How do you evaluate and manage patients with lupus who are having issues with decreased libido?
Decreased libido is one of several factors contributing to sexual dysfunction for people with lupus and other rheumatology disorders. Although sexual dysfunction is common in our patients, it is rarely discussed during office visits. The first step towards evaluation and management of decreased libi...
What steroid regimen do you typically use for induction therapy in patients with lupus nephritis?
LN initial treatment requires at least three choices: First, initial steroids as pulse methylprednisolone vs. high-dose oral prednisone (e.g., 1 mg/kg/day). Second, if selecting pulse steroids, follow with 1 mg/kg vs. 0.5 mg/kg. And third, double vs. triple immunosuppression from the outset.LN treat...
Do you favor obinutuzumab over voclosporin for patients with lupus nephritis and significant proteinuria and a history of non-adherence to medications?
Non-adherence to medications is a common issue in lupus patients, but this can be even more of a concern in lupus nephritis, where the pill burden for patients can be so high. I usually prefer to use intravenous medications for patients who have had difficulty adhering to oral medications in the pas...
Assuming lab accuracy, what are some of the hallmarks and symptoms that would lead to a diagnosis of ANA-negative lupus as opposed to any other autoimmune condition?
I would not make an initial diagnosis of ANA-negative systemic lupus erythematosus (SLE) lightly, especially since there are so many mimics of SLE. However, it does occur, even in early, untreated patients. Even some of the best lupus centers in the world (SLICC) have a 6% prevalence of ANA-negative...
What dose of methotrexate do you typically continue to prevent antibody formation when adding infliximab for sarcoidosis?
Infliximab is a chimeric molecule that contains approximately 25% murine protein, so it can be immunogenic in some individuals.Development of anti-infliximab antibodies (ATI) has been reported in various autoimmune diseases treated with infliximab.Around 10 to 50% of individuals with rheumatoid arth...
How often are you performing CT screening in CVID patients to screen for ILD?
CT once every 1-2 years, depending on symptoms and PFTs. PFTs, including DLCO, are annually performed.
How long after initiation of steroids and immunosuppressive therapy does muscle biopsy remain reliably informative in the setting of suspected inflammatory myopathy?
I don't think there is any definitive, well-validated answer here. Certainly, obtaining a biopsy within ~2 weeks of initiating therapy, in my experience, has clearly not affected the histopathologic findings that would be characteristic of dermatomyositis, necrotizing myopathy, or autoantibody-assoc...
What would be your differential for a wrist monoarthritis in an elderly female with erosions on MRI after less than 3 months of symptoms?
I would put CPPD arthritis high on the differential, as the wrist is a common site for CPPD arthropathy in the elderly. In the right context, septic arthritis is a possibility, particularly if the patient is immunosuppressed. Indolent infections such as fungal or mycobacterial are possibilities. Les...
If methotrexate is contraindicated or not tolerated, what systemic treatments do you use for generalized morphea?
I typically reach for mycophenolate as a second-line agent if methotrexate failed or is contraindicated. If the generalized morphea is actively progressing, I will add a steroid taper as a bridge until the DMARD has time to take effect. Whole body UVA1 is also a helpful adjunctive treatment to a DMA...
Should methotrexate be stopped prior to radiation therapy if a patient has rheumatoid arthritis?
I have not stopped as dose of MTX for RA is low (7.5 mg) and there is data of CMF with RT for breast cancer with higher dose of MTX showing no significant increase in morbidity.
