Prevalence of exercise induced bronchospasm in Kenyan school children: an urban-rural comparison. (1/234)

BACKGROUND: Higher rates of exercise induced bronchospasm (EIB) have been reported for urban than for rural African schoolchildren. The change from a traditional to a westernized lifestyle has been implicated. This study was undertaken to examine the impact of various features of urban living on the prevalence of EIB in Kenyan school children. METHODS: A total of 1226 children aged 8-17 years attending grade 4 at five randomly selected schools in Nairobi (urban) and five in Muranga district (rural) underwent an exercise challenge test. A respiratory health and home environment questionnaire was also administered to parents/guardians. This report is limited to 1071 children aged < or = 12 years. Prevalence rates of EIB for the two areas were compared and the differences analysed to model the respective contributions of personal characteristics, host and environmental factors implicated in childhood asthma. RESULTS: A fall in forced expiratory volume in one second (FEV1) after exercise of > or = 10% occurred in 22.9% of urban children and 13.2% of rural children (OR 1.96, 95% CI 1.41 to 2.71). The OR decreased to 1.65 (95% CI 1.10 to 2.47) after accounting for age, sex, and host factors (a family history of asthma and breast feeding for less than six months), and to 1.21 (95% CI 0.69 to 2.11) after further adjustment for environmental factors (parental education, use of biomass fuel and kerosene for cooking, and exposure to motor vehicle fumes). CONCLUSIONS: The EIB rates in this study are higher than any other reported for African children, even using more rigorous criteria for EIB. The study findings support a view which is gaining increasing credence that the increase in prevalence of childhood asthma associated with urbanisation is the consequence of various harmful environmental exposures acting on increasingly susceptible populations.  (+info)

Evaluation of pulmonary resistance and maximal expiratory flow measurements during exercise in humans. (2/234)

To evaluate methods used to document changes in airway function during and after exercise, we studied nine subjects with exercise-induced asthma and five subjects without asthma. Airway function was assessed from measurements of pulmonary resistance (RL) and forced expiratory vital capacity maneuvers. In the asthmatic subjects, forced expiratory volume in 1 s (FEV1) fell 24 +/- 14% and RL increased 176 +/- 153% after exercise, whereas normal subjects experienced no change in airway function (RL -3 +/- 8% and FEV1 -4 +/- 5%). During exercise, there was a tendency for FEV1 to increase in the asthmatic subjects but not in the normal subjects. RL, however, showed a slight increase during exercise in both groups. Changes in lung volumes encountered during exercise were small and had no consistent effect on RL. The small increases in RL during exercise could be explained by the nonlinearity of the pressure-flow relationship and the increased tidal breathing flows associated with exercise. In the asthmatic subjects, a deep inspiration (DI) caused a small, significant, transient decrease in RL 15 min after exercise. There was no change in RL in response to DI during exercise in either asthmatic or nonasthmatic subjects. When percent changes in RL and FEV1 during and after exercise were compared, there was close agreement between the two measurements of change in airway function. In the groups of normal and mildly asthmatic subjects, we conclude that changes in lung volume and DIs had no influence on RL during exercise. Increases in tidal breathing flows had only minor influence on measurements of RL during exercise. Furthermore, changes in RL and in FEV1 produce equivalent indexes of the variations in airway function during and after exercise.  (+info)

Reduction of exercise-induced asthma in children by short, repeated warm ups. (3/234)

AIM: To study the effect of a warm up schedule on exercise-induced asthma in asthmatic children to enable them to engage in asthmogenic activities. METHOD: In the first study, peak flows during and after three short, repeated warm up schedules (SRWU 1, 2, and 3), identical in form but differing in intensity, were compared in 16 asthmatic children. In the second study the efficiency of the best of these SRWU schedules was tested on 30 young asthmatic children. Children performed on different days a 7 minute run alone (EX1) or the same run after an SRWU (EX2). RESULTS: The second study showed that for most children (24/30) the fall in peak flow after EX2 was less than that after EX1. The percentage fall in peak flow after EX2 was significantly correlated with the percentage change in peak flow induced by SRWU2 (r = 0.68). The children were divided into three subgroups according to the change in peak flow after SRWU2: (G1: increase in peak flow; G2: < 15% fall in peak flow; G3: > 15% fall in peak flow). Only the children in the G3 subgroup did not show any gain in peak flow after EX2 compared with EX1. CONCLUSION: The alteration in peak flow at the end of the SRWU period was a good predictor of the occurrence of bronchoconstriction after EX2. An SRWU reduced the decrease in peak flow for most of the children (24/30) in this series, thus reducing subsequent post-exercise deep bronchoconstriction.  (+info)

