How to Live Well with Asthma in the Post-COVID Era

The COVID-19 pandemic has been a tough time for everyone, especially for people with asthma. Asthma is a chronic condition that affects the airways and makes it hard to breathe. People with asthma may have more severe symptoms or complications if they get infected with COVID-19. That’s why it’s important to know how to manage your asthma and protect yourself from the virus.

But even as the pandemic seems to be winding down, the challenges are not over for people with asthma. Many people still live in fear of getting sick or infecting others. Many people still face stress, anxiety, depression, or isolation due to the pandemic. Many people still struggle with access to health care or vaccines.

That’s why we need to learn how to live well with asthma in the post-COVID era. In this blog post, we will share some insights from recent studies and some tips on how to cope with the physical and mental health challenges of asthma and COVID-19.

Summary

The COVID-19 pandemic has had a significant impact on the quality of life and treatment of asthma patients around the world. A recent study by Naglaa Youssef and colleagues surveyed 200 asthma patients in Egypt and found that 80% of them had uncontrolled asthma, meaning that their symptoms were frequent or severe and interfered with their daily activities. The most common factor that affected their quality of life was the limitation of activity, such as exercise, work, or socializing. Women reported a higher level of perceived threat from COVID-19 than men.

The study also found some positive changes in the patients’ health behaviors during the pandemic. More patients visited their clinician regularly and followed their treatment plan than before the pandemic. However, over 75% of the patients could not tell the difference between asthma and COVID-19 symptoms, which could lead to confusion or delay in seeking medical help.

The study concluded that the COVID-19 pandemic improved some aspects of asthma care, but also highlighted the need for better asthma control and education. Uncontrolled asthma is a major risk factor for poor quality of life and should be addressed by both patients and clinicians.

Another study by Valeria Saladino and colleagues explored the psychological and social effects of the pandemic on the population, mostly children, college students, and health professionals. They found that these groups were more likely to develop post-traumatic stress disorder, anxiety, depression, and other symptoms of distress due to the pandemic. They also found that social distancing and security measures affected the relationship among people and their perception of empathy toward others.

The study suggested that telepsychology and technological devices could be useful tools to decrease the negative effects of the pandemic and improve psychological treatment of patients online. Telepsychology is the delivery of psychological services using telecommunication technologies, such as phone calls, video calls, or online platforms. Telepsychology can offer benefits such as convenience, accessibility, affordability, and continuity of care.

Key takeaways

Here are some key takeaways on how to live well with asthma in the post-COVID era:

• Keep your asthma under control. Follow your asthma action plan, take your medications as prescribed, monitor your symptoms and peak flow, and avoid triggers that can worsen your asthma.

• Protect yourself from COVID-19. Follow the public health guidelines to prevent the spread of the virus. Wear a mask when you are in public places, wash your hands frequently, practice social distancing, and get vaccinated when it’s available for you.

• Seek medical help when needed. Don’t hesitate to contact your clinician if you have any questions or concerns about your asthma or COVID-19. If you have symptoms of COVID-19, such as fever, cough, shortness of breath, or loss of taste or smell, get tested and isolate yourself until you get the results.

• Stay active and healthy. Physical activity can improve your lung function and overall health. Choose activities that are suitable for your fitness level and don’t trigger your asthma. Eat a balanced diet, drink plenty of water, and get enough sleep.

• Seek support and information. Living with asthma can be stressful and isolating, especially during a pandemic. Reach out to your family, friends, or support groups for emotional support. You can also visit the World Asthma Foundation website to learn more about asthma and how to manage it during the pandemic.

• Practice empathy. Empathy is the ability to understand and share the feelings of another person. It can help you to care for others, cooperate with them, and support them in times of need. Empathy can also motivate you to follow public health guidelines and get vaccinated to prevent the spread of the virus.

• Use telepsychology. Telepsychology is a convenient and effective way to access psychological services online. It can help you cope with stress, anxiety, depression, or other mental health problems caused by the pandemic. It can also help you improve your relationship with yourself and others.

Conclusion

Asthma is a common chronic condition that can impair your quality of life if it’s not well controlled. The COVID-19 pandemic has added more challenges and risks for people with asthma. However, by following some simple steps, you can live well with asthma in the post-COVID era.

