Do you start bisphosphonates after tapering off menopausal hormone therapy to prevent the rapid decline of bone mineral density?
Women lose one T-score unit (10-12%) of bone mass on average during menopause. Estrogen, as a part of menopausal hormone therapy (MHT), is approved by the FDA to prevent osteoporosis, but not for its treatment. Upon MHT discontinuation, women will experience a period of rapid bone loss, for which st...
Do you routinely perform muscle biopsies in patients presenting with the classic symptoms of Inclusion Body Myositis along with positive CN1A antibody?
YES. There are new consensus guidelines from ENMC about the diagnosis of IBM (Lilleker et al., PMID 38522330). They define the clinical presentation of IBM as typical (age >45, progression over >12 months, long finger flexor weakness > deltoid weakness, quadriceps weakness > hip flexors), or atypica...
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...
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...
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...
In patients with osteoporosis at high fracture risk, what factors most influence your decision to prescribe teriparatide versus abaloparatide?
Both abaloparatide and teriparatide are very effective anabolic agents to reduce vertebral and nonvertebral fracture risk in patients with osteoporosis (although clinical trials did not demonstrate reduction of hip fracture risk). The two agents are more similar than different and both induce an an...
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 treatment of suspected CNS vasculitis with a negative work up?
Suspected CNS vasculitis is, simply put, extremely challenging, most often because the diagnosis is difficult to make. Commonly, the diagnosis is suspected based upon non-invasive imaging showing an unusual distribution of infarcts and/or evidence of intracranial arteriopathy (CTA or formal DSA). I ...
Do you recommend checking anti-drug antibodies for patients on TNF inhibitors?
This is a very good question with direct clinical practice implications. I do not check or follow anti-drug antibodies when using TNF inhibitors for the treatment of rheumatoid arthritis or psoriatic arthritis. There are reports that suggest, on a group level, that these antibodies, if present, impa...
How do you approach treatment in a patient with +anti-CCP antibodies, negative RF and no current evidence of active inflammatory arthritis, but progression of NSIP?
In these cases, observing a positive CCP suggests some form of an immunologic or autoimmune driven porcess responsible for the NSIP. The result may justify the use of immunosuppressive therapies, including corticosteroids and other drugs, to treat the lung disease. Anecdotally, the CCP positivity co...