Bronchoscopy and bronchoalveolar lavage findings in cross-country skiers with and without "ski asthma". (4/234)

Bronchial hyperresponsiveness to methacholine with asthma-like symptoms ("ski asthma") is frequent in elite cross-country skiers. To further the understanding of "ski asthma", 10 nonasthmatic, nonatopic controls and 30 adolescent elite skiers were investigated by bronchoscopy and bronchoalveolar lavage (BAL). Nine skiers were atopic without allergy symptoms. Compared with controls, the macroscopic inflammatory index in the proximal airways in skiers was three-fold greater (median (interquartile range) 3.0 (2.0-5.0) versus 1.0 (0.8-2.3), p=0.008). In the BAL fluid, skiers had significantly greater total cell (p<0.05) and percentage lymphocyte (p<0.01) and mast cell counts (p<0.05). Neutrophil and eosinophil counts were not significantly different and eosinophil cationic protein was not detected. Tumour necrosis factor-alpha and myeloperoxidase were detected in 12 (40%) and six (20%) skiers, respectively. In skiers with ski asthma, the inflammatory index was greater than in nonasthmatic skiers. Lymphocyte subtypes and activation markers, and concentration of albumin, fibronectin and hyaluronan were not different from those in controls. Cross-country skiers have a minor to moderate degree of macroscopic inflammation in the proximal airways at bronchoscopy and a bronchoalveolar lavage fluid profile which differs in several respects from healthy controls. Skiers with ski asthma tend to show even higher degrees of bronchial inflammation.  (+info)

Airway obstruction during exercise and isocapnic hyperventilation in asthmatic subjects. (5/234)

We compared pulmonary mechanics measured during long-term exercise (LTX = 20 min) with long-term isocapnic hyperventilation (LTIH = 20 min) in the same asthmatic individuals (n = 6). Peak expiratory flow (PEF) and forced expiratory volume in 1 s (FEV(1)) decreased during LTX (-19.7 and -22.0%, respectively) and during LTIH (-6.66 and 10. 9%, respectively). In contrast, inspiratory pulmonary resistance (RL(I)) was elevated during LTX (57.6%) but not during LTIH (9.62%). As expected, airway function deteriorated post-LTX and post-LTIH (FEV(1) = -30.2 and -21.2%; RL(I) = 111.8 and 86.5%, respectively). We conclude that the degree of airway obstruction observed during LTX is of a greater magnitude than that observed during LTIH. Both modes of hyperpnea induced similar levels of airway obstruction in the posthyperpnea period. However, the greater airway obstruction during LTX suggests that a different process may be responsible for the changes in airway function during and after the two modes of hyperpnea. This finding raises questions about the equivalency of LTIH and LTX in the study of airway function during exercise-induced asthma.  (+info)

Surfactant function affected by airway inflammation and cooling: possible impact on exercise-induced asthma. (6/234)

Pulmonary surfactant maintains patency of narrow conducting airways. An inflammation, with a leakage of plasma proteins into the airway lumen, causes surfactant to lose some of this ability. Will a lowering of temperature aggravate the deteriorating effect of an inflammation? Calf lung surfactant extract (CLSE) with proteins added was studied with a capillary surfactometer (CS) at temperatures of 25-42 degrees C. BALB/c mice were infected with respiratory syncytial virus (RSV). Six days later the lungs were lavaged and the surfactant in the lavage fluid was studied with the CS at temperatures of 25-42 degrees C. Lavage fluid from allergen challenged asthmatics was examined for its content of surfactant inhibitors at reduced temperatures. It was shown that CLSE with proteins gradually lost its ability to maintain patency as the temperature was lowered. Lavage fluid from the RSV infected mice showed a similar dysfunction at low temperatures. Lavage fluid from the airways of human asthmatics, when challenged with antigen but not with saline, contained agents inhibiting surface activity, particularly at reduced temperatures. Airway inflammation causes surfactant to lose its ability to maintain patency, particularly as the temperature is reduced. That might be a reason for the increased airway resistance observed in asthma patients hyperventilating in cold weather.  (+info)

Specific and nonspecific obstructive lung disease in childhood: causes of changes in the prevalence of asthma. (7/234)

