For a patient with suspected post-streptococcal reactive arthritis who does not meet criteria for acute rheumatic fever and has a normal echocardiogram at presentation, do you prescribe 1 year of antibiotic prophylaxis?
This is a loaded question. Post-Streptococcal reactive arthritis (PSRA) plagued me during my fellowship (many moons ago). There is a fine line between PSRA and rheumatic fever (RF). We rarely see RF in the United States anymore. If I'm convinced it is PSRA and not RF (e.g., RF migratory arthritis qu...
What factors do you consider when deciding to treat IgA nephropathy with immunosuppression in a patient with cirrhosis, given the possibility that IgA nephropathy could be secondary to cirrhosis?
Proteinuria is the most important factor here. If there is significant proteinuria (>1 g/d) and no other clear reason for it, I would treat the IgA nephropathy with immunosuppression. Secondary IgA due to cirrhosis is usually not associated with significant proteinuria.
What factors would encourage you to choose abatacept vs tocilizumab in a patient with RA-ILD with a UIP pattern of pulmonary fibrosis?
The available literature on abatacept and tocilizumab in RA-ILD does not provide a definitive answer and hopefully with the general increase in interest in ILD we will have more definitive data in the near future. My review of the current literature suggests that abatacept has a slightly higher perc...
Should the use of avacopan be limited to those patients at increased risk of steroid toxicity given the anticipated high cost of this medication?
Once Avacopan is available for clinical use in the treatment of patients with AAV, providers will need to carefully weigh risks and benefits of the medication while considering other factors including cost.The ADVOCATE trial used a novel glucocorticoid toxicity index that captures common GC-related ...
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...
Do you check mycophenolate levels in patients prescribed mycophenolate who present with a lupus nephritis flare?
In general, I tend to shoot for an induction dose (3 grams) if I am using Cellcept with steroids for a flare, unless I am doing multitarget therapy or there are side effects such as GI symptoms or cytopenias. In those cases, I lower the dose to 2 grams (1000 mg BID). If there is concern for unsatisf...
How would you approach rituximab dosing in a patient with SLE-Myositis overlap with LN Class III, now with worsening UPCR and concern for worsening ILD 4 months post induction and incomplete B-Cell depletion on recent labs?
This is a challenging and concerning situation, as the patient is declining after rituximab. Without knowing which other medications have been tried, I would prioritize medications targeting life-threatening manifestations, i.e., the LN and ILD. In that case, I would start treatment with steroids, m...
Would you consider combining voclosporin and obinutuzumab for pure Class V lupus nephritis?
I agree with @Andras Perl. Changing his regimen is indicated since target proteinuria (<700 mg/day by 1 year) has not been achieved, and renal biopsy shows ongoing active inflammatory class V (very smart to get that biopsy, by the way!).Obinituzumab (OBI) is the better choice than belimumab in patie...
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...
How would you approach a patient with class III and V lupus nephritis, already on HCQ, MMF, voclosporin and losartan, but has continued proteinuria not yet attaining complete renal response?
Few things are more complicated than lupus nephritis, and this question is not answered easily. It depends on hematuria, Cr, proteinuria, C3, C4, dsDNA, and systemic symptoms. So, it depends on what I think is causing the incomplete clinical response. If I believe it is the class V lesion, I would g...
