DENVER – , according to research presented at the annual meeting of the Consortium of Multiple Sclerosis Centers. “Herpes zoster and its complications are associated with increased health care cost and decreased quality of life,” lead author Nikita Stempniewicz, MSc, director of U.S. Health Outcomes & Epidemiology at GSK Vaccines, Alexandria, Va., reported.
“The take-home finding is that herpes zoster incidence is high among people with MS overall,” Mr. Stempniewicz said in an interview. “We also found that herpes zoster incidence is numerically higher among MS patients with higher levels of baseline immunosuppression, so another conclusion is that herpes zoster prevention may be warranted among this population given the high level of immunosuppression and the high risk of developing herpes zoster infection.” GSK manufactures Shingrix, the only currently approved and recommended herpes zoster vaccine available in the United States
Lawrence Steinman, MD, a professor of neurology and neurological sciences, pediatrics, and genetics at Stanford (Calif.) Medicine, was not involved in the research but said in an interview that the findings “raise the issue of whether not enough individuals with MS are getting Shingrix, and also whether there is a need for rapid intervention with an antiviral, for those individuals who develop shingles.”
Real-world data
For the study, researchers analyzed U.S. administrative claims data from the Optum Research Database between October 2015 and March 2022 to compare shingles infections between adults with MS (and no other immunocompromising conditions) and a random sample of one million people without any immunocompromising conditions. The study excluded anyone who had been vaccinated against herpes zoster or diagnosed with it in the year before October 2015.
Among the 42,185 adults with MS included in the cohort, just over half (53%) were commercially insured, and 47% had Medicare Advantage. Their average age was 53, and 75% were female. Just over half the cohort (55%) had no immunosuppression because of medications while 35% had low immunosuppression from MS therapy and 10% had high immunosuppression from therapy. High suppression meant patients were taking fingolimod, siponimod, ozanimod, ponesimod, cladribine, or a monoclonal antibody except natalizumab. Those with low suppression were taking natalizumab, fumarates, IVIG, glatiramer acetate, interferon beta or a related drug, teriflunomide, azathioprine, methotrexate, or mycophenolate mofetil.
The rate of shingles infections in the MS patient population was 13.8 per 1,000 people per year, compared with 5.6 infections per 1,000 immunocompetent people per year (adjusted incident rate ratio, 1.69; 95% confidenceinterval, 1.58-1.81. When broken down by age, younger adults aged 18-49 with MS were more than three times more likely to develop shingles (incidence rate, 11.6 per 1,000 people per year) than immunocompetent younger adults (IR, 3.5). The gap was narrower for those age 50 and older, where adults with MS had a rate of 15.2 infections per 1,000 people per year versus 8.6 per 1,000 immunocompetent people per year.
Although MS patients with a higher baseline level of immunosuppression from therapy had higher herpes zoster infection rates (18 cases per 1,000 people per year) than those with low immunosuppression (14 cases per 1,000 people per year) or no immunosuppression from medication (13 cases per 1,000 people per year), rates for all three remained higher than for the immunocompetent population.
Herpes and MS: Some questions still unanswered
“We’ve known that herpes zoster is more common in people with MS, and we’ve known that it is seen in people on MS therapies,” Robert Fox, MD, a staff neurologist at the Mellen Center for MS and vice-chair for research at the Neurological Institute at the Cleveland Clinic, said in an interview. “What we haven’t known is just how much more common it is in people with MS than the rest of the adult population and whether it truly is more common in people taking MS therapies than people not taking MS therapies. This study puts real, population-based numbers on the incidence rates.”
Dr. Fox, who was not involved in the research, noted that a limitation of the study was the inability to know the risk of shingles according to specific MS therapies since all the therapies were grouped together.
”So I can’t say to a patient that their particular therapy increases their risk,” Dr. Fox said. “Similarly with the MS therapies listed in the ‘high’ immunosuppression category: We don’t know that each of the therapies listed do in fact increase the rate of herpes zoster. We just know that the group of MS therapies bunched into the ‘high’ category, on the whole, increase the rate of herpes zoster.”
The study does not provide any information about the impact of Shingrix vaccination, he added, since vaccinated individuals were excluded from the analysis.
Timing the vaccination with MS therapy
Dr. Steinman said in an interview that he recommends herpes zoster vaccination to his patients with MS.
“The mistake that people make with MS is that they don’t want to take the [herpes zoster] vaccine, and they should be taking it,”
Dr. Steinman said. “In a perfect world, they would get it before they went on their [immunosuppressive] drug. But now we’ll have a lot of people who didn’t take the vaccine; they can get it while they’re on their drug.” Although it depends on the particular therapy they’re taking, Dr. Steinman said that most people can get the shingles vaccine while continuing their medication.
The Centers for Disease Control and Prevention recommends that adults who are or will be immunodeficient or immunosuppressed because of a disease or therapy get two doses of the Shingrix vaccine against herpes zoster, regardless of whether they have previously been vaccinated with Zostavax or have ever had shingles. The agency has also issued detailed clinical guidance regarding how to administer the vaccine to individuals taking immunosuppressive therapy, including the option to administer the second dose 1-2 months after the first instead of 2-6 months to “facilitate avoiding vaccination during periods of more intense immunosuppression,” the agency wrote.
The research was sponsored, funded, and analyzed by GSK, which manufactures the shingles vaccine Shingrix, and Mr. Stempniewicz is a GSK employee. Two other authors are GSK employees, and three authors are employees of Optum who received fees from GSK for this study. Dr. Steinman and Dr. Fox reported no relevant disclosures.
