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...
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?
The dependence on the use of systemic glucocorticoids may indeed be a good reason to change treatment. Especially in patients with psoriatic arthritis. So, if patients are unable to stop systemic glucocorticoids and there are still treatment options for the patient, this could be tried. It is diffic...
In the treatment of osteoarthritis with low-dose radiation therapy is there data to support the claim that LDRT does not limit or preclude later orthopedic surgery?
At LDRT doses, the biological effects are anti-inflammatory and immunomodulatory rather than cytotoxic or fibrogenic, and there is no evidence of vascular injury, impaired cellular proliferation, or tissue destruction. Animal models and cellular studies provide robust evidence that LDRT at OA releva...
In patients with osteoporosis at high fracture risk, what factors most influence your decision to prescribe teriparatide versus abaloparatide?
Both abaloparatide and teriparatide are very effective anabolic agents to reduce vertebral and nonvertebral fracture risk in patients with osteoporosis (although clinical trials did not demonstrate reduction of hip fracture risk). The two agents are more similar than different and both induce an an...
Do you seek pathologic confirmation before proceeding with empiric immunosuppressive therapy in symptomatic patients with radiographic NSIP?
In general, getting lung biopsies is needed in a minority of people who have clear evidence of NSIP on HRCT. If there is any evidence to suggest a concomitant ARD, a biopsy will not typically be needed. In our combined ILD-Rheumatology clinic, we see these patients all the time and I can think of on...
Do you think we can extrapolate the results of TOGETHER-PsA and expect similar results and safety when adding Tirzepatide to another IL-17 inhibitor or to a bDMARD with different mechanism of action?
Yes and no. We don't have hard randomized controlled trial (RCT) data with biologic disease-modifying antirheumatic drugs (bDMARDs) other than ixekizumab at present. However, if we extrapolate data from prior weight loss studies in psoriatic arthritis (PsA) and psoriasis (PsO), it would be reasonabl...
Do you consider metformin as a disease-modifying adjunct in the management of patients with OA, particularly in those with comorbid metabolic syndrome or type 2 diabetes?
Based on the Pan et al., PMID 40274279, and the broader literature, I would not yet formally classify metformin as a disease-modifying osteoarthritis drug (DMOAD), but the evidence is increasingly compelling, particularly in the metabolic osteoarthritis (OA) phenotype.This randomized controlled tria...
How do you approach the treatment of patients with Ehlers-Danlos hypermobile type with chronic muscle spasms with minimal exertion?
You accept that EDS is a genetic connective tissue disorder and not a rheumatological issue. You check hormones and vitamins to ensure they are in range: especially Mg with the cramps. Some EDS patients find working with an EDS physical therapist is beneficial: the goal being to learn how to exercis...
How long would you recommend that a patient continues guselkumab prior to deciding that the therapy is not effective?
Many trials have a placebo-controlled period of 12-24 weeks. Thereafter, all patients receive active treatment. Even if the original treatment allocation remains unknown to the patient and doctor, they know that from that moment on, everyone receives active treatment. This will have an influence on ...
How do you approach the workup of pauci-immune glomerulonephritis?
When a kidney biopsy reveals a pauci-immune GN, the Ddx must extend well beyond classic AAV and infective endocarditis. For instance, anti-GBM disease should remain high on the list, as up to 25% of these patients present with a "dual-positive" ANCA, and the characteristic linear IgG staining on IF ...