The World Asthma Foundation is a non-profit organization that aims to empower the world asthma community through education, collaboration, and advocacy. Our vision is to see a day where they can improve the quality of lifem for all asthmatics.
We do this by advocating for an improved understanding
of the causes, diagnostic tools, methodologies, precision therapies, prevention, sustainability in healthcare, and one day
a cure.

Infectious Asthma: Understanding the Complex Interplay between Infections and Asthma

Greetings to Members and Subscribers of the World Asthma Foundation

As a chronic respiratory disease, asthma affects millions of individuals worldwide, causing inflammation and narrowing of the airways, leading to breathing difficulties, coughing, and wheezing. Asthma can have a significant impact on individuals and their families, as well as the broader society, due to the high cost of treatment and the potential for reduced quality of life. Recent research has explored the relationship between infections and asthma, with a focus on the role of infections in exacerbating asthma symptoms. The World Asthma Foundation aims to provide a comprehensive review of the latest research related to infections and asthma, and to explore potential strategies for managing and preventing infection-related asthma.

Introduction

While the exact causes of asthma are not fully understood, researchers have identified several factors that can contribute to the development and exacerbation of the disease, including infections. Infections can be caused by a range of pathogens, including respiratory viruses, bacterial infections, and fungi, among others. Although the relationship between infections and asthma has been widely studied, a fundamental question that remains to be addressed is whether infections may be responsible for creating the asthmatic predisposition in the first place. Understanding the relationship between infections and asthma is critical for the management and prevention of asthma.

Infectious Agents and Asthma

Recent studies have shown that various infectious agents may contribute to the development and exacerbation of asthma. Respiratory viral infections, particularly those caused by rhinovirus and respiratory syncytial virus, have been linked to the development of childhood asthma. In addition, certain bacterial infections, such as those caused by Streptococcus pneumoniae and Haemophilus influenzae, may also contribute to the development of asthma.

More recent research has also implicated Chlamydia pneumoniae, Staphylococcus aureus, and Candida albicans as potential infectious agents linked to the development and exacerbation of asthma.

Chlamydia pneumoniae has been associated with a specific type of asthma, known as Chlamydia pneumoniae-mediated asthma. Staphylococcus aureus has been linked to the development of severe asthma, particularly in patients with atopic dermatitis. Candida albicans has been linked to the development and exacerbation of asthma, particularly in patients with severe asthma or fungal sensitization.

Antibiotics and Asthma

In addition to preventive strategies, such as avoidance and good hygiene practices, antibiotics may also have a role in the management of severe asthma. Azithromycin, an antibiotic, has been shown to be effective in reducing asthma exacerbations. However, the exact mechanism of action is not established, so it is unknown whether azithromycin works vis its antibiotic effects or because of some non-infectious anti-inflamatory activity. While most asthma specialists believe that azithromycin works because it is an anti-inflammatory, recent research suggests that it may be due to its antimicrobial effects against chronic atypical respiratory infections such as Chlamydia pneumoniae and Mycoplasma pneumoniae. It is important to note that a growing amount of research reflects that antibiotic use can contribute to dysbiosis and the development of asthma, and appropriate antibiotic use is necessary to prevent this potential negative impact on the microbiome.

Antifungal Therapy and Asthma

Fungi, particularly Candida albicans and Aspergillus fumigatus, have been implicated in the development and exacerbation of asthma. Fungal sensitization has been associated with more severe asthma and poorer asthma control. Some studies have shown that antifungal therapy may be effective in reducing asthma symptoms and improving lung function in individuals with fungal sensitization. However, the evidence for antifungal therapy in asthma is limited and further research is needed to fully understand the potential benefits and risks of this treatment. Moreover, antifungal therapy raises issues about efficacy and resistance, as improper use of antifungal medications can contribute to the development of drug-resistant fungi. Therefore, accurate diagnosis and appropriate use of antifungal therapy are necessary to prevent the development of drug-resistant fungi and ensure the safe and effective management of asthma.

