Correlation of serum lipid profile and disease activity in patients with inflammatory bowel disease / 中华内科杂志

ABSTRACT

To analyze the correlation between lipid profile and disease activity in patients with inflammatory bowel disease (IBD).A total of 307 Crohn′s disease (CD) patients, 232 ulcerative colitis (UC) patients and 165 healthy subjects from the same geographic region were included. Total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and lipoprotein(a)[Lp(a)] were retrieved from their medical records. Crohn disease activity index (CDAI) and Mayo scores were calculated as measurement of disease severity for CD and UC separately. Patients with CD and UC had lower TC, TG, HDL-C and LDL-C levels than those in control group ( P<0.05). Additionally, CDAI was negatively associated with TC, HDL-C and LDL-C levels ( r=-0.218, -0.210, -0.176, P<0.05), while TG level was not associated with CDAI. Mayo scores was not significantly associated with TC, HDL-C, LDL-C and TG. Patients with CD had higher Lp(a) levels than those in UC and control group ( P<0.05). Furthermore, patients with active CD had higher Lp (a) levels than those with inactive disease ( P<0.05).The Lp(a) levels in CD patients were positively associated with CDAI ( r=0.151, P<0.05), while Lp(a) level in UC group was nor assocriated with Mayo score. Patients with IBD have dyslipidemia and lipid profile is associated with disease activity in CD patients.
