Systematic review and meta-analysis of HPV vaccination in women with systemic lupus erythematosus (SLE).

OBJECTIVE

We conducted a systematic review and meta-analysis to access HPV vaccines' safety and immunogenicity in Systemic Lupus Erythematosus (SLE) women.

METHODS

The search was conducted in the most relevant databases. Meta-analyses to evaluate seroconversion rates for each HPV vaccine type and SLE flare rates after vaccination were performed.

RESULTS

We identified 3,467 articles; six papers referring to SLE population were included. Five articles that evaluated vaccine immunogenicity at 7th month after enrollment were included in the meta-analysis. Overall seroconversion rates among SLE participants were 89.3% (95%CI, 0.76-1.00) for HPV6; 92.4% (95%CI, 0.82-1.00) for HPV11; 96.4% (95%CI, 0.93-1.00) for HPV16; and 91.8% (95%CI, 0.85-1.00) for HPV18. Five studies were included in the qualitative analysis of vaccines safety. Pain at the injection site was the most common adverse event (AE). Just one study reported serious AE not related to the vaccine. Flare rate after HPV vaccination was 12,6% (95% CI, 0.04-0.21).

CONCLUSION

Few studies, small sample size, evaluated HPV vaccines in SLE women. Seroconversion rates in SLE women were like healthy women, but anti-HPV geometric mean titers (GMT) were slightly lower in SLE women. HPV vaccines were safe in this population.
