Celltrion Group (Incheon, Korea) has launched two rapid COVID-19 testing kits, SAMPINUTE COVID-19 Antigen MIA for detection of SARS-CoV-2 antigen, and DiaTrust COVID-19 IgG/IgM Rapid Test for detection of SARS-CoV-2 IgG/IgM antibody in the US.

SAMPINUTE COVID-19 Antigen MIA is an electrochemical immunoassay test for detection of SARS-CoV-2 antigen from nasopharyngeal swab samples, composed of one time use test cartridges and a portable analyzer. DiaTrust COVID-19 IgG/IgM Rapid Test is a one-step in-vitro diagnostic test based on immunochromatographic assay designed for the rapid detection of antibodies of the novel coronavirus in healthcare settings. Both the rapid tests kits have shown a reliable performance and promising clinical trial results. SAMPINUTE COVID-19 Antigen MIA has a sensitivity of 94% and a specificity of 100%, with time to results within 10 minutes. DiaTrust COVID-19 IgG/IgM Rapid Test has also shown a reliable performance with 96% positive percent agreement and 98.67% negative percent agreement for IgM, 92% positive percent agreement and 100% negative percent agreement for IgG. The test has a turnaround time of 15 minutes.

“Celltrion has been striving to bring the tests into the US. The need for more accessible, affordable, and most importantly, rapid diagnostic testing will grow, as the daily activities are coming back, and the economy is opening up again,” a Celltrion representative stated. “With the short turnaround time and promising performance of the sensitivity and specificity results, Celltrion is confident that both SAMPINUTE COVID-19 Antigen MIA and DiaTrust COVID-19 IgG/IgM Rapid Test will add great value to healthcare providers in screening patients and keeping communities safe.”

Prospective randomized trial of interventions for vincristine-related neuropathic pain

Doralina L Anghelescu, Jessica Michala Tesney et al.
Pediatr Blood Cancer. 2020 Jul 2 e28539 [Epub ahead of print]
BACKGROUND To evaluate the efficacy of gabapentin at 20 mg/kg per day in the treatment of vincristine-related neuropathic pain.

PROCEDURE Children aged 1-18 years who developed vincristine-induced neuropathy on a St Jude frontline acute lymphoblastic leukemia trial were prospectively enrolled on a randomized, double-blind, placebo-controlled, phase II trial with two treatment arms: gabapentin plus opioid versus placebo plus opioid. Daily evaluations of morphine dose (mg/kg per day) and pain scores were conducted for up to 21 days; the values of the two arms were compared to assess analgesic efficacy.

RESULTS Of 51 study participants, 49 were eligible for analyses. Twenty-five participants were treated with gabapentin, with a mean (SD) dose of 17.97 (2.76) mg/kg per day (median 18.26, range 6.82-21.37). The mean (SD) opioid doses taken, expressed as morphine equivalent daily (mg/kg per day), were 0.26 (0.43) in the gabapentin group (25 patients, 432 days) and 0.15 (0.22) in the placebo group (24 patients, 411 days; P = .15). Only the risk classification of acute lymphoblastic leukemia was significantly associated with the daily morphine dosage (P = .0178): patients in the lower risk arm received higher daily morphine dosages. Multivariate analyses revealed a significant difference between the groups' average daily scores for the previous 24 h and'right now.'

CONCLUSION In this population of children with vincristine-related neuropathic pain, opioid consumption and pain scores were higher in the gabapentin group than in the placebo group. Future randomized, double-blind, placebo-controlled studies should test gabapentin given longer or at a higher dose.

FDA approves generic albuterol inhaler to mitigate shortages during pandemic

 | Post date: 2020/07/8 | 
On April 8, FDA, recognizing the increased demand for albuterol products during the novel coronavirus pandemic, approved the first generic albuterol inhaler. The albuterol sulfate metered-dose inhaler, 90 mcg/inhalation (Cipla Ltd) is the first AB-rated generic therapeutic equivalent version of Merck’s Proventil HFA and the first generic metered-dose inhaler to be approved in almost 2 decades. The generic inhaler is used to treat or prevent bronchospasm in patients ages 4 years and older who have reversible obstructive airway disease and to prevent exercise-induced bronchospasm in this age group.

