Prevention of Shingles in Dermatology Patients on Systemic Medications.

Abstract

The lifetime risk for herpes zoster (HZ) of approximately 1 in 3 is increased with advancing age, a family history of HZ, diseases with altered immune function, immunosuppression, physical trauma and psychological stress. In dermatology, monotherapy with current biologics does not increase risk, however systemic steroids, Janus kinase inhibitors and combination biologic/conventional disease-modifying antirheumatics do. The recombinant zoster vaccine (RZV, Shingrix®), an adjuvanted non-live subunit vaccine against the glycoprotein E subunit of varicella zoster virus, is approved for prevention of HZ in adults ≥50 years of age, and adults ≥18 years of age who are or will be at increased risk of HZ due to immunodeficiency or immunosuppression due to disease or treatment. It is administered as two 0.5 ml intramuscular injections 2-6 months apart. In immunocompromised individuals, the spacing between injections may be reduced to 1-2 months. Where possible, the first dose should be administered at least 14 days before onset of immunosuppressive treatment. Studies in immunocompetent individuals have shown high efficacy including prevention of HZ, postherpetic neuralgia and other complications, with persistence of effect 10 years after vaccination. The acceptable safety profile and efficacy in five different immunocompromised populations support its use in at-risk adult dermatologic patients.
