When should patients with diabetes mellitus be screened for osteoporosis?
Hip fracture risk is higher in patients with diabetes (T1DM almost 7 times and T2DM 38% higher than controls without diabetes) (Vestergaard, PMID 17068657), and BMD scores underestimate true risk. That has led the ADA to suggest considering treatment for bone densities with T-score <-2.0, rather tha...
Do you recommend patients hold folic acid on the day they take methotrexate?
The proposed mechanism of action (MOA) of methotrexate in rheumatic disease is not from the antimetabolite angle (given its oncologic MOA as a dihydrofolic acid reductase inhibitor), but rather as a potent anti-inflammatory and immunomodulatory medication through the MOA of extracellular adenosine a...
For patients <65 with significant intermittent steroid exposure who otherwise do not have risk factors for osteoporosis, when, if ever, do you recommend considering DEXA screening?
The FRAX guidelines recommend answering "Yes" for glucocorticoid use when a patient has received the equivalent of prednisone ≥5 mg daily for more than 3 months. However, many patients with rheumatoid arthritis have been treated with intermittent courses of corticosteroids over several years, which ...
Were the patients enrolled in the SEAM-RA trial prior methotrexate monotherapy non-responders?
Yes, presumably at one time, most of these patients were methotrexate non-responders because otherwise, it’s unlikely they would have required escalation to TNFi. Clinicians would typically not add TNFi therapy unless the patient had first failed DMARDs (i.e., methotrexate in this case). It is impor...
In light of promising results of hydroxychloroquine in COVID-19, should we consider using it prophylactically in cancer patients, especially if immunocompromised?
At this time, as there is no good evidence available, I would not recommend the use of hydroxycholoroquine prophylactically in cancer patients. It is unclear whether it would prevent contagion, probably not, and we still don't know if it will have any effect on the course of COVID-19. We expect ther...
Should special precautions be taken patients with Ehlers-Danlos syndrome receiving radiation therapy?
Not all EDS is the same. Most commonly, an EDS patient these days is a clinically diagnosed patient with hypermobile joints, possibly stretchy skin, and possibly chronic pain syndrome. That is a very different picture from vascular EDS with a COL3A1 mutation, which is rare and would have the extreme...
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...
How do you utilize tools such as MMT8 in clinical practice when evaluating myositis?
We test hip flexors in every patient as well as the traditional muscles tested in MMT-8. I agree that it is not ideal that MMT-8 does not include these muscles. In fact, we test all large muscle groups - UE and LE as well as the finger flexors and extensors for complete assessment - then extrapolate...
For patients with evidence of prior bilateral uveitis (PS, pupillary membranes, inactive KP, no view posteriorly) who reports no prior symptoms and who has had negative lab work-up, when do you consider repeat work-up and which labs would you repeat?
This is a difficult question to answer succinctly, as so much information is missing to provide a complete response. However, it does raise some important points that are worth mentioning:There is a prevailing tenet, which I was taught as a resident and hear often from residents today, that 1st epis...
In patients with isolated anti-Centromere antibody positivity and Raynaud's phenomenon without other features of systemic sclerosis, what is your approach to screening for pulmonary complications?
In patients with isolated anti-centromere antibody (ACA) positivity and Raynaud's phenomenon, even without overt systemic sclerosis, the primary concern is pulmonary arterial hypertension (PAH), which can develop at any point, including decades after initial presentation. Notably, ACA-positive patie...
