How would you approach management of a young woman referred for isolated anterior uveitis (now resolved), in the absence of systemic manifestations or end-organ involvement, but with serologies notable for strongly positive PR3 (negative c-ANCA)?
This is a challenging case. While up to 50% of anterior uveitis are idiopathic, and uveitis is relatively uncommon in GPA (<5-10%, episcleritis and scleritis are the most common ocular manifestations. The PR3 antibody is quite specific. Therefore, I would have a high index of suspicion that the uvei...
Do you prescribe hydroxychloroquine to patients who are on other medications that can prolong the QT interval?
First, I'll remind everyone that before COVID-19, case reports of QT-prolongation-associated arrhythmias were rare. It wasn't until COVID that we all at once saw cases with the caveats that these were in patients treated with higher doses of HCQ, commonly loading doses of 800 mg daily, plus COVID-1...
What is the preferred osteoporosis therapy after completing teriparatide in a young woman planning pregnancy within the next year?
It would be helpful to know the T-scores of the spine and femoral neck. I also like to have the bone remodeling markers. My recommendation would be adequate calcium intake of 1000 mg daily, preferably from diet, and 4000 IUs of vitamin D daily, not only to help preserve bone health, but vitamin D al...
In which Sjogren's patients do you prioritize systemic treatment strategies at time of diagnosis?
Answering this question would really depend on what exact type of patient you are dealing with. You may consider initiating oral DMARDs such as hydroxychloroquine, methotrexate, or azathioprine for patients with inflammatory arthropathy or significant autoimmune rashes. More aggressive therapy would...
Are there clinical, laboratory, or imaging features that can help distinguish primary Sjögren’s syndrome from secondary Sjögren’s in patients with overlapping inflammatory arthritis or positive rheumatoid factor?
Such a good query. I don't really know, as associated SjD has been understudied. In my experience, associated Sjogren's does not look that different from Sjogren's alone. We have seen high ocular staining scores and markedly reduced unstimulated salivary flow in associated SjD (SLE, RA). In SjD, the...
In a patient with high +SSA antibodies and distal renal tubular acidosis (RTA), but without sicca symptoms or other systemic features of Sjogren's, should immunomodulatory therapy with hydroxychloroquine or azathioprine be considered in an effort to reduce subclinical tubular inflammation and prevent progression of renal disease?
Renal disease can occur as an initial manifestation in the absence of sicca in SjÓ§gren’s disease (SjD) patients (Goules et al., PMID 31464673). This is important to realize for other systemic manifestations of SjD (e.g., cystic lung disease, tubulointerstitial nephritis, radiographic nephrocalcino...
What are the current recommendations for the management of pediatric non-infectious uveitis?
Usually, by the time children with uveitis come to rheumatology care from ophthalmology, it is chronic in nature. Most of the infectious work-up has been completed. If not, then we will complete before starting systemic therapy. In addition, we screen for rheumatic associations with uveitis (e.g., j...
Do you view the difference between oral and sublingual cyclobenzaprine as clinically significant?
Yes. Oral cyclobenzaprine—a TCA analogue structurally identical to amitriptyline aside from a single double bond—has been used off-label for fibromyalgia for many years. Despite long-standing anecdotal benefit, a prospective placebo-controlled RCT showed only transient improvement at 4 weeks, with n...
How do you determine whether to add abatacept or rituximab to the treatment regimen in patients with mild RA-ILD on methotrexate?
I think of many agents before rituxan for RA ILD: all in various stages of being studied MMF, Orencia/abatacept, Tocli/actemra, and even JAK inhibitors xeljanz/rinvoq. Generally, if I treat and control the joints, the lungs stabilize. 10-20% run independently from joints or extra-articular ILD witho...
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...
