Aspirin causes bronchoconstriction in aspirin-intolerant asthma (AIA) patients by triggering cysteinyl-leukotriene (cys-LT) production, probably by removing PGE2-dependent inhibition. To investigate why aspirin does not cause bronchoconstriction in all individuals, we immunostained enzymes of the leukotriene and prostanoid pathways in bronchial biopsies from AIA patients, aspirin-tolerant asthma (ATA) patients, and normal (N) subjects. Counts of cells expressing the terminal enzyme for cys-LT...

Full Text Available Abstract Background Aspirin-intolerant asthma (AIA, which is caused by non-steroidal anti-inflammatory drugs (NSAIDs such as aspirin, causes lung inflammation and reversal bronchi reduction, leading to difficulty in breathing. Aspirin is known to affect various parts inside human body, ranging from lung to spermatogenesis. FSIP1, also known as HDS10, is a recently discovered gene that encodes fibrous sheath interacting protein 1, and is regulated by amyloid beta precursor protein (APP. Recently, it has been reported that a peptide derived from APP is cleaved by α disintegrin and metalloproteinase 33 (ADAM33, which is an asthma susceptibility gene. It has also been known that the FSIP1 gene is expressed in airway epithelium. Objectives Aim of this study is to find out whether FSIP1 polymorphisms affect the onset of AIA in Korean population, since it is known that AIA is genetically affected by various genes. Methods We conducted association study between 66 single nucleotide polymorphisms (SNPs of the FSIP1 gene and AIA in total of 592 Korean subjects including 163 AIA and 429 aspirin-tolerant asthma (ATA patients. Associations between polymorphisms of FSIP1 and AIA were analyzed with sex, smoking status, atopy, and body mass index (BMI as covariates. Results Initially, 18 SNPs and 4 haplotypes showed associations with AIA. However, after correcting the data for multiple testing, only one SNP showed an association with AIA (corrected P-value = 0.03, OR = 1.63, 95% CI = 1.23-2.16, showing increased susceptibility to AIA compared with that of ATA cases. Our findings suggest that FSIP1 gene might be a susceptibility gene for aspirin intolerance in asthmatics. Conclusion Although our findings did not suggest that SNPs of FSIP1 had an effect on the reversibility of lung function abnormalities in AIA patients, they did show significant evidence of association between the variants in FSIP1 and AIA occurrence among asthmatics in a Korean population.

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...

Cysteinyl leukotrienes (cysLTs) are considered to be the most important mediator involved in the pathogenesis of aspirin-intolerant asthma (AIA). However, the role of cysLTs in the baseline condition of the pathophysiology of AIA when not exposed to non-steroidal antiinflammatory drugs (NSAIDs) as well as that in the pathophysiology of aspirin-tolerant asthma remains to be elucidated. Therefore, we evaluated the effect of pranlukast, a potent, selective cysLT receptor antagonist, on bronchial...

Aspirin-induced asthma (AIA) is a distinct clinical syndrome characterized by severe asthma exacerbations after ingestion of aspirin or other non-steroidal anti-inflammatory drugs. The exact pathomechanism of AIA remains unknown, though ongoing research has shed some light. Recently, more and more attention has been focused on the role of aspirin in the induction of oxidative stress, especially in cancer cell systems. However, it has not excluded the similar action of aspirin in other inflamm...

Although intolerance reaction to analgesics are not uncommon, there is still a lack of standardized procedures to diagnose the problem. We retrospectively analyzed results of scratch tests as well as oral challenges with analgesics in order to evaluate risk and diagnostic relevance of these procedures. In 1987-1992 a total of 650 patients with supposed intolerance to drugs were tested by oral challenge. Among them were 98 patients with a positive history of intolerance to non-aspirin analgesics. In 56 patients the intolerance could be verified by oral challenge. In order of decreasing frequency, the most likely agents were propyphenazone, diclofenac, metamizole, ibuprofen, carbamazepine, indomethacin, phenazone (antipyrine), and paracetamol (acteaminophen). Oral provocation showed clear dose-response relationships. For propyphenazone, the half-effective provocation dose was the same for all symptoms (cutaneous, nasal, bronchial, anaphylactoid). Scratch testing was not of diagnostic significance. Standardized test protocols starting with low dose oral challenges are suitable and helpful in minimizing the risk of severe side effects.

BACKGROUND--An abnormal platelet release of oxygen-free radicals has been described in acetylsalicylic acid (aspirin)-induced asthma, a finding which might suggest the existence of an intrinsic, specific platelet abnormality of arachidonic acid metabolism in these patients. The objective of this study was to evaluate platelet arachidonic acid metabolism in asthmatic patients with or without intolerance to aspirin. METHODS--Thirty subjects distributed into three groups were studied: group 1, 1...

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...
Full Text Available 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.

Aspirin intolerant asthma (AIA) is frequently characterized as an aspirin (ASA)-exacerbated respiratory disease (AERD). It is a clinical syndrome associated with chronic severe inflammation in the upper and lower airways resulting in chronic rhinitis, sinusitis, recurrent polyposis, and asthma. AERD generally develops secondary to abnormalities in inflammatory mediators and arachidonic acid biosynthesis expression. Upper and lower airway eosinophil infiltration is a key feature of AERD; howev...

Aspirin-exacerbated diseases are important examples of drug hypersensitivities and include aspirin-exacerbated respiratory disease (AERD), aspirin- or non-steroidal anti-inflammatory drug (NSAID)-induced urticaria/angioedema, and aspirin- or NSAID-induced anaphylaxis. While each disease subtype may be distinguished by unique clinical features, the underlying mechanisms that contribute to these phenotypes are not fully understood. However, the inhibition of the cyclooxygenase-1 enzyme is thought to play a significant role. Additionally, eosinophils, mast cells, and their products, prostaglandins and leukotrienes, have been identified in the pathogenesis of AERD. Current diagnostic and treatment strategies for aspirin-exacerbated diseases remain limited, and continued research focusing on each of the unique hypersensitivity reactions to aspirin is essential. This will not only advance the understanding of these disease processes, but also lead to the subsequent development of novel therapeutics that patients who suffer from aspirin-induced reactions desperately need.

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

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 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.

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 ...

Asthma and chronic rhinosinusitis are heterogeneous airway diseases of the lower and upper airways, respectively. Molecular and cellular studies indicate that these diseases can be categorized into unique endotypes, which have therapeutic implications. One such endotype is aspirin-exacerbated respiratory disease (AERD), which encompasses the triad of asthma, aspirin (or nonsteroidal anti-inflammatory drug) hypersensitivity, and nasal polyposis. AERD has unique pathophysiological features that distinguish it from aspirin-tolerant asthma and other forms of chronic rhinosinusitis. This review details molecular and cellular features of AERD and highlights current and future therapies that are based on these insights. PMID:27022293

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.

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.

Aspirin-exacerbated respiratory disease (AERD) is an adult-onset upper and lower airway disease consisting of eosinophilic nasal polyps, asthma, and respiratory reactions to cyclooxygenase 1 (COX-1) inhibitors. Management includes guideline-based treatment of asthma and sinus disease, avoidance of COX-1 inhibitors, and for some patients aspirin desensitization followed by high-dose aspirin therapy. Despite this, many patients have inadequately controlled symptoms and require multiple sinus surgeries. In this review, we discuss the current standard approaches to the management of AERD, and we introduce several therapeutics under development that may hold promise for the treatment of AERD.

