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 do you counsel patients with dermatomyositis on sun protection?
We make sure patients know that sun exposure can trigger flares, so we strongly recommend staying out of direct sunlight between 10 AM and 4 PM, using broad spectrum, SPF30+ sunscreen daily even when indoors (as UVA can penetrate through windows), and wearing sun protective clothing (ideally UPF-rat...
In patients with SLE do you have concerns about using trimethoprim-sulfamethoxazole (Bactrim) because of a potential risk of lupus flare?
I agree with Dr. @Dr. First Last . I have had too many SLE patients over the years show up in my office with a severe flare from TMP/SMX. We have too many alternative antibiotics these days, including for PJP prophylaxis, so sulfonamide antibiotics should be avoided in SLE patients. The typical scen...
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 approach a patient with idiopathic anterior uveitis who has ongoing disease despite adalimumab every two weeks?
This is a style question, I think. I thought it would be useful to note the choice here might depend on testing for anti-adalimumab antibodies as there is some suggestion that changing to once weekly adalimumab in the presence of anti-adalimumab antibodies might not be efficacious. (Ismayilova et al...
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...
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...
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 counsel patients on the risks and benefits of strontium supplements for osteoporosis management?
No experts whom I know prescribe Strontium for osteoporosis. It has not been shown to be efficacious to reduce fractures, although bone density will rise substantially. Also, bear in mind of very serious toxicities that have been associated with this drug. I would never use it in any of my patients....
What is the role of inebilizumab in the maintenance treatment of IgG4-related disease?
Inebilizumab may play an important role in the maintenance treatment of IgG4-related disease (IgG4-RD), particularly in patients at high risk for relapse. These are typically patients with multi-organ involvement and elevated serum IgG4 levels who initially respond well to corticosteroids but tend t...
