Do you recommend checking anti-drug antibodies for patients on TNF inhibitors?
This is a very good question with direct clinical practice implications. I do not check or follow anti-drug antibodies when using TNF inhibitors for the treatment of rheumatoid arthritis or psoriatic arthritis. There are reports that suggest, on a group level, that these antibodies, if present, impa...
What findings on routine monitoring PFTs prompt you to pursue HRCT in your patients with SARDs?
That’s an excellent question, and the strategy might vary somewhat by the specific SARD, but in general, in any SARD patient undergoing annual PFTs, the presence of any of these should prompt an HRCT to evaluate for the development of ILD. FVC drop ≥ 10% DLCO drop ≥ 15% Moderate decline in FVC (5-9...
How do you approach screening for ILD in patients with a diagnosis of MCTD given the recommendation discrepancies between the most recent EULAR and ACR/CHEST guidelines?
Another excellent question! While the EULAR guidelines treat MCTD as SSc-equivalent and suggest universal screening, ACR/CHEST guidelines suggest risk-stratified screening with emphasis on symptoms, PFT abnormalities, and high-risk phenotypes.Prevalence of ILD in MCTD can be high, in the range of 30...
How do you approach the management of a patient with psoriasis and chronic anterior uveitis who is unable to take DMARDs and has tried TNF inhibitors and IL-17 inhibitors but has ongoing bilateral anterior uveitis?
Psoriasis is so common that it is possible that this is a chance association, but published studies do support the likelihood that there is a causal association between psoriasis and uveitis and a much stronger association between psoriatic arthritis and uveitis. The choice of therapy depends to a g...
Would you pursue a kidney biopsy in a patient with stable stage 1 AKI, bland urine sediment, and a positive MPO titer without systemic signs of vasculitis?
PR3-ANCA and MPO-ANCA are associated with substantially higher specificities and positive predictive values for ANCA-associated vasculitis (AAV) than the immunofluorescence patterns to which they usually correspond (C-ANCA and P-ANCA, respectively). However, false-positive results remain a concern. ...
How often do you monitor urine protein levels for patients with membranous nephropathy for whom you initiate obinutuzumab?
Most studies of obinutuzumab in membranous nephropathy are retrospective, with remission rates of up to 83%. Would monitor UPCR every 1-3 months and check PLA2R every 3 months. Immunological remission (negative PLA2R) precedes clinical remission (one study with 76% at 3 mo and 80% at 6 mo), and clin...
Would you consider a shorter course of Romosozumab (3 months) followed by maintenance therapy given recent evidence that it is noninferior to 12 months of therapy for treatment of severe osteoporosis?
I read this study with interest. We knew early on that bone formation marker PINP went to baseline after 6-9 months. We also know from the large teriparatide study with fracture data that each additional month of anabolic therapy with PTH conferred an additional 30% reduction in fractures relative t...
How would you approach using the new vagus nerve stimulator for patients with RA?
Vagus nerve stimulation (VNS) may be a consideration for treating those patients with RA who have disease that is either resistant to multiple DMARDs and biological therapies, or where the risk of immune suppression significantly outweighs the potential benefits of our standard approach to managing ...
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 do you approach management of rheumatoid vasculitis (in this era)?
We don't see rheumatoid vasculitis very often nowadays. When our drug options for RA were limited, most patients had smoldering ongoing disease, which predisposed them to the possible development of a rheumatoid arthritis related vasculitis, though even then, cases were uncommon. Nowadays, our abili...
