Role of viral infections in the development and exacerbation of asthma in children

Wheezing is a common complaint among parents of infants.  About 1 in 5 children have acute wheezing illnesses in their first two years of life.  This is important because an overwhelming majority of these wheezing illnesses are related to viruses, and are linked to asthma development.  In this month’s issue of JACI, Jartti and Gern review the role of viral infections in the development of asthma in children (J Allergy Clin Immunol 2017; 140(4): 895-906). 

They survey the viruses -rhinoviruses, respiratory syncytial viruses, and others – and how they impact the developing set of lungs.  Genetic variation and low interferon responses are two factors that increase the risk of these types of infections.  In addition, increased eosinophil counts in blood and nasal mucus and atopic eczema all increase the risk of later asthma. 

Additionally, viral infections can lead to exacerbations in children who already have asthma.  This may explain why the rates of asthma exacerbations are higher during the fall and winter, and why omalizumab, a potent medication for asthma control, may help to prevent exacerbations due to viruses like rhinovirus.  The authors conclude that these insights may allow for new strategies to help prevent and manage viral wheezing illnesses so that they don’t lead to and worsen later asthma.

  2. As a sign of gratitude for how my husband was saved from asthma , i decided to reach out to those still suffering from this.
    My husband suffered asthma and it was really tough and heartbreaking for me because he was my all and the symptoms were terrible, we tried various therapies prescribed by our neurologist but none could cure him. I searched for a cure and i saw a testimony by someone who was cured and so many other with similar body problem, and he left the contact of the doctor who had the herbal cure to asthma . I never imagined asthma has a cure not until i contacted him and he assured me my husband will be fine. I got the herbal medication he recommended and my husband used it and in one months he was fully okay even up till this moment he is so full of life. asthma has a cure and it is a herbal cure contact the doctor for more info on drwilliams098675@gmail.com on how to get the medication. Thanks for reading my story

  3. Irrespective of receiving daily oral or future injectable depot therapies, these require health care visits for medication and monitoring of safety and response. If patients are treated early enough, before a lot of immune system damage has occurred, life expectancy is close to normal, as long as they remain on successful treatment. However, when patients stop therapy, virus rebounds to high levels in most patients, sometimes associated with severe illness because i have gone through this and even an increased risk of death. The aim of “cure”is ongoing but i still do believe my government made millions of ARV drugs instead of finding a cure. for ongoing therapy and monitoring. ARV alone cannot cure HIV as among the cells that are infected are very long-living CD4 memory cells and possibly other cells that act as long-term reservoirs. HIV can hide in these cells without being detected by the body’s immune system. Therefore even when ART completely blocks subsequent rounds of infection of cells, reservoirs that have been infected before therapy initiation persist and from these reservoirs HIV rebounds if therapy is stopped. “Cure” could either mean an eradication cure, which means to completely rid the body of reservoir virus or a functional HIV cure, where HIV may remain in reservoir cells but rebound to high levels is prevented after therapy interruption.Dr Itua Herbal Medicine makes me believes there is a hope for people suffering from,Cancer,Hiv_ Aids,Herpes,Copd,Diabetes,Hepatitis,I read about him online how he cure Tasha and Tara so i contacted him on drituaherbalcenter@gmail.com even talked on whatsapps +2348149277967 believe me it was easy i drank his herbal medicine for two weeks and i was cured just like that isn't Dr Itua a wonder man? Yes he is! I thank him so much so i will advise if you are suffering from one of those diseases Pls do contact him he's a nice man.
