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...
When do you consider certolizumab for pregnant women with antiphospholipid syndrome with positive lupus anticoagulant?
Certolizumab is a TNF-α antagonist with minimal or no transfer across the placenta. It was evaluated in the phase 2, open-label IMPACT (Improve Pregnancy in APS with Certolizumab Therapy) trial to prevent placenta-mediated adverse outcomes in pregnant patients with antiphospholipid antibody syndrome...
In patients with severe osteoporosis, history of retinal artery occlusion, and hypercalciuria, would you favor PTH analogue therapy or Evenity?
Assuming that PTH and vitamin D are normal, neither. Chlorthalidone is the treatment of choice in this scenario. Chlorthalidone is usually better than HCTZ, as HCTZ often must be given BID, whereas chlorthalidone can be given daily. I have seen very large improvements in BMD with thiazide therapy, o...
How do you approach adjusting insulin pump settings in patients who have received intra-articular corticosteroid injections?
Managing steroid-induced hyperglycemia in patients with diabetes has always been a difficult problem, and guidelines are hard to come by. Glucocorticoids cause increased insulin resistance and an increased need for insulin. The steroid effect on glucose is greater in the post-prandial state than the...
How do you decide when to use acid-suppressive medications for GI prophylaxis when patients are on prolonged corticosteroid therapy?
We only use acid-suppressive medications for GI prophylaxis in patients treated with corticosteroids when they have additional risk factors for upper GI bleeding. Risk factors include concomitant NSAID or antiplatelet therapy, history of GI bleeding or peptic ulcer, age over 60 years, prednisone dos...
How do you approach osteoporosis screening in men?
While osteoporosis is more prevalent in postmenopausal women, it is often under-recognized in men. The risk of mortality after hip fracture is higher in men, and that risk may extend over 10 years after injury. Men who sustain a wrist fracture are more likely to have severe osteoporosis and a higher...
How soon after a fracture would it be safe to start anti-resorptive therapy?
This is an important question. There is no definitive answer, and there have been no clinical or preclinical studies that demonstrate delayed healing in the presence of bisphosphonates. Personally, I favor waiting a few weeks before we start. That also gives us time to do a proper metabolic workup. ...
What are the clinical prompts that lead you to consider deprescribing bisphosphonate therapy in older adults with osteoporosis?
As a Geriatrician, the essence of my practice is to determine, on regular review (reconciliation), whether an older adult’s medication is appropriate to continue or continue at the same dosing on the basis of physiology, pathology, and/or risk modification. We know well today that medications for os...
When do you consider testing autoimmune antibodies for axonal polyneuropathies without clear etiology?
Dr. @Dr. First Last gave an excellent summary of the clinical red flags that should trigger antibody testing in polyneuropathies. I would like to highlight that not all antibodies are pathogenic or cause the same phenotypes/clinical syndromes; therefore, I would like to break it down by antibody gro...
How should the results of the ADVOCATE trial be applied in AAV patients who receive rituximab induction and maintenance therapy?
The following answer was jointly drafted by Dr. Peter Merkel and Dr. David Jayne:The data from ADVOCATE indicate that patients with granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) treated with avacopan 30 mg twice daily and prednisone placebo were able to achieve remission w...
