How do you weigh the risks and benefits of GLP-1 RAs in patients over age 65 specifically in regards to loss of muscle mass and osteoporosis?
This is indeed a crucial question: rapid weight loss is accompanied not only by a loss of adipose tissue but also by a loss of lean mass, including muscle and bone tissue. This must therefore be taken into account when making decisions, particularly in patients with osteoporosis, frailty, sarcopenic...
How does an incidental finding of low bone density on imaging done for another reason inform your screening approach for osteoporosis?
In patients with CKD, I would also look for changes on the plan radiographs of secondary hyperparathyroidism. For example, erosion of the distal tufts of the phalanges on hand films, erosion of the clavicle, and arterial calcification. If these findings are present, then it signifies hyperparathyroi...
How do you incorporate hyperbaric oxygen therapy into the care of patients with wounds related to ischemic ulcerations?
Hyperbaric oxygen therapy (HBOT) is intended to improve local tissue hypoxia in non-healing ulcers. Evidence for its use remains limited, primarily consisting of case reports and small case series. Most documented cases involve lower-extremity ulcers, often related to macrovascular disease. For digi...
How often do you perform nailfold capillaroscopy in your clinical practice in patients with CTD?
In an ideal world, I would perform nailfold cap on all patients (to gain prognostic information on the extent of disease progression), but this is not feasible, and nailfold cap is not always necessary from a diagnostic perspective if the diagnosis is already clear. It is most useful when the diagno...
How do you approach the diagnostic evaluation of osteoporosis in CKD when renal dysfunction limits use of certain tests or biomarkers?
DEXA is still appropriate, and if anything, would underestimate the actual bone loss. For serum biomarkers, only TRAP5B, bone-specific Alkaline phosphatase (BSAP), and PINP are not altered with renal impairment (i.e., not partially cleared by the kidneys, leading to circulating fragments that render...
What is the maximum dose (mg/kg) you will push an IV TNFi to for a patient with Takayasu arteritis who is adherent and does not have evidence of anti-drug antibodies before switching to an alternate class of therapy?
For uveitis, I have used infliximab at 20 mg/kg/dose every 2 weeks to save vision.
Is Evenity appropriate for a patient with severe osteoporosis (T-score -3.1) unresponsive to bisphosphonates and persistent primary hyperparathyroidism despite two surgeries?
Before, I would institute therapy, I would like to know what the situation is with the primary hyperparathyroidism. Is this primary or FHH? Although a 24-hour urine calcium creatinine ratio is no longer helpful, I find that the serum phosphate and 1,25-dihydroxyvitamin D, along with 25-hydroxyvitami...
Would you consider anabolic osteoporosis therapy in a young adult male with multiple non-traumatic vertebral compression fractures and low bone density for age (Z-score -2.6)?
I think a young male with multiple minimal trauma vert fractures and low BMD is appropriate to consider anabolic therapy. Of course, a thorough workup needs to be done to determine if there are any treatable causes of bone loss. If it is determined that he has “idiopathic osteoporosis” then treatmen...
How do you manage rheumatoid arthritis that flares when an adjunctive NSAID is withdrawn despite otherwise stable DMARD therapy?
I believe one of the critical questions here is the nature of the flare. Is this an individual who went from complete control to 6 new swollen and tender joints and very prolonged morning stiffness? Or is it someone who still visibly lacks evidence of active inflammatory arthritis, continues to have...
Would you add a DMARD such as methotrexate for a patient with GCA and partial response to tocilizumab but inability to taper prednisone below 10mg daily?
This is a clinical scenario that comes up relatively frequently, but unfortunately, there is a lack of data to guide this decision, and both approaches are reasonable. On balance, methotrexate has been demonstrated to have a moderate effect with respect to steroid sparing and reducing relapses in GC...