Acute severe asthma, formerly known as status asthmaticus, is defined as severe asthma unresponsive to repeated courses of beta-agonist therapy such as inhaled albuterol, levalbuterol, or subcutaneous epinephrine. It is a medical emergency that requires immediate recognition and treatment. Oral or parenteral corticosteroids should be administered to all patients with acute severe asthma as early as possible because clinical benefits may not occur for a minimum of 6-12 hours. Approximately 50% of episodes are attributable to upper respiratory infections, and other causes include medical nonadherence, nonsteroidal anti-inflammatory exposure in aspirin-allergic patients, allergen exposure (especially pets) in severely atopic individuals, irritant inhalation (smoke, paint, etc.), exercise, and insufficient use of inhaled or oral corticosteroids. The patient history should be focused on acute severe asthma including current use of oral or inhaled corticosteroids, number of hospitalizations, emergency room visits, intensive-care unit admissions and intubations, the frequency of albuterol use, the presence of nighttime symptoms, exercise intolerance, current medications or illicit drug use, exposure to allergens, and other significant medical conditions. Severe airflow obstruction may be predicted by accessory muscle use, pulsus paradoxus, refusal to recline below 30°, a pulse >120 beats/min, and decreased breath sounds. Physicians' subjective assessments of airway obstruction are often inaccurate. More objective measures of airway obstruction via peak flow (or forced expiratory volume in 1 second) and pulse oximetry before oxygen administration usually are helpful. Pulse oximetry values >90% are less commonly associated with problems although CO(2) retention and a low Pao(2) may be missed. PMID:22794687

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. PMID:27489545

Aspirin is widely used for the prevention of recurrent stroke in patients with transient ischaemic attack (TIA) of arterial origin, because it is effective and inexpensive. Clopidogrel and the combination of aspirin and extended-release dipyridamole are more effective than aspirin, but are also much more expensive. No other antithrombotic regimens provide significant advantages over aspirin, although cilostazol and the novel platelet protease-activated receptor-1 antagonist, SCH 530348, are c...
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.
Food allergies and intolerance Summary It is rather necessary to distinguish between food allergy and food intolerance. While the nature of allergy is based on the immunological response, intolerance may be mostly caused by the lack of an enzyme that is needed to digest certain foods seamlessly. Clinical manifestations may be varied. These may be a more serious case of anaphylactic reaction, oral allergy syndrome, dermatological symptoms, gastrointestinal reactions or as respirato...

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.

Factors affecting or confounding the symptoms of lactose intolerance were examined by us in randomised, placebo-controlled and double-blind studies on healthy adult subjects. Evaluation of the diagnostic methods of lactose intolerance showed that cut-off values, according to the blood glucose values, varied widely. This result was based on a postal questionnaire, sent to all Finnish health centres. Symptoms were seldom recorded for a sufficiently long period. In carefully diagnosed lactose in...

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 intractable asthma. The number of patients with asthma has increased, and that of patients who die from asthma has decreased (1.5 per 100,000 patients in 2012. The aim of asthma treatment is to enable patients with asthma to lead a normal life without any symptoms. A good relationship between physicians and patients is indispensable for appropriate treatment. Long-term management with antiasthmatic 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. Long-acting 02-agonists, leukotriene receptor antagonists, and sustained-release theophylline are recommended as concomitant drugs, while anti-immunoglobulin E antibody therapy has been recently developed for the most severe and persistent asthma involving allergic reactions. Inhaled 02-agonists, aminophylline, corticosteroids, adrenaline, oxygen therapy, and others are used as needed in acute exacerbations by choosing treatment steps for asthma exacerbations depending on the severity of attacks. Allergic rhinitis, chronic obstructive pulmonary disease, aspirin-induced asthma, pregnancy, asthma in athletes, and coughvariant asthma are also important issues that need to be considered.

Specific food intolerance needs to be distinguished from obsessional states in which those who are affected have an aversion to numerous foods. Even in cases where specific food intolerance can be demonstrated, the diagnosis of food allergy depends on additional evidence that the patient's reaction is based on an abnormal immunological response. In food allergy, skin and laboratory tests may detect the presence of an IgE-mediated reaction, particularly in patients with asthma or eczema and especially where the foods involved are highly allergenic--such as egg, fish, nuts and milk. However, many patients with proven food intolerance have negative tests, suggesting that other immunological or non-immunological mechanisms are responsible. Laboratory tests for non-IgE reactions are unreliable. Where it is difficult to show a connection between individual foods and an allergic response--as in patients with urticaria provoked by food additives--one of the reasons for diagnostic difficulty is that the offending substances may be present in a wide range of common foods. If the diagnosis is to be firmly established in such cases, it is necessary to show that symptoms remit on an elimination diet and recur after a placebo-controlled challenge. PMID:6351151

hypersensitivity reactions, in particular Aspirin-induced asthma, and potential cross-reactions with other frequently used NSAIs. The most susceptible sub-population for asthmatic reactions has well-defined features. The anti-aggregation effects of Aspirin can complicate some conditions associated to hemostasis disorders; however, its benefit has been shown for the prevention of athero-thrombotic vascular accidents. The Reye´s Syndrome is a rare but severe condition in which the use of Aspirin is contraindicated in children or adolescents with fever or certain viral infections. Given the extensive use of Aspirin, it can generally be considered a well-tolerated drug whose most severe adverse reactions require special pharmacovigilance, as well as special attention to high risk populations. This also suggests the need to implement health education programs about the use of analgesics. In any case, Aspirin is still a reference drug with a high therapeutic potential derived from the benefits provided by its use.

Aspirin idiosyncrasy must be watched for, particularly in the elderly, where nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently used for osteoarthritis, bursitis, and related musculoskeletal disorders. An electrocardiogram is advised to exclude or define underlying cardiac disease in elderly asthmatics. They may suffer cardiopulmonary reverses that invariably are perceived as acute asthma by the patient. PMID:6873636

Exercise intolerance (EI) is a frequent cause of medical attention, although it is sometimes difficult to come to a final diagnosis. However, there is a group of patients in whom EI is due to a metabolic dysfunction. McArdle's disease (type V glucogenosis) is due to myophosphorylase (MPL) deficiency. The ischemic exercise test shows a flat lactate curve. The most frequent mutations in the PYGM gene (MPL gene) in Spanish patients with MPL deficiency are R49X and W797R. Carnitine palmitoyltransferase (CPT) II deficiency is invariably associated to repetitive episodes of myoglobinuria triggered by exercise, cold, fever or fasting. The diagnosis depends on the demonstration of CPT II deficiency in muscle. The most frequent mutation in the CPT2 gene is the S113L. Patients with muscle adenylate deaminase deficiency usually show either a mild myopathy or no symptom. The diagnosis is based on the absence of enzyme activity in muscle and the lack of rise of ammonia in the forearm ischemic exercise test. The mutation Q12X in the AMPD1 gene is strongly associated with the disease. Exercise intolerance is a common complaint in patients with mitochondrial respiratory chain (MRC) deficiencies, although it is often overshadowed by other symptoms and signs. Only recently we have come to appreciate that exercise intolerance can be the sole presentation of defects in the mtDNA, particularly in complex I, complex III, complex IV, or in some tRNAs. In addition, myoglobinuria can be observed in patients under statin treatment, particularly if associated with fibrates, due to an alteration in the assembly of the complex IV of the MRC.

