How should the results of the ADVOCATE trial be applied in AAV patients who receive rituximab induction and maintenance therapy?
The following answer was jointly drafted by Dr. Peter Merkel and Dr. David Jayne:The data from ADVOCATE indicate that patients with granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) treated with avacopan 30 mg twice daily and prednisone placebo were able to achieve remission w...
For a patient with suspected post-streptococcal reactive arthritis who does not meet criteria for acute rheumatic fever and has a normal echocardiogram at presentation, do you prescribe 1 year of antibiotic prophylaxis?
This is a loaded question. Post-Streptococcal reactive arthritis (PSRA) plagued me during my fellowship (many moons ago). There is a fine line between PSRA and rheumatic fever (RF). We rarely see RF in the United States anymore. If I'm convinced it is PSRA and not RF (e.g., RF migratory arthritis qu...
In patients with severe osteoporosis, history of retinal artery occlusion, and hypercalciuria, would you favor PTH analogue therapy or Evenity?
Assuming that PTH and vitamin D are normal, neither. Chlorthalidone is the treatment of choice in this scenario. Chlorthalidone is usually better than HCTZ, as HCTZ often must be given BID, whereas chlorthalidone can be given daily. I have seen very large improvements in BMD with thiazide therapy, o...
Should the use of avacopan be limited to those patients at increased risk of steroid toxicity given the anticipated high cost of this medication?
Once Avacopan is available for clinical use in the treatment of patients with AAV, providers will need to carefully weigh risks and benefits of the medication while considering other factors including cost.The ADVOCATE trial used a novel glucocorticoid toxicity index that captures common GC-related ...
Before re-challenging a patient with ICI after grade 1-2 pneumonitis, do you re-image to confirm resolution of pneumonitis?
Grade 1 pneumonitis is defined as confined to one lobe of the lung or <25% of the total lung parenchyma, while grade 2 pneumonitis is defined as involving more than one lobe of the lung or 25-50% of the lung parenchyma. Grade 1 pneumonitis is typically an incidental finding on CT in an asymptomatic ...
How do you interpret treatment response in the DISCOVER-2 Trial when patients were allowed to remain on up to 10mg of prednisone equivalent for disease control while on guselkumab?
If patients were on less than or equal to prednisone 10 mg, they could continue that in the background during the trial, but note that only 20% of patients were on prednisone, a much lower figure than a typical rheumatoid arthritis trial, which is consistent with the point that rheumatologists shy a...
What is in the differential diagnoses for isolated bilateral tarsometatarsal joint erosions in the absence of other clinical or serologic evidence of systemic inflammatory arthritis?
Isolated tarsometatarsal (TMT) joint erosions in the absence of other clinical or serologic evidence of an inflammatory arthritis are distinctly unusual. The usual culprits for erosions at the TMT joints include rheumatoid arthritis, spondylarthritis such as psoriatic arthritis, and erosive osteoart...
Do you recommend allopurinol desensitization in gout patients who develop a rash on allopurinol therapy?
I don't recommend desensitization for allopurinol-allergic patients. There was a time when this made sense due to the lack of a viable alternative therapy. The process is cumbersome in a private practice setting and not as simple as providing the patient with a prescription for febuxostat.Febuxostat...
In patients with a history of retinal vein occlusion, how should the risk of recurrent thromboembolic events influence the selection of osteoporosis therapies?
The FDA-approved prescribing information for raloxifene explicitly lists retinal vein thrombosis alongside deep vein thrombosis and pulmonary embolism as contraindications.
How has the new data regarding long-term follow-up of degenerative meniscal tears vs surgery changed your management approach in these patients?
Degenerative meniscus tears are a common finding on MRI in our older patients. A challenge lies in determining if that finding is the cause of the patient's symptoms. When deciding whether to send for surgical consultation, I query about mechanical symptoms (catching, locking, or giving way) and/or ...
