergen components, such as profilins, polcalcins, and cross-reacting carbohydrate determinants (CCD), creates a problem when selecting patients for allergen immunotherapy by using conventional methods. The aim of this study was to evaluate the prevalence of sensitization to profilins, polcalcins, and CCDs in patients with seasonal pollen allergic rhinitis. Methods: The study was performed on a group of 112 patients with seasonal pollen allergic rhinitis, ages 14 to 55 years, with sensitization to at least one seasonal allergen (IgE > 0.7 kUA/L). The presence of IgE sensitization to recombinant (r) Bet v 2, rPhl p 12, rBet v 4, rPhl p 7, and CCDs, in addition to rBet v 1, rPhl p 1, rPhl p 5, was evaluated by using a multiparameter immunoblot. Results: Among the studied patients, 64.3, 80.4, and 41.1% were sensitized to birch, timothy grass, and mugwort pollen, respectively. Sensitization to profilins rBet v 2/Phl p 12 was demonstrated in 28.6%, to polcalcins Bet v 4/Phl p 7 in 8.9%, and to CCDs in 25%. In 29.3%, serum IgE reactivity to any of the cross-reactive components could be demonstrated. Serum IgE reactivity to rBet v 2 was always accompanied by IgE reactivity to rPhl p 12, and IgE reactivity to rBet v 4 was always accompanied by IgE reactivity to rPhl p 7. Among the patients with pollinosis co-sensitized to at least two allergen sources according to extract-based diagnosis, possible false-positive results due to sensitization to cross-reactive components were detected in 17.9%. Conclusion: Evaluation of sensitization to cross-reacting components may be useful in evaluation of patients with pollen allergy who are being assessed for allergen immunotherapy to optimize the constitution of their immunotherapy vaccines.

Objective: In this study, we: (1) evaluated the correlation between total IgE and the presence of specific IgE; (2) compared the characteristics of patients with positive specific IgE to those with negative specific IgE; and, (3) analyzed the allergic testing results of patients on omalizumab and reported the effect of omalizumab on forced expiratory volume (FEV1) and asthma control test (ACT) results. Methods: Data from patients diagnosed with allergic asthma and seen at Florida Lung, Asthma & Sleep Specialists (FLASS) between January 2016 and June 2019 were analyzed. Parameters evaluated were total IgE, and levels of specific IgE to antigens in the ImmunoCAP test and skin prick test (SPT). Additional parameters for patients on omalizumab therapy for at least 6 months were FEV1, % predicted FEV1 and ACT results. Results: A total of 475 patients (114 males, 361 females) met the inclusion criteria. The mean age was 53 years (range: 17 to 89 years). Of these, 36 patients were not included in the analysis due to incomplete data. Mean total IgE was higher in patients with positive ImmunoCAP results compared to those with negative results (396 KU/L vs. 81.3 KU/L). There was a significant positive correlation between total IgE and levels of positive specific IgE in the ImmunoCAP test (p<0.0001, r=0.36, n=213 patients). The correlation between total IgE and levels of positive allergens in SPT was not significant (p=0.15, n=44 patients) Two positive reactions to allergens were seen in 22% of ImmunoCAP tests and 13% of SPT tests. There was no statistically significant improvement in FEV1 (p=0.097, CI -0.17 to 0.02) and % predicted FEV1 (p=0.109, CI -6.63 to 0.70) in patients who used omalizumab for at least 6 months. There was a statistically significant improvement in ACT scores (p=0.031, CI -4.21 to -0.21) in patients who used omalizumab for at least 6 months. Conclusion: Allergic asthma could be seen in patients who had an absence of specific IgE in ImmunoCAP and a negative reaction to SPT. The benefit of omalizumab therapy is not limited to allergic asthma patients with positive specific IgE.

