medwireNews: COVID-19 vaccination should be actively promoted for women with rheumatic and musculoskeletal diseases (RMDs) who are pregnant or planning a pregnancy, say researchers.

Their findings, presented in a poster at ACR Convergence 2022 in Philadelphia, Pennsylvania, USA, showed a higher rate of preterm birth among 47 unvaccinated or partially vaccinated (one dose) women with RMD who developed COVID-19 during their pregnancy than 26 similar women who were fully vaccinated (two or more doses), at 29.5% versus 18.2%. The between-group difference did not reach statistical significance, however.

The most common RMDs were systemic lupus erythematosus (23%) and rheumatoid arthritis (21.9%), and the majority (70%) of patients were in remission when diagnosed with COVID-19.

At the time of data extraction, there were 55 completed pregnancies, 50 of which were live births. The most frequent neonatal complication was low birthweight (<2500 g), occurring in 24% of live births, and small for gestational age (below the 10th percentile), occurring in 14%.

Most of the women were unvaccinated when diagnosed with COVID-19, while 4% were partially vaccinated and 36% fully vaccinated.

Hospital admission was necessary for 21% of women, regardless of vaccination status, but only 16% needed COVID-19 specific medication.

“This would imply COVID-19 severity was similar between vaccinated and partially vaccinated or unvaccinated women,” said Sinead Maguire (St James’ Hospital, Dublin, Ireland) in a press release. “This was an unexpected result, given the differences in obstetric and neonatal outcomes.”
