Are NSAIDS contraindicated in patients with 2019 novel Coronavirus infection (Covid-19)?

Despite recent internet reports of the association of non-steroidal anti-inflammatory drugs (NSAIDs) with worsening symptoms among patients with Covid-19 (1), firm clinical evidence to support such claims is currently lacking. However, there are some theoretical reasons why it may still be best to avoid NSAIDs in this condition due to their potential adverse impact on the innate and adaptive immune responses as well as their antipyretic properties (2-9).

 
Blunting of the innate immune response: Certain NSAIDs (eg, ibuprofen, naproxen and celecoxib) inhibit cyclooxygenase enzyme-2 (COX-2) and impair production of several pro-inflammatory cytokines important in fighting infections, such as tumor necrosis factor, interleukin 1 and 6, as well as interferon, an antiviral cytokine (2,6,8). COX-2 has been shown to be important in controlling viral replication in influenza (4). Ibuprofen has been associated with inhibitory effects on a variety of polymorphonuclear functions, including chemotaxis (2).

 
Impact on adaptive immune response: COX-2 inhibition may be associated with impaired neutralizing antibody production (3,4,8). Potential mechanisms include modulation of cytokine expression, nitric-oxide production, and antigen processing/presentation and T lymphocyte activation (3,8).

 
Antipyretic effect: NSAIDs are often given for treatment of fever which is an evolutionary host response to infection. A meta-analysis of animal studies evaluating the impact of antipyretics (including aspirin, NSAIDs, and acetaminophen) in influenza found lower survival in animals treated with antipyretics (9). Longer duration of viral shedding has also been associated with the use of aspirin or acetaminophen in rhinovirus infection (9).

 
Formal epidemiologic and experimental studies are sorely needed to evaluate the safety of NSAIDS in Covid-19.

Are NSAIDS contraindicated in patients with 2019 novel Coronavirus infection (Covid-19)?

Key clinical pearls in the medical management of hospitalized patients with coronavirus (Covid-19) infection

FA Manian MD, MPH, , , , , , , , , , , , , , , , , , , , , , , , 1 Comment

First, a shout-out to dedicated healthcare workers everywhere who have selflessly given of themselves to care for the sick during this pandemic. Thank you! Together, I know we will get through it!

Although our understanding of Covid-19 infection is far from complete, in the spirit of clarity and brevity of my posts on Pearls4Peers, here are some key points I have gleaned from review of existing literature and the CDC that may be useful as we care for our hospitalized patients with suspected or confirmed Covid-19 infection.

  • Isolation precautions.1 Per CDC, follow a combination of airborne (particularly when aerosol generating procedures is anticipated, including nebulizer treatment) and contact precaution protocols. Routinely use masks or respirators, such as N-95s (subject to local availability and policy) and eye protection. Don gowns (subject to local availability and policy) and gloves and adhere to strict hand hygiene practices.

 

  • Diagnostic tests1-9
    • Laboratory tests. Routine admission labs include CBC, electrolytes, coagulation panels and liver and renal tests. Other frequently reported labs include LDH, C-reactive protein (CRP) and procalcitonin. Testing for high sensitivity troponin I has also been performed in some patients, presumably due to concern over ischemic cardiac injury or myocarditis.2 Check other labs as clinically indicated.
    • Chest radiograph/CT chest. One or both have been obtained in virtually all reported cases with CT having higher sensitivity for detection of lung abnormalities.
    • EKG. Frequency of checking EKGs not reported in many published reports thought 1 study reported “acute cardiac injury” in some patients, based in part on EKG findings.4 Suspect we will be checking EKGs in many patients, particularly those who are older or are at risk of heart disease.
    • Point-of-care ultrasound (POCUS). This relatively new technology appears promising in Covid-19 infections, including in rapid assessment of the severity of pneumonia or ARDS at presentation and tracking the evolution of the disease. 9 Don’t forget to disinfect the probe between uses!

