For patients with suspected complement-mediated TMA, are there specific clinical or laboratory parameters that can help guide the decision for starting empirical treatment (e.g., eculizumab) while awaiting the results of complement testing?
I just want to point out that hemolytic microangiopathy (as seen on the peripheral smear by our Hematology colleague) is paramountly important in determining the presence of TMA. Laboratory parameters may be misleading. I have seen even ADAMT13 levels very low in sepsis and DIC process. Therefore lo...
How would you approach initiating belimumab in a patient with serologic evidence of prior hepatitis B infection?
The patient in question is a patient who has serologic evidence of resolved hepatitis B infection. Of note, testing for hepatitis B is not a formal recommendation before starting belimumab. However, it is also important to point out that testing positive for hepatitis B was an exclusion criterion in...
Do you recommend sending an autoimmune work up for patients with recurrent nephrolithiasis and 24 hour urine chemistries consistent with distal renal tubular acidosis?
I do not think there is a "right" answer to this question. First, I would want more evidence of distal renal tubular acidosis than urine chemistries. Specifically, I would do a urinary acidification test. If positive for distal RTA, and there is no other suggestion in the history or physical examina...
What criteria do you use on echocardiogram and PFT to determine who needs further evaluation for CTD-associated pulmonary hypertension?
PFTs are often obtained in patients with systemic sclerosis to evaluate for interstitial lung disease. Low DLCO on PFTs can signify an increased probability of PH, but it is by no means specific. Echocardiograms are readily available, offer additional information about possible causes of PH (e.g. LV...
Do you counsel your patients on the potential decreased effectiveness of oral contraceptives while on Sarilumab?
As someone who focuses on reproductive health, I personally don't counsel on this. From professional drugs interaction resource: "Plasma concentrations of drugs that are CYP450 substrates may decrease following the initiation of interleukin (IL) inhibitors, tumor necrosis factor (TNF) blockers, or i...
What are magic mouthwash alternatives that you would recommend?
Many of our patients will make their own DIY MMW per Phil's My Pharmacist (YouTube) instructions -- uses benzocaine/Cepacol lozenges -- they say it's much more effective than the compounded one from the pharmacy. It is also more economical.If the majority of bothersome mucositis is in the oral cavit...
How would you approach the treatment of checkpoint-inhibitor-mediated temporal arteritis?
Temporal arteritis or GCA is a rare immune related adverse event due to immune checkpoint inhibitor (ICI) therapy. Corticosteroids are the first line treatment, along with holding the ICI. As there have been limited cases, there is not evidence for IVIG in this setting.
How does the presence of nonalcoholic fatty liver disease (NAFLD) impact your choice of csDMARD for RA?
Excellent question and one that comes up often in practice. For the sake of discussion, let's assume hepatitis B and C serologies are negative and there is no suspicion of viral hepatitis. The presence of NAFLD has a direct impact on my choice of csDMARD for RA in this way: if there is significant l...
Are there certain subsets of ANCA vasculitis patients for whom you would consider life long maintenance therapy?
Overall the field is moving towards longer, and sometimes indefinite maintenance therapy. This is because multiple studies have demonstrated that relapse risk increases when maintenance therapy is stopped. I consider indefinite maintenance therapy for the following patients: 1. Frequent relapsers - ...
How would you manage a patient with antiphospholipid syndrome in the setting of severe steroid-refractory thrombocytopenia?
Dr. @Dr. First Last answered the question of severe thrombocytopenia in a patient with APS and an acute thrombotic stroke. I agree with his approach. However, this “between a rock and a hard place” clinical scenario does also appear not infrequently during the chronic management of patients with APS...
