AIMS: Alcoholism may be a cardiovascular risk factor. Osteocyte derived molecules such as fibroblast growth factor 23 (FGF-23) and soluble α Klotho have recently been associated with cardiovascular disease, but their role in alcoholics is unknown. We here analyze the behavior of FGF23 and α Klotho in alcoholics.
METHODS: Ninety-seven alcoholic patients were assessed for liver function, presence of hypertension, diabetes, atrial fibrillation, left ventricular hypertrophy (LVH), vascular calcifications (assessed by chest X-ray) and nutritional status (lean and fat mass measured by densitometry). We measured plasma levels of FGF-23 and serum soluble α Klotho, using ELISA in 97 patients and 20 age- and sex-matched controls.
RESULTS: FGF-23 levels were higher in patients than in controls (Z = 3.50; P < 0.001). FGF-23 (Z = 5.03; P < 0.001) and soluble α Klotho (Z = 5.61; P < 0.001) were higher in cirrhotics, and both were related to liver function, independently of serum creatinine FGF-23 levels were higher among alcoholics with diabetes (Z = 2.55; P = 0.011) or hypertension (Z = 2.56; P = 0.01), and increased body fat (ρ = 0.28; P = 0.022 for trunk fat), whereas α Klotho levels were higher in patients with LVH (Z = 2.17; P = 0.03) or atrial fibrillation (Z = 2.34; P = 0.019).
CONCLUSIONS: FGF-23 was higher in alcoholics than in controls, especially among cirrhotics, and soluble α Klotho levels were also higher among cirrhotics. Both were related to liver function impairment, independently of serum creatinine levels, and also showed significant associations with vascular risk factors, such as hypertension, diabetes or trunk fat amount in the case of FGF-23, or LVH or atrial fibrillation in the case of α Klotho.
SHORT SUMMARY: We report increased values of fibroblast growth factor 23 (FGF-23) and soluble α Klotho in cirrhotic alcoholics. Both molecules are associated with liver function impairment, and with some cardiovascular risk factors such as diabetes, hypertension, increased body fat, left ventricular hypertrophy and atrial fibrillation independently of serum creatinine.
