How do you decide between initiating systemic immunotherapy versus local treatment for uveitis with associated HLA-B27 and spondyloarthropathy?
I find that most, but not all, HLA-B27 iritis can be controlled with topical therapies. To do so requires eliminating other causes of inflammation. Many patients have GI inflammation due to gluten and dairy, despite not having classic celiac disease or lactose intolerance. Reducing their intake, mod...
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 often are you repeating screening PFTs in patients with SARDs who have 3 or more years of normal or stable PFTs?
The answer to this question is complex and needs to be tailored to the individual patient’s risk for ILD and the particular SARD.Approximately 30-40% of patients with systemic sclerosis (SSc) will develop ILD, typically within the first 5 years after the first non-Raynaud’s manifestation and rarely ...
What is the most appropriate next step in management for a patient with dermatomyositis who is maintained on methotrexate 25 mg weekly but develops disease flare when prednisone is tapered below 10 mg daily and is unable to receive IVIG?
The fact that the patient cannot taper prednisone below 10 mg indicates that methotrexate alone, while has some effect, is not sufficient to control the disease. There are several options, depending on the severity of each organ involvement. Since the joints are affected, I would favor an agent that...
How do you approach a patient with idiopathic anterior uveitis who has ongoing disease despite adalimumab every two weeks?
This is a style question, I think. I thought it would be useful to note the choice here might depend on testing for anti-adalimumab antibodies as there is some suggestion that changing to once weekly adalimumab in the presence of anti-adalimumab antibodies might not be efficacious. (Ismayilova et al...
How would you treat corneal melt (in the absence of peripheral arthritis) in rheumatoid arthritis?
Corneal melt is a rare, but serious complication of rheumatoid arthritis. It usually occurs in patients who are sero-positive with active joint disease. A viral infection such as herpes simplex could cause a corneal ulcer that would mimic an immune-mediated melt. It is critical to communicate with t...
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...
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 ...
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...
How often do you recommend ophthalmologic screening exams for patients with sarcoidosis?
The American Academy of Ophthalmology has guidelines for routine eye exams for an asymptomatic, healthy individual (not someone with sarcoidosis). These guidelines include a complete, dilated eye exam at age 40, interim exams at the discretion of the patient and one's ophthalmologist, and an exam ev...