Hereditary fructose intolerance (HFI) is an underrecognized,preventable life-threatening condition. It is an autosomal recessive disorder with subnormal activity of aldolase B in the liver, kidney and small bowel. Symptoms are present only after the ingestion of fructose, which leads to brisk hypoglycemia, and an individual with continued ingestion will exhibit vomiting,abdominal pain, failure to thrive, and renal and liver failure. A diagnosis of HFI was made in a 50-year-old woman on the basis of medical history, response to Ⅳ fructose intolerance test, demonstration of aldolase B activity reduction in duodenal biopsy, and molecular analysis of leukocyte DNA by PCR showed homozygosity for two doses of mutant gene. HFI may remain undiagnosed until adult life and may lead to disastrous complications following inadvertent fructose or sorbitol infusion. Several lethal episodes of HFI following sorbitol and fructose infusion have been reported. The diagnosis can only be suspected by taking a careful dietary history, and this can present serious complications.

First used as an analgesic and antipyretic, investigations into aspirin’s anti-inflammatory effects led to its establishment in 1974 as a drug that altered the activity of platelets to influence the course and incidence of myocardial infarction and cerebrovascular disease. It became the standard in treatment and prevention of vascular disorders. The 25th International Scientific Meeting on aspirin held at the Royal College of Physicians in London on 24th October 2012 took aspirin into fresh f...

Aspirin-exacerbated respiratory disease (AERD) is an adult-onset condition that manifests as asthma, rhinosinusitis/nasal polyps, and sensitivity to aspirin and other cyclooxygenase-1 (COX-1)-inhibitor nonsteroidal anti-inflammatory drugs (NSAIDs). There is no cross-sensitivity to highly selective COX-2 inhibitors. AERD is chronic and does not improve with avoidance of COX-1 inhibitors. The diagnosis of AERD is made through provocative challenge testing. Following a positive aspirin challenge, patients can be desensitized to aspirin and NSAIDs. The desensitized state can be maintained indefinitely with continued daily administration. After desensitization, there is an approximately 48-hour refractory period to adverse effects from aspirin. The pathogenesis of AERD remains unknown, but these patients have been shown to have multiple abnormalities in arachidonic acid metabolism and in cysteinyl leukotriene 1 receptors. AERD patients can take up to 650 mg of acetaminophen for analgesic or antipyretic relief. Patients can also use weak COX-1 inhibitors, such as sodium salicylate or choline magnesium trisalicylate. Treatment of AERD patients with antileukotriene medications has been helpful but not preferential when compared with non-AERD patients. An alternative treatment for many AERD patients is aspirin desensitization. This is particularly effective in reducing upper-airway mucosal congestion, nasal polyp formation, and systemic steroids.

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. PMID:6391293

We wanted to determine whether the airway response to inhaled leukotriene C4 (LTC4) is similar to inhaled leukotriene E4 (LTE4) in aspirin-sensitive asthma and, therefore, determined airway responsiveness to histamine, LTC4 and LTE4 in seven aspirin-sensitive subjects and 13 control asthmatic subjects, who were tolerant of aspirin. The concentration of inhaled lysine-aspirin which produced a 15% fall in forced expiratory volume in one second (FEV1) (PC15) was determined in aspirin-sensitive asthmatic subjects. The dose of histamine, LTC4 and LTE4 which produced a 35% fall in specific airways conductance (PD35sGaw) was determined by linear interpolation from the log dose response curve. There was no correlation between the PC15 for lysine-aspirin and the airway reactivity to inhaled LTC4 or LTE4. There was no difference in airway response to histamine and LTC4 between any of the groups of asthmatic subjects. There was a rank order of potency LTC4 > LTE4 > histamine in both groups, with LTC4 approximately 1,000 fold more potent than histamine in both groups. Aspirin-sensitive asthmatic subjects were significantly more responsive to LTE4 (p = 0.02) than aspirin-tolerant asthmatic subjects. The relative responsiveness of LTE4 to histamine (PD35 histamine/PD35 LTE4) was significantly greater in aspirin-sensitive asthmatic subjects compared to aspirin-tolerant asthmatic subjects (p = 0.05). There was no difference in relative responsiveness of LTC4 to histamine between aspirin-sensitive or aspirin-tolerant asthmatic subjects. We conclude that the airways of aspirin-sensitive asthmatic subjects demonstrate a selective hyperresponsiveness to LTE4, which is not observed for LTC4. PMID:8112440

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 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.

Technetium-aspirin and technetium-aspirin-like molecule complexes were prepared. The structure of N-acetylanthranilic acid (NAA) has been decided through CNDO calculations. 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)

Chemical intolerance, or reported illness from odors of common environmental chemicals (e.g., car exhaust, pesticides), is emerging as an important environmental and public health-care issue. Epidemiologic methods provide relevant heuristic devices for studies of complex disorders, such as chemical intolerance. The authors examined personal and reported parental cardiopulmonary disease prevalence rates in a community sample of chemically intolerant and control individuals. A county government (Tucson, Arizona) employee and kin subset (N = 181; 113 households) completed standard health questionnaires. Investigators determined chemical intolerance (n = 41/181) from self-reports of individuals who felt "moderately" to "severely" ill from exposure to at least three of five chemicals (i.e., car exhaust, pesticides, paint, new carpet, and perfume) on a Chemical Odor Intolerance Index. The authors chose the control group (n = 57/181) on the basis of self-reports of "never" feeling ill on the Chemical Odor Intolerance Index. The chemically intolerant group, which primarily comprised women (78% versus 51% of controls, p < .05), was significantly more likely to report-and to have sought--medical attention for heart problems, bronchitis, asthma, and pneumonia. Reports of heart problems in the chemically intolerant index cases and the occurrence of heart disease in both of their parents were significant (Fisher's p < .05). The chemically intolerant individuals were also significantly more likely to report maternal histories of chest problems (e.g., inhalant allergens, tuberculosis) than controls. The findings of the study suggested that the chemically intolerant individuals (a preponderance of whom were women [sex-related risk]) were more likely to have (a) reported cardiopulmonary problems (i.e., greater health risk); (b) actively sought medical care for these problems (i.e., increased medical utilization); and (c) reported more parental illnesses-particularly heart disease
Occupational asthma is defined as “a disease of variable airflow limitations and/or airway hyper-responsiveness due to causes and conditions attributable to a particular occupational environment and not stimuli that are being encountered outside the workplace.” An analysis of general population-based studies published up to 2007 showed that 17.6% of all adultonset asthma is due to workplace exposures. In this article, Different aspects of occupational asthma are briefly reviewed.

Main causes of asthma are allergy, smoking, drugs like NSAID (Aspirin and family history. Objective of study was to check the prevalence of asthma in different age groups and its impact on socioeconomical behaviors of the peoples of southern Punjab, by developing a questionnaire. Incidence of asthmatic attack in the age group of 20 to 60 years was more than in age group of 20 years, furthermore the incidence was found to be more common in females as compare to males. The smokers were at more risk to develop the disease as compared to the nonsmokers.

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...

