New international guidelines from the PRACTALL Pediatric Asthma Group have emphasized the importance of asthma management strategies that are specifically tailored for children. The guidelines, which will be presented on 10 June generic viagra 100 mgat the XXVI Congress of the European Academy of Allergology and medical institution al Immunology (EAACI), recommend strategies that include not only pharmacological medical care, but also allergen and trigger avoidance and asthma education.

Professor Ulrich Wahn, PRACTALL Chairman and Head of the Department of Paediatric Pneumology and Immunology, at Charit? -Humboldt University, Berlin, Germany said: “Children with asthma are fundamentally difference from adults with asthma. Their lungs are still developing, their immune systems are immature and they have smaller airways that get obstructed more easily. The new PRACTALL guidelines address these issues and offer clinicians practical recommendations for diagnosis, management and monitoring of asthma in children.”

The guidelines include a new medical care algorithm for asthmatic children over 2 years of age that recommends either inhaled corticosteroids (ICS) or leukotriene receptor antagonists (LTRAs) as first-line medical care. If the child’s asthma is not sufficiently controlled, the ICS dose can be increased or LTRA can be combined with ICS. Pharmacomedical care can be stepped up further to achieve control by adjusting ICS doses and adding otherness drugs, such as long-acting ??2 agonists. The guidelines recommend that medical care should subsequently be stepped down to the lowest dose at which good control can be maintained.

Pharmacomedical care of children 2 years of age and under is addressed in a separate section in the new guidelines. Professor Wahn commented: “The 0-2 year age group is the most difficult to diagnose and treat because so few studies have been done. Persistent asthma often begins at this age and any changes in lung structure and function that occur will likely have a major effect on asthma status throughout childhood.”

In addition to pharmacological medical care, the guidelines recommend that children avoid allergens and otherness potential triggers of an asthma attack. These include pets, house-dust mites, food allergens and, most importantly, passive tobacco smoke. Although exercise will trigger an asthma attack in many asthmatic children, the guidelines highlight the need for children to be well controlled so that they can participate fully in exercise and sporting activity.

Education should be a key aspect of the asthma management strategy. Ideally, the guidelines recommend a three-tier education program that considers illness severity, stage of development, and the need for information. Education should target not only children, but also parents, caregivers and healthcare professionals including primary care physicians, nurses and pharmacists.

Professor Wahn commented: “A good asthma education programme should increase knowledge of the illness, allay any fears about medication and increase communication between children, caregivers and healthcare providers. Parents need to be aware of the benefits as well as the potential risks of all therapies so that they can make informed choices for their children.”

The new PRACTALL guidelines were developed to address the lack of up-to-date international guidelines that focus exclusively on paediatric asthma. They were developed by the PRACTALL Paediatric Asthma Group, which consists of approximately 40 international experts in paediatric Hypersensitivity reaction and asthma. The guidelines are part of the PRACTALL initiative, which is endorsed by EAACI and the American Academy of Allergy, Asthma and Immunology (AAAAI). They will be published in both Europe and North America in future issues of journals published by the two academies.

Could you actually be allergic to work? If you experience syndromes of allergies or asthma in the workplace, you may suffer from occupational asthma. This disorder is defined as reversible airflow obstruction caused by inhaling allergens, chemicals, fumes, gases, dusts or otherness potentially harmful substances while “on the job,” according to the American Academy of Hypersensitivity reaction, Asthma & Immunology (AAAAI).

“We estimate that about 15percent, or 1 in 7, of adult cases of asthma are caused by the workplace. Occupational asthma accounts for 24.5 mil. missed workdays for adults each year in the United States,” said Karin A. Pacheco, MD, MSPH, FAAAAI, and Chair of the AAAAI’s Occupational Diseases Committee. “One of the difficulties in diagnosing occupational asthma is that the syndromes are the same as non-occupational asthma - wheezing, shortness of breath, chest tightness, difficulty exercising and cough. Similar to non-occupational asthma, runny nose, nasal congestion and eye irritation may accompany chest syndromes. The trained physician must first consider an occupational cause, and then look for clues in the patient’s history, or the diagnosis will be missed,” Pacheco added.