BACKGROUND: Lymphocyte-to-C-reactive protein ratio (LCR) has been used as a post-surgical prognostic biomarker in patients with gastric and colorectal cancer. However, its relationship with early postoperative complications in these patients is unknown. In this study, we aimed to reveal the relationship between LCR and postoperative complications. METHODS: Eighty-one patients operated for stomach and colorectal cancer between January 2020 and August 2020 were prospectively analyzed. On preoperative and postoperative days 1, 3 and 5, other inflammatory parameters, mainly LCR, neutrophil lymphocyte ratio (NLR), were recorded. The patients were divided into two groups according to Clavien-Dindo classification as stage III and higher complications major, stage I-II/non-complication minor. RESULTS: Fifty seven patients were operated for colorectal cancer, 24 patients for gastric cancer. The mean age of the patients was 65.6 ± 12.6, 34.6% of them was women. Age, operation time and hospital stay were significantly different between the groups (p= 0.004, p= 0.002, p< 0.001). Major complications developed in 18 patients. On postoperative day 5, LCR found superior diagnostic accuracy in predicting major postoperative complications compared to other inflammatory markers. On the postoperative 5th day, the cut-off value of LCR was 0.0034, 88.8% (71.9–94.8) sensitivity, and 85.7% (73.6–95.4) selectivity. CONCLUSION: Among different inflammatory markers, postoperative LCR is a safe and effective predictor of postoperative complications, especially after gastric and colorectal cancer surgery on day 5.

AbstractThe systemic inflammatory response is known to be associated with poor outcomes in patients with various types of cancer. The C-reactive protein (CRP)/albumin (Alb) ratio (CAR) has been reported as a novel inflammation-based prognostic marker. We have evaluated the prognostic value of inflammatory markers for patients with oral squamous cell carcinoma (OSCC). The study population included 205 patients treated with OSCC between 2013 and 2018. The primary predictor variable was the inflammatory markers. The primary outcome variable was overall survival (OS). Univariate and multivariate analyses were performed using a Cox proportional hazards model to identify independent prognostic factors. The CAR had the highest area under the curve (AUC) values compared with other markers in the receiver operating characteristic (ROC) curve analysis. The cutoff value for CAR was 0.032 (AUC 0.693, P < 0.001). There was a significant difference in OS when patients were stratified according to CAR, with 79.1% for CAR < 0.032 and 35% for CAR ≥ 0.032 (P < 0.001). Cox multivariate analysis identified independent predictive factors for OS: age (hazard ratio [HR] 2.155, 95% confidence interval [CI] 1.262–3.682; P = 0.005), stage (HR 3.031, 95% CI 1.576–5.827; P = 0.001), and CAR (HR 2.859, 95% CI 1.667–4.904; P < 0.001). CAR (≥ 0.032 vs. < 0.032) is a good prognostic marker in patients with OSCC in terms of age and stage.

Patients with coronavirus disease 2019 (COVID-19) develop severe respiratory failure within a short period during the clinical course. It is essential to predict respiratory deterioration in the short term. We investigated the use of inflammatory markers to predict respiratory distress within three days from their analysis in COVID-19 patients. This retrospective observational study included 81 patients admitted with COVID-19. Patients were divided into two groups according to whether the maximum fraction of inspired oxygen (FiO2) for three days from the blood marker measurements was ≥0.4 (high FiO2 group; HFG) or <0.4 (low FiO2 group; LFG). Interleukin-6 (IL-6), C-reactive protein (CRP), lactate dehydrogenase (LDH), white blood cell, D-dimer, and creatinine levels were compared between the two groups. The levels of all markers were significantly higher in HFG patients. Areas under the receiver operating characteristic curve of IL-6, CRP, and LDH had high values of 0.85, 0.82, and 0.81, respectively. The odds ratio of IL-6 which was crude and adjusted for dexamethasone administration initiated before laboratory measurement, showed the high value of 29.1 (5.6–295.6) and 53.9 (4.5–3242.8), respectively. IL-6 can be used as a reliable marker for predicting respiratory illness within three days after assessment.

