How would you approach evaluation and management of a patient with chronic arthralgias and bilateral hand weakness who has a positive ANA (1:160) and low-titer anti-SSB positivity, in the setting of otherwise negative ENA panel, normal inflammatory markers, normal complement levels and immunoglobulins, and unrevealing EMG/NCS testing?
The low titer SSB/La antibody would only factor into the consideration of SjD if there were other suggestive features, like documented hypo salivation and/or high ocular staining score, neuropathy, etc. Would learn when they were totally well and what potential triggering events may have occurred. I...
How do you clinically and diagnostically distinguish stiff skin syndrome from scleroderma?
One other disease consideration that one should differentiate is diabetic cheiroarthropathy, or "diabetic stiff hand syndrome." These patients can see decreased extension of the digits (often referred to as "Prayer sign" changes) and thickening of the skin in the digits. This can be present in 50% o...
In patients without Raynaud’s, how frequently do you perform nailfold examination during the initial clinical assessment?
Doing a simple bedside nailfold examination (inspection with the naked eye, otoscope/dermatoscope) is important to do at least once, as part of the general physical examination on all patients, irrespective of Raynaud’s. It might not add value or need to be repeated routinely in patients without Ray...
How would you apprach a SLE patient who is planning pregnancy on hydroxychloroquine with a high titer dsDNA who cannot tolerate azathioprine and whose only symptom is arthralgia?
In an SLE patient planning pregnancy whose only clinical manifestation is arthralgia, hydroxychloroquine monotherapy is appropriate. During the pregnant and non-pregnant state, additional immunosuppression is not indicated for a high titer dsDNA; rather, monitoring for organ manifestations is approp...
How do you interpret treatment response in the DISCOVER-2 Trial when patients were allowed to remain on up to 10mg of prednisone equivalent for disease control while on guselkumab?
If patients were on less than or equal to prednisone 10 mg, they could continue that in the background during the trial, but note that only 20% of patients were on prednisone, a much lower figure than a typical rheumatoid arthritis trial, which is consistent with the point that rheumatologists shy a...
Do you check mycophenolate levels in patients prescribed mycophenolate who present with a lupus nephritis flare?
In general, I tend to shoot for an induction dose (3 grams) if I am using Cellcept with steroids for a flare, unless I am doing multitarget therapy or there are side effects such as GI symptoms or cytopenias. In those cases, I lower the dose to 2 grams (1000 mg BID). If there is concern for unsatisf...
What approaches can we take to initiate therapy and improve survival rates in patients with HLH?
At our institution, we have comprised a multidisciplinary team to help treat these patients. The team or "HLH task force" as we like to call ourselves is comprised of a clinical immunologist, rheumatologist, dermatologist, critical care physician, hepatologist, BMT attending/hematologist, infectious...
Before re-challenging a patient with ICI after grade 1-2 pneumonitis, do you re-image to confirm resolution of pneumonitis?
Grade 1 pneumonitis is defined as confined to one lobe of the lung or <25% of the total lung parenchyma, while grade 2 pneumonitis is defined as involving more than one lobe of the lung or 25-50% of the lung parenchyma. Grade 1 pneumonitis is typically an incidental finding on CT in an asymptomatic ...
How do you manage worsening cutaneous dermatomyositis when muscle disease appears controlled?
The fact that the patient still has an active pruritic rash while tapering steroids suggests that the current regimen isn't fully controlling the disease, and it can affect quality of life. I would consider adjusting immunosuppression, either adding another agent or switching therapies. The specific...
In a patient with biopsy proven statin associated immune-mediated necrotizing myopathy who previously responded well to methotrexate but now presents with recurrent proximal leg weakness and rising CK/aldolase levels after several years of stability, what would be your preferred next-line treatment strategy?
That's an excellent question. I would approach this as a probable disease flare, after excluding potential triggers such as statin re-exposure, including over-the-counter supplements (e.g., "natural" cholesterol-lowering mushroom products that may contain statin-like compounds). In that setting, I w...
