ACC issues guidance on cardiac implications of coronavirus

Article Type
Changed

The American College of Cardiology on Feb. 13, 2020, released a clinical bulletin that aims to address cardiac implications of the current epidemic of the novel coronavirus, now known as COVID-19.

The bulletin, reviewed and approved by the college’s Science and Quality Oversight Committee, “provides background on the epidemic, which was first reported in late December 2019, and looks at early cardiac implications from case reports,” the ACC noted in a press release. “It also provides information on the potential cardiac implications from analog viral respiratory pandemics and offers early clinical guidance given current COVID-19 uncertainty.”

The document looks at some early cardiac implications of the infection. For example, early case reports suggest patients with underlying conditions are at higher risk of complications or mortality from the virus, with up to 50% of hospitalized patients having a chronic medical illness, the authors wrote.

About 40% of hospitalized patients confirmed to have the virus have cardiovascular or cerebrovascular disease, they noted.

In a recent case report on 138 hospitalized COVID-19 patients, they noted, 19.6% developed acute respiratory distress syndrome, 16.7% developed arrhythmia, 8.7% developed shock, 7.2% developed acute cardiac injury, and 3.6% developed acute kidney injury. “Rates of complication were universally higher for ICU patients,” they wrote.

“The first reported death was a 61-year-old male, with a long history of smoking, who succumbed to acute respiratory distress, heart failure, and cardiac arrest,” the document noted. “Early, unpublished first-hand reports suggest at least some patients develop myocarditis.”

Stressing the current uncertainty about the virus, the bulletin provides the following clinical guidance:

  • COVID-19 is spread through droplets and can live for substantial periods outside the body; containment and prevention using standard public health and personal strategies for preventing the spread of communicable disease remains the priority.
  • In geographies with active COVID-19 transmission (mainly China), it is reasonable to advise patients with underlying cardiovascular disease of the potential increased risk and to encourage additional, reasonable precautions.
  • Older adults are less likely to present with fever, thus close assessment for other symptoms such as cough or shortness of breath is warranted.
  • Some experts have suggested that the rigorous use of guideline-directed, plaque-stabilizing agents could offer additional protection to cardiovascular disease (CVD) patients during a widespread outbreak (statins, beta-blockers, ACE inhibitors, acetylsalicylic acid); however, such therapies should be tailored to individual patients.
  • It is important for patients with CVD to remain current with vaccinations, including the pneumococcal vaccine, given the increased risk of secondary bacterial infection; it would also be prudent to receive vaccination to prevent another source of fever which could be initially confused with coronavirus infection.
  • It may be reasonable to triage COVID-19 patients according to the presence of underlying cardiovascular, respiratory, renal, and other chronic diseases for prioritized treatment.
  • Providers are cautioned that classic symptoms and presentation of acute MI may be overshadowed in the context of coronavirus, resulting in underdiagnosis.
  • For CVD patients in geographies without widespread COVID-19, emphasis should remain on the threat from influenza, the importance of vaccination and frequent handwashing, and continued adherence to all guideline-directed therapy for underlying chronic conditions.
  • COVID-19 is a fast-moving epidemic with an uncertain clinical profile; providers should be prepared for guidance to shift as more information becomes available.

An epidemic of fear and misinformation

Article Type
Changed

As I write this, the 2019 novel coronavirus* continues to spread, exceeding 59,000 cases and 1,300 deaths worldwide. With it spreads fear. In the modern world of social media, misinformation spreads even faster than disease.

Delpixel/Shutterstock

The news about a novel and deadly illness crowds out more substantial worries. Humans are not particularly good at assessing risk or responding rationally and consistently to it. Risk is hard to fully define. If you look up “risk” in Merriam Webster’s online dictionary, you get the simple definition of “possibility of loss or injury; peril.” If you look up risk in Wikipedia, you get 12 pages of explanation and 8 more pages of links and references.

People handle risk differently. Some people are more risk adverse than others. Some get a pleasurable thrill from risk, whether a slot machine or a parachute jump. Most people really don’t comprehend small probabilities, with tens of billions of dollars spent annually on U.S. lotteries.

Because 98% of people who get COVID-19 are recovering, this is not an extinction-level event or the zombie apocalypse. It is a major health hazard, and one where morbidity and mortality might be assuaged by an early and effective public health response, including the population’s adoption of good habits such as hand washing, cough etiquette, and staying home when ill. But fear, discrimination, and misinformation may do more damage than the virus itself.

