Are there particular subsets of AAV patients in which avacopan is more effective?
The following answer was jointly drafted by Dr. Peter Merkel and Dr. David Jayne:Patients in the ADVOCATE trial were stratified at entry according to time of diagnosis (new/relapsing), diagnosis (GPA/MPA), ANCA serotype (PR3/MPO), and background immunosuppressive (cyclophosphamide/rituximab) with re...
Do you check mycophenolate levels in patients prescribed mycophenolate who present with a lupus nephritis flare?
In general, I tend to shoot for an induction dose (3 grams) if I am using Cellcept with steroids for a flare, unless I am doing multitarget therapy or there are side effects such as GI symptoms or cytopenias. In those cases, I lower the dose to 2 grams (1000 mg BID). If there is concern for unsatisf...
How do you counsel patients with osteoporosis and cervical spine osteoarthritis who are considering chiropractic cervical manipulation or traction?
I am concerned with the risks of actually causing a fracture or nerve impingement/damage. So, I would recommend against.
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?
While it may seem initially that combining antifibrotics is a bad idea due to side effect profiles, it has, in fact, been done with some success. The INJOURNEY trial combined nintedanib AND perfenidone in patients with IPF, and during the study period (12 weeks), those on combined therapy lost only ...
In patients with inflammatory arthritis (RA, psoriatic arthritis) and a history of MGUS are there any concerns regarding use of biologics?
There is no absolute contraindication to any particular biologic used to manage active RA in a patient with MGUS. The literature does point out a small potential risk associated with tocilizumab in terms of development of myeloma influenced by the IL-6 pathway (and I would tend to extend that potent...
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...
How do you decide when to use acid-suppressive medications for GI prophylaxis when patients are on prolonged corticosteroid therapy?
We only use acid-suppressive medications for GI prophylaxis in patients treated with corticosteroids when they have additional risk factors for upper GI bleeding. Risk factors include concomitant NSAID or antiplatelet therapy, history of GI bleeding or peptic ulcer, age over 60 years, prednisone dos...
How do you approach decision-making around initiation of osteoporosis therapy in patients with advanced dementia?
Great question, there are many things that I consider. First, I limit consideration of osteoporosis therapy to patients who have a life expectancy of 1 year or more. This is because the time to benefit from a bisphosphonate is estimated to be about 12 months (Deardorff et al., PMID 34807231). Assumi...
When stopping denosumab and transitioning to PO bisphosphonate, do you wait for 6 months after the last denosumab injection to start PO bisphosphonate?
Some background: In patients discontinuing denosumab without subsequent antiresorptive therapy, BMD rapidly reverts back to baseline with an elevation in vertebral fracture risk (with an enhanced risk of multiple vertebral fractures). Thus, sequential treatment regimens following denosumab have been...
