Do you use naltrexone in your patients with fibromyalgia?
I do not use low-dose naltrexone as a first-line agent for patients with fibromyalgia. Well-designed RCTs (Due Bruun et al., PMID 38258677; Bested et al., PMID 38226027) have not shown significant improvements in pain or other outcomes in the overall population of patients with fibromyalgia. That sa...
In a postmenopausal woman who is an avid marathon runner with no prior history of fractures, how would you approach treatment if DEXA shows severe osteoporosis at the distal radius (T-score −4.1) but only osteopenia at the hip and lumbar spine?
I would also make sure there was no error. I had a patient who had similar results, and it was a machine error- the machine was not calibrated correctly.
When would you consider referring a patient with suspected cardiac sarcoidosis based on PET and MRI for endomyocardial biopsy given degree of patchy involvement, as opposed to initiating empiric immunosuppressive therapies?
I would avoid initiating empiric immunosuppressive therapies without a firm diagnosis of sarcoidosis. I will mention however that the latest Japanese Circulation Society criteria for the diagnosis of sarcoidosis do include criterion for the non-invasive diagnosis of likely cardiac sarcoidosis based ...
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...
How often do you draw screening ANAs for discoid lupus?
Because a positive ANA is associated with an increased risk of progression to SLE in patients with discoid lupus, I routinely check an ANA at the initial visit in virtually all patients. If negative, I repeat it only if new symptoms concerning systemic involvement arise (e.g., joint pain, cytopenias...
How would you approach the evaluation and management of a patient with rheumatoid arthritis receiving leflunomide who presents with progressive peripheral pulmonary cavitary nodules, with biopsy revealing necrotizing granulomatous inflammation?
Given the association between leflunomide and nodules with necrosis and giant cells (though quite rare), I would consider stopping leflunomide and moving to another agent. I would, of course, make sure that cultures are negative on those nodules, given it could be mycobacterial, fungal, or even GPA.
How do you explain the concept of CAR-T therapy and why it may work to patients with autoimmune disease who are interested in pursuing a clinical trial?
In full transparency, I have not personally obtained informed consent from a patient immediately before CAR-T or a related cellular therapy. My center has a highly active immune therapeutics program, however, and I have spoken and written extensively about this area. I also serve on our health syste...
Are there clinical, laboratory, or imaging features that can help distinguish primary Sjögren’s syndrome from secondary Sjögren’s in patients with overlapping inflammatory arthritis or positive rheumatoid factor?
Such a good query. I don't really know, as associated SjD has been understudied. In my experience, associated Sjogren's does not look that different from Sjogren's alone. We have seen high ocular staining scores and markedly reduced unstimulated salivary flow in associated SjD (SLE, RA). In SjD, the...
Can you use leflunomide and rituximab in a patient with both multiple sclerosis and rheumatoid arthritis?
It is rare for a patient to have both diseases, but immunosuppressive therapy can be used for the management of both conditions. A study published in 2021 investigated the use of a combination of rituximab and leflunomide in rheumatoid arthritis (Behrens et al., PMID 33738492). Rituximab has previou...
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 ...
