    Urinary leukotriene E4 (ULTE4) may be a biomarker that distinguishes aspirin-intolerant asthma from other asthma subtypes. To estimate the diagnostic testing accuracy of ULTE4 as a marker of aspirin intolerance in patients with asthma using previously published studies. We identified relevant clinical studies from a systematic review of English and non-English articles using MEDLINE, EMBASE, and CENTRAL (inception to February 10, 2015). Articles were screened at the abstract and full-text level by 2 independent reviewers. We included previously published studies that analyzed ULTE4 in human subjects with asthma characterized as having or not having aspirin intolerance on the basis of a specified definition: convincing history of aspirin intolerance, positive aspirin challenge, or both as the criterion standard. Individual-level data points from all included studies were obtained and analyzed. The search strategy identified 867 potential articles, of which 86 were reviewed at the full-text level and 10 met criteria for inclusion. The sensitivity, specificity, positive predictive value, and negative predictive values of ULTE4 to determine aspirin intolerance in subjects with asthma were 0.55, 0.82, 0.75, and 0.66 (Amersham-enzyme immunoassay); 0.76, 0.77, 0.70, and 0.78 (Cayman-enzyme immunoassay); 0.70, 0.81, 0.86, and 0.79 (mass spectrometry); and 0.81,0.79, 0.65, and 0.88 (radioimmunoassay) at optimal thresholds of 192, 510, 167 to 173, and 66 to 69 pg/mg Cr, respectively. The diagnostic odds ratio for each methodology was 6.0, 11.9, 10.5, and 19.1, respectively. ULTE4 is a marker for aspirin-intolerant asthma and could potentially be used as a clinical test to identify the risk of aspirin intolerance in subjects with asthma.

    The pathogenesis of aspirin (acetylsalicylic acid, ASA)-intolerant urticaria (AIU) is still poorly understood but it has recently been suggested that it is associated with the overproduction of leukotriene (LT). This is supported by evidence that cyclooxygenase 2 inhibitor is given safely to patients with AIU. The present study was designed to investigate the role of genetic polymorphism of LT related genes in the pathogenesis of AIU via a case-control study. We screened single nucleotide pol...

    This review focuses on aspirin-exacerbated asthma (AEA). The review includes historical perspective of aspirin, prevalence, pathogenesis, clinical features and treatment of AEA. The pathogenesis of AEA involves the cyclooxygenase and lipooxygenase pathway. Aspirin affects both of these pathways by inhibiting the enzyme cycooxygenase-1 (COX-1). Inhibition of COX-1 leads to a decrease in prostaglandin E2 (PGE2). The decrease in PGE2 results in an increase in cysteinyl leukotrienes by the lipoo...

    Full Text Available This review focuses on aspirin-exacerbated asthma (AEA. The review includes historical perspective of aspirin, prevalence, pathogenesis, clinical features and treatment of AEA. The pathogenesis of AEA involves the cyclooxygenase and lipooxygenase pathway. Aspirin affects both of these pathways by inhibiting the enzyme cycooxygenase-1 (COX-1. Inhibition of COX-1 leads to a decrease in prostaglandin E2 (PGE2. The decrease in PGE2 results in an increase in cysteinyl leukotrienes by the lipooxygenase pathway involving the enzyme 5-lipooxygenase (5-LO. Leukotriene C4 (LTC4 synthase is the enzyme responsible for the production of leukotriene C4, the chief cysteinyl leukotriene responsible for AEA. There have been familial occurences of AEA. An allele of the LTC4 synthase gene in AEA is known as allele C. Allele C has a higher frequency in AEA. Clinical presentation includes a history of asthma after ingestion of aspirin, nasal congestion, watery rhinorrhea and nasal polyposis. Treatment includes leukotriene receptor antagonists, leukotriene inhibitors, aspirin desinsitaztion and surgery. AEA is the most well-defined phenotype of asthma. Although AEA affects adults and children with physician-diagnosed asthma, in some cases there is no history of asthma and AEA often goes unrecognized and underdiagnosed.

  8. Aspirin-Intolerant Asthma (AIA Assessment Using the Urinary Biomarkers, Leukotriene E4 (LTE4 and Prostaglandin D2 (PGD2 Metabolites

    Full Text Available The clinical syndrome of aspirin-intolerant asthma (AIA is characterized by aspirin/nonsteroidal antiinflammatory drug intolerance, bronchial asthma, and chronic rhinosinusitis with nasal polyposis. AIA reactions are evidently triggered by pharmacological effect of cyclooxygenase-1 inhibitors. Urine sampling is a non-invasive research tool for time-course measurements in clinical investigations. The urinary stable metabolite concentration of arachidonic acid products provides a time-integrated estimate of the production of the parent compounds in vivo. AIA patients exhibits significantly higher urinary concentrations of leukotriene E4 (LTE4 and 1,15-dioxo-9α-hydroxy-2,3,4,5-tetranorprostan-1,20-dioic acid (tetranor-PGDM, a newly identified metabolite of PGD2, at baseline. This finding suggests the possibility that increased mast cell activation is involved in the pathophysiology of AIA even in a clinically stable condition. In addition, lower urinary concentrations of primary prostaglandin E2 and 15-epimer of lipoxin A4 at baseline in the AIA patients suggest that the impaired anti-inflammatory elements may also contribute to the severe clinical outcome of AIA. During the AIA reaction, the urinary concentrations of LTE4 and PGD2 metabolites, including tetranor-PGDM significantly and correlatively increase. It is considered that mast cell activation probably is a pathophysiologic hallmark of AIA. However, despite the fact that cyclooxygenease-1 is the dominant in vivo PGD2 biosynthetic pathway, the precise mechanism underlying the PGD2 overproduction resulting from the pharmacological effect of cyclooxygenease-1 inhibitors in AIA remains unknown. A comprehensive analysis of the urinary concentration of inflammatory mediators may afford a new research target in elucidating the pathophysiology of AIA.

  9. Mechanisms of aspirin-sensitive asthma

    Full Text Available It is now widely accepted that aspirin, along with other non-steroidal anti-inflammatory drugs (NSAIDs, may precipitate asthma attacks in a minority of susceptible individuals. The syndrome is part of a mucosal inflammatory disease that typically affects the nasal, as well as the bronchial, mucosa and sometimes the gut and skin also. Although the mucosal cellular infiltrate in aspirin-sensitive asthma and rhinitis resembles that of asthma and rhinitis in general, there is evidence of increased expression of asthma-relevant cytokines, such as interleukin-5 and granulocyte–macrophage colony stimulating factor, and a more intense infiltrate of mast cells and eosinophils. One key feature of aspirin-sensitive asthma is thought to be the overproduction of cysteinyl leukotrienes, principally by these local mast cells and eosinophils, but whether this represents a fundamental abnormality or is simply a consequence of greater numbers and activation of inflammatory cells is unclear. Genetic polymorphisms of the leukotriene C4 synthase gene, which result in elevated expression of this enzyme, may also play a role. In addition, overexpression of cysteinyl leukotriene receptors, particularly CysLT1, may contribute to an enhanced response of local inflammatory and structural cells to cysteinyl leukotrienes. Aspirin challenge in these patients is accompanied by acute further elevation of the already elevated baseline cysteinyl leukotriene synthesis, a phenomenon that is most closely related to the ability of aspirin and related NSAIDs to inhibit the cyclooxygenase enzyme COX-1. The reason for this is unknown, although it has been suggested that the COX-1 product prostaglandin E2 (PGE2 serves as a ‘brake’ to leukotriene synthesis and that somehow this mechanism is deficient in aspirin-sensitive asthmatics. A better understanding of the pathogenesis of aspirin-sensitive asthma will undoubtedly lead to better approaches to treatment. Aside from the use of

    Background. Special regulatory role of eicosanoids has been postulated in aspirin-induced asthma. Objective. To investigate effects of aspirin on exhaled breath condensate (EBC) levels of eicosanoids in patients with asthma. Methods. We determined EBC eicosanoid concentrations using gas chromatography/mass spectrometry (GC-MS) and high-performance liquid chromatography/mass spectrometry (HPLC-MS2) or both. Determinations were performed at baseline and following bronchial aspirin challenge, in two well-defined phenotypes of asthma: aspirin-sensitive and aspirin-tolerant patients. Results. Aspirin precipitated bronchial reactions in all aspirin-sensitive, but in none of aspirin-tolerant patients (ATAs). At baseline, eicosanoids profile did not differ between both asthma groups except for lipoxygenation products: 5- and 15-hydroxyeicosatetraenoic acid (5-, 15-HETE) which were higher in aspirin-induced asthma (AIA) than inaspirin-tolerant subjects. Following aspirin challenge the total levels of cysteinyl-leukotrienes (cys-LTs) remained unchanged in both groups. The dose of aspirin had an effect on magnitude of the response of the exhaled cys-LTs and prostanoids levels only in AIA subjects. Conclusion. The high baseline eicosanoid profiling of lipoxygenation products 5- and 15-HETE in EBC makes it possible to detect alterations in aspirin-sensitive asthma. Cysteinyl-leukotrienes, and eoxins levels in EBC after bronchial aspirin administration in stable asthma patients cannot be used as a reliable diagnostic index for aspirin hypersensitivity.

    Thyroid antibodies are frequently observed in urticaria patients, but their roles in urticaria are not clearly elucidated. We investigated the role of serum specific IgE to thyroid peroxidase (TPO) in patients with aspirin intolerant acute urticaria (AIAU) and aspirin intolerant chronic urticaria (AICU). We recruited 59 AIAU and 96 AICU patients with 69 normal controls (NC). Serum specific IgE to TPO was measured by manual direct ELISA, and CD203c expressions on basophil with additions of TPO were measured to prove a direct role of TPO in effector cells. The prevalences of serum specific IgE to TPO were significantly higher in AIAU (15.2%) and AICU groups (7.5%) compared to NC (0%, P=0.018: P=0.013, respectively). Flow cytometry showed CD203c induction in a dose dependent manner with serial additions of TPO in some AIAU and AICU patients having high specific IgE to TPO. Our findings show that the prevalence of serum specific IgE to TPO was significantly higher in both AIAU and AICU patients than in NC. It is suggested that specific IgE to TPO play a pathogenic role in AIAU and AICU.

    Effective control of asthma is the primary goal of its treatment. Despite an improved understanding of asthma pathogenesis and accessibility of novel therapies, the rate of uncontrolled asthma remains high. To find potential factors associated with asthma control in patients with aspirin-exacerbated respiratory disease (AERD). Clinical data were collected from a specifically structured questionnaire. Demographics, a history of upper airway symptoms, asthma course, exacerbations expressed as emergency department (ED) visits/hospitalizations, and asthma treatment were considered. Spirometry, skin prick tests, total IgE concentration, and blood eosinophil count were evaluated. Asthma control was assessed through the Asthma Control Test (ACT). Out of 201 AERD patients, 41 (20.4%), 69 (34.3%), and 91 (45.3%) had controlled, partially controlled, and uncontrolled asthma, respectively. A multivariate ordered logistic regression analysis revealed that hospitalizations for asthma in the previous 12 months (OR 2.88; 95%CI, 1.11-7.46), ED visits for asthma throughout its duration (OR 1.05; 95%CI, 1.004-1.10), and total IgE concentration (OR 1.28; 95%CI, 1.02-1.60) were positively associated with poor asthma control, whereas FEV1 values (OR 0.98; 95%CI, 0.96-0.99) and medical care at a referential specialty clinic (OR 0.50; 95%CI, 0.27-0.95) were positively associated with good asthma control. The prevalence of uncontrolled asthma in AERD patients is high and similar to that observed in different asthmatic populations. Owing both to the specificity and complexity of the disease, AERD patients should stay under regular care of well experienced referential medical centers to ensure that this asthma phenotype is dealt with effectively.

    Dual antiplatelet therapy (DAT) with aspirin and clopidogrel is the standard regimen to achieve rapid platelet inhibition and prevent thrombotic events. Currently, little information is available regarding alternative antiplatelet therapy in patients with an allergy or intolerance to aspirin. Although cilostazol is already a common alternative to aspirin in clinical practice in China, its efficacy and safety remain to be determined. We retrospectively analyzed 613 Chinese patients who had undergone primary percutaneous coronary intervention (PCI). Among them, 405 patients received standard DAT (aspirin plus clopidogrel) and 205 patients were identified with intolerance to aspirin and received alternative DAT (cilostazol plus clopidogrel). There were no significant differences between the two groups in their baseline clinical characteristics. The main outcomes of the study included major adverse cardiac events (MACEs) and bleeding events during 12 months of follow-up. The MACEs endpoint was reached in 10 of 205 patients treated with cilostazol (4.9%) and in 34 of 408 patients treated with aspirin (8.3%). No statistically significant difference was observed in MACEs between the two groups. However, patients in the cilostazol group had less restenosis than did patients in the aspirin group (1.5% vs 4.9%, P=0.035). The occurrence of bleeding events tended to be lower in the cilostazol group (0.49% vs 2.7%, P=0.063). These clinical observations were further analyzed using network system pharmacology analysis, and the outcomes were consistent with clinical observations and preclinical data reports. We conclude that in Chinese patients with aspirin intolerance undergoing coronary stent implantation, the combination of clopidogrel with cilostazol may be an efficacious and safe alternative to the standard DAT regimen.

    Urinary leukotriene E4 (LTE4) is a well-validated marker of the cysteinyl leukotriene pathway, and LTE4 elevation has been described in conditions such as asthma, aspirin sensitivity, and chronic rhinosinusitis (CRS). There have been a number of reports investigating the role of spot urine LTE4 to predict aspirin sensitivity; however, variability in urinary LTE4 may affect the accuracy of this approach. Here, we explored the utility of 24-hour urinary LTE4 in 5 clinical diagnoses of allergic rhinitis, asthma, chronic rhinosinusitis with nasal polyps (CRSwNP), CRS without nasal polyps, and aspirin sensitivity. This was a retrospective review of patients who had 24-hour quantification of urinary LTE4 by a clinically validated liquid chromatography tandem mass spectrometry method and their assigned diagnoses after assessment and clinical care. Twenty-four-hour urinary LTE4 elevations were seen in those with asthma and those with CRSwNP but influenced by underlying aspirin sensitivity. Elevation in LTE4 was significant in those with CRSwNP after adjusting for aspirin sensitivity. Allergic rhinitis was not associated with elevated LTE4 excretion. Receiver operator characteristic analysis of 24-hour urinary LTE4 showed that a cutoff value of 166 pg/mg Cr suggested the presence of history of aspirin sensitivity with 89% specificity, whereas a cutoff value of 241 pg/mg Cr discriminated "challenge-confirmed" aspirin-sensitive subjects with 92% specificity. Elevated 24-hour excretion of urinary LTE4 is a reliable and simple test to identify aspirin sensitivity in patients with respiratory diagnoses.

    The prevalence and mean provocative dose of oral aspirin (MPDA) triggering respiratory reactions in people with asthma have been inconsistently reported, and the relationship between NSAID-exacerbated respiratory disease (NERD) and asthma morbidity was less well quantified. A systematic review was performed by identifying studies diagnosing NERD using blinded, placebo-controlled oral provocation challenge tests (OPCTs) or by self-reported history in people with asthma. Data were extracted, and effect estimates for changes in respiratory function, MPDA and asthma morbidity were pooled using random-effects meta-analysis. The prevalence of NERD in adults with asthma was 9.0% (95% CI 6-12%) using OPCTs and 9.9% (95% CI 9.4-10.5%) using self-reported history from questionnaires. The MPDA in adults with NERD was 85.8 mg (95% CI 73.9-97.6). In people with NERD, the risk of: uncontrolled asthma was increased twofold (RR 1.96 (95% CI 1.25-3.07)); severe asthma and asthma attacks was increased by 60% (RR 1.58 (95% CI 1.15-2.16) and RR 1.59 (95% CI 1.21-2.09), respectively); emergency room visits was increased by 80% (RR 1.79 (95% CI 1.29-2.49)); and asthma hospitalization was increased by 40% (RR 1.37 (95% CI 1.12-1.67)) compared to people with NSAID-tolerant asthma. Respiratory reactions triggered by oral aspirin in people with asthma are relatively common. At the population level, the prevalence of NERD was similar when measured using appropriately conducted OPCTs or by self-reported history. On average, respiratory reactions were triggered by clinically relevant doses of oral aspirin. Asthma morbidity was significantly increased in people with NERD who potentially require more intensive monitoring and follow-up. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are major drugs used in the treatment of inflammation and pain in a wide variety of disorders. The best-known mechanism of action of NSAIDs is the inhibition of prostaglandin synthesis as a result of their action on cyclooxygenase (COX) enzymes. However, data have been accumulating through the years indicating that NSAIDs also act on other targets in cell signaling. It has been established that NSAIDs induce anti-inflammatory effects independent of COX. Acetylsalicylic acid (ASA) and other inhibitors of COX induce severe bronchospasms and asthmatic attacks in a significant population of asthmatic patients. The etiology of ASA induced asthma is complex and not fully understood, but most evidence points towards an abnormality of arachidonic acid (AA) metabolism. Since doses of ASA necessary to treat chronic inflammatory diseases appeared much higher than those required to inhibit PG synthesis, COX-independent mechanisms of NSAIDs were postulated. Recently, we have shown that NSAIDs induced expression of heat shock proteins specially HSP70. Heat shock proteins (HSPs) are normal intracellular proteins that are produced in greater amounts when cells are subjected to stress or injury. Interestingly, a potential pathogenic role for heat shock proteins in diseases such as autoimmune disease, vascular disease has been reported. Because mast cells have been reported to play a role in the pathogenesis of ASA induced asthma, a link between heat shock proteins and this disease could postulated. In this review, an overview is given on aspirin-induced asthma and the cells and mediators that may play a role therein. Mast cell signaling with regard to interaction with NSAIDs and heat shock proteins (HSPs) and toll-like receptors (TLRs) is further highlighted.

    dipirona e ao álcool, respectivamente, em quase metade e um terço destes pacientes.Following aspirin introduction as medicine, several reports were described concerning adverse reactions after its ingestion. Widal et al. (1922¹ were the first investigators to associate Aspirin intolerance (AI with asthma and nasal polyps (NP followed by Samter & Beers (1967². Such intolerance was manifested mainly by nasal obstruction and/or bronchospasm related to the cyclooxygenase-1 (COX-1 inhibition and consequent overproduction of leukotrienes. This might also be triggered by the administration of other non-steroid anti-inflammatory drugs, acetaminophen, food dyes and additives and alcohol. AIM: To analyze the risks of the analgesics and anti-inflammatory drugs use in patients with eosinophilic nasal polyposis tolerant and intolerant to aspirin. STUDY DESIGN: Transversal cohort study. MATERIAL AND METHOD: 45 patients were selected # 15 suffering from eosinophilic nasosinusal polyposis, tolerant to aspirin (group TA; other 15 with eosinophilic nasosinusal polyposis associated with aspirin intolerance (group AI, and 15 patients without nasosinusal polyposis with septal deviation (control group. The presence of reaction to aspirin, dipyrone, acetaminophen, other non-steroids anti-inflammatory drugs, food dyes and additives, other drugs or chemical substances was detected by inquiry. To exclude aspirin intolerance in TA and control groups, oral provocation test with aspirin was carried out. RESULTS: Bronchospasm was the main aspirin reaction in patients suffering from eosinophilic nasosinusal polyposis and which also showed with ingestion of acetaminophen (20%, alcohol (27%, non-steroids anti-inflammatory drugs (60% and dipyrone (47%. CONCLUSION: In patients with eosinophilic nasosinusal polyposis associated with aspirin intolerance it is important to do the diagnosis of intolerance to other drugs. The use of dipyrone and alcohol is worth attention, once its intolerance was observed

    Aspirin-exacerbated respiratory disease (AERD) consists of a classic tetrad: moderate/severe asthma, chronic rhinosinusitis, nasal polyps, and intolerance to aspirin or other nonsteroidal anti-inflammatory drugs. Clinical control with drugs, surgery, and desensitization are treatment options. To evaluate the efficacy and tolerability of aspirin desensitization in patients with AERD. Periodic symptom assessment and endoscopy in patients with AERD undergoing surgery who were desensitized. Seventeen patients were desensitized. Eight patients completed the desensitization and were followed for a minimum of a one-year period (mean 3.1 years). These patients showed improvement in all symptoms. Moreover, surgical reassessment was not indicated in any of these patients and there was a decrease in costs with medication and procedures. Eight patients did not complete desensitization, mainly due to procedure intolerance and uncontrolled asthma, whereas another patient was lost to follow-up. Aspirin desensitization, when tolerated, was effective in patients with AERD and with poor clinical/surgical response.

    A 25-year-old woman was admitted to our hospital because of wheeze, dyspnea, nasal obstruction, epiphora, and ear fullness. These symptoms occurred 30 minutes after the intake of 200 mg of ibuprofen and 100 mg of norfloxacin, which had been prescribed by a local clinic for an upper respiratory tract infection. The patient had kept 20 hamsters indoors and a dog outside for 1 year and a half. During the 9 months prior to admission, she had experienced nocturnal asthmatic symptoms, which were controlled by oral theophylline on an as-needed basis. She had seasonal rhinitis, but no sinusitis or nasal polyps. Serum total IgE was 98 U/ml, and tests for specific IgE antibodies to hamster epithelium and dog epithelium were both positive (class 2). The provocative concentration of methacholine causing a 20% fall in FEV1 was 4.7 mg/ml. After removal of the hamsters from her home, the patient became asymptomatic without further medication, and her airway hyper-responsiveness was also alleviated. Although inhalation challenge with 5% tolmetin failed to induce a positive reaction, the diagnosis of aspirin-induced asthma was confirmed by single-blind oral challenge with 100 mg of ibuprofen. The patient exhibited mild airway responsiveness as well as mild sensitivity to nonsteroidal anti-inflammatory drugs, differing from the severe and intractable clinical features of typical aspirin-induced asthma.

    We previously reported that the ILVBL gene on chromosome 19p13.1 was associated with the risk for aspirin-exacerbated respiratory disease (AERD) and the percent decline of forced expired volume in one second (FEV1) after an oral aspirin challenge test. In this study, we confirmed the association between polymorphisms and haplotypes of the ILVBL gene and the risk for AERD and its phenotype. We recruited 141 AERD and 995 aspirin-tolerant asthmatic (ATA) subjects. All study subjects underwent an oral aspirin challenge (OAC). Nine single nucleotide polymorphisms (SNPs) with minor allele frequencies above 0.05, which were present in the region from 2 kb upstream to 0.5 kb downstream of ILVBL in Asian populations, were selected and genotyped. In an allelic association analysis, seven of nine SNPs were significantly associated with the risk for AERD after correction for multiple comparisons. In a codominant model, the five SNPs making up block2 (rs2240299, rs7507755, rs1468198, rs2074261, and rs13301) showed significant associations with the risk for AERD (corrected P = 0.001-0.004, OR = 0.59-0.64). Rs1468198 was also significantly associated with the percent decline in FEV1 in OAC tests after correction for multiple comparisons in the codominant model (corrected P = 0.033), but the other four SNPs in hapblock2 were not. To the best of our knowledge, this is the first report of an association between SNPs on ILVBL and AERD. SNPs on ILVBL could be promising genetic markers of this condition.

(1) To estimate urinary concentrations of BY and CY in asthmatic patients. (2) To investigate BY concentration in relation to urinary leukotriene E4 (LTE4) concentration in order to evaluate the activation of eosinophils in patients with aspirin-induced asthma (AIA). BY and CY were quantified with a gas chromatograph-mass spectrometer using (13)C-labelled compounds as internal standards. (1) Activation of eosinophils and neutrophils by immobilized IgG1 induced preferential formation of BY and CY, respectively. (2) A significantly higher concentration of BY was observed in the urine from asthmatic patients than in that from healthy control subjects (45+/-21.7 vs. 22.6+/-10.8 ng/mg-creatinine, Pinduced asthmatic patients, the concentration of BY in urine did not significantly change. No significant change was also observed in the ratio of BY concentration to total tyrosine concentration in plasma proteins. In contrast, the concentration of urinary LTE4 significantly increased after the intravenous aspirin challenge. Determination of BY and CY concentrations may be useful for monitoring the activation of eosinophils and neutrophils in asthmatic patients, respectively. After aspirin challenge of AIA patients, the increased concentration of urinary LTE4 did not accompany changes in BY concentration in both urine and plasma proteins. These results may preclude the activation of eosinophils after aspirin challenge in patients with AIA.

    2016-01-01

    Aspirin-exacerbated respiratory disease (AERD) is a late onset condition characterized by the Samter triad (aspirin sensitivity [as well as sensitivity to any nonselective cyclooxygenase inhibitor], nasal polyps, asthma) and additional features, including eosinophilic chronic rhinosinusitis, hypereosinophilia, anosmia, frequent absence of atopy, and, intolerance to ingestion of red wine and other alcoholic beverages. The diagnosis is rare, and, because of this, it is also often missed by physicians. However, it is highly overexpressed in patients with severe asthma (and severe chronic rhinosinusitis with nasal polyps), which makes its recognition essential. For this review, we considered mechanisms involved in the pathogenesis of this disease and discussed the clinical symptoms of AERD. We also discussed the role of aspirin desensitization in the treatment of AERD. Also, we considered medications (e.g, leukotriene modifiers) and surgical interventions that have a role in the treatment of AERD. PMID:28124651

    1978-08-01

    Among adult patients with bronchial asthma and/or allergic rhinitis undergoing allergological investigation with skin test, nasal provocation test and RAST, 1129 answered a questionaire regarding food sensitivity (FS). 276 (24%) of the patients reported some kind of allergic symptoms on eating or handling various foods, of which hazel nut, apple and shell fish were the most often named. Females reported FS more often than males. A correlation was found between birch pollen allergy and FS with nuts, apple, peach, cherry, pear, plum, carrot and new potato. The higher the degree of birch pollen allergy, according to skin test, RAST or provocation test, the higher the frequency of FS. A correlation was found too between acetylsalicylic acid intolerance and FS with some foods, e.g. nuts, strawberry, almond, green pepper, hip, chocolate, egg, cabbage, milk and wine. The connection between birch pollen allergy and FS is probably explained by the structural relationship between birch pollen allergen and some allergens of the foodstuffs, whereas the high incidence of FS in acetylsalicylic acid-intolerant patients is probably explained by additives in foods as well as salicylates or benzoates naturally occurring in some food.

    Full Text Available Abstract Asthma is the most common respiratory disorder in Canada. Despite significant improvement in the diagnosis and management of this disorder, the majority of Canadians with asthma remain poorly controlled. In most patients, however, control can be achieved through the use of avoidance measures and appropriate pharmacological interventions. Inhaled corticosteroids (ICSs represent the standard of care for the majority of patients. Combination ICS/long-acting beta2-agonists (LABA inhalers are preferred for most adults who fail to achieve control with ICS therapy. Allergen-specific immunotherapy represents a potentially disease-modifying therapy for many patients with asthma, but should only be prescribed by physicians with appropriate training in allergy. Regular monitoring of asthma control, adherence to therapy and inhaler technique are also essential components of asthma management. This article provides a review of current literature and guidelines for the appropriate diagnosis and management of asthma.

    Aspirin exacerbated respiratory disease (AERD) is characterized as adult onset asthma, nasal polyps, chronic rhinosinusitis, and hypersensitivity to a cyclooxygenase-1 (COX-1) inhibitor, viz aspirin or nonsteroidal antiinflammatory drugs (NSAIDs). The method for diagnosing AERD is with aspirin challenge, and treatment includes aspirin desensitization followed by continued daily aspirin. Although oral challenge has been the mainstay in the United States, lysyl-aspirin has been validated as a diagnostic tool for aspirin-sensitive asthma and will be discussed further in this article. The challenges with aspirin therapy surrounding endoscopy and perioperative aspirin therapy will be discussed. Additionally, daily aspirin therapy is not for everyone. Aspirin is relatively contraindicated in those with a history of gastrointestinal bleed and an absolute contraindication in pregnancy. Aspirin desensitization and subsequent treatment has been shown to be highly effective for AERD.

    Aspirin-induced asthma (AIA) and aspirin-induced urticaria/angioedema (AIU) are two major aspirin-related allergies. We summarize recent findings related to their molecular genetic mechanisms in order to identify genetic susceptibility markers for differentiating AIU and AIA. The overproduction of cysteinyl leukotriene has been suggested as a mechanism in both AIU and AIA. Increased expression of CYSLTR1 with CYLSTR1 and CYSLTR2 polymorphisms are new findings in AIA, while the ALOX5 promoter ...

    Experiments are described where the experimental conditions have been optimized to detect aspirin by MALDI mass spectrometry. Although protonated aspirin was not observed by MALDI, sodium and potassium aspirin adducts could be found. Significantly better signals could be obtained by using Rb and Cs salts as cationization sources. Quantum calculations were carried out to determine the structure and energetics of the Li, K, Rb, and Cs alkali--aspirin adducts.

    Full Text Available Non-steroidal anti-inflammatory drugs (NSAIDs inhibit COX enzyme activity, a significant mechanism of action of NSAIDs. Inflammation is associated with increasing cancer incidence. Recent pre-clinical and clinical studies have shown that NSAID treatment could cause an anti-tumour effect in cancers. Such studies are lengthy and expensive. The present study, however, examined DNA damage in the Comet and micronucleus assays in peripheral blood lymphocytes of patients with respiratory diseases and healthy individuals using the nanoparticle (NP and bulk versions of the NSAIDs, aspirin and ibuprofen. Lymphocytes are suitable surrogate cells for cancers and other disease states. DNA damage decreased in lymphocytes from healthy individuals, asthma, COPD and lung cancer patient groups after treatment with aspirin nano-suspension (ASP N and ibuprofen nano-suspension (IBU N compared to their bulk version (micro-suspension in both assays. However, when ASP N was compared to untreated lymphocytes in all groups in the Comet assay, DNA damage significantly decreased in all groups, except the asthma group. When IBU N was compared to untreated lymphocytes, in healthy individuals and the lung cancer group, DNA damage decreased, but increased in asthma and COPD groups. Similarly, micronuclei (MNi increased after ASP N and IBU N in the healthy individual and lung cancer groups, and decreased in asthma and COPD groups. Also shows that whilst there are basic similarities with different genetic endpoints in terms of nano and bulk forms, but highlights some differences between the disease states examined. Furthermore, lymphocyte responses after IBU N and ibuprofen bulk were investigated by patch-clamp experiments demonstrating that IBU N inhibited ion channel activity by 20%. This molecular epidemiology approach mirrors pre-clinical and clinical findings, and provides new information using nanoparticles.

    2010-01-01

    Full Text Available Disaccharide intolerance presents a pathogenic heterogeneous and most complex clinical entity. It usually occurs due to primary or secondary deficit of disaccharide activity, and rarely because of disorders of absorption or monomer metabolism. Symptomatology of disaccharide maldigestion and/or malabsorption depends on the severity of the basic disorder, the level of its overload and the patient’s age. In the youngest children, due to a rapid gastrointestinal transit and a low compensatory capacity of the colon, osmotic-fermentative diarrhoea forms the basis of clinical features. Diarrhoeal disorder can be occasionally so intensive that it disturbs not only water and electrolytic balance, but also the nutritive status of the child. In older children and adults, as well as in milder forms of the disorder, the symptomatology, most often without diarrhoea, is dominated by abdominal colic, loud peristaltic sounds, meteorism and increased flatulence. Metabolic disorders followed by conversion disorders of galactose and fructose into glucose are characterized by a hypoglycaemic crisis, as well as by various multisystemic damages due to the deposit of toxic metabolic products. The diagnosis of gastrointestinal forms of disaccharide intolerance is based on the pathologic clinical and laboratory response during the overload test, while that of the metabolic form is based on the confirmed presence of specific enzyme and/or genetic defect. Treatment of disaccharide intolerance is based on the elimination diet. Besides, in the secondary forms of the disorder, it is also necessary to apply the treatment of the basic disease.

    2007-07-01

    To evaluate and provide management strategies for patients with aspirin or nonselective nonsteroidal antiinflammatory drug (NSAID) sensitivity. Literature retrieval was accessed through MEDLINE (1966-March 2007) using the terms acetaminophen, aspirin, antiinflammatory agents nonsteroidal, urticaria, angioedema, asthma, leukotriene antagonists, desensitization, and tacrolimus. Article references retrieved were hand-searched for other relevant articles. All studies published in English were evaluated. Studies, review articles, and commentaries on aspirin-induced asthma and aspirin- or NSAID-induced urticaria/angioedema were included in the review. Aspirin sensitivity is most often manifested as respiratory reactions (eg, bronchospasm, profuse rhinorrhea, conjunctival injection) or urticaria/angioedema. The primary mechanism is believed to be inhibition of the cyclooxygenase 1 (COX-1) enzyme; as such, patients with aspirin sensitivity often display cross-reactions to nonselective NSAIDs that inhibit the COX-1 enzyme. Management strategies include avoidance of aspirin and cross-reacting nonselective NSAIDs. However, desensitization to aspirin is a viable option for patients with aspirin-induced respiratory reactions, especially for those who require aspirin for thromboembolic prophylaxis. Aspirin desensitization is maintained indefinitely with a daily aspirin dose. There is limited evidence of the use of leukotriene modifiers in preventing aspirin-induced asthma. COX-2 selective NSAIDs, especially in patients with aspirin-induced asthma, have not been found to cross-react. However, approximately 4% of patients with a history of aspirin-induced skin reactions may experience a cutaneous reaction following a challenge to a COX-2 selective NSAID. Since acetaminophen is a weak inhibitor of the COX-1 enzyme, patients with aspirin-induced asthma should not take more than 1000 mg of acetaminophen in a single dose. Management of patients with aspirin/NSAID sensitivity includes

    2013-05-01

    Various hypersensitivity reactions have been reported with aspirin and nonsteroidal anti-inflammatory drugs. Hypersensitivity can occur regardless of a chemical drug structure or its therapeutic potency. Allergic conditions include aspirin-exacerbated respiratory disease (AERD or aspirin-induced asthma), aspirin-induced urticaria/angioedema (AIU), and anaphylaxis. Several genetic studies on aspirin hypersensitivity have been performed to discover the genetic predisposition to aspirin hypersensitivity and to gain insight into the phenotypic diversity. This article updates data on the genetic mechanisms that govern AERD and AIU and summarizes recent findings on the molecular genetic mechanism of aspirin hypersensitivity.

    Many folk remedies used since pre-historic times have depended upon salicylates for their effect. One hundred years ago aspirin was formulated from salicylic and acetic acids. It was the first drug to be synthesised and its formulation is regarded as the foundation of the modern pharmaceutical industry. The benefit of low-dose aspirin as a prophylactic after a thrombotic event was first reported 25 years ago. Its use after coronary or cerebral thrombosis is virtually mandatory, unless there are signs of intolerance. A 'loading dose' of soluble aspirin should be given on first contact with a patient who may be suffering from myocardial infarction. Patients considered to be at increased risk of a vascular event should also be advised to carry their own aspirin and, if they experience sudden severe chest pain, to chew and swallow a 300 mg tablet or a soluble preparation immediately. The current phase of the aspirin story is, however, not over, and its possible value in a variety of conditions, including dementia and certain cancers, seems likely to ensure that it will long continue to play a remarkable part in clinical practice.

    Full Text Available Aspirin exacerbated respiratory disease (AERD is characterized by chronic hyperplastic rhinosinusitis, nasal polyposis, asthma, and aspirin sensitivity. The mechanisms which produce these manifestations of intolerance are not fully defined, current research focuses on cyclooxygenase 1 (COX-1 inhibition, metabolism of arachidonic acid, and the COX pathway to the lipoxygenase (LO route, inducing increased synthesis of leukotrienes (LT. The biological plausibility of this model has led to the search for polymorphisms in genes responsible for proinflammatory cytokines synthesis, such as IL1B and IL8. We performed a genetic association study between IL8-251 (rs4073 and IL1B-511 (rs16944 polymorphisms in AERD, aspirin-tolerant asthma (ATA, and healthy control subjects. Using allelic discrimination by real-time PCR, we found statistically nonsignificant associations between AERD, ATA, and healthy control subjects for the GG and GA genotypes of IL1B (rs16944. Interestingly, the AA genotype showed an increased frequency in the AERD patients versus the ATA group (GF = 0.19 versus 0.07, =0.018, OR 2.98, and 95% CI 1.17–7.82. This is the first observation that IL1B polymorphisms are involved in AERD. Thus, future studies must investigate whether interleukin-1 is released in the airways of AERD patients and whether it relates to genetic polymorphisms in the IL1B gene.

