摘要

Background and aims

Systemic sclerosis (SSc) is a systemic autoimmune disease characterized by fibrosis, vascular abnormalities, and immune dysfunction. Whether patients with SSc exhibit lipid profile abnormalities, which may increase cardiovascular risk, remains uncertain. Our aim was to systematically investigate whether total cholesterol (TCHOL), triglycerides (TRG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and Lipoprotein (a) [Lp(a)] are affected in SSc patients.

Methods

PubMed and Cochrane library databases were systematically searched up to 30 November 2024 for studies reporting on lipid profile (TCHOL, TRG, HDL-C, LDL-C) and Lp(a) in patients with SSc. Qualitative and quantitative syntheses of data from published prospective and retrospective studies was performed.

Results

Literature search identified 27 eligible trials including 2503 participants, of whom 1114 were SSc patients and 1389 were healthy controls (HC). The pooled analysis from 24 studies (1001 SSc patients and 1254 HC) demonstrated that SSc patients had significantly lower HDL-C levels compared with the HC group (MD:– 5.61 mg/dl, 95% CI– 8.22,– 3.00, I2 = 83%). Regarding TRGs, pooled analysis from 24 studies (1016 SSc patients and 1246 HC) showed significantly higher levels in SSc compared with HC (MD: 16.98 mg/dl, 95% CI 8.28, 25.68, I2 = 68%). Similarly, the pooled analysis from 3 studies (131 SSc patients and 206 HC) showed significantly higher Lp(a) levels in SSc compared with HC (MD: 15.66 mg/dl, 95% CI 6.77, 24.55, I2 = 5%). No significant differences were observed in TCHOL (MD: 0.94 mg/dl, 95% CI– 10.23, 12.10, I2 = 93%), and LDL-C (MD:– 6.12 mg/dl, 95% CI– 16.00, 3.77, I2 = 95%) levels between SSc and HC groups.

Conclusions

HDL-C levels are decreased in SSc, contrary to TRG and Lp(a) levels, which are increased. These findings may have implications in assessing cardiovascular risk in patients with SSc.