Intolerance to foods which contain lactose can cause a range of intestinal and systemic symptoms. These symptoms are caused by Lactase deficiency which is encoded by a single gene (LCT) of ≈ 50 kb located on chromosome 2q21. In some food items, lactose has been missed because of "hidden" lactose due to inadequately labeled, confusing diagnosis of lactose intolerance based on dietary restriction of dairy foods. Two polymorphisms, C/T13910 and G/A22018, linked to hypolactasia, correlate with breath hydrogen and symptoms after lactose. The key in the management of lactose intolerance is the dietary removal of lactose. Patients diagnosed as lactose intolerant must be advised of "risk" foods, inadequately labeled, including processed meats, bread, cake mixes, soft drinks, and lagers. This review highlights the types, symptoms and management of lactose intolerance and also highlights differences from milk allergy which closely mimics the symptoms of lactose intolerance.

Dairy products provide us with calcium and other valuable nutrients. However, they also contain lactose which is maldigested by a large part of the world adult population. The mechanisms by which lactose maldigestion causes symptoms of lactose intolerance are not fully understood.

Limited evidence suggests that colonic metabolism of lactose, in addition to the smal...

An important consensus today is that intolerance and social conflict have a substantial economic dimension. This article models a person’s “returns” to acts of intolerance in terms of social approval or disapproval that this person’s peer-group may offer. It is found that high levels of intolerance may persist, that is, society is “in equilibrium,” even as this imposes economic costs.

Conclusion The recurrence rates of chronic rhinosinusitis (CRS) were higher in the aspirin nasal provocation test (ANPT)-positive group, regardless of the presence of nasal polyps. Thus, a careful endoscopic examination is required during follow-up in ANPT-positive patients with CRS. Objectives The aim of this study was to evaluate the clinical features and prognosis after surgical treatment in patients with CRS and aspirin hypersensitivity. Methods In a prospective study, 100 patients were analyzed with CRS who underwent endoscopic sinus surgery at the hospital from October 2012 to March 2013. This study measured changes in nasal volume and symptoms before and after the ANPT and examined patient's asthma history, allergy, Lund-Mackay score (LMS), total immunoglobulin E, percentage of peripheral eosinophils, and objectively measured relapse at 6 months. Results Patients wwith CRS and nasal polyps (CRSwNP) were more likely to have a positive ANPT test result compared to those without nasal polyps (CRSsNP) (21.4% vs 5.5%). The ANPT-positive group had a higher LMS and required more revision endoscopic sinus surgery than those in the ANPT-negative group. The results were that similar results were observed in CRSwNP and CRSsNP. PMID:26924187

Excessive accumulation of histamine in the body leads to miscellaneous symptoms mediated by its bond to corresponding receptors (H1-H4). Increased concentration of histamine in blood can occur in healthy individuals after ingestion of foods with high contents of histamine, leading to histamine intoxication. In individuals with histamine intolerance (HIT) ingestion of food with normal contents of histamine causes histamine-mediated symptoms. HIT is a pathological process, in which the enzymatic activity of histamine-degrading enzymes is decreased or inhibited and they are insufficient to inactivate histamine from food and to prevent its passage to blood-stream. Diagnosis of HIT is difficult. Multi-faced, non-specific clinical symptoms provoked by certain kinds of foods, beverages and drugs are often attributed to different diseases, such as allergy and food intolerance, mastocytosis, psychosomatic diseases, anorexia nervosa or adverse drug reactions. Correct diagnosis of HIT followed by therapy based on histamine-free diet and supplementation of diamine oxidase can improve patient's quality of life. PMID:26242570

1. The efficacy of three different single doses (600, 900 and 1200 mg of soluble aspirin and aspirin tablets) was determined in a randomized placebo-controlled parallel study in 140 patients (70 females) with postoperative pain after removal of impacted third molars. 2. Patients treated with soluble aspirin 600 mg, 900 mg, 1200 mg and aspirin tablet 1200 mg reported significantly less pain (P less than 0.01) throughout the investigation period than those treated with placebo. 3. Overall pain scores after treatment with aspirin tablets 600 and 900 mg did not differ significantly from those after treatment with placebo (P greater than 0.05). 4. On a comparative dose basis, soluble aspirin was significantly more potent (P less than 0.05) than aspirin tablets. PMID:3190996

Background: When lactose malabsorption gives rise to symptoms, the result is called 'lactose intolerance'. Although lactose intolerance is often bothersome for patients, once recognized it may be managed by simple dietary adjustments. However, diagnosing lactose intolerance is not straightforward, e
Full Text Available The objective of present study is to evaluate the effects of calcium carbonate and calcium gluconate on acute and subacute inflammation and to study their possible interactions with Aspirin. Calcium carbonate (10 mg/kg and calcium gluconate (5 mg/kg were administered individually and also co-administered along with sub therapeutic dose Aspirin (50mg/kg to study their interaction. The inflammation was induced by carrageenan or a foreign body. Both calcium carbonate and calcium gluconate could not show significant anti-inflammatory activity on their own in acute as well as subacute inflammation models. Aspirin at sub-anti-inflammatory dose (50mg/Kg when co-administered along with calcium salts produced the significant anti-inflammatory response which was comparable to anti-inflammatory response of aspirin at therapeutic dose (200mg/Kg. Also co-adminostration minimized the gastro-toxicity of aspirin.

Aspirin-exacerbated respiratory disease (AERD) is a common, severe variant of asthma, which is associated with overproduction of cysteinyl leukotrienes (cysLTs) and respiratory reactions to drugs that block cyclooxygenase 1. We demonstrate that mice selectively lacking the capacity to up-regulate the generation of prostaglandin E2 with inflammation develop an AERD-like phenotype that depends critically on platelets and thromboxane receptors, which drive transcellular synthesis of cysLTs, whic...

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.

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-...

Our group generalized the research development of lactose intolerance, both internationally and nationally. We systematically reviewed the pathogenesis, genetic polymorphisms of lactase deficiency, relevant progress of diagnostic methods and treatment. Through this systematic review, we undedrstood that there were insufficient research efforts made on understanding the epidemiological feature of lactose intolerance in this country. Relevant genetic mutations of people were also not clear, neither the development of simple and effective diagnosis method made. We should continue to extensively and deeply carry out the study regarding methods for early prevention and intervention on lactose intolerance. PMID:26917535

This review discusses one of the most relevant problems in gastrointestinal clinical practice: lactose intolerance. The role of lactase-persistence alleles the diagnosis of lactose malabsorption the development of lactose intolerance symptoms and its management. Most people are born with the ability to digest lactose, the major carbohydrate in milk and the main source of nutrition until weaning. Approximately, 75% of the world's population loses this ability at some point, while others can digest lactose into adulthood. Symptoms of lactose intolerance include abdominal pain, bloating, flatulence and diarrhea with a considerable intraindividual and interindividual variability in the severity. Diagnosis is most commonly performed by the non invasive lactose hydrogen breath test. Management of lactose intolerance consists of two possible clinical choice not mutually exclusive: alimentary restriction and drug therapy. PMID:24443063

Full Text Available Fructose intolerance is a metabolic disorder with hereditary determinism, clinically manifested on terms of fructose intake. Untreated, hereditary fructose intolerance may result in renal and hepatic failure. Unfortunately, there are no formal diagnostic and surveillance guidelines for this disease. If identified and treated before the occurrence of permanent organ damage, patients can improve their symptoms and self-rated health. Implementation and adherence to a strict fructose free diet is often difficult, but not impossible.