    Theophylline is commonly used to treat severe asthma and chronic obstructive pulmonary disease (COPD) characterized by non-eosinophilic inflammation. Acetyl salicylic acid (ASA) is one of the most widely used medications worldwide, but up to 20% of patients with asthma experience aggravated respiratory symptoms after taking ASA. Here we evaluated the adverse effect of ASA on the therapeutic effect of theophylline in mice with non-eosinophilic asthma. A non-eosinophilic asthma mouse model was induced by airway sensitization with lipopolysaccharide-containing allergen and then challenged with allergen alone. Therapeutic intervention was performed during allergen challenge. Theophylline inhibited lung inflammation partly induced by Th1 immune response. ASA attenuated the beneficial effects of theophylline. However, co-administration of the ASA metabolite salicylic acid (SA) showed no attenuating effect on theophylline treatment. The therapeutic effect of theophylline was associated with increase in cAMP levels, which was blocked by co-treatment of theophylline and ASA. ASA co-treatment also attenuated the anti-inflammatory effects of a specific phosphodiesterase 4 inhibitor. These results demonstrate that ASA reverses anti-inflammatory effects of theophylline, and that ASA exerts its adverse effects through the inhibition of cAMP production. Our data suggest that ASA reverses lung inflammation in patients taking theophylline, although clinical evidence will be needed.

    Theophylline is commonly used to treat severe asthma and chronic obstructive pulmonary disease (COPD) characterized by non-eosinophilic inflammation. Acetyl salicylic acid (ASA) is one of the most widely used medications worldwide, but up to 20% of patients with asthma experience aggravated respiratory symptoms after taking ASA. Here we evaluated the adverse effect of ASA on the therapeutic effect of theophylline in mice with non-eosinophilic asthma. A non-eosinophilic asthma mouse model was induced by airway sensitization with lipopolysaccharide-containing allergen and then challenged with allergen alone. Therapeutic intervention was performed during allergen challenge. Theophylline inhibited lung inflammation partly induced by Th1 immune response. ASA attenuated the beneficial effects of theophylline. However, co-administration of the ASA metabolite salicylic acid (SA) showed no attenuating effect on theophylline treatment.

    In subjects with non-steroidal anti-inflammatory drugs (NSAIDs)- exacerbated respiratory disease (NERD) symptoms are triggered by acetyl salicylic acid (ASA) and other strong COX-1 inhibitors, and in some cases by weak COX-1 or by selective COX-2 inhibitors. The mechanism involved is related to prostaglandin pathway inhibition and leukotriene release. Subjects who react to a single NSAID and tolerate others are considered selective responders, and often present urticaria and/or angioedema and anaphylaxis (SNIUAA). An immunological mechanism is implicated in these reactions. However, anecdotal evidence suggests that selective responders who present respiratory airway symptoms may also exist. Our objective was to determine if subjects might develop selective responses to NSAIDs/paracetamol that manifest as upper/lower airways respiratory symptoms. For this purpose, we studied patients reporting asthma and/or rhinitis induced by paracetamol or a single NSAID that tolerated ASA. An allergological evaluation plus controlled challenge with ASA was carried out. If ASA tolerance was found, we proceeded with an oral challenge with the culprit drug. The appearance of symptoms was monitored by a clinical questionnaire and by measuring FEV1 and/or nasal airways volume changes pre and post challenge. From a total of 21 initial cases, we confirmed the appearance of nasal and/or bronchial manifestations in ten, characterized by a significant decrease in FEV1% and/or a decrease in nasal volume cavity after drug administration. All cases tolerated ASA. This shows that ASA tolerant subjects with asthma and/or rhinitis induced by paracetamol or a single NSAID without skin/systemic manifestations exist. Whether these patients represent a new clinical phenotype to be included within the current classification of hypersensitivity reactions to NSAIDs requires further investigation.

    Dietary intolerances to fructose, fructans and FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides And Polyols) are common, yet poorly recognized and managed. Over the last decade, they have come to the forefront because of new knowledge on the mechanisms and treatment of these conditions. Patients with these problems often present with unexplained bloating, belching, distension, gas, abdominal pain or diarrhea. Here, we have examined the most up-to-date research on these food-related intolerances, discussed controversies, and have provided some guidelines for the dietary management of these conditions. Breath testing for carbohydrate intolerance appears to be standardized and essential for the diagnosis and management of these conditions, especially in the Western population. While current research shows that the FODMAP diet may be effective in treating irritable bowel syndrome, additional research is needed to identify more foods items that are high in FODMAPs, and to assess the long-term efficacy and safety of dietary interventions.

    2014-01-01

    The pathogenesis of aspirin-exacerbated respiratory disease (AERD) is thought to be based on, mainly, overproduction of eicosanoid lipid mediators and on defective anti-inflammatory regulators. Aspirin desensitization treatment, the mainstay of controlling asthma and rhinitis in AERD patients, however, is the least understood aspect of the disease. The study was designed to determine the effect of aspirin desensitization on T-lymphocyte cytokine expression and on plasma lipoxin levels in AERD. Spirometry, skin-prick test and asthma control test were documented and intracellular cytokine expression in T lymphocytes and plasma lipoxin levels were measured in 23 AERD patients, 17 aspirin-tolerant asthmatic (ATA) patients, and 16 healthy controls. In the AERD group nasal symptom and smell scores were assessed. Of the 23 AERD patients 15 accepted to undergo aspirin desensitization protocol and 14 of them were desensitized successfully. In the desensitized AERD group, cytokine and lipoxin measurements were repeated after 1-month aspirin treatment. CD4(+) IL-10 levels were higher in AERD patients than in healthy controls and CD4(+) interferon (IFN) gamma levels were higher in AERD and ATA patients than in controls. Plasma lipoxin-A4 and 15-epi-lipoxin-A4 levels were similar among the three study groups. In the AERD group, subjects underwent aspirin desensitization followed by a 1-month aspirin treatment. Clinical parameters improved and CD4(+) IFN-gamma levels decreased significantly. No significant change in lipoxin levels was recorded. CD4(+) IFN-gamma and CD4(+) IL-10 levels in AERD patients after 1-month aspirin desensitization treatment were similar to the healthy controls. The study confirms aspirin desensitization is effective clinically in AERD patients and suggests that IFN gamma and IL-10 expression in CD4(+) T lymphocytes may be related to the mechanism of action.

    Full Text Available Adult bronchial asthma (hereinafter, asthma is characterized by chronic airway inflammation, reversible airway narrowing, and airway hyperresponsiveness. Long-standing asthma induces airway remodeling to cause an intractable asthma. The number of patients with asthma has increased, while the number of patients who die from asthma has decreased (1.7 per 100,000 patients in 2009. The aim of asthma treatment is to enable patients with asthma to lead a healthy life without any symptoms. A partnership between physicians and patients is indispensable for appropriate treatment. Long-term management with agents and elimination of causes and risk factors are fundamental to asthma treatment. Four steps in pharmacotherapy differentiate mild to intensive treatments; each step includes an appropriate daily dose of an inhaled corticosteroid (ICS, varying from low to high doses. Long-acting β2 agonists (LABA, leukotriene receptor antagonists, and theophylline sustained-release preparation are recommended as concomitant drugs, while anti-IgE antibody therapy is a new choice for the most severe and persistent asthma. Inhaled β2 agonists, aminophylline, corticosteroids, adrenaline, oxygen therapy, etc., are used as needed against acute exacerbations. Allergic rhinitis, chronic obstructive pulmonary disease (COPD, aspirin induced asthma, pregnancy, and cough variant asthma are also important factors that need to be considered.

  11. [Fructose and fructose intolerance].

    Although fructose was discovered in 1794, it was realised in recent decades only that its malabsorption can lead to intestinal symptoms while its excessive consumption induces metabolic disturbances. Fructose is a monosaccharide found naturally in most fruits and vegetables. Dietary intake of fructose has gradually increased in the past decades, especially because of the consumption of high fructose corn syrup. With its 16.4 kg/year consumption, Hungary ranks secondly after the United States. Fructose is absorbed in the small intestine by facilitated transport mediated by glucose transporter proteins-2 and -5, and arrives in the liver cells. Here it is transformed enzymatically into fructose-1-phosphate and then, fructose-1,5-diphosphate, which splits further into glyceraldehyde and dihydroxyacetone-phosphate, entering the process of glycolysis, triglyceride and uric acid production. The prevalence of fructose intolerance varies strongly, depending on the method used. The leading symptoms of fructose intolerance are similar, but less severe than those of lactose intolerance. Multiple secondary symptoms can also occur. A symptom-based diagnosis of fructose intolerance is possible, but the gold standard is the H 2 breath test, though this is less accurate than in lactose testing. Measuring fructosaemia is costly, cumbersome and not widely used. Fructose intolerance increases intestinal motility and sensitivity, promotes biofilm formation and contributes to the development of gastrooesophageal reflux. Long-term use of fructose fosters the development of dental caries and non-alcoholic steatohepatitis. Its role in carcinogenesis is presently investigated. The cornerstone of dietary management for fructose intolerance is the individual reduction of fructose intake and the FODMAP diet, led by a trained dietetician. The newly introduced xylose-isomerase is efficient in reducing the symptoms of fructose intolerance. Orv. Hetil., 2016, 157(43), 1708-1716.

  12. Paradoxical Effect of Aspirin

    Full Text Available Low-dose aspirin is an important therapeutic option in the secondary prevention of myocardial infarction (MI and ischemic stroke, basedon its unique cost-effectiveness and widespread availability. In addition, based on the results of a number of large studies, aspirin is also widely used in the primary prevention of MI. This paper provides an update of the available data to offer greater clarity regarding the risks of aspirin with respect to hemorrhagic stroke. In the secondary prevention of cardiovascular, cerebrovascular, and ischemic events, the evidence supports that the benefits of aspirin treatment significantly outweigh the risk of a major hemorrhage. When considering whether aspirin is appropriate, the absolute therapeutic cardiovascular benefits of aspirin must be balanced with the possible risks associated with its use, being hemorrhagic stroke. Regarding these clinical facts, normal, COX 1 −/−, and COX 2 −/− mice were treated with a wide range of doses of aspirin and studied by induced hemorrhagic time. The results outlined three major conclusions: high doses of aspirin induce hemorrhage, while low doses of aspirin do not. In the absence of COX 1, ultra low doses of aspirin produce an antihemorrhagic effect not observed with intermediate doses. The absence of COX 2 induced a hemorrhagic effect that needs further research, probably originated in compensatory phenomena.

    Aspirin reduces the risk of nonfatal myocardial infarction and stroke, and the risk of colorectal cancer. Aspirin increases the risk of gastrointestinal and intracranial bleeding. The best available evidence supports initiating aspirin in select populations. In 2016, the US Preventive Services Task Force recommended initiating aspirin for the primary prevention of both cardiovascular disease and colorectal cancer among adults ages 50 to 59 who are at increased risk for cardiovascular disease. Adults 60 to 69 who are at increased cardiovascular disease risk may also benefit. There remains considerable uncertainty about whether younger and older patients may benefit.

    Colorectal cancer is a worldwide public health problem. Aspirin has been identified as a protective factor against the apparition of colorectal cancer. There are several mechanisms about the actions by aspirin on colorectal tumorogenesis. These are not perfectly known nowadays. On one hand, there are direct mechanisms on colorectal mucosa, on the other hand there are indirect mechanisms through platelet functions. Aspirin also plays a role by its anti-inflammatory action and the stimulation of antitumor immunity. Several studies show that long-term treatment with low-doses of aspirin decreases the incidence of adenomas and colorectal cancers. In the United States, aspirin is currently recommended for primary prevention of the risk of colorectal cancer in all patients aged 50 to 59, with a 10-year risk of cardiovascular event greater than 10 %. However, primary prevention with aspirin should not be a substitute for screening in colorectal cancer. Furthermore, aspirin seems to be beneficial when used in post-diagnosis of colorectal cancer. It could actually decrease the risk of metastasis in case of a localized colorectal cancer, and increase the survival in particular, concerning PIK3CA mutated tumors. The association of aspirin with neoadjuvant treatment of colorectal cancer by radiochimiotherapy seems to have beneficial effects. French prospective randomized study is currently being conducted to investigate postoperative aspirin in colorectal cancers with a PIK3CA mutation. Copyright © 2017 Société Française du Cancer.

    1995-05-01

    Smokers have recently been shown to be insulin resistant and to exhibit several characteristics of the insulin resistance syndrome (IRS). In this study, we assessed fasting and postprandial lipid levels in healthy, normolipidaemic, chronic smokers and a matched group of non-smoking individuals. A standardized mixed meal (containing 3.78 MJ and 51 g of fat) was given in the morning after an overnight fast. The smokers were either abstinent from tobacco for 48 h or were allowed to smoke freely, including being allowed to smoke six cigarettes during the study. Twenty-two middle-aged, healthy male subjects, nine habitual smokers and 13 non-smoking control subjects, were recruited to the study. The smokers had all been smoking at least 10 cigarettes per day for at least 10 years. The smokers exhibited a lipid intolerance in that their postprandial increase in triglyceride levels was more than 50% higher than in the non-smokers' group. This lipid intolerance could not be discerned in the postabsorptive state because the fasting triglyceride levels were the same in both groups, while the smokers had significantly lower high-density lipoprotein (HDL) cholesterol. The peak postprandial triglyceride level correlated closely and negatively with fasting HDL cholesterol, indicating an impaired lipolytic removal capacity in smokers. Healthy, normotriglyceridaemic smokers exhibit an abnormal postprandial lipid metabolism consistent with lipid intolerance. It is suggested that postprandial hyperlipidaemia is a characteristic trait of the insulin resistance syndrome and that the defect in lipid removal is related to the low HDL cholesterol in this syndrome. The insulin resistance syndrome is likely to be an important reason for the increased propensity for cardiovascular disease in smokers.

    Tartrazine is the best known and one of the most commonly used food additives. Food colorants are also used in many medications as well as foods. There has been conflicting evidence as to whether tartrazine causes exacerbations of asthma with some studies finding a positive association especially in individuals with cross-sensitivity to aspirin. To assess the overall effect of tartrazine (exclusion or challenge) in the management of asthma. A search was carried out using the Cochrane Airways Group specialised register. Bibliographies of each RCT was searched for additional papers. Authors of identified RCTs were contacted for further information for their trials and details of other studies. RCTs of oral administration of tartrazine (as a challenge) versus placebo or dietary avoidance of tartrazine versus normal diet were considered. Studies which focused upon allergic asthma, were also included. Studies of tartrazine exclusion for other allergic conditions such as hay fever, allergic rhinitis and eczema were only considered if the results for subjects with asthma were separately identified. Trials could be in either adults or children with asthma or allergic asthma (e.g. sensitivity to aspirin or food items known to contain tartrazine). Study quality was assessed and data abstracted by two reviewers independently. Outcomes were analysed using RevMan 4.1.1. Ninety abstracts were found, of which 18 were potentially relevant. Six met the inclusion criteria, but only three presented results in a format that permitted analysis and none could be combined in a meta-analysis. In none of the studies did tartrazine challenge or avoidance in diet significantly alter asthma outcomes. Due to the paucity of available evidence, it is not possible to provide firm conclusions as to the effects of tartrazine on asthma control. However, the six RCTs that could be included in this review all arrived at the same conclusion. Routine tartrazine exclusion may not benefit most patients

    Laidlaw, Tanya M; Cahill, Katherine N

    Aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) are some of the most common culprits of drug-induced hypersensitivity reactions, and can lead to a wide array of adverse effects. The accurate and timely diagnosis of aspirin and NSAID-induced hypersensitivity reactions is important for both patient safety and for the initiation of appropriate disease-specific management and treatment. Because there are no reliably validated in vitro tests available, aspirin and NSAID challenges are considered to be the criterion standard for the diagnosis of these hypersensitivity reactions, though in some patients the diagnosis can be made on the basis of a clear clinical history.

    Full Text Available Clinical utility of aspirin (acetylsalicylic acid, ASA is one of the more important issues in the primary and secondary prevention of cardiovascular disease. The present paper provides analysis of aspirin history, mechanisms of its antiplatelet activity, and expediency of the use of low- and high-dose aspirin in the groups including patients after myocardial revascularization, and requiring secondary prevention of stroke. Also gender-specific aspirin properties were mentioned, highlighting the especially important role of aspirin in women at the age of >65 years, and its utility in all women, irrespectively of age, and those who are at high risk of cardiovascular disease, including atherosclerosis-related cardiovascular disease. Moreover, the mechanisms of aspirin resistance, characterized by inability of aspirin to prevent thromboembolic complications or inadequate platelet inhibition showed in laboratory results, were mentioned. Prevalence of resistance in aspirin-treated patients is estimated to be between 1 and 68%. Stress was also put on the aspirin safety, associated with prophylaxis of peptic ulcer disease, which can be achieved i.e. by the use of the enteric-coated aspirin. This form of aspirin is associated with lower risk of gastrointestinal mucosae damage and bleeding from the gastrointestinal tract. At the end of the article, the importance of the adherence to therapeutic guidelines of aspirin use, including assessment of variation in aspirin bioavailability associated with improper dosing and altered absorption in the gastrointestinal tract, was stressed.

    Aspirin desensitization followed by maintenance therapy effectively improves symptom control in patients with aspirin exacerbated respiratory disease (AERD). The majority of current desensitization protocols use 3-hour dosing intervals and often require 2 to 3 days to complete. We evaluated hourly dose escalations in a subset of patients with chronic rhinosinusitis, nasal polyps, and asthma who historically reacted to aspirin within 1 hour or were avoiding aspirin with the goal of developing a safe and efficient desensitization protocol. Fifty-seven aspirin desensitizations were performed under the hourly protocol. All patients had refractory nasal polyposis as an indication for aspirin desensitization. The clinical characteristics of each subject were analyzed in relation to aspects of his or her reactions during the procedure. Ninety-eight percent of study patients were successfully treated under the hourly protocol, including those with a history of severe reactions and intubation. None required further medication than is available in an outpatient allergy clinic. A total of 96% of reactors recorded a bronchial or naso-ocular reaction within 1 hour of the preceding dose. Of the total patients on this protocol, 40% were able to complete the procedure in a single day, and 60% within 2 days. Patients with AERD who have a history of symptoms less than 1 hour after aspirin exposure can be safely desensitized with a 1-hour dose-escalation protocol that can often be completed in a single day.

    Full Text Available Hereditary fructose intolerance, the prevalence of which is 1 : 20,000 population, is diagnosed much less frequently than is found in child and adult populations. Presented pathology is caused by a deficiency in ferment aldolase B and block of fructose transformation in the gastrointestinal tract with the accumulation of unprocessed fructose in the intestine, manifesting by characteristic symptom and numerous biochemical changes in the body. The disease is asymptomatic until a person begins to use fructose, sucrose or sorbitol. This article describes the fructose metabolism, genetic aspects of the discussing disease, the diversity of its clinical manifestations. The authors presented modern diagnostic criteria and international approaches to diet therapy.

    The place of aspirin in primary prevention remains controversial, with North American and European organizations issuing contradictory treatment guidelines. More recently, the U.S. Preventive Services Task Force recommended "initiating low-dose aspirin use for the primary prevention of cardiovascular disease (CVD) and colorectal cancer in adults aged 50 to 59 years who have a 10% or greater 10-year CVD risk, are not at increased risk for bleeding, have a life expectancy of at least 10 years, and are willing to take low-dose aspirin daily for at least 10 years." This recommendation reflects increasing evidence for a chemopreventive effect of low-dose aspirin against colorectal (and other) cancer. The intent of this paper is to review the evidence supporting a chemopreventive effect of aspirin, discuss its potential mechanism(s) of action, and provide a conceptual framework for assessing current guidelines in the light of ongoing studies.

    2013-03-06

    Banded spherulites of aspirin have been crystallized from the melt in the presence of salicylic acid either generated from aspirin decomposition or added deliberately (2.6-35.9 mol %). Scanning electron microscopy, X-ray diffraction analysis, and optical polarimetry show that the spherulites are composed of helicoidal crystallites twisted along the growth directions. Mueller matrix imaging reveals radial oscillations in not only linear birefringence, but also circular birefringence, whose origin is explained through slight (∼1.3°) but systematic splaying of individual lamellae in the film. Strain associated with the replacement of aspirin molecules by salicylic acid molecules in the crystal structure is computed to be large enough to work as the driving force for the twisting of crystallites.

    The use of aspirin in coronary artery disease and address the unmet need of aspirin therapy in patients with history of hypersensitivity reactions to aspirin (acetylsalicylic acid; ASA) or other nonsteroidal inflammatory drugs (NSAIDs). Aspirin hypersensitivity is reported in 1.5% of patients with cardiovascular disease. However, many of those labeled as allergic to aspirin had experienced side-effects and could be safely treated with aspirin. Those with true hypersensitivity reactions were often not placed on appropriate antiplatelet therapy. A number of protocols of varying complexity exist in the literature for aspirin desensitization. The focus of this review is to identify the types of aspirin reactions that can occur and provide a rational approach to oral aspirin challenge and desensitization. In summary, with rare exceptions, patients with a history of 'aspirin/NSAID allergy' who need ASA for cardiovascular issues will be able to safely take aspirin either after a graded challenge or desensitization providing a central role of the allergist in the management of these patients.

    There are currently no diagnostic methods in vitro for aspirin-induced chronic urticaria (AICU) except for the provocation test in vivo. To identify disease markers for AICU, we investigated the single nucleotide polymorphism (SNP) of the promoter loci of high-affinity IgE receptor (FcεRIα) and CD203c expression level in Chinese patients with AICU. We studied two genotypic and allelic frequencies of rs2427827 (–344C/T) and rs2251746 (–66T/C) gene polymorphisms of FcεRIα in 20 patients with AICU, 52 subjects with airway hypersensitivity without aspirin intolerance, and 50 controls in a Chinese population. The results showed that the frequencies of two SNPs (–344C>T, –66C>T) were similar to the normal controls. The allele frequency of –344CC was significantly higher in the patients with AICU compared to those with airway sensitivity (p = 0.019). We also studied both histamine release and CD203c expression on KU812 cells to assess aspirin-induced basophil activation. We found that the activity of basophil activation of AICU was significantly higher in the patients with AICU compared to those with airway hypersensitivity without aspirin intolerance. The mean fluorescence intensity of the CD203c expression were 122.5 ± 5.2 vs. 103.3 ± 3.3 respectively, (p T) is less likely to develop AICU and the basophil activation activity in the sera by measuring CD203c expression can be applicable to confirm the diagnosis of AICU.

    We systematically reviewed evidence to determine lactose intolerance (LI) prevalence, bone health after dairy-exclusion diets, tolerable dose of lactose in subjects with diagnosed LI, and management. We searched multiple electronic databases for original studies published in English from 1967-November 2009. We extracted patient and study characteristics using author's definitions of LI and lactose malabsorption. We compared outcomes in relation to diagnostic tests, including lactose challenge, intestinal biopsies of lactase enzyme levels, genetic tests, and symptoms. Fractures, bone mineral content (BMC) and bone mineral density (BMD) were compared in categories of lactose intake. Reported symptoms, lactose dose and formulation, timing of lactose ingestion, and co-ingested food were analyzed in association with tolerability of lactose. Symptoms were compared after administration of probiotics, enzyme replacements, lactose-reduced milk and increasing lactose load. Prevalence was reported in 54 primarily nonpopulation based studies (15 from the United States). Studies did not directly assess LI and subjects were highly selected. LI magnitude was very low in children and remained low into adulthood among individuals of Northern European descent. For African American, Hispanic, Asian, and American Indian populations LI rates may be 50 percent higher in late childhood and adulthood. Small doses of lactose were well tolerated in most populations. Low level evidence from 55 observational studies of 223,336 subjects indicated that low milk consumers may have increased fracture risk. Strength and significance varied depended on exposure definitions. Low level evidence from randomized controlled trials (RCTs) of children (seven RCTs) and adult women (two RCTs) with low lactose intake indicated that dairy interventions may improve BMC in select populations. Most individuals with LI can tolerate up to 12 grams of lactose, though symptoms became more prominent at doses above 12

    Coeliac disease is a permanent condition of gluten intolerance associated with characteristic gluten-sensitive changes in the jejunal mucosa. In Edinburgh and the Lothians Region of Scotland, the prevalence of the disease is one in 1637 (61/100,000) with considerable variation in age, and sex-specific prevalence and incidence. Several lines of evidence indicate an immunologic basis for the gluten-sensitive enteropathy in coeliac disease. Animal models of intestinal T cell-mediated reactions in the gut have shown pathologic features similar to those of coeliac disease. These include changes in villus and crypt architecture with crypt hyperplasia, and increased numbers of intraepithelial lymphocytes and of intraepithelial lymphocyte mitosis. Experimental CMI reactions also influence differentiation of goblet cells and expression of Ia antigen on epithelial cells, but these factors have not yet been reported for the coeliac mucosa. In addition to this circumstantial evidence, based on animal work, other factors which suggest that CMI reactions rather than antibodies are relevant to coeliac disease include the findings of antigliadin antibodies in a proportion of normal individuals, patients without gastrointestinal disease (seen in hospital), and patients with jejunal Crohn's disease. In addition, there is a well documented patient with adult onset primary hypogammaglobulinaemia and coeliac disease. The underlying pathogenesis in coeliac disease can be envisaged as failure of the normal inhibition of immune responses to this particular food antigen in the gut. Manipulation of immunoregulatory mechanisms would provide a new approach to treatment or cure of this disease and of other food protein-sensitive enteropathies.

    Full Text Available Adult bronchial asthma is characterized by chronic airway inflammation, and presents clinically with variable airway narrowing (wheezes and dyspnea and cough. Long-standing asthma induces airway remodeling, leading to intractable asthma. The number of patients with asthma has increased; however, the number of patients who die of asthma has decreased (1.2 per 100,000 patients in 2015. The goal of asthma treatment is to enable patients with asthma to attain normal pulmonary function and lead a normal life, without any symptoms. A good relationship between physicians and patients is indispensable for appropriate treatment. Long-term management by therapeutic agents and elimination of the causes and risk factors of asthma are fundamental to its treatment. Four steps in pharmacotherapy differentiate between mild and intensive treatments; each step includes an appropriate daily dose of an inhaled corticosteroid, varying from low to high levels. Long-acting β2-agonists, leukotriene receptor antagonists, sustained-release theophylline, and long-acting muscarinic antagonist are recommended as add-on drugs, while anti-immunoglobulin E antibody and oral steroids are considered for the most severe and persistent asthma related to allergic reactions. Bronchial thermoplasty has recently been developed for severe, persistent asthma, but its long-term efficacy is not known. Inhaled β2-agonists, aminophylline, corticosteroids, adrenaline, oxygen therapy, and other approaches are used as needed during acute exacerbations, by choosing treatment steps for asthma in accordance with the severity of exacerbations. Allergic rhinitis, eosinophilic chronic rhinosinusitis, eosinophilic otitis, chronic obstructive pulmonary disease, aspirin-induced asthma, and pregnancy are also important issues that need to be considered in asthma therapy.

    Chemical odor intolerance is a benign, non-specific, generally subjective syndrome triggered by inhalation of non-toxic doses of chemical compounds or products which had been previously well tolerated. We report five characteristic cases and discuss current data. Five patients (3 women, 2 men; age range 23-52 years) presented the basic criteria of chemical odor intolerance: acquired syndrome, non-specific signs (headache, nausea, vertigo ...) triggered by the odor of one or more chemical substances. Physical examination and exploratory tests were normal. In 3 cases, the course was favorable after evicting the causal substances. For the other 2 cases, intolerance spread to other compounds. Four of the patients changed their work situation because of the chemical odor intolerance. The diagnosis is clinical. Different pathogenic hypotheses have been put forward in the literature: immunological, toxic, neurobiological, psychological, and psychiatric mechanisms have been proposed. The mechanism is probably multifactorial but psychological factors appear to play an important role either as predisposing or triggering factors. Due to the social and occupational consequences of chemical odor intolerance, better knowledge of its prevalence and mechanism would be most helpful in managing these patients.

    Although conceived at the end of the 19th century as a synthetic analgesic agent with improved gastric tolerability vs. naturally occurring salicylates, acetylsalicylic acid (marketed as aspirin in 1899) turned out to be an ideal antiplatelet agent about 90 years later, following the understanding of its mechanism of action, the development of a mechanism-based biomarker for dose-finding studies, and the initiation of a series of appropriately sized, randomized clinical trials to test its efficacy and safety at low doses given once daily. At the turn of its 110th anniversary, aspirin continues to attract heated debates on a number of issues including (i) the optimal dose to maximize efficacy and minimize toxicity; (ii) the possibility that some patients may be 'resistant' to its antiplatelet effects; and (iii) the balance of benefits and risks in primary vs. secondary prevention.

    Meteorism, abdominal spasms, diarrhea, casually obstipation, flatulence and nausea are symptoms of fructose malabsorption (FIT) and/or lactose intolerance (LIT), but are also symptoms of irritable bowel syndrome (IBS). Therefore these diseases should be considered primarily in patients with digestive complaints. For diagnosis an H(2)-breath test is used.In 1,935 patients (526 m, 1,409 f) a fructose intolerance test and in 1,739 patients (518 m,1,221 f) a lactose intolerance test was done.FIT is found more frequently than LIT (57 versus 52 % in adults (p < 0,02) and in children 90 versus 62 % (p < 0,001)) and is in polyintolerances most frequently correlated to histamine intolerance (HIT). Headache (ca. 10 %), fatigue (ca. 5 %) and dizziness (ca. 3 %) may occur after the test, irrespective whether the test was positive or negative.In more than 2/3 of patients a diet reduced in fructose or lactose may lead to improvement or remission of these metabolic disorders. IBS, which is often correlated with FIT (183/221 patients = 83 %), can be improved by relevant but also not relevant diets indicating that irritable bowel disease seems to be caused primarily by psychological disorders.

    To review current literature of the benefits that aspirin provides for patients' cardiovascular health compared with the risk of AMD worsening. We performed a review and critically analyzed six cardiovascular and four ophthalmological trials regarding risks and benefits of aspirin use. The prospective randomized cardiovascular trials had a cumulative 167,580 while the 3 smaller ophthalmological data sets had a cumulative 12,015 subjects. The reviewed meta-analysis literature demonstrated a statistically significant 32% reduction in the risk of nonfatal stroke with regular aspirin users. The study also documented that aspirin users decreased the risk of fatal vascular deaths by 15%. Of the three ophthalmological studies highlighting the adverse affects of aspirin association with AMD, all suggested an exacerbation of AMD without statistical significance and broad confidence bands. Overall, the number, size, and quality of the cardiovascular studies recommending aspirin use are far superior to the fewer, smaller and conflicting studies suggesting a possible adverse effect of aspirin use in relation to AMD. The benefits of aspirin usage include preserving the duration and quality of life by decreasing stroke and heart attack risk. These benefits seem to far outweigh the theoretical risks of possibly exacerbating wet AMD, which can be reasonably controlled with anti-VEGF therapy.

    2015-12-01

    Muscle problems and other adverse symptoms associated with statin use are frequent reasons for non-adherence and discontinuation of statin therapy, which results in inadequate control of hyperlipidemia and increased cardiovascular risk. However, most patients who experience adverse symptoms during statin use are able to tolerate at least some degree of statin therapy. Given the profound cardiovascular benefits derived from statins, an adequate practical approach to statin intolerance is, therefore, of great clinical importance. Statin intolerance can be defined as the occurrence of myalgia or other adverse symptoms that are attributed to statin therapy and that lead to its discontinuation. In reality, these symptoms are actually unrelated to statin use in many patients, especially in those with atypical presentations following long periods of treatment. Thus, the first step in approaching patients with adverse symptoms during the course of statin therapy is identification of those patients for whom true statin intolerance is unlikely, since most of these patients would probably be capable of tolerating adequate statin therapy. In patients with statin intolerance, an altered dosing regimen of very low doses of statins should be attempted and, if tolerated, should gradually be increased to achieve the highest tolerable doses. In addition, other lipid-lowering drugs may be needed, either in combination with statins, or alone, if statins are not tolerated at all. Stringent control of other risk factors can aid in reducing cardiovascular risk if attaining lipid treatment goals proves difficult.

    Aspirin was first synthesised 100 years ago and its preparation and marketing is generally reckoned to have been the foundation of the pharmaceutical industry. For most of the time since then it has been used for the relief of pain and fever. The modern phase of aspirin use commenced with the reporting in 1974 of a randomised controlled trial in the secondary prevention of death by low-dose aspirin given to patients who had suffered a myocardial infarct. Reports of other trials followed and an overview of the first six trials was presented to the inaugural meeting of the Society for Clinical Trials in Philadelphia in 1980. There have been two further major overviews and the most recent, based on 145 trials, established that low-dose aspirin reduces vascular events by around one third. It has been estimated that, used appropriately, aspirin could prevent 100,000 premature deaths each year worldwide, at a cost of about 250 Pounds ($400) per life saved, and about 80 Pounds ($130) per cardiovascular event prevented. The evidence indicates that it is seriously underused at present. The aspirin story continues and trials are in progress to test other possible uses of aspirin, in vascular dementia, colorectal cancer, and cataract.

    2006-01-01

    Gluten sensitivity with or without coeliac disease (CD) symptoms and intestinal pathology has been suggested as a potentially treatable cause of various diseases. CD is a chronic disease which improves on withdrawal of wheat gliadins and barley, rye and oat prolamins from the diet. There have been numerous reports linking CD with several skin conditions. A body of evidence shows that dermatitis herpetiformis is actually a cutaneous manifestation of CD. Autoimmune diseases, allergic diseases, psoriasis and miscellaneous diseases have also been described with gluten intolerance. Dermatologists should be familiar with the appraisal of gluten sensitive enteropathy and should be able to search for an underlying gluten intolerance (GI). Serological screening by means of antigliadin, antiendomysial and transglutaminase antibodies should be performed. HLA typing is often useful in association with serologic tests. Intestinal biopsy is usually needed to establish the diagnosis of CD or GI. Thus, gluten intolerance gives rise to a variety of dermatological manifestations which may benefit from a gluten-free diet.

    Aims Aspirin is widely used as an anti-platelet agent for cardiovascular prophylaxis. Despite aspirin treatment, many patients experience recurrent thrombotic events, and aspirin resistance may contribute to this. We examined the prevalence of aspirin resistance in a healthy population, and investigated whether the platelet proteome differed in aspirin-resistant subjects. Methods Ninety-three healthy subjects received aspirin 300 mg daily for 28 days. Before and at the end of treatment, urine was taken to determine 11-dehydrothromboxane B2, and blood was taken to measure arachidonic acid (AA)-induced aggregation of platelet-rich plasma and to interrogate the platelet proteome by mass spectrometric analysis with further confirmation of findings using Western blotting. Results In two of the 93 subjects, neither AA-induced aggregation nor urinary 11-dehydrothromboxane B2 was effectively suppressed by aspirin, despite measurable plasma salicylate concentrations, suggesting the presence of true aspirin resistance. Despite no detectable differences in the platelet proteome at baseline, following aspirin a marked increase was seen in platelet glycoprotein IIIa expression in the aspirin-resistant but not aspirin-sensitive subjects. An increase in platelet glycoprotein IIIa expression with aspirin resistance was confirmed in a separate cohort of 17 patients with stable coronary artery disease on long term aspirin treatment, four of whom exhibited aspirin resistance. Conclusions In a healthy population, true aspirin resistance is uncommon but exists. Resistance is associated with an increase in platelet glycoprotein IIIa expression in response to aspirin. These data shed new light on the mechanism of aspirin resistance, and provide the potential to identify aspirin-resistant subjects using a novel biomarker. PMID:25099258

    The National Heart, Lung, and Blood Institute Severe Asthma Research Program (SARP) has characterized over the past 10 years 1,644 patients with asthma, including 583 individuals with severe asthma. SARP collaboration has led to a rapid recruitment of subjects and efficient sharing of samples among participating sites to conduct independent mechanistic investigations of severe asthma. Enrolled SARP subjects underwent detailed clinical, physiologic, genomic, and radiological evaluations. In addition, SARP investigators developed safe procedures for bronchoscopy in participants with asthma, including those with severe disease. SARP studies revealed that severe asthma is a heterogeneous disease with varying molecular, biochemical, and cellular inflammatory features and unique structure–function abnormalities. Priorities for future studies include recruitment of a larger number of subjects with severe asthma, including children, to allow further characterization of anatomic, physiologic, biochemical, and genetic factors related to severe disease in a longitudinal assessment to identify factors that modulate the natural history of severe asthma and provide mechanistic rationale for management strategies.

