How common are gastrointestinal symptoms in Covid-19?

FA Manian MD, MPH, , , , , , , , , , , , , , Leave a comment

Although GI symptoms such as diarrhea or nausea were initially thought to be uncommon among Covid-19 patients,1,2 more recent reports suggest that GI symptoms are relatively common.3-8

A review article found that as many as 50.0% of Covid-19 patients had diarrhea, ~30.0% had nausea, ~14.0% had gastrointestinal bleed, and 6.0% had abdominal pain.8  In a case series from New York City, ~25.0% of patients presented with diarrhea, while ~20.0% had nausea and vomiting. 9 

Some patients may have GI symptoms in the absence of any respiratory complaints.  Fecal tests for RNA  have found nearly one-third to a half of patients with Covid-19 shedding the virus, with some patients testing positive even after  respiratory specimens test negative.8 How often these patients harbor viable or infectious virus is not known, however.

Some have reported that as the severity of the disease worsens so do the GI symptoms.3 GI symptoms have also been associated with later presentation of Covid-19, higher liver enzymes and longer prothrombin time.3

Although the exact mechanism of GI symptoms in Covid-19 is unclear, direct invasion of virus is a plausible explanation. Indeed, potential targets for SARS-CoV-2 virus, the ACE2-expressing cells, have been identified in the GI tract, including the esophagus, gastric, intestinal and colonic epithelial cells.5,8

How common are gastrointestinal symptoms in Covid-19?

Key clinical pearls on the management of patients suspected of or diagnosed with Covid-19 in the outpatient setting

FA Manian MD, MPH, , , , , , , , , , , , , , , , , , , , , , , , , , , Leave a comment

Here are some key points to remember when managing patients with Covid-19 symptoms in the outpatient setting.  These points are primarily based on the CDC guidelines and the current literature. They may be particularly useful to primary care providers (PCP) who do not have ready access to Covid-19 test kits or radiographic imaging in the diagnosis of patients suspected of or diagnosed with Covid-19.

  • Isolation precautions. 1,6-7 Minimize chances of exposure by placing a facemask on the patient and placing them in an examination room with the door closed. Use standard and transmission-based precautions including contact and airborne protocols when caring for the patient. Put on an isolation gown and N95 filtering facepiece respirator or higher. Use a facemask if a respirator is not available. Put on face shield or goggles if available. Adhere to strict hand hygiene practices with the use of alcohol-based hand rub with greater than 60% ethanol or 70% isopropanol before and after all patient contact. If there is no access to alcohol-based hand sanitizers, the CDC recommends hand washing with soap and water as the next best practice.

 

  • Risk Factors.2-3 Older patients and patients with severe underlying medical conditions seem to be at higher risk for developing more serious complications from Covid-19 illness. Known risk factors for severe Covid-19 include age over 60 years, hypertension, diabetes, cardiovascular disease, chronic respiratory disease, and immunosuppression.

 

  • Symptoms.2,4,8,9 Reported illnesses have ranged from mild symptoms to severe illness and death. These symptoms may appear after a 2- to 14-day incubation period.
    • Fever at any time 88-99%
    • Cough 59-79%
    • Dyspnea 19-55%
    • Fatigue 23-70%
    • Myalgias 15%-44%
    • Sputum production 23-34%
    • Nausea or vomiting 4%-10%
    • Diarrhea 3%-10%
    • Headache 6%-14%
    • Sore throat 14%
    • Rhinorrhea/nasal congestion (4.8%)
    • Anosmia (undocumented percentage)

 

  • Treatment for mild illness.5 Most patients have mild illness and are able to recover at home. Counsel patients suspected to have Covid-19 to begin a home quarantine staying in one room away from other people as much as possible. Patients should drink lots of fluids to stay hydrated and rest. Over the counter medicines may help with symptoms. There is controversy regarding the safety of NSAIDs in Covid-19 (See related P4P pearl). Generally, symptoms last a few days and  patients get better after a week. There is no official guidance from the CDC or other reliable sources on how often a PCP should check in with a patient confirmed with Covid-19 and in quarantine. Please use good judgement and utilize telehealth capabilities via phone call, video call, etc… if possible.

 

  • Treatment for severe illness.3 Patients should be transferred immediately to the nearest hospital. If there is no transfer service available, a family member with appropriate personal protective equipment (PPE) precautions, should drive patient to nearest hospital for critical care services.

 

  • Ending home isolation. 5
    • Without testing: Patients can stop isolation without access to a test result after 3 things have happened. 1) No fever for at least 72 hours. This is 3 full days of no fever and without the use of medication that reduces fever; 2) Respiratory symptoms have improved.; and 3) At least 7 days have passed since symptoms first appeared.
    • With testing. 5 Home isolation may be ended after all of the following 3 criteria have been met: 1) No fever for at least 72 hours. This is 3 full days of no fever and without the use of medication that reduces fever; 2) Respiratory symptoms have improved; and 3) Negative results from at least 2 consecutive nasopharyngeal swab specimens collected more than 24 hours apart.

To all the healthcare providers out there, please be safe and stay healthy!

Key clinical pearls on the management of patients suspected of or diagnosed with Covid-19 in the outpatient setting

My patient with angina symptoms also complains of neck pain with left arm numbness. Could they be related?

FA Manian MD, MPH, , , , , , , , , , , , Leave a comment

Short answer, yes! Anterior chest pain associated with cervical intervertebral disk disease, ossified posterior longitudinal ligament or other spinal disorders is sometimes referred to as “cervical angina” (CA) or “pseudoangina” and is an often overlooked source of non-cardiac chest pain. 1-5

Although its exact prevalence is unknown, 1.4% to 16% of patients undergoing cervical disk surgery may have symptoms of CA. 1 Conversely, 1 study reported 5% of patients with angina pectoris having cervical nerve root pathology.5 Many patients describe their chest pain as “pressure” or crushing in quality mimicking typical cardiac ischemia chest pain, often resulting in extensive cardiac workup.  To add to the confusion, some patients even respond to nitroglycerin! One-half of patients also experience autonomic symptoms such as dyspnea, vertigo, nausea, diaphoresis, pallor, fatigue, and diploplia.1

Certain clues in the patient’s presentation should help us seriously consider the possibility of CA: 1-3

  • History of cervical radiculopathy eg, subjective upper extremity weakness or sensory changes, occipital headache or neck pain
  • Pain induced by cervical range of motion or movement of upper extremity
  • History of cervical injury or recent manual labor (eg, lifting, pulling or pushing)
  • Pain lasting greater than 30 min or less than 5 seconds and not relieved by rest
  • Positive Spurling maneuver ie, reproduction of symptoms by rotating the cervical spine toward the symptomatic side while providing a downward compression through the patient’s head

CA is often attributed to cervical nerve root compression, likely mediated by compression of C4-C8 nerve roots which also supply the sensory and motor innervation of the anterior chest wall.

Bonus Pearl: Did you know that experimental stimulation of spinothalamic tract cells in the upper thoracic and lower cervical segments have been shown to reproduce angina pain? 6
