What are alternative treatments for Rheumatoid Arthritis (RA) in patients with Impaired Renal Function (kidney problems)?

From the Guidelines

For patients with rheumatoid arthritis (RA) and impaired renal function, hydroxychloroquine is a preferred initial treatment option due to its minimal kidney impact, as evidenced by recent guidelines 1.

Treatment Options

• Hydroxychloroquine can be used even in patients with renal impairment, making it a viable choice for those with kidney problems.
• Low-dose corticosteroids like prednisone (5-10mg daily) can help manage flares while being monitored for fluid retention.
• TNF inhibitors such as etanercept (Enbrel) and adalimumab (Humira) are generally considered safe for patients with kidney disease when dosed appropriately.
• Abatacept (Orencia) is another option with minimal kidney clearance.
• JAK inhibitors like tofacitinib may be used with dose adjustments based on kidney function.

Important Considerations

• It's essential to avoid NSAIDs and minimize methotrexate use as these can worsen kidney function.
• Regular monitoring of kidney function with blood tests is crucial while on these medications.
• Physical therapy, gentle exercise, and maintaining a healthy weight are important non-medication approaches that support joint health without kidney burden.

Personalized Treatment Plan

• The treatment plan should be personalized based on the severity of both the RA and kidney condition, with close coordination between rheumatology and nephrology specialists to balance effective RA control while protecting remaining kidney function, as recommended by the most recent EULAR guidelines 1.
• The 2019 update of the EULAR recommendations for the management of rheumatoid arthritis with synthetic and biological disease-modifying antirheumatic drugs provides the most current guidance on treatment strategies, emphasizing the importance of shared decision-making and personalized care 1.

From the Research

Alternative Treatments for Rheumatoid Arthritis (RA) in Patients with Impaired Renal Function

• Patients with rheumatoid arthritis (RA) and impaired renal function may require alternative treatments due to the potential nephrotoxicity of certain medications 2, 3.
• Etanercept, a tumor necrosis factor (TNF) inhibitor, has been shown to be a safe and effective treatment option for RA patients with chronic kidney failure 4.
• Other treatment options, such as leflunomide and COX-2 inhibitors, may also be considered for patients with impaired renal function 5, 6.
• However, the use of certain medications, such as methotrexate and NSAIDs, may need to be adjusted or avoided in patients with renal dysfunction to prevent adverse events 3, 5.

Medication Dosage Adjustments

• The dosage of certain medications, such as methotrexate, may need to be adjusted in patients with impaired renal function to prevent toxicity 5.
• The use of dosage adjustment formulas, such as the Cockcroft-Gault and abbreviated Modification of Diet in Renal Disease (aMDRD) study formulae, can help guide medication dosage adjustments in patients with impaired renal function 5.
• Regular monitoring of renal function and urine dipstick tests can help identify patients who require medication dosage adjustments 5.

Treatment Considerations

• The treatment of RA in patients with impaired renal function requires careful consideration of the potential risks and benefits of different medications 2, 3.
• A treat-to-target strategy, which aims to achieve remission or low disease activity, may help reduce the risk of renal manifestations in RA patients 3.
• The use of biologic medications, such as etanercept, may be considered for patients with impaired renal function who have not responded to other treatments 4, 6.
