Purpose: Functional hypothalamic amenorrhea (FHA) is characterized by an estrogen deficiency which in turn can cause vascular dysfunction. The aim of this study is to evaluate any changes in the chorio-retinal circulation in patients affected by FHA. 24 patients with FHA and 24 age-matched controls underwent a gynecological evaluation and an OCT angiography (OCTA) to study chorio-retinal vascularization. Results: OCTA in FHA patients showed an increase in vessel density in the choriocapillaris (CC) layer (both in the fovea area, at 5% p value = 0.037 and in the whole area, at 5% p value = 0.028) and an increase in vascular density in the deep fovea (DVP) (at 10% p value = 0.096) in the whole district compared to controls. Simple linear regressions show a significant negative association between CC vessel density and insulin (p = 0.0002) and glucose values (p = 0.0335) for the fovea district and a negative association between DVP vessel density and endometrial thickness (at 10%, p value: 0.095) in the whole district. Conclusion: Our study shows that CC vessel density is increased in women affected by FHA. This could represent a compensation effort to supply the vascular dysfunction caused by estrogen deficiency. We also found an increasing trend in vascular density in DVP associated with the decrease of endometrial thickness, an indirect sign of estrogenization. Considering that these changes occur in absence of visual defects, they could be used as a biomarker to estimate hypoestrogenism-induced microcirculation changes before clinical appearance.

Purpose: To ascertain the role of deranged eating behaviours (DEBs) in the development of functional hypothalamic amenorrhoea (FHA) and the reciprocal role of psychopathological traits on both disorders.Methods: A prospective case-control study was conducted spanning the period January 2016 to April 2018. Forty-one consecutive FHA females and 86 healthy controls were recruited. We assessed the DEBs and other FHA predisposing factors via self-reported questionnaires. Possible correlations amongst the variables were examined using the Spearman's correlation coefficient (rho), whilst multivariate logistic regression was carried out to identify independent predictors of DEBs.Results: Mean scores on Eating Attitudes Test-26 (EAT-26) were significantly higher in females with FHA (p < 0.0001). Women with FHA were characterised by significantly higher scores at the sub-scale items of dieting (p = 0.03) and bulimia and food preoccupation (p < 0.001) compared to healthy controls. Significant difference was also observed between the mean scores of the two groups in all other questionnaires: State-Trait-Anxiety-Inventory (STAI) (p < 0.0001), Multidimensional Body-Self-Relations Questionnaire (MBSRQ) (p < 0.0001) and International Physical Activity Questionnaire (IPAQ) (p = 0.004). EAT-26 scores were positively correlated with scores on STAI (ρ = 0.26, p = 0.04), MBSRQ (ρ = 0.79, p < 0.0001) and IPAQ (ρ = 0.35, p = 0.03). High scores on IPAQ and STAI were correlated with a 12.2-fold (p = 0.008) and 4.3-fold (p = 0.04) increased risk for high scores on EAT-26 respectively.Conclusions: DEBs may occur in FHA populations at a higher frequency compared to the general population. Anxiety and overweight preoccupation may underlie and independently contribute to development and maintenance of both DEBs and FHA. This evidence may have future implications for both screening and interventions that target DEBs and other psychological factors. [ABSTRACT FROM AUTHOR]
