Lupus & antiphospholipid syndrome
Tubulointerstitial inflammation driving interstitial fibrosis and tubular atrophy predicts poor renal outcome in refractory lupus nephritis
Authors' conclusion
TII predicts the development of IF/TA in LN and independently from glomerulosclerosis is associated with progression to ESKD.
Study context
- Population
- Lupus nephritis (LN) patients with ≥2 biopsies from 1994 to 2018; 84% female, age 25 (+/−12) years at diagnosis; 90% class III or IV proliferative LN with or without class V on initial biopsymedian follow-up 11 (6–16) years
- Participants
- 104 patients
- Outcome
- ESKD and progression of IF/TA
Methodological detailsrepeat kidney biopsies, multiplex immunohistochemistry
- Repeat kidney biopsies
- Multiplex immunohistochemistry
Main finding
As reported in the abstract
Patients developing end-stage kidney disease (ESKD)
47
Persistent tubulointerstitial inflammation (TII) ≥ 25% in the absence of chronicity, only histological predictor of ESKD: OR
4.13 (1.06, 16.06) (95% CI)
Observational data: associations, not effects.
Further findings
TII composition (multiplex immunohistochemistry)
- TII occurred as CD8 T cell-mediated tubulitis or as organized T and B cell rich infiltrates reminiscent of tertiary lymphoid structures
