Are there specific conventional DMARDs and/or biologics that are contraindicated in patients with alpha-gal allergy?
Here is a Q&A from AAAAI (American Academy of Allergy, Asthma and Immunology) addressing this question for etanercept and other monoclonal antibodies that are manufactured in cell lines that glycosylate with alpha-gal. The author concludes, "The risk is not zero, but likely very low".
What are some practical tips for eliciting an accurate history of Raynaud's phenomenon in patients being assessed for CTD?
I use this approach. I first ask patients if they feel generally sensitive to the cold. All patients with Raynaud's should respond yes to this, but this is not specific, as there are many cold-sensitive patients who don't have Raynaud's. I will then ask if their fingers turn any colors in response t...
How do you approach a child with recurrent parotitis who has had negative serum testing for Sjogren's and IgG4 related disease?
Minor salivary gland biopsy is pretty random and subjective; finding >50 lymphocytes per set field is not that specific/helpful. I would think a parotid gland biopsy and extensive work-up (TB, HIV, sarcoid, lymphoma, etc.) is in order.
How do you counsel patients with postural orthostatic tachycardia syndrome (POTS) regarding safe and effective exercise regimens?
It depends on where they're starting from. If they're starting from scratch, I give them two recommendations: first is the Children's Hospital of Philadelphia protocol, and if they live in town, I refer them to our PT facility at Vanderbilt (The Dayani Center) to have our PT folks help them get star...
How frequently do you monitor CT scans, PFTs, and TTEs in patients with ILA or mild ILD?
Typically, I want my patients with ILD to be seen in clinic every 3-4 months, but of course, that depends a great deal on individual circumstances (e.g., disease severity, what we're doing for their disease, etc.). My typical approach is to have my patients perform spiro, DLCO, and 6MWT Q 3-4 months...
How do you counsel patients on use of creatine monohydrate supplementation during a hospitalization for acute rhabdomyolysis from intense physical training?
I was a primary care doctor for the military for a few years. We regularly saw patients presenting with rhabdomyolysis from intense physical training. A standard question for all that present with this is whether supplements are being used. While there isn't a direct linkage to say that the use of c...
Would you consider using transdermal estrogen in a patient with “high risk” APLS patient on warfarin?
Given her clinical diagnosis of high-risk APS, I would first trial nonhormonal therapies or progesterone-only therapies for management of her post-menopausal symptoms. Current ACR guidance recommends against hormone replacement therapy in patients with APS on anticoagulation (Sammaritano et al., PMI...
What is your treatment approach when managing patients with relapsing lupus nephritis who previously achieved remission with mycophenolate and steroids?
Remember that each lupus nephritis (LN) flare is accompanied by permanent loss of nephrons, as much as a third! Each flare increases the risk for poor response (Perez-Arias et al., PMID 36318456). Relapse is not to be taken lightly.I am a big believer in considering combination therapy as initial th...
How do you approach initial steroid dosing in patients with eosinophilic fasciitis?
I usually start with a high dose at 60 mg daily for a few weeks, then add DMARDs like MTX.
In a patient with sicca symptoms and SS-B antibodies only, can a minor salivary gland lip biopsy with lymphoid aggregates, but also scattered areas of acute neutrophilic inflammation be consistent with Sjogren's Disease?
I agree with @Dr. First Last and cannot speculate on the neutrophils.I'd also like to point out that a French study showed that only 1% of isolated anti-SSB patients had Sjogren's disease, SjD (Jardel et al., PMID 28931060); all others had other autoimmune diseases, neoplasia, infection, and solitar...
