Based on Together-PsA, would you favor starting all patients with PsA and comorbid obesity on combination therapy with tirzepatide + bDMARD or will you pursue initial bDMARD monotherapy with tirzepatide rescue in the event of bDMARD non-response?
In looking at the Together-PsA data, this was a challenging cohort to treat, and a reasonable increase in treatment response was seen with combination therapy. Multiple studies have shown that obese psoriatic arthritis (PsA) patients are less likely to achieve minimal disease activity (MDA) and have...
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...
What is the role of the rheumatologist in recommending and providing GLP-1 medications to their patients given the benefits across many disease domains including osteoarthritis?
Obesity has long been discussed in the literature as the most modifiable risk factor for knee osteoarthritis pain and progression, with a reduction in knee OA attributed to the decrease in mechanical load. But for the last decade, there has been much attention placed on the impact of metabolic facto...
Are the results of the SEAM-RA trial generalizable to other TNF inhibitors given the differences in immunogenicity?
This is a great question, and an important one because different TNF inhibitors have different immunogenicity and patients can make anti-drug antibodies that can effectively neutralize the drug and render it a less effective treatment option. This tends to happen more with some molecular constructs ...
Do you routinely apply the 2010/2011 ACR symptom-based diagnostic criteria for fibromyalgia in your practice, or do you continue to use the 1990 tender point examination to make the diagnosis?
I don’t use tender point counts in my practice: they were discarded after the 1990 criteria for many reasons, including poor inter-rater reliability and the sort of nebulous nature of what was really being measured. The ACR 2016 criteria reference this very issue, noting that some have described ten...
In a young patient with relapsing polychondritis and aortitis which has led to severe aortic valve regurgitation, is there any preference for a mechanical versus bioprosthetic valve replacement?
There is no data specifically on valve replacement for RP. If the patient can be safely anticoagulated, a mechanical valve would be likely better since it is a young patient. Data from TAK regarding valve replacement suggest subsequent complications are less likely when the aortic root is also repla...
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...
What is the most appropriate next step in management for a patient with dermatomyositis who is maintained on methotrexate 25 mg weekly but develops disease flare when prednisone is tapered below 10 mg daily and is unable to receive IVIG?
The fact that the patient cannot taper prednisone below 10 mg indicates that methotrexate alone, while has some effect, is not sufficient to control the disease. There are several options, depending on the severity of each organ involvement. Since the joints are affected, I would favor an agent that...
Are there particular subsets of AAV patients in which avacopan is more effective?
The following answer was jointly drafted by Dr. Peter Merkel and Dr. David Jayne:Patients in the ADVOCATE trial were stratified at entry according to time of diagnosis (new/relapsing), diagnosis (GPA/MPA), ANCA serotype (PR3/MPO), and background immunosuppressive (cyclophosphamide/rituximab) with re...
How do you approach screening for ILD in patients with a diagnosis of MCTD given the recommendation discrepancies between the most recent EULAR and ACR/CHEST guidelines?
Another excellent question! While the EULAR guidelines treat MCTD as SSc-equivalent and suggest universal screening, ACR/CHEST guidelines suggest risk-stratified screening with emphasis on symptoms, PFT abnormalities, and high-risk phenotypes.Prevalence of ILD in MCTD can be high, in the range of 30...
