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...
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 ...
Is there a period of time after which you would not resume ICI after a patient has had an irAE and required a prolonged steroid taper?
Typically if a patient has required treatment with steroids for four to six months, it was because their irAE was significant (grade 2-4) and refractory to initial treatment. If the patient received combination immunotherapy, such as anti-CTLA-4 and anti-PD-1 agents, one could consider resuming the ...
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 ...
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...
Does SI joint erosion on MRI pelvis push you to use TNF inhibitors over NSAIDs as first line for axial spondyloarthritis?
A decision to consider TNFi (or another targeted therapy) over initial NSAID therapy depends primarily on disease severity, symptom burden, and impact on quality of life, presence of significant peripheral disease (where csDMARDs have already failed or resulted in side effects), contraindications or...
What factors lead you to recommend a JAK inhibitor as second-line therapy in a patient with radiographic axSpA who has had a primary non-response to a TNF inhibitor, before trying an IL-17 inhibitor?
This is an excellent question, which requires not just a treatment plan but also a revelation of how we should be making patient management decisions in Spondyloarthritis (SpA). My initial reaction is that primary non-response to a TNFi is not the usual story; if this truly happens, I recommend re-e...