Addressing shortages

According to the American College of Allergy, Asthma, and Immunology (ACAAI), certain areas of the country are experiencing shortages of albuterol inhalers because of their increased use in hospitals for patients with COVID-19. These shortages could have implications for the more than 26 million people in the United States who have asthma, of which 7 million are children.

“FDA recognizes the increased demand for albuterol products during the novel coronavirus pandemic,” said FDA Commissioner Stephen M. Hahn, MD. “We remain deeply committed to facilitating access to medical products to help address critical needs of the American public.”
According to allergist Michael Blaiss, MD, ACAAI executive medical director, the organization learned of possible shortages about a month ago. “With the introduction of this inhaler, we have a generic product to add to the supply,” Blaiss said in a statement to patients on ACAAI’s website. “While shortages may not be occurring in every part of the country, we want patients to know they may now have additional options if they are having an issue getting their medicine.”
ACAAI has developed recommendations for patients with asthma who are having difficulties accessing inhalers (see sidebar).

Dosage and administration

The recommended dosage for adults and children ages 4 years and older is two inhalations repeated every 4 to 6 hours. More frequent administration or a larger number of inhalations is not recommended. In some patients, one inhalation every 4 hours may be sufficient.
Each actuation delivers 108 mcg of albuterol sulfate (equivalent to 90 mcg of albuterol base) from the mouthpiece.
Patients should prime the inhaler before using for the first time and in cases where the inhaler has not been used for more than 2 weeks by releasing four test sprays into the air, away from the face.

What do we know for sure about hydroxychloroquine for COVID-19? Not much

 | Post date: 2020/07/8 | 
For a while there, hydroxychloroquine (HCQ) became the new toilet paper: Everyone thought they needed it to stay safe during COVID-19, and resulting demand placed stress on supply.
HCQ had support from high places. President Trump called it “a game changer” at a White House press briefing on March 19. “What do you have to lose? Take it. I really think they should take it,” he said at another briefing on April 4. But in late April, FDA cautioned against its use for COVID-19 outside of a hospital setting. By June 15, FDA had put the kibosh on the whole thing—it revoked the drug’s emergency use authorization (EUA).

How did we get here?

Promise

Researchers had been exploring the use of antimalarials like HCQ and chloroquine (CQ) against viral infections for decades, so the recommendation wasn’t totally implausible. CQ had shown promise against the 2002 outbreak of sudden acute respiratory syndrome (SARS), another coronavirus, by inhibiting viral replication.
In addition, some hypothesized that CQ or HCQ could inhibit immune response that could lead to lung and other organ damage in patients with COVID-19.
Trump’s initial endorsements came from two sources. A letter in BioScience Trends summarized the experience of a Chinese medical group, reporting that “results from more than 100 patients have demonstrated that chloroquine phosphate is superior to the control treatment in inhibiting the exacerbation of pneumonia, improving lung imaging findings, promoting a virus negative conversion, and shortening the disease course.” The letter, however, included no additional detail about study design, patient selection criteria, outcomes, or safety. Read the letter at https://apha.us/BioSciTrends.
An International Journal of Antimicrobial Agents study out of France included more detail but still had significant limitations. Read that study at https://apha.us/HCQFrance.
The French study had a very small sample size—42 patients were enrolled, of whom 16 were controls. Still, it found that patients who were positive for COVID-19 and were treated with HCQ, sometimes in combination with azithromycin depending on a patient’s clinical presentation, had a significantly reduced viral load compared with controls.
HCQ hype was born. Though evidence supporting their effectiveness was scant, FDA approved HCQ and CQ for COVID-19 treatment by EUA on March 28. EUA was granted based on SARS-CoV-2’s potential to cause life-threatening disease; a reasonable belief that HCQ/CQ could effectively treat COVID-19 based on the limited in vitro and anecdotal clinical data in case series, and that the drugs’ known and potential benefits outweighed their known and potential risks; and the lack of an adequate, approved, and available alternative treatment.
Literature about HCQ and COVID-19 began to proliferate, but most consisted entirely of speculation (https://apha.us/Speculation), hypothesis (https://apha.us/Hypothesis), calls for further study (https://apha.us/FurtherStudy), or trial design proposals (https://apha.us/Proposal).