Reversible airway obstruction in childhood includes two major groups of patients: those with recurrent wheezing following bronchiolitis in early childhood, and those with allergic asthma, which represents an increasingly large proportion of cases through the school years. Over the last 40 years of the 20th century, allergic asthma has increased in many countries and in relation to several different allergens. Although this increase has differed in magnitude in different countries and also in the social groups most affected, it has had several features in common. The increase generally started between 1960 and 1970, has been progressive since then, and has continued into the 1990s without a defined peak. Among children 5-18 years of age, the increase has predominantly been among allergic individuals. Theories about the causes of the increase in asthma have focused on two scenarios: a) that changes in houses combined with increased time spent indoors have increased exposure to relevant allergens, or b) that changes in diet, antibiotic use, immunizations, and the pattern of infections in childhood have led to a change in immune responsiveness such that a larger section of the population makes T(H)2, rather than T(H)1 responses including IgE antibodies to inhalant allergens. There are, however, problems with each of these theories and, in particular, none of the proposed changes can explain the progressive nature of the increase over 40 years. The fact that the change in asthma has much in common with epidemic increase in diseases such as Type II diabetes or obesity suggests that similar factors could be involved. Several lines of evidence are reviewed that suggest that the decline in physical activity of children, particularly those living in poverty in the United States, could have contributed to the rise in asthma. The hypothesis would be that the progressive loss of a lung-specific protective effect against wheezing has allowed allergic children to develop symptomatic asthma. What is clear is that current theories do not provide either an adequate explanation of the increase or a practical approach to reversing the current trend.  (+info)

Nedocromil sodium in the treatment of exercise-induced asthma: a meta-analysis. (8/234)

Exercise-induced asthma (or bronchoconstriction) afflicts millions of people worldwide. While generally self-limiting, it can hinder performance and reduce activity levels, thus it is an important condition to diagnose and treat. The objective of this review was to assess the prophylactic effect of a single dose of nedocromil sodium on exercise-induced asthma. The Cochrane Airways Group trials register, the Cochrane Controlled Trials Register, Current Contents, reference lists of relevant articles, review articles and textbooks were searched for randomized trials comparing a single dose of nedocromil to placebo to prevent exercise-induced asthma in people >6 yrs of age. Authors and the drug manufacturer were contacted for additional trials. Trial quality assessments and data extraction were conducted independently by two reviewers. Authors were contacted when possible. Twenty trials were included. All were rated as having good methodological quality. Nedocromil inhibited bronchoconstriction in all age groups. The pooled weighted mean difference for the maximum percentage fall in forced expiratory volume in one second was 15.6%, (95% confidence interval (95% CI): 13.2-18.1) and for the peak expiratory flow was 15.0% (95% CI: 8.3-21.6). These differences are both statistically and clinically significant. After nedocromil the time to recover normal lung function was <10 min compared to >30 min with placebo. Nedocromil had a greater effect on people with a fall in lung function of >30% from baseline. There were no significant adverse effects reported with this short-term use. In conclusion, Nedocromil taken before exercise appears to reduce the severity and duration of exercise-induced bronchoconstriction. This effect appears to be more pronounced as severity increases.  (+info)

BACKGROUND: The prevalence of exercise-induced bronchoconstriction among British children by ethnicity has not been studied. METHODS: Peak expiratory flow rate (PEFR) was measured before and after an exercise challenge test using a cycle ergometer in 593 nine year olds from Scottish and inner city English schools. Logistic regression analysis was carried out to assess the association between changes in PEFR with exercise by reported asthma, ethnicity, and sex. RESULTS: The probability of exercise-induced bronchoconstriction was greater among the asthmatics than in either the children without asthma attacks or wheeze, or in the children with only wheeze (p , 0.01). Asian children were 3.6 times more likely to have exercise-induced bronchoconstriction than white inner city children, and also were more likely to have exercise-induced bronchoconstriction than those from the other ethnic groups (p , 0.01). CONCLUSION: Exercise challenge can assess the prevalence of asthma in the community and detect ...
Its been estimated that nine out of 10 chronic asthma sufferers, and four of 10 individuals with allergic rhinitis or atopic dermatitis, will feel the effects of exercise-induced asthma. Symptoms can include chest tightness, coughing, shortness of breath, and fatigue. There is hope for sufferers of this condition, however: Researchers at the University of Indiana have found that fish oil may reduce the severity of exercise-induced asthma in athletes. Subjects who consumed fish oil capsules daily for three weeks (approximately 5.4 grams of fish oil per day) showed improved postexercise pulmonary function and reduced symptoms of exercise-induced asthma compared to control subjects who received no fish oil supplementation. Good dietary sources of fish oil include herring, albacore tuna, salmon, mackerel, sardines and anchovies. And if you dont have the time (or palate) to fit fish into your regular diet, you can always get the benefits of fish oil from a regular supplement. Ask your chiropractor ...
Lets face it: exercising in the winter sucks. Running outside in freezing temperatures is a chore, the treadmill and stationary bike get boring in a hurry, and exiting the gym after a shower leaves you with frozen, crunchy hair.. But for the millions of people with exercise-induced asthma, those annoyances are the least of their problems. The cold, dry winter air is a major trigger that constricts their airways and makes breathing difficult. The end result: shortness of breath, coughing, wheezing, a tight chest, and decreased endurance.. Exercise-induced asthma-or, more correctly, exercise-induced bronchospasm, or EIB-affects roughly 8 in 10 Americans with a diagnosis of asthma and 1 in 10 Americans in the general population, although these numbers may be higher, given that many people are not aware that they have the condition, especially if they have a milder case..

