In patients with inflammatory arthritis (RA, psoriatic arthritis) and a history of MGUS are there any concerns regarding use of biologics?
There is no absolute contraindication to any particular biologic used to manage active RA in a patient with MGUS. The literature does point out a small potential risk associated with tocilizumab in terms of development of myeloma influenced by the IL-6 pathway (and I would tend to extend that potent...
What steroid regimen do you typically use for induction therapy in patients with lupus nephritis?
LN initial treatment requires at least three choices: First, initial steroids as pulse methylprednisolone vs. high-dose oral prednisone (e.g., 1 mg/kg/day). Second, if selecting pulse steroids, follow with 1 mg/kg vs. 0.5 mg/kg. And third, double vs. triple immunosuppression from the outset.LN treat...
What findings on routine monitoring PFTs prompt you to pursue HRCT in your patients with SARDs?
That’s an excellent question, and the strategy might vary somewhat by the specific SARD, but in general, in any SARD patient undergoing annual PFTs, the presence of any of these should prompt an HRCT to evaluate for the development of ILD. FVC drop ≥ 10% DLCO drop ≥ 15% Moderate decline in FVC (5-9...
How would you advise a CKD patient who asks about oral NSAIDs for management of chronic pain if they have a contraindication to taking acetaminophen?
This depends on the severity of the CKD/eGFR, age, course of disease, available alternatives to NSAIDs, severity of pain and impact on QoL, frequency with which NSAIDs might be taken. I have advised patients whose QoL is adversely affected by pain to take occasionally if needed but to keep to minimu...
How do you counsel patients with GCA on the benefits of steroids who have already experienced vision loss?
I first tell the patient they are at considerable risk for further visual loss in the same eye or the other eye over the next 1-2 weeks. I also let them know that, even though their risk of visual loss has been reduced, their best option for preventing further visual loss is immediately starting hig...
Is there any indication for IVIG in immunocompromised patients with only decreased IgM and/or IgA levels?
Nope. IVIG preparations contain IgG not IgA or IgM. Low serum IgA may or may not be associated with low IgA levels in mucosal surfaces leading to a risk of local infections. Low levels of one or both may be asymptomatic but in the right setting might suggest a need for evaluation of plasma cell dysc...
For ICI arthritis, how soon do you start DMARDs?
Great question! This is complicated- is it one joint? Inject with steroids! Are there many joints? Is it gout-based, spondyloarthropathy, or more like seronegative RA or PMR-like?Also, where are they in the cancer space? In surveillance but high risk, what type of cancer, etc, etcI start this way: 2...
Do GLP-1 agonists have measurable anti-inflammatory effects in diseases like RA or spondyloarthropathies beyond weight loss?
There is currently no evidence of efficacy in chronic inflammatory arthritis. Due to their mechanism of action, we can hope that they will be effective because of their anti-inflammatory and immunomodulatory properties, which have been well demonstrated in numerous experimental models. But only rand...
Would you start hydroxychloroquine (or another DMARD) in a mid-20s female patient with positive ANA, SSA, SSB, and dsDNA, whose only clinical manifestation is intermittent parotid gland swelling?
Hmm... I think the better question to ask is, do you code as Sjogren's lupus overlap to get way more medication options? Certainly, HCQ is a reasonable DMARD and a place to start for both diseases. I would code as lupus and Sjogren's to have more options for the future. Hope someone can weigh in on ...
How do you approach adding colchicine to a patient who is on a stable statin regimen?
This is a good question and a tough situation, since the drug-drug interaction here can be as subtle as myalgias but as severe as rhabdomyolysis (rare but happens). If you can avoid long-term colchicine in this situation, it is always best. These situations (hypercholesterolemia and crystal arthropa...