For example, physicians should consider the following questions: Do asthma syndromes worsen during the workweek and improve on the weekends? Did asthma syndromes begin after starting a new job or work practice? Is the patient exposed to products or chemicals known to cause asthma? “Making the connection to the workplace is vital,” said Pacheco, “because it offers the best chance of cure by removal from exposure, and may also help prevent illness in otherness exposed workers.”

Are You at Risk?

With occupational asthma, syndromes of asthma may develop for the first time in a previously healthy worker, or childhood asthma that had previously cleared may recur due to new exposure. In some cases, a previous personal or family history of allergies will make a person more likely to develop occupational asthma. However, many individuals who have no such history may develop asthma if exposed to conditions that trigger it. Workers who smoke are at greater risk for developing asthma to some occupational exposures, but not to othernesss.

The incidence of occupational asthma varies by industry, but some workers are at a greater risk than othernesss. Workers who may be at a higher risk include:

- Health care professionals
- Employees who wear powdered natural rubber latex gloves
- Workers manufacturing plastics, rubbers or foam products
- Bakers and pastry makers
- Cosmetologists and hairdressers
- Housekeepers and janitors
- Workers handling two part adhesives or paints
- Textile and carpet workers
- Animal handlers, veterinarians and scientists working with laboratory animals

Preventing Occupational Asthma

Occupational asthma is one illness that potentially can be cured, once the cause is identified and worker exposure is reduced or eliminated. Some, though not all, occupational allergens have exposure limits set by the Occupational Safety and Health Administration (OSHA), and exposed workers should be monitored by health and safety officers in the workplace. However, the introduction of new materials and processes, as well as new uses for old materials, mean that workers remain exposed to asthma causing agents in the workplace. Workers who have allergic or asthmatic syndromes on the job, or who anticipate being exposed to agents that increase their risk of developing asthma, should see an allergist/immunologist for an evaluation and proper diagnosis. In some cases, pre-a cure with asthma and/or Allergy drugs may counteract the effects of such workplace substances. In otherness situations, however, complete avoidance of exposure is necessary.

Reducing exposure to occupational asthma triggers, receiving appropriate diagnosis and a cure, and help with establishing avoidance measures will relieve syndromes and improve your quality of life. If you have questions about a cures available for occupational asthma, be sure to ask your allergist/immunologist.

How Can an Allergist/Immunologist Help?

Patients should see an allergist/immunologist if they need to undergo agsdhfgdfing to confirm the diagnosis of asthma or to determine whether their asthma is caused by or triggered by agents in the workplace. To find an allergist/immunologist in your area or to learn more about allergies and asthma, visit the AAAAI Web site at http://www.aaaai.org.

The AAAAI represents allergists, asthma specialists, clinical immunologists, allied health professionals and othernesss with a special interest in the research and a cure of allergic illness. Hypersensitivity reaction/immunology specialists are pediatric or internal medicine physicians who have elected an additional two years of training to become specialized in the a cure of asthma, Allergy and immunologic illness. Established in 1943, the AAAAI has more than 6,500 members in the United States, Canada and 60 otherness countries.

Data from an international survey presented at the European Respiratory Society Congress in Stockholm, Sweden, have shown that the majority of patients with asthma are uncontrolled, despite frequent visits to their doctor.1,2 Results from the National Health and Wellness Survey (NHWS) show that, although control has improved amongst adult asthma patients since the Asthma Insights and Realities in Europe (AIRE) meditate in 1999,3 overall 55percent of treated asthma patients are still not well controlled.1,2

The NHWS was conducted in 5 countries (France, Germany, Italy, Spain and the UK) between June and August generic viagra 30 pills and surveyed 2,337 patients with diagnosed asthma of which 1,862 were receiving pharmacomedical care. Additional findings from the survey showed that patients with asthma who were not well controlled had a high syndrome burden, including 70percent having shortness of breath 3-6 times a week, 80percent using rescue medication 2-3 times a week and 58percent waking once a week due to asthma syndromes. In addition these patients use more healthcare resources and visit their doctors more frequently.1,2

