How long would you recommend that a patient continues guselkumab prior to deciding that the therapy is not effective?
Many trials have a placebo-controlled period of 12-24 weeks. Thereafter, all patients receive active treatment. Even if the original treatment allocation remains unknown to the patient and doctor, they know that from that moment on, everyone receives active treatment. This will have an influence on ...
What clinical history or findings make you more concerned for an amyloid-related neuropathy?
Many, including: Presence of a monoclonal IgG or IgA protein on serum or urine protein immunofixation, especially lambda light chain, and especially if kappa to lambda light chain ratio is very low. Unexplained autonomic dysfunction, especially orthostatic hypotension without compensatory tachycard...
Are there adverse consequences of suppressing serum urate levels too much?
It's an interesting question. I personally do not have a lower limit that I have in mind per se, and frankly rarely see anything less than 3 in any of my patients. But I would consider 2-3 being a range which could be deemed low and potentially an issue long term in brain health and because of its n...
Do you recommend that a patient with pre-existing rheumatoid arthritis who requires immune checkpoint inhibitor therapy for a new cancer diagnosis continue their existing DMARD or biologic therapy during ICI treatment?
Excellent question. The initial ICI trials excluded patients with pre-existing autoimmune disease, so most of the data we currently have are from retrospective data series. The current data suggest that RA is a risk factor for ICI-inflammatory arthritis flares. In fact, one study (McCarter et al., P...
How has the ADVISE trial changed your approach to steroid sparing agents for non-infectious uveitis?
The ADVISE trial was a well-designed, multinational trial that compared adalimumab therapy for non-infectious intermediate, posterior, or panuveitis versus conventional immunosuppressive therapy or CID. Two hundred twenty-seven subjects were enrolled over four years, and a fifth year was required to...
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...
What is the most appropriate next step in management for a patient with dermatomyositis who is maintained on methotrexate 25 mg weekly but develops disease flare when prednisone is tapered below 10 mg daily and is unable to receive IVIG?
The fact that the patient cannot taper prednisone below 10 mg indicates that methotrexate alone, while has some effect, is not sufficient to control the disease. There are several options, depending on the severity of each organ involvement. Since the joints are affected, I would favor an agent that...
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...
Is it ever safe to use a biologic DMARD in a patient with RA who is on suppressive antibiotics due to a history of septic prosthetic arthritis?
I have used Orencia and HCQ as more immunomodulating with suppressive M/W/F antibiotics in a patient with UTI/Bactrim.
How do you approach hypogammaglobulinemia monitoring when using obinutuzumab for refractory nonrenal SLE patients?
I would start with a baseline evaluation that includes quantitative IgG levels, HBV serologies, including HBsAg and anti-HBc, to assess reactivation risk even if HBsAg-negative, and a CBC with differential. Before treatment, I would make sure all non-live vaccines are completed, and I would avoid li...
