Is there any value in nonspecific inflammation seen on a salivary gland biopsy for making a clinical diagnosis of Sjogren’s disease in a seronegative patient with sicca symptoms (ie. chronic sialoadenitis with focus score 0)?
Unfortunately, nonspecific inflammation is unhelpful. In patients classified as having Sjogren's, the minor salivary gland biopsy will have a focus score of 0 in about 20% (Sharma et al., PMID 31092717). So you cannot rule out Sjogren's with a negative/non-specific biopsy. To meet the 2016 ACR/EULAR...
If a patient who has tolerated allopurinol for a prolonged period of time is subsequently found to be positive for the HLA-B*58:01 gene, how would you manage urate-lowering therapy thereafter?
There is a strong association between the presence of the HLA-B*58:01 allele and allopurinol-related severe cutaneous adverse reactions (SCAR* - Stevens-Johnson Syndrome, Toxic Epidermal Necrolysis or Severe Hypersensitivity Syndrome). This association was demonstrated in a Taiwanese study by Hung e...
In a patient with persistent symptoms of Lyme arthritis after initial treatment course with oral antibiotics, do you prefer a second course of oral antibiotics or do you frequently offer a course of IV ceftriaxone?
Patients diagnosed with Lyme arthritis should receive a 28-day course of oral antibiotics, preferably doxycycline. If patients achieve at least a partial response, a second course of oral antibiotics may be given. However, in patients with minimal to no response following the initial course of oral ...
Do you have safety concerns when prescribing GLP-1 medications in patients on corticosteroids or immunosuppressive therapy?
I think we need to be particularly careful when co-prescribing with systemic corticosteroids because of the risk of sarcopenia. We know that rapid weight loss is accompanied not only by a loss of fat tissue but also of muscle. Corticosteroids can also have myotoxicity and cause muscle atrophy. I the...
Will you give a trial of tirzepatide in patients with PsA and obesity who have a partial response to bDMARD rather than switching their immunosuppressive regimen?
Yes, we will give a GLP-1RA in selected patients who have an inadequate response to initial bDMARD or tsDMARD therapy. The major barrier is insurance approval.
Would you order a repeat DEXA scan 1 year later for a kidney transplant patient who had an initial DEXA scan within the first 6 months post-transplant showing osteopenia but no history of fractures, and who has been stable on glucocorticoid-free immunosuppressive therapy?
I agree with Dr. @Dr. First Last. Bone metabolism in renal transplant is woefully shy of good data. My opinion is to monitor Vitamin D levels, provide appropriate supplementation, and monitor PTH levels, using cinacalcet as needed. My target level for PTH is 1-2x the upper limit of normal, also base...
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 ...
Where in the sequence of biologics would you consider guselkumab for patients with active psoriatic arthritis despite standard DMARD therapy?
This is an extremely important question and one that is likely to change as new data becomes available. It is important to remember that psoriatic arthritis (PsA) is a complex and heterogeneous disease and a single approach does not work for every patient. Based on the ACR/NPF 2019 PsA treatment gui...
How long would you recommend that a patient continues guselkumab prior to deciding that the therapy is not effective?
Many trials have a placebo-controlled period of 12-24 weeks. Thereafter, all patients receive active treatment. Even if the original treatment allocation remains unknown to the patient and doctor, they know that from that moment on, everyone receives active treatment. This will have an influence on ...
How do you interpret treatment response in the DISCOVER-2 Trial when patients were allowed to remain on up to 10mg of prednisone equivalent for disease control while on guselkumab?
The dependence on the use of systemic glucocorticoids may indeed be a good reason to change treatment. Especially in patients with psoriatic arthritis. So, if patients are unable to stop systemic glucocorticoids and there are still treatment options for the patient, this could be tried. It is diffic...
