Abstract
ObjectiveTo describe the characteristics of the patients, as well as the treatment outcomes for the people treated in an Endocrinology and Nutrition unit with a diagnosis of SE-ED (> 7 years evolution despite evidence-based conventional treatment).MethodsA descriptive observational study was conducted. Patients with a diagnosis of SE-ED (anorexia nervosa and bulimia nervosa) treated in the Endocrinology and Nutrition service of the Virgen del Rocío University Hospital between 2014 and 2019 were included.Results67 patients were contacted and accepted to participate in the study. 95.5% were women. 67.2% were diagnosed with AN (anorexia nervosa) and 32.8% with BN (bulimia nervosa). Their median ages (years) at the onset of symptoms, beginning of follow-up and at present were 17, 32 and 42.5 respectively. Their median time of follow-up was 9 years. 73.1% had mental comorbitidy and AN patients had more osteoporosis (48.9% vs 22.7%, p = 0.04) and hypogonadotropic hypogonadism (31.1% vs. 4.5%, p = 0.014).DiscussionThe SE-ED patients in our sample began treatment years after the onset of symptoms, which may have led to their chronification. This emphasizes the importance of an early diagnosis in eating disorders. They presented with a high rate of physical complications and mental comorbidity. In the current sample, it was determined that patients with AN presented with higher rates of osteoporosis and hypogonadotropic hypogonadism than patients with BN.Level of evidenceLevel III: Evidence obtained from well-designed cohort or case–control analytic studies.Plain English summaryAt present, the criteria for severe and enduring eating disorders (SE-ED) are not sufficiently clearly defined. It has been calculated that approximately 20% of patients with anorexia nervosa (AN) and 10% of patients with bulimia nervosa (BN) suffer a chronification. We evaluated the characteristics of the patients, as well as the treatment outcomes for the people treated in an Endocrinology and Nutrition unit with a diagnosis of SE-ED (which was made based on an evolution greater than 7 years despite conventional treatment). The SE-ED patients in our sample began treatment years after the onset of symptoms, which may have led to their chronification. They presented with a high rate of physical complications and mental comorbidity. In the current sample, it was determined that patients with AN presented with higher rates of osteoporosis (health condition that weakens bones, making them fragile and more likely to break) and hypogonadotropic hypogonadism (illness in which testes or ovaries produce little or no sex hormones due to a problem in the pituitary gland) than patients with BN.
