Introduction: Persistent depressive episodes and subsyndromic depressive symptoms frequently characterize mood alterations in bipolar disorder (BD) and negatively influence quality of life and suicide risk. BD patients with predominant depressive episodes generally show significantly higher treatment resistance rates. Although not specifically approved in Italy for bipolar depression, recently published observational data suggest that the cariprazine add-on may be a potential effective short-term treatment for resistant bipolar depression. Nevertheless data on long-term cariprazine treatment are lacking. Objectives: This study evaluated the efficacy and safety of long-term cariprazine augmentation in patients suffering from treatment-resistant bipolar depression. Methods: 30 resistant bipolar depressed patients, whose resistance was defined according to The CINP Guidelines on the Definition and Evidence-Based Interventions for Treatment-Resistant Bipolar Disorder, were treated with cariprazine 1,5 -3 mg flexible dose for 4 weeks, added to previous mood stabilizing and/or antidepressant treatment. Psychopathology at time 0 and at 4, 8, 12, 16, 20, 24 weeks of treatment was evaluated using the Hamilton Depression Rating Scale (HDRS), the Hamilton Anxiety Rating Scale (HARS), the Young Mania Rating Scale (YMRS) and the Bipolar Depression Rating Scale (BDRS); safety and tolerability was measured by the UKU Side Effect Rating Scale. The drop-out rate was assessed throughout the study duration. Results: Cariprazine add-on was effective in the study sample but only during the first 4 weeks of treatment. Improvement in depression scores started from the first week, reaching about 40% mean HDRS score reduction at T4; a moderate ulterior decrease (-15%) was reached at T24 but was accompanied by a significant drop-out rate; anxiety symptoms improved (mean HARS score reduction 37% at T4) mainly during the first 4 weeks. The treatment was generally well tolerated. From week 4 to 24 we observed a near 70% drop-out rate (18 total drop-outs) with maximum drop-outs between weeks 4-8 (n=7) and 18-24 (n=7). Discontinuation causes were inefficacy (5/18); clinical worsening (10/18); side effects (3/18); hypomanic shift (2/18). Conclusions: Despite the relatively small population examined and the observational design, our results suggest that cariprazine may represent an effective and safe short-term enhancement strategy in resistant bipolar depression. Long-term treatment, in this sample, did not lead to significant improvements and was burdened by a high drop-out rate, mainly due to inefficacy/clinical worsening. Further studies on larger samples are needed to confirm these preliminary findings, both in short-term and in longer observations. Disclosure of Interest: None Declared [ABSTRACT FROM AUTHOR]

Introduction: Anxiety disorders are one of the most common mental illnesses, and a consistent increase was observed after the COVID-19 pandemic. Mindfulness refers to a process that leads to a mental state characterized by nonjudgmental awareness of the present experience. Mindfulness can be considered both a skill and a practice. The stronger is the ability to adopt a mindful state, the less suffering one will experience. While Mindfulness-based Psychotherapies have shown efficacy in their treatment, they have not yet been thoroughly studied in Italian public mental health services. In Detached Mindfulness, negative thoughts are acknowledged and avoided by turning them into actions using a standardized, time-limited, metacognitive intervention. Objectives: The purpose of this study is to examine the efficacy and cost-effectiveness of Detachment Mindfulness for twelve patients with Generalized Anxiety Disorder (GAD) not being treated pharmacologically. Methods: We enrolled 12 patients diagnosed with GAD according to DSM-V in an 8-session program of Detached Mindfulness Psychotherapy (once a week). The Generalized Anxiety Disorder - 7 Scale (GAD-7) and the Kellner Symptom Questionnaire (SQ) were used to assess anxiety symptoms at baseline (T0), after 4 sessions (T1), and at the end of treatment (T2). The Client Satisfaction Questionnaire (CSQ-8) was used to assess treatment satisfaction. Results: The GAD-7 score showed consistent reductions in generalized anxiety symptoms after Detached Mindfulness treatment (mean decrease of -42% at the end of the program). As measured by SQ, patients also reported improvement in physical well-being, relaxation, and somatic symptoms significantly respect to baseline. As for treatment satisfaction, ten out of twelve patients rated their treatment as satisfactory. As reported by patients, mindfulness can become a powerful and effective means to relate to one's own internal experiences such as anxiety or fear, learning to recognize them, staying with them and avoiding their consequences. Conclusions: These results showed that detached mindfulness was an effective and cost-effective intervention for GAD, given the short amount of time it requires and the ease with which it can be implemented. For its extensive use in the public mental health system to be further supported, studies on larger populations are needed. Disclosure of Interest: None Declared [ABSTRACT FROM AUTHOR]

BACKGROUND: Several lines of evidence indicate a role of the brain-derived neurotrophic factor (BDNF) in the modulation of eating behaviour. Therefore, alterations in the physiology of this neurotrophin may be involved in the pathogenesis of eating disorders. In the present study, we investigated serum levels of BDNF in patients with anorexia nervosa (AN), bulimia nervosa (BN) and binge-eating disorder (BED). METHOD: Ninety-nine drug-free women (27 with AN, 24 with BN, 24 with BED and 24 healthy controls) underwent both a blood sample collection in the morning and diagnostic and psychopathological assessments by means of structured clinical interviews and ad-hoc rating scales. Serum levels of BDNF, 17 beta-oestradiol, FT3 and FT4 were measured. RESULTS: Compared to healthy controls, serum levels of BDNF were significantly reduced in underweight AN women and in normal weight BN women, but not in overweight BED women. Changes in circulating BDNF levels were not affected by the presence of co-morbid depressive disorders. No significant correlation emerged between neurotrophin concentrations and psychopathological, nutritional, demographic and hormonal variables. CONCLUSIONS: These findings evidentiate alterations in serum BDNF levels in malnourished patients with AN or BN, but not in well-nourished individuals with BED. Since BDNF seems to exert a satiety effect, its reduction may represent an adaptive change to counteract the decreased calorie ingestion of AN and BN individuals. [ABSTRACT FROM AUTHOR]

Background: Ghrelin and leptin are endogenous peripheral proteins involved in the regulation of eating behaviour. In particular, ghrelin stimulates hunger and promotes food ingestion, whereas leptin increases satiety and reduces food consumption. Therefore, alterations in the physiology of these peptides may play a role in the pathogenesis of eating disorders such as bulimia nervosa. In the present study, we investigated ghrelin and leptin responses to food ingestion in patients with bulimia nervosa., Method: Nine symptomatic drug-free bulimic women and 12 age-matched healthy women ingested a meal of 1207 kcal (60% carbohydrates, 23% fat and 17% proteins) at 12.00 a.m. and underwent blood sample collection before and 45, 60, 90, 120 and 180 min after the meal. Plasma levels of ghrelin, leptin, insulin and glucose were measured., Results: In healthy women, circulating ghrelin exhibited a drastic decrease after the food intake whereas, in bulimic patients, this response was significantly blunted. No difference between the two subjects groups was observed in post-prandial profiles of plasma leptin, insulin and glucose., Conclusions: The lack of a leptin response to food ingestion, in both bulimic and healthy women, is compatible with the role of this peptide as long-term rather than short-term modulator of eating behaviour. The blunted ghrelin response to food ingestion may support the occurrence in bulimic subjects of an impaired suppression of the drive to eat following a meal. This may have implications for binge-eating.
