Immune System: Is It A Guard Dog Or Wolf?

Without an immune system, we wouldn’t be here. Even the simplest creature, like bacteria, have types of defensive systems.

However, as we learned with Covid, the immune system can become mistimed, and be a detriment. Covid retards the innate immune system, and unleashes it later on when it no longer serves a useful purpose and actually damages tissue. In certain illnesses, like the common cold, most of the symptoms are actually CAUSED by the immune system.

in the case of allergies, symptoms are caused by the operation of our th2 immune system against a harmless entity, like pollen. With organ transplantation, our immune system recognizes the transplant as foreign; it has no reasoning capacity to realize that the transplanted tissue is necessary for us to live, and  to proceeds to reject the transplant.

In the case of the previous post, hydrocortisone, the prototypical shotgun that tamps down the immune system, benefited severe pneumonia.

With public health, immunizations, and a clean environment, infection is no longer the big killer is once was. Our immune system, designed to defend against a much more infectious world, is currently a real source of danger and disease.

Just like our coagulation system, once critical to stop the more frequent blood flowing in a violent world, Is now a bigger danger than ever because of our development of atherosclerotic blood vessel disease as we live longer.

Anticoagulants and anti-immunity treatments, some of them very expensive, are finding increased utility.

Please press the magnifying glass on the green field, and type in “immune system”. There are a number of previous posts of a more specific and detailed nature.

Chronic Conditions: Allergic Rhinitis (Nature)

Allergic #rhinitis is caused by IgE-mediated reactions to inhaled allergens and is one of the most common chronic conditions globally; it often co-occurs with #asthma and conjunctivitis.

INFOGRAPHIC: ‘DIFFERENCES BETWEEN COVID-19, THE FLU AND ALLERGIES (2020)

COMMENTARY:

The infographic by the allergy and asthma foundation aims to distinguish between Covid, Influenza and allergy. I would like to discuss more than symptoms. Covid and Influenza are both caused by invading infectious viruses.

Allergy is an over-response by the sensitized body to harmless proteins from the environment Covid and Influenza viruses cause direct damage to the lining membranes of the respiratory tract provoking a protective response by the body which produces inflammation in the nose and lung. Rhinitis, bronchitis and pneumonia result, depending on the site of the inflammation.

The symptoms of Allergy are far different from both Influenza and covid. ITCHING of the nose, eyes and skin is the hallmark of allergic Rhinitis, allergic conjunctivitis and Hives, respectively. Influenza or Covid Infection of the nose, eyes and airways can produce sneezing, redness, coughing and difficulty breathing, but not usually itching.

Fever is characteristic of Influenza and Covid, but not of uncomplicated Allergy. Asthma can result from either infection or allergy, but is a separate beast, caused by release of different inflammatory cytokines.

The ASTHMATIC REACTION shows itself in the BLOCKAGE of breathing of air OUT of the lung, on EXHALATION. This blockage on exhalation in asthma is heard as wheezing, a musical sound. Just ask the wheezing person to take a deep breath IN, which should be easier, and then breathe out as fast as possible, which should be slower and more difficult. Fever is not a feature of uncomplicated Asthma. Influenza and Covid.

Both produce FEVER, fatigue, aching and usually coughing. Covid has the greater linkage with Coughing, which often progresses to Shortness of breath. Both Influenza and Covid can produce a sore throat and runny nose. LOSS OF SENSE OF SMELL is unique to Covid, although if your nose is stuffy, the sense of smell can be impaired. Influenza preys on the very young, which are generally spared from Covid.

If you are careful about social distancing and wear masks in public, and get sick, Covid is more likely, since COVID IS MORE CONTAGIOUS THAN INFLUENZA. Covid protections will probably result in fewer cases of Influenza this winter.

To summarize,both the “flu” and Covid 19 are infectious conditions, vastly different from allergy, which is a derailed body defense mechanism. Any of the three can result in an asthmatic reaction, though the fever of influenza often lessens the Asthmatic response to that condition.. Covid is much more contagious and severe than influenza and can cause more widespread organ damage. Be sure to practice MASK WEARING AND SOCIAL DISTANCING.

