S-Adenosylmethionine (SAMe) in major depressive disorder (MDD): a clinician-oriented systematic review.

BACKGROUND: Major depressive disorder (MDD) is a recurrent illness with high rates of chronicity, treatment-resistance, and significant economic impact. S-Adenosylmethionine (SAMe), a molecule that is formed naturally in the human body, has shown antidepressant effects and may expand the available options for treating MDD. This systematic review examines the evidence concerning the efficacy of SAMe as monotherapy or in combination with antidepressants. METHODS: A systematic search in Medline, Psychinfo, AMED, and Cochrane Controlled Trials Register was conducted for any reference recorded up to March 2020. Double-blind, randomised controlled trials, comparing the antidepressant efficacy of SAMe to placebo or/and to other antidepressants, were selected. Two authors evaluated each study independently and then, reconciled findings. RESULTS: Eight trials, with a total of 11 arms and 1011 subjects, evaluating the efficacy of SAMe used as monotherapy or as adjunctive therapy (512 individuals), were included in this review. The study duration ranged between 2 and 12 weeks and the daily dose of SAMe varied from 200 to 3200 mg. Five comparisons evaluated the differences between SAMe and placebo and SAMe resulted significantly better than placebo in three of these studies. Four comparisons evaluated the differences between SAMe and other antidepressants (imipramine or escitalopram) and showed no significant difference. One study showed that SAMe was significantly better than placebo in accelerating the response to imipramine from day 4 to day 12, but the mean scores were not statistically different at the day 14 endpoint. One study showed that SAMe combined with serotonin reuptake inhibitors (SSRI) was better than PBO combined with SSRI. The studies reported only mild, transient or non-clinically relevant side effects. CONCLUSIONS: The existing trials of SAMe, used as monotherapy or add on to another antidepressants, have shown encouraging and generally positive results. However, more evidence is necessary before definitive conclusions can be drawn. Larger, double-blind randomised controlled studies are warranted to confirm the antidepressant effectiveness of SAMe.

Advances in treatment for postpartum major depressive disorder.

Introduction: Postpartum depressive disorder (PPD) is a burdensome medical condition. To date, only one treatment (Brexanolone) has undergone registrational trials and is approved in the United States with an indication for the treatment of PPD. However, other treatments are prescribed and have been tested for this condition. Herein, the authors review the available scientific evidence pertaining to the somatic treatments of PPD. Areas covered: The authors evaluate the published open-label and randomized controlled trials (RCTs), examine the biological mechanisms of PPD treatments, and evaluate how the available data translates into information that may be useful for clinical practice. Expert opinion: Antidepressants have long been the mainstay of PPD treatment, despite the limited evidence from randomized clinical trials that supports this practice. Brexanolone improves treatment options for women with PPD. However, the relatively burdensome administration and monitoring protocol, along with the high cost of the medication, limit the possibility for an extensive use of this medication. Large, randomized, controlled trials of hormonal treatments in patients with PPD are warranted. Also, treatment with mood stabilizers and/or antipsychotics in women with major depressive disorder, who meet the DSM-5 mixed features specifiers in the post-partum period, should be tested in controlled clinical trials.

Drug safety evaluation of aripiprazole in bipolar disorder.

Introduction: Safety and tolerability of medications are key variables to inform treatment choice for patients with bipolar disorder (BD). This review focuses on the overall tolerability and safety profile of aripiprazole when used for its bipolar disorder indications, which include acute treatment of manic and mixed episodes and maintenance treatment of bipolar I disorder for the oral formulation, agitation associated with bipolar mania for the injectable immediate-release formulation, and maintenance treatment of bipolar I disorder for the long acting once-monthly (AOM) formulation. Areas covered: The authors reviewed aripiprazole safety in bipolar disorder according to product labeling. English language reports located through PubMed and information available on the US Food and Drug Administration (FDA) and European Medicines Agency (EMA) websites, with a focus on the safety and tolerability of aripiprazole, were reviewed. Expert opinion: Compared to many other antipsychotics, aripiprazole has a relatively favorable tolerability profile, with a lower risk for weight gain, dyslipidemia, diabetes, and hyperprolactinemia. Compared to first-generation antipsychotics, and similar to most second-generation antipsychotics, aripiprazole has a reduced propensity for extrapyramidal side effects and a better cardiovascular safety.

