ABSTRACT
Objective:
To explore the function of serum leptin in COPD patients with malnutrition, and to investigate the relationship between leptin and TNF-?.Methods:
A total of 81 subjects (47 COPD patients and 34 control subjects) participated in this study. The 47 COPD patients were divided into 2 groups group COPD Ⅰ (patients without malnutrition during stable disease, n=29), group COPDⅡ(patients with malnutrition during stable disease, n=18).To eliminate the effect of sex differences, all the patients and controls were male. Body mass index (BMI), percent ideal body weight (IBW%), triceps skin-fold thickness (TSF), mid-upper arm circumference (MAC), mid-upper arm muscle circumference(MAMC),serum leptin and tumor necrosis factor-?(TNF-?) levels, serum prealbumin (PA), serum transferrin (TF), serum albumin(Alb),total lymphocytes count (TLC), forced expiratory volume in one second (FEV_1), maximal inspiration pressure(MIP)and maximal expiration pressure(MEP)were measured in all participants. Leptin levels were measured by radioimmunoassay. TNF-? levels were measured by ELISA. The between group difference and correlation of these parameters were analysed.Results:
(1)Serum leptin levels were significantly lower in group COPDⅡ (4.07?3.42 ?g/L) than in group COPD Ⅰ(9.72?6.67 ?g/L)and controls(8.21?5.41 ?g/L, P
