What are the best labs to trend improvement in HLH?
Unfortunately, there is not one specific laboratory test to definitively trend responses to HLH directed therapy. In general, our approach is to obtain baseline inflammatory labs including CBC with differential, ferritin, soluble IL2 receptor (sIL2r), triglycerides, coagulation studies (PT/PTT) incl...
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 is your approach to long-term immunosuppression in patients with Adult Onset Stills Disease?
For persistent or recurring disease flares, IL-1 blockers (canakinumab or anakinra).
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...
How should the results of the ADVOCATE trial be applied in AAV patients who receive rituximab induction and maintenance therapy?
The following answer was jointly drafted by Dr. Peter Merkel and Dr. David Jayne:The data from ADVOCATE indicate that patients with granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) treated with avacopan 30 mg twice daily and prednisone placebo were able to achieve remission w...
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 ...
In the treatment of osteoarthritis with low-dose radiation therapy is there data to support the claim that LDRT does not limit or preclude later orthopedic surgery?
At LDRT doses, the biological effects are anti-inflammatory and immunomodulatory rather than cytotoxic or fibrogenic, and there is no evidence of vascular injury, impaired cellular proliferation, or tissue destruction. Animal models and cellular studies provide robust evidence that LDRT at OA releva...
How do you counsel and manage patients with chronic pain conditions such as fibromyalgia or osteoarthritis who are taking centrally acting agents (gabapentin, duloxetine) and are planning to use or self administer psychedelics for symptom management?
Interesting query since some studies do suggest that psychedelics may be useful in treating chronic pain, and their mechanism of action regarding neuroplasticity is similar to approved centrally acting agents, like duloxetine. I would first review the limited role of medications in chronic pain and ...
Is your approach to managing immune related adverse events altered at all in light of COVID-19?
First of all, I wish to thank @Dr. First Last from Johns Hopkins/Sibley for his advice addressing this critical topic.We are all witnessing a rapidly evolving crisis that none of us have been prepared for and it is the right thing to quickly consider as best as we can how the COVID-19 pandemic shoul...
What is your approach to a patient with undetectable MMR titers checked prior to or during immunosuppression and a history of MMR vaccination in childhood?
MMR titers are good correlates of protection. If any titer is undetectable it could be one of these situations: Primary failure. The components of the MMR have different efficacy. Two doses of appropriately given MMR will have 96+% against measles, but only 88% for mumps. Thus 1 in 10 appropriately...
