Introduction: The aim of this study was to investigate the association between the genetic background of coagulation factors and the presence of oligo- or amenorrhea in adolescent girls diagnosed with anorexia nervosa compared with controls.

Patients and Methods: A total of 40 adolescent girls diagnosed with anorexia nervosa aged 14–17 years, as well as 10 age-matched girls, were included in the study. We recorded anthropometric parameters and calculated body mass index (BMI) z-scores adjusted for age, as well as duration of amenorrhea. Blood samples were obtained for genotyping and hormonal assessment. Genetic polymorphisms of MTHFR (methylenetetrahydrofolate reductase C677T and A1298T), GpIIb/IIIa (glycoprotein IIb/IIIa) and prothrombin were investigated.

Results: Presence of the GpIIIa Leu33/Pro was evident almost solely in the subgroup of anorexic girls (cases vs controls, 27.6% vs 5.9%, P-value = 0.073). Anorexic girls had higher odds than controls to carry: i) the GpIIa leu33/pro or G20210A mutation (34.5% vs 5.9%, P-value = 0.028) ; ii) the GpIIIa Leu 33/Pro mutation or the MTHFR A1298C (62.1% vs 29.4%, P-value = 0.032). Furthermore, girls with oligo- or amenorrhoea compared with girls presenting with normal menses had significantly higher prevalence of: i) the GpIIIa Leu33/Pro mutation (30.3% vs 5.9%, P-value = 0.048) ; ii) GpIIIa Leu33/Pro or the G20210A mutation (36.4% vs 5.9%, P-value = 0.020) ; iii) any mutation from the panel, consisting of the GpIIIa Leu33/Pro or MTHFR A1298C (60.6% vs 29.4%, P-value = 0.037). Logistic regression analysis proved that the presence of any mutation from the panel, consisting of G20210A or the GpIIIa Leu33/Pro mutation, as well as levels of estrogen, predict the development of amenorrhoea (OR 15.618, P-value = 0.043), in a model adjusted for age, BMI z-score and diagnosis of anorexia nervosa.

Conclusions: Genetic background of coagulation factors can predict the presence of oligo- or amenorrhea in girls diagnosed with anorexia nervosa.
