RESUMO

CONTEXT: Anorexia nervosa (AN) can cause severe undernutrition associated with alterations in the IGF axis. Pappalysins (PAPP-A, PAPP-A2) and stanniocalcins (STC-1, STC-2) modulate IGF binding-protein (IGFBP) cleavage and IGF bioavailability, but their implications in AN are unknown. OBJECTIVE: We determined serum levels of PAPP-As and STCs in relationship with classical IGF axis parameters in female adolescents with AN and their association with nutritional status and secondary amenorrhea. METHODS: Parameters of the IGF axis were determined in fasting serum samples of 68 female adolescents with AN at diagnosis and 62 sex- and age-matched controls. Standardized body mass index (BMI) and bone mineral density (BMD) were calculated. RESULTS: Patients with AN had lower concentrations of total and free IGF-I, total IGFBP-3, acid-labile subunit (ALS), insulin, PAPP-A2, STC-1, and STC-2 and higher levels of IGF-II and IGFBP-2. Their free/total IGF-I ratio was decreased and the intact/total IGFBP-3 and -4 ratios increased. BMI was directly related to total IGF-I and intact IGFBP-3 and inversely with IGFBP-2 and intact IGFBP-4. Weight loss was directly correlated with intact IGFBP-4 and negatively with intact IGFBP-3, ALS, STC-2, and PAPP-A2 concentrations. BMD was directly related to intact IGFBP-3 and inversely with intact IGFBP-4 and PAPP-A2 levels. Patients with amenorrhea had lower levels of total IGF-I and IGFBP-3 than those with menses. CONCLUSION: The reduction of PAPP-A2 in patients with AN may be involved in a decline in IGFBP cleavage, which could underlie the decrease in IGF-I bioavailability that is influenced by nutritional status and amenorrhea.

RESUMO

OBJECTIVE: To explore the feasibility and acceptability of a novel hospital-at-home (HaH) program for adolescent patients with a severe eating disorder (ED). METHOD: Retrospective description of the program during its first year of activity. The feasibility construct is based on accessibility, recruitment, rate of retention, avoidance of hospital stays, and management of crisis situations. Caregivers completed a satisfaction questionnaire on discharge, including an item on perceived safety. All patients referred to the program were included. RESULTS: Fifty-nine female patients with a mean age of 14.69 years (SD = 1.67) were admitted. The mean stay was 39.14 days (SD = 14.47). On admission, 32.2% of patients presented nonsuicidal self-harm behavior and 47.5% had comorbid mental disorders. All patients were screened in the first 48 h after referral, and the program retention rate was 91.52%. As for use of health services, 2016.03 hospital stays were avoided, and only 16.12% of the 31 calls received for urgent care required emergency department visits. Families gave the program an overall satisfaction score of 4.95/5, and all described it as "very safe." DISCUSSION: The HaH program described is a feasible and acceptable care model in adolescents with severe EDs and comorbidities. Effectiveness studies should be performed. PUBLIC SIGNIFICANCE: Eating disorders are a major concern for public health. The adolescent HaH program presented marks an advance in intensive community treatments for patients with severe EDs and comorbidities.

RESUMO

Anorexia nervosa is an eating disorder frequently associated with cutaneous manifestations. A rare type of purpura, known as diffuse reticulate purpura, has been described in patients with anorexia nervosa and severe malnutrition. Typical characteristics of this condition include a purpuric reticulate rash predominantly affecting the trunk that rapidly resolves with adequate feeding. We report two male adolescent patients with anorexia nervosa and severe malnutrition who developed diffuse reticulate purpura.

RESUMO

OBJECTIVE: To present the adaptations to treatment protocols made in a child and adolescent eating disorders (ED) unit during the eight-week confinement period mandated in response to the COVID-19 pandemic and examine clinical and treatment variables in the outpatient, day hospital, and inpatient care programs. METHOD: Description of the implementation of a combined teletherapy program for outpatient and day-hospital patients and the adaptations made to the inpatient protocol. Retrospective review of medical records and analysis of general and specific variables related to the pandemic and confinement. RESULTS: We held 1,329 (73.10%) telehealth consultations and 489 (26.9%) face-to-face outpatient visits with 365 patients undergoing treatment in the outpatient clinic or day hospital. Twenty-eight (7.67%) were initial evaluations. Twenty-two patients were newly admitted and 68 ED-related emergencies were attended. Almost half of the children and adolescents studied experienced reactivation of ED symptoms despite treatment, and severe patients (25%) presented self-harm and suicide risk. CONCLUSIONS: The implementation of a combined teletherapy program has enabled continuity of care during confinement for children and adolescents with ED. Delivery of treatment to adolescents in the day hospital program posed the biggest challenge due to their greater degrees of severity and higher hospitalization rates. An adapted inpatient program should be maintained throughout confinement, as the need for hospitalization of children and adolescents with ED does not decrease with lockdown.
