How do you approach evaluation and management of a patient with recurrent monoarticular inflammatory arthritis of unclear etiology?
Routine testing will not identify Lyme disease, although the WBC count is higher than usual. If the antibiotic does not target B. burgdorferi, recurrence might mean inappropriate therapy previously. WBC count is WAAAY too high for mere trauma or internal derangement. Anything else to suggest psorias...
How do you explain the concept of CAR-T therapy and why it may work to patients with autoimmune disease who are interested in pursuing a clinical trial?
In full transparency, I have not personally obtained informed consent from a patient immediately before CAR-T or a related cellular therapy. My center has a highly active immune therapeutics program, however, and I have spoken and written extensively about this area. I also serve on our health syste...
How do you optimize retinopathy screening schedules for patients on hydroxychloroquine while also prioritizing cost-effectiveness?
I'll approach this from the cost-effectiveness standpoint as I agree with Drs. @Dr. First Last and @Dr. First Last on their excellent points.Patients with SLE have remarkably high costs when you add up copays, medications, imaging studies, travel, missing work, etc. Anything we can do to help reduce...
Under what circumstances would you consider low-dose radiation therapy for osteoarthritis in an older adult patient?
Here is a recent expert consensus by Joel Block on the use of low-dose radiation therapy in OA: Some highlights: "Placebo-controlled randomized clinical trials have now been reported using LDRT for OA of the knees and of the hands. Taken together, they do not show benefit beyond placebo... While a d...
Can you use leflunomide and rituximab in a patient with both multiple sclerosis and rheumatoid arthritis?
It is rare for a patient to have both diseases, but immunosuppressive therapy can be used for the management of both conditions. A study published in 2021 investigated the use of a combination of rituximab and leflunomide in rheumatoid arthritis (Behrens et al., PMID 33738492). Rituximab has previou...
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?
The dependence on the use of systemic glucocorticoids may indeed be a good reason to change treatment. Especially in patients with psoriatic arthritis. So, if patients are unable to stop systemic glucocorticoids and there are still treatment options for the patient, this could be tried. It is diffic...
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 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...
When do you consider testing autoimmune antibodies for axonal polyneuropathies without clear etiology?
Dr. @Dr. First Last gave an excellent summary of the clinical red flags that should trigger antibody testing in polyneuropathies. I would like to highlight that not all antibodies are pathogenic or cause the same phenotypes/clinical syndromes; therefore, I would like to break it down by antibody gro...
Is cellular therapy for autoimmune disease realistically scalable as a mainstream treatment, or is it more likely to remain reserved for a narrow, most-severe subset of patients?
The answer is that this remains very much a work in progress. Before we can meaningfully address scalability, we need greater certainty about several things: the magnitude and durability of clinical benefit; whether patients can remain drug-free or will require concomitant therapy after treatment; a...
