Possible Use of Minocycline in Adjunction to Intranasal Esketamine for the Management of Difficult to Treat Depression following Extensive Pharmacogenomic Testing: Two Case Reports.

ABSTRACT: The advent of intra-nasal esketamine (ESK), one of the first so called fast-acting antidepressant, promises to revolutionize the management of treatment resistant depression (TRD). This NMDA receptor antagonist has proven to be rapidly effective in the short- and medium-term course of the illness, revealing its potential in targeting response in TRD. Although many TRD ESK responders are able to achieve remission, a considerable portion of them undergo a metamorphosis of their depression into different clinical presentations, characterized by instable responses and high recurrence rates that can be considered closer to the concept of Difficult to Treat Depression (DTD) than to TRD. The management of these DTD patients usually requires a further complex multidisciplinary approach and can benefit from the valuable contribution of new personalized medicine tools such as therapeutic drug monitoring and pharmacogenetics. Despite this, these patients usually come with long and complex previous treatments history and, often, advanced and sophisticated ongoing pharmacological schemes that can make the finding of new alternative options to face the current recurrences extremely challenging. In this paper, we describe two DTD patients-already receiving intranasal ESK but showing an instable course-who were clinically stabilized by the association with minocycline, a semisynthetic second-generation tetracycline with known and promising antidepressant properties.

Project description:BackgroundPreoperative fear and anxiety are prevalent in children undergoing surgery. The combination of esketamine and dexmedetomidine has been proposed as a promising premedication for enhancing preoperative sedation and analgesia. This study compared the premedication efficacy of intranasal esketamine alone and esketamine-dexmedetomidine combination in pediatric patients undergoing strabismus surgery.MethodsOne hundred and eighty preschool children aged 2-6 years scheduled for strabismus surgery were enrolled and randomly assigned to one of the three groups: intranasal premedication with esketamine 2 mg/kg (Group K), esketamine 1 mg/kg and dexmedetomidine 1 µg/kg (Group KD1), or esketamine 0.5 mg/kg and dexmedetomidine 2 µg/kg (Group KD2). The primary outcome was the level of sedation following the intervention, as measured by the modified Yale preoperative anxiety scale (mYPAS) and sedation scale (SS). Secondary outcomes included onset time of sedation, the successful rate of peripheral intravenous cannulation, parental separation anxiety scale (PSAS), mask acceptance scale (MAS), wake-up time, duration of stay in the post-anesthesia care unit (PACU), and premedication-related adverse effects.ResultsAfter premedication, the mYPAS score gradually decreased in the three groups, with lower values in Group K than in Group KD1 and Group KD2 patients in 1, 5, and 10 min. SS in Group KD1 and Group KD2 steadily increased until 40 min after premedication, while SS in Group K increased in the first 5 min after premedication and maintained consistent levels during the remaining time. Sedation onset was substantially faster in Group K patients (11.4±7.8 min) than Group KD1 (18.1±7.5 min, P=0.006) and Group KD2 (18.4±6.8 min, P<0.001). PSAS, separation status, the successful rate of peripheral intravenous cannulation, and MAS were comparable among groups. There was no significant difference in terms of emergence time or duration of stay in the PACU among groups. More gastrointestinal events were observed in Group K (P<0.001).ConclusionsIntranasal premedication with 2 mg/kg esketamine produced a more rapid onset of sedation accompanied by more gastrointestinal reactions compared with a combination of esketamine and dexmedetomidine.Trial registrationClinicalTrials.gov identifier: NCT04757675.

Project description:ObjectiveRecently, several academics have recommended that the concept of difficult-to-treat depression (DTD) should be considered in some of the cases where achieving or maintaining remission of depressive symptoms is not possible. In 2020, a consensus statement, not based on a formal process and systematic review defined difficult-to-treat depression as "depression that continues to cause significant burden despite normal treatment efforts". In addition to addressing symptom control, interventions for DTD should also target other factors, including the management of psychiatric and medical comorbidities, psychosocial functioning, self-esteem, and self-management strategies. The purpose of this scoping review is to explore the scientific literature, which is still unclear and vague, regarding the pathophysiology and treatment of difficult-to-treat depression, providing a summary of its current conceptualization. This represents a cultural and scientific shift that offers clinicians and researchers valid and up-to-date study criteria, thus expanding upon the model of treatment-resistant depression (TRD). Consequently contributions, concepts, theories and gaps of the state of the art in the description of difficult-to-treat depression have been summarized here.MethodA research study was conducted using PubMed, Scopus, PsycINFO, Cochrane Library, and Open Grey databases to identify and examine articles reporting key features related to the recent concept of difficult-to-treat depression. The research covered a period of time between January 1, 2013, and March 1, 2023. Based on a formal checklist, two researchers independently assessed the eligibility criteria to determine which studies to include or exclude in this search. Further data evaluations were conducted for the articles that were deemed to have the most comprehensive descriptions.ResultsThe results of the research yielded a body of literature that provides a clear definition of difficult-to-treat depression and insights into its clinical application and research perspective.ConclusionsDTD represents a cultural and scientific shift that provides clinicians and researchers with valid and up-to-date study criteria that allow the extension of the treatment-resistant depression (TRD) model. The main difference lies in the operational process of assessment and intervention in the depressive syndrome in relation to the search for a therapeutic response. The results of this review show that DTD is a theoretically and clinically useful conceptualization for depressive syndromes that are not just simply resistant to treatment. This clinical condition entails a novel clinical therapeutic approach for specific patients and may be used throughout the world to help recognize this clinical condition while optimizing overall care for these patients. However, as we have highlighted, in the absence of RCTs and further observational studies, it is desirable that DTD be further investigated and defined..

Project description:BackgroundProcedural sedation and analgesia are commonly used in the Emergency Departments. Despite this common need, there is still a lack of options for adequate and safe analgesia and sedation in children. The objective of this study was to evaluate whether intranasal dexmedetomidine could provide more effective analgesia and sedation during a procedure than intranasal esketamine.MethodsThis was a double-blind equally randomized (1:1) superiority trial of 30 children aged 1-3 years presenting to the Emergency Department with a laceration or a burn and requiring procedural sedation and analgesia. Patients were randomized to receive 2.0 mcg/kg intranasal dexmedetomidine or 1.0 mg/kg intranasal esketamine. The primary outcome measure was highest pain (assessed using Face, Legs, Activity, Cry, Consolability scale (FLACC)) during the procedure. Secondary outcomes were sedation depth, parents' satisfaction, and physician's assessment. Comparisons were done using Mann-Whitney U test (continuous variables) and Fisher's test (categorical variables).ResultsAdequate analgesia and sedation were reached in 28/30 patients. The estimated sample size was not reached due to changes in treatment of minor injuries and logistical reasons. The median (IQR) of highest FLACC was 1 (0-3) with intranasal dexmedetomidine and 5 (2-6.75) with intranasal esketamine, (p-value 0.09). 85.7% of the parents with children treated with intranasal dexmedetomidine were "very satisfied" with the procedure and sedation compared to the 46.2% of those with intranasal esketamine, (p-value 0.1). No severe adverse events were reported during this trial.ConclusionsThis study was underpowered and did not show any difference between intranasal dexmedetomidine and intranasal esketamine for procedural sedation and analgesia in young children. However, the results support that intranasal dexmedetomidine could provide effective analgesia and sedation during procedures in young children aged 1-3 years with minor injuries.Trial registrationEudra-CT 2017-00057-40, April 20, 2017. https://eudract.ema.europa.eu/.