To the Editors: The report by Kraus and colleagues (1) documenting the frequent occurrence of symptomatic gastroesophageal reflux in runners raises the hypothesis that this association might contribute to the pathophysiology of another exercise-related condition, exercise-induced asthma.. Exercise has long been recognized as a stimulus of airway obstruction in patients with asthma. Although several studies have shown the etiologic importance of exercise-induced airway heat and water loss to subsequent bronehoconstriction, these factors may not entirely explain the association. It has been shown that both the intensity and type of exercise may determine the severity of exercise-induced asthma (2). Among the ...

Vitamin C consumption may have a beneficial effect on respiratory symptoms encountered after exercise, according to a meta-analysis published in the journal BMJ Open by Dr Harri Hemila from the University of Helsinki. Exercise-induced bronchoconstriction (EIB) is a temporary narrowing of the airway which can occur during or after exercise, resulting in a decline in forced expiratory volume (FEV) and affecting around 10% of the general population to about 50% in some fields of competitive athletics. Formerly, this condition was called exercise-induced asthma. Symptoms include coughing, wheezing and shortness of breath. Hemila identified three suitable trials (Schachter and Schlesinger, Cohen et al and Tecklenburg et al), through Medline and Scopus. The studies were all randomised, double blind and placebo controlled trials and involved a total of 40 participants who each consumed between 0.5g and 2 g of vitamin C before exercise according to the individual study. Despite the differences in age of ...
Exercise-induced asthma, or E.I.A., occurs when the airways narrow as a result of exercise. The preferred term for this condition is exercise-induced bronchoconstriction (EIB); exercise does not cause asthma, but is frequently an asthma trigger. It might be expected that people with E.I.B. would present with shortness of breath, and/or an elevated respiratory rate and wheezing, consistent with an asthma attack. However, many will present with decreased stamina, or difficulty in recovering from exertion compared to team members, or paroxysmal coughing from an irritable airway. Similarly, examination may reveal wheezing and prolonged expiratory phase, or may be quite normal. Consequently, a potential for under-diagnosis exists. Measurement of airflow, such as peak expiratory flow rates, which can be done inexpensively on the track or sideline, may prove helpful. While the potential triggering events for E.I.B. are well recognized, the underlying pathogenesis is poorly understood. It usually occurs ...

Exercise-induced laryngeal obstruction (EILO) is one of many different causes for adolescents to experience dyspnoea during exercise. Objective exercise-testing with continuous video laryngoscopy is crucial for a correct diagnosis since it is difficult to differentiate EILO from other exercise related conditions in the airways only on the symptomatology. The main symptom in EILO is inspiratory stridor arising from an obstruction at the laryngeal level during ongoing exercise which quickly resolves after the exercise has stopped. EILO is often misdiagnosed as exercise-induced bronchoconstriction (EIB), which is obstruction in the peripheral airways that typically arises after cessation of exercise.. From a previous survey investigating self-reported exercise-induced dyspnoea in all 12-13-year-old adolescents in Uppsala (n=3,838, response rate 60.2%) a subset of 150 randomly selected adolescents (103 with dyspnoea and 47 controls) performed standardized treadmill exercise-tests for EIB and ...

