Brief Summary

Spondyloarthritis (SpA) and Rheumatoid arthritis (RA) are among the most common chronic inflammatory rheumatic diseases. Introduction of Tumor Necrosis Factor alpha inhibitors (TNFi) to the therapeutic strategy improved acute inflammation and pain, but a significant percentage of patients develop severe adverse events or are still non responders or incomplete responders to these expensive treatments. There is an urgent need to identify new predictors of biological therapy response. It has been described the role of microbiota in some rheumatic diseases, however, clinical trials are scarce. We hypothesized that microbiota or their metabolites may play a role in therapeutic response to TNFi.

Outcome Measures

Primary Outcomes (3)

  • Oral and gut microbiota characterization in axSpA and RA patients at baseline

    Before bDMARD

  • Oral and gut microbiota characterization in axSpA and RA patients at week 14

    14 weeks after start bDMARD

  • Disease activity measured by ASAS20 in axSpA and ACR20 in RA

    14 weeks after start bDMARD

Secondary Outcomes (10)

  • Changes in Erythrocyte Sedimentation Rate (ESR, measured in mm/h)

    Before bDMARD and 14-week after start bDMARD

  • Changes in High-sensitivity C-reactive protein (hsCRP, measured in mg/dL)

    Before bDMARD and 14-week after start bDMARD

  • Disease activity characterization using Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) in axSpA

    Before bDMARD and 14-week after start bDMARD

  • Disease activity characterization using Ankylosing Spondylitis Disease Activity Score - C-Reactive Protein (ASDAS-CRP) in axSpA

    Before bDMARD and 14-week after start bDMARD

  • Disease activity characterization using Disease Activity Score-28 for Rheumatoid Arthritis with C-Reactive Protein (DAS28-CRP) for RA

    Before bDMARD and 14-week after start bDMARD

  • +5 more secondary outcomes

Study Arms (3)

Sampling MethodNon-Probability Sample
Study Population

Patients with axSpA or RA according to ASAS and 2010 ACR/EULAR classification criteria, respectively, with indication to start bDMARD according to Portuguese Rheumatology Society.

You may qualify if:

  • Diagnosis of axSpA (according to ASAS classification criteria) or RA (according to 2010 ACR/EULAR classification criteria);
  • Indication for bDMARD therapy, according to the Portuguese recommendations for the use of biological therapies in patients with axSpA and RA;
  • Oral corticosteroids (equivalent to prednisolone ≤ 10mg/day) and/or nonsteroidal anti-inflammatory drugs allowed at stable dose ≥4 weeks before baseline;
  • Conventional DMARDs allowed at stable dose ≥12 weeks before baseline;
  • Ability to provide informed consent.

You may not qualify if:

  • History of rheumatic disorder other than axSpA or RA;
  • History of Inflammatory Bowel Disease;
  • Previous treatment with bDMARD;
  • Current pregnancy or breastfeeding;
  • Malignancy (except for completely treated squamous or basal cell carcinoma);
  • Any uncontrolled medical condition (e.g., uncontrolled diabetes mellitus, unstable ischemic heart disease);
  • History of any documented gastrointestinal disease or tract surgery leaving permanent residua (e.g., gastrectomy, bariatric surgery, or colectomy);
  • Intraarticular injections of extra-axial joints and tendons within 28 days before or at baseline;
  • Recent (\<3 months prior) use of any antibiotic therapy, current extreme diet (e.g., parenteral nutrition or macrobiotic diet), current consumption of probiotics.
