Is COVID-19 an Indication to Temporarily Modify Dermatological Management Plans?

While the world lives under the shadow of the novel coronavirus (COVID-19) pandemic, dermatologists wonder if the current situation calls for a temporary change in the management of skin conditions.

Immunosuppressive drugs are used ubiquitously in the modern treatment of inflammatory and autoimmune skin diseases like psoriasis, bullous diseases, connective tissue diseases, and many others. Treatment of these conditions is based on the suppression of the patient’s immune system using steroids, steroid-sparing drugs, and biological agents.1

While the effects of the novel coronavirus on the body and its immune system are still being studied, there is overwhelming evidence that the virus could directly or indirectly affect the immune system. In one study, lymphocytopenia was reported in 83.2% of the admitted patients and might be associated with a worse prognosis.2In another study, a steady decline in the lymphocyte counts was recorded in a group of patients who did not survive the infection.3

While the coexisting comorbid medical conditions (such as diabetes or heart disease) are considered as independent predictors of an adverse outcome of the novel coronavirus infection,4 it could be assumed that the chronic inflammatory and autoimmune skin diseases like psoriasis by themselves might imply an additional risk factor of developing more serious symptoms of the novel virus due to their chronicity and effects on the immune system.5

The use of immunosuppressive to treat these conditions can amplify this effect, and it might leave the patient vulnerable to more serious complications should an infection with the novel coronavirus be established. Hence, it may be wise to restrict temporarily the use of immunosuppressive agents including systemic steroids, steroid-sparing agents, and biologics in dermatology daily practice until more evidence is available about their safety in the current pandemic.6As a relates point, the International Psoriasis Council declared an urgent statement on March 11, 2020 that the physician should be alert to the potentially harmful effects of COVID-19 infection on patients with psoriasis and to immediately discontinue or postpone immunosuppressant medications for psoriasis patients diagnosed with COVID-19 disease.7

The following is an excerpt from Dermatology News Expert Analysis, Conference Coverage from ODAC.  

ORLANDO – Because Food and Drug Administration–approved treatment options for children and adolescents with severe dermatologic diseases are limited, systemic therapies for these patients often require the use of off-label medications. However, this scenario is changing, A. Yasmine Kirkorian, MD, said at the ODAC Dermatology, Aesthetic & Surgical Conference.

“I really would like to emphasize that children with severe disease need to be treated,” added Dr. Kirkorian, a pediatric dermatologist at George Washington University, Washington, and Children’s National Health System, where she is interim chief of the division of dermatology.

Current on-label systemic therapies for pediatric skin disease include etanercept for psoriasis (4 years and older), ustekinumab for psoriasis (12 years and older), adalimumab for hidradenitis suppurativa (12 years and older), and omalizumab for chronic idiopathic urticaria (12 years and older). A new addition to the list is dupilumab, which was approved for children and adolescents with atopic dermatitis (AD) aged 12 years and older in 2019, she noted.

CBD Oil for Psoriasis

Health recently wrote an article asking if CBD oil can relieve psoriasis symptoms.

In recognition of Psoriasis Awareness Month, I consulted Adam Friedman, MD, FAAD, professor and interim chair of dermatology at the George Washington School of Medicine and Health Sciences. Dr. Friedman is also the residency program director, director of translational research and director of the Supportive Oncodermatology Clinic. In addition, Dr. Friedman serves as Medical Director for ODAC -Dermatology, Aesthetic & Surgical Conference.

Can CBD help relieve psoriasis symptoms? 

We have only begun to scratch the surface of the unbridled potential of cannabinoids as therapeutic agents. Interestingly enough, psoriasis is one of the listed indications for medical cannabis in the great state of Connecticut, though little is really known on this and many other spaces in dermatology.

Let’s take a step back and first talk about CBD. CBD stands for cannabidiol, one of about 120 different molecules that come from the cannabis plant. It’s the second most prevalent active ingredient in cannabis – tetrahydrocannabinol (THC) is the first. But unlike other cannabinoids – such as THC — CBD does not produce a euphoric “high” or psychoactive effect. That said, it has tremendous biological reactivity through binding to a multitude of receptors, including the cannabinoid specific receptor, CB2r, which is expressed by practically every immune cell (as opposed to CB1r, which is most heavily expressed in the peripheral and central nervous system), regulating skin physiology by being anti-inflammatory, lipostatic and antiproliferative.

