Diversité des prises en charge hospitalières de l'anorexie mentale en psychiatrie en France

International audienceBackground: Hospitalization is rare in anorexia nervosa (AN) and local application of indications is heterogeneous. However, no study has evaluated the effect of these different treatment modalities on the mean length of stay. Our objective was to describe the context and modalities of a wide range of hospital care programs offered to patients with anorexia nervosa in eleven specialized French psychiatric centers for patients from childhood to adulthood. This work was carried out within the framework of the EVHAN (Evaluation of Hospitalization for AN, Eudract number: 2007-A01110-53, registered in Clinical trials) research program. The EVHAN program comprises five main lines: weight objectives at discharge, the practice or not of a separation period, the use of clear nutritional dietary objectives (cognitive/behavioral), the intensity of family involvement in treatment, and the existence or absence of a stabilization phase before ending inpatient treatment. These main lines will make it possible to study the impact of treatment modalities on the future of patients in the short and medium term (at discharge and at 1-year follow-up). Methods: The eleven centers are located in France (Bordeaux, Nantes, Paris and Ile-de-France, Rouen and Saint-Étienne). Various staff members (psychiatrists, somatic doctors, nurses, dieticians, psychologists) from each center were interviewed using a semi-structured questionnaire. Data on operating modalities and context of care were collected and analyzed. Results: Four of the eleven centers were exclusively child/adolescent centers, and seven of 11 were adolescent (from 11, 13 or 16 years) and young adult centers. All centers offered a graduated approach from outpatient to full hospitalization. The majority had a number of beds allocated for patients with eating disorders. The criteria for hospitalization were homogeneous with respect to somatic and/or psychic severity prefiguring the consensus criteria defined by the French Health Authority (HAS) in 2010. Child/adolescent units used the weight curve to set weight objectives at discharge (between the 10th and 50th percentiles). Most adult units used weight objectives at discharge corresponding to a body mass index between 17 and 20 kg/m2. Nine centers used a written or oral care contract. One unit did not separate the patient from her/his usual environment, the others had a practice gradient of partial separation and total separation times. These were either short, lasting a maximum of 3 weeks, or long, lasting more than 3 weeks. Conversely, patients were not isolated within the unit, and benefited from a rich social life, depending on her/his physical condition. The patient's family was in contact with the team and fully supported. The longest periods of separation involved adolescents and adults. Nutritional support varied from a group approach (meals in the dining room, standardized meals of the care center) to very individualized approaches within a specific framework. All the units reported meeting with families at least once during the hospitalization; with the patient's parents for child/adolescent patients and/or unmarried patients and with the husband/wife for married patients. The majority of the centers requested a phase of weight stabilization, whatever the age before hospital discharge. Conclusion: There is international and national consensus regarding the indications for hospitalization, and the main lines of multidisciplinary care to be developed within this framework. However, local application of these indications was heterogeneous resulting in diverse modalities of hospital care for anorexia nervosa in France. Specialized teams have developed management strategies arising from their “team culture”. The complexity of the anorexic pathology, due to the psyche-soma intrication and the diversity of age groups, highlights the complexity of care available. The impact of this diversity of hospital care on patient outcomes will be studied as a result of this work

Caregivers in anorexia nervosa: is grief underlying parental burden?

AUTEURS : The members of the EVHAN GroupInternational audiencePurpose: Anorexia Nervosa (AN) is a severe chronic disorder and parents’ experience of caregiving is usually marked by emotional distress and burden. Severe chronic psychiatric disorders are known to be linked with the concept of grief. Grief has not been investigated in AN. The aim of this study was to explore parents’ and adolescents’ characteristics that may be related to parental burden and grief in AN, and the link between these two dimensions. Methods: Eighty mothers, 55 fathers and their adolescents (N = 84) hospitalized for AN participated in this study. Evaluations of clinical characteristics of the adolescent’s illness were completed, as well as self-evaluations of adolescent and parental emotional distress (anxiety, depression, alexithymia). Levels of parental burden were evaluated with the Experience of Caregiving Inventory and levels of parental grief with the Mental Illness Version of the Texas Revised Inventory of Grief. Results: Main findings indicated that the burden was higher in parents of adolescents with a more severe AN; fathers’ burden was also significantly and positively related to their own level of anxiety. Parental grief was higher when adolescents’ clinical state was more severe. Paternal grief was related to higher anxiety and depression, while maternal grief was correlated to higher alexithymia and depression. Paternal burden was explained by the father’s anxiety and grief, maternal burden by the mother’s grief and her child’s clinical state. Conclusion: Parents of adolescents suffering from AN showed high levels of burden, emotional distress and grief. These inter-related experiences should be specific targets for intervention aimed at supporting parents. Our results support the extensive literature on the need to assist fathers and mothers in their caregiving role. This in turn may improve both their mental health and their abilities as caregivers of their suffering child. Level of evidence: Level III: Evidence obtained from cohort or case-control analytic studies

Effects of azithromycin and doxycycline on the vaginal microbiota of women with urogenital Chlamydia trachomatis infection: a substudy of the Chlazidoxy randomized controlled trial

Objectives: Dysbiotic bacterial communities within the vagina are associated with Chlamydia trachomatis infection. We compared the effect of treatment with azithromycin and doxycycline on the vaginal microbiota in a cohort of women with a urogenital C. trachomatis infection randomly assigned to one of these treatments (Chlazidoxy trial). Methods: We analysed vaginal samples from 284 women (135 in the azithromycin group and 149 in the doxycycline group) collected at baseline and 6 weeks after treatment initiation. The vaginal microbiota was characterized using 16S rRNA gene sequencing and classified into community state types (CSTs). Results: At baseline, 75% (212/284) of the women had a high-risk microbiota (CST-III or CST-IV). A crosssectional comparison 6 weeks after treatment showed that 15 phylotypes were differentially abundant, but this difference was not reflected at the CST (p 0.772) or diversity level (p 0.339). Between baseline and the 6-week visit, a-diversity (p 0.140) and transition probabilities between CSTs were not significantly different between the groups, and no phylotype was differentially abundant. Discussion: In women with urogenital C. trachomatis infection, the vaginal microbiota does not seem to be affected by azithromycin or doxycycline 6 weeks after treatment. Because the vaginal microbiota remains susceptible to C. trachomatis infection (with CST-III or CST-IV) after antibiotic treatment, women remain at risk of reinfection, which could originate from unprotected sexual intercourse or untreated anorectal C. trachomatis infection. This last consideration advocates for the use of doxycycline instead of azithromycin because of its higher anorectal microbiological cure rate.
