Society of Acquired Pathogens (S.O.A.P.)


The following is an edited transcript of infectious agents seminar against human health, October, 2019:

Moderator: Thank you for taking the time out from afflicting disease to attend this seminar and welcome our latest pathogen in training, SARS-CoV-2. Viral agents and Rickettsia should take the first few rows that contain cell cultures. It is my pleasure to introduce our guest speaker,  inflicting misery on Homo sapiens for centuries, our President, Yersinia pestis.

Yersinia pestis: Thank you. For those of you who are unfamiliar with my resumé, I am responsible for bubonic, pneumonic and septic plague. Partnering with the black rat and rat flea, I have inflicted death rates of 50-80% for generations. I helped take down the Roman Empire in the 6th century by killing thousands of farmers.  Since the farmers were now not available to pay their Roman taxes to support the military, this led to the collapse of the Roman armies. My greatest hit was 1346-1353 where I took out half of the population of Europe. I started out in China, traveled with traders overland and with the shipping trade and went west, south and northwest, tightening the noose of misery on millions. I took on one of the greatest city-states at the time, Florence, and annihilated hundreds of thousands. For those Florentines that had a false sense of security and fled to the countryside, my coterie of fleas and bacilli followed them and finished them off. I rushed into Avignon, then the seat of the papacy, and inflicted so much suffering that the Pope blessed the Rhône River as a burial site. As the centuries passed and I lost some of my virulence, I came back every few generations of humans to remind them of my sordid deeds.

 Of course, I couldn’t do it alone so I’d like to introduce my fellow “partners in crime.”

Bacillus anthracis: Thank you, Yersinia. Some may say I take a backseat to the Plague but others recognize me as a formidable foe. I cause Anthrax. I received some kudos from human terrorists who used my spores to infect others through the U.S. mail in 2001. I am crafty and can infect humans through the skin, lungs and gut. Proudly,  I can kill 85% of victims within hours or days. What about those deaths in England in 1348-1349? Yes, I chipped in with Yersinia by killing cattle, transmitting my disease through eating meat and leaving my spores in burial graves. My spores can stay viable in soil for over 40 years! Now, THAT is staying power.

Moderator: We acknowledge the lesser known genera, Rickettsia and their contribution to human suffering.

Rickettsia prowazekii: I’ll be brief as I cannot stay long outside my cell culture medium. I may be intracellular but even humans acknowledge my clout: my disease is called EPIDEMIC typhus. My ride is the human louse, pediculus humanus corporis. I thrive with poverty, war and overcrowding and feel at home in endothelium, the cell that lines blood vessels. I cause rash, headache, cough, muscle pain and then progress to shock and delirium and then death. I have caused more deaths than all the wars combined. I was there during the Peloponnesian War in ancient Greece, the Thirty Years’ War and the Napoleonic Wars. In fact, I killed more of Napoleon’s troops than did the Russians. I caused misery and death during the Great Irish Potato Famine in 1846 and spread to England. The English called it the “Irish fever,” blaming the Irish instead of giving me full credit for the disease. While poverty and hygiene has improved recently and the human louse is in short supply, I jumped to the flying squirrel to cause intermittent disease in modern humans. Please be assured, I am still in the game and doing my part.

Moderator: My thanks to all of the innovative microbes that have stricken so many for so many centuries. Now, we welcome our latest entry to the world of human virulence,  an RNA virus from an unheralded family. Let’s give a warm welcome and a round of applause for SARS-CoV-2.

SARS-CoV-2:  I am humbled to take my place among the greats of infectious disease. I want to express my gratitude to our “think tank” and mammalian assistant, the bat, who has unselfishly provided incubation over the centuries to improve our infectivity.  I proudly come from the family of Coronaviruses. We have been in the human disease business for over 800 years, but have been underwhelming as we have only succeeded in causing the common cold with our first 4 family members. We showed promise in 2003 with the release of my brother, SARS-1, and a later cousin, MERS. SARS-1 had an encouraging mortality of 50% and we were packing the ICU’s in Asia. We did not plan for high transmission rates and with public health measures we were stymied early in the game. I inherited 85% of the genome and fine tuned my transmission rates. In contrast to my ancestor SARS-1, who was most infectious during severe illness, I made sure I could jump to another human even before they were experiencing my infective presence. This was the magic bullet for my success and I am honored to be nominated for rookie pathogen of the year.