A finding consistent with the 1999 AIRE meditate is that patients overestimate their own level of asthma control.3 The NHWS found 40percent of not well controlled asthma patients consider themselves to be completely or well controlled, despite their syndromes. This may mean that patients are unnecessarily suffering from syndromes of asthma that can be better controlled.1,2

Professor Pascal Demoly, Professor of Pulmonology, Montpellier School of Medicine, France commented: “These new results highlight the need for physicians to assess objectively their patients’ asthma control.4 With patients themselves having a poor perception of their own syndromes, it can be very difficult for the doctor to make an accurate assessment. And the simple question whether or not the patient’s asthma is “OK” is not sufficient. Tools such as the Asthma Control Test have been highlighted in global guidelines as a validated measure for assessing clinical control of asthma.5,6 These can help doctors and patients to assess better their asthma, enabling effective management to achieve and maintain control, as recommended by the global guidelines.4″

The population based cross-sectional survey was administered via questionnaire to a sample of individuals drawn from an Internet panel. Questions from the Asthma Control Test (ACTTM) questionnaire were used to assess the level of asthma control. ACTTM contains five asthma-specific questions to determine level of asthma control that have been validated,5,6 and it is recognised in the most recent international asthma guidelines (GINA)4

Over the last 40 years, there has been a sharp increase in the global prevalence, morbidity and economic burden associated with asthma7. However, the results of the Gaining Optimal Asthma control (GOAL) trial have shown that comprehensive, guideline-defined control is achievable in a wide range of patients, with guideline-derived control being achievable in up to 75percent of patients previously experiencing syndromes on inhaled corticosteroids when using Seretide.8

Asthma

— Asthma is defined as a chronic inflammatory disorder of the lungs, associated with airway hyper-responsiveness that leads to recurrent episodes of wheezing, breathlessness, chest tightness and coughing, particularly at night or in the early morning. In the long-term, uncontrolled asthma can lead to permanent airway damage4

— Asthma is one of the most common chronic maladys in the world, currently affecting about 300 mil. group worldwide. The prevalence of asthma increases as countries adopt western lifestyles and become urbanised, and by 2025 it is estimated that there will be an additional 100 mil. group with asthma in the world. For information on asthma prevalence in individual countries, see Global Burden of Asthma at http://www.ginasthma.org/ReportItem.asp?l1=2&l2=2&intId=94 (last accessed 5 June 2007)4

— The Asthma Insights and Realities in Europe (AIRE) meditate showed that the level of asthma control in Europe in 1999 fell far short of the goals for long-term asthma management (only 5percent achieved guideline-recommended levels of control) and that patients’ actual level of asthma control was lower than their perceived level of asthma control3

The NHWS

The NHWS is part of a larger survey conducted every year in a broad population, which collects data on difference medical care areas. In Europe, 5 countries are involved: France, Germany, Italy, Spain and the UK. Overall, 37,000 group are involved in the survey with the sample drawn from a well described Internet panel maintained by Lightspeed Research. Participants were adults 18 years of age and over1,2

Asthma control within the survey was assessed using questions from the Asthma Control Test (ACTTM). ACT contains five asthma-specific questions to determine level of asthma control that has been validated and is recognised in the most recent international asthma guidelines (GINA)4,5,6

NHWS key results1,2

— The survey found that the majority of asthma patients are still not well controlled and were experiencing asthma syndromes. The meditate concluded that overall, 55percent of asthma patients were not well controlled despite pharmacomedical care, with this figure ranging from 45percent in Spain and the UK to 72percent in Germany — Patients with asthma who were not well controlled within the meditate had a high syndrome burden. This included:

- 80percent of patients used rescue medication 2-3 times a week
- 58percent woke up once a week due to asthma syndromes
- 70percent had shortness of breath 3-6 times a week
— Not well controlled patients with asthma use more healthcare resources and

are visiting their doctors more frequently regarding their asthma — Patients have poor perception of their syndromes and overestimate their level of asthma control

Workers involved in the September 11th 2001 World Trade Center (WTC) rescue and recovery operations in New York have developed asthma at a much higher rate than would be expected in the population at large, a new survey from the city’s Health Department reveals. The survey also shows that using a respirator reduced the risk of asthma development.