Lysinuric protein intolerance (LPI) is an autosomal recessive disease characterized by defective transport of cationic amino acids. Patients have an increased incidence of fractures and their skeletal radiographs show osteoporosis. The aim of the study was to characterize the osteopenia in LPI. Twenty-nine Finnish LPI patients (age range 3.7-44.4 years) were screened for parameters of bone metabolism. Morphometric analysis of bone was carried out in specimens of 9 patients. Collagen synthesis was studied with cultured skin fibroblasts (4 patients) and collagen fibril sizes (3 patients) were measured using electron microscopy. Most histological bone specimens (8/9) showed osteoporosis. Osteomalacia was excluded. Routine clinical laboratory tests were unrevealing. The concentrations of free hydroxyproline and type III procollagen N-propeptide in serum and the urinary excretion of hydroxyproline were increased in almost all patients during their growth and in about half of adult patients. Collagen synthesis in LPI fibroblast cultures was significantly decreased compared with that in age-matched controls at 5 (p < 0.01), 14 (p < 0.01) and still at 30 years (p < 0.01), whereas no difference was observed at the age of 44 years (p = N.S.). Osteoporosis in LPI might reflect defective matrix protein synthesis caused by protein deprivation and deficiency of cationic amino acids. Increased collagen turnover can also contribute to the osteoporosis. PMID:8412005
Full Text Available Abstract Background Although a large number of epidemiological studies have examined the role of aspirin in the chemoprevention of colon cancer and other solid tumors, there is a limited body of research focusing on the association between aspirin and lung cancer risk. Methods We conducted a hospital-based case-control study to evaluate the role of regular aspirin use in lung cancer etiology. Study participants included 868 cases with primary, incident lung cancer and 935 hospital controls with non-neoplastic conditions who completed a comprehensive epidemiological questionnaire. Participants were classified as regular aspirin users if they had taken the drug at least once a week for at least one year. Results Results indicated that lung cancer risk was significantly lower for aspirin users compared to non-users (adjusted OR = 0.57; 95% CI 0.41–0.78. Although there was no clear evidence of a dose-response relationship, we observed risk reductions associated with greater frequency of use. Similarly, prolonged duration of use and increasing tablet years (tablets per day × years of use was associated with reduced lung cancer risk. Risk reductions were observed in both sexes, but significant dose response relationships were only seen among male participants. When the analyses were restricted to former and current smokers, participants with the lowest cigarette exposure tended to benefit most from the potential chemopreventive effect of aspirin. After stratification by histology, regular aspirin use was significantly associated with reduced risk of small cell lung cancer and non-small cell lung cancer. Conclusions Overall, results from this hospital-based case-control study suggest that regular aspirin use may be associated with reduced risk of lung cancer.

Severe asthma in children is characterized by sustained symptoms despite treatment with high doses of ICS or oral corticosteroids. Children with severe asthma may fall into two categories, difficult-to-treat asthma or severe therapy-resistant asthma. Difficult-to-treat asthma is defined as poor control due to an incorrect diagnosis or comorbidities, poor adherence due to adverse psychological or environmental factors. In contrast, treatment-resistant is defined as difficult asthma despite man...

"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. PMID:26715082

In patients with coronary artery disease (CAD), though aspirin inhibits platelet activation and reduces atherothrombotic complications, it does not always sufficiently inhibit platelet function, thereby causing a clinical situation known as aspirin resistance. As hyperuricemia activates platelet turnover, aspirin resistance may be specifically induced by increased serum uric acid (SUA) levels. In this study, we thus investigated the association between SUA level and aspirin resistance in patients with CAD. We analyzed 245 consecutive patients with stable angina pectoris (SAP) who in coronary angiography showed more than 50% occlusion in a major coronary artery. According to aspirin resistance, two groups were formed: the aspirin resistance group (Group 1) and the aspirin-sensitive group (Group 2). Compared with those of Group 2, patients with aspirin resistance exhibited significantly higher white blood cell counts, neutrophil counts, neutrophil-to-lymphocyte ratios, SUA levels, high-sensitivity C-reactive protein levels, and fasting blood glucose levels. After multivariate analysis, a high level of SUA emerged as an independent predictor of aspirin resistance. The receiver-operating characteristic analysis provided a cutoff value of 6.45 mg/dl for SUA to predict aspirin resistance with 79% sensitivity and 65% specificity. Hyperuricemia may cause aspirin resistance in patients with CAD and high SUA levels may indicate aspirin-resistant patients. Such levels should thus recommend avoiding heart attack and stroke by adjusting aspirin dosage. PMID:26656902
Full Text Available BACKGROUND: Aspirin-exacerbated respiratory disease (AERD refers to the development of bronchoconstriction in asthmatics following the ingestion of aspirin. Although alterations in eicosanoid metabolites play a role in AERD, other immune or inflammatory mechanisms may be involved. We aimed to identify proteins that were differentially expressed in nasal polyps between patients with AERD and aspirin-tolerant asthma (ATA. METHODOLOGY/PRINCIPAL FINDINGS: Two-dimensional electrophoresis was adopted for differential display proteomics. Proteins were identified by liquid chromatography-tandem mass spectrometry (LC-MS. Western blotting and immunohistochemical staining were performed to compare the amount of fatty acid-binding protein 1 (FABP1 in the nasal polyps of patients with AERD and ATA. Fifteen proteins were significantly up- (seven spots or down-regulated in the nasal polyps of patients with AERD (n = 5 compared to those with ATA (n = 8. LC-MS revealed an increase in seven proteins expression and a decrease in eight proteins expression in patients with AERD compared to those with ATA (P = 0.003-0.045. FABP1-expression based on immunoblotting and immunohistochemical analysis was significantly higher in the nasal polyps of patients with AERD compared to that in patients with ATA. FABP1 was observed in epithelial, eosinophils, macrophages, and the smooth-muscle cells of blood vessels in the polyps. CONCLUSIONS/SIGNIFICANCE: Our results indicate that alterations in 15 proteins, including FABP1, may be related to the development of AERD.

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.

Full Text Available The pathobiology of allergic bronchial asthma is mediated by over-expressed T helper type 2 (Th2-biased immune responses to harmless environmental antigens, leading to airway inflammation and hyper-responsiveness. These Th2 responses are normally suppressed by functional T regulatory cells (Tregs, which maintain the airway tolerance. However, the Tregs activity is conceived to be compromised in allergic asthmatics. The curative therapy to counteract this immune dysregulation is not available so far, and to devise such a remedy is the current research impetus in allergic asthma therapeutics. One of the novel insights is to consider a Tregs-directed immunoregulatory therapy that could harness endogenous Tregs to redress the Th2/Tregs imbalance, thus enhancing the airway tolerance. Aspirin or acetylsalicylic acid (ASA is a prototype non-steroidal anti-inflammatory drug that possesses intriguing immunopharmacological attributes. For example, it can enhance the number or the frequency of functional Tregs, especially natural CD4+ CD25+ FoxP3+ Tregs, either directly or by inducing tolerogenic activity in dendritic cells (DCs. It is also considered to be beneficial for the induction of immunological tolerance in autoimmunity and graft rejection. This raises the question whether ASA, if exploited optimally, may be used to induce and harness endogenous Tregs activity for redressing Th2/Tregs imbalance in allergic asthma. In this paper, we hypothesise that ASA may help to counteract the underlying immune dysregulation in allergic asthma by promoting airway tolerance. Nevertheless, the future research in this regard will selectively need to be targeted to allergic asthma models, which are ASA insensitive, as ASA has some adverse background and is contraindicated in asthmatics who are sensitive to it.

