How do you approach anticoagulation in a woman with SLE who is planning pregnancy, has persistently positive isolated anticardiolipin IgA and anti-β2 glycoprotein I IgA antibodies and a prior history of a provoked DVT after prolonged air travel?
I consider persistently positive IgA anticardiolipin and anti-β2 glycoprotein antibodies just as relevant as IgG/IgM subclasses. Moreover, phosphatidylserine antibodies are also relevant, if this patient could be tested for that as well.
In light of promising results of hydroxychloroquine in COVID-19, should we consider using it prophylactically in cancer patients, especially if immunocompromised?
At this time, as there is no good evidence available, I would not recommend the use of hydroxycholoroquine prophylactically in cancer patients. It is unclear whether it would prevent contagion, probably not, and we still don't know if it will have any effect on the course of COVID-19. We expect ther...
What is your approach to refractory oral ulcers in SLE?
I echo @ Cuoghi Edens thoughts! Failure of HCQ does not mean refractory disease. Oral ulcers in SLE often correlate with underlying disease activity and their presence signals a better need for disease control. I would consider escalation to a systemic DMARD, such as MMF, MTX, anifrolumab, or bel...
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...
What is your approach to screening for malignancy in dermatomyositis patients who do not have a high risk antibody profile and whose disease responds well to treatment?
This is a great question and one that is very relevant to our clinical practice. Different myositis specific and associated antibodies seem to carry different risks in their associations with cancer. My colleague, Dr. Alexander Oldroyd, has written our current guidelines on cancer screening for pati...
How would you define failure of anabolic therapy for severe osteoporosis and when would you consider ordering a second round of Evenity or PTH analogue therapy?
“Failure” of any therapy is often in the eyes of the beholder. The most efficient way to determine if there is anabolic activity is to measure a serum PINP (does not need fasting) and, for the PTH anabolic recheck, the PINP 2-3 months later. IF the delta is >10, you can be confident there is more pr...
What is your approach to further workup and treatment of abdominal aortitis found on imaging in asymptomatic individuals with elevated inflammatory markers?
The differential diagnosis of abdominal aortitis would include giant cell arteritis (we do not know the age of this patient), Takayasu arteritis, IgG4-related disease, Behcet's disease or other systemic rheumatic diseases (RA, SLE, ANCA-associated vasculitis - although less likely since this individ...
How long after initiation of steroids and immunosuppressive therapy does muscle biopsy remain reliably informative in the setting of suspected inflammatory myopathy?
I don't think there is any definitive, well-validated answer here. Certainly, obtaining a biopsy within ~2 weeks of initiating therapy, in my experience, has clearly not affected the histopathologic findings that would be characteristic of dermatomyositis, necrotizing myopathy or autoantibody-associ...
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...
Do you screen for cardiac disease in patients with dermatomyositis in the absence of symptoms?
I don't typically evaluate for cardiac disease in patients with dermatomyositis who are not symptomatic. There are subtypes of myositis patients where cardiac involvement is more common (such as those with antimitochondrial antibodies and anti-SRP antibodies), and there it may make sense to keep a c...