Yersinia pestis: I want to thank all in participating in this important update. Let me remind you that Homo sapiens are adaptable and we must be vigilant. In Florence, after several generations of plague, they formed isolation hospitals, board of health administrators and invoked quarantining measures to restrict my spread. They finally got the tools to see some of us in 1683 (early microscope, van Leeuwenhoek). Our fellow microbes have been betraying us starting in the 20th century with penicillin (the mold Penicillium notatum), streptomycin (the bacteria Streptomyces griseus), and tetracycline (Streptomyces aureofaciens). Our machinery has been co-opted  (DNA polymerase) and our bacterial tools to prevent viral infections in us have been discovered (CRISPR technology). We can take solace in that humans have short memories and often make irrational choices and blame others that have nothing to do with their plight. But we must stay vigilant: It is never too late to mutate! Let me call this meeting adjourned and we all look forward to next year’s gathering.

Coronavirus: ICU and the Human Factor

The summer of 1979 is permanently etched into my memory. I walked into the Intensive Care Unit at U.C. San Diego Medical Center as a newly minted intern. I walked over to ICU-Bed 1 to be introduced to my first patient, a frail teen aged boy who was tethered to a ventilator. “He is day 30 with respiratory failure from disseminated coccidioidomycosis,” my internal medicine resident informed me. “He is your responsibility now, and don’t f__ it up.” An impending wave of anxiety enveloped me as I visually tracked the unending array of IV’s, feeding tube, central line, temporary pacemaker leads and monitoring equipment surrounding his bed. Over the next 6 weeks, I quickly learned that I was a small cog in the care that navigated his course away from almost certain mortality. As the credits to a movie may roll for minutes with names that do not have an apparent effect on the finished product, so too is the list of people who render care to the ICU patient. The pulmonologist, critical care specialist, critical care nurses, respiratory therapists and anesthesiologists represent a core team. Integral to their support are those that are in the supply chain providing meds, equipment (lines, pacemakers, intubation equipment, personal protective equipment, monitors, ventilators) and those that support and repair these items. Additionally, consultative services such as cardiology, infectious disease, gastroenterology, neurology, hematology, surgery and ENT to name a few, are involved with medical and surgical issues that arise from the prolonged hospital course and many complications that arise in patients that cannot provide critical organ function. Furthermore, ICU patients consume intensive utilization of laboratory and radiology service. Ethics committee members may be involved in deciding end of life and medical futility issues. Family adjustment and bereavement may also need social work and psychiatric services to cope with these psychosocial issues. The work day of the ICU is punctuated by “crisis moments” as each patient may have a life threatening arrhythmia, mucous plug in a large airway preventing oxygenation, massive gastrointestinal bleed, pneumothorax from high ventilator pressures to name a few of the “falling dominoes” of the critically ill patient.

Universal precaution implementation is, in an ideal world, best adopted in a slow, compliant fashion with a critical care or scrub nurse equivalent monitoring the provider for breaches in technique while putting on and removing personal protective equipment. In real life, emergent events require rushed donning of masks and gowns with possible gaps in the mechanical barriers. Of course, infective risks are greater with the lack of N95 respirators and the use of less protective surgical masks. Now, let’s look at the public risks of community exposure when the family equation is factored in. At least a dozen or more providers may enter an ICU bed in a given day. Most of the health care professionals are young, have families and extended families that they interface with on a daily basis. A four person household with a dozen personnel exposed to COVID-19 and a national number of 85,000 ICU beds creates a potential exponential source of infection in the community.

More masks, more providers and infrastructure are needed now. Can this be possible? Innovation in equipment, medical therapy and healthcare delivery are possible given the resiliency of Americans devoted to the well being of the United States. Is it possible? I have faith that this can be overcome. And, yes, my teenage patient  in 1979, after 30 more days in the ICU, walked out of the hospital with a smile on his face and his health intact.

Should you retire? A Cognitive Test of Retirement-Worthiness

There are plenty of retirement calculators on the internet using your financial health as barometers of retirement. For those that want to supplement your retirement decision, take the following quiz.

  1. The patient is “digitized” means digoxin rather than  an electronic medical record.
  2. You know the difference between ouabain and digitoxin.
  3. Your mentors are Ben Casey and Dr. Kildare.
  4. Your go to analgesic is Zomax.
  5. Your peptic ulcer patients all go on heavy cream (Sippy diet).
  6. You were the treating physician at the Legionaire’s conference in 1979.
  7. You still carry two or more pens “just in case.”
  8. You are comfortable with terms like “thymol turbidity” and “Wasserman testing.”
  9. On the radiology order form you search for “pneumoencephalogram.”
  10. You enter the room and are surprised nobody offers their seat to you.

Score:

10/10:  Methuselah  Doc: go straight to retirement and offer your services to a Medical History Museum.

7-9/10: Research 55 and older communities: notify your colleagues of impending obsolescence.

4-6/10: Double your CME: spend more time with millennial docs.

0-3/10: Rest easy: proclaim you’re youth in the twitterverse and toss out a few Smiley emojis. You are low on the Obsolescence curve.
