Sjögren's disease & overlap diseases
Inclusion-body myositis associated with Sjögren’s disease: clinical characteristics and comparison with other Sjögren-associated myositis
Authors' conclusion
IBM can occur in SjD patients, with muscle features reminiscent of classic sporadic IBM characteristics, but mostly affecting women.

Further findings
| Outcome | SjD-other IM |
|---|---|
| SjD-other IM vs SjD-IBMValue is ESSDAI | 11 (IQR 3–30) |
| ESSDAI | 11 [3; 30] |
| Delay SjD diagnosis to myositis onset | 0 [−0.5; 26] |
| CPK >1000 UI/l | 36% |
SjD-other IM vs SjD-IBM
- SjD-other IM significantly younger, more frequent additional extra-glandular disease, higher ESSDAI, shorter delay, more frequent CPK >1000 UI/l, less frequent classic IBM features
