Authors' conclusion

In T1DM, MASLD was inversely associated with eGDR and biomarkers of insulin resistance but not with CGM-derived metrics.

Study context

Population
Adults with T1D undergoing vibration-controlled transient elastography (liver stiffness measurement (LSM) and controlled attenuation parameter (CAP)), all with a continuous glucose monitoring (CGM) device; mean age 56 years, mean BMI 26.0 ± 5.9 kg/m²consecutively enrolled
Participants
198 adults
Exposure
MASLD vs no MASLD
  • MASLDn = 73
Outcome
Prevalence of MASLD and significant liver fibrosis (LSM ≥ 7 kPa); association of MASLD with insulin sensitivity (eGDR) and CGM metrics
Methodological detailsmulti-centre, consecutive enrolment

Main finding

As reported in the abstract

Beta coefficient (estimated glucose disposal rate (eGDR))

−0.367

95% CI −0.472 to −0.261

P < 0.001

MASLD (using a CAP threshold of 274 dB/m)
73 (37%)
Significant liver fibrosis among patients with MASLD
16 (8.1%)
Mean eGDR, all patients
7.1 ± 2.3 mg/kg/min

Observational data: associations, not effects.

Further findings

Association of MASLD with CGM-derived metrics

No association between MASLD and CGM-derived metrics

Sensitivity analysis: CAP threshold of 274 dB/m for MASLD

Results were not different