Three key factors may help reduce the fear factor.

One key factor is accurate communication of health information to the public. This has been severely harmed in the last few years by the promotion of gossip on social media, such as Facebook, within newsfeeds without any vetting, along with a smaller component of deliberate misinformation from untraceable sources. Compare this situation with the decision in May 1988 when Surgeon General C. Everett Koop chose to snail mail a brochure on AIDS to every household in America. It was unprecedented. One element of this communication is the public’s belief that government and health care officials will responsibly and timely convey the information. There are accusations that the Chinese government initially impeded early warnings about COVID-19. Dr. Koop, to his great credit and lifesaving leadership, overcame queasiness within the Reagan administration about issues of morality and taste in discussing some of the HIV information. Alas, no similar leadership occurred in the decade of the 2010s when deaths from the opioid epidemic in the United States skyrocketed to claim more lives annually than car accidents or suicide.

Dr. Kevin T. Powell

A second factor is the credibility of the scientists. Antivaxxers, climate change deniers, and mercenary scientists have severely damaged that credibility of science, compared with the trust in scientists 50 years ago during the Apollo moon shot.

A third factor is perspective. Poor journalism and clickbait can focus excessively on the rare events as news. Airline crashes make the front page while fatal car accidents, claiming a hundred times more lives annually, don’t even merit a story in local media. Someone wins the lottery weekly but few pay attention to those suffering from gambling debts.

Influenza is killing many times more people than the 2019 novel coronavirus, but the news is focused on cruise ships. In the United States, influenza annually will strike tens of millions, with about 10 per 1,000 hospitalized and 0.5 per 1,000 dying. The novel coronavirus is more lethal. SARS (a coronavirus epidemic in 2003) had 8,000 cases with a mortality rate of 96 per 1,000 while the novel 2019 strain so far is killing about 20 per 1,000. That value may be an overestimate, because there may be a significant fraction of COVID-19 patients with symptoms mild enough that they do not seek medical care and do not get tested and counted.

For perspective, in 1952 the United States reported 50,000 cases of polio (meningitis or paralytic) annually with 3,000 deaths. As many as 95% of cases of poliovirus infection have no or mild symptoms and would not have been reported, so the case fatality rate estimate is skewed. In the 1950s, the United States averaged about 500,000 cases of measles per year, with about 500 deaths annually for a case fatality rate of about 1 per 1,000 in a population that was well nourished with good medical care. In malnourished children without access to modern health care, the case fatality rate can be as high as 100 per 1,000, which is why globally measles killed 142,000 people in 2018, a substantial improvement from 536,000 deaths globally in 2000, but still a leading killer of children worldwide. Vaccines had reduced the annual death toll of polio and measles in the U.S. to zero.

In comparison, in this country the annual incidences are about 70,000 overdose deaths, 50,000 suicides, and 40,000 traffic deaths.

Reassurance is the most common product sold by pediatricians. We look for low-probability, high-impact bad things. Usually we don’t find them and can reassure parents that the child will be okay. Sometimes we spot a higher-risk situation and intervene. My job is to worry professionally so that parents can worry less.

COVID-19 worries me, but irrational people worry me more. The real enemies are fear, disinformation, discrimination, and economic warfare.

Two new Novel Coronavirus cases confirmed among quarantined U.S. patients

Article Type
Changed

The Centers for Disease Control and Prevention announced two new patients now have the 2019 Novel Coronavirus (2019-nCoV), bringing the case total in the United States to 15.

The 14th case was discovered in California among a group of people under federal quarantine after returning from the Hubei Province in China. That patient was on a U.S. State Department–chartered flight that arrived in the United States on Feb. 7.

The 15th case was discovered in Texas among a group of people who also are under federal quarantine. That patient arrived on a State Department–chartered flight that arrived on Feb. 7. It is the first person in Texas that has tested positive for 2019-nCoV.

CDC said in a statement announcing the Texas case that there “will likely be additional cases in the coming days and weeks, including among other people recently returned from Wuhan.” Officials noted that more than 600 people who have returned as part of State Department–chartered flights are currently under that 14-day quarantine.

The agency is preparing for more widespread cases of 2019-nCoV.

Nancy Messonnier, MD, director of the CDC National Center for Immunization and Respiratory Diseases, said that containment has been the early focus for the agency.