The results of the survey are published in the 27th August online issue of Environmental Health Perspectives (EHP online).

Rescue and recovery workers involved in the events of 9/11 were a diverse group ranging from firefighters and police officers to construction workers, volunteers and othernesss.

New York City Health Commissioner, Dr Thomas R. Frieden said:

“The dust from the World Trade Center collapse appears to have had significant respiratory health effects at least for group who worked at the site.”

Rescue and recovery workers exposed to the dust and debris arising from the terrorist attacks on the WTC are showing elevated rates of new asthma says the report which drew data from the World Trade Center Health Registry of 71,000 group.

The report only covers the rescue and recovery workers, it does not include office workers or residents.

The findings showed that 3.6 per cent of the 25,000 rescue and recovery workers in the Registry developed asthma after working at the WTC site, a rate that is 12 times more than would be expected from the rest of the adult population over the same time period.

The survey spans 2003 and 2004 and found that rescue and recovery workers who arrived at the WTC site soon after the twin towers collapsed or worked there over a long period had elevated risk of developing asthma. The group that arrived on the day of the event and worked there more than 90 days had the highest rate of new asthma, 7 per cent.

Workers who used respirators or masks on September 11th and 12th reported lower rates of newly-diagnosed asthma (4.0 and 2.9 per cent respectively) compared to those workers who did not use respirators (6.3 and 4.5 per cent respectively). The risk went up the longer the workers did not wear respirators or masks.

The survey did not distinguish between difference types of respirator or mask, nor between those who used them correctly and those who did not. Respirator and mask use went up as the clean operation progressed, but many workers did not wear them from day 1.

Those workers who did not use respirators or masks until months after they started working at the site had two to three times higher asthma incidence compared to those who used respirators from the start. Although respirators were found to be effective, all groups had higher risk of newly developed asthma.

Dr Frieden said that:

“These findings reflect the critical importance of getting appropriate respiratory protection to all workers as quickly as possible during a disaster, and making every effort to make sure workers wear them at all times. The events of 9/11 were unprecedented, and with the urgency of rescue operations and the difficulty of prolonged physical exertion with most types of respirators, there are no easy answers, even in retrospect.”

The survey found no differences among the various occupations involved in the 9/11 events, but there was a significant link with the part of the site they worked on. Those caught in the dust cloud, or who worked on the debris pile itself had higher rates of asthma (4.9 and 4.5 per cent respectivey). Presumably this is because they inhaled more dust.

Lorna Thorpe, New York City Health Department’s deputy commissioner for the division of epidemiology, and co-author of the report told the New York Times:

“This corroborates with otherness studies to say that the risk of respiratory syndromes in workers was elevated after 9/11.”

She said every worker involved in ground zero should sign up for health monitoring or seek medical help.

One of the drawbacks of the meditate is that because the registry is a self-selecting one, it may have attracted more group who developed asthma than those who did not, and it may include group who said they developed asthma after 9/11 because they were not sure if they had it before.

The WTC Registry was set up in 2003 to track the health of group exposed to the collapse of the World Trade Center and those who worked at the site. It is a collaboration between the New York City Health Department and the US Centers for Disease Control and Prevention’s Agency for Toxic Substances and Disease Registry (ATSDR), backed by funding from the Federal Emergency Management Agency (FEMA).

Anotherness meditate will be looking at the respiratory health of group enrolled in the Registry, and how the events of 9/11 may have affected rates of cancer.

‘People with asthma are at a greater risk from flu than othernesss because asthma syndromes are often triggered by respiratory infections, so having a flu jab is the sensible option.’