    The dramatic effectiveness of statins in improving the course of atherosclerotic cardiovascular disease tends to overshadow questions of statin intolerance. Thus after more than 25 years of clinical statin use, intolerance remains a poorly understood, frustrating issue for patients and providers. It has been extraordinarily difficult to define statin intolerance and its implications for clinical practice. Here, we briefly summarize current knowledge and raise questions that need to be addressed.

In this text we intend to show the existence of these forms of discrimination and intolerance, explain what they mean, its causes, and its aftermath. We analyze the specificity of each of the discrimination and intolerance in the artistic field,  and the social weight they have in the world today.

    Full Text Available Aspirin-exacerbated respiratory disease (AERD is one phenotype of asthma, often occurring in the form of a severe and sudden attack. Due to the time-consuming nature and difficulty of oral aspirin challenge (OAC for AERD diagnosis, non-invasive biomarkers have been sought. The aim of this study was to identify AERD-associated exonic SNPs and examine the diagnostic potential of a combination of these candidate SNPs to predict AERD. DNA from 165 AERD patients, 397 subjects with aspirin-tolerant asthma (ATA, and 398 normal controls were subjected to an Exome BeadChip assay containing 240K SNPs. 1,023 models (210-1 were generated from combinations of the top 10 SNPs, selected by the p-values in association with AERD. The area under the curve (AUC of the receiver operating characteristic (ROC curves was calculated for each model. SNP Function Portal and PolyPhen-2 were used to validate the functional significance of candidate SNPs. An exonic SNP, exm537513 in HLA-DPB1, showed the lowest p-value (p = 3.40×10-8 in its association with AERD risk. From the top 10 SNPs, a combination model of 7 SNPs (exm537513, exm83523, exm1884673, exm538564, exm2264237, exm396794, and exm791954 showed the best AUC of 0.75 (asymptotic p-value of 7.94×10-21, with 34% sensitivity and 93% specificity to discriminate AERD from ATA. Amino acid changes due to exm83523 in CHIA were predicted to be "probably damaging" to the structure and function of the protein, with a high score of '1'. A combination model of seven SNPs may provide a useful, non-invasive genetic marker combination for predicting AERD.

    2014-12-01

    Recent evidence has suggested a potential beneficial effect of aspirin on the risk of aneurysm rupture. This benefit must be weighed against its potential adverse effects as an antiplatelet agent in the setting of acute aneurysmal subarachnoid hemorrhage (SAH). A total of 747 consecutive patients with cerebral aneurysms were reviewed, comparing demographics, aneurysm features, presenting clinical and radiographic grades, vasospasm, and outcome at 1 year between patients with aneurysmal SAH taking aspirin on presentation and those who were not. The rate of hemorrhagic presentation was significantly greater in patients not taking aspirin (40% vs. 28%; P = 0.016). Among 274 patients presenting with aneurysmal SAH, there was no significant difference in presenting clinical (Hunt and Hess) and radiographic (Fisher) grade between patients taking aspirin and those who were not. There was also no significant difference in the rate of subsequent angiographic and delayed cerebral ischemia. Multivariate analysis of outcome at 1 year found only increasing age (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.04-1.12), Hunt and Hess grade (OR 3.01, 95% CI 1.81-5.03), and associated hypertension (OR 3.30, 95% CI 1.39-7.81) to be statistically significant risk factors for poor outcome (death or dependence), whereas aspirin use was not associated with poor outcome (OR 1.19, 95% CI 0.35-4.09; P = 0.78). In the present study, patients taking aspirin had a lower rate of hemorrhagic presentation. In addition, taking aspirin did not adversely impact presenting clinical grade or radiographic grade, vasospasm, and outcome in the setting of aneurysmal SAH. Copyright © 2014 Elsevier Inc.

    Science.gov (United States)

    Castilla-Guerra, L; Navas-Alcántara, M S; Fernández-Moreno, M C

    2014-04-01

    Some patients with a recent ischemic stroke who are being treated with aspirin as an antiaggregant suffer a new ischemic stroke. These patients (15-25%) have been called unresponsive to aspirin or aspirin resistant. The aspirin-resistant patients have a four-time greater risk of suffering a stroke. Furthermore, these strokes are generally more severe, with increased infarct volume and greater risk of recurrence. There is currently no ideal laboratory test to detect the resistance to the antiaggregant effect of aspirin. The study of resistance to aspirin would only be indicated in selected cases. In these patients, one should first rule out any "pseudo-resistance" to aspirin (lack of compliance, concomitant treatments that interfere with the action of the aspirin).

    Because nutritional intolerances generally are difficult to be diagnosed, Applied Kinesiology (AK) often is discussed as an alternative in this field. The uncertain scientific situation makes it necessary to assess the diagnostic value of AK. The method was compared with established laboratory tests such as RAST, lactose breath hydrogen test and a specific IgG test (Cytolisa). 315 children and adolescents, 0-17 years old, with different chronic diseases such as headache, abdominal pain, chronic eczema, hyperactivity, and bronchial asthma were studied by means of AK for 2 years. We found a moderate test-retest reliability (intraclass-kappa 0.62) but no inter-tester reliability (intraclass-kappa -0.01). Moreover, there was no statistically significant agreement with either RAST and Cytolisa (sensitivity 73.6%, specificity 45.2%) or lactose breath hydrogen test (sensitivity 77.1%, specificity 43.2%). In general, AK cannot be recommended for diagnosing nutritional intolerance. However, due to its high sensitivity, it could be a valuable tool to give some preliminary results. Copyright 2001 S.

    Several symptoms are common to different processes that affect the respiratory system and their precise assessment is key to a correct diagnosis. Amongst those symptoms, mostly dyspnoea oriented toward the possible diagnosis of asthma. Nevertheless, the concept of asthma has changed in recent times, as inflammation of the bronchial tree is valued as the pathogenic base of the process, although it can not be ignored that the bronchial hyperresponsiveness is still the basis of dyspnoea crisis. In the last years, several variants have been established, being defined as phenotypes and endotypes that can identify diverse asthmatic or pseudo-asthmatic processes, and there for it is questioned if asthma is not the only process, but a syndrome. In any case, it cannot be ignored that dyspnoea episodes can be based on bronchial hyperresponsiveness of genetic origin or due to inflammation because of unfavourable environmental conditions, as well as physical exercise or the ingestión of aspirin, processes in which other mechanisms are involved.

    Asthma phenotyping can facilitate understanding of disease pathogenesis and potential targeted therapies. To further characterize the distinguishing features of phenotypic groups in difficult-to-treat asthma. Children ages 6-11 years (n = 518) and adolescents and adults ages ≥12 years (n = 3612) with severe or difficult-to-treat asthma from The Epidemiology and Natural History of Asthma: Outcomes and Treatment Regimens (TENOR) study were evaluated in this post hoc cluster analysis. Analyzed variables included sex, race, atopy, age of asthma onset, smoking (adolescents and adults), passive smoke exposure (children), obesity, and aspirin sensitivity. Cluster analysis used the hierarchical clustering algorithm with the Ward minimum variance method. The results were compared among clusters by χ(2) analysis; variables with significant (P < .05) differences among clusters were considered as distinguishing feature candidates. Associations among clusters and asthma-related health outcomes were assessed in multivariable analyses by adjusting for socioeconomic status, environmental exposures, and intensity of therapy. Five clusters were identified in each age stratum. Sex, atopic status, and nonwhite race were distinguishing variables in both strata; passive smoke exposure was distinguishing in children and aspirin sensitivity in adolescents and adults. Clusters were not related to outcomes in children, but 2 adult and adolescent clusters distinguished by nonwhite race and aspirin sensitivity manifested poorer quality of life (P < .0001), and the aspirin-sensitive cluster experienced more frequent asthma exacerbations (P < .0001). Distinct phenotypes appear to exist in patients with severe or difficult-to-treat asthma, which is related to outcomes in adolescents and adults but not in children. The study of the therapeutic implications of these phenotypes is warranted. Copyright © 2013 American Academy of Allergy, Asthma & Immunology. Published by Mosby, Inc. All rights

    Full Text Available Antiplatelet therapy has been documented to reduce risks of cardiovascular disease after acute myocardial infarction, coronary artery bypass graft, and in chronic atrial fibrillation patients, amongst other risk factors. Conventional management of thrombosis-based disorders includes the use of heparin, oral anticoagulants, and the preferred antiplatelet agent aspirin. Interestingly, aspirin was not intended to be used as an antiplatelet agent; rather, after being repurposed, it has become one of the most widely prescribed antithrombotic drugs. To this end, there have been several milestones in the development of antiplatelet agents in the last few decades, such as adenosine diphosphate receptor inhibitors, phosphodiesterase inhibitors, and GPIIb/IIIa inhibitors. However, given some of the limitations of these therapies, aspirin continues to play a major role in the management of thrombotic and cardiovascular disorders and is expected to do so for years to come.

    Noninvasive ventilation (NIV) intolerance is one reason for NIV failure. However, the characteristics, predictors, and outcomes of NIV intolerance are unclear. A prospective observational study was performed in the respiratory intensive care unit of a teaching hospital. Subjects with acute respiratory failure who used NIV were enrolled. Initially, continuous use of NIV was encouraged. However, if the subject could not tolerate NIV, it was used intermittently. NIV intolerance was defined as termination of NIV due to subject refusal to receive it because of discomfort, even after intermittent use was attempted. A total of 961 subjects were enrolled in the study. Of these, 50 subjects (5.2%) experienced NIV intolerance after a median 2.4 h of NIV support. Age (OR = 0.98, 95% CI 0.963-0.996) and heart rate (OR = 1.02, 95% CI 1.006-1.030) measured before NIV were 2 independent risk factors of NIV intolerance. After 1-2 h of NIV, independent risk factors of NIV intolerance were heart rate (OR = 1.03, 95% CI 1.016-1.044) and breathing frequency (OR = 1.06, 95% CI 1.027-1.099). Intolerant subjects had no improvement in mean arterial pressure, heart rate, or breathing frequency after the NIV intervention. Moreover, intolerant subjects had a higher intubation rate (44.0% vs 25.8%, P = .008) and higher mortality (34.0% vs 22.4%, P = .08). The three most common complaints were that NIV worsened subjects' distress (46%), that NIV resulted in dyspnea (26%), and that the flow or pressure of NIV was too strong to bear (16%). NIV intolerance worsened subjects' outcomes. Younger subjects with a high heart rate and breathing frequency may be more likely to experience NIV intolerance.

The ionization potential and electron affinity of the NAA molecule as well as the charge densities were calculated. The electronic absorption spectra of Tc(V)-Asp and Tc(V)-ATS complexes have two characteristic absorption bands at 450 and 600 nm, but the Tc(V)-NAA spectrum has one characteristic band at 450 nm. As a comparative study, Mo-ATS complex was prepared and its electronic absorption spectrum is comparable with the Tc-ATS complex spectrum. (author).

  20. Space Flight Orthostatic Intolerance Protection

    2009-01-01

    This paper summarizes investigations conducted on different orthostatic intolerance protection garments. This paper emphasizes on the engineering and operational aspects of the project. The current Shuttle pneumatic Anti-G Suit or AGS at 25 mmHg (0.5 psi) and customized medical mechanical compressive garments (20-30 mmHg) were tested on human subjects. The test process is presented. The preliminary results conclude that mechanical compressive garments can ameliorate orthostatic hypotension in hypovolemic subjects. A mechanical compressive garment is light, small and works without external pressure gas source; however the current garment design does not provide an adjustment to compensate for the loss of mass and size in the lower torso during long term space missions. It is also difficult to don. Compression garments that do not include an abdominal component are less effective countermeasures than garments which do. An early investigation conducted by the Human Adaptation and Countermeasures Division at Johnson Space Center (JSC) has shown there is no significant difference between the protection function of the AGS (at 77 mmHg or 1.5 psi) and the Russian anti-g suit, Kentavr (at 25 mmHg or 0.5 psi). Although both garments successfully countered hypovolemia-induced orthostatic intolerance, the Kentavr provided protection by using lower levels of compression pressure. This more recent study with a lower AGS pressure shows that pressures at 20-30 mmHg is acceptable but protection function is not as effective as higher pressure. In addition, a questionnaire survey with flight crewmembers who used both AGS and Kentavr during different missions was also performed.

  1. TRUE RESISTANCE AND PSEUDORESISTANCE TO ASPIRIN

    2013-01-01

    Full Text Available Low dose aspirin reduces the secondary incidence of myocardial infarction and stroke. Drug resistance to aspirin might result in treatment failure. Despite this concern, no clear definition of aspirin resistance has emerged, and estimates of its incidence have varied remarkably. Researchers from university of Pennsylvania (Philadelphia, the USA, led by Dr. Tilo Grosser, aimed to determine the specific phenotype of true pharmacological resistance to aspirin — such as might be explained by genetic causes. However the study failed to identify a single case of true drug resistance. Pseudoresistance, reflecting delayed and reduced drug absorption, complicates enteric coated but not immediate release aspirin administration.

    Sensory intolerance refers to high levels of distress evoked by everyday sounds (e.g., sounds of people chewing) or commonplace tactile sensations (e.g., sticky or greasy substances). Sensory intolerance may be associated with obsessive-compulsive (OC) symptoms, OC-related phenomena, and other forms of psychopathology. Sensory intolerance is not included as a syndrome in current diagnostic systems, although preliminary research suggests that it might be a distinct syndrome. First, to investigate the latent structure of sensory intolerance in adults; that is, to investigate whether it is syndrome-like in nature, in which auditory and tactile sensory intolerance co-occur and are associated with impaired functioning. Second, to investigate the psychopathologic correlates of sensory intolerance. In particular, to investigate whether sensory intolerance is associated with OC-related phenomena, as suggested by previous research. A sample of 534 community-based participants were recruited via Amazon.com's Mechanical Turk program. Participants completed measures of sensory intolerance, OC-related phenomena, and general psychopathology. Latent class analysis revealed two classes of individuals: those who were intolerant of both auditory and tactile stimuli (n=150), and those who were relatively undisturbed by auditory or tactile stimuli (n=384). Sensory-intolerant individuals, compared to those who were comparatively sensory tolerant, had greater scores on indices of general psychopathology, more severe OC symptoms, a higher likelihood of meeting caseness criteria for OC disorder, elevated scores on measures of OC-related dysfunctional beliefs, a greater tendency to report OC-related phenomena (e.g., a greater frequency of tics), and more impairment on indices of social and occupational functioning. Sensory-intolerant individuals had significantly higher scores on OC symptoms even after controlling for general psychopathology. Consistent with recent research, these findings

    BACKGROUND: There is substantial variability in the perioperative administration of aspirin in patients undergoing noncardiac surgery, both among patients who are already on an aspirin regimen and among those who are not. METHODS: Using a 2-by-2 factorial trial design, we randomly assigned 10......,010 patients who were preparing to undergo noncardiac surgery and were at risk for vascular complications to receive aspirin or placebo and clonidine or placebo. The results of the aspirin trial are reported here. The patients were stratified according to whether they had not been taking aspirin before...... the study (initiation stratum, with 5628 patients) or they were already on an aspirin regimen (continuation stratum, with 4382 patients). Patients started taking aspirin (at a dose of 200 mg) or placebo just before surgery and continued it daily (at a dose of 100 mg) for 30 days in the initiation stratum...

    Statin therapy is the backbone of pharmacologic therapy for low-density lipoproteins cholesterol lowering and plays a pivotal role in cardiovascular disease prevention. Statin intolerance is understood as the inability to continue using a statin to reduce individual cardiovascular risk sufficiently, due to the development of symptoms or laboratory abnormalities attributable to the initiation or dose escalation of a statin. Muscle symptoms are the most common side effects observed. Areas covered: The main aim of this article is to present a review on published definitions of statin intolerance. In addition, a brief review on clinical aspects and risk factors of statin intolerance is provided and features for a common definition for statin intolerance are suggested. Expert opinion: A definition of statin intolerance by major drug regulatory agencies is not available. In clinical studies, different definitions are chosen and results are not comparable; different medical associations do not agree on one common definition. There is an unmet need to establish a common definition of statin intolerance to ensure an appropriate clinical use of this important drug class. Further work is required to develop a consensus definition on statin intolerance that could have significant positive impact on both research and clinical management.

    1996-01-01

    Full Text Available The prevalence and fatality rate of asthma have increased worldwide. Underdiagnosis and undertreatment of asthma are central to the occurrence of fatal asthma. Atopy is the principal risk factor associated with asthma. However, consideration of the epidemiologic, physiologic, pharmacologic, pathologic and clinical parameters of asthma assessment may provide valuable insight into death due to asthma. Psychologic and socioeconomic factors may further aggravate the asthma status. Ethnic minorities are at increased risk of asthma. The perception of dyspnea may be blunted in asthma sufferers. Slow-onset fatal asthma may be associated with submucosal eosinophilic, whereas sudden-onset may be associated with submucosal neutrophilia. Fatal asthma occurs in patients abusing regular |32-agonist therapy. Peak flow assessment often provides insight into asthma deterioration prior to signs of respiratory distress. Markers of risk of death due to asthma further identify the fatality-prone asthma patient.

    Aspirin allergy in a patient with acute coronary syndrome represents one of the more urgent challenges an allergist may face. Adverse reactions to aspirin are reported in 1.5% of patients with coronary artery disease. A history of adverse reaction to aspirin often leads to unnecessary withholding of this medication or use of alternative antiplatelet therapy which may be inferior or more costly. Aspirin therapy has been shown to reduce morbidity and mortality in patients with coronary artery disease. Rapid aspirin challenge/desensitization in the aspirin allergic patient has been consistently shown to be both safe and successful in patients with acute coronary syndromes.

    Aspirin is the prophylactic antiplatelet drug of choice for people with cardiovascular disease. Adding a second antiplatelet drug to aspirin may produce additional benefit for people at high risk and people with established cardiovascular disease. This is an update to a previously published review from 2011. To review the benefit and harm of adding clopidogrel to aspirin therapy for preventing cardiovascular events in people who have coronary disease, ischaemic cerebrovascular disease, peripheral arterial disease, or were at high risk of atherothrombotic disease, but did not have a coronary stent. We updated the searches of CENTRAL (2017, Issue 6), MEDLINE (Ovid, 1946 to 4 July 2017) and Embase (Ovid, 1947 to 3 July 2017) on 4 July 2017. We also searched ClinicalTrials.gov and the WHO ICTRP portal, and handsearched reference lists. We applied no language restrictions. We included all randomised controlled trials comparing over 30 days use of aspirin plus clopidogrel with aspirin plus placebo or aspirin alone in people with coronary disease, ischaemic cerebrovascular disease, peripheral arterial disease, or at high risk of atherothrombotic disease. We excluded studies including only people with coronary drug-eluting stent (DES) or non-DES, or both. We collected data on mortality from cardiovascular causes, all-cause mortality, fatal and non-fatal myocardial infarction, fatal and non-fatal ischaemic stroke, major and minor bleeding. The overall treatment effect was estimated by the pooled risk ratio (RR) with 95% confidence interval (CI), using a fixed-effect model (Mantel-Haenszel); we used a random-effects model in cases of moderate or severe heterogeneity (I 2 ≥ 30%). We assessed the quality of the evidence using the GRADE approach. We used GRADE profiler (GRADE Pro) to import data from Review Manager to create a 'Summary of findings' table. The search identified 13 studies in addition to the two studies in the previous version of our systematic review. Overall

    Full Text Available The diagnosis and treatment of lactose intolerance often does not resolve all the symptoms of postcibal bloating and flatulence. Included in this study were 104 lactose intolerant patients (71 female, 33 male who complained of residual postcibal discomfort in spite of adherence to and benefit from appropriate measures for their documented lactose intolerance (at least 20 ppm H2 after 25 g lactose as well as appropriate symptomatic discomfort. Clinical characteristics common to this group included: symptomatic diarrhea (12.5%, history of foreign travel (5.8%, endoscopic and pathological evidence of gastritis and helicobacter infection (19.2 and 8.7%, respectively, nonspecific abnormalities of small bowel follow-through (15.4%, Crohn’s disease (8.7% and colonic cliverticulosis (14.4%.

Intolerance to both fructose and sorbicol (administered as separate challenges, more than twice as common as intolerance to either one alone, occurred in 41.4% and was independent of sex. In conclusion, additional carbohydrate intolerances contribute to postcibal discomfort in more than 75% of lactose intolerant patients who remain symptomatic in spite of adherence to appropriate measures for this condition. While 62% of all patients had benefited significantly (greater than 50% from appropriate dietary measures and enzyme replacement for lactose intolerance, only 40% of those who were also fructose intolerant and 47% who were sorbitol intolerant benefited (greater than 50% from appropriate dietary measures (no enzyme replacement yet available for intolerance to these sugars.

  12. The role of aspirin in cancer prevention.

    Thun, Michael J; Jacobs, Eric J; Patrono, Carlo

    2012-04-03

    Clinical guidelines for prophylactic aspirin use currently only consider the cardiovascular benefits of aspirin, weighed against the potential harm from aspirin-induced bleeding. Daily aspirin use has been convincingly shown to reduce the risk of colorectal cancer and recurrence of adenomatous polyps, but in average-risk populations, these benefits alone do not outweigh harms from aspirin-induced bleeding. Recently published secondary analyses of cardiovascular trials provide the first randomized evidence that daily aspirin use may also reduce the incidence of all cancers combined, even at low doses (75-100 mg daily). This Review considers the general mechanism of action that defines aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) as a class, the specific advantages of aspirin over other NSAIDs for prophylactic use, the current evidence concerning the main health outcomes affected by aspirin use, and the hypothesis that inhibition of platelet activation may mediate both the cardioprotective and cancer-preventive effects of low-dose aspirin. It also considers how even a 10% reduction in overall cancer incidence beginning during the first 10 years of treatment could tip the balance of benefits and risks favourably in average-risk populations.

    Aspirin is often used to prevent thrombosis in pediatric cardiac surgery. The primary study aim was to assess aspirin resistance in this context. Secondary aims were to evaluate (1) the relationship between elevated inflammatory markers and thrombosis and (2) aspirin's effect on these levels. This was a prospective observational study of children undergoing cardiac surgery managed with and without aspirin. Aspirin response was assessed using the VerifyNow system and urinary 11-dehydrothromboxane B2 (uTxB2) measurements. Laboratory studies of inflammation were also obtained. 101 subjects were studied; 50 received aspirin. Six subjects (5.9%), 5 aspirin-treated, experienced symptomatic thrombosis. When measured by VerifyNow resistance was 43% after aspirin suppositories and 14% after additional days of oral aspirin. There was no correlation with thrombosis. Upper quartile post-operative day (POD) #5 uTxB2 was correlated with thrombosis in aspirin treated subjects (paspirin-treated subjects who experienced thrombosis had higher POD#5 uTxB2. This finding did not reach statistical significance (p=0.07). Elevated pre-operative C-reactive protein (CRP) was independently associated with thrombosis (paspirin. Aspirin inhibited ex-vivo platelet function with a low incidence of resistance. Elevated POD#5 uTxB2 and pre-operative CRP were correlated with thrombosis in aspirin treated subjects. Further studies are needed to determine whether children with high levels of uTxB2 despite aspirin therapy and/or those with elevated preoperative CRP are at increased risk for thrombosis.

    Aspirin (acetylsalicylic acid) is a nonsteroidal anti-inflammatory drug. Despite its wide uses for more than 100 years, knowledge about mechanism of action and therapeutic issues of aspirin are still under discussion. The use of aspirin has been changed from an analgesic, anti-pyretic and anti-inflammatory agent to an anti-thrombotic agent, especially in secondary prevention of cardiovascular events. Aspirin has reduced the risk of cardiovascular events by 25%. However, the phenomenon of "aspirin resistance" has been described that in 5%-60% of patients aspirin may not achieve adequate efficacy of suppressing platelet activity. The convinced causes of this phenomenon are still unknown. It is probably due to drugs interaction, inadequate dosage and so on. By far the existing studies of aspirin are insufficient to explain all phenomena of aspirin resistance. And the results are not always uniform about the same research. Therefore, the characteristics in different population with aspirin resistance may account for the complexity. It is unrealistic to elucidate all aspirin resistance by only one pathway. More studies are required to investigate the mechanisms in different population respectively. According to the theory of traditional Chinese medicine and the trait of cardiovascular disease, which often relapses and has a long history, aspirin resistance should be considered as collaterals disease. It can be treated with aspirin and traditional Chinese drugs which have the power to strengthen body resistance, reduce phlegm, remove blood stasis and toxic materials from meridians. The problem of aspirin resistance might be solved by this way, because the traditional Chinese medicine has the superiority of selecting appropriate therapeutic methods based on syndrome differentiation for different population and regulating the whole body's function. Subsequently, cardiovascular disease might be effectively prevented.

    Aspirin is effective in the prevention of cardiovascular events in high-risk patients. The primary established effect of aspirin on hemostasis is to impair platelet aggregation via inhibition of platelet thromboxane A2 synthesis, thus reducing thrombus formation on the surface of the damaged arterial wall. Growing evidence also indicates that aspirin exerts additional antithrombotic effects, which appear to some extent unrelated to platelet thromboxane A2 production. Aspirin can reduce thromb...

    Aspirin-exacerbated respiratory disease is a chronic and treatment-resistant disease, characterized by the presence of eosinophilic rhinosinusitis, nasal polyposis, bronchial asthma, and nonsteroidal anti-inflammatory drugs hypersensitivity. Alterations in arachidonic acid metabolism may induce an imbalance between pro-inflammatory and anti-inflammatory substances, expressed as an overproduction of cysteinyl leukotrienes and an underproduction of prostaglandin E2. Although eosinophils play a key role, recent studies have shown the importance of other cells and molecules in the development of the disease like mast cells, basophils, lymphocytes, platelets, neutrophils, macrophages, epithelial respiratory cells, IL-33 and thymic stromal lymphopoietin, making each of them promissory diagnostic and treatment targets. In this review, we summarize the most important clinical aspects of the disease, including the current topics about diagnosis and treatment, like provocation challenges and aspirin desensitization. We also discuss recent findings in the pathogenesis of the disease, as well as future trends in diagnosis and treatment, including monoclonal antibodies and a low salicylate diet as a treatment option.

    2015-01-01

    "Lactose intolerance (LI)" is considered a common problem in Asians, and in many parts of the world. Its prevalence and age of manifestation varies between by Asian country, for possible genetic or cultural reasons. Studies in Indonesian children 3-15 years old (y) are available within the past two decades, using a pure lactose tolerance test. The prevalences of lactose malabsorption (LM) in pre-elementary (3-5 y), elementary (6-11 y), and junior high (12-14 y) school-children were 21.3%, 57.8%, and 73%, respectively. An increasing trend for LM prevalence was seen within the pre-elementary group, from 9.1% at 3 y to 28.6% at 5 y. The most frequent symptoms of LI in junior high school (JHS) group were abdominal pain (64.1%), abdominal distention (22.6%), nausea (15.1%), flatulence (5.7%), and diarrhea (1.9%), mostly within one hour of lactose ingestion. In children with regular and irregular milk drinking, LM occurred in 81.2% and 69.6%; LI was found in 56.2% and 52.1%, respectively. Most JHS children with dairy-associated recurrent abdominal pain (RAP) symptoms proved to be malabsorbers. Dairy products most related to RAP were milk and yogurt. LI was found in 81% of RAP children with abdominal pain most frequently, followed by nausea, bloating, diarrhea, borborygmi, and flatulence. Symp-tom onset occurred 30 minutes after lactose ingestion, especially nausea, bloating, and abdominal pain. In RAP children LI symptoms mostly found in breath hydrogen concentration>20 ppm. More LI symptoms were found in lactose malabsorbers, but symptoms were mild and generally disappeared in 7 hours, and in most by 15 hours.

    2007-07-01

    At the beginning was the willow bark, which was considered as a medicine by Hippocrates, Dioscorides and Plinus. During the XVIIIth century, the Reverend Edward Stone re-discovered the willow for the cure of agues. In 1829, the french pharmacist Pierre Joseph Leroux isolated salicin. Raffaelle Piria was the first to synthesize salicylic acid from salicin (salicoside). Hermann Kolbe prepared salicylic acid from sodium phenate and carbon dioxide. And then acetylsalicylic acid was first prepared by Charles Gerhardt in 1853, but he did not succeed in identifying its structure. Felix Hoffmann, Arthur Eichengrun and Heinrich Dresen from Bayer Laboratories were at the origin of the use of Aspirin as a medicine. In 1971, John Vane showed that aspirin-like drugs inhibited prostaglandine synthesis.

    Clinical features of aspirin-exacerbated respiratory disease (AERD) consist of moderate to severe asthma associated with chronic rhinosinusitis (CRS), which are derived from overproduction of cysteinyl leukotrienes along with chronic type 2 mediated inflammation in the upper and lower airway mucosa. Area covered: This review provides recent up-to-date information regarding phenotypes of AERD and encompasses comprehensive diagnostic methods and treatment options. To confirm the diagnosis of AERD, provocation testing via nasal, inhalation or the oral route of aspirin remains the gold standard; in vitro diagnostic methods are still not available. Essential management is to avoid cross-reacting cyclooxygenase 1 (COX-1) inhibitors along with use of highly selective COX-2 inhibitors and to maintain pharmacologic treatment depending on the severity of asthma and chronic rhinosinusitis. Recent biologics, including anti-IgE and anti-IL5 antibodies, are required in severe AERD patients with CRS. Aspirin desensitization can be recommended when indicated. Expert commentary: AERD is a heterogeneous disease in terms of severity and associated allergic disease. When performing diagnosis and treatment for AERD, such disease characteristics need to be kept in mind.

    Buzás, György Miklós

    2015-09-20

    Lactose intolerance is the most prevalent intestinal malabsorption disorder. After presentation of its history, the author describes the emergence of lactose intolerance during the evolution of species, and the biochemistry of lactose as well as features of human and bacterial lactase enzymes are then described. The unequal distribution of lactose intolerance in different continents and population is discussed, followed by presentation of past and present prevalence data in Hungary. Adult-type hypolactasia is caused by a polymorphism of the MCM6 gene located upstream from the lactase gene on the long arm of the chromosome 2. It can be determined with the polymerase chain reaction. The intestinal symptoms of lactose intolerance are well known, but its extra-intestinal manifestations are less recognised. Invasive diagnostic methods (determination of lactase activity from small intestinal biopsies, lactose tolerance test), are accurate, but have been replaced by the non-invasive methods; their gold standard is the H2 breath test. Genetic testing is being used more and more frequently in Hungary too, and, presumably, the methane breath test will be also available in the near future. Lactose intolerance can be accompanied by inflammatory bowel diseases, coeliac disease and irritable bowel syndrome; it could be established whether this association is causal or not in order to start a correct diet and therapy.

    Anti-aspiryl antibodies were produced in rabbits and guinea pigs by inoculation of aspirin incorporated in complete or incomplete Freund's adjuvant. These antibodies were readily detected by passive haemagglutination using rabbit erythrocytes incubated with aspirin at alkaline pH. Aspiryl conjugates with ovalbumin, human gamma-globulin, bovine gamma-globulin and rabbit serum were also prepared by incubating the proteins with aspirin at alkaline pH. Aspiryl conjugates prepared by this technique behaved, immunologically, identically with the conjugates prepared from aspirin chloride. By contrast, the molar absorbance at 305 nm of the conjugates prepared from aspirin was about 25 times lower than the molar absorbance of the conjugates prepared from aspirin chloride. Since the absorbance of salicylic acid is about eight times greater than that of aspirin, the conclusion is drawn that the aspiryl/salicylyl ratio is significantly higher in the conjugates prepared by incubating proteins with aspirin at alkaline pH than in the conjugates prepared from aspirin chloride. In parallel experiments, salicylic acid did not induce formation of specific antibodies capable of reacting with aspirin- or salicylic acid-treated red cells. Sera giving positive passive haemagglutination with aspirin-treated erythrocytes did not react with erythrocytes treated with salicylic acid or acetic anhydride.

    Increasing evidence supports a role for aspirin use in reducing the incidence and mortality of several cancer types. This has spurred a new wave of interest in this widely used drug. In this review, we present and evaluate the epidemiologic evidence of the association between the use of aspirin....... Overall, observational studies indicate modest reductions in risk of ovarian and endometrial cancer with aspirin use, whereas the results for non-aspirin NSAID use are equivocal. The strongest inverse associations have been reported for long-term consistent aspirin use, notably among subgroups of users (e.......g., those with high body mass index). Few studies have evaluated the influence of NSAID use on the mortality of ovarian or endometrial cancer, and substantial heterogeneity of study characteristics and results preclude any conclusions. Additional studies of aspirin and non-aspirin NSAID use and ovarian...

  18. The Role of Allergy in Severe Asthma

    Summary The classification of asthma to identify forms which have different contributing causes is useful for all cases in which the disease requires regular treatment, but it is essential for the management of severe asthma. Many forms of the disease can occur, and complex mixtures are not uncommon; here we artificially separated the cases into four groups: i) inhalant allergy, ii) fungal sensitization with or without colonization (including ABPA); iii) severe sinusitis with or without aspirin-exacerbated respiratory disease (AERD), and iv) non-inflammatory cases, including those associated with severe obesity and vocal cord dysfunction (VCD). The reason for focusing on these groups is because they illustrate how much the specific management depends upon correct classification. Inhalant allergy can present as chronically severe asthma. However, severe attacks of asthma requiring hospital admission can occur in cases which are generally only mild or moderate. The best recognized and probably the most common cause of these acute episodes is acute infection with a rhinovirus. Recent evidence suggests that high titer IgE, particularly to dust mite, correlates to exacerbations of asthma related to rhinovirus infection. While it is well recognized that the fungus Aspergillus can colonize the lungs and cause severe disease, it is less well recognized that those cases may not have full criteria for diagnosis of ABPA or may involve other fungi. Identifying fungal cases is important, because treatment with imidazole antifungals can provide significant benefit. Taken together, specific treatment using allergen avoidance, immunotherapy, anti-IgE, or antifungal treatment is an important part of the successful management of severe asthma, and each of these requires correctly identifying specific sensitization.

    The American Academy of Pediatrics Committee on Nutrition presents an updated review of lactose intolerance in infants, children, and adolescents. Differences between primary, secondary, congenital, and developmental lactase deficiency that may result in lactose intolerance are discussed. Children with suspected lactose intolerance can be assessed clinically by dietary lactose elimination or by tests including noninvasive hydrogen breath testing or invasive intestinal biopsy determination of lactase (and other disaccharidase) concentrations. Treatment consists of use of lactase-treated dairy products or oral lactase supplementation, limitation of lactose-containing foods, or dairy elimination. The American Academy of Pediatrics supports use of dairy foods as an important source of calcium for bone mineral health and of other nutrients that facilitate growth in children and adolescents. If dairy products are eliminated, other dietary sources of calcium or calcium supplements need to be provided.

    Chronic rhinosinusitis (CRS) with nasal polyposis (NP) may be associated with hypersensitivity to nonsteroidal anti-inflammatory drugs, representing a syndrome of aspirin-exacerbated respiratory disease (AERD). The aim of the study was to validate a simple measurement of urinary leukotriene E4 (uLTE4) excretion for the diagnosis of AERD in patients with CRS and indication for surgery. Subjects requiring functional endoscopic sinus surgery (FESS) were recruited from the Department of Otolaryngology (n = 24). Before surgery, a standard oral placebo-controlled aspirin challenge was performed to diagnose aspirin hypersensitivity. Urine samples were collected on the placebo day and both before and within 2 to 4 hours after aspirin challenge for uLTE4 measurement. All patients with CRS had sinusitis confirmed by computed tomography. Previous ear, nose, and throat surgery was performed in 70% of the patients, NP was present in 86%, and asthma was diagnosed in 62.5%. AERD was diagnosed in 8 subjects (7 women and 1 man). Five of those patients had bronchoconstriction. At baseline, median uLTE4 was 7.5-times higher in AERD subjects than in the remaining patients. It increased almost 6-fold following the challenge, while remained unchanged in patients without aspirin hypersensitivity. Pretest uLTE4 had a sensitivity of 87.5% and specificity of 93.75% to diagnose aspirin hypersensitivity in patients with CRS. After the challenge, the values improved to 100% sensitivity and 93% specificity. Among CRS subjects requiring FESS, as many as 33.3% may have AERD and respond to a small provocative dose of aspirin with bronchoconstriction and/or mucosal and skin edema. A simple and inexpensive measurement of uLTE4 can help diagnose AERD in patients with CRS with sensitivity of 87.5%, but its specificity is limited and depends on the arbitrary threshold of uLTE4.

