Treatment of Sjögren Syndrome with Glomerulonephritis in Active Systemic Disease
Clinical Scenario
This protocol addresses Sjögren syndrome with renal involvement in the form of glomerulonephritis — specifically membranous glomerulonephritis, mesangial nephropathy, or focal segmental glomerulosclerosis — occurring in a non-cryoglobulinemic context with active systemic disease.
Why This Presentation Matters
Systemic Sjögren syndrome with glomerulonephritis carries a risk of serious renal sequelae, including rapidly progressive glomerulonephritis and renal failure. Treatment of systemic disease must be tailored to organ-specific severity using established disease activity definitions.
Treatment Approach
Management centres on glucocorticoid therapy. The specific approach is calibrated to the severity of presentation, with distinct strategies for moderate versus severe renal disease.
The complete regimen — including sequencing, intensity, and duration guidance — is available in the full protocol below.
Treatment Goal
The primary therapeutic target is a reduction of ≥3 points in the global ESSDAI (EULAR Sjögren's Syndrome Disease Activity Index) score, reflecting a clinically meaningful decrease in systemic disease activity.

- Renal failure; rapidly-progressive glomerulonephritis; hypokalaemic paralysis.
- GCs should be used at the minimum dose and length of time necessary to control active systemic disease, administering pulses of methylprednisolone followed by doses of 0.5 mg/kg/d or lower as induction therapy in severe presentations, and doses <0.5 mg/kg/d in moderate/less-severe presentations, with a final target of withdrawing GCs in inactive patients as soon as possible or at least trying to target a maintenance dose of 5 mg/daily or less with the aid of GC-sparing immunosuppressive agents.
- With respect to the definition of the therapeutic response in systemic SjS, the TF recommends using a reduction of ≥3 points in the global ESSDAI score.