Microbiome and Asthma

Recent research has also explored the role of dysbiosis, or an imbalance in the microbiome, in the development and exacerbation of asthma. The microbiome may influence asthma through several potential mechanisms, including modulation of the immune system and production of metabolites. While microbiome-targeted therapies, such as probiotics and fecal microbiota transplantation, may have potential as treatments for asthma, it is important to note that overuse of antibiotics can contribute to dysbiosis and the development of asthma. Therefore, appropriate antibiotic use is essential to prevent antibiotic overuse and the potential negative impact on the microbiome. Furthermore, the exact mechanisms by which dysbiosis influences asthma are not fully understood and require further research.

Challenges and Barriers

While significant progress has been made in understanding the relationship between infections and asthma, challenges and barriers remain. The lack of well-established classification and terminology for different types of infectious asthma is one such challenge. Further research is needed to develop a more comprehensive understanding of the complex interplay between infections and asthma, including the identification of specific types of infections that are most likely to trigger asthma exacerbations and the potential role of infections in creating the asthmatic predisposition.

Key Takeaway

  • Infections, particularly respiratory infections, have been linked to the development and exacerbation of asthma. Future research is needed to fully understand the complex interplay between infections and asthma.
  • Dysbiosis, or an imbalance in the microbiome, may contribute to the development and exacerbation of asthma.
  • Overuse of antibiotics can contribute to dysbiosis and the development of asthma. Therefore, appropriate antibiotic use is essential to prevent antibiotic overuse and the potential negative impact on the microbiome.
  • Fungi, particularly Candida albicans and Aspergillus fumigatus, have also been implicated in the development and exacerbation of asthma.
  • Antifungal therapy may be effective in reducing asthma symptoms and improving lung function in individuals with fungal sensitization, but further research is needed to fully understand the potential benefits and risks of this treatment.
  • Improper use of antifungal medications can contribute to the development of drug-resistant fungi, so accurate diagnosis and appropriate use of antifungal therapy are necessary to prevent the development of drug-resistant fungi and ensure the safe and effective management of asthma.
  • The exact mechanisms by which infections, dysbiosis, and fungi influence asthma are not fully understood and require further research.
  • It is essential to accurately diagnose and manage asthma to reduce the risk of exacerbations and improve quality of life.
  • This includes identifying and managing potential triggers, such as infections and dysbiosis.
  • Collaboration between researchers, healthcare providers, and patients is necessary to advance our understanding of the complex interplay between infections, dysbiosis, fungi, and asthma and develop effective strategies for managing this challenging disease.

Call to Action: Improving Diagnostic Tools and Methodology for Asthma

While significant progress has been made in understanding the relationship between infections and asthma, there are still challenges and barriers to identifying and managing the infectious agents that contribute to asthma development and exacerbation. One of the biggest challenges is the lack of well-established diagnostic tools and methodology for identifying the specific types of infections that are most likely to trigger asthma exacerbations.

Therefore, the World Asthma Foundation must call for increased research into developing and validating new diagnostic tools and methodology for infectious asthma. This research should focus on identifying new biomarkers that can be used to distinguish between different types of infectious asthma, and on developing new diagnostic tests that are highly sensitive and specific for detecting these biomarkers.

In addition, the World Asthma Foundation should advocate for increased funding for research into infectious asthma, including research into the mechanisms by which infectious agents contribute to asthma development and exacerbation, and the potential role of dysbiosis and the microbiome in infectious asthma.

Improved diagnostic tools and methodology for infectious asthma will be critical for developing more effective strategies for managing and preventing this challenging disease. By supporting research in this area, the World Asthma Foundation can make a significant impact on improving the lives of individuals living with asthma.

Future reports will delve further into the challenges and opportunities related to developing improved diagnostic tools and methodology for infectious asthma, highlighting new research and potential strategies for addressing this critical need.

Let’s work together to improve our understanding of infectious asthma and develop better ways to manage and prevent it.

Conclusion

Asthma is a complex respiratory disease with various factors that can contribute to its development and exacerbation, including infections.

A comprehensive understanding of the complex interplay between infections and asthma is critical for the management and prevention of asthma.

Further research is needed to develop more effective strategies for managing and preventing infection-related asthma.

As the World Asthma Foundation, it is essential to continue supporting and encouraging research into the relationship between infections and asthma, to improve the lives of those living with asthma.