    The concept of "pharmacogenetics" addresses genetically determined variation in how individuals respond to drugs. Accordingly, specific genetic variants have been suggested as contributors to a reduced response to various antiplatelet drugs. Aspirin is a cornerstone in secondary cardiovascular prevention and has been thoroughly investigated. The efficacy of aspirin is well documented, although with considerable interindividual variation. According to meta-analyses, a reduced antiplatelet effect of aspirin confers an increased risk of cardiovascular events. The platelet response to aspirin is assessed by in vitro evaluation of thromboxane-dependent platelet function. A reduced antiplatelet effect of aspirin can be explained by several mechanisms, which are largely determined by clinical, pharmacodynamic, biological and genetic factors. During the past decade, numerous studies have identified genetic polymorphisms significantly associated with cardiovascular events and modulating the antiplatelet effect of aspirin. However, results have been contradictory allowing only few firm conclusions to be drawn. Polymorphisms in genes encoding glycoproteins (IIb/IIIa, Ia/IIa, VI and Ibα), cyclooxygenases (1 and 2), adenosine diphosphate receptors (P2Y1 and P2Y12) and proteins of importance for haemostasis (thromboxane A2 receptor, coagulation factor XIII, etc.) have been investigated. In particular, a polymorphism in the gene encoding glycoprotein IIb/IIIa has been associated with a reduced antiplatelet effect of aspirin. The additive value of an individual's genetic makeup in predicting the antiplatelet effect of aspirin and the risk of cardiovascular events remains controversial. The present review outlines the pharmacology of aspirin and provides an overview of specific genetic variations considered to influence the antiplatelet effect of aspirin.

    The effect of aspirin on nasal resistance to airflow was investigated by rhinomanometry in 25 healthy subjects before and after ingestion of aspirin or vitamin C in a double blind crossover trial. Aspirin caused a significant increase in nasal resistance compared with vitamin C. The effect of aspirin may be due to its inhibition of the synthesis of prostaglandins.

    The author summarises the interrelations between lactose intolerance, calcium and vitamin D metabolism and osteoporosis. Lactose intolerance enhances the risk of forearm and hip fractures in some patients. Lactase gene genotype and fracture risk are related in some populations. Calcium and vitamin D supplementation increase bone mineral content and they are justified in children, during pregnancy and lactation, and in postmenopausal women. The intake of milk and milk products could increase the risk of ovarian carcinoma. CC genotype of the lactase gene increased the risk of colorectal carcinoma in Finns; no such effect was observed in British, Spanish and Italian patients. Even small quantities of lactose in drugs (10-750 mg) could elicit intolerance symptoms due to individual susceptibility. In spite of public knowledge and advertising, controlled studies did not prove the beneficial effect of either a lactose-free diet, enzyme supplementation or probiotics in an evidence-based manner. While accepted guidelines are lacking, a personalised therapy is mandatory. In spite of increasing public interest in lactose intolerance, many unknown factors must still be studied.

    True lactose intolerance (symptoms stemming from lactose malabsorption) is less common than is widely perceived, and should be viewed as just one potential cause of cows' milk intolerance. There is increasing evidence that A1 beta-casein, a protein produced by a major proportion of European-origin cattle but not purebred Asian or African cattle, is also associated with cows' milk intolerance. In humans, digestion of bovine A1 beta-casein, but not the alternative A2 beta-casein, releases beta-casomorphin-7, which activates μ-opioid receptors expressed throughout the gastrointestinal tract and body. Studies in rodents show that milk containing A1 beta-casein significantly increases gastrointestinal transit time, production of dipeptidyl peptidase-4 and the inflammatory marker myeloperoxidase compared with milk containing A2 beta-casein. Co-administration of the opioid receptor antagonist naloxone blocks the myeloperoxidase and gastrointestinal motility effects, indicating opioid signaling pathway involvement. In humans, a double-blind, randomized cross-over study showed that participants consuming A1 beta-casein type cows' milk experienced statistically significantly higher Bristol stool values compared with those receiving A2 beta-casein milk. Additionally, a statistically significant positive association between abdominal pain and stool consistency was observed when participants consumed the A1 but not the A2 diet. Further studies of the role of A1 beta-casein in milk intolerance are needed.

    Full Text Available Abstract Adverse reactions to food intake have very diverse etiology and symptomatology. Regarding milk, its food allergy is presented as lactose intolerance, the sugar in milk, or allergy to milk protein. Despite having different symptomatology, confusions among allergic conditions to dairy and its mediators are common. Milk protein allergy originates from protein components present in milk, causing reactions to either the protein fractions in emulsion (caseins or in whey (milk albumin. The allergic reaction is type IV mediated by T lymphocytes. The allergic reaction produces severe cellular damage and it triggers physical, mental and emotional symptomatology that may vary in time, intensity and severity. Lactose intolerance is originated by total or partial absence of the enzyme that digests this disaccharide. Lactose intolerance can be primary or congenital and secondary; the former being more rare and severe, the latter being more common. Lactase deficiency can be diagnosed by symptoms associated with cramping and diarrhea. Thus, the objective of this study was to conduct a review of available literature on cow’s milk protein allergy and lactose intolerance.

    Metformin is the most widely prescribed drug for patients with type 2 diabetes mellitus and the first-line pharmacological option as supported by multiple international guidelines, yet a rather large proportion of patients cannot tolerate metformin in adequate amounts because of its associated gastrointestinal (GI) adverse events (AEs). GI AEs typically encountered with metformin therapy include diarrhoea, nausea, flatulence, indigestion, vomiting and abdominal discomfort, with diarrhoea and nausea being the most common. Although starting at a low dose and titrating slowly may help prevent some GI AEs associated with metformin, some patients are unable to tolerate metformin at all and it may also be difficult to convince patients to start metformin again after a bout of GI AEs. Despite this clinical importance, the underlying mechanisms of the GI intolerance associated with metformin are poorly known. In the present review, we discuss: the epidemiology of metformin-associated GI intolerance and its underlying mechanisms; genotype variability and associated factors affecting metformin GI intolerance, such as comorbidities, co-medications and bariatric surgery; clinical consequences and therapeutic strategies to overcome metformin GI intolerance. These strategies include appropriate titration of immediate-release metformin, use of extended-release metformin, the promise of delayed-release metformin and gut microbiome modulators, as well as alternative pharmacological therapies when metformin cannot be tolerated at all. Given the available data, all efforts should be made to maintain metformin before considering a shift to another drug therapy. © 2016 John Wiley & Sons Ltd.

  1. Type 2 Cysteinyl Leukotriene Receptors Drive IL-33-Dependent Type 2 Immunopathology and Aspirin Sensitivity.

    Cysteinyl leukotrienes (cysLTs) facilitate mucosal type 2 immunopathology by incompletely understood mechanisms. Aspirin-exacerbated respiratory disease, a severe asthma subtype, is characterized by exaggerated eosinophilic respiratory inflammation and reactions to aspirin, each involving the marked overproduction of cysLTs. Here we demonstrate that the type 2 cysLT receptor (CysLT2R), which is not targeted by available drugs, is required in two different models to amplify eosinophilic airway inflammation via induced expression of IL-33 by lung epithelial cells. Endogenously generated cysLTs induced eosinophilia and expanded group 2 innate lymphoid cells (ILC2s) in aspirin-exacerbated respiratory disease-like Ptges-/- mice. These responses were mitigated by deletions of either Cysltr2 or leukotriene C4 synthase (Ltc4s). Administrations of either LTC4 (the parent cysLT) or the selective CysLT2R agonist N-methyl LTC4 to allergen sensitized wild-type mice markedly boosted ILC2 expansion and IL-5/IL-13 generation in a CysLT2R-dependent manner. Expansion of ILC2s and IL-5/IL-13 generation reflected CysLT2R-dependent production of IL-33 by alveolar type 2 cells, which engaged in a bilateral feed-forward loop with ILC2s. Deletion of Cysltr1 blunted LTC4-induced ILC2 expansion and eosinophilia but did not alter IL-33 induction. Pharmacological blockade of CysLT2R prior to inhalation challenge of Ptges-/- mice with aspirin blocked IL-33-dependent mast cell activation, mediator release, and changes in lung function. Thus, CysLT2R signaling, IL-33-dependent ILC2 expansion, and IL-33-driven mast cell activation are necessary for induction of type 2 immunopathology and aspirin sensitivity. CysLT2R-targeted drugs may interrupt these processes. Copyright © 2018 by The American Association of Immunologists, Inc.

    Asthma is a common, chronic, non-communicable respiratory disease that affects millions of children worldwide. Asthma exacerbations can range from mild to severe and can have an unfavorable impact on the quality of life of children and their caregivers. Asthma exacerbations often result in absenteeism from school or work, activity intolerance and emergency hospital visits. One strategy to address this health issue in an attempt to improve health outcomes is school-based asthma educational programs. A review of the literature revealed that previous systematic reviews have examined similar topics on the effectiveness of school-based asthma educational programs that have included collaborative efforts between parents and schools. No systematic reviews were found that examined the effectiveness of school-based asthma educational programs that exclusively included children and their caregivers. Research has not been systematically reviewed to determine the effectiveness of a school-based asthma educational program within a familial context. To identify the best available evidence on the effectiveness of school-based family asthma educational programs that exclusively included both children and caregivers on the quality of life and number of asthma exacerbations of children aged five to 18 years with a clinical diagnosis of asthma.

    Aspirin-exacerbated respiratory disease (AERD) is characterized by chronic eosinophilic nasal polyps, asthma, and airway reactions upon cyclooxygenase (COX) 1 inhibition. AERD is present in up to 7% of adult patients with asthma and the underlying pathogenesis remains largely elusive but prostaglandin D2, cysteinyl leukotrienes, mast cells, and type 2 cytokines are thought to contribute. A wealth of studies have recently implicated group 2 innate lymphoid cells (ILC2), a novel lineage-negative lymphocyte population that produces type 2 cytokines, in human allergic disease pathogenesis. Importantly, our recent work identified that ILC2s are recruited to the nasal mucosa of patients on AERD after COX-1 inhibitor administration. Here, we review the potential impact of ILC2s in the development and propagation of type 2 inflammation in AERD.

    Impaired tolerance to distress may help explain part of the cognitive and functional impairments in schizophrenia. This project investigated distress intolerance in schizophrenia patients (SZ) as compared to controls, and whether distress intolerance represented an independent domain in relationship to symptoms, cognition, and functional capacity. Healthy controls (n=43) and SZ (n=65) completed a psychological distress challenge experiment and their levels of intolerance to distress were estimated. SZ showed increased distress intolerance such that they were significantly more likely to terminate the distress challenge session early compared to controls. Greater distress intolerance was associated with reduced functional capacity and worse cognitive performance in SZ. Mediation analyses suggested that distress intolerance had an independent effect on functional capacity, while some of this effect was mediated by cognitive performance. Our results suggest that distress intolerance is a promising domain for treatment research, and functional capacity may be improved by targeting treatments towards SZ patient’s ability to tolerate distress.

    This paper scrutinizes the impact of intolerance toward diverse ethnic, religious, and cultural groups on an individual's willingness to actively engage in non-violent protest. Following new insights, we examine the individual as well as the ecological effect of social intolerance on protest...... behavior. Drawing from insights of social psychology and communication science, we expect that the prevalence of intolerance reinforces the positive effect of individual-level intolerance on protest participation. From a rational choice perspective, however, a negative moderating effect is expected......, as the expression of opinions becomes redundant for intolerant individuals in an intolerant society. We base our multilevel analyses on data from the World Values Surveys covering 32 established democracies. Our results reveal that intolerance leads to more non-violent protest participation.

    Aspirin is the mainstay of anti-platelet therapy in the secondary prevention of cardiovascular disease. However, problems with aspirin safety and resistance demand clinical strategies based on multiple pharmacological approaches. Prodrugs of aspirin may offer beneficial effects in terms of gastro-intestinal safety and multiple pharmacological approaches. However, the pharmacological profile of aspirin prodrugs in human platelets has not been completed yet. We aimed to compare the effects of aspirin and prodrugs of aspirin (1-5) on human platelet aggregation stimulated by ADP and collagen and associated receptor expression (GPIIb/IIIa and P-selectin) in platelet-rich plasma (PRP) and washed platelets (WP). As aspirin is released from prodrugs following esterase hydrolysis we studied the expression and activity of butyrylcholineterase (BuChE) and carboxyesterase (CE) in plasma and platelets. The mechanism of prodrug-induced platelet aggregation inhibition was explored by studying the effects of plasma and purified human BuChE on aggregation. Finally, the relative contribution of nitric oxide (NO) bioactivity to nitrate-containing prodrugs of aspirin-induced inhibition of aggregation was determined using 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ,) a selective inhibitor of the soluble guanylyl cyclase. ST0702, 2, a nicotinic acid-aspirin codrug was equipotent with aspirin with respect to inhibition of collagen-induced platelet aggregation. Compound 4, a NO releasing aspirin was the most potent inhibitor of ADP-induced platelet aggregation, an effect partially reversed by ODQ. The platelet inhibitory effects of aspirin prodrugs were time-dependent as the maximal inhibitory effects against collagen-induced aggregation were achieved by aspirin at 2 min, 1 at 5 min and ST0702 at 15 min. The aspirin prodrugs were significantly less potent in WP than in PRP and the reverse was true of aspirin. In the presence of complete BuChE inhibition in PRP, there was almost

    Aspirin (acetylsalicylic acid) has been used ever since the Antiquity for its painkilling and anti-inflammatory effects. Its antiplatelet properties have then extended its indications to the field of coronaropathy and vascular cerebral disease, and finally to vascular placental disease. Aspirin has been widely prescribed since the 1980's to prevent pre-eclampsia, intra-uterine growth retardation and fetal death of vascular origin. It has also been proposed to prevent unexplained recurrent miscarriages. Its use during pregnancy is considered as safe, provided the daily doses do not exceed 100mg. Aspirin has been proven efficient to prevent pre-eclampsia and fetal growth restriction in high-risk patients. The benefits of prescribing aspirin have been demonstrated neither for vascular placental disease prevention in low risk patients, nor in cases of unexplained recurrent miscarriages.

    Aspirin and other non-steroidal anti-inflammatory drugs reduce the risk of cancer due to their anti-proliferative and apoptotic effects, which are the important mechanisms for their anti-tumor activity. Here, the effect of aspirin on human cholangiocarcinoma cells (KKU-214) and the underlying mechanisms of its action were explored. Cell proliferation was measured by sulforhodamine B (SRB) assay, while cell cycle distribution and apoptosis were determined by flow cytometry. Western blotting was used to explore protein expression underlying molecular mechanisms of anti-cancer treatment of aspirin. Aspirin reduced cell proliferation in a dose- and time-dependent manner, and altered the cell cycle phase distribution of KKU-214 cells by increasing the proportion of cells in the G0/G1 phase and reducing the proportion in the S and G2/M phases. Consistent with its effect on the cell cycle, aspirin also reduced the expression of cyclin D1 and cyclin‑dependent kinase 4 (Cdk-4), which are important for G0/G1 cell cycle progression. Treatment with aspirin led to increased induction of apoptosis in a dose-dependent manner. Further analysis of the mechanism underlying the effect of this drug showed that aspirin induced the expression of the tumor-suppressor protein p53 while inhibiting the anti-apoptotic protein B‑cell lymphoma-2 (Bcl-2). Correspondingly, the activation of caspase-9 and -3 was also increased. These findings suggest that aspirin causes cell cycle arrest and apoptosis, both of which could contribute to its anti-proliferative effect. Creative Commons Attribution License

  14. Asthma and obesity.

    The prevalence and incidence of asthma have increased among obese children and adults, particularly among women. Obesity seems to be a predisposing factor for the development of asthma, but the underlying mechanisms of its influence are still uncertain. Various hypotheses have been proposed to explain the link between obesity and asthma such as a common genetic predisposition, developmental changes, altered lung mechanics, the presence of a systemic inflammatory process, and an increased prevalence of associated comorbid conditions. Over-diagnosis of asthma does not seem to be more frequent in obese compared to non-obese subjects, but the added effects of obesity on respiratory symptoms can affect asthma control assessment. Obesity can make asthma more difficult to control and is associated with a reduced beneficial effect of asthma medications. This could be due to a change in asthma phenotype, particularly evidenced as a less eosinophilic type of airway inflammation combined to the added effects of changes in lung mechanics. Weight loss is associated with a universal improvement of asthma and should be part of asthma management in the obese patient. Additional research should be conducted to better determine how obesity influences the development and clinical expression of asthma, establish the optimal management of asthma in this population and determine how obesity affects long-term asthma outcomes in these patients. © 2012 Blackwell Publishing Ltd.

    It is well recognized that atopic sensitization is an important risk factor for asthma, both in adults and in children. However, the role of allergy in severe asthma is still under debate. The term 'Severe Asthma' encompasses a highly heterogeneous group of patients who require treatment on steps 4-5 of GINA guidelines to prevent their asthma from becoming 'uncontrolled', or whose disease remains 'uncontrolled' despite this therapy. Epidemiological studies on emergency room visits and hospital admissions for asthma suggest the important role of allergy in asthma exacerbations. In addition, allergic asthma in childhood is often associated with severe asthma in adulthood. A strong association exists between asthma exacerbations and respiratory viral infections, and interaction between viruses and allergy further increases the risk of asthma exacerbations. Furthermore, fungal allergy has been shown to play an important role in severe asthma. Other contributing factors include smoking, pollution and work-related exposures. The 'Allergy and Asthma Severity' EAACI Task Force examined the current evidence and produced this position document on the role of allergy in severe asthma. © 2016 John Wiley & Sons A/S.

    • BACKGROUND: Dairy products intolerance is defined by existing of gastrointestinal symptoms following dairy product consumption. Its prevalence varies among different countries. This study is conducted to determine the frequencies and severities of intolerance symptoms in the consumption of different dairy products in Iranian students of Medical Sciences.
    • METHODS: In this cross-sectional study, 1041 students from Isfahan University of Medical Sciences who apparently were healthy and had not used any drug before, participated.
    • The questionnaire included information about dairy product consumption and avoidance, severity of dairy intolerance symptoms included gas passing, flatulence, diarrhea and abdominal pain and coexistence of irritable bowel syndrome (IBS.
    • RESULTS: The frequencies of dairy intolerance syndromes in milk, yoghurt, cheese and ice cream consumption were 51.1% (532, 16.6% (173, 11.7% (122 and 13.4% (140, respectively. Most severe symptoms for milk, yoghurt, cheese and ice cream intolerance were diarrhea (2.11 ± 0.08, gas passing (1.56 ± 0.09 and flatulence (1.49 ± 0.09, respectively. Fifty (9.4% of symptomatic respondents never drank milk. Correlation coefficient between symptoms severity and the avoidance of consumption in milk intolerance was 0.38.
    • CONCLUSIONS: Students tolerate other dairy products better in comparison with milk. In the present study, the phenomenon as irritable bowel syndrome was not strongly associated with the severity of all symptoms in dairy intolerant persons. Also, there were weak association between the severity of symptoms with dairy consumption and avoidance, but

      Intolerance of uncertainty (IU) is a transdiagnostic construct associated with several anxiety and related disorders. Three studies were conducted to explore the potential relationship between IU and body dysmorphic disorder (BDD). Study 1 revealed a positive relationship between IU and BDD symptoms above symptoms of anxiety and depression in an unselected student sample (N=88). Study 2 demonstrated a similar relationship between IU and BDD symptoms above negative affectivity and intolerance of ambiguity in a community sample (N=116). Study 3 found that a clinical BDD sample (N=23) reported greater IU than healthy controls (N=20), though this relationship was accounted for by symptoms of anxiety and depression. Greater IU predicted functional impairment in the clinical sample above BDD symptoms and past-week anxiety and depression. The observed relationship between IU and BDD symptoms provides preliminary support for the relevance of IU to this population. Copyright © 2015 Elsevier Ltd. All rights reserved.

  1. Religious Intolerance in the Cortes of Cadiz

    Directory of Open Access Journals (Sweden)

    Juan Pablo Domínguez

    2017-05-01

    Full Text Available In recent years there has been no shortage of studies on religious intolerance in the Cadiz Cortes, but many of them are burdened by two critical errors. The first one is to focus the arguments on article 12 of the Constitution, without paying attention to other parliamentary debates in which the intolerant policy of the Cortes was more clearly expounded. The second common mistake is to ignore the circumstances which prevented some deputies from freely speaking their minds on religious matters. Through a detailed analysis of the proceedings of the Cortes, as well as other sources of the period, this article is intended to remedy both shortcomings, and thus to question certain common assumptions in current historiography. This approach leads to the conclusion that, while some deputies may had hidden his penchant for freedom of conscience, the decrees and speeches of the Cortes were more intolerant than many suppose. Not only they ordered to punish all dissenters from the Church's doctrines, but they decreed death penalty for anyone who dared to suggest the introduction of religious freedom in Spain.

  2. Lactase Non-persistence and Lactose Intolerance.

    2017-05-01

    To evaluate the clinical and nutritional significance of genetically determined lactase non-persistence and potential lactose and milk intolerance in 65-70% of the world's adult population. Milk consumption is decreasing in the USA and is the lowest in countries with a high prevalence of lactase non-persistence. The dairy industry and Minnesota investigators have made efforts to minimize the influence of lactose intolerance on milk consumption. Some lactose intolerant individuals, without co-existent irritable bowel syndrome, are able to consume a glass of milk with a meal with no or minor symptoms. The high frequency of lactase persistence in offspring of Northern European countries and in some nomadic African tribes is due to mutations in the promoter of the lactase gene in association with survival advantage of milk drinking. Educational and commercial efforts to improve calcium and Vitamin D intake have focused on urging consumption of tolerable amounts of milk with a meal, use of lowered lactose-content foods including hard cheeses, yogurt, and lactose-hydrolyzed milk products.

  3. Statin intolerance: Now a solved problem

    Full Text Available Statins are the most effective and widely used drugs for treating dyslipidemia, a major risk factor for coronary heart disease. These are one of the safest hypolipidemic drugs but many patients are bound to discontinue statins due to their side effects. Hepatotoxicity, myotoxicity and peripheral neuropathy are important out of them. Discontinuation of statins leads to dylipidemia and its grave consequences. Hence, there should be enough strategies for statin intolerant patients, so that they can be saved from these consequences. These side effects can be avoided by the awareness of certain factors viz. potential drug interactions and dose adjustment according to patho-physiology of the patient. Baseline investigations for liver function and muscle toxicity should be done before initiating statin therapy. Here, we are discussing various options for statin intolerant hyperlipidemic patients such as lower and intermittent dosing of statins, alternate hypolipidemic drugs, red yeast rice, supplementation with coenzyme Q10 and vitamin D. A number of hypolipidemic drugs are in trial phases and hold promise for statin intolerant patients.

    To see the prevalence of lactose intolerance (LI) and related symptoms following oral lactose challenge in healthy volunteers. Symptoms of abdominal pain, nausea, borborygmi, flatulence, and diarrhea were noted for 24 hours and blood glucose was estimated at 0 hour and 30 minutes after 25 gm oral lactose load to healthy volunteers. Failure to rise blood glucose level ≥ 1.1 mmol/l at 30 minutes after lactose intake from fasting level was taken as lactose malabsorption (LM), i.e., LI. A total of 166 volunteers (123 males, 43 females) with a mean age 34.78 ± 11.45 years participated in this study. Lactose intolerance was found among 85.54% (n = 142, M = 104, F = 38). The main symptoms of LI were diarrhea (n = 83, 58.4.0%), borborygmi (n = 81, 57.04%), abdominal pain (n = 35, 24.65%), and flatulence (n = 27, 19.0%). Lactose intolerance among healthy adults may be common in Bangladesh. Diarrhea and borborygmi were mostly associated symptoms of LI.

    Symptoms burden in chronic rhinosinusitis (CRS) may be assessed by interviews or by means of validated tools such as the 22-item SinoNasal Outcome Test (SNOT-22). However, when only the total SNOT-22 scores are used, the pattern of symptom distribution and heterogeneity in patient symptoms is lost. To use a standardized symptom assessment tool (SNOT-22) on preoperative symptoms to understand symptom heterogeneity in CRS and to aid in characterization of distinguishing clinical features between subgroups. This was a retrospective review of 97 surgical patients with CRS. Symptom-based clusters were derived on the basis of presurgical SNOT-22 scores using unsupervised analysis and network graphs. Comparison between clusters was performed for clinical and demographic parameters, postsurgical symptom scores, and presence or absence of a history of aspirin sensitivity. Unsupervised analysis reveals coclustering of specific symptoms in the SNOT-22 tool. Using symptom-based clustering, patients with CRS were stratified into severe overall (mean total score, 90.8), severe sinonasal (score, 62), moderate sinonasal (score, 40), moderate nonsinonasal (score, 37) and mild sinonasal (score, 16) clusters. The last 2 clusters were associated with lack of history of aspirin sensitivity. The first cluster had a rapid relapse in symptoms postoperatively, and the last cluster demonstrated minimal symptomatic improvement after surgery. Symptom-based clusters in CRS reveal a distinct grouping of symptom burden that may relate to aspirin sensitivity and treatment outcomes.

    2014-06-01

    Full Text Available The tyrosine-protein kinase Tec (TEC is a member of non-receptor tyrosine kinases and has critical roles in cell signaling transmission, calcium mobilization, gene expression, and transformation. TEC is also involved in various immune responses, such as mast cell activation. Therefore, we hypothesized that TEC polymorphisms might be involved in aspirin-exacerbated respiratory disease (AERD pathogenesis. We genotyped 38 TEC single nucleotide polymorphisms in a total of 592 subjects, which comprised 163 AERD cases and 429 aspirin-tolerant asthma controls. Logistic regression analysis was performed to examine the associations between TEC polymorphisms and the risk of AERD in a Korean population. The results revealed that TEC polymorphisms and major haplotypes were not associated with the risk of AERD. In another regression analysis for the fall rate of forced expiratory volume in 1 second (FEV1 by aspirin provocation, two variations (rs7664091 and rs12500534 and one haplotype (TEC_BL2_ht4 showed nominal associations with FEV1 decline (p = 0.03-0.04. However, the association signals were not retained after performing corrections for multiple testing. Despite TEC playing an important role in immune responses, the results from the present study suggest that TEC polymorphisms do not affect AERD susceptibility. Findings from the present study might contribute to the genetic etiology of AERD pathogenesis.

    Proinflammatory proteins like inflammatory cytokines are implicated in myocardial depression and left ventricular remodeling after myocardial infarction. High-dose aspirin inhibits cytokine activation. Therefore, we tested the influence of high-dose aspirin treatment on left ventricular remodeling in mice after myocardial infarction. Mice were treated for 4 weeks with placebo or aspirin (120 mg/kg per day) by Alzet mini-osmotic pumps after ligation of the left anterior descending coronary artery. Serial transthoracic echocardiography was performed at days 1, 7, and 28. Over the 4 weeks, mortality was not different between the groups (placebo 30.8%, aspirin 30.8%). On echocardiography, animals after myocardial infarction exhibited left ventricular dilatation (week 4, end-systolic area, placebo sham 8.9 +/- 1.7 vs. placebo MI 15.9 +/- 2.5 mm(2)), which was not changed by aspirin treatment (week 4, end-systolic area, aspirin MI 14.5 +/- 1.3 mm(2), p= ns vs. placebo MI). The expression of the proinflammatory cytokines TNF and IL-1beta were markedly upregulated in mice with myocardial infarction on placebo. Cytokine expression was significantly reduced by aspirin treatment while collagen deposition was not influenced. Continuous aspirin treatment (120 mg/kg/d) reduces the expression of proinflammatory cytokines after myocardial infarction, but does not affect post-infarct cardiac remodeling and cardiac function.

    Objective There is insufficient evidence on which to base a recommendation for optimal antiplatelet therapy following a stroke while on aspirin. The objective was to compare clopidogrel initiation vs aspirin reinitiation for vascular risk reduction among patients with ischaemic stroke on aspirin at the time of their index stroke. Design Retrospective. Setting We conducted a nationwide cohort study by retrieving all hospitalised patients (≥18 years) with a primary diagnosis of ischaemic stroke between 2003 and 2009 from Taiwan National Health Insurance Research Database. Participants Among 3862 patients receiving aspirin before the index ischaemic stroke and receiving either aspirin or clopidogrel after index stroke during follow-up period, 1623 were excluded due to a medication possession ratio aspirin was prescribed during the follow-up period. Follow-up was from time of the index stroke to admission for recurrent stroke or myocardial infarction, death or the end of 2010. Primary and secondary outcome measures The primary end point was hospitalisation due to a new-onset major adverse cardiovascular event (MACE: composite of any stroke or myocardial infarction). The leading secondary end point was any recurrent stroke. Results Compared to aspirin, clopidogrel was associated with a lower occurrence of future MACE (HR=0.54, 95% CI 0.43 to 0.68, paspirin, clopidogrel initiation was associated with fewer recurrent vascular events than aspirin reinitiation.

    Aspirin-exacerbated respiratory disease (AERD) is recognized as a distinct asthma phenotype. It usually has a severe course accompanied by chronic hyperplastic eosinophilic sinusitis with nasal polyps, blood eosinophilia, and increased concentrations of urinary leukotriene E4 (LTE4). More insightful analysis of individual patients shows this group to be nonhomogeneous. We sought to identify any likely subphenotypes in a cohort of patients with AERD through the application of latent class analysis (LCA). Clinical data from 201 patients with AERD (134 women) were collected from questionnaires. Standard spirometry, atopy traits, blood eosinophilia, and urinary LTE4 concentrations were evaluated. LCA was applied to identify possible AERD subphenotypes. Four classes (subphenotypes) within the AERD phenotype were identified as follows: class 1, asthma with a moderate course, intensive upper airway symptoms, and blood eosinophilia (18.9% of patients); class 2, asthma with a mild course, relatively well controlled, and with low health care use (34.8% of patients); class 3, asthma with a severe course, poorly controlled, and with severe exacerbations and airway obstruction (41.3% of patients); and class 4, poorly controlled asthma with frequent and severe exacerbations in female subjects (5.0% of patients). Atopic status did not affect class membership. Patients with particularly intensive upper airway symptoms had the highest levels of blood eosinophilia and the highest concentrations of urinary LTE4. LCA revealed unique AERD subphenotypes, thus corroborating the heterogeneity of this population. Such discrimination might facilitate more individualized treatment in difficult-to-treat patients.

    Results of trials of aspirin and dipyridamole combined versus aspirin alone for the secondary prevention of vascular events after ischaemic stroke of presumed arterial origin are inconsistent. Our aim was to resolve this uncertainty. We did a randomised controlled trial in which we assigned patients to aspirin (30-325 mg daily) with (n=1363) or without (n=1376) dipyridamole (200 mg twice daily) within 6 months of a transient ischaemic attack or minor stroke of presumed arterial origin. Our primary outcome event was the composite of death from all vascular causes, non-fatal stroke, non-fatal myocardial infarction, or major bleeding complication, whichever happened first. Treatment was open, but auditing of outcome events was blinded. Primary analysis was by intention to treat. This study is registered as an International Standard Randomised Controlled Trial (number ISRCTN73824458) and with (NCT00161070). Mean follow-up was 3.5 years (SD 2.0). Median aspirin dose was 75 mg in both treatment groups (range 30-325); extended-release dipyridamole was used by 83% (n=1131) of patients on the combination regimen. Primary outcome events arose in 173 (13%) patients on aspirin and dipyridamole and in 216 (16%) on aspirin alone (hazard ratio 0.80, 95% CI 0.66-0.98; absolute risk reduction 1.0% per year, 95% CI 0.1-1.8). Addition of the ESPRIT data to the meta-analysis of previous trials resulted in an overall risk ratio for the composite of vascular death, stroke, or myocardial infarction of 0.82 (95% CI 0.74-0.91). Patients on aspirin and dipyridamole discontinued trial medication more often than those on aspirin alone (470 vs 184), mainly because of headache. The ESPRIT results, combined with the results of previous trials, provide sufficient evidence to prefer the combination regimen of aspirin plus dipyridamole over aspirin alone as antithrombotic therapy after cerebral ischaemia of arterial origin.

    To design and validate a new questionnaire for identifying patients with methotrexate (MTX) intolerance, and to determine the prevalence of MTX intolerance in patients with juvenile idiopathic arthritis (JIA) using this questionnaire. The MTX Intolerance Severity Score (MISS) questionnaire was constructed, consisting of 5 domains: stomach ache, nausea, vomiting, sore mouth, and behavioral symptoms. The domains each consisted of 3 questions pertaining to the presence of a symptom upon, prior to (anticipatory), and when thinking of (associative) MTX intake. The MISS questionnaire was validated in 86 patients by determining its discriminative power between patients with and those without MTX intolerance, identified as such by a gold standard (physician's opinion). Using the MISS questionnaire, the prevalence of MTX intolerance was determined in 297 JIA patients. The MISS questionnaire discriminated well between MTX-intolerant and MTX-tolerant patients. A cutoff score of 6 yielded the best sensitivity (88%) and specificity (80%). MTX intolerance was found in 150 (50.5%) of 297 patients. Of 220 patients receiving oral MTX, 98 (44.5%) experienced MTX intolerance, whereas 67.5% of 77 patients receiving parenteral MTX experienced intolerance to the drug (P = 0.001). Our findings indicate that the MISS questionnaire is a highly sensitive and specific tool for the diagnosis of MTX intolerance, and that there is a high prevalence of MTX intolerance among JIA patients. The prevalence of intolerance in patients receiving parenteral MTX exceeds that in patients receiving oral MTX. The frequent occurrence of anticipatory and associative symptoms suggests that classic conditioning plays an important role in MTX intolerance.

    DeVries, Avery; Vercelli, Donata

    2016-03-01

    Asthma and allergic diseases are among the most prevalent chronic noncommunicable diseases of childhood, but the underlying pathogenetic mechanisms are poorly understood. Because epigenetic mechanisms link gene regulation to environmental cues and developmental trajectories, their contribution to asthma and allergy pathogenesis is under active investigation. DNA methylation signatures associated with concurrent disease and with the development of asthma during childhood asthma have been identified, but their significance is not easily interpretable. On the other hand, the characterization of early epigenetic predictors of asthma points to a potential role of epigenetic mechanisms in regulating the inception of, and the susceptibility to, this disease.

    Aspirin failure, defined as occurrence of an acute coronary syndrome despite aspirin use, has been associated with a higher cardiovascular risk profile and worse prognosis. Whether this phenomenon is a manifestation of patient characteristics or failure of adequate platelet inhibition by aspirin has never been studied. We evaluated 174 consecutive patients with acute myocardial infarction. Of them, 118 (68%) were aspirin naive and 56 (32%) were regarded as having aspirin failure. Platelet function was analyzed after ≥72 hours of aspirin therapy in all patients. Platelet reactivity was studied by light-transmitted aggregometry and under flow conditions. Six-month incidence of major adverse coronary events (death, recurrent acute coronary syndrome, and/or stroke) was determined. Those with aspirin failure were older (p = 0.002), more hypertensive (p aspirin-failure group (14.3% vs 2.5% p aspirin failure had lower arachidonic acid-induced platelet aggregation (32 ± 24 vs 45 ± 30, p = 0.003) after aspirin therapy compared to their aspirin-naive counterparts. However, this was not significant after adjusting for differences in baseline characteristics (p = 0.82). Similarly, there were no significant differences in adenosine diphosphate-induced platelet aggregation and platelet deposition under flow conditions. In conclusion, our results suggest that aspirin failure is merely a marker of higher-risk patient profiles and not a manifestation of inadequate platelet response to aspirin therapy.

Dual antiplatelet therapy with clopidogrel and aspirin has been shown to increase the risk of hemorrhage, but the effects of the drugs on laboratory parameters have not been well studied in real-world clinical settings. Therefore, we evaluated and compared the effects of combination therapy with clopidogrel plus aspirin and aspirin monotherapy on laboratory parameters.Methods: We used data from the Nihon University School of Medicine Clinical Data Warehouse obtained between November 2004 and May 2011 to identify cohorts of new users (n = 130 of clopidogrel (75 mg/day plus aspirin (100 mg/day and a propensity score matched sample of new users (n = 130 of aspirin alone (100 mg/day.