“The goal of the measures we have taken to date are to slow the introduction and impact of this disease in the United States, but at some point, we are likely to see community spread in the U.S.,” Dr. Messonnier said during a Feb. 12 teleconference with reporters. She added that the federal response will change over time as the virus spreads.

Dr. Messonnier noted that public health officials are planning for the increased demands that a wider outbreak of 2019-nCov would place on the health care delivery system, including ensuring an adequate supply of medical equipment.

Pathways to new therapeutic agents for human coronaviruses

Article Type
Changed

No specific treatment is currently available for human coronaviruses to date, but numerous antiviral agents are being identified through a variety of approaches, according to Thanigaimalai Pillaiyar, PhD, and colleagues in a review published in Drug Discovery Today.

Using the six previously discovered human coronaviruses – human CoV 229E (HCoV-229E), OC43 (HCoV-OC43), NL63 (HCoV-NL63), HKU1 (HCoV-HKU1); severe acute respiratory syndrome (SARS) CoV; and Middle East respiratory syndrome (MERS) CoV – the investigators examined progress in the use and development of therapeutic drugs, focusing on the potential roles of virus inhibitors.

“Research has mainly been focused on SARS- and MERS-CoV infections, because they were responsible for severe illness when compared with other CoVs,” Dr. Pillaiyar, of the department of pharmaceutical and medicinal chemistry at the University of Bonn (Germany), and colleagues wrote.

2019-nCov has been linked genomically as most closely related to SARS, and the Coronavirus Study Group of the International Committee on Virus Taxonomy, which has the responsibility for naming viruses, has designated the new virus SARS-CoV-2.
 

Examining extant drugs

The first approach to identifying possible antiviral agents reevaluates known, broadly acting antiviral drugs that have been used for other viral infections or other indications. The initial research into coronavirus therapeutics, in particular, has examined current antiviral therapeutics for their effectiveness against both SARS-CoV and MERS-CoV, but with mixed results.

For example, in a search of potential antiviral agents against CoVs, researchers identified four drugs – chloroquine, chlorpromazine, loperamide, and lopinavir – by screening drug libraries approved by the Food and Drug Administration. They were all able to inhibit the replication of MERS-CoV, SARS-CoV, and HCoV-229E in the low-micromolar range, which suggested that they could be used for broad-spectrum antiviral activity, according to Dr. Pillaiyar and colleagues.

Other research groups have also reported the discovery of antiviral drugs using this drug-repurposing approach, which included a number of broad-spectrum inhibitors of HCoVs (lycorine, emetine, monensin sodium, mycophenolate mofetil, mycophenolic acid, phenazopyridine, and pyrvinium pamoate) that showed strong inhibition of replication by four CoVs in vitro at low-micromolar concentrations and suppressed the replication of all CoVs in a dose-dependent manner. Findings from in vivo studies showed lycorine protected mice against lethal HCoV-OC43 infection.

Along with the aforementioned drugs, a number of others have also shown potential usefulness, but, as yet, none has been validated for use in humans.
 

Developing new antivirals

The second approach for anti-CoV drug discovery involves the development of new therapeutics based on the genomic and biophysical understanding of the individual CoV in order to interfere with the virus itself or to disrupt its direct metabolic requirements. This can take several approaches.

MERS-CoV and SARS-CoV PL protease inhibitors

Of particular interest are antiviral therapies that attack papain-like protease, which is an important target because it is a multifunctional protein involved in proteolytic deubiquitination and viral evasion of the innate immune response. One such potential therapeutic that takes advantage of this target is disulfiram, an FDA-approved drug for use in alcohol-aversion therapy. Disulfiram has been reported as an allosteric inhibitor of MERS-CoV papain-like protease. Numerous other drug categories are being examined, with promising results in targeting the papain-like protease enzymes of both SARS and MERS.

 

 

Replicase inhibitors

Helicase (nsP13) protein is a crucial component required for virus replication in host cells and could serve as a feasible target for anti-MERS and anti-SARS chemical therapies, the review authors wrote, citing as an example, the recent development of a small 1,2,4-triazole derivative that inhibited the viral NTPase/helicase of SARS- and MERS-CoVs and demonstrated high antiviral activity and low cytotoxicity.