Understanding and Managing Severe Asthma: Types, Symptoms, and Treatment

Severe asthma is a type of asthma that is difficult to control and can have a significant impact on a person’s daily life. Symptoms of severe asthma can include frequent exacerbations (attacks), high levels of asthma symptoms, and a need for high doses of medication to manage symptoms. Causes of severe asthma can include allergies, exposure to environmental triggers, and genetics. Treatment for severe asthma typically includes a combination of long-term control medications, such as inhaled corticosteroids and bronchodilators, as well as quick-relief medications to be taken during exacerbations. In some cases, additional treatments such as biologic medications or immunomodulators may be needed to manage symptoms.

Types of severe Asthma

There are several subtypes of severe asthma that can be characterized based on specific symptoms and causes. These include:

It’s important to note that some people may have characteristics of more than one subtype of severe asthma. It’s important to work with a healthcare professional to identify your specific subtype of asthma and develop a treatment plan that works for you.

Allergic Asthma

Allergic asthma is a subtype of severe asthma that is caused by an allergic reaction to a specific trigger, such as dust mites, mold, animal dander, pollen, or certain foods. The allergens cause the immune system to overreact and release chemicals, such as histamine, which can lead to inflammation and narrowing of the airways.

  1. Allergic asthma: characterized by an allergic reaction to a specific trigger, such as dust mites, mold, or pet dander.
  2. Non-allergic asthma: characterized by symptoms that are not caused by an allergic reaction, but rather by triggers such as viral infections, cold air, or exercise.
  3. Aspirin-exacerbated respiratory disease (AERD): characterized by severe asthma symptoms that are triggered by the use of aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs)
  4. Obesity-related asthma: characterized by asthma symptoms that are made worse by being overweight or obese.
  5. Occupational asthma: characterized by symptoms caused by exposure to specific triggers in the workplace, such as chemicals or dusts.
  6. Bronchial thermoplasty: characterized by symptoms caused by structural changes in the airways, such as thickening of the muscle layers that can make it harder to breathe.
  7. Eosinophilic asthma: characterized by a high number of white blood cells called eosinophils in the airways.

Symptoms of allergic asthma can include:

  • Shortness of breath
  • Wheezing
  • Chest tightness
  • Coughing, especially at night or early in the morning
  • Difficulty breathing, especially during physical activity
  • Rapid breathing

Allergic asthma is diagnosed through a combination of medical history, physical examination, and laboratory tests such as skin prick test or blood test (specific IgE) to determine the specific allergens to which an individual is sensitive.

Treatment for allergic asthma typically includes:

  • Avoiding exposure to allergens as much as possible
  • Long-term control medications, such as inhaled corticosteroids and bronchodilators
  • Quick-relief medications to be taken during exacerbations, such as short-acting bronchodilators
  • Allergen-specific immunotherapy (allergy shots) to help reduce sensitivity to specific allergens over time.

It’s important to note that many people with allergic asthma also have other allergic conditions, such as hay fever, eczema, or hives. They may have benefit from a comprehensive allergy management plan, including allergy testing and immunotherapy.

Non allergic asthma

Non-allergic asthma is a subtype of severe asthma that is not caused by an allergic reaction, but rather by other triggers such as viral infections, cold air, exercise, stress, or exposure to certain chemicals or pollutants. The exact cause of non-allergic asthma is not known, but it is thought to be related to changes in the airways that make them more sensitive to certain triggers.

Symptoms of non-allergic asthma can include:

  • Shortness of breath
  • Wheezing
  • Chest tightness
  • Coughing, especially at night or early in the morning
  • Difficulty breathing, especially during physical activity
  • Rapid breathing

Non-allergic asthma is diagnosed through a combination of medical history, physical examination, and laboratory tests such as pulmonary function test, to rule out other causes of asthma like infections or structural changes.

Treatment for non-allergic asthma typically includes:

  • Identifying and avoiding triggers as much as possible
  • Long-term control medications, such as inhaled corticosteroids and bronchodilators
  • Quick-relief medications to be taken during exacerbations, such as short-acting bronchodilators
  • Monitoring of symptoms and lung function regularly

It’s important to note that non-allergic asthma and allergic asthma can have similar symptoms and the distinction between the two subtypes can be difficult. A healthcare professional will work with you to identify the specific triggers of your asthma and create an individualized treatment plan.

