What is in the differential diagnoses for isolated bilateral tarsometatarsal joint erosions in the absence of other clinical or serologic evidence of systemic inflammatory arthritis?
Post-traumatic injury is the most common cause, especially mid-foot sprains and fractures, although not usually bilateral unless there is a predisposition such as high arches and osteoarthritis (OA) that can occur due to mechanical stress. Erosive OA can cause these findings, although more commonly ...
How has the new data regarding long-term follow-up of degenerative meniscal tears vs surgery changed your management approach in these patients?
Degenerative meniscus tears are a common finding on MRI in our older patients. A challenge lies in determining if that finding is the cause of the patient's symptoms. When deciding whether to send for surgical consultation, I query about mechanical symptoms (catching, locking, or giving way) and/or ...
How do you approach incidental NXP-2 antibody positivity in patients without current clinical evidence of myositis or systemic autoimmune disease?
A positive anti-NXP2 antibody in an asymptomatic patient may indicate either a false positive or a subclinical form of dermatomyositis. The initial step is to review the testing method (e.g., ELISA, immunoblot). If possible, confirm the result with a different assay, ideally immunoprecipitation, tho...
What is your approach to a patient with generalized morphea, no systemic involvement but a positive RNA Polymerase III?
I would perform age-appropriate cancer screening given the link between RNA pol III and cancer. Otherwise, I would simply monitor for onset of systemic sclerosis or other autoimmune disease symptoms.
When stopping denosumab and transitioning to PO bisphosphonate, do you wait for 6 months after the last denosumab injection to start PO bisphosphonate?
Some background: In patients discontinuing denosumab without subsequent antiresorptive therapy, BMD rapidly reverts back to baseline with an elevation in vertebral fracture risk (with an enhanced risk of multiple vertebral fractures). Thus, sequential treatment regimens following denosumab have been...
What is your approach to escalating therapies for stiff person syndrome that is refractory to IVIG and steroids?
Step 1: Make sure the diagnosis is correct, especially if seronegative or very weakly positive for GAD65 antibodies.Misdiagnosis of SPS is common and diagnostic criteria have been recently proposed (Reference 1). Patients who complain of subjective stiffness/muscle spasms, but do not have objective ...
Would you favor the use of denosumab over bisphosphonate therapy for treatment of osteoporosis in patients who are at high risk for osteoarthritis given recent data suggesting reduced risk of developing knee OA?
Although the overall data to date concerning the impact of denosumab to reduce incident knee OA or lessen established disease remain limited, there are sufficient signals that warrant further investigation and support the need for an appropriately powered RCT with endpoints that include both patient...
Should the use of avacopan be limited to those patients at increased risk of steroid toxicity given the anticipated high cost of this medication?
Once Avacopan is available for clinical use in the treatment of patients with AAV, providers will need to carefully weigh risks and benefits of the medication while considering other factors including cost.The ADVOCATE trial used a novel glucocorticoid toxicity index that captures common GC-related ...
Do you recommend allopurinol desensitization in gout patients who develop a rash on allopurinol therapy?
I don't recommend desensitization for allopurinol-allergic patients. There was a time when this made sense due to the lack of a viable alternative therapy. The process is cumbersome in a private practice setting and not as simple as providing the patient with a prescription for febuxostat.Febuxostat...
For a patient on appropriate treatment for invasive aspergillosis, how do you determine if and when it is acceptable to reintroduce a TNF inhibitor that likely contributed to their acquisition of the infection but is considered essential for control of their inflammatory condition?
There is no established answer to this question. The reintroduction of a TNF inhibitor must be individualized based on the clinical situation of the patient under consideration. There are two critical questions. First, how much does the patient need the inhibitor”? The more the patient is dependent ...