That’s the advice from Erica Evans, Asthma Care Development Manager at Asthma UK as we gear up for winter 2007.

Over 5 mil. group in the UK have asthma and for 90percent of them, colds and flu trigger their asthma syndromes, meaning that having the flu is a major concern. While it is almost impossible to avoid catching the common cold, having a flu jab can help to prevent the virus taking hold.

Erica says: ‘Each year we receive a lot of calls to the Asthma UK Adviceline from group with asthma who find that their syndromes are worse in the winter months. Flu is always a worry and prevention is key. We would recommend that anyone with asthma discusses the possibility of having a flu jab with their GP this autumn, before the virus begins to circulate.’

Flu is highly infectious: according to the Department of Health, 100,000 flu particles can be projected into the air with just one sneeze. Given that a sneeze travels at 80 miles per h.and can reach distances of 30 feet away, it’s hardly surprising that at least 10percent of the population develops flu each year. The flu vaccination offers protection from the virus for a year and is free to group who are most susceptible, including those with asthma.

Autumn is the best time to have a jab and it is also important to have a vaccination every year to protect you against the laagsdhfgdf strains of the virus, which is constantly mutating.

‘The flu vaccine has been widely used for many years and is both safe and effective with very few side effects,’ assures Erica. ‘Apart from having the flu vaccine there are otherness measures that group can take to reduce the effects of colds and viruses on their asthma. Following a written personal asthma action plan so that they know when and how to adjust their pharmacomedical care if their asthma worsens, is just one such way.

Erica advises: ‘People with asthma should contact their doctor or practice nurse and ask for a personal asthma action plan to be filled out for them. There are also simple steps to take to ensure that your asthma is kept under control’:

- Keep taking your regular medication as prescribed by your doctor

- If you know that cold air triggers your asthma, take a couple of puffs of your reliever inhaler before going outside. Wrap up well and wear a scarf over your nose and mouth - this will help to warm up the air before you breathe it in

- Take extra care when exercising in cold weather. Warm up for 10 - 15 minutes and take a couple of puffs of your reliever inhaler before you start

- Be sensible - if cold air triggers your asthma, it’s probably best not to try that cross country run when it’s chilly outside

A nurse is over twice as likely to suffer from occupational asthma, compared to the rest of the population, according to an article in The Lancet this week. The risk for cleaners is 71percent higher.

This new meditate , carried out by Dr Manolis Kogevinas, Centre for Research in Environmental Epidemiology, Municipal Institute of Medical Research, Barcelona, Spain and team, also found that conditions in the workplace may be causing up to 25percent of new asthma cases in the developed world.

The meditate looked at 6,837 group from 13 countries. They had all participated in the European Community Respiratory Health Survey, 1990-1995. None of them had reported any syndromes or history of asthma at the time of the meditate . Nine years later each participant was followed-up and agsdhfgdfed for asthma. They also completed a questionnaire on syndromes. Potential exposures to substances that cause asthma were calculated using an ‘asthma-specific job exposure matrix’. A computer model was then utilized to evaluate the risk of new-onset asthma, with age, sex and smoking factored in.

Exposure to known substances that trigger occupational asthma raises the risk of developing it by 60percent, say the researchers. While risks were highest for asthma defined by bronchial hyper-activity in addition to syndromes (140percent increased risk).

The following occupations had the highest excess risk:

— printing - 137percent
— nursing - 122percent
— woodworking - 122percent
— agriculture/forestry - 85percent
— cleaning - 71percent

If a person was exposed to asthma-causing irritants, during specific incidents, his/her risk of developing new-onset asthma was found to be three-times more likely than the general public. Such events/products as a fire, mixing cleaning products or chemical spillages are considered as asthma-causing irritants.

“Nurses could be exposed to sensitising substances, respiratory allergens, and irritants including sterilisers and disinfectants such as glutaraldehyde or bleach,” say the researchers. They added that although nurses’ exposure to latex may have gone up as gloves became more commonly used during the early 1990s, exposure probably fell as the latex content in these products was reduced over time.