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.

Colorectal cancer(CRC)is the third most common type of cancer worldwide.Screening measures are far from adequate and not widely available in resourcepoor settings.Primary prevention strategies therefore remain necessary to reduce the risk of developing CRC.Increasing evidence from epidemiological studies,randomized clinical trials and basic science supports the effectiveness of aspirin,as well as other non-steroidal anti-inflammatory drugs,for chemoprevention of several types of cancer,including CRC.This includes the prevention of adenoma recurrence and reduction of CRC incidence and mortality.The detectable benefit of daily low-dose aspirin(at least 75 mg),as used to prevent cardiovascular disease events,strongly suggests that its antiplatelet action is central to explaining its antitumor efficacy.Daily low-dose aspirin achieves complete and persistent inhibition of cyclooxygenase(COX)-1 in platelets(in pre-systemic circulation)while causing alimited and rapidly reversible inhibitory effect on COX-2and/or COX-1 expressed in nucleated cells.Aspirin has a short half-life in human circulation(about 20 minutes);nucleated cells have the ability to resynthesize acetylated COX isozymes within a few hours,while platelets do not.COX-independent mechanisms of aspirin have been suggested to explain its chemopreventive effects but this concept remains to be demonstrated in vivo at clinical doses.

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

Abundant epidemiological evidence indicates that regular and long term use of aspirin is associated with a significant reduction in the incidence of colorectal cancer (CRC). The long duration of aspirin needed to prevent CRC is believed to be due to inhibition of precursor lesions known as adenomas, whose recurrence is inhibited by aspirin in randomized trials. Aspirin intake has also been associated with a statistically significant improvement in patient survival after curative resection of ...

Asthma is one of the most common diseases of the lung. Asthma manifests with common, although often subjective and nonspecific, imaging features at radiography and high-resolution computed tomography. The primary role of imaging is not to make a diagnosis of asthma but to identify complications, such as allergic bronchopulmonary aspergillosis, or mimics of asthma, such as hypersensitivity pneumonitis. This article reviews the imaging features of asthma as well as common complications and mimics. PMID:27401624
The analgesic and antipyretic effect of the bark of willow has been known in Egypt and Greece for canturies. The modem era of salicylates starts with a letter sent 1758 by Reverend Edward Stone to The Royal Society in London. He described "an account of the success of the bark of willow in the cure of agues". His report. erroneously attributed to Edmond Stone. was published five years later. The active ingredient of willow bark. "salicine". was first isolated 1828 by Joseph Buchner, then by Henri Leroux, and also prepared from the oil of wintergreen (Gaultheria) and meadowsweet (Spirea ulmaria) by J. W. Lowig 1833. and called "Spirsäure", which was already pure acetylsalicylic acid. It was also synthetised 1853 by Ch. Gerhardt and finally 1897 in Bayer's laboratoires by Felix Hoffman, who also demonstrated its antiinflammatory efficacy. After two years of clinical trials with low doses, Bayer's management decided to start the productions and launched Aspirin as an analgetic worldwide in summer 1899. The first ASPIRIN ERA bagun. A completely new epoch started when J. N. Vane and Priscilla Piner demonstrated 1971 that the main mechanism of action of aspirin-like drugs is the inhibition of prostaglandin synthesis. In later studies the potency to inhibit platelet aggregation with small doses of aspirin (30-125 mg) was demonstrated. The Physicians'Health Study 1988 confirmed this effect: aspirin significantly reduced the risk of both, fatal and non-fatal myocardial infarction. and is now used in primary and secondary prevention of atherosclerosis. However the idea was not new: The use of salicylates and aspirin was throughly discussed more than 50 years ago: Paul C. Gibson published 1949 a well-documented case report on efficacy of aspirin in patients with angina, and Kl. Weber and P. Klein in Prague used Gibson's mixture successfully for patients with acute myocardial infarction (1951). Recently, the efficacy and security, the interactions and side-effects of low
BACKGROUND: 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-c...

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.

Sympathetic circulatory control is key to the rapid cardiovascular adjustments that occur within seconds of standing upright (orthostasis) and which are required for bipedal stance. Indeed, patients with ineffective sympathetic adrenergic vasoconstriction rapidly develop orthostatic hypotension, prohibiting effective upright activities. One speaks of orthostatic intolerance (OI) when signs, such as hypotension, and symptoms, such as lightheadedness, occur when upright and are relieved by recu...

In this issue of Scand J Nutr (pp 154-176) nine articles are published from the meeting Lactose intolerance revisited, February 1-2,2001, Stockholm, Sweden. Some further subjects of special interest were discussed during the meeting, and are reviewed in this short article.

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. PMID:26477616

Background: When lactose malabsorption gives rise to symptoms, the result is called 'lactose intolerance'. Although lactose intolerance is often bothersome for patients, once recognized it may be managed by simple dietary adjustments. However, diagnosing lactose intolerance is not straightforward, especially in primary care. Aim: To summarize available evidence on the diagnostic performance of gastrointestinal symptoms and self-reported milk (lactose) intolerance in primary care, and the rela...

Objective To review the advances of studies on clinical results of aspirin's chemopreventive effect against esophageal squamous cell carcinoma (ESCC) and evidences for mechanisms of the antitumoural effects of aspirin in experimental research.Data sources A comprehensive search of the PubMed literatures without restriction on the publication date was carried out using keywords such as aspirin and esophageal cancer.Study selection Articles associated with aspirin and esophageal cancer are analyzed.Results This review focuses on the current evidence for use of aspirin as a chemopreventive agent in ESCC.Aspirin is the most widely used among all nonsteroidal anti-inflammatory drugs (NSAIDs),which is cheap and acceptable to patients.Several observational results provide the further investigation of prevention and therapy of aspirin or similar drugs in esophageal cancer.Data from case control studies,cohort studies and randomized controlled trials (RCTs) also give some support of a beneficial role of aspirin on ESCC.Experimental data suggest that aspirin may prevent carcinogenesis of ESCC by favorably affecting proliferation,apoptosis,or other as yet unidentified growth-regulating processes.But the mechanism by which aspirin influence on esophageal squamous cell carcinoma needs further investigation.Conclusion A wealth of evidences ranging from clinical data to experimental results are building to suggest that aspirin has significant effects in reducing both the incidence and mortality of ESCC.

Aspirin 1200 mg was compared with placebo in a randomised, double-blind, crossover study in 15 patients with postoperative pain after removal of impacted lower third molars. Over a 5 h investigation period, patients reported significantly less pain (P less than 0.01) after treatment with aspirin, than after treatment with placebo. Peak concentrations of aspirin occurred at 15 min after dosage. Significant negative correlations were observed between plasma aspirin esterase activity and both AUC aspirin (r = -0.904, P less than 0.001) and AUC analgesia (r = -0.91, P less than 0.001). Similarly, a significant correlation was observed between AUC aspirin and AUC analgesia (r = 0.96, P less than 0.001). Evidence from this study would suggest that an individual's pain relief in postoperative dental pain is determined by the rate of aspirin hydrolysis to salicylate. PMID:6378231

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.