    Because of widespread use, nonsteroidal anti-inflammatory drugs (NSAIDs) are the second most common cause of all adverse drug reactions, with hypersensitivity reported in ∼1% of the population. NSAID hypersensitivity can be categorized into five types by the underlying disease, symptoms of reaction, and timing of reaction. These include rhinitis and asthma induced by NSAIDs (also known as aspirin-exacerbated respiratory disease), NSAID-exacerbated cutaneous disease (NECD), urticaria or angioedema induced by multiple NSAIDs, single NSAID-induced reactions, and delayed NSAID reactions. NECD occurs in one-third of patients with chronic urticaria who develop an exacerbation of their urticaria, sometimes with angioedema, typically beginning 30-90 minutes after ingestion of NSAIDs that inhibit cyclooxygenase (COX)-1. In urticaria or angioedema induced by multiple NSAIDs, patients without underlying disease develop urticaria or angioedema 30-90 minutes after ingestion of COX-1-inhibiting NSAIDs including aspirin. Single NSAID-induced reactions are immediate and specific to a single NSAID and are thought to occur because of an IgE-mediated reaction against a specific epitope of the NSAID. Delayed NSAID reactions occur days to weeks after initiating an NSAID. These are T-cell mediated and not amenable to desensitization or rechallenge. Classifying the type of NSAID hypersensitivity is important because many patients with a prior history of urticaria or angioedema induced by multiple NSAIDs will often tolerate aspirin test dose. This would allow the use of an aspirin for primary or secondary prevention in patients with coronary artery disease despite a presumed history of NSAID hypersensitivity.

  10. Obesity and asthma.

    Science.gov (United States)

    Gibson, Peter G

    2013-12-01

    There is a global epidemic of asthma and obesity that is concentrated in Westernized and developed countries. A causal association in some people with asthma is suggested by observations that obesity precedes the onset of asthma and that bariatric surgery for morbid obesity can resolve asthma. The obese asthma phenotype features poor asthma control, limited response to corticosteroids, and an exaggeration of the physiological effects of obesity on lung function, which includes a reduction in expiratory reserve volume and airway closure occurring during tidal breathing. Obesity has important implications for asthma treatment. Increasing corticosteroid doses based on poor asthma control, as currently recommended in guidelines, may lead to overtreatment with corticosteroids in obese asthma. Enhanced bronchodilation, particularly of the small airways, may reduce the component of airway closure due to increased bronchomotor tone and suggests that greater emphasis should be placed on long-acting bronchodilators in obese asthma. The societal implications of this are important: with increasing obesity there will be increasing asthma from obesity, and the need to identify successful individual and societal weight-control strategies becomes a key goal.

  12. Patient's adherence in asthma.

    2007-11-01

    Nonadherence in asthma treatment results in increasing mortality, morbidity, and it is associated with increasing treatment costs. In asthma, adherence rates are often below 50%. Understanding of the needs and behaviors of asthma patients as well as treatment barriers to comply with asthma guidelines is important in developing programs to promote adherence. This article presents information on common types of nonadherence in asthma patients, the causes, and it reviews the literature on interventions to overcome these factors to maximize adherence rates. Although several interventions are effective in improving medication adherence in asthma, only few significantly enhance adherence rates and clinical outcomes of these patients. An improvement in treatment adherence is a complex task, requiring asthma self-management, education programs coupled with educational reinforcements, simplifying treatment planes and applications forms. Good communications skills among clinicians and patient education are also central for improving adherence. Methods to overcoming physician barriers ensure consistency in implementing guideline recommendations in practice.

  15. The mechanism of action of aspirin.

    Vane, J R; Botting, R M

    2003-06-15

    The therapy of rheumatism began thousands of years ago with the use of decoctions or extracts of herbs or plants such as willow bark or leaves, most of which turned out to contain salicylates. Following the advent of synthetic salicylate, Felix Hoffman, working at the Bayer company in Germany, made the acetylated form of salicylic acid in 1897. This drug was named "Aspirin" and became the most widely used medicine of all time. In 1971, Vane discovered the mechanism by which aspirin exerts its anti-inflammatory, analgesic and antipyretic actions. He proved that aspirin and other non-steroid anti-inflammatory drugs (NSAIDs) inhibit the activity of the enzyme now called cyclooxygenase (COX) which leads to the formation of prostaglandins (PGs) that cause inflammation, swelling, pain and fever. However, by inhibiting this key enzyme in PG synthesis, the aspirin-like drugs also prevented the production of physiologically important PGs which protect the stomach mucosa from damage by hydrochloric acid, maintain kidney function and aggregate platelets when required. This conclusion provided a unifying explanation for the therapeutic actions and shared side effects of the aspirin-like drugs. Twenty years later, with the discovery of a second COX gene, it became clear that there are two isoforms of the COX enzyme. The constitutive isoform, COX-1, supports the beneficial homeostatic functions, whereas the inducible isoform, COX-2, becomes upregulated by inflammatory mediators and its products cause many of the symptoms of inflammatory diseases such as rheumatoid and osteoarthritis.

    Salicylates from plant sources have been used for centuries by different cultures to treat a variety of ailments such as inflammation, fever and pain. A chemical derivative of salicylic acid, aspirin, was synthesised and mass produced by the end of the 19th century and is one of the most widely used drugs in the world. Its cardioprotective properties are well established; however, recent evidence shows that it can also act as a chemopreventive agent. Its antithrombotic and anti-inflammatory actions occur through the inhibition of cyclooxygenases. The precise mechanisms leading to its anticancer effects are not clearly established, although multiple mechanisms affecting enzyme activity, transcription factors, cellular signalling and mitochondrial functions have been proposed. This review presents a brief account of the major COX-dependent and independent pathways described in connection with aspirin's anticancer effects. Aspirin's unique ability to acetylate biomolecules besides COX has not been thoroughly investigated nor have all the targets of its primary metabolite, salicylic acid been identified. Recent reports on the ability of aspirin to acetylate multiple cellular proteins warrant a comprehensive study to investigate the role of this posttranslational modification in its anticancer effects. In this review, we also raise the intriguing possibility that aspirin may interact and acetylate cellular molecules such as RNA, and metabolites such as CoA, leading to a change in their function. Research in this area will provide a greater understanding of the mechanisms of action of this drug. PMID:24874482

    To evaluate the scientific evidence for purported intolerance to dietary biogenic amines. MEDLINE was searched for articles in the English language published between January 1966 and August 2001. The keyword biogenic amin* was combined with hypersens*, allerg*, intoler*, and adverse. Additionally, the keywords histamine, tyramine, and phenylethylamine were combined with headache, migraine, urticaria, oral challenge, and oral provocation. Articles were also selected from references in relevant literature. Only oral challenge studies in susceptible patients were considered. Studies with positive results (ie, studies in which an effect was reported) were only eligible when a randomized, double-blind, placebo-controlled design was used. Eligible positive result studies were further evaluated according to a number of scientific criteria. Studies with negative results (ie, studies in which no effect was reported) were examined for factors in their design or methods that could be responsible for a false-negative outcome. Results of methodologically weak or flawed studies were considered inconclusive. A total of 13 oral challenge studies (5 with positive results and 8 with negative results) were found. Three of them (all with positive results) were considered ineligible. By further evaluation of the 10 eligible studies, 6 were considered inconclusive. The 4 conclusive studies all reported negative results. One conclusive study showed no relation between biogenic amines in red wine and wine intolerance. Two conclusive studies found no effect of tyramine on migraine. One conclusive study demonstrated no relation between the amount of phenylethylamine in chocolate and headache attacks in individuals with headache. The current scientific literature shows no relation between the oral ingestion of biogenic amines and food intolerance reactions. There is therefore no scientific basis for dietary recommendations concerning biogenic amines in such patients.

    2014-01-01

    The purpose of this study was to investigate the frequency of enteral feeding intolerance in critically ill septic burn patients, the effect of enteral feeding intolerance on the efficacy of feeding, the correlation between the infection marker (procalcitonin [PCT]) and the nutrition status marker (prealbumin) and the impact of feeding intolerance on the outcome of septic burn patients. From January 2009 to December 2012 the data of all burn patients with the diagnosis of sepsis who were placed on enteral nutrition were analyzed. Septic patients were divided into two groups: group A, septic patients who developed feeding intolerance; group B, septic patients who did not develop feeding intolerance. Demographic and clinical characteristics of patients were analyzed and compared. The diagnosis of sepsis was applied to 29% of all patients. Of these patients 35% developed intolerance to enteral feeding throughout the septic period. A statistically significant increase in mean PCT level and a decrease in prealbumin level was observed during the sepsis period. Group A patients had statistically significant lower mean caloric intake, higher PCT:prealbumin ratio, higher pneumonia incidence, higher Sequential Organ Failure Assessment Maximum Score, a longer duration of mechanical ventilation, and a higher mortality rate in comparison with the septic patients without gastric feeding intolerance. The authors concluded that a high percentage of septic burn patients developed enteral feeding intolerance. Enteral feeding intolerance seems to have a negative impact on the patients' nutritional status, morbidity, and mortality.

    Strict criteria for the diagnosis of temporary gluten intolerance are formulated in the light of the case of an 8-week-old infant with severe diarrhoea and failure to thrive, who recovered on an elimination diet that was gluten-free. 8 weeks later an oral challenge with 2.5 g twice daily of powdered gluten for one day produced diarrhoea, weight loss, and impaired xylose absorption. Gluten was successfully reintroduced into the diet 9 months later without incident. Jejunal histology remains normal after 26 months of a daily diet that contains 5 to 10 g gluten.

    In this study we assessed patient outcomes after complete endoscopic sinus surgery (ESS) and aspirin desensitization for patients with aspirin-exacerbated respiratory disease (AERD). A retrospective chart review was conducted for patients with aspirin challenge-proven AERD who underwent complete ESS followed by aspirin desensitization. Outcomes assessed included need for revision surgery and quality-of-life measures using the 22-item Sino-Nasal Outcomes Test (SNOT-22). Data were collected preoperatively, postoperatively prior to desensitization, and then at intervals post-desensitization through 30 months after aspirin desensitization. A longitudinal linear mixed-effects model was used for data analysis. Thirty-four patients met the inclusion criteria for this study. Thirty-two patients successfully completed aspirin desensitization and were subsequently followed for 30 months after desensitization. Two patients were unable to complete desensitization. Five patients discontinued aspirin maintenance therapy due to gastrointestinal and respiratory side effects. Within the follow-up period, there were only 3 (9.4%) revision sinus surgeries. Notably, 1 of these revision cases occurred in a patient who had discontinued aspirin maintenance therapy. After surgical treatment and prior to desensitization patients had significant reductions in SNOT-22 scores. Our results demonstrate that total SNOT-22 scores remained statistically unchanged from immediate post-desensitization throughout the 30-month follow-up period. Complete sinus surgery followed by timely aspirin desensitization and maintenance therapy is an effective combination in the long-term management of sinus disease in patients with AERD. © 2017 ARS-AAOA, LLC.

    The National Institute for Health and Clinical Excellence (NICE) has issued guidelines on which thromboprophylaxis regimens are suitable following lower limb arthroplasty. Aspirin is not a recommended agent despite being accepted in orthopaedic guidelines elsewhere. We assessed the incidence of fatal pulmonary embolism (PE) and all-cause mortality following elective primary total knee replacement (TKR) with a standardised multi-modal prophylaxis regime in a large teaching district general hospital. We utilised a prospective audit database to identify those that had died within 42 and 90days postoperatively. Data from April 2000 to 2012 were analysed for 42 and 90day mortality rates. There were a total of 8277 elective primary TKR performed over the 12year period. The multi-modal prophylaxis regimen used unless contraindicated for all patients included 75mg aspirin once daily for four weeks. Case note review ascertained the causes of death. Where a patient had been referred to the coroner, they were contacted for post mortem results. The mortality rates at 42 and 90days were 0.36 and 0.46%. There was one fatal PE within 42days of surgery (0.01%) who was taking enoxaparin because of aspirin intolerance. Two fatal PE's occurred at 48 and 57days post-operatively (0.02%). The leading cause of death was myocardial infarction (0.13%). Fatal PE following elective TKR with a multi-modal prophylaxis regime is a very rare cause of mortality. Copyright © 2017 Elsevier B.V.

    Aspirin-exacerbated respiratory disease (AERD) is an inflammatory condition of the respiratory tract and is characterized by overproduction of leukotrienes (LT) and large numbers of circulating granulocyte-platelet complexes. LT production can be suppressed by prostaglandin E(2) (PGE(2)) and the cyclic AMP-dependent protein kinase A (PKA). To determine if PGE(2)-dependent control of LT production by granulocytes is dysregulated in AERD. Granulocytes from well-characterized patients with and without AERD were activated ex vivo and subjected to a range of functional and biochemical analyses. Granulocytes from subjects with AERD generated more LTB4 and cysteinyl LTs than did granulocytes from controls with aspirin-tolerant asthma and controls without asthma. When compared with controls, granulocytes from subjects with AERD had comparable levels of EP(2) protein expression and PGE(2)-mediated cAMP accumulation, yet were resistant to PGE(2)-mediated suppression of LT generation. Percentages of platelet-adherent neutrophils correlated positively with LTB4 generation and inversely with responsiveness to PGE(2)-mediated suppression of LTB(4). The PKA inhibitor H89 potentiated LTB4 generation by control granulocytes but was inactive in granulocytes from individuals with AERD and had no effect on platelet P-selectin induction. Both tonic PKA activity and levels of PKA catalytic gamma subunit protein were significantly lower in granulocytes from individuals with AERD relative to those from controls. Impaired granulocyte PKA function in AERD may lead to dysregulated control of 5-lipoxygenase activity by PGE(2), whereas adherent platelets lead to increased production of LTs, which contributes to the features of persistent respiratory tract inflammation and LT overproduction.

  9. HEREDITARY FRUCTOSE INTOLERANCE – CASE REPORT

    Directory of Open Access Journals (Sweden)

    Jernej Brecelj

    2002-03-01

    Full Text Available Background. Hereditary fructose intolerance is a rare inborn error of carbohydrate metabolism that presents with hypoglicemia, metabolic acidosis and liver decompensation when the patient is exposed to fructose. Diagnosis was established by fructose tolerance test in the past and nowadays mostly by determination of deficient enzyme fructose-1phosphate aldolase (aldolase B activity in hepatic tissue or by molecular genetic means if the mutation is known. Treatment involves elimination (in infants or reduction of fructose and sucrose from the diet and results in improvement in the patient’s clinical status and liver disease.Results. This article presents a patient with hereditary fructose intolerance who was diagnosed 18 years ago on the Department of Pediatric Gastroenterology, Ljubljana Children’s Hospital. At that time oral fructose tolerance test was used to diagnose the disorder. When she was 17 we performed liver biopsy. The enzyme determination showed the absence of aldolase B activity.Conclusions. Only cooperation of different experts enables recognition of rare metabolic disorders which must be prompt to prevent further damage.

  10. Lactose intolerance: lactose tolerance test versus genotyping.

    Science.gov (United States)

    Ridefelt, Peter; Håkansson, Lena D

    2005-07-01

    Adult lactose intolerance, which affects the majority of the population in the world, has been associated with a single nucleotide polymorphism, C-13910T, located upstream of the lactase gene. Adult patients undergoing lactose tolerance tests with lactose challenge and plasma glucose measurements were included in the study comprising 44 Swedes and 7 non-Swedish individuals. A real-time PCR method was established for the genotyping. Out of 51 patients 48 had concordant results on genotyping and lactose tolerance tests, e.g. -13910T/T and -13910C/T genotypes had high glucose elevations. All patients with the heterozygous genotype, -13910C/T, had high glucose elevations, and no gene-dose relationship was observed when comparing maximal glucose increases for cases with -13910C/T and -13910T/T genotypes. Genotyping could replace lactose challenge as a first-stage screening test in adults of European descent, but should be used together with tolerance tests in children and patients where secondary lactose intolerance is suspected.

    PURPOSE This study extends previous community-based studies on the prevalence and clinical characteristics of chemical intolerance in a sample of primary care clinic patients. We evaluated comorbid medical and psychiatric disorders, functional status, and rates of health care use. METHODS A total of 400 patients were recruited from 2 family medicine clinic waiting rooms in San Antonio, Texas. Patients completed the validated Quick Environmental Exposure and Sensitivity Inventory (QEESI) to assess chemical intolerance; the Primary Care Evaluation of Mental Disorders (PRIME-MD) screen for possible psychiatric disorders; the Dartmouth–Northern New England Primary Care Cooperative Information Project (Dartmouth COOP) charts for functional status; and the Healthcare Utilization Questionnaire. RESULTS Overall, 20.3% of the sample met criteria for chemical intolerance. The chemically intolerant group reported significantly higher rates of comorbid allergies and more often met screening criteria for possible major depressive disorder, panic disorder, generalized anxiety disorder, and alcohol abuse disorder, as well as somatization disorder. The total number of possible mental disorders was correlated with chemical intolerance scores (P intolerance were significantly more likely to have poorer functional status, with trends toward increased medical service use when compared with non–chemically intolerant patients. After controlling for comorbid psychiatric conditions, the groups differed significantly only regarding limitations of social activities. CONCLUSIONS Chemical intolerance occurs in 1 of 5 primary care patients yet is rarely diagnosed by busy practitioners. Psychiatric comorbidities contribute to functional limitations and increased health care use. Chemical intolerance offers an etiologic explanation. Symptoms may resolve or improve with the avoidance of salient chemical, dietary (including caffeine and alcohol), and drug triggers. Given greater medication

    Up to 70% of the world population is lactose intolerance. However, there are no epidemiological studies among Chilean pediatric population affected by this condition. Clinical characterization of a series of children who underwent the lactose intolerance breath test for lactose intolerance study, establishing intolerance and malabsorption frequencies, the most frequent symptoms, and test performance depending on the origin. Patients under 18 years old who took the lactose intolerance breath test in the Gastroenterology Laboratory of the Catholic University of Chile, and who were admitted due to clinically suspected lactose intolerance. Malabsorption was considered when there was as an increase of ≥20ppm above the baseline (H2) or ≥34ppm of H2 and methane (CH4) combined. Intolerance was considered when the above was associated with a symptom intensity score ≥7 during registration. The analysis included194 patients aged 1 to17 years of age. Of these, 102 (53%) presented with malabsorption, and 53 (27%) were intolerant. The frequency of lactose intolerance varied from 7.1 to 45.4%, and it occurred more frequently at older ages. The most common reported symptoms were abdominal pain, bloating and rumbling. Lactose malabsorption and intolerance can be investigated from the first years of life using the lactose breath test plus a symptom questionnaire. An increase in the frequency of intolerance with age, and a greater number of positive tests, if they were requested by a gastroenterologist, were observed.

  13. Debates in allergy medicine: food intolerance does not exist.

    Science.gov (United States)

    Dreborg, Sten

    2015-01-01

    The term "intolerance" is not mentioned in the World Allergy Organization (WAO) document on allergy nomenclature. "Intolerance" has been used to describe some non-immunological diseases. However, pediatric gastroenterologists mix allergy and intolerance, e.g. by using the term "cow's milk protein allergy/intolerance (CMPA/I)", lumping together all types of mechanisms for not tolerating cow's milk. The basis for this mix is the fact that double-blind oral food challenges are time-consuming and expensive. Therefore, cow's milk exclusion and reintroduction is proposed to be used in primary care for the diagnosis of CMPA in children with common gastrointestinal (GI) problems such as colic and constipation. This may lead to a widespread use of hypoallergenic formulas in children without proven CMPA. In lay language, intolerance describes "not tolerating". To discuss the reasons why the term "intolerance" should not be used in the area of allergy. Presently, intolerance is not part of the allergy nomenclature. It is used by lay persons to describe "not tolerating". Pediatricians use intolerance to describe non-immunological hypersensitivity such as lactose intolerance which is acceptable. However, using the mixed term CMPA/I describing a variety of gastrointestinal symptoms in children, should be avoided. The WAO Nomenclature does not clearly distinguish between non-IgE-mediated allergy and non-allergic hypersensitivity. The term "intolerance" should not be used within the area of allergy. Intolerance should be better defined and the term restricted to some non-immunological/non-allergic diseases and not mixed with allergy, e.g. by using the term CMPA/I. A revision of the WAO nomenclature is proposed.

    2016-03-01

    Aspirin (acetylsalicylic acid) has become one of the most commonly used drugs, given its role as an analgesic, antipyretic and agent for cardiovascular prophylaxis. Several decades of research have provided considerable evidence demonstrating its potential for the prevention of cancer, particularly colorectal cancer. Broader clinical recommendations for aspirin-based chemoprevention strategies have recently been established; however, given the known hazards of long-term aspirin use, larger-scale adoption of an aspirin chemoprevention strategy is likely to require improved identification of individuals for whom the protective benefits outweigh the harms. Such a precision medicine approach may emerge through further clarification of aspirin's mechanism of action.

  15. Monitoring asthma in childhood

    2015-06-01

    Full Text Available The goal of asthma treatment is to obtain clinical control and reduce future risks to the patient. However, to date there is limited evidence on how to monitor patients with asthma. Childhood asthma introduces specific challenges in terms of deciding what, when, how often, by whom and in whom different assessments of asthma should be performed. The age of the child, the fluctuating course of asthma severity, variability in clinical presentation, exacerbations, comorbidities, socioeconomic and psychosocial factors, and environmental exposures may all influence disease activity and, hence, monitoring strategies. These factors will be addressed in herein. We identified large knowledge gaps in the effects of different monitoring strategies in children with asthma. Studies into monitoring strategies are urgently needed, preferably in collaborative paediatric studies across countries and healthcare systems.

    Cigarette smoking is a well-known health hazard, probably not least for patients suffering from asthma. This review gives a short overview of the effects of passive and active smoking on the inception and outcome with of longitudinal changes in the lung function and mortality of patients...... with asthma. Substantial evidence suggests that smoking affects asthma adversely. Exposure to environmental tobacco smoke, especially maternal smoking in children, may be a significant risk factor for asthma. Such exposure in patients with established asthma is not only associated with more severe symptoms......, but also with a poorer quality of life, reduced lung function, and increased utilisation of health care including hospital admissions. Active smoking does not appear to be a significant risk factor for asthma, but is associated with a worse outcome with regard to both longitudinal changes in lung function...

    Full Text Available Bronchial asthma is a common problem with enormous medical and economics impacts. It is an inflammatory disease of the airways associated with intermittent episodes of bronchospasm. Asthma is not uncommon in the elderly patients. Prevalence of asthma is similar in older and younger adults. Asthma in the elderly patient is underdiagnosed because of false perceptions by both patient and physician. The high incidence of comorbid conditions in the elderly patient makes the diagnosis and management more difficult. Correct diagnosis is demonstrated with spirometry. The goals of asthma treatment are to achieve and maintain control of symptoms and to prevent development of irreversible airflow limitation. Asthma drugs are preferably inhaled because this route minimizes systemic absorption and, thus, improves the ratio of the therapeutic benefit to the potential side-effects in elderly patients.

  6. The role of aspirin-triggered lipoxins in the mechanism of action of aspirin.

    Gilroy, Derek W

    2005-01-01

    Few drugs have treated so many diseases, provided us with so much understanding of their pathogenesis, and tested our scientific creativity over the last 100 years as much as aspirin. Originally, the beneficial effects of aspirin were shown to stem from its inhibition of cyclooxygenase (COX 2)-derived prostanoids, fatty acid metabolites that modulate host defense and regulate the cardiovascular system. However, the inhibition of COX 2 enzyme activity and prostaglandin synthesis has never fully explained aspirin's repertoire of anti-inflammatory effects, leaving many questions pertaining to its true mechanism of action unanswered. Here, data from a series of comparatively recent experiments exploring aspirin's unique ability to acetylate the active site of inducible COX 2 and generate a family of lipid mediators called the epi-Lipoxins will be discussed in light of their ability to exert profound modulatory effects on the innate and adaptive immune systems.

    Shimizu, Hirotaka; Arai, Katsuhiro; Tang, Julian; Hosoi, Kenji; Funayama, Rie

    2017-05-01

    5-Aminosalicylate (5-ASA) is widely used as the first-line drug for ulcerative colitis (UC). 5-ASA is mostly a safe and effective drug, but it can bring about exacerbation due to 5-ASA intolerance. 5-ASA intolerance can be confusing and it can mislead physicians into considering unnecessary treatment escalation, including corticosteroid (CS), biologics, or even surgery. In spite of the clinical importance of 5-ASA intolerance, there have been few studies on its incidence, clinical features, and diagnosis. In order to evaluate the incidence, characteristic symptoms, disease course, and laboratory data of children with 5-ASA intolerance, we retrospectively reviewed the medical records of 80 children with UC. Eleven of 80 children (13.8%) with UC were diagnosed with 5-ASA intolerance. The median time between the initiation of 5-ASA and the onset of 5-ASA intolerance was 10 days (range, 4-20 days) in patients not receiving CS. Drug-induced lymphocyte stimulation test (DLST) was performed in 10 patients, and was positive in eight. C-reactive protein (CRP) increased significantly when exacerbation of colitis symptoms occurred. The incidence of 5-ASA intolerance was relatively high. Besides the challenge test, elevation of CRP and positive DLST appeared to support the diagnosis of 5-ASA intolerance. © 2017 Japan Pediatric Society.

    2016-02-18

    Venous leg ulcers (VLUs) or varicose ulcers are the final stage of chronic venous insufficiency (CVI), and are the most common type of leg ulcer. The development of VLUs on ankles and lower legs can occur spontaneously or after minor trauma. The ulcers are often painful and exudative, healing is often protracted and recurrence is common. This cycle of healing and recurrence has a considerable impact on the health and quality of life of individuals, and healthcare and socioeconomic costs. VLUs are a common and costly problem worldwide; prevalence is estimated to be between 1.65% to 1.74% in the western world and is more common in adults aged 65 years and older. The main treatment for a VLU is a firm compression bandage. Compression assists by reducing venous hypertension, enhancing venous return and reducing peripheral oedema. However, studies show that it only has moderate effects on healing, with up to 50% of VLUs unhealed after two years of compression. Non-adherence may be the principal cause of these poor results, but presence of inflammation in people with CVI may be another factor, so a treatment that suppresses inflammation (healing ulcers more quickly) and reduces the frequency of ulcer recurrence (thereby prolonging time between recurrent episodes) would be an invaluable intervention to complement compression treatments. Oral aspirin may have a significant impact on VLU clinical practice worldwide. Evidence for the effectiveness of aspirin on ulcer healing and recurrence in high quality RCTs is currently lacking. To assess the benefits and harms of oral aspirin on the healing and recurrence of venous leg ulcers. In May 2015 we searched: The Cochrane Wounds Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE and EBSCO CINAHL. Additional searches were made in trial registers and reference lists of relevant publications for

    2003-02-01

    In this paper, we describe the introduction of spectroscopy into the general chemistry laboratory using a series of experiments based on a common substance, aspirin. In the first lab the students synthesize and recrystallize aspirin and take melting points of their product, an aspirin standard, and salicylic acid. The students perform the remaining experiments on a rotating basis where the following four labs run simultaneously: structural characterization of the synthesized aspirin by IR and NMR; analysis of synthesized aspirin and commercial products by UV vis spectroscopy; analysis of synthesized aspirin and commercial products by HPLC; and analysis of calcium in commercial buffered aspirin tablets by AAS. In each of the analysis experiments, students collect, graph, and analyze their data using a spreadsheet. We have found that this series of labs has been very beneficial to our students. From the course evaluations, students indicate that they are beginning to understand how chemistry is applied outside of the classroom.

    BACKGROUND: We evaluated whether rivaroxaban alone or in combination with aspirin would be more effective than aspirin alone for secondary cardiovascular prevention. METHODS: In this double-blind trial, we randomly assigned 27,395 participants with stable atherosclerotic vascular disease to receive...... rivaroxaban (2.5 mg twice daily) plus aspirin (100 mg once daily), rivaroxaban (5 mg twice daily), or aspirin (100 mg once daily). The primary outcome was a composite of cardiovascular death, stroke, or myocardial infarction. The study was stopped for superiority of the rivaroxaban-plus-aspirin group after...... a mean follow-up of 23 months. RESULTS: The primary outcome occurred in fewer patients in the rivaroxaban-plus-aspirin group than in the aspirin-alone group (379 patients [4.1%] vs. 496 patients [5.4%]; hazard ratio, 0.76; 95% confidence interval [CI], 0.66 to 0.86; P

    There is insufficient evidence on which to base a recommendation for optimal antiplatelet therapy following a stroke while on aspirin. The objective was to compare clopidogrel initiation vs aspirin reinitiation for vascular risk reduction among patients with ischaemic stroke on aspirin at the time of their index stroke. Retrospective. We conducted a nationwide cohort study by retrieving all hospitalised patients (≥18 years) with a primary diagnosis of ischaemic stroke between 2003 and 2009 from Taiwan National Health Insurance Research Database. Among 3862 patients receiving aspirin before the index ischaemic stroke and receiving either aspirin or clopidogrel after index stroke during follow-up period, 1623 were excluded due to a medication possession ratio history of atrial fibrillation, valvular heart disease or coagulopathy. Therefore, 1884 patients were included in our final analysis. Patients were categorised into two groups based on whether clopidogrel or aspirin was prescribed during the follow-up period. Follow-up was from time of the index stroke to admission for recurrent stroke or myocardial infarction, death or the end of 2010. The primary end point was hospitalisation due to a new-onset major adverse cardiovascular event (MACE: composite of any stroke or myocardial infarction). The leading secondary end point was any recurrent stroke. Compared to aspirin, clopidogrel was associated with a lower occurrence of future MACE (HR=0.54, 95% CI 0.43 to 0.68, paspirin, clopidogrel initiation was associated with fewer recurrent vascular events than aspirin reinitiation.

  20. Competing Claims: Religious Affiliation and African Americans' Intolerance of Homosexuals.

    Science.gov (United States)

    Ledet, Richard

    2017-01-01

    Literature on religion and political intolerance indicates competing expectations about how Black Protestant church affiliation affects African Americans' attitudes about civil liberties. On the one hand, Black Protestant theology emphasizes personal freedom and social justice, factors generally linked to more tolerant attitudes. On the other hand, Black Protestants tend to be conservative on family and social issues, factors often linked to intolerance of gays and lesbians. Data from the General Social Survey are used to examine the influence of religious group identification, as well as other relevant aspects of religiosity, on political intolerance among African Americans. Results indicate that although other aspects of religion (beliefs and behaviors) help explain variation in political intolerance, Black Protestant church affiliation has no relationship with attitudes about the civil liberties of homosexuals. However, additional tests show that Black Protestant church affiliation significantly predicts intolerance of other target groups (atheists and racists).

  1. Linking obesity and asthma.

    Science.gov (United States)

    Sutherland, E Rand

    2014-04-01

    A growing body of literature suggests that obesity has a significant impact on asthma risk, phenotype, and prognosis. Epidemiological studies have clearly demonstrated that asthma is more likely to occur in obese patients, and health status is impaired in obese individuals with asthma, with obese asthmatics experiencing more symptoms, worse quality of life, increased healthcare use, and increased asthma severity. However, obesity has well-described effects on lung function and mechanics that can lead to symptoms of dyspnea without causing the pathophysiologic changes of asthma. Adding to the challenges of evaluating this association, some studies have failed to demonstrate a robust relationship between obesity and traditional biomarkers of airway inflammation in adult asthmatics, leading to the conclusion that obesity does not necessarily worsen airway inflammation in asthma. In this regard, emerging data suggest that nonatopic mechanisms may be relevant in obese asthmatics, and that these mechanisms may have a direct impact on the response of obese asthmatics to asthma therapies, most notably inhaled glucocorticoids. This article will review selected aspects of the contributions of obesity-related airway and systemic inflammation to asthma, with a focus on the impact of obesity as a modifier of risk, prognosis, and therapeutic response in asthma. © 2014 New York Academy of Sciences.

    The older population has seen the greatest increase in the prevalence of current asthma in recent years. Asthma may begin at any age and when it occurs at an advanced as opposed to a young age, it is often nonatopic, severe, and unremitting. Unfortunately, geriatric-specific guidelines are not available for the diagnosis and treatment of asthma. However, with objective monitoring, avoidance of asthma triggers, appropriate pharmacotherapy, and patient education, the disease can be managed successfully. Copyright © 2017 Elsevier Inc.

    We report two cases of asthma among mink workers. The first case is about a mink farmer who had asthma that was difficult to treat. In the medical history there was no clear relation to work, and no conclusive work relation with peak flow monitoring. He had a positive histamine release test to mink...... urine. The second case is about a mink farm worker, who had an asthma attack when handling mink furs. Peak flow monitoring showed a clear relation to this work, but there were no signs of allergy. We conclude that these two cases suggest an increased risk of asthma among mink workers....

  4. Sediment Burial Intolerance of Marine Macroinvertebrates.

    Full Text Available The marine environment contains suspended particulate matter which originates from natural and anthropogenic sources. Settlement of this material can leave benthic organisms susceptible to smothering, especially if burial is sudden i.e. following storms or activities such as dredging. Their survival will depend on their tolerance to, and their ability to escape from burial. Here we present data from a multi-factorial experiment measuring burial responses incorporating duration, sediment fraction and depth. Six macroinvertebrates commonly found in sediment rich environments were selected for their commercial and/or conservation importance. Assessments revealed that the brittle star (Ophiura ophiura, the queen scallop (Aequipecten opercularis and the sea squirt (Ciona intestinalis were all highly intolerant to burial whilst the green urchin (Psammichinus miliaris and the anemone (Sagartiogeton laceratus, showed intermediate and low intolerance respectively, to burial. The least intolerant, with very high survival was the Ross worm (Sabellaria spinulosa. With the exception of C. intestinalis, increasing duration and depth of burial with finer sediment fractions resulted in increased mortality for all species assessed. For C. intestinalis depth of burial and sediment fraction were found to be inconsequential since there was complete mortality of all specimens buried for more than one day. When burial emergence was assessed O. ophiura emerged most frequently, followed by P. miliaris. The former emerged most frequently from the medium and fine sediments whereas P. miliaris emerged more frequently from coarse sediment. Both A. opercularis and S. laceratus showed similar emergence responses over time, with A. opercularis emerging more frequently under coarse sediments. The frequency of emergence of S. laceratus increased with progressively finer sediment and C. intestinalis did not emerge from burial irrespective of sediment fraction or depth. Finally

    While aspirin is the drug most often used to prevent cardiovascular complications, its discontinuation induces an increased risk of acute coronary syndrome and ischemic stroke in some patients. We hypothesized that infinitesimal concentrations of aspirin could persist in plasma after its discontinuation, thereby inducing a prothrombotic effect that could be due to a modification in the mechanism of action of aspirin via the cyclooxygenase 1 (COX-1) and COX-2 pathways. We studied the effects of ultra-low-dose aspirin (ULDA) as well as those of sc-560 and ns-398, specific COX-1 and COX-2 inhibitors, on induced hemorrhagic time and in a model of laser-induced thrombosis in rats. In the laser-induced thrombosis model, ULDA treatment increased the number of emboli and the duration of embolization, thereby confirming its prothrombotic effect described in previous publications. This effect was also observed in rats pretreated with sc-560 but not in those pretreated with ns-398. We demonstrated that ULDA induced a prothrombotic effect in the rats studied. This strongly suggests that a very small amount of aspirin could remain in the patient's blood after aspirin therapy, leading to cardiovascular complications. This effect may be mediated by the COX-2 pathway. Copyright 2008 S. Karger AG, Basel.

    A combination of warfarin and aspirin is associated with increased bleeding compared with warfarin monotherapy. The aim of the study was to investigate the incidence and appropriateness of the combination of warfarin and aspirin in patients with atrial fibrillation (AF) or mechanical heart valve (MHV). This cross-sectional study included consecutive patients with AF or MHV on chronic warfarin therapy (>3 months) without acute coronary syndrome or have not undergone a revascularization procedure in the preceding year. Medical history, concomitant diseases, and treatment data were acquired through patient interviews and from hospital records. Three hundred and sixty patients (213 with AF, 147 with MHV) were included. In those with AF, a significantly higher warfarin-aspirin combination was observed with concomitant vascular disease (38.8% vs. 14.6%), diabetes (36.6% vs. 16.3%), statin therapy (40% vs. 16.9%), left ventricular systolic dysfunction (33.3% vs. 17.5%) (paspirin combination were concomitant vascular disease, diabetes, and (younger) age in patients with AF and were concomitant AF and male sex in patients with MHV. Interestingly, the incidence of combination therapy was found to increase with a higher HAS-BLED score in both patients with AF and MHV (paspirin was found to be prescribed to patients with AF mainly for the prevention of cardiovascular events, for which warfarin monotherapy usually suffices. On the other hand, co-treatment with aspirin appeared to be underused in patients with MHV.

    The ability of molecules to yield multiple solid forms, or polymorphs, has significance for diverse applications ranging from drug design and food chemistry to nonlinear optics and hydrogen storage. In particular, aspirin has been used and studied for over a century, but has only recently been shown to have an additional polymorphic form, known as form II. Since the two observed solid forms of aspirin are degenerate in terms of lattice energy, kinetic effects have been suggested to determine the metastability of the less abundant form II. Here, first-principles calculations provide an alternative explanation based on free-energy differences at room temperature. The explicit consideration of many-body van der Waals interactions in the free energy demonstrates that the stability of the most abundant form of aspirin is due to a subtle coupling between collective electronic fluctuations and quantized lattice vibrations. In addition, a systematic analysis of the elastic properties of the two forms of aspirin rules out mechanical instability of form II as making it metastable.

