The bacterial diversity in lesional and nonlesional skin of patients with psoriasis (PsO) with or without psoriatic arthritis (PsA) was significantly lower than that of healthy control skin, based on data from 74 individuals.

Previous studies in humans and animals have suggested that microbes play a role in PsO pathogenesis, but microbial analyses of PsA are lacking, wrote Alba Boix-Amorós, PhD, of the Icahn School of Medicine at Mount Sinai, New York, and colleagues.

“The passage from PsO to PsA may, in part, be driven by microbial triggers, which deserves further investigation,” they wrote.

In a study published in Annals of the Rheumatic Diseases, the researchers recruited 23 patients with PsO and 31 with PsA from the dermatology and rheumatology clinics at the NYU Grossman School of Medicine/NYU Langone Health in New York. An additional 20 healthy individuals with no history of PsA or PsO were recruited from within NYU to serve as controls. All participants were aged 18 years and older, and more than 75% were White. Males made up 65.4%, 47.8%, and 55.0% of the PsA, PsO, and control groups.

The researchers collected skin swabs from lesional and nonlesional skin of individuals with PsO and PsA and from the upper and lower extremities of the healthy controls. The microbiota analysis included 148 samples that were analyzed using 16S rRNA sequencing.

The microbiome diversity was significantly greater in healthy skin, compared with lesional and nonlesional psoriatic skin (P < .05 for both). Specifically, levels of Cutibacterium and Kocuria were significantly higher in healthy skin than in psoriatic skin (P = .016 and P = .011, respectively), while psoriatic skin showed higher levels of Staphylococcus.

No significant microbiome differences were noted between lesional and nonlesional PsO and PsA samples. The finding that the microbiome of nonlesional psoriatic skin was more similar to lesional psoriatic skin than to healthy skin was unexpected, and suggests the development of microbial dysbiosis in psoriatic skin independent of the presence of lesions, the researchers wrote.

The researchers also found that levels of Corynebacterium in nonlesional PsA samples were significantly elevated, compared with nonlesional PsO samples (P < .05), which suggests a possible role for the microbe as a biomarker for disease progression, the researchers said.

“One important application of these data is the potential development of therapeutic options for the treatment of psoriatic disease and/or the prevention of PsA,” the researchers wrote in their discussion.

The findings were limited by several factors, including the combination of samples from upper and lower extremities and the exclusion of data from the scalp, the researchers noted. Other limitations included the use of only 16S rRNA gene sequencing, which presents a less comprehensive view of the microbiome, they said.

However, the results support the role of the skin microbiome in psoriasis pathogenesis, with details on microbiota across the psoriatic disease spectrum, they said.

The study received no outside funding. Dr. Boix-Amorós had no financial conflicts to disclose. Several coauthors disclosed financial relationships with pharmaceutical companies including Janssen, AbbVie, Bristol-Myers Squibb, Johnson & Johnson, Eli Lilly, Pfizer, Novartis, Sanofi, and UCB.

Key clinical point: Subcutaneous vs intravenous infliximab demonstrated improved efficacy in patients with rheumatoid arthritis (RA) who were inadequate responders to methotrexate (methotrexate-IR).

Major finding: At week 30, subcutaneous vs intravenous infliximab led to significantly lower Disease Activity Scores in 28 joints-C-reactive protein (DAS28-CRP; mean 3.07 vs 3.58; P  =  .0001) and significantly higher proportion of patients achieving DAS28-CRP low disease activity and remission (53.3% vs 38.5%; P  =  .0062), with no significant between-group difference after the switch to subcutaneous infliximab.

Study details: This post hoc analysis of a phase 3 trial included 339 patients with active RA who were methotrexate-IR and were randomly assigned to receive subcutaneous or intravenous infliximab; patients assigned to receive intravenous infliximab switched to subcutaneous infliximab from week 30 to 54.

Key clinical point: Cumulative local joint inflammation over time was significantly associated with radiographic joint damage progression in the same joint in patients with early rheumatoid arthritis (RA) who were treated to a target disease activity score (DAS) of ≤2.4 for 10 years.

Major finding: Cumulative joint swelling was positively associated with local joint damage progression in the same joint (β 0.14; 95% CI 0.13-0.15). Each additional visit for joint swelling increased the joint damage score by a 0.13 unit and frequency of joint swelling in same vs other joints better predicted local joint damage progression (P < .001).

Study details: This post hoc analysis of the BeSt study included 473 patients with early RA who were randomly assigned to receive sequential monotherapy, step-up combination therapy, or initial combination therapy with methotrexate with or without sulfasalazine+prednisone or infliximab, with treatment intensification every 3 months until DAS ≤2.4 was achieved.

Disclosures: The BeSt study received funding from the Dutch College of Health Insurances and others. No competing interests were declared.

Key clinical point: “Plants for Joints” (PFJ), a 16-week multidisciplinary lifestyle program based on whole food plant-based diet, physical activity, and stress management in addition to usual care, significantly improved disease activity compared with usual care alone in patients with rheumatoid arthritis (RA) and low-to-moderate disease activity.

