ORLANDO – The eruption spread away from the head and her transaminase levels were “dramatic,” in the 700s, said Kalyani S. Marathe, MD, MPH, associate professor of dermatology and pediatrics at the University of Cincinnati.
Dr. Marathe, director of the division of dermatology at Cincinnati Children’s Hospital, reviewed this case in a presentation on pediatric dermatologic emergencies at the ODAC Dermatology, Aesthetic & Surgery Conference, pointing out potential pitfalls and important aspects that might require swift action.
The patient was diagnosed with drug reaction with eosinophilia and systemic symptoms (DRESS).
Facial involvement is common in pediatric cases of DRESS, but edema of the face is less common in children than adults, Dr. Marathe said.
Antiepileptic medications are the most common cause of DRESS, followed by antibiotics – most often, vancomycin and trimethoprim/sulfamethoxazole, she said. But sometimes the trigger is not clear, she noted, recalling a vexing case she once saw in which IV contrast was eventually identified as the cause.
When DRESS is suspected, she said, lab work should be done during the acute eruption and after resolution. This should include CBC, liver function tests, creatinine, and urinalysis, and human herpesvirus 6 (HHV-6) and thyroid testing.
Treatment typically includes supportive care, unless symptoms are systemic, or if there is impending liver failure, when steroids, cyclosporine, or IVIG can be used.
Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN): Mortality rates when these diseases overlap is 4%, Dr. Marathe said. Clues to diagnosing this other medication-induced condition include involvement of the palms and the soles of the feet; presence of the Nikolsky sign in which the top layers of the skin slip away from the lower layers when rubbed; mucosal involvement, which often precedes cutaneous involvement; and these symptoms occurring within the first 8 weeks of taking a medication, which are most commonly antibiotics and anti-epileptics.
Dr. Marathe underscored how important it is to get ophthalmology involved right away, because of the risk of vision loss. Amniotic membrane transfer to the eye at the time of diagnosis has been found to produce dramatically better outcomes, she said. The membrane has anti-inflammatory and antiscarring properties and can promote wound healing on the surface of the eye.
“I would recommend getting your ophthalmology team on board early because they have to advocate for these patients,” she said.
Corticosteroids and IVIG can improve ocular outcomes, but cyclosporine is associated with better mortality outcomes, she said. Emerging data on etanercept has also led to more use of that drug, she said.
Erythema multiforme (EM): unlike urticaria, multiforme EM can have mucosal involvement, Dr. Marathe said. Clinicians should look for three zones of color: A central duskiness, a rim of pallor, and a ring of erythema.
EM is triggered by a virus, which is usually herpes simplex virus (HSV). But she added that HSV is not always found. “So, there are certainly other triggers out there that we just haven’t identified,” she said.
If HSV is suspected, oral acyclovir is effective, she noted.
Other cases might not be as straightforward. Dr. Marathe said that during her fellowship, she saw a patient with EM that was controlled only by IVIG, so it was administered every 3 months. In that case, the trigger was never found.
Multisystem inflammatory syndrome in children (MIS-C): This syndrome can follow COVID-19 infection, and usually presents with 3-5 days of fever after COVID has resolved. It can include gastrointestinal, cardiorespiratory, and neurocognitive symptoms.
The skin presentation is mainly a morbilliform pattern, but clinicians might also see conjunctival involvement, mucosal involvement, and “COVID toes,” painful red or purple lesions on the toes.
Treatment is usually IVIG and systemic corticosteroids, with the treatment course depending on the severity.
MIS-C was initially thought to be Kawasaki’s disease, another autoinflammatory disorder, which is related but distinct, Dr. Marathe said.
Patients with MIS-C “are usually going to have COVID-positive antibodies,” she said. But since almost everybody may have COVID antibodies, “it’s not usually a helpful test for you now. But early on, that’s what we used as helpful indicator.”
Dr. Marathe reported no relevant financial relationships.
