What recommendations do you provide patients regarding immunization or boosters prior to initiating rituximab?
To my knowledge, there is no unified recommendation, although the majority of us recommend all age-appropriate immunizations plus strong consideration of younger-than-standard-age immunization for diseases such as pneumococcus and VZV prior to initiation of rituximab when medically feasible. Timing ...
Do you recommend allopurinol desensitization in gout patients who develop a rash on allopurinol therapy?
I don't recommend desensitization for allopurinol-allergic patients. There was a time when this made sense due to the lack of a viable alternative therapy. The process is cumbersome in a private practice setting and not as simple as providing the patient with a prescription for febuxostat.Febuxostat...
What strategies have you found most helpful to improve adherence to hydroxychloroquine among patients with lupus?
Great question. This is something I think about a lot. I don't have the perfect answer, but here's how I'm currently approaching it: Reviewing the importance of HCQ at every visit, in patient-friendly terms. I make it clear why they are on the medicine and what it does for them. I say, "This is the ...
Do you check mycophenolate levels in patients prescribed mycophenolate who present with a lupus nephritis flare?
In general, I tend to shoot for an induction dose (3 grams) if I am using Cellcept with steroids for a flare, unless I am doing multitarget therapy or there are side effects such as GI symptoms or cytopenias. In those cases, I lower the dose to 2 grams (1000 mg BID). If there is concern for unsatisf...
What is your approach to a patient with RF+/CCP+ rheumatoid arthritis that was previously on TNFi now with high-titer ANA and dsDNA (crithida 1:2560), +chromatin, +histone?
This scenario reads like TNF inhibitor drug-induced serological lupus. The first clinical issue is: are there accompanying symptoms or signs of systemic lupus erythematosus (SLE) beyond the underlying inflammatory arthritis, which would be better attributed to the seropositive rheumatoid arthritis (...
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 ...
In what clinical situations do you consider azathioprine for treatment of inflammatory arthritis?
Azathioprine (AZA) is among the oldest pharmacologic immunosuppressive agents in use today. Initially developed as a long-lived prodrug of 6-mercaptopurine (6-MP), it was quickly found to have a more favorable therapeutic index. Gertrude B. Elion (Winner of 1988 Nobel Prize in Medicine for “importa...
In patients without Raynaud’s, how frequently do you perform nailfold examination during the initial clinical assessment?
Doing a simple bedside nailfold examination (inspection with the naked eye, otoscope/dermatoscope) is important to do at least once, as part of the general physical examination on all patients, irrespective of Raynaud’s. It might not add value or need to be repeated routinely in patients without Ray...
What is the clinical significance of elevated serum complement (C3 and/or C4) levels?
I have always considered elevated complement levels to be an acute phase reaction and an indication of inflammation, be it infection or cancer, similar to the ESR and CRP. Recent data have linked these elevated levels with obesity and metabolic syndrome. We have known for years that levels of C3 and...
When do you consider genetic testing for autoinflammatory diseases in patients with recurrent pericarditis and fever, particularly when symptoms are highly responsive to IL-1 blockade?
Yesterday ;-). About 10% of patients with recurrent pericarditis have genes that may increase their risk of pericarditis. If you're already managing the patient with IL-1 inhibition, I would strongly encourage you to conduct genetic testing. Just my 2 cents...