  11. Aspirin treatment reduces platelet resistance to deformation.

    The present investigation has evaluated the influence of aspirin, its constituents, and other nonsteroidal anti-inflammatory agents on the resistance of human platelets to aspiration into micropipettes. Aspirin increased the length of platelet extensions into the micropipette over the entire negative tension range of 0.04 to 0.40 dynes/cm after exposure to the drug in vitro or after ingestion of the agent. Other cyclooxygenase inhibitors, ibuprofen and indomethacin, did not increase platelet deformability. The influence of aspirin was mimicked to some degree by high concentrations of salicylic acid, but acetylation of platelets with acetic anhydride had little influence on platelet deformability. Incubation of platelets with both salicylic acid and acetic anhydride had no more effect than salicylic acid alone. Benzoic acid, chemically similar to salicylic acid, had a minimal effect. The studies demonstrate that aspirin makes platelets more deformable, while components of the drug or other nonsteroidal antiinflammatory agents and cyclooxygenase inhibitors do not have the same influence on resistance to deformation.

    Lactose intolerance affects millions of people world-wide and should be suspected specially when evaluating gastrointestinal symptoms in ethnic populations in which it is prevalent. Fortunately, once a diagnosis is made, management is fairly straightforward. The authors discuss symptoms and methods of detection and offer their recommendations for helping patients with this common disorder. Coeliac disease is the end result of 3 processes that culminate in intestinal damage: genetic predisposition, environmental factors, and immunological based inflammation. Epidemiological studies based on serologic tests suggest that the prevalence of coeliac disease has been significantly underestimated. The classic sprue syndrome of steatorrhea and malnutrition may be less common than more subtle and often monosymptomatic presentations of the disease. The authors discuss the diagnostic criteria and the clinical utility of serologic tests.

    The outlook of inflammatory joint diseases has changed significantly with the advent of TNF blockers. However, these advances come with a trade off-risk of infections, especially tuberculosis. The Irish society of rheumatology has proposed guidelines to investigate and treat latent TB infection (LTBI), which is in accordance with majority of international recommendations. This protocol requires that every patient with LTBI should have chemoprophylaxis. INH and different anti-rheumatic drugs are known to cause hepatic and gastrointestinal complications. We sought to investigate the toxicity of adding prophylactic anti-TB medications to different DMARDs and anti-TNF agents. We prospectively documented the course of all patients who were prescribed chemoprophylaxis for LTBI, from August 2007 to August 2008. Arrangements were made for central re-issuing of prescription of INH or rifampicin, after reviewing monthly liver function tests and following telephone interview seeking presence of adverse events. Out of 132 patients who were commenced on different TNF blockers, only 23 patients (17%) were diagnosed with LTBI and were given prophylaxis as per recommended guidelines. Thirty-nine percent (9 out of 23) of patients discontinued INH because of adverse events. Primary reason for discontinuation in these 9 patients was as follows: 3 patients got marked transaminitis (transaminases >5 times the normal limit), 5 patients had non-resolving gastrointestinal intolerance (mainly nausea), and one patient developed non-resolving rash. We have found a significant number of our patients (39%) who could not continue anti-TB prophylaxis due to either gastrointestinal intolerance or hypertransaminesemia.

    BACKGROUND AND PURPOSE: Orthostatic and other stresses trigger tachycardia associated with symptoms of tremulousness, shortness of breath, dizziness, blurred vision, and, often, syncope. It has been suggested that paradoxical cerebral vasoconstriction during head-up tilt might be present in patients with orthostatic intolerance. We chose to study middle cerebral artery (MCA) blood flow velocity (BFV) and cerebral vasoregulation during tilt in patients with orthostatic intolerance (OI). METHODS: Beat-to-beat BFV from the MCA, heart rate, CO2, blood pressure (BP), and respiration were measured in 30 patients with OI (25 women and 5 men; age range, 21 to 44 years; mean age, 31.3+/-1.2 years) and 17 control subjects (13 women and 4 men; age range, 20 to 41 years; mean age, 30+/-1.6 years); ages were not statistically different. These indices were monitored during supine rest and head-up tilt (HUT). We compared spontaneous breathing and hyperventilation and evaluated the effect of CO2 rebreathing in these 2 positions. RESULTS: The OI group had higher supine heart rates (Ppulse pressure (Ptachycardia (Ptachycardia and worsened symptoms of OI; these symptoms and indices were improved within 2 minutes of CO2 rebreathing. The relationships between CO2 and BFV and heart rate were well described by linear regressions, and the slope was not different between control subjects and patients with OI. CONCLUSIONS: Cerebral vasoconstriction occurs in OI during orthostasis, which is primarily due to hyperventilation, causing significant hypocapnia. Hypocapnia and symptoms of orthostatic hypertension are reversible by CO2 rebreathing.

  17. From 'lactose intolerance' to 'lactose nutrition'.

    The concept of lactose intolerance has become embedded in Western medicine and developing economy medicine. It is based on evidence that intestinal lactase activity persists into later childhood and throughout life in only a minority of the world's population, notably northern European-derived populations. These people have the T single nucleotide polymorphism (SNP) of the rs49882359 allele (C/T), also known as C/T-13910, the MCM6 gene which positively influences the lactase LCT gene. Other lactase persistent (LP) populations are found in Africa and the Middle East with different genetic variants. These SNPs represent co-evolution with dairying since the agricultural revolution and nutrient-dependent ecological adaptation. That said, gastrointestinal symptoms considered due to small intestinal lactose malabsorption are poorly correlated with lactase non-persistence (LNP), the situation for most people. With LNP, colonic microbiome lactase enables lactose fermentation to occur so that none is found in faeces. Whether the short chain fatty acids (SCFAs) and gases (hydrogen, carbon dioxide and methane) produced cause symptoms is dose-dependent. Up to 25 g of lactose at any one time can usually be consumed by a LNP person, but its food and meal pattern context, the microbiomic characteristics, age and other factors may alter tolerance. Thus, the notion that lactose intolerance is a disorder or disease of LNP people is misplaced and has been one of cultural perspective. What actually matters is whether a particular dairy product as normally consumed give rise to symptoms. It is, therefore, proposed that lactose tolerance tests be replaced with dairy food tolerance tests.

  18. Nutrition and Asthma

    Full Text Available Increase in the asthma prevalence in many countries over the recent decades, highlights the need for a greater understanding of the risk factors for asthma. Be-cause asthma is the result of interaction between genetic and environmental fac-tors, increasing prevalence is certainly the result of changes in environmental fac-tors because of process of wesernization. That is the reason for higher prevalence in countries where a traditional to a westernized lifestyle occurred earlier. This increasing prevalence has affected both rural and urban communities, suggesting that local environmental factors such as exposure to allergens or industrial air pol-lutions are not the sole cause. In the last few years, nutrition has represented an important conditioning factor of many cardiovascular, gastrointestinal and chronic pulmonary diseases. So it has been hypothesized that dietary constituents influence the immune system and thus, may also be actively involved in the onset of asthma and other allergic diseases. Dietary constituents can play beneficial as well as det-rimental role in asthma. The possible role of diet in the development of asthma can be described as follows: first, a food allergen can cause asthma. Second, there is role of breast-feeding for prevention of asthma later in life. Third, a low intake of antioxidative dietary constituents might be a risk factor for asthma. Moreover, role of cations such as sodium, potassium and magnesium has been described in development of asthma. Finally, intake of fatty acids specially the role of omega-3 and omega-6 fatty acids play important role in cause of asthma.

    $655 million was spent on asthma for 2008-09.Asthma is a chronic respiratory disease that affects millions of people of all ethnicities, ages and genders worldwide. The pathophysiology of asthma is multifaceted, and is characterized by restriction of airflow into and out of the lungs, airway inflammation with increased mucus production, and bronchial hyper-reactivity caused by exposure to environmental irritants and chemicals, often referred to as triggers, which in some cases are modifiable. Asthma triggers include respiratory infections, weather changes, stress, excitement, exercise and other physical activities, allergic hypersensitivity reactions, food additives, animal dander, dust mites, cockroaches, outdoor and indoor pollutants, certain medications and cigarette smoke. Asthma is characterized by recurrent, episodic, reversible symptoms often referred to as asthma exacerbations, or asthma attacks. Asthma symptoms include coughing, shortness of breath, chest tightness and wheezing that most frequently occur at night or in the early morning. Asthma symptoms vary in severity and frequency in affected individuals, and can occur several times a day or week. Asthma symptoms may be mild, moderate, or severe, and are classified according to presenting symptoms and quantitative measurements of lung function using a peak expiratory flow meter (PEF), or of forced expiratory volume in one second (FEV1). Asthma symptoms can be so severe that, if left untreated, death can occur.Exacerbations of asthma symptoms often result in school and work absenteeism, activity intolerance and emergency hospital visits for asthma. Nocturnal asthma exacerbations frequently cause sleeplessness, which may result in daytime fatigue. Asthma symptoms can interfere and disrupt activities of daily life, and can have an unfavorable impact on the quality of life for people with the disease, including children and their caregivers. For this review, quality of life represents how well the asthmatic

    Currently 162-325 mg aspirin is recommended for the treatment of acute coronary syndrome. We tested the effect of an additional loading dose of 250 mg aspirin at the onset of acute coronary syndrome in patients who were already on chronic therapy with 100 mg aspirin. This was a prospective trial in patients presenting with symptoms suggestive of acute coronary syndrome that included a randomized, double-blind, placebo-controlled trial subgroup. An emergency department in a tertiary care center. Consecutive patients with symptoms suggestive of acute coronary syndrome were enrolled, including a cohort already on chronic aspirin therapy. Patients received an intravenous infusion of 250 mg aspirin. Platelet function was measured with a platelet function analyzer in 234 patients before and after aspirin infusion. Aspirin infusion prolonged collagen epinephrine closure times in almost all patients. Aspirin infusion further lowered thromboxane B(2) levels in patients with acute coronary syndrome who were on chronic aspirin therapy before admission. Concomitantly, collagen epinephrine closure times increased by 22% from 223 secs (95% confidence interval, 192-255 secs) before to 273 secs (95% confidence interval, 252-294 secs) after aspirin infusion (p myocardial infarction on daily aspirin therapy (53%) displayed platelet hyperfunction (collagen epinephrine closure times aspirin infusion further decreased platelet function in these patients with ST-elevation myocardial infarction (30% prolongation of collagen epinephrine closure times; p myocardial infarction still displayed platelet hyperfunction (p = .02). Aspirin loading in the emergency room further reduced thromboxane B(2) levels and further inhibited platelet function in many patients with acute coronary syndrome already on 100 mg aspirin.

  1. A Review on the Relationship between Aspirin and Bone Health

    2017-01-01

    Full Text Available Aspirin is a cyclooxygenase inhibitor commonly used in primary prevention of cardiovascular diseases and cancers. Its users are elderly population susceptible to osteoporosis. It also inhibits the synthesis of prostaglandin E2 essential in bone remodeling. This prompts the question whether it can influence bone health among users. This review aimed to summarize the current literature on the use of aspirin on bone health. A literature search on experimental and clinical evidence on the effects of aspirin on bone health was performed using major scientific databases. In vitro studies showed that aspirin could enhance the survival of bone marrow mesenchymal stem cells, the progenitors of osteoblasts, and stimulate the differentiation of preosteoblasts. Aspirin also inhibited the nuclear factor kappa-B (NFκB pathway and decreased the expression of receptor activator of NFκB ligand, thus suppressing the formation of osteoclast. Aspirin could prevent bone loss in animal models of osteoporosis. Despite a positive effect on bone mineral density, the limited human epidemiological studies revealed that aspirin could not reduce fracture risk. A study even suggested that the use of aspirin increased fracture risk. As a conclusion, aspirin may increase bone mineral density but its effect on fracture prevention is inconclusive. More data are needed to determine the effects of aspirin and bone health in human.

    2012-02-03

    BACKGROUND: Aspirin has a significant effect on hemostasis, so it is often recommended that patients taking aspirin discontinue treatment before elective surgery. While off aspirin, these patients may be at risk of thrombosis. The optimum period of time that aspirin should be withheld is controversial. The aim of this study was to establish the duration of the antihemostatic effect of prolonged aspirin therapy. STUDY DESIGN: In a prospective study, 51 healthy volunteers were randomly assigned into 3 groups, each receiving an identical tablet for 14 days. One group received a placebo tablet; individuals in the other two groups received either 75 mg or 300 mg of aspirin once a day. Template bleeding times and specific platelet function testing (using the PFA-100; Dade Behring) were carried out on subjects before therapy and again after its completion until they returned to baseline. RESULTS: Thirty-eight volunteers complied sufficiently with the protocol to provide useful results. All bleeding times normalized within 96 hours and all platelet function tests within 144 hours after stopping aspirin. There was no demonstrable hemostatic defect in any volunteer persisting by or beyond the sixth day after treatment cessation. There was no apparent difference in duration of effect between those taking either 75 mg or 300 mg of aspirin. CONCLUSIONS: This study uses sensitive measures of platelet function to demonstrate the duration of increased bleeding tendency after withdrawal of aspirin therapy. It supports discontinuation of aspirin therapy 5 days before elective surgery (with the operation being performed on the sixth day).

    Arterial stroke is the main cause of poor outcome in childhood tuberculous meningitis. Aspirin has an antithrombotic action at low dose and anti-ischemic and anti-inflammatory properties, which are dose-related. The aim of the study was to explore the possible benefits of aspirin in children with tuberculous meningitis. A total of 146 consecutive children with a diagnosis of probable tuberculous meningitis were studied. Patients were randomized into 3 groups: (1) placebo group, (2) low-dose aspirin group, and (3) high-dose aspirin group. Twenty-nine additional patients who received aspirin before admission were excluded from the randomized study, but continued on low-dose aspirin. Aspirin, irrespective of dose, did not show any significant benefit regarding morbidity (hemiparesis and developmental outcome) and mortality. Aspirin was well tolerated, but 1 death was probably related to aspirin. The fact that the outcome of the high-dose aspirin group compared favorably with the other treatment groups despite younger age and more severe neurological involvement at baseline needs further investigation.

    Last year's "Advances in pediatric asthma: moving toward asthma prevention" concluded that "We are well on our way to creating a pathway around wellness in asthma care and also to utilize new tools to predict the risk for asthma and take steps to not only prevent asthma exacerbations but also to prevent the early manifestations of the disease and thus prevent its evolution to severe asthma." This year's summary will focus on recent advances in pediatric asthma on prenatal and postnatal factors altering the natural history of asthma, assessment of asthma control, and new insights regarding potential therapeutic targets for altering the course of asthma in children, as indicated in Journal of Allergy and Clinical Immunology publications in 2013 and early 2014. Recent reports continue to shed light on methods to understand factors that influence the course of asthma, methods to assess and communicate levels of control, and new targets for intervention, as well as new immunomodulators. It will now be important to carefully assess risk factors for the development of asthma, as well as the risk for asthma exacerbations, and to improve the way we communicate this information in the health care system. This will allow parents, primary care physicians, specialists, and provider systems to more effectively intervene in altering the course of asthma and to further reduce asthma morbidity and mortality.

    Food intolerance is believed to be a source of frequent medical problems in ulcerative colitis (UC), which closely correlate with patients' dietary pattern. Living in an underdeveloped area of China, residents in southwestern region have diverse dietary habits. The objective of this study is to determine the prevalence of food intolerance in the UC patients in this area and to discuss some of the possible risk factors leading to the condition. Food antibodies in serum of 80 patients with active UC were determined by standard enzyme-linked immuno sorbent assay (ELISA). This study examined the risk factors contributing to high titers of food antibodies and the dietary patterns correlating with food intolerance in these demographics. 83.8% of patients (67/80) were found to be seropositive for food intolerance. Patients of female, aged between 20 to 40 and the one who tended to have a high fat diet were tested to be highly seropositive (pintolerance (p>0.05). Active UC patients in southwestern region of China have showed to be high seropositive in food intolerance, particularly in female and young patients. Dietary patterns with high in fat intake seem to have caused high prevalence of seropositivity in food intolerance. Although rice has been taken as staple food and the spicy food has been popular among citizen in this region, these foods have indicated to no effect on food intolerance in this study.

    Three-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors (statins) are one of the most commonly prescribed classes of medications because of their proven cardiovascular benefits. However, statin intolerance occurs in 5% to 20% of patients. Understanding the basis for statin intolerance remains a key issue in preventive medicine. To evaluate the association of statin intolerance with hypothyroidism in a large integrated health care system, including its sex-specific relationship and subsequent statin rechallenge and prescription history. The Intermountain Healthcare electronic medical record database identified patients (n = 2686; males = 1276, females = 1410) with a documentation of intolerance ("allergy") to at least 1 statin. Age and sex similar controls (n = 8103; males = 3892, females = 4211) were identified among patients prescribed statins without documented intolerance. Patients were evaluated for a history of hypothyroidism, development of hypothyroidism, and statin prescription history up to 5 years of follow-up. A total of 30.2% patients (210 males, 16.5%; 602 females, 42.7%) with statin intolerance had a history of hypothyroidism compared with 21.5% of statin-tolerant patients (475 males, 12.2%; 1266 females, 30.1%), for an odds ratio (OR) in the total population of 1.49 (95% confidence interval [CI] 1.34-1.65; P intolerance and hypothyroidism were less likely to be on a statin than their statin-intolerant counterparts without hypothyroidism (hazard ratio 0.84; 95% CI 0.75-0.94; P = .002). Hypothyroidism is more prevalent in those with statin intolerance, both in males and, especially, in females. People with hypothyroidism are less likely to have a prescription for a statin at follow-up than those without hypothyroidism. Copyright © 2014 National Lipid Association. Published by Elsevier Inc.

    Aspirin (acetylsalicylic acid) is widely used for the acute treatment of inflammation and the management of cardiovascular disease. More recently, it has also been shown to reduce the risk of a variety of cancers. The anti-inflammatory properties of aspirin in pain-relief, cardio-protection, and chemoprevention are well-known to result from the covalent inhibition of cyclooxygenase enzymes through nonenzymatic acetylation of key serine residues. However, any additional molecular mechanisms that may contribute to the beneficial effects of aspirin remain poorly defined. Interestingly, studies over the past 50 years using radiolabeled aspirin demonstrated that other proteins are acetylated by aspirin and enrichment with antiacetyl-lysine antibodies identified 33 potential targets of aspirin-dependent acetylation. Herein we describe the development of an alkyne-modified aspirin analogue (AspAlk) as a chemical reporters of aspirin-dependent acetylation in living cells. When combined with the Cu(I)-catalyzed [3 + 2] azide-alkyne cycloaddition, this chemical reporter allowed for the robust in-gel fluorescent detection of acetylation and the subsequent enrichment and identification of 120 proteins, 112 of which have not been previously reported to be acetylated by aspirin in cellular or in vivo contexts. Finally, AspAlk was shown to modify the core histone proteins, implicating aspirin as a potential chemical-regulator of transcription.

Previous research has observed significant levels of inappropriate aspirin use for primary CVD prevention in some European populations, but the degree to which aspirin is overutilized in the US remains unknown. This study examined the association between regular aspirin use and demographic/clinical factors in a population-based sample of adults without a clinical indication for aspirin for primary prevention.Methods: A cross-sectional analysis was performed using 2010–2012 data from individuals aged 30–79 years in the Marshfield Epidemiologic Study Area (WI, USA. Regular aspirin users included those who took aspirin at least every other day.Results: There were 16,922 individuals who were not clinically indicated for aspirin therapy for primary CVD prevention. Of these, 19% were regular aspirin users. In the final adjusted model, participants who were older, male, lived in northern Wisconsin, had more frequent medical visits, and had greater body mass index had significantly higher odds of regular aspirin use (P<0.001 for all. Race/ethnicity, health insurance, smoking, blood pressure, and lipid levels had negligible influence on aspirin use. A sensitivity analysis found a significant interaction between age and number of medical visits, indicating progressively more aspirin use in older age groups who visited their provider frequently.Conclusion: There was evidence of aspirin overutilization in this US population without CVD. Older age and more frequent provider visits were the strongest predictors of inappropriate aspirin use. Obesity was the only significant

    The effects of therapy with aspirin 300 mg/day and with combined aspirin 100 mg/day plus clopidogrel 75 mg/day on platelet function were compared in patients with diabetes mellitus and coronary artery disease and impaired antiplatelet responses to aspirin 100 mg/day. The study population consisted of 151 outpatients with type II diabetes mellitus and coronary artery disease who were taking aspirin 100 mg/day. Of the 151 patients, a subgroup of subjects with impaired aspirin response were selected on the basis of the results of platelet aggregometry. Nonresponsiveness to aspirin was defined as mean aggregation > or =69% with 3 micromol/L adenosine diphosphate and mean aggregation > or =70% with 2 micromol/L collagen. Aspirin semiresponders were defined as meeting 1 but not both of these criteria. Nonresponders and semiresponders were randomized equally to aspirin 300 mg/day and aspirin 100 mg/day plus clopidogrel 75 mg/day, and aggregation tests were repeated after 2 weeks. Sixty of the 151 patients with diabetes (40%) were found to respond to aspirin inadequately. Platelet aggregation induced by adenosine diphosphate and collagen decreased significantly after aspirin 300 mg/day or combined therapy. Combined treatment was found to have a stronger inhibitory effect on platelet aggregation induced by adenosine diphosphate than aspirin 300 mg/day (p = 0.002). Impaired aspirin response was resolved by increasing the aspirin dose or adding clopidogrel to aspirin (p <0.0001 for each). However, desired platelet inhibition was achieved in significantly more patients by combined treatment than by aspirin 300 mg/day (p <0.05). In conclusion, aspirin 100 mg/day does not inhibit platelet function adequately in a significant number of patients with diabetes mellitus and coronary artery disease. Increasing the aspirin dose to 300 mg/day or adding clopidogrel to aspirin can provide adequate platelet inhibition in a significant number of those patients with impaired responses to

    Last year’s Advances in Pediatric Asthma: Moving Toward Asthma Prevention concluded that: “We are well on our way to creating a pathway around wellness in asthma care and also to utilize new tools to predict the risk for asthma and take steps to not only prevent asthma exacerbations but also to prevent the early manifestations of the disease and thus prevent its evolution to severe asthma.” This year’s summary will focus on recent advances in pediatric asthma on pre- and postnatal factors altering the natural history of asthma, assessment of asthma control, and new insights regarding potential therapeutic targets for altering the course of asthma in children as indicated in Journal of Allergy and Clinical Immunology publications in 2013 and early 2014. Recent reports continue to shed light on methods to understand factors that influence the course of asthma, methods to assess and communicate levels of control, and new targets for intervention as well as new immunomodulators. It will now be important to carefully assess risk factors for the development of asthma as well as the risk for asthma exacerbations and to improve the way we communicate this information in the health care system. This will allow parents, primary care physicians, specialists and provider systems to more effectively intervene in altering the course of asthma and to further reduce asthma morbidity and mortality.

In this review, we describe the seminal trials of aspirin use in the context of current guidelines, discuss factors that may influence the effectiveness of aspirin therapy for cardiovascular disease prevention, and briefly examine patterns of use. The body of evidence supports a role for aspirin in both secondary and primary prevention of cardiovascular events in selected population groups, but practice patterns may be suboptimal. As a simple and inexpensive prophylactic measure for cardiovascular disease, aspirin use should be carefully considered in all at-risk adult patients, and further measures, including patient education, are necessary to ensure its proper use. © 2013 Marshfield Clinic.

    DESCRIPTION (provided by applicant): Substantial evidence supports the effectiveness of aspirin for cancer chemoprevention in addition to its well-established role in cardiovascular protection. In recent meta-analyses of randomized controlled trials in humans, daily aspirin use reduced incidence, metastasis and mortality from several common types of cancer, especially colorectal cancer. The mechanism(s) by which aspirin exerts an anticancer benefit is uncertain; numerous effects have been described involving both cyclooxygenase-dependent and -independent pathways. |

    We evaluated whether rivaroxaban alone or in combination with aspirin would be more effective than aspirin alone for secondary cardiovascular prevention. In this double-blind trial, we randomly assigned 27,395 participants with stable atherosclerotic vascular disease to receive rivaroxaban (2.5 mg twice daily) plus aspirin (100 mg once daily), rivaroxaban (5 mg twice daily), or aspirin (100 mg once daily). The primary outcome was a composite of cardiovascular death, stroke, or myocardial infarction. The study was stopped for superiority of the rivaroxaban-plus-aspirin group after a mean follow-up of 23 months. The primary outcome occurred in fewer patients in the rivaroxaban-plus-aspirin group than in the aspirin-alone group (379 patients [4.1%] vs. 496 patients [5.4%]; hazard ratio, 0.76; 95% confidence interval [CI], 0.66 to 0.86; Paspirin group (288 patients [3.1%] vs. 170 patients [1.9%]; hazard ratio, 1.70; 95% CI, 1.40 to 2.05; Paspirin group as compared with 378 (4.1%) in the aspirin-alone group (hazard ratio, 0.82; 95% CI, 0.71 to 0.96; P=0.01; threshold P value for significance, 0.0025). The primary outcome did not occur in significantly fewer patients in the rivaroxaban-alone group than in the aspirin-alone group, but major bleeding events occurred in more patients in the rivaroxaban-alone group. Among patients with stable atherosclerotic vascular disease, those assigned to rivaroxaban (2.5 mg twice daily) plus aspirin had better cardiovascular outcomes and more major bleeding events than those assigned to aspirin alone. Rivaroxaban (5 mg twice daily) alone did not result in better cardiovascular outcomes than aspirin alone and resulted in more major bleeding events.

    2012-01-01

    Currently available antiplatelet drugs interfere with the process of platelet activation and aggregation by selectively blocking key enzymes involved in the synthesis of platelet agonists, or membrane receptors mediating activation signals. Pharmacological interference with critical molecular pathways of platelet activation and aggregation may reduce the risk of atherothrombotic complications through mechanisms that are also responsible for an increased risk of bleeding. Acetylsalicylic acid (aspirin) represents a prototypic antiplatelet agent. The aim of this chapter is to integrate our current understanding of the molecular mechanism of action of aspirin with the results of clinical trials and epidemiological studies assessing its efficacy and safety. Moreover, the antiplatelet properties of reversible inhibitors of the same drug target will also be reviewed.

    2016-11-01

    A severe neurological abnormality has not been previously described in individuals with hereditary fructose intolerance, which typically presents early in childhood with severe metabolic acidosis and hypoglycemia. We describe a boy who by age five years had required multiple admissions to the pediatric intensive care unit for an aggressive and atypical, relapsing and remitting neuropathy with features of acute motor axonal neuropathy (AMAN). It was later discovered that he also had undiagnosed hereditary fructose intolerance, and the severity and frequency of his neurological episodes diminished following an exclusion diet. His asymptomatic younger brother was diagnosed with hereditary fructose intolerance on screening. He is on a fructose-free diet and has not developed neurological symptoms. Ongoing low-level exposure to fructose prior to diagnosis may have contributed to our patient's neurological dysfunction. Early diagnosis and treatment may prevent neurological complications of hereditary fructose intolerance. Copyright © 2016 Elsevier Inc. All rights reserved.

  13. Lysinuric protein intolerance presenting with multiple fractures

    Jennifer E. Posey

    2014-01-01

    Full Text Available Lysinuric protein intolerance (LPI is a rare autosomal recessive inborn error of metabolism caused by mutations in SLC7A7, which encodes a component of the dibasic amino acid transporter found in intestinal and renal tubular cells. Patients typically present with vomiting, diarrhea, irritability, failure to thrive, and symptomatic hyperammonemia after protein-rich meals. Long-term complications may include pulmonary alveolar proteinosis, renal disease, and osteoporosis. We present a 5-year-old male who was followed in our skeletal dysplasia clinic for 3 years for multiple fractures, idiopathic osteoporosis, and short stature in the absence of typical features of LPI. Whole exome sequencing performed to determine the etiology of the osteoporosis and speech delay identified a nonsense mutation in SLC7A7. Chromosome microarray analysis identified a deletion involving the second allele of the same gene, and biochemical analysis supported the diagnosis of LPI. Our patient's atypical presentation underscores the importance of maintaining a high index of suspicion for LPI in patients with unexplained fractures and idiopathic osteoporosis, even in the absence of clinical symptoms of hyperammonemia after protein rich meals or other systemic features of classical LPI. This case further demonstrates the utility of whole exome sequencing in diagnosis of unusual presentations of rare disorders for which early intervention may modify the clinical course.

    We conducted two studies to test whether modern health worries (MHWs) were associated with central features of a condition called idiopathic environmental intolerance (IEI) and medical care utilization. In Study 1, 474 Internet users completed an Internet-based questionnaire that assessed MHWs, IEI features, and medical care utilization. In Study 2, the diagnostic specificity of MHWs was investigated by comparing the level of MHWs of three diagnostic groups: 46 people with IEI, 38 people with somatoform disorder but without IEI, and 46 people with neither IEI nor somatoform disorder. The good psychometric properties of the MHW scale were confirmed. MHWs were related to various features of IEI, and people who met IEI case criteria showed consistently higher levels of MHWs compared with people without IEI. The link between MHWs and number of doctor visits was mediated by perceived IEI complaints. In Study 2, the MHW scale effectively discriminated the IEI group from the non-IEI groups. These results suggest that MHWs may contribute to the development of IEI. However, only prospective longitudinal studies will enable us to determine the predictive importance of MHWs for later development of IEI.

    Garland, Emily M; Celedonio, Jorge E; Raj, Satish R

    2015-09-01

    Postural tachycardia syndrome (POTS) is a form of chronic orthostatic intolerance for which the hallmark physiological trait is an excessive increase in heart rate with assumption of upright posture. The orthostatic tachycardia occurs in the absence of orthostatic hypotension and is associated with a >6-month history of symptoms that are relieved by recumbence. The heart rate abnormality and orthostatic symptoms should not be caused by medications that impair autonomic regulation or by debilitating disorders that can cause tachycardia. POTS is a "final common pathway" for a number of overlapping pathophysiologies, including an autonomic neuropathy in the lower body, hypovolemia, elevated sympathetic tone, mast cell activation, deconditioning, and autoantibodies. Not only may patients be affected by more than one of these pathophysiologies but also the phenotype of POTS has similarities to a number of other disorders, e.g., chronic fatigue syndrome, Ehlers-Danlos syndrome, vasovagal syncope, and inappropriate sinus tachycardia. POTS can be treated with a combination of non-pharmacological approaches, a structured exercise training program, and often some pharmacological support.

    Most pharmacists know that aspirin's origins lie with willow bark, but they may be unaware of its role in the development of the pharmaceutical industry. Evolving from salacin (the active ingredient in many plant remedies) to salicylic acid (an analgesic in its own right) to the more effective, less toxic acetylsalicylic acid, this pain reliever cornered the nonsteroidal anti-inflammatory market for more than 70 years. It helped the dye industry branch into pharmaceuticals, and is now used in multiple indications.

  17. Aspirin for primary prevention of cardiovascular disease in diabetes mellitus

    Pignone, Michael; Williams, Craig D.

    2011-01-01

    Aspirin is effective for the prevention of cardiovascular events in patients with a history of vascular disease, as so-called secondary prevention. In general populations with no history of previous myocardial infarction or stroke, aspirin also seems useful for primary prevention of cardiovascular events, although the absolute benefits are smaller than those seen in patients with previous cardiovascular disease. Patients with diabetes mellitus are at an increased risk of cardiovascular events, but new trials have raised questions about the benefit of aspirin for primary prevention in patients with this disorder. This Review comprehensively examines the basic pharmacology of aspirin and provides an overview of the randomized, controlled trials of aspirin therapy that have included patients with diabetes mellitus. On the basis of currently available evidence from primary prevention trials, aspirin is estimated to reduce the relative risk of myocardial infarction and stroke by about 10% in patients with diabetes mellitus; however, aspirin also increases the risk of gastrointestinal bleeding. As such, low-dose aspirin therapy (75–162 mg) is reasonable for patients with diabetes mellitus and a 10-year risk of cardiovascular events >10%. Results from upcoming large trials will help clarify the effects of aspirin with greater precision, including whether the benefits differ between men and women. PMID:20856266

    Studies have shown that aspirin and metformin play important roles in chemoprevention and repression of breast cancers, even though the exact mechanism remains unclear. Aspirin is capable of stimulating apoptosis through prostaglandin-dependent or prostaglandin-independent pathways. Metformin inhibits cell growth by enhancing the tumor suppressive function of transforming growth factor (TGF-β). In the present study, we report a new link between aspirin, metformin, TGF-β1 and murine breast cancer inhibition. Specifically, we showed that aspirin and metformin enhanced 4T1 cell apoptosis by inducing secretion of TGF-β1, whereas estradiol weakened the effect.

  19. NO-aspirin: mechanism of action and gastrointestinal safety.

    Nitric oxide-releasing aspirins are new chemical entities obtained by adding a nitric oxide-releasing moiety to aspirin. NCX-4016 is the prototype of this family of molecules. NCX-4016 consists of the parent molecule (aspirin) linked to a 'spacer' via an ester linkage, which is in turn connected to a nitric oxide-releasing moiety. Both aspirin and nitric oxide moieties of NCX-4016 contribute to its effectiveness, the latter occurring via both cyclic guanosyl monophosphate-dependent and -independent mechanisms. In vitro studies have shown that NCX-4016 inhibits platelet aggregation induced by aspirin-sensitive (arachidonic acid) and aspirin-insensitive (thrombin) agonist. In contrast to aspirin, NCX-4016 exerts a multilevel regulation of inflammatory target, including caspase-1 and NF-kappaB. This broad spectrum of activities translates to an increased potency of this drug in modulating cardiovascular inflammation. Human studies have shown, that while nitric oxide-aspirin maintains its anti-thrombotic activity, it spares the gastrointestinal tract. Indeed, a 7-day course of NCX-4016 results in 90% reduction of gastric damage caused by equimolar doses of aspirin. Further studies are ongoing to define whether this superior anti-inflammatory and anti-thrombotic profile translates in clinical benefits in patients with cardiovascular diseases.

    Polyphenol-aspirin interactions were recently identified; however, the interaction mode and underlying mechanisms remained elusive. Here, we quantitatively assessed the potential interactions among two important polyphenolic compounds, caffeic acid (CA) and protocatechualdehyde (Pro), and aspirin in the AA-induced platelet aggregation model by applying the isobologram and universal response surface approach (URSA) methods. A molecular docking approach and an originally developed platelet-associated aspirin clearance approach (PAACA) were then applied to explore the potential interaction mechanisms. Although Pro and CA themselves exhibited weak inhibitory effect on arachidonic acid (AA)-induced platelet aggregation and the production of thromboxane B₂ (TXB₂), both Pro and CA potentiated aspirin action in a synergistic manner. The most prominent synergism was found between Pro and aspirin. Pro formed a stable complex into the cyclooxygenase-1 (COX-1) channel by in silico docking and significantly promoted the platelet-associated aspirin clearance, suggesting that the Pro interaction with COX-1 was favorable to the binding of aspirin with COX-1. Taken together, our findings suggest that the capacity of Pro and potentially other structurally similar polyphenolic compounds on promoting the binding of aspirin on platelet COX-1 might be the main mechanism of their synergism with aspirin. © Georg Thieme Verlag KG Stuttgart · New York.

    1996-01-01

    Full Text Available Asthma is a complex disease which is due to the interaction of an unknown number of genes with strong environmental factors. Segregation analysis suggests the presence of major genes underlying asthma and atopy. Different genetic effects have been recognized which predispose to generalized atopy, or modify the atopic response to particular allergens, or enhance bronchial inflammation, or modify bronchial tone. These known genes or genetic loci do not account for all of the familial clustering of asthma and atopy. Many studies are now under way to identify the remaining genes.

    GAD symptoms are associated with greater negative urgency, a dimension of impulsivity defined as the tendency to act rashly when distressed. This study examined the degree to which intolerance of negative emotional states and intolerance of uncertainty account for the association between negative urgency and GAD symptoms. An analysis of indirect effects evaluated whether intolerance of negative emotions and intolerance of uncertainty uniquely account for the association between negative urgency and GAD symptom severity. Undergraduate students (N = 308) completed measures of GAD symptoms, trait anxiety, negative urgency, distress tolerance, and intolerance of uncertainty. Greater symptoms of GAD, intolerance of negative emotional states, and intolerance of uncertainty were associated with greater negative urgency. There was an indirect relationship between negative urgency and GAD symptoms through intolerance of negative emotional states and intolerance of uncertainty even when controlling for trait anxiety. Intolerance of negative emotional states and intolerance of uncertainty each had an indirect relationship with GAD severity through negative urgency, suggesting possible bi-directional relations. Future studies should examine the role of intolerance of negative emotional states and intolerance of uncertainty in the impulsive behavior of individuals with GAD, and whether impulsive behavior reinforces these processes.