Mucus Plugs and Asthma

Mucus plugs, also known as bronchial plugs, can be a complication of asthma. Mucus plugs are clumps of thick, sticky mucus that can block the airways and make it harder to breathe. They can form in the airways of people with asthma as a result of inflammation and increased mucus production in the lungs.

Symptoms of mucus plugs in asthma can include:

  • Shortness of breath
  • Wheezing
  • Chest tightness
  • Coughing, especially at night or early in the morning
  • Difficulty breathing, especially during physical activity
  • Rapid breathing
  • Wet or gurgling sounds when breathing
  • Increased mucus production and difficulty clearing mucus from the lungs

Mucus plugs can be caused by a number of factors, including exposure to triggers such as allergens, viral infections, or pollutants, as well as by changes in the airways that make them more sensitive to certain triggers.

Treatment for mucus plugs in asthma typically includes:

If you have asthma and are experiencing symptoms of mucus plugs, it’s important to speak with your healthcare professional to develop an individualized treatment plan. In some cases, additional treatments such as biologic medications or immunomodulators may be needed to manage symptoms.

Wheezing and Severe Asthma

Wheezing is a common symptom of severe asthma, as well as other types of asthma. It is a whistling or whistling sound that can be heard when breathing, especially during exhalation. Wheezing is caused by narrowed or obstructed airways, which can make it harder to breathe.

In severe asthma, wheezing can be a sign of increased inflammation and narrowing of the airways, which can lead to difficulty breathing and increased risk of exacerbations. The increased airflow resistance leads to increased air movement velocity, generating the wheezing sound.

Symptoms of severe asthma can include:

  • Frequent exacerbations (attacks)
  • High levels of asthma symptoms, such as shortness of breath, chest tightness, and coughing
  • A need for high doses of medication to manage symptoms
  • Increased risk of hospitalization
  • Difficulty with daily activities and impairment of quality of life

Treatment for severe asthma typically includes a combination of long-term control medications, such as inhaled corticosteroids and bronchodilators, as well as quick-relief medications to be taken during exacerbations. In some cases, additional treatments such as biologic medications or immunomodulators may be needed to manage symptoms.

It’s important to work closely with a healthcare professional to develop an individualized treatment plan for severe asthma. This may include regular monitoring of symptoms and lung function, as well as a plan to manage exacerbations and prevent future attacks.

  • Identifying and avoiding triggers as much as possible
  • Long-term control medications, such as inhaled corticosteroids and bronchodilators
  • Quick-relief medications to be taken during exacerbations, such as short-acting bronchodilators
  • Chest physical therapy, such as chest clapping and vibration, to help remove mucus from the lungs
  • Monitoring of symptoms and lung function regularly

Food Dye and Inflamation

Common food dye can trigger inflammatory processes, say university researchers

A recent university study funded by the Canadian Institutes of Health Research reflects that long-term consumption of Allura Red food dye can be a potential trigger of inflammatory bowel diseases (IBDs) and potentially other inflammatory diseases processes as well.

Researchers using experimental animal models of IBD found that continual exposure to Allura Red AC harms gut health and promotes inflammation. Researchers using experimental animal models of IBD found that continual exposure to Allura Red AC harms gut health and promotes inflammation.

‘This further understanding will benefit Asthmatics as well,’ said Alan Gray, Director at the World Asthma Foundation . The human gastrointestinal (GI) tract is home to a diverse ecosystem of microbes, known collectively as the microbiota. Among its many roles, the gut microbiota regulates the immune system and protects against harmful pathogens. In fact, the largest part of the immune system, the gut-associated lymphoid tissue, is found in the gut. This network of immune cells and tissues interacts closely with the gut microbiota, influencing inflammation throughout the body including the lungs.

The dye directly disrupts gut barrier function and increases the production of serotonin, a hormone/neurotransmitter found in the gut, which subsequently alters gut microbiota composition leading to increased susceptibility to colitis.

Khan said Allura Red (also called FD&C Red 40 and Food Red 17), is a common ingredient in candies, soft drinks, dairy products and some cereals. The dye is used to add colour and texture to foodstuffs, often to attract children.