Objective: to compare specificity and sensitivity of the metacholine challenge test (MCT) and exercise challenge test for the diagnosis of bronchial asthma in athletes.. Methods: 19 athletes (12 M/7 F, mean age 24.8±3.6 yrs) with respiratory symptoms were studied. Lung function with assessment of reversibility to salbutamol (n=19), MCT (n=19) and exercise test on a bicycle ergometer (n=17) were performed. The specificity and sensitivity of the MCT and exercise test were evaluated.. Results: Significant reversibility to salbutamol was found in 5 athletes. The fall in forced expiratory volume in one second (FEV1) following the metacholine inhalation (,8 mg/ml) was more than 20% in 10 athletes. The MCT showed high specificity (100%), high sensitivity (100%) and negative predictive value (100%). At the moderate cut-off value (,4 mg/ml), the MCT had a more low sensitivity (80%) and negative predictive value (82%). Exercise challenge test was negative in all the athletes. The maximal fall in FEV1 ...
Exercise-induced bronchospasm (EIB) can be prevented in everyone. Exercise is just as important for people with asthma as it is for others. However, breathing relatively cold air triggers bronchospasm in most people with asthma. The airways become dry and they respond by narrowing (bronchospasm). Symptoms of cough, wheezing, chest tightness, and/or shortness of breath start about 5 minutes after the exercise stops and last for about 45 minutes (unless treated by using a rescue inhaler like albuterol). About 10% of athletes, even those who successfully compete in the Olympics, have EIB. The good news is that it can almost always be prevented. Strenuous exercise in cold air is the most potent EIB stimulus, such as cross-country skiing. Swimming rarely causes EIB since you are breathing warm and humid air while swimming. When walking in the winter cold, keep your nose open (by treating rhinitis, perhaps using nasal lavage) so that you can breathe through it. Breathing through your nose wa. ...

Asthma is one of the most common illnesses, affecting 13% of Canadians aged 5 to 19 years. Since the body uses the omega-3 fatty acid DHA (docosahexaenoic acid) found in fish to produce anti-inflammatory compounds, it is believed that fish oils can benefit asthma sufferers. In fact, studies show that in populations eating large amounts of fish, asthma rates are lower.. In a recent study, researchers from Indiana University found that fish oils could significantly reduce the severity of exercise-induced asthma (exercise-induced bronchoconstriction, or EIB). EIB occurs in 80 to 90% of people with asthma and in about 11% of people without asthma.. In this double-blind study, 10 elite athletes with EIB and 10 elite athletes without EIB received either fish oils or a placebo daily for three weeks. When measured at 15 minutes after exercise, test results showed only a 3% decrease in pulmonary function for the fish oils group, compared to a 14.5% decrease for the placebo group.

Asthma is a long-term condition causing swelling and narrowing of the airways. The muscles around the airways tighten and extra mucus is produced. These changes make it more difficult to move air in and out of the lungs. Triggers are things that cause asthma flare-ups and worsen symptoms. Triggers may be dust, pollen, pets, infections, cold weather, smoke, air pollution, and exercise. Exercise is a common trigger for many people with asthma. For some, exercise, and other things, cause asthma symptoms. For others, asthma symptoms only happen with exercise or physical activity. In either case, the term to describe the condition is exercise-induced bronchoconstriction or EIB. (It used to be called exercise-induced asthma.) It means that exercise causes the airways or bronchi to narrow or constrict. Exercise is important for overall good health and for keeping the lungs and muscles involved in breathing strong.

AU - Morton, Alan. AU - Fitch, Ken. PY - 2001. Y1 - 2001. N2 - Purpose: As new delivery devices and formulations are being introduced for drugs given by inhalation, there is a need to evaluate their equivalence with old preparations. One way to do this is to investigate their equivalence in protecting from exercise-induced asthma (EIA). Methods: We used a protocol for EIA to compare the protective effect of salbutamol delivered by the pressurised metered dose inhaler (pMDI) and the new Diskus dry powder device. Twenty-seven asthmatic subjects with moderately severe EIA completed an exercise test on four separate days at two study centers. Exercise was performed by cycling for 8 min while inhaling dry air (0% RH, 20-24 degreesC). The target workload in W was predicted as (53.76 x predicted FEV1) - 11.07 ...
If you are experiencing coughing, wheezing or have chest pain or tightness during or after exercise, you need to see your doctor. "People dont know they have exercise-induced asthma because they think its normal for them to feel that way post-exercise," states Dr. Gheller-Rigoni. "Many people who have this condition are in very good physical shape, but they feel like they are short on endurance, which is not the case." To receive proper diagnosis, your doctor will ask you for a detailed history of your signs and symptoms. Writing down when and where you are when you are experiencing these symptoms can be helpful to your physician. If you already suffer from asthma and have an inhaler, your doctor may want you to bring it in to make sure you are using it correctly and to verify the inhaler has been primed. Your doctor may do other tests to make sure your symptoms arent being caused by something else such as heart disease, lung disorders, or other allergies. Lung function tests may also be ...

