Were the patients enrolled in the SEAM-RA trial prior methotrexate monotherapy non-responders?
Yes, presumably at one time, most of these patients were methotrexate non-responders because otherwise, it’s unlikely they would have required escalation to TNFi. Clinicians would typically not add TNFi therapy unless the patient had first failed DMARDs (i.e., methotrexate in this case). It is impor...
Is there any role for immunosuppressive therapy in patients with primary Sjogren's disease with severe pulmonary artery hypertension without ILD findings?
PAH (WHO Class I PH) in/and SJD is not a common relation, and as such would Rx as we Rx regarding PAH in PSS? The pathophysiology of PSS is, at least in part, a vasculopathy that SJD may not share. The question is, however, specific regarding Primary SJD and the assumption then is that this is not a...
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 time concurrent therapy with rituximab and IVIG?
Rituximab has about the same half-life as regular IgG. If the regular IVIG treatment can be delayed, it will be less likely to increase the catabolism of Rituximab. If the regular IgG is given at 3-4 week intervals, I would give the Rituxan halfway between IVIG doses. Complement is needed for optima...
In a patient with low titer +anti-SAE antibody and known ILD, but no other clinical features of dermatomyositis, how would you approach further testing or would you treat the patient as dermatomyositis associated ILD?
When someone with ILD has an isolated biomarker without other clinical features associated with that biomarker, I have to ask myself these questions: first, is the biomarker simply a false positive because I have tested a plethora of biomarkers and second, is ILD the initial or only manifestation as...
What is your preferred first-line treatment for chronic fatigue in patients with long COVID-19?
Assuming that a thorough workup for other causes of fatigue (anemia, thyroid dysfunction, sleep apnea, etc.) has been performed and is negative, no single medication has been proven by a randomized placebo-controlled trial to help chronic fatigue in PASC. Anecdotally, my colleagues who treat PASC ha...
How would you approach diagnosis of a patient with recurrent episodes of abdominal pain, severe myalgias, low grade fevers and urticaria?
Without the mEFV variant, from a rheumatologist viewpoint, the differential includes IBD, a periodic fever syndrome such as FMF or FCAS, and MCAS. Therefore, I would consider that workup with genetic testing (anyone can send!), fecal calprotectin, and MCAS eval with A/I. I don't think of urticarial ...
What biomarkers or patient characteristics do you feel best predict response to B cell depleting therapies in a patient with Sjogren's?
At present, it may depend on the Sjogren's phenotype being treated with B-cell depleting therapies. If it is vasculitis with or without cryo, cryoglobulins, rheumatoid factor, and complements are helpful, along with inflammatory markers (ESR/CRP). I also note the level of total IgG, if elevated, may...
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...
Do you have safety concerns when prescribing GLP-1 medications in patients on corticosteroids or immunosuppressive therapy?
I think we need to be particularly careful when co-prescribing with systemic corticosteroids because of the risk of sarcopenia. We know that rapid weight loss is accompanied not only by a loss of fat tissue but also of muscle. Corticosteroids can also have myotoxicity and cause muscle atrophy. I the...
