Do you routinely pursue cardiac evaluation in children presenting with post-streptococcal reactive arthritis given the diagnostic overlap with acute rheumatic fever?
Yes.
Do you recommend medical therapy for extensive atraumatic osteonecrosis of the femoral head to mitigate pain or prevent femoral head collapse?
This is a good question. Extensive atraumatic ON of the femoral head will probably not respond to any medical therapy; eventually, the patient will need a replacement. However, ON that is from a systemic insult (drugs, alcohol) is often bilateral so if the other hip is less affected or not affected,...
Do you continue methotrexate while starting TNFi therapy in patients with refractory pulmonary sarcoidosis?
No clear data to do this in an EBM fashion in my opinion. I keep the baseline anti-inflammatory agents the same for the initial two doses of infliximab and once they are on regular dosing, I decrease the other agent/s. After steady-state, I would still keep a low dose of prednisone (2.5 or 5 mg dail...
Have you seen microscopic polyangiitis associated with temporal artery involvement?
Temporal artery involvement or large vessel involvement in general can be seen in the anca vasculitides, though it is not common. A published series (Kaymakci et al., PMID 37672018) reported 17 patients with TA involvement in AAV patients. Another study of 101 patients with AAV reported the prevalen...
What is your preferred initial treatment strategy for patient with new diagnosis of seropositive RA who has end-stage renal disease?
My initial response is to make sure that the diagnosis of RA is correct. Onset of arthritis in a patient with end-stage renal disease could be from other causes maybe even related to the renal disease itself such as gout or CPPD. If this is truly RA, then the safest approach for initial management w...
What are your thoughts on using abatacept for RA-associated ILD in a patient undergoing treatment for CLL with zanubrutinib, and how would you assess the potential increased risk of infection in this context?
Zanubrutinib is an inhibitor of Bruton tyrosine kinase which is part of an important signaling pathway for B cells. BTK inhibition prevents B cell activation, proliferation, and survival. It is useful for B cell malignancies such as CLL.I have two concerns about using abatacept and zanubrutinib toge...
How would you manage axial stiffness without pain in an elderly gentleman with a distant history of HLA-B27+ axial and peripheral spondyloarthritis, now with SI joint fusion, no peripheral arthritis, normal inflammatory markers, and no response to TNF inhibition?
Based on the history and lack of response to anti-TNF therapy, I suspect the patient does not currently have active inflammatory disease but likely sequalae of prior damage and degenerative spinal disease as a cause of his stiffness. A trial off of the biologic would help assess if the medication is...
Do you prefer allopurinol or febuxostat for patients with chronic kidney disease who are receiving treatment for asymptomatic hyperuricemia?
Allopurinol. For my Asian and sometimes African American patients, I consider HLA testing to make sure they are not at risk for allopurinol hypersensitivity. In which case, I will prescribe febuxostat. Most often, I find the insurance will not even cover febuxostat unless I have tried allopurinol fi...
How do you time concurrent therapy with rituximab and IVIG?
Rituximab has about the same half-life as regular IgG. If the regular IVIG treatment can be delayed, it will be less likely to increase the catabolism of Rituximab. If the regular IgG is given at 3-4 week intervals, I would give the Rituxan halfway between IVIG doses. Complement is needed for optima...
How do you approach new-onset idiopathic intracranial hypertension (IIH) with someone who has history of systemic lupus erythematosus?
Since there is not a clinical recurrence of lupus, let's assume the disease is quiescent. The patient may have a clotting tendency so extra care should be taken in MRV interpretation. Does the MRV show the smooth-walled flow-related stenoses of intracranial hypertension or is it more consistent with...
