How would you approach immunosuppression in a patient with well-controlled HIV and RF+ rheumatoid arthritis breaking through hydroxychloroquine with ongoing inflammation confirmed on ultrasound?
There is a reasonable amount of literature on this topic. The consensus is that if ongoing HAART therapy is effective at controlling viral load and maintained, Methotrexate and TNF antagonists are well tolerated; they do not seem to affect HIV viral load. The safety of JAK inhibitors, leflunomide, a...
How do you manage patients with scleroderma who present with finger ulcerations without other signs of soft tissue infection and MRI demonstrates potential concern for osteomyelitis?
I think this is a tricky situation. Sometimes there is bone damage from acro-osteolysis from the ischemic injury of the scleroderma itself, which can sometimes be difficult to distinguish from osteomyelitis. I would consider watching closely for other signs of deeper infection. You could also consid...
Would you give a trial of immunosuppression in a patient with previously diagnosed IPF who now comes to you with moderate titer ANA and history of discoid lupus but no other clear systemic features or lab abnormalities suggestive of SLE?
No, I would not automatically RX immunosuppressants in this clinical scenario, which has numerous facets to it that do need to be addressed: The treatment for progressive idiopathic pulmonary fibrosis (IPF) is an antifibrotic, not an immunosuppressant. I ALWAYS manage my SLE-pulmonary patients with ...
How do you approach laboratory evaluation in patients with fatigue?
First search for evidence by history and physical examination for any evidence of inflammation. If there is tailor the lab workup rather than ordering tests as screening tools. ESR and CRP to start with. Anything more without a reasonable a priori likelihood of the targeted diagnosis is just asking ...
What’s your drug of choice for patients with stable antisynthetase NSIP-ILD and overlap RA (CCP+) with significant polyarthritis as main manifestation?
Rituximab
Do you routinely evaluate patients with collagen disorders or Ehlers-Danlos for platelet defects?
Yes, I routinely carry out a full hemostasis evaluation, including platelet aggregation and release studies, in patients referred to me with easy bruising and hypermobility with an increased Beighton score suggesting EDS and in those already diagnosed genetically with EDS. EDS patients typically hav...
Do you routinely consider FDG PET/CT imaging for workup of fever of unknown origin?
The landscape of FUO and IUO and our clinical approach to diagnosing its cause has changed significantly over the past several decades. More sensitive microbiologic screening for infectious etiologies, including syndromic molecular panels and next-generation sequencing are now clinically available a...
Do you recommend patients hold folic acid on the day they take methotrexate?
The proposed mechanism of action (MOA) of methotrexate in rheumatic disease is not from the antimetabolite angle (given its oncologic MOA as a dihydrofolic acid reductase inhibitor), but rather as a potent anti-inflammatory and immunomodulatory medication through the MOA of extracellular adenosine a...
What is your approach to counseling patients on the safety and side-effect profile of a biosimilar compared to its reference biologic?
Relevant question as insurance companies may require a biosimilar over the reference biologic. According to the FDA, the spin-off (my term) must be "highly similar" to the original in both efficacy and safety. Approval is based on review of clinical trial data. As for my approach: until proven other...
In what clinical situations would you favor IM methylprednisolone over a short oral prednisone taper for managing an RA flare?
I am not an RA expert; however, I am well-versed in the use of IM steroids for flares.After Dr. Petri's FLOAT study in SLE (Danowski et al., PMID 16395750), we have utilized IM steroids instead of daily PO prednisone as our "go-to" treatment of choice as much as we can over Medrol dose packs and QD ...