COVID-19: Bacteriophage Could Decrease Mortality

 | Post date: 2020/06/29 | 

New Rochelle, NY, June 24, 2020—Bacteriophage can reduce bacterial growth in the lungs, limiting fluid build-up. This could decrease the mortality of patients affected by COVID-19, according to the peer-reviewed journal PHAGE: Therapy, Applications, and Research. Click here to read the article.

“The bacterial growth rate could potentially be reduced by the aerosol application of natural bacteriophages. These prey on the main species of bacteria known to cause respiratory failure,” says Marcin Wojewodzic, PhD, University of Birmingham (U.K.).

Decreasing bacterial growth would also give the body more time to produce protective antibodies against the disease-causing coronavirus.

“Used correctly, phages have an advantage here of being able to very specifically target the bacteria that cause secondary infections,” said Martha Clokie, PhD, Editor-in-Chief of PHAGE and Professor of Microbiology, University of Leicester (U.K.). “They would remove the problematic bacterium but leave an otherwise fragile microbiome intact.”

Social isolation can lead to depression in children long after current lockdown

 | Post date: 2020/06/28 | 

Children and adolescents are likely to experience high rates of depression and anxiety long after current lockdown and social isolation ends and clinical services need to be prepared for a future spike in demand, according to the authors of a new rapid review into the long-term mental health effects of lockdown.

The research, which draws on over 60 pre-existing, peer-reviewed studies into topics spanning isolation, loneliness and mental health for young people aged 4 – 21, is published today (Monday 1 June 2020) in the Journal of the American Academy of Child and Adolescent Psychiatry.

According to the review, young people who are lonely might be as much as three times more likely to develop depression in the future, and that the impact of loneliness on mental health could last for at least 9 years.

The studies highlight an association between loneliness and an increased risk of mental health problems for young people. There is also evidence that duration of loneliness may be more important than the intensity of loneliness in increasing the risk of future depression among young people.

This, say the authors, should act as a warning to policymakers of the expected rise in demand for mental health services from young people and young adults in the years to come – both here in the UK and around the world.

Is COVID-19 Risk Linked to Blood Type?

One of the things that has really bothered me about COVID-19 is the dramatic variability in presentation, from being asymptomatic to having sniffles, complete respiratory failure requiring ECMO, and, of course, death. I've seen all of these firsthand at this point. And sure, we know that there are risk factors for bad outcomes, such as older age and comorbidities. But ask any of us who have cared for these patients and we'll tell you that there is clearly other stuff going on. I've seen a 35-year-old man with no comorbidities fighting for his life on ECMO.

It seems logical that genetics may play a role here, but those studies are just in the early phases. Nevertheless, some tantalizing clues are emerging—and some from really unlikely places.

Okay. A couple of months ago, my family did tests to figure out our blood type. We did this for no scientific or medical reason; we were bored, stuck at home, wanted some fun science-y stuff to do with the kids, and found some cheap kits on Amazon.

I am type O. My wife, type A.

And that was that. Until I started seeing that blood type may be associated with the risk for coronavirus infection and death from COVID-19.

This supposition immediately raised red flags for me. Correlating blood type with various outcomes has long straddled the border between regular science and pseudoscience—and often had a racially tinged flavor. I am pretty sure blood type does not correlate with various personality traits, for example. So why would blood type dictate susceptibility to a respiratory virus?

But, since I am often wrong and love to find out when I'm wrong, I looked into it. And I honestly think there may be something here.

Caveats: Data are really limited, and studies are sort of trickling out in preprint form and in various esoteric journals. But I'll point out a couple that hold water for me.

The first, a preprint out of China, looked at just over 2000 COVID-positive individuals and reported that there was a higher infection rate in people with type A blood.

What you see here is that there was a higher-than-expected rate of individuals with blood group A diagnosed with COVID-19 than in the general population.


 

Conversely, fewer-than-expected individuals with blood group O appeared in the pool of those infected. Similar results were seen when the analysis was restricted to the 206 individuals who died from COVID-19. Again, blood group A was overrepresented.
