Is there an association between treatment with anti IL-5 agents for eosinophilic asthma and the development of RA?
Not seen in clinic but would like to know also.
What is your algorithm for transitioning a patient with chronic noninfectious posterior uveitis from corticosteroids to immunosuppressive therapy?
There are some forms of noninfectious posterior/panuveitis where it is known from the time of uveitis diagnosis that steroid-sparing immunosuppression (IMT) will be needed. For example, in birdshot retinochoroiditis or serpiginous choroidopathy, IMT is often initiated in concert with oral corticoste...
Do you always pursue biopsy confirmation before diagnosing IgA vasculitis?
Technically, yes (by definition), but practically, not necessarily: Biopsy for direct immunofluorescence (DIF) testing would be required to confirm the status of IgA in cutaneous vasculitis. However, the presence of lesional IgA correlates positively with the clinical presentation (e.g., Henoch Schö...
Do you seek pathologic confirmation before proceeding with empiric immunosuppressive therapy in symptomatic patients with radiographic NSIP?
In general, getting lung biopsies is needed in a minority of people who have clear evidence of NSIP on HRCT. If there is any evidence to suggest a concomitant ARD, a biopsy will not typically be needed. In our combined ILD-Rheumatology clinic, we see these patients all the time and I can think of on...
Do you consider metformin as a disease-modifying adjunct in the management of patients with OA, particularly in those with comorbid metabolic syndrome or type 2 diabetes?
Based on the Pan et al., PMID 40274279, and the broader literature, I would not yet formally classify metformin as a disease-modifying osteoarthritis drug (DMOAD), but the evidence is increasingly compelling, particularly in the metabolic osteoarthritis (OA) phenotype.This randomized controlled tria...
How do you approach the workup of pauci-immune glomerulonephritis?
When a kidney biopsy reveals a pauci-immune GN, the Ddx must extend well beyond classic AAV and infective endocarditis. For instance, anti-GBM disease should remain high on the list, as up to 25% of these patients present with a "dual-positive" ANCA, and the characteristic linear IgG staining on IF ...
Can you use bisphosphonates in a patient with osteoporosis who has had prior avascular necrosis of TMJ due to steroid use?
Due to the rarity of medication-related osteonecrosis of the jaw (MRONJ) and significantly high fracture risk from osteoporosis, prior history of osteonecrosis is not considered an absolute contraindication for bisphosphonate use. The clinical picture is important in weighing this decision. If the p...
What is your approach to the diagnostic workup of small fiber neuropathy in patients with known rheumatic disease?
Small fiber sensory neuropathy (SFN), in general, including in patients with rheumatic diseases, should be suspected based on symptoms (positive more than negative sensory symptoms) and ideally confirmed by clinical examination showing altered temperature and/or pain/pinprick perception in the limbs...
Does receiving IVIG confound the result of SPEP and/or UPEP?
IVIG being a product of polyclonal immunoglobulins may ‘produce’ a monoclonal spike if the AUC is falsely calculated by the reader. IFE usually shows polyclonal banding but every now and then a monoclonal band is picked up. Being an IgG molecule with a 21 day halflife; and with the assumption that i...
When stopping denosumab and transitioning to PO bisphosphonate, do you wait for 6 months after the last denosumab injection to start PO bisphosphonate?
Some background: In patients discontinuing denosumab without subsequent antiresorptive therapy, BMD rapidly reverts back to baseline with an elevation in vertebral fracture risk (with an enhanced risk of multiple vertebral fractures). Thus, sequential treatment regimens following denosumab have been...