If you have asthma and it worsens, in my opinion, this favors covid. My asthmatic patients often got better with the fever of Influenza. If you have a CHILD that gets sick, it is more likely to be Influenza than Covid.

TELEMEDICINE: A REVIEW OF 9 CONDITIONS THAT CAN BE TREATED ONLINE (VIDEO)

TELEMEDICINE is here to stay! With all its’ advantages Patients will demand It!

This video is one of the few to highlight WOMENS’ HEALTH as an appropriate field for Telehealth. A remote visit first may at least let the Doctor order some tests that will accelerate your care.

Urinary problems can also be appropriate for telemedicine; the MEDICAL HISTORY is such a VALUABLE DIAGNOSTIC TOOL!

Psychological and Psychiatric care could be completely remote, by telemedicine. The Doctor could save on expenses, and deliver care less expensively.

Distance disappears as a barrier to Consultations and second opinions. A University medical center or prestigious multi specialty Clinic are on your doorstep.

Of course, barriers remain in the form of regulations, litigation, bureaucracy, and Insurance, but these can be overcome, if the Will is there.

THE DOCTORS 101 CHRONIC SYMPTOMS & CONDITIONS #1 – THE “CHRONIC COUGH”

In my 88 years, I have had at least a dozen medical problems. Some have gone away on their own, some have been removed surgically, and a few have become CHRONIC, lasting for years, ultimately becoming a part of my life.

I have compiled a list of these and other SYMPTOMS & CONDITIONS I have seen as a physician. Over the next year, I will discuss them one by one, appending these vetted articles for further reading.

The ‘CHRONIC COUGH’ will be the first discussed.

As an Allergist, I was involved with coughing all of my adult life. If my patients did NOT have asthma, they usually coughed from mucus pouring down the back of their throat (post-nasal drip), from their allergic nasal condition (allergic rhinitis), or sometimes from the associated SINUSITIS drainage.

Asthma was a much more common cause of Chronic Cough for my Patients, sometimes theIr main problem. All asthmatic have a chronic inflammation of their breathing tubes(bronchi), and the resulting BRONCHITIS irritates the airway nerve endings, causing Cough.

Without enough narrowing of the airways to cause wheezing, this is called “cough equivalent asthma”. With the addition of airway narrowing (constriction) to the above situation, ASTHMA results.

There is added shortness of breath (dyspnea), and the cough becomes the “tight” wheezy cough of full-blown Asthma.

COPD (chronic obstructive pulmonary disease) may be a residue of long-term asthma, but commonly results from cigarette  smoking. Where loss of alveolae (air sacs) predominates, dyspnea (shortness of breath) is more common.

Where bronchial tube inflammation is more prominent, mucus and cough result. This cough is useful in clearing the mucus; a USEFUL COUGH (although my Patients did not always appreciate their friend, which could be bad enough to cause hernias or incontinence). 

Gastro-esophageal reflux is a chronic condition where stomach contents are not retained in the stomach by the G-E Sphincter ( a type of “purse-string” Gate), but spill(reflux) up, when not restrained by gravity, at NIGHT. The ACIDIC STOMACH CONTENTS burn the esophagus on the way up(heart burn), and are often aspirated into the airways during sleep, causing inflammation and COUGH.

There are many other less common CHRONIC LUNG ( pulmonary) DISEASES (conditions) such as sarcoidosis, bronchiectasis, interstitial pneumonitis, TB, and cancer, that can be diagnosed by imaging (X-Ray, etc.). Heart failure can also cause cough, as can blood pressure medication (ACE inhibitors). 

Smoking is an obvious cause; chronic smoking, chronic cough. Smokers know what is causing their cough, and usually don’t bother coming to the Doctor unless they cough up some blood, or develop one of the myriads of diseases caused by their habit.

If you have a chronic cough, check with your Primary Care Doctor, who may refer you to an Allergist or Pulmonologist. The following article will be useful to your understanding of cough, and will provide a LIST OF QUESTIONS the DOCTOR will likely ask you.
