Case Study: What's Causing This Cough?

A new case study in which the patient, H.T. an 82-year-old Hispanic man presents to his primary care clinic with cough, malaise and confusion. How well do you know your way around a cough? Specialties Critical Case Study

Updated:  

Chief Complaint:

Provided by caregiver: "My grandfather is confused and pretty sick. He was up most of the night coughing.”

History of Present Illness:

H.T. is an 82-year-old Hispanic male who is widowed and a retired grocery store owner. His 28-year-old granddaughter lives with him. He uses a walker and takes daily walks in the neighborhood with her. He can perform most ADLs, but his granddaughter prepares his meals. He presents to the clinic with his caregiver who reports that about a week ago, Mr. T. came down with a cold and had a runny, stuffy nose. He visited the curandero and has been drinking gordolobo tea with honey, lemon and a generous dollop of tequila. He appeared to be getting better, but then several days ago he developed a cough. Over the last two days, the cough has become worse and he can't seem to catch his breath. He was confused last night and nearly fell getting out of bed.

General Appearance:

The patient's age is consistent with that reported. He is well-groomed and neat, uses a walker for ambulation and walks with a pronounced limp. He is lethargic, frail and thin oriented to self only. Patient is coughing and using accessory muscles to breathe. Appears uncomfortable and in moderate respiratory distress.

Okay, super sleuths, what are all the possible reasons for a cough? What's causing his confusion? I think the most fun way to play is to imagine you only get 5 questions. With that limit in mind, what information could you ask for that would give you the most information for a diagnosis? What labs do you want? What other diagnostic tests should we run? Ask me some questions!

All of the above. Add a cmp. If he was febrile, draw lactate & procalcitonin.

UPDATE ON MR. T!

Your first order of business is to tell the granddaughter to have Mr. T stop taking the tea, or at least to leave out the Tequila!

Use https://www.drugs.com/interaction/list/ to check drug interactions. Noting that ETOH can cause BP to drop when taken with atenolol and HCTZ. ETOH and aripiprazole can cause dizziness, confusion and drowsiness and of course taking ETOH with ASA can irritate the lining of the stomach and increase the risk for stomach ulcers.

Gordolobo tea is made with Mullein flowers. You can read more about it here https://www.drugs.com/npc/mullein.html

There isn’t a lot of information out there about interactions, dosing or side effects and minimal scientific support that it works.

Mr. T has community acquired pneumonia (CAP), but what kind? How severe is it? Does he need to go to the hospital?

Refresher - pneumonia is a common lung infection where alveoli become inflamed. They can fill with fluid, pus, and cellular debris. It can be caused by viruses, fungi, or bacteria, but it looks like Mr. T. has bacterial pneumonia, the most common type of CAP.

Bacterial vs. viral pneumonia: How to tell the difference

The two most common causes of pneumonia are bacteria and viruses. The flu is one of the most common causes of viral pneumonia in adults, though post-flu complications can also cause bacterial pneumonia. Viral pneumonia is more likely to affect healthy people with strong immune systems. Bacterial pneumonia can be more aggressive and difficult to treat than viral pneumonia. In bacterial pneumonia, there will likely be a much more visible presence of fluid in the lungs than viral pneumonia. Bacterial pneumonia is also more likely to enter the blood stream and infect other parts of the body.

What color is my mucus?

You may have read that you can tell what pathogen you’re infected with by the color of the mucus. White means a cold, yellow or green are bacterial, but that’s actually not true. Both viral and bacterial upper respiratory infections can cause similar changes to the type and coloration of nasal mucus. During a common cold, nasal mucus may start out watery and clear, then become progressively thicker and opaque, with a yellow or green tinge.

The timing of symptoms may offer a clue as to the type of germs present. Thick, colored nasal mucus more often occurs at the beginning of a bacterial illness, rather than several days into it, as occurs with a viral infection. In addition, symptoms due to a bacterial infection often last more than 10 days without improvement.

In a few cases, a bacterial infection may develop on top of a viral cold, in which case symptoms may get better and then worse again. Under these circumstances, an antibiotic may lessen the severity of symptoms and shorten the duration of the illness.

Additional Questions - PLEASE DO POST THE ANSWERS TO THESE HERE (yes, really, you can post them here):

  1. Admit to hospital for treatment?
  2. 30-day mortality probability?
  3. Any signs supporting “double pneumonia?”
  4. How many risk factors predispose this patient to pneumonia?
  5. How many clinical manifestations are consistent with pneumonia?

Try this tool to answer: the Pneumonia Severity of Illness site will calculate mortality risk and hospitalization recommendation.

This patient has pneumococcal pneumonia caused by Streptococcus pneumonia.

The most common symptoms of bacterial pneumonia are:

  • a cough with thick yellow, green, or blood-tinged mucus
  • stabbing chest pain that worsens when coughing or breathing
  • sudden onset of chills severe enough to make you shake
  • fever of 102-105°F or above (fever lower than 102°F in older persons)

Other symptoms that may follow include:

  • headache
  • muscle pain
  • breathlessness or rapid breathing
  • lethargy or severe fatigue
  • moist, pale skin
  • confusion, especially among older persons
  • loss of appetite
  • sweating

Older adults will share all the symptoms with younger adults but are much more likely to experience confusion and dizziness. Older adults may also be less likely to have a fever.

Bacteria pneumonia is caused by bacteria that works its way into the lungs and then multiplies. It can occur on its own or develop after another illness, like a cold or the flu.

Types of bacteria

Streptococcus pneumonia is the leading cause of bacterial pneumonia. It can enter your lungs through inhalation or through your bloodstream. There is a vaccination for this type.

Haemophilus influenzae is the second most common cause of bacterial pneumonia. This bacterium may live in your upper respiratory tract. It doesn’t usually cause harm or illness unless you have a weakened immune system.

Other bacteria that can cause pneumonia include:

  • Staphylococcus aureus
  • Moraxellaca tarrhalis
  • Streptococcus pyogenes
  • Neisseria meningitidis
  • Klebsiella pneumoniae

Environmental and lifestyle risk factors

  • smoking
  • working in an environment with a lot of pollution
  • living or working in a hospital setting or nursing facility
  • Medical risk factors
  • recent viral respiratory infection
  • difficulty swallowing
  • chronic lung diseases
  • weakened immune system

Age groups

People over the age of 65 and children 2 and younger are at a higher risk for developing pneumonia. Pneumonia for these groups can be life-threatening.

How is bacterial pneumonia diagnosed?

  • Auscultate lungs
  • CBC
  • Blood culture
  • Sputum culture
  • Chest X-rays

How do you treat bacterial pneumonia?

Most cases can be treated at home with antibiotics. A healthy person may recover within one to three weeks. Someone with a weakened immune system may take longer.

Hospital care

Some cases of bacterial pneumonia will require hospitalization for treatment. Young children and the elderly are more likely to need intravenous antibiotics and rehydration as well as respiratory therapy.

Complications

Without treatment, pneumonia may develop into:

  • organ failure
  • difficulty breathing
  • pleural effusion
  • lung abscess

How can you prevent bacterial pneumonia?

Bacterial pneumonia itself is not contagious, but the infection that caused bacterial pneumonia is contagious. It can spread through coughs, sneezes, and contamination on objects. Practicing good hygiene can help prevent the spread of pneumonia or the risk of catching it.

My guess for the diagnosis for the article "What's causing this cough?" is pneumonia with sepsis.