Membrane-bound viral RNA synthesis inhibitors

Antiviral agents that target membrane-bound coronaviral RNA synthesis represent a novel and attractive approach, according to Dr. Pillaiyar and colleagues. And recently, an inhibitor was developed that targets membrane-bound coronaviral RNA synthesis and “showed potent antiviral activity of MERS-CoV infection with remarkable efficacy.”

Host-based, anti-CoV treatment options

An alternate therapeutic tactic is to bolster host defenses or to modify host susceptibilities to prevent virus infection or replication. The innate interferon response of the host is crucial for the control of viral replication after infection, and the addition of exogenous recombinant interferon or use of drugs to stimulate the normal host interferon response are both potential therapeutic avenues. For example, nitazoxanide is a potent type I interferon inducer that has been used in humans for parasitic infections, and a synthetic nitrothiazolyl-salicylamide derivative was found to exhibit broad-spectrum antiviral activities against RNA and DNA viruses, including some coronaviruses.

Numerous other host pathways are being investigated as potential areas to enhance defense against infection and replication, for example, using inhibitors to block nucleic acid synthesis has been shown to provide broad-spectrum activity against SARS-CoV and MERS-CoV.

One particular example is remdesivir, a novel nucleotide analog antiviral drug, that was developed as a therapy for Ebola virus disease and Marburg virus infections. It was later shown to provide “reasonable antiviral activity against more distantly related viruses, such as respiratory syncytial virus, Junin virus, Lassa fever virus, and MERS-CoV,” the authors wrote.

Also of interest regarding remdesivir’s potential broad-spectrum use is that it has shown potent in vitro “antiviral activity against Malaysian and Bangladesh genotypes of Nipah virus (an RNA virus, although not a coronavirus, that infects both humans and animals) and reduced replication of Malaysian Nipah virus in primary human lung microvascular endothelial cells by more than four orders of magnitude,” Dr. Pillaiyar and colleagues added. Of particular note, all remdesivir-treated, Nipah virus–infected animals “survived the lethal challenge, indicating that remdesivir represents a promising antiviral treatment.”

In a press briefing earlier this month, Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, reported that a randomized, controlled, phase 3 trial of the antiviral drug remdesivir is currently underway in China to establish whether the drug would be an effective and safe treatment for adults patients with mild or moderate 2019 Novel Coronavirus (2019-nCoV) disease.

“Our increasing understanding of novel emerging coronaviruses will be accompanied by increasing opportunities for the reasonable design of therapeutics. Importantly, understanding this basic information about CoV protease targets will not only aid the public health against SARS-CoV and MERS-CoV but also help in advance to target new coronaviruses that might emerge in the future,” the authors concluded.

Dr. Pillaiyar and colleagues reported that they had no financial conflicts of interest.

No specific treatment is currently available for human coronaviruses to date, but numerous antiviral agents are being identified through a variety of approaches, according to Thanigaimalai Pillaiyar, PhD, and colleagues in a review published in Drug Discovery Today.

2019-nCoV outbreak: A few lessons learned for pediatric practices

Article Type
Changed

 

In late January, signs were posted in all of the offices in our faculty medical practice building.

Combined with current worldwide health concerns and flu season, we are now asking all patients two questions:

1. Do you have a fever, cough or shortness of breath?

2. Have you traveled to China in the last 2 weeks, or have you had contact with someone who has and who now is sick?

CDC/ Dr. Fred Murphy; Sylvia Whitfield

Similar signs appeared in medical offices and EDs across the city. Truth be told, when the signs first went up, some thought it was an overreaction. I practice in a city in the Southeast that is not a port of entry and has no scheduled international passenger flights. Wuhan City, China and the threat of 2019 novel coronavirus (2019-nCoV) seemed very far away.

As the international tally of cases has grown, so have local concerns.

Hopefully, proactive public health measures to care for the few individuals currently infected in the United States and appropriately assessing individuals arriving from mainland China will prevent widespread circulation of 2019-nCoV here. If this is the case, most of us likely will never see a case of the virus. Still, there are important lessons to be learned from current preparedness efforts.

A travel history is important. Public health authorities long have emphasized the importance of a travel history. Several years ago, during the height of concern over the spread of Ebola, the health care systems in which I practice asked everyone about travel to West Africa as soon as they approached the registration desk. In the intervening years, asking about a travel history largely was delegated to providers, and I suspect it largely was driven by patient presentation. Child presenting with 10 days of fever? The clinician likely took a travel history. Child presenting for runny nose, ear ache, or rash? Maybe not. With more consistent screening, we are learning how frequently our patients and their families do travel, and that is helping us expand our differential diagnosis.
 

