Q

What is 4th line management for Rheumatoid Arthritis?

A

MTX plus Rituximab

This is considered for patients who do not respond to other therapies.

17
Q

What is used to induce remission of a flare in Rheumatoid Arthritis?

A

Oral / IM Prednisolone

Corticosteroids are effective for managing acute exacerbations.

18
Q

What are the side effects of Methotrexate (MTX)?

A

Pneumonitis, Pulmonary fibrosis, Hepatotoxicity

Monitoring for respiratory symptoms is important.

19
Q

What are the side effects of Sulfasalazine (SSZ)?

A

Reversible reduced Sperm count, orange urine

These side effects may impact patient compliance.

20
Q

What are the side effects of Levoflunamide?

A

HTN, Peripheral neuropathy

Patients should be monitored for these potential complications.

21
Q

What are the side effects of Hydroxychloroquine?

A

Blue grey skin, retinopathy, hair lightening

Regular eye examinations are necessary during treatment.

22
Q

What are the side effects of Biologics?

A

Reactivation of TB, hence must request CXR

Screening for TB is crucial before starting Biologics.

23
Q

What is Felty’s Syndrome?

A

RA + splenomegaly + neutropenia

This syndrome is a rare complication of Rheumatoid Arthritis.

24
Q

What are some complications of Rheumatoid Arthritis?

A

Respiratory (Pulmonary fibrosis, bronchiolitis obliterans, MTX pneumonitis), Ocular (Episcleritis, scleritis), Osteoporosis, IHD, Felty’s

These complications can significantly affect patient quality of life.

25
What drugs for Rheumatoid Arthritis are safe in pregnancy?
SSZ and Hydroxychloroquine ## Footnote These medications are generally considered safe for use during pregnancy.
26
What are some poor prognostic factors of Rheumatoid Arthritis?
RF, anti-CCP, HLA DR4 positive, male, younger onset, poor symptoms on initial presentation ## Footnote These factors suggest a more aggressive disease course.
27
What are the drugs that interact with methotrexate and what are the side effects?
Methotrexate + trimethoprim = pancytopenia Methotrexate+ Co-trimoxazole = pancytopenia Methotrexate + high dose aspirin = methotrexate toxicity
