A 2026 pictorial review of the conditions that mimic sacroiliitis on SIJ MRI — bone marrow oedema is sensitive but the least specific sign, and overcalling it risks committing patients to lifelong biologic therapy. Erosion, lesion combinations, topographic location, semi-axial imaging and clinical context are the defences against false-positive reads.
A 2026 narrative review of fertility, pregnancy and lactation in SLE — the bidirectional disease–pregnancy relationship, the immunobiology of placental injury, and contemporary peri-conception, pregnancy and lactation care anchored to BSR, EULAR and ACR guidance, including a drug-by-drug safety framework.
Work through a previously healthy 7-year-old girl with six weeks of progressive bilateral leg pain and a limp — one finding at a time. Twelve multiple-choice checkpoints test how you reshape a broad differential as imaging, labs and, crucially, a dietary history land on a diagnosis that is easy to miss.
A 2026 clinical-pharmacology perspective arguing that biologic treatment failure in obesity is partly a pharmacokinetic problem: weight-driven clearance leaves many patients on fixed-dose subcutaneous biologics systematically underdosed, and dosing strategy should be matched to the weight–clearance relationship.
A 2026 narrative review of the IL-5/eosinophil axis in eosinophilic granulomatosis with polyangiitis (EGPA) and the two approved IL-5 pathway inhibitors — mepolizumab and benralizumab — covering their mechanisms, MIRRA and MANDARA trial evidence, real-world data, guideline positioning, and the remaining unmet needs.
The 2025 EULAR update to the Behçet’s syndrome recommendations moves monoclonal TNF-alpha inhibitors (especially infliximab) to first-line induction and maintenance for eye, vascular and parenchymal-CNS disease, displacing cyclophosphamide and the azathioprine-first strategy, and broadens treatment targets to angiographic and endoscopic remission.
The 2025 EULAR update streamlines RA management to 5 overarching principles and 9 recommendations, abandons post-methotrexate prognostic risk stratification, and keeps JAK inhibitors co-equal with biologics after individual risk assessment.
A 2026 RMD Open narrative review of recombinant zoster vaccine (RZV) in inflammatory rheumatic disease — robust efficacy across IRD cohorts (~95% reduction in HZ recurrence; 54–70% effectiveness in SLE), no meaningful short-term flare signal in RCT data, and a practical drug-by-drug timing framework spanning csDMARDs, biologics, JAK inhibitors and B-cell depletion.
In the TELIGAN phase 3 trial, telitacicept — a dual BAFF/APRIL inhibitor already approved for SLE — reduced 24-hour proteinuria by 55% relative to placebo at 39 weeks in adults with IgA nephropathy, with eGFR remaining stable on treatment while declining on placebo.
This 2026 Nature Reviews Rheumatology paper reframes SLE autoantibody production by contrasting the germinal-centre and extrafollicular B cell pathways — their distinct kinetics, affinity profiles, T cell dependence, and therapeutic vulnerabilities — showing that the inflammatory niche, not intrinsic autoreactivity, determines pathogenic B cell fate.
