When do you consider testing autoimmune antibodies for axonal polyneuropathies without clear etiology?
Dr. @Dr. First Last gave an excellent summary of the clinical red flags that should trigger antibody testing in polyneuropathies. I would like to highlight that not all antibodies are pathogenic or cause the same phenotypes/clinical syndromes; therefore, I would like to break it down by antibody gro...
What is your approach to refractory oral ulcers in SLE?
Prior to availability of apremilast for psoriatic disease and Behcet disease (which can be effective if a case can be made for the patient accessing this), I found thalidomide to be very effective for this.
What is your approach to management of elevated liver enzymes in patients who recently started treatment with tocilizumab?
This is an important concept because anyone using tocilizumab will eventually wrestle with this question. The question, though, does not tell you whether this is the first time a practitioner sees the liver enzyme elevation, or how high the liver enzymes rose. Since everyone should have had a lipid ...
How do you approach managing nausea and GI side effects when initiating methotrexate?
There are several strategies to minimize nausea and gastrointestinal symptoms with the use of methotrexate. The medication can be taken with food, just not with caffeine. The dose can be split throughout the day it is taken such as half the dose in the morning and the other half in the evening. The ...
How would you approach managing an asymptomatic patient with normal kidney function who has elevated p-ANCA and MPO titers along with evidence for pauci-immune glomerulonephritis on kidney biopsy?
I would assume the patient has hematuria and proteinuria, and that is why they had a kidney biopsy. I would treat this patient with immunosuppression, but would be willing to reduce the dose and duration of immunosuppression depending on the response of the patient. Following the ANCA titer would al...
Which serologic tests are most helpful when evaluating for suspected drug-induced lupus?
If I suspect drug-induced lupus, I typically order the following laboratory testing: ANA/IFA Anti-histone antibody, usually positive in drug-induced lupus Anti-Ro antibody, usually positive in drug-induced subacute cutaneous lupus Anti-dsDNA, usually negative in drug-induced lupus vs positive in id...
Is it necessary to prescribe a steroid taper after two weeks of high-dose prednisone (60 mg daily)?
Interesting question. Not being an endocrinologist, I don't have the expertise to advise but the reference below makes the statement that even short-term steroids can be an issue. I suspect that if you have to stop abruptly from 60 mg daily for 2 weeks, it would probably be fine in most instances bu...
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...
Would you proceed with renal transplant in a patient with lupus nephritis who has progressed to ESRD and is clinically stable, but has persistently elevated dsDNA and low complements despite appropriate doses of hydroxychloroquine and mycophenolate?
Short answer: Yes—if the patient’s clinical lupus is quiescent for at least 6 months, it is reasonable to proceed with kidney transplantation even in the presence of persistent serologic activity (e.g., low complement, elevated anti-dsDNA).Why this matters: Transplant > Dialysis: Patients with LN-ES...
How would you approach the upfront management of a patient with acute unilateral vision loss with strong clinical risk factors for both cardioembolic stroke and GCA if an expedited MRI is not possible due to the presence of an AICD?
I'm definitely not an expert in this topic, but you have many clinical tools to increase/decrease your clinical suspicion for GCA vs. cardioembolic stroke. Some things I would ask: Is this patient currently in Afib? What's their CHADSVASC? Are they anticoagulated? Can we get a TTE to check for vege...
