Dupilumab specifically treats type 2 inflammation in asthma, which doesn't occur in all patients with asthma. What is the role of type 2 inflammation? How is treatment for this type of asthma different?

Type 2 inflammation is an important factor. And I would say the majority of our individuals that have asthma, and depending upon which study you look at between 50 to 80% of individuals—and you can sort of split the difference and say, right around two-thirds of individuals—have evidence for type 2 inflammation. It really depends on how you look for it and measure it.

You know, from my perspective, if I see someone who has difficult-to-manage asthma, and they don't have signs of type 2 inflammation, my first question is, "Is this really even asthma?" Because we know that the majority of individuals do have type 2 inflammation. And unfortunately, we really don't have a whole lot of great tools to identify those that don't have type 2 inflammation. So, we have these biomarkers that we can use that, including eosinophils, exhaled nitric oxide (FeNO), and some others, including sputum analysis, that we can use to identify this type 2 inflammation. And we know that inflammation is really, really paramount in driving exacerbations and driving remodeling.

A lot of the things that we see with asthma, including symptoms of cough, wheezing, shortness of breath, when patients don't have type 2 inflammation as manifest by elevated eosinophils, elevated FeNO, or if you get a little bit fancier and look at other markers, whether it be you know, a dirtier marker like IgE or allergic sensitivity, or, you know, looking at more specific tools like sputum eosinophils, then you sort of have…something that's mimicking asthma. And really, that's the approach that most of us take, primarily because all of the therapeutics that we've had including steroids, therapeutics and biologics that are currently available target type 2 inflammation.

Now, you know, asthma is a broad, heterogeneous syndrome and most of us agree that that's the case. And there are those that don't have type 2 inflammation—although I'd say a smaller percentage. And we still don't know how to adequately and accurately identify those individuals, you know, we can rule out things like COPD [chronic obstructive pulmonary disease] and chronic bronchitis, etc. But, you know, it's still a nebulous sort of area if someone does not have evidence of type 2 inflammation as whether that's truly asthma.

How has dupilumab changed the treatment space for patients with type 2 inflammation in asthma?

No, I mean, again, I think that dupilumab has really just been a game changer for us in in the asthma world. When we take care of patients with severe asthma, I think historically we would struggle with what to do with these individuals and we bounced around from, you know, oral steroids to different inhaled steroids to, you know, LAMAS [long-acting muscarinic antagonists]. And, you know, we sort of had run through different options with biologics as they became available, hoping that we would find, you know, a successful option.

And now, you know, we live in a nice time where I can sort of say to a patient, "look, I've got something for you. And I'm confident that this is going to work based on the data that's been presented to me." And so, you know, it's really an exciting time to be a respiratory specialist, whether you're an allergist or a pulmonologist based on these options.

Community-Acquired Pneumonia: Symptoms and Treatment - Verywell Health

There are several ways that you can develop pneumonia ranging from inhaling toxic substances in the workplace to unknowingly being infected by a bacteria in the hospital. Any lung infection acquired outside of the hospital setting is considered community-acquired pneumonia (CAP). Viruses and certain bacteria such as streptococcus pneumoniae (S. pneumoniae), haemophilus influenzae, and atypical bacteria—like chlamydia pneumoniae, mycoplasma pneumoniae, and Legionella species—are among the most common culprits of CAP. This article discusses the symptoms, causes, treatment, and prognosis for community-acquired pneumonia. Mongkol Chuewong / Getty Images Symptoms The clinical presentation of CAP varies wildly depending on the range. For example: Mild pneumonia is characterized by fever and a productive cough. Severe pneumonia is characterized by difficulty breathing and sepsis. Symptoms of CAP often develop quickly and are ac...

How to Decode Your Baby's Cough - Yahoo Lifestyle How to Decode Your Baby's Cough - Yahoo Lifestyle Posted: 09 Apr 2013 12:00 AM PDT A baby's cough can mean many different things, and it's not as if you can ask your baby what's wrong. Sometimes it's hard to know if you should call your doctor for advice, make an appointment, or head straight to the emergency room . Coughs are the body's way of protecting itself, explains Howard Balbi, M.D., director of pediatric infectious diseases at Nassau County Medical Center in East Meadow, New York. Coughing serves as the method the body uses to keep the airways clear, ridding the throat of phlegm, postnasal drip (nasal mucus that drips down the back of the throat), or a lodged piece of food. There are two kinds of coughs that serve this purpose: dry cough and wet cough.  Baby Dry Cough: This occurs when a baby has a cold or allergies. A dry cough helps cle...
