conducted by UCB, Roche, Astellas, Lilly, Janssen, GalapagosOHSU

IMID Biologic Therapies• TNF-α inhibition

– Infliximab, adalimumab, golimumab, certolizumab (monoclonal antibodies)

– Etanercept (soluble p75 receptor)• Other Biologics

– CD4 co-stimulation modulator: abatacept – B-cell (CD20+) antibody: rituximab– Anti-IL-6: tocilizumab, sarilumab– Anti- IL12/IL23 antibody: ustekinumab– Anti-IL-17A: secukinumab, ixekizumab

• Small molecules (non-biologic)– JAK inhibitor: tofacitinib, baricitinib, upadacinitib

OHSU

“Low Dose” Corticosteroids and Infections

• Always a risk in observational studies– Limited RCT data suggests no increased risk

• What is the truth?– Confounding due to disease activity

versus true increased riskOHSU

Psoriasis and TNFi

• Started on Adalimumab• Constitutional symptoms worsen• Worsened thumb abscesses• Cough and back pain

– Sputum grew M. tuberculosis

– Epidural abscess grew M. tuberculosis• Disseminated TB diagnosed

OHSU

Treatment and Course

• Treated with 4 drugs • Starting 2-3 months into therapy

– Para-spinal abscess at C6, T2, T6, T8– Required multiple drainage/laminectomies– Recurrent abscess at left thumb

• Over next 6 months with recurrent abscesses– Month 4---epidural abscess--AFB culture negative– Month 5---finger---AFB culture negative– Month 6 ---epidural abscess---AFB culture

negative

How to Mitigate Infectious Risk?

• Use lowest dose biologic/JAK possible• Avoid corticosteroids• Laboratory monitoring• Screen for TB, HBV, HCV• Vaccinate

– Influenza, pneumococcus, shingles

OHSU

VERVE Trial

• All active anti-TNF users (most RA)– N=617

• 1:1 live shingles vaccine versus placebo• Results

– Immunogenicity diminished as expected– Safety---No cases of vaccine HZ in 42 days
