How would you approach new-onset large vessel vasculitis in a young patient with Crohn's disease?
Patients with Crohn's Disease (or IBD) can develop features of large vessel vasculitis or even other forms of vasculitis. The first consideration in a young patient would be determining the type of vasculitis--whether there is a distribution and clinical picture suggestive of TAK. It is important to...
Do you screen for interstitial lung disease in patients with newly diagnosed polymyositis or dermatomyositis in the absence of respiratory symptoms?
I do screen all newly diagnosed IIM patients with PFTs and chest CT. This has a double purpose: establishing a baseline of lung function and, screening for lung cancer. While the patient might not have lung symptoms on presentation, respiratory involvement can manifest later on the course of the d...
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...
What are the current recommendations for the management of pediatric non-infectious uveitis?
Agree with Dr. @Dr. First Last's answer. By the time these patients see pediatric rheumatology, they have had a number of labs drawn looking for infectious and non-infectious etiologies of uveitis and have also usually been trialed on topical steroid drops (predforte or otherwise) +/- oral prednison...
When using IV TNF inhibitors, do you follow levels to determine if the current dose is adequately treating the patient?
I tend not to get levels, but rather I rely on clinical response; if partial response, often increasing dose (or shorten intervals) can provide dramatic benefit. If the prior response is lost, then consider getting levels and checking for HACAs. I often use TNFi with csDMARDs (e.g., weekly SC methot...
For a pediatric patient with juvenile spondyloarthropathy with partial response, though ongoing axial disease, on a JAKi, would you increase the dose of JAKi, add methotrexate, or switch to alternate therapy like IL-17 inhibition?
Let me first disclose that I am not a pediatric rheumatologist and would defer to one. Have NSAIDs been tried and optimized? If not, that is the best first option. In general, optimizing the dose of a medication that seems to be working is a great choice. However, I do not know what current dosage i...
How do you approach management of a patient presenting with clinical manifestations of systemic sclerosis (cutaneous involvement, Raynaud’s phenomenon, and pulmonary arterial hypertension) but negative serologies?
Systemic sclerosis is a clinical diagnosis, and there are patients who don't demonstrate antibodies on currently available clinical labs. In addition, there are patients with mild phenotypes who may also not meet the current classification criteria. I think if the clinical syndrome is consistent wit...
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.
Do you continue PJP prophylaxis indefinitely in patients on rituximab maintenance therapy?
Risk for PJP infection is usually in the context of moderate-high dose corticosteroid therapy or low T cell counts.
In an infant whose mother resumes TNF inhibitor therapy (e.g., adalimumab, infliximab, certolizumab) after delivery and is breastfeeding, do you recommend delaying live vaccinations?
IgG-based biologic therapies - including TNF inhibitors - are all considered compatible with breastfeeding, since IgG passes only minimally into breast milk. Given these agents are proteins, the minimal drug that is transferred is unlikely to remain intact (or active) with passage through the infant...