The use of synthetic food dyes such as Allura Red has increased significantly over the last several decades, but there has been little earlier study of these dyes’ effects on gut health. Khan and his team published their findings in Nature Communications. Yun Han (Eric) Kwon, who recently completed PhD in Khan’s laboratory, is first author.

“This study demonstrates significant harmful effects of Allura Red on gut health and identifies gut serotonin as a critical factor mediating these effects. These findings have important implication in the prevention and management of gut inflammation,” said Khan, the study’s senior author, a professor of the Department of Pathology and Molecular Medicine and a principal investigator of Farncombe Family Digestive Health Research Institute.

“What we have found is striking and alarming, as this common synthetic food dye is a possible dietary trigger for IBDs. This research is a significant advance in alerting the public on the potential harms of food dyes that we consume daily,” he said.

“The literature suggests that the consumption of Allura Red also affects certain allergies, immune disorders and behavioural problems in children, such as attention deficit hyperactivity disorder.”

Khan said that IBDs are serious chronic inflammatory conditions of the human bowel that affect millions of people worldwide. While their exact causes are still not fully understood, studies have shown that dysregulated immune responses, genetic factors, gut microbiota imbalances, and environmental factors can trigger these conditions.

In recent years there has been significant progress in identifying susceptibility genes and understanding the role of the immune system and host microbiota in the pathogenesis of IBDs. However, similar advances in defining environmental risk factors have lagged, he said.

Khan said that environmental triggers for IBDs include the typical Western diet, which includes processed fats, red and processed meats, sugar and a lack of fibre. He added that the Western diet and processed food also includes large amounts of various additives and dyes.

He added that the study suggests a link between a commonly used food dye and IBDs and warrants further exploration between food dyes and IBDs at experimental, epidemiological and clinical levels.

World Asthma Day Summary

On the day after World Asthma Day, May 3, 2022, we scanned the globe to find a statement that best sums up the current state of affairs regarding Asthma.

Kudos to tbe U.S National Institute of Environmental Health NIH Statement on World Asthma Day 2022: Toward Improved Asthma Care

Good enough of summary that we want to publish this in its entirety.

Asthma is a serious lung disease; causes chest tightness, wheezing, and coughing; can often be controlled with proper treatment.

Today (May 3, 2022) on World Asthma Day, the National Institutes of Health reaffirms its commitment to biomedical research aimed at preventing the onset of asthma, understanding its underlying causes, and improving the treatment of it. This chronic airway disease, which is characterized by periodic worsening of inflammation that can make it hard to breathe, affects more than 25 million people in the United States, including more than 5 million children. Left untreated, it can be life-threatening.

While scientists have made substantial progress in understanding asthma diagnosis, management, and treatment, therapies to permanently improve breathing for those who suffer from asthma remain elusive. Researchers around the globe are working steadily toward this goal while they seek to better understand and find new ways to manage the disease. They also are continuing research on the underlying causes of disparities in the incidence, care, and prevention of the disease. On the heels of recently updated management and treatment guidelines, researchers anticipate a brighter future for people living with asthma.

Three NIH institutes primarily support and conduct studies on asthma — the National Heart, Lung, and Blood Institute (NHLBI); the National Institute of Allergy and Infectious Diseases (NIAID); and the National Institute of Environmental Health Sciences (NIEHS). Other NIH Institutes and Centers also support and conduct asthma research. NIH scientists and grantees made important advances in understanding, treating, and managing asthma in 2021, which are briefly highlighted as follows:

Asthma and COVID-19

An NHLBI-funded study showed that during the pandemic, asthma attacks, also known as asthma exacerbations, significantly decreased in a large group of children and adolescents, compared to the year before the pandemic. The study also found that telehealth visits among these patients increased dramatically during this time. The study included nearly 4,000 participants aged 5-17 years with a prior diagnosis of asthma. Researchers believe a better understanding of the factors that contributed to these improved outcomes could lead to better asthma control in all children and adolescents, as researchers noted no racial or ethnic differences in health outcomes in this population.

A NIAID-funded study found that asthma does not increase the risk of becoming infected with SARS-CoV-2, the virus that causes COVID-19. This finding came from a six-month household survey of more than 4,000 children and adults conducted between May 2020 and February 2021.

