The global prevalence of rheumatoid arthritis (RA) is increasing, resulting in an increased use of Janus kinase (JAK) inhibitors. Several cases of varicella-zoster virus (VZV) pneumonia in patients with RA have been reported. However, to our knowledge, no reports have demonstrated conclusive evidence of VZV reinfection in this patient population.

Background: Despite the autoimmune nature of psoriasis, the potential association between psoriasis and interstitial lung disease (ILD) remains underexplored. This study aimed to investigate the frequency and clinical features of ILD in patients with psoriasis and propose a new conceptual framework of "ILD associated with psoriasis".

Methods: A retrospective analysis of 117 patients with psoriasis was conducted, excluding those without chest imaging prior to methotrexate or biologic use and those with other comorbidities leading to ILD.

Patients with autoimmune inflammatory rheumatic diseases (AIIRD) are potentially at a higher risk of contracting the SARS-CoV-2 virus and have poorer outcomes of the infection as a result of their immunocompromised state due to the nature of the underlying autoimmune conditions and immunosuppressant use. mRNA-based vaccines provide a novel approach to establishing immunity against SARS-CoV-2. However, the implications of toll-like receptors (TLRs), type I interferon (IFN) and pro-inflammatory cytokines raise concerns on disease severity and inefficient immune response following mRNA vaccination.

Article Synopsis
  • - Varicella-zoster virus causes chicken pox and shingles, and while usually mild in kids, it can be serious in immunocompromised individuals.
  • - An 11-year-old boy on methotrexate (not typically immunosuppressive) developed a severe varicella infection that led to pneumonia.
  • - He was treated with high-dose acyclovir and intravenous immunoglobulin (IVIG), which helped him recover completely thanks to their effectiveness in immunocompromised patients.

Article Synopsis
  • This study explored the adverse events (AEs) related to COVID-19 vaccination in patients with rheumatoid arthritis (RA) as part of the COVAD-2 study, which surveyed participants from February to June 2022.
  • It included 7203 participants, including 1423 RA patients, and found that RA patients reported higher rates of both major and minor AEs compared to healthy controls, and even more when compared to those with other autoimmune diseases.
  • Active RA significantly increased the risk of major AEs and hospitalization, while patients on certain medications like methotrexate or TNF inhibitors experienced fewer AEs than those not on these treatments.
