When is it necessary to monitor the QTc interval in patients on hydroxychloroquine?
The answer to this question is not straightforward mainly because there are limited data in this area. Hydroxychloroquine and Chloroquine directly affect cardiac repolarization and are associated with QT prolongation. Given this, there is an argument for getting a baseline ECG for patients initiatin...
What surveillance plan would you recommend for stage IV melanoma patients who achieve a CR or stable PR response with immunotherapy?
If melanoma patients have achieved CR or PR after a year of immunotherapy treatment, I highly recommend participation in this ongoing ECOG cooperative study: EA6192 / PET-Stop Educational Materials - ECOG-ACRIN Cancer Research Group (NCT04462406). The study uses PET scans in combination with contras...
Does calcinosis appear differently in patients with dermatomyositis compared to systemic sclerosis?
Classically, calcinosis in dermatomyositis and scleroderma are different with dermatomyositis having more typical sheet-like calcinosis in the muscles whereas in scleroderma it is more typical on the fingers, extensor surfaces of the forearm, olecranon, knee, and shins. However, many sclerodermas al...
What is your methotrexate initiation strategy in DMARD-naive RA patients?
Best final dose is 20 to 25 mg per week, not 15 mg per week. D Furst
How do you choose between oral and IV cyclophosphamide for the treatment of ANCA-associated vasculitis?
When considering cyclophosphamide for induction in severe AAV, both oral and IV regimens are reasonable routes of administration. In the CYCLOPS trial (DeGroot, Ann Int Med, 2009), oral cyclophosphamide 2mg/kg/d was compared with IV CYC 15mg/kg q 2 weeks for the first three pulses, then every 3 week...
How do you approach patients with ANCA vasculitis who had partial response, but continue to have disease activity on q 6 month maintenance rituximab and remain on steroids?
This question raises some fundamental issues about the management of patients with ANCA-associated vasculitis (as well as other vasculitides or chronic inflammatory disorders), including i) the need to consider the potential contribution of comorbidities to clinical signs or symptoms suggestive of v...
How do you approach breast conserving therapy in a woman who has formed bothersome keloids after prior surgeries?
I have only seen a few patients who developed keloids following breast surgery, whether or not they received radiation therapy. That also is true of individuals who have had keloids on other parts of their body. Hence, this fortunately seems to be a rare event, and I do not think prophylactic steroi...
Is it ever reasonable to switch to a different TNFi as opposed to switching to an agent in a different class in a case of TNFi induced lupus or psoriasis?
This is a very interesting question where the answer continues to evolve. I would also like to answer the question separately. Both Psoriatic skin lesions and lupus or lupus-like conditions can be induced by anti-TNF-alpha therapy. The pathogenesis may involve changes in cytokine balance.Regarding P...
How would you manage a nodal recurrence of cutaneous SCC if the patient is unable to receive surgery for 6-8 weeks?
I’d first consider referring the patient to a center that could perform the operation, as it is standard of care for a patient with resectable cSCC with nodal metastases. At some centers, there may be a clinical trial of neoadjuvant immunotherapy that could be considered. If those options were not...
What is the role for angiography in the workup of digital ischemia?
Digital ischemia is an especially serious complication in patients with rheumatic disease, particularly scleroderma but can also be a feature of lupus, vasculitis (ANCA associated, PAN), antiphospholipid syndrome, and rheumatoid vasculitis, among others.The presence of digital pain with permanent/pe...