Asthma Disparities

Researchers have known for decades that social determinants of health – conditions like housing, neighborhood, education, income, and healthcare access – can affect the quality of life and asthma-related health outcomes of people living with the disease. NIH scientists are now reporting new advances in understanding the relationship between social determinants of health and asthma.

Black and Hispanic children who live in low-income urban environments in the United States are at particularly high risk for asthma attacks. These children tend to be underrepresented in large trials of new biologic therapies for asthma.

In a recent NIAID-supported clinical trial, the monoclonal antibody mepolizumab decreased asthma attacks by 27% in Black and Hispanic children and adolescents who have a form of severe asthma, are prone to asthma attacks, and live in low-income urban neighborhoods.

In one study, NHLBI-funded investigators demonstrated the importance of housing interventions in improving the health of children with asthma. Poor quality housing is associated with a high level of asthma triggers – including mold, cockroach, mouse, and dust mite allergens – that can pose a health threat to children with asthma. The study showed the feasibility of using targeted interventions – including better pest management, improved ventilation, and moisture reduction – to achieve healthy housing. It showed that such interventions can result in reduced symptoms and hospitalizations due to asthma.

Environmental Exposures and Asthma

Researchers have known for years that asthma can be triggered by substances in the indoor and outdoor environment. New research shows that exposure to some asthma triggers might even occur before birth.

In an NIH-supported study that included grant support from NIEHS and the NHLBI, researchers reported that prenatal exposure to tiny air pollution particles significantly increased the risk for developing asthma in children. The study, which analyzed data from two different study cohorts, focused on a group of mothers and their children, mostly Black or Hispanic, in the Boston area who lived near major roadways with heavy traffic. It found that more than 18% of the children who were exposed to high levels of these so-called ultrafine particles in the womb developed asthma in their preschool years, compared to 7% of children overall in the United States.

An NIEHS clinical study will assess how environmental factors affect disease progression in non-smoking adults who have moderate or severe asthma. The study will focus on the microbiological and genetic factors associated with atopic asthma, also known as allergic asthma, which is triggered by pollen, dust mites, and other allergens. A better understanding of this data might lead to improved treatments for people with this type of asthma, researchers say.

Climate Change and Asthma

Studies have shown that climate change can increase air pollutants such as ground-level ozone, fine particulates, wildfire smoke, and dust, and that these pollutants can exacerbate asthma. Climate change can also affect the production, distribution, and severity of airborne allergens.

NIEHS, NHLBI, and other NIH institutes and centers are leading the NIH Climate Change and Health Initiative. This is a cross-cutting NIH effort to reduce health threats such as asthma that can develop or worsen because of climate change. The initiative will look at these threats across the lifespan and find ways to build health resilience in individuals, communities, and nations around the world. A strategic framework for the Initiative will help guide NIH investments in this area.

An NIEHS-funded study provides examples of how extreme weather events can affect asthma outcomes. For example, as heat waves and droughts become more frequent and prolonged, the risk of large wildfires will likely increase, resulting in poor air quality that makes it more difficult to control asthma. Other climate-change events can lead to longer and more intense pollen seasons, while mold and dampness in homes may cause asthma to develop or worsen preexisting cases.

Asthma Rates and Mask – Good or Bad?

65% drop in serious asthma cases due to mask-wearing Israeli hospital reports

The Times of Israel reports that the Sheba Medical, an Israeli hospital reports 65% drop in serious asthma cases due to mask-wearing.

Here’s the 411 according to published reports:

• A study conducted by Sheba Medical Center found that the past year saw a 65 percent drop in serious asthma cases that required hospitalization.

• The drop was credited to widespread mask-wearing during the COVID-19 pandemic, which also helped decrease the spread of viruses such as the flu in the past year.

• By wearing masks, people are also less likely to suffer from seasonal allergies, as face coverings prevent pollen from flowers, trees, and grass coming into contact with the nose and mouth.

• The report follows Israel’s decision to drop the requirement to wear masks outdoors.

Israeli hospital reports 65% drop in serious asthma cases due to mask-wearing Jerusalemites wearing face masks walk in Jerusalem on February 04, 2021.
