Abstract
Hereditary hemochromatosis (HH) is a primary iron overload (IO) condition. Absolute telomere length (ATL) is a marker of cellular aging and DNA damage associated with chronic diseases and mortality.
Aim: To evaluate the relationship between ATL and IO in patients with HH.
Methods: Cross-sectional study including25 patients with HH: 8 with IO and 17 without IO (ferritin< 300ng/ml) and 25 healthy controls.
Inclusion criteria were: age>18 years, male sex and HH diagnosis. Patients with diabetes or other endocrine and autoimmune diseases were excluded. ATL was measured by real-time PCR.
Results: HH patients with IO were older (p<0.001) and showed higher ferritin concentration (p<0.001). Patients with HH, disregarding the iron status, showed higher glucose and BMI than controls (both p<0.01). ATL was shorter in patients with IO than controls [with IO: 8 (6-14), without IO: 13 (9-20),and controls: 19 (15-25) kilobase pairs, p<0.01];with a linear trend within groups (p for trend<0.01). Differences in ATL remained statistically significant after adjusting by age, BMI and glucose(p<0.05).
Discussion: Patients with IO featured shorter ATL while patients without IO showed only mild alterations vs. controls. Screening for IO is encouraged to prevent iron-associated cellular damage and early telomere attrition.
Keywords: Iron Metabolism; Iron Overload; Telomere Lenght.

You'd be hard pressed nowadays to find a piece of fish that wasn't contaminated with Mercury
or dioxin or some other pathogen. Similarly most breads contain toxins.