Prevalence and Correlates of Vitamin D Deficiency in a Sample of 290 Inpatients With Mental Illness.

Introduction: Vitamin D inadequacy or deficiency (VDID) has been reported in a high percentage of otherwise healthy individuals. Factors that may contribute to the high prevalence of VDID in people with mental disorders include diet low in vitamin D, poor sunlight exposure, decrease in cutaneous vitamin D synthesis, intake of certain medications, poor mobility, excessive alcohol intake, and tobacco smoking. VDID has been correlated to a host of adverse conditions, including rickets, osteoporosis, osteomalacia, muscle diseases, depression, cognitive dysfunction, and even certain cancers. Objectives: The purpose of this study was to report the prevalence and correlates of vitamin D inadequacy in a sample of 290 psychiatric patients admitted to inpatient or day hospital treatment at the University of Siena Medical Center. Methods: We retrospectively evaluated the prevalence of VDID in 290 psychiatric inpatients' medical records during the year 2017 and evaluated the correlates of VDID in patients with mental illness. Results: Two hundred and seventy two out of two hundred and ninety patients (94%) showed VDID. Physical activity and regular diet were positively correlated with vitamin D levels whereas age, tobacco smoking, PTH, alkaline phosphatase levels were negatively correlated. Statistically significant differences were found among smokers and non-smokers in all study groups. Conclusions: VDID was highly prevalent in our sample. In addition to vitamin D supplementation, psychosocial intervention able to promote and help sustain physical activity, appropriate diet, quitting smoking and sensible sun exposure to prevent and treat VDID in patients with mental health should be implemented, tested, and introduced in our clinical practice.

Principi di farmacodinamica e farmacocinetica nello switch tra antipsicotici: focus su cariprazina.

Cariprazina {RGH-188; trans-N- [4- [2- [4- (2,3-diclorofenil) piperazin-1-il] etil] cicloesil] -N_, N_-dimetilurea cloridrato} è un antipsicotico atipico di nuova generazione, con un originale profilo farmacodinamico e farmacocinetico. Cariprazina ha due metaboliti attivi, uno dei quali ha un'emivita di 1-3 settimane, che è la più lunga di qualsiasi antipsicotico atipico, con emivita effettiva funzionale totale (cariprazina più due metaboliti) di 7 giorni. Il farmaco mostra un'affinità che è circa 10 volte più alta per i recettori D3 che per D2 (rispettivamente pKi 10,07 e 9,31). L'affinità per D3 è superiore all'affinità della stessa dopamina. Cariprazina mostra inoltre un'elevata affinità per i recettori 5-HT2B (pKi 9,24), con antagonismo puro. Cariprazina è un agonista parziale e ha un'affinità significativa, ma inferiore all'affinità per D3, sui recettori 5-HT1A (pKi 8,59). Agendo su D3 e 5-HT1, cariprazina migliora i sintomi negativi, l'anedonia e i deficit cognitivi. L'affinità per i recettori 5-HT2A (pKi 7,73), H1 (pKi 7,63) e 5-HT2C (pKi 6,87) è inferiore, così come minori sono le affinità per i recettori adrenergici, istaminergici e colinergici, recettori che sono spesso responsabili di effetti collaterali. Grazie al profilo di tollerabilità (sicurezza cardiovascolare, bassa probabilità di dare sedazione e iperprolattinemia, basso rischio metabolico), insieme alla sua peculiare efficacia sui sintomi negativi e alla sua lunga emivita, che spesso migliora la scarsa aderenza, cariprazina è un candidato valido per il passaggio da un antipsicotico inefficace (o parzialmente efficace, con particolare riferimento ai sintomi negativi), poco tollerato, o assunto con una scarsa aderenza. Questo articolo esamina le caratteristiche farmacocinetiche e farmacodinamiche di cariprazina e discute le loro implicazioni in termini di identificazione dei pazienti che possano beneficiare di un passaggio a cariprazina, e della migliore strategia per completare lo switch con successo.

The Microbiome: A New Target for Research and Treatment of Schizophrenia and its Resistant Presentations? A Systematic Literature Search and Review.

