Human papillomavirus vaccine safety in systemic lupus erythematosus patients

Systemic lupus erythematosus following human papillomavirus vaccination: A case-based review

Systemic lupus erythematosus (SLE) is a heterogeneous systemic autoimmune diseases (AIDs) with many pathogenic factors, ranging from genetic to epigenetic to environmental. The human papillomavirus (HPV), a viral infectious agent, is a common contributor to the onset and exacerbation of SLE. HPV infections are more prevalent among SLE patients than healthy individuals, bringing about a substantial need for treatment. While HPV recombinant gene vaccines are accepted as a universal method for infection prevention, they pose a risk for adverse events such as fever, joint pain, and rashes. In rare cases, they might even trigger AIDs such as SLE, especially in patients with a personal or family history of such diseases. In this article, we provide a report of a case of SLE onset following HPV vaccination and a review of 11 similar cases. An analysis of 12 patients revealed that 7 cases of SLE developed between 3 weeks and 2 months post-vaccination. Symptoms of SLE generally manifest as fatigue, fever, joint pain, and myalgia. Two patients had lupus nephritis, 2 showed central nervous system involvement, including abnormal behavior and epileptic seizures, and 1 had intestinal pseudo-obstruction. All patients showed rapid remission with glucocorticoid and immunosuppressive therapy and remained stable during several months of follow-up.

SARS-CoV-2 vaccines in patients with SLE

As the Moderna (mRNA-1273) and Pfizer/BioNTech (BNT162b2) vaccines become available to patients with autoimmune diseases and SLE, practitioners will have to inform them about the safety and efficacy of these vaccines. Here we discuss the challenges of applying vaccine data to patients with autoimmune diseases and the evidence available in the literature that may help in the decision process.
