Do you provide empiric doxycycline for Lyme Disease to asymptomatic patients after a tick bite who haven't developed Erythema migrans or are not sure it was an Ixodes tick?
I would base post-exposure prophylaxis upon local prevalence (unless the patient has a recent notable travel history). For example, Lyme disease is very rare in California due to the Ixodes tick's intermediate host being the Western Fence Lizard (long story short, something in their blood kills the ...
How do you approach evaluation of a patient referred for mononeuritis multiplex and +SSB?
Step 1: A clinical syndrome of mononeuropathy multiplex always requires an EMG study. Is the primary mechanism of the MnM axonal or demyelinating? If it is demyelinating, there are only two possible diagnoses: multifocal CIDP (Lewis Sumner syndrome, which can occur in the context of Sjogren's syndro...
Before re-challenging a patient with ICI after grade 1-2 pneumonitis, do you re-image to confirm resolution of pneumonitis?
Grade 1 pneumonitis is defined as confined to one lobe of the lung or <25% of the total lung parenchyma, while grade 2 pneumonitis is defined as involving more than one lobe of the lung or 25-50% of the lung parenchyma. Grade 1 pneumonitis is typically an incidental finding on CT in an asymptomatic ...
Do you screen for interstitial lung disease in patients with newly diagnosed polymyositis or dermatomyositis in the absence of respiratory symptoms?
I do screen all newly diagnosed IIM patients with PFTs and chest CT. This has a double purpose: establishing a baseline of lung function and, screening for lung cancer. While the patient might not have lung symptoms on presentation, respiratory involvement can manifest later on the course of the d...
Would you favor the use of denosumab over bisphosphonate therapy for treatment of osteoporosis in patients who are at high risk for osteoarthritis given recent data suggesting reduced risk of developing knee OA?
Although the overall data to date concerning the impact of denosumab to reduce incident knee OA or lessen established disease remain limited, there are sufficient signals that warrant further investigation and support the need for an appropriately powered RCT with endpoints that include both patient...
How should the results of the ADVOCATE trial be applied in AAV patients who receive rituximab induction and maintenance therapy?
The following answer was jointly drafted by Dr. Peter Merkel and Dr. David Jayne:The data from ADVOCATE indicate that patients with granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) treated with avacopan 30 mg twice daily and prednisone placebo were able to achieve remission w...
How often are you performing CT screening in CVID patients to screen for ILD?
CT once every 1-2 years, depending on symptoms and PFTs. PFTs, including DLCO, are annually performed.
Is there a period of time after which you would not resume ICI after a patient has had an irAE and required a prolonged steroid taper?
Typically if a patient has required treatment with steroids for four to six months, it was because their irAE was significant (grade 2-4) and refractory to initial treatment. If the patient received combination immunotherapy, such as anti-CTLA-4 and anti-PD-1 agents, one could consider resuming the ...
How do you weigh the risks of re-treatment with infliximab in a patient who has been off it for over a year?
To answer this question, we first need to go back in time. Treatment with infliximab has been known to elicit the formation of antibodies against infliximab. The presence of these antibodies has been associated with infusion reactions in 7-19 % of patients and may also shorten the duration of the ef...
In light of promising results of hydroxychloroquine in COVID-19, should we consider using it prophylactically in cancer patients, especially if immunocompromised?
At this time, as there is no good evidence available, I would not recommend the use of hydroxycholoroquine prophylactically in cancer patients. It is unclear whether it would prevent contagion, probably not, and we still don't know if it will have any effect on the course of COVID-19. We expect ther...