Many studies have been published in the last 10 years on the efficacy and safety of montelukast in asthma since this drug entered the market. Experimental studies, in vitro and in vivo, and clinical studies on large numbers of patients with asthma of different severity have clearly demonstrated that montelukast is able to modify the pathophysiological mechanisms of the disease, and to improve to some extent the clinical and functional manifestations of asthma. Studies of montelukast as monotherapy or in combination with other drugs, mainly inhaled corticosteroids (ICS), versus different comparator drugs have contributed to the positioning of montelukast in the different levels of asthma treatment, according to the Global Initiative for Asthma Guidelines. Montelukast may be used as monotherapy as an alternative to low-dose ICS (particularly in a step-down strategy) or in addition to ICS for improving clinical manifestations by an increase in anti-inflammatory effects and a sparing of corticosteroids. The heterogeneity of asthma has received a large amount of attention in the last few years in order to better tailor treatment according to the different clinical and biological phenotypes of asthma. Montelukast has proven to be particularly effective in exercise-induced asthma and in asthma associated with allergic rhinitis. Other phenotypes where montelukast is effective include asthma in obese patients, asthma in smokers, aspirin-induced asthma and viral-induced wheezing episodes. The safety profile of montelukast is very good, and the suspicions of increased risk of Churg-Strauss syndrome or suicide have not been confirmed. PMID:23251741

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).

Full Text Available The article contends that Euroscepticism is a fundamental variable for a good understanding of the support for new extreme right-wing party platforms in national elections among all Western European countries. Based on voting data for parties aligned with the new far right in European national elections, the article maps the growth of extreme right parties and tests the correlation between the support for intolerance and variables pertaining to economic and social issues, perceptions, and representations. The findings provide empirical evidence to confirm that the preference for intolerance is not based on material or economic dissatisfaction, since identity is the main focus of concerns and claims in the new political cleavage that supports the new extreme right.

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. PMID:26688272

None of the explanations proposed for the increase in paediatric asthma have been adequate. It is becoming apparent that the cause of the increase in asthma must be multi-factorial. Increasing attention has been focused on the role of lifestyle in the development of asthma. Lifestyle changes that have occurred in children are those in diet and decreased physical activity, with obesity being the product of these changes. The increase in asthma, obesity and a sedentary lifestyle have occurred together. However, a temporal relationship between asthma, obesity and decreased physical activity has not been determined in the paediatric literature. Limited data suggest that decreased physical activity could be playing a role in the aetiology of asthma independent of obesity. Furthermore, there has been substantial research on the benefits of exercise programmes for paediatric patients with asthma. Longitudinal trials monitoring physical activity, obesity and the development of asthma are needed. PMID:17098637

Asthma has long been considered a condition in which psychological factors have a role. As in many illnesses, psychological variables may affect outcome in asthma via their effects on treatment adherence and symptom reporting. Emerging evidence suggests that the relation between asthma and psychological factors may be more complex than that, however. Central cognitive processes may influence not only the interpretation of asthma symptoms but also the manifestation of measurable changes in im...

Editors' Summary Background. The proportion of children with asthma is thought to be increasing worldwide, and particularly among children that live in more developed countries. However, it is not clear why this is, since many different aspects of lifestyle and the environment have been linked with the onset of asthma. In Africa, asthma has typically been thought of as being very uncommon, and indeed in many African dialects there is no word for asthma or the symptoms, such as wheezing, that ...

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

Pancreatic cancer is a deadly disease with a dismal 5-year survival rate of <6%. The currently limited treatment options for pancreatic cancer underscore the need for novel chemopreventive and therapeutic agents. Accumulating evidence indicates that aspirin use is associated with a decreased risk of pancreatic cancer. However, the anticancer properties of aspirin are restricted by its gastrointestinal toxicity and its limited efficacy. Therefore, we developed phospho-aspirin (MDC-22), a novel derivative of aspirin, and evaluated its chemopreventive efficacy in preclinical models of pancreatic cancer. Phospho-aspirin inhibited the growth of human pancreatic cancer cell lines 8- to 12-fold more potently than aspirin; based on the 24-hour IC50 values. In a Panc-1 xenograft model, phospho-aspirin, at a dose of 100 mg/kg/d 5 times per week for 30 days, reduced tumor growth by 78% (P < 0.01 vs. vehicle control). Furthermore, phospho-aspirin prevented pancreatitis-accelerated acinar-to-ductal metaplasia in mice with activated Kras. In p48-Cre;Kras(G12D) mice, cerulein treatment (6 hourly injections two times per week for 3 weeks) led to a significant increase in ductal metaplasia, replacing the majority of the exocrine compartment. Administration of phospho-aspirin 100 mg/kg/day five times per week for 21 days (starting on the first day of cerulein injection) inhibited the acinar-to-ductal metaplasia, reducing it by 87% (P < 0.01, vs. cerulein-treated control). Phospho-aspirin appeared to be safe, with the animals showing no signs of toxicity during treatment. Mechanistically, phospho-aspirin inhibited EGFR activation in pancreatic cancer, an effect consistently observed in pancreatic cancer cells, primary acinar explants and in vivo In conclusion, our findings indicate that phospho-aspirin has strong anticancer efficacy in preclinical models of pancreatic cancer, warranting its further evaluation.

A 30-year-old woman and a 27-year-old man were found in a parked car after the man had telephoned his father to tell him of their suicide attempt. In spite of emergent hospitalization and intensive care, the woman died. Due to the possibility of his assisting her suicide, medicolegal autopsy and toxicological analysis were performed. On forensic autopsy, no external injuries or pathological findings were detected. The man recovered after 5 days of hospitalization. In spite of a negative toxicological screening test, the police investigation revealed that they may have taken 120 tablets (330 mg/tablet; 39,600 mg total dose) of aspirin (acetylsalicylic acid) orally; therefore, we analyzed the concentrations of acetylsalicylic acid and two kinds of metabolite in specimens obtained at autopsy and on emergent hospitalization using high performance liquid chromatography. Acetylsalicylic acid and/or the two metabolites were found in the woman's specimens. These substances were also present in the man's specimens. It is still unclear why the man survived in spite of what appeared to be a fatal aspirin overdose. It was very straightforward to diagnose aspirin poisoning in these cases; however, we have to be aware of poisoning by drugs which are not included in simple drug screening examinations.