    Chocolate is traditionally considered as allergenic for predisposed subjects although many immunologic reactions are erroneously evaluated as allergic, due to misleading procedures. Therefore the term intolerance has been more properly employed. After summarizing the negative effects of chocolate, especially in children, we stress that the diagnosis of chocolate intolerance should be based upon reliable studies, including elimination/provocation tests in a double-blind fashion.

    Orthostatic intolerance is typically thought to be sporadic and attributed to cerebral autonomic dysfunction. We sought to identify families with inherited autonomic dysfunction manifest as symptomatic orthostatic intolerance to characterize mode of inheritance and clinical features. Sixteen families with two or more first- or second-degree relatives with autonomic dysfunction and orthostatic intolerance were enrolled. A clinical diagnosis of autonomic dysfunction defined by symptomatic orthostatic intolerance diagnosed by head-up tilt table testing was confirmed for each proband. Clinical features and evaluation were obtained from each proband using a standardized intake questionnaire, and family history information was obtained from probands and available relatives. Comprehensive pedigree analysis of 16 families (39 individuals with orthostatic intolerance and 40 individuals suspected of having orthostatic intolerance) demonstrated dominant transmission of autonomic dysfunction with incomplete penetrance. Affected individuals were predominantly female (71.8%, 28/39; F:M, 2.5:1). Male-to-male transmission, although less common, was observed and demonstrated to transmit through unaffected males with an affected parent. Similar to sporadic orthostatic intolerance, probands report a range of symptoms across multiple organ systems, with headaches and neuromuscular features being most common. Familial occurrence and vertical transmission of autonomic dysfunction in 16 families suggest a novel genetic syndrome with dominant transmission, incomplete penetrance, and skewing of the sex ratio. Elucidation of potential genetic contributions to orthostatic intolerance may inform therapeutic management and identification of individuals at risk. Adolescent evaluation should include identification and treatment of potential at-risk relatives. Copyright © 2016 Elsevier Inc. All rights reserved.

  10. ESPRIT: is aspirin plus dipyridamole superior to aspirin alone in TIA or minor stroke patients?

    Science.gov (United States)

    Rouhl, R P W; Lodder, J

    2008-11-01

    Transient ischemic attack (TIA) or a (minor) ischemic stroke increases the risk of a recurrent stroke or death. Antiplatelet therapy with aspirin or clopidogrel is, in the absence of a potential cardiac embolic source, common practice to lower this risk. Until recently, adjuvant dipyridamole or low intensity oral anticoagulation were not generally prescribed in secondary prevention. In this article, we will summarize and discuss the published results of the European/Australasian Stroke Prevention in Reversible Ischemia Trial (ESPRIT). In this trial, treatments with anticoagulants, aspirin alone and the combination of aspirin plus dipyridamole were compared, in a multicenter, three-armed, randomized, open-label study in patients with TIA or minor stroke.

    Lactose intolerance related to primary or secondary lactase deficiency is characterized by abdominal pain and distension, borborygmi, flatus, and diarrhea induced by lactose in dairy products. The biological mechanism and lactose malabsorption is established and several investigations are available, including genetic, endoscopic and physiological tests. Lactose intolerance depends not only on the expression of lactase but also on the dose of lactose, intestinal flora, gastrointestinal motility, small intestinal bacterial overgrowth and sensitivity of the gastrointestinal tract to the generation of gas and other fermentation products of lactose digestion. Treatment of lactose intolerance can include lactose-reduced diet and enzyme replacement. This is effective if symptoms are only related to dairy products; however, lactose intolerance can be part of a wider intolerance to variably absorbed, fermentable oligo-, di-, monosaccharides and polyols (FODMAPs). This is present in at least half of patients with irritable bowel syndrome (IBS) and this group requires not only restriction of lactose intake but also a low FODMAP diet to improve gastrointestinal complaints. The long-term effects of a dairy-free, low FODMAPs diet on nutritional health and the fecal microbiome are not well defined. This review summarizes recent advances in our understanding of the genetic basis, biological mechanism, diagnosis and dietary management of lactose intolerance.

    Lactose malabsorption is a common condition caused by reduced expression or activity of lactase in the small intestine. In such patients, lactose intolerance is characterized by abdominal symptoms (e.g. nausea, bloating, and pain) after ingestion of dairy products. The genetic basis of lactose malabsorption is established and several tests for this condition are available, including genetic, endoscopic, and H2-breath tests. In contrast, lactose intolerance is less well understood. Recent studies show that the risk of symptoms after lactose ingestion depends on the dose of lactose, lactase expression, intestinal flora, and sensitivity of the gastrointestinal tract. Lactose intolerance has recently been defined as symptoms developing after ingestion of lactose which do not develop after placebo challenge in a person with lactose maldigestion. Such blinded testing might be especially important in those with functional gastrointestinal diseases in whom self-reported lactose intolerance is common. However, placebo-controlled testing is not part of current clinical practice. Updated protocols and high-quality outcome studies are needed. Treatment options of lactose intolerance include lactose-reduced diet and enzyme replacement. Documenting the response to multiple doses can guide rational dietary management; however, the clinical utility of this strategy has not been tested. This review summarizes the genetic basis, diagnosis, and treatment of lactose malabsorption and intolerance. PMID:24917953

    To investigate the association between ibuprofen use and pulmonary function in children with Asthma. Ninety 9- to 10-year-old children were classified into 3 groups: Study group, mild to moderate stable asthmatic children with self-reported aspirin allergy and no history of anaphylaxis; Allergy control group: atopic children (allergic rhinitis/atopic dermatitis); Healthy control group: non-atopic healthy children. None of the participants in the atopic and healthy control groups had a history of aspirin allergy. All received ibuprofen 4 times a day for 3 consecutive days. Forced expiratory volume in the first second (FeV1) and fractional exhaled nitric oxide (FeNO) measurements were performed before and after ingestion of ibuprofen daily for 3 days. In the study group, a decrease in FeV1 and increase in FeNO levels were observed after taking ibuprofen for 2 days. The atopic control group showed only an increase in FeNO but not FEV1. In the healthy control group, both FeV1 and FeNO were unchanged from baseline. The results showed that cross-reactive non-steroidal anti-inflammatory drug hypersensitivity may exist between ibuprofen and aspirin. This raises the possibility that asthma exacerbation could be mediated by ibuprofen ingestion.

    Aspirin use is necessary after a coronary angioplasty. It should not be used in patients with a history of hypersensitivity. However, rapid desensitization protocols have been reported to allow its use in such patients. One of these protocols consists in the administration of progressive doses of aspirin, from 1 to 100 mg in a period of 5.5 hours, in a controlled environment. We report four male patients aged 45,49, 59 and 73 years with a history of aspirin hypersensitivity, who were subjected to a coronary angioplasty. In all, the rapid aspirin desensitization protocol was successfully applied, allowing the use of the drug after the intervention without problems.

    An inspection apparatus for aspirin tablets utilizing image processing technology was developed. One side of a tablet consists of aspirin layer and another side consists of alkiline layer. The alkaline layer is opaque at all but the aspirin layer is translucent. Image of overall configuration of the tablet is taken in CCD camera by illumination from all surrounding sides. The area is measured by using these images. Then, when switching off the surrounding illumination and illuminating the aspirin side, only aspirin side layer shines. The area is determined by taking the image in CCD. Aspirin content is calculated by the ratio of overall images to aspirin image and the predetermined tablet weight. Tablets of different aspirin content were prepared, and the content determined by this method and the chemically determined contents were compared. High correlation was found between both contents, indicating the validity of the image processing method. When the aspirin content is out of 330 {plus minus} 10mg, the controlling mechanism works, by which unmanned operation will be possible. 8 figs.

    Vascular Endothelial Growth Factor (VEGF) is an important angiogenesis factor involved in pathophysiology of cardiovascular diseases. Controlling this factor's level in the serum might have significant prognostic outcomes. Twenty-four patients undergoing coronary artery bypass grafting were prospectively categorized into two groups according to aspirin administration before surgery. Vascular Endothelial Growth Factor levels were compared and correlated and adjusted with platelets count between two groups in the serum, before and after the surgery. Serum creatine kinase (CK) levels were determined before and after the operation in parallel to other clinical data. Vascular Endothelial Growth Factor levels were significantly lower in patients of the aspirin group compared to those of the non-aspirin group; 94+/-61 vs. 241+/-118 pg/ml, p=0.0003, respectively, this-despite an absence of difference in the platelet count between the groups. These titers decreased postoperatively in both groups, 94+/-61 to 10+/-9 pg/ml, p=0.001 in aspirin group and from 241+/-118 to 84+/-54 pg/ml, p=0.001 in control group. Serum creatine kinase levels were higher in the non-aspirin group, 214+/-83 u/l compared to 70+/-32 u/l in the aspirin group. Creatine kinase levels increased significantly postoperatively in both groups; however, the aspirin group had a significantly lower creatine kinase levels compared to non-aspirin group, 107+/-51 vs. 401+/-127 u/l, respectively, p=<0.0001. A significant correlation was seen between VEGF levels and platelets count in both groups, r=0.5. Aspirin treated patients have lower Vascular Endothelial Growth Factor titer levels in the perioperative course. This difference between the aspirin and the non-aspirin group is not accounted for by the platelets count.

    The role of acetylsalicylic acid (aspirin) as a chemo-preventive and adjuvant therapeutic agent for cancers is generating attention. Mounting evidence indicates that aspirin reduces the incidence and mortality of certain obesity-related cancers, particularly colorectal cancer. In endometrial cancer, previous studies examining the effect of aspirin remain inconsistent as to the reduction in the risk of endometrial cancer. While some evidence indicates protective effects in obese women, other studies have showed a potential deleterious effect of these medications on endometrial cancer outcomes. However, exposure measurement across studies has been inconsistent in recording dose, duration, and frequency of use; thus making comparisons difficult. In this article, we review the evidence for the association between endometrial cancer and obesity, the pharmacological differences between regular- and low-dose aspirin, as well as the potential anti-tumor mechanism of aspirin, supporting a possible therapeutic effect on endometrial cancer. A proposed mechanism behind decreased cancer mortality in endometrial cancer may be a result of inhibition of metastasis via platelet inactivation and possible prostaglandin E 2 suppression by aspirin. Additionally, aspirin use in particular may have a secondary benefit for obesity-related comorbidities including cardiovascular disease in women with endometrial cancer. Although aspirin-related bleeding needs to be considered as a possible adverse effect, the benefits of aspirin therapy may exceed the potential risk in women with endometrial cancer. The current evidence reviewed herein has resulted in conflicting findings regarding the potential effect on endometrial cancer outcomes, thus indicating that future studies in this area are needed to resolve the effects of aspirin on endometrial cancer survival, particularly to identify specific populations that might benefit from aspirin use.

  12. Aspirin dose and ticagrelor benefit in PLATO: fact or fiction?

    Science.gov (United States)

    Serebruany, Victor L

    2010-01-01

    To summarize the available evidence regarding whether or not a higher aspirin maintenance dose inversely affects the ticagrelor benefit observed in the US cohort of the PLATO trial. In the recent PLATO trial, the daily aspirin dosages in the USA were split between 81 and 325 mg while the vast majority of dosing outside of the USA was 75 or 100 mg. The FDA conducted exhaustive analyses of the aspirin dosage in a framework of primary clinical efficacy. Considering the post hoc, not prespecified nature of such analyses as well as multiple confounding problems with biologic plausibility, sensitivity to reclassification of small numbers of cases regarding loading versus maintenance aspirin dosing, and the distribution of events in high-dose aspirin observed outside of the USA, the FDA documents clearly suggest that aspirin dosing does not explain the disparate outcome results. In addition, the Advisory Committee members found no evidence to establish a reasonable link, and they uniformly rejected the hypothesis that aspirin dose affects the heterogeneity of outcomes in PLATO. Additional evidence driven from the FDA review on aspirin dose and PLATO outcomes is reassessed. The wide distribution of outcomes differing from country to country, and inconsistency in European data despite identical aspirin doses, preclude the acceptance of the hypothesis that aspirin affects PLATO outcomes in general or adversely impacts the benefit of ticagrelor in the US cohort in particular. Differences in primary site monitoring by the study sponsor in most countries versus a third-party CRO in the USA represent an alternative explanation and deserve further attention. There is no solid evidence that aspirin dose affects outcomes after ticagrelor. Reevaluation of the overall endpoint differences, especially focusing on mortality, driven from sponsor-monitored sites versus outcomes observed by independent CROs is neccessary. The practice of self-monitoring in pivotal indication

    The importance of lactose malabsorption in irritable bowel syndrome (IBS) is not well defined and these patients often complain of lactose intolerance. To objectively measure lactose malabsorption, a hydrogen breath test (HBT) can be performed, but a discrepancy emerges between the results of the HBT and the symptomatic response during the HBT. To determine in a group of IBS patients whether self-perceived lactose intolerance and the symptomatic response to lactose HBT were conditioned by other factors besides the presence of lactose malabsorption. Oral challenge to lactose (50 g) was tested in 51 IBS patients to assess HBT malabsorption and the symptomatic response to lactose intolerance was scored on a validated questionnaire. Allergological screening for common inhalants and food allergens (including cow's milk) was performed. The presence of psychological factors (e.g. anxiety, depression, fatigue) was evaluated using validated questionnaires. A total of 21 out of 51 patients (41.1%) were self-perceived to be lactose intolerant, 24/51 (47%) had a positive HBT, and 14/51 (27.4%) presented with symptoms of lactose intolerance during HBT. The serological screening for inhalant and food allergens was positive in 6/21 (28.6%) and 4/21 (19%) of patients who self-perceived lactose intolerance and in 5/14 (37.5%) and 3/14 (21.4%) in intolerant patients symptomatic during HBT. Only 1/51 (1.9%) presented evidence of IgE-mediated hypersensitivity to cow's milk. Patients who experienced symptoms of lactose intolerance during HBT presented more severe IBS symptoms [326 (296-398) vs. 215 (126-295) P=0.05] and a higher score of anxiety, depression, and fatigue. Factors influencing the symptoms of lactose intolerance during HBT resulted in an increase in hydrogen produced and in the severity of IBS. In a cohort of 51 IBS patients, the symptoms of lactose intolerance during HBT were influenced by the capacity to absorb lactose and the severity of IBS. Other factors, such as

    Our understanding of asthma has evolved over time from a singular disease to a complex of various phenotypes, with varied natural histories, physiologies, and responses to treatment. Early therapies treated most patients with asthma similarly, with bronchodilators and corticosteroids, but these therapies had varying degrees of success. Similarly, despite initial studies that identified an underlying type 2 inflammation in the airways of patients with asthma, biologic therapies targeted toward these type 2 pathways were unsuccessful in all patients. These observations led to increased interest in phenotyping asthma. Clinical approaches, both biased and later unbiased/statistical approaches to large asthma patient cohorts, identified a variety of patient characteristics, but they also consistently identified the importance of age of onset of disease and the presence of eosinophils in determining clinically relevant phenotypes. These paralleled molecular approaches to phenotyping that developed an understanding that not all patients share a type 2 inflammatory pattern. Using biomarkers to select patients with type 2 inflammation, repeated trials of biologics directed toward type 2 cytokine pathways saw newfound success, confirming the importance of phenotyping in asthma. Further research is needed to clarify additional clinical and molecular phenotypes, validate predictive biomarkers, and identify new areas for possible interventions. PMID:26161792

    Gender differences in asthma incidence, prevalence and severity have been reported worldwide. After puberty, asthma becomes more prevalent and severe in women, and is highest in women with early menarche or with multiple gestations, suggesting a role for sex hormones in asthma genesis. However, the impact of sex hormones on the pathophysiology of asthma is confounded by and difficult to differentiate from age, obesity, atopy, and other gender associated environmental exposures. There are also gender discrepancies in the perception of asthma symptoms. Understanding gender differences in asthma is important to provide effective education and personalized management plans for asthmatics across the lifecourse. PMID:26141573

    Intolerance to various foods, excluding bona fide coeliac disease and lactose intolerance, represents a growing cause of patient visits to allergy clinics.Histamine intolerance is a long-known, multifaceted clinical condition triggered by histamine-rich foods and alcohol and/or by drugs that liberate histamine or block diamine oxidase (DAO), the main enzyme involved in the metabolism of ingested histamine. Histamine limitation diets impose complex, non-standardized restrictions that may severely impact the quality of life of patients. We retrospectively evaluated 14 patients who visited allergy outpatient facilities in northern Italy with a negative diagnosis for IgE-mediated food hypersensitivity, coeliac disease, conditions related to gastric hypersecretion, and systemic nickel hypersensitivity, and who previously underwent a histamine limitation diet with benefits for their main symptoms. Serum diamine oxidase levels and the clinical response to diamine oxidase supplementation were investigated. We found that 10 out of 14 patients had serum DAO activityintolerance. Moreover, 13 out of 14 patients subjectively reported a benefit in at least one of the disturbances related to food intolerances following diamine oxidase supplementation. The mean value (±SD) of diamine oxidase activity in the cohort of patients with histamine intolerance symptoms was 7.04±6.90 U/mL compared to 39.50±18.16 U/mL in 34 healthy controls (P=0.0031). In patients with symptoms triggered by histamine-rich food, measuring the serum diamine oxidase activity can help identify subjects who can benefit from a histamine limitation diet and/or diamine oxidase supplementation.Properly designed, controlled studies investigating histamine intolerance that include histamine provocation are indispensable for providing insights into the area of food intolerances, which are currently primarily managed with non-scientific approaches in Italy. © The Author(s) 2015.

    Fetal intolerance of labor is a common indication for delivery by Caesarean section. Diagnosis is based on the presence of category III fetal heart rate tracing, which is an abnormal heart tracing associated with increased likelihood of fetal hypoxia and metabolic acidemia. This study analyzed data from 177 unique women who, during their prenatal visits (7-15 weeks and/or 24-32 weeks) to Atlanta area prenatal care clinics, consented to provide blood samples for DNA methylation (HumanMethylation450 BeadChip) and gene expression (Human HT-12 v4 Expression BeadChip) analyses. We focused on 57 women aged 18-36 (mean 25.4), who had DNA methylation data available from their second prenatal visit. DNA methylation patterns at CpG sites across the genome were interrogated for associations with fetal intolerance of labor. Four CpG sites (P value intolerance of labor. DNA methylation and gene expression were negatively associated when examined longitudinally during pregnancy using a linear mixed-effects model. Positive predictive values of methylation of these four sites ranged from 0.80 to 0.89, while negative predictive values ranged from 0.91 to 0.92. The four CpG sites were also associated with fetal intolerance of labor in an independent cohort (the Johns Hopkins Prospective PPD cohort). Therefore, fetal intolerance of labor could be accurately predicted from maternal blood samples obtained between 24-32 weeks gestation. Fetal intolerance of labor may be accurately predicted from maternal blood samples obtained between 24-32 weeks gestation by assessing DNA methylation patterns of SLC9B1. The identification of pregnant women at elevated risk for fetal intolerance of labor may allow for the development of targeted treatments or management plans.

    Full Text Available Orthostatic challenge produced by upright posture may lead to syncope if the cardiovascular system is unable to maintain adequate brain perfusion. This review outlines orthostatic intolerance related to the aging process, long-term bedrest confinement, drugs, and disease. Aging-associated illness or injury due to falls often leads to hospitalization. Older patients spend up to 83% of hospital admission lying in bed and thus the consequences of bedrest confinement such as physiological deconditioning, functional decline, and orthostatic intolerance represent a central challenge in the care of the vulnerable older population. This review examines current scientific knowledge regarding orthostatic intolerance and how it comes about and provides a framework for understanding of (patho- physiological concepts of cardiovascular (in- stability in ambulatory and bedrest confined senior citizens as well as in individuals with disease conditions [e.g., orthostatic intolerance in patients with diabetes mellitus, multiple sclerosis, Parkinson's, spinal cord injury (SCI] or those on multiple medications (polypharmacy. Understanding these aspects, along with cardio-postural interactions, is particularly important as blood pressure destabilization leading to orthostatic intolerance affects 3–4% of the general population, and in 4 out of 10 cases the exact cause remains elusive. Reviewed also are countermeasures to orthostatic intolerance such as exercise, water drinking, mental arithmetic, cognitive training, and respiration training in SCI patients. We speculate that optimally applied countermeasures such as mental challenge maintain sympathetic activity, and improve venous return, stroke volume, and consequently, blood pressure during upright standing. Finally, this paper emphasizes the importance of an active life style in old age and why early re-mobilization following bedrest confinement or bedrest is crucial in preventing orthostatic intolerance, falls

    Lactose malabsorption and lactose intolerance symptoms are the most common alimentary tract disorders in children. Lactose intolerance is a result of lactase deficiency or lack of lactase and lactose malabsorption. Hypersensitivity in food allergy is connected with the presence of specific IgE (specific antibodies against some allergens) or lymphocytes. Lactose intolerance and food allergy may coexist in the same patient. The aim of this study was determination of lactose intolerance frequency in children with food allergy who were below and above 5 years of age. The number of 87 children with food allergy aged from 0.7 to 18 years were included in the study (48 boys and 39 girls). 51 patients above 5 years of age and 36 patients below 5 years of age were studied. Lactose intolerance symptoms, hydrogen breath test, activity of lactase and villous atrophy were investigated. Decreased absorption of lactose in hydrogen breath test was observed in 28% of children above 5 years of age and in 5% in younger children. Positive result of biological trial in hydrogen breath test was observed in 10% of patients who were below 5 years of age and in 26% patients above 5 years. There was no statistically significant difference in lactose intolerance frequency and in decreased activity of lactase in intestinal mucosa between these two groups. Frequent partial villous atrophy was observed in younger patients (41,38%) than in children above 5 years of age (17.86%). Lactose intolerance was observed in 10% patients who were below 5 years of age and in 26% patients above 5 years of age with food allergy. There was no statistically significant difference between these two groups.

    The aspirin induced platelet aggregation has been reported to be mediated through the inhibition of platelet prostaglandin synthesis. This compound has also been recently reported to stimulate nitric oxide synthesis in platelets. Since nitric oxide has been reported to produce fibrinogen/fibrinolytic effect, investigation was carried out to determine fibrinolytic effect of in vivo exposure of platelets to aspirin in normal volunteers on the fibrinolysis of the clotted platelet-rich plasma in vitro. The thrombolytic effect of aspirin in situ was also carried out by injecting aspirin solution in the mice with ADP induced formed thrombi in the coronary artery. It was found that the clotted platelet-rich plasma prepared from the volunteers (n = 10, F = 5, M = 5) who ingested 150 mg aspirin, began to undergo spontaneous and progressive fibrinolysis for 200 min at 37 degrees C with the generation of fibrin degradation products in the lysate. No such fibrinolysis could be seen in control experiments. When platelet thrombi were produced in the coronary artery of mice by injecting ADP, and these animals subsequently received intravenous injection of aspirin (4 muM final), they not only survived (P < 0.0001, n = 10) the thrombogenic assault but the lysis of the platelet thrombi was also noted in the post mortem examination. The thrombolytic effect of aspirin was found to be comparable to that of streptokinase in these animals. Aspirin, through the stimulation of NO synthesis, may produce thrombolysis in vivo.

  10. Aspirin and lipid mediators in the cardiovascular system.

    Schrör, Karsten; Rauch, Bernhard H

    2015-09-01

    Aspirin is an unique compound because it bears two active moieties within one and the same molecule: a reactive acetyl group and the salicylate metabolite. Salicylate has some effects similar to aspirin, however only at higher concentrations, usually in the millimolar range, which are not obtained at conventional antiplatelet aspirin doses of 100-300 mg/day. Pharmacological actions of aspirin in the cardiovascular system at these doses are largely if not entirely due to target structure acetylation. Several classes of lipid mediators become affected: Best known is the cyclooxygenase-1 (COX-1) in platelets with subsequent inhibition of thromboxane and, possibly, thrombin formation. By this action, aspirin also inhibits paracrine thromboxane functions on other lipid mediators, such as the platelet storage product sphingosine-1-phosphate (S1P), an inflammatory mediator. Acetylation of COX-2 allows for generation of 15-(R)HETE and subsequent formation of "aspirin-triggered lipoxin" (ATL) by interaction with white cell lipoxygenases. In the cardiovascular system, aspirin also acetylates eNOS with subsequent upregulation of NO formation and enhanced expression of the antioxidans heme-oxygenase-1. This action is possibly also COX-2/ATL mediated. Many more acetylation targets have been identified in live cells by quantitative acid-cleavable activity-based protein profiling and might result in discovery of even more aspirin targets in the near future.

However, despite this evidence, underutilization of aspirin in eligible women is reported. In women of reproductive age, it may also have a role to play in reducing early-onset preeclampsia and intrauterine growth restriction, and in the prevention of recurrent miscarriage in women with antiphospholipid antibodies; it may also reduce cardiovascular risk in associated systemic conditions such as lupus. Aspirin may reduce colorectal cancer risk in women, but its role in breast cancer warrants further data from controlled trials.Conclusions: The risk–benefit threshold for aspirin use in women has been established for several conditions.

    People with asthma may show less tolerance to exercise due to worsening asthma symptoms during exercise or other reasons such as deconditioning as a consequence of inactivity. Some may restrict activities as per medical advice or family influence and this might result in reduced physical fitness. Physical training programs aim to improve physical fitness, neuromuscular coordination and self confidence. Subjectively, many people with asthma report that they are symptomatically better when fit, but results from trials have varied and have been difficult to compare because of different designs and training protocols. Also, as exercise can induce asthma, the safety of exercise programmes needs to be considered. To gain a better understanding of the effect of physical training on the respiratory and general health of people with asthma, from randomised trials. We searched the Cochrane Airways Group Specialised Register of trials up to January 2013. We included randomised trials of people over eight years of age with asthma who were randomised to undertake physical training or not. Physical training had to be undertaken for at least 20 minutes, two times a week, over a minimum period of four weeks. Two review authors independently assessed eligibility for inclusion and undertook risk of bias assessment for the included studies. Twenty-one studies (772 participants) were included in this review with two additional 2012 studies identified as 'awaiting classification'. Physical training was well tolerated with no adverse effects reported. None of the studies mentioned worsening of asthma symptoms following physical training. Physical training showed marked improvement in cardiopulmonary fitness as measured by a statistically and clinically significant increase in maximum oxygen uptake (mean difference (MD) 4.92 mL/kg/min; 95% confidence interval (CI) 3.98 to 5.87; P physical training may have positive effects on health-related quality of life, with four of five studies

    Full Text Available Introduction: inflammation has been shown to play a major role in the pathogenesis of cancer. Inflammatory process activates the immune system through pro-inflammatory mediators and subsequent triggers transformation into malignant cells. Some tumors or cancers has been associated with chronic infections, such as hepatitis B and C viruses (hepatocellular carcinoma, human papilloma virus (cervical cancer, Helicobacter pylori (gastric cancer and lymphoma, and prostatitis (prostate cancer. A considerable study have investigated the benefits of aspirin for the prevention and treatment of cancer or tumors. Objectives: This paper aims to describe the relationship between inflammation and cancer incidence, so that use of aspirin as an anti-inflammatory agent is a rational choice in the treatment and prevention of cancer. Conclusion: Aspirin potential for chemoprevention of various types of cancer. Considering the high risk of side effects of aspirin, aspirin is not intended as a routine therapy to prevent the occurrence of cancer.

    The influence of a single dose of aspirin (5.4-7.4 mg/kg) on platelet uptake on 4-mm Dacron interposition grafts was studied in a baboon model using gamma camera scanning for 111-Indium labeled platelets. In vitro assessment of platelet function after aspirin administration revealed that in the baboon, as in the human, aspirin abolished arachidonic acid-induced platelet aggregation, prolonged the lag time between exposure to collagen and aggregation, and decreased plasma thromboxane B2 levels. Aspirin also prolonged the template bleeding time. Scans for 111-Indium labeled platelets revealed that pretreatment with a single dose of aspirin decreased platelet uptake on 4-mm Dacron carotid interposition grafts. This decrease in platelet uptake was associated with a significant improvement in 2-hour graft patency and with a trend toward improved 2-week patency.

  3. Is aspirin a cause of Reye's syndrome? A case against.

    2002-01-01

    Reye's syndrome was a rare disease which appeared suddenly in the early 1950s and disappeared just as suddenly in the late 1980s. An association between Reye's syndrome and the ingestion of aspirin (acetylsalicylic acid) was claimed, although no proof of causation was ever established. The presence of salicylates in the blood or urine of Reye's syndrome patients has not been demonstrated, and no animal model of Reye's syndrome has been developed where aspirin causes the disease. It is clear from epidemiological data that the incidence of Reye's syndrome was decreasing well before warning labels were placed on aspirin products. Reye's syndrome disappeared from countries where aspirin was not used in children as well as from countries which continued to use aspirin in children. Reye's syndrome was probably either a viral mutation which spontaneously disappeared, or a conglomeration of metabolic disorders that had not been recognized or described at that time.

  4. Willow species and aspirin: different mechanism of actions.

    2011-07-01

    Many believe that willow is the natural source of aspirin. However, willow species contain only a low quantity of the prodrug salicin which is metabolized during absorption into various salicylate derivatives. If calculated as salicylic acid, the daily salicin dose is insufficient to produce analgesia. Salicylic acid concentrations following an analgesic dose of aspirin are an order of magnitude higher. Flavonoids and polyphenols contribute to the potent willow bark analgesic and anti-inflammatory effect. The multi-component active principle of willow bark provides a broader mechanism of action than aspirin and is devoid of serious adverse events. In contrast to synthetic aspirin, willow bark does not damage the gastrointestinal mucosa. An extract dose with 240 mg salicin had no major impact on blood clotting. In patients with known aspirin allergy willow bark products are contraindicated. Copyright © 2011 John Wiley & Sons, Ltd.

    Clinical evidences and epidemiological studies show that allergic pathologies of the respiratory tract are increasing in the world areas with high pollution impact, demonstrating how many polluting substances favor both allergic sensitization and the bronchial inflammatory changes characteristic of asthma. It has been shown that asthma, as many other diseases, is a complex interaction between genetic predisposition and environmental stimuli that results in clinical expression of various phenotypes of asthma: allergic, intrinsic etc. Many pollutants have such a potential. Diesel exhaust particles (DEP) can favor allergic sensitization, induce acute asthma attacks and increase bronchial reactivity, acting both on allergen, on bronchial mucosa and on immune cells. In fact, DEP can favor B lymphocytes to shift to a production of IgE and T cells to produce Th2 cytokines. Asthma can be also induced by high exposure to many other substances as NO2 and first of all ozone (O3): strong oxidizing substance that is synthesized, in absence of ventilation, by photochemical reaction due to the combination of ultraviolet sun radiation on exhaust gases as NO2 and hydrocarbons. Ozone is abundant in cities with minimal concentration in the morning gradually increasing during the day until maximal levels in the afternoon and then decreasing during the night. Epidemiological studies show that the number of access to hospital for acute asthma and even the use of bronchodilator by asthmatics increase during the high level periods when Ozone constitute almost 90 percent of the total oxidants in the environment. Particulate matter of very small diameter have a crucial role in favoring asthma attacks, and smaller the substance deeper the penetration in the bronchial tree, with an inflammatory reaction in the peripheral bronchial mucosa characterized by increased vessel permeability, mucosal edema, inflammatory mediator production by damaged epithelium and inflammatory cells that determines

    To find out the diet measurements for alleviating symptoms of lactose intolerance when people had had a drink of milk. Eight lactose intolerance (LI) subjects suffering from watery diarrhea were selected from 38 subjects by using hydrogen breath test (HBT) joined the test of drinking cow's milk along with various other foods designed by orthogonal trial. The 100 healthy college students were selected to observe symptoms after they ingested 25 g milk powder in different manners. The breath-hydrogen concentration in groups with ingesting milk and various other foods was lower than those with ingesting milk only. Egg was better than mantou in alleviating symptoms. (F vaule of stool lactose and symptom score were 7.5, 9.0, respectively, P college students by drinking milk in fasting state (27/98) was significant in comparing with those drinking milk in regular meal (13/98), chi2 = 6. 156, P food, and different milk drinking manners should affect the intolerance symptoms. We suggested: should not drink milk in fasting state, and drinking milk together with egg and staple food such as steamed bread, bread or gomuti should be the best choice for breakfast. Drinking milk with regular manner might alleviate the symptoms of intolerance. For avoiding lactose intolerance, whole wheat bread should not be taken along with milk.

    The purpose was to study the prevalence of environmental intolerance (EI) and its different manifestations, including behavioral changes and disability. Fertile-aged women ( n = 680) of the Kuopio Birth Cohort Study were asked about annoyance to 12 environmental factors, symptoms and behavioral changes. We asked how much the intolerance had disrupted their work, household responsibilities or social life. We chose intolerance attributed to chemicals, indoor molds, and electromagnetic fields to represent typical intolerance entities. Of the respondents, 46% reported annoyance to chemicals, molds, or electromagnetic fields. Thirty-three percent reported symptoms relating to at least one of these three EIs, 18% reported symptoms that included central nervous system symptoms, and 15% reported behavioral changes. Indicating disability, 8.4% reported their experience relating to any of the three EIs as at least "somewhat difficult", 2.2% "very difficult" or "extremely difficult", and 0.9% "extremely difficult". Of the latter 2.2%, all attributed their intolerance to indoor molds, and two thirds also to chemicals. As the number of difficulties increased, the number of organ systems, behavioral changes and overlaps of the three EIs also grew. EI is a heterogeneous phenomenon and its prevalence depends on its definition. The manifestations of EI form a continuum, ranging from annoyance to severe disability.

    Salicylates intolerance is related to alteration in the metabolism of arachidonic acid leading to increased leukotrienes. The condition may be manifested with respiratory, skin or systemic symptoms or associated with sinonasal polyposis. Salicylates are present in anti-inflammatory drugs, cosmetics products and food. To determine the prevalence of salicylates intolerance in patients with sinonasal polyposis presenting to Clinical Immunology and Allergy and Otolaryngology Service, CMN 20 Noviembre, Mexico City. An observational, descriptive, cross sectional study included patients with sinonasal polyposis. The sample size was 49 patients, and variables were compared using STATISTICA 8.0. The prevalence of sinonasal polyposis was 4% of the study group, predominantly in females; only 24% of the population had an ideal weight, the salicylates intolerance prevalence was 53%, and the Samter triad was 31%. Sinonasal polyposis has an inflammatory disease pattern. Its pathophysiology is not yet fully established and in this study was related to obesity and persistent sinusitis. The most feared complication recurrence is associated with salicylates intolerance. The study found a slight increase of recurrence in the group of intolerance, with no statistically significant difference, possibly related to the sample size.

    Aspirin and other non-steroidal anti-inflammatory drugs have a high affinity for phospholipid membranes, altering their structure and biophysical properties. Aspirin has been shown to partition into the lipid head groups, thereby increasing membrane fluidity. Cholesterol is another well known mediator of membrane fluidity, in turn increasing membrane stiffness. As well, cholesterol is believed to distribute unevenly within lipid membranes leading to the formation of lipid rafts or plaques. In many studies, aspirin has increased positive outcomes for patients with high cholesterol. We are interested if these effects may be, at least partially, the result of a non-specific interaction between aspirin and cholesterol in lipid membranes. We have studied the effect of aspirin on the organization of 1,2-dipalmitoyl-sn-glycero-3-phosphatidylcholine (DPPC) membranes containing cholesterol. Through Langmuir-Blodgett experiments we show that aspirin increases the area per lipid and decreases compressibility at 32.5 mol% cholesterol, leading to a significant increase of fluidity of the membranes. Differential scanning calorimetry provides evidence for the formation of meta-stable structures in the presence of aspirin. The molecular organization of lipids, cholesterol and aspirin was studied using neutron diffraction. While the formation of rafts has been reported in binary DPPC/cholesterol membranes, aspirin was found to locally disrupt membrane organization and lead to the frustration of raft formation. Our results suggest that aspirin is able to directly oppose the formation of cholesterol structures through non-specific interactions with lipid membranes. Copyright © 2014 Elsevier B.V.

