This is a difficult question to answer with certainty. Most of the direct data on malignancy risk with JAK inhibitors come from rheumatoid arthritis studies, and primarily involve tofacitinib. It is therefore possible that the risk is not the same across all JAK inhibitors, especially since they dif...

In an SLE patient planning pregnancy whose only clinical manifestation is arthralgia, hydroxychloroquine monotherapy is appropriate. During the pregnant and non-pregnant state, additional immunosuppression is not indicated for a high titer dsDNA; rather, monitoring for organ manifestations is approp...

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 ...

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...

Methotrexate is typically used for irAEs of the musculoskeletal system, such as inflammatory arthritis or myositis. Infliximab tends to be used in the set...

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.

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 ...