 

 

We need to practice cough etiquette. Patients who endorse respiratory symptoms as part of 2019 n-CoV screening are handed a mask. Those who have traveled to China in the last 14 days are promptly escorted to an exam room. In truth, we should be following cough etiquette and offering all patients with respiratory symptoms a mask. Heightened awareness of this practice may help prevent the spread of much more common viruses such as influenza. Reliable processes to recognize and rapidly triage patients with an infectious illness are critically important in ambulatory settings, and now we have an opportunity to trial and improve these processes. No one wants a child with measles or chicken pox to sit in the waiting room!

Dr. Kristina A. Bryant

 

Offices must stock personal protective equipment to comply with standard precautions. The recommended PPE when caring for a patient with 2019 n-CoV includes a gown, gloves, mask (n95 or PAPR if available), and eye protection, such as a face shield or goggles. An initial survey of PPE supplies locally revealed of shortage of PPE for eye protection in some offices. Eye protection should be readily available in pediatric and other primary care offices because it must be used as part of standard precautions during procedures likely to generate droplets of blood or body fluids. Examples of common procedures that require eye protection include swabbing the nasopharynx to obtain a specimen for respiratory virus testing or swabbing the throat to test for group A streptococcus.

We should use diagnostic testing judiciously. Over the last couple of weeks, we’ve had a couple of patients who wanted to be tested for 2019 n-CoV but did not meet person under investigation (PUI) criteria. Public health authorities, who must approve all 2019 n-CoV testing, said no. This is enforced diagnostic stewardship, but it is a reminder that, when a diagnostic test is performed in a person with a low likelihood of disease, there is a risk of a false-positive result. What if we applied this principle to tests we send routinely? We would send fewer urine cultures in patients with normal urinalyses and stop testing infants for Clostridioides difficile.

Frontline providers must partner with public health colleagues during outbreaks. Providers have been instructed to immediately notify local or state health departments when a patient is suspected of having 2019 n-CoV specifically because the PUI criteria are met. This notification was crucial in diagnosing the first cases of 2019 n-CoV in the United States. Nine of the first 11 U.S. cases were in travelers from Wuhan, and according to the Centers for Disease Control and Prevention, eight of these “were identified as a result of patients seeking clinical care for symptoms and clinicians connecting with the appropriate public health systems.” Locally, daytime and after hours phone numbers for the health department have been posted in offices across our health care system. The state health department is hosting well-attended webinars to provide updates and answer questions from clinicians. We may never have a case of 2019 n-CoV in Kentucky, but activities like these build relationships between providers and our colleagues in public health, strengthening infrastructure and the capacity to respond to future outbreaks. I suspect the same is true in many other communities.

Dr. Bryant is a pediatrician specializing in infectious diseases at the University of Louisville (Ky.) and Norton Children’s Hospital, also in Louisville. She said she had no relevant financial disclosures. Email her at pdnews@mdedge.com.

Over the last couple of weeks, we’ve had a couple of patients who wanted to be tested for 2019 n-CoV but did not meet person under investigation (PUI) criteria. Public health authorities, who must approve all 2019 n-CoV testing, said no. This is enforced diagnostic stewardship, but it is a reminder that, when a diagnostic test is performed in a person with a low likelihood of disease, there is a risk of a false-positive result. What if we applied this principle to tests we send routinely? We would send fewer urine cultures in patients with normal urinalyses and stop testing infants for Clostridioides difficile.

Frontline providers must partner with public health colleagues during outbreaks. Providers have been instructed to immediately notify local or state health departments when a patient is suspected of having 2019 n-CoV specifically because the PUI criteria are met. This notification was crucial in diagnosing the first cases of 2019 n-CoV in the United States. Nine of the first 11 U.S. cases were in travelers from Wuhan, and according to the Centers for Disease Control and Prevention, eight of these “were identified as a result of patients seeking clinical care for symptoms and clinicians connecting with the appropriate public health systems.” Locally, daytime and after hours phone numbers for the health department have been posted in offices across our health care system. The state health department is hosting well-attended webinars to provide updates and answer questions from clinicians. We may never have a case of 2019 n-CoV in Kentucky, but activities like these build relationships between providers and our colleagues in public health, strengthening infrastructure and the capacity to respond to future outbreaks. I suspect the same is true in many other communities.

