How would you approach asymptomatic hepatic sarcoid?
Hepatic involvement in sarcoidosis is very common. In old autopsy series, as many as 70% of unselected cases of sarcoidosis were found to have granulomatous inflammation in the liver. Today, many possible cases are identified incidentally by more advanced diagnostic testing techniques such as PET sc...
Is the efficacy and dose same for subcutaneous vs intravenous IVIGs being used for dermatomyositis?
Thank you for the very interesting question:When considering the best answer, there is a bit of background I think is important to keep in mind. (I'll put my final thoughts about dosing at the end of this background) First and foremost, although IVIG has been used as a de facto treatment for multipl...
Have you been able to safely use other bisphosphonates in patients who developed an allergic reaction (angioedema) to fosamax?
Hypersensitivity with urticaria in someone on alendronate is quite rare. I am not aware of any publications showing another bisphosphonate safely used in this setting. Although there are significant chemical differences between the various oral and IV bisphosphonates, I personally would avoid the en...
Would you consider utilizing a TNF-inhibitor in a patient with RA/SLE overlap who has already tried methotrexate, hydroxychloroquine, and abatacept?
I would not hesitate to use a TNFi in this situation. For my rationale, see a previous post I answered with a similar question that includes the references for my answer: https://www.themednet.org/question/16121. However, as others have answered in this post, alternatives should also be considered.I...
Do you recommend shingles vaccine to all immunosuppressed patients under the age of 50 y.o.?
This is an interesting question. Clearly, patients with autoimmune or immune-mediated diseases because of their immunosuppressed status are at an increased risk of H. zoster, regardless of age. Presently, the recommendations from the CDC, different professional societies, etc., are to immunize patie...
How do you approach evaluation and management of a patient with recurrent monoarticular inflammatory arthritis of unclear etiology?
Routine testing will not identify Lyme disease although the WBC count is higher than usual. If the antibiotic does not target B burgdorferi recurrence might mean inappropriate therapy previously. WBC count WAAAY too high for mere trauma or internal derangement. Anything else to suggest psoriasis? Lo...
What is your approach to transitioning an SLE patient from a pregnancy incompatible regimen to pregnancy compatible regimen?
There are no clear data on how to do this. One study (Fischer-Betz et al., PMID 23382355) transitioned patients by reducing the MMF by 500mg/d dosing every four weeks and then stopping MMFo once the patient is down to MMF 500mg/d and adding azathioprine 2mg/kg. In my clinical practice, I taper faste...
What are some of the biggest challenges you run into when patients transition from pediatric to adult care?
Expectations – the pediatric health care system tends to have more resources readily available to assist patients (e.g., social work, child life, psychology, pharmacy) and appointment times tend to be longer. In the adult world, resources may be less readily available and appointment times shorter....
How would you manage a patient with ANCA associated vasculitis who has recurrent flare including pulmonary hemorrhage, persistent MPO antibody positivity while on maintenance rituximab and avacopan regimen even after induction rituximab therapy?
Probably cyclophosphamide but maybe mycophenolate or azathioprine.
Which ANCA vasculitis patients are better candidates for cyclophosphamide rather than rituximab?
Both can be used for induction in GPA/MPA vasculitis. I would use rituximab (RTX) if the patient has previously been treated with cyclophosphamide (CYC) and developed a relapse/flare and in patients who are young and with fertility concerns. In GPA/MPA, I tend to use RTX most of the time for inducti...
