Opportunistic Infections

and Tuberculosis Risk

Management

Kevin L. Winthrop, MD, MPH Associate Professor, Divisions of Infectious

Diseases, Public Health, and

Preventive Medicine

Oregon Health & Science University

Learning Objectives

• Identify which patients have the highest

risk for infection and how this is modified

by DMARDs

• Define the risks of specific types of

opportunistic infections, and identify

appropriate screening and mitigation

strategies of these and other infectious risks

IMID Biologic Therapies

• TNF- 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 receptor antibody: tocilizumab

– Anti- IL12/IL23 antibody: ustekinumab

– Anti-IL-17A: secukinumab, Ixekizumab

• Small molecules (non-biologic)

– JAK inhibitor: tofacitinib

Singing in the ShowerCase #1

• 50 year old female, RA

– Met Opera Singer

– Prednisone 7.5mg, etanercept

• Recent increase in cough

– Bronchoscopy with Mycobacterium avium X1

– Recent switch from baths to 30-45 minute hot,

steamy showers

What To Do?

• Wait and see vs. “change the race-horse”

– Stop TNF? Start MTX?

– Switch biologic?

• Stop taking showers?

• Treat her M. avium?

Vaccines & Preventable Diseases

Case Study

• 52 year old female with rheumatoid

arthritis (RA)

• Current therapy (visit date October 2015)

– Methotrexate 25mg week

– Prednisone 10mg daily

• RA disease severity with little change

– Considering biologic therapy

Her Feelings About Vaccines

• Patient not enthusiastic about vaccinations

– “Have egg allergy”

– “My husband gets the flu from the flu shot”

– “They have mercury in them that can cause

Alzheimers disease”

PCV-13: CAPITA Trial

• PCV-13 Vs. placebo, Netherlands (n=85,000)

• Vaccine-type pneumococcal community-

acquired pneumonia

– 45.6% (22%-62.5%) efficacy

• Vaccine-type invasive pneumococcal disease

– 75% (41-91%) efficacy

MMWR, October 12, 2012; 61(40):816-9.

Influenza

• Inactivated annual vaccine for all

rheumatologist patients

– High dose Flu-Zone®?

– Quadrivalent

– “Egg allergy” not a contraindication

• 2016-2017 vaccine

– A/California/7/2009(H1N1)

A/Hong Kong/4801/2014(H3N2)

High Dose (HD) Flu > 65 Years Old

• HD Vs. Standard Dose (SD) (N=31,989)

• Outcome = lab-confirmed flu

– 228 (1.4%) HD Vs. 301 (1.9%) SD

– Relative efficacy, 24.2%

– Higher percentage of protective titers with HD

• SAEs similar between groups

– (8.3%) HD Vs. (9.0%) SD
