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...
What would be the clinical role of SGLT-2 inhibitors for lupus nephritis given it has an indication for proteinuria related to CKD?
The benefit for SGLT-2 inhibitors at slowing the progression of kidney disease or death from cardiovascular causes had been well established in patients with diabetic nephropathy. Further studies continued to demonstrate benefit in non-diabetic, proteinuric kidney disease (HR, 0.72 (95% CI, 0.64-0.8...
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 patients with ILD who are started on nerandomilast on top of background nintedanib, what monitoring is most important early in therapy?
I do not use combined therapy often, and I usually stop nintedanib to start nerandomilast. This does depend on how long they've been on nintedanib. If it's within the first three months, lab monitoring as required for nintedanib is important. Otherwise, it's really just side effects. Obviously, from...
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...