Major finding: After 16 weeks, patients receiving PFJ vs usual care alone had a greater reduction in disease activity score of 28 joints (DAS28; mean difference −0.90; P < .0001) and were more likely to achieve DAS28 <2.60 (odds ratio [OR] 4.6) and European Alliance of Associations for Rheumatology Good Response (OR 4.3; both P < .001). No serious adverse events were reported.

Study details: This randomized controlled trial, “Plants for Joints,” included 77 patients with RA and low-to-moderate disease activity who were randomly assigned to receive PFJ intervention plus usual care or usual care alone.

Disclosures: The trial was funded by Reade (The Netherlands) and other sources. The authors declared no conflicts of interest.

Key clinical point: Tapering glucocorticoids to doses >2.5 mg/day was effective with no increase in the risk for flare, whereas tapering to doses ≤2.5 mg/day significantly increased the risk for flare in patients with rheumatoid arthritis (RA) receiving biologic disease-modifying antirheumatic drugs (bDMARD).

Major finding: Discontinuation of glucocorticoids (adjusted odds ratio [aOR] 1.45; 95% CI 1.13-2.24) and tapering of glucocorticoid dose to 0-2.5 mg/day (aOR 1.37; 95% CI 1.06-2.01) were significantly associated with an increased risk for flare, whereas tapering of glucocorticoid dose to >2.5 mg/day did not significantly increase the risk for flare compared with no tapering.

Study details: The data come from a case-crossover study including 508 patients with RA receiving bDMARD with or without glucocorticoids, of which 52.5% of patients reported at least one flare.

Key clinical point: Patients with rheumatoid arthritis (RA) who were males or had multiple comorbidities were less likely to achieve quality care markers, thereby highlighting the need to prioritize early treatment in the vulnerable patient population.

Major finding: Among patients with RA, males (odds ratio [OR] 0.72; 95% CI 0.72-0.73) and those with a Rheumatic Disease Comorbidity Index >2 (OR 0.88; 95% CI 0.86-0.90) were less likely to receive a rheumatologist referral, with findings being similar for annual physical examination. Additionally, the presence of diabetes was associated with reduced odds of receiving a rheumatologist referral (OR 0.77; 95% CI 0.76-0.78) or annual physical examination (OR 0.59; 95% CI 0.56-0.62).

Study details: This retrospective observational cohort study included 581,770 patients with incident RA.

Key clinical point: Current use of oral glucocorticoids significantly increased the risk for Staphylococcus aureus bacteremia (SAB) in a dose-dependent manner in patients with rheumatoid arthritis (RA), but the absolute risk was low with biological disease-modifying antirheumatic drug (bDMARD) use.

Major finding: Relative risk for SAB was 2.2-fold (adjusted odds ratio [aOR] 2.2; 95% CI 1.3-4.0) and 9.5-fold (aOR 9.5; 95% CI 3.9-22.7) higher with current use of ≤7.5 and >7.5 mg/day prednisolone-equivalent oral glucocorticoids, respectively. The number needed to harm was approximately 10 times higher with the current use of bDMARD vs >7.5 mg/day oral glucocorticoids (1172 vs 110).

Study details: This nested case-control study included 180 patients with first-time SAB who received glucocorticoids or bDMARD and 720 age- and sex-matched control individuals from a cohort of 30,479 patients with RA.

Disclosures: This study was supported by The Danish Rheumatism Association (TDRA) and Beckett-Fonden. Several authors reported ties with various sources, including TDRA and Beckett-Fonden.

Key clinical point: The probability of continued use of glucocorticoids after bridging was low among patients with rheumatoid arthritis (RA), with a shorter oral bridging schedule and lower initial dose being associated with fewer patients taking glucocorticoids at 18 months after bridging.

Major finding: The probability of using or restarting glucocorticoids decreased from 0.18 at 1 month to 0.07 at 6, 12, and 18 months of ending glucocorticoid bridging therapy. A longer duration of bridging schedule (odds ratio [OR] 1.14; 95% CI 1.05-1.24) and higher initial glucocorticoid dose (OR 1.04; 95% CI 1.01-1.06) were associated with more patients taking glucocorticoids at 18 months after bridging.

Study details: This individual patient data meta-analysis of seven clinical trials included 1653 patients with newly diagnosed RA, undifferentiated arthritis, or a high-risk profile for persistent arthritis who received glucocorticoids bridging therapy as initial treatment.

Disclosures: This study did not receive any specific funding. Several authors reported ties with various sources.

Key clinical point: Methotrexate use before conception increased the risk for pregnancy losses and abortion in childbearing-age women with rheumatoid arthritis (RA), with the risk for elective termination of pregnancy (ETOP) being significantly higher with methotrexate use in the period close to conception.

Major finding: Methotrexate use any time before conception was significantly associated with a higher risk for pregnancy losses (adjusted odds ratio [aOR] 2.22; P < .001) and abortion (aOR 1.76; P < .01) in women with vs without RA, with the risk for ETOP being almost 4-fold higher with methotrexate use in the 3-month window before conception (aOR 4.77; P < .05).

Study details: Findings are from a retrospective cohort study including childbearing-age women with RA who did (n = 223) and did not (n = 323) receive methotrexate and those without RA who did not receive methotrexate (n = 1690).
