ABSTRACT
BACKGROUND: 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 including 25 patients with HH: 8 with IO and 17 without IO (ferritin < 300 ng/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 body mass index (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.

Genital tract lymphoma is a rare disease; information on diagnosis, treatment and outcome are limited. We report on eight patients affected by non-Hodgkin's lymphoma of the genital tract, five from the cervix, two from the vagina and one from the vulva collected between 1987 and 1998. Age at presentation ranged from 36 to 82 (median 67) years. The commonest initial symptom was vaginal bleeding, post coital in 1 patient. Three patients complained of vescical symptoms. Ann Arbor classification was stage IAE for 6 patients. Histology, according to the IWF, was either intermediate grade (4 patients), or high grade (3 patients), not evaluable in one case. Seven patients were treated with chemotherapy (anthracycline based in four) followed by pelvic radiotherapy in five; one patient received irradiation alone. Five patients are currently alive and free of disease with follow-up ranging from 8 to 126 months. Based on our experience in this series, we support a management scheme of combination chemotherapy and radiotherapy for patients with non-Hodgkin's lymphoma of the genital tract.