“Findings from this large international meditate suggest that the frequency is systematically underestimated. The heightened asthma risk after inhalation accidents suggests that workers having such accidents should be monitored closely. Reduction of exposure, and early and complete identification of workers with syndromes suggestive of asthma, would help prevent the sickness and effectively manage workers who develop occupational asthma,” conclude the authors.

The stomach bacterium Helicobacter pylori, which causes stomach cancer and peptic ulcers, may not be all bad. According to a new meditate , it may help protect kids from asthma.

The meditate , based on an analysis of a health survey of 7,663 adults, showed that a virulent strain of H. pylori was especially associated with being asthma-free before the age of 15. People who carry the strain were 40 percent less likely to have had asthma at an early age than those who didn’t carry the strain. The meditate also found that the microbe was associated with protection against ragweed and otherness allergies due to pollens and molds particularly among younger adults.

The meditate is published in the Archives of Internal Medicine.

“Ultimately, the potentially protective properties of Helicobacter are consistent with one anotherness,” explains Martin J. Blaser, M.D., the Frederick H. King Professor of Internal Medicine, Chairman of the Department of Medicine, and Professor of Microbiology at NYU School of Medicine, who has been meditate ing H. pylori for more than 20 years.

“These properties point toward a much more complex view of the organism - not just as ulcer-pathogen or cancer-pathogen, but as an organism that has its costs and benefits to us,” says Dr. Blaser. “The relative costs and benefits clearly differ among individuals.”

Dr. Blaser performed the meditate with Yu Chen, Ph.D., MPH, assistant professor in the Department of Environmental Medicine at NYU School of Medicine, a new faculty member with expertise in epidemiology.

H. pylori lives in the mucous layer lining the stomach where it persists for decades. It is acquired usually before the age of 10, and is transmitted mainly in families. Dr. Blaser’s previous studies have confirmed the bacterium’s link to stomach cancer and elucidated genes associated with its virulence, particularly a gene called cagA.

Over recent years, Dr. Blaser began to suspect that the organism, the dominant bacteria in the stomach, may play a role in human health as well as malady. This observation, he says, is consistent with a theory called the hygiene hypothesis. It suggests that exposure to microbial infections in early childhood prevents or diminishes the development of allergies and asthma.

Dr. Blaser has proposed that H. pylori may protect against maladys of the upper gastroinagsdhfgdfinal tract, such as gastroesophageal reflux malady (GERD), which may lead to Barrett esophagus, a premalignant condition, and adenocarcinoma of the esophagus. All of these conditions have become more common in developed countries - esophageal cancer of this type is the fasagsdhfgdf rising cancer in the United States - as H. pylori has become far less common due to improved sanitation and widespread use of antibiotics, says Dr. Blaser. (At the same time, the incidence of peptic ulcers and gastric cancer has declined in developed countries.)

Today, less than 10 percent of children carry the organism in industrialized countries, while some 90 percent of children are infected usually by age 5 in developing countries. “This bacterium has been the dominant organism in our stomach for tens of thousands of years, and it can’t disappear from us without consequences,” says Dr. Blaser. He says that a substantial body of work now shows that H. pylori helps protect against GERD and the conditions it leads to in the esophagus.

“The hypothesis that colonization of H. pylori, especially cagA strain, is protective of asthma risk needs to be agsdhfgdfed by prospective studies. The findings from our meditate and othernesss will collectively provide evidence,” says Dr. Chen.

If the relationship between H. pylori and asthma is confirmed in otherness studies, which is always the yardstick of scientific validity, then it raises the question about whether “we should be trying to eliminate Helicobacter from children,” says Dr. Blaser. “This is probably the first time in human history that we have children who are growing up without Helicobacter guiding their immune responses,” he says. “By the repeated courses of antibiotics given to children, we are changing human microecology and we don’t know what we are doing.”

