If methotrexate is contraindicated or not tolerated, what systemic treatments do you use for generalized morphea?
I typically reach for mycophenolate as a second-line agent if methotrexate failed or is contraindicated. If the generalized morphea is actively progressing, I will add a steroid taper as a bridge until the DMARD has time to take effect. Whole body UVA1 is also a helpful adjunctive treatment to a DMA...
What is the difference between P155/140 and TIF1-γ antibodies on the ARUP myositis panel?
TIF1g is the name of the protein itself, whereas "p155/140" refers to the IP (immunoprecipitation) finding of 2 distinct bands at 155 kDa (TIF1g) and 140 kDa (TIF1a), indicative of an anti-TIF1g antibody response. Until recently, ARUP (like most commercial laboratories) used immunoblotting, as it is...
Should methotrexate be stopped prior to radiation therapy if a patient has rheumatoid arthritis?
I have not stopped as dose of MTX for RA is low (7.5 mg) and there is data of CMF with RT for breast cancer with higher dose of MTX showing no significant increase in morbidity.
Do you check for JCV before starting belimumab?
No. The John Cunningham virus (JCV) is highly prevalent in adults (around 85% of us), and developing progressive multifocal leukoencephalopathy (PML) is incredibly rare in belimumab (BEL) patients. It would not change my patient management. Even if someone tested negative for JCV prior to starting ...
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...
Can needle EMG or nerve conduction studies cause transient MRI abnormalities, such as apparent inflammation, edema, or enhancement of a nerve, that could be mistaken for neuritis on subsequent imaging?
Yes—needle EMG can create small, transient post-procedure MRI/MR-neurography abnormalities at needle insertion sites, including focal T2/STIR hyperintensity interpreted as edema and occasional small hematoma, which can potentially be mistaken for local pathology if the timing is not recognized. In a...
How do you approach the management of recurrent episcleritis in a patient with RA that is otherwise well-controlled?
The episclera lies on top of the sclera. The majority of patients with episcleritis do not have a systemic disease, although patients with rheumatoid arthritis are more prone to develop episcleritis. Episcleritis must be distinguished from scleritis, which is also associated with rheumatoid arthrit...
How do you approach work up for underlying rheumatologic disease in patients referred for chronic urticaria?
Chronic urticaria (6 weeks or longer) is often a self-limited disorder seemingly idiopathic in etiology. There are certain autoimmune disease more prevalent in patients with chronic urticaria including systemic lupus erythematosus, Sjogren's syndrome, autoimmune thyroid disease, celiac sprue, and rh...
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?
Such a patient with IgA isotype APL antibodies would not meet EULAR – ACR classification criteria for antiphospholipid syndrome. However, there is evidence that IgA anti-Beta 2GP1 can be pathogenic. Therefore, this patient can meet less stringent disease classification and be considered a candidate ...
How do you decide whether to continue hydroxychloroquine in a young patient who develops subretinal neovascularization with no other risk factors?
Hydroxychloroquine (HCQ), an anti-inflammatory and immunomodulatory agent, is used to treat autoimmune diseases (rheumatoid arthritis, lupus, Sjogren’s disease, etc.) and malarial prophylaxis. Vision problems can ensue resulting from these deleterious irreversible effects of HCQ on retina if the cum...
