TNNT2 and lupus nephritis: Interestingly in our series, the percentage of SLE patients with past lupus nephritis were higher (64% vs 35%; p = 0.039) and the eGRF was lower (72 (54–122) vs 105 (63–127) ml/min/1.73 m2; p = 0.026) in patients with detectable HS-cTnT as compared to those with undetectable HS-cTNT.