Remember that when someone is having an attack, theyll almost always find it easier to breathe while sitting up than lying down. So dont make the mistake of getting them to lie down -- settle them into a sitting position and make them as comfortable as possible. Beta-adrenergic drugs are medications that relax smooth muscle and widen the airways. They are commonly used for relieving sudden attacks of asthma and preventing exercise-induced asthma.___________________Get Your 24 Hour Yeast Infection Cure ...
When a child experiences coughing, wheezing and chest pains while engaged in physical activity, the default conclusion is that the child must be suffering from exercise-induced asthma (EIA). However, there are several other explanations for wheezing in pediatric patients often overlooked and therefore, left untreated. A featured science session at the 55th Annual Meeting of the American College of Sports Medicine (ACSM) addressed the issue of pediatric wheezing and the possible diagnoses beyond EIA ...
Ashton will forfeit $169,185 during the suspension.. The 23-year-old Ashton released a statement regarding the suspension, claiming he suffered an asthmatic spasm in late August during summer training and was given an inhaler by another player. Ashton kept the inhaler and used it a second time early in training camp after another asthma attack. "Unfortunately, I incorrectly assumed that there were no problems associated with the use of this inhaler and I used it without checking to see whether its contents were permissible under the NHL/NHLPA Performance Enhancing Substances Program," Ashton said in his statement.. "I now recognize that I ingested Clenbuterol, a prohibited substance, through the inhaler. However, at no time was I seeking to gain an athletic advantage or to knowingly violate the terms of the program. I used the inhaler in response to exercise-induced asthma, a condition that my doctor with the Toronto Maple Leafs has since diagnosed and he has prescribed me with an ...
To the Editor-We thank Dr Hofmeister for highlighting an emerging area in allergy prevention. The evidence for the association of lack of physical activity with allergic diseases in both adults and children is interesting1 2 3 4 but the results were obtained mainly through population-based cross-sectional studies. Although there may be a true association between a decrease in physical activity and more atopic tendencies, one cannot exclude reverse causality of decreased physical activity in these groups of atopic patients, for instance an exacerbation of eczema after sweating; heat and dermatographic stimulation; or shortness of breath in exercise-induced asthma. It is essential now to conduct prospective studies to test the hypothesis when some of the confounding factors that may discourage atopic patients to exercise are tightly controlled. Of course, we agree that adequate exercise helps to control body weight that is known to be associated with asthma and eczema as mentioned in the ...

For me the doctor wanted to see me very quickly to rule out a heart attack or heart problem or other super-dire thing; after that they ran some tests over a few visits to nail it down to allergy-induced asthma that only manifests during exertion (or exercise-induced asthma that only manifests during allergies?) and try a few different therapies. So for me there was an initial flurry of oh good, you wont die of this and then a more leisurely investigation, particularly getting me in to breathe in the meter during different weather/allergens to get some good data, and giving me a home (less-accurate) meter to chart myself during different things, to help nail it down ...
Forty-seven-year-old Malvern Skip Monaghan Jr. had logged around 630 hours by August 2001. The last time he went up was when he flew the Cessna 182 from St. Simons Island, Georgia, back home to Suwanee, Georgia, three weeks before he visited the doctor. Lately his throat had been getting tight, but he wrote it off to exercise-induced asthma.

Exercise-induced bronchoconstriction (EIB) is the most common chronic condition in elite athletes [1]. Especially endurance athletes who reach high ventilation in cold, dry air on a regular basis are susceptible to EIB [1, 2]. A study using a canine model highlighted the negative effect of dry air on the airways as it leads to airway inflammation and airway remodeling [3]. In humans this find has been confirmed in bronchial biopsies from competitive elite skiers, showing signs of eosinophilic and neutrophilic airway inflammation in the lungs, similar to those seen in asthma [4].. In elite speed skaters intense training may cause thoracic pain and cause EIB [5]. For this reason many speed skaters use a roll-collar in training to warm and humidify inhaled air. Beuther et al. already showed that warming the inhaled air can reduce EIB [6]. In competition, due to aerodynamics, this method cannot be used. In an effort to reduce EIB and thoracic pain, international professional speed skaters nowadays ...
BACKGROUND: Children who suffer from recurrent wheezy episodes are often promptly classified as asthmatic. The aim of this study was to evaluate a population of mild wheezy children with repeatedly normal spirometric tests at rest for atopy, bronchial hyperresponsiveness, and peak expiratory flow variability. METHODS: Thirty nine children aged 6-16 years with 1-12 wheezy attacks during the previous year were recruited from a community paediatric primary health care clinic serving an urban Israeli population. The conditions for inclusion were a physician-diagnosed wheeze on auscultation and normal spirometric tests at rest on at least three occasions. Evaluation included skin prick tests for atopy and a physician-completed questionnaire. In addition, two tests of bronchial hyperresponsiveness (BHR) were performed--namely, exercise-induced bronchospasm and inhaled methacholine hyperresponsiveness--as well as diurnal variability of peak expiratory flow (PV). RESULTS: One or more tests of BHR/PV ...

