Is it okay to use COX-2 selective NSAIDs in patients with IBD-associated arthritis when the IBD is in remission?
I do not feel comfortable prescribing COX-2 NSAIDS to patients with IBD in remission. If I have such a patient and an NSAID is the major therapeutic option, I will reach out to the treating gastroenterologist for an opinion on whether this is advisable.
How do you manage patients who are Hepatitis B core antibody positive/surface antigen negative and starting a biologic DMARD (other than rituximab)?
According to the 2015 American College of Rheumatology Guidelines, a patient with natural immunity to Hepatitis B (Core & Surface Antibody-positive; Antigen-negative, normal liver function tests) can be treated as any other patient. However, monitoring of viral load is recommended "regularly" at 6-1...
How do you assess transaminitis in a patient with sarcoidosis with known liver involvement being treated with methotrexate?
This can be fairly tough, as you cannot assess for hepatoxicity from methotrexate in a patient who already has a transaminitis. Hepatic sarcoidosis occurs in 11-80% cases and is often asymptomatic. Some patients may have a transaminitis, elevated alk phos, or liver lesions noted on imaging. Serious ...
Do you avoid any specific biologic therapies in HIV positive patients?
At present, the most safety data on the use of biologics in HIV is TNF inhibitors. CD4 count should be > 200 and VL undetectable. Etanercept is most preferable, give lower incidence of serious infections as well as its efficacy as monotherapy (without methotrexate). Wangsiricharoen et al., PMID 2733...
How do you manage patients on atezolizumab/bevacizumab with advanced HCC who develop arterial thrombosis?
I would stop bevacizumab if there is arterial thrombosis and start anticoagulation, continue single-agent atezolizumab. Would not stop the bevacizumab for portal vein thrombosis as it is most of the time a tumor thrombus.
For patients with HCC receiving atezo/bev, would you advise any other clinical investigations scheduled during treatment other than basic lab monitoring?
In the IMBrave 150 study, the most common serious toxicity in the AB arm was GI bleeding. And everyone was required to have their varices both evaluated and treated. It’s not convenient, but get the EGD before starting treatment!
Is anticoagulation a relative contraindication to atezolizumab/bevacizumab for advanced HCC?
Anticoagulation is considered safe with bevacizumab unless the patient has an increased of bleeding; as such, any varices should have been adequately treated before treatment with atezolizumab/bevacizumab; I would also avoid anticoagulation and atezo/bev concurrently in patients with platelet count ...
Would you hold all immunosuppressive medications for the first month of LTBI treatment, or just biologics?

Would you use an IL-17 inhibitor for a psoriatic arthritis patient with inactive inflammatory bowel disease?
It depends on the options. While I would generally avoid using an IL-17 inhibitor in a patient with a h/o IBD, if there are no other reasonable treatment alternatives, and the IBD has been inactive for a significant period of time (a year?), then I would consider it, after a full discussion of the r...
What is your preferred second line therapy for an HCC patient who progressed after first line checkpoint inhibitor monotherapy?
After progression on immunotherapy monotherapy, assuming the patient is still eligible for further therapy and VEGF inhibition, I will move to a VEGF TKI. While the data supports the use of lenvatinib or sorafenib in the front-line setting (REFLECT and SHARP trials), I will use one of these agents (...