Background: The gastrointestinal system hosts roughly 1,800 distinct phyla and about 40,000 bacterial classes, which are known as microbiota, and which are able to influence the brain. For instance, microbiota can also influence the immune response through the activation of the immune system or through the release of mediators that are able to cross the brain blood barrier or that can interact with other substances that have free access to the brain, such as tryptophan and kynurenic acid, which is a metabolite of tryptophan and which has been involved in the pathogenesis of schizophrenia. Objectives: This paper reviews the possible relationships between microbiome, schizophrenia and treatment resistance. Given the possibility of a role of immune activation and alterations, we also describe the relationship between schizophrenia and immune inflammatory response. Finally, we report on the studies about the use of probiotic and prebiotics in schizophrenia. Methods: Cochrane library and PubMed were searched from the year 2000 to 2018 for publications about microbiome, immune-mediated pathology, schizophrenia and neurodevelopmental disorders. The following search string was used: (microbiome or immune mediated) AND (schizophrenia OR neurodevelopmental disorder). Associated publications were hand-searched from the list of references of the identified papers. A narrative review was also conducted about the use of probiotics and prebiotics in schizophrenia. Results: There exists a close relationship between the central nervous system and the gastrointestinal tract, which makes it likely that there is a relationship between schizophrenia, including its resistant forms, and microbiota. This paper provides a summary of the most important studies that we identified on the topic. Conclusions: Schizophrenia in particular, remain a challenge for researchers and practitioners and the possibility of a role of the microbiome and of immune-mediated pathology should be better explored, not only in animal models but also in clinical trials of agents that are able to alter gut microbiota and possibly influence the mechanisms of gastrointestinal inflammation. Microbiome targeted treatments have not been well-studied yet in patients with mental illness in general, and with schizophrenia in particular. Nonetheless, the field is well worth of being appropriately investigated.

Using sertraline in postpartum and breastfeeding: balancing risks and benefits.

INTRODUCTION: The World Health Organization recommends newborns to be breastfed but this may be challenging if the mother needs to be treated for depression, since strong evidence to inform treatment choice is missing. AREAS COVERED: We provide a critical review of the literature to guide clinicians who are considering sertraline for the management of depression during postpartum. EXPERT OPINION: Sertraline is one of the safest antidepressants during breastfeeding. In most cases, women already taking sertraline should be advised to breastfeed and continue the medication. We recommend to begin with low doses and to slowly increase the dose up, with careful monitoring of the newborn for adverse effects (irritability, poor feeding, or uneasy sleep, especially if the child was born premature or had low weight at birth). The target dose should be the lowest effective. When feasible, child exposure to the medication may be reduced by avoiding breastfeeding at the time when the antidepressant milk concentration is at its peak. A decision to switch to sertraline from ongoing and effective treatment should be taken only after a scrupulous evaluation of the potential risks and benefits of switching versus continuing the ongoing medication while monitoring the infant carefully.

Feasibility, Adherence and Efficacy of Liraglutide Treatment in a Sample of Individuals With Mood Disorders and Obesity.

Background: Liraglutide is a once-daily injectable medication approved for the treatment of obesity. Hereby we report the feasibility, adherence and efficacy of liraglutide treatment in a sample of individuals with mood disorders and obesity. Methods and Sample: Twenty-nine patients with Bipolar or Major Depressive Disorder received liraglutide once daily subcutaneously at a dose gradually titrated from 0.6 to 3 mg. All patients were obese and had previously failed multiple healthy lifestyle interventions, including exercise and diet programs. Patients' weight was recorded before liraglutide treatment (T0) and then 1 (T1), 3 (T3), and 6 months (T6) following T0. Results: Mean baseline (T0) weight was 110.54 Kg (±24.95). Compared to baseline, the percentage of weight loss was 3.37% at T1, 7.85% at T3, and 10.20% at T6. Thirty-one percent (n = 9) of patients had no side effects, 34.48% (n = 10) had one, 24.14% (n = 7) had two, and 10.34% (n = 3) had three side effects. All 29 subjects were still on liraglutide at T1; 79.31 and 48.28% were on liraglutide at T3 and T6. No significant relationship was found between liraglutide dose and likelihood to continue the medication. No patient showed a worsening of the psychiatric condition due to liraglutide treatment. Acceptability and satisfaction with treatment were good for the 48% that completed the study. Conclusions: Liraglutide treatment was efficacious, accepted and tolerated by ~50% of our sample, followed up for a period of 180 days. Larger, longer, controlled, prospective studies are warranted.
