What is the interpretation of two IGRAs with negative mitogen wells, in the absence of immunosuppression?
If I understand this case correctly, the patient is actively ill and the patient's doctors are considering tuberculosis as a possible etiology of the patient's illness. In that scenario, IGRAs and PPDs have a limited to no role. Epidemiology, family history, and other possible exposures do. In your ...
In which subset of patients with concussion do you recommend further brain imaging?
I recommend further imaging of a concussion patient in a subset of patients. If the patient had a seizure with the head injury or any sign of declining mentation within the first few hours, they should have a CT head emergently. If it is within 1 week from injury and they report steadily worsening e...
For patients presenting with ACS and severe aortic stenosis with critical left main disease, would you consider BAV prior to PCI to the left main?
This sounds like a CABG AVR case on the surface; if inoperable or at prohibitive surgical risk, CHIP of the LNA lesion, followed by same setting or elective setting TAVR remains an option. CFA access with a large bore sheath (for CHIP/IABP or IMPELLA) will allow for an easy transition exchange for t...
How do you manage a patient with giant cell arteritis treated with weekly tocilizumab and low dose glucocorticoid who develops sudden vision loss?
Fortunately, this scenario is a rare event, as most patients treated with ongoing tocilizumab (TCZ) and prednisone are at a far lower risk for developing new visual loss due to giant cell arteritis (GCA). A recent paper by Amsler et al., PMID 33752737 reviewing the risk for visual loss in patients b...
How do you manage critically ill poor risk mixed germ cell tumor patients presenting de novo with extensive lung metastases and severe respiratory failure?
A few things. I would make sure the patient gets early brain imaging. I usually talk to the patient and family obviously about the severity of the condition, but also that ICU/intubation/ECMO might be needed over the course of treatment 1. I usually take the 3-day EP approach stop and watch for abou...
Would you recommend switching to DAPT for patients on anticoagulation who develop symptoms of a TIA secondary to ICAD?
It is important to remember that there is more to stroke secondary prevention than antithrombotics. Our use of DAPT in ICAD comes from the SAMMPRIS trial, in which patients in the control group did better than expected compared to historical controls with ICAD in the WASID trial. Recall however, tha...
What is your approach to urate lowering therapy in patient with gout who is on azathioprine (for example, for transplant), where allopurinol and febuxostat are both contraindicated?
This is unfortunately not an uncommon scenario. As mentioned in the question, xanthine oxidase inhibitors such as allopurinol and febuxostat are contraindicated in patients on azathioprine or 6-MP and using them almost always leads to cytopenias due to azathioprine/6-MP toxicity (even in low doses)....
How do you approach the management of patients with suspected membranous lupus nephritis who are found to have positive PLA2R antibodies?
In a patient with known SLE with proteinuria > 500 mg/g and (+) PLA2R antibodies in the serum, a kidney biopsy would be warranted. PLA2R staining should be performed on the kidney biopsy. PLA2R staining must co-localize on the subepithelial aspect in a granular fashion similar to IgG in PLA2R posit...
How would you approach the treatment for patients with renal-limited ANCA vasculitis who have persistent proteinuria, hematuria, and ANCA titers and have completed a steroid taper and received three doses of rituximab?
Renal limited ANCA is usually MPO associated. Isolated PR-3 involvement of the kidneys are rare. Further information is needed in making a decision for this case. We need to know when the patient was diagnosed with ANCA vasculitis. What was the Serum creatinine at presentation? When was the kidney b...
Do you recommend initiating immunosuppression and plasmapheresis in patients with dialysis dependent AKI in the setting of anti-GBM disease who do not have pulmonary involvement?
Anti-GBM disease is a rare disorder (incidence perhaps 1:1,000,000 adults/year) that is characterized as a small vessel vasculitis mediated by anti-GBM antibodies directed against the alpha-3-chain of collagen IV in basement membranes. Perhaps half of patients have disease that involves both the kid...