 

  • Treatment 1-8
    • Specific therapies are not currently available for treatment of Covid-19 infections, but studies are underway.
    • Supportive care includes IV fluids, 02 supplementation and nutrition, as needed. Plenty of emotional support for patients and their families will likely be needed during these times.
    • Antibiotics have been used in the majority of reported cases, either on admission or during hospitalization when superimposed bacterial pneumonia or sepsis could not be excluded.
      • Prescribe antibiotics against common community-acquired pneumonia (CAP) pathogens, including those associated with post-viral/influenza pneumonia such as Streptococcus pneumoniae (eg, ceftriaxone), and Staphylococcus aureus (eg, vancomycin or linezolid if MRSA is suspected) when concurrent CAP is suspected.
      • Prescribe antibiotics against common hospital-acquired pneumonia (HAP) (eg, vancomycin plus cefepime) when HAP is suspected.
    • Corticosteroids should be avoided because of the potential for prolonging viral replication, unless indicated for other reasons such as COPD exacerbation or septic shock. 1
    • Monitor for deterioration in clinical status even when your hospitalized patient has relatively minor symptoms. This is because progression to lower respiratory tract disease due to Covid-19 often develops during the 2nd week of illness (average 9 days).
    • ICU transfer may be necessary in up to 30% of hospitalized patients due to complications such as ARDS, secondary infections, and multi-organ failure.

 

Again, thank you for caring for the sick and be safe! Feel free to leave comments or questions.

Although the Covid-19 pandemic is continuing to evolve and our knowledge of its epidemiology and pathophysiology is still far from complete, you may find the following pearls based on published literature to date useful when discussing this disease with your colleagues or the public. 1-11

  • Age group: Primarily an adult disease. Children (< 15-year-old) account for only a minority of symptomatic patients (<1%); ~50% of patients are between 15-49 years of age with 15% in the ≥ 65 year group. 1
  • Incubation period: A bit longer than seasonal flu. Median 4.0 days (IQR 2.0-7.0 days); an upper range up to 24 days has also been reported. In contrast, for seasonal flu the median incubation period is shorter (median 2.0 days, 1.0-7.0 days. 1,4,11
  • Transmission: Contact, droplet, and possibly airborne. On average each person may transmit Covid-19 virus to 2-3 other persons (vs <2 people for seasonal flu). Unlike SARS or MERS, but more akin to the seasonal flu, asymptomatic persons may also be able to transmit the disease. 4,5,11
  • Comorbid conditions (eg, diabetes, hypertension, COPD…): Present in about 1/3 of reported patients. 1
  • Symptoms 1,5
    • ~80% of patients may be either asymptomatic or have mild disease
    • Fever may be absent in ~50% of patients on presentation but will eventually develop in ~90% of hospitalized patients
    • Cough (2/3 dry) is present in majority (~80%) of cases
    • Rhinorrhea is uncommon (<10%), in contrast to the seasonal influenza
    • GI symptoms (nausea/vomiting/diarrhea) are uncommon by some reports(<10%), but not by others (>30.0%). 12
    • May take 9-12 days from onset of symptoms to severe disease
  • Labs 1
    • Lymphopenia is common (up to ~80%)
    • Abnormal liver function (AST and ALT) is found in about 1/3 of patients
    • C-reactive protein (CRP) is usually elevated (~80% of severe cases)
    • Procalcitonin is usually normal
  • Treatment: Supportive for now. Candidate drugs include remdesivir, lopinavir/ritonavir, chloroquine phosphate, ribavirin and several others.4
  • Mortality: Reported mortality among mostly symptomatic hospitalized cases is ~2.0% (0.9% without comorbidities, 5-10% in those with comorbidities, 50% among critically ill). Overall mortality rates will likely drop as more patients without symptoms or with mild disease are tested. In contrast, 2 other coronavirus diseases, SARS and MERS, have mortality rates of ~9.0% and 36.0%, respectively. 1,4,5

 

Bonus pearl: Did you know that, Covid-19-infected patients shed the virus in their nasopharyngeal secretions on the average for 12 days, some as long as 24 days?3
