VIENNA — Pneumococcal vaccination administered 1 month prior to starting methotrexate (MTX) in patients with rheumatoid arthritis (RA) allows a significantly higher immunological response at 1 month and does not affect disease control at 1 year, compared with starting MTX simultaneously with the vaccination, according to data from a randomized trial presented at the annual European Congress of Rheumatology.
“Our patients are more susceptible to infection due to immunosuppressive therapy, and it’s recommended they receive vaccination against pneumococcal infection,” the lead author Jacques Morel, MD, PhD, said in his presentation of results from the VACIMRA study.
Timing the vaccination against pneumococcal disease when initiating MTX in clinical practice has been a point of uncertainty, noted Dr. Morel, a rheumatologist from Centre Hospitalier Universitaire, Montpellier, France.
“How can we deal with this in clinical practice where one recommendation is to vaccine before initiation of methotrexate, but it is also recommended to start methotrexate as soon as the diagnosis of RA is made?” he asked.
Comparing Humoral Response of MTX Started Immediately or 1 Month Post-Vaccination
The prospective, randomized, multicenter trial aimed to compare the rate of humoral immunological response against pneumococcal 13-valent conjugate vaccine (PCV13) in patients with RA who had a Disease Activity Score in 28 joints (DAS28) > 3.2, never taken MTX, and never been vaccinated against pneumococcus. Patients were vaccinated either 1 month before MTX initiation (n = 126) or simultaneously with MTX (n = 123). Oral glucocorticoids were allowed but only at < 10 mg/d. Following PCV13 vaccination, all patients also received the 23-valent pneumococcal polysaccharide vaccine (PPV23) 2 months later.
Concentrations of immunoglobulin (Ig) G antibodies against the 13 serotypes contained within PCV13 were measured using enzyme-linked immunosorbent assay (ELISA) and opsonophagocytic killing assay (OPA) at baseline and during follow-up at 1, 3, 6, and 12 months.
Positive antibody response was defined as a twofold or more increase in the IgG concentration using ELISA. The main outcome was the responder rates at 1 month after PCV13, defined by at least three positive antibody responses out of five of the target PVC13 serotypes (1, 3, 5, 7F, and 19A) using ELISA or OPA. Secondary outcomes included comparisons of the percentage of patients responding to each of the 13 vaccine serotypes at 1 month and after the boost with PPV23 and at 3, 6, and 12 months after vaccination with PCV13. The researchers also measured disease activity, infections, and side effects throughout the study.
Dr. Morel highlighted that all the patients had very early RA of less than 6 months, and that their characteristics at baseline were similar in both groups with 70% women, mean age 55.6 years, RA duration 2 months, 69% positive for anticitrullinated protein antibodies, 21% with erosive disease, and a DAS28 based on C-reactive protein of 4.6.
Response rates in those receiving MTX 1 month after vaccination were significantly higher at 88% with ELISA than those at 75% for immediate vaccination (P < .01) and 96% vs 88% with OPA (P = .02). These responder proportions persisted at the 12-month follow-up measurements, remaining higher in the delayed MTX group for both assays and across the 13 serotypes.
Showing a graph of the antibody responses, Dr. Morel explained that “at 12 months, the curves start to converge, but the difference in antibody titers were still significant for eight of the 13 serotypes.”
Disease Activity Not Adversely Affected by Starting MTX 1 Month Later
Regarding medication doses at 12 months, the cumulative glucocorticoid doses were similar between groups during the follow-up. As expected, the 1-year cumulative dose of MTX was higher in those given the drug immediately after vaccination vs delayed (826 vs 734 mg), but the weekly mean doses of MTX were similar at 3, 6, and 12 months between the two groups, and likewise, the use of targeted disease-modifying antirheumatic drugs (DMARDs) at 1 year was comparable. The cumulative glucocorticoid dose at 12 months was similar at 1716 mg with delayed MTX and 1613 mg with immediate MTX.
Not unexpectedly, at 1 month, DAS28 scores were higher with delayed vs immediate MTX at 3.95 vs 3.38 for DAS28-ESR and 3.54 vs 3.01 for DAS28-CRP (P < .01), but after the first month, DAS28 scores were similar between the two groups.