Asthma control in adolescents: role of leukotriene inhibitors Stavroula Giavi, Nikolaos G PapadopoulosAllergy Department, Second Pediatric Clinic, University of Athens, Athens, GreeceAbstract: Asthma is a chronic inflammatory disease of the airways and is a big burden worldwide. It affects both children and adults, but it is insufficiently studied in adolescents, although this age group has important peculiarities and is challenging to treat, due to, but not exclusively because of, lack of adherence to treatment instructions. Evidence-based guidelines for the treatment of asthma targeting specifically adolescents are lacking, due to the fact that most studies are conducted either on children or in adults. Exercise-induced asthma occurs commonly in adolescents, leading to impaired physical activity. This review describes current treatment options for asthma in adolescents, focusing on leukotriene receptor antagonists, both as a monotherapy and as an add-on therapy for optimal asthma control.Keywords:

Asthma is a long-term condition causing swelling and narrowing of the airways. The muscles around the airways tighten and extra mucus is produced. These changes make it more difficult to move air in and out of the lungs. Triggers are things that cause asthma flare-ups and worsen symptoms. Triggers may be dust, pollen, pets, infections, cold weather, smoke, air pollution, and exercise.. Exercise is a common trigger for many people with asthma. For some, exercise, and other things, cause asthma symptoms. For others, asthma symptoms only occur with exercise or physical activity. In either case, the term to describe the condition is exercised-induced bronchoconstriction or EIB. (It used to be called exercise-induced asthma.) It means that exercise causes the airways or bronchi to narrow on constrict.. Exercise is important for overall good health and for keeping the lungs and muscles involved in breathing strong. Your body needs exercise. Make sure you work with your health care provider to do it ...

The study of the effects of antioxidant nutritional status with allergic rhinitis (AR) in Korean schoolchildren aged 6-12 years, in a total of 4,554 children in Seoul, Korea, showed a positive effect of Vitamin C intake negatively associated with an increased risk of AR symptoms(1). According to the Rabin Medical Center, vitamin C also enhanced the protective effect on the hyperreactive airways of patients with exercise-induced asthma (EIA)(2). Oxidative stress mediated by reactive oxygen species is known to contribute to the inflammatory process of bronchial asthma. According to Dr. Ruprai RK., in the study of the oxidative stress plasma malondialdehyde and ascorbic acid (Vitamin C) showed an oxidative imbalance in asthmatic patients and antioxidant supply may have a beneficial impact on the free radical induced injury and improvement of respiratory reserve in Asthmatics(3)(4). In Saudi asthmatic patients, King Saud University study, exhibition of oxidative stress and defective antioxidant ...
The exact cause of asthma is not completely known. It is believed to be partially inherited, but it also involves many other environmental, infectious, and chemical factors.. After a child is exposed to a certain trigger, the body releases histamine and other agents that can cause inflammation in your childs airways. The body also releases other factors that can cause the muscles of the airways to tighten, or become smaller. There is also an increase in mucus production that may clog the airways.. Some children have exercise-induced asthma, which is caused by varying degrees of exercise. Symptoms can occur during, or shortly after, exercise. Each child has different triggers that cause the asthma to worsen. You should discuss this with your childs doctor.. The changes that occur in asthma are believed to happen in two phases:. ...