Aspirin, one of the most commonly used anti-inflammatory drugs, has been recently reported to display multiple effects in the central nervous system (CNS), including neuroprotection and upregulation of ciliary neurotrophic factor (CNTF) expression in astrocytes. Although it was most recently reported that aspirin could promote the proliferation and differentiation of oligodendrocyte precursor cells (OPCs) after white matter lesion, the underlying mechanisms remain unclear. To dissect the effects of aspirin on oligodendroglial development and explore possible mechanisms, we here demonstrated the following: (i) in vitro treatment of aspirin on OPC cultures significantly increased the number of differentiated oligodendrocytes (OLs) but had no effect on the number of proliferative OPCs, indicating that aspirin can promote OPC differentiation but not proliferation; (ii) in vivo treatment of aspirin on neonatal (P3) rats for 4 days led to a nearly twofold increase in the expression of myelin basic protein (MBP), devoid of change in OPC proliferaion, in the corpus callosum (CC); (iii) finally, aspirin treatment increased the phosphorylation level of β-catenin and counteracted Wnt signaling pathway synergist QS11-induced suppression on OPC differentiation. Together, our data show that aspirin can directly target oligodendroglial lineage cells and promote their differentiation through inhibition of Wnt/β-catenin signaling pathway. These findings suggest that aspirin may be a novel candidate for the treatment of demyelinating diseases. PMID:26059811

Asthma is probably the most common serious medical disorder that may complicate pregnancy. A third of pregnant women with asthma will experience worsening of their symptoms, a third will see improvement of their symptoms and a third will see no change. The primary goal is to maintain optimal control of asthma for maternal health and well-being as well as fetal maturation. Vital patient education should cover the use of controller medication, avoidance of asthma triggers and early treatment of asthma exacerbations. Proper asthma management should ideally be started in the preconception period. Since smoking is probably the most modifiable risk factor of asthma, pregnant woman should avoid active and passive smoking. Acute asthma exacerbation during the first trimester is associated with an increased risk of congenital malformations. Poorly controlled asthma is associated with low birth weight, preeclampsia, and preterm birth. Medications used for asthma control in the non-pregnant population are generally the same in pregnancy with a few exceptions. Inhaled corticosteroids (ICS) are the preferred controller therapy. Budesonide is the preferred ICS. Long-acting B-agonists (LABA) are the preferred add-on therapy to medium to high dose ICS. Major triggers for asthma exacerbations during pregnancy are viral infections and ICS nonadherence. PMID:21858482

PURPOSE OF REVIEW: Obesity has significant impact on asthma incidence and manifestations. The purpose of the review is to discuss recent observations regarding the association between obesity and asthma focusing on underlying mechanisms, clinical presentation, response to therapy and effect of...... weight reduction. RECENT FINDINGS: Clinical and epidemiological studies indicate that obese patients with asthma may represent a unique phenotype, which is more difficult to control, less responsive to asthma medications and by that may have higher healthcare utilization. A number of common comorbidities...... have been linked to both obesity and asthma, and may, therefore, contribute to the obese-asthma phenotype. Furthermore, recently published studies indicate that even a modest weight reduction can improve clinical manifestations and outcome of asthma. SUMMARY: Compared with normal-weight patients, obese...

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. PMID:24879397

Full Text Available Recurrent stupor in children is an uncommon clinical problem with a wide differential diagnosis; inherited metabolic disorders account for a vast majority. We report a 9-year-old girl with recurrent episodes of stupor. Initial episode was treated as viral encephalitis and the second episode was managed as non-convulsive status epilepticus. Hyperammonemia was detected in the last episode. Metabolic work-up after dietary protein challenge revealed classical biochemical features of lysinuric protein intolerance. She was managed with protein-restricted diet, which resulted in marked neurological improvement. LPI is a rare inherited metabolic disorder due to membrane transport defect of cationic amino acids.

Heat stress profoundly and unanimously reduces orthostatic tolerance. This review aims to provide an overview of the numerous and multifactorial mechanisms by which this occurs in humans. Potential causal factors include changes in arterial and venous vascular resistance and blood distribution, and the modulation of cardiac output, all of which contribute to the inability to maintain cerebral perfusion during heat and orthostatic stress. A number of countermeasures have been established to improve orthostatic tolerance during heat stress, which alleviate heat stress induced central hypovolemia (e.g., volume expansion) and/or increase peripheral vascular resistance (e.g., skin cooling). Unfortunately, these countermeasures can often be cumbersome to use with populations prone to syncopal episodes. Identifying the mechanisms of inter-individual differences in orthostatic intolerance during heat stress has proven elusive, but could provide greater insights into the development of novel and personalized countermeasures for maintaining or improving orthostatic tolerance during heat stress. This development will be especially impactful in occuational settings and clinical situations that present with orthostatic intolerance and/or central hypovolemia. Such investigations should be considered of vital importance given the impending increased incidence of heat events, and associated cardiovascular challenges that are predicted to occur with the ensuing changes in climate.

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 (Prelationships 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.

Although histamine intolerance (HIT) is not very frequently encountered, it can have serious consequences. Food intolerance is a non allergic hypersensitivity to food that does not include the immune system even though the symptoms are similar to those of IgE-mediated allergic reactions. HIT apparently develops as a result of an impaired diamine oxidase (DAO) activity due to gastrointestinal disease or through DAO inhibition, as well as through a genetic predisposition which was proven in a number of patients. The intake of histamine-rich foods as well as alcohol or drugs which cause either the release of histamine or the blocking of DAO can lead to various disorders in many organs (gastrointestinal system, skin, lungs, cardiovascular system and brain), depending on the expression of histamine receptors. Dermatologic sequels can be rashes, itch, urticaria, angioedema, dermatitis, eczema and even acne, rosacea, psoriasis, and other. Recognizing the symptoms due to HIT is especially important in treating such patients. The significance of HIT in patients with atopic dermatitis in whom the benefit of a low histamine diet has been proven is becoming increasingly understood recently. Because of the possibility of symptoms affecting numerous organs, a detailed history of symptoms following the intake of histamine-rich foods or drugs that interfere with histamine metabolism is essential for making the diagnosis of HIT. Considering that such symptoms can be the result of multiple factors, the existence of HIT is usually underestimated, but considerable expectations are being made from future studies. PMID:23814966

Aspirin has public health potential to reduce the risk of ischaemic vascular events and sporadic cancer. One objection to the wider use of aspirin for primary prevention, however, is the undesirable effects of the medicine, which include increasing risk of bleeding and haemorrhagic stroke.

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.

Asthma can be affected by stress, anxiety, sadness, and suggestion, as well as by environmental irritants or allergens, exercise, and infection. It also is associated with an elevated prevalence of anxiety and depressive disorders. Asthma and these psychological states and traits may mutually potentiate each other through direct psychophysiological mediation, nonadherence to medical regimen, exposure to asthma triggers, and inaccuracy of asthma symptom perception. Defensiveness is associated with inaccurate perception of airway resistance and stress-related bronchoconstriction. Asthma education programs that teach about the nature of the disease, medications, and trigger avoidance tend to reduce asthma morbidity. Other promising psychological interventions as adjuncts to medical treatment include training in symptom perception, stress management, hypnosis, yoga, and several biofeedback procedures.

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...

Many markers of asthma morbidity have shown substantial increases over the past two decades, including family physician visits, use of anti-asthma medications, emergency room visits and hospital admissions. The reported prevalence of diagnosed asthma and of wheezing has increased, especially in children, with accompanying evidence of increased atopy and increased airway responsiveness. Allergen exposure and parental smoking are significant risk factors for childhood wheezing, whereas the infl...

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. PMID:25789542
High prevalence of asthma has been reported repeatedly among elite athletes, especially among endurance athletes. So many athletes used asthma drugs that the objective demonstration of bronchial hyperresponsiveness was required to obtain approval for their use in international sports until 2012 when the most used inhaled asthma drugs was allowed for free use, but with a maximum dose for inhaled β2-agonists. Several factors contribute to the development of asthma among the Olympians causing airways inflammation and bronchial hyper-responsiveness. PMID:26631837