OBJECTIVE:To assess the changes in respiratory health from winter to summer seasons in a rural population.DESIGN:A longitudinal design was used in the study.SETTING:A population-based study was conducted as part of the Environmental Pesticide Exposure and Human Health component of the Prairie Ecosystem Study (PECOS) in southwestern Saskatchewan.PATIENTS:In the winter season, 358 patients participated in the study. Of these patients, 234 returned for the second assessment during the summer season. After excluding 34 children aged 17 years and under, 200 adult patients were available for analysis.MEASUREMENTS:Questionnaires were used to obtain information on demographic factors, smoking habits, occupational and environmental exposures, and respiratory conditions. Pulmonary function measurements were obtained using a volume displacement spirometer.RESULTS:Mean ages (± SD) of the 106 men and 94 women participating in the study were 50.1±13.3 and 49.0±13.1 years, respectively. Mean percentage changes in maximal midexpiratory flow rate from winter to summer assessments indicated an improvement for town residents and a decline for farm residents. Mean percentage changes in the ratio of forced expiratory volume in 1 s to forced vital capacity indicated an improvement for town residents who were not engaged in farming, and increasing declines for town residents engaged in farming, farm residents not engaged in farming and farm residents engaged in farming.CONCLUSIONS:Seasonal changes occurred in measurements of pulmonary function between winter and summer seasons; these changes may be related to the environmental or occupational exposures experienced by the participants during the study.

RationaleWe aimed to identify differentially methylated regions (DMRs) in cord blood DNA associated with childhood lung function, asthma and chronic obstructive pulmonary disease (COPD) across the life course.MethodsWe meta-analysed epigenome-wide data of 1688 children from five cohorts to identify cord blood DMRs and their annotated genes, in relation to forced expiratory volume in 1 s (FEV1), FEV1/forced vital capacity (FVC) ratio and forced expiratory flow at 75% of FVC at ages 7–13 years. Identified DMRs were explored for associations with childhood asthma, adult lung function and COPD, gene expression and involvement in biological processes.ResultsWe identified 59 DMRs associated with childhood lung function, of which 18 were associated with childhood asthma and nine with COPD in adulthood. Genes annotated to the top 10 identified DMRs were HOXA5, PAOX, LINC00602, ABCA7, PER3, CLCA1, VENTX, NUDT12, PTPRN2 and TCL1A. Differential gene expression in blood was observed for 32 DMRs in childhood and 18 in adulthood. Genes related with 16 identified DMRs were associated with respiratory developmental or pathogenic pathways.InterpretationOur findings suggest that the epigenetic status of the newborn affects respiratory health and disease across the life course.

Background. Waterpipe smoking in young individuals is increasing with limited studies addressing its respiratory health effects. The aim of the study was to determine the effect of waterpipe smoking on young adults’ lung functions. Spirometric parameters were compared between waterpipe smokers and nonsmokers. Methods. A comparative cross-sectional study of university students, including males and females, was conducted. An interviewer-administered questionnaire was used to record students’ characteristics. The spirometry test was performed to assess students’ lung functions; we recorded the forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), FEV1/FVC ratio, peak expiratory flow (PEF), and forced expiratory flow between 25 and 75% of FVC (FEF25–75%). Results. A total of 300 apparently healthy students (150 waterpipe smokers and 150 nonsmokers) were included in the study. Waterpipe smokers showed significantly lower values in FEV1, FEV1/FVC ratio, PEF, and FEF25–75% compared to the nonsmoker group (P<0.05 to P<0.001). The subgroup analysis on female students (50 WP smokers and 50 nonsmokers) showed a significant decrease in FEV1/FVC ratio, PEF, and FEF25–75% parameters (P<0.001). Conclusion. Waterpipe smoking is associated with reduced spirometric parameters in healthy young adults with relatively limited smoking years.
