Reduction of insulin-like growth factor-I expression in the skeletal muscle of noncachectic patients with chronic heart failure
We sought to assess the role of insulin-like growth factor-I (IGF-I) in muscle wasting in chronic heart failure (CHF), serum concentrations and local muscular IGF-I expression were determined in patients with severe CHF. Chronic heart failure is associated with progressive muscle atrophy, leading to...

| description | We sought to assess the role of insulin-like growth factor-I (IGF-I) in muscle wasting in chronic heart failure (CHF), serum concentrations and local muscular IGF-I expression were determined in patients with severe CHF.
Chronic heart failure is associated with progressive muscle atrophy, leading to cardiac cachexia. Skeletal muscle disuse and inflammatory activation with elevated cytokine levels have been implicated; however, the pathomechanism involved remains largely unknown.
Serum levels of IGF-I were measured by competitive solid phase immunoassay in 47 patients with severe CHF (left ventricular ejection fraction ≤30%) and 15 age-matched healthy subjects (HS). Insulin-like growth factor-I and IGF-I receptor expression were assessed in vastus lateralis biopsies by real-time PCR and Western blot analysis.
Although serum IGF-I was not significantly different (175 ± 10 ng/ml in CHF vs. 170 ± 12 ng/ml in HS, p = NS), local muscle IGF-I mRNA expression was reduced by 52% in CHF (6.7 ± 0.4 vs. 14.0 ± 0.9 arbitrary units in HS, p < 0.001). This was accompanied by an increase in IGF-I receptor mRNA expression (86.8 ± 5.4 in CHF vs. 23.1 ± 1.8 arbitrary units in HS, p < 0.001). Local IGF-I expression was significantly correlated with muscle cross-sectional area (R = 0.75, p = 0.01). Chronic heart failure patients with a body mass index of |

Chronic heart failure patients with a body mass index of <25 kg/m2showed signs of peripheral growth hormone (GH) resistance, as indicated by elevated serum GH, and reduced IGF-I levels.
In CHF patients, muscle IGF-I expression is considerably reduced in the presence of normal serum IGF-I levels, possibly contributing to early loss of muscle mass. These findings are consistent with a potential role of IGF-I for skeletal muscle atrophy in CHF.</description><identifier>ISSN: 0735-1097</identifier><identifier>EISSN: 1558-3597</identifier><identifier>DOI: 10.1016/S0735-1097(02)01736-9</identifier><identifier>PMID: 11923043</identifier><identifier>CODEN: JACCDI</identifier><language>eng</language><publisher>New York, NY: Elsevier Inc</publisher><subject>Age ; Biological and medical sciences ; Body Mass Index ; Cachexia - etiology ; Cardiology ; Cardiology.
