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 a patient with biopsy proven statin associated immune-mediated necrotizing myopathy who previously responded well to methotrexate but now presents with recurrent proximal leg weakness and rising CK/aldolase levels after several years of stability, what would be your preferred next-line treatment strategy?
That's an excellent question. I would approach this as a probable disease flare, after excluding potential triggers such as statin re-exposure, including over-the-counter supplements (e.g., "natural" cholesterol-lowering mushroom products that may contain statin-like compounds). In that setting, I w...
What patient factors are most important when considering who needs a broader workup for osteoporosis prior to starting therapy?
A workup to rule out secondary causes must be done prior to starting therapy for osteoporosis. A good history and exam are recommended to look for any clues for modifiable factors. At a minimum, one should do CMP, 25-OH vitamin D, TSH, and a 24-hour urinary calcium or calcium/creatinine ratio should...
In patients treated with infliximab, do rates of immunogenicity vary based on underlying disease (RA, IBD, sarcoidosis, etc) and/or baseline disease activity?
Yes, rates of infliximab immunogenicity appear to vary based on underlying disease, with evidence showing higher rates for RA than IBD and spondyloarthritis, and tend to increase with higher baseline disease activity. Most patients tend to develop anti-drug antibodies within the first year, but this...
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?
If patients were on less than or equal to prednisone 10 mg, they could continue that in the background during the trial, but note that only 20% of patients were on prednisone, a much lower figure than a typical rheumatoid arthritis trial, which is consistent with the point that rheumatologists shy a...
How would you apprach a SLE patient who is planning pregnancy on hydroxychloroquine with a high titer dsDNA who cannot tolerate azathioprine and whose only symptom is arthralgia?
In an SLE patient planning pregnancy whose only clinical manifestation is arthralgia, hydroxychloroquine monotherapy is appropriate. During the pregnant and non-pregnant state, additional immunosuppression is not indicated for a high titer dsDNA; rather, monitoring for organ manifestations is approp...
Would you consider combining voclosporin and obinutuzumab for pure Class V lupus nephritis?
I agree with @Andras Perl. Changing his regimen is indicated since target proteinuria (<700 mg/day by 1 year) has not been achieved, and renal biopsy shows ongoing active inflammatory class V (very smart to get that biopsy, by the way!).Obinituzumab (OBI) is the better choice than belimumab in patie...
Would the need for infliximab/MTX/nonsteroidals to control initial irAE affect your decision to rechallenge these patients with ICI?
Infliximab and methotrexate are generally used in irAE grades 3 or 4, or in grade 2 irAEs that are refractory to initial treatment with steroids. Methotrexate is typically used for irAEs of the musculoskeletal system, such as inflammatory arthritis or myositis. Infliximab tends to be used in the set...
Do you routinely check morning cortisol before discharging a patient who received more than 3 days of high-dose corticosteroids during a hospitalization for an acute illness?
There is not enough detail in the question to provide a clear answer. Usually, suppression of the hypothalamic-pituitary-adrenal (HPA) axis would take more than just a few days. If someone has been on high-dose glucocorticoids for longer (e.g., two weeks), we would usually discharge the patient on a...
Should the use of avacopan be limited to those patients at increased risk of steroid toxicity given the anticipated high cost of this medication?
Once Avacopan is available for clinical use in the treatment of patients with AAV, providers will need to carefully weigh risks and benefits of the medication while considering other factors including cost.The ADVOCATE trial used a novel glucocorticoid toxicity index that captures common GC-related ...
