You will be provided with the titles and abstracts of a collection of medical RCT reports studying a clinical question -- for instance, the efficacy of an intervention on some medical outcome. Please write a few sentences synthesizing the findings of these reports, which could serve as a conclusion section for a systematic review article. Your response should not include any other text. The RCT reports are below.



Title 1:
Hunger, food intake and weight: the impact of clomipramine on a refeeding anorexia nervosa population.
Abstract 1:
This double-blind controlled study examines the impact of clomipramine when taken by an anorexia nervosa population, refeeding in hospital, over and above that generated by the established treatment programme. Of the 16 patients studied, all reached their target weights including three who asked to leave the study. Clomipramine was significantly associated with increased hunger, appetite and energy intake. It tended, though, to be associated with a reduced rate of weight gain, possibly because activity was increased. Patients receiving clomipramine were more stable in their eating habits and maintained body weight better than those on placebo after leaving the trial. These findings indicate the sensitivity of the hypothalamus to changes in body weight. Clomipramine, which is known to act at a hypothalamic level, seems to influence hunger, appetite and dietary intake according to the body weight of the patient. The threshold weights which have been shown to trigger hypothalamic sexual responses, may also influence hunger, appetite, motility and voluntary energy intake.


Title 2:
A single blind comparison of amisulpride, fluoxetine and clomipramine in the treatment of restricting anorectics.
Abstract 2:
1. The study evaluated the efficacy of amisulpride, fluoxetine and clomipramine at the beginning of the re-feeding phase of the treatment of restricting anorexia nervosa according to DSM-IV criteria. 2. 13 patients, mean weight 37.61 kg +/- 9.80 SD, were treated with clomipramine at a mean dosage of 57.69 mg +/- 25.79 SD; 10 patients, mean weight 40.90 kg +/- 6.98 SD, were treated with fluoxetine at a mean dosage of 28.00 mg +/- 10.32 SD; 12 patients, mean weight 38.41 kg +/- 8.33 SD, were treated with amisulpride at a mean dosage of 50.00 mg +/- 0.00 SD. 3. Clinical evaluation was carried out under single-blind condition at basal time and after three months by a structured clinical interview, the Eating Disorder Interview based on Long Interval Follow-up Evaluation (LIFE II BEI). 4. Patients treated with amisulpride showed a more significant increase (p=0.016) of mean weight. Concerning weight phobia, body image disturbance and amenorrhoea, no significant difference resulted.


Title 3:
Combined cognitive-behavioral, psychopharmacological and nutritional therapy in eating disorders. 2. Anorexia nervosa--binge-eating/purging type.
Abstract 3:
Thirteen women with anorexia nervosa, binge-eating/purging type (AN-BP), 17-43 years old, were treated with a 4-month course of combined cognitive-behavioral, nutritional and antidepressant therapy (7 with amineptine and 6 with fluoxetine). Patients were monitored before and after 1, 2 and 4 months of treatment for body mass index (BMI), for eating disorder symptoms by the Eating Disorder Inventory (EDI) and the Bulimic Investigation Test (BITE) and for depression and anxiety by the Hamilton Rating Scales for Depression and for Anxiety. BMI, EDI scores, depression and anxiety improved significantly and equally in the two groups during the 4 months of therapy, while BITE scores did not change.


Title 4:
Amitriptyline in the treatment of anorexia nervosa: a double-blind, placebo-controlled study.
Abstract 4:
The tricyclic antidepressant drug amitriptyline was evaluated as a short-term treatment of anorexia nervosa patients. In a 5-week double-blind, placebo-controlled study 11 patients were given amitriptyline and 14 received placebo. In addition, 18 patients who refused to participate in the drug trial and received only psychosocial treatment were used as an additional comparison group. Overall, patients in the three groups showed little improvement. No statistically significant differences favoring amitriptyline were found in any of the outcome variables. Plasma levels varied widely among patients receiving similar doses. No association was found between plasma levels and improvement in either psychiatric symptomatology or weight. Amitriptyline patients did not manifest any tendency for a reduction of depressive symptomatology. In addition, amitriptyline treatment was associated with substantial discomfort and adverse affects.


Title 5:
Combined cognitive-behavioral, psychopharmacological and nutritional therapy in eating disorders. 1. Anorexia nervosa--restricted type.
Abstract 5:
Twenty-two female patients with anorexia nervosa, restricted type, 14-35 years old, were treated with a 4-month course of combined cognitive-behavioral therapy, nutritional counselling and antidepressant drugs (nortriptyline for 7, fluoxetine for 15). Patients were monitored for body mass index (BMI), for eating disorder symptoms by the Eating Disorder Inventory (EDI) and the Bulimic Investigation Test (BITE) and for depression and anxiety by the Hamilton Rating Scales for Depression and for Anxiety (HRS-D and -A). The scores were determined before and after 1, 2 and 4 months of therapy. BMI, depression, anxiety and EDI scores improved significantly and equally in both groups during the 4 months of therapy, while BITE scores did not change.


Title 6:
Anorexia nervosa. Treatment efficacy of cyproheptadine and amitriptyline.
Abstract 6:
Patients with anorexia nervosa have concurrent problems of emaciation and depression. Therefore, treatment with medications affecting both weight gain and depression seemed reasonable. Seventy-two anorectic patients were randomly assigned in a double-blind study to receive cyproheptadine hydrochloride, a weight-inducing drug, amitriptyline hydrochloride, a tricyclic antidepressant, or placebo. Overall, cyproheptadine had a marginal effect on decreasing the number of days necessary to achieve a normal weight. There was a differential drug effect present in the bulimic subgroups of the anorectic patients: cyproheptadine significantly increased treatment efficiency for the nonbulimic patients and significantly impaired treatment efficiency for the bulimic patients when compared with the amitriptyline- and placebo-treated groups. The differential cyproheptadine effect on the anorectic bulimic subgroups is the first pharmacologic evidence of the validity of these subgroups. Cyproheptadine had an anti-depressant effect demonstrated by a significant decrease in the Hamilton depression ratings.


Title 7:
Does fluoxetine augment the inpatient treatment of anorexia nervosa?
Abstract 7:
While pharmacological interventions are of established utility in bulimia nervosa, medications have no clear role in the treatment of anorexia nervosa. Because patients with anorexia nervosa frequently exhibit mood disturbances and symptoms of obsessive-compulsive disorder, the authors tested the utility of fluoxetine in the treatment of women participating in an inpatient program for anorexia nervosa.
                The authors conducted a randomized, placebo-controlled, double-blind, 7-week study of fluoxetine at a target daily dose of 60 mg in 31 women with anorexia nervosa receiving treatment for their eating disorder on a clinical research unit. Body weight and measures of eating behavior and psychological state were obtained at baseline and at termination.
                There were no significant differences in clinical outcome on any measure between patients receiving fluoxetine and patients receiving placebo.
                Fluoxetine does not appear to add significant benefit to the inpatient treatment of anorexia nervosa.
A lack of quality information precludes us from drawing definite conclusions or recommendations on the use of antidepressants in acute AN. Future studies testing safer and more tolerable antidepressants in larger, well designed trials are needed to provide guidance for clinical practice.