Now back to the original question. Inflammatory skin conditions such as psoriasis result from a number of aberrant responses of the immune cells and immune signaling in the skin. Looking at psoriasis specifically, dysregulation of the skin immune system results in marked proliferation and keratinization of epidermal cells. Overactivation of Th1 and Th17 inflammatory responses in psoriasis produces cytokines like IL-17 and IL-22 that set off cascades of events resulting in increased keratinocyte proliferation, expression of keratins 6 and 16, and inflammatory cell infiltration. Because of its role in regulating the inflammatory response of keratinocytes and dermal immune cells, the endocannabinoid system offers potential targets for the management of many inflammatoryskin conditions, but the data to date is rather limited, mostly to cell bases, ex vivo and animal models.

This is what we know:Activation of the endocannabinoid system in the skin reduces inflammation through a number of mechanisms, such as shifting the pro-inflammatory Th1 response to an anti-inflammatory Th2 response via CB2r activation (thank you, CBD). The endocannabinoid system also plays a role in regulating keratinocyte proliferation and differentiation, which are pathologically increased in psoriasis. For example, CB1r activation by cannabinoids such as anandamide (AEA) inhibits keratinocyte differentiation and decreases production of keratin K6, a marker of keratinocyte hyperproliferation. The potential therapeutic effects of CBD in psoriasis also include activation of non-cannabinoid receptors such as GPR55, which reduces inflammation caused by nerve growth factor, and PPARα and PPARγ which reduces epidermal hyperplasia via suppressed proliferation of keratinocytes.

Understanding and Using Biosimilars

One of the only things the dermatology community knows about biosimilar use is that there are many unknowns. Still, biosimilars are on dermatologists’ radars as having the potential to lower the high costs of biologic treatments for chronic skin diseases, including psoriasis.

There also are misperceptions—even among dermatologists—about what biosimilars are and if these drugs can be used to treat patients, according to Leon H. Kircik, M.D., clinical associate professor of dermatology at Indiana University School of Medicine, Indianapolis; clinical associate professor of dermatology at Mount Sinai Medical Center, New York City; and medical director of Physicians Skin Care in Louisville, Ky. who presented “Biosimilars: What You Need to Know” at the Orlando Derm Aesthetic and Clinical conference in Miami, Fla., in January 2017.

Misperception number one

The first misperception is that biosimilars are generic biologics. They’re not, he says.

“You cannot have a generic of a biologic because every biologic is made differently. So, it is important for everybody to understand that biosimilars are not generics,” says Dr. Kircik,

As a result, the approval process for biosimilars is different for that of generics. Biosimilars came about because of the Biologics Price Competition and Innovation Act of 2009, which passed in Congress as a provision of the Affordable Care Act. Biosimilars have an abbreviated licensure pathway, but it’s a different pathway compared to a generic.

“Biopharmaceuticals are biopolymers of organic molecules that are manufactured in living systems. Function is based not only on the amino acid number and sequence but also on posttranslational modification (e.g. glycosylation) that are added by virtue of manufacture in living systems.”

Complexities and blurred lines

The FDA’s definition of a biosimilar, according to Dr. Kircik is, “A biological product that is highly similar to the reference product, notwithstanding minor differences in clinically inactive components. There are no clinically meaningful differences from the reference product in terms of the safety, purity, and potency”

“Those are very vague terms,” Dr. Kircik says.

The first biosimilar (not for use in dermatology), Zarxio [Sandoz], was FDA approved in March 2015. Zarxio is biosimilar to Neupogen (Amgen, filgrastim)1

More than a year later, the first biosimilar to have dermatologic indications received FDA approval—a biosimilar of infliximab, by the name of Inflectra (Celltrion). Interestingly, Inflectra, a biosimilar to Janssen Biotech’s Remicade, has an indication for psoriasis but no data on dermatologic disease, including psoriasis, Dr. Kircik says.