CDC confirms 13th case of coronavirus in U.S.

Article Type
Changed

The Centers for Disease Control and Prevention announced the number of confirmed cases of the 2019 Novel Coronavirus (2019-nCoV) in the United States has reached 13.

Dr. Anne Schuchat

The latest case, announced Feb. 11, 2020, by the CDC, was in a person in California who was previously under federal quarantine because the patient had traveled to Wuhan, China.

The CDC is currently looking into who the patient may have come in contact with to understand the potential for further spread of the coronavirus.

“The contact investigation is ongoing,” CDC principal deputy director Anne Schuchat, MD, said during a Feb. 11 press conference to provide an update on coronavirus containment activities being taken by the CDC.

Dr. Schuchat also addressed issues related to the laboratory test, as the patient in California was initially thought to be negative for the coronavirus.

“With other cases around the country that we are evaluating, we have been doing serial tests to understand whether they are still infectious” and to gather other information about how results change over time, Dr. Schuchat said.

She noted that the CDC does not “have as much information as we would like on the severity of the virus,” noting that there are many cases in China with severe reactions, while the 13 cases in the United States represent a much more mild reaction to the virus so far.

With the latest case in California, she noted that there was “probably a mix-up and the original test wasn’t negative,” although she did not elaborate on what the nature of the mix-up was, stating that was all the information that she had.

In general, Dr. Schuchat touted the actions taken by the CDC and the federal government focused primarily on containing the spread of the virus in the United States, including the implementation of travel advisories, quarantining passengers returning from China, as well as the new test kits that are being distributed by the agency across the nation and around the world. She also mentioned CDC staff are being deployed around the world to monitor the spreading of the disease and highlighted the outreach efforts to keep the public informed.

Dr. Schuchat highlighted the fact that, of the 13 cases in the United States, 11 were with patients that were in Wuhan, and only 2 were because of close contact with a patient, something that she attributed to the actions being taken.

She also noted that cases in the United States have not been as severe as they have been in China, where deaths have been attributed to the coronavirus outbreak. She added that there have been only two deaths outside of mainland China attributed to the coronavirus.

“Some of the steps the CDC has taken have really put us in better shape should widespread transmission occur in the United States,” she said.

Dr. Schuchat also highlighted that the first charter flight of people quarantined after returning from Wuhan have reached the 14-day milestone and should be on their way home beginning today.

Screen pregnant women with suspected 2019-nCoV infection

Screen, test, treat pregnant patients with severe respiratory illness
Article Type
Changed

 

It is too early yet to explicitly determine the effects of the Novel Coronavirus (2019-nCoV) on pregnant women and their fetuses. This is a critical concern, because members of the coronavirus family, which have been responsible for previous outbreaks of severe acute respiratory syndrome (SARS-CoV) and Middle East respiratory syndrome (MERS-CoV), have demonstrated their ability to cause severe complications during pregnancy, according to researchers.

The SARS virus outbreak and the more recent MERS virus outbreak provide the best available models with which to examine the potential impact of 2019-nCoV on pregnancy, according to a letter published online in the Lancet.

Twelve pregnant women were infected with SARS-CoV during the 2002-2003 pandemic. Three (25%) of these women died during pregnancy. Overall, four of seven women had a miscarriage in the first trimester. In the second or third trimester, two out of five women had fetal growth restriction, and four of the five had preterm birth (one case was spontaneous and three were induced because of the maternal condition), according to corresponding author David Baud, MD, PhD, of the maternal-fetal and obstetrics research unit at Lausanne (Switzerland) University Hospital, and colleagues.

A review of 11 pregnant women infected with the virus showed that 10 women (91%) presented with adverse outcomes. Six (55%) neonates were admitted to the ICU; three (27%) died. Two neonates were delivered prematurely because their mothers developed severe respiratory failure.

Because 2019-nCov has a potential for similar behavior, “we recommend systematic screening of any suspected 2019-nCoV infection during pregnancy. If 2019-nCoV infection during pregnancy is confirmed, extended follow-up should be recommended for mothers and their fetuses,” concluded Dr. Baud and colleagues.

Dr. Baud and associates are known for their previous research on the impacts of the Zika virus on pregnancy. They reported having no competing interests.