    Considerable evidence supports the effectiveness of aspirin for chemoprevention of colorectal cancer (CRC) in addition to its well-established benefits in the prevention of vascular disease. Epidemiologic studies have consistently observed an inverse association between aspirin use and risk of CRC. A recent pooled analysis of a long-term post-trial follow-up of nearly 14,000 patients from 4 randomized, cardiovascular disease prevention trials showed that daily aspirin treatment for about 5 years was associated with a 34% reduction in 20-year CRC mortality. A separate meta-analysis of nearly 3,000 patients with a history of colorectal adenoma or cancer in 4 randomized adenoma prevention trials demonstrated that aspirin reduced the occurrence of advanced adenomas by 28% and any adenoma by 17%. Aspirin has also been shown to be beneficial in a clinical trial of patients with Lynch syndrome, a hereditary CRC syndrome; in those treated with aspirin for at least 2 years, there was a ≥ 50% reduction in the risk of CRC commencing 5 years after randomization and after aspirin had been discontinued. A few observational studies have shown an increase in survival among patients with CRC who use aspirin. Taken together, these findings strengthen the case for consideration of long-term aspirin use in CRC prevention. Despite these compelling data, there is a lack of consensus about the balance of risks and benefits associated with long-term aspirin use, particularly in low-risk populations. The optimal dose to use for cancer prevention and the precise mechanism underlying aspirin’s anticancer effect require further investigation. PMID:22084361

    We have recently shown that dipyrone (metamizole), a non-opioid analgesic, can nullify aspirin (acetylsalicylic acid; ASA) antiplatelet effects in patients with coronary artery disease (CAD). In this study, we analysed the aspirin and dipyrone drug-drug interaction in order to identify strategies to prevent the dipyrone induced inhibition of asprin antiplatelet effects. Platelet function was measured by arachidonic acid-induced light-transmission aggregometry, thromboxane (TX) B2- formation by immunoassay. Dipyrone metabolite plasma levels were determined by high-performance-liquid-chromatography (HPLC). In seven healthy individuals, in vitro ASA (30 µM/ 100 µM/ 300 µM/ 1,000 µM) and dipyrone (10 µM) coincubation revealed, that the aspirin and dipyrone interaction can be overcome by increasing doses of aspirin. In 36 aspirin and dipyrone comedicated CAD patients, addition of ASA (30 µM/ 100 µM) in vitro inhibited, but did not completely overcome the dipyrone induced reduction of aspirin antiplatelet effects. Notably, the inhibition of thromboxane formation in aspirin and dipyrone comedicated CAD patients coincided with dipyrone plasma levels. In a cross-over designed study in four healthy individuals, we were able to prove that inhibition of aspirin (100 mg/ day) effects by dipyrone (750 mg/ day) was reversible. Furthermore, aspirin (100 mg/ day) medication prior to dipyrone (750 mg/ day) intake prevented the inhibition of antiplatelet effects by dipyrone in 12 healthy individuals. In conclusion, aspirin medication prior to dipyrone intake preserves antiplatelet effects, circumventing the pharmacodynamic drug-drug interaction at the level of cyclooxygenase-1.

    The objective of this study was to develop poly (d,l-lactide-co-glycolide) (PLGA) based injectable phase sensitive in situ gel forming delivery system for controlled delivery of aspirin, and to characterize the effect of drug/polymer interaction on the in vitro release of aspirin and polymer degradation. Aspirin was dissolved into PLGA solution in 1-methyl-2-pyrrolidone. Poly(ethylene glycol)400 was used as plasticizer to reduce initial burst release. The solution formulation was injected into aqueous release medium to form a gel depot. Released samples were withdrawn periodically and assayed for aspirin content by high performance liquid chromatography. The effect of aspirin on the degradation of PLGA matrix was evaluated using Proton Nuclear Magnetic Resonance and Gel Permeation Chromatography. PLGA based in situ gel forming formulations controlled the in vitro release of aspirin for 7 days only. Analysis of PLGA matrix residuals revealed that PLGA in aspirin loaded formulations exhibited a significantly (pdegradation compared to blank formulations. These findings suggest that aspirin causes an unusually faster degradation of PLGA. Such faster degradation of PLGA has not been noticed for any other drugs reported in the literature.

    specialized outpatient clinic. A systematic protocol for patient evaluation and follow-up was applied. Treatment compliance and control of the disease at the end of follow-up were defined by clinical and functional data. Patients who did not meet asthma control criteria after six months despite compliance with treatment and correct use of medication were characterized as treatment-resistant. Phenotypes were determined by factorial analysis and compared using various tests. RESULTS: At the end of follow-up, 88 patients were considered treatment compliant and 23 were considered noncompliant. Factorial analysis of the compliant patients identified four phenotypes: phenotype 1 (28 patients comprised patients who were treatment-resistant, more often presenting nocturnal symptoms and exacerbations, as well as more often using rescue bronchodilators; phenotype 2 (48 patients comprised patients with persistent airflow limitation, lower ratios of forced expiratory volume in one second/forced vital capacity at baseline, more advanced age and longer duration of symptoms; phenotype 3 (42 patients comprised patients with allergic rhinosinusitis who were nonsmokers and presented predominantly reversible airflow obstruction; and phenotype 4 (15 patients comprised cases with a history of aspirin intolerance to acetylsalicylic acid associated with near-fatal asthma. Conclusions: A significant number of patients with severe asthma are noncompliant with treatment. Although many patients with severe asthma have persistent airflow obstruction, the most relevant clinical phenotype comprises patients who are resistant to the typical treatment.

    Asthma is a complex and heterogeneous disease with several phenotypes, including an allergic asthma phenotype characterized by TH2 cytokine production and associated with allergen sensitization and adaptive immunity. Asthma also includes nonallergic asthma phenotypes, such as asthma associated with exposure to air pollution, infection, or obesity, that require innate rather than adaptive immunity. These innate pathways that lead to asthma involve macrophages, neutrophils, natural killer T cells, and innate lymphoid cells, newly described cell types that produce a variety of cytokines, including IL-5 and IL-13. We review the recent data regarding innate lymphoid cells and their role in asthma. Copyright © 2014 American Academy of Allergy, Asthma & Immunology. Published by Mosby, Inc. All rights reserved.

  19. Comparative effect of clopidogrel and aspirin versus aspirin alone on laboratory parameters: a retrospective, observational, cohort study

    Science.gov (United States)

    2013-01-01

    Background Clopidogrel and aspirin are antiplatelet agents that are recommended to reduce the risk of recurrent stroke and other cardiovascular events. Combination therapy of clopidogrel and aspirin has been shown to increase the risk of hemorrhage, but the effects of the drugs on laboratory parameters have not been well studied in patients in routine clinical practice. Therefore, we evaluated and compared the effects of combination therapy with clopidogrel plus aspirin and aspirin monotherapy on laboratory parameters using a clinical database. Methods We used data from the Clinical Data Warehouse of Nihon University School of Medicine obtained between November 2004 and April 2011, to identify cohorts of new users (n = 159) of clopidogrel (75 mg/day) plus aspirin (100 mg/day) and new users (n = 834) of aspirin alone (100 mg/day). We used a multivariable regression model and regression adjustment with the propensity score to adjust for differences in baseline covariates between settings, and compare the mean changes in serum levels of creatinine, aspartate aminotransferase, alanine aminotransferase and hematological parameters, including hemoglobin level, hematocrit, and white blood cell (WBC), red blood cell and platelet counts up to two months after the start of study drug administration. Results After adjustment, the reduction of WBC count in clopidogrel plus aspirin users was significantly greater than that in aspirin alone users. All other tests showed no statistically significant difference in the mean change from baseline to during the exposure period between clopidogrel plus aspirin users and aspirin alone users. The combination of clopidogrel and aspirin increased the risk of gastrointestinal bleeding compared with aspirin alone, with a relative risk ranging from 2.06 (95% CI, 1.02 to 4.13; p = 0.043) for the multivariate model and 2.61 (95% CI, 1.18 to 5.80; p = 0.0184) for propensity adjustment. Conclusion Our findings suggested that

    There are limited data on aspirin (ASA) desensitization for patients with coronary artery disease. The aim of the present study was to assess the safety and efficacy of a standard rapid desensitization protocol in patients with ASA sensitivity undergoing coronary angiography. This is a prospective, multicenter, observational study including 7 Italian centers including patients with a history of ASA sensitivity undergoing coronary angiography with intent to undergo percutaneous coronary intervention. A total of 330 patients with history of ASA sensitivity with known/suspected stable coronary artery disease or presenting with an acute coronary syndrome, including ST-segment-elevation myocardial infarction were enrolled. Adverse effects to aspirin included urticaria (n=177, 53.6%), angioedema (n=69, 20.9%), asthma (n=65, 19.7%), and anaphylactic reaction (n=19, 5.8%). Among patients with urticaria/angioedema, 13 patients (3.9%) had a history of idiopathic chronic urticaria. All patients underwent a rapid ASA (5.5 hours) desensitization procedure. The desensitization procedure was performed before cardiac catheterization in all patients, except for those (n=78, 23.6%) presenting with ST-segment-elevation myocardial infarction who underwent the desensitization after primary percutaneous coronary intervention. Percutaneous coronary intervention was performed in 235 patients (71%) of the overall study population. The desensitization procedure was successful in 315 patients (95.4%) and in all patients with a history of anaphylactic reaction. Among the 15 patients (4.6%) who did not successfully respond to the desensitization protocol, adverse reactions were minor and responded to treatment with corticosteroids and antihistamines. Among patients with successful in-hospital ASA desensitization, 253 patients (80.3%) continued ASA for at least 12 months. Discontinuation of ASA in the 62 patients (19.7%) who had responded to the desensitization protocol was because of medical

    To explore asthma pathogenesis using data from upper and lower airways. English-language papers on human asthma and nasal polyp subjects from 1990 onwards. High-quality studies in established journals. The recognition of its inflammatory nature led to a quantum leap in the understanding and treatment of asthma, with lives saved by inhaled corticosteroids. Further work at genetic, molecular, histological and clinical levels has shown that asthma is polymorphic and rarely involves isolated Th2 bronchial inflammation. Viral infections may act as an initiating event in children and adults, showing synergy with atopy. Chronic staphylococcal colonization of the mucosa may act as a promoter, as in atopic dermatitis. These two observations may be linked, with viruses providing an entry for bacteria into the mucosal epithelium. Most asthma begins in the nose and involves allergy and infection: both viral and bacterial. The combination of atopy and infection suggests new possibilities for therapy. © 2014 The Author.

    Medline, government reports and conference proceedings were searched. Case-control, cohort or cross sectional studies were included if they provided relevant and applicable quantitative information on the relation between asthma and caries, had an independent study population and adequate definitions of asthma and caries and appropriate measurement of caries. Data were extracted independently by two reviewers and quality was assessed using the Newcastle-Ottawa Quality Assessment Scale. Fixed- and random-effects models were used for the analyses. Heterogeneity and publication bias were evaluated. Eighteen articles were included; 11 provided information on primary dentition and 15 on permanent dentition. Random-effects models showed a significant association between asthma and caries for both primary and permanent dentition, the odds ratios being 2.73 (95% CI: 1.61, 4.64) and 2.04 (95% CI: 1.44, 2.89), respectively. Evidence from this analysis suggests that asthma doubles the risk of caries in both primary and permanent dentition. Publication bias diagnostics and simulation suggested possible overestimation of the summary odds ratio for permanent dentition but not for primary dentition. Physicians and dentists should recommend preventive measures against caries for people with asthma.

    Asthma is a chronic inflammatory disease of the respiratory tract with a complex genetic background influenced by the exposition to a series of environmental factors. Genetic studies can only elucidate part of the heritability and susceptibility of asthma and even though several diseases have an evident genetic etiology, only a fraction of the genes involved in their pathogenicity have been identified. The epigenetic regulation of the latter is a fact one should bear in mind in order to explain the major triggers of diseases whose understanding is complicated, such as allergies and asthma. External stimulus such as nourishment, stress, physical activity, atmospheric pollution, tobacco smoking and alcohol drinking can induce either gene silencing or gene expression. In this regard, epigenetics can explain how these environmental factors influence our genetic inheritance. There is growing evidence that backs-up the fact that DNA methylation, histone post-translational modification and microRNA expression are influenced by the environment. This helps explaining how several of the risk factors mentioned contribute to the development and inheritance of asthma. In this review, different environmental factors and their relation with the main epigenetic regulatory mechanisms will be analyzed, as well as their possible role in the development of asthma.

    Leidiane Adriano Pereira

    Full Text Available Abstract The authors report a case of unilateral floppy eyelid syndrome with ipsilateral intolerance to brimonidine in a 65-year-old man. The singularity of this case is the combination of two rare illnesses of great phlogistic potentiality in the same eye. The purpose of this article is to report a case of unilateral floppy eyelid syndrome with ipsilateral intolerance to brimonidine, emphasizing a possible relation between them. The result was a unilateral keratopathy that emulated an intraepithelial neoplasia. The key to solving the problem was an unexplained anterior uveitis that raised the suspicion of drug toxicity.The upper eyelid eversion of the affected eye during sleep seemed to be the common denominator of both ailments. The bizarre aspect of the epitheliopathy most likely resulted from the combination of trauma, insufficient lubrication, and drug intolerance.

    Full Text Available In this article, I analyze the roots of intolerance from a psychoanalytic perspective, as well as the ways it has been taken in our politic life in the last years. At first, I expose a relation between intolerance and the Ego origin; in order to understand what changes in the measure of what is or isn’t tolerable in distinct contexts. After that, I analyze the psychosocial conditions for the tolerance of the Other, sustaining that a failure in the symbolic intermediation is an important issue in the contemporary forms of intolerance. From that failure, the relation with ideas and persons remains on an imaginary level, and the reflection ability in inhibited, as it is in a fetish. My conclusion is that a symbolic intermediation between the Ego and the other is a condition to a tolerant coexistence.

    Until recently gluten intolerance has been believed to be typical of celiac disease (CD) and wheat allergy (WA). In the last few years, however, several study results have been published that have proved that gluten intolerance can also affect people who do not suffer from any of the above mentioned diseases. The new syndrome has been named non-celiac gluten sensitivity (NCGS) or gluten sensitivity (GS). It has been included in the new list of gluten-related disorders published in 2012. Researchers believe that NCGS is the most common syndrome of gluten intolerance. This review discusses many aspects of NCGS epidemiology, pathophysiology, clinical spectrum, and treatment and current tools to identify patients suffering from CD, WA, and NCGS.

    To study coping strategies, social support and responsibility for improvement in chemical intolerance (CI). Limited knowledge of CI among health professionals and lay persons places demands on the chemically intolerant individual's coping strategies and perception of social support and ability to take responsibility for improvement. However, there is sparse literature on these issues in CI. A cross-sectional, questionnaire-based, quasi-experimental study. Fifty-nine persons with mild, 92 with moderate and 31 with severe CI participated by rating (i) usage and effectiveness of six problem- and six emotion-focused coping strategies, (ii) emotional, instrumental and informative support provided by various sources and (iii) society's and the inflicted individual's responsibility for improvement. The participants reported that the most commonly used and effective coping strategies were avoiding odorous/pungent environments and asking persons to limit their use of odorous/pungent substances (problem-focused strategies) as well as accepting the situation and reprioritising (emotion-focused strategies). High intolerance severity was associated with problem-focused coping strategies and relatively low intolerance with emotion-focused strategies. More emotional than instrumental and informative support was perceived, predominantly from the partner and other family members. Responsibility attributed to society was also found to increase from mild to moderate/severe intolerance. Certain coping strategies are more commonly used and perceived as more effective than others in CI. However, intolerance severity plays a role regarding both coping strategies and responsibility. Emotional support appears to be the most available type of support. For improved care, certain coping strategies may be suggested by nurses, the healthcare system needs to provide better social support to these patients and the issue of responsibility for improvement may be discussed with the patient.

  15. Statin-associated muscle symptoms-Managing the highly intolerant.

    Science.gov (United States)

    Backes, James M; Ruisinger, Janelle F; Gibson, Cheryl A; Moriarty, Patrick M

    Musculoskeletal symptoms are the most commonly reported adverse effects associated with statin therapy. Yet, certain data indicate that these symptoms often present in populations with underlying musculoskeletal complaints and are not likely statin related. Switching statins or using lower doses resolves muscle complaints in most patients. However, there is a growing population of individuals who experience intolerable musculoskeletal symptoms with multiple statins, regardless of the individual agent or prescribed dose. Recent randomized, placebo-controlled trials enrolling highly intolerant subjects provide significant insight regarding statin-associated muscle symptoms (SAMS). Notable findings include the inconsistency with reproducing muscle complaints, as approximately 40% of subjects report SAMS when taking a statin but not while receiving placebo, but a substantial cohort reports intolerable muscle symptoms with placebo but none when on a statin. These data validate SAMS for those likely experiencing true intolerance, but for others, suggest a psychosomatic component or misattribution of the source of pain and highlights the importance of differentiating from the musculoskeletal symptoms caused by concomitant factors. Managing the highly intolerant requires candid patient counseling, shared decision-making, eliminating contributing factors, careful clinical assessment and the use of a myalgia index score, and isolating potential muscle-related adverse events by gradually reintroducing drug therapy with the utilization of intermittent dosing of lipid-altering agents. We provide a review of recent data and therapeutic guidance involving a focused step-by-step approach for managing SAMS among the highly intolerant. Such strategies usually allow for clinically meaningful reductions in low-density lipoprotein cholesterol and an overall lowering of cardiovascular risk. Copyright © 2017 National Lipid Association.

    Responses to the questionnaire on the diagnosis, patient education and management of asthma indicated that a reduced number of patients with severe asthma were seen in 1993 in both Pediatric and Internal Medicine Departments compared with 5 years before, despite the increase in total number of asthma patients in Japan. Specifiic IgE radioallergosorbent test (RAST measurements were frequently performed instead of skin testing for diagnosis, and eosinophil count and bronchodilator response served as an adjunct to the diagnosis. Patients were frequently asked detailed questions about aspirin-induced asthma, which accounted for 8.8, 2.2 and 1.5% of patients with asthma in the adult, schoolchildren (6–16 years and infant (≤ 5 years groups, respectively. In achieving ‘control of asthma’, first priority was given to coping with the symptoms in children aged 5 years or less and to enabling routine daily life activities in patients 6 years of age or older. Usefulness of peak flow measurements was widely recognized and a detailed plan for allergen avoidance (house dust was often given to patients.

  17. Drug treatment of asthma in the 1990s: achievements and new strategies.

    Science.gov (United States)

    Tavakkoli, A; Rees, P J

    1999-01-01

    Asthma is an inflammatory condition of the airways. First-line therapy involves the use of inhaled corticosteroids as anti-inflammatory agents to control the underlying process. Bronchodilators are used for symptom relief. Short-acting beta-agonists provide rapid relief of bronchoconstriction, whereas long-acting beta-agonists control the symptoms and reduce the frequency of exacerbations when combined with inhaled corticosteroids. Anticholinergic bronchodilators have a minor role in acute exacerbations and in patients troubled by adverse effects from beta-agonists. Theophylline has a bronchodilator action in asthma, but its role as an anti-inflammatory agent needs to be examined further. Because of their toxicity, corticosteroid-sparing agents have a limited role, being restricted to patients with severe uncontrolled asthma. New selective phosphodiesterase IV inhibitors show both anti-inflammatory and bronchodilator characteristics with fewer adverse effects. Other new approaches to the control of inflammation come from the antileukotriene drugs, which improve pulmonary function in patients with chronic asthma. The antileukotrienes have shown promising results, especially in the treatment of asthma caused by aspirin (acetylsalicylic acid), exercise and cold air. Other new therapies being studied include anti-immunoglobulin E, antitryptase and anti-CD4 agents. These newer possibilities suggest that the range of available treatment options will expand significantly over the next decade.

    In routine medical practice, the diagnosis of aspirin hypersensitivity (AH) remains difficult. No clinical feature or biomarker is available to reliably confirm this diagnosis and oral provocation tests (OPT) are rarely performed. To compare asthmatics with and without AH. The clinical characteristics of 21 asthmatics with and 24 without AH respectively were determined. AH was defined by a positive OPT. A full blood count was done before and 24 hours after the OPT. The medical history was associated with a weak sensitivity (52%) and a good specificity (96%) for assessing the diagnosis of AH. There was a higher prevalence of AH in women, and a higher frequency of allergic rhinitis in AH, but no characteristic was useful to facilitate the diagnosis of AH in asthmatic patients. Our results demonstrate higher values of platelets in AH patients. Following OPT, in AH patients only, a decrease in blood eosinophils and an increase in neutrophils was observed. These results confirm that the diagnosis of AH is challenging, with the history having only weak sensitivity. The observation that fluctuations in eosinophils and neutrophils occur following OPT in AH patients only warrants further investigations and suggests a rapid pro-inflammatory role for aspirin.

  19. Lipoxin and Aspirin-Triggered Lipoxins

    Directory of Open Access Journals (Sweden)

    Mario Romano

    2010-01-01

    Full Text Available Lipoxins and their 15 epimers, aspirin triggered lipoxins (ATL, are eicosanoids derived from sequential lipoxygenase (LO metabolism of arachidonic acid. The main routes of lipoxin biosynthesis involve cooperation between 15- and 5-LO, and between 12- and 5-LO. ATL are generated by interactions between 5-LO and aspirin-acetylated cyclooxygenase-2. Cellular models recapitulating these interactions involve leukocytes, platelets, vascular endothelium, and epithelium. To circumvent rapid lipoxin and ATL metabolism and inactivation, stable analogs, bearing potent and long-lasting biological activity, have been synthesized. Some of these analogs displayed therapeutic potential by showing strong anti-inflammatory activity in a number of animal models of disease, including reperfusion injury; arthritis; gastrointestinal, renal, respiratory, and vascular inflammatory disorders; eye damage; periodontitis; and selected infectious diseases. Counter-regulatory signaling by lipoxin A4 and 15-epi-lipoxin A4 is triggered by the activation of a seven-transmembrane domain receptor, termed FPR2/ALX, which is highly expressed in myeloid cells and has been recognized as a main anti-inflammatory receptor.

  20. Flavonoids and Asthma

    2013-01-01

    Asthma is a chronic disease, characterized by airway inflammation, airflow limitation, hyper-reactivity and airway remodeling. It is believed that asthma is caused by the interaction between genetic and environmental factors. The prevalence of allergic diseases, including asthma, has increased worldwide during the past two decades. Although the precise reasons that have caused this increase remain unknown, dietary change is thought to be one of the environmental factors. Flavonoids, which are polyphenolic plant secondary metabolites ubiquitously present in vegetables, fruits and beverages, possess antioxidant and anti-allergic traits, as well as immune-modulating activities. Flavonoids are powerful antioxidants and anti-allergic nutrients that inhibit the release of chemical mediators, synthesis of Th2 type cytokines, such as interleukin (IL)-4 and IL-13, and CD40 ligand expression by high-affinity immunoglobulin E (IgE) receptor-expressing cells, such as mast cells and basophils. They also inhibit IL-4-induced signal transduction and affect the differentiation of naïve CD4+ T cells into effector T-cells through their inhibitory effect on the activation of the aryl hydrocarbon receptor. Various studies of flavonoids in asthmatic animal models have demonstrated their beneficial effects. The results of several epidemiological studies suggest that an increase in flavonoid intake is beneficial for asthma. Moreover, clinical trials of flavonoids have shown their ameliorative effects on symptoms related to asthma. However, these human studies are currently limited; further validation is required to clarify whether an appropriate intake of flavonoids may constitute dietary treatment and for part of a preventive strategy for asthma.

    2014-08-01

    Beta-lactam intolerance, most of which is not IgE or even immunologically mediated even though it is commonly called an "allergy," can be safely managed using the following seven steps: 1. Avoid testing, re-challenging, or desensitizing individuals with histories of beta-lactam associated toxic epidermal necrolysis, Stevens-Johnson syndrome, drug reaction with eosinophilia and systemic symptoms syndrome, severe hepatitis, interstitial nephritis, or hemolytic anemia. 2. Avoid unnecessary antibiotic use, especially in the setting of viral infections. 3. Expect new intolerances to be reported after 0.5 to 4% of all antibiotic utilizations, dependent on gender and the specific antibiotic used. 4. Expect a higher incidence of new intolerances in individuals with three or more medication intolerances already noted in their medical records. 5. For individuals with an appropriate penicillin class antibiotic intolerance based on a history of anaphylaxis, urticaria, macular papular rashes, unknown symptoms, or symptoms not excluded in step one, proceed with penicillin skin testing. Skin test with penicilloyl-poly-lysine and native penicillin. If skin test is negative, proceed with an oral amoxicillin challenge. If skin test and oral challenge are negative, penicillin class antibiotics may be used. If skin test or oral challenge is positive, avoid penicillin class antibiotics. If skin test or oral challenge is positive, non-penicillin-beta-lactams may be used, unless there is a history of intolerance to a specific non-penicillin-beta-lactam, then avoid that specific non-penicillin-beta-lactam. If there is life-threatening infection that can only be treated with a penicillin class antibiotic, proceed with oral penicillin desensitization prior to any oral or parenteral penicillin use. 6. For individuals with an appropriate non-penicillin-beta-lactam intolerance, avoid re-exposure to the beta-lactam implicated. An alternative beta-lactam may be used, ideally with different side

    Full Text Available Lysinuric protein intolerance (LPI, also known as cationic aminoaciduria, hyperdibasic aminoaciduria type 2, or familial protein intolerance, is an autosomal recessive defect of diamino acid transport. LPI is characterized by the inability of the body to digest and utilize certain amino acids, namely lysine, arginine, and ornithine. As a result, there is an increased excretion of these amino acids, which in turn affects the liver, the gastrointestinal tract, lungs, immune system, spleen, and organs producing blood. We report a 5-month-old girl born of third degree consanguineous marriage who presented with hepatosplenomegaly with sepsis and worsening jaundice due to LPI.

    Lactose intolerance is widespread, with adult-type hypolactasia being the predominant cause of lactose malabsorption. Daily ingestion of less than 240 mL of milk is well tolerated by most lactose-intolerant adults. Some persons with normal lactase activity may become symptomatic on consumption of products containing lactose. Lactose maldigestion may coexist in adults with irritable bowel syndrome and in children with recurrent abdominal pain. Management consists primarily of dietary changes. People who avoid dairy products should receive calcium supplementation and should be advised to read ingredient labels carefully. Several lactase replacement products are available, but their efficacy varies.

    Regular use of aspirin can reduce cancer incidence, recurrence, metastasis and cancer-related mortality. Aspirin suppresses proliferation and induces apoptosis and autophagy in colorectal cancer cells, but the precise mechanism is not clear. In this study, we demonstrated that aspirin induced autophagosome formation in colorectal cancer cells, but autophagic degradation was blocked through aspirin-mediated Beclin 1 acetylation. Blocked autophagic degradation weakened aspirin-induced cell deat...

    Aspirin, one of the oldest and most common anti-inflammatory agents, has recently been shown to reduce cancer risks. The principal pharmacological effects of aspirin are known to arise from its covalent modification of cyclooxygenase-2 (COX-2) through acetylation of Ser530, but the detailed mechanism of its biochemical action and specificity remains to be elucidated. In this work, we have filled this gap by employing a state-of-the-art computational approach, Born-Oppenheimer molecular dynamics simulations with ab initio quantum mechanical/molecular mechanical potential and umbrella sampling. Our studies have characterized a substrate-assisted inhibition mechanism for aspirin acetylating COX: it proceeds in two successive stages with a metastable tetrahedral intermediate, in which the carboxyl group of aspirin serves as the general base. The computational results confirmed that aspirin would be 10-100 times more potent against COX-1 than against COX-2, and revealed that this inhibition specificity between the two COX isoforms can be attributed mainly to the difference in kinetics rate of the covalent inhibition reaction, not the aspirin-binding step. The structural origin of this differential inhibition of the COX enzymes by aspirin has also been elucidated.

    Aspirin taken for several years at doses of at least 75 mg daily reduced long-term incidence and mortality due to colorectal cancer. The finding of aspirin benefit at low-doses given once daily, used for cardioprevention, locates the antiplatelet effect of aspirin at the center of its antitumor efficacy. In fact, at low-doses, aspirin acts mainly by an irreversible inactivation of platelet cyclooxygenase (COX)-1 in the presystemic circulation, which translates into a long-lasting inhibition of platelet function. Given the short half-life of aspirin in the human circulation(approximately 20 min) and the capacity of nucleated cells to resynthesize the acetylated COX-isozyme(s), it seems unlikely that a nucleated cell could be the target of aspirin chemoprevention. These findings convincingly suggest that colorectal cancer and atherothrombosis may share a common mechanism of disease, i.e. platelet activation in response to epithelial(in tumorigenesis) and endothelial(in tumorigenesis and atherothrombosis) injury. Activated platelets may also enhance the metastatic potential of cancer cells (through a direct interaction and/or the release of soluble mediators or exosomes) at least in part by inducing the overexpression of COX-2. COX-independent mechanisms of aspirin, such as the inhibition of NF-kB signaling and Wnt/β-catenin signaling and the acetylation of extra-COX proteins, have been suggested to play a role in its chemopreventive effects. However, their relevance remains to be demonstrated in vivo at clinical doses.

    Asthma is a chronic disorder affecting millions of people worldwide. The prevalence of asthma is around 300 million and is expected to increase another 100 million by 2025. Obesity, on the other hand, also affects a large number of individuals. Overweight in adults is defined when body mass index (BMI) is between 25 to 30 kg/m 2 and obesity when the BMI >30 kg/m 2 . It has been a matter of interest for researchers to find a relation between these two conditions. This knowledge will provide a ...

    Infantile asthama is an important pediatric problem and may cause substantial morbidity and mortality in this age group. The pathophysiology of allergic asthma involves a type I hypersensitivity reaction that is mediated by reaginic antibodies of the IgE class. Various factors predisposing to infantile asthma have been suggested but not confirmed. The differential diagnosis of infantile wheezing is of particular importance in this very young age group. An appreciation of the natural history and clinical characteristics of the disease, and of the important causative factors (foods, environmental inhalants, and respiratory infections), will aid the physician in the management of this problem.

    Full Text Available OBJECTIVES: Severe asthma is found in approximately 10% of patients with asthma. Some factors associated with worse asthma control include rhinitis, gastroesophageal reflux disease, vocal cord dysfunction (VCD, nasal polyposis and bronchiectasis. Therefore, we evaluated the prevalence of these illnesses in patients with severe asthma. METHODS: We conducted a retrospective analysis of data obtained from electronic medical records of patients with severe asthma between January 2006 and June 2008. Symptoms of rhinitis and gastroesophageal reflux disease were evaluated as well as intolerance to nonsteroidal anti-inflammatory drugs. We evaluated the results of esophagogastroduodenoscopy, videolaryngoscopy and CT scans of the chest in order to confirm gastroesophageal reflux disease, nasal polyposis, vocal cord dysfunction and bronchiectasis. RESULTS: We evaluated 245 patients. Rhinitis symptoms were present in 224 patients (91.4%; 18 (7.3% had intolerance to nonsteroidal anti-inflammatory drugs, and 8 (3.3% had nasal polyposis. Symptoms of gastroesophageal reflux disease were reported for 173 (70.6% patients, although the diagnosis of gastroesophageal reflux disease was confirmed based on esophagogastroduodenoscopy or laryngoscopy findings in just 58 (33.6% patients. Vocal cord dysfunction was suspected in 16 (6.5% and confirmed through laryngoscopy in 4 (1.6%. The patient records provided CT scans of the chest for 105 patients, and 26 (24.8% showed bronchiectasis. DISCUSSION: Rhinitis and gastroesophageal reflux disease were the most common comorbidities observed, in addition to bronchiectasis. Therefore, in patients with severe asthma, associated diseases should be investigated as the cause of respiratory symptoms and uncontrolled asthma.

    Tartrazine is an artificial azo dye commonly used in human food and pharmaceutical products. Since the last assessment carried out by the JECFA in 1964, many new studies have been conducted, some of which have incriminated tartrazine in food intolerance reactions. The aims of this work are to update the hazard characterization and to revaluate the safety of tartrazine. Our bibliographical review of animal studies confirms the initial hazard assessment conducted by the JECFA, and accordingly the ADI established at 7.5mg/kg bw. From our data, in France, the estimated maximum theoretical intake of tartrazine in children is 37.2% of the ADI at the 97.5th percentile. It may therefore be concluded that from a toxicological point of view, tartrazine does not represent a risk for the consumer. It appears more difficult to show a clear relationship between ingestion of tartrazine and the development of intolerance reactions in patients. These reactions primarily occur in patients who also suffer from recurrent urticaria or asthma. The link between tartrazine consumption and these reactions is often overestimated, and the pathogenic mechanisms remain poorly understood. The prevalence of tartrazine intolerance is estimated to be less than 0.12% in the general population. Generally, the population at risk is aware of the importance of food labelling, with the view of avoiding consumption of tartrazine. However, it has to be mentioned that products such as ice creams, desserts, cakes and fine bakery are often sold loose without any labelling.

    Sodium chromate Cr 51 was used to label red blood cells of 19 healthy male volunteers, whose stools were collected for four days before and four days during oral administration of either uncoated (N . 9) or enteric-coated (N . 10) aspirin. Each subject received 2.925 gm/day of aspirin, in three equal doses separated by eight-hour intervals, for a total of seven days. During drug use, stools were collected on days 4 through 7. Fecal blood content, estimated by measuring radioactivity in the stools, was significantly higher (P less than 0.001) during use of either type of aspirin than at baseline, but losses measured during use of the coated aspirin (mean, 1.54 ml/day) were significantly lower (P less than 0.001) than those measured during use of the uncoated aspirin (mean, 4.33 ml/day). The two types of aspirin produced equivalent serum concentrations of salicylates. We conclude that enteric-coated aspirin reduces gastrointestinal blood loss.

    Nilotinib has significant efficacy in patients with newly diagnosed chronic myeloid leukemia in chronic phase (CML-CP) and in patients with CML-CP or CML in accelerated phase (CML-AP) after imatinib failure. We investigated the occurrence of cross-intolerance to nilotinib in imatinib-intolerant patients with CML. Only 1/75 (1%) patients with nonhematologic imatinib intolerance experienced a similar grade 3/4 adverse event (AE), and 3/75 (4%) experienced a similar persistent grade 2 nonhematologic AE on nilotinib. Only 7/40 (18%) patients with hematologic imatinib intolerance discontinued nilotinib, all because of grade 3/4 thrombocytopenia. Ninety percent of imatinib-intolerant patients with CML-CP who did not have complete hematologic response (CHR) at baseline (n = 52) achieved CHR on nilotinib. Nilotinib induced a major cytogenetic response in 66% and 41% of patients with imatinib-intolerant CML-CP and CML-AP (complete cytogenetic response in 51% and 30%), respectively. Minimal cross-intolerance was confirmed in patients with imatinib-intolerant CML. The favorable tolerability of nilotinib in patients with imatinib intolerance leads to alleviation of AE-related symptoms and significant and durable responses. In addition to its established clinical benefit in patients with newly diagnosed CML and those resistant to imatinib, nilotinib is effective and well-tolerated for long-term use in patients with imatinib intolerance.

    Aspirin desensitization is an effective treatment option for aspirin-exacerbated respiratory disease. Aspirin desensitization protocol modifications have improved the safety and efficiency of this procedure, yet some providers remain reluctant to perform it. The primary objective of this study was to evaluate the safety and outcomes of outpatient aspirin desensitization procedures. A secondary objective was to assess clinical characteristics that might predict reaction severity during aspirin desensitization. Two hundred seventy-five patients underwent aspirin desensitization at Scripps Clinic between January 2009 and August 2015. Baseline patient characteristics and reaction results were analyzed in the 167 patients who reacted during desensitization. All of the 167 reactors, including 23 who were classified as severe reactors, were successfully desensitized in the outpatient setting. The average desensitization duration among reactors was 1.67 days, and the average duration for gastrointestinal reactors was 2.29 days. The mean baseline Sino-Nasal Outcome Test score was higher in severe reactors compared with nonsevere reactors (P = .05). Overall, patients receiving omalizumab had a similar reaction profile to those not receiving omalizumab. Most patients undergoing aspirin desensitization will have symptoms. It remains difficult to predict the severity of these symptoms. However, desensitization can be done safely and efficiently in an appropriately equipped outpatient setting. This treatment option should be made available to all patients with aspirin-exacerbated respiratory disease. The Sino-Nasal Outcome Test score might be able to predict more severe reactions and merits further study. Eight of the 9 patients receiving omalizumab reacted during desensitization, suggesting that it does not block reactions during aspirin desensitization. Published by Elsevier Inc.
