OBJECTIVES: The presence of tubulointerstitial damage (TID) on renal biopsy is
considered to be a late sequela of lupus nephritis (LN). The objective of this
study was to determine if TID predicts progression to end stage renal disease
(ESRD) in LN patients without advanced kidney disease. METHODS: All SLE patients
with an index biopsy consistent with LN between January 2005 and July 2015, and
eGFR ? 30mL/min/1.73m(2) were included. Moderate-to-severe TID was defined as the
presence of moderate-to-severe tubular atrophy and/or interstitial fibrosis. Time
to ESRD was defined as time from the index biopsy date to incident ESRD date;
non-ESRD patients were censored at the time of death or the last visit before
December 2015. Time-dependent analyses were conducted to evaluate whether
moderate-to-severe TID was predictive of ESRD progression. RESULTS: Of the 131 LN
patients with eGFR ? 30mL/min/1.73m(2), 17 (13%) patients progressed to ESRD.
Moderate-to-severe TID was present in 13% of biopsies with eGFR ?
60mL/min/1.73m(2) and in 33% of biopsies with eGFR between 30 and
60mL/min/1.73m(2). Moderate-to-severe TID was associated with a higher risk of
ESRD progression: adjusted hazard ratio (HR) = 4.1, 95% CI: 1.4-12.1, p = 0.01
for eGFR ? 30mL/min/1.73m(2); HR = 6.2, 95% CI: 1.7-23.2, p = 0.008 for eGFR ?
60mL/min/1.73m(2). There was no association between tubulointerstitial
inflammation (TII) and ESRD progression. CONCLUSIONS: Moderate-to-severe TID, but
not TII, was a strong predictor of ESRD progression independent of eGFR or
glomerular findings, therefore, providing an important window for potential early
interventions.