Body

The coronavirus has been spreading rapidly in China, and recently, international cases have been identified, including within the United States. As the article by Locher et al. suggests, mechanical, physiological, and immune adaptations in pregnancy leave pregnant women at risk of severe complications from respiratory illnesses.
 
Obstetricians need to be prepared to screen, test, and promptly treat pregnant women with any severe respiratory illness to reduce maternal and perinatal morbidity. At this time, the Centers for Disease Control and Prevention advises that any patient with fever and signs of a lower respiratory infection, as well as an epidemiologic risk factor (such as recent travel to China), should be considered at risk for the coronavirus. Samples are collected and sent to the CDC as testing can be done only at the CDC at this time. Please refer to the CDC website for up-to-date guidance for health care professionals.

Unfortunately, there is no specific treatment for coronavirus. Clinical management includes prompt implementation of recommended infection prevention and control measures. Supportive management of complications, including fever reduction and advanced organ support, should be provided as necessary.

While coronavirus is a terrifying potential threat, it’s worth mentioning that, for most pregnant women, a much more likely threat is influenza. Pregnant women with influenza virus infection are at increased risk for progression to pneumonia, ICU admission, preterm delivery, and maternal death. The influenza vaccine can help reduce these risks, and we should continue to encourage vaccination for all pregnant women. Prompt treatment is important! Treatment within 48 hours of the onset of symptoms is ideal, but treatment should not be withheld if the ideal window is missed.
 
Finally, don’t forget to remind your pregnant patients to avoid close contact with sick family members and friends, wash hands frequently, and call the doctor’s office with any sign of a flu-like illness!

Remdesivir under study as treatment for novel coronavirus

Article Type
Changed

 

A randomized, controlled trial of Gilead’s antiviral drug remdesivir is currently underway in China in hopes that it will be an effective treatment for the 2019 Novel Coronavirus (2019-nCoV).



“What they’re looking at is the effect of this drug -- either the drug plus standard of care versus standard of care alone,” Anthony S. Fauci, MD, reported Feb. 7 during a press briefing held by members of President Trump’s Coronavirus Task Force. “I think pretty soon we are going to get a definitive answer, whether one of these among several drugs works.”

Dr. Fauci, director of the National Institute of Allergy and Infectious Diseases, added that several organizations and individual investigators are developing vaccines for 2019-nCoV. In one such effort, the National Institutes of Health is working with Moderna Inc. to develop a vaccine built on a messenger RNA platform. “One of the first steps is to successfully get that [novel coronavirus] gene and insert it into the messenger RNA platform successfully and allow it to express proteins,” Dr. Fauci explained. “We’ve succeeded in that. The next [step] is to put it in a mouse animal model to induce immunogenicity, and to get the company to make [gold nanoparticle] products. All of those have been successfully implemented. There have been no glitches so far. If that continues, we will be in Phase 1 trials in people within the next two-and-a-half months.”

In another development on the same day, Robert R. Redfield, MD, director of the Centers for Disease Control and Prevention, announced that Heath & Human Services issued an interim final rule to amend foreign quarantine regulations in the wake of the public health threat posed by the 2019-nCoV. “This will enable CDC to collect certain contact information data regarding airline passengers and crew when they arrive from other countries. . .and may be exposed to communicable disease,” Dr. Redfield said. “This action is part of our multi-layered approach to the U.S. response and demonstrates our commitment to take all necessary actions to protect the American people.”

According to Alex Azar, secretary of Health and Human Services, and chair of President Trump’s Coronavirus Task Force, there are 12 confirmed cases of the novel coronavirus in the United States, including two cases of transmission to people who had not recently been in China. “Although the virus represents a potentially very serious public health threat, and we expect to continue seeing more cases here, the immediate risk to the American public is low at this time,” Mr. Azar said. “We are working as quickly as possible on the many unanswered questions about this virus. That includes exactly how it spreads, how deadly it is, whether it’s commonly transmitted by patients who are not yet displaying symptoms, and other issues.”

According to Alex Azar, secretary of Health and Human Services, and chair of President Trump’s Coronavirus Task Force, there are 12 confirmed cases of the novel coronavirus in the United States, including two cases of transmission to people who had not recently been in China. “Although the virus represents a potentially very serious public health threat, and we expect to continue seeing more cases here, the immediate risk to the American public is low at this time,” Mr. Azar said. “We are working as quickly as possible on the many unanswered questions about this virus. That includes exactly how it spreads, how deadly it is, whether it’s commonly transmitted by patients who are not yet displaying symptoms, and other issues.”

