Do you recommend avoidance of occupational/environmental exposures in patients with pulmonary sarcoidosis?
The best assessment of occupational exposures associated with pulmonary sarcoidosis comes from A Case Controlled Etiologic Study of Sarcoidosis (ACESS). This is nicely summarized in a state-of-the-art article that lists occupations and exposures with both positive and negative associations between o...
How would you define failure of anabolic therapy for severe osteoporosis and when would you consider ordering a second round of Evenity or PTH analogue therapy?
“Failure” of any therapy is often in the eyes of the beholder. The most efficient way to determine if there is anabolic activity is to measure a serum PINP (does not need fasting) and, for the PTH anabolic recheck, the PINP 2-3 months later. IF the delta is >10, you can be confident there is more pr...
How often do you see bony erosions in patients with Lyme arthritis?
There are three ways that Lyme disease can result in joint involvement. The most common is diffuse arthralgias (not a true arthritis) associated with the acute infection. This is self-limited and does not harm the joint. The second is an inflammatory arthritis that is similar to other infected joint...
Would you start hydroxychloroquine (or another DMARD) in a mid-20s female patient with positive ANA, SSA, SSB, and dsDNA, whose only clinical manifestation is intermittent parotid gland swelling?
Hmm... I think the better question to ask is, do you code as Sjogren's lupus overlap to get way more medication options? Certainly, HCQ is a reasonable DMARD and a place to start for both diseases. I would code as lupus and Sjogren's to have more options for the future. Hope someone can weigh in on ...
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...
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 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 ...