No significant differences were found between the groups for adverse event rates within 7 days of receiving PCV13, with local and systemic reactions occurring at 60%-61% and 50%-58%, respectively; fever at 0%-4%; and severe infections at 12%.
Finally, no difference was found in terms of serious adverse events between groups, with one pneumococcal infection with delayed MTX during follow-up, and there were no unexpected side effects observed with the PCV13 and PPV23 vaccinations.
Rheumatologists’ Reactions
Ernest Choy, MD, head of rheumatology and translational research at the Institute of Infection and Immunity, Cardiff University School of Medicine, Cardiff, Wales, asked if any individual showed no humoral response at all rather than a reduced response. “I ask because if there is no humoral response, then they are at very high risk, and there will be clinical relevance to that.”
Dr. Morel replied that “one serotype showed no response, at least according to the assays used, but we don’t know why. We analyzed at the population [level], not at the individual level, so it is difficult to answer the question.”
Another delegate asked what the participants thought about delaying MTX by 1 month. “When we tell the patient we need to vaccinate before we can use methotrexate [because] otherwise, we will reduce the response to the vaccination, then patient accepts it,” said Dr. Morel, adding that, “we allowed a minimal dose of steroids, and we saw from the results that the DAS28 at 1 month had changed.”
Co-moderator Katerina Chatzidionysiou, MD, PhD, a consultant rheumatologist and head of the Clinical Trial Department Rheumatology Unit, Karolinska University Hospital, Stockholm, Sweden, said that “As a physician, I’d feel uncomfortable delaying MTX if they had very active disease even for a short period of time.”
Dr. Morel replied that, “Today, we have so many drugs that can control the disease, for example, the targeted DMARDs. Progression does not show much variation, and we know x-ray progression with today’s drugs is a lot less than previously.”
Dr. Morel reported financial relationships with AbbVie, Amgen, Biogen, Bristol Myers Squibb, Fresenius Kabi, Galapagos, GlaxoSmithKline, Lilly, Medac, Nordic Pharma, Novartis, Pfizer, Sandoz, Sanofi, Boehringer Ingelheim, and Servier. Dr. Choy had no relevant financial relationships of relevance to this study.

We analyzed at the population [level], not at the individual level, so it is difficult to answer the question.”<br/><br/>Another delegate asked what the participants thought about delaying MTX by 1 month. “When we tell the patient we need to vaccinate before we can use methotrexate [because] otherwise, we will reduce the response to the vaccination, then patient accepts it,” said Dr. Morel, adding that, “we allowed a minimal dose of steroids, and we saw from the results that the DAS28 at 1 month had changed.”<br/><br/>Co-moderator Katerina Chatzidionysiou, MD, PhD, a consultant rheumatologist and head of the Clinical Trial Department Rheumatology Unit, Karolinska University Hospital, Stockholm, Sweden, said that “As a physician, I’d feel uncomfortable delaying MTX if they had very active disease even for a short period of time.”<br/><br/>Dr. Morel replied that, “Today, we have so many drugs that can control the disease, for example, the targeted DMARDs. Progression does not show much variation, and we know x-ray progression with today’s drugs is a lot less than previously.”<br/><br/>Dr. Morel reported financial relationships with AbbVie, Amgen, Biogen, Bristol Myers Squibb, Fresenius Kabi, Galapagos, GlaxoSmithKline, Lilly, Medac, Nordic Pharma, Novartis, Pfizer, Sandoz, Sanofi, Boehringer Ingelheim, and Servier. Dr. Choy had no relevant financial relationships of relevance to this study.<span class="end"/></p> <p> <em>A version of this article appeared on <span class="Hyperlink"><a href="https://www.medscape.com/viewarticle/no-detriment-ra-starting-mtx-month-after-pcv13-2024a1000b6z">Medscape.com</a></span>.</em> </p> </itemContent> </newsItem> <newsItem> <itemMeta> <itemRole>teaser</itemRole> <itemClass>text</itemClass> <title/> <deck/> </itemMeta> <itemContent> </itemContent> </newsItem> </itemSet></root>