 

A randomized, controlled trial of Gilead’s antiviral drug remdesivir is currently underway in China in hopes that it will be an effective treatment for the 2019 Novel Coronavirus (2019-nCoV).



“What they’re looking at is the effect of this drug -- either the drug plus standard of care versus standard of care alone,” Anthony S. Fauci, MD, reported Feb. 7 during a press briefing held by members of President Trump’s Coronavirus Task Force. “I think pretty soon we are going to get a definitive answer, whether one of these among several drugs works.”

Dr. Fauci, director of the National Institute of Allergy and Infectious Diseases, added that several organizations and individual investigators are developing vaccines for 2019-nCoV. In one such effort, the National Institutes of Health is working with Moderna Inc. to develop a vaccine built on a messenger RNA platform. “One of the first steps is to successfully get that [novel coronavirus] gene and insert it into the messenger RNA platform successfully and allow it to express proteins,” Dr. Fauci explained. “We’ve succeeded in that. The next [step] is to put it in a mouse animal model to induce immunogenicity, and to get the company to make [gold nanoparticle] products. All of those have been successfully implemented. There have been no glitches so far. If that continues, we will be in Phase 1 trials in people within the next two-and-a-half months.”

CDC begins coronavirus diagnostic test kit distribution; new case confirmed in Wisconsin

Article Type
Changed

The Centers for Disease Control and Prevention and the Wisconsin Department of Health Services confirmed a new case of the 2019 Novel Coronavirus (2019-nCoV) on Feb. 5, 2020, bringing the total number of cases in the United States to 12.* 

Earlier in the day, Nancy Messonnier, MD, director of the CDC National Center for Immunization and Respiratory Diseases, told reporters that 206 individuals under investigation had tested negative for infection with the novel virus and that tests were pending on another 76 individuals.

The agency also announced during a press briefing call that diagnostic test kits will begin shipping on Feb. 5, less than 24 hours after receiving an emergency use authorization from the Food and Drug Administration. Full information is available in an article published in the Morbidity and Mortality Weekly Report.

The emergency use authorization will allow for broader use of the CDC’s 2019-nCoV Real Time RT-PCR Diagnostic Panel, which to date has been limited for use at CDC laboratories. Under the emergency use authorization, the diagnostic kit is authorized for patients who meed the CDC criteria for 2019-nCoV testing. The diagnostic test is a reverse transcriptase polymerase chain reaction test that provides presumptive detection of 2019-nCoV from respiratory secretions, such as nasal or oral swabs. A positive test indicates likely infection, although a negative test does not preclude infection and should not be the sole determination for patient management decisions.

“Today, the test kits will start shipping to over 100 U.S. public health labs,” she said. “Each of these labs is required to perform international verification for [Clinical Laboratory Improvement Amendments] compliance prior to reporting out. This process is expected to take a few days.”

Dr. Messonnier said that 200 test kits will be distributed to domestic labs and another 200 test kits will go to select international labs. Each kit can perform diagnostics on 700-800 patient samples.

“What that means is that, by the start of next week, we expect there to be much enhanced capacity for laboratory testing closer to our patients,” she said, adding that additional test kits are being produced and will be available for ordering in the future. Each laboratory that places an order will receive one test kit.

“Distribution of these tests will improve the global capacity to detect and respond to this new virus,” Dr. Messonnier said. “Availability of this test is a starting place for greater commercial availability of diagnostic testing for nCoV.”

The CDC also said that the next batch of passengers arriving from Wuhan, China, will be arriving in one of four locations: Travis Air Force Base, Fairfield, Calif.; Marine Corps Air Station Miramar, San Diego; Lackland Air Force Base, San Antonio; and Eppley Airfield, Omaha, Neb. Passengers will be quarantined for up to 14 days from the day the flight left Wuhan and medical care will be provided if needed.

“We do not believe these people pose a threat to the communities where they are being housed as we are taking measures to minimize any contact,” she said, adding that confirmed infections are expected among these and other returning travelers.

Dr. Messonnier warned that the quarantine measures “may not catch every single returning traveler returning with novel coronavirus, given the nature of this virus and how it is spreading. But if we can catch the majority of them, that will slow the entry of this virus into the United States.”
