Abstract Objectives To evaluate the effectiveness of early initiation of angiotensin-converting enzyme inhibitor (ACEi) in patients with scleroderma renal crisis (SRC). Methods This was a retrospective cohort study using a nationwide inpatient database in Japan from July 2010 to March 2020. All hospitalized patients with SRC were divided into those who received ACEi within 2 days of admission (early ACEi group) and those who did not (control group). Propensity-score overlap weighting analysis was performed to adjust for confounding factors. The primary outcome was the composite of in-hospital mortality or haemodialysis dependence at discharge. Results Of the 475 eligible patients, 248 (52.2%) were in the early ACEi group and 227 (47.8%) were in the control group. After overlap weighting, the primary outcome was significantly lower in the early ACEi group than in the control group (40.1% vs 49.0%; odds ratio, 0.69; 95% CI: 0.48, 1.00; P = 0.049). Conclusions The present study showed that early initiation of ACEi was associated with lower composite outcome of in-hospital mortality or haemodialysis dependence at discharge in patients with SRC. Further prospective studies are warranted to verify the present findings.
