“There have also been recent reports of VZV antigen/DNA found in the vessel wall of patients with giant cell arteritis and granulomatous arteritis of the aorta,” she said. “This is an evolving story about zoster that we never knew about.”
Drug-induced hypersensitivity syndrome (DIHS) is also associated with CNS manifestations, but they resolve much faster, unlike those of CNS zoster. “As long as you take away the offending medication and put them on steroids they will recover very quickly,” she said. At least one case in the medical literature to date has reported DIHS in association with VZV (Acta Derm Venereol. 2015;95[4]:503-4).
The zoster vaccine (Zostavax, Merck & Co.) is currently indicated in patients aged 60 years and older, but since it is a live attenuated vaccine, it is contraindicated in many patients who could most benefit from it, including those with primary immunodeficiency disorders, those with a hematologic malignancy, those who have had a hematopoietic stem cell transplant within the last 2 years, pregnant patients, and patients taking high-dose steroids or anti–tumor necrosis factor biologics.
“There is an inactivated vaccine in the works being tested, and that is showing good efficacy,” Dr. Ahronowitz said. “Hopefully we’ll be able to prevaccinate patients, even young patients, prior to immune suppression.”
She reported having no relevant disclosures.
