Do you reduce the dose of hydroxychloroquine in patients with skin graying if they are not particularly bothered by this side effect?
I wouldn't if they're not bothered, but I would think to look into their HCQ blood levels... we know that certain doses of HCQ are more effective in controlling disease activity than others, and that of course, higher levels may be associated with adverse effects, not just in the skin.
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 ...
How do you approach the frequency of DEXA scan monitoring for older adults on bisphosphonate therapy during the course of therapy?
Depends who you read. ACP: Recommendation 4: ACP recommends against bone density monitoring during the 5-year pharmacologic treatment period for osteoporosis in women. (Grade: weak recommendation; low-quality evidence) [1] Monitoring wasn't addressed in the 2023 update. ACR: For adults continuing...
Does receiving IVIG confound the result of SPEP and/or UPEP?
IVIG being a product of polyclonal immunoglobulins may ‘produce’ a monoclonal spike if the AUC is falsely calculated by the reader. IFE usually shows polyclonal banding but every now and then a monoclonal band is picked up. Being an IgG molecule with a 21 day halflife; and with the assumption that i...
What monitoring would you pursue in a female patient with repeatedly very high titer centromere antibodies but no clinical symptoms of systemic sclerosis or other connective tissue disease?
For an asymptomatic patient with very high–titer anticentromere antibodies (ACA), monitoring should focus on early detection of systemic sclerosis (SSc) and related organ involvement, as higher ACA levels are associated with increased risk of progression. Risk stratification is informed by the devel...
What is your approach to bisphosphonate use in patients with advanced chronic kidney disease and osteoporosis?
I have used serum markers of bone turnover in decision-making for patients with chronic renal disease, both to initiate treatment and to monitor response. This seems to have a basis in the literature (Smout et al., PMID 35703216).This approach has also helped to minimize doses of oral bisphosphonate...
Do you recommend vitamin K2 supplements in patients with osteoporosis?
The answer, as with most vitamin supplementations, cannot be answered with high-level evidence to support a "yes or no". A bit of background and then a brief review of available evidence.Vitamin K is thought to be important for bone health because it activates several proteins involved in bone forma...
How do you decide when to use acid-suppressive medications for GI prophylaxis when patients are on prolonged corticosteroid therapy?
We only use acid-suppressive medications for GI prophylaxis in patients treated with corticosteroids when they have additional risk factors for upper GI bleeding. Risk factors include concomitant NSAID or antiplatelet therapy, history of GI bleeding or peptic ulcer, age over 60 years, prednisone dos...
Do you generally pursue a temporal artery biopsy in a patient who has a halo sign on ultrasound but has an atypical clinical presentation of GCA with normal inflammatory markers in the setting of persistent temporal headache?
This is an important question, and the answer would depend significantly on the details of the presentation. In general, with a highly atypical presentation such as this with normal inflammatory markers AND atypical symptoms, I would pursue TA biopsy and consider large vessel imaging if negative. Wh...
What is your treatment algorithm for management of retroperitoneal fibrosis that does not respond to high-dose glucocorticoids?
There are a number of caveats to this. Is the retroperitoneal fibrosis biopsy-proven and/or IgG4 disease ruled out? If a case is refractory, I first question whether the diagnosis is correct and will often biopsy in this situation with more than an FNA biopsy. The second question is how long have t...
