Paradigm
• Inflammation is bad
• Inflammation is treatable
Note
• In early RA 90% of all HRUS lesions are small
• In late RA 63% of all HRUS lesions are small
i.e. majority of erosions small (esp. early)
Radiology will miss most cortical breaks
especially in early disease

Shift in Treatment Paradigm in RA
Disease modifying antirheumatic drugs- DMARDs
The main goal of the therapy – i.e “ tight control of the disease” should
01/25/2023 be achieved , no matter what approach is used. . 46
Commonly used DMARDs
Name Dose Onset of Monitoring Side effects

perimetry retinopathy,
myopathy, nausea
MTX 7.5- 25 mg once 1-2 Months Blood counts, LFT : Bone marrow

DMARDs –Shortcomings
Etanercept TNF blocker. 50mg subcutaneously once a week. May be given with MTX or as
monotherapy.
Adalimumab Fully humanized TNF blocker. 40mg sub- cutaneously every 2 weeks (fortnightly).
May be given with MTX or as monotherapy.
Anakinra IL-1 receptor anatagonist. 100mg subcutaneous once daily. May be given with
MTX or as monotherapy.
Rituximab (24 Depletes B lymphocytes. Used in combination with Methotrexate to treat severe
weeks) active RA with inadequate response or intolerance to other DMARDs including
one or more TNF inhibitor therapies. Infusions of 1000mg each spaced 2 weeks
apart.