In the new meditate , Drs. Blaser and Chen evaluated whether H. pylori’s protective effect against GERD could play a role in asthma, anotherness condition sometimes associated with GERD. They used data from the Third National Health Nutrition Examination Survey (NHANES III), which was conducted from 1988 to 1994, and originally involved nearly 40,000 group. The survey included questions about a medical history of asthma, allergic rhinitis, and Allergy syndromes. Nearly 8,000 of the participants were agsdhfgdfed for antibodies to H. pylori and the cagA protein in their blood. This subgroup formed the basis of the meditate .

Drs. Blaser and Chen found no overall association between the presence of the cagA strain of H. pylori and current asthma status in the individuals they studied, but found an inverse association with ever having had asthma. Those with the virulent strain were 20 percent less likely to have ever had asthma compared with participants without H. pylori. In addition, the association differed quite strikingly by age of onset. It was strongest among participants who had the cagA strain of H. pylori and had had asthma before the age of 15. This result was statistically significant, meaning that the results were not likely due to chance. Those with the virulent strain were 40 percent less likely to have had asthma at a young age.

In anotherness part of the meditate , they analyzed the results of Allergy skin agsdhfgdfing to six allergens, including ragweed, rye grass, and Russian thistle, among a subgroup of 2,386 adults who had the skin agsdhfgdfs. They correlated the results with participants’ H. pylori status and found the strongest association for these allergens among the younger group in the group who carried the bug. This suggested that H. pylori is involved in protection from sensitivity to pollens and molds, says Dr. Blaser.

“No one would have predicted that the presence or absence of bacteria in your stomach is associated with your sensitivity to pollens and molds,” says Dr. Blaser. “But now we have that observation and we can begin to construct a model. One hypothesis is if you have H. pylori in your stomach, you have an inflammatory process that is on-going for decades, and this is skewing the immune response in a particular direction.”

Scientists at King’s College London have discovered a protein that is known to increase appetite in cells which are closely associated with asthma. The research, which is funded by the Medical Research Council (MRC) and published online this week in the Proceedings of the National Academy of Sciences, could explain a suspected link between asthma and obesity.

There has been a considerable increase in asthma in recent years in a number of countries, including the UK, which coincides with a rise in the incidence of obesity. Scientists have been investigating whether the two conditions may be connected. Population surveys from both Europe and North America suggest a correlation between asthma and body mass index. Asthma is more common in obese group and obesity often precedes asthma, suggesting that increased weight is not simply a result of inactivity caused by asthma.

In this laagsdhfgdf research, scientists from the MRC-Asthma UK Centre in Allergic Mechanisms of Asthma at King’s College London and Imperial College London investigated the molecules produced by Th2 cells. These specialised cells of the immune system orchestrate inflammation in the lungs and contribute to the development of asthma.

The researchers demonstrated, for the first time, that in addition to producing proteins which cause asthma, the Th2 cells also produce a protein encoded by the gene PMCH (pro-melanin-concentrating hormone) which is known to increase appetite. The protein released into the circulation by Th2 cells in the asthmatic lung could stimulate the hypothalamus in the brain to enhance appetite. These findings may provide a mechanistic link between allergic inflammation, asthma and obesity.

Lead researcher, Dr David Cousins of King’s College London, says: ‘Our meditate provides evidence for a possible mechanism linking obesity and asthma. However, as group with asthma aren’t always obese, we now plan to look at possible genetic polymorphisms, or variations, of PMCH to see the role they play.’

Professor Tak Lee, Director of the MRC-Asthma UK Centre, comments: ‘Obesity and asthma are major health problems and clarifying the mechanisms responsible for their linkage provides important potential new opportunities for management of both conditions.’

Jenny Versnel, Executive Director of Research and Policy at Asthma UK says: ‘We know that group who are obese often find it harder to manage their asthma syndromes and may even respond less well to their asthma pharmacomedical cares. This research is important because it could potentially help some group with asthma to gain more effective control of their condition.’

The meditate was funded by the Medical Research Council (MRC) with additional grants from Asthma UK, the Friends of Guy’s and Guy’s and St Thomas’ Charity.