CHEMICAL ecology. Abstract:Despite the progress that has been made in the treatment of asthma, the prevalence and burden of this diseasehas continued to increase. Exercise is a powerful trigger of asthma symptoms and reversible airflow obstructionand may result in the avoidance of physical activity by patients with asthma, resulting in detrimentalconsequences to their health. Approximately 90% of patients with asthma are hyperresponsive to exercise andexperience exercise-induced bronchoconstriction (EIB). While pharmacologic treatment of asthma is usuallyhighly effective, medications often have significant side-effects or exhibit tachyphylaxis. Alternative therapiesfor treatment (complementary medicine) that reduce the dose requirements of pharmacologic interventions wouldbe beneficial, and could potentially reduce the public health burden of this disease. There is accumulating evidencethat dietary modification has potential to influence the severity of asthma and reduce the prevalence ...
A series of agents were examined to determine whether responses to hyperosmolarity could involve a mediator known or postulated to exist in other organ systems or processes. Responses of vascular muscle to endothelium-derived hyperpolarizing factor are inhibited by the cytochrome P450 inhibitor proadifen (SKF525A; Eckman et al., 1998). This agent, however, did not antagonize responses to d-M or hyperosmolar NaCl, suggesting that arachidonic acid epoxides are not mediators of the response. Because histamine and leukotrienes are viewed to be important mediators in exercise-induced asthma, the effects of the H1-histamine receptor antagonist diphenhydramine and the CysLT1-receptor antagonist MK 571 were examined, even though there is little likelihood that these contractile substances would mediate relaxation. These blockers had no effect, suggesting that these substances do not serve as intermediaries of the response to hyperosmolar solution, at least in vitro.. Application of hyperosmolar solution ...

Packing: 1kg/bag. Salbutamol Description:. Salbutamol, also known as albuterol and marketed as Ventolin among other names,is a medication that opens up the medium and large airways in the lungs.It is used to treat asthma, exercise-induced bronchoconstriction, and chronic obstructive pulmonary disease (COPD). It may also be used to treat high blood potassium levels.It is usually used by inhaler or nebulizer but is also available as a pill and intravenous solution.Onset of action of the inhaled version is typically within 15 minutes and lasts for two to six hours.. Common side effects include shakiness, headache, fast heart rate, dizziness, and feeling anxious. Serious side effects may include worsening bronchospasm, irregular heartbeat, and low blood potassium levels. It can be used during pregnancy and breastfeeding, but safety is not entirely clear. Salbutamol is a short-acting β2 adrenergic receptor agonist which works by causing airway smooth muscles to relax.. Salbutamol was first made in ...
Next Professor Mady Hornig from Columbia University, USA, gave a detailed and highly informative account of her work towards developing blood biomarkers. She explained how immunity and gut microbiota can be linked to the brain, its functioning and mood. She talked about the epigenetic changes that can occur in the microbiome during a persons lifetime and the link to serotonin production. She also talked about measuring blood molecules such as cytokines before and after an exercise challenge in ME patients, and comparing these changes to healthy controls. These cytokines being the most promising as potential biomarkers. Although much of what she described cannot be simply summarised, the audience was left with a strong feeling that Professor Hornig is now working determinedly to solve the biochemical riddles produced by ME. ...

I improved it 33 percent. Well it still doesnt mean it has any reasonable chance of success at any point. Its an improvement off a number that had zero chance of success. And so you have to view their position from that standpoint. When we came in (August 14), we came in with a real offer from the beginning, what I had hoped for is a real negotiation. So far we havent had it ...

  • Following a careful history and physical examination, children performed pulmonary function tests before, then 5 and 15 minutes after a standardised treadmill exercise test. (bmj.com)
  • Certain environmental conditions such as cold air, high or low humidity, air pollution or elevated air allergens may increase exercise-induced asthma. (boystownpediatrics.org)
  • We hypothesize that the inhibitory effects of exercise on gastric acid secretion decreases the digestion of oral allergens and preserves structural integrity, thereby allowing continued systemic absorption of the allergen whether it be profilins, lipid transfer proteins, or other antigenic determinants. (biomedcentral.com)
  • Asthma is associated with exposure to indoor allergens. (wikipedia.org)
  • Primary causes are believed to be gastroesophageal reflux disease (GERD), extra-esophageal reflux (EERD), exposure to inhaled allergens, post-nasal drip, exercise, or neurological conditions that can cause difficulty inhaling only during waking. (wikipedia.org)
  • The mechanisms behind allergic asthma-i.e., asthma resulting from an immune response to inhaled allergens-are the best understood of the causal factors. (wikipedia.org)
  • Another allergen is urushiol, a resin produced by poison ivy and poison oak, which causes the skin rash condition known as urushiol-induced contact dermatitis by changing a skin cell's configuration so that it is no longer recognized by the immune system as part of the body. (wikipedia.org)

  • A large meta-analysis of pooled results from 19 trials with 33,826 participants, suggests that salmeterol may increase the small risks of asthma-related deaths, and this additional risk is not reduced with the additional use of inhaled steroids (e.g., as with the combination product fluticasone/salmeterol).