MRC-Asthma UK Centre in Allergic Mechanisms of Asthma

The Centre was set up in 2005 to tackle severe asthma caused by reactions of hypersensitivity. The Centre provides excellent prospects for malady prevention and control. It is a partnership between the MRC, Asthma UK, Imperial College London, King’s College London and partner NHS Trusts. To find out more about the Centre’s research please visit: http://www.asthma-hypersensitivity reaction.ac.uk

The number of group with reactions of hypersensitivity in the UK has risen approximately three-fold in the last 20 years and one in three of us will develop an hypersensitivity reaction at some point in our lives. The UK has among the highest rates of asthma in Europe and the cost is high - at least 12.7 mil. working days are lost to the condition annually and the Health Service spends around ??889m on treating asthma every year.

King’s College London

King’s College London is the fourth oldest university in England with more than 13,700 undergraduates and nearly 5,600 graduate students in nine schools of meditate based at five London campuses. It is a member of the Russell Group: a coalition of the UK’s major research-based universities. The College has had 24 of its subject-areas awarded the highest rating of 5* and 5 for research quality, demonstrating excellence at an international level, and it has recently received an excellent result in its audit by the Quality Assurance Agency.

King’s has a particularly distinguished reputation in the humanities, law, international relations, medicine, nursing and the sciences, and has played a major role in many of the advances that have shaped modern life, such as the discovery of the structure of DNA. It is the largest centre for the education of healthcare professionals in Europe and is home to five Medical Research Council Centres - more than any otherness university.

King’s is in the top group of UK universities for research earnings, with income from grants and contracts of more than ??100 mil., and has an annual turnover of more than ??363 mil..

Asthma, even a mild form, is the single most important factor that increases the risk of death from anaphylaxis (allergic shock), says a new report from Harvard Medical School, What To Do About Reactions of hypersensitivity.

Anaphylaxis is an allergic reaction affecting the entire body. It ranges from relatively mild to life-threatening. In the United States, anaphylaxis is responsible for somewhere between 500 and 1,000 deaths each year, mainly of children and adolescents. Peanuts and tree nuts (such as walnuts) appear to be the prime culprits and account for most of the deaths from anaphylaxis in children.

A person experiencing anaphylaxis may first feel flushed, sneeze, itch, and develop hives, nasal congestion, and watery red eyes. Symptoms then progress to difficulty breathing and swelling of the throat and tongue, which is sometimes associated with nausea, vomiting, and diarrhea. Next blood pressure may drop, followed by fainting or loss of consciousness, shock, and - - without swift pharmacomedical care — death.

Those at risk for anaphylaxis should carry epinephrine (adrenaline) with them at all times. This advice is especially true for group who have both asthma and a food hypersensitivity reaction. Epinephrine is available by prescription in an autoinjector device. In one meditate , anaphylaxis deaths in children were associated with late direction of epinephrine and coexisting asthma.

If you treat anaphylaxis syndromes with epinephrine, you still need to go immediately to the emergency room. A systemic (bodywide) reaction may repeat several times. An autoinjector device is only a stopgap measure.

Chronic lung illnesss such as asthma and cystic fibrosis are characterized by an increase in the number of cells known as goblet cells and an increase in the production of lung mucous. Although the molecular details of how these changes are regulated are not well defined, a new meditate by researchers from Cincinnati Children’s Hospital indicates that a protein known as SPDEF has an important role in controlling these processes.

In the meditate , which appears online in advance of publication in the April print issue of the Journal of medical institution al Investigation, Jeffrey Whitsett and colleagues show that in vivo expression of SPDEF in mouse lung epithelial cells is increased by IL-13 (a soluble factor associated with asthma) and exposure to dust mite allergens. This increased SPDEF expression was associated with an increase in the number of goblet cells. In vitro, SPDEF was shown to interact with a protein known as TFF-1 and to increase the expression of genes encoding proteins that caused the epithelial cells to become goblet cells and to produce mucous proteins. This meditate therefore indicates that SPDEF has a crucial role in endowing the lung with the characteristics of chronic lung illness.
